Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The flow diagrams depicted in the figures are merely illustrative and do not necessarily include all of the elements and operations/steps, nor do they necessarily have to be performed in the order depicted. For example, some operations/steps may be decomposed, combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an anesthesia ventilation system according to an embodiment of the present application.

As shown in fig. 1, the anesthetic breathing system includes an anesthetic vaporizer, a vaporizer connecting base 110, an air inlet port 120, and an air outlet port 130.

In some embodiments, the anesthetic breathing system includes an anesthetic machine host, and the vaporizer connecting base 110, the air inlet port 120, and the air outlet port 130 are all located in the anesthetic machine host.

In some embodiments, as shown in fig. 1, the anesthetic breathing system further comprises an anesthetic vaporizer 200. In other implementations, the anesthetic breathing system may not include the anesthetic vaporizer 200. The anesthetic vaporizer 200 can be detachably coupled to the vaporizer coupling base 110.

Wherein, the inlet interface 120 and the outlet interface 130 of the anesthesia ventilation system are arranged on the fresh gas branch and are connected with the anesthesia evaporator 200 when the anesthesia evaporator 200 is connected to the evaporator connecting seat 110.

Specifically, as shown in fig. 2 and 3, the anesthesia ventilation system further comprises an in-situ detection device 141 and a controller 142, wherein the in-situ detection device 141 can be connected to the controller 142.

Wherein, the in-place detection device 141 is used for detecting whether the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110. Illustratively, the presence detecting device 141 sends corresponding information to the controller 142 when detecting that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110, so as to inform the controller 142 that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110.

Illustratively, when the controller 142 detects that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110 according to the in-situ detection device 141, it can supply gas to the anesthetic vaporizer 200 through the gas inlet interface 120, and receive anesthetic gas output by the anesthetic vaporizer 200 through the gas outlet interface 130; if it is not detected that the anesthetic vaporizer 200 is connected to the vaporizer connecting section 110, air may not be supplied to the anesthetic vaporizer 200. So that gas leakage can be prevented.

For example, if the controller 142 obtains a ventilation start instruction input by an operator, it may first detect whether the anesthetic vaporizer 200 is in place through the in-place detection device 141, and only when the anesthetic vaporizer 200 is detected to be in place, the controller supplies air to the anesthetic vaporizer 200 through the air inlet 120 and receives anesthetic gas output by the anesthetic vaporizer 200 through the air outlet 130; the controller 142 may stop supplying gas to the anesthetic vaporizer 200 if it receives a stop ventilation command input by the operator or generates a stop ventilation command.

In some embodiments, as shown in fig. 3 and 4, the anesthetic vaporizer 200 includes a main body 210 provided with a first electrical interface 220 and a vaporizer circuit 230 connected to the first electrical interface 220.

Illustratively, vaporizer circuit 230 may control the injection of anesthetic agent to anesthetic vaporizer 200, and/or sense gas pressure, among other processes.

Illustratively, the evaporator circuit 230 may also draw power through the first electrical interface 220, or may also communicate with an external device through the first electrical interface 220.

In some embodiments, as shown in fig. 3 and 4, the anesthesia ventilation system further comprises a second electrical interface 150. When the anesthetic vaporizer 200 is connected to the vaporizer connecting holder 110, the second electrical interface 150 is connected to the first electrical interface 220 of the anesthetic vaporizer 200. Thus, the second electrical interface 150 may provide power to the anesthetic vaporizer 200 through the first electrical interface 220 and communicate with the anesthetic vaporizer 200. At this time, the controller 142 detects that the anesthetic vaporizer 200 is in place by the in-place detection device 141, activates the anesthetic vaporizer, the controller 142 controls to power on the second electrical interface 150, that is, power is supplied to the anesthetic vaporizer 200 through the second electrical interface 150 and the first electrical interface 200, and the controller 142 controls the fresh gas branch to supply gas to the anesthetic vaporizer through the gas inlet interface. Of course, after the on-site detection device 141 detects that the anesthetic vaporizer 200 is on site, the controller 142 may also control to power the second electrical interface 150 first, and to power the anesthetic vaporizer 200 through the second electrical interface 150 and the first electrical interface 200. The controller 142 controls the fresh gas branch to supply gas to the anesthetic vaporizer through the gas inlet interface after receiving the supply anesthetic control signal.

It is understood that the first electrical interface 220 and the second electrical interface 150 include a plurality of electrical connection points, for example, a portion for transmitting electrical energy and another portion for performing communication.

In some embodiments, the presence detection device 141 is connected to the second electrical interface 150, as shown in fig. 3 and 4.

Illustratively, at least one electrical connection point of the second electrical interface 150 is connected to the presence detection device 141.

It is understood that the first electrical interface 220 or the second electrical interface 150 may each include one or more interfaces, for example, different connection points of the same interface may be respectively used for implementing functions of power supply, communication, presence detection, and the like, or multiple interfaces may be respectively used for implementing functions of power supply, communication, presence detection, and the like.

Illustratively, when the anesthetic vaporizer 200 is connected to the vaporizer connecting socket 110, the presence detecting device 141 may be connected to the first electrical interface 220 through the second electrical interface 150 to connect to the vaporizer circuit 230 of the anesthetic vaporizer 200.

In some embodiments, the anesthetic vaporizer 200 may be determined to be connected to the vaporizer connection base 110 if the vaporizer circuit 230 can be detected by the presence detection device 141. When the vaporizer circuit 230 is not detected by the presence detecting means 141, it is determined that the anesthetic vaporizer 200 is not connected to the vaporizer connecting section 110.

Illustratively, the controller 142 may supply power to the anesthetic vaporizer 200 via the second electrical interface 150 upon detection of the vaporizer circuit 230 of the anesthetic vaporizer 200 by the presence detection means 141; when it is not detected that the anesthetic vaporizer 200 is connected to the vaporizer connecting socket 110, the second electrical interface 150 may not be supplied with power.

Illustratively, after the anesthetic vaporizer 200 is powered, the vaporizer circuitry 230 may communicate with the controller 142 of the anesthetic ventilation system via the first electrical interface 220 and the second electrical interface 150.

Illustratively, when the controller 142 detects that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110 according to the presence detecting device 141, it can supply air to the anesthetic vaporizer 200 through the air inlet port 120, and receive anesthetic gas output by the anesthetic vaporizer 200 through the air outlet port 130.

In other embodiments, when the anesthetic vaporizer 200 is connected to the vaporizer connecting seat 110, the presence detection device 141 may detect a state of the vaporizer circuit 230, and the controller 142 may determine that the anesthetic vaporizer 200 is connected to the vaporizer connecting seat 110; the presence detection means 141 may detect another state of the vaporizer circuit 230 when the anesthetic vaporizer 200 is partially connected to the vaporizer connection holder 110. When the anesthetic vaporizer 200 is not connected to the vaporizer connecting socket 110, the vaporizer circuit 230 is not detected by the presence detecting device 141, and the controller 142 can determine that the anesthetic vaporizer 200 is not connected to the vaporizer connecting socket 110.

Illustratively, the anesthetic vaporizer 200 is partially connected to the vaporizer connecting base 110, and includes: although the second electrical interface 150 is connected to the first electrical interface 220 of the anesthetic vaporizer 200, the inlet and

outlet interfaces

120, 130 are not yet stably and completely connected to the anesthetic vaporizer 200. So that there is a risk of leakage of fresh gas and even anesthetic gas at this time.

Illustratively, if the controller 142 detects the other state of the vaporizer circuit 230 by the presence detection means 141, it may be determined that the anesthetic vaporizer 200 is not connected to the vaporizer connecting base 110.

Illustratively, the controller 142 may supply power to the anesthetic vaporizer 200 through the second electrical interface 150 when the vaporizer circuit 230 of the anesthetic vaporizer 200 is in a state where the anesthetic vaporizer 200 is completely connected to the vaporizer connecting section 110 according to the detection of the presence detection means 141; when the vaporizer circuit 230 of the anesthetic vaporizer 200 is not detected or when the vaporizer circuit 230 of the anesthetic vaporizer 200 is detected in a state where the anesthetic vaporizer 200 is not completely connected to the vaporizer connecting section 110, power may not be supplied to the second electrical interface 150.

Illustratively, when the controller 142 detects that the vaporizer circuit 230 of the anesthetic vaporizer 200 is in a state where the anesthetic vaporizer 200 is completely connected to the vaporizer connecting base 110 according to the in-place detection device 141, it can supply gas to the anesthetic vaporizer 200 through the gas inlet interface 120, and receive anesthetic gas output by the anesthetic vaporizer 200 through the gas outlet interface 130; when the vaporizer circuit 230 of the anesthetic vaporizer 200 is not detected or when the vaporizer circuit 230 of the anesthetic vaporizer 200 is detected in a state where the anesthetic vaporizer 200 is not completely connected to the vaporizer connecting section 110, air may not be supplied to the anesthetic vaporizer 200.

In some embodiments, as shown in fig. 3 and 4, the anesthetic vaporizer 200 is provided with a locking member 240, the vaporizer connecting section 110 is provided with a fitting member 160, and the locking member 240 and the fitting member 160 are engaged with each other to lock the anesthetic vaporizer 200 to the vaporizer connecting section 110.

Specifically, when the locking member 240 and the fitting member 160 are engaged with each other to lock the anesthetic vaporizer 200 to the vaporizer connecting section 110, the air inlet port 120 and the air outlet port 130 are stably and completely connected to the anesthetic vaporizer 200.

Illustratively, retaining member 240 includes a locking end 241 disposed at the bottom of body 210, locking end 241 projecting below the bottom of body 210; fitting 160 has an end surface 161 and a latch slot 162 adjacent end surface 161; when the locking end 241 falls into the locking hook groove 162, the anesthetic vaporizer 200 is locked with the vaporizer connecting seat 110.

Illustratively, as shown in fig. 1, the evaporator connecting base 110 is provided with a guide rail 170, the bottom of the anesthetic vaporizer 200 is provided with a sliding groove which is matched with the guide rail 170, and when the anesthetic vaporizer 200 is mounted on the evaporator connecting base 110, the guide rail 170 and the sliding groove are matched with each other to play a positioning role. The locking end 241 of the locking member 240 extends into the sliding groove, the fitting member 160 can be disposed on the guide rail 170, the sliding groove of the anesthetic vaporizer 200 is aligned with the guide rail 170, and the locking member 240 is locked to the fitting member 160 in the process of pushing along the guide rail 170. Specifically, as the anesthetic vaporizer 200 is advanced along the rail 170 via the chute, the locking end 241 slides over the end surface 161 and drops into the latch slot 162.

Illustratively, a sliding groove may also be formed in the evaporator connecting base 110, a guide rail 170 is disposed at the bottom of the anesthetic vaporizer 200, and when the anesthetic vaporizer 200 is mounted on the evaporator connecting base 110, the guide rail 170 and the sliding groove are matched with each other to perform a positioning function.

In some embodiments, the position detecting device 141 may include a fitting state detecting member 231 for detecting the state of the locking member 240 and the fitting member 160. The fitting state detecting member 231 may be disposed near the locker 240, for example, to detect different states of the locker 240 and the fitting member 160 and transmit the detection result to the controller 142. The mating state detecting element 231 may send the detection result to the controller 142 through the first electrical interface 220 and the second electrical interface 150, or may send the detection result to the controller 142 through another electrical interface or in a wireless communication manner. Illustratively, when the locking member 240 and the engaging member 160 are engaged with each other to lock the anesthetic vaporizer 200 to the vaporizer attaching base 110, the locking member 240 puts the engaging state detecting member 231 in the first state, so that the vaporizer circuit 230 is in a state where the anesthetic vaporizer 200 is completely attached to the vaporizer attaching base 110; when the locker 240 and the fitting member 160 are not fitted to each other, the fitting state detecting member 231 is in the second state, so that the vaporizer circuit 230 is in a state where the anesthetic vaporizer 200 is not completely connected to the vaporizer connecting section 110.

Illustratively, it is determined that the anesthetic vaporizer 200 is detected to be connected to the vaporizer connecting section 110 when the fitting state detecting member 231 is detected to be in the first state by the position detecting means 141; the non-detection of the fitting state detection member 231 in the first state determines that the connection of the anesthetic vaporizer 200 to the vaporizer connecting section 110 is not detected, including, for example, the non-detection of the vaporizer circuit 230 or the detection of the fitting state detection member 231 in the second state.

Illustratively, the fitting state detecting member 231 may include a mechanical switch, as shown in fig. 3 and 4, disposed above the locking end 241. As shown in fig. 4, the anesthetic vaporizer 200 is pushed along the guide rail 170 through the chute, and when the lower side of the locking end 241 abuts against the end surface 161, the upper side of the locking end 241 abuts against the mechanical switch, so that the mechanical switch is in the second state; as shown in fig. 3, the locking member 240 releases the mechanical switch when the locking end 241 slides down into the locking hook slot 162, so that the mechanical switch is in the first state.

Specifically, the mechanical switch may include a micro switch, and the upper side of the locking end 241 abuts against the micro switch or releases the micro switch, so that the micro switch may be in an on/off or off/on state, respectively. Illustratively, the presence detection device 141 may further include a circuit for detecting the state of the micro switch, and the circuit may include a pull-up resistor having one end connected to the high level and the other end connected to the controller 142. The controller 142 can determine whether the anesthetic vaporizer 200 is connected to the vaporizer connecting socket 110 by the level of the circuit of the presence detecting device 141.

For example, the fitting state detecting member 231 may further include a sensor sensitive to a magnetic field, such as a reed switch, a hall sensor, etc., which is disposed above or below the locking end 241, and the locking end 241 may be provided with a permanent magnet, for example. When the lower side of the locking end 241 abuts against the end surface 161, the locking end 241 is located at a relatively upper position, and the sensor can output a signal corresponding to the first state to the in-place detection device 141; when the locking end 241 falls into the locking hook groove 162, the locking end 241 is located at a relatively lower position, and the sensor can output a signal corresponding to the second state to the in-place detection device 141. Illustratively, the presence detecting device 141 may include a circuit for detecting the state of the reed switch, or a circuit for amplifying the output voltage of the hall sensor.

Illustratively, the fitting state detecting member 231 may include a light emitting element and a photosensitive element, for example, an infrared ray emitting tube and an infrared ray receiving tube, and the photosensitive element may output, for example, a high level upon receiving light from the light emitting element. The locking end 241 may be provided with a shielding member capable of blocking the light emitted from the light emitting device from being transmitted to the light receiving device. When the lower side of the locking end 241 abuts against the end surface 161, the shielding member blocks the light of the light emitting element from transmitting to the light sensing element; when the locking end 241 falls into the locking hook groove 162, the shielding member does not block the light of the light emitting element from transmitting to the light sensing element. Or when the locking end 241 falls into the locking hook groove 162, the shielding piece blocks the light of the light-emitting element from transmitting to the photosensitive element; when the lower side of the locking end 241 abuts against the end surface 161, the shielding member does not block the light of the light emitting element from transmitting to the light receiving element. Illustratively, the in-place detection device 141 may include a circuit for detecting the output voltage of the photosensitive element.

Of course, in the specific implementation, the installation positions of the on-site detection device 141 and the disposition state detection element 231 may be adjusted between the anesthetic vaporizer 200 and the vaporizer connection base 110 as needed. The adjustment herein also includes the position adjustment of the subassembly in the position detection device 141 or the configuration status detection element 231, for example, a part of the subassembly in the position detection device 141 or the configuration status detection element 231 may be disposed on the anesthetic vaporizer 200, and another part of the subassembly may be disposed on the vaporizer connecting seat 110.

In some embodiments, the anesthetic vaporizer 200 may further include a gripping structure 211 provided on the body 210, which may be a handle, a groove, or the like, to facilitate gripping of the anesthetic vaporizer 200 by a user. The anesthesia ventilation system may further comprise an unlocking means 212 for unlocking the locking relationship between the anesthesia vaporizer 200 and the vaporizer adaptor base 110, and the unlocking means 212 may be provided on the anesthesia ventilation system, the vaporizer adaptor base 110 or the anesthesia vaporizer 200.

Illustratively, as shown in fig. 3-5, the body 210 is formed with a gripping structure 211, such as a handle. An unlocking means 212 may for example be provided at said grip structure 211. For example, a receiving cavity is formed inside the holding structure 211, the locker 240 may be received in the receiving cavity, and the locker 240 is rotatably coupled to an inner wall of the holding structure 211.

Illustratively, the unlocking device 212 is coupled to or abuts the locking member 240, and the unlocking device 212 can rotate the locking member 240.

Specifically, as shown in fig. 5, when the operator grasps the grip 211, the unlocking device 212 is operated to rotate the locking member 240, so that the locking end 241 of the locking member 240 is lifted up from the locking hook groove 162, thereby facilitating the installation of the anesthetic vaporizer 200 on the vaporizer connecting base 110 or the removal of the anesthetic vaporizer 200 from the vaporizer connecting base 110. After the anesthetic vaporizer 200 is mounted in place, the operator releases the unlocking device 212, and the locking end 241 of the locking member 240 can be locked in the locking hook groove 162 of the vaporizer connecting base 110.

Illustratively, when the operator grasps the grasping structure 211, the unlocking device 212 is operated to rotate the locking member 240, so that the locking end 241 of the locking member 240 is lifted from the locking hook groove 162 and the engagement state detector 231 is in the second state. For example, when the locking member 240 is rotated, the upper side of the locking end 241 can abut against the mechanical switch to make the mechanical switch in the second state. The controller 142 may determine that the anesthetic vaporizer 200 is tending to disengage from the vaporizer attachment base 110, may disconnect power to the second electrical port 150, stop supplying gas to the anesthetic vaporizer 200, etc.

Illustratively, as shown in fig. 3 to 5, the unlocking device 212 includes a pressing portion 2121 provided on the grasping structure 211, and the locking member 240 may abut against the pressing portion 2121. When the operator grasps the holding structure 211, he can act on the pressing portion 2121 to rotate the locking member 240.

Illustratively, the unlocking device 212 further includes a first elastic member 2122, which can be disposed between the pressing portion 2121 and a sidewall of the grasping structure 211 to facilitate the resetting of the pressing portion 2121.

In some embodiments, as shown in fig. 3-5, the locking member 240 further includes a free end 242 that mates with the pressing portion 2121, and the pressing portion 2121, when pressed, moves the free end 242, causing the locking member 240 to rotate to disengage the locking end 241 from the latch slot 162.

Illustratively, retaining member 240 includes free end 242 and locking end 241 that are angularly disposed, and the junction of free end 242 and locking end 241 is pivotally connected to the sidewall of gripping structure 211. The locking end 241 cooperates with the fitting 160 on the vaporizer connecting holder 110 to lock the connection of the anesthetic vaporizer 200 to the vaporizer connecting holder 110. By pressing the pressing portion 2121, the free end 242 can be triggered to drive the locking member 240 to rotate, so that the locking end 241 is separated from the engaging member 160, thereby unlocking. To facilitate repositioning of retaining member 240, a second resilient member 2123 may be provided between retaining member 240 and the sidewall of gripping structure 211.

Illustratively, the free end 242 and the locking end 241 may be a unitary structure, and alternatively, the free end 242 and the locking end 241 may be separate structures having a connecting relationship.

Of course, the unlocking device 212 may also include a physical key and/or a virtual key for receiving the unlocking command, for example, through an unlocking key or a virtual key on the touch screen. Alternatively, the unlocking command may be issued by the controller 142, for example, when the anesthesia ventilation system, the anesthesia vaporizer, or the user inputs the unlocking control information, the controller 142 sends the unlocking command to the unlocking device 212. The unlocking device 212 unlocks the locking relationship between the anesthetic vaporizer 200 and the vaporizer connecting seat 110 after receiving the unlocking command. The components of the unlocking device 212 can be distributed on the anesthetic vaporizer 200, the vaporizer connecting base 110 and the anesthesia machine main body according to the requirement.

In some embodiments, when the anesthetic vaporizer 200 is mounted to the vaporizer connecting mount 110, the fitting state detecting member 231 is in the second state; when the anesthetic vaporizer 200 is moved continuously to the direction of the vaporizer connecting seat 110, the first electrical interface 220 and the second electrical interface 150 are connected first, then the air inlet interface 120, the air outlet interface 130 and the anesthetic vaporizer 200 are connected and sealed, then the locking end 241 falls into the locking hook groove 162, the matching state detecting element 231 is in the first state, and then the vaporizer connecting seat 110 outputs power to the anesthetic vaporizer 200. For example, after the locking end 241 falls into the locking hook groove 162, the anesthetic vaporizer 200 may continue to move toward the vaporizer connecting seat 110 by a predetermined distance as a margin; when the pushing of the anesthetic vaporizer 200 is stopped, the anesthetic vaporizer 200 can be properly retracted, but the connection of the inlet port 120, the outlet port 130 and the anesthetic vaporizer 200, and the connection of the first electrical port 220 and the second electrical port 150 are still stable and reliable.

Illustratively, as shown in fig. 6, the relative position relationship between the locking member 240 and the fitting member 160 when the anesthetic vaporizer 200 is mounted on the vaporizer connecting holder 110 is schematically shown, wherein a to H are different positions of the locking end 241 of the locking member 240 on the fitting member 160.

When the anesthetic vaporizer 200 is not connected to the vaporizer connecting socket 110 at the position a, the first electrical interface 220 and the second electrical interface 150 are not connected, the vaporizer circuit 230 of the anesthetic vaporizer 200 is not detected by the presence detecting device 141, and the second electrical interface 150 does not output power.

At the position B, the locking end 241 climbs along a slope toward the end surface 161 of the fitting 160, and when the locking end 241 climbs to the end surface 161 at the position C, the fitting state detecting piece 231 is in the second state. When the locking end 241 advances along the end surface 161, the first electrical interface 220 and the second electrical interface 150 are connected at the position D, and the controller 142 detects that the mating state detecting element 231 is in the second state by the presence detecting device 141, so that the second electrical interface 150 does not output electric energy; the inlet port 120, outlet port 130 and anesthetic vaporizer 200 are then sealed in place at location E. When the locking end 241 falls into the locking hook groove 162 at the position F and the position G, the fitting state detector 231 is in the first state, and the controller 142 detects that the fitting state detector 231 is in the first state through the on-site detection device 141, the vaporizer connecting base 110 outputs power to the anesthetic vaporizer 200. Between position G and position H is a margin retract stroke.

When the operator removes the anesthetic vaporizer 200 from the vaporizer attaching base 110, the operator grasps the grasping structure 211 to lift the locking end 241 of the locking member 240 from the locking hook groove 162, and at the same time, the controller 142 detects the second state of the fitting state detecting member 231 by the on-site detecting means 141, and the second electrical port 150 disconnects the power supply to the anesthetic vaporizer 200. After the locking end 241 of the locking member 240 is lifted up from the locking hook groove 162, the anesthetic vaporizer 200 can be moved out from the vaporizer connecting seat 110, and in the moving-out process, the matching state detecting member 231 is always in the second state, and the anesthetic vaporizer 200 is not powered on. Thus also ensuring safety during removal.

The locking end 241 of the locking piece 240, the matching state detection piece 231, the locking hook groove 162, the electric connector, the air connector and the like are arranged, so that the anesthetic evaporator 200 is effectively and reliably locked, the evaporator connecting seat 110 is electrified for the anesthetic evaporator 200 after the air connector is sealed, and safe and reliable plugging is realized.

Further, the anesthetic breathing system may further include a locking structure disposed on the vaporizer connecting base 110 or the anesthetic vaporizer 200, wherein the controller 142 detects that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110, and controls the locking structure to lock the anesthetic vaporizer 200 to the vaporizer connecting base 110. In some embodiments, as shown in fig. 1, 7-10, the evaporator attachment base 110 further comprises a locking structure 180. When the controller 142 detects that the anesthetic vaporizer 200 is connected to the vaporizer connecting base 110, the locking structure 180 is controlled to lock the anesthetic vaporizer 200.

Illustratively, the locking structure 180 may include a locking element 181 capable of telescopic movement. The controller 142 can control the locking element 181 to extend into the bottom of the anesthetic vaporizer 200 to limit the movement of the anesthetic vaporizer 200 relative to the vaporizer connecting section 110.

In some embodiments, the locking structure 180 locks the anesthetic vaporizer 200, in particular: the locking structure 180 locks the locking member 240 and the engaging member 160 to each other, so as to restrict the movement of the locking member 240 relative to the engaging member 160, and lock the anesthetic vaporizer 200 to the vaporizer connecting section 110.

Illustratively, the press fit of the locking structure 180 to the locking member 240 restricts the movement of the locking member 240 relative to the engaging member 160.

Illustratively, the locking structure 180 can act on the locking member 240 to limit rotation of the locking member 240, such that when the operator grasps the gripping structure 211, rotation of the locking member 240 is limited, and the interaction of the locking member 240 and the engagement member 160 can be locked in a locked state. The operator cannot press the pressing part 2121 to unlock, so that misoperation is effectively avoided, and the operator can be reminded that the anesthetic vaporizer 200 is in a working state at the moment.

Illustratively, as shown in fig. 7 and 8, the locking structure 180 includes a movable locking element 181, and the locking element 181 may be movable, for example, in a horizontal direction or a vertical direction. The controller 142 can control the locking element 181 to abut against the locking element 240 to limit the rotation of the locking element 240. Specifically, after the locking structure 180 is activated, the locking element 181 moves toward the direction close to the locking element 240, and the end of the locking element 181 can be pressed on the locking element 240, so as to lock the anesthetic vaporizer 200.

Of course, the locking structure 180 may be partially disposed on the vaporizer connecting base 110, and the other portion is disposed on the anesthetic vaporizer 200.

In some embodiments, as shown in fig. 9 and 10, the anesthetic vaporizer 200 may further comprise a pressing member 250 disposed on the main body 210, the pressing member 250 being movably connected to the main body 210; the locking structure 180 can push the pressing member 250, so that the pressing member 250 is pressed on the locking end 241 of the locking member 240 to limit the rotation of the engaging member 160.

Illustratively, the anesthetic vaporizer 200 may further comprise a reduction element (not shown) coupled to the compression member 250. As shown in fig. 9, the pressing member 250 is rotatably coupled to the main body 210, and the restoring member is fixedly coupled to the main body 210. Specifically, the locking structure 180 can drive the pressing member 250 to rotate, so that the pressing member 250 presses the locking member 240 onto the engaging member 160.

Illustratively, the bottom of the main body 210 is formed with a mounting groove, and the pressing member 250 may be received in the mounting groove and rotatably coupled to a sidewall of the mounting groove. After the locking structure 180 is started, the locking structure moves towards the anesthetic vaporizer 200, and when the pressing member 250 is pushed to rotate to the horizontal position, the pressing member 250 is pressed on the locking end 241. It is understood that, as an alternative to this embodiment, the locking structure 180 drives the pressing member 250 to rotate, so that the pressing member 250 is pressed onto the fitting member 160, and the anesthetic vaporizer 200 can also be locked by the locking structure 180.

Illustratively, the compression member 250 may be slidably coupled to the body 210. As shown in fig. 10, the bottom of the main body 210 is formed with a mounting groove, the pressing member 250 is received in the mounting groove and slidably connected to the bottom wall of the mounting groove, and after the locking structure 180 is activated, the pressing member 250 is moved in the vertical direction to push the pressing member 250 to move toward the locking member 240 until the pressing member 250 presses the locking end 241. It is understood that, as an alternative to this embodiment, the locking structure 180 can push the pressing member 250 to press against the fitting member 160, and the locking of the anesthetic vaporizer 200 by the locking structure 180 can also be realized.

In some embodiments, the locking structure 180 may be an air control; in other embodiments, the locking structure 180 may be an electrically controlled device.

Illustratively, the lock 180 locks or unlocks the anesthetic vaporizer 200 as controlled by the controller 142. For example, the locking structure 180 locks or unlocks the mutual engagement of the locker 240 and the engaging member 160 according to the control of the controller 142.

Illustratively, the controller 142 can control the activation of the locking mechanism 180 to push the pressing member 250 to press against the locking member 240 or the engaging member 160 to lock the anesthetic vaporizer 200. Illustratively, the controller 142 can control the closure structure 180 to close to release the pressing of the pressing member 250 on the locking member 240 or the engaging member 160.

Illustratively, after the anesthetic vaporizer 200 is mounted in place on the vaporizer connecting base 110, the locking end 241 of the locking element 181 is engaged with the fitting element 160, and the locking element 181 and the fitting element 160 realize a first reclosure. For example, power is supplied to the anesthetic vaporizer 200 through the vaporizer connecting base 110 to activate the anesthetic vaporizer 200, and the locking structure 180 can be activated to further lock the anesthetic vaporizer 200 to achieve the double locking. When the anesthetic vaporizer 200 is activated, for example, when gas is taken from the gas inlet port 120 and anesthetic gas is output to the gas outlet port 130, the locking structure 180 keeps locking the anesthetic vaporizer 200, so that the anesthetic vaporizer 200 can be prevented from being separated from the vaporizer connecting seat 110 due to misoperation of an operator.

Illustratively, when it is desired to remove the anesthetic vaporizer 200, the controller 142 controls the anesthetic vaporizer 200 to stop, and may also send a closing signal to the locking structure 180 to release the restriction on the locking member 240, e.g., the pressing member 250 may be moved away from the locking member 240 by the reset element to release the locking end 241 of the locking member 240; through pressing the pressing part 2121, the locking member 240 is driven to rotate, so that the locking end 241 is separated from the fitting member 160, the anesthetic vaporizer 200 can be detached from the vaporizer connecting seat 110, and can be unlocked through one-hand operation, and the operation is convenient and fast.
