A wire of the coil is connected with a microprocessor control circuit, and on and off of input current and amplitude of the current are controlled by a microprocessor, so that end-expiratory pressure of a patient can be accurately controlled.
Description
Technical field
The present invention relates to a kind of system controlled by computer outlet valve, a kind of device that can step-less adjustment end-tidal pressure, majority is applied to belong to armarium manufacturing technology field on anesthetic machine, the gentle galvanic electricity control of the electric electricing breathing machine respirator.
Background technology
Respirator is mainly used in treatment respiratory failure patient clinically, and anesthetic machine is mainly used in the patient that need do the general anesthesia operation, and in operation and therapeutic process, the pressure of accurately regulating patient's end-tidal according to patient's the state of an illness is significant to patient's treatment.Present technology is most uses mechanical types control, regulates through the pressure of regulating spring, and shortcoming is that control accuracy is low and can not feed back and carry out closed loop control.
Summary of the invention
In order to overcome the defective of prior mechanical outlet valve, the invention provides a kind of system controlled by computer outlet valve, can overcome this defective effectively.
Scheme of the present invention is following:
A kind of system controlled by computer outlet valve; Said outlet valve comprises valve body, diaphragm, tabletting, gland; It is characterized in that: also comprise pressure controller; Said pressure controller comprises outer yoke, inner yoke, coil, Magnet, pressure head and collar, and said inner yoke is positioned at outer yoke, and said Magnet is between outer yoke and inner yoke; Be shaped as a watt shape; Inner yoke is provided with the radially-directed groove, and said coil one end is positioned at said gathering sill, and the other end is provided with pressure head; Collar is positioned at the outer yoke bottom; The gland that outer yoke is provided with screw thread and outlet valve links to each other.
Said Magnet magnetizing direction is a radial magnetizing, one to the N utmost point one to the S utmost point, some blocks of Magnet are uniformly distributed in the outer yoke inner chamber.
The lead of said coil connects microcomputer control circuit, by the break-make of system controlled by computer electrical current and the size of electric current.
When the patient was air-breathing, coil was connected certain electric current, and coil produces force urges pressure head upwards and seals diaphragm in magnetic field, made gas get into patient pulmonary; When the patient exhales, turn-off current, coil is because deadweight is fallen, and diaphragm is opened, thus the patient can exhale smoothly.When the patient exhales, can also be according to patient's the state of an illness, through the current value of microprocessor control coil, thereby control the pressure of patient's end-tidal accurately.

The specific embodiment
Among Fig. 1, system controlled by computer outlet valve provided by the invention comprises valve body 1, diaphragm 2, tabletting 3, gland 4, establishes air inlet 5, gas outlet 6 on the valve body 1, and gas gets into valve body 1 by air inlet 5, is discharged by gas outlet 6 through the passage of diaphragm 2 tops.The system controlled by computer outlet valve also comprises pressure controller; Pressure controller comprises outer yoke 7, inner yoke 8, coil 9, Magnet 10, pressure head 11 and collar 12; Wherein inner yoke 8 is positioned at outer yoke 7; Magnet 10 is between outer yoke 7 and inner yoke 8; Magnet 10 is shaped as a watt shape; Magnetizing direction is a radial magnetizing, one to the N utmost point one to the S utmost point, some blocks of Magnet are uniformly distributed in the outer yoke inner chamber.Inner yoke 8 is provided with radially-directed groove 13, and said coil 9 lower ends are positioned at said gathering sill 13, and said pressure head 11 is positioned at coil 9 upper ends; Gathering sill 13 on the inner yoke 8 makes coil 9 to slide up and down and can not rotate.Collar 12 is positioned at outer yoke 7 bottoms; The gland 4 that outer yoke 7 tops are provided with screw thread and outlet valve links to each other.
The clearer structure that shows pressure controller shown in Figure 2; It comprises outer yoke 7, inner yoke 8, coil 9, Magnet 10, pressure head 11 and collar 12; Said inner yoke 8 is positioned at outer yoke 7; Said Magnet 10 is between outer yoke and inner yoke; Be shaped as a watt shape; Inner yoke is provided with radially-directed groove 13, and said coil 9 lower ends are positioned at said gathering sill 13, and pressure head 11 is positioned at coil 9 upper ends; Collar 12 is positioned at the outer yoke bottom, is used for fixing inner yoke; Coil 9 is connected with external power source through lead 14.Coil 9 is wound on the bobbin, and when feeding DC current in the coil, bobbin produces thrust upwards.The gland that outer yoke top is provided with screw thread and outlet valve links to each other.
Shown in Figure 3; The respirator delivery outlet links to each other with system controlled by computer outlet valve of the present invention and patient through pipeline and three-way body; Gas gets into valve body from air inlet 5, and when patient inhales, coil 9 is connected certain electric current; Coil produces power upwards in magnetic field; Bobbin moves upward along gathering sill 13, and the pressure head 11 of upper end is roof pressure tabletting 3 upwards, makes diaphragm 2 sealing outlet passageways; Gas can't be discharged by gas outlet 6, makes gas get into patient pulmonary; When patient exhales, turn-off current, bobbin is because deadweight is fallen, and diaphragm 2 is opened, and patient expired gas is discharged by the gas outlet, thereby can exhale smoothly.The present invention is by the break-make of system controlled by computer coil electricity electric current and the size of electric current.When patient exhales, can also be according to patient's the state of an illness, through the current value in the microprocessor control coil, thrust that can the control coil frame is regulated the degree of closure of outlet passageway, thereby can accurately be controlled patient's end-tidal pressure.
