Fig. 1 to 3 show an embodiment of a detection probe for a maternal-fetal monitoring device according to the present invention.
As shown in fig. 2, the detection probe for the maternal and fetal monitoring device (herein abbreviated as "detection probe") comprises a probe housing 4, a uterine contraction pressure sensor 5, a lead wire 3, an electrocardio electrode 2, a front-end signal acquisition circuit 6, a main control circuit 7 and a display screen 8. The probe shell 4 is of a circular disc-shaped structure and comprises two circular end faces and a circular ring, wherein the two circular end faces are oppositely arranged at a certain distance, the circular ring is connected with the peripheral edges of the two circular end faces, and the circular end faces and the circular ring surround to form a closed installation space. As can be seen from fig. 1, when the probe housing 4 is attached to the abdomen of a pregnant woman, one of the circular end faces, which is called the inner end face, and the other circular end face, which is called the outer end face, faces the outer side.
The uterine contraction pressure sensor 5, the front end signal acquisition circuit 6 and the main control circuit 7 are arranged in the installation space. The display screen 8 is electrically connected with the main control circuit 7, and displays corresponding contents under the drive of the main control circuit 7. The display screen 8 is arranged on the front surface of the circular shell of the probe shell 4, namely, when the detection probe is bound on the pregnant woman, the display screen 8 is positioned on the circular end surface of the probe shell 4 facing the outer side, so that the monitoring result in the monitoring process can be conveniently read. The probe housing 4, the front end signal acquisition circuit 6, the main control circuit 7 and the display screen 8 are collectively referred to as a probe body 1.
The uterine contraction pressure sensor 5 is arranged at the middle position of the inner side end surface of the probe shell 4 and comprises a sensor body positioned in the installation space and a detection end penetrating through the inner side end surface and extending out to be in contact with the pregnant woman. The front-end signal acquisition circuit 6 is electrically connected with the uterine contraction pressure sensor 5 in the installation space and acquires the uterine contraction pressure signal in real time. The main control circuit 7 is connected with the front-end signal acquisition circuit 6, and the front-end signal acquisition circuit 6 transmits the acquired uterine contraction data to the main control circuit 7 for analysis and calculation, so that a uterine contraction pressure value is obtained.
In this embodiment, the uterine contraction pressure sensor 5 adopts a Wheatstone bridge type stress meter. When the diameter of the abdominal wall of the pregnant woman changes due to the uterine contraction of the pregnant woman, the stress gauge on the uterine contraction pressure sensor 5 causes the pressure deformation of the reed of the Wheatstone bridge circuit through the ejector pin, so that the resistance value of the pressure strain gauges at the two sides of the reed changes, voltage is applied to the bridge, then the change of the resistance is converted into the change of the voltage, the voltage is sampled through AD, uterine contraction pressure signal data can be obtained, and then a pressure calculation program calculates a uterine mechanical pressure value according to the acquired uterine contraction pressure signal.
Obviously, the technical scheme can also adopt other types of uterine contraction pressure sensors 5, and the uterine contraction pressure can be detected by contacting with the abdomen of the pregnant woman.
The electrocardio electrode 2 is connected to a front-end signal acquisition circuit 6 inside the probe shell 4 through a lead wire 3. In such design, the front-end signal acquisition circuit 6 can synchronously acquire mother-fetus mixed signals in real time through the electrocardio-electrode 2 attached to the body of a pregnant woman, and transmits the acquired signals to the main control circuit 7 for analysis and calculation, so that the mother-fetus mixed electrocardio-signals are separated to obtain mother electrocardio-signals and fetal electrocardio-signals, the mother heart rate is calculated according to the mother electrocardio-signals, and the fetal heart rate is calculated according to the fetal electrocardio-signals.
The main control circuit 7 is electrically connected with the display screen 8, and controls the display screen 8 to display the calculation results of the maternal heart rate, the fetal heart rate and the uterine contraction pressure. In this embodiment, the display screen 8 is disposed in the installation space and exposed through the outer end face. The outer end face is also provided with a binding belt buckle matched with the binding belt, and the detection probe is bound on the abdomen of the pregnant woman through the matching of the binding belt and the binding belt buckle.
Referring to fig. 3, the electrocardiograph electrodes 2 are disposed in the upper and lower abdomen regions, and include a first region electrode and a second region electrode disposed corresponding to the upper and lower abdomen regions, respectively. The electrocardio-electrode 2 can select different lead modes according to measurement requirements, and then a plurality of electrocardio-electrodes 2 corresponding to different placement positions are adopted. It is obvious that the first area electrode and the second area electrode are not limited to the arrangement of the areas corresponding to the upper abdominal area and the lower abdominal area, but may be arranged in a left-right area, for example, or may be divided into two detection areas, or may be divided into a plurality of detection areas, and may include a plurality of area electrodes accordingly.
In this embodiment, 3 electrocardiograph electrodes 2 are respectively disposed on the first area electrode and the second area electrode, the included angles between the directions of the 3 electrocardiograph electrodes 2 in the first area electrode and the horizontal axis are 45 °, 90 °, 135 °, and the included angles between the directions of the 3 electrocardiograph electrodes 2 in the second area electrode and the horizontal axis are 225 °, 270 °, 315 °. It is obvious that the number and specific arrangement angle of the electrocardiograph electrodes 2 are only one preferred embodiment in the present technical solution, and it is obvious that the present solution is not limited to the number and angle.
The probe housing 4 is divided into a first end portion located above and a second end portion located below with respect to the horizontal axis. The first end and the second end are respectively provided with a wire outlet structure. The first end of the probe housing 4 is located in the upper abdominal region and the second end is located in the lower abdominal region. The first regional electrode cluster is connected to the front end signal acquisition circuit 6 in the installation space through the wire outlet structure of the first end of the probe housing 4, and the second regional electrode cluster is connected to the front end signal acquisition circuit 6 in the installation space through the wire outlet structure of the second end of the probe housing 4. The wire outlet structure limits the trend of the lead wire 3, and leads the lead wire 3 to point to the target placement position of the electrocardio electrode 2 connected with the lead wire 3 in the direction of extending out of the probe shell 4. The wire outlet structure is a circular pipe structure, a wire slot structure and the like which are arranged on a circular ring in the probe shell 4 and extend along a certain length along the design direction, and the wire outlet direction of the lead wire 3 can be limited.
So designed, when the uterine contraction pressure sensor 5 is fixed on the abdomen of the pregnant woman, the direction in which the lead wire 3 extends out of the probe shell 4 is indicated by the arrangement of the wire outlet structure, so that a user can rapidly position the position of the electrocardio electrode 2 and the lead wire 3 required to be used, the situations of inaccurate position, wrong position and the like of the electrocardio electrode 2 are avoided, and the working efficiency is improved.
The working flow of the detection probe for the maternal and fetal monitoring device provided by the invention is as follows:
