Description

Technical Field

[0001] The present invention relates to the technical field of intelligent medical devices, and in particular to an obstetric pelvic measurement and evaluation system. Background Art

[0002] When the fetus is delivered from the mother's body, it must pass through the pelvis. In addition to the soft birth canal formed by the uterus, cervix, vagina and vulva, the pelvis is the most important component of the birth canal; the speed and smoothness of delivery are closely related to the size and shape of the pelvis. A narrow or deformed pelvis can cause dystocia. Pregnant women and pregnant women with a history of dystocia should undergo routine pelvic measurements and examinations during the first prenatal check-up. Pelvic measurements include external pelvic measurements and internal pelvic measurements. When performing external pelvic measurements, a special pelvic measuring instrument and pelvic measuring ruler are used. They are mainly used to measure the inter-iliac spine diameter, inter-iliac crest diameter, sacropubic external diameter, ischial tuberosity diameter, pubic arch angle, etc.; a measuring instrument used in this application is such as Figure 1 As shown, it includes a measuring foot 11, a dial 12, and a pointer 13; wherein, during the measurement process, according to the different diameters to be measured, the pregnant woman needs to adjust the corresponding body position according to the doctor's requirements, such as supine position, legs bent, hands hugged, left side lying, etc.

[0003] However, the following technical problems still exist in the measurement process: usually, the measurement readings are recorded by one operator, but for outpatient examination departments, there are a large number of pregnant women who come for prenatal examinations to measure their pelvises every day, and the operator needs to quickly and accurately read the readings in a short period of time and record or remember the measured data; among them, for novice operators, usually one data is recorded after each measurement, and for skilled operators, the measurement data is generally remembered during the measurement process, and after the measurement is completed, the remembered data is uniformly entered into the computer system to create a file for the pregnant woman; however, many pregnant women need to be measured in one day, and the above operation process is cumbersome, and fatigue is easy to occur when reading, which may lead to incorrect measurement data. Summary of the invention

[0004] The present invention is intended to provide an obstetric pelvic measurement and evaluation system to solve the problem that the existing pelvic measurement process is cumbersome to operate and the operator may experience reading fatigue after measuring multiple pregnant women for a long time.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A pelvic measurement and evaluation system for obstetrics includes an evaluation system and a reading control unit. The evaluation system includes an input module, an evaluation control unit, and an output module. The input module is used to transmit measurement data to the evaluation control unit. After the evaluation control unit processes and analyzes the received data, the evaluation result is output through the output module. The reading control unit is arranged on the measuring instrument through a reading dial to assist operators in reading quickly. The reading control unit includes a trigger, a timing module, a control module, and a voice module. The trigger is electrically connected to the timing module, and the timing module and the voice module are electrically connected to the control module. The reading dial is installed on the dial of the measuring instrument. The reading dial The measuring device is provided with scale marks corresponding to the scale lines on the dial one by one, and a lamp bead is provided under each scale mark, and the lamp bead is electrically connected to the control module; the trigger includes a metal conductive sheet and a metal trigger sheet, the metal conductive sheet is arranged along the scale marks on the reading dial, and the metal trigger sheet is arranged on the pointer of the measuring device; when the measuring foot is opened to measure the pelvis, the pointer rotates on the dial, the metal trigger sheet on the pointer contacts the metal conductive sheet and triggers the timing module to start timing, when the timing reaches the set time, the timing module sends a signal to the control module, the control module controls the lamp bead at the position where the pointer stops to light up, and turns on the voice module, and the voice module is used as an input module after being turned on.

[0007] Beneficial effects:

[0008] 1. By setting a reading control unit on the pelvis measuring instrument, it is helpful to assist operators to read the data quickly and accurately; when the measuring foot sets the two measuring points, the pointer stays on a certain scale, and the light beads on the corresponding scale light up, which serves as a reminder. For operators who frequently measure multiple pregnant women for a long time, the auxiliary role of the light beads can reduce reading fatigue, thereby improving the efficiency and accuracy of reading.

[0009] 2. By setting up the voice module, the subsequent recording process can be simplified. When the lamp is on and the voice module is turned on, the operator can quickly read the measured data. The voice module also collects the data read by the operator and transmits the collected data to the evaluation control unit. When the measurement is completed, all the measurement data are recorded at the same time. There is no need to enter the measurement data into the computer system separately, which makes the operation simpler and more convenient. The voice module is only turned on when the lamp is on, which can reduce the interference and influence of noise.

[0010] 3. Since the pointer will move on the dial when the measuring foot is opened, the timing module can be set so that the corresponding lamp bead will light up only when the pointer stays at a certain position, which can further improve the accuracy of measurement and reduce the chance of misreading; when the metal trigger sheet on the pointer contacts the metal conductive sheet to form a closed circuit, the timing module starts timing, and the set time can be set to 2-5s according to the proficiency of different personnel. For example, for skilled operators, the positioning of the measuring foot can be completed quickly. At this time, the set time can be 2s. When 2s is reached, the timing module sends a signal to the control module, and the control module controls the lamp bead at the position where the pointer stays to light up; for unskilled operators, the set timing time can be 4s, 5s, etc.

[0011] 4. By setting up the evaluation system, when the voice module transmits the collected data signal to the evaluation control unit, the evaluation control unit can process and analyze the received data. After completing the measurement, the operator can inform the pregnant woman of the evaluation results and explain the meaning of the results to her.

[0012] Preferably, as an improvement, the output module includes a display module and a printing module; the evaluation control unit stores standard values ​​of pelvic measurement data, and when the voice module collects measurement data, the measurement data is sent to the evaluation control unit, and the evaluation control unit compares the input measurement data with the corresponding standard value, and sends the evaluation result to the display module for display and prints it through the printing module.

[0013] Preferably, as an improvement, it also includes a bag taking and disinfecting device, which includes a main body and a bag taking area, a disinfecting area, and a controller arranged on the main body. The bag taking area is used to remove the disposable sterile film on the measuring foot, and the disinfecting area is used for disinfecting the hands of the operator; the main body is also provided with a first indicator light and a second indicator light electrically connected to the controller, the first indicator light is located in the bag taking area, the second indicator light is located in the disinfecting area, and a detector is also provided in the bag taking area, and the detector is electrically connected to the controller; when the measuring foot is placed in the bag taking area and the detector is triggered, the detector sends a signal to the controller, and the controller controls the second indicator light to light up to instruct the operator to disinfect his hands, and when the operator's hands leave the disinfecting area, the controller controls the first indicator light up.

[0014] Beneficial effects:

[0015] 1. In order to ensure clean and hygienic measurement, the pelvic measuring instrument of the present application is put on a disposable sterile film on the measuring foot during actual use. By setting a bag removal and disinfection device, the disposable sterile film after use can be automatically removed; that is, after use, it is only necessary to put the measuring foot of the measuring instrument into the bag removal area. At this time, the operator can help the pregnant woman stand up from the examination bed, which is easier to use than manually removing the sterile film on the measuring foot.

[0016] 2. By setting a disinfection area on the bag taking and disinfection device, operators can disinfect their hands; and indicator lights are set in the bag taking area and the disinfection area to guide users, making the process more standardized; that is, when the measurement is completed, the operator first puts the measuring instrument into the bag taking area, and when the measuring foot is in place, the detector is triggered, indicating that the measuring instrument is correctly placed; at this time, the detector sends a signal to the controller, and the controller controls the second indicator light to light up, reminding the operator to disinfect his hands. When the hand disinfection is completed, the first indicator light is on, indicating that the measuring instrument can be taken out from the bag taking area; thereby, hand disinfection and automatic bag taking are realized, and the measuring instrument is taken out after the hand disinfection is completed, which can make the operation process more standardized.

[0017] Preferably, as an improvement, a bag taking channel and a bag taking assembly are provided in the bag taking area, the opening of the bag taking channel faces the front of the main body, and the detector is arranged at the bottom of the bag taking channel; the bag taking assembly includes a negative pressure suction cup arranged in the bag taking channel, the negative pressure suction cup is used to adsorb the disposable sterile film on the measuring foot, and when the first indicator light is on, the controller controls the negative pressure suction cup to turn on.

[0018] Beneficial effects: When in use, directly extend the measuring foot of the measuring instrument from the opening of the bag taking channel to the bottom. When it touches the detector at the bottom, it indicates that the position is properly placed, and the second indicator light located in the disinfection area lights up. A negative pressure suction cup is provided to adsorb the sterile film on the measuring foot, and when the first indicator light is on, the negative pressure suction cup is turned on. At this time, the measuring foot is taken out from the bag taking channel. Since the negative pressure suction cup adsorbs and fixes the sterile film, the sterile film remains in the bag taking channel, thereby realizing automatic removal of the sterile film.

[0019] Preferably, as an improvement, a vertical channel connected to the bottom of the bag taking channel is also provided in the main body, and a recovery box is provided at the bottom of the vertical channel; the negative pressure suction cup is located at the junction of the bag taking channel and the vertical channel, and the negative pressure suction cup is fixed to the upper side wall of the bag taking channel by a telescopic part.

[0020] Beneficial effect: when the measuring instrument is taken out from the bag taking channel, the negative pressure suction cup is closed, and the sterile film falls from the vertical channel to the recycling box for collection; wherein, the negative pressure suction cup is fixed by a telescopic part, and when the sterile film is stuck in the vertical channel, the telescopic part can be used to drive the negative pressure suction cup to move, thereby pushing the stuck sterile film into the recycling box.

[0034] Embodiment 1

[0035] like Figure 2-3As shown, a pelvic measurement and evaluation system for obstetrics includes an evaluation system and a reading control unit, such as Figure 2 As shown, the evaluation system includes an input module, an evaluation control unit, and an output module. The input module is used to transmit the measurement data to the evaluation control unit. After the evaluation control unit processes and analyzes the received data, the evaluation result is output through the output module. The output module of this embodiment includes a display module and a printing module. Specifically, the display module is a display screen, and the printing module is a printer. The evaluation control unit stores the standard values ​​(normal range values) of the pelvic measurement data, wherein the normal value of the inter-iliac spine diameter is 23-26cm, the normal value of the inter-iliac crest diameter is 25-28cm, and the normal value of the sacral pubic external diameter is 18-20cm. When the input module sends the measurement data to the evaluation control unit, the evaluation control unit compares the received measurement data with the corresponding standard value, sends the evaluation result to the display module for display, and prints it through the printing module.

[0036] The reading control unit is arranged on the measuring instrument through the reading dial 2 to assist the operator to read the reading quickly, such as Figure 3 As shown, the reading control unit includes a trigger 3, a timing module, a control module, and a voice module; wherein the trigger 3 is electrically connected to the timing module, and the timing module, the voice module, and the control module are electrically connected. Figure 4 As shown, the reading dial 2 is stuck on the scale 12 of the measuring device, and the reading dial 2 is provided with scale marks 21 corresponding to the scale lines on the scale 12. Specifically, the scale marks 21 are transparent strip grooves, and a lamp bead is provided under each transparent strip groove. The lamp bead is electrically connected to the control module, and the specific lamp bead can be an LED lamp; in actual use, the transparent strip groove can only correspond to the integer scale lines on the scale 12. This embodiment is conducive to assisting the operator to read the reading quickly and accurately by setting a reading control unit; as shown in FIG. Figure 6 As shown, when the measuring foot 11 sets the two measuring points, the pointer 13 stays on a certain scale, and the lamp bead on the corresponding scale lights up, thereby serving as a reminder. For operators who frequently measure multiple pregnant women for a long time, the auxiliary role of the lamp bead can reduce reading fatigue, thereby improving the efficiency and accuracy of reading.

[0037] The trigger 3 includes a metal conductive sheet 31 and a metal trigger sheet 32. Figure 5 As shown, the metal conductive sheet 31 and the metal trigger sheet 32 ​​are both provided with contacts 312. When the metal conductive sheet 31 and the contacts 312 on the metal trigger sheet 32 ​​are in contact, a closed circuit is formed (the trigger 3 in this application contacts to achieve circuit closure using the existing switch closing principle); Figure 4 As shown, the metal conductive sheet 31 is arranged along the scale mark 21 on the reading dial 2. The specific arrangement position of the metal conductive sheet 31 in this embodiment is as follows: Figure 4As shown, the metal conductive sheet 31 is located in front of each scale mark 21, and the metal trigger sheet 32 ​​is set on the pointer 13 of the measuring instrument. When the pointer 13 moves, the metal trigger sheet 32 ​​at the front end of the pointer 13 contacts the metal conductive sheet 31 to form a closed circuit, thereby turning on the timing module; in other embodiments other than this embodiment, when the metal trigger sheet 32 ​​on the pointer 13 contacts the metal conductive sheet 31 in front of any scale mark 21, a closed circuit is formed, which can make the lamp bead at the corresponding scale mark 21 light up; and the current generated by the closed circuit in the present application is a human safety current of 10mA or less, wherein in order to protect the trigger 3, a transparent cover for protection can also be set on the reading dial 2.

[0038] Specifically, when the measuring foot 11 is opened to start positioning measurement, the pointer 13 rotates on the dial 12, and the metal trigger sheet 32 ​​on the pointer 13 contacts the metal conductive sheet 31 and triggers the timing module to start timing. When the timing reaches the set time, the timing module sends a signal to the control module, and the control module controls the light bead at the position where the pointer 13 stops to light up, and turns on the voice module. After the voice module is turned on, it serves as an input module. The voice module can simplify the subsequent recording process. When the light bead is on and the voice module is turned on, the operator can quickly read the measured data. The voice module also collects the data read by the operator and transmits the collected data to the evaluation control unit. When the measurement is completed, the measurement data is recorded at the same time, and there is no need to enter the measurement data into the computer system separately, which makes the operation simpler and more convenient; and the voice module is only turned on when the light bead is on, which can reduce the interference and influence of noise.

[0039] In this embodiment, by setting a timing module, the corresponding lamp bead will light up only when the pointer 13 stays at a certain position, which can further improve the accuracy of measurement and reduce the probability of misreading; when the metal trigger sheet 32 ​​on the pointer 13 contacts the metal conductive sheet 31, the timing module starts timing, and the set time can be set to 2-5s according to the proficiency of different personnel. For example, for a skilled operator, the positioning of the measuring foot 11 can be completed quickly, and the set time can be 2s. When 2s is reached, the timing module sends a signal to the control module, and the control module controls the lamp bead at the position where the pointer 13 stays to light up; for an unskilled operator, the set timing time can be 4s, 5s, etc.

[0044] After the measurement is completed, the measuring foot 11 of the measuring device is extended from the opening of the bag taking channel 51 to the bottom. When it touches the detector 511 at the bottom, it indicates that the position is properly placed. After the detector 511 is triggered, the signal is sent to the controller. The controller controls the second indicator light 42 located in the disinfection area 6 to light up, instructing the medical staff to disinfect their hands. When the hands are disinfected, the controller controls the first indicator light 41 to light up, instructing the medical staff to take out the measuring device; and when the first indicator light 41 is on, the controller simultaneously controls the negative pressure The suction cup 52 is opened, and the negative pressure suction cup 52 absorbs and fixes the sterile film, so that the measuring foot 11 can be taken out from the bag taking channel 51, and the sterile film remains in the bag taking channel 51; when the measuring device is taken out, the negative pressure suction cup 52 is closed, and the sterile film falls from the vertical channel 53 to the recovery box 54 for collection; wherein, the negative pressure suction cup 52 is fixed by the telescopic part 521.
