Description

Technical Field

[0001] The invention relates to the technical field of delivery instruments, and in particular to a gynecological and obstetric fetal position auxiliary adjustment device. Background Art

[0002] Under normal circumstances, the fetus in the pregnant woman's body is head down and can pass through the birth canal smoothly to complete delivery. However, when the fetus is in an abnormal position, such as breech position or transverse position, the fetal head is not at the entrance of the pelvis and it is difficult to pass through the birth canal, which increases the difficulty of delivery and takes longer to pass through the birth canal smoothly. Not only does it increase the pain of delivery, but an abnormal fetal position may also cause the fetus's umbilical cord to be compressed, making it impossible for the fetus to get enough oxygen supply, and then there is a risk of fetal asphyxia.

[0003] Since natural childbirth is beneficial to the health of mother and baby, obstetrics departments in hospitals usually recommend natural childbirth. In the prior art, external breech version is a method of adjusting the fetal position through manual intervention, which can make the fetus originally in breech position (i.e., the fetus's buttocks facing down and head facing up) rotate clockwise or counterclockwise, and finally turn to head position (i.e., the fetus's head facing down), which can significantly improve the success rate of vaginal delivery.

[0004] However, external gluteal inversion has the disadvantages of being difficult to operate and requiring high operation requirements. In actual operation, it is difficult to succeed due to the limitations of the fetus, pelvic position, amniotic fluid and other conditions, especially when the breech position is stuck in the pelvis. External pushing and other methods can be used to assist the fetus in the pelvis to leave, so as to reduce the difficulty of external gluteal inversion. Therefore, the present invention provides a gynecological fetal position auxiliary adjustment device suitable for the narrow environment in the vagina, which has the characteristics of flexible adjustment, and can lift the fetus out of the pelvis as a whole, reducing the difficulty of external gluteal inversion. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a gynecological and obstetric fetal position auxiliary adjustment device, which has the characteristics of flexible adjustment, so as to lift the fetus out of the pelvis as a whole and reduce the difficulty of external hip inversion.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an auxiliary adjustment device for the fetal position in obstetrics and gynecology, comprising a support rod and a lifting mechanism for raising the height of the buttocks of a pregnant woman, an expansion layer symmetrically arranged with the support rod as the center is provided on the top of the support rod, the expansion layer comprises a support layer and a plurality of air bags symmetrically arranged with the expansion layer as the center, and the air bags are fixedly connected to the support layer;

[0007] The airbags are all connected with an air tube, which is located inside the support rod. A pull rope is connected to the side of the support layer away from the support rod. A slider is connected to the end of the pull rope away from the support layer. The slider is located inside the support rod, and the slider and the support rod are slidably matched.

[0008] One end of the slider away from the pull rope is fixedly connected with a push rod, and the push rod is slidably matched with the support rod;

[0009] When the slider is at the lowest point, the expansion layer is located inside the support rod; when the slider is at the highest point, the expansion layer is located outside the support rod.

[0010] The technical principle of the above scheme is as follows: First, the lifting mechanism is used to raise the buttocks of the pregnant woman to reduce the possible adhesion between the fetal membrane and the pelvis, and a certain gap space is provided to place the support rod. The expansion layer is sent into the vagina through the support rod so that the expansion layer is at the junction of the pelvis. Then, the air bag is inflated by delivering gas through the trachea to support the fetal mantle, so as to drive the telescopic expansion layer to extend. The push rod is used to drive the expansion layer to retract into the support rod through the pull rope, so as to facilitate the subsequent removal of the entire device.

[0011] The above scheme has the following beneficial effects:

[0012] 1. In this solution, when the airbag gradually expands, the bent airbag becomes vertical, thereby driving the airbag located inside the support rod to extend, so as to move the slider through the pull rope, so that the slider can be moved later by the push rod, and the expansion layer is retracted into the support rod by the pull rope, so that the expansion process of the airbag can be limited by the push rod, which is convenient for flexible adjustment and control.

[0013] 2. In this solution, during the use of the device, since the expansion layer is inside the vagina, it is not convenient to determine the expansion of the expansion layer. The expansion and contraction of the expansion layer can be determined by sliding the slider, thereby providing a basis for doctors to perform resetting and other operations.

[0014] 3. This solution utilizes the cooperation of the lifting mechanism and the expansion layer to form an overall support for the fetal membrane, which has a supporting and stabilizing effect and facilitates the subsequent adjustment of the fetal position.

[0015] Furthermore, a rotating block is provided between the airbag and the support rod, the two sides of the rotating block are rotatably matched with the support rod, a cavity is opened at the center of the rotating block, the pull rope is located in the cavity, and the support layer is fixedly connected to the upper and lower sides of the rotating block;

[0016] A concave arc block is arranged between adjacent rotating blocks, and the arc block is fixedly connected to the top of the supporting block.

[0017] Beneficial effect: The arc block is used to shield the rotating block, so as to reduce the damaging stimulation of the rotating block on the surrounding tissue during the deep insertion of the support rod, so as to facilitate the deep placement of the support block.

[0018] Furthermore, one end of the support layer away from the support rod is fixedly connected to a closing block, the closing block is located between adjacent support layers, and one end of the pull rope away from the support rod is fixedly connected to the closing block.

[0019] Beneficial effect: The support layer is connected to form a whole through the closing block, which limits the change trajectory during the expansion of the airbag, so as to improve the stability of the expansion layer during the support process.

[0020] Furthermore, a plurality of transparent layers are fixedly connected to the support rod, and an LED light is fixedly connected to the sliding block.

[0021] Beneficial effect: The transparent layer is illuminated by the LED light on the slider to facilitate confirmation of the moving position of the slider, thereby providing a basis for the doctor's subsequent operations and ensuring safety during the operation.

[0022] Furthermore, a control panel is provided in the support rod, the control panel is located in the slider, the control panel is electrically connected to an air pressure sensor, the air pressure sensor is located in the airbag, and the air pressure sensor is used to measure real-time air pressure data in the expansion layer and send the real-time air pressure data to the control panel;

[0023] The control panel is used to compare the real-time air pressure data with the set standard value. If the real-time air pressure data is greater than the standard value, a flashing command is issued to the LED light; if the real-time air pressure data is less than the standard value, a maintenance command is issued to the LED light.

[0024] Beneficial effect: The air pressure sensor in the airbag is used to monitor the air pressure data in real time to determine whether the airbag is currently inflated, and then determine the support condition of the expansion layer, providing a basis for subsequent expansion layer recovery operations and continuous gas injection operations, so as to improve safety during operation.

[0025] Furthermore, the air pipe is located inside the support rod, the air pipe is located on both sides of the slider, the air pipes corresponding to the air bags are respectively connected with a card block, the card block is slidably matched with the support rod, and the card blocks are arranged in order from top to bottom according to the distance of the air bag away from the support rod;

[0026] A magnet block is fixedly connected to one side of the slider close to the support rod, and a spring is slidably matched outside the block, one end of the spring is fixedly connected to the support rod, and the other end of the spring is fixedly connected to the side of the block away from the air pipe;

[0027] When the card block is in a normal state, the card block and the trachea are against each other; when the card block and the magnet block are on the same horizontal line, the card block is separated from the trachea.

[0028] Beneficial effect: During the sliding of the slider, the magnet on the slider adsorbs the card block to keep the current airway unobstructed and other airways closed, thereby achieving continuous deformation of each expansion layer.

[0029] Furthermore, the lifting mechanism includes a lifting bag and an auxiliary tube, and the push rod is connected with a connecting tube, and the connecting tube is connected with the trachea;

[0030] The auxiliary tube is located between the lifting bag and the connecting tube. A one-way valve and a flow limiting valve are connected in the auxiliary tube. The one-way valve can only allow the air in the lifting bag to flow into the connecting tube.

[0031] Beneficial effects: The lifting bag can lift the buttocks of pregnant women to reduce the possible adhesion between the fetal membrane and the pelvis. When the buttocks of pregnant women continue to apply pressure to the lifting bag, the gas inside the lifting bag is gradually transported to the connecting tube, so that the height of the lifting bag slowly decreases, so that the pregnant woman can lie flat later.

[0032] Furthermore, a moving block is provided at the connection between the connecting pipe and the air pipe, the moving block is slidably matched with the push rod, the left and right sides of the moving block are connected with docking tubes, the air pipe is fixedly connected to the docking tubes, the docking tubes are slidably matched with the connecting pipe, and several rubber layers for covering the connecting pipes are provided between the docking tubes and the connecting pipes.

[0033] Beneficial effect: The connecting function of the moving block is utilized to ensure that during the sliding process of the push rod and the support rod, the moving block drives the butt joint tube to slide on the connecting tube to maintain the connection between the air pipe and the connecting tube. During the sliding process of the butt joint tube on the connecting tube, the sealing effect of the rubber layer is utilized to improve the sealing of the connecting tube.

[0034] Furthermore, spray pipes for spraying lubricating liquid are provided on both sides of the rotating block, the spray pipes are fixedly connected to the support rod, and one end of the spray pipe away from the rotating block is located in the pushing rod.

[0035] Beneficial effects: The lubricating liquid is sprayed through the spray tube to lubricate the surface of the airbag to reduce the friction between the airbag and the fetal membrane or the surrounding tissue of the pregnant woman during contact, so as to facilitate the smooth extension and recovery of the expansion layer, thereby reducing possible damage to the expansion layer during support and improving the safety of the fetus.

[0036] Furthermore, it also includes an auxiliary support mechanism, which includes a support bag bonded to the pull rope, a branch pipe is connected between the support bag and the connecting pipe, and a solenoid valve is connected to the branch pipe. The pull rope is provided with a plurality of rollers for converting the movement direction of the pull rope, and the rollers are respectively located on the closing block and the side of the rotating block away from the airbag;

[0037] A roller is also sleeved on the end of the pull rope away from the closing block, and the roller is fixedly connected to the slider; the rollers are symmetrically arranged with the slider as the center, and a driving member is provided between adjacent rollers, and a gear set is meshed between the output shaft of the driving member and the rollers; the driving member and the solenoid valve are electrically connected to the control panel.

[0038] Beneficial effect: The driving part utilizes the gear set to drive the rollers on both sides to rotate in opposite directions. The rollers rotating in opposite directions drive the pull rope to move. The pull rope is transformed through the roller to continuously drive the support bag on the pull rope into the expansion layer. The support bag is expanded by opening the solenoid valve to support the adjacent support layer, thereby improving the stability of the airbag on the support layer.

[0057] A number of transparent layers 13 are also clamped on the support rod 1, and an LED lamp (not shown in the figure) is fixedly connected to the slider 4; a control panel (not shown in the figure) is arranged inside the support rod 1, the control panel is located inside the slider 4, the control panel is electrically connected to an air pressure sensor, the air pressure sensor is located inside the airbag 32, the air pressure sensor is used to measure the real-time air pressure data in the expansion layer 3, and send the real-time air pressure data to the control panel; the control panel is used to compare the real-time air pressure data with the set standard value, if the real-time air pressure data is greater than the standard value, a flashing command is issued to the LED lamp; if the real-time air pressure data is less than the standard value, a maintenance command is issued to the LED lamp.

[0058] The air pipe 34 is located inside the support rod 1, and the air pipe 34 is located on both sides of the slider 4. The air pipes 34 corresponding to each airbag 32 are respectively connected with a block 6, which is slidably matched with the support rod 1, and the blocks 6 are arranged in sequence from top to bottom according to the distance of the airbag 32 away from the support rod 1; a magnet block 43 is clamped on the side of the slider 4 close to the support rod 1, and a spring 61 is slidably matched on the outside of the block 6, one end of the spring 61 is clamped on the support rod 1, and the other end of the spring 61 is clamped on the side of the block 6 away from the air pipe 34; when the block 6 is in normal state, the block 6 is against the air pipe 34; when the block 6 and the magnet block 43 are on the same horizontal line, the block 6 is separated from the air pipe 34.

[0059] The specific implementation process is as follows: First, place the pregnant woman's buttocks on the lifting bag 2, slowly inflate the lifting bag 2 to lift the pregnant woman's buttocks, so as to reduce the possible adhesion between the fetal membrane and the pelvis, and provide a certain gap space for placing the support rod 1. As the pregnant woman's buttocks continue to apply pressure to the lifting bag 2, the gas inside the lifting bag 2 is gradually transported to the connecting tube 42, so that the height of the lifting bag 2 slowly decreases, so that the pregnant woman can lie flat later, and the gas transport of the expansion layer 3 is supplemented at the same time.

[0060] After the pregnant woman's buttocks are lifted, the expansion layer 3 and the support rod 1 are disinfected, and then the expansion layer 3 is sent into the vagina through the support rod 1, so that the expansion layer 3 is at the junction of the pelvis. The air tube 34 is used to deliver gas to expand the air bag 32 to support the fetal mantle, so as to drive the telescopic expansion layer 3 to extend. First, the air pressure sensor in the air bag 32 is used to monitor the real-time air pressure data to determine whether the air bag 32 is currently in a filled state, and then determine the support status of the expansion layer 3, so as to provide a basis for the subsequent recovery of the expansion layer 3 and the continuous gas injection operation, so as to improve the safety during operation.

[0061] During the sliding process of the slider 4, the movement distance of the slider 4 changes due to the expansion of the airbag 32 through the pull rope 52, so that the magnet block 43 on the slider 4 adsorbs the card block 6 to keep the current air tube 34 unblocked and the air tubes 34 corresponding to other airbags 32 closed, so as to automatically adjust the connection of the air tube 34 according to the change of the airbag 32, so as to achieve the continuous deformation of each expansion layer 3, so as to keep the airbag 32 on the expansion layer 3 for continuous inflation and deflation. Thus, the bent airbag 32 is changed to a vertical state through continuous gas injection, and then the airbag 32 located inside the support rod 1 is extended, so as to drive the slider 4 to move through the pull rope 52. When the expansion layer 3 is driven to retract to the inside of the support rod 1 through the pull rope 52, the slider 4 is driven by the push rod to pull the closing block 33 to limit the expansion process of the airbag 32, so as to facilitate flexible adjustment and control.

[0062] Embodiment 2:

[0063] The difference from Example 1 is that a moving block (not shown in the figure) is provided at the connection between the connecting tube 42 and the air pipe 34, the moving block is slidably matched with the push rod 41, the left and right sides of the moving block are connected with docking tubes (not shown in the figure), the air pipe 34 is fixedly connected to the docking tubes, the docking tubes are slidably matched with the connecting tube 42, and a number of rubber layers for covering the connecting tube 42 are provided between the docking tubes and the connecting tube 42.

During the sliding of the connecting tube on the connecting tube 42, the sealing function of the rubber layer is utilized to improve the sealing of the connecting tube 42.

[0065] Embodiment 3:

[0066] The difference from Example 2 is that both sides of the rotating block 11 are provided with a spray pipe 7 for spraying lubricating liquid, the spray pipe 7 is clamped with the support rod 1, and the end of the spray pipe 7 away from the rotating block 11 is located in the push rod 41.

[0067] The specific implementation process is as follows: the lubricating liquid is sprayed through the spray tube 7 to lubricate the surface of the airbag 32 to reduce the friction between the airbag 32 and the fetal membrane or the surrounding tissue of the pregnant woman during contact, so as to facilitate the smooth extension and recovery of the expansion layer 3, thereby reducing the damage that may occur during the support process of the expansion layer 3 and improving the safety of the fetus.

[0068] Embodiment 4:

[0071] The specific implementation process is as follows: when the airbag 32 is fully inflated, the driving part is started, and the driving part uses the gear set to drive the rollers 51 on both sides to rotate in opposite directions. The rollers 51 rotating in opposite directions drive the pull rope 52 to move, and the pull rope 52 is transformed by the roller 54 to continuously drive the support bag 53 on the pull rope 52 into the expansion layer 3. The support bag 53 is inflated by opening the solenoid valve to support the adjacent support layer 31, thereby improving the stability of the airbag 32 on the support layer 31.
