Fully Automatic Bionic Midwifery Instrument with Adaptive Altitude

Abstract

The present invention relates to the field of medical devices, and more specifically to a novel fully automatic bionic obstetric instrument with adaptive altitude. The instrument comprises an instrument body, an airbag handle, an airbag, an automatic sensing inflation mechanism, and a pipe connection mechanism. The automatic sensing inflation mechanism not only automatically inflates the airbag so that it can always be kept at a set threshold pressure under different altitude conditions, making it easy to adapt to different altitude conditions, but also detects the airbag pressure through an internal pressure sensor and automatically adjusts the internal pressure of the airbag. The pipe connection mechanism allows the airbag handle to be quickly fixed, providing strong stability. The provision of a sealing gasket and a sealing groove improves the sealing performance after connection, preventing it from falling off or leaking. By rotating only the airbag handle and airbag without rotating the hose, not only does the hose avoid folding, ensuring rapid gas circulation, but the operation range is also reduced, avoiding harm to pregnant women.

Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a fully automatic bionic obstetric instrument capable of self-adapting to altitude. Background Art

[0002] The fully automatic bionic midwifery instrument is a medical device designed specifically for full-term pregnant women. It uses bionic technology to simulate the natural delivery process and effectively dilates the cervix and vagina through non-drug means, thereby shortening the delivery process, alleviating maternal pain, and reducing the rate of perineal lacerations.

[0003] As a medical device that can shorten the labor process and help pregnant women relieve pain, the fully automatic bionic midwifery device has been widely promoted. However, due to different altitudes in different regions, the atmospheric pressure will be affected, thereby affecting the inflation rate of the internal air bag and air sac, affecting its use.

[0004] When the current fully automatic bionic midwifery instrument is in use, medical staff connect the airbag handle and the hose. Due to the high sealing requirements, medical staff need to apply greater force to insert the airbag handle into the hose for fixation. However, most medical staff in obstetrics and gynecology are women with less strength, and the connection operation is somewhat difficult. In actual use, due to internal inflation, simply inserting the seal is prone to leakage and falling off, which is somewhat unsafe.

[0005] At the same time, when medical staff place the airbag and the airbag handle into the vagina for assisting delivery, they need to cooperate with certain rotation operations so as to reduce the pain caused to the pregnant woman when adjusting the position. In the existing technology, medical staff can only rotate the airbag, the airbag handle, and the hose as a whole when rotating. Not only is the movement amplitude large, but it is also easy to cause the hose to fold, which interferes with gas circulation. Summary of the Invention

[0040] In order to improve the sealing performance when the hose 14 and the airbag handle 15 are connected, the following features are specifically provided:

[0041] The pipeline connection mechanism also includes a sealing gasket 18. One end of the connecting sleeve 17 extends to the outside of the hose 14. The sealing gasket 18 is fixedly arranged on the inner wall of the connecting sleeve 17. The outer wall of the airbag handle 15 is provided with an annular sealing groove 19. The sealing gasket 18 is adapted to the annular sealing groove 19. Specifically, when the airbag handle 15 is inserted into the hose 14, the sealing gasket 18 is provided on the inner wall of the connecting sleeve 17, which can cooperate with the annular sealing groove 19 provided on the outer wall of the airbag handle 15 to improve the sealing performance and further prevent gas leakage.

By opening an annular limit groove and rotatably setting the T-shaped limit ring 22 in the annular limit groove, it can be limited without affecting its rotation to prevent it from falling off or offset, thereby effectively limiting the annular rotating plate 22.

[0044] In order to drive the moving ring 23 to achieve horizontal movement, the following features are specifically provided:

[0045] The fastening assembly includes four screw guide sleeves 24, an annular transmission cavity is opened in the annular rotating plate 22, and four rotating holes are opened on the inner wall of the end of the annular transmission cavity. The four screw guide sleeves 24 are rotatably installed in the four rotating holes respectively, and the ends of the four screw guide sleeves 24 are rotatably installed on the inner wall of the end of the annular transmission cavity. The four screw guide sleeves 24 are connected by a transmission unit. The four screw guide sleeves 24 are all threaded with screws 29, and the ends of the four screws 29 are fixedly connected to the end of the moving ring 23. By rotating the four screw guide sleeves 24, the four screws 29 can be driven to achieve synchronous horizontal movement under the action of the threads, thereby driving the moving ring 23 and the airbag handle 15 to move synchronously, making it convenient to insert the airbag handle 15 into the hose 14 for connection.

[0046] In order to prevent the movable ring 23 from getting stuck during horizontal movement, the following features are also provided:

[0047] The transmission unit includes four gears 25 and an annular rack 26. The four gears 25 are fixedly sleeved on the outer walls of the four screw guide sleeves 24. The annular rack 26 is rotatably set on the inner wall of the annular transmission cavity. The annular rack 26 and the four gears 25 are all meshed and installed. A motor groove is opened on the inner wall of the end of the annular transmission cavity. A drive motor 27 is set in the motor groove.

Specifically, the control switch 28 and the drive motor 27 are connected through a PLC controller. By pressing the control switch 28, the drive motor 27 is driven to work, thereby driving one of the screw guide sleeves 24 and the gear 25 to rotate. When the gear 25 rotates, it engages with the annular rack 26, and drives the other three gears 25 and the screw guide sleeve 24 to rotate synchronously, preventing the screw guide sleeve 24 from rotating asynchronously, causing the moving ring 23 to get stuck during movement.

[0048] In order to drive the airbag handle 15 to move through the movable ring 23, the following features are also provided:

[0049] The clamping assembly includes four clamping blocks 35, an annular moving cavity is opened in the moving ring 23, and four arc plates 30 are slidably arranged in the annular moving cavity. Specifically, the arc plate 30 is a quarter ring design, and the four arc plates 30 can be combined into a ring. Every two adjacent arc plates 30 are connected by an extrusion unit, and the extrusion unit includes an arc slide bar 31 and an arc extrusion groove. The arc extrusion groove is opened on the side of one of the arc plates 30, and the arc slide bar 31 is slidably arranged in the arc extrusion groove. One side of the arc slide bar 31 is fixedly connected to the side of another arc plate 30. The outer walls of the circumference of each arc-shaped plate 30 are provided with a compression unit, the inner wall of the circumference of the annular movable cavity is provided with four sliding holes, and the four clamping blocks 35 are respectively slidably set in the four sliding holes. The sides of the four clamping blocks 35 are respectively fixedly connected to the inner walls of the circumference of the four arc-shaped plates 30, and the outer wall of the circumference of the airbag handle 15 is provided with four clamping grooves 36. The four clamping blocks 35 are respectively adapted to the four clamping grooves 36. Through the setting of the four clamping blocks 35, it can be clamped with the four clamping grooves 36, so that when the movable ring 23 moves, the airbag handle 15 is driven to move synchronously through the clamping action, which facilitates the connection operation.

[0050] In order to disassemble the airbag handle 15, the following features are specifically provided:

[0051] The compression unit includes four compression springs 34. The outer walls of the four arc-shaped plates 30 are all provided with circular grooves. The limiting shafts 32 are slidably installed in the four circular grooves, wherein the ends of three limiting shafts 32 are fixedly provided on the inner walls of the annular movable cavity, and the end of another limiting shaft 32 extends to the outside of the movable ring 23 and is provided with a pull plate 33. The four compression springs 34 are respectively sleeved on the outer walls of the four limiting shafts 32. When the airbag handle 15 needs to be disassembled, one of the limiting shafts 32 and the arc-shaped plate 30 is driven to move synchronously by pulling the pull plate 33, and then the arc-shaped slide rod 31 slides in the arc-shaped extrusion groove to squeeze the remaining arc-shaped plates 30, so that they move synchronously in the direction away from the axis, thereby releasing the clamping limit of multiple blocks 35 and multiple slots 36.

[0052] In order to limit the position of the annular rotating plate 22, the following features are specifically provided:

[0053] The extrusion limit assembly includes a rectangular slider 39, and a plurality of finger placement grooves 37 and slides 38 are provided on the peripheral outer wall of the connecting sleeve 17. The slide 38 is connected to one of the finger placement grooves 37, and the rectangular slider 39 is slidably set in the slide 38 through a reset unit. The reset unit includes a guide shaft 40, one end of the guide shaft 40 is fixedly mounted on the side inner wall of the slide 38, and the sliding sleeve of the rectangular slider 39 is connected to the guide shaft 40. A reset spring 41 is provided on the peripheral outer wall of the guide shaft 40, and the two sides of the reset spring 41 are respectively connected to the rectangular slider 39 and the side inner wall of the slide 38. A square extrusion rod 42 is fixedly provided on the side of the rectangular slider 39, and a friction pad 43 is provided on the side of the square extrusion rod 42. An avoidance hole adapted to the square extrusion rod 42 is provided on the side inner wall of the slide 38, and two telescopic shafts 44 are fixedly provided on the bottom inner wall of the slide 38. The ends of the two telescopic shafts 44 A pressing plate 45 is fixedly installed together, and a connecting rod 46 is rotatably installed on the side of the pressing plate 45. The other end of the connecting rod 46 is rotatably installed on the side of the rectangular slider 39. When holding the fixed sleeve 20, the index finger presses the pressing plate 45, thereby driving the rectangular slider 39, the square extrusion rod 42, and the friction pad 43 to be squeezed under the connection action of the connecting rod 36, thereby squeezing and limiting the annular rotating plate 22 to prevent the annular rotating plate 22 from rotating randomly during use and causing harm to pregnant women. When the airbag 16 needs to be rotated, by loosening the pressing plate 45, the rectangular sea mouth 39 and the square extrusion rod 42 can be driven to reset under the elastic action of the reset spring 41, thereby releasing the clamping of the annular rotating plate 22, and then the annular rotating plate 22 is rotated through the cooperation of the thumb and index finger, thereby driving the moving ring 23, the airbag handle 15, and the airbag 16 to achieve synchronous rotation function.

[0054] The working principle of this device is that before use, the atmospheric pressure is detected according to the external pressure sensor 6, so that the air pump 4 automatically inflates the air bag 2 according to the detected atmospheric pressure. When in different altitudes, the pressure of the air bag 2 will be automatically corrected so that the gas inside always maintains the set threshold. When it is necessary to inflate the air bag 16, the air inlet solenoid valve 10 is opened to inflate the air bag 16. During the inflation process, the pressure of the air bag 16 is detected by the internal pressure sensor 11, and the gas in the air bag 16 can be discharged through the exhaust solenoid valve 13, which is convenient for adjusting the pressure in the air bag 16. According to the cooperation of the external pressure sensor 6 and the internal pressure sensor 11, the inflation time and number of times are controlled, which is convenient for use in different altitudes.

[0055] When the airbag handle 15 and the hose 14 need to be connected, the medical staff inserts the airbag handle 15 into the movable ring 23 and squeezes the multiple blocks 35 through the tip of the airbag handle 15. At this time, under the sliding connection between the multiple arc-shaped slide rods 31 and the multiple arc-shaped extrusion grooves, the multiple arc-shaped plates 30 and the multiple blocks 35 move synchronously away from the axis and squeeze the compression spring 34. When the airbag handle 15 moves to a suitable position, the multiple blocks 35 drive the multiple arc-shaped plates 30 and the multiple blocks 35 to reset synchronously under the elastic action of the compression spring 34, so that the multiple blocks 35 and the multiple slots 36 can realize the clamping and fixing function.

[0056] Pressing the control switch 28 activates the drive motor 27, thereby driving one of the screw guide sleeves 24 to rotate. Under the meshing action of the four gears 25 and the annular rack 26, the other three screw guide sleeves 24 can be driven to rotate synchronously, so that the four screws 29, under the action of the thread, drive the movable ring 23 to move synchronously toward the direction close to the annular rotating plate 22, so that the end of the airbag handle 15 is inserted into the hose 14. Through the action of the sealing gasket 18 and the annular sealing groove 19, the sealing performance of the connection can be improved to prevent gas leakage.

[0057] During use, the medical staff holds the fixed sleeve 20 and squeezes the pressing plate 45 with the index finger to make it move toward the finger placement groove 37, thereby squeezing the rectangular slider 39 under the connection of the connecting rod 46, so that it drives the square squeezing rod 42 and the friction pad 43 to move synchronously toward the annular rotating plate 22, and squeezes the annular rotating plate 22, thereby limiting it and preventing it from rotating at will. When it is necessary to rotate the airbag 16, first release the index finger to release the pressure on the pressing plate 45, and then re-engage it. Under the elastic action of the positioning spring 41, the rectangular slider 39 and the square extrusion rod 42 are driven to reset, and the limit on the annular rotating plate 22 is released. Then, the annular rotating plate 22 is rotated to drive the movable ring 23, multiple blocks 35, the airbag handle 15, and the airbag 16 to realize the synchronous rotation function. It is easy to use and has a small operation range, which avoids causing severe pain to pregnant women during use. At the same time, by only rotating the airbag handle 15 and the airbag 16 without rotating the hose 14, the hose 14 is avoided from folding, thereby ensuring the rapid circulation of gas.

[0058] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
