Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a novel 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 instrument has been fully 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 bladder, 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 requirement for sealing, 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 the internal inflation, simply inserting the seal is prone to leakage and falling off, which is unsafe.

[0005] At the same time, when medical staff put 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 prior art, medical staff can only rotate the airbag, the airbag handle, and the hose as a whole, which not only has a large range of motion, but also easily causes the hose to fold, thereby interfering with gas circulation.

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, which is convenient for inserting the airbag handle 15 into the hose 14 for connection.

[0027] In order to prevent the moving ring 23 from getting stuck during horizontal movement, the following features are also specifically provided: The transmission unit includes four gears 25 and an annular rack 26. The four gears 25 are respectively fixedly sleeved on the outer walls of the circumference of the four screw guide sleeves 24. The annular rack 26 is rotatably arranged on the inner wall of the circumference of the annular transmission cavity. The annular rack 26 and the four gears 25 are all meshed and installed.

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 to drive the other three gears 25 and the screw guide sleeve 24 to rotate synchronously, thereby preventing the screw guide sleeve 24 from rotating asynchronously and causing the moving ring 23 to get stuck when moving.

[0028] In order to drive the airbag handle 15 to move through the moving ring 23, the following features are also specifically provided: The clamping assembly includes four clamping blocks 35, and an annular moving cavity is opened in the moving ring 23. Four arc plates 30 are slidably arranged in the annular moving cavity. Specifically, the arc plate 30 is designed as a quarter ring. The four arc plates 30 can be combined into a ring. Every two adjacent arc plates 30 are connected by an extrusion unit. 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. The arc slide bar 31 is slidably arranged in the arc extrusion groove.

The four The outer walls of the peripheral sides of the arc plates 30 are each provided with a compression unit, the inner walls of the peripheral sides of the annular movable cavity are provided with four sliding holes, and the four clamping blocks 35 are respectively slidably arranged in the four sliding holes. The sides of the four clamping blocks 35 are respectively fixedly connected to the inner walls of the peripheral sides of the four arc plates 30, and the outer walls of the peripheral sides of the airbag handle 15 are 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, they 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 is convenient for realizing the connection operation.

[0029] In order to disassemble the airbag handle 15, the following features are also specifically provided: The compression unit includes four compression springs 34. The circumferential 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. The ends of three limiting shafts 32 are fixedly arranged on the circumferential 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 pulling plate 33. The four compression springs 34 are respectively sleeved on the circumferential 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 pulling plate 33, and then the arc-shaped sliding 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 the multiple clamping blocks 35 and the multiple clamping grooves 36.

[0030] In order to limit the position of the annular rotating plate 22, the following features are also specifically provided: The extrusion limit assembly includes a rectangular slider 39, and a plurality of finger placement grooves 37 and a slide groove 38 are provided on the peripheral outer wall of the connecting sleeve 17. The slide groove 38 is connected to one of the finger placement grooves 37. The rectangular slider 39 is slidably arranged in the slide groove 38 through a reset unit. The reset unit includes a guide shaft 40, one end of which is fixedly mounted on the side inner wall of the slide groove 38. The sliding sleeve of the rectangular slider 39 is connected to the guide shaft 40. A reset spring 41 is sleeved on the peripheral outer wall of the guide shaft 40. The two sides of the reset spring 41 are respectively connected to the side inner walls of the rectangular slider 39 and the slide groove 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 compatible with the square extrusion rod 42 is provided on the side inner wall of the slide groove 38. Two telescopic shafts 44 are fixedly provided on the bottom inner wall of the slide groove 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, so that under the connecting action of the connecting rod 36, the rectangular slider 39, the square extrusion rod 42, and the friction pad 43 are squeezed, 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 it is necessary to rotate the airbag 16, by loosening the pressing plate 45, the rectangular sea mouth 39 and the square extrusion rod 42 can be 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 a synchronous rotation function.

[0031] The working principle of the 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.

[0032] When it is necessary to connect the airbag handle 15 and the hose 14, 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 achieve the clamping and fixing function.

[0033] 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 threads, drive the movable ring 23 to move synchronously in 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.

[0034] 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, so that the rectangular slider 39 is squeezed under the connection of the connecting rod 46, so that the square squeezing rod 42 and the friction pad 43 are synchronously moved toward the annular rotating plate 22, and the annular rotating plate 22 is squeezed to limit it and prevent it from rotating at will. When it is necessary to rotate the airbag 16, first release the index finger to release the pressing plate 45, and then re-engage the index finger. 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 moving 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 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.

[0035] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
