Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a fetal head aspirator for assisting childbirth. Background Art

[0002] In the process of giving birth in obstetrics and gynecology, the delivery process is not always smooth. When the mother has weak uterine contractions, persistent transverse or posterior occipital position, etc., it will make natural delivery very difficult. At this time, the means of midwifery are particularly important and critical. At this time, fetal head vacuum suction is one of the important means to solve difficult delivery. By using the negative pressure generated by the suction device, the fetal head is adsorbed to assist the mother in delivering the fetus. It plays an important role in many cases of difficult delivery for pregnant women. The traditional fetal head vacuum consists of three parts: a suction head, a rubber catheter and a suction device. However, in actual use, the existing fetal head vacuum has some problems that need to be solved urgently, such as the fetal suction silicone head and the fetal head are easily slipped due to leakage, the uneven negative pressure during suction easily causes uneven force on the fetal head, and may cause damage to the fetal head. This improved midwifery fetal head vacuum is designed to address these problems and improve the safety and success rate of midwifery by optimizing the structural design. Summary of the Invention

[0003] The purpose of the present invention is to provide a fetal head suction device for assisting childbirth, so as to solve the problem in the above background technology that air leakage easily occurs during negative pressure adsorption, resulting in the separation of the fetal suction silicone head from the fetal head.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fetal head suction device for midwifery, comprising a traction rod with a hollow tubular design, and a fetal suction silicone head is mounted on the outer surface of one end of the traction rod, a scale line is fixedly provided on the outer surface of one side of the traction rod, and a number is laser-engraved on one side of the scale line, a low-negative pressure adsorption machine is placed on a table on one side of the traction rod, and a separation tank is mounted on the outer surface of one side of the low-negative pressure adsorption machine, and the separation tank is connected to the low-negative pressure adsorption machine, an edge strip is fixedly mounted on the outer surface of the fetal suction silicone head away from the traction rod, and the edge strip is located on the outside of the fetal suction silicone head, and the fetal suction silicone head is a bucket-shaped design, the material of the edge strip is slightly harder than that of the fetal suction silicone head, and the fetal suction silicone head and the edge strip are concentrically designed, and a thin edge is fixedly provided on the outer surface of one end of the edge strip, and the thin edge and the edge strip are concentrically designed.

[0005] Preferably, a snap-fitting groove is provided on the outer surface of one end of the traction rod close to the tire suction silicone head, and the snap-fitting groove is engaged with the outer surface of the tire suction silicone head. A threaded fastening mechanism is provided between the tire suction silicone head and the traction rod. Buffer gel blocks are evenly fixed on the inner side of the tire suction silicone head, and the buffer gel blocks are higher than the outer surface of the tire suction silicone head.

[0006] By adopting the above technical solution, the friction force of the tire suction silicone head after installation can be increased through the snap-fit ​​groove, so that the tire suction silicone head is not easily separated from the snap-fit ​​groove, and the chance of air leakage can be reduced. At the same time, the buffering gel block plays a buffering role, which can make the tire suction silicone head play a buffering role when adsorbing the fetal head, and further reduce the direct pressure of negative pressure adsorption, reduce the chance of damage to the fetal head, and improve the fit and stability of adsorption.

[0007] Preferably, the threaded fastening mechanism includes: an inlay block, which is fixedly mounted on one end of the traction rod close to the snap-fit ​​groove, and the snap-fit ​​groove is blocked by the inlay block, the outer surface of one end of the inlay block is evenly divided, and the inlay block and the snap-fit ​​groove are concentrically designed, a twisting block is threadedly mounted on the outer surface of the inlay block, the outer surface of the inlay block is tightly fitted with the outer surface of the tire suction silicone head, the twisting block is inclined, and a symmetrical through-hole is opened on the outer surface of one end of the twisting block.

[0008] By adopting the above technical solution, the twisting block is screwed into the interior of the fitting block, which will cause the fitting block to shrink and clamp the fetal silicone head. Combined with the use of the snap-fit ​​groove, the doctor can adsorb the fetal silicone head to the fetal head and guide it outward, reducing the chance of the fetal silicone head falling due to pulling force. At the same time, the twisting block on the outside further reduces the chance of damage to the fetal head.

[0009] Preferably, a thickened dividing strip is evenly fixedly installed on the inner side of the tire suction silicone head, and the thickened dividing strip is higher than the outer surface of the tire suction silicone head, and one end of the thickened dividing strip close to the edge strip is inclined.

[0010] By adopting the above technical solution, the overall support of the fetal silicone suction head can be improved by thickening the separating strip. At the same time, the negative pressure can be applied more evenly to the fetal head, reducing the risk of excessive local pressure caused by uneven air pressure due to a single airway. In addition, if there is a slight air leak in a certain local position of the fetal silicone suction head, other positions can still maintain a certain negative pressure, thereby maintaining the adsorption force on the fetal head and preventing the fetal silicone suction head from falling off and causing harm to the fetus.

[0011] Preferably, a rubber-coated spacer wire is fixedly installed inside the tire suction silicone head, and the rubber-coated spacer wire is designed in a M-shaped arc, and the rubber-coated spacer wire and the tire suction silicone head are concentrically designed, and a displacement detection mechanism is provided between the rubber-coated spacer wire and the traction rod.

[0012] By adopting the above technical solution, the head of the fetus can be shielded by the rubber-coated spacer wire, and the M-shaped arc design of the rubber-coated spacer wire makes the fetus's head more comfortable after being adsorbed.

[0013] Preferably, the displacement detection mechanism includes: a guide push rod, which is slidably installed inside the traction rod, and one end of the traction rod is inserted into the rubber-coated spacer wire, and a magnetic sensor is fixedly installed on the outer surface of the end of the traction rod away from the tire suction silicone head, and the magnetic sensor is fixed with a screw, and a strong magnetic block is fixedly installed on the end of the guide push rod close to the magnetic sensor, and the strong magnetic block and the traction rod are concentrically designed, the magnetic sensor is connected to the low-negative pressure adsorption machine, and a buzzer reminder is fixedly installed on the outer surface of the low-negative pressure adsorption machine.

[0014] By adopting the above technical solution, the rubber-coated spacer wire will be deformed after the fetal silicone head is adsorbed on the fetus's head. At this time, the rubber-coated spacer wire will push the guide push rod to slide inside the traction rod, so that the strong magnetic block can move and pass through the magnetic sensor. When the fetus's head completely blocks the air suction hole of the fetal silicone head, the low-negative pressure adsorption machine can stop working, and the fetal head will not block the air suction hole of the fetal silicone head and continue to pump air, which will cause damage to the fetal head due to excessive adsorption.

[0015] Preferably, a blocking rod is fixedly installed on one end of the traction rod away from the tire suction silicone head, and a shaft sleeve is mounted on the outer surface of the blocking rod. A movable tightening screw is threadedly mounted on the outer surface of one end of the shaft sleeve, and the outer surface of the movable tightening screw fits the outer surface of the blocking rod.

[0016] By adopting the above technical solution, the position of the sleeve on the clamping rod can be adjusted, so that the position of the clamping handle can be adjusted, which is convenient for medical staff to use.

[0017] Preferably, a tooth block is fixedly installed on the outer surface of the sleeve, and a clamping handle is clamped and installed on the outer surface of the tooth block, and the outer surface of the clamping handle does not fit the outer surface of the sleeve, a thin iron sheet is fixedly installed between the clamping handles, and a side support arm is fixedly installed on the outer surface of the thin iron sheet, and the side support arm has the same parallelism as the clamping handle.

[0018] By adopting the above technical solution, the opening and closing of the snap-on handle will not be affected by the thin iron sheet, so that the angle between the snap-on handle and the shaft sleeve can be adjusted after opening, and the snap-on rod can be rotated to lock, which can prevent the snap-on handle from bouncing open, so that the rotation angle of the snap-on handle can be adjusted at will to facilitate the doctor's operation.

[0019] Preferably, a rubber handle is fixedly installed on the outer surface of the snap-on handle, and a snap-on rod is installed through the outer surface of the rubber handle, and the snap-on rod is rotatably connected to the snap-on handle on one side, the snap-on rod is snapped with the rubber handle, and the outer surface of the rubber handle is provided with anti-slip texture.

[0020] The rubber handle improves the comfort during lifting, and the anti-skid lines further improve the anti-skid performance and reduce the probability of operation failure.

[0021] Preferably, the traction rod is externally fixed with an anti-skid nozzle at one end close to the clamping block, the outer surface of the anti-skid nozzle is externally inserted with a steel wire hose, the steel wire hose is connected with the separation tank, the outer surface of the steel wire hose is externally sleeved with a rubber ring, the side surface of the rubber ring is externally fixed with a button, the button is connected with the low negative pressure suction machine, and the circuit of the button and the magnetic attraction sensor is bound with the steel wire hose.

[0022] The anti-skid nozzle improves the firmness during connection with the steel wire hose, the steel wire hose effectively reduces the resistance during gas flow, reduces the risk of blockage, ensures the smoothness of the suction process, has good flexibility and strength, facilitates the flexible adjustment of the position and angle of the medical staff during operation, prevents the blockage or damage of the steel wire hose due to bending and the like, and ensures the reliability of the entire suction system.

[0023] Compared with the prior art, the midwifery fetal head suction device has the following beneficial effects:

[0024] 1. After the fetal suction silica gel head is inserted into the body of the parturient woman and adheres to the head of the fetus, the outer surface of the edge strip will adhere to the birth canal of the parturient woman to form a relatively sealed space, which can effectively prevent air leakage during the suction process, enhance the stability during suction, maintain the shape of the fetal suction silica gel head through the edge strip, and make the fetal suction silica gel head adhere to the fetal head more tightly through the thin edge, effectively prevent air leakage due to inconsistent pulling force direction and operation direction during the suction process, enhance the stability of the fetal suction silica gel head during suction, and reduce the phenomenon that the fetal suction silica gel head is separated from the head of the fetus due to air leakage;

[0025] 2. When the fetal suction silica gel head is inserted into the inside of the buckling groove, the fetal suction silica gel head will adhere to the outer surface of the inlay block, the inlay block will be tightened and clamped to the fetal suction silica gel head after the screwing block is tightened, and the buckling groove is used in cooperation, so that the fetal suction silica gel head will not be separated due to pulling during guided movement, the fetal suction silica gel head can be conveniently installed, disassembled and replaced, and the connection strength between the fetal suction silica gel head and the traction rod can be improved.

[0026] 3. When the fetal suction silicone head is adsorbed to the head of the fetus, the encapsulated spacer silk will be deformed and push the guide top rod to move together with the strong magnetic block, so that when the head of the fetus blocks the air suction hole of the fetal suction silicone head, the strong magnetic block can pass through the magnetic suction sensor, so that the low negative pressure suction machine can immediately stop sucking air, and reduce the damage to the head of the fetus caused by excessive adsorption when the low negative pressure suction machine still works when the head of the fetus blocks the air suction hole of the fetal suction silicone head;

[0027] 4. By tightening and loosening the movable tightening screw, the position of the shaft sleeve on the clamping block rod can be adjusted flexibly, and the thin iron sheet can make the clamping handle open, so that the clamping handle can adjust the angle on the shaft sleeve, and then the clamping handle can be pinched to make the clamping handle can be clamped and fixed with the tooth block, so that the angle and position of the clamping handle on the clamping block rod can be adjusted flexibly, so that the doctor can use it more conveniently, and the efficiency of guiding operation on the fetus can be improved.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-10 The present invention provides a technical solution: a midwifery fetal head suction device, comprising a traction rod 1 with a hollow tubular design, and a fetal suction silicone head 2 is mounted on the outer surface of one end of the traction rod 1, a scale line 3 is fixedly provided on the outer surface of one side of the traction rod 1, and a number is laser-engraved on one side of the scale line 3, a low-negative pressure adsorption machine 27 is placed on a table on one side of the traction rod 1, and a separation tank 28 is mounted on the outer surface of one side of the low-negative pressure adsorption machine 27, and the separation tank 28 is connected to the low-negative pressure adsorption machine 27, an edge strip 4 is fixedly mounted on the outer surface of the side of the fetal suction silicone head 2 away from the traction rod 1, and the edge strip 4 is located on the outside of the fetal suction silicone head 2, and the fetal suction silicone head 2 is a bucket-shaped design, the material of the edge strip 4 is slightly harder than that of the fetal suction silicone head 2, and the fetal suction silicone head 2 and the edge strip 4 are concentrically designed, and a thin edge 31 is fixedly provided on the outer surface of one end of the edge strip 4, and the thin edge 31 is concentrically designed with the edge strip 4.

[0041] The hollow design of the traction rod 1 allows gas to pass through for negative pressure extraction operation. At the same time, the use of the scale line 3 can intuitively check and know how far the fetus is from being delivered. The gas can be extracted by the low-negative pressure adsorption machine 27, and the extracted liquid can also be separated by the separation tank 28. The design of the edge strip 4 enables the fetal suction silicone head 2 to be adsorbed on the fetus's head. The edge strip 4 can better contact the mother's birth canal to form a relatively sealed space. At the same time, through the setting of the thin edge 31, the fetal suction silicone head 2 is more closely attached to the fetal head and the success rate of one-time fetal suction is improved. It can also effectively prevent air leakage caused by the inconsistency between the pulling force direction and the operation direction during the suction process, and enhance the stability of the fetal suction silicone head 2 during adsorption.

[0042] A snap-fitting groove 5 is provided on the outer surface of one end of the traction rod 1 close to the tire-absorbing silicone head 2, and the snap-fitting groove 5 is engaged with the outer surface of the tire-absorbing silicone head 2. A threaded fastening mechanism is provided between the tire-absorbing silicone head 2 and the traction rod 1. Buffer gel blocks 30 are evenly fixed on the inner side of the tire-absorbing silicone head 2, and the buffer gel blocks 30 are higher than the outer surface of the tire-absorbing silicone head 2.

[0043] The buffering gel block 30 can make the fetal suction silicone head 2 adsorbed on the fetus's head, which can effectively improve the cushioning performance, further reduce the direct pressure caused by negative pressure suction, reduce the chance of fetal head injury, and can adaptively deform to a certain extent according to the shape of the fetus's head, thereby improving the fit and stability of the fetal suction silicone head 2 during adsorption, and the engagement of the buckling groove 5 with the fetal suction silicone head 2 can further improve the sealing performance.

[0044] The threaded fastening mechanism includes: an inlay block 6, which is fixedly mounted on one end of the traction rod 1 close to the buckling groove 5, and the buckling groove 5 is blocked by the inlay block 6, the outer surface of one end of the inlay block 6 is evenly divided, and the inlay block 6 and the buckling groove 5 are concentrically designed, and a twisting block 7 is threadedly mounted on the outer surface of the inlay block 6, and the outer surface of the inlay block 6 is tightly fitted with the outer surface of the tire suction silicone head 2, the twisting block 7 is inclined, and a symmetrical through-hole is opened on the outer surface of one end of the twisting block 7.

[0045] When the tire-absorbing silicone head 2 is inserted into the inside of the snap-fit ​​groove 5, the outer surface of the tire-absorbing silicone head 2 will fit with the outer surface of the snap-fit ​​groove 5. At this time, tightening the twisting block 7 will tighten one end of the interlocking block 6. The tire-absorbing silicone head 2 is clamped by tightening the interlocking block 6. The inclined design and symmetrical through-holes of the twisting block 7 can facilitate disassembly and installation, and at the same time reduce the risk of physical injuries caused by scratches between the twisting block 7 and the pregnant woman. In conjunction with the snap-fit ​​groove 5, the tire-absorbing silicone head 2 will not be separated from the traction rod 1 due to tension during the process of negative pressure adsorption and guidance, thereby improving the firmness during use and facilitating the replacement of the tire-absorbing silicone head 2.

[0046] A thickened dividing strip 12 is evenly fixed on the inner side of the tire suction silicone head 2, and the thickened dividing strip 12 is higher than the outer surface of the tire suction silicone head 2. The end of the thickened dividing strip 12 close to the edge strip 4 is inclined.

[0047] By thickening the separating strip 12, the interior of the fetal suction silicone head 2 can be divided, so that the negative pressure can act more evenly on the fetal head, reducing the risk of excessive local pressure on the fetal head caused by uneven negative pressure in a single airway. In addition, when a slight air leak occurs in a certain part of the fetal suction silicone head 2, other airways can still maintain a certain negative pressure to maintain the adsorption force on the fetal head, thereby preventing the fetal suction silicone head 2 from directly loosening and causing harm to the fetus.

[0048] A rubber-coated spacer wire 8 is fixedly installed inside the tire suction silicone head 2, and the rubber-coated spacer wire 8 is a M-shaped arc design, and the rubber-coated spacer wire 8 and the tire suction silicone head 2 are concentrically designed. A displacement detection mechanism is provided between the rubber-coated spacer wire 8 and the traction rod 1.

[0049] The M-shaped arc design of the rubber-coated spacer wire 8 makes it more comfortable after it contacts and deforms with the fetal head, and can effectively reduce the probability of blockage between the fetal head and the air extraction hole of the fetal suction silicone head 2.

[0050] The displacement detection mechanism includes: a guide push rod 9, which is slidably installed inside the traction rod 1, and one end of the traction rod 1 is inserted into the rubber-coated spacer wire 8. A magnetic sensor 10 is fixedly installed on the outer surface of the end of the traction rod 1 away from the tire suction silicone head 2, and the magnetic sensor 10 is fixed with screws. A strong magnetic block 11 is fixedly installed on the end of the guide push rod 9 close to the magnetic sensor 10, and the strong magnetic block 11 and the traction rod 1 are concentrically designed. The magnetic sensor 10 is connected to the low negative pressure adsorption machine 27, and a buzzer reminder 29 is fixedly installed on the outer surface of the low negative pressure adsorption machine 27.

[0051] When the fetal silicone head 2 is adsorbed onto the fetal head, the rubber-coated spacer wire 8 will be deformed and push the guide push rod 9 to move, so that the guide push rod 9 can drive the strong magnetic block 11 to move together, so that the strong magnetic block 11 can automatically stop when the strong magnetic block 11 passes through the magnetic sensor 10, preventing the fetal head from blocking the exhaust hole of the fetal silicone head 2 and causing excessive negative pressure, reducing the damage to the fetal head caused by excessive negative pressure, and issuing an alarm through the buzzer reminder 29 when the fetal head blocks the exhaust hole of the fetal silicone head 2.

[0052] A blocking rod 13 is fixedly installed on the end of the traction rod 1 away from the tire suction silicone head 2, and a shaft sleeve 14 is clamped and installed on the outer surface of the blocking rod 13. A movable tightening screw 15 is threadedly installed on the outer surface of one end of the shaft sleeve 14, and the outer surface of the movable tightening screw 15 is in contact with the outer surface of the blocking rod 13.

[0053] By tightening and loosening the movable tightening screw 15, the position of the sleeve 14 on the clamping rod 13 can be adjusted, so that the distance between the clamping handle 17 and the fetal suction silicone head 2 can be adjusted, making it easier for doctors to use and improving the efficiency of fetal guidance.

[0054] A tooth block 16 is fixedly installed on the outer surface of the sleeve 14, and a clamping handle 17 is clamped and installed on the outer surface of the tooth block 16. The outer surface of the clamping handle 17 does not fit the outer surface of the sleeve 14. A thin iron sheet 18 is fixedly installed between the clamping handles 17, and a side support arm 22 is fixedly installed on the outer surface of the thin iron sheet 18. The side support arm 22 has the same parallelism as the clamping handle 17.

[0055] The clamping handles 17 can be separated from each other by the thin iron sheet 18, and then the angle of the clamping handle 17 can be rotated to adjust. After the clamping handle 17 is adjusted to a suitable angle, the clamping handle 17 can be gripped so that the clamping handle 17 can be engaged with the tooth block 16 to fix the angle of the clamping handle 17. The side support arm 22 can be used to improve the strength and flexibility during the gripping operation, so that the angle of the clamping handle 17 can be flexibly adjusted while being convenient to operate.

[0056] A rubber handle 19 is fixedly installed on the outer surface of the snap-on handle 17, and a snap-on rod 20 is installed through the outer surface of the rubber handle 19. The snap-on rod 20 is rotatably connected to the snap-on handle 17 on one side. The snap-on rod 20 is snapped with the rubber handle 19, and the outer surface of the rubber handle 19 is provided with anti-slip grooves 21.

[0057] The rubber handle 19 can improve the comfort during use, and the use of the snap-on rod 20 can limit the position of the snap-on handle 17 so that the snap-on handle 17 will not be opened casually and fall off. At the same time, the anti-slip pattern 21 can improve friction and reduce the chance of slipping during operation.

[0058] A non-slip mouth 23 is fixedly installed on the outer surface of one end of the traction rod 1 close to the blocking stick 13, and a steel wire hose 24 is fixed on the outer surface of the non-slip mouth 23, and the steel wire hose 24 is connected to the separation tank 28. A rubber ring 25 is sleeved on the outer surface of the steel wire hose 24, and a button 26 is fixedly installed on the side surface of the rubber ring 25, and the button 26 is connected to the low negative pressure adsorption machine 27. The button 26 and the line of the magnetic sensor 10 are bound to the steel wire hose 24.

[0059] The anti-slip mouth 23 can improve the firmness of the connection with the steel wire hose 24, and the rubber ring 25 can facilitate the installation of the button 26. While facilitating operation, the low negative pressure adsorption machine 27 can be deflated by pressing the button 26 to reduce the pressure during adsorption, thereby facilitating disassembly, installation and operation. At the same time, the steel wire hose 24 can effectively reduce the resistance during gas flow to reduce the risk of blockage and ensure smoothness during the vacuum process. The steel wire hose 24 has good flexibility and strength, which not only facilitates medical staff to flexibly adjust the position and angle of the suction device during operation, but also prevents pipeline blockage or damage caused by bending of the steel wire hose 24, thereby ensuring the reliability of the entire suction system.
