Description

Technical Field

[0001] The present application relates to the technical field of cesarean section, and in particular to a booster device for pushing up the fetal head during cesarean section. Background Art

[0002] Vaginal delivery is the normal way of delivering a fetus, also known as normal delivery clinically, which means that the fetus is delivered vaginally after full-term.

[0003] Some pregnant women are too old, whether the birth canal is normal, the size of the fetus, the fetal position, and the labor force during delivery, which will affect whether they can have a vaginal delivery. Therefore, some pregnant women may not be able to have a normal delivery during the vaginal trial delivery. At this time, they need to switch to a cesarean section during the process of guiding the trial delivery to the full dilation of the cervix. However, since the fetal head enters the pelvic position after labor, and the cervix is ​​fully dilated, the fetal head is deeply sunken in the pelvis. At this time, a cesarean section may be difficult to remove the head. If the head cannot be removed smoothly for a long time, it will directly lead to safety problems such as fetal asphyxia or laceration of the lower segment of the pregnant woman's uterus. Therefore, before or during a cesarean section, the fetal head in the pelvis needs to be pushed up to prevent the fetal head from getting stuck in the pelvis. The commonly used way to push the fetal head up is for the nurse to put his hand into the vagina under the operating table to push the fetal head back to the uterus, but this process cannot ensure absolute sterility and may cause the risk of retrograde infection in pregnant women; secondly, if the hand strength is uneven and the fetal head is soft, it is easy to squeeze the fetal head and cause the risk of skull fracture. Summary of the invention

[0004] The technical problem to be solved by the present application is to provide a pushing device for pushing up the fetal head during cesarean section surgery, which can ensure the sterility of the pushed fetal head and increase the stability during pushing.

[0009] The sides of the pressurizing chamber are respectively provided with communicating holes which are connected with the two sets of valve components.

[0010] In order to increase the area of ​​the booster airbag to wrap the fetal head and apply force evenly, in some embodiments, a suction cup is provided at the right end of the booster airbag, and a through hole is provided in the middle of the suction cup.

[0011] In order to fix the booster airbag and adjust its position on the hospital bed, in some embodiments, a booster plate is provided at the left end of the booster airbag.

DETAILED DESCRIPTION

[0024] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0025] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0026] The defects of the prior art, such as retrograde infection in pregnant women and uneven force in pushing up the fetal head. After careful analysis, the inventor found that the main reason for the above problems is that although the nurses' hands are disinfected, they will touch other objects during the delivery process, and there may be bacteria. If the fetal head is pushed up with bare hands, the bacteria may be brought into the vagina, causing bacteria to enter the uterus or other organs, resulting in retrograde infection; pushing up the fetal head requires stable force, and the strength of each finger of the palm may be different. The fetal head is relatively soft, and the contact area between the fingers and the fetal head is small. If the fingers contact the fetal head with too much force, it is easy to squeeze the fetal head and cause a skull fracture. Therefore, it may not be possible to ensure stable and uniform upward force with bare hands. Based on the above analysis, the inventor designed a booster device for pushing up the fetal head during cesarean section.

[0027] The present application provides an embodiment of a booster device for pushing up the fetal head during cesarean section. Figure 1-4 .

[0028] The device is arranged on a delivery bed 1, and comprises a boosting component 3 for pushing up the fetal head and a pressurizing component 4 for controlling the pushing out and contraction of the boosting component 3. The boosting component 3 and the pressurizing component 4 are connected by a pipeline, and the boosting component 3 is filled with gas.

[0029] The boosting component 3 includes a boosting airbag 31 that can wrap and push the fetal head. Gas is injected into the boosting airbag 31. A through hole 321 is opened at the right end of the boosting airbag 31. A soft negative pressure tube 12 is connected to the through hole 321. The negative pressure tube 12 is connected to a negative pressure gas source. After the boosting airbag 31 contacts the fetal head, the negative pressure tube 12 slightly forms a negative pressure to absorb the fetal head, thereby preventing the boosting airbag 31 from displacement.

[0030] The pressurizing component 4 includes a cylindrical pressurizing chamber 41, which is installed on one side of the bed body 1 through an existing clamp-type rigid fixing frame 9. A piston is arranged in the pressurizing chamber 41, one end of which is connected to a piston rod 42, which extends out of the pressurizing chamber 41, and a support rod is also arranged on the side of the pressurizing chamber 41, on which a lever 5 is hinged, and the right end of the lever 5 is hingedly connected to the piston rod 42. When the lever 5 is pressed down, the piston moves into the pressurizing chamber 41 to compress its internal space; when the lever 5 is lifted up, the piston moves in the opposite direction.

[0031] The side wall of the pressurizing chamber 41 is provided with a circle of sink grooves, in which a rotatable adjusting ring 43 is sleeved, and two sets of valve assemblies 8 are installed on the side wall of the adjusting ring 43. The valve assembly 8 includes two one-way valves, namely a first one-way valve 81 and a second one-way valve 82. The valve ports of the two one-way valves are arranged oppositely, such as Figure 4 As shown, the second one-way valve 82 is located on the side of the first one-way valve 81, the valve opening of the first one-way valve 81 faces left, and the valve opening of the second one-way valve 82 faces right;

[0032] In addition, the side grooves of the pressurizing chamber 41 are respectively provided with connecting holes 321 connected to the two sets of valve assemblies 8 .

[0033] The booster airbag 31 is an annular bellows structure, with a suction cup 32 at the right end of the booster airbag 31, a through hole 321 in the middle of the suction cup 32, and a negative pressure tube 12 and the back of the suction cup 32 are sealed and connected, and are connected to the through hole 321. Compared with a human hand, the suction cup 32 structure can increase the area of ​​the fetal head, which can improve the uniformity of force application, and fix the suction cup 32 on the fetal head through slight negative pressure suction, preventing the suction cup 32 and the booster airbag 31 from moving, so that the thrust is relatively concentrated.

[0034] The left end of the booster airbag 31 is provided with a booster plate 2, and the right end surface of the booster plate 2 is provided with a slot 21, and the left end surface of the booster airbag 31 is connected with a plastic fixing plate 34, and the fixing plate 34 can be inserted into the slot 21 of the booster plate 2 from top to bottom. The fixing plate 34 and the slot 21 are preferably transitionally matched to facilitate disassembly. A through hole 321 for the negative pressure tube 12 to pass through is also provided on the fixing plate 34. In this way, the function of fixing the booster airbag 31 on the bed body 1 is achieved. Among them, in order to adjust the position of the airbag relative to the pregnant woman, a U-shaped mobile frame 7 is hinged on the left and right sides of the booster plate 2, and sliding grooves 11 are respectively provided on both sides of the bed body 1. The horizontal part of the middle part of the mobile frame 7 is arranged in the sliding groove 11, and a screw sleeve 71 is welded at the bottom of the mobile frame 7. A screw 6 is provided in the screw sleeve 71, and the screw 6 is fixed to the bottom of the bed body 1. The screw 6 can be rotated to adjust the horizontal position of the mobile frame 7 on the bed body 1.

[0035] In addition, on the left side of the boosting plate 2, on the movable frame 7, a limiting block 72 is welded, and the function of the limiting block 72 is to prevent the boosting plate 2 from swinging excessively to the left. When the boosting plate 2 is not in use, it can be swung to the right to lay it flat.

[0036] After the booster airbag 31 is pushed out, in order to reduce the sagging of the middle part thereof, a spring 33 is provided on the negative pressure tube 12. When the spring 33 is extended, it can provide a part of the front support force and provide some force to support the middle part of the booster airbag 31. In addition, when the negative pressure of the booster airbag 31 shrinks, the spring 33 will also shrink, which will not affect the storage of the booster airbag 31.

[0037] The valve assembly 8 is arranged on the left and right sides of the adjusting ring 43, and a rubber gasket is provided at one end of the first one-way valve 81 and the second one-way valve 82 of the valve assembly 8 facing the pressurized chamber 41. Because the adjusting ring 43 can rotate, and the connecting hole 321 is coaxially distributed in the sink of the pressurized chamber 41, and because the adjusting ring 43 can drive the valve assembly 8 to a certain angle, so that the first one-way valve 81 or the second one-way valve 82 is connected to the connecting hole 321, the role of the rubber gasket is to provide a certain sealing performance, so that the gas in the pressurized chamber 41 can enter the valve assembly 8. The rubber gasket relies on its own certain elastic deformation to make transitional contact with the connecting hole 321 of the pressurized chamber 41.

[0038] In order to allow the gas in the pressurized chamber 41 to enter the booster airbag 31 and prop up the booster airbag 31, the present embodiment also includes a Y-shaped tube 10, and the first and second one-way valves 81 and 82 of the valve assembly 8 on the left side of the adjusting ring 43 are respectively sealedly connected to the double-end ports of the Y-shaped tube 10, and the single-end port of the Y-shaped tube 10 is sealedly connected to the booster airbag 31.

[0039] Since the adjusting ring 43 can rotate, in order to know whether the adjusting ring 43 rotates to accurately drive the first one-way valve 81 or the second one-way valve 82 to communicate with the connecting hole 321 of the pressurizing chamber 41, a reference plate 411 is provided on the side wall of the pressurizing chamber 41, and two limit plates 431 corresponding to the reference plate 411 are provided on the top of the adjusting ring 43. The limit plates 431 are located above the middle of the first one-way valve 81 and the second one-way valve 82, as shown in FIG. Figure 5 As shown, when the limiting plate 431 and the reference plate 411 above the first one-way valve 81 are in contact with each other, it indicates that the first one-way valve 81 and the connecting hole 321 of the pressurizing chamber 41 are connected. When the limiting plate 431 and the reference plate 411 above the second one-way valve 82 are in contact with each other, it indicates that the second one-way valve 82 and the connecting hole 321 of the pressurizing chamber 41 are connected.

[0040] When using the device, the booster plate 2 is erected, the booster airbag 31 is clamped on the booster plate 2, and then the screw 6 is rotated to drive the moving frame 7 and the booster plate 2 close to the pregnant woman, and the pregnant woman's feet step on the booster plate 2 to expose her genitals. At this time, the booster airbag 31 is in a negative pressure state, and the booster plate 2 is pushed until one end of the suction cup 32 of the booster airbag 31 contacts the fetal head, and then the suction cup 32 is slightly negatively adsorbed on the fetal head through the negative pressure tube 12. At this time, the valve assembly 8 on the pressurized chamber 41 is as shown in FIG. Figure 4 As shown, when the lever 5 is pressed down, the piston moves upward in the pressurized chamber 41, compressing the gas, the first one-way valve 81 on the right is closed, and the first one-way valve 81 on the left is opened, and the gas enters the booster airbag 31 through the first one-way valve 81 and the Y-tube 10, and the spring 33 pops up, and the booster component 3 starts to push the fetal head up; the lever 5 is lifted upward, and the piston is reset. During the resetting process, the first one-way valve 81 on the left side of the adjusting ring 43 is closed, and the first one-way valve 81 on the right side is opened, so that the air outside the pressurized chamber 41 is sucked into the pressurized chamber 41, and the lever 5 is pressed down again, and the above working steps are repeated, and the booster component 3 gradually pushes the fetal head up.

[0041] After the fetal head is pushed up, the booster component 3 needs to be slowly withdrawn. Figure 4 Rotate the adjusting ring 43 clockwise in the direction of arrow A until the limit plate 431 above the second one-way valve 82 and the top surface of the adjusting ring 43 are in contact with the reference plate 411, and the second one-way valve 82 is connected to the connecting hole 321 of the pressurizing chamber 41. When the lever 5 is pressed down, the piston moves upward in the pressurizing chamber 41 to compress the gas, and the first one-way valve 81 on the left is closed, and the first one-way valve 81 on the right is opened to discharge the gas; lift the lever 5 upward to reset the piston, and during the resetting process, the first one-way valve 81 on the left side of the adjusting ring 43 is opened, and the first one-way valve 81 on the right is closed, so that the air in the booster airbag 31 is sucked into the pressurizing chamber 41, and the lever 5 is pressed down again to repeat the above working steps, and the booster component 3 gradually shrinks and resets.

[0042] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the protection scope of the present application.
