Description

Technical Field

[0001] The invention belongs to the field of medical devices, in particular to a labor analgesia and delivery device. Background Art

[0002] The labor analgesia and delivery device is a medical device used in the field of obstetrics and gynecology. It aims to reduce the pain felt by mothers during labor through the integration of physical, mechanical or electronic technologies, and to assist in optimizing the progress of labor and promote the safe delivery of the fetus.

[0003] The cervical dilation balloon is a medical device commonly used for inducing labor in full-term pregnancies and assisting with difficult labor. Its core structure is a catheter with an inflatable balloon at one end. When in use, the balloon is placed into the cervical canal through the vagina, and saline or gas is injected into the balloon to expand it. The mechanical expansion force is used to gradually soften the cervix and expand the inner diameter of the cervical canal, thereby inducing uterine contractions or creating conditions for fetal delivery.

[0004] However, because the cervix is ​​located deep in the vagina, the operator must rely on finger touch or indirect observation with the help of a speculum when inserting existing cervical dilation balloons, lacking real-time visual guidance. The balloon tip lacks positioning markers or guide structures, making it difficult to accurately align with the external cervical opening. During imprecise insertion, the mechanical stimulation of the balloon on the vaginal wall can cause severe pain, especially during contractions, when tension in the mother causes vaginal muscle spasms, further increasing the difficulty of the operation. Clinically, a speculum is often used to open the vaginal opening to expose the cervix. However, traditional speculum and balloon are independent instruments, requiring separate operations. This separate operation not only increases the workload of medical staff but also reduces efficiency due to prolonged operation time. Summary of the Invention

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] As attached Figure 1 To the attached Figure 6 As shown:

[0031] Embodiment 1: The present invention provides a labor analgesia and midwifery device, comprising a positioning bracket 1, a guide branch tube 2 fixedly mounted in the middle of one end of the positioning bracket 1, a fixing hole 3 being formed through the middle of one end of the guide branch tube 2 passing through the positioning bracket 1, an adjusting branch tube 4 being movably mounted inside the fixing hole 3, the outer diameter of one end edge of the outer surface of the adjusting branch tube 4 being larger than the inner diameter of the opening of one end of the fixing hole 3, the edge of one end of the adjusting branch tube 4 being engaged with the opening of the fixing hole 3, and a cervical dilator being arranged inside the adjusting branch tube 4;

[0032] The cervical dilator includes a connecting catheter 5, which is movable through an adjusting branch tube 4. A connecting probe 7 is provided on one end of the adjusting branch tube 4. A plurality of balloons 6 are provided on one side of the outer surface of the adjusting branch tube 4 near the connecting probe 7. A wide-mouthed groove 8 is provided on one end of the adjusting branch tube 4. A guide mechanism is also provided inside the wide-mouthed groove 8 for adjusting the position of the end of the connecting probe 7.

[0033] The guide mechanism includes a plurality of guide rope holes 9, which are equidistantly opened at one side of the inner wall of the adjustment branch pipe 4. An adjustment rope 10 is movably installed inside the guide rope hole 9. One end of the adjustment rope 10 extends to the wide-mouth groove 8 and is fixedly connected to a clamping member 11. An arc-shaped groove is opened in the middle of one side of the clamping member 11. There are four clamping members 11. Two adjacent clamping members 11 are perpendicular to each other. The connecting conduit 5 is located inside the plurality of clamping members 11. The outer surface of the adjustment rope 10 is placed between the inner wall of the wide-mouth groove 8 and the outer surface of the clamping member 11, and a tension spring 12 is sleeved thereon. A limiting ball 13 is fixedly installed on the other end of the adjustment rope 10. The outer diameter of the limiting ball 13 is smaller than the inner diameter of the opening at one end of the guide rope hole 9. The guide rope hole 9 and the limiting ball 13 are engaged with each other.

[0034] The outer surface of the positioning bracket 1 is also provided with an expansion structure for expanding the vaginal opening.

[0035] As can be seen from the above, when in use, the staff will first strictly disinfect the device to ensure that it meets the medical use standards. Next, hold the positioning bracket 1 and insert the adjusting branch tube 4 into the fixing hole 3. Since the outer diameter of the edge of one end of the outer surface of the adjusting branch tube 4 is larger than the inner diameter of the opening at one end of the fixing hole 3, a firm engagement between the two can be achieved. Then, by pulling the limiting ball 13 at the other end of the adjusting rope 10, the adjusting rope 10 moves in the guide rope hole 9, driving the fixed clamping member 11 to move, and the angle of the clamping member 11 can be flexibly adjusted by utilizing the elastic action of the tension spring 12. Because an arc-shaped groove is provided in the middle of one side of the clamping member 11, and the four clamping members 11 are distributed perpendicular to each other and clamp the connecting catheter 5, multi-dimensional adjustment of the position of the end of the connecting probe 7 can be achieved, and precise alignment with the external os of the cervix can be achieved. During this process, the limiting ball 13 and the guide rope hole 9 engage with each other to prevent the adjusting rope 10 from falling off, thereby ensuring the stable operation of the guide mechanism;

[0036] The guide mechanism adjusts the position of the connecting probe 7 tip, aligning the cervical dilator's balloon 6 with the external cervical os. Then, saline or gas is injected into the balloon 6 to dilate the cervix. Throughout the entire operation, the various components of the device work closely together, achieving efficient and precise labor analgesia and midwifery, effectively alleviating maternal pain and improving the safety and success rate of midwifery.

[0037] Example 2:

[0038] Reference Figure 2 and Figure 5 The expansion structure includes a plurality of guide slots 14, which are equidistantly arranged at the front and rear ends of the positioning bracket 1. A movable block 15 is movably installed inside the guide slot 14. One end of the movable block 15 extends to the outside of the positioning bracket 1 and is fixed with an expansion piece 16. The other end of the movable block 15 extends to the outside of the positioning bracket 1 and is provided with an adjustment component for adjusting the overall position of the expansion piece 16.

[0039] As can be seen from the above, first the staff places the positioning bracket 1 in the appropriate position so that the expander 16 lightly touches the vaginal opening. Then, the movable block 15 is pushed to slide in the guide groove 14, so that the expander 16 fixed at one end of the movable block 15 gradually opens the vaginal opening. The expansion amplitude and position of the expander 16 are adjusted to adapt to the physiological characteristics of different parturient women.

[0040] Reference Figure 1 and Figure 3The adjustment component includes a connecting kit 18, which is sleeved on the outer surface of the guide branch pipe 2. A through hole is opened in the middle of one end of the connecting kit 18. The outer diameter of the guide branch pipe 2 is smaller than the inner diameter of the through hole. The guide branch pipe 2 and the through hole are embedded in each other. A plurality of connecting heads 19 are integrally formed on the outer surface of the connecting kit 18. Support connecting plates 17 are rotatably installed on both sides of the connecting head 19. The other end of the movable block 15 passes through the positioning bracket 1 and is rotatably connected to one side of the support connecting plate 17. One end of the connecting kit 18 is placed on the outer surface of the guide branch pipe 2 and a threaded sleeve 20 is rotatably installed. An external thread 21 is opened on one side of the outer surface of the guide branch pipe 2, and an internal thread is opened on one side of the inner wall of the threaded sleeve 20. The external thread 21 and the internal thread of the inner wall of the threaded sleeve 20 are adapted to each other.

[0041] As can be seen from the above, when the threaded sleeve 20 is rotated, the external threads 21 on one side of the outer surface of the guide branch tube 2 and the internal threads on the inner wall of the threaded sleeve 20 fit together, causing the connection sleeve 18 to move along the guide branch tube 2. The support connecting plates 17 rotatably mounted on both sides of the connector 19 integrally formed on the outer surface of the connection sleeve 18 push the movable block 15 to slide within the guide slot 14 as the connection sleeve 18 moves, thereby gradually causing the expansion member 16 fixed to one end of the movable block 15 to open the vaginal opening.

[0042] Working principle: When the position of the connecting probe 7 needs to be adjusted, the staff pulls the limiting ball 13 of the adjustment rope 10, and the adjustment rope 10 slides in the guide rope hole 9, driving the fixed clamping part 11 to change its angle. During the adjustment process, the tension spring 12 provides a reset force on the one hand, ensuring that the clamping part 11 stably clamps the connecting catheter 5 when there is no external force; on the other hand, it plays a buffering and fine-tuning role during the adjustment process, so that the connecting probe 7 can be accurately positioned. By pulling the adjustment rope 10 and cooperating with the tension spring 12, the angle of the connecting probe 7 can be adjusted in multiple dimensions, so that the balloon 6 can be accurately aligned with the external cervical os.

[0043] For the expansion structure, when the threaded sleeve 20 is rotated, due to the cooperation between the external thread 21 and the internal thread on the inner wall of the threaded sleeve 20, the rotational motion of the threaded sleeve 20 is converted into the linear motion of the connecting kit 18 along the guide branch tube 2. The connecting kit 18 drives the movable block 15 to slide in the guide groove 14 through the connecting head 19 and the supporting connecting plate 17, thereby causing the expansion piece 16 to expand or contract the vaginal opening. This mechanical transmission method can accurately control the movement of the expansion piece 16 and adjust the expansion amplitude and position according to actual needs.

[0044] In actual use, the vaginal opening is first opened by the expansion structure to provide good conditions for the operation of the cervical dilator, and then the balloon 6 of the cervical dilator is accurately positioned using the guiding mechanism to achieve effective expansion of the cervix, assist the delivery process, and at the same time reduce the pain and injury of the mother.
