Description

Technical Field

[0001] This invention relates to the field of medical hemostasis technology, specifically a device for stopping bleeding from perineal episiotomy wounds. Background Technology

[0002] In hospital clinical practice, obstetric and gynecological medical staff often perform episiotomy to shorten the labor process in order to protect the baby's safety or to prevent the mother's perineum from tearing extensively.

[0003] After an episiotomy, the patient will bleed continuously. At this time, the hospital will usually perform temporary hemostasis and then suture. However, the existing hemostasis equipment is too inefficient in the process of stopping the bleeding and cannot tighten the episiotomy site to reduce the amount of bleeding and facilitate the subsequent suturing surgery. Therefore, there is an urgent need to design an episiotomy wound hemostasis device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a perineal episiotomy wound hemostasis device to solve the problem mentioned in the background art that the existing hemostasis devices are too inefficient during the hemostasis process, and cannot pull the patient's episiotomy site closer to reduce the amount of bleeding and facilitate the patient's subsequent suturing surgery.

[0012] Preferably, the upper surface of the movable plate is provided with a rectangular groove, and a circular groove is provided above the groove of the movable plate. The rectangular groove and the circular groove of the movable plate are connected to each other. The outer ring of the bearing is fixedly connected to the circular groove of the movable plate, and the inner ring of the bearing is fixedly connected to the movable column. The movable column passes through the circular groove of the movable plate and is fixedly connected to the gear. During the rotation of the movable column, the bearing does not affect the change of position of the movable plate.

[0013] Preferably, a ratchet mechanism is provided on the rectangular groove of the movable plate, and a first fixed post and a second fixed post are fixedly connected to the rectangular groove of the movable plate. A limit ring is fixedly connected to the surface of the first fixed post. The limit ring of the first fixed post ensures that the ratchet block is always engaged with the gear. The first spring restricts the gear by means of its elastic force, and the gear can only rotate in one direction.

[0014] Preferably, the surface of the second silicone outer frame has a circular hole and a guide groove. The cover plate slides on the guide groove of the second silicone outer frame via a slider.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Two sets of second films adhere to the injured skin of the patient. The movement of the second films on the patient's skin is driven by the movement between the rack and pinion on the first silicone frame. Guided and fixed by the ratchet mechanism, the lateral incision skin of the patient is continuously brought inward, while the position of the gear does not change in the opposite direction, ensuring that the wound of the lateral incision skin is squeezed together, preventing rebleeding of the lateral incision site. At the same time, the outer surface of the 01 is soft and has an anti-friction mechanism, which can be used well on the patient's perineal lateral side without causing inconvenience. After hemostasis is completed, the lateral incision site is ready for suturing, allowing the nurse to suture the lateral incision site more quickly and reduce the patient's pain.

[0018] 2. By replacing the hemostatic block, it is not necessary to remove the soft pad attached to the skin when changing hemostatic devices for patients. Replacing the hemostatic block reduces the waste of medical resources and makes the replacement work faster and more efficient. Most importantly, the patient's episiotomy site cannot be touched. This replacement method does not cause the patient to bleed again, improves safety, and reduces risks. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 8 One embodiment provided by the present invention:

[0030] Perineal episiotomy wound hemostasis device, including:

[0031] The fabric body includes a soft sheet 1, which is fan-shaped for easier application to the perineum. A hemostatic drug block 11 is placed on the surface of the soft sheet 1. A first film 12 is fixedly connected to the lower surface of the soft sheet 1, and a first protective paper 13 is fixedly connected to the lower surface of the first film 12. By tearing the first protective paper 13 off the first film 12, the position of the soft sheet 1 can be fixed by sticking the first film 12 to the skin.

[0032] The extrusion mechanism includes a first silicone outer frame 2, which is fixedly connected to the surface of the flexible film 1. A movable plate 21 is fixedly connected to the surface of the first silicone outer frame 2. A connecting plate 22 is fixedly connected to the surface of the movable plate 21. A second film 23 is fixedly connected to the surface of the connecting plate 22. A second protective paper sheet 24 is fixedly connected to the surface of the second film 23. A rack 25 is fixedly connected to the surface of the first silicone outer frame 2. A bearing 28 is fixedly connected to the surface of the movable plate 21. A movable column 27 is fixedly connected to the surface of the bearing 28. A gear 26 is fixedly connected to the surface of the movable column 27.

[0033] Furthermore, the surface of the movable plate 21 is provided with a ratchet mechanism, which includes a first fixed post 3, the first fixed post 3 is fixedly connected to the surface of the movable plate 21, a ratchet block 31 is movably connected to the surface of the first fixed post 3, a first spring 32 is fixedly connected to the surface of the ratchet block 31, and a second fixed post 33 is fixedly connected to the surface of the first spring 32.

[0034] Furthermore, the surface of the film 1 is provided with a replacement mechanism, which includes a second silicone outer frame 4. The second silicone outer frame 4 is fixedly connected to the upper surface of the film 1. A cover plate 41 is movably connected to the surface of the second silicone outer frame 4. A filter screen 42 is fixedly connected to the surface of the film 1. A slider 43 is fixedly connected to the surface of the cover plate 41. A second spring 44 is fixedly connected to the surface of the second silicone outer frame 4. A guide post 45 is fixedly connected to the surface of the second spring 44. A locking rod 46 is fixedly connected to the surface of the guide post 45.

[0035] Furthermore, the extrusion mechanism and the replacement mechanism are equipped with an anti-friction mechanism, which includes a first rubber ring 5, which is fixedly connected to the outer surface of the cover plate 41, a second rubber ring 51, which is fixedly connected to the outer surface of the clamping rod 46, and a third rubber ring 52, which is fixedly connected to the outer surface of the first silicone outer frame 2.

[0036] Furthermore, the surface of the film 1 has three sets of square holes. The square holes on both sides of the film 1 are equipped with a pressing mechanism, and the square hole in the middle of the film 1 is equipped with a replacement mechanism. The inner surface of the first silicone outer frame 2 is provided with a guide groove. The movable plate 21 slides on the guide groove of the first silicone outer frame 2. The rack 25 is fixedly connected to the guide groove of the first silicone outer frame 2. The rack 25 and the gear 26 maintain a meshing relationship. During the rotation of the rack 25, it drives the connecting plate 22 and the second film 23 to slide together on the giant hole of the film 1. Tearing off the second protective paper 24 can fix the second film 23 on the patient's skin. The movement of the second film 23 causes the patient's skin to move.

[0037] Furthermore, a rectangular groove is provided on the upper surface of the movable plate 21, and a circular groove is provided above the groove of the movable plate 21. The rectangular groove and the circular groove of the movable plate 21 are connected to each other. The outer ring of the bearing 28 is fixedly connected to the circular groove of the movable plate 21, and the inner ring of the bearing 28 is fixedly connected to the movable column 27. The movable column 27 passes through the circular groove of the movable plate 21 and is fixedly connected to the gear 26. During the rotation of the movable column 27, the bearing 28 does not affect the change of position of the movable plate 21. During the movement of the movable plate 21 on the rectangular hole of the film 1, the rack 25 and the gear 26 always maintain a meshing relationship. During the inward sliding of the two sets of movable plates 21, the second film 23 drives the skin at both ends of the lateral cut to move inward until the lateral cut skin is squeezed together to prevent blood from flowing out.

[0038] Furthermore, a ratchet mechanism is provided on the rectangular groove of the movable plate 21. The first fixed post 3 and the second fixed post 33 are fixedly connected to the rectangular groove of the movable plate 21. A limit ring is fixedly connected to the surface of the first fixed post 3. The limit ring of the first fixed post 3 ensures that the ratchet block 31 is always engaged with the gear 26. The first spring 32 restricts the gear 26 by the elastic force of the ratchet block 31. The gear 26 can only rotate in one direction. The ratchet block 31 restricts the direction of rotation of the gear 26, so that the movable plate 21 can only move to one position on the surface of the film 1. The movable plate 21 can only move towards the middle to prevent the stretching of the second film 23 by the skin and the sliding back of the movable plate 21.

[0039] Furthermore, a circular hole is formed on the surface of the second silicone outer frame 4, and a guide groove is formed on the surface of the second silicone outer frame 4. The cover plate 41 slides on the guide groove of the second silicone outer frame 4 via the slider 43. One end of the guide groove of the second silicone outer frame 4 is closed, and the other end is open. The cover plate 41 can slide out of the surface of the second silicone outer frame 4 through the opening of the guide groove of the second silicone outer frame 4. By sliding the cover plate 41 away, the hemostatic block 11 inside the cover plate 41 can be replaced. The hemostatic block 11 will reduce its effectiveness after a certain period of use. If the soft film 1 is completely disassembled, it will cause bleeding again.

[0040] Furthermore, the second spring 44 and the guide post 45 are both on the circular hole of the second silicone outer frame 4. The guide post 45 keeps the gear 26 horizontal on the second silicone outer frame 4. The cover plate 41 and the locking rod 46 are abutted and connected to the second silicone outer frame 4. The locking rod 46 is locked on the circular hole of the second silicone outer frame 4 through the guide post 45 to limit the cover plate 41 from sliding out. The locking rod 46 limits the cover plate 41 on the second silicone outer frame 4, ensuring that the hemostatic block 11 will not fall off the soft film 1.

[0041] Furthermore, the materials of the first silicone outer frame 2 and the second silicone outer frame 4 are soft, reducing friction on the patient's skin. The first rubber ring 5, the second rubber ring 51, and the third rubber ring 52 are fixed to the first silicone outer frame 2 and the second silicone outer frame 4 to prevent friction on the skin. At the same time, rigid structures such as gears 25 and racks 26 are inside the first silicone outer frame 2 and the second silicone outer frame 4. The interior of the first silicone outer frame 2 and the second silicone outer frame 4 has sufficient rigidity to support the operation of the internal structure, making the overall structure of the film 1 relatively soft, so that the patient's skin will not feel friction from the surface of the film.

[0042] Working principle: A square hole is made in the film 1, and the first silicone outer frame 2 is installed in the square hole. A guide groove is made on one side of the square hole of the film 1. A rack 25 is installed on the guide groove of the film 1. The movable plate 21 slides on the square hole of the film 1 through the meshing relationship between the gear 26 and the rack 25. The sliding of the movable plate 21 drives the movement between the connecting plate 22 and the second film 23. The second film 23 is attached to the injured skin of the patient. The movement of the two sets of second films 23 drives the movement of the skin. A ratchet mechanism is set on the surface of the rectangular groove of the movable plate 21 to ensure the direction of movement of the first protective paper 13 on the film 1, so that the direction of movement of the skin driven by the second film 23 is always towards the inside. The overall structure of the film 1 is soft and can be used well on the outside of the patient's perineum.

[0043] A rectangular hole is made on the surface of the film 1, and a second silicone outer frame 4 and a cover plate 41 are installed on the rectangular hole. The hemostatic block 11 is placed on the upper surface of the filter screen 42, and the cover plate 41 is set above the hemostatic block 11. The cover plate 41 slides on the guide groove of the second silicone outer frame 4 via a slider 43. A second spring 44 and a guide post 45 are installed on the guide hole on the surface of the second silicone outer frame 4. Under the elastic force of the second spring 44, the height of the guide post 45 and the locking rod 46 can be changed. The cover plate 41 is limited by the change in the height of the locking rod 46. When it is necessary to replace the hemostatic block 11, the locking rod 46 is pulled higher than the cover plate 41, so that the cover plate 41 slides out of the upper surface of the second silicone outer frame 4. The cover plate 41 can be fixed on the upper surface of the second silicone outer frame 4 by repeating the operation.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
