Description

Technical Field

[0001] This invention relates to medical and nursing techniques, specifically to a hemostatic device for clinical nursing. Background Technology

[0002] In clinical nursing, pressure hemostasis for arterial bleeding has always been an important procedure. Traditional pressure hemostasis methods often rely on the experience of medical staff and manual operation, lacking precise positioning and pressure control. For example, when using ordinary pressure tools or relying solely on manual pressure, it is difficult to ensure that the pressure is accurately aligned with the artery, which can easily lead to hemostasis failure or delay, posing risks to the patient's health.

[0003] Chinese invention patent CN119970138B discloses a nursing compression hemostasis device, including a core compression mechanism. The core compression mechanism includes an upper annular frame; symmetrical side connecting ears are provided on both sides of the upper annular frame; and an adjustable restraint strap is included, with both ends of the adjustable restraint strap fixed to the side connecting ears. Precise positioning and pressure application: The ingenious design of the upper annular frame, sliding track, and core functional housing in the core compression mechanism ensures that the outer and inner elastic compression pads are precisely aligned with the patient's artery. The stable sliding of the guide block within the elongated guide groove not only provides precise guidance for the movement of the core functional housing but also allows the compression pads to be flexibly adjusted according to actual needs, thereby ensuring precise pressure on the artery, greatly improving the success rate and effectiveness of hemostasis, and effectively reducing hemostasis failure or delay caused by inaccurate compression positioning.

[0004] However, in actual application, it is first positioned by the upper ring frame and the binding strap, and then the core functional shell is pushed so that the pressing block can be pressed into the position where hemostasis is needed. However, in this pressing method, the pressing block is inside the elastic pressing pad when initially positioned. Its specific position is not only blocked by the elastic pressing pad, but also by the sliding track and other structures. Therefore, it is not possible to accurately position the pressing block, resulting in insufficient actual hemostasis effect. Summary of the Invention

[0005] The purpose of this invention is to provide a hemostatic device for clinical nursing to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hemostatic device for clinical nursing, comprising a ring shell, connecting rings symmetrically arranged on both sides of the ring shell, an adjustable strap connecting the two connecting rings, a pressing seat slidably connected to the inner side of the ring shell, a pressing block arranged at the bottom of the inner side of the pressing seat, and a pressing adjustment unit arranged on the outside of the pressing block.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: Please see Figures 1-5 A hemostatic device for clinical nursing includes a ring shell 1, with connecting rings 101 symmetrically arranged on both sides of the ring shell 1, and an adjustable strap 102 connecting the two connecting rings 101.

[0023] It should be noted that the adjustable strap 102 is made of non-elastic material, which can effectively ensure the stability of the ring shell 1 during the binding process.

[0024] A pressing seat 2 is slidably connected to the inner side of the ring shell 1. A pressing block 21 is provided at the bottom inside the pressing seat 2. A pressing adjustment unit is provided on the outside of the pressing block 21. The inner side of the ring shell 1 is provided with multiple sets of vertical grooves 22 at equal intervals in a circular shape. The outer side of the pressing seat 2 is fixedly connected to a positioning block 23 that is slidably connected to the inner side of the vertical groove 22. The surface of the positioning block 23 is provided with a straight groove extending into the interior of the pressing seat 2. The inner side of the straight groove is slidably connected to a support block 24. A top pressure spring 25 is fixedly connected between the support block 24 and the inner wall of the straight groove. The inner wall of the vertical groove 22 is fixedly connected to a limiting block 26 corresponding to the support block 24. The ends of the limiting block 26 and the support block 24 facing each other are provided with arc-shaped portions 27.

[0025] It should be noted that when the positioning block 23 abuts against the bottom of the inner wall of the vertical groove 22, the arc portion 27 at the end of the limiting block 26 abuts against the arc portion 27 at the end of the support block 24, and the bottom end of the pressing block 21 is located below the outside of the ring shell 1. When the positioning block 23 abuts against the top of the inner wall of the vertical groove 22, the bottom surface of the pressing block 21 is flush with the bottom surface of the ring shell 1.

[0026] In this embodiment, the pressing adjustment unit includes a first threaded groove 3 opened inside the pressing seat 2. A first adjusting screw 31 is threadedly connected inside the first threaded groove 3. The pressing block 21 is rotatably connected to the bottom of the first adjusting screw 31. A first receiving groove 32 communicating with the first threaded groove 3 is opened at the bottom of the pressing seat 2. Multiple sets of first guide grooves 33 are opened in an annular shape on the inner side of the first receiving groove 32. A first guide block 34 that is slidably connected to the inner wall of the first guide groove 33 is fixedly connected to the top of the outer side of the pressing block 21.

[0027] It should be noted that the first threaded groove 3 is concentrically arranged with the pressing seat 2, and the pressing block 21 is slidably connected to the inner side of the first receiving groove 32.

[0028] In clinical use, medical staff align the pressure block 21 protruding from the outside of the ring shell 1 with the blood vessel to be pressed on the patient's body surface, and then use the adjustable strap 102 to bind the ring shell 1 to the patient's body surface. After that, the medical staff applies pressure to the ring shell 1. During this process, if the patient's body surface cannot withstand slightly greater pressure, the medical staff can lift the pressure seat 2 to a certain extent so that the pressure on the patient's body surface is not too great when pressing the ring shell 1. If the pressing area can withstand slightly greater pressure, the medical staff can directly apply pressure to the ring shell 1, so that it and the limiting block 26 inside the pressure seat 2 apply pressure to the support block 24. In addition, with the cooperation of the arc part 27, the support block 24 overcomes the deformation force of the top pressure spring 25 and moves into the straight groove, so that the limiting block 26 can pass through the support block 24. At this point, the limiting block 26 no longer cooperates with the supporting block 24 to restrict the movement of the ring shell 1, allowing the ring shell 1 to come into contact with the patient's body surface. Afterwards, the medical staff adjust the adjustable strap 102 again so that the ring shell 1 can be stably pressed against the patient's body. Then, the operator rotates the first adjusting screw 31, which, with the cooperation of the first threaded groove 3, drives the pressing block 21 to move toward the patient's body surface, so that the contact pressure between the pressing block 21 and the patient's body surface gradually increases, and the blood vessels at that point are compressed, thereby achieving an effective hemostasis effect.

[0029] It should be noted that this device can be used not only for hemostasis on limbs, but also for other body parts such as the chest and abdomen. Furthermore, its application is not limited to arterial hemostasis; it can also be used for venous bleeding, which is common in clinical nursing, such as hemostasis after removing an IV needle from the back of the hand, bleeding from surgical abdominal wounds, bleeding from orthopedic limb wounds, and visible bleeding from superficial parts of the body. During use, it can be used in conjunction with medical cotton or gauze for hemostasis.

[0030] Example 2: Please see Figures 2-3 , Figure 5 This embodiment provides a technical solution based on the above embodiments: the pressing base 2 is provided with an adapter mechanism, the adapter mechanism includes a second threaded groove 4 opened inside the first adjusting screw 31, the inner side of the second threaded groove 4 is threadedly connected to the second adjusting screw 41, the bottom of the second adjusting screw 41 is rotatably connected to a spare block 42, the bottom of the first adjusting screw 31 is provided with a second receiving groove 43 communicating with the second threaded groove 4, the inner wall of the second receiving groove 43 is provided with multiple sets of second guide grooves 44 in an annular shape at equal intervals, and the side of the spare block 42 is fixedly connected to a second guide block 45 that is slidably connected to the inner wall of the second guide groove 44.

[0031] It should be noted that the second threaded groove 4 is concentrically set with the first threaded groove 3, and the spare block 42 is slidably connected to the inner side of the second receiving groove 43.

[0032] When encountering situations where there is a thick layer of body fat or a lot of muscle causing blood vessels to be hidden deep, medical staff can use a spare block 42 with a smaller contact area with the patient's body surface to compress and stop bleeding. During the operation, the ring shell 1 is installed in the same way. Then, by rotating the second adjusting screw 41, the spare block 42 is driven to move towards the patient's body surface, so that the contact pressure between the spare block 42 and the patient's body surface continuously increases. Because the contact pressure between it and the patient's body surface is small, it can move a greater distance in a local area on the patient's body surface, thereby pressing on blood vessels that are hidden deep in the body.

[0033] Example 3: Please see Figures 3-4This embodiment provides a technical solution based on the above embodiment: Both the first adjusting screw 31 and the second adjusting screw 41 are provided with auxiliary units on their exteriors. Each auxiliary unit includes a tolerance groove 5, equidistantly spaced in a circular shape on the outer surfaces of the first adjusting screw 31 and the second adjusting screw 41. An adjusting block 51 is slidably connected to the inner surface of the tolerance groove 5. A pressure spring 52 is fixedly connected between the top of the adjusting block 51 and the inner wall of the tolerance groove 5. A fixing ring 53 is slidably connected to the outer surfaces of both the first adjusting screw 31 and the second adjusting screw 41. The adjusting block 51 is fixedly connected to the fixing ring 53. A plurality of positioning inserts 54 are equidistantly spaced in a circular shape on the bottom surface of the fixing ring 53. Positioning grooves 55 corresponding to the positioning inserts 54 are provided on the surface of the pressing seat 2 and the surface of the first adjusting screw 31.

[0034] When it is necessary to rotate the first adjusting screw 31, the medical staff pulls the fixing ring 53 on the first adjusting screw 31 outward, causing it to drive the external positioning insert 54 out of the positioning groove 55, so that the rotation of the first adjusting screw 31 is no longer restricted. At this time, the operator can rotate the first adjusting screw 31 to adjust the contact pressure between the pressing block 21 and the patient's body surface. When rotating the second adjusting screw 41, the same steps are used to release the restriction on the rotation of the second adjusting screw 41.

[0035] Example 4: In order to effectively reduce the discomfort during the hemostasis process, this embodiment provides a technical solution based on the above embodiment: the bottom of the ring shell 1, the bottom of the pressing seat 2, the bottom of the pressing block 21 and the bottom of the spare block 42 are all provided with soft rubber pads, so that when pressing to stop bleeding in contact with the patient's body surface, the discomfort of hard contact can be effectively reduced.

[0036] Example 5: To improve ventilation of the patient's body surface during pressure hemostasis, this embodiment provides a technical solution based on the above embodiment: the pressure seat 2 has a ventilation groove that runs through both the upper and lower ends, so that the ventilation around the pressure site is better when performing vascular pressure hemostasis, which can effectively reduce the discomfort caused by sweating in the pressure site and the covered area due to the large coverage area.

[0037] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
