Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to a nursing device for emergency hemostasis. Background Technology

[0002] Accidents can cause uncontrollable bleeding in a part of the body. While waiting for help, it is necessary to perform first aid to stop the bleeding and prevent a drop in blood pressure and insufficient perfusion of tissues and organs due to massive bleeding, which could lead to shock or even endanger life. Quick and effective hemostasis is a key measure to save lives and can buy time for subsequent diagnosis and treatment.

[0003] Most existing emergency hemostasis devices are tourniquets, which require tightening, fastening, and positioning during use. Generally, the single method of Velcro fastening provides insufficient pressure to the wound, making it difficult to accurately adjust to the appropriate pressure. Excessive pressure may lead to ischemic necrosis of local tissues, while insufficient pressure will not effectively stop bleeding. For example, application number CN202323570771.8 describes an emergency hemostasis tool that uses an elastic band to tighten and then attaches a second adhesive band to a corresponding adhesive band for fixation. However, this device has the following drawbacks: it relies solely on tightening and fastening to achieve hemostasis, requiring repeated adjustments to the adhesive position to apply pressure to the wound. If operated improperly, the tourniquet may detach due to unstable adhesion or insufficient pressure, failing to achieve hemostasis. Utility Model Content

[0033] The following is a detailed description of this novel experimental design with reference to the accompanying drawings:

[0034] Figure 1-6 This invention discloses an emergency hemostasis nursing device, comprising: a fixing strap 1, and further comprising:

[0035] The semi-circular fixed shell 2 has a Π-shaped hollow structure inside, and a limit component 3 is provided on the outer wall of the semi-circular fixed shell 2. The outer wall of the semi-circular fixed shell 2 is provided with a through hole I 22 and a through hole II 23 in parallel, and the two ends of the semi-circular fixed shell are respectively provided with an outlet hole I 24 and an outlet hole II 25.

[0036] The D-ring buckle 4 has a slenderly connected rotating rod 5. The rotating rod 5 is detachably connected to the limiting component 3 and is sleeved between the inner side of the middle section of the fixing band 1 and the D-ring buckle 4. The two ends of the fixing band 1 pass through the D-ring buckle 4 first and then through the insertion hole I 22 and the insertion hole II 23 respectively.

[0037] The compression assembly 6 is connected to both ends of the fixing belt 1 that passes through the outlet hole I 24 and outlet hole II 25 via fixing rings 7 provided on both sides;

[0038] A cotton pad 8 is disposed within the compression assembly 6, and a release film 81 is adhered to the surface of the cotton pad 8.

[0039] Working principle:

[0040] To install the hemostatic nursing device, first pass both ends of the fixing strap 1 through the D-ring buckle 4 (so that the rotating rod 5 is fitted on the inner side of the middle section of the fixing strap 1 between the D-ring buckle 4), then pass both ends of the fixing strap 1 through the D-ring buckle 4 through the insertion hole I 22 and the insertion hole II 23 respectively into the semi-circular fixing shell 2. Through the hollow position, the two ends of the fixing strap 1 pass out through the exit hole I 24 and the exit hole II 25 respectively, and are fixed with the fixing ring 7 to complete the installation. It can then be placed in the first aid kit and taken out when needed.

[0041] The method of using the hemostatic nursing device is as follows: The injured person puts the device on the injured area and tears off the isolation film 81 so that the wound comes into contact with the cotton swab 8. Then, remove the rotating rod 5 on the limiting component 3, hold the rotating rod 5 and pull it backward so that the excess length of the fixing band 1 comes out through the insertion hole I 22 and insertion hole II 23 of the semi-circular fixing shell 2, completing the first step of tightening. Then, manually rotate the rotating rod 5 so that the two ends of the fixing band 1 that have come out continuously wrap around each other. At this time, the fixing band 1 connected between the fixing ring 7 on the compression component 6 and the outlet hole I 24 and outlet hole II 25 of the semi-circular fixing shell 2 is tightened inward and pressed against the skin surface until the wound is completely tightened, thus fixing the wound. Then, put the rotating rod 5 back on the limiting component 3 to prevent the fixing band 1 from loosening during use and to ensure the stability of the device.

[0042] If the patient's wound is still bleeding or feels too much pressure, the pressure component 6 can be used to apply or reduce pressure on the wound. The former compresses the blood vessels at the wound to reduce bleeding, while the latter is away from the wound to avoid excessive pressure causing local ischemic necrosis. At the same time, the cotton pad 8 on the pressure component 6 comes into contact with the wound to promote blood clotting and accelerate the hemostasis process.

[0043] Once the bleeding from the wound is under control and the patient has received treatment, medical staff can directly remove the rotating rod 5 from the limiting component 3, causing the winding part of the fixing strap 1 to loosen and recover. The device can then be removed from the wound, making disassembly and removal simple and convenient for medical staff to quickly carry out subsequent treatment.

[0044] Among them, ① the fixing strap 1 is made of a flexible material (such as bamboo fiber composite material) with certain breathability and sweat absorption effect, natural antibacterial properties, sweat absorption and quick drying, to avoid secondary damage caused by patient discomfort or skin irritation.

[0045] ② The cotton wool block 8 uses an existing composite structure layer, specifically:

[0046] The surface is an absorbent layer (materials such as medical-grade non-woven fabric or degreased gauze) that quickly absorbs blood and wound exudate, forming a gel-like structure to prevent blood from flowing out.

[0047] The second layer is an antibacterial sustained-release layer (using materials such as chitosan / calcium alginate composite membrane), which continuously releases silver ions to inhibit bacterial growth and promotes thrombin generation through calcium ion cross-linking.

[0048] The third layer is the physical hemostatic layer (using materials such as modified cellulose hemostatic fibers), which accelerates platelet aggregation through the physical adsorption between fibers, forming a mechanical hemostatic barrier.

[0049] The fourth layer is a biocompatible interface layer (materials such as medical-grade silicone coating), which isolates the wound from the outer structure and prevents the dressing from adhering to the wound surface;

[0050] Finally, a low-density polyethylene microporous membrane is used at the point of contact with the compression component 6 to maintain the three-dimensional structure of the cotton block 8 and prevent the material from shifting when pressure is applied.

[0051] ③ The inner side of the semi-circular fixing shell 2 has a multi-toothed structure 21. When the fixing strap 1 is tightened, the toothed structure can bite the material of the fixing strap 1, increase friction, and prevent rebound and loosening. The inner side of the semi-circular fixing shell 2 is made of a flexible material (such as bamboo fiber composite material) with a certain breathability and sweat absorption effect.

[0052] ④ A rotating rod 5 is stretchably connected to the D-ring buckle 4. In actual use, an elastic rope 41 with a certain toughness (such as composite fiber or polyurethane) can be selected, passed through the rotating rod 5 and fixedly installed on the D-ring buckle 4 to prevent the rotating rod 5 from slipping off the fixing strap 1 and being lost.

[0053] ⑤ To increase practicality, in actual use, a storage box 9 is provided at the lower end of the outer wall of the semi-circular fixed shell 2, and the structure of the storage box 9 includes:

[0054] The outer shell 91 is fixed on the semi-circular fixed shell 2, and the top of the outer shell 91 is provided with a double slot 92; the flip cover 93 is hinged inside the outer shell 91, and the top of the flip cover 93 is provided with a clamp-shaped slider 94 that is snapped into the double slot 92.

[0055] In the initial state, the clamp-shaped slider 94 on the top of the flip cover 93 will engage with the double slot 92 on the top of the outer shell 91, effectively preventing items inside the storage box 9 from falling out or being contaminated by the outside.

[0056] When the storage box 9 needs to be opened, the injured person (in actual use, the flip cover 93 has a handle 95 on the outside for easy access) only needs to apply an outward horizontal push to the pincer slider 94. Since the connection between the pincer slider 94 and the double slot 92 is not completely fixed, the pincer slider 94 can slide within the double slot 92 until it is released from the latch limit of the double slot 92. At this time, since the flip cover 93 is hinged in the outer shell 91, the flip cover 93 rotates clockwise, and the injured person can take out the items in the storage box 9 (painkillers or compressed alcohol can be placed in the storage box 9; the former is used to relieve wound pain, and the latter can be used to simply disinfect the skin around the wound to avoid cross-infection).

[0057] After using the storage box 9, rotate the flip cover 93 counterclockwise, and the clamp-shaped slider 94 will re-lock into the double slot 92, completing the closing of the storage box 9;

[0058] In summary, this device has a simple structure and is easy to operate. It can be quickly used to perform hemostasis in a tense emergency environment. This emergency hemostasis nursing device achieves pressure hemostasis on the wound through the coordinated work of components such as the fixing strap 1, the semi-circular fixing shell 2, the rotating rod 5, the compression component 6, and the cotton swab 8. The tightness can be flexibly adjusted according to the specific condition of the patient's wound, and there will be no twisting or deformation during fixation.

[0059] In the above scheme, the bottom end of the rotating rod 5 is provided with an external thread 51, and the upper end is fitted with a handle 52.

[0060] The structure of the limiting component 3 includes:

[0061] The limiting ring I31 is open and located at the uppermost end of the outer wall of the semi-circular fixed shell 2. The handle 52 is snapped together with the limiting ring I31.

[0062] The limiting ring I32 has an internal thread 33 on its inner wall and is located in the middle section of the outer wall of the semi-arc fixed shell 2 relative to the limiting ring I31. The external thread 51 is bolted to the internal thread 33.

[0063] Working principle:

[0064] The specific detachable connection method between the rotating rod 5 and the limiting component 3 is as follows:

[0065] Insert the upper end of the rotating rod 5 into the opening of the limiting ring I 31, and then move the rotating rod 5 downward so that the external thread 51 at its bottom end slides along the internal thread 33 of the limiting ring II 32 to achieve fixation.

[0066] At this time, the rotating rod 5 is fixed by the limiting ring I 31 and the limiting ring II 32 and cannot rotate freely. The tightness of the fixing band 1 is also fixed, ensuring stable pressure on the wound and achieving the purpose of hemostasis.

[0067] When it is necessary to remove the rotating rod 5, first rotate the rotating rod 5 in the opposite direction so that the external thread 51 slides along the internal thread 33 of the limiting ring II 32. Then apply a certain external force to the handle 52. Since it is a snap-fit ​​connection, the rotating rod 5 can be disengaged from the limiting ring I 31.

[0068] As described above, the structure of the compression component 6 includes:

[0069] The outer shell 61 has the fixing rings 7 on both sides, and the inner wall of the outer shell 61 has vertical sliding grooves 62 on both sides. The outer shell 61 has threaded holes 63 through it.

[0070] The movable block 64 has vertically movable sliders 65 on both sides, and the sliders 65 are slidably connected to the groove 62. The top of the movable block 64 has a concave groove 66, and the bottom of the movable block 64 has the cotton wool block 8.

[0071] The telescopic rod 67 has a threaded section in its middle section, and the thread is bolted to the threaded hole 63. The bottom of the telescopic rod 67 has a protruding disc 68, and the disc 68 is slidably connected to the slot 66.

[0072] Working principle:

[0073] The outer shell 61 is connected to the fixing belt 1 through the fixing rings 7 on both sides to complete the assembly of the whole device. When it is necessary to adjust the pressure on the wound, rotate the telescopic rod 67 (in actual use, the top of the telescopic rod 67 is connected to a rotating handle 69). Since the thread of the telescopic rod 67 and the threaded hole 63 of the outer shell 61 are engaged with each other, rotating the telescopic rod 67 will make it move vertically along the axis, and the moving block 64 will move up and down, thereby driving the cotton swab 8 connected to it to move closer to or away from the wound, so as to achieve precise adjustment of the pressure.

[0074] For example, when it is necessary to increase the pressure, the telescopic rod 67 is rotated in the positive direction to move it downward, pushing the moving block 64 and the cotton swab 8 to press more tightly against the wound; conversely, rotating the telescopic rod 67 in the negative direction reduces the pressure to avoid excessive pressure causing ischemic necrosis.

[0075] Among them, ① throughout the process, the cooperation between the slide 62 and the slider 65 ensures the smoothness and straightness of the movement of the moving block 64;

[0076] ② The design of the concave groove 66 and the convex disc 68 means that when the telescopic rod 67 rotates, the disc 68 at its bottom will rotate freely in the groove 66, ensuring that the rotation of the telescopic rod 67 only pushes the moving block 64 vertically, without causing the moving block 64 itself to rotate, thus ensuring the accuracy of the pressing direction.

[0077] In summary, by finely adjusting the telescopic rod 67, the pressure can be precisely controlled. Whether it is minor bleeding or more serious bleeding, the best hemostatic effect can be achieved through flexible adjustment, thus improving the efficiency of hemostasis.

[0078] For patients of different ages and physical conditions, the pressure can be flexibly adjusted to meet their different tolerance levels. At the same time, the self-locking property of the thread ensures that the telescopic rod 67 will not easily move due to external force, thus ensuring the stability of the pressure and providing effective pressure hemostasis.

[0079] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
