Description

Technical Field

[0001] The present invention relates to the technical field of hemostatic devices, in particular to a limb pressing hemostatic device for emergency use. Background Art

[0002] Limb compression hemostasis devices are key medical devices used for emergency hemostasis, and are widely used for local compression after trauma emergency care, postoperative care, and interventional therapy. After a radial artery blood draw or puncture, bleeding, hematoma formation, and other complications are prone to occur due to the superficial location and high pressure of the radial artery. Therefore, long-term continuous compression is required to ensure complete closure of the puncture site. Traditionally, this compression is usually performed manually by medical staff, which is not only time-consuming and labor-intensive, but also difficult to ensure constant pressure and precise positioning, increasing patient discomfort and the risk of complications.

[0003] To address these issues, radial artery compression hemostats were developed. These devices are specifically designed for post-radial artery puncture hemostasis. Through an adjustable strap system and a precise pressure-applying module, they achieve stable and uniform compression at the puncture site. Modern radial artery hemostats are typically equipped with a pressure indicator or fine-tuning knob, allowing medical professionals to set the appropriate pressure based on individual patient differences (such as vascular elasticity and blood pressure levels). This prevents complications such as insufficient compression leading to bleeding or excessive compression leading to vascular occlusion and hand ischemia.

[0004] As in the prior art, the patent with patent authorization announcement number CN220236955U discloses a radial artery compression hemostat, including a support plate, a pressure regulator, a first strap, an adjusting screw, a positioning plate, a positioning bolt, a pressure block, a push plate, a pressure plate and a fixing assembly. The fixing assembly includes a connecting plate, a connecting rod, a G-type buckle, and a fixing ring. When using the utility model, the positioning bolt fixes the positioning plate to ensure that the pressure regulator is always in the middle of the support plate. One side of the first strap is fixed to the connecting plate by the connecting rod, and the other side is connected by wrapping the fixing ring to fix the G-type buckle on the other side of the first strap. The fixing ring can be contracted to different lengths, and the G-type buckle can quickly lock the second strap. Then, the pressure regulator can be tightened by adjusting the screw to increase the pressure to push the push plate, and the push plate moves in the pressure groove of the pressure block to apply pressure to the patient's wound.

[0005] However, during the use of the above-mentioned compression hemostat, when the patient goes to the toilet or needs to clean his hands, the device lacks an effective waterproof design and cannot provide good waterproof protection for the puncture site. Moisture can easily penetrate along the edge of the compression pad, directly contaminating the puncture point and increasing the patient's risk of infection. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a first aid limb compression hemostasis device, the specific technical solution is as follows:

[0008] In some embodiments, adsorption blocks are fixedly connected to both sides of the surface of the mounting plate, and two magnetic blocks corresponding to the positions of the adsorption blocks are fixedly connected to the bottom surface of the fixing plate.

[0009] In some embodiments, the protective film and the folding film are both hydrophilic PU films.

[0010] In some embodiments, a buffer ring is fixedly connected to the bottom surface of the positioning ring, and the buffer ring is wrapped by a protective film.

[0011] In some embodiments, a plurality of anti-slip particles are fixedly connected to the bottom surface of the protective film.

[0012] In some embodiments, the top surface of the positioning ring is fixedly connected to two limit plates, the surface of the mounting plate is provided with a connecting groove corresponding to the position of the limit plate, the bottom surface of the fixed plate is provided with a slot corresponding to the position of the limit plate, telescopic grooves are provided on both sides of the fixed plate, and a connecting rod is slidably connected in each of the telescopic grooves, one end of the connecting rod located in the fixed plate is fixedly connected to the connecting plate, a movable groove corresponding to the position of the connecting plate is provided in the fixed plate, and an insertion rod is fixedly connected to the other end of the connecting plate, and a sliding groove corresponding to the position of the insertion rod is provided on the inner wall of the movable groove, and a limiting hole corresponding to the position of the insertion rod is provided on the top of the limit plate.

[0013] In some embodiments, a movable plate is fixedly connected to the middle of the connecting rod, a compression groove corresponding to the position of the movable plate is opened in the fixed plate, a return spring is fixedly connected in the compression groove, and one end of the return spring is fixedly connected to the movable plate.

[0014] In some embodiments, one end of the connecting rod located outside the fixing plate is fixedly connected to a pressing plate.

[0015] In some embodiments, the outer side of the end of the insertion rod is chamfered.

[0016] In some embodiments, a plurality of fixing rods are fixedly connected to the inner side of the positioning ring, and the end of each fixing rod is fixedly connected to a limiting hook, and the inner side of the positioning ring is slidably connected to an elastic ring that is engaged with the limiting hook, and an isolation membrane is wrapped around the outer wall of the elastic ring, the inner side of the isolation membrane is fixedly connected to the elastic ring, and the outer side of the isolation membrane is fixedly connected to the protective membrane, and a connecting rope is slidably connected to the inner side of the elastic ring, and the outer wall of the positioning ring is fixedly connected to a guide tube, one end of the connecting rope is fixedly connected to a rope ring, and the other end passes through the guide tube and is fixedly connected to the sealing block, the rope ring is sleeved on the middle part of the connecting rope, and the guide tube opening faces upward, and the top of the guide tube is fixedly connected to a connecting sleeve, and a sealing groove corresponding to the position of the sealing block is provided in the connecting sleeve, and a pull ring is fixedly connected to the top surface of the sealing block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First: This solution uses a pressure spring and a positioning ring to unfold the folding membrane. The protective structure formed by the protective membrane and the folding membrane can effectively prevent moisture from penetrating the puncture point from the outside. Even when the patient washes his hands or performs other activities that may come into contact with water, the puncture point can be kept dry, reducing the possibility of bacterial infection and providing a safer environment for the patient's recovery.

[0019] Secondly, the positioning ring also secures the fixation plate, preventing it from shifting due to patient movement. This ensures the compression head is precisely aligned with the puncture point, preventing compression failure or pressure dispersion due to device deviation. Furthermore, because the pressure spring is located within the folding membrane, the folding membrane also protects the pressure spring from rust.

[0020] Third: The hydrophilic PU film in this solution can effectively block liquid water and prevent external moisture from invading the puncture site. At the same time, it has excellent breathability, thereby preventing the puncture site from accumulating sweat and moisture due to long-term closure, leading to skin moisture, immersion or secondary infection.

[0021] Fourthly, the setting of anti-slip particles can significantly enhance the friction between the protective film and the patient's skin, preventing the device from rotating, slipping or loosening during limb movements, further improving the overall wearing stability. At the same time, combined with the elastic fitting effect of the buffer ring, a continuous and uniform sealing contact surface can be formed around the positioning ring, effectively avoiding gaps caused by local uneven pressure or slight displacements, thereby enhancing waterproof airtightness and preventing external moisture from penetrating into the puncture area along the edge.

[0022] Fifth: After the isolation membrane in this solution is unfolded, it can seal the compression head and achieve sealed isolation of the compression head, thereby preventing the compression head from being contaminated by the patient's blood, body fluids, etc. and causing contamination to the outside world, effectively preventing cross-infection and the spread of biohazards, and significantly improving the safe handling performance of the device after use.

[0023] Sixthly, the sealing mechanism in the present application can be triggered by pulling the pull ring, without the need for additional tools or complex operations, especially suitable for clinical fast-paced environment or non-professional use, the whole process is fast and intuitive, ensuring that the pollution source isolation can be completed in time after each use. At the same time, since the limiting hook cannot be restored after being pulled off, and the elastic ring cannot be reversibly contracted after losing support, the isolation film is permanently unfolded and locked in the closed state, so that the design has the characteristics of preventing misuse and preventing repeated use, eliminating the risk of misuse or malicious repeated use of the device, in line with the safety specifications of disposable medical devices.

[0043] The techniques, methods, and devices known to those skilled in the relevant art can not be discussed in detail, but in appropriate cases, the techniques, methods, and devices should be considered as part of the specification.

[0044] As shown in Figures 1 to 8 An emergency limb pressing hemostasis device, comprising a fixed plate 1 and a pressing head 2 installed at the bottom of the fixed plate 1, an installation plate 5 is installed on the bottom surface of the fixed plate 1, a positioning ring 3 is arranged below the installation plate 5, a plurality of pressure springs 4 are fixedly connected between the positioning ring 3 and the installation plate 5, a protective film 9 is fixedly connected to the outer wall of the positioning ring 3, a folding film 10 is fixedly connected to the top of the protective film 9, and the top of the folding film 10 is fixedly connected to the bottom surface of the installation plate 5. The pressing head 2 is located inside the positioning ring 3, and the pressure spring 4 is located inside the folding film 10.

[0045] The emergency limb pressing hemostasis device in the present application, after the staff uses the knob on the fixed plate 1 to press the pressing head 2 tightly to the puncture site, under the action of the pressure spring 4, the positioning ring 3 will be tightly attached to the patient's skin, at this time the protective film 9 and the folding film 10 will form a closed structure, wrapping the pressing head 2 and the puncture point below it, so as to effectively prevent moisture from entering the puncture point from the outside, even when the patient washes hands or performs other activities that may contact water, the puncture point can remain dry, reducing the possibility of bacterial infection, and providing a safer environment for the patient's recovery. On the other hand, the positioning ring 3 can also provide a fixing effect for the fixed plate 1, preventing the fixed plate 1 from shifting due to patient activity, and since the pressure spring 4 is located inside the folding film 10, the folding film 10 can also prevent the pressure spring 4 from rusting.

[0046] In some embodiments, the installation plate 5 is fixedly connected with adsorption blocks 7 on both sides of the surface, and the bottom surface of the fixed plate 1 is fixedly connected with two magnetic adsorption blocks 8 corresponding to the positions of the adsorption blocks 7. The adsorption blocks 7 and the magnetic adsorption blocks 8 can provide the installation plate 5 with fixing and quick release functions, so as to facilitate the replacement of the protective film 9 when used by different patients and prevent cross infection.

[0047] In some embodiments, the protective film 9 and the folding film 10 are both hydrophilic PU films. The hydrophilic PU film can effectively block liquid water and prevent external moisture from entering the puncture site, while having excellent air permeability, thereby avoiding the accumulation of sweat and moisture at the puncture site due to long-term closure, resulting in skin dampness, immersion or secondary infection.

[0048] In some embodiments, the bottom surface of the positioning ring 3 is fixedly connected with a buffer ring 6, and the buffer ring 6 is wrapped by the protective film 9. The buffer ring 6 is made of sponge or silica gel pad elastic material, which can prevent the positioning ring 3 from excessively pressing the skin of the patient and avoid the gap between the positioning ring 3 and the skin of the patient, which can cause water leakage.

[0049] In some embodiments, the bottom surface of the protective film 9 is fixedly connected with a plurality of anti-skid particles 11. The arrangement of the anti-skid particles 11 can significantly enhance the friction between the protective film 9 and the skin of the patient, prevent the device from rotating, slipping or loosening during limb movement, and further improve the overall wearing stability. At the same time, in cooperation with the elastic fitting effect of the buffer ring 6, a continuous and uniform sealing contact surface can be formed around the positioning ring 3, effectively avoiding the gap caused by uneven local pressure or slight displacement, thereby strengthening the waterproof sealing property and preventing external moisture from penetrating into the puncture area along the edge.

[0050] In some embodiments, the top surface of the positioning ring 3 is fixedly connected with two limiting plates 12, the surface of the installation plate 5 is provided with connecting grooves 13 corresponding to the positions of the limiting plates 12, the bottom surface of the fixed plate 1 is provided with insertion grooves 14 corresponding to the positions of the limiting plates 12, and the two sides of the fixed plate 1 are provided with telescopic grooves 25. Each telescopic groove 25 is slidably connected with a connecting rod 15, one end of the connecting rod 15 located in the fixed plate 1 is fixedly connected with a connecting plate 18, a moving groove 19 corresponding to the position of the connecting plate 18 is formed in the fixed plate 1, the other end of the connecting plate 18 is fixedly connected with an insertion rod 20, a sliding groove 21 corresponding to the position of the insertion rod 20 is formed in the inner wall of the moving groove 19, and the top of the limiting plate 12 is provided with a limiting hole 22 corresponding to the position of the insertion rod 20. The insertion rod 20 can be used to fix the limiting plate 12, thereby fixing the positioning ring 3, preventing the positioning ring 3 from affecting the operation and observation of the user during the adjustment of the compression head 2, and after the compression head 2 is fixed, the user can press the connecting rod 15, so as to separate the insertion rod 20 from the limiting hole 22, thereby enabling the pressure spring 4 to press the positioning ring 3 against the skin of the patient.

[0051] In some embodiments, a movable plate 16 is fixedly connected to the middle portion of the connecting rod 15. A compression groove 17 is defined within the fixed plate 1 corresponding to the position of the movable plate 16. A return spring 23 is fixedly connected within the compression groove 17. One end of the return spring 23 is fixedly connected to the movable plate 16. The return spring 23 ensures the stability of the insertion rod 20 in fixing the limit plate 12, preventing it from loosening during storage or movement.

[0052] In some embodiments, one end of the connecting rod 15 located outside the fixing plate 1 is fixedly connected to a pressing plate 24. The pressing plate 24 can bring convenience to the user in pressing the connecting rod 15.

[0053] In some embodiments, the outer end of the insertion rod 20 is chamfered. The chamfer facilitates insertion of the insertion rod 20 into the limiting hole 22. Even if there is a slight misalignment between the insertion rod 20 and the limiting hole 22, the chamfer can guide the insertion rod 20 to slide smoothly into the hole, achieving a "self-alignment" function, significantly improving assembly efficiency and operational tolerance.

[0054] In some embodiments, a plurality of fixing rods 26 are fixedly connected to the inner side of the positioning ring 3, and the end of each fixing rod 26 is fixedly connected to a limiting hook 27. The inner side of the positioning ring 3 is slidably connected to an elastic ring 28 that is engaged with the limiting hook 27. The outer wall of the elastic ring 28 is wrapped with an isolation membrane 29. The inner side of the isolation membrane 29 is fixedly connected to the elastic ring 28, and the outer side of the isolation membrane 29 is fixedly connected to the protective membrane 9. A connecting rope 30 is slidably connected inside the elastic ring 28. A guide tube 32 is fixedly connected to the outer wall of the positioning ring 3. One end of the connecting rope 30 is fixedly connected to a rope ring 31, and the other end passes through the guide tube 32 and is fixedly connected to the sealing block 33. The rope ring 31 is sleeved on the middle part of the connecting rope 30, and the opening of the guide tube 32 faces upward. A connecting sleeve 36 is fixedly connected to the top of the guide tube 32. A sealing groove 34 corresponding to the position of the sealing block 33 is provided in the connecting sleeve 36, and a pull ring 35 is fixedly connected to the top surface of the sealing block 33.

[0055] Specifically, when the patient has completed hemostasis and no longer needs to use the device, after removing the device, the pull ring 35 can be pulled. At this time, the connecting rope 30 is pulled, and the square rope frame formed between the connecting rope 30 and the rope ring 31 will shrink. At this time, due to the limited strength of the limit hook 27, the limit hook 27 will be broken, thereby causing the elastic ring 28 to shrink, and then the isolation membrane 29 to unfold. When the pull ring 35 is pulled to the limit, the elastic ring 28 is completely contracted, and the isolation membrane 29 is completely unfolded and closes the compression head 2, thereby achieving sealed isolation of the compression head 2, thereby preventing the compression head 2 from being contaminated by the patient's blood, body fluids, etc. and causing pollution to the outside world, effectively preventing cross infection and the spread of biohazards, and significantly improving the safe handling performance of the device after use.

[0056] This sealing mechanism is triggered simply by pulling the pull ring 35, requiring no additional tools or complex operation. It is particularly suitable for fast-paced clinical environments or for use by non-professionals. The entire process is quick and intuitive, ensuring prompt isolation of the contamination source after each use. Furthermore, because the limit hook 27 cannot be restored after being broken, the elastic ring 28 irreversibly contracts after losing its support, permanently expanding the isolation membrane 29 and locking it in a closed state. This design is designed to prevent accidental opening and reuse, eliminating the risk of misuse or malicious reuse of the device and complying with safety regulations for disposable medical devices.

[0057] The opening of the guide tube 32 faces upward, which can prevent the guide tube 32 from contacting the patient's skin, preventing skin discomfort, indentation or local blood circulation obstruction caused by friction or pressure, and effectively reducing the risk of body fluids such as sweat and sebum penetrating into the guide tube 32 through the opening.

[0058] The mutual cooperation between the sealing block 33 and the sealing groove 34 can prevent water from entering the guide tube 32 when the patient wears the device, thereby effectively preventing liquid from penetrating into the internal structure along the connecting rope 30, further enhancing the overall waterproof performance and safety of the device.

[0059] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily devise other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the claims of the present invention.
