[0001] This invention belongs to the technical field of medical devices, specifically relating to a hemostatic fixation device for blood collection. Background Technology
[0002] Blood collection is a common procedure in medical diagnosis. Traditional blood collection methods usually require medical staff to prepare adhesive tape, manually fix the lancet, and manually apply pressure to stop the bleeding after collection. This method has the following problems: hemostasis depends on manual pressure from medical staff, resulting in uneven pressure, poor hemostasis, and a tendency to cause local skin bruising or subcutaneous hematoma. It is also inconvenient, cumbersome, increases the workload of medical staff, and reduces work efficiency.
[0003] Therefore, we designed a hemostatic fixation device for blood collection that can solve the above problems. Summary of the Invention

[0018] 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. Specific Implementation Example 1: As attached Figure 1-3 As shown in this embodiment, a hemostatic fixation device for blood collection is characterized in that: the fixation component 1 includes a connecting strap 11 and a fixation strap 12 movably connected to the connecting strap 11; The fixing component 1 is used to fix the hemostatic component 2 to the blood collection site, and the connecting strap 11 and fixing strap 12 are used to surround and fix around the patient's blood collection site, playing a role in initial positioning and support.
[0020] The hemostatic component 2 is disposed between the connecting strap 11 and the fixing strap 12, and includes a housing 21 disposed between the connecting strap 11 and the fixing strap 12, a power component 22 that passes through the top of the housing 21 and is movably connected to the top of the housing 21, an adjusting component 23 disposed inside the housing 21 and fixedly connected to the end of the power component 22, a positioning component 24 disposed inside the housing 21 and sleeved in the middle of the adjusting component 23, and a pressing pad 25 disposed at the end of the adjusting component 23.
[0021] The outer casing 21 is positioned between the connecting strap 11 and the fixing strap 12, protecting and supporting the internal components. After blood collection, a hemostatic patch is applied to the blood collection site, with medical adhesive tape on both sides. The adjusting component 23 is driven by the rotating power component 22, adjusting the position of the pressure pad 25 and driving the positioning component 24. The adjusting component 23 adjusts the height of the pressure pad 25, which presses downwards onto the blood collection site through the hemostatic patch, achieving hemostasis. During the movement of the adjusting component 23, the positioning component 24 operates, pressing the adhesive areas on both sides of the hemostatic patch, allowing it to better adhere to the wound after blood collection, protecting the wound. A replaceable disposable hemostatic patch is provided to prevent contamination of the pressure pad 25, allowing for reuse and reducing costs. The hemostatic patch includes a sponge layer and adhesive layers on both sides. Specific Implementation Example 2: As attached Figure 1-6 As shown, in this embodiment, the power component 22 includes a power rod 221 that is threadedly connected to the top of the housing 21, and a knob 222 disposed on the top of the power rod 221.
[0023] The knob 222 has anti-slip texture on its outer side. Rotating the knob 222 drives the power rod 221 to rotate. The top of the outer casing 21 has a slot, and the power rod 221 is threaded into the slot. The top of the power rod 221 is connected to the knob 222, and the bottom is fixedly connected to the adjusting shaft 231 of the adjusting component 23. When medical staff rotate the knob 222, the power rod 221 moves up and down vertically through the threaded transmission, thereby converting the rotational motion into linear motion and driving the movement of the adjusting component 23.
[0024] The adjusting component 23 includes an adjusting shaft 231 fixedly installed at the bottom end of the power rod 221, an inclined groove 232 installed on the adjusting shaft 231, a positioning rod 233 movably installed in the inclined groove 232, and a pressing rod 234 movably installed inside the adjusting shaft 231 and fixedly connected to the positioning rod 233.
[0025] When the power rod 221 rotates, it drives the adjusting shaft 231 to rotate. The rotation of the adjusting shaft 231 drives the inclined groove 232 on the adjusting shaft 231 to rotate, thereby driving the positioning rod 233 in the inclined groove 232 to move. The positioning rod 233 moves along the inclined groove 232, thereby driving the pressing rod 234 to move up and down, thus controlling the pressing and releasing of the pressing pad 232, and playing a role in pressing and stopping bleeding at the blood collection site.
[0026] The positioning component 24 includes a positioning ring 241 with the bottom end of the adjusting shaft 231 fixedly sleeved on the outside of the pressing rod 234, a positioning plate 242 with the bottom end of the positioning ring 241 and slidably connected to the inner wall of the outer shell 21, four connecting seats 243 on both sides of the bottom end of the positioning plate 242, a rotating rod 244 rotatably mounted on the connecting seats 243, and a pressing wheel 245 movably mounted at the end of the rotating rod 244.
[0027] The positioning ring 241 is used to fix the pressure rod 234 on the outside, serving as a support and guide. When the pressure rod 234 moves downward, it drives the positioning ring 241 downward. When the positioning ring 241 moves downward, it drives the positioning plate 242 downward, causing the rotating rod 244 connected to the positioning plate 242 to rotate and slide from the inside to both sides. During the sliding process, the pressure roller 245 will roll over the adhesive layer on both sides of the bandage, better fixing the bandage. When the positioning plate 242 moves downward, because the top of the pressure rod 234 is rotatably connected to the connecting seat 243, and the connecting seat 243 is equipped with a baffle, the pressure rod 234 can only rotate to both sides. Therefore, during the rotation, the pressure roller 245 will roll from the middle of the adhesive layer to both sides for fixation. Specific Implementation Example 3: As attached Figure 1-6 As shown, in this embodiment, a pressing rod 234 is movably inserted through the center of the positioning plate 242. The center of the positioning plate 242 has a circular hole, within which the pressing rod 234 is movably disposed.
[0029] Four rotating rods 244 are provided, with the rotating rods 244 located on the same side and positioned near the center of the positioning plate 242. The rotating rods 244 are located on both sides of the blood collection site, respectively on the adhesive layer of the hemostatic patch, driving the pressing roller 245 to roll laterally across the patient's arm. They are all located in the middle of the adhesive layer, which helps to better fix the hemostatic patch.
[0030] A groove 3 is provided on both sides of the inner wall of the outer shell 21, and a connecting rod 31 connected to both sides of the positioning plate 242 is slidably disposed in the groove 3.
[0031] The slide grooves 3 are provided on both sides of the inner wall of the housing 21 to guide and restrict the movement of the positioning plate 242, ensuring that it slides smoothly in the vertical direction and avoiding deviation.
[0032] The pressure pad 25 is fixedly mounted on the end of the pressure rod 234. The pressure pad 25 is installed on the end of the pressure rod 234 via a fixed connection, ensuring that it can move synchronously with the movement of the pressure rod 234, thereby realizing the pressing and releasing operation of the blood collection site. The pressure pad 25 is usually made of a soft and elastic material, such as medical sponge or silicone, which can provide uniform and continuous pressure while avoiding excessive pressure or damage to the skin. The shape of the pressure pad 25 is usually circular or oval to better conform to the skin around the needle hole and ensure even distribution of pressure. The pressure pad 25 is used to stop bleeding at the blood collection site through the hemostatic patch, which avoids contamination of the pressure pad 25. Specific Implementation Example 4: As attached Figure 1-6 As shown, in this embodiment, the end of the connecting strap 11 and the end of the fixing strap 12 are connected by Velcro.
[0034] The ends of the connecting strap 11 and the fixing strap 12 are connected by Velcro. This connection method facilitates quick fixation and adjustment of tightness, ensuring that the device can be firmly fixed to the patient's arm or other blood collection sites.
[0035] The bottom of the outer shell 21 is designed to fit the arc shape of the arm.
[0036] The bottom of the outer shell 21 is designed to be curved, which can better fit the natural curve of the patient's arm, reduce pressure on the skin, and improve the patient's comfort.
[0037] Working principle explanation: In use, the hemostatic component 2 is fixed to the blood collection site via the connecting strap 11 and the fixing strap 12. The hemostatic component 2 consists of a housing 21, a power component 22, an adjusting component 23, a positioning component 24, and a pressing pad 25. The power component 22 drives the power rod 221 to move up and down by rotating the knob 222, which in turn drives the adjusting component 23 to move. The adjusting component 23 controls the up and down movement of the pressing rod 234 through the cooperation of the inclined groove 232 and the positioning rod 233, so that the pressing pad 25 can press and stop bleeding at the blood collection site. The positioning component 24 ensures the stable movement of the pressing pad 25 and fixes the hemostatic patch through the positioning ring 241, the positioning plate 242, and the pressing wheel 245. The arc-shaped bottom end of the housing 21 and the Velcro connection further improve the comfort and fixation effect of the device.
