Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a blood collection bandage for use in health checkup centers. Background Technology

[0002] Currently, health checkup centers, as the forefront of population health screening, handle a huge workload of blood collection every day. Post-blood collection hemostasis care at the puncture site is a crucial part of the health checkup process, directly affecting the patient's experience and safety.

[0003] Currently, there are two main methods of hemostasis commonly used in clinical practice: one is the traditional method of applying pressure with cotton swabs / cotton balls and medical tape; the other is the use of commercially available elastic bandages or hemostatic patches. However, in practical applications, existing technologies have the following limitations: 1. Low operational efficiency: Medical examination centers have high patient flow and a fast pace, requiring nurses to quickly complete a series of two-handed operations after needle removal, such as "taking cotton swabs - applying pressure - tearing tape - wrapping and fixing." This is not only time-consuming, but also prone to problems such as tape being wrapped too loosely or too tightly, not adhering firmly, or being torn to varying lengths, affecting work efficiency and operational standardization; 2. Difficulty in precisely controlling the pressure effect: Traditional tape relies solely on adhesiveness to fix the cotton ball, making it impossible to quantify the pressure and resulting in uneven application. Insufficient pressure can cause the cotton ball to shift, leading to bleeding at the puncture site and subcutaneous hematoma (commonly known as a "bulge"), increasing patient pain and the risk of disputes. Excessive pressure may affect blood circulation in distal limbs, causing patients to complain of numbness and discomfort, and even requiring secondary adjustments by nurses. 3. Poor patient experience: The medical tape used for fixation is often very sticky, easily sticking to hair when patients remove it themselves, causing significant pain during the tearing process, and even causing skin redness and allergies. In addition, the exposed tape and cotton ball are unsightly and may cause psychological embarrassment to patients in public places. 4. Lack of standardized and integrated design: Existing solutions are mostly separate components (cotton swabs + tape), lacking a dedicated design that organically integrates the functions of "compression" and "fixation". Differences in the operating techniques of different nurses also lead to inconsistent hemostatic effects and patient comfort, making it difficult to achieve homogenized nursing care. Summary of the Invention

It can be quickly placed at the puncture site, significantly shortening the treatment time for individual patients and effectively coping with the blood collection pressure during peak medical examination periods.

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1 and Figure 2A blood collection bandage for use in a health checkup center requires a sterile sponge pad to be placed between the puncture site and the elastic airbag 27 before applying pressure to the puncture site to ensure absorption of bleeding from the puncture site.

[0018] For instructions on how to achieve a strap-on, quick-wearing setup, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 An elastic binding mechanism 1 needs to be set up, the structure of which includes a polyurethane foam band 11 that can wrap around the puncture point and a first elastic band 13 and a second elastic band 14 that can elastically bind the patient's limb. The elastic airbag 27 is aligned with the puncture point. Then, the first elastic band 13 and the second elastic band 14 are wrapped around the limb. Finally, they are fixed by the hook side 15 and the loop side 16 of Velcro, thereby realizing the binding-type quick wear. The first elastic band 13 and the second elastic band 14 have an elastic contraction function, thereby generating a contraction-type fixation for the patient's limb to ensure the stability of the device during operation.

[0019] For details regarding the specific structure of the elastic binding mechanism 1, please refer to [link / reference]. Figure 3 It also includes a component mounting port 12 located at the center of the polyurethane foam strip 11 and having open structures at both ends. The two ends of the polyurethane foam strip 11 are respectively embedded with a first elastic band 13 and a second elastic band 14. The first elastic band 13 has a hook and loop fastener 15 on its upper surface at the end away from the polyurethane foam strip 11, and the second elastic band 14 has a hook and loop fastener 16 on its lower surface at the end away from the polyurethane foam strip 11. The first elastic band 13 and the second elastic band 14 are made of textile material with elastic extensibility. The hook and loop fastener 15 and the hook and loop fastener 16 are adapted to each other to form an adhesive effect.

[0020] To achieve adjustable pressure application at the puncture site, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6A buffer compression mechanism 2 needs to be set up. Its structure includes a hollow cylinder 21 installed in the middle of the polyurethane foam belt 11 and having a hollow internal structure; an elastic airbag 27 embedded in the bottom of the hollow cylinder 21 and capable of compressing the puncture point under pressure; a piston plate 28 placed inside the hollow cylinder 21 and capable of indirectly pressurizing the elastic airbag 27; and an externally threaded rod 210 capable of changing the position of the piston plate 28. By rotating the knob cap 212 in a directional manner, due to the threaded connection, the rotation of the externally threaded rod 210 will produce longitudinal movement, causing it to drive the piston plate 28 to move downward. At this time, the pressure of the buffer solution located below the piston plate 28 increases. This pressure will cause the elastic airbag 27 to expand downward until the elastic airbag 27 generates the required pressure on the sterile sponge and the patient's puncture point, thereby realizing the adjustable pressure function of the puncture point.

[0021] For details regarding the specific structure of the buffer-type compression mechanism 2, please refer to [link / reference]. Figure 4 , Figure 5 and Figure 6 It also includes a component movable cavity 22 disposed inside the hollow cylindrical body 21. The bottom of the hollow cylindrical body 21 is provided with an upwardly concave liquid compression cavity 25. The top of the liquid compression cavity 25 and the bottom of the component movable cavity 22 are provided with liquid flow holes 26. The hollow cylindrical body 21 has a first annular embedding groove 23 on its outer circumferential surface near its bottom end, and the first annular embedding groove 23 is embedded around the component mounting port 12. The bottom periphery of the hollow cylindrical body 21 is provided with a second annular embedding groove 24 for embedding the opening end of the elastic airbag 27. The top of the hollow cylindrical body 21 is provided with an internally threaded hole 29 communicating with the top of the component movable cavity 22. A piston plate 28 capable of moving along its axial direction is placed inside the component movable cavity 22. The rod of the externally threaded rod 210 passes through… The threaded structure is installed in the internal threaded hole 29. The bottom rod of the external threaded rod 210 is mounted on the top of the piston plate 28 via a bearing. A helical spring 211 is sleeved around the rod of the external threaded rod 210 located between the piston plate 28 and the top of the component movable cavity 22. A knob cap 212 is provided at the top of the external threaded rod 210. The threaded structure includes an external thread structure on the rod of the external threaded rod 210 and an internal thread structure on the inner circumference of the internal threaded hole 29. The internal thread structure matches the external thread structure. The initial length of the helical spring 211 is greater than the depth of the component movable cavity 22. The closed area formed by the elastic airbag 27, the liquid compression chamber 25, the liquid flow hole 26, the component movable cavity 22, and the piston plate 28 is filled with buffer solution.

[0022] Before applying pressure to the puncture site, a sterile sponge pad should be placed between the puncture site and the elastic balloon 27 to ensure absorption of bleeding. The elastic balloon 27 should be positioned directly over the puncture site. Then, the first elastic band 13 and the second elastic band 14 should be wrapped around the limb. Finally, they should be secured by the hook and loop sides 15 and 16 of the Velcro, achieving a quick and easy binding method. The first elastic band 13 and the second elastic band 14 have elastic contraction function, which provides contraction-type fixation for the patient's limb. Rotating the knob cap 212 causes the threaded rod 210 to move longitudinally due to the threaded connection, which in turn moves the piston plate 28 downward. At this time, the pressure of the buffer solution below the piston plate 28 increases, causing the elastic balloon 27 to expand downward until it exerts the required pressure on the sterile sponge and the patient's puncture site.
