Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to medical hemostasis, in particular to a blood collection patch for venous blood collection. Background Art
[0002] As we all know, venous blood sampling is a method of extracting a certain amount of venous blood through a needle. Most of the superficial veins located on the body surface are used, usually the elbow vein, the back of the hand vein, the inner ankle vein or the femoral vein. Children can draw blood from the external jugular vein. Different types of syringes can be selected according to the amount of blood collected, equipped with corresponding needles. For some special examinations, in order to avoid platelet activation, plastic syringes and siliconized test tubes or plastic test tubes should be used. After venous blood collection, ask the subject to relax his fist, press the needle insertion site with a sterilized cotton swab, quickly pull out the needle, and continue to press the sterilized cotton swab for 3 minutes.
[0003] Traditional venous blood collection patches are mainly used to stick to the needle hole area of the skin to stop bleeding after venous blood collection or intravenous injection. However, the existing blood collection patches have some problems when used, such as poor hemostasis effect, low patient comfort and difficulty in operation for medical staff. Therefore, it is necessary to improve the existing blood collection patches. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-4 A blood collection patch for venous blood collection comprises an adhesive layer 1, an isolation layer 2, a water-absorbing pad layer 3 and a drug-releasing layer 4, wherein the isolation layer 2 is arranged on the top of the adhesive layer 1, the water-absorbing pad layer 3 is arranged on the top of the isolation layer 2, the drug-releasing layer 4 is arranged on the top of the water-absorbing pad layer 3, a positioning strip 5 is installed on one side of the top of the adhesive layer 1, the positioning strip 5 is located on the top of the adhesive layer 1 and extends to the outside of the adhesive layer 1, an outer peeling layer 6 is arranged on the outer surface of the adhesive layer 1, an easy-pull strip 7 is installed on one side of the outer peeling layer 6, and the easy-pull strip 7 is opposite to the positioning strip 5. In this embodiment, the adhesive layer 1, the isolation layer 2, the water-absorbing pad layer 3 and the drug-releasing layer 4 are arranged in a preset order. They are stacked together to form the main structure of the blood collection patch, and the blood collection patch is sterilized to ensure its sterile state. After venous blood collection or intravenous injection, the pull-tab 7 is manually pulled open, and the pull-tab 7 drives the outer peeling layer 6 to quickly separate from the blood collection patch. Then the drug release layer 4 on the blood collection patch is aligned with the pinhole site and attached to the skin. Medical staff can quickly complete the attachment operation to make the adhesion layer 1 fit closely to the skin. As time goes by, the drug release layer 4 stops bleeding at the pinhole site. The pressing operation can improve the hemostasis efficiency and reduce the bleeding time. When the blood collection patch needs to be removed, the positioning strip 5 is manually pulled, and the positioning strip 5 can easily drive the adhesion layer 1 on the blood collection patch to quickly separate from the skin, thereby improving the operating efficiency.
[0028] In actual use, in order to further reduce skin irritation and allergic reactions, in this embodiment, the adhesive layer 1 adopts medical-grade traceless glue to reduce skin irritation and allergic reactions.
[0029] In actual use, in order to further improve the patient's comfort, in this embodiment, the isolation layer 2 is made of a material with good air permeability to ensure normal breathing of the skin.
[0030] In actual use, in order to further prevent blood from spilling out, in this embodiment, the water-absorbing pad layer 3 is made of a highly water-absorbent material to quickly absorb blood and prevent blood from spilling out.
[0031] In actual use, the hemostatic effect is further improved. In this embodiment, the drug releasing layer 4 contains hemostatic drugs and antibacterial agents. After the blood collection patch is attached to the skin, the drug releasing layer 4 can slowly release the drug to achieve the effect of rapid hemostasis and infection prevention.
[0032] In actual use, the operation difficulty of medical staff is further reduced. In this embodiment, the adhesion layer 1 is designed in an elliptical shape. The elliptical design can better adapt to the needs of venous blood collection in different parts. Compared with traditional round or square blood collection patches, the elliptical shape can better fit the direction of the vein, allowing medical staff to be more accurate in positioning and reduce repeated operations caused by positioning errors. The elliptical blood collection patch can better adapt to the skin curve and reduce discomfort during attachment. For patients with sensitive skin, this design can also reduce the risk of allergies and irritation.
[0033] Preferably, in this embodiment, the water-absorbing pad layer 3 and the drug-releasing layer 4 are both arranged at the center of the isolation layer 2 to facilitate the positioning of the hemostasis point.
[0034] Preferably, in this embodiment, the easy-pull strip 7 and the positioning strip 5 are designed to be the same in shape and size, so as to facilitate pulling the easy-pull strip 7 and the positioning strip 5 .
[0035] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings.
