Description

Technical Field

[0001] The utility model relates to the technical field of hemostatic patches, in particular to a hemostatic patch for blood collection. Background Art

[0002] At present, venous blood sampling is an important method to assist in disease diagnosis. After the blood is drawn from the patient at the blood collection window of the hospital laboratory department and the blood collection window of the physical examination center, the patient needs to press the puncture point with a cotton swab by himself. Generally, it takes 3 to 5 minutes to stop the bleeding by pressing. This traditional method of blood collection and hemostasis prevents the patient's hands from moving freely and requires the patient to maintain a pressing posture. However, in reality, many patients either press the cotton swab incorrectly or do not press well after blood is drawn. After pressing for a short time, the cotton swab is discarded, resulting in bleeding again due to offset of the pressing position or insufficient pressing time, or subcutaneous bruising. At the same time, the patient cannot ensure the cleanliness of the puncture site during the self-pressing process, which is prone to infection. Therefore, it is necessary to design a hemostatic patch for blood collection. Utility Model Content

[0007] By adopting the above technical scheme, the hemostatic cotton is pressed against the needle eye after blood drawing, and the two adhesive tapes are stretched and pasted on the patient's arm. The pressure exerted on the micro airbag presses the hemostatic cotton against the needle eye to prevent bleeding. At the same time, the needle eye generally has an arc. This arc makes the adhesive tape press the two ends of the plastic hard sheet and cooperate with the micro airbag to press the hemostatic cotton against the needle eye. The breathable layer can keep air circulating at the needle eye, and the waterproof layer can prevent water stains from entering the needle eye and affecting the healing of the needle eye. This process realizes the process of facilitating hemostasis, improves work efficiency, and thus enhances practicality.

[0008] Preferably, the bottom layer is made of a transparent PU film material.

[0009] By adopting the above technical solution, the area around the needle hole can be observed at any time through the PU film, thereby enhancing practicality.

[0010] Preferably, both adhesive layers are medical elastic tapes.

[0011] By adopting the above technical solution, the medical elastic tape has a stable viscosity and is non-irritating to the skin, thereby enhancing safety.

[0012] Preferably, the breathable layer is made of cotton cloth.

[0013] By adopting the technical solution, the cotton cloth has good air permeability, thereby enhancing practicality.

[0014] Preferably, the waterproof layer is made of PTFE.

[0015] By adopting the above technical solution, PTFE has good waterproof and moisture permeability and good air permeability, thereby enhancing practicality.

[0016] Preferably, both ends of the two adhesive layers are provided with lifting straps.

[0017] By adopting the above technical solution, the adhesive layer can be conveniently removed by pinching the lifting strap, thereby enhancing the convenience of use.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present application provides a hemostatic patch for blood collection, which has the following beneficial effects:

[0020] Press the hemostatic cotton onto the needle eye after blood drawing, stretch and stick the two adhesive tapes onto the patient's arm, and the pressure exerted on the micro airbag presses the hemostatic cotton onto the needle eye to prevent bleeding. Meanwhile, the needle eye generally has an arc, and this arc causes the adhesive tape to press the two ends of the plastic hard sheet, and cooperate with the micro airbag to press the hemostatic cotton onto the needle eye. The breathable layer can keep air circulating at the needle eye, and the waterproof layer can prevent water stains from entering the needle eye and affecting the healing of the needle eye. This process facilitates hemostasis, improves work efficiency, and thus enhances practicality. BRIEF DESCRIPTION OF THE DRAWINGS
