Embodiment 1

[0032] Such as Figure 1-2 As shown, in this embodiment, a U-shaped hemostatic patch has a length of 66 mm and a width of 40 mm. The hemostatic patch includes four layers from top to bottom, which are: the upper layer of the hemostatic patch body 1, the lower layer of the hemostatic patch body 1 and the lower layer of the hemostatic pad 2 , the V-shaped release paper 3 with the lower layer of the hemostatic pad 2 adhered to the main body of the hemostatic patch and the bottom release paper 4 with the lower layer of the V-shaped release paper 3 adhered to the main body of the hemostatic patch, the main body of the hemostatic patch 1 includes an S-shaped cut release paper on the top surface and an adhesive layer on the bottom that is in direct contact with the skin. The end of the hemostatic patch body 1 away from the needle is designed in an arc shape, which is easy to stick the hemostatic patch to the skin firmly to avoid warping. The radius of the arc can be determined accord...

Embodiment 2

[0037] The structural features of the U-shaped hemostatic patch of this embodiment are basically the same as those of Embodiment 1, the difference being that: Figure 4 As shown, the arc radius at the bottom of the U-shaped groove 11 at the U-shaped end of the hemostatic patch body is larger than the arc radius at the top of the first side wing 12 and the second side wing 13. This structure is mainly used when the size of the hemostatic patch is small, so as to avoid The size of the inner U-shaped groove is too small, which makes it inconvenient to pull out the needle.

Embodiment 3

[0039] The structural features of the U-shaped hemostatic patch of this embodiment are basically the same as those of Embodiment 1, the difference being that: Figure 5 As shown, the arc radius at the bottom of the U-shaped groove 11 at the U-shaped end of the hemostatic patch body is smaller than the arc radius at the top of the first side wing 12 and the second side wing 13. The size of the inner U-shaped groove is too large, which leads to the weak sticking of the hemostatic patch.

Abstract

The invention discloses a U-shaped blood stopping patch and a using method thereof. The U-shaped blood stopping patch is used for blood stopping after blood sampling in medical institutions or blood stations and comprises four layers, namely a blood stopping patch body, a blood stopping pad, V-shaped released paper and bottom layer released paper, wherein one end of the blood stopping patch body is a U-shaped end, a U-shaped groove is formed in the U-shaped end, and a first side wing and a second side wing are symmetrically arranged at the two sides of the U-shaped groove. When using the blood stopping patch to withdraw a needle, the needle can be directly drew out through placing fingers at the middle position of a U-shaped opening, the using process is simple and convenient, and an infection caused by the hand or air being in contact with a needle eye is also avoided, and meanwhile, the needle head (handle) is separated from a stickup layer, so that the needle head cannot be stuck.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and in particular relates to a U-shaped hemostatic patch and its application method. Background technique [0002] At present, various medical institutions or blood stations often use simple hemostatic plasters or band-aids for hemostasis after blood collection. The existing problems are: the structure is mostly square or rectangular, and the corners are easy to warp and fall off; Material adhesion affects the speed of needle withdrawal and sticking effect; when the needle is pulled out, air or bacteria on the hand can easily contact the wound and cause infection; the adhesive material is ordinary tape, which cannot be breathable and waterproof. Chinese patent (Application No. 201010273292.8) discloses a "new type of blood collection sticker". Problems such as protruding under the PU film, adhesion of the needle (handle) to the adhesive material, and poor tearing and pasting in the late...
