Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a simple, longitudinally-patterned pressure-activated hemostatic patch. Background Technology
[0002] After intravenous infusion or blood draw, a slanted needle mark will remain on the patient's body. This slanted needle mark penetrates the skin and blood vessel. The longitudinal pressure hemostasis method involves placing a cotton swab along the direction of the blood vessel after the intravenous infusion or blood draw, and then pressing the tip of the cotton swab with your finger. The cotton swab compresses the needle mark on the skin and blood vessel to stop the blood flow and stop the bleeding. The process of applying pressure to stop the bleeding requires the patient or their companion to apply pressure continuously for 5 to 10 minutes. However, in actual practice, because patients and their companions are not professional enough, they are prone to not applying enough pressure or applying pressure for too short a time. This can lead to the needle mark causing continuous bleeding and bruising, posing a safety hazard. If the patient is in a hurry to relieve themselves, put on their clothes, or tidy up their belongings, applying pressure to the needle mark can also cause serious inconvenience. Utility Model Content
[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a simple, longitudinally pressed hemostatic patch that can avoid the safety hazards of continuous bleeding and bruising at the needle hole due to insufficient or short pressing time. It can also free the hands of patients or medical staff to continuously press the needle hole, making it more convenient to use.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A simple, longitudinally applied pressure-activated hemostatic patch includes a waterproof patch, a release paper positioned opposite the waterproof patch, and a sponge pad positioned between the waterproof patch and the release paper; the sponge pad includes a circular skin compression portion, and a vascular compression portion is provided radially outwardly on one side of the circular skin compression portion.
[0006] Furthermore, the waterproof patch is circular in shape, and the circular skin compression portion is located at the center of the circular patch.
[0007] Furthermore, one side of the circular patch extends radially outward to form a tail.
[0008] Furthermore, the direction of the blood vessel compression section is offset from that of the tail section.
[0009] Furthermore, the waterproof patch is provided with a pressing mark, which is positioned directly opposite the circular skin compression part and the blood vessel compression part.
[0010] Furthermore, the thickness of the sponge pad ranges from 2 to 3 mm, and the thickness of the waterproof tape ranges from 0.8 to 1 mm.
[0011] Furthermore, the waterproof tape includes a waterproof base layer, an adhesive layer disposed on one side of the waterproof base layer, and the sponge pad is fixedly adhered to the adhesive layer.
[0012] The beneficial effects of this utility model are:
[0013] In practical applications, when using this product, simply peel off the release paper, align the skin compression part with the needle hole on the skin, and align the blood vessel compression part along the blood vessel with the needle hole on the blood vessel. Press the sponge pad onto the skin, and then attach the waterproof patch to the skin. After the waterproof patch is attached, squeeze the needle hole on the skin using the skin compression part and the needle hole on the blood vessel using the blood vessel compression part. This frees up the hands of the patient or medical staff, making it convenient to use. This invention avoids the safety hazards of continuous bleeding and bruising from needle holes due to insufficient or short-duration pressure, and frees up the hands of the patient or medical staff to continuously press the needle hole, making it more convenient to use.

[0016] Figure reference numerals: Waterproof sticker 1; Tail 100; Waterproof base layer 101; Adhesive layer 102; Release paper 2; Sponge pad 3; Circular skin compression part 301; Blood vessel compression part 302; Press mark 4. Detailed Implementation
[0017] like Figure 1 and Figure 2 As shown, a simple, longitudinally arranged pressure-sensitive hemostatic patch includes a waterproof patch 1, a release paper 2 positioned opposite the waterproof patch 1, and a sponge pad 3 positioned between the waterproof patch 1 and the release paper 2; the sponge pad 3 includes a circular skin compression portion 301, and a vascular compression portion 302 is provided radially outward on one side of the circular skin compression portion 301.
[0018] In use, peel off the release paper 2, align the skin compression part with the needle hole on the skin, and align the blood vessel compression part 302 with the needle hole on the blood vessel along the blood vessel direction. Press the sponge pad 3 onto the skin, and then attach the waterproof patch 1 to the skin. After the waterproof patch 1 is attached, squeeze the needle hole on the skin with the skin compression part and squeeze the needle hole on the blood vessel with the blood vessel compression part 302. This frees up the hands of the patient or medical staff and is convenient to use. This utility model can avoid the safety hazards of continuous bleeding and bruising from the needle hole due to insufficient pressure or short pressure time, and it can also free up the hands of the patient or medical staff to continuously press the needle hole, making it more convenient to use.
[0019] like Figure 1 and Figure 2 As shown, the waterproof patch 1 is circular in shape, and the circular skin compression part 301 is disposed at the center of the circular patch. In this embodiment, by disposing the circular skin compression part 301 at the center of the circular patch, the waterproof patch 1 around the circular skin compression part 301 can better maintain the compression effect of the circular skin compression part 301 after it is bonded.
[0020] like Figure 1 and Figure 2 As shown, one side of the circular sticker extends radially outward to form a tail 100; in this embodiment, the tail 100 makes it easier to peel the release paper 2 off the waterproof sticker 1.
[0021] like Figure 1 and Figure 2 As shown, the direction of the blood vessel squeezing part 302 is offset from that of the tail 100. In this embodiment, when the direction of the blood vessel squeezing part 302 is offset from that of the tail 100, medical personnel are less likely to damage the blood vessel squeezing part 302 when tearing off the release paper 2.
[0022] like Figure 1 and Figure 2 As shown, the waterproof patch 1 is provided with a pressing mark 4, which is positioned directly opposite the circular skin compression part 301 and the blood vessel compression part 302. In this embodiment, the pressing mark 4 allows medical personnel to visually see the positions of the circular skin compression part 301 and the blood vessel compression part 302 from the waterproof patch 1, making it more convenient to use.
[0023] like Figure 1 and Figure 2 As shown, the thickness of the sponge pad 3 ranges from 2 to 3 mm, and the thickness of the waterproof patch 1 ranges from 0.8 to 1 mm. In this embodiment, when the thickness of the sponge pad 3 is 2 to 3 mm and the thickness of the waterproof patch 1 is 0.8 to 1 mm, pressing the sponge pad 3 has the best hemostatic effect.
[0024] like Figure 1 and Figure 2 As shown, the waterproof tape 1 includes a waterproof base layer 101, an adhesive layer 102 disposed on one side of the waterproof base layer 101, and a sponge pad 3 fixedly bonded to the adhesive layer 102. In this embodiment, the waterproof base layer 101 is made adhesive by the adhesive layer 102, the sponge pad 3 is fixed to the adhesive layer 102, and the release paper 2 is bonded to the adhesive.
[0025] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
