Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disposable intravenous catheter pressure-type sterile transparent film. Background Art

[0002] Central venous catheterization via peripheral venous puncture is to puncture the vein of the peripheral arm with a catheter. The catheter directly reaches the large vein close to the heart to avoid direct contact between chemotherapy drugs and arm veins. In addition, the blood flow rate of the large vein is very fast, which can quickly dilute the chemotherapy drugs and prevent the drugs from irritating the blood vessels. After the venous catheter is punctured, it needs to be fixed. At present, the Chinese patent with the publication (announcement) number CN206621644U discloses a central venous fixation film, including a catheter fixation film hot-rolled and connected to a catheter fixing ring at the center of its adhesive surface. The catheter fixation film is divided into a fixed area and an easy-tear area separated by an easy-tear line. The easy-tear area is torn along the easy-tear line to expose part of the catheter fixing ring; the catheter fixing film is made of a transparent 3M film, and the catheter fixing ring is made of a silicone ring. The catheter fixing ring makes the skin puncture point located inside its ring, the starting point of the easy-tear area is located at the center of the catheter fixing film and covers the central venous catheter, and the central venous catheter is fixed by the catheter fixing ring and the catheter fixing film at the same time.

[0003] Although the above-mentioned central venous fixation film is made of waterproof, breathable and anti-pollution materials, it keeps the central vein dry and sterile, and takes into account the purpose of ensuring good fixation of the central venous catheter, avoiding adverse events such as central venous displacement and tube removal during the film replacement operation, and also reduces the economic burden of patients, the above-mentioned central venous fixation film has a poor hemostatic effect on the central venous catheter puncture point, which is not conducive to the healing of the puncture point wound.

[0032] Among them, one side of the sterile waterproof transparent film sheet 1 has an adhesive layer, and the other side of the sterile waterproof transparent film sheet 1 is a smooth non-stick surface;

[0033] The absorption pad 2 is fixedly mounted on one side of the sterile waterproof transparent film sheet 1 having the adhesive layer, and the absorption pad 2 has a hemostatic liquid coating layer 3 on one side away from the sterile waterproof transparent film sheet 1 .

[0034] The disposable intravenous catheter pressure-type sterile transparent film using the above technical solution is mainly composed of a sterile waterproof transparent film sheet 1 for fixing the disposable intravenous catheter and an absorbent pad 2 immersed in a liquid medicine with a hemostatic function, so that the disposable intravenous catheter pressure-type sterile transparent film can not only fix the disposable intravenous catheter, but also perform compression hemostasis and drug hemostasis on the puncture point of the intravenous catheter, with a good hemostatic effect, which is conducive to the healing of the wound at the puncture point.

[0035] Specifically, in this embodiment, in order to meet the use requirements, the length of the sterile waterproof transparent film sheet 1 is 10-14 cm and the width is 8-12 cm, and the four corners of the sterile waterproof transparent film sheet 1 are all rounded structures.

[0036] Specifically, in this embodiment, in order to reduce production costs, the sterile waterproof transparent film sheet 1 is a sterile waterproof transparent plastic film sheet.

[0037] Specifically, in this embodiment, in order to prevent the adhesive layer from causing allergies in patients, the adhesive layer is formed by coating with a low-allergenic and latex-free adhesive.

[0038] Specifically, in this embodiment, in order to ensure the performance of the absorption pad 2 in absorbing the medicinal solution, the absorption pad 2 is a polyurethane foam pad. In order to meet the usage requirements, the size of the absorption pad 2 is set to 3.5cm*2.0cm*0.6cm, and the four corners of the absorption pad 2 are set to a chamfered structure.

[0039] Specifically, in the present embodiment, in order to further ensure the compressive hemostatic effect of the absorbent pad 2 on the puncture point of the venous catheter, a plurality of equally spaced iron wire shaping strips 5 are embedded inside the absorbent pad 2. In order to prevent the iron wire shaping strips 5 from rusting, a plastic layer is coated on the outside of the iron wire shaping strips 5. The arranged iron wire shaping strips 5 can adjust the shape of the absorbent pad 2 according to the location of the puncture point of the venous catheter, so that the absorbent pad 2 can better fit the skin at the location of the puncture point of the venous catheter, thereby ensuring the compressive hemostatic effect of the absorbent pad 2 on the puncture point of the venous catheter.
