Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a film for fixing an infusion port. Background Art

[0002] The intravenous infusion port is a relatively new infusion line technology, referred to as the infusion port. It is mainly for patients who need long-term and repeated infusion of chemotherapy drugs. For long-term infusion, the infusion port can be left in place for 7 days before needing to be re-inserted. It is a fully implantable closed infusion system that is buried in the human body. This system includes a central venous catheter, and the end of the catheter is connected to a device called a puncture seat. The catheter is surgically punctured subcutaneously and placed in a large blood vessel of the human body, such as the subclavian vein and superior vena cava. Part of the catheter is buried in the subcutaneous tissue, and the puncture seat at the other end is left in the subcutaneous tissue of the chest wall and sutured and fixed. During treatment, the needle is positioned here and inserted vertically into the reservoir of the puncture seat through percutaneous puncture, which can facilitate injection, long-term continuous infusion and blood collection, and is suitable for high-concentration chemotherapy drugs, complete parenteral nutrition, and infusion of blood products. During the use of the infusion port, the butterfly needle needs to be punctured into the interior of the infusion port, and then the drug solution is injected into the interior of the upper end of the infusion port through the puncture needle, and then the drug solution is injected into the patient's body through the infusion tube. The infusion port is located under the patient's skin, and the puncture needle is generally tightly connected to the upper end of the infusion port to prevent the puncture needle from accidentally falling off.

[0003] Depending on the surgical site, the infusion port can be placed on the patient's arm or chest. At present, when in use, a special puncture needle (butterfly needle or butterfly wing needle) is usually fixed on the skin with a flat ordinary transparent film as shown in Figure 1 (a). In order to prevent the needle from shaking, a white gauze c is usually placed under the butterfly needle. The gauze is in contact with the skin, as shown in Figure 1 (b). For some tumor patients, they are usually thin, so placing gauze can be raised. In practice, the infusion port is buried in the subcutaneous tissue to form a spherical protrusion, and the gauze and the padding are Butterfly needles all form similar raised structures. The applicant has been engaged in the hospital nursing industry for many years and has found through observation that when fixed with a flat film, the seal on all sides is uneven, the raised structure and nearby areas cannot be completely sealed, the tape will be pulled diagonally, and gaps will exist. After a period of time, especially when the patient is active, the area where the butterfly needle is located is obliquely adhered to the skin, which is easy to tear and warp, and the gap will become larger and larger. After a long time, it is easy to cause air leakage in some parts of the flat film, which can easily destroy the sterile environment and cause infection at the puncture point. Utility Model Content

[0004] The purpose of the present application is to provide a film for fixing an infusion port that is convenient to adhere to and fix with the patient's skin and has good sealing performance.

[0005] The present application provides a film for fixing an infusion port, wherein the film has an adhesive backing surface on the side close to the patient's skin, and two stickers are adhered to the adhesive backing surface. The feature is that the middle portion of the film bulges upward to form a convex accommodating cavity for accommodating the butterfly needle of the infusion port, and the inner surface where the accommodating cavity is located does not form an adhesive backing surface.

[0006] Furthermore, the shape of the accommodating cavity is a groove-shaped rectangular parallelepiped or cube.

[0007] Furthermore, the adhesive backing surface is a hydrocolloid dressing.

[0008] Furthermore, the accommodating cavity has a length of 3 to 3.5 centimeters, a width of 3 to 3.5 centimeters, and a height of 3 to 3.5 centimeters.

[0009] Furthermore, the stickers are separated into three pieces, namely left, middle and right pieces, wherein the stickers on the left and right sides partially overlap with the middle sticker.

[0010] By using a film for fixing an infusion port provided by the present application, the traditional flat transparent film is replaced with a convex accommodating cavity structure formed in the middle. When in use, the accommodating cavity just fits the elevated part where the butterfly needle is located inside, and the other parts of the film are normally bonded and fixed to the patient's skin through a sticky hydrocolloid dressing. This structure avoids the disadvantages of tearing and easy warping caused by the flat connection between the traditional flat film and the part where the butterfly needle is located. The other parts of the film can be well fixed and sealed with the skin, and there is no risk of infection. It also reduces the workload of nurses who need to change the dressing or re-fix the film because the infusion port worn by the patient is loose and not fixed tightly.

[0021] Reference Figure 2-Figure 3 As shown, the embodiment of the present application provides a film for fixing an infusion port. The length and width of the film 1 can be designed to be 15 cm long and 12 cm wide. The film 1 has an adhesive backing on the side close to the patient's skin. Several stickers are adhered to the adhesive backing surface. The stickers are non-stick paper and are easy to tear off from the adhesive backing surface. The stickers are adhered to the adhesive backing surface in advance. When in use, the two stickers are torn off separately, and the adhesive backing surface will be adhered flatly to the patient's skin. The middle part of the film 1 of the present application bulges upward to form a raised accommodating cavity 2 where the butterfly needle of the infusion port is located. The inner surface where the accommodating cavity 2 is located does not form an adhesive backing surface. The accommodating cavity 2 mainly wraps the internal adhesive tape pad layer and the convex structure formed by the butterfly needle, so that the film 1 outside the accommodating cavity 2 can be in flat contact with the skin and fixed. Specifically, as Figure 4As shown, the stickers are separated into three pieces, namely, left, middle and right. The dotted square frame in the figure is the middle sticker 31. The length and width of the middle sticker 31 are greater than the length and width of the accommodating cavity 2. The sticker 31 in the middle mainly covers the accommodating cavity 2 and a small part of the film area on the peripheral side of the accommodating cavity 2. The stickers 32 on the left and right sides mainly cover the film areas on the left and right sides of the film 1, and the stickers 32 on the left and right sides partially overlap with the sticker 31 on the middle side, that is, the right end face of the left sticker 32 and the left end face of the right sticker 32 partially cover the end face of the middle sticker 31, and the covered areas are not adhered, which is convenient for manual tearing. More preferably, the ends of the stickers 32 on the left and right sides just reach the outer edge of the slot where the accommodating cavity 2 in the middle is located. When in use, first tear off the sticker on the middle side, and then according to the location of the infusion port on the patient's arm or chest, align the accommodating cavity 2 with the location and buckle it on the patient's skin. Since the stickers on the left and right sides are not torn off at this time, it is convenient for the nurse to operate with hands without sticking to the hands. Then, tear off the stickers on the left and right sides, so that the adhesive surface is completely exposed, and the film 1 can be completely and flatly attached to the patient's skin without being easily torn.

[0022] In this embodiment, the shape of the accommodating chamber 2 is a groove-shaped rectangular parallelepiped or cube, which is usually larger than the length, width and height of the butterfly needle and the gauze pad layer below it. Preferably, the length is 3 to 3.5 cm, the width is 3 to 3.5 cm, and the height is 3 to 3.5 cm. The length, width and height can adapt to butterfly needles of different sizes. The accommodating chamber 2 is transparent, such as plastic material, which is convenient for viewing the working state of the infusion port inside. A preferred method is that the accommodating chamber is made of elastic material, which is preferably elastic.

[0023] As a preferred embodiment of the utility model, the adhesive backing surface in the present application is a layer of hydrocolloid dressing. Compared with traditional gauze dressings, hydrocolloid dressings can keep wounds moist, create a low-oxygen, slightly acidic environment, reduce allergic reactions in common patients, such as the formation of rashes and blistering, accelerate wound healing, have an autolytic debridement effect, dissolve fibrinogen, and have a faster absorption rate.

[0024] The present application improves the conventional planar film 1 by designing a protruding receiving cavity 2 in the middle part thereof, which just fits the butterfly needle 4 and the raised part formed below it. Figure 5 As shown, the other parts of the film 1 are normally fixed to the patient's skin by flatly bonding with a sticky hydrocolloid dressing. This structure avoids the disadvantages of tearing and easy warping caused by the flat connection between the traditional flat film and the part where the butterfly needle 4 is located. The other parts of the film can be well fixed and sealed with the skin, and there is no risk of infection. It also reduces the workload of nurses who need to change the dressing or re-fix the film because the infusion port worn by the patient is loose and not fixed tightly.

[0025] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
