Description

Technical Field

[0001] This utility model relates to the medical field, specifically to the film for infusion ports. Background Technology

[0002] An infusion port (also known as an implantable intravenous drug delivery system, Port, etc.) is a fully implantable, closed infusion system embedded in the human body. It consists of a catheter tip located in the superior vena cava and an injection port implanted under the skin. Through a minor surgical procedure, the catheter is inserted percutaneously into a major vein, such as the subclavian or superior vena cava. Part of the catheter is embedded in the subcutaneous tissue, while the other end, the injection port, is left in the subcutaneous tissue of the chest wall and sutured in place. After surgery, only a small suture wound is visible on the skin. After healing and suture removal, a protruding ball can be felt on the patient's skin. During treatment, a needle is inserted percutaneously and vertically into the reservoir of the injection port. This allows for convenient injection, long-term continuous infusion, and blood collection. It is suitable for the infusion of high-concentration chemotherapy drugs, total parenteral nutrition, and blood products.

[0003] The use of infusion ports avoids the pain of long-term and repeated intravenous punctures for patients, reduces the risk of phlebitis, thrombosis, and infection, and significantly improves patients' quality of life. When using infusion ports for medication administration in clinical practice, medical staff need to insert a non-traumatic needle (also known as a butterfly needle) into the injection port under completely sterile conditions and secure it effectively to prevent slippage and damage to the surrounding skin by the needle wings. Therefore, the dressing on the infusion port is a very important medical auxiliary device in its use.

[0004] However, there are still problems in the design and application of infusion port films. Because the film itself is soft and has an adhesive layer coated on one end, it is necessary to handle it carefully after the release paper is torn off in order to avoid the film itself sticking. Therefore, medical staff need to use their fingers to keep the edge of the film in place at all times, but this can easily come into contact with the adhesive layer of the film, which reduces the stickiness around it and makes it easy to curl up during use. Utility Model Content

[0005] The purpose of this invention is to provide a film for infusion ports to solve the problem mentioned in the background art, where medical staff use their fingers to constantly adjust the edge of the film, which can easily come into contact with the adhesive layer of the film, thus reducing the stickiness of the surrounding area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film for an infusion port, comprising a film body, the inner circumference of which is provided with a hollow, a second adhesive layer is pasted and fixed on the lower end face of the film body, and outer protective isolation components are provided on both sides of the lower end of the second adhesive layer;

[0007] The external protective isolation component includes a first isolation layer, and a second isolation layer is provided at the lower end of the inner side of the first isolation layer. The second isolation layer and the first isolation layer are integrally connected through a first folded part. The second isolation layer is folded to the lower end of the first isolation layer through the first folded part and fits against the lower end surface of the first isolation layer.

[0008] The second isolation layer has a third isolation layer at both ends. The third isolation layer is integrally connected to the second isolation layer through a second folded section. The third isolation layer is folded to the upper end of the film-applying body through the second folded section and is attached to the upper surface of the film-applying body.

[0009] Preferably, a fourth isolation layer is connected to the middle of the outer side of the first isolation layer. The fourth isolation layer is integrally connected to the first isolation layer through a third folded section. The fourth isolation layer is folded to the upper end of the film-applying body through the third folded section and adheres to the upper surface of the film-applying body.

[0010] Preferably, a third adhesive layer is glued and fixed to the inner end of the upper surface of the fourth and third isolation layers, and a second release paper is glued and connected to the upper end of multiple third adhesive layers on each side.

[0011] Preferably, the main body of the adhesive film is provided with an external support component for the infusion port, which includes an external support strip for the infusion port and an external support strip for the non-traumatic needle. Two external support strips for the non-traumatic needle are integrally connected to the two ends of the external support strip for the infusion port. The inner ring of the main body of the adhesive film is fixed to the upper end of the external support strip for the infusion port and the external support strip for the non-traumatic needle of the external support component. The external support component for the infusion port also includes an intermediate sterile protective film, which is fixed to the inner circumference of the upper end of the external support strip for the infusion port and the external support strip for the non-traumatic needle.

[0012] Preferably, a hemispherical inner cavity is formed inside the intermediate sterile protective membrane along the outer support strip of the infusion port, and a semi-cylindrical inner cavity is formed inside the intermediate sterile protective membrane along the outer support strip of the non-damaging needle.

[0013] Preferably, a first adhesive layer is adhered and fixed to the lower end face of the infusion port external support strip and the non-traumatic needle external support strip, and a first release paper is adhered and connected to the lower end of the first adhesive layer.

[0014] Preferably, a third release paper is provided on both sides of the lower end of the film body. The outer part of the third release paper is located at the lower end of the outer protective isolation component, and the inner part of the third release paper is bonded to the lower end of the second adhesive layer. An exposed part is integrally connected to the middle of the outer side of the third release paper along the outer side of the film body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, the ingenious design of the outer protective isolation component allows medical staff to easily peel off the third isolation paper by pressing the position of the outer protective isolation component during the application of the film, without contacting the second adhesive layer, thus achieving effective aseptic fixation of the film to the skin. Moreover, when peeling off the outer protective isolation component, it is not necessary to contact the side close to the second adhesive layer. Instead, the third isolation layer is folded outward to make it nearly parallel to the skin. While maintaining the state of the film itself, the third isolation layer is pulled outward. The other hand smooths out the film body that has been removed from the position of the outer protective isolation component until the outer protective isolation component is completely removed from the film body. This does not easily cause wrinkles in the film body and does not affect the adhesiveness. It solves the problem that medical staff may easily come into contact with the adhesive layer of the film when they constantly tidy up the edge of the film with their fingers, which reduces the adhesion of the surrounding area.

[0017] (2) In this utility model, the hemispherical inner cavity is aligned with the infusion port, and the film is temporarily fixed to the patient's skin through the first adhesive layer; while using the first adhesive layer to adhere, the fingertips are used to press the outer support strip of the infusion port and the outer support strip of the non-traumatic needle to make the outer support strip of the infusion port and the non-traumatic needle conform as closely as possible to the shape of the infusion port, the non-traumatic needle, and the outer tubing. This provides external support for this part, achieving precise fitting and effective protection of the infusion port and the non-traumatic needle, and significantly improving the stability and sterility of the film.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Please see Figure 1-8 One embodiment provided by this utility model:

[0029] (1) The main body 9 of the adhesive film and the hollow design: The inner circumference of the main body 9 of the adhesive film is hollowed out to accommodate the shape of the infusion port and the non-traumatic needle. A second adhesive layer 10 is attached and fixed to the lower end face for adhesion to the skin, ensuring that the adhesive film fits tightly to the skin and improving stability.

[0030] (2) External protective isolation component 11: Located on both sides of the lower end of the second adhesive layer 10; including a first isolation layer 12, a second isolation layer 14, a third isolation layer 16, a fourth isolation layer 18, and corresponding folded sections. The lower end of the inner side of the first isolation layer 12 is provided with the second isolation layer 14, and the two are integrally connected by the first folded section 13 and can be folded to a fitted state. The two ends of the second isolation layer 14 are provided with the third isolation layer 16, which are integrally connected by the second folded section 15 and can be folded to the upper end of the film body 9 for adhesion. This protects the film body 9 from contamination when the second adhesive layer 10 is adhered to before the lower isolation structure is removed, and also facilitates the removal and fixation of the film by medical personnel. The fourth isolation layer 18 is located in the middle of the outer side of the first isolation layer 12. The fourth isolation layer 18 is integrally connected to the first isolation layer 12 by the third folded section 17 and can be folded to the upper end of the film body 9 for adhesion.

[0031] The upper inner surfaces of the fourth isolation layer 18 and the third isolation layer 16 are glued with a third adhesive layer 19, which is used to attach the second isolation paper 20, further protecting the cleanliness of the film body 9 before use, and making it easier for medical staff to peel off the isolation paper to apply the film.

[0032] Furthermore, the presence of the third isolation layer 16 allows the outer protective isolation component 11 to be pulled outward while the film body 9 remains in its own state, eliminating the need to tear off the outer protective isolation component 11 from the inside. This avoids wrinkles or self-adhesion of the film body 9 when it is torn off in advance and then pasted onto the skin.

[0033] (3) External support assembly 1 for infusion port: including external support strip 2 for infusion port, external support strip 3 for non-traumatic needle, and intermediate sterile protective membrane 4. External support strip 2 for infusion port and external support strip 3 for non-traumatic needle are integrally connected to form a support structure for infusion port and non-traumatic needle. The intermediate sterile protective membrane 4 is fixed to the inner circumference of the upper end of the support strip, forming a hemispherical inner cavity 5 and a semi-cylindrical inner cavity 6, which precisely fit the shape of infusion port and non-traumatic needle, providing effective sterile protection.

[0034] A first adhesive layer 7 is adhered and fixed to the lower end face of the infusion port external support strip 2 and the non-traumatic needle external support strip 3 for initial fixation of the dressing to the skin. A first release paper 8 is adhered and connected to the lower end of the first adhesive layer 7 to protect the first adhesive layer 7 from contamination before dressing application. This facilitates the initial fixation of the dressing by medical staff and protects the adhesiveness of the first adhesive layer 7.

[0035] (4) Third isolation paper 21 and exposed portion 22: Third isolation paper 21 is provided on both sides of the lower end of the film body 9 to protect the second adhesive layer 10. The outer part of the third isolation paper 21 is located at the lower end of the outer protective isolation component 11, and the inner part is bonded to the lower end of the second adhesive layer 10. An exposed portion 22 is integrally connected to the outer middle of the outer side of the third isolation paper 21 along the outer side of the film body 9, which is convenient for medical personnel to peel off. While protecting the second adhesive layer 10, it provides a convenient way to peel off, ensuring effective aseptic fixation of the film to the skin.

[0036] Working principle: Tear off the first isolation paper 8, align the hemispherical inner cavity 5 with the infusion port, and temporarily fix the film to the patient's skin through the first adhesive layer 7; while using the first adhesive layer 7 to adhere, press the infusion port external support strip 2 and the non-traumatic needle external support strip 3 with your fingertips to make the infusion port external support strip 2 and the non-traumatic needle external support strip 3 fit the shape of the infusion port, the non-traumatic needle and the external tube as closely as possible.

[0037] The medical staff presses their thumb against the lower end of the first isolation layer 12, while their other fingers rest naturally on the upper end of the second isolation paper 20, causing one side of the patch to fold upwards. The third isolation paper 21 is then peeled off through the exposed portion 22, and the patch body 9 is pressed to adhere the exposed second adhesive layer 10 to the skin. The second isolation paper 20 is then peeled off, exposing one end of the third isolation layer 16. The third isolation layer 16 is folded outwards until it is nearly parallel to the skin. While gently pressing the patch body 9 to maintain its position, the third isolation layer 16 is pulled outwards. The other hand smooths the patch body 9, which has detached from the outer protective isolation component 11, as the third isolation layer 16 is gradually peeled off, until the outer protective isolation component 11 is completely detached from the patch body 9. The process is repeated on the other side to achieve effective aseptic fixation of the patch to the skin.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
