Description

A compound non-invasive needle puncture fixer for venous infusion port

technical field

The utility model belongs to clinical medical consumables, in particular to a compound non-damaging needle puncture fixer for an intravenous infusion port.

Background technique

The intravenous infusion port is currently the preferred implantable subcutaneous long-term infusion device in the world. It is mainly used for patients who need long-term and repeated infusion. It is suitable for intravenous injection or continuous infusion of chemotherapy drugs, parenteral nutrition (TPN) , It can also be used for almost all intravenous treatments such as antibiotics, blood products, ordinary intravenous rehydration and blood collection. The intravenous infusion port can reduce the pain caused by chemotherapy and central catheter-related complications for patients, and the simple maintenance can bring comfort and convenience to patients. After the catheter is placed, it needs to be punctured with a non-damaging needle before each infusion, and if the non-damaging needle cannot be effectively fixed during the infusion after puncture, it will cause the phenomenon of needle body falling off, drug extravasation, skin abrasion, infection, etc., and clinical Gauze is often used in conjunction with adhesive tape or application for fixation during work. The operation is cumbersome and requires high technical skills for nurses. Improper operation may also lead to the phenomenon that the non-damaged needle is not firmly fixed or the needle body falls off, which increases the medical risk of patients.

Therefore, research on a new compound fixer for non-invasive needle puncture of implanted venous infusion port has always been a focus of attention of those skilled in the art.

Contents of the invention

The purpose of the utility model is to provide a composite venous infusion port non-injury needle puncture fixer.

In order to achieve the above tasks, the utility model takes the following technical solutions:

A compound non-injury needle puncture fixer for venous infusion ports, including a film in contact with the human body, is characterized in that a gasket is fixed on the film, and the gasket has pinholes and grooves communicating with the pinholes.

Another feature of the utility model is that there are multiple air holes on the gasket.

The material of the gasket is sponge, felt or soft plastic.

The composite venous infusion port non-injury needle puncture fixer of the utility model has the following advantages:

1. It can effectively fix the non-damaged needle to avoid the needle falling off and the drug extravasation;

2. Protect the skin at the puncture site to avoid friction between the needle body and the skin causing abrasions and infections;

3. The structure is simple, the production cost is low, and the operation is convenient.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Detailed ways

Referring to Fig. 1, the present embodiment provides a specific structure of a non-invasive needle puncture fixer for a composite venous infusion port, including a film 3 in contact with the human body, a gasket 2 is fixed on the film 3, and a spacer 2 is provided on the film 3. There are pinholes 1 and channels 4 communicating with the pinholes 1 .

The material of the gasket 2 can be selected from sponge, felt or soft plastic, and there are a plurality of air holes 5 on the gasket 2 .

The composite venous infusion port non-invasive needle puncture fixer prepared in the above embodiment, the specific application process is shown in Figure 2. After the venous infusion port 8 is implanted in the skin 10, it is connected to the venous blood vessel 11 through the catheter 9. When using this embodiment When the non-invasive needle puncture fixer 7 of the composite venous infusion port is used, after the puncture of the non-invasive puncture needle 6, the needle head of the non-invasive puncture needle 6 is placed into the needle hole 1 through the channel 4, and the gasket 2 is placed under the needle head and To play a fixing role, the film 3 fixes the non-invasive needle puncture fixer 7 of the compound venous infusion port of this embodiment on the surface of the skin 10 to complete the operation.
