Description

An implantable transfusion port puncture positioning patch

technical field

The utility model relates to the technical field of medical appliances, in particular to an implanted transfusion port puncture positioning sticker.

Background technique

Implantable Venous Access Port (PORT) is an intravenous infusion device that is implanted subcutaneously and left in the body for a long time. It can be used for infusion of drugs, fluid replacement, nutritional support, blood transfusion and other treatments, and can also be used for blood collection. The infusion channel can be monitored by puncturing the infusion port with an atraumatic probe, reducing the pain and difficulty of repeated venipuncture. The puncture septum can be punctured 1,000 times with a 19G non-invasive puncture needle. The butterfly-wing needle can be used continuously for 7 days. The infusion port can be used for 19 years, and the maintenance is simple. It is not easy to be infected in the body for a long time. It can be maintained once every 4 weeks during the treatment interval . This technology has many years of application experience at home and abroad, and it is widely used in domestic cancer chemotherapy patients. However, in the long-term clinical application, the use of the infusion port has also exposed some shortcomings: three fingers are required to fix the injection seat during the puncture process, but for obese patients or patients with a lot of local sweating, it is difficult or even impossible to fix the injection seat. When the needle is inserted vertically, there are situations such as poor blood return and infusion of the drug solution; due to the difficulty in fixing the injection seat, and at the same time, the operator often chooses the center as the puncture point in order to ensure vertical needle insertion, resulting in repeated punctures at the same part of the punctured septum and damage to the puncture The diaphragm greatly shortens the service life of the infusion port. For example, infusion of chemotherapy drugs may even cause extravasation of chemotherapy drugs. The consequences are unimaginable.

Utility model content

The purpose of this utility model is to solve the above-mentioned deficiencies in the background technology, and to provide an implantable infusion port puncture positioning sticker, which can provide a non-damaging needle puncture success rate on the one hand, and on the other hand, prevent the infusion port from puncturing the same part of the diaphragm Repeated puncture ensures the service life of the infusion port and improves patient satisfaction.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

An implantable infusion port puncture positioning sticker, used to determine the position of the top surface of the infusion port injection seat, the positioning sticker includes a mark area on the edge and a hole-shaped puncture hole area on the inner side, the positioning sticker is provided with n (n≥1) strips pass through the bar in the center of the positioning sticker, and the bar divides the identification area and the puncture hole area into 2n parts.
