Description

An infusion port tail needle extractor

technical field

The embodiments of the utility model relate to the technical field of medical devices, in particular to an infusion port tail needle extractor.

Background technique

Implantable venous infusion port is a novel infusion method for long-term infusion. Due to the long course of disease and many treatment options, cancer patients need to undergo repeated chemotherapy, surgery, anti-infection and nutritional support. The traditional infusion method is to inject fluid through peripheral superficial venous puncture, which is likely to cause superficial phlebitis, drug leakage, local Complications such as hard swelling and even large-scale tissue necrosis have caused great pain to patients. The infusion port is placed into the human body in order to reduce the stimulation of chemotherapy drugs to the patient's blood vessels, and generally mainly includes an injection seat, a catheter and a butterfly wing needle. After the injection seat is implanted subcutaneously, the catheter inserted into the central vein is connected to establish a long-term vascular channel, which can play a similar role as a port, so it is called "infusion port".

Since the injection seat of the infusion port is a rubber pad, it has the ability to be elastic and easy to puncture repeatedly. Therefore, in the process of pulling out the butterfly wing needle, the medical staff needs to temporarily fix the butterfly wing needle with hands or cotton swabs or use auxiliary devices. In order to pull out the butterfly wing needle, such as the auxiliary device adopted in the prior art, a kind of auxiliary device for pulling out the needle in the infusion port disclosed by the publication number CN206577199U comprises a slotted flaky infusion port seat fixing piece and a handle , the width of the slot is larger than the diameter of the needle of the needle and smaller than the upper surface area of the base of the infusion port, in this way, the nurse and the patient are protected from needle stick injuries. However, in this type of technical solution, since there is no protective structure on the needle tip, there is still the possibility of being stabbed by the needle tip, and there is also the defect that it is difficult to take the needle with the butterfly wing needle due to repeated puncturing.
