Description

Combined Indwelling Needle/Indwelling Tube Holder

technical field

The invention belongs to the technical field of medical supplies, and in particular relates to a fixer for fixing an indwelling needle/indwelling tube.

Background technique

Indwelling catheters, also known as trocars, have the main advantages of reducing the pain caused by repeated punctures, protecting blood vessels, facilitating clinical medication and emergency rescue, and reducing the workload of nurses. The existing fixed application of indwelling needles is mainly fixed in the way of overall coverage. Since the fixed application integrates the needle head and the needle port, the indwelling needle is often affected during the removal process, thereby pulling the needle port, causing pain , and because most of the indwelling needles are made of plastic tubes, they are very easy to bend, which affects the normal flow of the medicinal solution and must be replaced. At present, most indwelling needles have the function of anti-inflammation, but generally do not have the function of analgesia, let alone the function of using far-infrared rays to radiate the body tissues around the needle port to improve blood circulation and relieve pain.

In patent No. 201120194316.0, a kind of venous indwelling needle fixing device is disclosed. Its advantage is that it can fix the venous indwelling needle well. The disadvantage is that the fixed venous indwelling needle is stuck on the double-sided compress. Tear off the double-sided compress sticking to the skin, it is easy to pull the needle tube and cause pain.

Patent No. 200620161724.5 discloses a fixed application of an intravenous indwelling needle for head vein injection. The problem is that the indwelling needle is still fixed on the skin with an adhesive, and the needle port will still be pulled when the adhesive is torn off.

In addition, since the absorbent pad will be polluted by the overflow of the pinhole, and the efficacy of the drug will decrease after a long time of use, it is necessary to replace the indwelling needle film regularly. In fact, the protection of the pinhole is the key point. The current indwelling needle film can only be completely replaced when replacing it. It is impossible to replace only the indwelling needle film above the key protection area in a targeted manner. On the one hand, it is difficult to replace. Also caused certain waste on the other hand.
