Description

Technical Field

[0001] The utility model relates to an infusion port technology, in particular to an infusion port butterfly needle removal device for preventing needle sticks. Background Art

[0002] An infusion port is a vascular access device that is completely implanted in the patient's body. It can provide a safe and reliable venous access for patients who require long-term and repeated infusion treatment, reducing the pain and risk of repeated venipunctures. Because its function is similar to the port we often mention, it is a "port" for intravenous treatment, so it is called an infusion port. Through it, not only can various drugs and fluids be infused and parenteral nutrition support therapy be performed, but also blood products can be infused or blood samples can be collected. The intravenous infusion port can be divided into two major parts: a completely implanted part and an external use part. The implanted part consists of an injection seat and a port seat, and the external use part is mainly a butterfly wing needle.

[0003] When the infusion using the infusion port is completed, the medical staff needs to use their left hand to press the infusion port seat under the patient's skin and use their right hand to pull out the butterfly wing needle. However, due to the tight texture of the silicone puncture diaphragm on the top of the infusion port base, the medical staff needs to use force to remove the butterfly wing needle. During the process of pulling out the butterfly wing needle tip, due to the angle problem, the three fingers of the medical staff's left hand are very close to the needle tip of the butterfly wing needle. The needle tip of the butterfly wing needle can easily pierce the medical staff's gloves and scratch his left hand, putting the medical staff at risk of contracting infectious diseases. Utility Model Content

[0004] The purpose of the utility model is to provide a device for removing a butterfly-wing needle from an infusion port to prevent needle stick injuries, so as to solve the above-mentioned deficiencies in the prior art.

[0009] Furthermore, the handle is a bent plate, and one side of the bent plate is fixedly connected to the port seat stabilizer.

[0010] Compared with the prior art, the present invention provides an anti-needlestick infusion port butterfly needle removal device. The handle and port seat stabilizer are provided to press and fix the port seat of the infusion port when the butterfly needle is removed, thereby assisting medical personnel in removing the butterfly needle. This prevents the three fingers of the medical personnel's left hand from being very close to the needle tip of the butterfly needle due to angle problems during the process of removing the butterfly needle, which may cause the needle tip of the butterfly needle to easily pierce the medical personnel's gloves and scratch their left hand.

[0011] By pulling the latch, the latch squeezes the spring and moves the latch out of the socket. At this time, the fixed part and the rotating part can rotate relative to each other, so that the shape of the handle can be adjusted to adapt to the different postures and positions of different patients when assisting in removing the butterfly wing needle on the infusion port seat. It can be adjusted so that medical staff can hold the port seat stabilizer at different angles to press the infusion port seat, which is more practical and reduces the risk of medical staff being stabbed and infected with diseases.
