Description

An infusion port fixer

technical field

The utility model relates to the field of medical equipment, in particular to a fixer for an infusion port.

Background technique

The infusion port is specially designed for patients who need long-term and repeated infusions. It is suitable for intravenous injection or continuous infusion of chemotherapy drugs, parenteral nutrition (TPN), and can also be used for antibiotics, blood products, ordinary intravenous fluids and blood collection. intravenous therapy. The infusion port is mainly composed of an injection seat for puncture and an intravenous catheter. The end of the catheter is located in the central vein. It is an intravenous infusion device that can be implanted subcutaneously and left in the body for a long time.

The infusion port, because it is implanted under the skin and made of silicone material, is light in weight and only the size of a button on ordinary clothes. It is not obvious from the outside that the patient is equipped with the infusion device. The patient is comfortable and does not affect the appearance or affect the patient. Daily life such as bathing, swimming, etc.

The infusion product compatible with Bard's implanted infusion port is a butterfly wing needle. The butterfly-wing needle is different from the traditional puncture needle. The front end of the butterfly-wing needle is a non-linear needle with a barb. Hold the butterfly needle in the other hand. However, during the operation, it is difficult to grasp the direction of pulling out and puncturing the butterfly-wing needle, and the barb-shaped needle of the butterfly-wing needle often stabs the hands of medical staff.

The Chinese patent document with application number 201420176799.5 describes a needle puller for infusion ports, which includes a handle, a connecting part and a base, and the two ends of the connecting part are respectively connected to one end of the handle and the base, and the handle The plane where it is located is parallel and spaced above the plane where the upper side of the base is located; in addition, a V-shaped opening is formed at the other end of the base. In this solution, the infusion port is fixed by snapping the V-shaped opening into the infusion port and then pressing the base, which can prevent the medical staff from stabbing their hands when the butterfly wing needle is pulled out. However, there are many defects in this scheme, specifically:

(1) After the infusion port is implanted subcutaneously, both the injection seat and the venous catheter are located under the skin. When the device pulls out the needle, it is necessary to press the base firmly to push down the injection seat. During the pressing process, it is easy to cause the injection seat to be separated from the intravenous catheter, causing accidents;

(2) The needle base is made of plastic material, and the moment the needle base contacts the skin, it will cause spasm to a certain extent, making it difficult to pull out the needle;

(3) The existing infusion port injection seat is an arc-shaped structure without sharp corners, and its purpose is to prevent the patient's skin from being punctured. However, the device is inserted into the injection seat of the infusion port through the V-shaped bayonet. The infusion seat is only stressed in the vertical direction and has no friction in the horizontal direction. Correspondingly, the injection seat of the infusion port is easy to slip during the needle withdrawal process.

Therefore, how to design a brand-new infusion port fixation device to solve the problem that the hand of the medical staff is easily stabbed by the butterfly wing needle in the process of pulling out the needle and puncturing is what those skilled in the art need to solve.

Utility model content

The purpose of this utility model is to overcome above-mentioned deficiencies in the prior art, provide a kind of simple in structure, use convenient transfusion port fixer. The fixer provided by the utility model can clamp the infusion port in the horizontal direction, thereby preventing the injection seat from being separated from the venous catheter, and solving the problem that Chinese medical staff are easily injured by needles in the prior art.

And the inner sides of the first clamping part and the second clamping part are provided with non-slip silicone pads.

Preferably, the bottom surface of the first clamping part is fixedly connected to the first anti-spasmodic silicone pad, and the cross-section of the first anti-spasmodic silicone pad is the same as the cross-sectional structure of the first clamping part.

Preferably, the bottom surface of the second clamping part is fixedly connected to the second anti-spasmodic silicone pad, and the cross-section of the second anti-spasmodic silicone pad is the same as the cross-sectional structure of the second clamping part.

Preferably, the inner ring of the first bracelet is provided with anti-skid lines.

Preferably, the inner ring of the second bracelet is also provided with anti-skid lines.

The beneficial effects of the utility model are:

(1) The overall shape of the device is clamp-shaped, so that medical staff do not need to directly fix the infusion port with their hands, so as to avoid the hand being stabbed by the butterfly wing needle;

(2) Apply horizontal force to the infusion port during use, and the non-slip silicone pad prevents the infusion port from sliding, realizing the fixation of the infusion port; the horizontal force is low during the fixation process, which can prevent the injection seat from detaching from the venous catheter;
