Description

A device for preventing needle stick injuries in infusion port

technical field

The utility model relates to the technical field of auxiliary devices for infusion ports, in particular to a device for preventing needle stick injuries in infusion ports.

Background technique

Implantable infusion port, also known as implantable central venous catheter system, referred to as infusion port, is an implantable and long-term indwelling central venous infusion device embedded in subcutaneous tissue. The intravenous infusion port was originally invented by Broviac and others. It is mainly used in the clinic to solve the problem of difficult peripheral infusion in tumor patients. Because it is located under the skin, it has a low chance of infection and does not affect the normal life of patients. It is gradually recognized by many clinical oncologists.

At present, the traditional infusion port puncture method is adopted in clinical practice. Due to the different operation techniques and proficiency of nurses, the success rate of puncture cannot be guaranteed, which increases the patient's physical pain and physical and mental burden. The patient sweats and shakes due to tension. Nurses may cause needle stick injuries during this time, which poses a serious threat to the physical and mental health of nurses. To this end, we propose a device for preventing needle stick injuries in the infusion port.

The symmetrical side of the needle-pulling hook is fixed with an operation panel surface, the surface of the operation panel is provided with a butterfly-wing needle needle hole, and a butterfly-wing needle guide groove is opened on the side of the butterfly-wing needle needle hole away from the handle.

Preferably, the needle-pulling hook, the handle and the operating panel are all made of stainless steel.

Preferably, the needle-pulling handle, the handle and the operating panel are integrally formed by casting.

Preferably, the inner surface of the butterfly-wing needle placement needle hole and the butterfly-wing needle guiding groove are arc-shaped.

Preferably, the corners of the needle-pulling hook, the handle and the surface of the operation panel are all provided with chamfers.

Preferably, the cross section of the handle is arc-shaped.

Compared with the prior art, the beneficial effect of the utility model is: during the liquid injection operation, confirm the edge of the injection seat, hold the hand-held handle, and place the bottom end of the hand-held handle of the device and the local skin outside the infusion port seat reasonably, Then press the handle position by hand to press the device stably, the non-damaged needle is inserted vertically into the needle hole of the butterfly-wing needle, until the non-damaged needle is inserted into the bottom of the reservoir, and then the butterfly-wing needle is removed through the butterfly-wing needle guide groove Needle inserter, this device for preventing needle puncture in the infusion port improves the success rate of infusion port puncture, protects blood vessels, reduces the incidence of drug extravasation, improves the comfort of the patient during puncture, and reduces the risk of infection. It reduces the incidence of needle stick injuries for nurses, relieves the psychological pressure during catheter placement, enables nurses to puncture faster and more effectively, locates accurately, facilitates the operation of nurses, and improves work efficiency.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-3, the present utility model provides a technical solution: a device for preventing needle stick injuries in an infusion port, comprising a needle-pulling hand-held hook 1, a hand-held handle 2, an operation panel 3, a butterfly wing needle needle hole 4, a butterfly wing needle The wing needle guide groove 5 and the corrugated groove 6, the bottom side of the handle 2 is fixed with a needle-pulling hand-held hook 1, which is convenient for hand-held pressing of the needle-pulling hand-held hook 1 to press the device stably, and the needle-pulling hand-held hook 1 is far away from the hand-held handle 2. The needle-pulling hand-held hook 1 has a corrugated groove 6 on the surface, which is convenient for fingers to stably apply force to press the device. The top of the hand-held handle 2 is located on the symmetrical side of the needle-pulling hand-held hook 1, and an operation panel surface 3 is fixed on the surface of the operation panel surface 3. A butterfly-wing needle setting pinhole 4 is opened, and a butterfly-wing needle guiding groove 5 is formed on the side of the butterfly-wing needle setting needle hole 4 away from the hand-held handle 2 .

During the injection operation, confirm the edge of the injection seat, hold the handle 2 and place the bottom end of the handle 2 of the device and the local skin outside the infusion port seat, and then press the handle 2 position to press the device stably. The injured needle is vertically inserted into the needle hole 4 of the butterfly wing needle, and when the non-injured needle is inserted into the bottom of the liquid storage tank, the butterfly wing needle needle device is removed through the butterfly wing needle guide groove 5.
