Description

Technical Field

[0001] The utility model belongs to the technical field of medical supplies, and particularly relates to a decompression patch for an indwelling needle. Background Art

[0002] Indwelling needles, also known as cannula needles, have core components including stainless steel needle cores, soft outer sleeves and plastic needle holders. As an important medical tool, they play an indispensable role in clinical medicine. This needle is mainly used for intravenous infusion therapy and can be left in the patient's blood vessels for a long time. Its core purpose is to reduce the pain caused by repeated intravenous punctures, reduce the fear and anxiety of injections, and thus facilitate clinical medication, especially in the rescue process of acute and critically ill patients, to quickly and effectively deliver drugs. In addition, the use of indwelling needles can greatly reduce the workload of medical staff and improve work efficiency. In the routine use of indwelling needles, medical staff will first properly disinfect the patient's skin to ensure that the puncture site is clean and sterile. Then, select an appropriate vein for puncture and insert the indwelling needle into the blood vessel; after the puncture is successful, the outer sleeve of the indwelling needle is sent into the blood vessel, and the stainless steel needle core inside the indwelling needle is withdrawn; finally, the infusion set is connected to the heparin cap for subsequent infusion therapy. During the entire process, in order to ensure the stability and safety of the indwelling needle, medical staff usually adopt some fixation measures, such as using adhesive tape.

[0003] Although the use of indwelling needles brings many conveniences, the indwelling needles set up in the conventional use mode will have the problem of compressing the skin. This is because the outer sleeve and plastic needle holder of the indwelling needle will continuously compress the skin, which may cause poor local blood circulation in the skin. This compression may not only cause skin redness, swelling and pain, but may even cause skin necrosis and venous thrombosis in severe cases. Especially in summer, the patient's skin is prone to sweating, and the frequent activities make the compression problem more prominent. In addition, children are more susceptible to compression due to their delicate skin and loose subcutaneous tissue, resulting in a higher incidence of pressure sores than adults. These problems not only increase the pain of patients, but may also cause medical disputes.

[0004] After searching, the Chinese utility model application document with the existing announcement number CN208552716U discloses an indwelling needle for preventing the formation of pressure sores, "including a soft needle, a needle seat, a needle wing, a connecting tube and an extension tube, one end of the needle seat is conductively connected to the soft needle, and the other end is connected to the needle wing, the needle wing is provided with a steel needle, the steel needle is fixedly connected to the needle wing and passes through the soft needle, the extension tube is conductively connected to the needle seat through the connecting tube, and also includes a protective sleeve, an anti-pressure sore pad and a fixing belt, the protective sleeve is arranged on the needle seat, the anti-pressure sore pad and the fixing belt are respectively fixedly connected to the outer wall of the protective sleeve and are located on opposite sides of the protective sleeve, the anti-pressure sore pad has the functions of decompression, sweat absorption and breathability, and the fixing belt is fixed by Velcro", although the indwelling needle for preventing the formation of pressure sores in the utility model can play a role in preventing the formation of pressure sores by providing an anti-pressure sore pad, but the stability of the indwelling needle is insufficient, and it cannot completely prevent the pressure of the needle seat on the skin, and has certain limitations.

[0005] Therefore, we urgently need a device that can effectively solve the problem of conventional indwelling needles compressing the skin, to improve patient comfort and satisfaction, and to reduce the risk of medical disputes. Utility Model Content
