Description

Technical Field

[0001] The utility model relates to the field of clinical puncture, in particular to a needleless infusion connector auxiliary device and a needleless infusion tool set. Background Art

[0002] In clinical intravenous infusion, indwelling needles have been widely used. Since they can effectively avoid repeated punctures, they can relieve the pain suffered by children due to repeated venous punctures, reduce the irritation to venous blood vessels to a certain extent, and also reduce the work intensity of nursing staff and improve work efficiency to a certain extent. A needleless infusion connector is a mechanism used to connect an indwelling needle to prevent blood reflux and infuse liquid medicine.

[0003] During use, after the indwelling needle is successfully punctured, it is connected to the needleless infusion connector, and then fixed to the skin with a transparent dressing. The needleless infusion connector directly contacts the skin surface. To prevent skin pressure injury, a cotton ball is often placed between the connector and the skin clinically to prevent pressure injury. However, there are several problems with this operation: ① The complete sterile cotton ball is too large, and it needs to be manually torn by the nursing staff during use, so the shape of the torn cotton ball is not fixed. 1) When the cotton ball is too small, it cannot prevent pressure injury. 2) When the cotton ball is too large, it affects the fixation effect of the indwelling needle. 3) When the cotton ball is too high, it affects the angle of the indwelling needle and causes poor infusion. 4) The cotton wool of the cotton ball is loose, and it is easy to adhere to the indwelling needle when tearing the cotton ball. 5) The cotton ball may shift, and pressure injury may still occur. ② The actions of tearing and padding the cotton ball are between the two actions of puncturing the indwelling needle and fixing the dressing with the adhesive, increasing the risk of catheter slippage. In addition, since the needleless infusion connector itself has no adhesiveness but has a certain weight, the indwelling needle has a risk of falling off.

[0004] In summary, there is an urgent need for a device that can effectively reduce the pressure injury caused by the needleless infusion connector. Content of the Utility Model
