Description

Needleless infusion connector auxiliary device and needleless infusion tool set

Technical Field

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

In clinical intravenous transfusion, the indwelling needle is widely used, repeated puncture can be effectively avoided, so that pain of an infant patient born by repeated intravenous puncture is relieved, simultaneously, the stimulation to vein is relieved, the working intensity of nursing staff can be reduced to a certain extent, and the working efficiency is improved. The needleless infusion connector is a mechanism for connecting an intravenous indwelling needle, preventing blood from flowing back and infusing liquid medicine.

When the disposable needle is used, the disposable needle is connected with the needleless infusion connector after successful puncture, and then is stuck and fixed on the skin by using the transparent application, the needleless infusion connector directly contacts the surface of the skin, and in order to prevent skin pressure injury, a cotton ball is usually used between the connector and the skin in clinic to prevent the pressure injury, but the operation has the following problems that ① is too large in a complete sterile cotton ball, and a nursing staff is required to manually tear the disposable cotton ball when the disposable cotton ball is used, so that the torn cotton ball is not fixed in shape. 1) Cotton balls do not function to prevent compressive damage when too small. 2) The cotton ball is too large to influence the fixing effect of the indwelling needle. 3) Too high a cotton ball affects the angle of the indwelling needle, causing poor infusion. 4) The cotton ball is loose and is easy to adhere to the retaining needle when being torn. 5) The cotton ball is likely to shift and still possibly cause pressure injury. ② The actions of tearing cotton balls and filling cotton balls are between the two actions of sticking and fixing the remaining needle after puncturing, and the risk of slipping of the catheter is increased. In addition, since the needleless infusion set itself is not adhesive but has a certain weight, there is a risk that the indwelling needle falls off.

In view of the foregoing, there is a need for a device that effectively reduces the pressure damage caused by needleless infusion connectors.
