Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of indwelling needle, in particular to an indwelling needle protection device and a use method thereof. BACKGROUND

[0002] The indwelling needle is also called intravenous cannula needle, and the core components include a soft catheter which can be left in the blood vessel and a stainless steel puncture guide needle core. The use of the indwelling needle can reduce the pain and fear of repeated intravenous puncture of the sick children, alleviate the anxious mood of the parents, facilitate clinical medication, rescue medication for critical patients, reduce the workload of the nurses, and reduce the pain of the sick children. Therefore, the intravenous indwelling needle is widely used in the clinic. In the face of the special group of sick children, the length of the indwelling time of the intravenous indwelling needle and the comfort of the sick children become the most concerned problems of the nurses and the parents, and are also the symbol of successful use and the prerequisite for popularization of the indwelling needle. In order to prevent the sick children from accidentally touching the indwelling needle and causing danger, some protection devices are used. The Chinese application CN201610074182.6 proposes a limb intravenous indwelling needle protection device which can more conveniently, quickly and firmly and reliably protect the intravenous indwelling needle, so that the intravenous indwelling needle will not easily fall off and shift in the body of the sick children even in the active state of the patient. However, the following problems still exist during use.

[0003] 1. The connecting end and the needle end of the indwelling needle are protected at one place. During use, the protection device needs to be temporarily removed, or the needle end is also exposed to the outside, which reduces the protection effect of the indwelling needle.

[0004] 2. During use, the automatic heat preservation cannot be realized according to different situations.
