Problems solved by technology

When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. It is widely used in infusion therapy. After some indwelling needles are used, their needle cores are either directly exposed to the air, or are only placed in ordinary tubes, which is dangerous. In addition, after the existing indwelling needles are opened, if they are not used in time, Catheter is at risk of snapping

Description

technical field [0001] The invention relates to a medical device, in particular to an indwelling needle. Background technique [0002] An indwelling needle consists of a flexible catheter and stylet that can be placed in a blood vessel. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter has completely entered the blood vessel, the needle core is withdrawn, and only the soft catheter is left in the blood vessel for infusion therapy. It is widely used in infusion therapy. After some indwelling needles are used, their needle cores are either directly exposed to the air, or they are only placed in ordinary tubes, which is dangerous. In addition, after the existing indwelling needles are unpacked, if they are not used in time, There is a risk of the catheter breaking off. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating in order to create a new type of indwelling needl...
