Problems solved by technology

[0004] In the prior art, there is a rubber stopper for needle tube puncture in the catheter base. The material of the rubber stopper is relatively hard. When the needle tube is inserted and pulled out, the friction force between the tube body and the rubber stopper is relatively large. It is difficult to insert and pull out, and it will cause micro tremors when inserting and pulling out. , causing discomfort to the patient

Embodiment 1

[0053] The passages of embodiments one to three are not limited to the passages extending from the outer wall of the isolation plug to the interior of the isolation plug, and passages through the isolation plug can also be used, such as Figure 15 and Figure 16 As shown, it is the channel deformation diagram of the third embodiment, the channel is a channel through the isolation plug, the drawings of the first embodiment and the second embodiment can also be changed, and the channel extending from the outer wall of the isolation plug to the inside of the isolation plug is modified to use a through The channel of the isolation plug will not be described in detail here, and the accompanying drawings of the conversion channel will also be omitted.

[0054] In order to optimize this solution, there is a lubricant in the channel of the isolation plug, which facilitates the withdrawal of the needle tube, and the resistance of the needle withdrawal is small, which will not cause dis...

Abstract

The invention discloses an isolation plug and an intravenous indwelling needle with the isolation plug. The isolation plug is an elastic body that is punctured or pulled out by a needle tube. The puncture channel covers the outer circumference of the needle tube and has a pressing force against the tube wall of the needle tube, and there is a gap between the puncture channel and the tube wall of the needle tube. The beneficial effect of the present invention is that there is a gap between the puncture channel and the tube wall of the needle tube, and the gap reduces the contact area between the tube wall of the needle tube and the puncture channel, thereby reducing the friction between the needle tube and the wall of the isolation plug; the isolation plug The channel has a deformation space, which reduces the pressure holding force of the isolation plug wall on the needle tube, thereby further reducing the friction force; there is lubricant in the channel, and the needle tube is inserted and pulled out more smoothly; the elastomer isolation plug is used, which has a strong recovery function, After the needle tube is withdrawn, the puncture hole will disappear immediately, effectively preventing blood backflow and liquid medicine leakage.

Description

technical field [0001] The invention relates to an isolation plug and an intravenous indwelling needle with the isolation plug, belonging to the technical field of medical devices. Background technique [0002] The use of intravenous indwelling needles can reduce the pain caused by repeated venipuncture of patients and the fear of injections, and reduce the anxiety of family members. [0003] The intravenous indwelling needle is generally composed of a catheter combined with a needle tube set. The catheter set is composed of a catheter base and an infusion tube connector arranged on the catheter base. The needle set is composed of a needle base and a needle tube. The needle tube is inserted into the catheter base. [0004] In the prior art, there is a rubber stopper for needle tube puncture in the catheter base. The material of the rubber stopper is relatively hard. When the needle tube is inserted and pulled out, the friction force between the tube body and the rubber stopp...
