Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the present invention, taken in conjunction with the accompanying drawings and the detailed description, is given in a non-limiting manner.

As shown in fig. 1 to 3, the indwelling needle of the present embodiment comprises an indwelling needle body 1, a connector 2 and a drug adding tube 3, wherein the indwelling needle body 1 is communicated with a connecting tube 4, and the connecting tube 4 is communicated with the drug adding tube 3 through the connector 2; the joint 2 is a connecting sleeve with openings at two ends, the connecting pipe 4 is inserted into one end of the joint 2 and is in threaded connection with the joint, and the dosing pipe 3 is inserted into the other end of the joint 2 and is in threaded connection with the joint. The indwelling needle further includes a cap 41 for sealing the port of the connecting tube 4, and the cap 41 is fitted over the connecting tube 4 and threadedly coupled thereto. The connecting pipe 4 is provided with an elastic belt 5, and the end of the elastic belt 5 is fixedly connected with the sealing cover 41. When the medicine is not needed to be added, the sealing cover 41 can seal the port of the connecting pipe 4 and prevent the liquid from leaking out of the end of the connecting pipe 4. The elastic band 5 prevents the cover 41 from being lost.

Two thread areas with opposite thread directions are formed on the inner wall of the joint 2, and the connecting end of the connecting pipe 4 and the connecting end of the dosing pipe 3 are respectively positioned in the two thread areas of the joint 2. The end of the dosing tube 3 is provided with an inserting tube 31, the inserting tube 31 is communicated with the dosing tube 3, and after the joint 2 is rotated, the inserting tube 31 is inserted into the connecting tube 4.
