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out more smoothly; the elastomer isolation plug is used, which has a strong recovery function, After the needle tube is withdrawn, the puncture hole will disappear immediately, effectively preventing blood backflow and liquid medicine leakage.

The invention discloses a connector and a connector assembly. The connector comprises a plurality of guide blocks and at least one connecting port, wherein each of the plurality of guide blocks has a first surface and a second surface opposite to each other, and a third surface adjacent to the first surface and the second surface; a first guide groove is concavely formed in the first surface, a second guide groove is concavely formed in the second surface, a clamping hole is formed between the first guide groove and the second guide groove in a penetrating mode, and a locking hole is formed in the third surface; each of the at least one connecting port is arranged on two adjacent guide blocks in the plurality of guide blocks, one side of each of the at least one connecting port faces the first surface of one of the two guide blocks, and the other side of each of the at least one connecting port faces the second surface of the other guide block. According to the connector, the first guide groove and the second guide groove in the guide block can assist in guiding the transmission end, so the plugging and unplugging process is smooth.
