Preferably, the outer wall of the indwelling needle sleeve is provided with an indwelling needle sheath, so that the indwelling needle sleeve can be protected from bacterial infection.
Preferably, the outer wall of the retaining needle sleeve seat is fixedly provided with a hose connector, and the hose is matched with the hose connector, so that the hose can be conveniently detached and replaced when the hose is damaged.
Preferably, the outer wall of the hose is fixedly provided with a flow stopping clamp with a specification adapted to the outer wall, so that the circulation condition of the hose can be controlled.
Preferably, the outer wall of the infusion tee joint is fixedly provided with a heparin cap which is communicated with the infusion tee joint, so that the use time of the indwelling needle can be prolonged, and infection and local blood coagulation can be prevented.
Preferably, the hose connector, the conical connector and the indwelling needle sleeve seat are provided with protective caps with specifications matched with each other, so that the joints can be sealed and protected, and bacterial infection is reduced.
1. According to the three-way indwelling needle, after the puncture needle and the indwelling needle sleeve are inserted into a blood vessel through the puncture needle, the needle cap and the hemostat, the puncture needle is pulled out through the needle cap, the needle head is prevented from being left in the blood vessel to damage the blood vessel of a patient, the hemostat can prevent blood from flowing out of the right side of the indwelling needle sleeve seat, the indwelling needle and the indwelling needle sleeve seat are also convenient to fix, and the safety is high;
2. Simultaneously through the setting of conical joint, malleation connect, drainage hose and collecting pipe, dock the input and the conical joint that connect the malleation, then be connected drainage hose and collecting pipe, open the flow stopping clamp, blood flows into the collecting pipe in through malleation joint is automatic, accomplishes the collection of blood, and malleation connects can prevent the backward flow of blood, connects the conical joint with infusion after the blood sampling is accomplished and connects, can infuse, and the practicality is high.
