TW425295B - A hidden type butterfly muti-functional IV administration set - Google Patents

Abstract

This invention is a hidden type butterfly muti-functional IV administration set which include a connect tube and a safety slide cover. The top of the connect tube connect with needle and the bottom of it connect with tube. There is a connect flume in the connect tube and there are ribs in the connect flume. There is a connect edge in the safety slide cover. When the safety slide cover pull up, the safety slide cover will be blocked in the connect flume following the ribs. The needle will then be hidden in the safety slide cover for preventing the hurt of operator by causing AIDS, hepatitis, blood infection disease etc.

Description

After the addition of the invention patent No. 8 6 1 0 1 9 3, it can be retracted: injection by others [Background of the invention of the invention 丨 Application No. infusion drip set is currently in Set), scalp: device are all based on | Intravenous injection I cover by injection needle i head cover and then by: the extravagant hole is very small and accidentally infected.

The structure is different: A. Announcement No. 3 2 3 9 5 8 is the needle (1 6) of the "general syringe" which uses the cone part (50) to open the cone hole (3 7) and destroy it. The spring (40) is released, and the spring (40) is used to spring the needle (16) back into the syringe (14). B. In this case, after the drip device is used, the "guide rib (1 2)" is used to make the safety sliding sleeve (4) slide into the fastening groove (11) more smoothly, and the injection needle (3) Envelop. 4. Operational safety: A · Announcement No. 32 39 58 During operation, the tapered hole (3 7) is opened and destroyed by the taper (50). It must be done with great force, but this is very large. The urging force of the spring and the spring (40) rebounding the needle (16) into the syringe (14) will inevitably cause the injection needle to vibrate strongly and hurt the patient, which is very dangerous. B. In this case, the “guide rib (12)” can be used to make the safety sliding sleeve (4) slide into the fastening groove (Π) more smoothly. The operation process is very safe. From the above comparison, it can be seen that the object of application of this case is not only different from the notice No. 326691 and the notice No. 323958, but also different in function and structure from the notice No. 326691 and the notice No. 323958. At the same time, the case is very safe in operation. However, Bulletin No. 326691 and Bulletin No. 32395 8 are very dangerous in operation.
