Problems solved by technology

[0002] The current indwelling needles are all set in one cavity. When two drugs need to be injected at the same time, they can only be injected or infused in the same infusion port and the same infusion cavity. Different drugs are injected in the same channel, and antagonistic reactions between drugs are prone to occur, affecting drug efficacy

Embodiment Construction

[0009] Below in conjunction with Fig. 1, describe in detail the concrete work situation that the present invention proposes, figure 1 The main body 7 of the indwelling needle is fixed with a silicone tube 1, an infusion steel needle 2, and a main infusion connector 5. A silicone membrane 3 is installed in the silicone tube 1 to divide the silicone tube 1 into a main infusion chamber 4 and an auxiliary infusion chamber 8. 8 A one-way valve 9 is installed at the front end, and an auxiliary infusion connector 6 is installed on the indwelling needle main body 7, and the one-way valve 9 is connected with the auxiliary infusion connector 6.

[0010] Silicone tube 1 is divided into main infusion chamber 4 and auxiliary infusion chamber 8 by installing silicone membrane 3 in the silicone tube 1, and a one-way valve 9 is installed at the front end of the auxiliary infusion chamber 8. When another drug needs to be infused, the drug is connected On the auxiliary infusion joint 6, the one...

Abstract

The invention relates to an indwelling needle. A silicon membrane is installed inside a silicone tube and divides the silicone tube into a main infusion cavity and an auxiliary infusion cavity, and a one-way valve is installed at the front end of the auxiliary infusion cavity. When the other drug needs to be infused, the drug is connected to an auxiliary infusion connector, the one-way valve is opened, the drug flows into the blood vessel through the auxiliary infusion cavity, infusion of a drug in the main infusion cavity is not affected, and the two drugs will not react with each other when encountering each other in an indwelling needle body. When infusion is not conducted, the one-way valve is closed, blood will not flow back to the auxiliary infusion cavity, and therefore the purpose that different drugs are infused into multiple cavities is achieved.

Description

technical field [0001] The invention is an indwelling needle in the field of medical technology, which is especially suitable for injection of critically ill patients. Background technique [0002] The current indwelling needles are all set in one cavity. When two drugs need to be injected at the same time, they can only be injected or infused in the same infusion port and the same infusion cavity. Different drugs are injected in the same channel, and antagonistic reactions between drugs are prone to occur, affecting The efficacy of the drug. Contents of the invention [0003] The purpose of the present invention is to provide an indwelling needle to achieve the purpose of multi-cavity input of different medicines. [0004] Its purpose is achieved in this way, an indwelling needle is composed of a silicone tube, an infusion steel needle, a silicone membrane, a main infusion chamber, a main infusion connector, an auxiliary infusion connector, the main body of the indwellin...
