IV automatic changing device

Abstract

The automatic intravenous injection replacement device of the present invention can adapt to the intravenous injection operation that needs to add medicinal powder into the medicinal liquid, and the whole process is automatically completed, which is convenient and quick, and uses the screw drive mechanism as the driving source of the needle tube puncture action, which can precisely control the puncture stroke, and the screw drive mechanism can provide more stable and greater puncturing force. At the same time, electromagnets and iron blocks are used as clutch means, and the rotation of the motor is converted into the puncturing action of the needle tube through the driving mode of the pendulum. The conversion of the action is completed while reducing the vertical size. The structure is ingenious, and the whole device can be flexibly set according to the infusion object, improving the versatility of the device.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic replacement device for intravenous injection. Background technique [0002] Intravenous injection is divided into transient and continuous. Transient intravenous injection is mostly directly injected into the vein with a syringe, that is, a general "injection", while continuous intravenous injection is implemented by intravenous drip, commonly known as "spot", "spot drip". "It is widely used in hospitals and clinics. Therefore, there are many studies and improvements on it. At present, the focus of improvement on continuous intravenous injection is how to replace the drug solution after the infusion is completed. For example, Patent Document 1 discloses a mechanical device for patient-controlled replacement of medical fluid. By setting multiple infusion tubes on the infusion tube fixed plate with a ratchet structure, and then manually driving the ratchet ...

AI Technical Summary

Problems solved by technology

[0006] In summary, in the prior art, there is no one that can be automatically operated, can add powder to the liquid medicine, can inject multiple liquid medicines at the same time according to the patient's own wishes, and can choose the injection sequence of different liquid medicines. , and at the same time separate the drug liquid circulation pipeline from the linkage machinery and set up an automatic intravenous injection replacement device for easy disassembly and replacement operations
