Abstract

The invention discloses an automatic replacement device for intravenous injection. The device can adapt to an intravenous injection operation needing to add medicine powder into liquid medicine, the whole process is automatically completed, and convenience and quickness are achieved. A lead screw transmission mechanism is used as a driving source of the needle tube puncture action, and the puncture stroke can be accurately controlled. The lead screw transmission mechanism can provide more stable and larger puncture force. Meanwhile, an electromagnet and an iron block are used as clutch means,rotation of a motor is converted into puncture action of a needle tube through a swing rod driving mode, conversion of the action can be completed while the vertical size is reduced, the structure isingenious, the whole device can be flexibly and correspondingly arranged according to an infusion object, and the universality of the device is improved.

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 ...
