Solution filtering injection appliance for Parkinson's drugs

Abstract

The invention discloses a solution filtering injection appliance for Parkinson's drugs and belongs to the field of medical equipment. The technical scheme includes that the solution filtering injection appliance comprises an appliance body, a shell, a stock solution outer shell and an injection needle, the shell is fixed on the appliance body, a visual plug is penetratingly connected onto the shell, one end of a piston rod is fixedly connected with a piston stop rod while the other end of the same is fixedly connected with a plug, a piston plate is tightly attached to the inner wall of the visual plug, an operation element is movably connected to the top of the appliance body, and a spring is arranged at the bottom of the operation element. The spring state can be unlocked by pushing the operation element, the visual plug can be pushed to move downwards, the piston plate can extrude the solution in a volumetric flask to move downwards, the piston stop rod can limit motion of the pistonafter the injection of the solution is completed, the spring can have the piston plate reset timely, injection can be automatically completed by the injection appliance, clamping is less prone to occurrence, and good injection effect is achieved.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a filtering injection device for a dissolved solution of Parkinson's medicine. Background technique [0002] Parkinson’s drug dissolving solution filtration injection device is a device for automatic injection of Parkinson’s drug dissolution solution, which can effectively inject Parkinson’s drugs and other drugs. Most injection devices press the end of internal components To the skin of the patient at the injection site, the external component slides forward along the internal component to inject the drug into the patient. However, the external component squeezes the drug into the injection site during the injection process. The external component is prone to deformation and replacement. Medication trouble. [0003] The Chinese Patent Granted Announcement No. 201280043463.5 discloses a Parkinson's drug dissolving solution filtration and injection device. The syringe device includes a ...

[0002] Parkinson's drug dissolution solution filtration injection equipment is a device for automatic injection of Parkinson's drug solution solution, which can effectively inject Parkinson's drugs and other drugs. Most injection devices press the end of the internal parts To the patient's skin at the injection site, the outer part slides forward along the inner part to inject the drug into the patient's body, but the drug is squeezed into the injection site through the outer part during the injection process, and the outer part is easily deformed and replaced drug trouble

[0003] The Chinese patent with the authorized notification number 201280043463.5 discloses a dissolved solution filtering injection device for Parkinson's drug. , the sliding of the inner part and the outer part is relatively labor-saving, but in actual application, during the injection process of the syringe, the inner part and the outer part are easy to get stuck, which affects the injection effect of the syringe
