Problems solved by technology

However, when the button-triggered auto-injector is used, it is easy for the user to press the injection button by mistake, causing the auto-injector to start outside the injection point, resulting in waste of injected drugs and medical risks due to wrong injection positions
The automatic injector with squeeze trigger will place the needle in the injection position during use. If the squeeze is not in place, the injection will not start and cause needle stick injury
After the injection is completed, some used medical devices need to be safely recycled, but how to ensure that the device is injected into other drugs for reuse after use, resulting in medical hazards

Abstract

The patent relates to the field of medical apparatus, in particular to a safe trigger for precise instruments. The safe trigger for precise instruments comprises a base, a push rod, a device connection sleeve and a trigger control sleeve, wherein the base and the device connection sleeve are movably connected to form a power cavity, the push rod is located in the power cavity, and the trigger control sleeve is connected with the base. Through the usage of devices of the safe trigger disclosed by the invention, operations of automatically triggering medicine injection and the like can be realized, associative operation steps and misoperations and medical negligence caused by operation steps can be reduced, and potential safety hazards caused by the situation that medical personnel wrongly use injectors to inject other medicines due to errors can be avoided.

Description

technical field [0001] This patent relates to the field of medical devices, in particular to a safety trigger for precision instruments. Background technique [0002] With the development of science and technology and population growth and aging, there is a lot of room for the development of medical devices. At present, a variety of automatic injection devices have been developed internationally. The device can be used to administer injections itself or to perform injections for others, requiring only triggering of the device. Many existing forms of autoinjectors are single use, but some autoinjectors also allow reloading of hypodermic cartridges. [0003] In an auto-injector, there are many different ways to trigger, including push-button triggers as well as squeeze triggers. The push-button trigger mode is that medical staff or patients press the button of the automatic injector to inject the medicine in the syringe into the human body. The extrusion trigger method is ...
