Description
Technical field
The present invention relates to medical instruments field, and in particular to it is a kind of have shirk syringe needle mechanism insulin injection device and
Syringe needle.
Background technology
Diabetes are as a kind of rate disease occurred frequently characterized by hyperglycaemia, the method that there is no radical cure at present, noted to patient
It is a kind of preferable treatment method that insulin, which is penetrated, with symptom management.The injection tool category of insulin is various, injects pancreas in the world
The instrument of island element is mainly pocket insulin injection pen, medical worker and diabetes patient by using novopen and matched suitable
When injection needle, subcutaneous injection of insulin is completed according to quantity on time, so as to ensure the good control of blood glucose.But city for a long time
The connection of the novopen and the injection needle coordinated with it sold, entirely screw thread coordinate, in operation, it is necessary first to will
Injection needle is rotatably mounted on the pen core frame or built-in medicine core pipe of novopen front end, it is necessary to rotate again after the completion of injection
Injection needle is removed and is placed into appropriate container, rotation installation and removing operate during injection needle two it is cumbersome,
What particularly medical personnel and patient stabbed by mistake during removing injection needle is very risky.
Therefore, security and convenience angle that the present invention uses from insulin injection device are started with to above-mentioned prior art
It is improved, the defects of to overcome prior art to exist.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of insulin injection device and pin for having and shirking syringe needle mechanism
Head, install and shirk syringe needle facility fast, unload pin and do not contact syringe needle, reduce the risk for accidentally injuring operator, it is safe.
