Description
Technical Field
The utility model relates to a medical apparatus, in particular to a medical injector.
Background
In general, a disposable syringe is used in order to prevent secondary infection and ensure the accuracy of an experiment, and a disposable needle is combined with a disposable syringe body and classified as infectious waste after use to prevent reuse.
However, in the case of a precision syringe that is precisely manufactured to precisely inject medicine, unlike a general syringe, the cost increases each time a new syringe is replaced. To reduce this, the precision syringe may be reused after sterilization, but secondary infections may occur or errors in experimental data may occur.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a medical injector.
The utility model discloses a realize above-mentioned purpose and the technical scheme who takes does:
the utility model provides a medical injector, this injector includes syringe needle and syringe body thereof, syringe body and syringe needle between be connected through setting up coupling assembling, coupling assembling include the one end of syringe body and set up the connection boss, the connection boss on set up the injection through-hole that is linked together with syringe body inner chamber, the injection through-hole on wear to be equipped with the connecting piece, the connecting piece on be provided with the intercommunicating pore that communicates each other with syringe body and syringe needle, the one end of connecting piece wear to establish with the injection through-hole in, the other end sets up syringe needle connecting portion, its middle part blocks the ring through setting up and is connected the boss and offset to through setting up on fixed cover locking and the connection boss, fixed cover on set up the perforation, syringe needle connecting portion pass perforation and syringe needle cup joint mutually.
As a further improvement, the fixed cover is connected with the connecting boss by arranging internal and external threads.
As a further improvement, the injector body comprises a syringe and a core rod arranged in the syringe.
As a further improvement, the connecting piece and the blocking ring are both made of rubber materials.
As a further improvement, a plurality of contact suction grooves are arranged on the contact surface of the blocking ring.
The utility model discloses the syringe body is connected with disposable syringe needle through coupling assembling, not only can maintain the precision of syringe main part but also can change disposable syringe needle simultaneously. The disposable syringe needle can be replaced by uncomplicated sterilization treatment in the experiment, so that the pollution is reduced to the minimum, and the utility model discloses the syringe body can be used simultaneously with the disposable syringe needle of different specifications and sizes through the connecting component.
