Description
Technical Field
The utility model relates to the field of medical equipment, specifically an electronic micropin syringe needle.
Background
The needle head on the market at present consists of a needle, a needle seat, a connector, a needle cylinder, a spring and a push rod, wherein the needle is fixed on the needle seat, the needle seat is installed at one end of the connector, the needle seat and the connector are arranged in the needle cylinder, the push rod is sleeved with the spring and penetrates through one end of the needle cylinder, and the other end of the connector is installed; when the needle is used, the push rod compresses the spring to move downwards to push the needle to pierce the skin so as to achieve the purpose of leading in, and when the spring moves upwards, the compressed spring rebounds to drive the needle to leave the skin, so that the needle reciprocates to finish the operation.
The structural design has the following defects and shortcomings:
1. the anti-backflow structure is not designed, and the backflow phenomenon caused by excessive liquid on the surface of the skin is treated;
2. when EO gas is used for sterilization, no gas inlet/outlet hole is reserved, and the sterilization effect is restricted.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electronic micropin syringe needle to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides an electronic micropin syringe needle, includes the cylinder that the level set up, and the inside cooperation of cylinder is provided with the connector, and the left end of cylinder is provided with the needle cap, the left end of connector is fixed and is provided with the needle file, and the right-hand member of cylinder is provided with the push rod, and the left end symmetry of connector is provided with two apertures, and cylinder cooperation aperture also is provided with the aperture, is provided with the oblate hole on the connector of aperture one side.
As a further aspect of the present invention: the push rod is inserted into the needle cylinder.
As a further aspect of the present invention: a spring is arranged between the push rod and the needle cylinder.
As a further aspect of the present invention: the left end of the push rod is connected with the right end of the connector in a matched mode.
As a further aspect of the present invention: the outer side of the needle cylinder is provided with a plurality of anti-skid bulges.
Compared with the prior art, the beneficial effects of the utility model are that: through the dislocation anti-reflux structure design of the symmetrical holes, no redundant effusion exists in the needle cylinder, liquid is prevented from flowing back to the interior of the electric microneedle through the cylinder wall, and the small holes of the needle cylinder can be used for forming gas convection, so that the effect of (EO gas) gas sterilization is ensured.
