Fear, there are obstacles with closing.In addition, though Ye You mechanism has developed some combinations for avoiding allowing patient from seeing blood taking needle needle sword
Formula blood-taking device.But such modular appliance is generally existing that structure is complicated, it is difficult to popularize.
Utility model content
In order to solve the above-mentioned technical problem, the easy emitter of blood taking needle described in the utility model is to facilitate medical worker
Or experimenter slows down the terrified of person of blood collecting when taking a blood sample using how of pricking the hand.
The technical solution of the utility model is implemented:
The easy emitter of blood taking needle, comprising:
Rodlike shell, one end of the shell are exit end, and the exit end offers an opening, and the other end is for personnel
Hold the holding end that uses, the side of the holding end is provided with an operation port, in the shell between the exit end and holding end
Portion has a channel, and the enclosure interior is equipped with two positive stop lug boss；The inner wall of the shell is equipped with oblique protrusion；
Trigger assembly, including sliding block, the sliding block have the freedom of motion for moving to exit end from holding end along shell, should
There is sliding block a trigger board and the shoulder for supporting two positive stop lug boss, the trigger board to extend to the operation port,
The sliding block is equipped with push rod close to one end of the shell exit end；The sliding block has one to supply the oblique protrusion against only
Dynamic oblique sliding valve, the side of the oblique protrusion have a gap, which is used for the oblique protrusion that slips away for oblique sliding valve；
Spring is socketed on push rod, makes push rod toward the elastic pulling force of shell outgoing end motion, one end for providing one
Inner walls are connected to, the other end is connected to the sliding block；
Syringe needle is installed on push rod close to one end of the shell exit end.
Preferably, the easy emitter of the blood taking needle further includes a bumper bar, and the bumper bar is connected to the shell and opens
The cross through hole being equipped with, the axis of the cross through hole is vertical with channel, and the bumper bar, which is resisted against trigger board root, to be had
On the riser having.
Preferably, the easy emitter of the blood taking needle further includes a protection plug, and the protection plug sets the opening, is used for
It protects the quality of the syringe needle and avoids accidentally injuring.
Implement the beneficial effects of the utility model are:
1. the trigger board protruded using shell holding end operation port is pressed for user and is triggered, easy to operate, in syringe needle
It is hidden in enclosure interior, also effectively slows down the psychological pressure by proofer；
2. this has safety structure, when unused, the bumper bar is worn to be connect in cross through hole, bumper bar the utility model
It is resisted against the side of riser, lateral displacement does not occur for oblique sliding valve, therefore, trigger board is effectively prevent accidentally to be touched；Insure when extracting
After bar, user presses the trigger board, and oblique sliding valve will be staggered displacement with oblique protrusion, and from the gap of side
It slips away, sliding block moment is released, and under the effect of elasticity, syringe needle is released by push rod and is open, thus to the finger epidermis by proofer
It causes to puncture, meanwhile, shoulder possessed by sliding block is resisted against on two positive stop lug boss after the utility model triggers use, produces
Raw position limitation protection, avoids the further outgoing of syringe needle.
3. structure is simple, easy to implement, possess good industry prospect.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
