Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and is especially a kind of with the disposable blood taking needle that launches function automatically.
Background technology
The department of hospital's chemical examination at present is when carrying out finger tip or ear-lobe blood sampling chemical examination, still directly use common blood taking needle mostly, in this case, blood taking needle is exposed in the air, the germy intrusion of meeting unavoidably in blood collection procedure, and because the patient can see whole blood collection procedure, so can bring certain psychological burden to the patient.Then there are defectives such as complex structure in several blood taking needles with the function of launching of announcing more, are difficult to be applied widely.
Summary of the invention
In order to overcome the deficiency of existing blood taking needle, this utility model provides a kind of disposable blood taking needle that launches function automatically that has, and this blood taking needle has characteristics such as simple in structure, easy to use.
The technical scheme that its technical problem that solves this utility model adopts is: disposable blood taking needle, its structure is by housing, propelling spring, needle body, syringe needle and pin medicated cap, propelling spring, needle body is connected successively with syringe needle and is arranged in the housing, one end of needle body joins by the end of propelling spring and housing, syringe needle is fixed on the other end of needle body and is arranged in the pin medicated cap that joins with needle body, the pin medicated cap stretches out from the other end of housing by the needle outlet of opening on housing, wherein, an end that joins with syringe needle on the needle body is provided with the triangle boss, housing is provided with the trigger mechanism that is made of trigger button and grab, the middle part of trigger mechanism is connected with housing, trigger button is arranged on an end of trigger mechanism, be arranged on needle body on the triangle boss mutually the grab of clamping be arranged on the other end of trigger mechanism.
The tow sides of trigger mechanism are provided with reinforcement.
When medical personnel utilize disposable blood taking needle of the present utility model to take a blood sample operation, at first the pin medicated cap is broken off with the fingers and thumb disconnected and taking-up, then the needle outlet of shell end is aimed at blood sampling site, after pressing trigger button, needle body drives syringe needle and will get with complete operation from needle outlet under the effect of propelling spring.
Disposable blood taking needle of the present utility model is compared with prior art, has following outstanding beneficial effect:
What (1) trigger mechanism adopted is the lever operation principle, makes trigger mechanism simple more, firm to the control of ejection process, makes that also the processing technology thereof of whole disposable blood taking needle is simpler, and cost is lower;
(2) after the use, needle body can't reset to preejection state, so, can guarantee the disposable use of blood taking needle, the cross infection of having avoided secondary to use;
(3) patient can directly not see blood collection procedure, has reduced patient's psychological burden.
