Abstract
The utility model relates to the field of medical equipment, especially, relate to a thyroid gland pjncture needle. Including the puncture syringe needle, there is a syringe barrel at puncture syringe needle rear, and even there is a liquid collection bottle syringe below, and syringe barrel and liquid collection bottle are connected the intercommunication through catheter I, is equipped with the feed liquor check valve between syringe and the puncture syringe needle, the lateral wall of syringe front end be equipped with the exhaust hole and the hole matched with air exhaust one -way valve that exhausts, characterized by, liquid collection bottle's below and end still communicate and have catheter II catheter III, catheter I, catheter II, catheter III on respectively to having cock 10, cock 11, cock 12. Syringe below is connected with liquid collection bottle, when the thicker sample that is difficult to extraction or needs of bag liquid is more, can use the syringe to extract in succession, is equipped with the cock on the liquid trap, and the bag liquid that can take out the extraction at will can prevent that bag liquid from flowing backwards. Feed liquor check valve and air exhaust one -way valve on the syringe also have the effect that prevents the refluence of bag liquid.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of Thyroid puncture needle.
Background technology
Thyroid is the maximum endocrine gland of human body, is positioned at the front side of hypolarynx upper tracheal, can moves up and down when swallowing with throat.Thyroid gland thyroxin.Thyropathy is very common, in patient, women is more, when thyroid nodule and cyst, puncture needle must be used to obtain Pathologic specimen to thyroid nodule puncture diagnose, or extraction is carried out to capsule liquid treat, therefore Thyroid puncture needle is an important armarium, in existing Thyroid puncture needle, when the liquid in thyroid cyst is thin, Thyroid puncture needle is used to be easy to take out, during when the liquid thickness in thyroid cyst or to solid nodal-like enclosed mass, Thyroid puncture needle can not be used to take out because negative pressure is not enough, do not reach the object for the treatment of.Existing Thyroid puncture needle is when extracting capsule liquid, and tail end connects syringe, because syringe can only once extract, when capsule liquid comparatively thickness time often because negative pressure is not enough, and can not extract capsule liquid smoothly, or the sample size extracted is not enough, brings very large inconvenience to diagnosis and disease treatment.
Summary of the invention
For overcoming above-mentioned technical problem, this utility model provides one continuous several times can extract capsule liquid, and arbitrarily can take out the Thyroid puncture needle of capsule liquid.
Its structure of Thyroid puncture needle of the present utility model is as follows: comprise piercing needle, there is injector cartridge at piercing needle rear, liquid-collecting bottle is connected with below syringe, injector cartridge is connected by catheter I with liquid-collecting bottle, feed liquor check valve is provided with between syringe and piercing needle, the exhaust check valve that the sidewall of syringe front end is provided with steam vent and matches with steam vent, it is characterized in that, the below of described liquid-collecting bottle and end are also communicated with catheter II, catheter III, described catheter I, catheter II, respectively to there being cock 10 on catheter III, cock 11, cock 12.
The material of catheter I described in the utility model, catheter II, catheter III is politef.
Cock described in the utility model comprises A, plug handle, B plug body, C Kong Cao, D draw-in groove, E round platform.
The material of cock described in the utility model is politef.
The diameter of catheter described in the utility model and the volume ratio of liquid-collecting bottle are 0.01cm/mL.
The upper base radius of round platform described in the utility model: radius of going to the bottom: high is 2:3:3, and through hole is located at 2/3 place of cock, can better leakproof.
beneficial effect
This utility model has following beneficial effect: owing to being connected with liquid-collecting bottle below syringe, when capsule liquid is thicker be difficult to extract or the sample of needs is more time, syringe can be used to extract continuously, and liquid-collecting bottle is connected with cock, arbitrarily can take out the capsule liquid of extraction, also can prevent capsule liquid from flowing backwards, the feed liquor check valve on syringe and exhaust check valve, have this to act on too.Its reasonable in design, easy to use, swift to operate, there is significant practicality.
