Abstract
The utility model provides an adjustable venous transfusion special needle, which structurally comprises a needle head, wherein a liquid outlet is formed at the front end of the needle head; a three-way pipe is in threaded connection with the rear end of the needle head; a control switch is arranged on the three-way pipe; a fixing wing and a rotary wing are further arranged on the needle head; and the rotary wing can rotate 360 degrees around the needle head. Compared with the prior art, the adjustable venous transfusion special needle has the characteristics of reasonable design, simple structure, convenience for use and the like; and as the adjustable venous transfusion special needle is strong in practicability, wide in application range and lower in cost, the adjustable venous transfusion special needle can be used as a venous transfusion puncture needle for internal medicine and surgical department, and is easy to popularize.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of simple in structure, adjustable venous transfusion special needle.
Background technology
Clinically at present, venous transfusion be must experience stage, some transfusion sometimes requires at a slow speed, quantitatively, the carrying out of constant speed, the transfusion difficulty is larger, in hospital, adopts manual propelling in the time of most at present, will bring considerable trouble and problem like this.Such as infusion needle is fixing not firm, easily drift about, and then the blood back phenomenon occurs, can also cause the obstruction of transfusion needle point, can't continue transfusion; The unstable easy blood vessel to the patient of syringe needle causes damage.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of adjustable venous transfusion special needle that prevents that needle point from stopping up, stability is strong is provided.
The technical solution of the utility model realizes in the following manner, this adjustable venous transfusion special needle, its structure comprises syringe needle, described syringe needle front end offers liquid outlet, the syringe needle rear end tee T that has been threaded, be provided with gauge tap on this tee T, also be provided with fixed-wing and rotary wings on syringe needle, described rotary wings can be done 360 degree rotations around this syringe needle.
As preferably, offer side opening on the relative syringe needle sidewall of described liquid outlet.
The beneficial effect that this utility model compared with prior art produces is:
The characteristics such as that adjustable venous transfusion special needle of the present utility model has is simple in structure, easy to use, stability is strong are provided with side opening, can effectively solve transfusion needle point clogging; Be provided with adjustable rotary wings, prevent on needle point and float, successful during transfusion is connected firmly; Be provided with tee T, can expand use; Cost is lower, and is applied widely, can be used as M-C venous transfusion puncturing needle and uses, and is easy to promote.
