Abstract
The utility model discloses a novel check blood drawing needle, which comprises a needle cylinder. A pintle is glidingly arranged in the needle cylinder; the other end of the needle cylinder is detachably provided with a needle head; and the needle cylinder is detachably provided with a base. When the novel check blood drawing needle is utilized, the needle tube can be supported by the base; compared with holding the needle tube by the hands of a medical worker, the method is simpler and more convenient when in operation and has higher precision, and moreover, the needle head can be effectively prevented from pricking the tissues around vessels or puncturing the skins, and thereby, the pain of a patient is relieved; due to the fact that the base can be detachably arranged in the needle cylinder, the base can be repeatedly used and the medical treatment cost can not be increased.
Description
Technical field
This utility model relates to a kind of medical apparatus technical field, relates in particular to a kind of bloodletting instrument of checking blood to use.
Background technology
When testing blood drawing to patient at present, used blood drawing pin mostly is disposable blood drawing pin greatly, and such blood drawing pin is lighter, after penetrating patient's blood vessel, need control fixedly syringe on the other hand, another pulls moving piston, to medical personnel's specification requirement than higher, inconvenient operation so not only, and two hands have slightly cooperate bad, syringe needle promptly might be pricked circumvascular tissue, even wears out skin, brings big painful to the patient.
The utility model content
Technical problem to be solved in the utility model provides a kind of novel check that can fix the blood drawing pin easily blood drawing pin.
For solving the problems of the technologies described above, the technical solution of the utility model is: novel check comprises syringe with the blood drawing pin, is slidingly fitted with pintle in the described syringe, and the other end of described syringe is installed with syringe needle, and base detachably is installed on the described syringe.
As a kind of optimized technical scheme, described base is trapezoidal, and the upper bottom surface of described trapezoidal base is the cambered surface of indent, and the shape of described cambered surface and described syringe is complementary.
Owing to adopted technique scheme, novel check comprises syringe with the blood drawing pin, is slidingly fitted with pintle in the described syringe, and the other end of described syringe detachably is equipped with syringe needle, and base detachably is installed on the described syringe; When utilizing novel check with the blood drawing of blood drawing pin, can rely on base to support needle tubing, compare the both hands that rely on medical personnel and grip needle tubing, this method operates easier, and precision is higher, and can also prevent effectively that syringe needle from pricking circumvascular tissue or wearing out skin, alleviate patient's misery, because described base is removably installed on the described syringe, base can be reused, and can not increase medical treatment cost.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Fig. 2 is the profile of base;
Among the figure: 1. syringe needle, 2. syringe, 3. pintle, 4. base.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As depicted in figs. 1 and 2, novel check comprises syringe 2 with the blood drawing pin, is slidingly fitted with pintle 3 in the described syringe 2, and the other end of described syringe 2 detachably is equipped with syringe needle 1, on the described syringe 2 base 4 is installed detachably.Described base 4 is trapezoidal, and the upper bottom surface of described trapezoidal base 4 is the cambered surface of indent, and the shape of described cambered surface and described syringe 2 is complementary.
During use, the cambered surface cover of base 4 indents is received on the described syringe 2, medical personnel are when drawing blood to the patient, can rely on base 4 pin of will drawing blood to fix, fix compared to the dependence both hands that medical personnel are traditional, this method operation is easier, and precision is higher, can prevent effectively that syringe needle from pricking circumvascular tissue or wearing out skin, alleviate patient's misery.This base 4 is dismountable, thus can be recycling, can not increase medical treatment cost.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in the foregoing description and the description just illustrates principle of the present utility model; under the prerequisite that does not break away from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
All are from design of the present utility model, and the reconfiguration of having done without creative work all drops within the protection domain of the present utility model.
