Abstract
The utility model provides an I-shaped finger blood taking needle. The I-shaped finger blood taking needle comprises a needle cylinder, wherein an upper cover is arranged at the top of the needle cylinder, a button is arranged in the middle of the upper cover in a sleeved mode, the bottom end of the button is connected with the top end of an elastic device arranged inside the needle cylinder, a needle body is arranged at the bottom end of the needle cylinder in a sleeved mode, and the bottom end of the elastic device makes contact with the tail end of the needle body. The I-shaped finger blood taking needle is simple in structure, is low in cost, and adjusts the taken blood concentration by using syringe needles of different specifications and baffles of the syringe needles, thereby reducing injury to a patient, shortening the healing time of a wound, and avoiding cross infection.
Description
Technical field
This utility model relates to the disposable blood taking needle that hospital uses, and is specifically related to I-shaped finger blood-taking pin.
Background technology
Doctor, in the time taking a blood sample to patient finger, adopts disposable blood taking needle to sting patient's finger mostly, and the depth of finger wound only determines with doctor's experience, be not is deeply exactly shallow, has caused certain injury to patient.Because if wound is shallow, go out insufficiency of blood or not hemorrhage, must sting again once, cause the unnecessary pain of injury to patient; If wound is dark, amount of bleeding is much of that, but causes the long problem of healing time to patient, and has strengthened the probability infecting.
Novel ejection blood collection needles exists again pricker steadiness poor, and complex manufacturing technology hinders the problems such as operator's sight line.If application number is CN200820144792.X, the adjustable blood collecting pen of a kind of depth of needling is disclosed, by the elastic force effect of the movable piston ejector ram, ejector piston of installing in pen container, blood taking needle is ejected.Although this device can load and unload blood taking needle and reuse, but its complex structure, and realize by specific pull bar owing to attending class, even if this blood taking needle was used, also can again attend class, once therefore operator ignore, can cause blood taking needle Reusability and cause the security incident of cross infection; Because blood collecting pen is often provided with the cap for brush, handling blood taking needle is cumbersome simultaneously.
Summary of the invention
In order to overcome problems of the prior art, this utility model provides a kind of simple in structure, easy to operate I-shaped finger blood-taking pin, can control the depth of finger blood-taking wound.
For achieving the above object, this utility model has adopted following technical scheme: I-shaped finger blood-taking pin, comprise syringe, and described syringe top is provided with upper cover, described upper cover intermediate sleeve is provided with button, and the bottom of described button is connected with the top of the elastic device of being located at syringe inside; The bottom of described syringe is arranged with needle body, and the bottom of described elastic device contacts with the tail end of described needle body.
Further, the backshank that described needle body comprises syringe needle, matches with syringe bottom internal diameter, the backshank that described needle body comprises syringe needle, matches with syringe bottom internal diameter, is provided with the baffle plate vertical with they axis between described backshank and syringe needle.
Further, described elastic device is spring.
Upper cover of pin case in I-shaped finger blood-taking pin of the present utility model and the baffle plate on needle body have formed " work " font, are provided with the middle button bottom of upper cover and are connected with spring top, and the end of spring contacts with the backshank of needle body.Wherein syringe needle design plurality of specifications, as 2 millimeters, 3 millimeters, 4 millimeters, 5 millimeters, with time select the specification of syringe needle according to person of blood collecting's skin conditions, the bottom by it from syringe packs in syringe, its baffle plate just in time blocks the bottom face of syringe.As will be carried out needle exchange time, by pressing button manually, by the elastic reaction of spring, syringe needle is supported out, then change new needle body.And in the time of blood sampling, due to the existence of baffle plate, thereby prevented the pollution of blood to syringe bottom face, prevent cross infection each other; In addition, by baffle plate, the extruding of finger has been controlled to the degree of depth that syringe needle thrusts finger, thereby reduced wound healing time.
So the utlity model has following beneficial effect:
1, this utility model is simple in structure, and production cost is low; Utilize pressure principle to change syringe needle, saved use cost.
2, utilize the syringe needle of different model to regulate the blood sampling degree of depth, and utilize baffle plate further to control the blood sampling degree of depth, thereby reduce the injury to patient, reduce the healing time of wound surface.
3, utilize the pollution of the anti-Hemostatic Oral Liquid of baffle plate to syringe bottom face, avoided cross infection.
Brief description of the drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the structural representation of needle body.
In figure: 1-button, 2-upper cover, 3-syringe, 4-spring, 5-needle body, 5-1 syringe needle, 5-2 baffle plate, 5-3 backshank.
Detailed description of the invention
As shown in Figure 1, 2, I-shaped hands blood taking needle, comprises syringe 3, and syringe 3 tops are provided with upper cover 2, and upper cover 2 intermediate sleeve are provided with button 1, and the bottom of this button 1 is connected with the top of the spring 4 of being located at syringe 3 inside; The bottom of described syringe 3 is arranged with needle body 5, needle body 5 comprise syringe needle 5-1, with the backshank 5-3 that syringe bottom internal diameter matches, between described backshank 5-3 and syringe needle 5-1, be provided with the baffle plate 5-2 vertical with they axis; The bottom of described spring 4 contacts with backshank 5-3, and baffle plate 5-2 is positioned at the outside of syringe 3, by the extruding of button 1, by spring 4, backshank 5-3 is extruded to syringe 3, thereby conveniently needle body 5 is changed.Baffle plate 5-2 has prevented the pollution of blood to syringe bottom face, has prevented patient's cross infection each other; In addition, by the syringe needle 5-1 and the baffle plate 5-2 that select different size, the extruding of finger has been controlled to the degree of depth that syringe needle 5-1 thrusts finger, thereby reduced wound healing time.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
