Abstract
The utility model discloses a needle tube protective sleeve of a single-wing transfusion needle. A sleeve body and a base of the needle tube protective sleeve are connected with each other, a front port and a rear port of the needle tube protective sleeve are communicated with each other, a guide groove is arranged on the sleeve body, and a first safety fastener is disposed at the position, which is close to the base, of the guide groove. The needle tube protective sleeve is characterized by comprising a second safety fastener, and the second safety fastener is disposed between the first safety fastener and the guide groove. The second safety fastener is added on an existing needle tube protective sleeve and has an assisting function, accordingly, secondary protection of the single-wing transfusion needle is realized, potential safety hazards of the needle protective sleeve are reduced, and safety is further enhanced.
Description
Technical field
This utility model relates to the needle tubing protective sleeve, relates in particular to a kind of needle tubing protective sleeve of single wing transfusion syringe.
Background technology
Single wing transfusion syringe is indispensable medical apparatus and instruments such as venous transfusion, blood sampling, single wing transfusion syringe takes out the needle tubing sheath earlier before using, after venous transfusion finishes, owing to relate to safety, this needle tubing sheath is not suitable for reuse once more, thereby outside needle tubing was exposed to mostly, medical personnel and patient were subjected to needle stick injury easily in cleaning, when discarded, and caused and pollute or infect.
See also Fig. 1; the application's applicant was on August 5th, 2004; application for a patent for invention number is the needle tubing protective sleeve that discloses a kind of single wing transfusion syringe in 200410053444.8; before this needle tubing protective sleeve; latter two port one ' communicate; the safe buckle 3 ' that offers guide channel 2 ' on this needle tubing protective sleeve and link to each other with it; because the slit of this protective sleeve is the round about way shape; can be so that needle tubing comes off; thereby improved the little unmanageable unfavorable situation in slit in process of production; scrappage reduces; reduced production cost; but; because this sheath has only a safe buckle, therefore, can not realize second protection; in use, still there is certain potential safety hazard.
Summary of the invention
The utility model discloses a kind of needle tubing protective sleeve of single wing transfusion syringe, it has remedied the deficiency of the needle tubing protective sleeve of existing single wing transfusion syringe, by second protection, has further improved the safety of sheath.
The technical scheme that realizes above-mentioned purpose is: a kind of needle tubing protective sleeve of single wing transfusion syringe; body and base that this needle tubing protective sleeve links to each other; the front and back end ports of needle tubing protective sleeve communicates; offer a guide channel on the body; the close base position of this guide channel is provided with one first safe buckle; wherein, also comprise one second safe buckle, this second safe buckle is arranged between the described first safe buckle and the guide channel.
The needle tubing protective sleeve of above-mentioned single wing transfusion syringe, wherein, the bayonet socket direction of described second buckle is opposite with the bayonet socket direction of the described first safe buckle.
The needle tubing protective sleeve of above-mentioned single wing transfusion syringe, wherein, the both side edges of described base is the screw thread hair side.
The beneficial effects of the utility model are: this utility model is set up one second safe buckle on existing needle tubing protective sleeve; played auxiliary effect; realize the second protection of single wing transfusion syringe, reduced the potential safety hazard of needle tubing protective sleeve, further improved safety.
Description of drawings
Fig. 1 is the structural representation of existing a kind of needle tubing protective sleeve;
Fig. 2 is the structural representation of the needle tubing protective sleeve of a kind of single wing transfusion syringe of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further.
See also Fig. 2; there is shown the needle tubing protective sleeve of a kind of single wing transfusion syringe of the present utility model; body 1 and base 2 that this needle tubing protective sleeve links to each other; the front and back end ports 3 of needle tubing protective sleeve communicates; offer a guide channel 11 on the body 1; close base 2 places of this guide channel 11 are provided with one first safe buckle 12, also comprise one second safe buckle 13, and this second safe buckle 13 is arranged between the first safe buckle 12 and the guide channel 11.
The bayonet socket direction of the bayonet socket direction of second buckle 13 and the first safe buckle 12 is opposite.
The both side edges 21 of base 2 is the screw thread hair side, easy to use in being affectedly bashful of hands.
In this utility model; the first safe buckle 12 has played the main effect of the needle tubing (not shown) of blocking single wing transfusion syringe, and the second safe buckle of setting up 13 has played assosting effect; carry out second protection for needle tubing, improved the safety of using greatly.
Above embodiment is only for the usefulness that this utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
