an administration set main body 6, its front end bending downwardly and being provided with an injection needle 23 inserted therein, wherein a butterfly slice 11 is extended outwardly from the lower edge of both sides of said administration set main body 6, and wherein the butterfly slice 11 on one side is provided on the inner edge with one or more engaging hook 62, and a semi-arc cover 63 is provided on front ends of both butterfly slices 11, while the rear end of the administration set main body 6 is connected with a hose 5; and
a needle thimble 7, sleeving on the injection needle 23 of the administration set main body 6.
When the one-time safe administration set structure according to this embodiment of the invention is used to carrying out the operation of drawing or injection, the needle thimble 7 on the administration set main body is simply removed, and the butterfly slices 11 are bended over, such that the medical practitioner can insert the injection needle 23 into the injection site of a subject to carry out the operation of drawing or injection. Thereafter, it is possible to avoid the risk of exposing the injection needle by simply bending downwardly the butterfly slices 11 on both sides, engaging one butterfly slice 11 on one side with the butterfly slice 11 on another side with the engaging hook 62, and, due to the engagement of butterfly slices 11 on both sides, semi-arc covers 63 at ends of the two butterfly slices 11 will cover together the injection needle 23, so as to avoid the occurrence of danger caused by exposure of the injection needle 23. Alternatively, no engaging hook 62 is provided on the butterfly slice 11 on one side of the administration set main body 6, but fasteners that can fastened with each other are provided at the bottom of two butterfly slices 11 or at the junction between two semi-arc covers 63. Furthermore, the structure according to the invention can be attached with the rear end of the hose 5 for connecting a test tube. Moreover, an outer annular jacket 27 made of elastic, flexible rubber material is provided to enclose the outer edge of the injection needle 23, such that, when the operation of drawing is carried out, the administration set in front of the hose 5 can be used to insert the injection site of a subject (such as, for drawing blood, ascitic fluid or other sampling work), whereupon the injection needle 23 of the structure of the invention is inserted into a test tube, and at this time, the outer annular jacket 27 will recede due to resistance from the test tube, and thereby lead the penetration of the injection needle into the test tube. As the drawing is complete, the medical practitioner can bend butterfly slice 11 on both sides downwardly and pulls correspondingly the injection needle 23 out of the test tube, such that, butterfly slices 11 on both sides can be fastened with each other through the engaging hook 62 and semi-arc cover 63 at the front end of the two butterfly slices 11 can enclose the injection needle 23, thereby danger from exposure of the injection needle can thus be avoided. Furthermore, the site on the outer annular jacket 27 punctured by the injection needle 23 can be forced to be seal closely by virtue of the elasticity of the outer annular jacket 27 so that the risk of infection by the exposure in the air of the blood remained on the injection needle can be avoided simultaneously.
Referring to FIG. 19, the one-time safe administration set structure according to the invention comprises:
an administration set main body 6, being provided with an injection needle 23 inserted therein, wherein a butterfly slice 11 is extended outwardly from the lower edge of both sides of said administration set main body 6, and wherein the rear end of the administration set main body 6 is connected with a hose 5;
a needle thimble 7, sleeving on the injection needle 23 of the administration set main body 6; and
a gaiter 61, sleeving on said administration set main body 6, wherein a slot 62 for the penetrating of the butterfly slice 11 is provided at the side edge of said gaiter 61, and wherein the front edge of said slot 62 is in a design of tapering with a stopping block 14 provided at a position near the rear side of said slot 62.
With the forgoing, before the use of the one-time safe administration set structure provided by the invention, the gaiter 61 presses against the butterfly slice 23 of the administration set main body 6 through a tapered design of its front opening such that the gaiter 61 can not move arbitrarily. When the one-time safe administration set structure according to the invention is used, the needle thimble is removed from the administration set main body 6 and then the operation of drawing or injection is carried out. After the operation is complete, the gaiter is pushed forwardly to let the butterfly slice 11 pass over the stopping block 14 at the opening 62 of the gaiter 61 so as to prevent the one-time safe administration set structure according to the invention form secondary use.
Referring to FIG. 20, in one embodiment of the one-time safe administration set structure according to the invention, the design of the bottom of said gaiter 61 is a sliding portion 63 that recesses upwardly. The sliding portion 63 has, at its rear side, a receptive portion 64 that recesses upwardly. Further, several stopping block are provided at the junction between the sliding portion 63 and the receptive portion 64. With this design, as the use of the one-time safe administration set structure according to the invention is complete, by simply pushing the gaiter 61 to the front edge of the administration set main body 6 and then pressing the gaiter downwardly, or bending the butterfly slice 11 upwardly, the butterfly slice 11 will be placed in the receptive portion 64, and can not release from the receptive portion due to the resisting of the stopping block 14, thereby it is possible to prevent the one-time safe administration set structure according to the invention from secondary use.
Referring to FIG. 21A, in one embodiment of the one-time safe administration set structure provided by the invention, an annular recess slot 65 is provided inwardly at a middle part of the administration set main body 6, while a gaiter 61 encloses the outer periphery of the administration set main body 6. A butterfly slice 11 is provided extending outwardly from the lower edge of one or two sides of said gaiter 61, respectively. A protruding rib 611 is provided on the inner edge of the gaiter 61 at a position corresponding to the annular recess slot 65. With this design of the one-time safe administration set structure provided by the invention, the direction of the slope over the tip of the injection needle 23 can be adjusted by the administration set main body 6 or the gaiter 61. Alternatively, several marks can be provided on the outer edge of the administration set main body 6 at places corresponding to the position of the slope over the tip of the injection needle 23 so that, when the injection needle 23 is to be inserted into the injection site of the subject and the main body 6 is rotated, the medical practitioner is able to notice the direction of the slope over the tip of the injection needle 23.
The one-time safe administration set structure provided by the invention has been described with reference to embodiments thereof. It should be noted that the one-time safe administration set structure provided by the invention can be applied to various syringes, such as, for example, specific syringe for hemodialysis, blood sampler, common needle type syringe or various adapting tube such as, transfusion tube.
