Detailed description of the invention
Refer to Fig. 1, it is first embodiment of the invention axonometric chart, and safe needle sleeve 1 is protected in outside a butterfly pin group 2 in order to fit.The present invention treats that safe needle sleeve 1 is by plastic material ejection formation substantially, the simple structure that intermediate plate 11,12 and the coupling block 13 of the following stated especially of the present invention are combined jointly is practical, be easy to again manufacture, utilize the simple structure that the elastic held power effect of coupling block 13 and intermediate plate 11,12 are combined into one, reach the safe and practical characteristic that safe needle sleeve should possess, and break through the technical bottleneck that the complicated structure of past safe needle sleeve is not easy to manufacture, just structural feature of the present invention is described as follows below.
Safe needle sleeve 1 has a coupling block 13, one first intermediate plate 11 and one second intermediate plate 12, coupling block 13 has the infusion connection tube 3 that a through hole 131 can connect for butterfly pin group 2 to be passed through, through hole 131 both sides of coupling block 13 extend the first intermediate plate 11 and the second intermediate plate 12 respectively outward, make coupling block 13 and the first intermediate plate 11 and the second intermediate plate 12 integrally formed, wherein the first intermediate plate 11 extends one first and sticks up end 111 in end toward outside, namely first intermediate plate 11 other end is connected on a coupling block 13 with the second intermediate plate 12 is common corresponding, and the second intermediate plate 12 correspondence first stick up end 111 in its end toward another outside extend one second and stick up end 121, make safe needle sleeve 1 stick up end 111 and second in first to stick up between end 121 and be formed with a needle guard mouth 14 opened, to facilitate the following operation of butterfly pin group 2 freely.
First intermediate plate 11 is respectively provided with a recess groove 112 in its both sides, bottom surface, and the position that the second intermediate plate 12 corresponds to recess groove 112 is respectively provided with a block lobe 122, and the first intermediate plate 11 is formed with one between two intermediate plates after jointly connecting coupling block 13 with the second intermediate plate 12 separated guide channel 151,152 into two sections, front and back by block lobe 122.
Guide channel 151,152 between first intermediate plate 11 with the second intermediate plate 12 communicates in outside, and interconnects with the guide hole 131 running through coupling block 13.
Butterfly pin group 2 has a solid needle tubing 21, Gu needle tubing 21 one end is provided with a syringe needle 22, infusion connection tube 3 is connected to the other end of its solid needle tubing 21 of butterfly pin group 2, and solid needle tubing 21 is extended with a fin 23 toward side.Infusion connection tube 3 after connection butterfly pin group 2, then passes coupling block 13 through guide hole 131.
Refer to shown in Fig. 2, it is schematic perspective view when first embodiment of the invention injection uses, when injection uses, grip fin 23 butterfly pin group 2 is pulled out to needle guard mouth 14, the infusion connection tube 3 making it connect can be drawn out in the lump outside safe needle sleeve 1 with butterfly pin group 2 and use after guide hole 131 with guide channel 151,152, as shown in Figure 4.
Refer to shown in Fig. 3, it is the schematic perspective view after first embodiment of the invention injection use, after injection uses, grip the needle guard mouth 14 that butterfly pin group 2 is retracted safe needle sleeve 1 by the infusion connection tube 3 passing guide hole 131 rear, make the fin 23 of butterfly pin group 2 first through the guide channel 151 of leading portion, enter the guide channel 152 of back segment after by block lobe 122.
The restriction and cannot driving in the wrong direction that the fin 23 entered in back segment guide channel 152 is subject to block lobe 122 is moved toward the direction of the guide channel 151 of leading portion again, be able to the syringe needle 22 of butterfly pin group 2 to be placed on as shown in Figure 5 between the first intermediate plate 11 of safe needle sleeve 1 and one second intermediate plate 12, avoid the danger stabbed by syringe needle 22, and syringe needle 22 cannot be used once again, by safe needle sleeve 1 can guarantee butterfly pin group 2 use on safety and prevent syringe needle cleaned after two degree by the disadvantage used.
Safe needle sleeve 1 separately can coordinate butterfly pin group 2A to use as shown in Fig. 6 and Fig. 7, butterfly pin group 2A and butterfly pin group 2 difference are only that the solid needle tubing 21 of butterfly pin group 2A is respectively extended with fin 231A, a 232A toward both sides, all the other structures are all identical with butterfly pin group 2, therefore are marked with same-sign and economize its related description.
After injection uses, grip pass guide hole 131 rear infusion connection tube 3 by butterfly pin group 2A to pull back the needle guard mouth 14 of safe needle sleeve 1, the restriction and cannot driving in the wrong direction making fin 231A, the 232A entered in back segment guide channel 152 be subject to block lobe 122 is moved toward the direction of the guide channel 151 of leading portion again, is able to be placed on as shown in Figure 7 by syringe needle 22 between first intermediate plate 11 and one second intermediate plate 12.
Safe needle sleeve 1 is when collocation butterfly pin group 2 or butterfly pin group 2A use, blood sampling can be carried out in infusion connection tube 3 rear connection one blood sampling cylinder 4 and a blood taking tube 5 as shown in Figure 8 to use, also can carry out transfusion in infusion connection tube 3 rear connection one drop Storage Cup 6 and a drop storage bottle 7 as shown in Figure 9 and use.
Refer to Figure 10, it is second embodiment of the invention axonometric chart, and safe needle sleeve 1A is in order to be sleeved on outside a butterfly pin group 2.
Safe needle sleeve 1A has one first intermediate plate 11A and one second intermediate plate 12A, first intermediate plate 11A extends one first and sticks up end 111A in one end toward outside, and the second intermediate plate 12A correspondence first stick up end 111A in its end toward another outside extend one second and stick up end 121A.
First intermediate plate 11A is respectively provided with a recess groove 112A in its both sides, bottom surface, and the position that the second intermediate plate 12A corresponds to recess groove 112A is respectively provided with a block lobe 122A.
The first intermediate plate 11A other end is connected with one first connection part 131A, first connection part 131A has one first connection slot 1311A, the corresponding first intermediate plate 11A of second intermediate plate 12A is provided with the second connection part 132A of a shape and the first connection part 131A complementation, and the corresponding first connection slot 1311A of the second connection part 132A is provided with one second connection slot 1321A.
First intermediate plate 11A mat itself and the first connection part 131A are connected in the second connection part 132A of the second intermediate plate 12A, make safe needle sleeve 1A stick up end 111A and second in first to stick up between the 121A of end and be formed with a needle guard mouth (not shown), and the first intermediate plate 11A and the second intermediate plate 12A is formed with one between two intermediate plates is separated guide channel (not shown) into two sections, front and back by block lobe 122A.
Guide channel between first intermediate plate 11A with the second intermediate plate 12A communicates in outside, and the perforate jointly formed in the first connection slot 1311A and the second connection slot 1321A that is connected, for mat pulls dynamic infusion connection tube 3, butterfly pin group 2A is retracted the needle guard mouth of safe needle sleeve 1A, the restriction and cannot driving in the wrong direction making the fin 23 entered in back segment guide channel be subject to block lobe 122A is moved toward the direction of the guide channel of leading portion again, and has effect identical with the first embodiment.
Safe needle sleeve in the present invention can be consolidated with any type of butterfly pin assembly trap because of it, traditional butterfly pin group can be made need not to do any change under, just directly can coordinate the safe needle sleeve in the present invention, the present invention thus can be made to have compatible and suitability person widely.
