Description
Technical field
This utility model relates to the needle tubing shield sheath after a kind of double-vane transfusion needle is used.
Background technology
The double-vane transfusion needle is indispensable medical apparatus and instruments such as venous transfusion, blood sampling.As shown in Figure 1, existing double-vane transfusion needle comprises needle tubing 1, tube for transfusion 4, needle stand 2 and double-vane needle handle 3, and needle tubing 1 directly is bonded in the front end of needle stand 2, and tube for transfusion 4 is fixedly connected on the rear end of needle stand 2, and the fixedly connected double-vane needle handle 3 of the lateral margin of needle stand 2.In addition, needle tubing 1 also is not with needle tubing sheath 6 before using.
This double-vane transfusion needle takes out needle tubing sheath 6 earlier before using, and after venous transfusion finished, owing to relate to safety, this needle tubing sheath 6 was not suitable for reuse once more, thereby outside needle tubing is exposed to mostly.Medical personnel and patient are clearing up, are being subjected to needle stick injury easily when discarding, and cause pollution or infection.
Generation for fear of above-mentioned phenomenon, the applicant was on June 17th, 2002 in the applying date once, application for a patent for invention number is to disclose a kind of double-vane transfusion needle with safety device in 02112106.0, as Fig. 2, shown in 3, it comprises the needle tubing shield sheath 7 after a transfusion needle is used, before this sheath 7, latter two port 71,72 communicate, the length of this sheath 7 is greater than needle tubing 1 and length after needle stand 2 is fixedlyed connected, symmetry is offered two localized slotted eyes 73 of each wing root portion for double-vane needle handles 3 on the wall of the rear end of this sheath 7, and the forward position 731 initial front ports 71 that prolong described sheath 7 length directions difference joint-cutting to this sheath from each slotted eye 73 form two joint-cuttings 74.After transfusion finishes, as long as pulling tube for transfusion 4, just can drive needle stand 2 and enter sheath 7 front ports 71, the both wings root that impels double-vane needle handle 3 enters the joint-cutting 74 of sheath 7 automatically from the bottom 711 of " V " font bank 712 of both sides correspondence respectively, simultaneously needle tubing 1, needle stand 2 move after in sheath 7, both wings root until double-vane needle handle 3 snaps in the slotted eye 73, and slotted eye 73 stops double-vane needle handles 3 more backward or move forward, and this moment, needle tubing 1 was collected in the sheath 7.
Above-mentioned utility model can be safely after transfusion needle uses up, simply needle tubing is concealed in the sheath advantage simple in structure, highly versatile that this sheath has.But, not coming off out the joint-cutting 74 from this sheath 7 in order to make needle tubing 1, the slit requires less, and this makes that not only double-vane needle handle 3 sliding in joint-cutting 74 is relatively poor, the more important thing is; Difficulty has been brought to production and processing in less slit.Therefore, the difficult processing in slit is to reach requirement in the production, and scrappage is higher, and is difficult to satisfy the demand of producing in enormous quantities, and production cost is higher relatively.
The utility model content
The purpose of this utility model is to provide the needle tubing shield sheath after a kind of double-vane transfusion needle is used, and this sheath production and processing is convenient, and production cost is lower.
Needle tubing shield sheath after a kind of double-vane transfusion needle provided by the utility model is used, former and later two ports of this sheath communicate, the length of this sheath is greater than needle tubing and length after needle stand is fixedlyed connected, symmetry is offered two each localized slotted eyes of wing root portion for the double-vane needle handles on the wall of the rear end of this sheath, and the initial front port that prolongs described length direction difference joint-cutting to sheath from the forward position of each slotted eye, form two slits, it is characterized in that the upper and lower tape edge in each slit carries out inside and outside dislocation.
Above-mentioned needle tubing shield sheath, wherein, the ring limit of sheath front port is for to be formed by connecting by two symmetric " V " font banks, and the end of two joint-cuttings lays respectively at the bottom of each " V " font bank.
Above-mentioned needle tubing shield sheath, wherein, the both side edges of this sheath mount is the screw thread hair side.
Adopted above-mentioned technical solution, that is: the upper and lower tape edge with each slit on the sheath carries out inside and outside dislocation, has improved the situation of the slit difficult quality control in process of manufacture, and scrappage reduces, for production in enormous quantities provides the foundation, reduced production cost simultaneously.This utility model can be widely used on vacuum blood taking needle, the product of machine with similar forms such as blood taking needles.

The specific embodiment
Shown in Fig. 4～5, this utility model, it is the needle tubing shield sheath after the double-vane transfusion needle is used, former and later two ports 71,72 of this sheath communicate, the length of this sheath 7 is greater than needle tubing 1 and length after needle stand 2 is fixedlyed connected, symmetry is offered two localized slotted eyes 73 of each wing root portion for double-vane needle handles 3 on the wall of the rear end of this sheath 7, and from the forward position 731 of each slotted eye 73 initial prolong described sheath 7 length directions respectively joint-cutting form two slits 74 to the front ports 71 of sheath.Be characterized in: the last tape edge 741 in each slit 74, following tape edge 742 carry out inside and outside dislocation.
The ring limit of sheath front port 71 is for to be formed by connecting by two symmetric " V " font banks 712, and the end in two slits lays respectively at the bottom 711 of each " V " font bank.
The both side edges of this sheath mount is the screw thread hair side.
Referring to Fig. 2, after transfusion finishes, as long as pulling tube for transfusion 4, just can drive needle stand 2 and enter sheath 7 front ports 71, front port 71 impels each wing root portion of double-vane needle handle 3 to enter automatically two slits 74 of sheath 7 from the bottom 711 of two " V " font banks respectively, and simultaneously needle tubing 1, needle stand 2 move after in sheath 7, snaps in the slotted eye 73 until each wing root portion of double-vane needle handle 3, slotted eye 73 stops double-vane needle handles 3 more backward or move forward, and this moment, needle tubing 1 was collected in the needle tubing shield sheath 7.
In addition, the external diameter that is slightly less than elasticity tube for transfusion 4 can be adopted in the aperture of sheath 7 rear ports 72, make the external diameter close-fitting mutually of aperture and tube for transfusion 4 of the rear port 72 of sheath 7, thereby sheath front and back on the elasticity tube for transfusion were moved freely, can make sheath rest on optional position on the elasticity tube for transfusion again, when sheath is stayed the rear end of tube for transfusion 4, can carry out normal venous transfusion.
