Abstract
The utility model relates to a closed type safety vein retained needle which mainly comprises a sleeve pipe of the retained needle, a sleeve pipe seat, a puncture needle pipe, a connecting pipe and a transfusion three-way joint assembly, wherein the back end of the sleeve is connected with the sleeve pipe seat and a sealing plug is arranged in the sleeve pipe seat. The puncture needle pipe is inserted through the sealing plug in a closed mode to be penetrated in the sleeve pipe of the retained needle. The sleeve pipe seat is sideways connected with the transfusion three-way joint assembly through the connecting pipe. The back part of the sleeve pipe seat is provided with a protective sleeve of the puncture needle pipe, which is composed of a middle rotary sleeve and a back sleeve. A sliding guide groove of a needle handle wing sheet is axially arranged on the walls of the middle rotary sleeve and the back sleeve. When the puncture use is completed and medical staff withdraw a puncture needle pipe assembly of the retained needle, the puncture needle pipe can be completely sheathed in the protective sleeve and the safe disposal can be realized. The possibility that the medical staff are accidentally damaged by needles to infect diseases can be avoided.

Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of closed high-safety needle staying on vein.
Background technology
We know, venous detaining needle is a kind of medical apparatus and instruments that is used for the venous indwelling transfusion, it mainly includes remaining needle sleeve pipe, casing seat, puncture needle tubing, connecting leg, transfusion three way cock assembly, the sleeve pipe rear end is connected with casing seat, sealing-plug also is housed in the casing seat, the puncture needle tubing was inserted sealing-plug hermetically, was positioned at the remaining needle sleeve pipe, and the casing seat side direction is connected with transfusion three way cock assembly by connecting leg.After medical personnel use venous indwelling at the patient's vein vascular puncture, need the puncture needle tubing is extracted from casing seat rear end and remaining needle sleeve pipe, comparatively softish sleeve portion is kept somewhere in the patient's vein blood vessel, carried out continuously to the patient or transfusion discontinuously by the remaining needle sleeve pipe.Because the needle point of puncture needle tubing is extremely sharp, needle tubing is extracted back needle tubing and tip portion from the sleeve pipe of remaining needle exposed fully, very easily causes to accidentally injure and catch, and the healthy of medical personnel constituted a threat to.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, can cover the puncture needle tubing of from the remaining needle sleeve pipe, extracting effectively, avoid the high-safety needle staying on vein of its closed that medical personnel are damaged.
The technical scheme in the invention for solving the above technical problem is: a kind of closed high-safety needle staying on vein; mainly include remaining needle sleeve pipe, casing seat, puncture needle tubing, connecting leg, transfusion three way cock assembly; the sleeve pipe rear end is connected with casing seat; sealing-plug also is housed in the casing seat; the puncture needle tubing was inserted sealing-plug hermetically; in the remaining needle sleeve pipe; the casing seat side direction is connected with transfusion three way cock assembly by connecting leg, it is characterized in that: the casing seat rear portion is provided with the puncture needle of being made up of middle turning set and back cover and guarantees sheath.
Both sides are provided with fin on the needle handle of puncture syringe rear end described in the utility model, are axially arranged with fin slide-and-guide groove on middle turning set and the back jacket wall.
Casing seat described in the utility model rear end is provided with mouth of connecting trough, and middle turning set is provided with a connection bump that matches with the casing seat mouth of connecting trough.
Closed high-safety needle staying on vein described in the utility model, its needle handle both sides are the arcuated fin piece of holding up, and the vertical bar projection is arranged on the fin.The cover inner wall at end is provided with annular protrusion behind this utility model, and the needle handle rear end is provided with the elasticity boss of band cross notch accordingly.
This utility model is guaranteed sheath owing to be connected with puncture needle at the casing seat rear portion; against existing technologies; medical personnel are when extracting retained needle puncture needle tubing assembly; the puncture needle tubing can be fully by upper shield in protective sleeve; realized safe disposal, avoided medical personnel to be accidentally injured by pin and catch may.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that part assemblies such as this utility model protective sleeve are disassembled sketch map.
1. sheaths among the figure, 2. sleeve pipe, 3. casing seat, 4. sealing-plug, 5. connecting leg, 6. clip, 7. threeway, 8. calparine cap, 9. end cap, 10. puncture needle tubing, 11. needle handles, turning sets in the middle of 12., 13. back covers.
The specific embodiment
As seen from Figure 1, a kind of closed high-safety needle staying on vein of this utility model mainly includes remaining needle sleeve pipe 2, casing seat 3, puncture needle tubing 10, connecting leg 5, transfusion three way cock assembly etc.Sheath 1 is arranged outside the sleeve pipe 2, sleeve pipe 2 rear ends are connected with casing seat 3, casing seat 3 back segment inner chambers also are equipped with sealing-plug 4, puncture needle tubing 10 was inserted sealing-plug 4 hermetically, it is through whole remaining needle sleeve pipe 2, casing seat 3 lateral branching pipes are connected with transfusion three way cock assembly by connecting leg 5, be that connecting leg 5 one ends are communicated with remaining needle sleeve pipe 2 by casing seat 3, the other end connects threeway 7, threeway 7 two outlets in addition has nipple and calparine cap 8 and end cap 9 to spin, and medicinal liquid enters threeway 7 by calparine cap 8, the connecting leg 5 of flowing through, prop up through casing seat 3 side direction and mouthful to enter the casing seat ante-chamber and flow to sleeve pipe 2, enter vein blood vessel at last.When carrying out two kinds of medicinal liquid transfusions,, connect other transfusion apparatus and get final product as long as screw off end cap.
It can also be seen that by Fig. 1 and Fig. 2 this utility model casing seat 3 rear portions are provided with by middle turning set 12 and back cover 13 puncture needles of forming guarantees sheath.Described casing seat 3 rear ends are provided with mouth of connecting trough 3a, and middle turning set 12 is provided with a connection bump 12a who matches with the casing seat mouth of connecting trough.Puncture needle tubing 10 tail ends are fixed on the needle handle 11, and it passes sealing-plug 4 and is inserted in the sleeve pipe 2.Both sides are provided with fin by planar slide bar 11a on the needle handle 11 of puncture syringe rear end described in the utility model, and it is the arcuated fin piece 11b that holds up, and the vertical bar projection is arranged on the fin.Like this, match, and curved surfaces there is the vertical bar projection, is convenient to the strength of controlling puncture and extracting with medical personnel's finger surface arc.Be axially arranged with fin slide-and- guide groove 12b and 13a on middle turning set 12 and back cover 13 walls.Cover 13 inner wall at end are provided with annular protrusion 13b behind this utility model, and needle handle 11 rear ends are provided with the elasticity boss 11c of band cross notch accordingly.Middle turning set 12 and back cover 13 tight fit sockets.
