Description
Technical field
This utility model relates to the venous detaining needle in medical supplies, is specially a kind of venous detaining needle with safeguard function.
Background technology
Venous detaining needle, after completing puncture, needs the needle tubing of puncture to extract, only by the catheter retaining of softness in patient vessel, thus the medicinal liquid in the transfusion device be connected with remaining needle to be input in patient body by indwelling needle catheter.Existing remaining needle is after needle tubing is extracted, and needle tubing assembly departs from remaining needle and is directly exposed in environment, needle tubing sticks injuries easily occurs when medical personnel clear up it, adds the risk caught.In addition, existing retention needle tube syringe needle is ramp structure design, and this kind of syringe needle needs inclined-plane upwards in piercing process, and piercing process is restricted, and puncture wound surface is larger.
Utility model content
The purpose of this utility model is to provide a kind of venous detaining needle with safeguard function, and it can protect the needle tubing after puncture, prevents the generation of needle tubing sticks injuries.
For achieving the above object, the technical solution of the utility model is: a kind of venous detaining needle with safeguard function, comprise catheter block, be connected to the conduit of catheter block front end, the batching pig being arranged on catheter block inside and the needle tubing be applied in conduit and catheter block cavity, needle tubing afterbody is provided with needle stand, needle stand is positioned at the tail end of catheter block, needle stand is provided with holds needle handle, the afterbody of described catheter block is connected with protecting tube, protecting tube axially offers withdraw of the needle groove along pipe, for passing through for holding needle handle when pulling out needle tubing, at least two protective sheet are provided with in protecting tube inside, one end of protective sheet is connected on the inwall of protecting tube, the other end tilts towards the direction that needle tubing is extracted, and to the Axis Extension of protecting tube, the elongated end of each protective sheet is in the trend gathered, spring is provided with between protective sheet and protecting tube inwall, open gradually under the active force of needle stand in order to make each protective sheet elongated end gathering shape in needle tubing withdrawal process, and be blocked in the side of needle stand between each protective sheet by rear reinstatement completely at needle stand, and then needle tubing received completely and stays the inside of protecting tube.
Beneficial effect: this utility model is by arranging protecting tube at catheter block afterbody, make remaining needle in needle tubing withdrawal process, needle tubing is accommodated in protecting tube completely, and make to keep out of the way smoothly after protecting tube at needle tubing by the protective sheet that arranges in protecting tube and spring, and needle tubing is blocked in protecting tube, needle tubing is prevented to deviate from protecting tube, thus whole pull out in pin process and needle tubing discarded after needle tubing all can not be made to be exposed in external environment, effectively prevent the generation of needle tubing sticks injuries.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: 1, catheter block, 2, conduit, 3, batching pig, 4, needle tubing, 5, needle stand, 6, hold needle handle, 7, protecting tube, 8, protective sheet, 9, spring, 10, pin cap, 11, extension tube.
Detailed description of the invention
As shown in Figure 1, a kind of venous detaining needle with safeguard function, comprise catheter block 1, be connected to the conduit 2 of catheter block 1 front end, the batching pig 3 being arranged on catheter block 1 inside and the needle tubing 4 be applied in conduit 2 and catheter block 1 cavity, needle tubing 4 afterbody is provided with needle stand 5, needle stand 5 is positioned at the tail end of catheter block 1, needle stand 5 is provided with holds needle handle 6, the afterbody of described catheter block 1 is connected with protecting tube 7, protecting tube 7 is closed away from one end of catheter block 1, protecting tube 7 axially offers withdraw of the needle groove (not drawing in Fig. 1) along pipe, for passing through for holding needle handle 6 when pulling out needle tubing 4, withdraw of the needle groove is bar shaped gap slot, groove width adapts with the thickness holding needle handle 6, holding needle handle 6 stretches out in the outside of protecting tube 7 from withdraw of the needle groove, in needle tubing 4 withdrawal process, needle tubing 4 is accommodated in protecting tube 7 along withdraw of the needle groove by hand-held needle handle 6 of holding.At least two protective sheet 8 are provided with in protecting tube 7 inside, protective sheet 8 can be set to two or three, one end of protective sheet 8 is connected on the inwall of protecting tube 7, the other end tilts towards the direction that needle tubing 4 is extracted, and to the Axis Extension of protecting tube 7, the elongated end of each protective sheet 8 is in the trend gathered, spring 9 is provided with between protective sheet 8 and protecting tube inwall, open gradually under the active force of needle stand 5 in order to make each protective sheet elongated end gathering shape in needle tubing 4 withdrawal process, and be completely blocked in the side of needle stand 5 between each protective sheet 8 by rear reinstatement at needle stand 5, and then needle tubing 4 received completely and stays the inside of protecting tube 7.Wherein, the effect of protective sheet 8 prevents needle stand 5 from deviating from protecting tube 7.Protecting tube 7, protective sheet 8 and spring 9 can adopt medical plastic or elastomeric material to make.Can adopt between protecting tube 7 with catheter block 1 be threaded, buckle is connected or grafting, to make needle tubing 4 keeping out of the way completely after in protecting tube 7, protecting tube 7 can be separated from catheter block 1, facilitate patient fluid infusion, needle tubing 4 is accommodated in protecting tube 7 completely, its syringe needle can not be exposed in environment, not easily sticks injuries occurs.
Further, the syringe needle of described needle tubing 4 is prismatic syringe needle, and it is formed by three inclined-planes.Rhizoma Sparganii type needle point is sharp, and penetration Resistance is little, and blood back is rapid, can improve puncture success rate.Rhizoma Sparganii type piercing needle can adapt to the operation technique of different nurse, easy to operate, and puncture wound surface is little.
