Abstract
A pulley venous detaining needle is a venous detaining needle belonging to medical apparatus, with which one can operated vein indwelling catheterization with a single hand. The pulley venous detaining needle consists of puncture needle, puncture needle seat, detaining needle inserted in the puncture needle and detaining needle seat. The characteristic is that: a toothed pulley and a slide groove are on the puncture needle seat. Toothed slide block is at the detaining needle seat corresponding with the slide groove. The teeth of the pulley and the slide block are matched. Turn the pulley and the slide block can move back-and-forth to push the detaining needle to slide back and forth along the puncture needle. During vein indwelling catheterization, turn the pulley with one finger after puncturing. The detaining needle is pushed into the vein. The speed and the depth of the catheterization are controlled by the pulley.
Description
Technical field
This utility model relates to a kind of venous detaining needle that can singlehanded carry out the band pulley gear of Vein Tube operation, belongs to medical apparatus and instruments.
Background technology
Existing venous detaining needle basically by puncture needle, Paracentesis needle holder, and formed with remaining needle, the indwelling needle stand of puncture needle socket.When row vein was put pipe, the nurse will pass through fixedly Paracentesis needle holder of a hands after finishing the puncture action, and an other hand propelled is kept somewhere needle stand remaining needle is sent into blood vessel.This venous detaining needle is put two palmistry interworkings of pipe action need and is closed, and not only makes whole puncture and intubation process discontinuous, also is easy to wear out or deviate from blood vessel, has reduced the success rate of keeping somewhere, and effect is kept somewhere in influence.
Summary of the invention
Need the deficiency of bimanualness in order to overcome existing venous detaining needle, this utility model provides a kind of one-hand operation, finishes the remaining needle of Vein Tube by pulley gear.
The technical scheme that this utility model adopted: the pulley type venous detaining needle is made up of puncture needle assembly and the indwelling casing tube assembly that is socketed on the puncture needle assembly.The Paracentesis needle holder front end is puncture needle fixedly, and the rear end prolongation is a hand holding part, and a chute is set below Paracentesis needle holder inside, and inner and upper is provided with a band tooth pulley that can pivot.The remaining needle base rear end is provided with the band tooth slide block of corresponding chute.Chute, slide block, remaining needle, puncture needle are parallel relation, slide block just in time socket-connects with chute when keeping somewhere with the puncture needle socket, and the tooth on the slide block and the tooth on the pulley match rotary pulley, slide block can move forward and backward along chute, promotes remaining needle along sliding before and after the puncture needle.During Vein Tube, finish puncture action back, just the remaining needle forward impelling can be sent into blood vessel, reach the purpose of one-handed performance by a finger rotary pulley.
The beneficial effects of the utility model are: wholely put the pipe operating process and only need a hands to finish, simplified operating procedure, puncture and send pipe action to link up, be difficult for wearing out or deviating from blood vessel, improve the success rate of keeping somewhere.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Figure (1) is a pulley type remaining needle indwelling casing tube assembly side view.
Figure (2) is a pulley type remaining needle indwelling casing tube assembly front elevation.
Figure (3) is a pulley type retained needle puncture needle assembly side view.
Figure (4) is a pulley type remaining needle vertical section structural map.
Figure (5) is a pulley type remaining needle front elevation.
Figure (6) is the vertical section structural map of pulley type remaining needle embodiment.
Among the figure 1. remaining needle 2. keep somewhere needle stand and 3. be with the tooth slide block 5. fixing 6. 7. 8. 9. chute of pulley of Paracentesis needle holder of puncture needle of flank of end of 4. infusing
The specific embodiment
Figure (6) illustrated embodiment, select suitable vein, behind the sterilization local skin, tighten with the proficiency thumb that side skin is fixed vein under the vein, another hand-held remaining needle makes pinpoint inclined plane up, syringe needle becomes 30 degree JIAOCI to go into skin, use the forefinger rotary pulley after seeing blood back, and slide block moves forward along chute and promotes remaining needle and insert in the blood vessel along the puncture needle slip.With immobilization with adhesive tape indwelling casing tube assembly, withdraw from puncture needle and finish the Vein Tube operation.
Claims (2)
1. pulley type venous detaining needle, by puncture needle, Paracentesis needle holder, and with the remaining needle of puncture needle socket, keep somewhere needle stand and transfusion end and formed, it is characterized in that: Paracentesis needle holder is provided with a band tooth pulley and a chute, keep somewhere the band tooth slide block that the needle stand place is provided with corresponding chute, tooth on pulley and the slide block matches, rotary pulley, slide block can move forward and backward along chute.
2. the pulley type remaining needle of telling according to claim 1, it is characterized in that: the Paracentesis needle holder front end is puncture needle fixedly, and the rear end prolongation is a hand holding part, and below, Paracentesis needle holder inside be a chute, and the top is the band tooth pulley that can pivot; The remaining needle base rear end is band tooth slide block; Chute, slide block, remaining needle, puncture needle are parallel relation, slide block just in time socket-connects with chute when keeping somewhere with the puncture needle socket, and the tooth on the slide block and the tooth on the pulley match rotary pulley, slide block can move forward and backward along chute, promotes remaining needle along sliding before and after the puncture needle.
