Description
Technical field
This utility model relates to field of medical device, specifically a kind of anesthetic needle.
Background technology
When performing the operation, need to beat anesthetic needle at operative segment, anesthetic needle of the prior art cannot complete narcotic quantitative conveying, when therefore needing again to input in operation process, need assistant again to extract anesthetis, then carry out inputting again extremely bothering, narcotic input quantity of the prior art relies on eye observation simultaneously, therefore can produce error unavoidably, inputted at least in operation process patient can produce pain, inputted and patient can be caused at most numb for a long time.But also there is other weak points: syringe needle is connected very insecure with syringe, when extracting needle guard, easily taking out of also suitable for syringe needle, use inconvenience, and syringe needle Connection Block smoother being tiny, not easy to operate during replacing.
Utility model content
The purpose of this utility model is to provide a kind of anesthetic needle, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of anesthetic needle, comprise syringe, piston head is equipped with in described syringe, piston head is connected with columniform piston rod, piston rod is provided with force side away from one end of piston head, syringe is provided with syringe needle away from one end of piston rod, on the shaft of described piston rod, movable sleeve is provided with positioning sleeve, the shaft of piston rod is axially provided with locating slot, the outer surface of positioning sleeve is provided with the locating hole coordinating locating slot, locating hole female thread is connected with lock screw, and lock screw is against in locating slot through after locating hole; Described syringe needle comprises syringe needle tube and Connection Block, Connection Block comprises the needle tubing seat, the profile that are fixedly connected sequentially and is the mount pad of hex nut shape and is provided with externally threaded connection base, the syringe needle junction inwall of syringe is provided with and the female thread being connected base and adapting; The outer surface of described syringe is provided with loose collar, and the outer circumference surface of loose collar is symmetrically arranged with two finger rings, is combined with screw between loose collar and syringe, described screw is symmetrically arranged with two; The leading section of described syringe is also provided with annular flange flange.
As further program of the utility model: described needle tubing seat, mount pad and connection base are one-body molded, connect on base and be also set with sealing ring.
As this utility model further scheme: the shaft of described piston rod is axially provided with scale.
As this utility model further scheme: described force side is a plane away from one end of piston rod, in plane, gummed is fixed with briquetting, and described briquetting is hemispherical block rubber.
As this utility model further scheme: formed between the outer ring place of described piston head and the inner surface of syringe and seal.
Compared with prior art, the beneficial effects of the utility model are: this utility model this utility model once can be loaded and repeatedly input, and the amount of each input can control according to use needs, anesthetis is avoided to input excessive or very few, while satisfied operation needs, reduce the injury to patient, this device regulates very convenient simultaneously, user regulates the position of positioning sleeve according to required input, shortens anesthesia duration; And be threaded connection between syringe needle and needle tubing and the mount pad on syringe needle is designed to hex nut shape, both stable connections and easy accessibility, can effectively increase work efficiency, when syringe is extracted out from air-tight bottle, finger can be fastened the annular flange flange being arranged on syringe needle tube leading section, conveniently syringe needle be transferred to; The structure of this device is comparatively simple, and cost is comparatively cheap, easy to use and can increase work efficiency, and is applicable to promoting the use of.
