Abstract
The utility model discloses a large-area quick anesthetic needle. The large-area quick anesthetic needle comprises a needle tube, a piston is arranged inside the needle tube, a piston rod is arranged on an end portion of the piston, an end portion of the needle tube is provided with a liquid separation seat which is communicated with a cavity of the needle tube, a plurality of infusion tubes which are communicated with the cavity of the needle tube are arranged on the liquid separation seat, end portions of the infusion tubes are all provided with needle heads, and limiting stoppers are movably arranged on the needle heads respectively. The large-area quick anesthetic needle is simple in structure and reasonable in design, enables medical staff to control the puncturing depth easily, can realize multi-position anesthetization, can realize one-time medicine-feeding anesthetization, and therefore the anesthetization effect is improved, and the burden of the medical staff is eased.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of large tracts of land fast anestetic needle.
Background technology
At present, the anesthetic needle that uses clinically is disposable syringe, mainly needle body and needle handle, consists of, this anesthetic needle when to patient, anaesthetizing, is difficult to control the depth of puncture, especially for new hand, needle body in use easily rocks, and to patient, has increased misery.In addition, because the anaesthetic diffusion is slower, the inserting needle that need to repeatedly puncture when to patient, anaesthetizing like this could meet anaesthetic and spread rapidly, to increase anaesthetic area, operation very bothers like this, has increased medical personnel's burden, and due to the anesthesia bad grasp in position, do not reach the anaesthetic effect that needs, easily the impact operation normally carries out.
Summary of the invention
It is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, and easily grasps and thrust the degree of depth, can realize many places anesthesia, can anaesthetize by once daily, improves the large tracts of land fast anestetic needle of anaesthetic effect.
In order to reach above purpose, the technical scheme that this utility model adopts is: the large tracts of land fast anestetic needle, comprise needle tubing, be provided with piston in described needle tubing, the end of described piston is provided with piston rod, and the end of described needle tubing is provided with the separatory seat that is communicated with described syringe intracavity, and described separatory seat is provided with the many tube for transfusions that are communicated with syringe intracavity, the end of described tube for transfusion is equipped with syringe needle, is movably equipped with respectively stop on described syringe needle.
This utility model is also implemented by following measure: described syringe needle is provided with a plurality of liquid outlets.
Described stop is provided with for fixing holding screw.
The beneficial effects of the utility model are: simple in structure, reasonable in design, and easily grasp and thrust the degree of depth, can realize many places anesthesia, can anaesthetize by once daily, thereby improve anaesthetic effect, alleviated medical personnel's burden.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1, needle tubing; 2, piston; 3, piston rod; 4, separatory seat; 5, tube for transfusion; 6, syringe needle; 7, stop; 8, liquid outlet; 9, holding screw.
The specific embodiment
As shown in Figure 1, the large tracts of land fast anestetic needle, comprise needle tubing 1, be provided with piston 2 in described needle tubing 1, the end of described piston 2 is provided with piston rod 3, and the end of described needle tubing 1 is provided with the separatory seat 4 that is communicated with described needle tubing 1 inner chamber, and described separatory seat 4 is provided with the many tube for transfusions 5 that are communicated with needle tubing 1 inner chamber, the end of described tube for transfusion 5 is equipped with syringe needle 6, is movably equipped with respectively stop 7 on described syringe needle 6.
Described syringe needle 6 is provided with a plurality of liquid outlets 8.Can make anesthetics dispersed by a plurality of liquid outlets 8, improve anaesthetic effect.
Described stop 7 is provided with for fixing holding screw 9.Be convenient to fixedly stop 7 by holding screw 9, thereby guarantee the degree of depth that syringe needle 6 enters skin.
When to patient, anaesthetizing, due to the tube for transfusion 5 that certain-length is arranged, syringe needle 6 can be thrust under the skin of different parts so as required, can realize large tracts of land anesthesia, then pushing piston bar 3 can enter syringe needle 6 by tube for transfusion 5 with anaesthetic, and by liquid outlet 8, injects under skin.Can regulate as required its position on syringe needle 6 by stop 7, thereby determine the degree of depth of thrusting, can guarantee like this that medical personnel grasp to thrust the degree of depth, thereby reach required anaesthetic effect, can guarantee carrying out smoothly of operation.
This utility model is simple in structure, and is reasonable in design, easily grasps and thrusts the degree of depth, can realize many places anesthesia, can anaesthetize by once daily, thereby improves anaesthetic effect, alleviated medical personnel's burden.
