Description
Technical field
This utility model relates to a kind of micro-anesthetic syringe, belongs to Anesthesia Department's technical field of medical instruments.
Background technology
At present, in Anesthesia Department, often need to carry out local anesthesia for patient's different parts, therefore need to beat anesthetic needle to patient, the gauge needle of anesthesia sets operative site and time, and anesthetic needle used during anesthesia mostly is traditional syringe.But for some local operations and small-sized operation, to mend pin during the course, only need trace to anaesthetize, traditional syringe extracts unnecessary anesthetis and extremely wastes, and due to trace anesthesia, be difficult to the injection volume controlling syringe.To extract and injection is lost time all very much, therefore, extremely need a kind of when anaesthetize for trace or when mending pin to use syringe.
Summary of the invention
In order to solve above-mentioned deficiency, this utility model provides one micro-anesthetic syringe, its inside is provided with tiny cylinder and is used as medicine chamber, surface is provided with scale, unclamp after the rubber cap pressing of top, extract a small amount of anesthetis and enter intracavity, lower end is provided with the needle hub of standard configuration, access syringe needle, thumb press controls to get rid of medicinal liquid.
This utility model solves the technical scheme that its technical problem adopts: a kind of micro-anesthetic syringe, be made up of rubber cap, upper cylindrical cavity, lower cylindrical cavity and needle hub, upper cylindrical cavity, lower cylindrical cavity and needle hub are transparent plastic and make, lower cylindrical cavity surface is provided with scale, and upper cylindrical cavity is column type, is inside provided with cylindrical cavity, bottom is provided with female thread, top is spherical-concave-surface, and a rubber cap is fixed on upper cylindrical cavity top, and rubber cap is ball convex.Lower cylindrical cavity top is provided with external screw thread, and bottom is fixedly connected with a needle hub.Upper cylindrical cavity screw thread screws lower cylindrical cavity, and its inner cylindrical cavity leads to, and cylindrical cavity upper end is in rubber cap, and lower end is stretched out from needle hub.
The beneficial effects of the utility model are: solve in surgery anesthesia process for waste when trace anesthesia or benefit pin, the very difficult problem controlling injection volume and extraction and injection and lose time all very much.Easy to operate, easy for installation, convenient disassembly, easy cleaning.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Fig. 1 is front view of the present utility model.
Fig. 2 is the front view after this utility model is analysed and observe.
Number in the figure:
1, rubber cap, 2, upper cylindrical cavity, 3, lower cylindrical cavity, 4, needle hub.
Detailed description of the invention
As shown in Fig. 1-Fig. 2, a kind of micro-anesthetic syringe, be made up of rubber cap 1, upper cylindrical cavity 2, lower cylindrical cavity 3 and needle hub 4, upper cylindrical cavity 2, lower cylindrical cavity 3 and needle hub 4 are transparent plastic and make, and lower cylindrical cavity 3 surface is provided with scale, upper cylindrical cavity 2 is in column type, inside be provided with cylindrical cavity, bottom is provided with female thread, and top is spherical-concave-surface, a rubber cap 1 is fixed on upper cylindrical cavity 2 top, and rubber cap 1 is in ball convex.Lower cylindrical cavity 3 top is provided with external screw thread, and bottom is fixedly connected with cylindrical cavity 2 screw thread on a needle hub 4. and screws lower cylindrical cavity 3, and its inner cylindrical cavity leads to, and cylindrical cavity upper end is in rubber cap 1, and lower end is stretched out from needle hub 4.
Using method:
After cleaning and sterilizing, manually upper cylindrical cavity body 2 screw thread is screwed lower cylindrical cavity body 3, syringe needle is inserted in needle hub 4, needle contact anesthetis, after thumb press rubber cap 1, unclamps thumb, anesthetis is sucked in micro-anesthetic syringe cavity.Then anesthesia place is anaesthetized.Because the cavity under rubber cap 1 is limited, so inhalation anesthetic is limited.And inner chamber body small volume, total is transparent, so consumption during injection very easily controls.
