Abstract
The utility model relates to an administration device used for local anaesthesia, which comprises a syringe and an injection needle. The syringe comprises an inner syringe, an outer syringe and push rods. The inner syringe extends into the outer syringe. The outer wall of the inner syringe is in tight contact with the inner wall of the outer syringe. A separator plate is arranged inside the inner syringe. The inner syringe is divided into a left cavity and a right cavity by the separator plate. The two push rods respectively extend into the left cavity and the right cavity from above. The lower ends of the push rods are provided with sealing rubber pistons. The lower ends of the left and right cavities are provided with two branch drug outlet ports communicated with the outer syringe. The lower end of the outer syringe is provided with a general drug outlet port connected with the injection needle. Compared with the prior art, due to the adoption of the administration device, the injection for two times can be completed only through one-shot puncture operation. Therefore, the soup after the injection process is high in mixing degree and the pain of a patient during the injection process is effectively relieved.
Description
Technical field
This utility model relates to a kind of doser, especially relates to a kind of doser that is used for local anesthesia.
Background technology
Local anesthesia is meant office's anesthetics is injected in a certain position of health, the technology of this position sensation of temporary interruption and nervus motorius conduction.Simple, safe, complication is few.
Lignocaine is a kind of of local anesthetic, and is rapid-action, and the length of holding time has stronger tissue penetration property and diffusibility, is the maximum local anesthetic of present clinical use.When but lignocaine was implemented local anesthesia, a lot of patients main suit had violent twinge or burning pain, possibly be acid relevant with its configuration medicinal liquid pH value.
In order to alleviate this pain, people have proposed the method for preform injection.That is: before injection site anesthetics lignocaine, the local preform injection physiological saline solution of elder generation, its 0.9% contained benzyl ethanol can effectively alleviate the injection pain of lignocaine.But the method for this preform injection need successively be carried out 2 punctures in the part, has increased patient's anxiety sense and sense of discomfort, and on the other hand, the injection point of local anesthetic is difficult to overlap with the injection point of normal saline, and the mixing of two kinds of medicinal liquids is accurate inadequately.
The utility model content
The purpose of this utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of doser that is used for local anesthesia to be provided; This doser only needs one-time puncture can accomplish double injection; Injection back medicinal liquid degree of mixing is high, can effectively alleviate pain on injection.
The purpose of this utility model can realize through following technical scheme:
A kind of doser that is used for local anesthesia comprises syringe and injection needle, it is characterized in that; Described syringe comprises interior syringe, outer syringe and push rod, and described interior syringe stretches in the outer syringe, and the outer wall of interior syringe closely contacts with the inwall of outer syringe; Be provided with a dividing plate in the syringe in described, this dividing plate is divided into left chamber and right chamber with interior syringe, and described push rod is provided with two; Stretch into left chamber and right chamber respectively from the top; The lower end of push rod is provided with the rubber piston that is used to seal, and described left chamber and right chamber lower end are provided with two branch medicine outlets, are communicated with outer syringe; Described outer syringe lower end is provided with a total medicine outlet, and described injection needle is connected on total medicine outlet.
Described push rod is the semicircle push rod that cooperates with left chamber and right chamber.
The outer surface of syringe is provided with graduation mark in described, and the cylindrical shell of outer syringe is transparent.
Described syringe adopts polyolefin thermoplastic elastomer (TPE) material.
Compared with prior art, the utlity model has following advantage:
1, easy to use: as only to need one-time puncture during this utility model injection, can two kinds of medicinal liquids successively be injected in the body, alleviate penetration damage, reduce opportunities for contamination, increase work efficiency.
2, definite effect: during injection, inject physiological saline solution earlier in the injection site, the local anesthetic that reinjects, two kinds of injecting liquid drug points are identical, and mix homogeneously can significantly alleviate the local anesthetic pain on injection.
3, dependable performance: outer syringe cylindrical shell is transparent, and interior syringe indicates graduation mark, can accurately measure liquid dose, and observation have or not bubble, graduation mark is clear, not fugitive color.
4, material safety: this utility model main body adopts polyolefin thermoplastic elastomer (TPE) material, and each item performance all is superior to traditional polrvinyl chloride (PVC) material, and has avoided some toxic and side effects (contaminated environment, carcinogenic etc.).
