Abstract
The utility model relates to a medical appliance and particularly relates to a fast local anesthetic syringe. The fast local anesthetic syringe is provided with an injection needle head and is characterized in that an injection flow distribution plate is arranged at a pinpoint of the injection needle head, liquid outlet holes are formed at the front end parts of the injection flow distribution plate and a needle bar, one end of an operation handle is connected with the back end of the needle bar, a transparent medicine storage cavity is arranged at the other end of the operation handle, a medicine injection port and a gas injection pipe are respectively arranged on the medicine storage cavity, the medicine injection port is sealed by a medical rubber plug, and a gas flow rate control valve is arranged on the gas injection pipe. According to the fast local anesthetic syringe disclosed by the utility model, the flow distribution plate is arranged at the pinpoint, the flow distribution plate is used for sealing an original needle hole, and the flow distribution plate and the needle bar are provided with a plurality of liquid outlet small holes, so that when puncture is performed, the injuries to blood vessels and nerves of a patient can be reduced; an anesthetic solution can be uniformly sprayed out like mist because of high-pressure gas injected by the gas injection pipe; multiple positions in up, down, left and right directions can be simultaneously anaesthetized by one-time injection; the fast local anesthetic syringe has the advantages of convenience in operation, safety in use, small injuries to the patient, good anesthetic effect and the like.
Description
Technical field
This utility model relates to medical apparatus, particularly a kind of easy to operate, local quick-anaesthesia syringe of using safety.
Background technology
As everyone knows, before operation, all need be anaesthetized, oral cavity particularly, during the local operations such as beauty treatment, to carry out local anesthesia to the tooth root in oral cavity, the common syringe of the general employing of present anesthesia, syringe needle is thrust to the anesthesia position, promote the injection handle, anesthetics is injected, the minor operation of a part, often need repeatedly to puncture for several times soft tissue, so that anaesthetic is expelled to the operative site zone equably, the less than one of this method is that the pressure in injection handle and needle tubing is little, syringe needle only has an injection orifice, and the aperture of injection orifice is larger, the anesthetics injected is flow-like, make the skewness of anesthetics at operative site, the anaesthetic diffusion is slow, the effect of anesthetics is poor, dosage is large, not only cause the waste of anesthetics, the time of the awake anaesthetic of patient is long, anesthetics also works the mischief to patient's health, in addition, puncture repeatedly to patient's blood vessel, nerve causes damage, anaesthetist's operation easier and labor intensity have also been increased simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of easy to operate, use safety, the patient damaged to little local quick-anaesthesia syringe.
This utility model can reach by following measure:
A kind of local quick-anaesthesia syringe, be provided with injection needle, the needle point place that it is characterized in that injection needle is provided with the injection flow distribution plate, injection flow distribution plate and shank leading section are provided with liquid outlet, operating grip one end is connected with the rear end of shank, and the other end is provided with transparent drug storage chamber, is respectively equipped with medicine-pouring port and air injection pipe on drug storage chamber, medicine-pouring port is sealed by medical rubber stopper, and air injection pipe is provided with gas flow control valve.
This utility model is provided with flow distribution plate on needle point, flow distribution plate is by original pin hole sealing and be provided with a plurality of fluid apertures together with shank, while making to puncture, can reduce patient's blood vessel and neural damage, the gas that air injection pipe is injected high pressure makes anesthesia liquid with vaporific even ejection, a shot can be simultaneously to upper and lower, left and right is multi-faceted is anaesthetized, have easy to operate, use safety, the patient damaged to the advantages such as little, that anaesthetic effect is good.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, a kind of local quick-anaesthesia syringe, be provided with injection needle, the needle point place that it is characterized in that injection needle is provided with injection flow distribution plate 2, injection flow distribution plate 2 and shank 1 leading section are provided with liquid outlet, operating grip 3 one ends are connected with the rear end of shank 2, the other end is provided with transparent drug storage chamber 4, be respectively equipped with medicine-pouring port and air injection pipe 6 on drug storage chamber 4, medicine-pouring port is by medical rubber stopper 5 sealings, air injection pipe 6 is provided with gas flow control valve 7, this utility model is provided with flow distribution plate on needle point, flow distribution plate is by original pin hole sealing and be provided with a plurality of fluid apertures together with shank, while making to puncture, can reduce patient's blood vessel and neural damage, the gas that air injection pipe is injected high pressure makes anesthesia liquid with vaporific even ejection, a shot can be simultaneously to up and down, left and right is multi-faceted is anaesthetized, have easy to operate, use safety, the patient is damaged little, the advantages such as anaesthetic effect is good.
