Abstract
The utility model relates to medical instruments, in particular to a quick local anesthetizing device. The quick anesthetizing device is provided with a needle and is characterized in that the front end of the needle is sealed and conical, at least four liquid outlets are formed in the front end of the needle, an operation handle is arranged at the rear end of the needle, the rear end of the needle is connected with the lower end of a medicine storage cavity through a medical liquid-guiding rubber hose, the upper end of the medicine storage cavity is connected with a high-pressure air source through a medical air-guiding rubber hose, a medicine injection port is formed in the wall of the medicine storage cavity and is sealed with a medical rubber plug, a liquid flow control valve is arranged on the medical liquid-guiding rubber hose, and an air flow control valve is arranged on the medical air-guiding rubber hose. When the device is used, narcotics are injected into the medicine storage cavity through the medical rubber plug with an injector firstly, then the air flow control valve on the medical air-guiding rubber hose is opened to enable certain pressure to exist in the medicine storage cavity so that the narcotics can be sprayed out evenly in a mist mode, and then the narcotics are in full contact with nerves inside the body of a patient to achieve quick anesthetization. The quick anesthetizing device has the advantages of being convenient to operate, safe in use, small in injury to the patient, good in anesthetizing effect and the like.
Description
Technical field
This utility model relates to medical apparatus, particularly a kind of easy to operate, use safety, reusable Quick anaesthesia device.
Background technology
As everyone knows, before operation, all need anaesthetize, 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 anesthesia position, promote injection handle, anesthetics is injected, a local minor operation, often need repeatedly to puncture for several times soft tissue, so that anaesthetic is expelled to operative site region 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 injecting is flow-like, make anesthetics at the skewness of operative site, 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, syringe needle is hollow pipe, the front end of syringe needle is an inclination tangent plane, the syringe needle blood vessel to patient that punctures repeatedly, nerve causes damage, the hollow muscle of easily filling in patient of syringe needle end, also anaesthetist's operation easier and labor intensity have 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, to patient damage little, can reusable local Quick anaesthesia device.
This utility model can reach by following measure.
A kind of local Quick anaesthesia device, be provided with injection needle, the front end sealing that it is characterized in that injection needle is tapered, leading section is provided with at least four liquid outlets, the rearward end of injection needle is provided with operating grip, the rear end of injection needle is connected with the lower end of drug storage chamber through medical drain sebific duct, the upper end of drug storage chamber is connected with high-pressure air source through medical inducing QI sebific duct, drug storage chamber wall is provided with medicine-pouring port, medicine-pouring port is sealed by medical rubber stopper, medical drain sebific duct is provided with liquid flow control valve, and medical inducing QI sebific duct is provided with gas flow control valve.
Medical drain sebific duct described in the utility model is provided with fluid flowmeter scale, and medical inducing QI sebific duct is provided with gas flowmeter scale, with handled easily.
When this utility model is used, first with syringe by anesthetics in medical rubber stopper is injected to drug storage chamber, open again the gas flow control valve on medical inducing QI sebific duct, make in drug storage chamber, to there is certain pressure, Anesthetist's hand-held handle thrusts syringe needle in patient body, by regulating the liquid flow control valve on medical drain sebific duct, anesthetic liquid medicine in drug storage chamber by the liquid outlet of syringe needle leading section with vaporific even ejection, fully contact with the nerve in patient body, reach the object of quick fiber crops acid, have easy to operate, use safety, patient is damaged little, the advantages such as anaesthetic effect is good.
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 device, be provided with injection needle 1, the structure of injection needle 1 is same as the prior art, this does not repeat, the front end sealing that is characterised in that injection needle 1 of the present utility model is tapered, leading section is provided with at least four liquid outlets, the rearward end of injection needle 1 is provided with operating grip 2, the rear end of injection needle 1 is connected with the lower end of drug storage chamber 4 through medical drain sebific duct 3, the upper end of drug storage chamber 4 is connected with high-pressure air source through medical inducing QI sebific duct 5, drug storage chamber 4 walls are provided with medicine-pouring port, medicine-pouring port is by medical rubber stopper sealing 6, medical drain sebific duct 3 is provided with liquid flow control valve 7, medical inducing QI sebific duct 6 is provided with gas flow control valve 8, in addition, medical drain sebific duct 3 described in the utility model is provided with fluid flowmeter scale 9, medical inducing QI sebific duct 6 is provided with gas flowmeter scale 10, with handled easily, during use, first with syringe by anesthetics in medical rubber stopper is injected to drug storage chamber, open again the gas flow control valve on medical inducing QI sebific duct, make in drug storage chamber, to there is certain pressure, Anesthetist's hand-held handle thrusts syringe needle in patient body, by regulating the liquid flow control valve on medical drain sebific duct, anesthetic liquid medicine in drug storage chamber by the liquid outlet of syringe needle leading section with vaporific even ejection, fully contact with the nerve in patient body, reach the object of quick fiber crops acid, the utlity model has easy to operate, use safety, patient is damaged little, the advantages such as anaesthetic effect is good.
