Description

Narcotic sprayer

Technical field

The present invention relates to a kind of medical apparatus and instruments parts, relate in particular to a kind of narcotic sprayer.

Background technology

Anesthesia evaporator is a kind of device that can effectively evaporate anesthetic liquid medicine and can accurately anesthetics be inputted to breathing circuit for anesthesia by finite concentration.The degree of stability of anesthetics output concentration has determined the quality of anesthetic machine overall performance, is related to the success or failure of inhalation anesthesia, is directly involved in patient's safety.

At present domestic all vaporizers are import, aspect the mixing of medicine and air, adopt medicine evaporation more and deliver, dilute by air after enter in patient body, current vaporizer anesthetics is exported concentration maximum output 6%, precision 0.2%.

Along with the higher trend of modern body weight, existing vaporizer cannot adapt to quick, heavy dose of anaesthetic to be supplied with, and main cause is that adopted pure evaporation mode exists following limitation: one, if drug volatilization amount is larger, medicine is subject to the impact of the factors such as ambient temperature, pressure, carrier gas flow performance larger, be difficult to control the stability of output drug level, its two, if increase the disengagement area of medicine, can increase the volume of vaporising device, its cost is high, and device is heavy, not Portable belt displacement; If incorporation time is long, cannot realize quick heavy dose of anaesthetic and supply with, therefore, in working control process, be difficult to keep anaesthetic concentration to reach high-precision and stable and carry, drug level is unstable, causes administration concentration inaccuracy.

Do not increase again volume in order to increase medicine quantity delivered, this patent has adopted spray pattern to realize the supply of larger dose medicine, meanwhile, adopts corresponding narcotic sprayer, the ingenious accurate control that realizes spray amount simultaneously.

Summary of the invention

Object of the present invention, is just to overcome the shortcoming and defect of prior art, and a kind of narcotic sprayer that can accurately control drug level is provided.

In order to achieve the above object, the present invention has adopted following technical scheme: a kind of narcotic sprayer, comprises shower nozzle and printhead controller; Printhead controller and shower nozzle are movably connected can coaxial rotation; The lateral surface of printhead controller is provided with total feeding opening, is provided with passage is communicated with above-mentioned total feeding opening in the inside of printhead controller, between this passage and the medial surface of printhead controller, is provided with internal ring passage, medium ring passage and outer ring channel; Be provided with interior circular passage, middle circular passage and outer ring passage in shower nozzle inside, between interior circular passage, middle circular passage and outer ring passage and the medial surface of shower nozzle, be respectively equipped with multiple internal ring services, multiple medium ring service and multiple outer shroud service; Internal ring service, medium ring service and outer shroud service are corresponding with the position of internal ring passage, medium ring passage and outer ring channel on printhead controller respectively; Between interior circular passage, middle circular passage and outer ring passage and the lateral surface of shower nozzle, be respectively equipped with multiple internal ring spray orifices, multiple medium ring spray orifice and multiple outer shroud spray orifice.
