Integrated medical float type oxygen inhalator for atomization/humidification conversion valve

Abstract

The invention belongs to the field of the medical instrument, in particular to an integrated medical float type oxygen inhalator for an atomization / humidification conversion valve. The integrated medical float type oxygen inhalator for the atomization / humidification conversion valve consists of an oxygen inhalator valve body (1), a humidification bottle (3) and a humidification tube (4), wherein the oxygen inhalator valve body (1) is directly provided with an atomization / humidification working mode conversion valve (6); the conversion valve (6) consists of a valve bush (607), a movable valve core (606) and a conversion valve hand wheel (602); the conversion valve hand wheel (602) is fixedly connected with the movable valve core (606) via a fastening screw (604); a groove-shaped hole (608) in the valve bush (607) and a groove-shaped through hole (8) are fixedly communicated with an oxygen inlet (10) and an oxygen outlet (12) in the oxygen inhalator valve body (1) as well as the inner cavity (25) of the oxygen inhalator valve body (1); the movable valve core (606) and the valve bush (607) are movably communicated; a flow regulation valve (2) is arranged above the side of the conversion valve (6); the humidification bottle (3) and the humidification tube (4) have the advantages of peculiar structure, convenience in operation and high safety and reliability.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a medical buoy type oxygen inhaler with an atomization / humidification conversion valve integrated. Background technique [0002] With the development of clinical treatment technology, aerosolized drug delivery in non-injection drug delivery methods has been paid more and more attention. After a long period of ultrasonic atomization, atomized drug delivery is now entering the stage of gas compression atomization. Medical nebulizers are widely used in clinical treatment as the main medical device for gas compression atomization. As the gas power source of medical nebulizers, the air compressor pump still has the obvious disadvantages of large volume, heavy weight and easy damage despite the application of various technologies. In addition, the compressor pump is noisy and expensive. Its large-scale application in hospitals is limited. The clinical treatment needs of atomized drug d...

Problems solved by technology

[0008] The purpose of the present invention: one is that the existing medical oxygen inhaler cannot directly provide the pressure oxygen power source for the drug atomizer to carry out drug atomization, or the oxygen inhaler for integrated atomization realizes the conversion of atomization and humidification working modes The structural design is complicated, the manufacturing cost is high, and the quality is not stable enough. The second is that the humidification bottle connected to the valve body of the medical oxygen inhaler cannot ensure the aseptic operation of the oxygen humidification process due to structural design restrictions, and is easily contaminated, Disinfection is inconvenient and costly, which will cause technical problems of iatrogenic nosocomial cross-infection; third, in view of the technical difficulties of existing reusable humidification tubes for repeated use and disinfection, and potential safety hazards due to poor sealing, it aims to use a It forms an integrated structure with the valve body of the oxygen inhaler, and can convert the atomization / humidification working mode into a conversion valve, and forms an atomization / humidification conversion valve together with a humidification bottle and a humidification tube. An integrated medical buoy type oxygen inhaler , the integrated medical buoy type oxygen inhaler with atomization / humidification working mode, novel in structure, convenient to operate, safe and effective, cost-effective, in line with hospital disinfection norms, low noise of humidified air flow, can ensure oxygen The whole aseptic operation of the humidification process can also provide an oxygen power source with adjustable flow rate for medical nebulizers
