Abstract
The utility model relates to a metering device for the hospital center oxygen supply or the cylinder oxygen supply, and also can be widely applied for the measuring of the micro flow of other fields. The medical oxygen flow gauge is characterized in that an air inlet with an adjustable valve is connected with a sealing air chamber; a pressure sensor is arranged in the sealing air chamber; the pressure sensor is connected with a single chip computer through an analog-to-digital (A/D) converter; the output end of the single chip computer is connected with a display; the wall of the sealing air chamber is provided with a limiting hole which is used as the output end of the oxygen. The limiting hole is provided with a plurality of hole diameters, and the size arranges of the hole diameters are between 0. 1 mm to 10 mm. The display is provided with an instantaneous flow display and a cumulative flow display. A locking ring is provided between the pressure sensor and the A/D converter. The utility model has high accuracy, small volume, convenient operation, accurate oxygen flow measuring and easy, and easy, clear and visual digital display, and cuts down the dispute caused by the inaccurate measuring between the patient and the hospital.
Description
One, technical field: the utility model relates to the measuring apparatus of a kind of HC oxygen supply or steel cylinder oxygen supply, also can be widely used in the metering of the gas trace flow in other field.
Two, background technology: at present, during the hospital patient oxygen uptake, owing to lack necessary measuring fixed amount means, expenses standard all is to charge according to the oxygen time of the doctor in charge's doctor's advice requirement, what and time of oxygen absorbed can't measure, and hospital said oxygen uptake 8 hours, and patient or family members say there are not 8 hours, so often take place between hospital and the patient about what dispute of oxygen absorbed, what of patients accepting oxygen inhalation amount also can influence patient's the state of an illness simultaneously.Up to this point, go back the complete pick-up unit of neither one and can accurately measure the oxygen absorbed of controlling patient patient's oxygen absorbed.
Three, summary of the invention:
1, goal of the invention: the utility model provides a kind of medical oxygen flowmeter measuring device, and its purpose is to solve the problem that does not also have the complete oxygen flow metering device of a cover and exist in hospital.
2, technical scheme:
Medical oxygen flowmeter measuring device, it is characterized in that: an air intake that has variable valve is connected with a sealed air chamber, in sealed air chamber, be placed with pressure transducer, pressure transducer is connected with a single-chip microcomputer by A/D converter, the output terminal of single-chip microcomputer connects a display, is provided with the output terminal of metering hole as oxygen on the blanket gas locular wall.
Metering hole is provided with a plurality of apertures, and the magnitude range in aperture is at 0.1～10mm.
Display is provided with instantaneous delivery display and integrated flow display.
3, advantage and effect: the utility model provides a kind of medical oxygen flowmeter measuring device, it is owing to adopt electromechanical integration technology, make this accuracy of instrument height, volume is little, easy and simple to handle, flow metering to oxygen is accurate, and numeral shows easy to be clear directly perceived, has reduced between patient and the hospital owing to the inaccurate dispute that causes of metering.Simultaneously, oxygen absorbed is realized control, also the state of an illness to patient provides foundation accurately, also makes hospital improve the transparency of charge, and charge also has according to following.
Four, description of drawings:
Fig. 1 is the structural representation of the utility model integral body.
Five, embodiment:
Medical oxygen flowmeter measuring device described in the utility model, be provided with the air intake 1 of oxygen in the bottom of meter, air intake 1 is provided with variable valve 2, and an end of oxygen air intake 1 is connected with the Central oxygen-supply of hospital or oxygen supply steel cylinder 12, and the other end is connected with sealed air chamber 3.Be provided with pressure transducer 5 on the top of sealed air chamber 3, be provided with retaining ring 6 between pressure transducer 5 and the A/D converter 7, pressure transducer 5 and A/D converter 7 are connected by circuit.A/D converter 6 is connected with Single Chip Microcomputer (SCM) system 8.The output terminal of Single Chip Microcomputer (SCM) system 8 is connected with a display 9.Have a very thin metering hole 4 on the sidewall of sealed air chamber 3, the magnitude range of metering hole 4 is between 0.1～10mm, and metering hole 4 communicates with the humidifying cup as the output terminal of oxygen, links to each other with patient's mouth and nose then.
