Intelligent oxygen inhaling measuring instrument

Abstract

The invention relates to an intelligent oxygen inhaling measuring instrument, belongs to medical instruments and measuring devices, which are used for calculating flow quantity, oxygen inhaling time and expense during oxygen inhaling treatment, and has the advantages that the optical radiation scanning technology is adopted to determine the location of a floater, an integrated circuit and a singlechip are adopted to calculate and read the corresponding flow quantity, the degree of accuracy is high, the accuracy and the fairness of oxygen inhaling billing can be improved greatly, doctor-patient conflicts are reduced, meanwhile, the intelligent oxygen inhaling measuring instrument is more convenient and efficient, the workload of a nurse is reduced.

Description

Technical field [0001] The invention relates to an intelligent metering instrument for oxygen inhalation, which belongs to medical instruments and metering instruments used for calculating oxygen flow rate, oxygen inhalation time, oxygen inhalation cost, etc. during oxygen inhalation therapy. Background technique [0002] Oxygen inhalation is one of the most commonly used rescue or treatment methods in hospitals. The flow meter is one of the necessary equipment and measuring instruments for adjusting and observing the oxygen flow during oxygen inhalation. At present, domestic hospitals generally use float flowmeters. The principle is to blow up the float in the tapered tube by the oxygen flow flowing through it, and visually measure the flow scale corresponding to the position of the float to calculate the flow rate. However, the defects of this type of product are large errors and inconvenient readings. , the data cannot be stored. [0003] In recent years, electronic flo...

Problems solved by technology

At present, domestic hospitals generally use float flowmeters. The principle is to blow up the float in the tapered tube by the oxygen flow flowing through it, and visually measure the flow scale corresponding to the position of the float to calculate the flow rate. However, the defects of this type of product are large errors and inconvenient readings. , the data cannot be stored

[0003] In recent years, electronic flowmeters have also been produced in China by combining various gas flow sensors and single-chip microcomputers. The price of the flow sensor is very high. The unit price of the gas flow sensor alone ranges from hundreds to thousands of yuan, which causes the overall cost of the product to be too high, so it cannot be widely used in hospitals.
