Timing, metering and charging device for oxygen delivery

Abstract

A timing, metering and charging device for oxygen delivery belongs to the technical field of medical equipment. The technical scheme is that the timing, metering and charging device comprises a gas pressure sensor, a temperature regulating device, a control device, a display device, a warning device and a communication device, wherein the gas pressure sensor and the temperature regulating device are arranged between an oxygen input end and an oxygen output end of oxygen delivery equipment; the gas pressure sensor transmits a pressure signal acquired and the temperature regulating device transmits an actual oxygen delivery temperature signal acquired to the control device; the control device is provided with two paths for outputting; one path outputs the oxygen delivery time, the oxygen flow and the oxygen consuming cost to the display device, and the other path outputs the oxygen flow to the warning device; the display device transmits the oxygen delivery time, the oxygen flow and the oxygen consuming cost and the warning device transmits a warning signal to the communication device. The timing, metering and charging device is used for detecting the oxygen supply amount and the oxygen supply time of the oxygen delivery equipment and calculating the oxygen delivery cost, and is convenient to use, high and accurate in data real-time performance, safe, and reliable.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an oxygen meter metering and billing device. Background technique [0002] Oxygen infusion is a common medical method. At present, doctors use humidification bottles to infuse oxygen to patients, and humidify the dry oxygen through the humidification bottles. Oxygen masks for patients to inhale through the mouth. Generally, when in use, there is no special oxygen inhalation timing and metering device, but the approximate oxygen inhalation time is manually recorded by medical personnel, and the oxygen delivery fee is calculated by multiplying the time by the unit price. This method not only cannot accurately time, but also cannot accurately measure, often It caused disputes over charges, and the manual monitoring of the oxygen delivery process also greatly increased the workload of medical staff. [0003] At present, in response to the above problems, medical personnel use...

Problems solved by technology

[0005] However, from the perspective of long-term use, this mechanical structure of synchronous opening and closing of oxygen delivery and timing, due to multiple mechanical frictions, causes wear and tear changes in each structure, which cannot be used quickly, flexibly and accurately, which may cause the timing of oxygen. The flowmeter moves slowly or malfunctions or even does not move, which reduces its service life; and the above-mentioned flowmeter is generally a float type gas flowmeter, and the measurement value is inaccurate and has a large error; in addition, medical personnel need to manually copy the The oxygen flow and oxygen consumption time data measured by the timing oxygen flowmeter are then manually converted into the oxygen consumption cost and input into the medical system to count the patient's medical expenses, and the patient cannot adjust the oxygen consumption according to the needs during use
