Abstract

The utility model relates to a detecting and metering device for the flow quantity of the oxygen transfusion of medical use. A sensor which is composed of a set or a plurality of sets of infrared transmitters and receivers is fixed to the outside of a flow meter of buoy-typed oxygen inhalator; thus, the size of the oxygen transfusion quantity and the oxygen supply time can be monitored, and a patient can obtain the oxygen transfusion time from a display after the size of the oxygen transfusion quantity and the oxygen supply time are processed by a monolithic computer or a microprocessor; thereby, the accurate charging of the oxygen consumption can be provided with the reference. The utility model is not affected by the environment temperature and the gas pressure when the utility model is used, and a clogging phenomenon is not generated because the utility model does not take part in the gas passage directly. The utility model has the advantages of high safety, simple fabrication, low cost, high reliability and exact time keeping; thus, the utility model is welcomed by doctors and patients.

Description

The gas flow monitoring device

The utility model relates to the detection of gas flow, particularly the detection of medical oxygen therapy gas flow, measuring apparatus.

Along with the increase of modern medical service system reform and consumer's legal consciousness, the health care charge will obtain consumers in general's attention day by day, and develop to the direction of charge in accordance with the law, reasonable fee, clear charge.Chargeing as hospital's oxygen therapy has been to collect by the oxygen therapy timing, promptly consults metering with beginning and end both sides, and the difference of doctor and patient takes place to cause because of both sides' timing difference, no effective timing appliance easily.And the gas flow on the oxygen supply device detects, and generally adopts hot coupling sensor, mechanical gear table, all kinds of gas flow sensor.Though these sensor precision height, it is very big influenced by gaseous species, environment temperature, gaseous tension, and response speed is slow simultaneously, the volume power consumption is bigger, is not suitable for the on-the-spot use of hospital ward.Also might influence patient health in addition because the intervention of sensor produces pollution formation hospital infection, and price is rather stiff.The plugging fault that such sensor has will threaten patient's life.

The purpose of this utility model provides a kind of gas flow monitoring device in order to overcome above-mentioned weak point of the prior art just, can gas flow be detected, measure, and is practical, easy, reliable.

The design forms sensor by infrared and receiving trap, be placed on the retainer plate, be enclosed within the bottom of the flowmeter of float type oxygen inhalation apparatus again, sensor can be the 1-15 group, can be evenly distributed, also can 1-15 to arranging in groups, can be respectively detect to the size of oxygen therapy amount with the oxygen time; The circuit of display is that the electric signal that sends of the sensor that will be in different oxygen therapy amount sizes is after amplifier amplifies, by single-chip microcomputer or microprocessor after IC-card sends the reseting cipher signal, single-chip microcomputer or microprocessor can be respectively or are sent timing signal and send signal to outside communication network for simultaneously LED or LCD, and external network also can send command signal to single-chip microcomputer or microprocessor; Single-chip microcomputer or microprocessor can also be to the IC-card storage datas; Electric energy is provided for single-chip microcomputer or microprocessor, sensor, display by uninterrupted power source.

The design compared with prior art has following advantage: be not subjected to the influence of environment temperature, gaseous tension, owing to do not participate in the gas passage directly, thereby do not produce obstruction, safe; Make simple, with low cost, reliability is high, accurate timing.The design also can be used for the detection and the metering of other gas flow.

Below be the drawing explanation of the utility model accompanying drawing:

The utility model is described in further detail below with reference to embodiment:

Embodiment. a kind of gas flow monitoring device, referring to Figure of description 1-6, the design forms sensor by infrared (1) and reception (2) device, be placed on the retainer plate (3), be enclosed within the bottom of the flowmeter (4) of float type oxygen inhalation apparatus again, sensor can be the 1-15 group, can be evenly distributed, also can 1-15 to arranging in groups, can be respectively detect to the size of oxygen therapy amount with the oxygen time; The circuit of display (5) is that the electric signal that sends of the sensor that will be in different oxygen therapy amount sizes is after amplifier amplifies, by single-chip microcomputer or microprocessor after IC-card sends the reseting cipher signal, single-chip microcomputer or microprocessor can be respectively or are sent timing signal and send signal to outside communication network for simultaneously LED or LCD, and command signal can be sent to single-chip microcomputer or microprocessor by external network in the hospital care center; Single-chip microcomputer or microprocessor can also be to the IC-card storage datas; Electric energy is provided for single-chip microcomputer or microprocessor, sensor, display by uninterrupted power source.

The design's principle of work is: infrared and receiving sensor are placed in the position of flowmeter shown in Fig. 2,3,4 of float type oxygen inhalation apparatus.When gas did not pass through flowmeter, the buoy in the flowmeter was to be in low spot, just in time blocks ultrared path, makes infrared receiver can not receive signal, and flow is 0, and display is not-time.When the flowmeter, the buoy in the flowmeter upwards floats and leaves low level as gas, and sensor can receive signal, gives single-chip microcomputer and microprocessor is handled, and sends signal to display and pick up counting.IC-card can make single-chip microcomputer and microprocessor reset, and allows display from newly picking up counting, and IC-card can write down the time of gas flow and gas use.

As Fig. 3, the paired arranged in groups of the design's sensor, when A group working sensor, other group is blocked, and when B group working sensor, other group is blocked, by that analogy.Can judge the size of flow like this.

The design also can be used for the detection of other gas flow and metering, timing, as the use of nitrogen, ammonia, carbon dioxide.
