Description
Technical field
The present invention relates to the automated watch-keeping facility of medical infusion bottle, the automated watch-keeping facility of a kind of medical infusion bottle venous transfusion liquid level.
Background technology
In recent years, the development of medical industry, make computer network management become an important symbol of modern hospital.Especially at medical monitoring arts, it is proposed that diversification, informationization, personalized medical monitoring demand.The progress of modern science and technology and development, provide innovation condition and new development space for medical monitoring technique, but the development of medical monitoring arts and equipment still can not meet hospital, patient, family and health of human body each side proposed requirement.Therefore networking remote medical monitor device has had the urgent market demand and wide market prospect.
In automatic medical monitor system, signal extraction is the primary premise of medical monitoring system work.Medical treatment liquid level automatic signal detection and transmission are also the processes of signal extraction, medical personnel located usually needs detection and the reserves controlling liquid or liquid level, such as the water level in decocting medicine pot in the bathing machine that the liquid measure of flushing liquor, the traditional Chinese medical science in dialysis solution reserves, automatic gastrolavage machine in the dialysis solution fluid reservoir of artificial kidney machine use, venous transfusion Level Detection etc..If liquid reserves in instrument to be negligent of monitoring, under liquid reserves out-of-control condition or bringing to patient, injure its life of even crisis.By the monitoring to these liquid reserves, medical personnel just can understand liquid residue at any time, and can when liquid lacks timely automated and artificial supplementation or take other measures, safeguard the safe operation of armarium.Therefore, being the most preferably monitored medical treatment liquid level, always medical engineering persons considers one of more problem.
At present, domestic and foreign hospitals is in transfusion bottle venous transfusion mode, infusion liquid level be there is no any type of automated watch-keeping facility, after i.e. transfusion terminates, fully rely on the timely observation of patient or caregiver, carry out stopping infusion, the most both have impact on the rest of patient, too increase the work load of caregiver.If observed not in time, it is also possible to admit air into blood vessel and produce thromboembolism.
When utilizing ultrasound wave to carry out level gauging, mainly use pulse echo method.I.e. sending ultrasonic pulse when emission sensor, air-borne transmission, when passing to liquid level, ultrasound wave is reflected, receive sensor and receive echo, cause piezoelectric chip to vibrate, produce the signal of telecommunication, the signal of telecommunication is amplified, enter single-chip microcomputer after detection, by single-chip microcomputer measuring and calculating from being transmitted into time t used by reception ultrasound wave, according to its spread speed v, distance S between sensor to liquid level just can be obtained, setting height(from bottom) H further according to sensor, so that it may draw liquid level L.As shown in Figure 1, liquid level L=H-S.
Summary of the invention
The present invention is to solve the technical problem being previously mentioned in background technology, it is provided that a kind of can automatically monitor the medical infusion bottle venous transfusion liquid level automated watch-keeping facility of level condition during transfusion bottle venous transfusion, the present invention by the following technical solutions:
A kind of automated watch-keeping facility of medical infusion bottle venous transfusion liquid level, it is characterized in that: this device includes that a transmitting terminal is positioned at above Mo Feisi dropper side, with siren ultrasonic transmitter on same straight line, it is externally provided with corresponding acoustic receiver plate at Mo Feisi dropper another side tube wall, being siren below acoustic receiver plate, described acoustic receiver plate outfan is sequentially connected with signal deteching circuit, data processor and display screen.
The automated watch-keeping facility of described a kind of medical infusion bottle venous transfusion liquid level, it is characterised in that: the size of described acoustic receiver plate needs all to receive the ultrasound wave whole sound waves after liquid level reflects.
The automated watch-keeping facility of described a kind of medical infusion bottle venous transfusion liquid level, it is characterized in that: described siren is positioned at ultrasonic transmitter straight line and launches direction, this straight line and Mo Feisi dropper intersect in siren side and are in above dropper bottommost, distance G=1CM in Fig. 2.
The having the beneficial effect that of automated watch-keeping facility of a kind of medical infusion bottle venous transfusion liquid level provided by the present invention is launched ultrasound wave by ultrasonic transmitter, then after in ink Fes dropper, liquid level drops to a certain degree, sound wave then can produce reflection and refraction at liquid level, signal can be received by acoustic receiver plate, judge current level by data processor and show, can integrated management, when siren receives sound wave and alarm.
The feature of the present invention:
1. innovative thinking is new, and the present invention utilizes ultrasound wave and computer disposal effectively to combine, and utilizes ultrasound data dexterously；
2. stability is high, convenient unified management；
3. it is convenient to install, simple to operate, easy popularization and application.

Detailed description of the invention
The operation principle of institute of the present invention foundation:
(1), when utilizing ultrasound wave to carry out level gauging, pulse echo method is mainly used.I.e. sending ultrasonic pulse when emission sensor, air-borne transmission, when passing to liquid level, ultrasound wave is reflected, receive sensor and receive echo, cause piezoelectric chip to vibrate, produce the signal of telecommunication, the signal of telecommunication is amplified, enter single-chip microcomputer after detection, by single-chip microcomputer measuring and calculating from being transmitted into time t used by reception ultrasound wave, according to its spread speed v, distance S between sensor to liquid level just can be obtained, setting height(from bottom) H further according to sensor, so that it may draw liquid level L.As shown in Figure 1, liquid level L=H-S.
(2) when the liquid level in the sound wave launched at an angle directive Mo Feisi dropper, i.e. ultrasonic transmitter and Mo Feisi dropper tube wall acutangulates angle, then sound wave can occur to launch and refraction, at this moment the acoustic receiver plate of Mo Feisi dropper another side tube wall, then can receive coherent signal thus obtain accordingly result by testing circuit and data processor.
Based on the above-mentioned operation principle be given, the invention provides the automated watch-keeping facility of a kind of medical infusion bottle venous transfusion liquid level, it is positioned at above Mo Feisi dropper side including a transmitting terminal, with siren ultrasonic transmitter on same straight line, it is externally provided with corresponding acoustic receiver plate at Mo Feisi dropper another side tube wall, being siren below acoustic receiver plate, acoustic receiver plate outfan is sequentially connected with signal deteching circuit, data processor and display screen.
