Abstract

The utility model relates to a transfusion alarming device. A liquid level measuring component of the utility model is a prism-shaped insulator arranged in a transfusion bottle, and a liquid level measuring point is respectively arranged in the upper, the middle and the lower three positions of three faces of the insulator. A liquid level alarming circuit is composed of two groups of liquid level detecting and alarming drive circuits, wherein the first liquid level detecting and alarming drive circuit 1 comprises two liquid level detecting circuits composed of transistors BG1, BG2, and two alarming and oscillating acoustic circuits composed of transistors BG3, BG4; the second liquid level detecting and alarming drive circuit 2 is composed of a transistor BG5 for detecting liquid level and an alarming speech circuit transistor BG6. The utility model has two stages of alarm, when transfusion liquids can be used up, the utility model can alarm in advance, when the transfusion liquids are used up and are at the top end of a transfusion pipe, the utility model can alarm once again. The utility model has the advantages of high reliability, safety and practicality and can effectively eliminate patient's pain because of artificial negligence and relieves the labor intensity of medical people and the burden of family numbers.

Description

Infusion alarm

Technical field

The utility model relates to medicine equipment, particularly a kind of alarm of the usefulness of infusing.

Background technology

China is a medical big country, and is populous, and amount of infusion is big especially.At present, in the medical venous transfusion process, need medical personnel, patient or family numbers of patients to pay close attention to the transfusion situation constantly usually.When parenteral solution is soon used up, should in time close transfusion catheter.The artificial way of transfusion state that monitors of this kind is usually failed in time to close woven hose or is changed infusion bottle because of carelessness, as because of tired, busy or do not see clearly or the like.So can cause venous backflow to go into transfusion catheter; Sometimes be totally lost for one bottle, hydraulic pressure and blood pressure balance, time liquid blood solidifies in pin and causes transfusion not proceed again, has to heavily prick a pin, brings misery to the patient; If allow air enter vein blood vessel, then will cause malpractice.

Summary of the invention

The utility model is provided with three liquid level measuring points in infusion bottle, utilize the electric conductivity and the electronic alarm circuit of liquid, so when the transfusion liquid level is in the setting alert locations, to send chimes of doom, and can effectively avoid human negligence to bring painful of patient and alleviate medical personnel's labour intensity and family members' burden.

Said infusion alarm comprises one a group of level gauging parts and a cover liquid level alarm circuit, it is characterized in that: said level gauging parts are a kind of triangular shape insulators that place in the infusion bottle, three places, three branch upper, middle and lower of insulator respectively are provided with a liquid level measuring point respectively, and vertical interval is 5～6.5mm between measuring point; Said liquid level alarm circuit is made up of two groups of Level Detection and warning driving circuit, first Level Detection and warning driving circuit 1 comprise a liquid level detection circuit that is made of triode BG1, BG2, a warning vibration sound circuit that is made of triode BG3, BG4; Second Level Detection and warning driving circuit 2 are made up of a triode BG5 and a voice alarm circuit triode BG6 who detects liquid level, the base stage of triode BG5 links to each other with the C of one of Level Detection point point, the collector of BG5 links to each other with the base stage of triode BG6, and the emitter of BG6 links to each other with the control end of speech chip HY.

The utility model has two-stage to report to the police, and when transfusion liquid is intact soon early warning is arranged, and when liquid has finished and has been in woven hose top (end that links to each other with infusion bottle), reports to the police once again.Have the reliability height, simple in structure, the characteristics of safe and applicable.Can effectively avoid human negligence to bring painful of patient and alleviate medical personnel's labour intensity and family members' burden.

Fig. 2 is the detection part structural representation.

Embodiment

Show that as Fig. 2 the level gauging parts are a kind of triangular shape insulators 3 that place in the infusion bottle, three places, three branch upper, middle and lower of insulator respectively are provided with a liquid level measuring point respectively, and A, B, C represent three measuring point present positions among Fig. 2.Vertical interval is 5～6.5mm between measuring point.Measuring point C can be provided with than the end some, 2mm is good on the woven hose top (end that links to each other with infusion bottle) to be in.Show as Fig. 1, the base stage of the triode BG1 of first Level Detection and warning driving circuit 1 links to each other with the B point of one of Level Detection point, Level Detection point A links to each other with the positive pole of power supply through K switch, the collector of triode BG1 links to each other with the base stage of triode BG2, the base stage of triode BG3 in the emitter of BG2 and the vibration sound circuit of reporting to the police links to each other, the collector of BG3 links to each other with the base stage of triode BG4, the collector of BG4 links to each other with the end of loudspeaker Y, loudspeaker Y the other end link to each other with power cathode.The base stage of the triode BG5 of second Level Detection and warning driving circuit 2 links to each other with the C point of one of Level Detection point, and the collector of BG5 links to each other with the base stage of triode BG6, and the emitter of BG6 links to each other with the control end of speech chip HY.

Below in conjunction with Fig. 1, Fig. 2 the course of work of the present utility model is described.Triangular shape insulator 3 is inserted in the infusion bottle 4, when liquid in the bottle is higher than A, B at 2, several kilo-ohms approximately of resistance between 2 of A, the B, triode BG1 saturation conduction, BG2 ends, so by BG3, BG4, resistance R 5, R7, capacitor C 2, vibration sound circuit and LED luminotron that loudspeaker Y forms are not worked.When liquid in the bottle is lower than A, B at 2, the resistance of A, B point-to-point transmission is infinitely great, be equivalent to open circuit, BG1 ends, the BG2 conducting makes by BG3, BG4, resistance R 5, R6, the vibration sound circuit that capacitor C 2, loudspeaker Y the form alerting signal of sounding, LED is luminous, and oscillation frequency is determined by R5, R6C2.When soup was in A, C section, the resistance of A, C point-to-point transmission was about several kilo-ohms equally, triode BG5 conducting, and BG6 ends, and speech chip HY does not work; When the bottle herb liquid was lower than the C point, resistance infinity between A, C point was equivalent to open circuit, and BG5 ends, the BG6 conducting, and speech chip sends the audio alert prompt tone by loudspeaker Y.
