Abstract
The utility model provides a level monitor for infusion, which relates to a medical device, composed of regulated power, a light emitting source, a light receptor, an amplifying circuit, a relay and an alarm, wherein, the light emitting source and the light receptor are respectively connected with the output terminals of the regulated power; light intensity signals of the light emitting source, which are detected by the light receptor, are converted into electric signals which are magnified through the amplifying circuit to drive the attraction of the delay and the alarm. When the utility model is used, the light emitting source and the light receptor are symmetrically arranged on both sides of an infusion bottle; when the liquid level of the infusion bottle drops to the level that the luminous beam of the light emitting source directly projects onto the light receptor, the alarm alarms. The utility model has the advantages of simple structure and safety. The utility model is convenient for medical nursing personnel.
Description
This utility model relates to a kind of medical transfusion monitoring arrangement.
Liquid level in the medical transfusion bottle monitors by the nursing staff at present, so nursing is very inconvenient, also easily causes malpractice.
In view of above-mentioned, the purpose of this utility model provides a kind of convenient nursing, safe and reliable transfusion liquid level monitor, when liquid level drops to desired location, can in time send signal.
The transfusion liquid level monitor that this utility model provides is made up of regulated power supply, luminous source, light-receiving device, amplifying circuit, relay and alarm.Monitor luminous source and light-receiving device that liquid level changes, symmetry is positioned at the infusion bottle both sides, when the liquid level in the infusion bottle drops to luminous source light beam direct projection light-receiving device, converts detected light intensity signal to the signal of telecommunication by light-receiving device, and, drive alarm equipment alarm through the adhesive of amplifying circuit amplification rear drive relay.
Description of drawings:
Fig. 1 is the circuit diagram of transfusion liquid level monitor;
Fig. 2 is the drip stand sketch map that transfusion liquid level monitor is housed.
With reference to Fig. 1, by transformator T, rectifier bridge D1, D2, filter capacitor C1, C2 and three terminal regulator 7812,7805 circuit of forming obtain the regulated power supply of 12 volts and 5 volts respectively, and wherein 5 volts of power supplys are exported sending and receiving light source A, usually, luminous source adopts the infraluminescence source, and 12 volts of outputs meet light-receiving device B, convert detected light intensity signal to the signal of telecommunication by light-receiving device, through audion BG1, the amplifying circuit of BG2 goes to drive the relay J adhesive after amplifying, thereby makes alarm send alarm signal again.Generally connect two alarms, wherein one is installed in the nursing working chamber, and one is installed on the drip stand.H1 among the figure, H2 all represent buzzer.
This liquid level monitor is installed on the drip stand, and as shown in Figure 2, luminous source A and light-receiving device B symmetry are positioned at the infusion bottle both sides, and C is a liquid level monitor shell.During use, utilize the irradiation position of luminous source and light-receiving device to control required liquid level, when the liquid level in the infusion bottle drops to the setting alert locations, the light beam direct projection that luminous source sends is to light-receiving device, light intensity on the light-receiving device is undergone mutation, cause the resistance of light-receiving device to reduce and make BG1, so the BG2 conducting is the normally opened contact J of relay J
-1, J
-2Adhesive, buzzer H1, H2 reports to the police, and bed item display lamp LED is bright simultaneously, so that the nursing staff in time nurses.
Transfusion liquid level monitor configuration is simple, safe and reliable, can monitor at any time to bring great convenience level condition to the nursing staff.
Claims (2)
1, a kind of transfusion liquid level monitor, it is characterized in that forming by regulated power supply, luminous source, light-receiving device, amplifying circuit, relay and alarm, luminous source, light-receiving device connect the outfan of regulated power supply respectively, convert detected luminous source light intensity signal to signal of telecommunication input amplifying circuit by light-receiving device, the output of amplifying circuit links to each other with the relay that is connected to alarm.
