Embodiment Construction

[0008] Such as figure 1 As shown, a photoelectric drip alarm is composed of a laser light-emitting diode 1, a photoresistor 2, a power supply 5, a buzzer 3 and a switch 6 to form an alarm circuit. Select the corresponding parameters when there is no liquid. When there is no liquid in the infusion tube, the photosensitive resistor 2 acts to turn on the alarm power supply. When there is liquid, the photosensitive resistor 2 does not act due to poor light transmission.

[0009] The aforementioned alarm circuit is set on the support structure 4, and the support structure is two half-rings, one side is hinged, and the other side is open; on both sides. The support structure 4 is clamped on the infusion tube.

[0010] When in use, first clamp the drip alarm to the infusion tube, turn on the power switch 6 to make the laser light-emitting diode 1 emit light, adjust the photosensitive resistor 2 so that the buzzer 3 just does not sound, when the liquid level of the medicinal liquid ...

Abstract

The invention discloses a photoelectric alarm for intravenous drip, belonging to an alarm device. The alarm is characterized in that an alarm circuit comprises a laser light-emitting diode (LED), a light dependent resistor (LDR), a power supply, a buzzer and a switch, wherein the alarm circuit is arranged on a supporting structure, and the supporting structure is two semi-rings, one side of one semi-ring and one side of the other semi-ring are articulated together, and the other sides of the two semi-rings are not connected; and the laser LED and the LDR are correspondingly arranged on the supporting structure and are positioned on the two sides of a perfusion tube. The alarm is convenient in installation, and can give out an alarm when the transfusion is over, thereby avoiding doctor-patient disputes.

Description

technical field [0001] The invention relates to an alarm, in particular to a photoelectric drip alarm which can alarm when the transfusion ends. Background technique [0002] At the end of the infusion, if it is not detected in time, air will enter the patient's body, and the patient may be in danger. Need family member or medical personnel to take care of constantly when a large amount of transfusion, added unnecessary trouble. This just needs a kind of simple alarm device to send the alarm in time when the transfusion ends. Contents of the invention [0003] Aiming at the above-mentioned deficiencies, the present invention provides a photoelectric drip alarm, which is easy to install and sends an alarm in time when the infusion ends. [0004] The present invention is achieved through the following technical solutions: a photoelectric drip alarm, characterized in that: an alarm circuit is composed of a laser light-emitting diode, a photosensitive resistor, a power suppl...
