Abstract

The utility model discloses an alarm transfusion device, wich comprises a transfusion tube (1) and an observation tube (2) which are mutually connected; one side at the upper end of the observation tube (2) is provided with a light-emitting device (4); the side opposite to the light-emitting device (4) at the lower end of the observation tube (2) is provided with a photosensitive device (3); and the photosensitive device (3) is connected with a sound alarm device (6). The transfusion device can give out alarm after liquid medicine is out of use, thus avoiding the effects of blood returning and empty transfusion caused by untimely treatment after the transfusion.

Description

Alarm infusion apparatus
Technical field this utility model relates to a kind of intravenous injection device, particularly a kind of transfusion device that has alarm device.
Need to note constantly the surplus of injection in the process of background technology venous transfusion, when injection is used up, need medical personnel to handle, if carelessness, blood back, empty serious consequence such as defeated just appear in circular medical personnel easily not in time.
Utility model content technical problem to be solved in the utility model is, a kind of alarm infusion apparatus is provided, and can report to the police when injection is used up, and avoids blood back, adverse consequences such as empty defeated, overcomes the defective of prior art.
In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme:
A kind of alarm infusion apparatus comprises interconnective tube for transfusion and observing tube, it is characterized in that: one side is provided with light-emitting device in the observing tube upper end; A side relative with light-emitting device in the observing tube lower end is provided with light-sensitive unit; Described light-sensitive unit is connected with audible alarm unit.
Described light-emitting device is by power supply, and switch and light-beam transmitter serial connection form.
Described light-sensitive unit is by power supply, switch, and photoconductive resistance and audible alarm unit serial connection form.
The utlity model has following advantage: patient need not to note the medicinal liquid liquid level variation constantly when transfusion, can in time report to the police after medicinal liquid is used up, and has avoided blood back, the empty generation of failing phenomenon, has also alleviated entourage and medical worker's burden.
Description of drawings Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the circuit diagram of light-emitting device of the present utility model.
Fig. 3 is the circuit diagram of light-sensitive unit of the present utility model.
The specific embodiment as shown in Figure 1, this example comprises interconnective tube for transfusion 1 and observing tube 2, observing tube 2 left upper ends are provided with light-emitting device 4, bottom righthand side is provided with light-sensitive unit 3.
Light-emitting device 4 as shown in Figure 2, it is by power supply, switch and light-beam transmitter 5 serial connections form.
Light-sensitive unit 3 as shown in Figure 3, it is by power supply, switch, photoconductive resistance 7 and audible alarm unit 6 serial connections form.
When medicinal liquid did not drip off, storing in the observing tube 2 had the medicinal liquid of part that light beam is reflected, and can not shine in the photoconductive resistance 7, and audible alarm unit does not ring.When medicinal liquid dripped off, the light that light-beam transmitter 5 sends just in time shone in the photoconductive resistance 7, and the photoconductive resistance resistance reduces, and it is big that circuital current becomes, and audible alarm unit 6 sounds.

Claims (3)
