Abstract
The utility model discloses a transfusion sound warning instrument, and relates to the medical appliance. The transfusion sound warning instrument is provided with an openable and closable light-tight casing. The two parallel side walls of the casing are provided with semi-circle orifices. When the casing is closed, the semi-circle orifices become a round orifice, and the tube for transfusion passes through the inner chamber of the casing from the round orifice. The inner chamber is provided with a luminous tube, a photoresistor and a buzzer. The transfusion sound warning instrument can automatically sound when the liquid is nearly exhausted. The transfusion sound warning instrument advantages of small volume, light weight, simple operation, easy use, low cost and strong usability.
Description
Affiliated field
This utility model belongs to medical instruments field, specifically patient infusion automatically the sounding reminding medical personnel change dressings or pull out a kind of device of pin.
Background technology
Patient infusion is to lean on manually supervision to change dressings or pull out pin at present, because medical personnel are busy with one's work, transfusion patient or accompany personnel fail again in time to remind, delay is changed dressings or is pulled out pin, the blood back phenomenon occurring happens occasionally, in order to improve nursing quality, alleviate the artificial burden that monitors of transfusion, the alarm set that designs a kind of automatic sounding is necessary.
Summary of the invention
In order to solve the artificial deficiency that monitors of transfusion, this utility model provides a kind of convenient and practical and as safe as a house reliable sounding reminding device.
The technical solution adopted in the utility model is: a kind of transfusion news are rung reminiscences, but be provided with the light tight shell of folding, there is semicircle orifice the two parallel side wall opening and closing places that it is characterized in that housing (1), be circular hole when closed, tube for transfusion (2) passes through the housing inner chamber from the two side circular hole, at the close tube for transfusion (2) of inner chamber, fixing luminous tube (3), light emission direction is with tube for transfusion (2) skewed crossing, in fixedly photoconductive resistance of side (4) and (5) in addition near tube for transfusion (2), photoconductive resistance (4) is fixed on the straightline propagation direction of light, and photoconductive resistance (5) is fixed on the refraction direction of propagation of light.
This utility model power consumption is very little, and available minicell power supply has advantages such as volume is little, in light weight, simple to operate, easy to use, cost is low, practical.
Description of drawings
This utility model is described in detail by embodiment below in conjunction with accompanying drawing.

The specific embodiment
Shown in Figure 1, two balance side-walls of housing (1) have semicircle orifice, be circular hole when closed, tube for transfusion (2) passes through the housing inner chamber from the circular hole of two side, near the fixing luminous tube (3) of tube for transfusion (2), light emission direction is with tube for transfusion (2) skewed crossing at inner chamber, again near other sorrowful fixedly photoconductive resistance (4) and (5) of tube for transfusion (2), photoconductive resistance (4) is on the straightline propagation direction of light, and photoconductive resistance (5) is fixed on the refraction direction of propagation of light.

6Connect the base stage of audion BG, grounded emitter, colelctor electrode connects positive source by miniature news Chinese percussion instrument, the negative pole tandem tap K ground connection of power supply E.
When this utility model uses, earlier tube for transfusion is placed housing two parallel side wall semicircle orifices, closure shell then, tube for transfusion is passed through by the housing inner chamber, connect K switch, luminous tube is luminous, because light emission direction and tube for transfusion are skewed crossing, light is refracted the generation sidesway, is fixed on other side and reflects the locational photoconductive resistance 4 (R in the accompanying drawing 2
2) be illuminated, resistance decreasing is fixed on the photoconductive resistance (R in the accompanying drawing 2 on the linear propagation of light direction
2) can not be illuminated and be high resistant, two photoconductive resistance series connection mid-point voltages descend, and make the Schmidt trigger input be electronegative potential and export electronegative potential, diode D conducting, audio frequency multivibrator failure of oscillation, sounding not after news are rung; When not having liquid in the tube for transfusion, the light of luminous tube can not be refracted, and situation is with above-mentioned opposite, and the Schmidt trigger input is high potential and exports high potential, and D ends, the audio oscillator starting oscillation, and the news Chinese percussion instrument sends the prompting sound.
