Abstract
The utility model discloses a transfusion catheter alarm with a light screen. The utility model comprises a light screen 1 and an alarm giving control circuit, wherein the light screen 1 is sheathed on a transfusion catheter 2; the alarm giving control circuit comprises a photoelectric conversion circuit, an amplifying circuit, a sound circuit, a power supply and a switch; a corresponding position is provided with small holes 3 on the light screen 1; a light emitting tube in the photoelectric conversion circuit in the alarm giving control circuit is positioned before one of the small holes; a light receiving tube is installed before the other small hole. The utility model, which has the following advantages of good reliability, small volume, low cost and use convenience, can completely stop medical accidents, such as blood regurgitation, bubble input, etc., which lightens the labor intensity of medical staff. The utility model is an ideal liquid monitoring device during a patient's transfusion.
Description
Affiliated field
This utility model relates to a kind of infusion alarm, particularly a kind of band dark slide tube for transfusion alarm.
Background technology
When hospital gave patient infusion now, because nurse and patient monitor inadequately, often liquid had been totally lost and has not also been known, caused malpracticees such as blood back, input bubble, had brought many miseries to patient.If an alarm is installed, when being totally lost, liquid reports to the police at once, and remind medical personnel in time to add liquid or close transfusion device, thereby reduced malpractice.But the alarm of development all because of poor reliability, uses operation inconvenience as pressure type, vicarious, electronic type etc. at present, and problems such as volume is big, cost height can not get applying always.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, provides a kind of easy to operate, the band dark slide tube for transfusion alarm that volume is little, cost is low, and its good reliability can alleviate medical personnel's labor intensity greatly.
The purpose of this utility model is achieved through the following technical solutions: band dark slide tube for transfusion alarm, it comprises dark slide and alarm control circuit, dark slide is enclosed within on the tube for transfusion, alarm control circuit comprises photoelectric switching circuit, amplifying circuit, pronunciation circuit, power supply and switch, relative position is provided with aperture on the dark slide, before the light-emitting tube of photoelectric switching circuit is positioned at one of them aperture in the alarm control circuit, before another aperture light receiving tube is installed.
By top narration as can be seen, the utlity model has following advantage: good reliability, volume is little, cost is low, and is easy to use, can stop malpracticees such as blood back, input bubble fully, alleviated medical personnel's labor intensity greatly, ideal liquid supervising device when being patient infusion.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described: band dark slide tube for transfusion alarm, it comprises dark slide 1 and alarm control circuit, dark slide 1 is enclosed within on the tube for transfusion 2, alarm control circuit comprises photoelectric switching circuit, amplifying circuit, pronunciation circuit, power supply and switch, relative position is provided with aperture 3 on the dark slide 1, before the light-emitting tube D1 of photoelectric switching circuit is positioned at one of them aperture in the alarm control circuit, light receiving tube D2 is installed before another aperture.
Photoelectric switching circuit comprises light-emitting tube D1, light receiving tube D2, resistance R 1, variable resistance W1, light-emitting tube D1, resistance R 1, variable resistance W1 series connection, and light-emitting tube D1 is connected by light path with light receiving tube D2; Amplifying circuit comprises audion T1, resistance R 2, and the base stage of audion T1 connects light receiving tube D2, and the colelctor electrode of audion T1 connects resistance R 2; Pronunciation circuit comprises pronunciation ic chip 1, audion T2, buzzer L1, and 1 one drive ends of the colelctor electrode of audion T1 and pronunciation ic chip are connected, and the output of pronunciation ic chip 1 connects audion T2 base stage, the emitter-base bandgap grading output alarm signal of audion T2.
Dark slide 1 has two, is fixed on the tube for transfusion with clip or adhesive tape etc.
Two dark slides 1 surround the cylindrical or polyhedron of hollow, and tube for transfusion passes from the centre.
Operation principle: the light that is sent by light-emitting tube D1 penetrates tube for transfusion arrival light receiving tube D2 by the aperture on the dark slide 13, no liquid or bubble is arranged in tube for transfusion, this moment, light intensity strengthened, by resistance R in the photoelectric switching circuit 1, variable resistance W1 effect, produce stronger electric current and send chimes of doom through amplifying circuit T1, R2 amplification signal driving pronunciation circuit IC1, T2, L1.The effect of two dark slides is for making the alarm reliably working, prevent other interference of light sources, and dark slide can be made with lighttight plastics, metal, cardboard etc., thereby reaches the purpose that reliable monitoring transfusion liquid in pipe changes.For reaching better monitoring effect, diverse location can be provided with a plurality of band dark slide tube for transfusion alarms on tube for transfusion.
