Abstract
An infrared infusion alarm device belongs to the technical field of medical appliances, and is characterized in that an infrared transmitting tube and an infrared receiving tube are mounted in a shell on the same side of an omega-type housing; narrow light slits used for transmitting and receiving are oppositely formed on the two sides of an infusion tube channel respectively to form a photoelectric sensor structure with relatively fixed position and light vertical to the infusion tube. The device has the beneficial effects that under the premise of no touch contamination and effective reduction of false alarm rates, the liquid level in an infusion tube is detected and alarmed conveniently, and the miniaturization can be achieved easily.
Description
Technical field
This utility model belongs to technical field of medical instruments.
Background technology
At present, to patient's infusion treatment, known infusion alarm has plenty of directly to contact by needle electrode and fluid to be measured realizes Level Detection.Existing non-contact type optics infusion alarm then is to utilize transfusion liquid in pipe and air to the different refractivity of light, makes photoelectric receiving tube produce the Photoelectric Detection that different photosignals is realized liquid level.But, adopt the direct contact liq of needle electrode, not only can't avoid the charged electrochemical reaction that causes of liquid, and easily liquid be polluted.And in the existing non-contact type optics infusion alarm, the volume that needs along the optical texture of tube for transfusion oblique fire formula is bigger, is unfavorable for using on tiny, portable tube for transfusion.Though the optical texture along tube for transfusion cross section flat fire formula is volume required less, at the type variable optical texture of clamp both sides, the rate of false alarm that the random error of both sides relative motion causes during because of use is higher, can't practical application respectively for transmitting tube and receiving tube.
Summary of the invention
The purpose of this utility model is: a kind of infrared infusion alarm is provided, and it can be accurately, reliably the transfusion situation is carried out alarm.
The technical solution of the utility model is: in shell, photoelectric sensor is connected with sound light alarming circuit.
Infrared light transmitting tube and infrared light receiving tube are installed in the same side housing of Ω formula shell, and the narrow light slit that transmits and receives usefulness is relative in the both sides of transfusion tube seat respectively, form that relative position is fixed, light and the vertical photosensor structure of tube for transfusion.
The beneficial effects of the utility model are: under the prerequisite of contactless contact scar and effective reduction rate of false alarm, easily the liquid level in the tube for transfusion is carried out detection alarm, be convenient to realize miniaturization.
Description of drawings
Fig. 1 is this utility model structure principle chart;
Fig. 2 is this utility model structure chart;
Fig. 3 is this utility model circuit diagram.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further:
As shown in Figure 1, 2, the 1st, the infrared light transmitting tube, the 2nd, the infrared light receiving tube, the 3rd, signal amplifies warning circuit, the 4th, light emitting diode, the 5th, speaker, the 6th, clothes peg formula cabinet, the 7th, button cell, the 8th, spring shaft, the 9th, tube for transfusion, the 10th, transfusion tube seat, the 11st, light slit.
As shown in Figure 3, E is that battery, K are that switch, R are that resistance, D are that infrared light transmitting tube, Q1 are that infrared light receiving tube, Q2 are that audion, Q3 are that music integrated circuit, Y are that speaker, LED are light emitting diodes.
Fig. 1 mid-infrared light transmitting tube (1) and infrared light receiving tube (2) are staggered relatively in tube for transfusion (9) both sides respectively, relative with narrow light slit. under no medicinal liquid state, infrared receiving tube can be accepted infrared light, produce photo-signal. having under the medicinal liquid state, infrared receiving tube can not be accepted infrared light, and no photo-signal produces. and the dotted arrow among Fig. 1 is the infrared beam trend when medicinal liquid is arranged.
In the embodiment shown in Figure 2, infrared light transmitting tube (1) and infrared light receiving tube (2) are installed in the same side shell of clothes peg formula cabinet (6), and narrow light slit is relative in the both sides of tube for transfusion (9).Signal amplifies warning circuit (3), light emitting diode (4) and speaker (5) and also is installed in this side shell.Button cell (7) is installed in the opposite side shell.Two parts of clothes peg formula cabinet (6) are connect by spring shaft (8), and can rotate around it, form chucking power.
