Technical field
This utility model relates to a kind of medical intravenous drip monitoring device.
Background technology
Medical some dropping liquid kind is a lot, shape varies, these dropping liquids in time send the prompting alarm when infusion process closes to an end be very necessary, people's life is of great value, do not allow carelessness, artificial monitoring waste great amount of manpower, and the people also dozes off, he when neglects, drop is beaten the needle tubing that is over and is not also extracted, and causes situations such as blood backflow easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of medical intravenous drip monitoring device.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of medical intravenous drip monitoring device, it comprises the sniffer that part is interior, can detect liquid level information that expands that places tube for transfusion, with detection to liquid level information be converted into optical signal reforming unit and be connected the testing circuit that is converted into the signal of telecommunication on the reforming unit, with optical signal.
Further, sniffer is a ball float, and ball float can float along with the interior liquid of part that expands of tube for transfusion; Reforming unit is a shade, and shade is fixedly connected on the infusion support, and be sleeved on tube for transfusion expand the part place, shade is provided with the pair of corresponding hole around expanding the two side of part, the hole on one of them sidewall is corresponding with testing circuit; When expanding the liquid level of part when being positioned at normal height, ball float covers described hole fully, and together covers all light that are mapped to testing circuit with shade, and when ball float descended with liquid level, light can arrive testing circuit by the hole on the shade two lateral walls.
Further, a sidewall of shade is uncovered shape, and this open width makes the part of expanding of tube for transfusion just embed shade, and is difficult for breaking away from shade less than the diameter partly that expands of tube for transfusion.
Further, an end of shade is provided with hook.
Further, testing circuit is connected on the shade, and testing circuit comprises photoconductive resistance and alarm, described photoconductive resistance be arranged on shade one sidewall on corresponding position, hole, described alarm is connected with photoconductive resistance.
Further, the diameter of ball float is greater than the radius that expands part of tube for transfusion, and less than expanding section diameter.
The beneficial effects of the utility model are: simple in structure, easy to use, and in time give the alarm when drop closes to an end and save the human resources, and the danger of avoiding human negligence to arrive, safe and reliable.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is the structural representation of this utility model shade;
Fig. 3 is this utility model circuit theory diagrams.
In the accompanying drawing, the list of parts of each label representative is as follows:
1, shade, 11, the hole, 12, hook, 2, ball float, 3, testing circuit, 4, expand part.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain this utility model, is not to be used to limit scope of the present utility model.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of medical intravenous drip monitoring device, it comprises and places expanding in the part 4, can detecting the sniffer of liquid level information of tube for transfusion, with detection to liquid level information be converted into optical signal reforming unit and be connected the testing circuit 3 that is converted into the signal of telecommunication on the reforming unit, with optical signal.
Sniffer is a ball float 2, and ball float 2 can float along with the part 4 interior liquid that expand of tube for transfusion; Reforming unit is a shade 1, shade 1 is fixedly connected on the infusion support, and be sleeved on tube for transfusion expand part 4 places, shade 1 is provided with pair of corresponding hole 11 around expanding the two side of part 4, the hole 11 on one of them sidewall is corresponding with testing circuit 3; When expanding the liquid level of part 4 when being positioned at normal height, ball float 2 covers described hole 11 fully, and together cover all light that are mapped to testing circuit 3 with shade 1, when ball float 2 descended with liquid level, light can arrive testing circuits 3 by the hole on shade 1 two lateral walls 11.
One sidewall of shade 1 is uncovered shape, and this open width makes the part 4 of expanding of tube for transfusion just embed shade 1 less than the diameter that expands part 4 of tube for transfusion, and is difficult for breaking away from shade 1.
One end of shade 1 is provided with hook 12, uses common rope by linking up with 12 this utility model to be fixed on the infusion support.
The diameter of ball float 2 is greater than the radius that expands part 4 of tube for transfusion, and less than expanding part 4 diameters.
Also this utility model directly can be fixed on the infusion support by modes such as welding
This utility model in use, tube for transfusion expands medicinal liquid height in the part 4 at least greater than the radius of ball float 2. make ball float 2 that the space of decline be arranged.For testing circuit 3 adds voltage about 5v, when ball float 2 covers the light time fully, the resistance of photoconductive resistance can not change, and does not have electric current to pass through capacitor C, so alarm is not worked.When medicinal liquid output, tube for transfusion expands the ball float 2 of part 4 the insides and just descends gradually along with the output of medicinal liquid, drop to the below of hole 11 horizontal planes when ball float, make ball float 2 can not cover light fully, light shines the aperture 11 of opposing sidewalls by the aperture 11 of shade 1 one sidewalls, aperture 11 outer ends of opposing sidewalls are connected with testing circuit 3, so that directly sense photoconductive resistance when the aperture 11 of light by a sidewall shines the aperture 11 of opposing sidewalls, illumination changes the resistance of photoconductive resistance, the voltage of this time point D changes, electric current just changes, at this moment just there is electric current to pass through capacitor C, but form electric current too a little less than, so amplify voltage and power, make alarm begin to report to the police by amplifier.
Above-described tube for transfusion expands part 4, i.e. the part of tube for transfusion buffering dropping speed.
Among Fig. 3, M is an amplifier, amplifies the effect of voltage, from the undertension of capacitor C 1 output to make alarm work, so amplify voltage by amplifier; LM386 is a power amplifier, and amplifying power drives alarm work; F is loudspeaker.
In the reality, obtaining of 5V voltage can be adopted battery, for long convenience, can insert domestic power supply 220V, then makes its voltage decreases through transformator earlier, gets final product through over commutation, voltage stabilizing again, and this process adopts chip 7805 and rectifier bridge just can realize.
The above only is preferred embodiment of the present utility model, and is in order to restriction this utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
