Description
Technical field
This utility model relates to a kind of alarm, relates in particular to a kind of based on a ultrared speed control system and Level Detection alarm.
Background technology
At present clinical vein transfusion mainly contains dual mode.A kind of is traditional manual type, its shortcoming is to protect constantly to make an inspection tour, also must someone accompany and attend to simultaneously, the human resources takies very large, also have and hand over the danger of infecting again, another kind is automatization's infusion pump, although this method has solved the problem that the human resources takies, but automatic infusion device cost in the market is all higher, hospital has in use increased the transfusion cost, with it the patient that this transfusion cost finally is added to, this infusion model is difficult to popularize because of the higher shortcoming of cost in practice.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure with regard to being in order to address the above problem, and is with low cost based on a ultrared speed control system and Level Detection alarm.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model comprises box body, the infrared signal modulation transmitter, infrared receiver, microprocessor, signal shaper, drip fast LCDs, liquid level is set button, electromagnetic valve and alarm, be provided with cavity in the described box body, infusion tube via hole is established respectively at the box body two ends, described electromagnetic valve is arranged on the lower end infusion tube via hole of described box body, be provided with infrared signal modulation transmitter and infrared receiver in the cavity upper inner, the outfan of described infrared remote receiver is connected with the input of described signal shaper, the outfan of described signal shaper is connected with the input of described microprocessor, the outfan of described microprocessor is connected with the input of described electromagnetic valve, the outfan that described liquid level is set button is connected with the input of described microprocessor, and the input of described alarm is connected with the outfan of described microcontroller.
Particularly, described box body lower external face arranges liquid crystal drop speed display window, drips speed setting knob, alarm, and inside is established operating circuit and held the district.
Particularly, described alarm also comprises the GPRS wireless communication device, and described GPRS wireless communication device is connected with Surveillance center wireless telecommunications.
Further, also be provided with the dropping liquid observation window on the described box body.
The beneficial effects of the utility model are:
This utility model can in infusion treatment, can not only be measured transfusion drip speed, and can be totally lost at liquid quickly and accurately, transfusion is not dripped or is infused and surpasses in the situation of dripping fast upper and lower limit, and alarm, the nursing staff of announcement, can avoid unnecessary consequence, and simple in structure, be convenient to change.
Description of drawings
Fig. 1 is the structural representation of this utility model infrared transfusion monitor alarm.
Fig. 2 is axonometric chart of the present utility model.
Among the figure: 1 ,-infusion tube via hole, 2-infrared signal modulation transmitter, the 3-infrared receiver, 4-liquid crystal drop speed display window, 5-drips speed and sets button, the 6-cavity,, the 7-circuit board holds the district, 8-electromagnetic valve, 10-box body, 11-dropping liquid observation window.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in figs. 1 and 3: this utility model comprises box body 10, infrared signal modulation transmitter 2, infrared receiver 3, microprocessor, signal shaper, drip fast LCDs 4, liquid level is set button 5, electromagnetic valve 8 and alarm, be provided with cavity 6 in the described box body, infusion tube via hole 1 is established respectively at box body 10 two ends, described electromagnetic valve 8 is arranged on the lower end infusion tube via hole 1 of described box body 10, be provided with infrared signal modulation transmitter 2 and infrared receiver 3 in cavity 6 upper inner, the outfan of described infrared remote receiver 3 is connected with the input of described signal shaper, the outfan of described signal shaper is connected with the input of described microprocessor, the outfan of described microprocessor is connected with the input of described electromagnetic valve 8, the outfan that described liquid level is set button 5 is connected with the input of described microprocessor, and the input of described alarm is connected with the outfan of described microcontroller.
As shown in Figure 2, work process of the present utility model is as follows: infrared signal modulation transmitter 2 and infrared receiver 3 are because constantly being subject to the blocking-up of drop of liquid, make infrared transmitting device 2 outfans produce a continuous pulse signal, become a DC voltage through F/V frequency/voltage changer, the size of voltage is directly proportional with the height of input pulse signal frequency.The dropping liquid number of times that shows per minute at liquid crystal drop speed display window 4, after dripping required speed of speed setting button 5 affirmations, then should be through sample-and-hold circuit and level shifting circuit, exporting upper and lower limit numerical value a to microprocessor and input value compares, when the value of inputting surpasses higher limit, namely drive electromagnetic valve 8 and adjust the control aperture, when the value of input surpasses lower level, drive the lower limit set alarm and send alarm sound.
Operational approach: suppose that liquid droping speed is 40 times/minutes, be up to 60 times/minutes, minimum is 9 times/minutes.Opening power K makes circuit working, regulates to drip the fast knob 5 of setting, and liquid crystal drop speed display window 4 is set when being designated as 9 times, and at this moment, the nursing staff can regulate a speed by the control valve on the tube for transfusion, is assumed to be 40 droplets/minute herein, and transfusion is in normal operating conditions.In case drip speed be lower than 9 droplets/minute or be higher than 60 droplets/minute all can the trigger alarm device.
Alarm also comprises the GPRS wireless communication device, and the GPRS wireless communication device is connected with Surveillance center's wireless telecommunications of night shift room, also is provided with dropping liquid observation window 11 on the box body.
