Abstract
The utility model relates to an infusion automatic controller for hospitals, which includes an infrared generator, an infrared receiver, an alarm, an electrically-controlled spring clip and a small ball. The small ball is arranged in an infusion bottle; the infrared receiver and the infrared generator are fixed on the spring clip; and infrared rays emitted from the infrared generator rest upon on a phototransistor. When infrared rays shone on the phototransistor are blocked by the small ball, a switch is switched on, and the alarm and the electrically-controlled spring clip are activated to perform the function of alarming and stopping infusion.
Description
Affiliated technical field
This utility model relates to a kind of hospital of infrared technology design that adopts with preventing the defeated empty automatic controller of liquid in the infusion bottle.
Background technology
At present, in the patient infusion process, whole infusion set only has infusion bottle and transfusion device two parts.Because the liquid in the effect of gravity, infusion bottle flows into human body at leisure by transfusion device, the liquid that can finish the human body external world injects in the blood of human body.Liquid in the infusion bottle closes on when being totally lost, and needs special personnel to carry out next step operation, if untimely, brings serious consequence may for the people who is infusing.But traditional transfusion device can only play the connection effect, can not send chimes of doom in time when the liquid in the infusion bottle is totally lost, and can not stop.Therefore, in a complete infusion process, the professional who changes pin or open pin need repeatedly watch the surplus of liquid in the infusion bottle, so that the controlling of next process of carrying out.The imperfection of present infusion set function is to the slightly inconvenience of life of reality.
The utility model content
In order to overcome the deficiency that existing infusion set can not send chimes of doom, this utility model provides a kind of hospital transfusion automatic controller.This hospital not only can make original infusion process normally carry out with the transfusion automatic controller, unprecedentedly sends chimes of doom and stops transfusion automatically but also liquid that can be in infusion bottle is defeated, is convenient for people to carry out controlling of next step.
This utility model is made up of infrared generator, infrared receiver, alarm, automatically controlled alligator clamp and five parts of bead.Utilize infrared generator and receptor to form a pick off simple in structure, receptor mainly adopts PNP phototriode and TWH8778 Large-power High-Speed switch integrated circuit, phototriode is except having the characteristic of light sensitive diode---and optical signal can be converted to the function of the signal of telecommunication, also have the function that the signal of telecommunication is amplified.Infrared generator mainly adopts the LED infrarede emitting diode, and it can send the infrared waves of certain frequency.When LED impinges upon on the phototriode, alarm device is not stimulated, and the infrared ray that impinges upon on the phototriode as LED is blocked, the TWH8778 switch conduction, and alarm device and automatically controlled alligator clamp are excited, and at this moment just can play the effect of reporting to the police and stopping to infuse.
Infrarede emitting diode LED and phototriode are formed infrared sensing circuit, the Infrared sent of infrarede emitting diode LED shines on the phototriode at ordinary times, its colelctor electrode output high level, make the PNP audion be in cut-off state, the switch integrated circuit control end is a low level, switch integrated circuit turn-offs, and alarm and automatically controlled alligator clamp are not worked.When the defeated sky of the liquid in the infusion bottle, the bead that floats on the liquid level has blocked the Infrared that LED sends, phototriode ends because of the irradiation of no infrared ray, the PNP base stage is in low level because of resistance eutral grounding, the rapid conducting of PNP, switch integrated circuit receives that high level control is open-minded, alarm and automatically controlled alligator clamp work because of its control end 5 feet.Powered-down switch after the people is subjected to the alarm prompting carries out controlling of next process.
Dc source, on and off switch, electric capacity, resistor is formed infrared generator, is installed in a side of mouth of infusion bottle.Phototriode, the PNP audion, the TWH8778 high speed switch integrated circuit, diode is formed infrared receiver, is installed in the opposite side of mouth of infusion bottle.The infrared ray that infrared generator is launched impinges upon on the phototriode of infrared receiver.Infrared generator and infrared receiver are fixed on the alligator clamp, and people can be clipped in it the bottle mouth position of infusion bottle.Automatically controlled alligator clamp is clipped on the transfusion device, and two alarms are installed in respectively in infrared receiver next door and the nurse's night shift room.Bead is in infusion bottle, and infrared receiver and infrared generator are fixed on the alligator clamp, and the infrared ray that infrared generator is launched impinges upon on the phototriode, and automatically controlled alligator clamp is stuck on the transfusion device, two alarms and automatically controlled alligator clamp three parallel connection.
The beneficial effects of the utility model are: simple in structure, volume is small and exquisite, is convenient to install and use, and controls infusion process automatically.This utility model in a new environment, is given its purposes widely sensor application.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
