Abstract
The utility model discloses an infrared ray intravenous injector alarming device which can be sleeved outside a dropping funnel of an infusion tube of an injector and is controlled by a passive infrared switching circuit. The alarming device is characterized in that the size is smaller, the use is convenient and secondary utilization is realized; the alarming device takes the shape of a sleeve and is convenient to mount and dismount; power supply equipment adopts two button cells, and the on/off of the power supply and the reset of an alarm system can be realized only through an isolated movable stirring piece, and the operation is convenient and safe; and a slide resistor is arranged in a loudspeaker position, and the volume adjustment in a certain range can be realized through an external slide block so as to ensure the alarming effect within a certain distance and to avoid that the alarming device in the small space disturbs the patient in distance place. When the liquid level of the dropping funnel of the intravenous infusion injector is lower than a photosensitive device, an infrared ray receiving device receives the infrared rays, and the alarming device is controlled to be started through a power switch integrated circuit to give an alarm that the intravenous infusion is completed.
Description
01. technical field
The design belongs to medical instruments field, relates to a kind of intravenous injector alarm device.
02. background technology
At present, the transfusion device of hospital and all kinds of medical institutions use is traditional disposable transfusion device at home.The composition of this transfusion device has a bottle pin, air inlet needle, tube for transfusion, Murphy tube, transdermal pin.When transfusion is carried out, need medical personnel's nurse, transfusion need in time be pulled out the transdermal pin after finishing.If transfusion has finished but in time not found, may produce blood back and entry needle blood coagulation and block.And existing various types of loaded down with trivial details like the complicated installation of alarm device certain structures, if want the higher processing difficulties of invested in plant production cost.In addition, most alarm device operation principle is complicated, and used power supply provides volume larger by several sections of batteries, again or the volume of alarm device fix, the alarm scope has certain limitation.
03. summary of the invention
In order to overcome defects, this utility model provides a kind of lightweight and portable in volume, uses safety and easy to operate infrared ray infusion alarm.This device is reported to the police by passive type infrared switch control circuit UNICOM, and its profile is cylindric, can retaining ring in the outside of tube for transfusion dropping funnel, realize reporting to the police timely, also can utilize by two degree.The inside loudspeakers of this alarm device is equipped with small-sized slide rheostat, by the volume adjusting of outside small slide block realization certain limit, guarantees the alarm effect of certain distance, prevents that alarm device is noisy to remote patient in little space.The power supply of this device is provided by two button cells, only can realize the switch of power supply and resetting of warning by a slip plectrum.In addition, this utility model also together installs button cell and plectrum in battery case, has not only dwindled whole volume and has also alleviated weight.
The design's advantage is: at first the design's shape and dropping funnel appearance similar, convenient install and also volume light and handy.Utilize passive infrared switch controlling device, operation principle is simple.The power supply of device is provided by button cell, and volume is little.And the switch of power supply and ann reset switch are realized by the plectrum of insulation, and be easy to operate.Speaker also has the volume adjusting slide block, can regulate according to specific environment the size of audio warning.
04. description of drawings:
Below in conjunction with drawings and Examples this utility model is further specified.
Figure one: this figure is the main part of device, for overall structure that device is described and the position relationship of each several part
Figure two: this figure is the top view of device, in order to illustrate that RF transmitter (3) and receptor (6) are relative position
Figure three: this figure is circuit diagram, in order to be briefly described the structure and distribution of internal circuit
05. the specific embodiment:
When beginning transfusion is buckled in the dropper place of intravenous from device running-on (1) with whole plastic casing (2), mobile plectrum (7) energized, and device is opened.Infrared transmitting device on the device (3) and signal receiving device (6) keep the relative position of same level line.Because dropping funnel contains medicinal liquid, infrared ray reflected, and does not report to the police so receiving device receives signal when transfusion was carried out.And when the liquid level at venous transfusion syringe dropping funnel place was lower than infrared facility place (3) and (6), infrared receiver received signal, opened through on and off switch integrated circuit control alarm device (4).Can mediate to the small-sized slide rheostat (8) that inside loudspeakers is installed by reconciling speaker volume adjusting slider (5), realize the volume adjusting of certain limit.Button cell (9) together installs in battery case (10) with plectrum (7).
Claims (4)
1. infrared ray intravenous injector alarm device is reported to the police by passive type infrared switch control circuit UNICOM, and it is characterized in that: its profile is cylindric, can retaining ring in the outside of tube for transfusion dropping funnel, realize reporting to the police timely.
2. infrared ray intravenous injector alarm device according to claim 1, it is characterized in that: the inside loudspeakers of this alarm device is equipped with small-sized slide rheostat, can realize the volume adjusting of certain limit by an outside small slide block.
3. infrared ray intravenous injector alarm device according to claim 1, it is characterized in that: the power supply of this device is provided by two button cells, and the move left and right by the slip plectrum can realize the switch of power supply and resetting of warning.
4. infrared ray intravenous injector alarm device according to claim 1 is characterized in that: button cell and plectrum are together installed in battery case.
