Abstract
The utility model provides a simple intravenous injection annunciator, which can control the pre-warning time according to the requirement of a patient humanely, can be fastened on a infusion catheter, can move up and down, can control a switch according to the intensity change of the light beam, has high precision, can give an alarm in advance, and has low cost. The simple intravenous injection annunciator is characterized in that the simple intravenous injection annunciator is internally provided with a power supply that is connected in parallel with an LED (light-emitting diode) lamp; an emitter of a triode is grounded; a collector of the triode is connected with one end of a horn; a base of the triode is connected with a nand gate output terminal; and the other terminal of the horn is connected with a variable resistor. In the simple intravenous injection annunciator, a photoresistor is connected with two input terminals of a nand gate. The shell is a non-transparent plastic small box. A groove is arranged on one surface of the box; a button type switch is arranged on the other surface of the box. The LED lamp is arranged close to the left end of the groove of the box; the right end of the groove of the box is connected with the phtoresistor and a buzzer; and the box is also internally provided with a resistor, a button battery, the triode, a conducting wire and an and element. The simple intravenous injection annunciator has the advantages of simple and novel structure and is suitable for intravenous injection.
Description
Technical field
This utility model relates to the medical safety engineering, belongs to the medical safety assistive device
Background technology
Transfusion has another name called has an intravenous drip or hangs water.Be to import intravital heavy dose (single administration is more than 100ml) injection by intravenous drip.Be packaged in the infusion bottle or bag of glass or plastics, do not contain antiseptic or antibacterial.Drip speed by the transfusion device adjustment during use, continue and stably enter vein, to replenish body fluid, electrolyte or nutrient substance is provided.
Between the short more than ten years, be accompanied by the carrying out of medical reform, China becomes the world premier " transfusion big country ".China is populous nation, and China in 2009 consumes 10,400,000,000 bottles of drops according to incompletely statistics, and what allow more the people worries is annually also to increase with 30% speed.
The safety problem of transfusion causes compatriots' strong interest, several numerals that National Development and Reform Committee revealed out before deputy director Zhu Zhixin year in the 18 meeting of 11 Standing Committee of the National People's Congress: China's medical transfusion was 10,400,000,000 bottles in 2009, everyone has failed 8 bottles of liquid to be equivalent to 1,300,000,000 populations, is higher than 2.5 to 3.3 bottles level in the world far away
Transfusion safety problem incident with it allows the people very worry, and a lot of people can have such experience, and sleepy is felt and dare not be slept in getting process ready, in case overslept safety problem will take place.When flow of liquid is intact, the blood back phenomenon takes place easily, to solidify the back and stop up tube for transfusion, influence continues transfusion.And pressure transfusion is when flow of liquid is intact, and air can be pressed into blood vessel, and aeroembolism takes place, and works the mischief to life.
Therefore when patient infusion is had an intravenous drip, need the entourage to note remaining amount of liquid medicine at any time, caused very large manpower loss.
Yet the more existing siren of having an intravenous drip exist can not with patient's control how long in advance ring, complicated, degree of accuracy is not high, cost is crossed problems such as height.Do not meet the requirement of the sustainable development low-carbon (LC) of current era.
Summary of the invention
This utility model is in order to solve an above-mentioned difficult problem, but provide a kind of hommization ground with patient's control how long in advance ring warn, can be held in moving up and down, can utilize light strong and weakly to change gauge tap, have that the pre-ahead of time ring in pinpoint accuracy ground is warned, the low cost simple siren of having an intravenous drip above the tube for transfusion.
The simple and easy siren of having an intravenous drip, comprise this product casing, photoconductive resistance, buzzer, LED, resistance, button cell, audion, lead and gating element, it is characterized in that: power supply and the parallel connection of LED lamp are equipped with in an inside, transistor emitter ground connection, colelctor electrode connects an end of loudspeaker, base stage connects the NAND gate outfan, another termination variable resistance of loudspeaker.Photoconductive resistance connects the simple and easy siren of having an intravenous drip of two inputs of NAND gate.
The simple and easy siren of having an intravenous drip is characterized in that: shell is the opaque-plastic etui.The one side of box has groove, and another side has push-button switch.
The simple and easy siren of having an intravenous drip is characterized in that: the left end near the box groove is equipped with the LED lamp, and its right-hand member has been connected with photoconductive resistance and buzzer, and resistance, button cell, audion, lead and gating element also are housed in the box.
It has mainly solved three difficult problems this utility model: the firstth, and patient's worry to infuse problem device of blood back can utilize that light is strong and weak to be changed the pre-ahead of time ring caution of gauge tap pinpoint accuracy and remind patient; The secondth, but general precaution device can not regulate and control the problem device of time length can hommization ground how long ring in advance with patient's control and warn.
Description of drawings
Fig. 1 is an outboard front view of the present utility model; Fig. 2 is the external right view.Comprise (1) fixed groove (2) display lamp (3) switch; Fig. 3 is this utility model interior arrangement circuit diagram
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further specified.
Just shown in Figure 2 as Fig. 1, when using this utility model, at first open switch, after display lamp lights, just this utility model can be buckled on the tube for transfusion.Use this utility model, can move the position of this product on tube for transfusion according to the actual length of wanting to control pre-warning time of patient, easily and effectively.
Just this utility model internal circuit principle is at the left end near the box groove LED lamp to be housed as shown in Figure 3, its right-hand member has been connected with photoconductive resistance and buzzer, have flow of liquid out-of-date in tube for transfusion when LED lamp behind the switch open lights, the intensity of light arrives the photoconductive resistance at this moment of right-hand member place through tube for transfusion and does not start prior-warning device greatly.When no liquid flow through in the tube for transfusion, the intensity of light grow arrived right-hand member place photoconductive resistance at this moment diminishing startup prior-warning device buzzer through tube for transfusion and sounds, and produces the effect of reminding patient.
