Above-mentioned infuser with automatic alarm of stopped intravenous drip, described float locating part is be fixed on the position-limiting cover on described float sink-float storehouse, described position-limiting cover lower port sidewall is provided with opening, and while the distance limiting dropper port on float and dropping funnel top cover, the opening that sidewall is arranged refluxes for medicinal liquid.
Above-mentioned infuser with automatic alarm of stopped intravenous drip, described float exterior side wall is evenly provided with many longitudinal crest line bodies, to prevent float exterior side wall storehouse of directly rising and falling with described dropping funnel or float from contacting, reduces friction, float is sunk smoothly, and the length of float is float radial dimension more than 1.5 times.
Above-mentioned infuser with automatic alarm of stopped intravenous drip, described float sink-float upper end, storehouse and described dropping funnel grafting are fixed, the drain exit position in corresponding described float sink-float storehouse, described float bottom surface is provided with groove, float seal is provided with in described groove, described float seal form is the concentration hollow concave Rotary-table with thin film, the catheter port of drain outlet for raising up in described float sink-float storehouse, when float sinks down into float sink-float storehouse, the drain outlet in sealing member clogging float sink-float storehouse, thus prevent air from entering from both gap locations.
Above-mentioned infuser with automatic alarm of stopped intravenous drip, described float sink-float storehouse is cone-like structure, described float bottom is provided with boss, described boss is provided with the cone-shaped float seal snapped together with it, the drain that described float seal bottom is provided with storehouse of rising and falling with described float exports corresponding solid, enters from both gap locations to prevent air.
Above-mentioned infuser with automatic alarm of stopped intravenous drip, described alarm device is made up of power supply, tongue tube or magnetic switch, light-emitting component and acoustics circuit, connect with power supply one end in described tongue tube or magnetic switch one end, light-emitting component and acoustics circuit are connected in parallel on tongue tube or magnetic switch and the power supply other end.
Described alarm device is provided with the acoustic-optic alarm of tongue tube or magnetic switch in adopting, and sound, optical circuit are arranged respectively in acoustic-optic alarm, with solve acousto-optic circuit adopt a power supply time, because diode has from shwoot light characteristic, cause inside circuit to produce electric pulse and make the problem that circuit in-fighting is large, battery is short.
The invention has the beneficial effects as follows:
1, be provided with float locating part because dropping funnel and float rise and fall in inner chamber that storehouse formed, when float floats, the dropper port of buoy top and dropping funnel intercepts and comes by locating part, prevents it from affecting medicinal liquid and drips speed and be beneficial to medical personnel and observe.
2, because dropping funnel lower port is provided with storehouse of rising and falling with the float of its split, then float sink-float storehouse can adopt the hard different from dropping funnel with position-limiting cover and float and the little medical material of coefficient of friction is made, to reduce the frictional resistance in float decline process, ensure the Reliability of Microprocessor of float.
3, due to can automatically drip-stopping, automatic plugging, so after medicinal liquid be totally lost, when long-time nobody pull out pin neither enter air, also not blood back, decreases the generation of malpractice.
4, because float length is larger than radial dimension, so operation makes float more easily shake off sealing member and float to rise and fall suction that storehouse drain exports and floating rocking, more easy to operate.
Above 4 embody rational in infrastructure, the safe and reliable advantage of the present invention, really play the effect of automatically drip-stopping, automatic alarm, prevent the generation of malpractice when unmanned nurse.
