Description
This utility model relates to the kettle that drips on a kind of transfusion device that uses in curative activity.
The transfusion device that uses in curative activity all has these parts of kettle of dripping.A critical function that drips kettle is the speed of demonstration transfusion, drops in dripping in the unit interval by an observation water-in-kettle and counts, and promptly can know transfusion speed at that time.Know that a water-in-kettle drops in the number that drips in the unit interval, can use stalagmometer to count device.Write down the water droplet number and count device with stalagmometer, must have can be used for counting drip signal.Can become the action that water droplet falls the device of utilizable count signal, we claim it to be the pick off that drips.The transfusion device stalagmometer that uses in curative activity is at present counted device, and its pick off that drips all is a photo-electric.It is in a side of dripping kettle a luminous source to be set, and at the offside that drips kettle a photocell is set, and when the light beam that sends from light source was penetrated on photocell, photocell promptly had electric current output.And this road light beam is just on the only way which must be passed that water droplet falls, water droplet whereabouts temporarily shielding has also reflected the light beam that shoots to photocell from light source, and photocell did not receive light at that time, temporary transient no current output, water droplet light beam is later penetrated again, and photocell just has electric current output again.Because the fluctuation that water droplet falls the photocell output current that causes promptly can be used to water droplet is counted.The drip light beam that light source sent of pick off of photo-electric, want see through to drip Hu Bi twice and cause decay, the optoelectronic transformation efficiency of adding present photocell is very low, this light that just requires light source and sent must be stronger, otherwise just can not after see through dripping Hu Bi twice, still can make the electric current that photocell produces Practical significance.Satisfy requirement, the power supply of enough power must outfit can be provided luminous source.So count device and usually want backguy to connect civil power to make power supply, perhaps make power supply, could guarantee its long-time operate as normal with the bigger accumulator of volume with the drip transfusion device stalagmometer of pick off of photo-electric.So make and count with the drip transfusion device stalagmometer of pick off of photo-electric that the volume of device is big, manufacturing cost is higher, it is also inconvenient to use, and has limited its popularizing in curative activity.How to change the transfusion device stalagmometer and count the shortcoming that device brings because of the pick off that drips? at all relevant before this domestic patent documentation of in March, 2000 retrieval, we still do not find any information of relevant this respect.
The purpose of this utility model is to provide a kind of improved transfusion device to drip kettle, and it can be transformed into sound dripping the water-in-kettle kinetic energy that falls that drips, and passes to the outside of dripping kettle, for the water droplet counting provides not consumed power of signal.
The purpose of this utility model is achieved like this: transfusion set drip kettle be by have water inlet pipe drip Hu Ding, have outlet pipe drip at the bottom of the kettle and cylindraceous kettle body between the two constitutes at them, and this utility model is to have opened a side opening on the kettle body dripping, and has placed one by the tubular voice tube with cover the sound transducer that drips that the flat film on the voice tube constitutes in dripping kettle by this side opening.
Drip its external diameter of tubular voice tube of sound transducer less than the internal diameter that drips the kettle body, and its end is dripping kettle inside, and its opening tilts, the inclined-plane is towards dripping a Hu Ding, be positioned at water inlet pipe under, and covered fully by flat film, its other end opens wide outside dripping kettle.Like this when water droplet when water inlet pipe falls, just in time drop on the flat film, make it produce vibrations.The vibrations of flat film make and produce the sound that water droplet falls in the voice tube, and this sound that drips passes to by voice tube and drips outside the kettle, promptly are to be used to signal that water droplet is counted.Because the external diameter of voice tube less than the internal diameter that drips the kettle body, has so just been reserved some spaces between a voice tube and a kettle body, pass through smoothly to guarantee the physical ability of being infused.Because flat film covers above the opening that voice tube tilts, after water droplet is fallen flat film, can flow down rapidly and do not stop.
The side opening that drips on the kettle body is out in the middle and lower part of dripping the kettle body, make the sound transducer of putting in the kettle by side opening that drips one segment distance be arranged with the water inlet pipe that drips Hu Ding, this segment distance is no less than 3 centimetres, to guarantee that water droplet has possessed more kinetic energy when landing this segment distance, could produce the acoustical signal of Practical significance like this when water droplet is fallen on the sound transducer that drips; Drip sound transducer with drip kettle at the bottom of also a segment distance to be arranged, this segment distance is no less than 1 centimetre, so that observe the height that drips the water-in-kettle face, prevents to drip gas in the kettle and enters the outlet pipe that drips at the bottom of the kettle.
The sound transducer that drips is self to be fixed on tight connection of dripping the kettle body side hole and with it by its voice tube to drip on the kettle.
Drip sound transducer except its a transaudient mouth of pipe that drips the kettle outside opens wide, remainder all is airtight.
Like this when the sound transducer that drips is fixed on the kettle, drip gas in the kettle and liquid that can not by dripping sound transducer and leak into the junction of dripping kettle wall side opening and to drip a kettle outside, the gas that drips the kettle outside can not enter by same position yet and drip kettle inside.
Because this utility model is to have increased the sound transducer that drips in the inside that general infusion set drips kettle, it can be transformed into sound dripping the water-in-kettle kinetic energy that falls that drips, and passes to and drip a kettle outside.The sound that this produces because of dripping, becoming by microphone can be for the signal of telecommunication of rolling counters forward, and this process is consumed power not.And the pick off that drips of photo-electric produces and can but will consume more electric energy for the signal of telecommunication of rolling counters forward.Therefore count device with being arranged on the transfusion device stalagmometer that transfusion device drips the sound transducer that drips in the kettle, count device, can reduce the consumption of much electricity than the transfusion device stalagmometer of the pick off that drips with photo-electric.Make power supply with a common collection layer battery and promptly can guarantee its long-time operate as normal, needn't backguy connect civil power and make power supply, also needn't be equipped with the accumulator that volume is big, price is expensive and make power supply.So just the volume that can make the transfusion device stalagmometer count device reduces, cost reduces, it is more convenient to use, and is more conducive to its popularizing in curative activity.
