The device further comprises an elastic component (2) which is downward perpendicularly, the gravity sensor is connected with the elastic component (2), and an infusion container (3) is arranged at the lower end of the elastic component (2). The device can effectively reduce false alarms, the false alarm phenomena caused by fog in a drip cup when the device is used for a long time can not occur, and the false alarm phenomena due to the fact that the liquid level is too high or too low in the drip cup can not occur. In addition, through utilization of the gravity sensor, such as a magnetic resistance sensor or a resistance strain gauge sensor, the device is high in integral accuracy, can timely detect the current flow speed, and can give an alarm on the fact that the flow speed is out of control.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of device of realizing the infusion flow rate feedback by the weight that detects infusion vessel.
Background technology
Infusion pump is a kind ofly can accurately control number of infusion drops or infusion flow rate, guarantees that medicine is can speed even, and dose accurately and safely enters a kind of instrument that plays a role in the patient body.
Infusion pump be a kind of be the automatic infusion device of consumptive material with the transfusion device, compare with traditional infusion mode, have precision height, flow rates wide, big positive pressure can be provided, have the characteristics of more complete warning.But in clinical use, there is the problem of a safety perplexing user and product designer always.Because infusion pump comprises mechanical moving element, the electronic circuit part, the control software section certainly exists the infusion velocity control abnormity in actual use, can not pump into problems such as medicinal liquid, deadlock.Wherein infusion flow-rate makes infusion pump have flow velocity potential safety hazard out of control unusually in real work.In order to address this problem, each producer mainly adopts and drips number sensor transfusion devices and drip drop drippage situation in the kettle at present, and by with the control system communication of infusion pump, thereby in time find the situation that flow velocity is out of control.But owing to drip liquid level in the kettle, drip factor such as haze in the kettle and can cause that dripping the frequent flase drop of number pick off surveys.
The utility model content
At the prior art defective, the purpose of this utility model is to provide a kind of device of realizing the infusion flow rate feedback by the weight that detects infusion vessel, this device can be measured accurately to infusion flow rate, the feedback of real-time flow rate is provided for infusion pump, reduce the flow velocity risk of bringing out of control, and can effectively improve the safety of transfusion.
This utility model is to solve the problems of the technologies described above the technical scheme that adopted as described below:
A kind of device of realizing the infusion flow rate feedback by weight detecting, comprise alarm unit and control unit, alarm unit is connected with control unit, it is characterized in that: described control unit comprises single-chip microcomputer and displacement measurement unit, in inside, displacement measurement unit gravity sensor is set, described device also comprises elastomeric element vertically downward, and gravity sensor is connected with elastomeric element, in the lower end of elastomeric element infusion vessel is set.
Further, described gravity sensor is magnetoresistive transducer or resistance strain gage pick off.
Further, described device is connected with infusion set by communication line.
Further again, described communication line is communication cable, WIFI or infrared ray.
The beneficial effects of the utility model are as follows: the weight of passing through the detection infusion vessel that this utility model provides realizes the device of infusion flow rate feedback, can effectively reduce false alarm, when long-time the use, can not haze in the kettle and the phenomenon of false alarm occurs, can not occur yet because drip the excessive height of liquid level in the kettle or cross low and the phenomenon of false alarm occurs because of dripping; In addition, owing to adopt gravity sensor, as magnetoresistive transducer or resistance strain gage pick off etc., it is higher therefore to install overall precision, can in time detect current flow rate regime, makes warning to flow velocity is out of control.
Description of drawings

Fig. 2 is the principle schematic of the device that provides of this utility model;
Fig. 3 is that this utility model utilizes the structural representation of magnetoresistive transducer as embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in detail.
A kind of device of realizing the infusion flow rate feedback by weight detecting, as depicted in figs. 1 and 2, comprise alarm unit 7 and control unit 1, alarm unit 7 is connected with control unit 1, described control unit 1 comprises single-chip microcomputer 8 and displacement measurement unit 9, in 9 inside, displacement measurement unit gravity sensor 10 is set, gravity sensor 10 can be magnetoresistive transducer or resistance strain gage pick off, described device also comprises elastomeric element 2 vertically downward, gravity sensor 10 is connected with elastomeric element 2, in the lower end of elastomeric element 2 infusion vessel 3 is set.
Device described in the utility model is connected with infusion set 6 by communication line 4.Communication line 4 can be communication cable, WIFI or infrared ray.Described infusion set 6 inside comprise motor 11 and alarm unit 12.
In one embodiment, describe as gravity sensor with the reluctance type displacement transducer:
As shown in Figure 3, elastomeric element 2 is connected on the cross bar 5 that hangs infusion vessel, and infusion vessel 3 is connected the below of elastomeric element 2.Elastomeric element 2 stressed generation distortion, after reluctive transducer 10 in the displacement measurement unit 9 is measured the displacement of elastomeric element 2, the just profound ripple signal of output two-way is to single-chip microcomputer DA, single-chip microcomputer calculates poor between the two paths of signals numerical value then, thereby obtain the shift value of magnetic resistance displacement transducer, calculate the value of thrust of current elastomeric element 2 again according to shift value, and then obtain the value of the surplus in the infusion vessel 3.Last again and the value of the infusion vessel surplus that obtains of last time and calculate infusion flow rate the blanking time between twice measurement.
This utility model is a flow velocity of measuring liquid by the mode of weighing, when the flow velocity that detects when setting flow velocity, the alarm unit 7 of device itself sends warning, and for example: communication cable by communication line 4(, WIFI, infrared ray etc.) data are sent on the infusion set 6, infusion set 6 can be fixed on certain position by fixture 13, and infusion set 6 carries out respective handling (for example: stop motor 11 rotations or alarm 12 etc.) after receiving information.
The weight of passing through the detection infusion vessel that this utility model provides realizes the device of infusion flow rate feedback, can effectively reduce false alarm, when long-time the use, can not haze in the kettle and the phenomenon of false alarm occurs, can not occur yet because drip the excessive height of liquid level in the kettle or cross low and the phenomenon of false alarm occurs because of dripping; In addition, owing to adopt gravity sensor, as magnetoresistive transducer or resistance strain gage pick off etc., it is higher therefore to install overall precision, can in time detect current flow rate regime, makes warning to flow velocity is out of control.
It should be noted that; above-mentioned specific embodiment only is exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion all drop in the protection domain of the present utility model.It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, are not to be used to limit this utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
