Description
Technical field
The invention belongs to medical instruments fields, more particularly, to a kind of infusion pump warning device and a kind of infusion pump alarm side
Method.
Background technique
Medical infusion pump mainly be precisely infused with vein, especially give emergency treatment to a patient, tumor patient and paediatrics suffer from
Using with distinctive feature in person.Infusion pump is also equipped with auto-alarm function, that is, works as other than it accurately can control transfusion speed
Automatic alarm when infusion liquid in pipe will be flow to end, to avoid blood backflow.Currently, the alarm of infusion pump mostly uses infrared ray
Device is controlled to carry out.Its principle is arranged with infrared transmitting device 102 and infrared in the two sides in the somewhere of perfusion tube as shown in Figure 1:
Line reception device 101.The infrared transmitting device 102 continuously and uninterruptedly emits infrared ray, passes through perfusion tube by the infrared ray
Reception device 101 receives.When there is liquid to flow through infrared ray, the energy of infrared ray falls a part by liquid absorption, and infrared ray connects
Receiving apparatus can receive a lesser energy value, it is assumed that be A value；When there is no liquid to flow through infrared ray, infrared receiver dress
A biggish energy value can be received by setting 101, it is assumed that be B value.Since A value and B value difference are different big, infusion pump warning device is once
It was found that becoming B value from A value, i.e., alarm at once.After medical staff hears alarm, it will come to handle.Continued with Fig. 1
Bright, perfusion tube includes transfer line 202, and the dropper 203, flow regulator 204 and the transfusion needle that are connected by transfer line 202
First 205.When infusion, infusion bottle (or infusion bag) 201 is connect with perfusion tube.Liquid level in infusion bottle (or infusion bag) 201
It is set as the first liquid level 302, it can be because constantly there is water droplet 303 to instill in dropper 203 and constantly decline.Is formed in dropper 203
Two liquid levels 301.When the second liquid level 301 drops to infrared ray or less, infrared receiver 101 is just become from original A value
B value, starting alarm.Infrared transmitting device 102 and infrared receiver 101 are set up separately the two of dropper 203 in Fig. 1
Side.Infrared transmitting device 102 and infrared receiver 101 can also be set up separately to the infusion in perfusion tube in the prior art
Any appropriate position of pipeline 202.
Controlled by infrared light infusion pump warning device has weakness to be, infrared radiation makes it possible to the generation of the ingredient in liquid medicine
Variation, and the variation is more complicated toward contact, it is difficult to it monitors, especially for the very sensitive drug of some pairs of light, than
Such as need the liquid medicine with brown perfusion tube.
Summary of the invention
In order to overcome defect existing in the prior art, the present invention is changed infusion pump warning device by original light-operated principle
