Abstract
The utility model discloses an alarm device for venous transfusion. A hanging ring (7), a hook (8), signal indication screens (3) (4) (5), a switch (6), a time adjusting knob (2), a shift switch (9) are arranged on a box body (1). A circuit board is arranged in the box body (1). A circuit which is composed of a photoelectric coupling circuit, a magnifying driving circuit, a time delay circuit, an acoustic circuit, and an acoustic-optic circuit is arranged on the circuit board. The alarm device can send out secondary alarm signals when transfusion liquid has remanent liquid ranging from 15 ml to 20 ml. The utility model can prompt medical personnel or nursing personnel to pull out needle heads or to replace medicine liquid, and can avoid that the phenomenon of the injection of air when a transfusion bottle is empty because of negligence or the phenomenon of blood return occur.
Description
This utility model belongs to the auxiliary device of the venous transfusion when importing medium in the human body, is specially the venous transfusion attention device that can send the acousto-optic warning signal when a kind of venous transfusion is waited to infuse end to people.
Vein drip transfusion is the indispensable link that the patient treats of curing the desease, before every bottle (bag) transfusion input human body finishes, pull out infusion needle or change other medicinal liquid continuation transfusion before all will notifying medical worker or nurse to come bed, its objective is and all to be totally lost the bottle herb liquid, can not fan the air again and inject air or produce the blood back phenomenon and cause adverse consequences.When therefore the medicinal liquid in infusion bottle soon is totally lost, no matter be that medical worker or nurse personnel notice very that this constantly.But the medicinal liquid that under certain situation and condition, fans the air phenomenon also can happen occasionally.To so far, also find no the venous transfusion attention device that can send alarm signal when venous transfusion finishes to people.
The purpose of this utility model provides a kind of venous transfusion attention device, when transfusion soon finishes, this venous transfusion attention device can send alarm signal to people, medical worker or nurse personnel can extract infusion needle or change other medicinal liquid and continue transfusion, just can avoid injecting the generation of air or blood back phenomenon, can avoid the generation of adverse consequences fully owing to fanning the air appears in carelessness.
To achieve these goals, this utility model is to be equipped with thereon in the box body of hook, indicator panel, switch and shift switch, be equipped with circuit board, circuit board is provided with the circuit of being made up of infrared electro coupling circuit, amplification driving circuit, delay circuit, acousto-optic generation circuit and sound generating circuit.
This venous transfusion attention device is hung on the infusion support, under hang drip medicinal liquid bottle, it can be totally lost as yet at every bottle liquid medicine and carry out warning the first time pre-plate when also having certain surplus (15-20ml) earlier, carry out the caution forecast second time again after a period of time (2-5 minute), when messenger pulls out syringe needle or changes medicinal liquid, close swap switch and can stop to warn pre-plate.When transfusion when soon finishing, this attention device can in time send alarm signal, just can stop the generation of injection air or blood back phenomenon because fanning the air appears in carelessness.
