Abstract
The invention relates to a drip transfusion early-warning device. The early-warning device comprises a box body, a transfusion hosepipe, a transfusion glass pipe, a heating resistance wire, a loudspeaker, an automatic switch and a battery, when the infusion pipe is filled with a liquid, an elastic airbag is in an expansion state, two metal sheets A arranged on the elastic airbag are respectively contacted with corresponding metal sheets B, at the moment, the working circuit is formed by connecting the battery and the heating resistance wire in series, the loudspeaker is not electrified, and the heating resistance wire can heat after being electrified, so that the temperature of a medical liquid passing through the transfusion glass pipe rises; when the transfusion is about to finish, the elastic airbag is changed into a contraction state, the two metal sheets A arranged on the elastic airbag are respectively not in contact with the corresponding metal sheets B, at the moment, the working circuit is formed by connecting the battery, the heating resistance wire and the loudspeaker in series, the loudspeaker produces a sound after being electrified, so as to remind the medical workers of performing further treatment, avoid the conditions of blood return and the like after the liquid in the infusion bottle is transfused, and further avoid damage to the body of a patient, and meanwhile the workload of the medical workers is reduced.
