Abstract
The utility model relates to an alarm for venous transfusion, which comprises a photoelectric sensor 1 and a transfusion tube 3 fixed between the mouth of a drug bottle and a Murphy's dropper, wherein, the photoelectric sensor is connected with a light alarm circuit or a sound alarm circuit. The utility model is characterized in that the alarm for venous transfusion can send light or sound alarm in time to remind the patient and the medical staff when the transfusion ends. The alarm for venous transfusion has sensitive reaction, decreases the working intensity of the medical staff, and prevents the patient from being unnecessarily involved in the management on transfusion.
Description
This utility model relates to a kind of medical intravenous transfusion alarm.
In daily medical procedure, during venous transfusion, the nursing staff is the transfusion time of grasping each patient according to set medicinal liquid flow velocity (drip speed/minute), and is not only loaded down with trivial details, and not very reliable (patient may change flow velocity midway).Be generally when preventing that transfusion from finishing, can not in time be handled (pull out pin or change dressings) patient need participate in the transfusion progress and observe, because transfusion time is longer, certainly will increase burden to patient, also due to illness sleeping or other reason of people finds in time that transfusion finishes, and adverse consequencess such as blood backflow take place.
This utility model purpose is to overcome above-mentioned transfusion and finishes and do not have the shortcoming of automatic alarm, a kind of intravenous transfusion alarm is provided, this alarm device can in time send alarm signal when transfusion finishes, remind patient or directly notify medical personnel, guarantees time enough processing patient's curative activity, and it is simple in structure, at the bottom of the cost, medicinal liquid is not contacted pollution-free, can not influence medicinal liquid, reach and alleviate medical personnel's labor intensity, the purpose of psychological burden in the elimination patient infusion process.
Intravenous transfusion alarm of the present utility model comprise by the light emitting diode 4 that can luminously pass liquid and the phototriode 5 of accepting optical signal respectively level place the both sides on tube for transfusion 3 surfaces to constitute photoelectric sensor 1.Comprise that also a light tight shell is coated on the photoelectric sensor 1, in photoelectric sensor 1 join dependency sounding alarm or the luminous warning circuit 2, under the normal infusion situation, tube for transfusion 3 is full of medicinal liquid, but the light level that light emitting diode 4 sends is passed medicinal liquid and is shone on the phototriode 5, phototriode 5 is in conducting state, when the bottle inner liquid medicine is used up, when the medicinal liquid face of tube for transfusion 3 drops to the horizontal plane of photoelectric sensor 1, because the capillarity of medicinal liquid face in tube for transfusion 3, the medicinal liquid face is spill, deviation takes place during by tube for transfusion 3 in the light that light emitting diode 4 sends on concave panel, phototriode 5 loses illumination and is in cut-off state, after the medicinal liquid face passes through the horizontal plane of photoelectric sensor 1, the light that light emitting diode 4 sends can pass tube for transfusion 3 again and shine phototriode 5, and phototriode 5 recovers conducting state.Therefore phototriode 5 experienced a conducting, by, turn on process, on photoelectric sensor, obtain an electric pulse, i.e. signal is finished in transfusion.Remind patient, medical personnel by relevant sounding alarm or light emission alarm device.
Described intravenous transfusion alarm can in time be reported to the police when transfusion is finished, and calls out patient and medical personnel.Adopt this intravenous transfusion alarm, be quick on the draw, reduce medical personnel's work difficulty.Avoided patient in the managerial unnecessary participation of transfusion.
Below in conjunction with description of drawings this utility model.
Fig. 1, this utility model intravenous transfusion alarm structural representation.
Fig. 2, this utility model intravenous transfusion alarm light sensation sensor construction sketch map
As shown in Figure 1, this intravenous transfusion alarm is made of with relevant warning circuit 2 photoelectric sensor 1, and photoelectric sensor 1 is fixed on the tube for transfusion 3.
As shown in Figure 2, the medicinal liquid face is when the photoelectric sensor 1, because capillarity is spill at tube for transfusion 3 Chinese medicine liquid levels, the light generation deviation that light emitting diode 4 sends loses illumination and ends at the phototriode 5 of tube for transfusion 3 heteropleurals.
Claims (1)
1, a kind of intravenous transfusion alarm is characterized in that: photoelectric sensor is fixed on the tube for transfusion between medicine bottle mouth and the Maufee type dropper, in photoelectric sensor join dependency sounding alarm or the luminous warning circuit.
