The transfusion alarm has the beneficial effects of being simple in structure and small in volume, being cable of precisely monitoring progresses of the transfusion bags of different specifications, giving an alarm in time under the preset liquid allowance, alarming to remind a nurse to turn off a valve on a transfusion pipe or pull up a transfusion needle by the combination of sound and light after transfusion is completed.

Description

A kind of infusion alarm

Technical field

This utility model relates to medical instruments field, particularly a kind of infusion alarm that utilizes the weight sensing technology.

Technical background

Venous transfusion is one of important content of nursery work, and transfusion finishes in time not found, also just can not in time change medicinal liquid or pull out syringe needle, the air intravasation can occur and form air embolism, and consequence is extremely serious, causes malpractice most probably.At present, the clinical transfusion process generally is the patient, accompany and attend to or medical personnel observe the medicinal liquid surplus at any time, and expend energy on and inefficiency are unreliable again.

At this present situation, also there are relevant transfusion care device or infusion alarm product to come out, but actually rare in the practical application.Find by consulting the Related product data, mainly there is following defective in existing infusion alarm: the product that has is to experience liquid by photoconductive resistance, but the medicine of some adding can produce color during owing to venous transfusion, makes sensitivity descend, and reports by mistake easily or fails to report; The product that has is the contact device, pollutes easily and increases the patient medical cost; The product device that has is too complicated, on the high side; Also have to be out of shape by resistance strain gage and come weighing and sensing to report to the police, but because clinical transfusion bag specification difference, treatment is different, can not cause waste according to the strict control of transfusion bag difference liquid residue.

The utility model content

The technical problems to be solved in the utility model provides a kind of infusion alarm, to overcome the deficiency of mentioning in the above-mentioned background technology.

For achieving the above object, this utility model is achieved through the following technical solutions:

A kind of infusion alarm, comprise LOAD CELLS unit, audible-visual annunciator unit and power subsystem, wherein the LOAD CELLS unit triggers the audible-visual annunciator unit by experiencing the transfusion bag weight change, and power subsystem provides power supply for LOAD CELLS unit and audible-visual annunciator unit.

Especially, described LOAD CELLS unit comprises sensor, shift fork, driving switch, spring, miniature bearing, transfusion bag hook, wherein miniature bearing is positioned at the junction point of shift fork cross bar right-hand member and shift fork montant lower end, sensor is positioned at shift fork montant upper end, the transfusion bag hook is positioned at shift fork cross bar left end, the spring lower end connects shift fork cross bar stage casing, and the spring upper end connects driving switch.

Especially, described sensor is basis weight sensor, and by the setting standard of weighing, when being lower than when presetting weight, sensor sends signal.

Especially, described audible-visual annunciator unit comprises buzzer, LED lamp, midget relay, circuit board, wherein buzzer, LED lamp, midget relay are installed on the circuit board, trigger buzzer, the work of LED lamp behind the signal of midget relay reception from sensor.

Especially, described power subsystem comprises power supply, on and off switch, opens and closes infusion alarm by on and off switch.

Especially, be provided with fixed hook on the described infusion alarm.

The beneficial effect of infusion alarm described in the utility model is: simple in structure, volume is little, can accurately monitor the transfusion bag process of different size, and in time send chimes of doom under the situation of liquid residue presetting, remind the nurse to turn off the valve on the tube for transfusion or pull out transfusion needle; In conjunction with transfusion is finished in time to report to the police, remind effect better by sound, light, avoid taking place malpractice, alleviate patient's misery.
