Technical field:
This utility model relates to a speed of monitoring medical Transfusion device and the electronic-controlled installation that transfusion finishes warning.
Background technology:
Present medical Transfusion device only has the simple function for patient transfusion, when the nursing staff just when care of patients or relatives and friends visit patient mutually talk, often because carelessness and can not find in time that transfusion finishes makes troubles for patient and nursing staff.On the other hand, the nurse adjusts transfusion device and drips speed, particularly during the transfusion drip speed of old people and infant, often accurately adjusts with reference to wrist-watch and drips speed, and is both loaded down with trivial details, time-consuming again.And the device kind of monitoring medical Transfusion device at present is more, be sample objects how with medicinal liquid flow or liquid fluctuating, but all exist not enough, mainly show as under long ultrasound wave or illumination effect, might cause some drugs character to change, and the apparatus structure complexity, cost is higher, should not popularize.
Summary of the invention:
The purpose of this utility model is that a kind of medical Transfusion device monitoring infusion device will be provided, the vibration that medicine liquid droplet falls to producing during its energy perception transfusion device work, thus by electronic control circuit infusion process is implemented to monitor.
The purpose of this utility model is achieved in that the vibrating sensor outfan is electrically connected with the signal amplifier input, the signal amplifier outfan connects to control circuit, signal amplifier and control circuit connect working power and (need connect power supply as vibrating sensor during work, then vibrating sensor also connects power supply), contact with the housing of medical Transfusion device dropping funnel during vibrating sensor work.
Owing to adopt such scheme, make and adopt the control circuit infusion monitoring device duty of vibrating sensor and amplifier thereof to become possibility, and simple in structure, reliable operation, with low cost, being convenient to promote, better is the extensive patients service, on the other hand owing to do not relate to factors such as ultrasound wave or illumination, can not cause the character of some drugs to change, and vibrating sensor is installed in the dropping funnel outside again, does not contact medicinal liquid, thereby has good safety.
