Description
Technical field
This utility model relates to a kind of medical monitor, relates in particular to a kind of medical infusion lines bubble monitor.
Background technology
Current, in the many employings of hospital's transfusion intravenous drip mode, although medical personnel drained the air bubble in the tube for transfusion before instiling as far as possible; Yet because in infusion process, still can there be the indefinite air bubble of the quantity that differs in size in multiple factor affecting in tube for transfusion; These bubbles are with in the medicinal liquid input human vein; Sometimes the blood capillary microcirculation is impacted, especially when air bubble is big, may cause capillary embolism; Influence blood flow, cause phenomenons such as dizziness, spasm when serious.Because people can not notice air bubble all the time when transfusion; Therefore often find it is not so timely; When having the on the scene or patient of nursing staff conscious; Perhaps, air bubble in the tube for transfusion can be avoided being transfused in the vein, and when patient's stupor or unmanned in the dead of night nurse on the scene, it is just bigger to take place together to import patient's venous chance than big air bubble with medicinal liquid.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of medical infusion lines bubble monitor is provided, and it has novel structure, the highly sensitive advantage that can detect automatically and report to the police.
To achieve these goals, this utility model adopts following technical scheme:
A kind of medical infusion lines bubble monitor; It comprises in shell and the shell and is provided with control circuit; On shell, being provided with the pick off, the said pick off that cooperate with tube for transfusion is connected with control circuit; Control circuit is connected with alarm, and control circuit also is connected with input power cord, and shell and input power protection ground are altogether.
Described pick off is a ultrasonic sensor, and it comprises that ultrasonic emitting pick off and ultrasound wave accept pick off.
Described control circuit comprises master controller, is connected with rectifier power source and battery on the described master controller, and wherein battery is connected with master controller with rectifier power source respectively, and master controller is connected with alarm, running indicator and power supply indicator; Master controller also is connected with on and off switch and reset key, and connecting terminal block is connected with master controller through AD converter, and the ultrasonic emitting pick off is accepted pick off with ultrasound wave and is connected with connecting terminal block.
Described alarm is an audible-visual annunciator.
Described battery is a lithium battery.
The beneficial effect of this utility model:
1 adopts ultrasonic sensor to increase the sensitivity of monitoring.
2 utilize main controller controls to realize the function of bubble in the automatic monitoring transfusion pipe.
3 realize finding the function of tube for transfusion bubble warning.
