Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to one kind can be defeated by being protected from light for pressure sensitive early warning liquid level
Liquid device.
Background technique
Infusion apparatus is a kind of common medical instrument, and bag transfusion system be it is one such, be widely used in west
The various medical spaces in southern area are after infusion apparatus is inserted into medicine bottle, before carrying out human body puncture, it is necessary to make infusion apparatus when in use
Full medical fluid has no gas bubbles left, causes blood vessel embolism dead to prevent bubble to be entered in tissue, which is known as
Exhaust.
Venous transfusion is one of the most common type treatment means in modern medicine, it be allowed in a manner of intravenous injection drug with
Blood Rapid Circulation reaches as the whole body cures purpose.Since venous transfusion duration is generally long, and herein
Medical staff whole can not guard again in the process, fail to take needle to cause to hurt to human body in time to prevent drug conveying from finishing
Therefore evil is necessary the monitoring and alarm of infusion progress.Wherein using pressure sensor to medical fluid face height change
Monitoring is a kind of more feasible way.
The drug for needing lucifugal infusion of existing clinical use is more, commonly are as follows: sodium nitroprussiate, nitroglycerin etc., defeated
During liquid, when being protected from light bag package medicine bottle because using, while being instiled using light proofing infusion apparatus, such as evening or insufficient light
Condition when, the puzzlement that whether terminates of infusion, therefore, urgent clinical needs can not effectively be observed by usually bringing to patient and medical staff
It is a kind of effectively early warning to inform that patient or medical staff are transfused the special infusion apparatus for being protected from light liquid.
Summary of the invention

Kind.
When carrying out venous transfusion, the liquid level of injection can constantly decline.It is closed according to liquid pressure and liquid level
System is it is found that the pressure at the liquid level of bottom also can constantly reduce, therefore, the measurement by pressure sensor to liquid level base pressure,
Can the height change situation to liquid level be monitored and measure.In the infusion alarm system of this mode, pressure sensor installation
In infusion bag bottom, the measured value of sensor constantly reduces with the decline of liquid level.When measured value reaches the pressure size of setting
When, the liquid level of drug is also close to bag bottom, at this time by the alarm system in trigger circuit, notify medical staff replace in time drug or
Person stops injection treatment, avoids the generation of unsafe condition.
Medical pressure sensor 5 is a minute-pressure pressure sensor, while by using onboard specific integrated circuit
(ASIC) for sensor offset, sensitivity, temperature effect and it is non-linear carried out abundant calibration and temperature-compensating, it is calibrated
Pressure output value can be updated in 2kHz or so.U.S. Honeywell (Honeywell) company can be selected in medical pressure sensor 5
SSC series pressure sensor has high precision and ensures that product reliability, small size are set with internal self-diagnosis system
Also very convenient user integrates and uses meter with alternative more pressure interfaces.
Preferably, the lightshade cover is containing being protected from light transparent cover made of the medical plastic of agent up and down the two of lightshade cover
End is equipped with opening, and the bottleneck of infusion bottle stretches out lower ending opening.
Technical effect and advantage of the invention: this can be by the light proofing infusion apparatus of pressure sensitive early warning liquid level, by dripping
It struggles against and is provided with medical pressure sensor on the perfusion tube between bottle stopper penetrator, medical pressure sensor is by the liquid pressure of induction
Power is transmitted to, and on the controller on the perfusion tube of lower section inside pipe sleeve, and the both ends of pipe sleeve are respectively arranged with early-warning lamp and loudspeaker,
Loudspeaker is controlled by control button and is opened and closed, and is made under the conditions of liquid gravity, and when experiencing the deficiency of pressure, controller regulation is pre-
The unlatching of warning lamp and loudspeaker is carried out early warning in the form of light flash and audio alarm, ensure that in night or insufficient light
When, it also can timely remind patient or medical staff to warn, prevent the generation of unexpected situation, transfusion outpatient is protected to cure
Shield health, it is practical high-efficient.
