Description
Technical field
The present invention relates to the heating apparatus and its application method for being transfused or rinsing, it is specifically for use in medical transfusion, defeated
Blood and clinical flushing.
Background technique
Infusion and flushing are important clinical treatment means, especially largely rinse in infusion medical fluid, blood and operation, real
The infusion flushing liquor in medical fluid and operation often room temperature or cryo-conservation when border uses, most blood are also that freezer is protected
It deposits, since input fluid temperature is low, a large amount of inputs will lead to hypothermia, very big harm is brought to patient, such as surgery cut infection,
Cardia cevent, coagulation function decline, recovery from anesthesia time extend, extended hospital stay etc., therefore in infusion process
It needs to liquid warming.Therefore, carrying out heating in infusion is common clinical supplementary means, and the flushing in operation also has and makes
With, but often because it is pressed for time, utilization rate is not high.
Current clinically common heating means have heating water bath, incubator heating, perfusion tube heating etc..Heating water bath may
Germ is taken to pipeline surface by water-bath, may carry extremely purification region, purifying garment or net after medical staff or sufferer contact
Change on gloves, it is easy to which cross-infection is given the patient for having wound or propagated at other sufferers by mucous membrane contact, is institute's inner sense
The potential source of dye.
Incubator heating is one of the heating method generally used, needs in advance to be placed into incubator liquid and heat up, and is heated
Speed is slow, time-consuming, is not suitable for promptly being infused or transfusing blood；For heated liquid temperature without accurate display, temperature control is inaccurate；It is quiet
Only liquid heats, and heating is uneven, may cause physical and chemical properties of drugs change；Heat insulation effect is poor, heat leakage in infusion process
More, infusion process is often cool after elder generation is hot；Heating speed is restricted by liquid initial temperature, and initial temperature is lower, is heated slower.
Perfusion tube heating is also the mode being commonly used, the perfusion tube heating of patent No. ZL 200420036761.4
Mainly by the way that pipeline is placed in heating device, this way pipeline heating surface area is very limited, and usually liquid does not heat also in pipeline
Flowed to downstream to temperature, therefore on this problem, way be directly to be placed in bag body in heating apparatus, or adding
Very high temperature is set to achieve the purpose that quickly to heat, such as patent No. in thermal: ZL 03241419.6, but also therefore
Plastic packing article or pipeline are produced by high temperature melt or the security risk of precipitation chemical substance.There are also be coiled in using by pipeline
Increase the solution of heating surface area inside heating device, such as patent No.: ZL 201520889903.X, the patent No.: ZL
201730673014.4, number of patent application: ZL 201830317017.9, this way increase really heating surface area but also because
This makes pipeline become considerably long, and too long pipeline is very easy to kink or hangs rub other articles, Er Qie in use
Coiling pipeline is required when using every time, it is very inconvenient, and above two solution exists because of extrusion infusing pipeline itself
Specific thicknesses, caused by it is thermally conductive slow, using effect is bad.And equipment is often all bigger, carries not flexible installation
It is troublesome, be not easy to using.

It is promptly warmed to comfort temperature entirely, helps to maintain patient temperature, prevents hypothermia to adverse effect caused by patient, and
Avoid heating temperature it is excessively high, it is too low or when it is high when it is low.
Heating apparatus uses the circuit design of heating power capable of automatic changing, can voluntarily adjust after reaching preset temperature
Heating power keeps target temperature, and the material of liquid container will not be made to melt or be precipitated chemical substance, heating dress because temperature is excessively high
Be equipped with auto-alarm function, so as to caused by because of power-off, misoperation or other reasons shut down etc. unexpected situations when and
When obtain warning make correspondence.Upper heating sheet is tightly attached on heat-conducting plate, and lower heating sheet is tightly attached on lower heat-conducting plate, in favor of equal
It is even that efficiently liquid is heated.Solid-state relay has input power small, high sensitivity, and control power is small, electromagnetic compatibility
Property good, the features such as noise is low and working frequency is high.Microcontroller has function abundant and Peripheral Interface, has saved external device
Part.
2.7 cun of OLED screens of display portion, temperature range is wide, and visible angle is greater than 160 °, and display font is big and clear,
Also there is good visual effect under not good enough illumination condition.The ac-dc conversion part of power circuit has global input voltage
The advantages that range, AC and DC, low-power consumption, high efficiency, high reliability, security isolation.It is arranged in two of line style opening
Outlet can be convenient user and liquid container be inserted into position, and be easily found impetus when taking out.The design of handle can be with
Allow user that selectively machine to be mounted on Medical rack bar or is directly placed in plane support, two ways is not
Influence using effect.Handle then can allow user more easily to move and put heating apparatus, mitigate the work of medical staff
Burden is also avoided that in mobile collide with etc. caused by machine breakdown.
