Abstract
The present invention relates to a kind of cardiopulmonary circulation blood pump injury of blood cell monitoring device, including piping material, real-time monitoring modular, message handler, signal projector, the monitoring modular in real time includes laser, light-passing board, photodiode, data acquisition unit, light-passing board interlayer flows through the blood sent out by blood pump, institute's laser illumination light-passing board interlayer, the haemocyte projected area signal as caused by receiving photodiode, and input data collector, transmitted by data acquisition unit to message handler, message handler is classified to data, when data over range, enabling signal transmitter sends alarm.The present apparatus can detect the destruction of hydrodynamic factor that various types of blood pumps continuously flow to red blood cell in real time, and be alarmed when outside blood solubility prediction data will go beyond the scope.And real time implementation is realized, and digitize, it is intelligent while portable and easy to operation, reliable accurate data are provided for detection, the detection to injury of blood cell caused by blood pump is significant.
Description
Technical field
The present invention relates to a kind of cellular damage monitoring device, especially a kind of cardiopulmonary circulation blood pump injury of blood cell monitoring dress
Put, belong to cellular damage monitoring technical field.
Background technology
Hydrodynamic factor, structure etc. have Latent destruction effect to haemocyte when blood pump device continuously circulates（Haemolysis）, can
Cause heart failure, acute renal failure severe patient even dead.Haemolysis is also to evaluate injury of blood cell caused by blood pump most
For one of important parameter, should monitor in real time to reduce the potential safety hazard using patient to extracorporeal circulation equipment.And Chinese phase
Not yet hemolysis evaluation is included in the index of evaluation blood pump potential risk in the blood pump standard of pass, it is hidden to leave safety to use
Suffer from.BiologicalEvaluationofMedicalDevice Part IV：Also without reference to blood pump device in " blood interaction experiment selection ".China
Cardiopulmonary circulation blood pump injury of blood cell evaluation criterion is currently establishing, is badly in need of developing the detection device related to this standard.
The content of the invention
Hydrodynamic factor, structure etc. exist to haemocyte when the technical problem to be solved in the present invention is the circulation of blood pump device
Latent destruction is acted on, and can not but monitor in real time, and patient is known nothing danger, and provides a kind of cardiopulmonary circulation blood pump haemocyte damage
Hinder monitoring device.
In order to solve the above technical problems, technical scheme：A kind of cardiopulmonary circulation blood pump injury of blood cell monitoring dress
Put, including piping material, real-time monitoring modular, message handler, signal projector, the monitoring modular in real time include laser
Device, light-passing board, photodiode, data acquisition unit, the light-passing board interlayer flow through the blood sent out by blood pump, the laser
Device irradiates light-passing board interlayer, the haemocyte projected area signal as caused by receiving photodiode, and input data collector, by
Data acquisition unit to be transmitted after data signal to message handler, classifies electroporation by message handler to data, when
Enabling signal transmitter sends alarm during data over range.
Temperature that the data acquisition unit collects, pressure, blood solubility data change into data-signal output and pass through signal
Transmitter, transmission, which is expanded on extraneous hardware device, to be shown, accomplishes to monitor indices in real time.
Data are classified with c language for described information processor and calculating processing.
The light-passing board have can hold the small interlayer that red blood cell flows through.
Beneficial effects of the present invention：
The real-time monitoring temperature of device of the present invention, pressure, many index such as blood solubility, and can will be defeated outside data, ensure patient
To the cognition degree of equipment.Blood solubility can send alarm when exceeded, reduce the potential safety hazard using patient to extracorporeal circulation equipment.
Digitlization is realized, it is intelligent while portable and easy to operation, it is execution and the extracorporeal circulation equipment haemocyte damage of national new standard
The detection of wound provides reliable accurate data.
Brief description of the drawings
Fig. 1 is the structural representation of the cardiopulmonary circulation blood pump injury of blood cell monitoring device of the present invention；
Fig. 2 is real-time monitoring modular structured flowchart.
Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is made into a detailed description.Following examples
For illustrating the present invention, but it is not limited to the scope of the present invention.
Such as Fig. 1, shown in 2, cardiopulmonary of the invention circulation blood pump injury of blood cell monitoring device, including piping material, in real time
Monitoring modular, message handler, signal projector.Cardiopulmonary flow system（Blood pump）During normal operation, the present apparatus is entered as collateral branch
Row monitoring.Power supply gives laser continued power, thin to blood in being produced on photodiode when blood is flowed through in light-passing board interlayer
The projection of born of the same parents.During projected area difference, photodiode produces different size of electric pulse, is turned electric pulse by data acquisition unit
Transmitted after turning to data signal to message handler.Message handler is classified using c Programming with Pascal Language to data, and data are beyond specified
Enabling signal transmitter sends alarm during scope.
This monitoring device can by temperature that data acquisition unit collects, pressure, that blood solubility data change into data-signal is defeated
Go out by signal projector, shown on extraneous hardware device, accomplish to monitor indices in real time.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and modification can also be made, these improve and become
Type also should be regarded as protection scope of the present invention.
