Blood analysis system

摘要

A blood analysis system functions as a non-invasive blood parameter analyzer when a monitor is coupled with an optical sensor and as an invasive blood sample analyzer when the monitor is coupled with a blood analysis adapter. The blood analysis adapter has a transmitting assembly and a receiving assembly in electrical communications with the adapter connector so as to receive emitter signals for driving emitters within the transmitting assembly and so as to transmit a detector signal for responding to at least one detector in the receiving assembly. A cuvette containing a blood sample is irradiated with multiple wavelength light from the emitters, the detector responds to the multiple wavelength light after attenuation by the blood sample, and the monitor analyzes the blood sample according to the detector signal.

1. A blood analysis system functions as a non-invasive blood parameter analyzer when a monitor is coupled with an optical sensor and as an invasive blood sample analyzer when the monitor is coupled with a blood analysis adapter, the blood analysis system comprising:
a monitor having a sensor port and emitter drivers; the emitter drivers are in communications with a sensor port; a blood analysis adapter is removably connected to the sensor port; the blood analysis adapter has an emitter assembly and a detector; the emitter assembly transmits multiple wavelength optical radiation to a blood sample inserted into the blood analysis adapter in response to the emitter drivers; a blood modulator that modulates the blood sample so as to simulate pulsatile blood; the detector is responsive to the optical radiation after attenuation by the blood sample; and the detector response is communicated to the monitor for analysis of the blood sample.
