Abstract

A cartridge for an apparatus for analyzing blood chemistry includes an apparatus frame having a compartment; a cartridge that is inserted into the compartment of the apparatus frame and includes a sensor card, a solution valve unit, and a blood introducing unit; a controller that receives a signal generated from the sensor card and processes the signal; a lever for the blood introducing unit connected to the apparatus frame; a power transmitting unit that is provided to the apparatus frame and transmits power of the lever for the blood introducing unit to open/close the blood introducing unit of the cartridge; a solution transporting unit that is provided to the apparatus frame and transports the solutions; and a driving unit that actuates the solution valve unit of the cartridge by the controller and opens or closes the tubing flowing of the solutions.

Claims

1. An apparatus for analyzing blood chemistry, comprising:

an apparatus frame having a compartment;

a cartridge that is inserted into the compartment of the apparatus frame and includes solution bags that contain solutions, a solution valve unit that allows or blocks the flow of the solution, and a blood introducing unit;

a sensor card that is disposed in the cartridge or in the apparatus frame and measures the concentrations of electrolytes, the partial pressures of gases, the concentrations of metabolites, or the volume ratio of the red blood cells contained in blood supplied through the blood introducing unit;

a controller that receives signals generated from the sensor card and processes the signals;

a lever for the blood introducing unit that is fastened by a hinge to the apparatus frame such that the lever for the blood introducing unit rotates about a hinge shaft;

a power transmitting unit that is provided at the apparatus frame and that opens or closes the blood introducing unit using torque due to an operation of the lever for the blood introducing unit;

a solution transporting unit that is provided at the apparatus frame and transports the solutions in the solution bags; and

a driving unit;

wherein each driving unit includes

a solenoid unit that is controlled by the controller; and

a movable member that moves based on electrical operation of the solenoid unit and that actuates the solution valve unit of the cartridge, the movable member opening or closing a tubing to flow of the solutions;

wherein the apparatus frame includes a cartridge door having a cartridge door lock that locks the cartridge door to the apparatus frame and a cartridge door lock sensor that senses a locking status of the cartridge door; and

wherein the apparatus frame includes a lever lock that locks the lever for the blood introducing unit and a lever lock sensor that senses a locking status of the lever.

2. The apparatus for analyzing blood chemistry of claim 1, further comprising

data output units that output data processed by the controller,

wherein the data output units include a display and a printer, both of which are integrated in the apparatus.

3. The apparatus for analyzing blood chemistry of claim 1, wherein a part of the controller that receives signals generated from the sensor card and processes the signals is electrically isolated from a part of the controller that controls the solution transporting unit and the driving unit.

4. The apparatus for analyzing blood chemistry of claim 1, wherein the signals generated from the sensor card that the controller receives and processes are electrically isolated between the signals depending on the type of the signals.

5. The apparatus for analyzing blood chemistry of claim 1, wherein the cartridge door is fastened by a hinge to the apparatus frame and the cartridge door lock sensor senses the locking status of the door lock and transmits a sensed signal to the controller.

6. The apparatus for analyzing blood chemistry of claim 1, wherein the lever lock locks the lever for the blood introducing unit and a sensing unit senses the locking status of the lever lock and transmits a sensed signal to the controller.

7. The apparatus for analyzing blood chemistry of claim 1, wherein the apparatus frame is provided with a sensing unit that detects the operation of the driving unit and transmits a detected signal to the controller.

8. The apparatus for analyzing blood chemistry of claim 1, wherein the lever for the blood introducing unit is the cover for the blood introducing unit that is composed of a magnifier at the center thereof.

9. The apparatus for analyzing blood chemistry of claim 1, wherein the apparatus frame is provided with a heater block equipped with a heater to maintain the temperature of the sensor card constant.

10. The apparatus for analyzing blood chemistry of claim 1, wherein the cartridge is provided with a waste container that is connected with the sensor card through tubing.
