Abstract
The utility model discloses a kind of disposable measurement biochip of blood gaseous analysis, comprise chip body, described chip body is provided with sample chamber, partial pressure of carbon dioxide sensing chamber, potential of hydrogen sensing chamber and partial pressure of oxygen sensing chamber, described sample chamber is provided with injection port, the end of described chip body is provided with female Luer, described sample chamber is connected with partial pressure of carbon dioxide sensing chamber, described partial pressure of carbon dioxide sensing chamber, is connected by sensing membrane successively between potential of hydrogen sensing chamber and partial pressure of oxygen sensing chamber.The disposable measurement biochip of this blood gaseous analysis, very convenient when carrying out gas and pH measurement to blood, improve speed and the accuracy of blood being carried out to gas and pH measurement greatly, ensure that the accuracy that some pathological condition are diagnosed.
Description
Technical field
The utility model relates to blood gas analysis biochip technology field, is specially a kind of disposable measurement biochip of blood gaseous analysis.
Background technology
As everyone knows, multiple pathological condition can be identified by the gas existed in analyzing blood.Be generally used for these technology analyzed to need to extract blood sample by various method, and store these samples in environment subsequently under the conditions such as isolation, constant temperature, then carry out the analysis of blood.
PCO2, PO2 electrode calibration of existing domestic blood gas analyser all adopts the different high gas of gas mixing ratio and low gas two kinds of pressure gass iontophoresis electrode Measurement channel after decompression, insulation, humidifying to calibrate, and remaining electrode adopts normal fluid calibration.In this calibration mode, stream divides gas circuit and fluid path, gas-liquid infall controls comparatively complicated, particularly in case of a failure, calibration solution or cleaning fluid enter gas circuit and very easily damage solenoid valve, in addition, due to the existence of gas cylinder, instrument is not easy to make the portable of removable use or hand propelled, makes Standard Gases transport inconvenience; Because calibrating gas is pressure gas, gas cylinder is comparatively large again, is not easy to transport and uses, and pressure gas is just available after decompression, insulation, humidifying, and use procedure is comparatively loaded down with trivial details, operation more complicated.Therefore for solving the trouble that general measure instrument uses, a kind of easy to use and blood gas analyser of reliable in quality is just needed.
Utility model content
The purpose of this utility model is the disposable measurement biochip providing a kind of blood gaseous analysis, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of disposable measurement biochip of blood gaseous analysis, comprise chip body, described chip body is provided with sample chamber, partial pressure of carbon dioxide sensing chamber, potential of hydrogen sensing chamber and partial pressure of oxygen sensing chamber, described sample chamber is provided with injection port, the end of described chip body is provided with female Luer, described sample chamber is connected with partial pressure of carbon dioxide sensing chamber, described partial pressure of carbon dioxide sensing chamber, is connected by sensing membrane successively between potential of hydrogen sensing chamber and partial pressure of oxygen sensing chamber.
Preferably, described female Luer is set to two, and two female Luer are symmetric the two ends being arranged on chip body.
Compared with prior art, the beneficial effects of the utility model are: the disposable measurement biochip of this blood gaseous analysis, reasonable in design and simple to operate, very convenient when carrying out gas and pH measurement to blood, improve the speed of blood being carried out to gas and pH measurement greatly, sensing membrane makes chip to the gas of blood and pH measurement efficiency is higher and accuracy is better, female Luer improve to blood gas and pH measurement data transmission stability and accuracy, ensure that the accuracy that some pathological condition are diagnosed.
