Problems solved by technology

[0007] At present, the contact surface between artificial organs and blood is mainly processed or coated with anticoagulant materials, which not only increases the manufacturing cost and difficulty of the organ, but also cannot fully play the anticoagulant function. Once coagulation occurs, Only when it is more serious can it be reflected through clinical manifestations, often causing great pain and serious consequences to the patient

Embodiment Construction

[0032] At present, the contact surface between artificial organs and blood is mainly processed or coated with anticoagulant materials, which not only increases the manufacturing cost and difficulty of the organ, but also cannot fully play the anticoagulant function. Once coagulation occurs, Only when it is more serious can it be reflected through clinical manifestations, which often causes great pain and serious consequences to the patient.

[0033] Aiming at the deficiencies in the prior art, the invention provides a device and a detection method for detecting blood coagulation on the surface of an artificial organ. By setting capacitive sensors, it is possible to more accurately determine the location of specific blood coagulation, better judge the occurrence of blood coagulation, and timely and accurately feed back information to doctors, which can control diseases caused by blood coagulation or thrombus in the "upstream" stage of disease occurrence, Early judgment and dete...

Abstract

The invention discloses a device for artificial organ surface blood coagulation detection. Capacitive sensors are arranged on an artificial organ, a non-physical contact detection mode is adopted, the blood coagulation area is detected through the edge effect between every two adjacent capacitive sensors, an electrostatic field is generated between two pole plates of a capacitor, whether blood coagulation happens or not or whether blood concentration of the blood coagulation area suddenly changes or not is judged according to changes of the capacitance, and early judgment and blood coagulation detection are achieved. The capacitive sensors are fixed in an array mode, the specific blood coagulation position can be more accurately judged, the blood coagulation situation can be better judged, and information is accurately fed back to a doctor in time. By the adoption of the MEMS capacitive sensors, microminiaturization and high integration level of the sensors can be achieved, the high density of the array of the sensors can be achieved, and meanwhile, the micro sensors are simple in structure. Due to the non-physical contact detection, and due to the fact that the capacitive sensors are arranged on the lower side of an anticoagulation coating, the reliability of the capacitive sensors is improved, and the service life of the capacitive sensors is prolonged.

Description

technical field [0001] The invention belongs to the technical field of medical detection equipment, and in particular relates to a device and a detection method for detecting blood coagulation on the surface of an artificial organ. Background technique [0002] Artificial organs are artificial devices that temporarily or permanently replace the main functions of certain organs of the body. The most widely used ones are: ①Artificial lung (oxygenator) is a device that simulates lungs for exchanging O2 and CO2. The oxygenator oxygenates venous blood with low oxygen content in the body into arterial blood with high oxygen content. ②Artificial heart (blood pump). A device that replaces the heart's blood pumping function, similar in structure to a pump, can drive blood flow to overcome resistance and flow in one direction. The artificial heart and artificial lung are collectively called the artificial heart-lung machine, which was first used on the human body in 1953 and is main...
