Description

Rear end cover sealing waterproof structure of microcirculation imaging device Technical Field The invention relates to the technical field of medical instruments, in particular to a rear end cover sealing waterproof structure of a microcirculation imaging device. Background The blood circulation between the micro-artery and the micro-vein in the human body is called micro-circulation, which is the most basic unit of the blood circulation of the human body and is the place where the blood and the tissue exchange substances, the blood flow of the micro-circulation directly reflects the metabolism condition of the human organ, and if the micro-circulation of the human body is blocked, the physiological functions of the tissue organ can be greatly affected. That is, disorders of the human microcirculation often indicate signs of some diseases. For example, the state of microcirculation changes greatly when immune diseases, cardiovascular and cerebrovascular diseases, burns, pulmonary edema, shock and the like occur, so that the monitoring and observation of human microcirculation has great clinical significance for medical staff. The microcirculation imaging device is a novel photoelectric instrument, is mainly used for human body microcirculation inspection, is widely used for early diagnosis, disease forecast, curative effect judgment, prognosis estimation and the like of microcirculation change of various diseases (such as cardiovascular and cerebrovascular diseases, hypertension, apoplexy, diabetes mellitus, rheumatic arthritis and the like, especially the disease change prevention of critical patients) because of no wound and no side effect, and provides diagnosis and treatment basis for clinic. However, the problem of poor sealing performance exists at two ends of the shell of the existing microcirculation imaging device, and liquid easily enters the shell from a gap in the use process or during daily cleaning and disinfection to damage an internal circuit, so that the microcirculation imaging device with good waterproof performance and convenient disassembly and assembly is required to be provided.
