Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a venous thrombosis monitoring device and system. Background Art

[0002] Venous thromboembolism (VTE) refers to a group of diseases including deep vein thrombosis and pulmonary thromboembolism. It is the third largest vascular disease after myocardial infarction and stroke. It has an insidious onset, atypical clinical symptoms, and is easily misdiagnosed or missed. It has a high mortality and disability rate and is one of the important causes of unexpected death and perioperative death in hospitals. Medical staff need to measure and monitor the leg circumference of patients' lower limbs every day, judge the patient's condition by the changes in leg circumference, and take corresponding nursing measures. Therefore, early detection and monitoring of venous thrombosis are crucial to prevent these complications.

[0003] At present, there are some methods and technologies for detecting and monitoring venous thrombosis. In the traditional method, some leg circumference measuring rulers are used. Medical staff use measuring rulers to measure the measurement positions according to the positioning points, and then use the measuring ruler to measure the corresponding positions around the patient's legs. This method can only roughly determine the measurement points, and the manual measurement information is low in work efficiency and easily causes measurement position deviation. There is also a leg circumference measuring device in the prior art, which fixes the patient's lower limbs through a foot pedal, and uses the positioning points to determine the position of the measurement ring of the thigh and calf, and then uses infrared to measure the leg circumference where the measurement ring is located. This measuring ruler improves the measurement efficiency and measurement accuracy to a certain extent, but this device adjusts and fixes the measurement ring on the patient's limb part through an air bag and an air pump. The device is complex, the measurement ring size is single and it is a closed loop, and the patient needs to put it on and take it off from the foot, which is inconvenient to wear and limited in use; on the other hand, this device can only measure the leg circumference, and cannot obtain the thrombus image information of the patient's leg; this device only fixes the size of the measurement ring on one side, and there is a situation where the measurement ring is tilted and the sizes of the two sides are inconsistent, resulting in inaccurate measurement results.

[0004] There is no effective solution to the problems existing in the related technology, such as complex measurement structure, single measurement ring size, inconvenient wearing and limited use, inability to observe limb thrombosis in patients, tilted measurement ring, inaccurate measurement results, etc. Utility Model Content
