Description

Technical Field

[0001] The invention relates to the technical field of high-pressure oxygen spraying, in particular to a device for monitoring limb lymphedema after malignant tumor surgery. Background Art

[0002] The most common and serious complication after breast cancer surgery is lymphedema of the affected limb. Once it occurs, it cannot be cured and has a high disability rate. However, the occurrence of lymphedema is a slow cumulative process and patients often do not easily notice it. As time goes by, the patient's role behavior declines and they will unconsciously use the affected limb to lift heavy objects, leading to or aggravating the occurrence of lymphedema. If the patient is not monitored, prevented and reminded to detect lymphedema in time, it will be detrimental to the patient's postoperative limb recovery, causing limb pain and inability to take care of themselves, which will seriously affect the quality of life. The traditional monitoring method is to measure the circumference of the limbs multiple times with a tape measure, record and calculate the subsequent swelling size multiple times, and then calculate the degree of danger through scientific calculation methods. Alternatively, the patient presses the skin and observes the skin's rebound speed to determine whether they have edema. Therefore, there are efficiency issues such as the need for repeated calculations and uncertainty about the specific rebound time, making it impossible to quickly and accurately determine whether you have edema.

[0003] In view of the above problems, a device for monitoring limb lymphedema after malignant tumor surgery is proposed. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a postoperative limb lymphedema monitoring device for malignant tumors. When in use, the scale bar is located at the zero position in the scale groove. The monitoring ring is brought into contact with the limb by adjusting the position of the positioning bar in the positioning groove, the circumference is determined and the positioning bolt is fixed. When edema occurs, the limb will swell, and then the scale bar will slide, thereby increasing the circumference of the monitoring ring. The degree of swelling of the limb can be directly seen by observing the moving distance of the scale block in the scale groove.

[0013] 2. The present invention provides a device for monitoring limb lymphedema after malignant tumor surgery. The pressing piece is driven to move by a telescopic rod to squeeze the skin.
