Technical Field
The invention belongs to the technical field of medical drainage devices, and particularly relates to a postoperative drainage device for breast cancer.
Background
At present, the incidence rate of breast cancer is high, breast is not an important organ for maintaining vital activity of human body, in-situ breast cancer is not fatal, but because breast cancer cells lose the characteristics of normal cells, the connection among cells is loose and easy to fall off, and once cancer cells fall off, free cancer cells can spread on the whole body along with blood or lymph fluid to form metastasis, thus endangering life. At present, the operation modes of breast cancer adopted in China mainly comprise classical radical operation, improved radical operation, enlarged radical operation, simple mastectomy, mastectomy and the like, and the radical operation of breast cancer is a common surgical treatment means adopted for breast cancer patients and is also a preferred treatment scheme for the breast cancer patients. The radical surgery is to resect the whole diseased breast together with 5cm wide skin around the tumor, fat tissue around the breast, the pectoral and myogenic muscle and fascia thereof, all fat tissue under armpit and collarbone and lymph node, drain the residual fluid generated under the endothelial valve in the operation range during the recovery period after radical surgery of the breast cancer.
The drainage device that exists on the market at present is through settling the drainage tube in wound position to carry out waste liquid drainage with negative pressure device at end-to-end connection drainage bottle, fix the drainage tube through the fixer during, in order to avoid body overlength winding patient or extension drainage rate, but current drainage device is usually not good to the fixed effect of drainage tube, leads to the drainage tube drunkenness to influence the drainage effect of drainage tube, and when end drainage bottle storage capacity upper limit or drainage tube are pressed, liquid backward flow easily and be difficult for finding, not only can influence drainage speed, still probably infects the wound.
U.S. patent application No. US18087165 discloses a method of cancer treatment, the invention comprising a dual port flow diverter comprising a reservoir for collecting a liquid and a first port for diverting a fluid and a second port for delivering a therapeutic agent, the dual port flow diverter comprising an assay device for biomarker detection. The first port includes a first valve body for sealing the first port, the first valve body for preventing the first port from collecting the expelled fluid, and the second port includes a second valve body for sealing the second port from delivering the therapeutic agent into the port. At the end of the delivery, the second port is closed by the second valve body, and the first port is closed by the first valve body, and the first port is connected with a sample filter for capturing solid particles and a heat source for adjusting the temperature of the collected liquid. The invention facilitates the preservation of the biomarkers in the collection fluid through a plurality of reservoirs and maintains them within a suitable temperature range to avoid degradation of the nucleic acids. However, the whole device is too complex, when the conditions of blockage, backflow, pipe leakage and the like occur, the device is difficult to adjust and maintain in time, and the drainage device is inconvenient to adjust along with the actions of personnel, so that the problem of inconvenient movement is brought to a patient.
