Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a drainage device for breast surgery. Background Art

[0002] The mammary gland is an important physiological structure of women. As an accessory gland of the skin, it is composed of glands, fibrous tissue, fat cells and nerve cells. Breast diseases involve inflammation, benign lesions, malignant tumors, etc., which need to be prevented through a reasonable diet, proper exercise, regular check-ups, etc.

[0003] Fluid effusion after breast surgery is a common complication. The causes may include intraoperative injury, postoperative infection, intrathoracic bleeding and other factors. The harm of fluid effusion after breast surgery cannot be ignored. It may cause chest pain, swelling, fever, infection and other symptoms. In order to deal with these effusions and avoid affecting postoperative recovery, doctors often use puncture drainage to remove the fluid in the breast with negative pressure suction.

[0004] However, existing hospital drainage devices have deficiencies in connection and fixation. The connection between the drainage tube and the patient's body is often not stable enough and is prone to move or fall off during the drainage process, resulting in poor drainage or treatment failure. In addition, traditional drainage devices also have limitations in adjusting negative pressure. The adjustment of negative pressure is crucial to the efficiency and safety of the drainage process, but traditional drainage devices are often unable to accurately control the size of the negative pressure, resulting in unstable drainage speed and flow, and may even cause unnecessary harm to the patient. In order to solve the above problems, while facilitating the fixation of the drainage tube on the patient, the negative pressure can be adjusted according to the patient's drainage needs, thereby adjusting the drainage speed and flow, which is more convenient for use in fluid drainage. For this reason, we propose a drainage device for breast surgery. Utility Model Content

[0034] Instructions

[0035] When in use, first thread the drainage tube 4 into the connection port 3 fixedly installed at the bottom of the fluid accumulation bag 1, then fix the other group of connection ports 3 on the top of the fluid accumulation bag 1 to the bottom of the negative pressure bag 2, and then according to the incision, place the diversion end ball 6 fixedly installed at the end of the drainage tube 4 into the fluid accumulation in the patient's body. After the position is determined, the limiting piece 7 can be slid and installed on the outer wall surface of the drainage tube 4 to fit it with the incision, and then the limiting piece 7 can be fixed to the drainage tube 4 through the cooperation between the fixing seat 8 and the screw, and then the adhesive strips at the bottom of the medical tape 9 fixed on both sides of the limiting piece 7 can be torn off, and then the medical tape 9 can be attached to the patient's skin surface, and the drainage tube 4 and the limiting piece 7 can be repaired. The bag 1 and the negative pressure bag 2 are fixed to prevent the diversion end ball 6 from moving or falling off due to the patient's movements during use.
