Description

Technical Field

[0001] The utility model relates to the technical field of tumor effusion extractors, in particular to a tumor effusion extractor. Background Art

[0002] Medical oncology is one of the medical specialties that studies and treats various types of tumors (cancer). Lung cancer is an important field with unique directions and expertise. Lung cancer refers to malignant tumors that occur in lung tissue, usually caused by uncontrolled cell growth and spread. It is one of the most common cancers in the world and one of the leading causes of cancer-related deaths. The main treatment directions include surgical resection, chemotherapy, radiotherapy, targeted therapy and immunotherapy. Usually, a tumor fluid extractor is needed during medical oncology treatment.

[0003] When the existing tumor effusion extractor is actually used, medical staff need to perform secondary separation when examining and testing the tissue residues in the extracted effusion, which is time-consuming and labor-intensive and inconvenient for medical staff to visually examine the tissue residues.

[0004] After searching the existing patents: a tumor fluid extractor (Announcement No.: CN215534845U), the utility model is provided with a fixing device. When the depth of the needle inserted into the patient's body needs to be fixed, the fixing device is moved left and right by loosening the rubber bolt, and the distance from the fixing device to the left end of the needle is controlled according to the millimeter scale on the needle, so as to achieve the effect of controlling the depth of the needle inserted into the body. After the needle is inserted into the body, the rubber cover is covered on the body, and the first rubber airbag is squeezed so that the first rubber airbag discharges the air in the rubber cover. The first rubber airbag is loosened so that the rubber cover is adsorbed on the body, so as to achieve the effect of fixing the position of the needle and prevent the needle from falling off.

[0005] Although the above patent achieves the effect of fixing the needle position and preventing the needle from falling off by placing the rubber cover on the body, squeezing the first rubber airbag so that the first rubber airbag discharges the air in the rubber cover, and loosening the first rubber airbag so that the rubber cover is adsorbed on the body, the tumor fluid extractor is easy to flow back after extraction during use, and it is not convenient to prevent the tumor fluid from flowing back.

[0006] Therefore, it is necessary to invent a tumor fluid extractor to solve the above problems. Utility Model Content

When in use, the protective cover is unscrewed, the drainage needle is disinfected with disinfectant cotton, the drainage needle is inserted into the patient's body, and the accumulated fluid is extracted. The accumulated fluid enters the hose and the catheter through the drainage needle and flows into the limiting cylinder. The accumulated fluid pushes open the limiting plate, so that the accumulated fluid flows into the containing cylinder. When the valve is closed, the accumulated fluid flows back, so that the limiting plate presses against the limiting ring, avoiding the accumulated fluid from flowing back into the patient's body and causing secondary infection, thereby achieving the effect of preventing the reflux of the accumulated fluid and facilitating improving the safety of the patient.
