Double-drainage device for oncology department

Abstract

The invention discloses a double-drainage device for the oncology department, and the double-drainage device comprises a negative pressure power mechanism, a collection assembly, a negative pressure suction assembly and a control mechanism, the negative pressure power mechanism is provided with a first main electromagnetic gas valve and a main pressure sensor which are used for controlling the main gas pipe, and is provided with a first auxiliary electromagnetic gas valve and an auxiliary pressure sensor which are used for controlling the auxiliary gas pipe; through the cooperation of the negative pressure power mechanism, the collecting assembly and the negative pressure suction assembly, rapid separation type drainage of effusion and tissue blocks is achieved, the occurrence of the blocking phenomenon is greatly reduced, and the workload of medical staff is reduced; the negative pressure suction assembly is compact in overall structure through the main hose and the auxiliary hose which are arranged in a sleeved mode, long-distance effusion suction in the tissue block drainage process is achieved, and the separation effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a double drainage device used in an oncology department. Background technique [0002] The medical drainage device is a commonly used medical device during the operation. Its main function is to absorb the exudate, pleural effusion, pus and the contents of the abdominal organs produced during the operation, so as to ensure the clarity of the operation and reduce the probability of mutual contamination. . For example, Chinese Patent Publication No. CN113730673A discloses a drainage device for medical oncology, which mainly solves the problem of treating effusion during treatment. The device can also be used to prevent effusion formation and lymphatic drainage after surgery, such as after radical tumor resection, where drainage needs to be placed on the chest wall and axilla in order to prevent subcutaneous effusion and lymphatic leakage and other complicatio...

AI Technical Summary

Problems solved by technology

The existing negative pressure bottles used for drainage devices after tumor surgery can basically only provide negative pressure for a certain period of time. The drainage effect is very good at the initial stage, but as the drainage time prolongs, the negative pressure in the negative pressure bottle gradually decreases Unstable, the suction of drainage is getting smaller and smaller, or even stops drainage, which requires medical staff to perform frequent pressure relief operations, wasting time and energy, and the drainage effect is not good

In addition, the current drainage devices drain the tissue block and effusion together, which is prone to blockage and increases the workload of medical staff. If the tissue block and effusion need to be separated, secondary treatment is required. Increase the probability of sample contamination and affect judgment
