The former is mainly used for the purpose of promptly knowing abnormal conditions caused by surgical operations such as postoperative suture failure, and a hollow container or bag is inserted into the wound cavity with a catheter for inducing exudate discharge. A shape container is connected. On the other hand, the latter is created for the purpose of preventing infection when postoperative bleeding, gastrointestinal fluid, exudate, etc. are pooled or when pooling is expected, or for the purpose of inducing abscess or hematoma pooled due to trauma. The exudate in the wound cavity is accumulated and stored in the suction collector due to the negative pressure generated in the suction collector, inserted into the cavity and connected to the suction collector.

  There are various mechanisms for generating negative pressure in the suction collector. First of all, an elastic container or a flexible container with a built-in spring, or the container itself is bellows. The one using the action (see, for example, Patent Document 1), the second using the action of contracting the balloon member that can be expanded and contracted in the rigid container, and the third, the gasket for holding the airtightness in the rigid container. The thing using the effect | action by expanding a volume by sliding from the zero state is used.

  If the natural drainage method is tried but the drainage effect is not obtained, for example, when the viscosity of the drainage liquid is high, it may be necessary to switch to catheter milking operation or continuous suction. Immediately after the operation, suction and drainage is performed by a suction collector. However, if aggressive suction and drainage is performed, the exudate may not stop forever and healing may be delayed. It may become. In this case, a procedure for removing the catheter from the suction collector and a procedure for attaching the catheter to a new collection container are required, and the procedure is troublesome and of course there is a risk of infection.
