Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for introducing a coagulant into a waste fluid collection container for aspirating and storing body fluids such as blood generated during surgery or treatment and washing fluid.

[0002]

2. Description of the Related Art It is rare that harmful liquids such as harmful bacteria are contained in the liquid waste aspirated into the liquid waste collection container, and the harmful liquid bacteria are being handled in order to prevent secondary infection due to this liquid waste. Currently, a method of treating the waste liquid with a coagulant for the purpose of preventing the dispersion of the waste liquid and the spillage of the waste liquid is generally performed, and various methods of adding the coagulant have been studied.

For example, in Japanese Patent Laid-Open No. 4-60713, (1) a coagulant container in which a coagulant is collected is provided on the upper part of a collection container, and means for charging the waste liquid is provided (2).
A form has been proposed in which the coagulant is placed in the collection container in advance. As for this problem, in the above (1), the lid of the collection container is complicated and its manufacture becomes difficult. Since the volume and weight of the lid portion increase, the center of gravity becomes high and the stability becomes poor. The work of containing the coagulant inside is also difficult, and means must be provided to keep the coagulant inside the lid before it solidifies. In the case of (2), since the waste liquid contacts the coagulant immediately after entering the collection container and coagulates, the condition of the patient from the waste liquid cannot be confirmed, and the performance of the coagulant in a wide space for a long period of time may change. When the coagulant is a powder, it is necessary to consider that the powder does not leak to the outside and does not move to the dead space inside the collection container.

In order to solve these problems, Japanese Patent Laid-Open No. 6-254124 discloses that a coagulant container is later attached to an opening of a waste liquid introducing port or an exhaust port of a lid of a waste liquid collecting container, or a coagulant A means has been proposed in which an opening for attachment is provided and sealed with a lid, and when the coagulant container is attached, the lid is removed and the coagulant container is used as it is.

When the waste liquid introducing port or the exhaust port of this method is used, the internal diameter of this opening is related to the connecting tube, and it is difficult to make the internal diameter large. Therefore, the input port of the coagulant container cannot be large. become. For this reason, it is good to use the waste liquid collection container alone, but when using several connected waste containers, the parts other than the final exhaust port may be wet with the waste liquid. When the coagulant container is connected to this opening, it is assumed that the coagulant acts at the tip of the coagulant container to make it difficult for the coagulant to enter.

Even after the coagulant container is connected and the coagulant is charged and coagulated, the waste liquid introduction port or the exhaust port is in an open state, so that there is no problem if the drainage liquid is hard and coagulated.
If the waste liquid is solidified in a jelly state or if some waste liquid that cannot be solidified remains, it may leak from this opening depending on the storage condition of the waste liquid collection container. Therefore, it is necessary to attach a cap to this opening for sealing, and the cap must be installed somewhere.

The case where a coagulant mounting port is newly provided is that the cap of the coagulant mounting part is removed and an opening is provided to mount the coagulant container.
Considering that the waste liquid is coagulated with a coagulant for the purpose of preventing scattering and spillage during handling to prevent secondary infection due to the waste liquid, the opening that may come into contact with the waste liquid should be considered. There was a problem that it would be increased before the coagulation treatment.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to allow a coagulant to be introduced smoothly and at the same time minimize the possibility of contact with a waste liquid, so that the coagulated waste liquid leaks from the collection container to the outside. The present invention provides a waste liquid treatment container and a method for adding a coagulant to a waste liquid collection container.

[0009]

SUMMARY OF THE INVENTION The present invention provides a method for coagulating a waste liquid stored by suction in a waste liquid collecting container having a waste liquid inlet and an exhaust port for sucking the waste liquid in the upper part. By attaching the coagulant container to the coagulant mounting part on the lid of the waste liquid collection container, the coagulant mounting part of the waste liquid collection container opens, the coagulant is thrown into the waste liquid collection container, and the coagulant container remains open. It is a method for charging a coagulant into a waste liquid treatment container, which is characterized in that a portion is sealed.
