Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to various body fluids collected from patients, etc., as well as washing water containing chemicals such as body fluids, chemicals, urination and other liquid or gel-like substances that cannot be discarded into general sewage ( (Hereinafter referred to as "waste liquid"), the present invention relates to a waste liquid collecting device used when collecting for various inspections or disposal, and a waste liquid treating method using the waste liquid collecting device.

[0002]

2. Description of the Related Art The present applicant has already developed and applied a waste liquid recovery device capable of easily and quickly disposing of waste liquid and capable of almost completely eliminating the risk of infection or the like through the waste liquid. (See Japanese Utility Model Laid-Open No. 4-37585). The waste liquid recovery device according to this prior application is provided with a transparent waste liquid storage device, a lid provided on the waste liquid storage device having a storage portion for the coagulant, and an opening on the lower surface of the lid. It is composed of an inner plug that closes the spray port of the storage unit, and an operation unit that can remove the inner plug from the spray port by an external operation. The lid is provided with a waste liquid injection pipe and an intake pipe that communicate with the inside of the waste liquid reservoir, and the waste liquid injection pipe is connected to a waste liquid tube whose nozzle end is applied to, for example, a diseased part. A vacuum hose connected to a vacuum generator or the like is connected to the pipe. As the coagulant, a powdery or granular polymer absorber or the like is used, and when this coagulant is sprayed on the waste liquid collected in the waste liquid reservoir, the waste liquid is immediately solidified. Has become. In this waste liquid collector, the waste liquid reservoir, lid, inner plug, and operating part are all made of a flammable resin material, so the waste liquids that have been solidified are collected together and incinerated as a whole. To be done.

[0003]

Since the waste liquid is attached to the lower surface of the lid and the inside of the waste liquid injection pipe after the waste liquid is collected, this lid must also be incinerated together with the waste reservoir. It goes without saying that it must be done. However, in the lid body, there are left a storage portion which has become a hollow body after the coagulant has been sprayed, an operation portion of an inner plug which has become a useless elongated member, and the like. Therefore, it must be said that incinerating such a lid together with the waste liquid reservoir involves a wasteful surface in terms of energy and time. Transport again,
The presence of the lid also causes unnecessary space and extra weight in various operations such as handling and incineration.

The present invention has been made in view of the above circumstances, and by eliminating various wastes, cost reduction and improvement of working efficiency can be achieved, and it is further valuable as a waste liquid recovery device. An object of the present invention is to provide a waste liquid collector that can be used and a waste liquid treatment method using the same.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, in the waste liquid collector according to the present invention, the lid body is a cap body which is covered with the waste liquid reservoir and has a central opening penetratingly formed in the central portion of the upper surface, and a spraying capable of being fitted and held in the central opening of the cap body. It is characterized in that it can be disassembled into a coagulant tank having a mouth.

[0006] The inner plug has a diffusion taper surface that spreads toward the end with a portion corresponding to the center of the spout of the coagulant tank as the apex, and protrudes a predetermined length upward from the opposite position on the outer peripheral surface. The push-in operation piece that constitutes the operation portion can be provided by bending the pieces outwards later. In this case, each pushing operation piece
When the inner plug is removed from the spout, the central plug of the cap body is engaged with the inner plug so that the inner plug can be held in the air.

A storage recess is formed in the outer peripheral portion of the coagulant tank to avoid positional interference with the pushing operation piece.
The pushing operation piece is provided with a portion to be bent, which has a locally thin wall thickness.When the pushing operation piece is in the unused state, the pushing operation piece is placed in the storage recess. It can be configured so that it can be deformed to a posture protruding toward one side.

A disposable bag can be attached to the lower surface of the cap body. On the other hand, in the waste liquid treatment method using the waste liquid recovery device according to the present invention, after the waste liquid is recovered in the waste liquid reservoir, the operation part is operated to remove the inner plug from the spray port part, thereby Disperse the coagulant into the waste liquid reservoir, remove the empty coagulant tank from the cap body, then drop the inner plug into the waste liquid reservoir, and then fit the sealing lid on the center opening of the cap body to the waste liquid reservoir. The feature is that the whole is sent to the incineration process.

When the disposable bag is accommodated in the waste liquid reservoir, the waste liquid is collected in the disposable bag in the waste liquid reservoir, and then the operating portion is operated to remove the inner plug from the spray port portion, thereby causing the coagulant tank. Disperse the coagulant in the disposable bag,
Remove the empty coagulant tank from the cap body, then drop the inner plug into the waste liquid reservoir, then fit the sealing lid on the central opening of the cap body, and leave the cap body as a unit with the disposable bag from the waste liquid reservoir. Remove it and send it to the incineration process.

[0010]

According to the present invention, since the lid body can be disassembled into the cap body to be covered with the waste liquid reservoir and the coagulant tank for storing the coagulant, the coagulant tank can be removed after spraying the coagulant. It can be removed to reduce the overall bulk. By forming a diffusion taper surface on the upper outer peripheral surface of the inside plug, and when this is removed from the spray mouth part, by configuring the operation part so that the inside plug is suspended below the spray mouth part,
The coagulant can be sprinkled radially along the inner peripheral surface in the waste liquid reservoir.

The pushing operation piece forming the operation portion has a deformable structure so that the pushing operation piece can be put into and taken out from the storage recess formed on the outer peripheral surface of the coagulant tank, and rough handling in an unused state. Even if it is done, the pushing operation piece is not accidentally operated. If you attach a disposable bag to the cap body, after solidifying the waste liquid in this disposable bag, remove the cap body from the waste liquid reservoir,
Only the cap body and the disposable bag need to be incinerated, and the bulk can be further reduced.

In the waste liquid collector thus constructed, when the waste liquid is collected and inspected, the operating portion is operated to remove the inner plug, and after the spraying of the coagulant, the coagulant tank is removed from the waste liquid reservoir. However, by attaching a sealing lid to the central opening of the cap body which is opened by this, infection during handling is prevented. Even when the disposable bag is attached to the cap body, the sealing lid is also required.

The method of treating the waste liquid recovered by using the waste liquid recovery device 1 of the second embodiment is substantially the same as that of the first embodiment. However, when sending to the incineration process, remove the cap body 4 and the disposable bag 40 from the waste liquid reservoir 2,
All you have to do is send these. In the present invention, the shape and structure of each component, such as replacing the coupling structure of the waste liquid reservoir 2 and the cap body 4 by screwing or bonding, and making the coagulant tank 5 an assembly of a plurality of components, etc. Can be changed as appropriate.

[0021]

The present invention has the above-mentioned structure, and since the lid body can be disassembled into the cap body and the coagulant tank, the coagulant tank can be removed during the incineration process. It can be sent, eliminating energy and time waste. Further, with respect to various operations such as transportation, handling, and incineration, the problems of space and weight can be solved, so that the cost can be reduced and the work efficiency can be improved as a whole. Further, as compared with the previous application in which the lid body was integrated as a whole, disassembling into a cap body and a coagulant tank simplifies the structure of each part and reduces the size, resulting in improved productivity. There is also an advantage that is improved.

By forming a diffusion taper surface on the upper outer peripheral surface of the inner plug so that the inner plug can be held in the space directly below the spray port, the coagulant is removed from all the waste liquid in the waste liquid reservoir. It can be sprayed evenly, and reliable solidification can be obtained. Therefore, reliable prevention of infection can be achieved. If the pushing operation piece forming the operation portion is made deformable, it is possible to prevent erroneous operation and mischief when not in use. Further, it is possible to easily drop the inner plug into the waste liquid reservoir after use.

If a disposable bag is attached to the cap body, not only the coagulant tank but also the waste liquid reservoir can be sent to the incineration process, which is energy, time, space, and Further waste in weight is eliminated. After removing the coagulant tank, by fitting a sealing lid on the central opening of the cap body that is in an open state, the risk of infection can be completely prevented.
