Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for aspirating blood and other body fluids and secretions that need to be discarded at a medical site, or liquid waste such as pus or physiological saline used for cleaning an affected area. The present invention relates to a canister bottle used for a liquid waste treatment device for coagulating and discarding.

[0002]

2. Description of the Related Art In medical practice, liquid waste such as blood and other body fluids and secretions that need to be discarded, particularly during surgical operations, or pus or saline used for cleaning affected areas, It is collected in containers and collection bags by a suction machine and disposed of by incineration.

However, such liquid waste may contain harmful bacteria and the like, and the container and the collection bag may be damaged, or the liquid waste may be sucked in more than the capacity of the collection bag. In such a case, the liquid waste may leak to the outside and cause secondary infection to medical staff, hospitalized patients, and the like.

[0004] In order to prevent this, there is a type in which a water-absorbing material is placed in a collection bag to solidify liquid waste.
As a method of disposing a water-absorbing material that solidifies the liquid waste in the collection bag, a non-permeable sheet and a water-absorbent sheet are attached to each other, and a collection bag is formed such that the water-absorbent sheet is on the inner side, There are a type in which a water-absorbing material prepared after the liquid waste is sucked into the collection bag is dropped, and a type in which the water-absorbent material is fixed to the bottom of the collection bag.

As a conventional example of a canister bottle for sucking and storing liquid waste, as shown in FIG. 10A, an open end portion of a flexible collection bag 51 for storing sucked liquid waste is used. In some cases, the fitting portion 52a of the lid 52 is fitted and fixed by bonding or welding, and the collection bag 51 is accommodated in the outer container 53 and the lid 52 is fixed to the open end of the outer container 53. .

When the collection bag 51 is fixed to the lid 52, the
As shown in (b), a hot melt adhesive 54 is applied to the outer wall surface of the fitting portion 52a of the lid 52, and the opening end of the collection bag 51 is fitted into the fitting portion 52a to make the outside of the collection bag 51 outside. By heating and pressing the hot melt adhesive 54 from the
Weld and fix.

[0007]

However, in the above-mentioned conventional example, as shown in FIG. 10, the collection bag 51 and the lid 52 are fixed to each other by the outer wall surface of the fitting portion 52a of the lid 52 and the opening end of the collection bag 51. When the collection bag 51 has a relatively large capacity because the configuration depends only on the adhesive force of the hot melt adhesive 54 between the collection bag 51 and the liquid waste is fully contained in the collection bag 51. When the weight is increased and the adhesive strength of the hot melt adhesive 54 is insufficient, the collection bag 51 may come off the fitting portion 52a of the lid 52 and the liquid waste may be scattered.

When the collecting bag 51 is formed by laminating a water-impermeable sheet and a water-absorbing sheet, the inside becomes invisible due to the multi-layer structure, and it is difficult to fold, so that it can be stored and transported. There was inconvenience.

When a water-absorbing material to be dropped after sucking the liquid waste is prepared in the collection bag 51, coagulation does not occur until the water-absorbing material is dropped. Anxiety remained, and it was not possible to perform additional suction after coagulation.

In the case where the water-absorbing material is fixed to the bottom of the collection bag 51, there is a problem that the solidification rate decreases as the suction of the liquid waste proceeds.

The present invention has been made to solve the above problems, and
The purpose is to increase the capacity of the canister bottle to increase the liquid waste collection and processing capacity, and to store the sucked liquid waste in a bag, and a lid fixed to the open end of the bag. It is an object of the present invention to provide a canister bottle capable of securing the reliability of fixation, easily recognizing the content, and solidifying the sucked liquid waste more quickly.

[0012]

According to a first aspect of the present invention, there is provided a canister bottle comprising: a bag for storing sucked liquid waste; an annular fitting portion fitted to the bag; A lid having a flange continuous with the fitting portion and projecting radially outward of the fitting portion; and a holder fitted to the lid with an opening end of the bag interposed therebetween. The end portion extends from the fitting portion of the lid to the flange portion, and is adhered or welded to the fitting portion and the flange portion.

According to the present invention, as described above, the opening end of the bag is extended from the fitting portion of the lid to the flange portion, and is adhered or welded to the fitting portion and the flange portion. Since it is fitted and fixed to the lid via the opening end, the fixing strength between the bag and the lid fixed to the opening end of the bag is improved, and the reliability of the fixing can be secured. .

Therefore, it is possible to easily increase the capacity of the canister bottle to increase the liquid waste collection and processing capacity.

In the case where the holder has an outer container which accommodates the bag and the holder is attached to an open end,
The double-structured canister bottle can be easily formed by housing the bag inside the outer container and attaching the holder fitted and fixed to the lid via the open end of the bag to the open end of the outer container. Can be configured.

When a coagulant is provided inside the bag, the liquid waste is coagulated in the bag and the bag can be discarded, so that sanitary treatment can be performed.

Is extended from the fitting portion 3a to the flange portion 3b, and is bonded or welded to the fitting portion 3a and the flange portion 3b.
Is fixed to the lid 3 via the opening end of the bag 4 so that the fixing strength between the bag 4 and the lid 3 fixed to the opening end of the bag 4 is improved, and the reliability of the fixing is improved. Nature can be secured.

Therefore, the capacity of the liquid waste 21 can be easily increased by increasing the capacity of the canister bottle E.

Further, since the bag 4 is accommodated and the holder 10 has the bottle M as an outer container to be attached to the opening end, the bag 4 is accommodated inside the bottle M and the bag 4 is accommodated.
Holder fitted and fixed to the lid 3 via the opening end of
By attaching 10 to the opening end of the bottle M, the canister bottle E having a double structure can be easily configured.

In addition, since the bag 5 has the float 5 having the water-absorbing material 6 serving as a coagulant inside, the liquid waste 21
Can be coagulated in the bag 4 and the entire bag 4 can be discarded, so that sanitary treatment can be performed.

Further, since the float 5 having a specific gravity of less than 1 and holding the water-absorbing material 6 is provided inside the bag 4, the float 5 is always maintained at a position floating above the gas-liquid interface. By checking the position of 5, the position of the liquid level can be easily checked from the outside, and the user can surely check the use state of the canister bottle E and the remaining allowable capacity.

In the above embodiment, the annular member 5a, the cup portion 5b and the fixing ring 23 of the float 5 are formed of polypropylene having a specific gravity smaller than 1.
The material is not limited as long as the specific gravity is smaller than 1.

Although the shape of the float 5 is a shape in which a cup is closed, the present invention is not limited to this, and a cylinder having a top surface similar to the top end surface 5b1, a polygonal tube, or a ring-shaped tube is provided. Any structure may be used as long as the water-absorbing material 6 is held at the center of the float by an arm, that is, a material whose lower part is opened. Further, it is preferable to have a hole for venting air, a cut or the like so that air does not accumulate inside the cup portion 5b serving as a holding container for holding the water absorbing material 6.

The water-permeable sheet 22 made of Japanese paper or the like covering the opening of the cup 5b is used as the holding means for holding the water-absorbing material 6 in the cup 5b. In addition, various holding means are conceivable, such as fixing the water-absorbing material 6 with a filler that dissolves in water, holding the water-absorbing material 6 with a non-woven paper or non-woven fabric that decomposes with water.

In the above-described embodiment, an example in which the float 5 is housed inside the flexible liner L has been described. However, the float 5 is housed in a non-flexible container, and It is also possible to apply.

Since the present invention has the above-described structure and operation, the open end of the bag is extended from the fitting portion of the lid to the flange portion and is adhered or welded to the fitting portion and the flange portion. Further, since the holder is fitted and fixed to the lid via the opening end of the bag, the fixing strength between the bag and the lid fixed to the opening end of the bag is improved, and the reliability of the fixing is improved. Can be secured.

Therefore, it is easy to increase the capacity of the canister bottle to increase the liquid waste collection and processing capacity.

When the bag is accommodated and the holder has an outer container attached to the opening end, the bag is accommodated in the outer container and fitted to the lid via the opening end of the bag. By attaching the fixed holder to the opening end of the outer container, a canister bottle having a double structure can be easily formed.

When a coagulant is provided inside the bag, the liquid waste is coagulated in the bag, and the entire bag can be disposed of, thereby achieving sanitary treatment.

Also, the specific gravity is smaller than 1 inside the bag,
In addition, when a float holding a coagulant is used, the float is always maintained at the position where it floats at the gas-liquid interface, so the position of the liquid surface can be easily checked from the outside by checking the position of the float. The user can surely check the use state of the canister bottle and the remaining allowable capacity.
