Abstract

PROBLEM TO BE SOLVED: To prevent the excessive suction of liquid waste without freshly installing mechanisms by arranging a float of a prescribed sp. gr. or below for holding water absorbent materials into a holding vessel opened downward into the bottom of a treating unit, thereby facilitating visibility and making gelatinization fast. SOLUTION: The float 5 is positioned in the bottom of the treating unit 2 before the start of the suction. The liquid waste 6 arrives at the lower side of the float 5 by passing the space between the collecting bag of the treating unit 2 and the holding vessel of the float 5 when the suction of the liquid waste 6 into collecting bag is started. Then, the sp.gr. of the float 5 is <=1 and, therefore, the water-soluble film on the rear surface of the float 5 dissolves while floating at the air-liquid boundary, thereby gelatinizing the liquid waste. The float 5 exists at the air-liquid boundary at all times when the suction of the liquid waste is progressed thereby efficiently diffusing the waste absorbent materials into the liquid waste 6 sucked afterward and gelatinizing the waste. The float 5 rises to the top end and closes the liquid passage for discharge.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention sucks liquid waste, for example, blood and other body fluids that need to be discarded in a medical field, or physiological saline used for cleaning an affected area. , A treatment device for coagulation treatment and disposal.

[0002]

2. Description of the Related Art In a medical field, wastes such as blood and physiological saline, which need to be discarded especially when performing a surgical operation, are collected in a container by an aspirator and disposed of by incineration. However, such waste may contain harmful bacteria, etc., and if the container or bag is damaged or liquid waste is aspirated more than the capacity of the collection bag, the waste is There is a case that it leaks to the outside and secondarily infects medical personnel and inpatients. Further, if the liquid is excessively sucked and flows into the air pump, the air pump may be damaged.

In order to prevent this accident, normally, the liquid waste that has been sucked is solidified by using the water-absorbing high-molecular polymer disposed in the collection bag, and is not discarded, or is sucked over a certain amount. There are various devices.

As a method of arranging a water-absorbent material for solidifying liquid waste in a collection bag, a water-impermeable sheet and a water-absorbent sheet are stuck together to form a collection bag with the water-absorbent sheet on the inner surface side. Objects or those that drop the water absorbent material prepared after sucking liquid waste into the collection bag,
In addition, there is one in which a water absorbent material is fixed to the bottom of the collection bag.

As a device for preventing excessive suction of liquid waste, there is usually a device in which a float having a rod at the exhaust port is prepared so that the rod closes the exhaust port as the water level rises. .

[0006]

However, the processing device constructed by laminating a water-impermeable sheet and a water-absorbing sheet has a multi-layered structure, the inside is invisible, and it is difficult to fold and is stored and transported. I had some inconvenience. In addition, in a processing device that prepares a water-absorbent material that is dropped into a collection bag after sucking liquid waste, coagulation naturally does not occur until the water-absorbent material is dropped, so there is anxiety when falling over during work. Moreover, it was not possible to perform additional suction after coagulation once. Further, in the processing device in which the water absorbent material is fixed to the bottom of the collection bag, there is a problem that the coagulation rate decreases as the suction of the liquid waste progresses.

Therefore, an object of the present invention is, in a liquid waste treatment apparatus in which a container and a collection bag are separate bodies, the contents of the liquid can be easily visually recognized, gels more quickly, and is liquid without a new mechanism. An object of the present invention is to provide a liquid waste treatment device that prevents excessive suction of waste.

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described in detail below with reference to the drawings. The present embodiment relates to a medical liquid waste treatment apparatus, in which blood to be discarded generated during surgery or treatment and physiological saline for washing are sucked into the treatment unit and incinerated together with the treatment unit. It is something to dispose of. 1 is an exploded perspective view of a liquid waste treatment apparatus according to the present embodiment, FIG. 2 is an external side view of the liquid waste treatment apparatus, FIG. 3 is a partial sectional view of the liquid waste treatment apparatus, and FIG. Is a configuration diagram of the float, FIG. 5 is a perspective view showing a folded state of the processing unit, FIG. 6 is a diagram illustrating an operation when the processing device is used, and FIG. 7 is a perspective view showing a disposal method after the processing unit is used. It is a figure.

As shown in FIG. 1, the processing apparatus 1 is equipped with a processing unit 2 for storing liquid waste, a bottle 3 as a container for containing the processing unit 2, and an outer side of the bottle 3.
It is composed of a holder 4 for holding the processing apparatus 1.

Further, as shown in FIGS. 2 and 3, when the processing unit 2 is inserted into the bottle 3, the lid 22 contacts the peripheral edge of the opening of the bottle 3, and the bottom plate 23 of the collecting bag 21 is the bottle. Three
Touch the inner bottom of. Then, by fixing the lid 22 of the processing unit 2 to the bottle 3 using the fixing hook 44 of the holder 4, the processing unit 2, the bottle 3 and the holder 4 are integrally fixed, and the bottle 3 is sealed by the lid 22.

The bottle 3 is a cylindrical transparent plastic container and has a scale 31 on its surface. Further, the lid 22 of the processing unit 2 is fitted into the upper end of the opening in the upper portion of the bottle 3, and is fixed airtightly by the fixing hook 44 of the holder 4.

The holder 4 is formed by integrally molding a bracket 43 for fixing the handle 42 and the processing apparatus 1 on a wall, a rack, or the like, to an annular body 41 fitted and fixed to the upper portion of the bottle 3. Further, the annular body 41 has a fixing hook 44 for fixing the processing unit 2 to the bottle 3.

The processing unit 2 is a unit in which a circular plastic lid 22 is heat-welded and integrated with an opening of a collection bag 21 made of low-density polyethylene. A bottom plate 23 made of plastic or paper is attached to the bottom of the collection bag 21. The outer shape of the bottom plate 23 is configured to match the inner bottom of the bottle 3. The float 5 is placed on the bottom plate 23 in the processing unit 2.

The lid 22 has an exhaust port 24 for discharging air from the collection bag 21 and a suction hole 25 for sucking liquid waste into the collection bag 21. L-shaped joints 11 and 12 are attached to the exhaust port 24 and the suction port 25, respectively, in a gas-tight and detachable manner using gaskets. Patient Horse 1
3, and the primary hose 14 connected to the air pump is attached. Further, in order to easily take out the processing unit 2 in which the liquid waste 6 has accumulated from the bottle on the lid 22,
A handle 26 is attached.

The gas passage inside the joint 12 of the exhaust port is divided into two, and the gas is sucked through the first passage 24a for sucking gas from the inside of the processing unit 2 and the gap between the processing unit 2 and the bottle 3. It consists of a second communication passage 24b for sucking.
That is, with this structure, the gas is sucked from the inside of the processing unit 2 and at the same time from the gap between the processing unit 2 and the bottle 3, so that the atmospheric pressure inside and outside the processing unit 2 becomes equal in the bottle 3, and the processing unit 2 Even if the second collection bag 21 is made of a flexible sheet, suction can be performed without contraction.

At the end portion 27 of the exhaust port 24 inside the collection bag 21, there is formed a connecting portion 28 spreading downward in a funnel shape. A stop valve filter 29 is adhered to the inside of the connecting portion 28. The connecting portion 28 is formed in a pair with a connecting guide 51c of the float 5 described later to form a connecting structure for connecting the end portion 27 of the exhaust port and the float 5, and the float 5 rises to the top end of the processing unit 2. When floating, the connecting portion 28 and the connecting guide 51c come into close contact with each other with the suction force of the exhaust gas, and stop the suction of the liquid waste 6.

The stop valve filter 29 is a porous body obtained by sintering a polymer, and is formed by mixing a water-absorbing polymer and an antibacterial agent in a molding material at the time of molding and performing foam molding. Since this stop valve filter 29 is a porous body, it normally passes gas as a filter,
Antibacterial agents suppress bacteria contained in exhaust gas. On the other hand, when the liquid waste 6 comes into contact with the stop valve filter 29, the contained water-absorbing polymer absorbs water and expands, blocking the pores of the porous body and impeding the passage of the liquid waste. As a result, even if the processing device is turned over, the liquid waste 6 does not leak.

A float 5 is placed on the bottom 23 of the processing unit 2.
Is placed. The float 5 is configured to have a specific gravity of 1 or less, and when the liquid waste 6 flows into the processing unit 2, it always floats and is located at the gas-liquid interface.

The holding container 51 of the float 5 is made of polypropylene, has a cup-like shape as shown in FIG. 4, and is open at the bottom. The outer diameter of the float 5 is formed to be smaller than the inner diameter of the collection bag 21, and the sucked liquid waste can flow into the lower side of the float 5 through this gap. Further, a connection guide 51c is provided on the upper surface of the float 5, and is formed in a pair with the connecting portion 28 of the exhaust port, and is configured to close the exhaust port by abutting.

A step portion 51a is formed at the edge of the inner surface of the holding container 51, and a projection 51b is provided on the step portion 51a. Inside the holding container 51 of the float 5, the water absorbent material 52 is filled up to the step 51a, and the water absorbent film 53 is fixed by covering the step 51a with the water-soluble film 53.
The water-soluble film 53 is fixed by fitting a film fixing ring 54 to the. The film fixing ring
A notch is provided all around the outer circumference of 54, and the protrusion 51b of the holding container is fitted into this notch to fit.

Next, the use procedure and operation of the liquid waste treatment apparatus 1 will be described with reference to FIGS. 5, 6 and 7. As shown in FIG. 5, the processing unit 2 has a lid before use.
The bag portion of the collection bag 21 is folded so that the bottom plate 23 and the bottom plate 23 are aligned with each other, and the bag is stored and transported by sealing it in a vinyl packaging container. At this time, since the handle 26 can be laid down on both sides of the lid 22 and the joints 12 and 13 to each hose can be removed, the handle 26 becomes extremely compact and can be stored and transported without taking up much space.

In use, the bottom plate 23 can be separated from the lid 22, the collecting bag 21 can be extended and inserted into the bottle 3, and can be easily attached to the processing apparatus 1. At this time, if the bottom plate 23 is configured to have a predetermined weight, the weight of the bottom plate 23 allows the collecting bag 21 to be stretched without wrinkles.

As shown in FIG. 6 (a), the float 5 is located at the bottom of the processing unit 2 before suction is started.
When suctioning of the liquid waste 6 into the collection bag 21 is started, the liquid waste 6 reaches the lower side of the float 5 through the gap between the collection bag 21 of the processing unit 2 and the holding container 51 of the float 5.

Then, as shown in FIG. 6 (b), the float 5
Since it has a specific gravity of 1 or less, the water-soluble film 53 on the lower surface of the float 5 dissolves and the water-absorbent material diffuses while floating at the gas-liquid interface, and gels the liquid waste. Further, even when the suction of the liquid waste 6 progresses, the float 5 is always present at the gas-liquid interface, and the water-absorbent material can be effectively diffused into the liquid waste 6 sucked afterwards to cause gelation. . Also, since the float 5 is always at the gas-liquid interface,
The amount of sucked liquid waste can be easily visually checked, and the function as a level gauge can be achieved.
For this reason, it is more preferable to mold the holding container 51 of the float 5 with a material having a prominent color such as red or fluorescent color.

As shown in FIG. 6 (c), as the suction work progresses, the float 5 rises to the top of the processing unit,
The connecting guide 51c on the upper part of the float 5 and the connecting part 28 of the exhaust port
Abut. Then, the connecting portion 28,
The connection guide 51c is in close contact with the exhaust passage, and
No negative pressure is applied to the processing unit 2. Therefore, the suction of the liquid waste 6 is stopped, and there is no fear that the air pump is damaged by excessive suction.

As shown in FIG. 7, when the processing unit 2 is removed from the bottle 3 after use, the exhaust port 24 and the suction port 25 are used.
The processing unit 2 is covered with caps 15 and 16 respectively.
After the seal is closed, the fixing hook 44 of the holder 4 is released, and the handle 26 of the lid 22 is used to pull it up to easily separate it.
Can be discarded. The used processing unit 2 is incinerated as it is. At this time, when the liquid waste 6 is solidified, the processing unit 2 can be erected and handled as a single unit by the action of the bottom plate 23.

A second embodiment of the liquid waste treatment apparatus according to the present invention will be described with reference to FIG. The same parts as those of the first embodiment will be designated by the same reference numerals and the description thereof will be omitted.

In the present embodiment, the end of the suction port 73 inside the processing unit 2 is bent toward the wall surface of the collecting bag 21 of the processing unit 2, and the sucked liquid waste 6 is caused to flow along the wall surface. It has a structure that suppresses turbulence of the liquid surface.

Further, the end of the exhaust port inside the processing unit 2
27 is formed into a cylinder, and a rubber suction cup 72 is joined to the outer periphery of the end portion 27. The end portion 27 and the suction cup 72 are formed by fitting a recess provided all around the edge of the outer surface of the end portion 27 and a projection portion provided all around the inner surface of the upper cylinder of the suction cup 72. Are joined by. Further, similarly to the first embodiment, a stop valve filter 29 is adhered to the inside of the end portion 27, so that the liquid waste 6 is reliably prevented from flowing out of the container.

The holding container 71 of the float 7 has a cylindrical shape with its upper surface closed, and its lower surface is open. Example 1
In the float 5 in the above, a raised portion is provided on the upper surface as the connecting guide 51c, but the float 7 in the present embodiment.
The upper surface of is only flat.

When the liquid waste 6 is sucked, the float 7 floats on the gas-liquid interface and diffuses the water absorbing material 52 to gel the liquid waste 6. Then, when the float 7 reaches the top end of the processing unit 2, the suction cup 72 at the end 27 of the exhaust port is adsorbed on the upper surface of the float 7 by the suction force of the exhaust gas to close the exhaust gas passage. Since it is necessary to pass the liquid waste below the float 7, a gap is formed between the float 7 and the processing unit 2 as described above, and the float 7 moves in the horizontal direction, but the suction cup 72 causes the float 7 to move. Since it can be adsorbed on any part of the upper surface, the exhaust port can be reliably closed.

In the above embodiment, the holding container is made of polypropylene, but the material is not limited as long as the specific gravity is 1 or less. Further, the shape of the holding container is the one covered with the cup, but the present invention is not limited to this, and a cylinder having an upper surface or a polygonal tube, and a central part of a ring-shaped float absorbs water by an arm. Any material such as a material-holding material, that is, a material whose bottom is opened may be used. It is also preferable to have an air vent hole or a cutout so that air does not collect inside the holding container.

Further, the water-soluble film is used to hold the water-absorbent material in the holding container, but the water-absorbent material holding means may also be a means for holding the water-absorbent material, for example, by a filler that dissolves in water. Various means are conceivable, for example, holding by non-woven paper or non-woven fabric which is decomposed by water.

In the above embodiment, the exhaust port connecting portion 28
The stop valve filter provided in does not have to be used together with the float according to the present invention, but by being provided alone in a conventional liquid waste treatment device,
It is possible to prevent liquid waste from leaking due to excessive suction or falling. Although the stop valve filter is provided inside the processing unit, it may be provided outside the processing unit or in the middle of the primary hose connected to the air pump.

The stop valve filter was made by sintering a polymer and foam-molding it. As another forming method, a water-absorbing polymer is wrapped with cotton or the like in which pulp, polypropylene, polyethylene, etc. are mixed and heated and compressed to harden it. It may be one. At this time, it is preferable to protect the filter surface with a nylon mesh or the like with respect to the air circulation path so that the fibers constituting the cotton do not scatter.

[0038]

In the liquid waste treatment apparatus according to the present invention, since the float holding the water-absorbing material is configured to have a specific gravity of 1 or less, when the liquid waste is sucked into the treatment unit, the float is always kept. It will be located at the gas-liquid interface. As a result, the water absorbing material can be always diffused into the newly sucked liquid waste, and gelation can be performed quickly and effectively. Further, even when suction is once stopped and then suction is again performed, gelation can be rapidly advanced. In addition, it can also have a function as a level gauge showing the content volume. In addition, since the structure is simple, the manufacturing cost is low.

Further, the upper surface of the float and the exhaust port are provided with a coupling structure, and the upper surface of the float closes the exhaust port when the float reaches the top of the processing unit.
Exhaust gas suction can be stopped without excessive suction, and liquid waste does not leak to the air pump side. Therefore, the failure of the air pump can be prevented, and the bacteria contained in the liquid waste can be prevented from leaking.
