Description

[0001]
BACKGROUND OF THE INVENTION
The present invention, for example, sucks and coagulates and discards liquid waste such as blood and other bodily fluids and secretions that need to be discarded in a medical field, or pus or saline used to wash affected areas. The present invention relates to a liquid waste treatment apparatus.
[0002]
[Prior art]
In medical settings, liquids such as blood and other bodily fluids and secretions that are generated when performing surgical operations and that must be disposed of, or liquid waste such as physiological saline used to clean pus or affected areas should be stored in a container or They are collected in collection bags and disposed of by incineration.
[0003]
However, such liquid waste may contain harmful bacteria, etc., and if the container or collection bag is damaged or if liquid waste is aspirated excessively beyond the capacity of the collection bag, There is a risk that waste may leak to the outside and secondary infection may occur in medical workers, hospitalized patients, and the like.
[0004]
In order to prevent this, there is a device for disposing a water-absorbing material in the collection bag and solidifying the liquid waste, but as a method for disposing the water-absorbing material for solidifying the liquid waste in the collection bag, a water impermeable material The sheet and the water-absorbent sheet are bonded together to form the collection bag so that the water-absorbent sheet is on the inner surface side, or the water-absorbing material prepared after the liquid waste is sucked into the collection bag is dropped. Some have a water-absorbing material fixed to the bottom of the collection bag.
[0005]
In order to increase the collection capacity of liquid waste, two collection bags or four or six on a vehicle seat on the same circumference have been proposed.
[0006]
[Problems to be solved by the invention]
However, in the above-described conventional example, when a large number of collection bags are connected to the vehicle seat on the same circumference in order to increase the collection capacity of liquid waste, it is impossible to see all the collection bags from one direction. Therefore, the user of the processing apparatus could not easily check how much storage capacity is available.
[0007]
In addition, a processing apparatus constituted by bonding a water-impermeable sheet and a water-absorbing sheet has a multi-layer structure, so that the inside becomes invisible, is difficult to fold, and is inconvenient to store and transport.
[0008]
In addition, in a processing device that has prepared a water-absorbing material to be dropped after liquid waste has been sucked into the collection bag, naturally coagulation does not occur until the water-absorbing material is dropped. In addition, after solidifying once, additional suction could not be performed.
[0009]
Moreover, in the processing apparatus in which the water-absorbing material is fixed to the bottom of the collection bag, there is a problem that the solidification rate decreases as the suction of the liquid waste proceeds.
[0010]
The present invention solves the above-mentioned problems, and the object of the present invention is to easily recognize the internal volume even if the collection capacity of liquid waste is increased, and to solidify the sucked liquid waste faster. It is an object of the present invention to provide a multiple-type liquid waste treatment apparatus that can perform such a process.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a multiple-type liquid waste treatment apparatus according to the present invention has a suction port and a discharge port, stores liquid waste sucked from the suction port, and removes the stored liquid waste. Is a multiple-type liquid waste treatment apparatus in which n canister bottles (n ≧ 3) that can be visually recognized are connected, the first canister bottle discharge port, the second canister bottle suction port, and the second canister bottle The discharge port of the third canister bottle, the discharge port of the n-1 canister bottle, and the suction port of the nth canister bottle, and these canister bottles are connected to the first canister bottle from the first canister bottle. n canister bottles are arranged in a straight line in order, and the inside of the upper end of the canister bottle discharges air from the canister bottle to make the inside negative pressure. Communicating with each suction passage connected in parallel to the primary suction hose A stop valve capable of closing the suction passage of the exhaust port is provided, and the stop valve is maintained at a lower position by the dead weight of the stop valve while the float in the canister bottle does not float up to the top end portion. The float is sucked into the canister bottle and the float floated by the liquid waste rises and reaches the top end of the canister bottle. The stop valve is lifted against the dead weight of the stop valve, and the suction passage is closed.
[0012]
Since the present invention is configured as described above, the canister bottles are arranged in a straight line in the order of the first canister bottle to the nth (n ≧ 3) canister bottle, so that all the canister bottles can be seen from one direction. Since the liquid waste is stored in the order of the canister bottles from the first canister bottle to the nth canister bottle, it is determined how much storage capacity the user of the processing apparatus has. It can be easily confirmed.
[0013]
Further, when the canister bottle is composed of an outer container and an inner bag housed in the outer container and having a coagulant inside, the liquid waste is solidified in the inner bag, Can be disposed of, and a sanitary treatment device can be obtained.
[0014]
Further, when the inner bag of the canister bottle has a float having a specific gravity smaller than 1 and holding the coagulant on the inner side, the float is always kept at the position where it floats on the gas-liquid interface. By confirming the position, the position of the liquid level can be confirmed from the outside, and the user can surely confirm the use state of the canister bottle and the remaining allowable capacity.

[0039]
On the other hand, as shown in FIG. 5, a suction passage 19 communicates with the suction passage 13, and the suction passage 19 is connected to a gap space between the bottle M and the liner L. Since the suction pressure inside the liner L and the suction pressure in the gap space between the bottle M and the liner L are made negative with the same suction pressure, the pressure inside and outside the liner L in the bottle M becomes equal. The liner L made of a flexible sheet is maintained in the state shown in FIG. 5 without expanding and contracting, and stable suction can be performed.
[0040]
A stop valve 9a is provided inside the end portion of the exhaust port 9 in the liner L. The stop valve 9a is provided in the canister bottle E shown in FIG. ₂ , E ₃ , E ₄ As shown in FIG. 5, while the float 5 does not float up to the top end, it is maintained at the lower position by the dead weight of the stop valve 9a, thereby securing the suction passage 20 communicating from the inside of the liner L to the suction passage 13. Yes.
[0041]
On the other hand, canister bottle E in FIG. ₁ As shown in FIG. 5, when the liquid waste 21 is sucked into the liner L and the float 5 floated by the liquid waste 21 rises and reaches the top end of the liner L, the top end surface 5b1 of the float 5 is The stop valve 9a is raised against the dead weight of the stop valve 9a by contacting the stop valve 9a, and the suction passage 20 communicating with the suction passage 13 from the inside of the liner L is closed.
[0042]
Once the stop valve 9a is raised and the suction passage 20 is closed, the stop valve 9a is in close contact with the cylindrical body 9b provided on the upper portion with the suction force of the exhaust, and the suction passage 20 is closed. Retained.
[0043]
A float 5 shown in FIGS. 9 and 10 is placed on the bottom 4 of the liner L. The float 5 has a specific gravity smaller than 1. When the liquid waste 21 flows into the liner L as shown in FIG. 11, the float 5 always floats to the level of the liquid waste 21 and reaches the gas-liquid interface. To position.
[0044]
The float 5 is supported in a shape in which an inner surface edge of the annular body 5a is filled with a water absorbing material 6 such as a water absorbing polymer serving as a coagulant and is held, and the annular body 5a of the present embodiment is supported. The cup portion 5b is made of polypropylene having a specific gravity smaller than 1.
[0045]
As shown in FIGS. 4 to 7, the outer diameter of the annular body 5 a of the float 5 is smaller than the inner diameter of the liner L, and when the float 5 is housed inside the liner L, it is below the cup portion 5 b. Is open.
[0046]
When filling the cup portion 5b of the float 5 with the water absorbent material 6, as shown in FIG. 10, after filling the cup portion 5b with the water absorbent material 6 with the float 5 turned upside down, The fixing ring 23 is fitted in a state where the water-permeable sheet 22 such as Japanese paper is covered at the peripheral portion, and the claw portion 23a of the fixing ring 23 is locked to the step portion 5b2 formed at the peripheral portion of the cup portion 5b.
[0047]
Then, the liquid waste 21 sucked into the liner L from the suction port 7 goes down through the gap between the liner L and the annular body 5a of the float 5 or the gap between the annular body 5a and the cup portion 5b. The water permeable sheet 22 spread on the peripheral edge of the cup portion 5b penetrates into contact with the water absorbent material 6, the water absorbent material 6 expands, the water permeable sheet 22 is broken, and the water absorbent material 6 becomes a liner. The liquid waste 21 is dissolved in the liquid waste 21 accommodated in L and solidified in a gel state.
[0048]
Next, the use procedure and operation | movement of the said liquid waste processing apparatus 1 are demonstrated in detail. The liner L is stored and transported by sealing it in a vinyl packaging container with the holder 10 attached. At this time, the handle 10a provided on the holder 10 can be tilted to both sides of the lid 3, and since the liner L itself has flexibility, it can be stored and transported relatively compactly.
[0049]
In use, as many liners L as the number of bottles M arranged in a straight line on the stand 2 are prepared. First, the adjustment handle 17a is turned counterclockwise in FIG. The adapter 18a of the primary suction hose 18 is connected to a terminal outlet of a medical gas piping facility (not shown) or an air pump.
[0050]
Next, the canister head 12 of the stand 2 is opened, the liner L is inserted into all the bottles M, and can freely rotate to the discharge port 8 formed in the lid 3 provided at the top end of each liner L. The connecting pipe 15 attached and attached is inserted into and connected to the suction port 7 formed in the lid 3 provided at the top end of the liner L adjacent to the left side of FIG.
[0051]
And the first canister bottle E ₁ Liner L ₁ A fourth canister bottle E, which is the final stage, is inserted into and connected to the suction port 7 formed in the lid 3 provided at the top end of the side of the patient hose 14 on the side where the valve member 14a is provided. ₄ Liner L ₄ The connecting pipe 15 connected to the discharge port 8 formed in the lid 3 provided at the top end of the liner L ₄ The plug 3 is inserted into a closing plug 16 formed on the lid 3 and closed.
[0052]
Next, the canister head 12 is closed and locked to the stand 2. As shown in FIG. 4, before the suction is started, the float 5 is positioned on the bottom 4 of the liner L due to its own weight.
[0053]
Next, the adjustment handle 17a of the controller 17 is turned in the clockwise direction in FIG. At this time, the negative pressure of the primary suction hose 18 is passed through the suction passage 13 formed in each canister head 12 and the suction passage 20 of the exhaust port 9 formed in the lid 3 provided at the top end portion of each liner L. Thus, the inside of the liner L is set to a negative pressure, and the gap between the bottle M and the liner L is set to a negative pressure via the suction passage 19 communicating with the gap between each bottle M and each liner L.
[0054]
At this time, the tip of the patient hose 14 is closed to confirm that there is a suction pressure in the liner L and to confirm that the liner L swells along the bottle M.
[0055]
When the tip of the patient hose 14 is applied to the affected area of the patient and the suction of the liquid waste 21 is started, the liquid waste 21 is fed from the patient hose 14 to the first canister bottle E as shown in FIG. ₁ Liner L ₁ The liner L through a suction port 7 formed in the lid 3 ₁ Led in.
[0056]
Liner L ₁ Liquid waste 21 sucked into the liner L ₁ And reaches the lower side of the float 5 through a gap between the annular body 5a of the float 5 or a gap between the annular body 5a of the float 5 and the cup portion 5b.
[0057]
Then, the float 5 is positioned at the level of the liquid waste 21 because the specific gravity is less than 1, and the liquid permeable sheet 22 stretched on the outer periphery of the lower surface of the cup portion 5b of the float 5 is liquid discarded while floating at the gas-liquid interface. The material 21 permeates and contacts the water absorbent material 6, the water absorbent material 6 expands and the water permeable sheet 22 is broken, the water absorbent material 6 diffuses into the liquid waste 21, and the liquid waste 21 is It solidifies into a gel.
[0058]
Further, even when the suction of the liquid waste 21 proceeds, the float 5 is always present at the gas-liquid interface, and the water-absorbing material 6 is effectively diffused into the liquid waste 21 sucked later, so that the liquid waste 21 can be solidified in a gel form.
[0059]
Further, since the float 5 is always at the gas-liquid interface, the amount of the liquid waste 21 sucked can be easily visually confirmed, and can also function as a level gauge. For this reason, it is more preferable to form the annular body 5a, the cup portion 5b, and the like of the float 5 with a material having a conspicuous color such as a color that easily distinguishes from the color of the liquid waste 21 or a fluorescent color.
[0060]
As shown in FIG. 11, when the suction operation of the liquid waste 21 proceeds, the float 5 rises to the top end portion of the liner L, and the top end surface 5b1 of the cup portion 5b of the float 5 resists the dead weight of the stop valve 9a. Then, the stop valve 9a is pushed up, and the first canister bottle E in FIG. ₁ As shown, the suction passage 20 is closed and the suction pressure from the exhaust port 9 is stopped.
[0061]
Liner L ₁ When the suction pressure inside stops, the next liner L adjacent to the left side of FIG. ₂ Suction pressure of the stand 2 suction passage 13, liner L ₂ Suction passage 20 at the exhaust port 9 and liner L ₂ , The liner L ₂ Suction port 7, connecting pipe 15 and liner L ₁ Liner L through the outlet 8 ₁ Acting inside the liner L ₁ The liquid waste 21 that has not yet been gelled and is sucked upward from the float 5 inside the liner L ₁ Outlet 8, connecting pipe 15, liner L ₂ The liner L through the suction port 7 ₂ Sucked in.
[0062]
Liner L ₂ When the level (water level) of the liquid waste 21 contained in the inside rises, the liner L described above ₁ In the same manner as above, the float 5 floats to the level position of the liquid waste 21, and the float 5 becomes the liner L. ₂ When the top end portion of the float 5 is reached, the stop valve 9a is pushed up by the top end surface 5b1 of the float 5 so that the suction passage 20 is closed and the liner L ₂ The suction pressure inside stops.
[0063]
Similarly liner L ₂ Liner L next to ₃ Liner L by suction pressure of ₂ The liquid waste 21 sucked upward from the float 5 inside the liner L ₂ Outlet 8, connecting pipe 15, liner L ₃ The liner L through the suction port 7 ₃ Sucked in.
[0064]
Similarly, liner L ₃ When the level (water level) of the liquid waste 21 contained in the inside rises, the liner L described above ₁ , L ₂ In the same manner as above, the float 5 floats to the level position of the liquid waste 21, and the float 5 becomes the liner L. ₃ When the top end portion of the float 5 is reached, the stop valve 9a is pushed up by the top end surface 5b1 of the float 5, and the suction passage 20 is closed. ₃ The suction pressure inside stops.
[0065]
Similarly liner L ₃ Liner L next to ₄ Liner L by suction pressure of ₃ The liquid waste 21 sucked upward from the float 5 inside the liner L ₃ Outlet 8, connecting pipe 15, liner L ₄ The liner L through the suction port 7 ₄ Sucked in.
[0066]
Similarly liner L ₄ When the level (water level) of the liquid waste 21 contained in the inside rises, the liner L described above ₁ , L ₂ , L ₃ In the same manner as above, the float 5 floats to the level position of the liquid waste 21, and the float 5 becomes the liner L. ₄ When the top end portion of the float 5 is reached, the stop valve 9a is pushed up by the top end surface 5b1 of the float 5, and the suction passage 20 is closed. ₄ The suction pressure inside stops.
[0067]
In this way, before the entire liner L is filled with the liquid waste 21, the suction of the liquid waste 21 is automatically stopped by the stop valve 9a operated by the float 5, and the air pump is sucked excessively into each liner L. There is no risk of malfunction.
[0068]
When the liner L is removed from the bottle M after use, the canister head 12 of the stand 2 is opened and one end of the connecting tube 15 is rotatably attached to the discharge port 8 provided in the lid 3 of each liner L. The other end portion is inserted into and connected to the suction port 7 provided in the lid 3, and the cap 24 previously installed in the lid 3 is attached to each liner L as shown in FIGS. 6 (b) and 7 (a). After sealing the liner L over the exhaust port 9 provided in the lid 3, the liner L can be easily removed from the bottle M by pulling up the liner L using the handle 10 a of the holder 10. It can be discarded.
[0069]
The liquid waste 21 in the liner L is gelled and solidified by the water-absorbing material 6, and the liner L can be handled upright by the action of the bottom 4 of the liner L.
[0070]
Further, when the patient hose 14 or the connection pipe 15 is pulled out from the suction port 7 by the action of the rubber valves 14a1 and 15a1 of the valve hose 14 or the valve member 14a of the connection pipe 15, it remains in the patient hose 14 or the connection pipe 15. There is no risk that the liquid waste 21 that has fallen will sag.
[0071]
In this embodiment, four canister bottles E ₁ , E ₂ , E ₃ , E ₄ Are arranged in a straight line and the discharge port 8 provided in the lid 3 of each liner L and the suction port 7 provided in the lid 3 of the adjacent liner L are shown as an example. Three or more n (n ≧ 3) are connected and arranged on a straight line, and the first canister bottle E ₁ Liner L ₁ And a second canister bottle E ₂ Liner L ₂ The second canister bottle E is connected to the suction port 7 provided in the lid 3 ₂ Liner L ₂ Outlet 3 provided in the lid 3 and the third canister bottle E ₃ Liner L ₃ The suction port 7 provided in the lid 3 of the _n-1 Canister Bottle E _n-1 Liner L _n-1 Outlet 8 provided in the lid 3 and the nth canister bottle E _n Liner L _n What is necessary is just to comprise and connect with the suction port 7 provided in the lid | cover 3 of this.
[0072]
According to the above configuration, the canister bottle E is the first canister bottle E. ₁ To nth (n ≧ 3) canister bottle E _n All canister bottles E can be seen from one direction by arranging them in a straight line in the order of, and the liquid waste 21 is the first canister bottle E in the order of arrangement of the canister bottles E ₁ To nth canister bottle E _n Therefore, the user of the processing apparatus can easily check how much storage capacity is available.
[0073]
Further, the canister bottle E is composed of a bottle M as an outer container, and a liner L as an inner bag which is accommodated in the bottle M and has a water absorbent material 6 as a coagulant inside. 21 can be solidified in the liner L, and the entire liner L can be disposed of, so that a sanitary treatment apparatus can be obtained.
[0074]
Further, since the liner L of the canister bottle E has the float 5 having a specific gravity smaller than 1 and holding the water-absorbing material 6 on the inside thereof, the float 5 is always maintained at the position where it floats on the gas-liquid interface. By confirming the position of the float 5, the liquid level of the liquid waste 21 can be confirmed from the outside, and the user can surely confirm the use state of the canister bottle E and the remaining allowable capacity.
[0075]
In the above embodiment, the annular body 5a, the cup portion 5b, and the fixing ring 23 of the float 5 are made of polypropylene having a specific gravity smaller than 1. However, the material is not limited as long as the specific gravity of the float 5 is smaller than 1. .

【The invention's effect】
Since the present invention has the above-described configuration and operation, it is easy to visually recognize the internal volume even when the liquid waste collection capacity is increased, and the sucked liquid waste can be solidified more quickly.
[0080]
That is, the canister bottles are arranged in a straight line in the order from the first canister bottle to the nth (n ≧ 3) canister bottle, so that all the canister bottles can be seen from one direction, and the liquid waste canister Since the first canister bottle to the nth canister bottle are accommodated in the order in which the bottles are arranged, the user of the processing apparatus can easily check how much accommodation capacity is available.
[0081]
Further, when the canister bottle is composed of an outer container and an inner bag housed in the outer container and having a coagulant inside, the liquid waste is solidified in the inner bag, It can be disposed of and can be a sanitary treatment device.
[0082]
Further, when the inner bag of the canister bottle has a float having a specific gravity smaller than 1 and holding the coagulant inside, the float is always maintained at the position where it floats at the gas-liquid interface. By confirming the above, the position of the liquid level can be confirmed from the outside, and the user can surely confirm the use state of the canister bottle and the remaining allowable capacity.
[0083]
Also, when liquid waste is aspirated, the float with a specific gravity of less than 1 is always located at the gas-liquid interface of the liquid waste, and the water-absorbing material is always diffused to the newly aspirated liquid waste. The liquid waste can be solidified quickly and effectively.
[0084]
In addition, when the suction is once stopped and then suctioned again, the coagulation can be rapidly advanced, and the float is always at the gas-liquid interface, so that it also has a function as a level gauge indicating the internal volume. It can be made. Moreover, since the structure is simple, the manufacturing cost is low.
