Description

      The present invention relates to a simple isolation room for beds for preventing dialysis patients from being infected with new or seasonal inferenza during prolonged dialysis or isolating suspected infection patients. .

The treatment of patients infected with the new Inferenza is to maintain a negative pressure in the room, and use a high-performance HEPA filter (the HEPA (hepa) based on JIS) is a particle with a rated flow rate and a particle size of 0.3 μm. It is ideal to perform in a negative pressure isolation room where the particles are sterilized and released outside the room.

However, since this negative pressure isolation room is expensive (650,000 yen), purchasing several units at a general hospital or dialysis clinic is costly and cannot be easily installed.

In addition, when the season is off, the negative pressure isolation room cannot be applied to other applications, and the hospital staff (nurse) cannot be disassembled and stored.

  The present invention is a simple isolation room for a bed made by covering a frame of a stretchable aluminum pipe with a square bottom bag made of polyethylene film from above. A commercially available air purifier (ozone type, plasma type, with humidifier) is installed in the sick room to disinfect the room.

  First, compared to negative pressure isolation rooms, the cost is about 1/4 to 1/2 and the cost merit is great. Next, assembly and disassembly are easy and storage is compact. Easy assembly and disassembly by hospital staff (can be assembled in about 15 minutes by two nurses) without requesting a specialist. Therefore, when the season is off, it can be disassembled and stored in the bag and stored under the bed.

  In terms of performance, depending on the performance of commercially available air purifiers, for example, when an ozone air purifier is installed in a room, airborne bacteria in the air can be removed with ozone using pre-filters and HEPA filters. Sanitize without making it. Also, ozone keeps the inside of the air cleaner clean and prevents secondary infection. Accordingly, prevention of inferenza and the like is also effective.

Furthermore, another excellent point of the present invention is that ozone fumigation such as bet can be safely performed in a hospital room where patients are present. The most important point in ozone fumigation such as betting is to prevent ozone gas from leaking. The present invention resides in that the bed is doubly surrounded by a thick (100 μm) polyethylene film.

The most scary of nosocomial infections is said to be MRSA (methicillin-resistant Staphylococcus aureus), and is generally said to be a pathogen that appears due to abuse of antibiotics. When the bacterium infects and develops in a patient with reduced immunity, most antibiotics are ineffective and treatment is difficult.
This is said to be partly due to insufficient disinfection of the bed. Therefore, since ozone can be sterilized by fumigation, it will provide a great contribution to future medical care.

The first configuration of the present invention related to the simple isolation room for betting is that a plastic film is formed on a frame formed by removing one ridge line out of four ridge lines in contact with the floor surface, out of a frame composed of ridge lines of a rectangular parallelepiped. In a simple isolated hospital room for bets made by covering a square-bottomed bag made from above, pipes in the vertical, horizontal, and height directions of the framework that controls the ridgeline, where stretch adjustment pipes are used where length adjustment is necessary, And the relationship between the vertical, horizontal and height dimensions of the frame and the vertical, horizontal and height of the square bottom bag is about 5 cm larger than the vertical and horizontal dimensions of the vertical frame. On the contrary, the height of the square bottom bag is characterized by being about 50 cm shorter than the height of the frame.

According to this configuration, when used as a simple isolation room for a bed, if the gap between the end face of the square bottom bag and the floor surface is adjusted to 0 by adjusting the height-extensible telescopic pipe to be low,
The inside and outside of the room will be blocked and isolated. Furthermore, if the end face part of the square bottom bag is bent to be bent, the area in contact with the floor surface is increased and the sealing effect is further improved. In practice, it is optimal to bend about 5 cm to 10 cm. . What is necessary is just to treat an infiltenza infected person in this state.

    Also, when the infected person is discharged and disinfects the bed that has been used so far, as described above, the gap between the end face of the square bottom bag and the floor surface should be 0, and ozone fumigation should be performed.

    On the other hand, for example, in the case of ozone fumigation for the entire room of a four-person room (a large room with four beds), the height of the telescoping pipe in the height direction should be increased until the upper part of the frame touches the ceiling. The gap between the end face of the square bottom bag and the floor surface is maximized. For example, if the height from the floor to the ceiling is 2.5 m, the gap is 0.4 m when the height of the square bottom bag is 2.1 m, and there is no obstacle to ozone fumigation in the entire room. It's a mess.

    In addition, it is more effective if the larger side wall of the wrap-type doorway is lifted and bent into the frame on the upper surface, and then the height-expandable pipe is raised and raised so that the upper part of the frame is in contact with the ceiling. Is.

The second configuration of the present invention relating to the simple isolation room for betting is that the ridge line of the substantially rectangular parallelepiped shape is removed from one of the four ridge lines in contact with the floor surface. One horizontal bar (expandable pipe) is formed between the central part of the short ridge line facing the central part of the ridge line.

    According to this configuration, when the square bag is constructed on the frame, the height of the frame is assembled in a minimum state of about 1.5 m (a state when the expansion and contraction pipe is contracted).

    First, when the square bottom bag is put on the frame, the two corners on the entrance / exit side are temporarily positioned, and then the remaining square bag is placed on the horizontal bar at the top of the frame. Next, it is gently pushed and moved to the opposite entrance side, and the two corners on the opposite entrance side are aligned and covered.

If attached in this way, it can be easily done by two hospital staff (nurses). It can be installed smoothly without being cut or torn when the square bag is caught.

In addition, numbers 1, 2, 3, 4 and magic ink are written in advance at the four corners of the bottom of the square bottom bag, 1 and 2 indicate the entrance / exit side, and 3 and 4 indicate the direction of the counter entrance / exit side. If this is done, there will be no mistakes in the mounting direction, and mounting can be done efficiently.
Adjust the height of the telescopic pipe in the height direction to an appropriate height (2.1m).

        The horizontal bar in the upper center of the frame not only serves to reinforce the frame, but also serves as a loading area when constructing a square-bottom bag. Therefore, it has the convenience that a bet can be easily put in and out.

    The third configuration of the present invention related to the simple isolation room for betting is that one of the four ridge lines in contact with the floor surface is removed from the frame composed of ridge lines of a rectangular parallelepiped, and the side surface side of the removed ridge line A plurality of wrap-type entrances and exits for square bottom bags

    According to this configuration, there is no pipe on the floor surface below the wrap type entrance / exit of the square-bottom bag, so that it becomes barrier-free, and a patient, nurse, doctor, or the like trips over when entering or exiting. There is nothing. By removing one of the ridges in contact with the floor surface, the strength is weakened. However, the weight of the square bottom bag is 2 kg, the weight of the aluminum pipe frame is about 9 kg, and the total weight is 11 kg. It will spread somewhat if you apply extra power, but it will not cause any practical problems.

    In addition, since the wrap type entrance / exit uses a polyethylene film thickness of 100μ, it hangs down under moderate weight and has moderate tension. Since it closes at a speed, the opening and closing operation can be performed smoothly.

    In addition, when entering and exiting the bed from the wrap-type entrance, if you turn over the large side wall surface of the entrance, lift it up and fold it back, the entrance will open, leaving it on the horizontal bar at the top center of the frame. Bets can be put in and out.

    Therefore, it is normal for humans to enter and exit from the left and right laps, and a lap allowance of 500 cm to 600 cm is appropriate. When a bed is put in and out, the large side wall of the entrance is placed on the horizontal bar at the top of the frame. If placed, the frontage at the center is 800 cm to 1000 cm, which is approximately the same size as the width of the bed.

Ozone fumigation test results-part 1
After placing staphylococci in a petri dish in a simple isolated hospital room for bed with a wrap-type doorway and filling the ozone concentration with 0.1 ppm and 0.2 ppm for 3 hours each with an ozone generator, 24 As a result of being left as it is for 1 hour, it was completely sterilized. 2) There was no leakage of ozone. (Three nurses judged the outside of the room by the presence or absence of the smell of ozone.) From the above results, it was confirmed that polyethylene film 100μ, single-bottom bag structure, and wrap-type entrance and exit did not leak ozone. did it.

    The fourth configuration of the present invention relating to the simple isolation room for betting is that a vertical bar (extensible pipe) is formed on each side of the square bottom bag for ozone to clamp the square bottom bag and vertical bar for ozone. The upper end surface of the height adjustment knob of the frame is used as a stopper for the clamp.

According to this configuration, a vertical bar is put on each side of the ozone bottom bag, and the ridge line on the top of the ozone square bag becomes a rod-like straight line, so the lower ridge line is also the weight of the polyethylene film. , And can be cleaned following the ridgeline substantially above, so that the space of the square bottom bag for ozone can be reliably formed. In addition, the film on the floor of the bottom bag for ozone is slightly wavy, but it can be made almost flat so that when placing a bet, the bed caster is stored in place without being caught or cut by the film. It can be done.

    Next, gather around the central part of the opening of the square bottom bag by hand, pull out the power cord of the ozone generator from the middle, and complete the preparation if tied with a magic band,

Test results of ozone fumigation-Part 2
As a result of placing staphylococci in a petri dish in a simple isolated hospital room for bed with a wrap-type doorway and filling the ozone concentration with 0.3 ppm for 3 hours with an ozone generator, and leaving it as it is for 24 hours, 1) It was completely sterilized. 2) There was no leakage of ozone. (Three nurses judged the outside of the room by the presence or absence of ozone odor.) From the above results, it was confirmed that there was no ozone leakage even at the double bottomed bag structure and the wrap-type entrance with a polyethylene film 100μ. did it.

    In this way, as shown in the above two test results, ozone fumigation of the bed did not leak ozone even with a single square bottom bag and obtained good results, but if the structure was further doubled, Reliability is greatly improved.

    The fifth configuration of the present invention related to the simple isolation room for betting is that the four ridge lines in the height direction are removed from the frame composed of the ridge lines of the rectangular parallelepiped, and instead, from the center of the short ridge line at the top. A vertical bar (expandable pipe) was installed in the height direction, one each toward the lower part, and one of the longer ridge lines in contact with the lower floor surface was removed, resulting in a substantially U-shape. It is characterized by.

    According to this configuration, since the number of ridge lines constituting the skeleton is two less than the ridge line skeleton having a substantially rectangular parallelepiped shape, it is inexpensive and easy to assemble. In addition, since there are two frames corresponding to the ridgeline in the height direction across the bed, the height adjustment is easy.

    A sixth configuration of the present invention relating to a simple isolation room for a bed is characterized in that wrap-type doorways are formed on both sides of the long ridge line side of a substantially rectangular parallelepiped square bottom bag.

    According to this configuration, since one of the longer ridge lines out of the ridge lines in contact with the floor surface of the frame is removed, the wrap-type entrance is inevitably on the long ridge line side in order to make the barrier free. Therefore, if a wrap-type doorway is formed on both side surfaces on the long side of the square bottom bag, either one can be used.

In Example 2, the double structure of the polyethylene film in the square bottom bag when ozone fumigation disinfects is a method of covering both from the top, and the whole bed cannot be surrounded, but the test result of ozone fumigation disinfection Was the same as the above-mentioned test result and was good.

    As described above, the simple isolation room for a bed according to the present invention is a simple tent made by covering a frame of a stretchable metal pipe with a square bottom bag made of a polyethylene film, and commercially available air therein. An air purifier is installed to disinfect the room. Even if the new Inferenza is in a pandemic state, hospital staff (nurses) can easily assemble and install around the bed, making emergency responses possible. Also, once the Inferenza epidemic is over and the season is off, it can be applied to bed ozone fumigation, saving the hassle of busy nurses. Furthermore, by double-enclosing the bed with a polyethylene film, ozone fumigation such as a bed can be safely performed even in a hospital room.

    The best mode for carrying out the present invention will be described below with reference to the drawings. 1 to 9 show the first embodiment, and FIG. 10 shows the second embodiment.

FIG. 1 shows a simple isolation room 1 for a bed according to Example 1 of the present invention,
The frame 2 is composed of a metal pipe (aluminum pipe or stainless steel pipe) and a square bottom bag 13. It is an external view when the bed 14 and the dialysis device 18 are installed in the hospital room 1.

FIG. 2 shows a framework 2 of a simple isolation room 1 for betting according to the first embodiment of the present invention.
The skeleton 2 is formed by connecting a long ridge line 3 and a short ridge line 4 in contact with a lower floor surface by a triaxial joint 9 and arranging them in a substantially U-shape. In order to make the front entrance / exit side barrier-free, one ridge line is removed. An L-shaped joint 11 is coupled in front of the longer ridgeline 4 in contact with the floor surface.

    Since the longer ridgeline 3 and the shorter ridgeline 4 that are in contact with the floor are made of telescopic pipes, they are adjusted to a predetermined length by the length adjustment knob 12.

  Next, in assembling the upper part of the frame, the short ridge line 6 is adjusted to a predetermined length and arranged parallel to the lateral direction. Next, the longer ridgelines 7 and 8 are adjusted to a predetermined length and arranged parallel to the vertical direction. Next, the long ridgeline 7 at the center is attached to the T-shaped joint 10. Similarly, the long ridgeline 8 on both sides is attached to the triaxial joint 9. When the frame upper group is completed as described above, place it on the floor near the bed.

    Next, the ridgeline 5 in the height direction adjusted to a predetermined length is inserted and attached to the lower set of the previously assembled frame.

  Finally, the previously assembled frame upper group is inserted into the upper part of the ridge line 5 in the height direction and screwed.

    In consideration of when reassembling after disassembly, the color of the screw to be assembled and disassembled in the hospital is black, so that mistakes in assembling and disassembling can be prevented and work can be performed efficiently.

When constructing the square bottom bag 13 shown in FIG. 3 on the frame 2, the height of the frame is assembled in a minimum state of about 1.5 m (a state when the expansion pipe is contracted).
First, when the square bottom bag 13 is put on the frame 2, the two corners on the entrance / exit side are temporarily positioned, and then the remaining square bottom bag 13 is placed on the upper horizontal bar 7. Next, it is gently pushed and moved to the counter-entrance side, and the two corners on the counter-entrance side are aligned and covered.
If attached in this way, it can be easily done by two hospital staff (nurses). At the time of attachment, the square bottom bag 13 can be smoothly attached without being caught or broken.
In the four corners of the bottom bag 13, numbers 1, 2, 3, and 4 are written in advance with magic ink, 1 and 2 indicate the entrance / exit side, and 3 and 4 indicate the counter entrance / exit side. If it is, it will be possible to mount efficiently without any mistakes in the mounting direction.
Adjust the height of the telescopic pipe in the height direction to an appropriate height (2.1m).

        The horizontal bar 7 at the upper center of the skeleton not only serves to reinforce the skeleton, but also serves as a loading portion when the square bottom bag 13 is constructed, and when the bed 14 enters and exits from the wrap-type entrance 19, the entrance 19 If the side wall 20 having a large size is lifted and folded, it will be placed, so that the bed 14 can be easily put in and out.

    The vertical bar used in the ozone fumigation square bottom bag shown in Fig. 3 can also be used as a curtain of colorful colors made of nylon resin that does not absorb water or polyethylene resin, and substitutes for a screen that protects patient privacy. It will also be. (Not shown)

    FIG. 4 is a perspective view of the bet simple isolation room 1 according to the first embodiment of the present invention and a square bottom bag for ozone fumigation before attachment. The installation direction of the square bottom bag for ozone fumigation is the same as the above-mentioned square bottom bag, and if the numbers are written in black magic on the opening and bottom, there is no mistake in installation and it is efficient.

    Vertical bars 16 (expandable pipes) are formed on both sides of the ozone fumigation square bottom bag 15, and the ozone square bottom bag 15 and the vertical bar 16 are sandwiched together by a clamp 17, and the frame 2 The end face of the height adjustment knob 12 is a stopper of the clamp 17.

FIG. 5 shows that the vertical ridge line 16 is put on each side of the ozone square bottom bag 15 and the ridge line above the ozone square bottom bag 15 becomes a rod-like straight line. Since it hangs down by the dead weight of the polyethylene film and can be cleaned following the ridgeline substantially above, the space of the ozone square bottom bag 15 can be formed reliably. Also, the film on the side surface 22 of the ozone bottom bag 15 on the floor surface is slightly wavy, but can be made almost flat, so that when the bed 14 is put, the caster 23 of the bed is placed on the side wall portion of the ozone bottom bag. The film 22 can be stored in a predetermined position without being caught or cut.
Next, the surroundings of the opening 21 of the square bottom bag for ozone are gathered together in the center, and the power cord of the ozone generator is pulled out from the center and tied with a magic band to complete the preparation.

FIG. 10 shows the skeleton 2 and the square bottom bag 13 of the simple isolation room 1 for betting according to the second embodiment of the present invention. Since there are two ridge lines 5 in the height direction, the height can be easily adjusted. Since the wrap type entrance / exit 19 of the square bottom bag 13 of Example 2 is provided on both sides of the longer ridge line side of the substantially rectangular parallelepiped shape, when the bed is placed in the hospital room, it may be placed at either the left or right corner. It has the advantage that such a doorway can be used.
