Description

[Detailed description of the device] This device can store sterilized gauze, towels, etc., and prevents contaminated air from entering from the outside when opening or closing the lid to take them out. This invention relates to a storage device for sterilized products that prevents as much of the problem as possible.

2. Description of the Related Art As a sterilized material storage device used in hospitals and the like, for example, one shown in FIG. 1 is known.

In FIG. 1, 1 is the main body of a container for storing sterilized products, and the main body 1 is covered with a lid plate 2 to seal it tightly.

A hinge 3 is attached to one end of the cover plate 2, and a hanging ring 4 is attached to the center of the upper surface.

Then, the upper end of the hanging ring 4 is suspended from the tip of the arm 5, and by stepping on a footboard 6 attached near the floor, the tip of the arm 5 is lifted up, and the upper end of the arm 5 is lifted up via the hanging ring 4 using the hinge 3 as a fulcrum.
I try to open it by lifting it.

After taking out sterilized gauze, towels, etc. stored in the main body 1, when the foot is removed from the footboard 6, the lid plate 2 descends under its own weight and closes naturally.

By the way, in this case, when the cover plate 2 is opened, the space between the main body 1 and the cover plate 2 rapidly expands, and the space suddenly becomes negative pressure, drawing in surrounding air and causing the main body to open. This causes turbulence within 1.

For this reason, even if the air inside the main unit 1 is cleaned and sterilized items are stored there, the surrounding contaminated air will be drawn in, filling the inside with contaminated air and contaminating the items inside. be.

In particular, when the lid plate 2 is opened, most of the top surface of the main body 1 is opened, so that falling bacteria, so-called 1 falling bacteria, fall into the main body 1.

Conversely, when closing the cover plate 2, the main body 1 and the cover plate 2 are
As the space between the main body 1 and
The air between the top end and the lid plate 2 is pushed into the main body 1, causing turbulence between it and the air inside the main body 1,
The inside of the main body 1 is rapidly contaminated.

Therefore, even if you store sterilized items, even if you can take out the first item in a clean state, you will have to use the second item that is already contaminated.

The object of this invention is to provide a sterilized material storage device that can prevent contaminated air from flowing into the container as much as possible.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 2 is a partially cutaway perspective view showing one embodiment of this invention, and 10 is a base.

At the four lower corners of the base 10 are wheels 11, 11, 11, respectively.
．． 11 is installed.

A support 12 is erected vertically on the top surface of the base 10, and the support 1
A curved plate 13 curved in an arc shape is attached to the upper end of 2.

Two L-shaped notches 14 are formed at the upper end of the curved plate 13.

These notches 14, 14 are used to attach the separate main body 15, which will be explained with reference to FIG.

That is, the main body 15, which accommodates sterilized items therein, has a cylindrical shape and has an outer shape that matches the curved surface of the curved plate 13.

Then, fix two clasps 16 to the back of the main body 15,
These clasps 16.16 are inserted into the notches 14.1 of the curved plate 13.
The main body 15 can be attached to the curved plate 13 by slightly shifting the main body 15 in the horizontal direction while fitting it into the curved plate 13.

As is clear from FIG. 4, which shows the portion of the main body 15 from the front side in the state shown in FIG. It is said that

A short rotating shaft 19 is rotatably supported in the center of the side plate 18 on one side of the main body 15, and the inner end of the fan-shaped side plate 21 of the lid 20 is attached to the inner end of the rotating shaft 19, and Shaft 19 and lid body 2
0 so that they rotate together.

A short rotation shaft 22 is also spanned between the inner end of the side plate 21 on the other side of the lid body 20 and the center of the side plate 18 on the other side of the main body 15.

That is, the lid body 20 is rotatably supported relative to the main body 15 by the left and right rotation shafts 19 and 20.

The lid plate 23 on the front side of the lid body 20 has an arc shape centered on the rotation axis 19° 22, and is sized to just close the opening 17 of the main body 15.

When rotating about the rotation axis 19.22, the inner surface of the main body 15 is slid.

A rotating disk 24 is attached to the outer end of the rotating shaft 19, and two stoppers 25, 25 are attached to the inner surface of the rotating disk 24 at an angle of about 120 degrees.

A stopper 26 is also installed below the side plate 18 of the main body 15 while being located between the stoppers 25, 25.

At the position where the stopper 26 hits the upper stopper 25, the lid plate 23 of the lid body 20 closes the opening 17 of the main body 15, and at the position where the stopper 26 hits the lower stopper 25, the lid plate 23 closes the opening 17. I'm trying to keep it open.

A stopper 27 is attached to one location on the outer surface of the rotating disk 24.

As shown in FIG. 2, two levers 28.28 are rotatably mounted near the lower end of the support column 12, and a step plate 29 is mounted on the front end of the levers 28.28.

Further, a rod 30 is attached to the rear end of the levers 28, 28.

A support plate 31 is installed vertically near the lower end of the support column 12,
The rear end of a lever 32 rotatably attached to the support plate 31 and the upper end of the rod 30 are connected.

The lower end of a spring 33 is connected to the front end of the lever 32, and the lower end of a long rod 34 is connected to the upper end side of the spring 33.

The lower end of a spring 35 whose upper end is attached to the support column 12 is attached to the rod 34 to bias the rod 34 upward.

The upper end of the rod 34 is attached to a lever 36 attached near the upper end of the column 12 with one end as a fulcrum.

A lower end of a rod 37 is connected to the other end of the lever 36, and a U-shaped notch 38 is formed at the upper end of the rod 34.

(See Figure 3) The rerod 37 and the rotating disc 24 are connected by fitting the notch 38 into the stopper 27 of the rotating disk 24, and by removing the notch 38 from the stopper 27. We are trying to break the connection.

Attach the upper end of another short rod 39 to the lever 36,
The lower end of the rod 39 is attached to one end of a very short lever 40.

The other end of the lever 40 is attached to the upper end of a rod 41, and the lower end of the rod 41 is attached to an air cylinder 42 attached to the support column 12.
It is inserted inside.

Inside the main body 15, a hand towel for wiping hands after washing is stored in a sterile state and in a state where it can be taken out immediately. This will be explained with reference to FIGS. 6 and 7.

FIG. 5 is a perspective view of the main body 15 seen from slightly below, and FIGS. 6 and 7 are sectional views, respectively.

A support plate 43 is attached within the main body 15, and a holder 45 is rotatably attached by a hinge 44 attached to one end of the support plate 43.

The holder 45 has the shape of a rectangular parallelepiped with a hollow box inside, and is supported by the support plate 43 so that it is slightly tilted forward when stored in the main body 15.

The holder 45 is provided with an opening 46 diagonally downward toward the front, and is also opened on the side to form an entrance/exit 47.

As shown in FIG. 5, when the holder 45 is rotated about the hinge 44, the entrance/exit 47 of the holder 45 faces forward and diagonally downward.

A peephole 48 is formed in the upper surface of the holder 45.

A stopper plate 49 shaped like a leaf spring is attached inside the main body 15 so that the spring acts in the direction of the hole 45, and a protrusion 50 is formed in the middle of the stopper 49.

When the holder 45 is rotated using the hinge 44 as a fulcrum and pushed into the main body 15, when the edge of the rear plate of the holder 45 passes through the protrusion 50 of the stopper plate 49 while pushing it apart, the spring force of the stopper plate 49 causes the holder 45 to be pushed into the main body 15. It returns to its original position and the protrusion 50 stops the holder 45.

When you want to rotate the holder 45 forward and diagonally downward,
When the stopper plate 49 is expanded outward, the protrusion 50 comes off and the holder 45 rotates.

The separate storage box 21 can be inserted into or taken out from the entrance 47 of the holder 45.

The storage box 51 has a box-shaped structure as shown in FIGS. 5, 6, and 7, with a long slit in the horizontal direction in the front, and two sheets are placed facing each other along the slit. The tongue pieces 52, 52 are attached.

The tongue pieces 52, 52 are made of plastic sheets and coated with an antistatic agent.

A peephole 53 is provided at one location on the top surface.

Inside the storage box 51, a large number of hand towels 54 are folded and stored one on top of the other.

The hand towel 54 is made of woven fabric, non-woven fabric, paper, or the like.

As shown in FIG. 6, a take-out piece 55 for taking out the first selvage of the hand towel 54 is disposed at the forefront when it is not in use.

Further, at the end of the folded and stacked hand towels 54, a plate-shaped weight plate 56 is stacked.

The items shown above are used as follows.

As shown in FIG. 8, when the footplate 29 is stepped on, the lever 28.2
8 rotates to lift the rod 30, and rotates the lever 32 to pull down the spring 33.

At first, the spring 33 stretches itself slightly and then moves toward the rod 3.
The rod 34 is gradually pulled down, and then the rod 34 is further pulled down while contracting back to its original state.
This provides a buffering effect so that the rod 34 does not fall suddenly even if you step on it strongly.

Then, when the rod 34 descends, the lever 36 is rotated downward and the rod 37 is pulled down.

The rod 37 rotates the rotating disk 24, and the lid body 20 is rotated upward via the rotating shaft 19.

The lid 20 stops rotating when the lower stopper 25 attached to the inner surface of the rotating disk 24 hits the stopper 26 attached to the side plate 18 of the main body 15. The opening 17 has been removed and is completely open.

The state in which the mouth portion 17 is opened is shown in FIGS. 8 and 9, and is particularly clearly shown in FIG. 9, which is a perspective view of the main body 15 viewed from the front side.

When the lid body 20 is rotated upward as described above, the lid plate 23, which has an arc shape centered on the rotation axis 19.22, rotates around the rotation axis 19.22. Since it moves in an arc, it just cuts through the air.

Therefore, irrespective of the movement of the cover plate 23, there is almost no change in the air pressure inside or outside the main body 15, and therefore the air inside the main body 15 hardly flows out or flows into the main body 15.

A storage box 51 containing sterilized hand towels 54 is stored in the holder plate 45 in the main body 15, but contaminated air from the surroundings flows into the main body 15 and contaminates the hand towels 54. There is little to do.

Furthermore, when the opening 17 of the main body 15 is open, it is open over an angle range of about 120 degrees from approximately the lower end position of the main body 15, and the upper part of the main body 15 is almost covered.

By the way, contamination is relatively often caused by bacteria falling under their own weight, so-called 1-drop bacteria.
By covering most of the upper part of 5, contamination by falling bacteria can be prevented.

After opening the opening 17 of the main body 15, the hand towel 54 is taken out.As shown in FIG. When the piece 55 is pulled out, the first piece of the hand towel 54 protrudes, and at the same time, the tongue pieces 52, 52 also protrude facing each other, sandwiching the tip of the hand towel 54 and making it stand up (see FIG. 7).

When wiping your hands after washing before surgery etc.
The hand towels 54 are taken out one by one from the slits in the storage box 51 fitted in the holder 45 to wipe the hands.

The reason why the weight plate 56 is placed inside the storage box 51 is to press the stacked hand towels 54 toward the slit side, thereby making it easier to take out the hand towels 54.

The tongue pieces 52, 52 are provided oppositely on both sides of the slit in order to make the tip of the hand towel 54 stand up and easy to take out, and to prevent external bacteria from entering the storage box 51.

Further, the reason why the tongue pieces 52 52 are coated with an antistatic agent is to prevent the tongue pieces 52 , 52 from attracting surrounding dust when charged.

The peephole 48 was made in the hole goo 45 and the peephole 53 was made in the storage box 51.
This is to make it possible to see the remaining amount of 4 from the outside.

Immediately after taking out the hand towel 54 from the storage box 51, the user removes his or her foot from the footboard 29, causing the spring 35 that has been extended to contract and lift the rod 34 that has been lowered.

When the rod 34 rises, the lever 36 is rotated upward,
Raise the rod 37.

Then, the rotating disk 24 is rotated in the original direction, and the rotating shaft 1
9, the lid body 20 is rotated downward.

When the lid 20 begins to rotate downward, it tries to rotate all at once due to its own weight, but when the lid 20 rises, the rod 41 in the air cylinder 42, which has been rising together, is rotated. Moving shaft 19, rotating disk 24, rod 37, lever 3
6. Even if a downward force is suddenly applied via the rod 39 and the lever 40, the rod 41 can only descend gradually due to the air inside the air cylinder 42, and therefore the bottom of the lid 20 Rotation in this direction will be slow.

That is, the mechanism consisting of the rod 41 and the air cylinder 42 is intended to act as an air cushion.

When the lid body 20 slowly rotates downward, the lid plate 23 slowly closes the opening 17 of the main body 15 while moving in an arc around the rotation shafts 19 and 22.

Therefore, even when the opening 17 is closed, there is little possibility that contaminated air from outside the main body 15 will flow into the main body 15.

When the hand towels 54 in the storage box 51 are completely exhausted, by opening the opening 17 of the main body 15 and pushing the stopper plate 49 outward, the protrusion 50 will come off the edge of the hole goo 45 and the hole goo 5 will release the hinge 44. It rotates diagonally forward and downward as a fulcrum, and its entrance/exit 47 is connected to the opening 1 of the main body 15.
It protrudes forward and diagonally downward from 7.

Here, the storage box 51 is removed from the entrance 47 and a new storage box 51 is inserted (see FIG. 5), the hole goo 45 is rotated back to its original position and stopped by the protrusion 50 of the stopper plate 49, and the main body 15 is opened again. It is sufficient to close the opening 17.

Although one embodiment of this invention has been shown above, the invention is not limited to the above embodiment.

For example, although the lid body 20 is actuated by stepping on the footboard 29, the transmission mechanism for transmitting the power between the footboard 29 and the lid body 20 is not limited to the one illustrated.

Furthermore, although the opening 17 is opened and closed by stepping on the footboard 29, the opening 17 may be opened and closed by moving various parts of the slender body.

It may be electrically opened and closed using a motor.

Attach the hole goo 45 inside the main body 15 and remove the hole goo 45.
Although the storage box 51 containing the hand towel 54 is fitted inside the main body 15, there are many other ways to store the hand towel 54 inside the main body 15.

In addition, although a sterilized hand towel 54 is stored in the main body 15, other sterilized gauze, towels, scalpels, tweezers, etc. may also be stored, and any of these may be stored. It is up to you whether you want to store it in this way.

As is clear from the above, in the sterilized material storage device according to this invention, since the lid plate 23 opens and closes the opening 17 while moving in the direction along the opening 17, the lid plate 23 When the opening 17 is opened and closed, there is almost no change in the atmospheric pressure inside the main body 15.

Therefore, since there is almost no inflow of contaminated air from the outside, the sterilized materials stored in the main body 15 are hardly contaminated.

The main body 15 is cylindrical and the opening 17 is provided in the cylindrical part, and the cover plate 23 of the cover body 20 is attached coaxially with the cylinder and reciprocated in an arc around the axis of the cylinder. Since the opening 17 is opened and closed, the locus of movement of the cover plate 23 can be kept within the same cylinder, making the whole structure compact, and the opening and closing mechanism can be made simple.

Since the opening 17 is formed in a position that almost avoids the upper part of the main body 15, even when the opening 17 is opened, most of the upper part of the main body 15 is covered, and fallen bacteria will fall into the main body 15. Not at all.
