Description

  The present invention relates to a mattress cleaning and disinfecting apparatus and a mattress cleaning and disinfecting method.

Traditionally, mattresses have been used for beds in hospitals and general households, but mattresses in hospitals and elderly facilities are used by unspecified large numbers of people. It is required to keep. Of course, it is desirable to keep the mattress clean for comfortable use even in a mattress in a general household. Nevertheless, since the mattress is difficult and time-consuming to clean, it is usually used for a long time without cleaning the mattress. As a result, various germs and odors such as fleas and ticks adhere to the surface of the mattress or invade the inside of the mattress, resulting in a very unsanitary situation.
In addition, rental products may be used for special mattresses such as special mats and medical mats. In this case, incompletely washed mattresses will move from one end to the other, so that infections may be transmitted. May harm the health of users.

Under such circumstances, in recent years, there has been an increase in interest in nosocomial infections of MRSA, zero virus, Pseudomonas aeruginosa, etc., and there has been a movement to periodically clean and disinfect such mattresses.
However, if the mattress is to be washed and disinfected by hand, the mattress contains a lot of water and its weight increases significantly, which requires a great deal of labor and time by a plurality of human hands.

On the other hand, a small number of devices have been proposed so far that can wash the entire mattress and reduce the labor for mattress cleaning.
This conventional mattress washing apparatus can be roughly divided into two types. One is a type in which a plurality of mattresses are set in an arc shape along the inner periphery of the drum and are rotatable, and washing is performed while spraying washing water from a rotating shaft (for example, Patent Document 1). The other is a type in which a plurality of mattresses are similarly set in an arc shape along the inner periphery of the drum and are freely rotatable, and washing is performed while being immersed in cleaning water accumulated in the drum (for example, Patent Document 2).

  However, according to the conventional mattress washing device, it is difficult to sufficiently wash away the dirt attached to the mattress and the sterilized carcasses (mold, germs, ticks) etc. from the mattress. There has been a problem that the used washing water containing spilled filth etc. contaminates other mattresses again and causes secondary infection.

Therefore, the present invention has been made in view of the above-mentioned problems, and can sufficiently wash away filths adhering to / intruding into the mattress, dead bodies after sterilization (mold, various bacteria, mites), and preventing secondary infection. It is an object of the present invention to provide a mattress cleaning / disinfecting apparatus and a mattress cleaning / disinfecting method.

In order to solve the above problems, a mattress cleaning and disinfecting apparatus according to claim 1 accommodates mattresses facing each other and arranges and holds them at a predetermined inclination angle so as not to overlap each other. And a fountain unit having a nozzle that is provided above the mattress held by the holding unit and that ejects cleaning water. The first state is a state in which the mattress has the predetermined inclination angle, and the second state is the state in which the first state is turned upside down by the driving means. In the state 1 and the second state, the holding part is stopped, the washing water is ejected from the fountain part, and the washing water is allowed to flow down through the surface and the inside of the mattress. Bacteria were killed adhering Intrusion, a mattress washing and disinfecting apparatus that wash away mites, the predetermined inclination angle of the mattress to be held by the holding portion, and variable in accordance with mattress pollution degree This is the gist.

Further, the mattress cleaning and disinfecting apparatus according to claim 2 accommodates two mattresses facing each other and arranges them at a predetermined inclination angle so as to have a substantially C shape and a substantially inverted C shape in sectional view. A fountain having a holding portion to be held, a driving unit that can be rotated upside down by rotating the holding portion, and a nozzle that is provided above the mattress held by the holding portion and ejects cleaning water A holding portion is stopped in a state in which the mattress has a substantially C-shaped and a substantially inverted H-shaped cross-sectional view, and the cleaning water is ejected from the fountain portion so that the cleaning water is discharged from the mattress. The mattress cleaning / disinfecting apparatus is adapted to wash away dead bacteria and mites adhering to and invading the mattress by flowing down through the surface and the inside of the mattress , and a predetermined mattress held in the holding portion. of The oblique angle, and summarized in that the variable in accordance with mattress pollution degree.

The mattress cleaning and disinfecting apparatus according to claim 3 is the configuration according to any one of claims 1 to 2, wherein the predetermined inclination angle of the mattress held by the holding portion is 55 ° to the horizontal plane. The gist is 70 °.

According to a fourth aspect of the present invention, there is provided a mattress cleaning / disinfecting apparatus according to any one of the first to third aspects, further comprising discharge means for discharging the washed-down cleaning water, and passing through the surface and the inside of the mattress. The gist is that the used washing water is discharged through the discharging means without being circulated .

A gist cleaning and disinfecting apparatus according to a fifth aspect is characterized in that, in the configuration according to any one of the first to fourth aspects, a caster is provided on the grounding surface so as to be movable .

According to the present invention, the mattresses are accommodated facing each other, and each holding unit is arranged and held at a predetermined inclination angle so as not to overlap each other, and the holding unit is rotated to turn upside down. And a fountain part provided above the mattress held by the holding part and having a nozzle for jetting cleaning water, and the mattress has the predetermined inclination angle. One state is set as the first state, and the state in which the first state is turned upside down by the driving means is set as the second state. In the first state and the second state, the holding state is maintained. The washing water is ejected from the fountain and the washing water is allowed to flow through the surface and the inside of the mattress to wash away dead bacteria and mites adhering to the mattress. Since the mattress cleaning and disinfecting device is configured, the mattress cleaning and disinfecting that can sufficiently wash away the filth that adheres to and invades the mattress and the sterilized dead bodies (mold, various bacteria, mites), etc., and can prevent secondary infection. An apparatus and a mattress cleaning and disinfecting method can be provided.

The mattress cleaning / disinfecting apparatus according to the present invention includes a holding unit, a driving unit, and a fountain unit.
The mattress includes a mattress made entirely of a fibrous material, urethane, or the like, or a spring mattress having a built-in metal coil spring, and any mattress is included in the subject of the present invention. In particular, it can be effectively used for special mats and medical mats which are excellent in air permeability and water permeability but are expected to have a high degree of contamination. Among them, a corrugated structure formed by corrugating in the length direction using polyester fibers or the like is very effective. In addition, a high effect can be expected even when used for a sealed (low repulsion) mattress.
Further, when the cover is removed, the mattress, mold, bacteria, germs and the like are scattered when the cover is removed. Therefore, the mattress is set on the apparatus of the present invention while the cover is attached, and cleaning and disinfection are performed. When the dirt is remarkable, it is preferable to remove the cover and perform cleaning and disinfection of only the mattress.

The holding section is for holding and holding the mattresses one by one at a predetermined inclination angle so that the mattresses do not overlap each other. Preferably, the two mattresses are held at a constant interval. Is configured to be accommodated facing each other. As an arrangement mode of the mattress, a configuration in which the mattress is substantially parallel to each other is conceivable in addition to the mattress having a substantially C shape or a substantially inverted C shape in cross section.
Further, the holding unit is configured so that the mattress can be disposed and held at a predetermined inclination angle even after the holding unit is turned upside down by a driving unit described later.

From the viewpoint of disposing the mattress at a predetermined inclination angle, it is theoretically possible to hold only one mattress or three or more mattresses in a zigzag shape, but only one mattress. Then, the efficiency of cleaning is poor, and conversely, if three or more, the apparatus becomes too large, which is not appropriate. However, these aspects are not excluded.
The holding part has a structure through which washing water ejected from a fountain part, which will be described later, can easily pass, for example, a net-like, lattice-like, or porous structure, and a minimum skeleton so that the area covering the mattress to be accommodated is as small as possible. It is preferable to have a configuration consisting of

The driving means is configured to rotate the holding portion around the rotation axis and to be turned upside down while substantially maintaining the relative positional relationship between the two mattresses provided by the holding portion.
Thereby, for example, a mattress in a substantially C-shaped cross-sectional view is inverted by 180 ° to obtain a substantially inverted C-shaped cross-sectional view, and a mattress in a substantially inverted C-shaped cross-sectional view is inverted by 180 °. Thus, it is possible to obtain a substantially C-shaped state in cross-sectional view.
The rotation shaft may be provided in parallel to the length direction of the mattress or may be provided vertically. In the latter case, the washing water flowing out from one mattress at the time of rotation is not applied to the other mattress, and is particularly suitable for a mattress with high infectivity.
The driving means may be of any configuration as long as it can transmit the rotational force to the holding portion via the rotating shaft and can drive the holding portion to rotate, for example, a motor or a manual lever handle. Etc. can be used.

The fountain part is provided above the mattress held and accommodated by the holding part, and is for cleaning and disinfecting the mattress by ejecting cleaning water from above the mattress. The fountain part is provided with a nozzle for ejecting the wash water downward.
The amount of water flowing from the fountain is preferably 10-15 liters / minute. If the flow rate is less than 10 liters / minute, the amount of water will be too small and it will be difficult to flush out the dead bacteria and mites that have adhered to and invaded the mattress. Conversely, if the flow rate exceeds 15 liters / minute, Rebounding will occur and reduce the flowing water effect, which is not preferable.

Although clean water is used as the washing water, if necessary, clean water mixed with a disinfectant or disinfectant may be ejected from the fountain. Moreover, it is good also as providing the spout for exclusive use of the chemical | medical agent for disinfection separately from the washing water nozzle of a fountain part by making the supply path | route of the chemical | medical agent for disinfection into another system.

In the apparatus of the present invention, the first state is a state in which the mattress has the predetermined inclination angle (for example, a substantially C-shaped cross-sectional view), and the first state is turned upside down by the driving means. In the first state and the second state, the holding unit is stopped and the washing water is ejected from the fountain unit. Then, the washing water is allowed to flow through the surface and the inside of the mattress to wash away the dirt and the like attached to the mattress.
In the present invention, the mattress is washed in a state where the mattress has a predetermined inclination angle, so that the surface and the inside of the mattress adhere to and enter the filth, various germs, sterilized dead bodies (mold, germs, mites), etc. It is comprised so that it can wash away effectively.
In the present invention, since the cleaning is performed in both the first state and the second state, the entire surface of the mattress (the top, bottom, front, back, left and right) and the inside can be sufficiently cleaned. . It is also possible to drain the mattress in a very short time.

The predetermined inclination angle of the mattress accommodated in the holding unit is optimally configured to be 55 ° to 70 ° with respect to the horizontal plane. When the inclination angle is less than 55 ° and approaches flat, water permeability deteriorates and draining becomes insufficient. On the other hand, if it approaches 70 ° beyond 70 °, the mattress surface and the entire interior cannot be washed away.

There are no particular restrictions on the overall shape and size of the device of the present invention, forming material, etc., but for example, it is compact enough to enter a hospital elevator using materials with excellent weather resistance and durability such as stainless steel and FRP. If it is configured in size and the apparatus of the present invention is installed and used on the rooftop of a hospital, the flow line of the mattress can be shortened and the mattress after washing is immediately sun-dried (sunlight deodorization) It is also preferable.
In the embodiments described later, the outer shape of the apparatus of the present invention is mainly composed of only a frame, but a wall panel or a roof panel may be attached if necessary. However, in that case, it is preferable to provide a sterilizing gas supply means or the like in order to facilitate propagation of germs and the like.
In addition, a caster may be provided on the grounding surface of the apparatus so that the apparatus can be moved. In addition, the apparatus of the present invention is mounted behind a truck or van, and can be used by visiting a hospital or a general household as appropriate. it can.

  The mattress after washing is preferably sun-dried and sterilized by sunlight (ultraviolet rays). However, if necessary, the apparatus of the present invention may be provided with a drying function. In addition, a heater for supplying warm water as cleaning water, a warm air generating function, an exhaust function, and the like may be provided. Further, if a waterproof germicidal lamp is provided, maintenance is facilitated.

  The device of the present invention can be used to continue and use the mattress comfortably and safely. For example, when disposing of the mattress, if the apparatus of the present invention is used, it becomes possible to dispose of the contaminated mattress after appropriately washing and disinfecting it, which is preferable from the viewpoint of the waste treatment method.

The cleaning water is ejected only from the inwardly facing nozzle (53), and when it is arranged in an inverted C shape, the cleaning water is ejected from only the outwardly facing nozzle (53 '). ing.
Such a movable fountain unit (50) (50 ') is preferable because the uniform fountain amount and water pressure from the nozzles (53) (53') can be easily controlled.

  As shown in FIG. 9, test pieces (φ6 cm × 6 cm) in the X, Y, and Z directions were cut out from a mattress having a corrugated structure (“Pregler mattress” manufactured by Paramount Bed Co., Ltd.), and the following tests were performed.

Three long transparent PVC pipes (with an inner diameter of about 6 cm) are set up vertically, and the above-mentioned test pieces in a dry state are tightly fitted and clamped inside the lower end of the pipe, and a funnel is installed at the upper end. 1000 ml of water was poured at a constant speed. The distance from the lower end of the funnel to the upper end of the test piece was kept at 1 m.
Then, the time required for the water flowing down through each test piece to change from a thread shape to a drop shape was measured, and thereafter, this was repeated a predetermined number of times after a certain period of time. The test results are shown in Tables 1 and 2.

Further, the same test was performed by changing the distance from the lower end of the funnel to the upper end of the test piece to 15 cm. The test results are shown in Tables 3 and 4. In addition, when the amount of water contained in the test piece after completion | finish of a test was measured, they were respectively X: 40g, Y: 47g, Z: 43g, X: 32g, Y: 43g, Z: 44g.

As is clear from the above, the test piece in the X direction has higher water flow efficiency and excellent drainage than the Y and Z direction test pieces.
Since the mattress cleaning / disinfecting apparatus according to the present invention allows the cleaning water to flow down along the X direction, the filth and sterilized dead bodies (mold, mold, mites) adhering to and entering the mattress are sufficiently removed. It can be washed away. Moreover, since the mattress is disposed and held at a predetermined inclination angle, the entire surface of the mattress and the inside thereof can be efficiently washed away.

  The present invention is a mattress cleaning and disinfecting apparatus capable of sufficiently washing away dirt and sterilized dead bodies (mold, germs, ticks), etc. that have adhered to or invaded the mattress, and can prevent secondary infection, and mattress cleaning. It provides a method and has industrial applicability.
