Description

Automatic extending mattress

Technical Field

One solution is to automatically extend hospital mattresses of standard length, i.e. therapeutic or inflatable mattresses, or other types of mattresses designed for beds with extendable load surfaces.

Background

Various types of mattresses are used in hospital beds, from standard mattresses to atypical mattresses such as therapeutic mattresses which are placed on the loaded surface of the bed. Air mattresses, including active and reaction mattresses, are a known type of therapeutic mattress. Active mattresses can be further divided into alternating mattresses and non-alternating, or constant, mattresses. Alternating mattresses are characterized by varying pressures in the various air chambers. These mattresses are primarily used to treat patients who already have bedsores. Non-alternating active mattresses are characterized in that they always have a low pressure.

The standard length of most active and reactive mattresses is 2 meters and a standard load surface length designed for hospital beds is also 2 meters.

Hospital bed manufacturers have long been producing beds with extendable load surfaces as the average height of the patient increases, so that hospitals do not have to keep an over-length bed for patients above average height. In most cases, standard beds with extendable load surfaces are equipped with mattresses having a standard length of 2 meters, which means that a trough (gap) occurs between the mattress and the bed head when the bed is extended. This gap must be filled and it is usually filled with an additional pillow or foam block, which the staff must insert into the space. This solution is accompanied by several problems. The first problem that arises is storage; the available storage space for these pillows becomes necessary. The area where pillows or blocks are stored is usually located outside the bed and therefore the staff must look for them. Such pillows or extension blocks are often lost. Another problem arises when the bed is used in its extended form. The mass often falls out of the gap or creates an uncomfortable gap between the mattress and the extension pillow, which can also lead to bed sores on the part of the patient's body that comes into contact with the gap. A third problem may arise when a patient who should use a therapeutic mattress of standard size falls into the extended section of the solid part of the mattress because of its higher than average height, which means that its therapeutic properties become useless and the patient is at risk of getting a bed sore where his body is in contact with the solid part of the extendable plate.

Of course, there are some mattresses that attempt to extend as the loading surface extends, so there is no need to place a pillow between the mattress and the head of the loading surface. Patent JP2006136669(a) is an example of such a solution. In this solution, the size of the mattress matches the length of the bed loading surface when the bed is extended, while the mattress is integral. However, the foot of the mattress is made of a soft material and is perforated, whereby the mattress length can be contracted when the bed is contracted. However, this is only applicable when the patient does not require any treatment, which may be disadvantageous in certain situations.

Another way of dealing with the gap between the mattress and the headboard is, for example, the technical treatment mattress solution of patent US5745937 (a), wherein the mattress is deflated by deflating the first and second air chambers. Some mattresses described in this embodiment extend or contract by a density ratio in the chamber. For this solution to work, a large number of inflatable chambers must be present in the mattress, which also requires a compressor to regulate the pressure in the chambers. In this solution, the mattress cannot be automatically extended simultaneously with the loading surface in case it cannot be adjusted by means of the compressor.

Disclosure of Invention

When extended hospital beds, nursing beds, examination beds, stretchers, etc. are equipped with a standard size mattress 2 meters long, the above-mentioned problems arise on the load surface of these beds. The proposed solution is for an automatically extending mattress, or more precisely a therapeutic mattress with a standard mattress length. Auto-extension is addressed using an extendable plate comprising at least one hollow foam chamber enclosed in a tight-fitting sleeve, with at least one outlet positioned on at least one lateral end. The extendable panel is also equipped with fasteners on at least one side of the outer cover, which can be used to attach the outer cover to the inside of the cover of a large outer mattress, or a standard length therapeutic mattress. A therapeutic or standard mattress (hereinafter referred to as a "mattress") has a sleeve that is larger than its standard length and width and therefore more precisely longer and wider, so that the mattress and extendable board will fit inside. A large casing (hereinafter referred to as "casing") is equipped with fasteners for attaching the extendable plate to at least one end on its inside. The extendable plate, when extended, is exactly as large as the gap between the mattress and the head of the bed loading surface.

The solution we propose is characterised in that the above-mentioned extendable plates are also incorporated into the larger casing of a therapeutic or other mattress. Because the head of the loading surface compresses the extendable plate placed in the casing of the mattress, the mattress and extendable plate on the loading surface of the extended bed will automatically fully retract when the bed returns to the original loading surface size. When this portion of the mattress is compressed by the headboard, air is released from the foam chamber through the vent, causing the mattress to collapse over the span required for bed extension. Conversely, the mattress loading surface will automatically extend as the bed loading surface extends, because the pressure exerted by the headboard on the extendable board will be released. At the same time, air will naturally flow into the one or more foam chambers through the vent. In this way, the extendable plate will straighten and expand, while the mattress will automatically extend, albeit mechanically.

The technical scheme is simple, economical and feasible. It will simplify the work of the staff handling the bed and reduce the hospital storage costs for additional plates or spare pillows. It increases the comfort of the patient, who does not have to wait for the bed to lengthen. Since there are no gaps on the friction surface where pressure sores may occur, the outer plates of the load surface do not fall off and the risk of pressure sores is reduced.

Detailed Description

Fig. 1 shows an automatically extending mattress when extended, which is designed for example for hospital beds, nursing beds, examination beds, stretchers or the like with an extendable usable load surface and in this case comprises the following configurations: a therapeutic mattress 2, an extendable panel 8 and a mattress cover 3. In this figure, a self-extending mattress 1 incorporates a therapeutic mattress 2 comprising a foam cover layer 4, the foam cover layer 4 being designed as a cover for the construction of air chambers 5 which are pneumatically connected by conduits and fitted into a moulded foam layer 7, with a second foam lining 6 between the air cells and the foam layer. The liner is designed to fill the gap between the air chamber 5 and the moulded foam layer 7 of the mattress 1, wherein the therapeutic mattress 2 of standard size (hereinafter referred to as mattress 2) is optionally replaced by a standard mattress of standard length.

The self-extending mattress 1 comprises a mattress 2 and an extendable panel 8, wherein both components are contained in the casing 3 of the mattress 1. The casing 3 of the self-extending mattress 1 is precisely large enough to accommodate the therapeutic or standard mattress 2 and the extendable plate 8 when extended. In a preferred embodiment, the mattress 2 may have one or more components made of one or more types of materials or chambers, such as air chambers, foam chambers, and the like. The casing 3 of the mattress 2 is exactly longer than a standard mattress 2 by the length over which the bed loading surface can extend. In the same way, the automatically extending plate 8 is precisely large enough to fill the gap between the mattress 2 and the head of the bed loading surface so that the patient's lower leg does not lie in the void space above the loading surface nor falls on the loading surface. In the preferred embodiment, the outer cover 3 of the mattress 2 is made of PVC, but may be made of any other material, such as fabric, upholstery or rubber coated fabric, or rubber or nylon, or other textile or upholstery fabric.

Fig. 2 depicts a side view of the mattress 1 automatically extended when assembled. In this example, the mattress comprises a therapeutic mattress 2 and an extendable panel 8. In a preferred embodiment, the self-extending mattress 1 may comprise a standard mattress 2 and an extendable panel 8. It is clear from this depiction that therapeutic mattress 2 ideally comprises several components, an underlying foam component and an air chamber 4 pneumatically connected by tubing. Furthermore, fig. 2 shows a section of the extendable plate 8 of the foot of the bed. Alternatively, the extendable plate 8 may be placed at the head of the outer casing 3 of the self-extending mattress 1. The figure also clearly shows that the extendable plate 8 comprises a plurality of parts, two hollow foam chambers 11, contained in the tight packing 9 and equipped with two vents 10 on each side. Alternatively, the extendable plate 8 may be provided with at least one vent 10 on at least one side of the sleeve. However, in a preferred embodiment, there may be more of these vents 10.

Fig. 3 depicts a front view of the independently extendable plates 8. It can be clearly seen that the foam chambers 11 are located in the tight-fitting pockets 9 and at the bottom end of the pockets 9 of the extendable panel 8 there are fasteners 12 which secure the extendable panel 8 to the inner wall of the larger outer shell 3 of the mattress 2. Fig. 4 depicts a bottom view of the extendable plate 8, from which it is clear that the foam chamber 11 is enclosed in the tight-fitting sleeve 9. In a preferred embodiment, the sleeve 9 is provided with three fasteners 12 on the outer bottom side of both lateral ends of the sleeve 9 to secure the extendable plate 8 to the inside of the larger outer shell 3 of the mattress 2. In summary, this shows a sleeve 9 equipped with six fasteners 12 in the preferred embodiment. Alternatively, at least one fastener 12 or a plurality of fasteners 12 may be positioned anywhere on the outside of the sleeve 9 of the extendable plate 8 so that the extendable plate 8 may be attached to the inside of the larger sleeve 2 of the mattress 1. The fastener 12 may be made of any component, such as a stud or button. Alternatively, the extendable plate 8 may be attached using other types of fasteners 12 from: velcro, zippers, buttons or studs, or buttons, clamps, staples, clips, or buckles. The outer casing 3 of the mattress 1 is also provided with fasteners for fixing the extendable plate 8. The fasteners of the extendable panel 8 fit directly into the counterparts of the fasteners 12, which are located inside the larger shell 3 of the mattress 2. By sealing the standard mattress 2 and attaching the extendable panel 8 to the larger casing 3, a self-presenting mattress 1 is formed. Alternatively, the extendable plate 8 may be fastened directly to the standard or therapeutic mattress 2 using fasteners 12. However, the mattress 2 must be equipped with a counterpart to the fastener 12, into which the fastener 12 of the extendable plate 8 will fit, so that the standard mattress 2 and the extendable plate 8 are integrated, resulting in a self-extending mattress 1. in another alternative, it may be a combination of the two methods of fastening the extendable plate 8 described above, so that the extendable plate 8 is equipped with fasteners 12 on different sides, so that it can be fixed to the mattress 2 and the inside of the casing 3, and then the casing 3 will form a covering for the entire self-extending mattress 1. The fastener 12 on the mattress 2 or inside the cover 3 forms a counterpart to the connector, which may be any of the following: velcro, zippers, buttons or studs, or buttons, staples or clips, clips or buckles.

In addition, fig. 5 shows a side view of the extendable plate 8, wherein the inner filling of the extendable plate 8 can be seen. This is ideally made of two hollow foam chambers 11 molded in the shape of two tunnels sealed in the tight-fitting sleeve 9, which are ideally equipped with two air vents 10 on the lateral sides. The figure also visually shows the fastener 12 which connects the extendable plate 8 with the interior of the outer cover 3 of the mattress 2. The vents 10 are located on the lateral sides of the extendable plate 8 and enable the foam chamber 11 to deflate itself and, conversely, to fill itself at atmospheric pressure without the use of a compressor. The tunnel-form foam chamber 11 desirably has an opening or cavity 13, or alternatively the chamber 11 and cavity 13 therein may be of any geometry. Alternatively, these openings or cavities 13 may take the form of holes, circles or semi-circles, rectangles, squares, triangles, and the like.

The basic principle of our proposed solution for automatic extension of any type of mattress is to put any model or type of mattress 2 into a large pocket 3 that is exactly as large as the bed loading surface when extended, regardless of the size of the mattress 2. The extendable plate 8 is fixed before the extension sleeve 3. The plate is configured to deflate itself and reduce its volume when a portion of the extended load surface contracts. If this is not the case, it must be removed from the sleeve and deflated in some manner. In contrast, the extendable plate 8 is configured such that when the bed load surface is extended, the plate 8 automatically fills with air and increases in length. There is no need to use a compressor to inflate the extendable plate 8. Automatic inflation is achieved using vents 10, which vents 10 form part of a sleeve of a hollow foam chamber 11. In the proposed solution, the vent 10 is ideally made of a plastic ring and mesh. However, the vents may also be made of other materials such as rubber or textiles, and may also have any geometric shape such as hole-shaped or circular, rectangular or square, triangular, etc. Ideally, the extendable plate 8 is detachable and the mattress for automatic extension can be removed. However, the extendable panel 8 of the mattress may alternatively be fixedly secured to the mattress 2 to form a unitary body. However, even in this case, the outer casing 3 of the mattress must be larger than the standard casing of the mattress 2 when not extended.
