Description

INFLATABLE MATTRESS SYSTEM WITH VIBRATION

Field of the Invention

The present invention relates to hospital equipment and especially to a mattress system for hospital room beds or the like,

Background of the invention

When patients remain in bed for a long time it is possible to develop ulcers or bedsores, due to the pressure exerted on the skin and subcutaneous tissues due to the skeletal prominences of the skeleton and the object on which the patient rests, such as a mattress. This pressure produces tissue anoxia or ischemia. Cutaneous tissues break progressively leading to the destruction of the underlying soft tissue. If the ulcer appears it is very painful and very slow healing. Bacterial infections are difficult to avoid and often prolong the healing process.

Likewise, the person in bed without the ability to move on their own suffers from various complications in their health, one of them being the generation of phlegm in the respiratory tract, which due to their physical state cannot expel them individually, therefore, It requires the help of doctors, nurses and / or specialized instruments.

The state of the art in US4425676 describes a cushion to reduce the incidence of ulcers in immobilized patients, comprising: (a) an enclosure formed by an upper sheet of flexible air-permeable material and a lower sheet of impermeable material in air, said lower sheet is connected at its periphery to the periphery of said upper sheet; (b) an amount of loose filler material contained within said enclosure; (c) means for directing an air flow in said enclosure; and (d) a deflection system within said enclosure in the form of a series of strips of material that is connected between said upper and lower sheets of said enclosure and disposed transversely to the direction of air flow and in order to limit the migration of said filler material away from high pressure areas caused by the distribution of shape and weight of a lying patient on said upper sheet of said enclosure.

The disadvantages of the other known mattresses with respect to the invention are:

They do not have a vibration system: By not having a vibration system, other anti-decubitus mattresses do not help the expulsion of secretions from the respiratory system, nor do they stimulate the bones and muscles of patients, so they do not help in the prevention of symptoms caused by pneumonia, or help prevent muscle atrophy.

Uniform groups that do not adapt to the shape of the body: Because the groups of other products have inflatable sections of a uniform size, they do not adapt to the shape of the body. On the contrary, the mattress of the present invention has inflatable sections of different sizes for the lower back and legs, which makes it ergonomic.

Lower stability: Other mattresses, having no supports tend to bend easily when placed on a bed, while the mattress of the present invention, thanks to its foam rubber supports maintains the shape on soft surfaces.

Uncomfortable pillow area: commercial mattresses do not have an area to place a pillow of your choice, resulting in the patient's head having constant movement due to the action of inflation and deflation.

The present invention is designed to prevent the appearance of bedsores in prostrate patients and in people who for various conditions need to spend a lot of time in bed or in the same position, inflation and Deflated its two groups of cylinders has the ability to alternately release the pressure exerted by the mattress on different sections of the body, thus allowing the amount of blood to reach the skin is sufficient, thus helping to prevent the appearance of bedsores on the patient's skin.

Also, the present invention is designed to help prevent the symptoms caused by pneumonia by a vibration module in the support located at the level of the lower respiratory tract. This vibration module is responsible for helping the patient to expel secretions, thus reducing the accumulation of these in his respiratory system. In addition, it has a vibration module in the support located at the level of the buttocks and a vibration module more located in the support at the level of the calf and ankle, which are designed to stimulate the bones and prevent muscular atrophy. What makes it different from other antiescaras mattresses, since these do not have these modules.

The mattress of the invention is an inflatable mattress designed to help prevent the appearance of bedsores in prostrate patients, has groups of inflation and deflation cylinders constructed of different sizes which makes it ergonomic for people who use it.

In addition, the alternation of inflation and deflation of these groups of cylinders relieve pressure points in the body thus allowing blood to circulate through the body in sufficient quantity. Another feature that helps improve the quality of life of people who use it are its vibration modules, which help in the prevention of symptoms caused by pneumonia, as it facilitates the expulsion of secretions from the respiratory system of those who use it and help prevent muscle atrophy by stimulating the muscles.

The mattress of the invention is made of modest grade plasticized PVC, which is hypoallergenic to help people reduce symptoms. or allergic reactions, non-toxic so that you can be in contact with the patient without any problem, self extinguishing in case of an accident and rolling to avoid air leaks and obtain excellent mechanical resistance.

The design of the mattress of the invention was carried out in such a way that it adapts to the bodies of people of different ages, heights and weights, making it a device that targets different types of users.

Its design allows it to work with inflation and deflation groups and different sizes of cylinders.

The present invention provides an inflatable mattress system with vibration comprising: a mattress with an upper portion and a lower portion, a group of supports located below the lower portion of the mattress; a vibrator located in each of the supports, the vibrators are electrically connected to a controller; The mattress includes groups of cylinders with a first size and a second size located alternately along the mattress.

To give a better understanding of this utility model, a description of it is provided below, along with the accompanying drawings and in which:

Figure 1 shows an exploded view of the mattress of the invention;

Figure 2 shows the parts of the vibrator used in the present invention;

Figure 3 shows the block diagram of the electrical and control stages of the present invention; Y

Figure 4 shows the block diagram of connections between the different components of the present invention. Detailed description of the invention

With reference to figure 1, the inflaWe 10 mattress is formed by two layers of plasticized PVC 20 and joined by a weld 30 which forms two air chambers divided by groups of cylinders across the width of the mattress. The air chambers are each connected by a 40.41 side duct with special shape to reduce the folds and obstructions of the air flow that can be caused by shrinking the mattress. It is defined as a duct in a special way because it is formed by curved cylinders so that at the moment in which the mattress is contracted by inflation, these ducts can absorb the contracted distance without suffering a considerable change so that the duct is clogged, with this allows the ducts to always be free for air flow even when the mattress is in contraction and expansion movement. The cameras in turn are independently connected to two connectors 50, 51 to introduce air into the cameras.

The mattress contains two different sizes of 60 cylinders, located in groups achieving an ergonomic model. In which the patient's back is located in the group of small cylinders of the upper part 70, the lower back is located in the group of larger upper cylinders 80, the buttocks in the intermediate cylinder groups of smaller size 90, the backs of the knees on the groups of lower cylinders of larger size 100 and ios feet on the lower cylinders of smaller size 110.

The mattress supports 120, 130, 140 are located at the bottom of each of the smaller groups of cylinders to compensate for the height and stiffen the mattress structure.

The primary support 120 is composed of two cushions 150, 160 joined by a weld 170, the upper cushion 150 contains the area for the installation that the patient requires. The lower cushion 160 houses an electric vibrator 180 and is located in the high back of the patient, in addition it contains a cable 190 which is connected to the control cabinet 200 to supply the current to work. The secondary supports 130, 140 are located below the groups of cylinders of smaller intermediate and lower diameter 90 and 110, each containing an electric vibrator 181 and 182 and a cable 191 and 192 which is connected to the control cabinet 200.

In figure 2, the vibrator 180 is shown which is located in the lower cushion of the primary support 160 directly transmitting the vibration towards the patient's high back and the vibrators 181 and 182 located in the secondary supports 130 and 140 which are located below the groups of cylinders of smaller intermediate and lower diameter 90 and 110. Each vibrator 180, 181 and 182 has an electric motor 210 making an unbalanced mass 220 rotate and generate the vibration. The housing of each vibrator 230 is formed by a tube that prevents contact of the motor with any external agent. To close the faces of the tube, two covers 240, 250 are installed, one of them with a hole 240 where the power cable 190, 191 or 192 is inserted for each motor 210.

The principle of operation of the vibrators consists of an unbalanced mass that rotates at a certain number of revolutions which causes a vibratory movement, which is transmitted to the back of the prostrate patient. The motor 210 of the vibrators 180, 181 and 182 receive the voltage and current controlled from the cabinet for proper operation.

The control cabinet 200 is responsible for managing the air flow to the mattress chambers 10 by means of two pneumatic outlets (not shown) to which the pneumatic hoses 270 are connected and controlling the electric vibrators, which are connected by current output to the cable 190, 191 and 192 of the vibrators. They are formed by two housings 290, 300 which allow that no external agent can be introduced inside. Said cabinet 200 has a connection 280 to an electrical outlet.

For the control an electronic controller is used (not illustrated), this processes the options selected by the user through a graphic interface, which consists of a touch screen 310. The control of the vibrator is carried out when controlling the speed of a comment motor Direct that has an unbalanced mass, this is connected to a transistor that is responsible for receiving the PWM signals from the controller to generate the voltage that will reach the motor thus controlling its speed with which the vibration intensity of the mattress varies.

The socket 280 is connected to a 127 VAC power supply, which can be cut by means of a 2-position electrical switch; This voltage directly feeds a generic compressor for inflatable mattresses and a rectifier circuit to power the controller and electric motor respectively.

For the installation and commissioning of the device the inflatable mattress 10 is located in the area where the user will be located, once the inflatable mattress 10 is in the desired place, one end of the hoses 270 is connected to the control cabinet 200 and the other end to connectors 50 and 51 of the inflatable mattress. Then, the control cabinet 200 is connected to the power supply, the inflation and deflation system starts when the ignition switch is activated (not identified). Once the inflatable mattress is full of air, the support 120 is placed under the cylinders of smaller diameter 70 and the supports 130 and 140 under the cylinders of smaller diameter 90 and 110. For the control of vibrators 180, 181 and 182 the control cabinet has a touch screen 310 from which it is possible to customize times, intervals, intensity, duration and ignition. In addition, from the touch screen 310 it is possible to modify the pressure of the inflatable mattress 10.

The present invention has been described and illustrated in its preferred embodiment, however, a person skilled in the art will be able to visualize variations that fall within the scope of the following claims.
