Definitions
- the invention relates to the universal mattress with command module, designed for comfortable sitting, laying and leaning. It prevents the decubitus and cures it, ceasing the appearance of the new decubitus wounds in the same time.
- the invention and the name MUTI are devoted to my mother. She was a patient at a respectful clinic after the hip bone fracture, got the decubitus and ceased in infection. In this sad occasion I have realized that the hospitals and their medical stuff, even at clinical centres, are poorly equipped with the appliances to prevent and, even the less, to cure the bedsore.
- the measuring made by Khan, K. Lee and their associates indicates that the pressure at the supporting region is increased by 3 till 5 times if any of the prominent bones occurs within the region.
- Using well designed mattresses it is possible to reduce such a high pressures, according to my investigations, to the allowed pressure in the venal capillaries (fig. 2.5 and 2.6).
- the pressure under 1.6 kPa can be obtained only if the body is completely free of upholding.
- the mattresses are not artificially ventilated, heated, and their fluid capacity (for urine or water) is poor.
- the mattress can be used as a bedstead on the floor, in the tent, in all catastrophic circumstances.
- the mattress and the pillow are independent functional entities, intended to be used as a protection against decubitus and its healing. They can be used for comfortable sitting, laying and leaning. Mattrasses and pillows can be incorporated in beds, chairs, wheelchairs (fig. 16.4), vehicle seats, used to lean the head, as an aid bedstead (fig. 15.3), straightly on the floor or ground (fig. 15.1 and 15.2).
- MUTI This is the general trademark for a whole range of mattresses and pillows based on the invention. Particular trademarks are: command unit - CO
- MUTI for decubitus prevention P-MUTI for decubitus therap> - T-MUT1 for prophylaxis and therapy - PT-MUT1 head cushion - H-Ml'TI armchair pillow - AC-MUTI wheelchair pillow - IC-MUTI car seat cushion - C-MUT1
- Optimal operating pressure - P-MUTI for decubitus therap> - T-MUT1 for prophylaxis and therapy - PT-MUT1 head cushion - H-Ml'TI armchair pillow - AC-MUTI wheelchair pillow - IC-MUTI car seat cushion - C-MUT1
- MUTICO operates at the optimal pressure, taking into the account the weight, body position and patient's antropological measures.
- MUTI is made as two rows of strictly dimensioned chambers (fig 1.4 and 1.6).
- the material is very flexible, sometimes combined with sponge rubber layer (fig. 2.2).
- Such a solution gains the larger contact area with the mattress. This results with a pressure that is as close as possible to the allowed one - an optimal pressure for the given conditions.
- Operating pressures are proofing that MUTICO, according to the invention, is satisfactory solution.
- the values of the operating pressures are: less than 6 kPa when a patient sits; less than 4.2 kPa when laying on a single row of chambers and less than 3.33 kPa if both rows of chambers are used (fig. 2.5). This means: if only the arterial capillaries pressure is meritorious for the efficient blood circulation, mattress solution would, according to the invention, satisfy the requsts, yet using a single row of chambers to uphold the body.
- MUTICO enables to change the supporting region from one row of chambers to t o rows and vice versa, from any single row to the both rows.
- the change can be easily done by CO automatically or semiautomatically, or even manually, by the patient himself or somebody of his family. We should keep in mind that it means the substitution of two medical caretakers.
- MUTICO enables the timing of supporting region change, ranging from a few minutes to one hour or more. Hence, it is possible to change the supporting region more frequently when the pressures are higher, or vice versa, if the pressures are lower, to slow down the exchange.
- the rate of discharge for a certain row of chambers can be altered from a few seconds to a few minutes. According to the rate of discharge of the chambers, the changes of contact area may be unperceptible, or even stroking changes comparable to a very slow engine action. Although the stroking alteration is more likely the healthy person movements, the invention enables the choice proper to a patient.
- the same MUTI mattress, used for decubitus prevention, can be with some additional equipment (fig. 18) simultaneously used to cure the bedsore (fig. 17).
- patient uses the complete convenience of MUTICO for decubitus prevention; only difference is the absence of vertical force in vicinity (radiuses 10. 12. 15. 20 cm) of the decubitus ulcer.
- MUTI is designed to accept the fluid (urine, burns liquid, washing water) not keeping it on the surface, to avoid the skin irritation 8.2 Collected fluid can be discharged into the appropriate tank (additional equipment, fig. 19).
- Esthetically designed seat furnish (fig 16.2) can be obtained combining mattresses and pillows consisting of chambers w ith a layer of sponge rubbei Seat with lest (fig
- MUTI made of single chambeis row with the sponge (fig 14 3), MUTI-PP and MUTI-PD (fig 14 4) with or without sponge, can be used as a single functional entity to uphold the head If the support with changeable elevation is added below the cushion (fig 14 1 and 14 2), it can be used, m the same time, to change the inclination of the head 12.
- Command unit
- the command unit enables changing of contact regions, simultaneously keeping, selfadjusting and reproducing the optimal pressure.
- the air may not leave a row of chambers before the optimal pressure is obtained in one or both rows of chambers.
- Operating characteristics 1 - 12 result in: solution to supporting area exchange, frequency of changes, chamber discharge rate and optimal pressure in chambers. At will, those operating characteristics enable the movement simulation (for immovable patients). Such benefits may be pleasant and utile even to the healthy persons. As there are the other advantages, like easy washing and drying, ventilation, heating etc., all the requests for successful decubitus prevention and cure are fulfilled, and it is the basic objective of the invention.
- MUTI operates at optimal pressure, avoiding unnecessary and uncontrolled high pressures at upholding zones.
- the optimal mattress height is the one making possible a high rate of contact area use, without the loss in comfort or upholding stability.
- 80 mm is taken as the optimal mattress height for it's general use.
- Lower mattress (less than 50 mm) has to have higher pressures within the chambers, particularly for sitting, to avoid the contact of exposed parts of the body to the hard base (compare fig. 1.1 and 1.3).
- Mattresses higher than 100 mm incline to be unstable and uncomfortable, and the increase of contact area is not significant.
- the optimal mattress height can be realized combining single row of chambers, R in diameter, with a sponge rubber layer of a certain height.
- the first distribution of body weight producing the pressure.
- Another (re)distribution of pressures is indirect, transiting from the sponge layer to the row of chambers (fig. 2.2).
- the pressure is distributed over the whole contact area, being higher above the inflated chambers, varying and lower above the deflated ones, depending upon the chamber diameter, the pressure in inflated chambers, sponge thickness, etc.
- the optimal pressure being the basic characteristic of the invention, is achieved, kept, reproduced and selfregulated through the solutions of chambers, choice of materials, and MUTI&CO design.
- the outcome of the changes are variable heights along the mattress as it is loaded.
- the same symbols are used to illustrate relative positions and a number of chambers when both series of chambers are inflated (fig. 10.2).
- the central area is filled with parallel and diagonally positioned chambers PD, and the edges of the pillow are two fields filled with PP and PDP chambers (instead of PP and PDP chambers it is possible to fill MUTI edges with PD chambers or a sponge rubber layer).
- the cloth between the chamber rows can be tightened arbitrary. If it is looser, the upper row chambers can drop deeper between the lower row chambers; in this manner the mattress height can be lowered from 2R to R, particularih in its middle. Tightening the cloth the cloth can raise from R to 2R.
- Changing the height of a mattress w ith PD distributed chambers can be done using a cloth of a certain width that is moved betw een the chambers along the pillow (fig. 12). For instance, moving the cloth from the position I to II. respectively to III, the area of PD chambers if enlarged versus the P and D chambers area.
- the disks fixing elements (fig. 18.3 and 18.4) provide a gap between the disks necessary for undisturbed air flow.
- the disks can be positioned anywhere on the mattress, making the openings in the rubber cloth.
- One disk is positioned under the rubber cloth, the another above the mattress chambers, both tightened by the fixing elements.
- MUTI-PD is optimal for decubitus therapy, and the most appropriate area is the middle of the mattress.
- MUTI can hold a certain amount of the liquid (fig. 19).
- MUTI itself is a repository if front sides with chamber collectors are closed, while the bottom and the lateral sides are rubber cloth.
- the central part of the MUTI bottom (fig. 19.3) is equipped with an porous tampon (fig. 19.1) which drenches and capillary drains the liquid to an urine bag (fig. 19.4), MUTI in the case necessity can be used as an container for liquid.
- the urine or washing liquid can be drained through the collector openings as well (fig. 19.2).
- the pillow enables spontaneous flow of the air:
- a certain quantity of the air goes out.
- the quantity can be directed between the MUTI chambers, and further to the certain support region (fig. 20 and 21 , air flow 3).
- the air can be conducted directly from the air source into the certain MUTI gap (fig. 20 and 21, air flow 2) to ventilate MUTI.
- the hot air can be blown into the chambers (fig. 20, air flow 1 ), and left out into MUTI gaps (air flow 3).
- air flow 3 air flow 3
- the hot air can be redirected by the valve (fig. 21.2) and directly injected between the chambers (fig. 20.1 , air flow 2), so heating the MUTI space at a convenience.
- MUTI is designed according to the directives revealed from the operating characteristics description.
- MUTI consists of the chambers made from a rubber tube of certain diameter. Rubber was chosen to make the mattress because of the following characteristics:
- the chambers can be stacked:
- MUTI-PD is made of:
- MUTI is used as a autonomous entity, its air valves are located at one end, and if more MUTIes are use for a single bedstead, two more valves are added to the another end of the collector (fig. 4.2).
- the valves are designec to open when the air couple is inserted into the valve hole (fig. 4.5). When the couple is pulled out (fig. 4.7), the valve closes air flow (fig. 4.6).
- Such a vah e enables MUTI to be used for changing the support place or as an autonomous sitting unit. Additional safety plugs are intended to the mattress MUTI used just for leaning (fig. 4.4). Chamber ends of a mattress are inserted into the chamber collector (fig. 3.2). The chamber collectors are enabling:
- the collector chamber width denoted MUTI (S). depends on the number of chambers (n) and chamber diameter (R):
- Usual mattress lengths are: • bedstead up to 2000 mm, • seat up to 500 mm,
- the chambers are affixed (in the inflated state) to the rubber cloth (fig. 5.1). In this way MUTI bottom is protected against the mechanical damages, a desired distribution is obtained and the chambers are fixed, defining operation area of certain chambers.
- Convenient material is a stretchable one, enabling the enlargement of contact area and good ventilation through the pores within the cloth.
- MUTI can be inserted into the cushion cover as well.
- MUTI-R consists of a series of chambers (n) placed in a single row with diameter R (fig. 5). Based on the single row mattresses (fig. 13.1) the following typical cushions are developed:
- MUTI can have integral covering for both seat and rest.
- the pillow can be inserted into the separate pillowslip and tied to the seat by the band.
- MUTI-PP chambers are made of rubber tubes (diameter R. length L) vulcanized to form a closed ring, like a bicycle tire: than it is stretched (fig. 3.4) to obtain a single chamber of the two tubes positioned one above the another.
- Alternating chambers of MUTI-PP are connected by an appropriate air splitter (fig. 3.1 ).
- a rubber cloth is used for the bottom of the pillow. Between the rows of chambers a strong cloth can be inserted or the chambers belonging to one row are glued to the appropriate chambei s in the another row.
- the longer triangle side (a) equals in length to the parallel placed chamber
- the shorter triangle side (b) equals the chamber diameter R and meets the step of winding the tube
- the length of hypotenuse (c) equals the diagonal
- c 2 a 2 + R ⁇ .
- this chambers arrangement is called parallel/diagonal (PD).
- Making a MUTI-PD starts with winding of two rubber tubes, or a single rubber tube, from one MUTI corner to the opposite MUTI corner according to a certain arrangement and with a leap equal 2R or R, around two axes spaced mutually for a pillow length.
- On the lateral sides of the pillow for technological and functional reasons, along the diagonal positioned chambers, there are two parallel fixed chambers or a sponge layer of an appropriate diameter. This gives more height to the lateral mattress ends, preventing a patient to fall from the bed.
- Some of the standard chamber collectors are affixed to the frontal sides of the mattress.
- the air valve is installed at one end of the rubber tube, or on both ends if needed.
- the bottom of the mattress is provided with a rubber fabric.
- the cloth between the rows of chambers can be installed in a different ways:
- a few kinds of command units are designed for MUTI:
- 1.1. manual CO consisting of a pump driven by a hand (fig. 22.6) or by a leg (fig. 22.5). a backflow valve and a pressure reducing valve (fig. 22.4).
- 1.2. partly manual CO. consisting of an electromagnetic (membrane) pump (fig. 22.7), backflow valve (22.1 1), a pressure reducing valve (fig. 22.4) and a manual control device (fig. 22.9).
- PCO consists of:
- the compressed air source for semiautomatic and automatic command unit operation and inflation of MUTI can be:
- Miniature compressor plant consists of:
- a backflow valve (fig. 23.2) installed behind the pump, to prevent the release of the air from the system: this avoids decreasing the pressure of the chambers and therefore frequent switching the pump on and off.
- the backflow valve has to operate reliably at the low pressures typical for the system (20 kPa or less).
- a reservoir (fig. 23.3 • of a certain capacity to secure, together with the backflow vah e. a smooth and reliabK system operation.
- a micro switch ( fig. 23.4) to operate the pump automatically.
- the micro switch operates properly using a big difference in pressures within the reservoir and MUTI: in this way the system maintains reliably inflated to the desired pressure before the pump disengages itself.
- the micro switch has a knob to adjust the operating pressure within the reservoir.
- the air compressor plant designed according to the invention is autonomous, and once switched on continues the operation automatically.
- Miniature compressor plant is a complete product according to the invention.
- the compressor plant has to be placed into the separate, acoustically isolated room.
- the pneumatic equipment has the reduction valve and air outlet by each bed. To use MUTI, it is enough to plug its control unit into the air outlet.
- a reduction valve (fig. 23.5) that provides reliable reaching and reproducing of the desired pressure within MUTI.
- the pressure can be red at the reduction valve scale.
- a manometer (fig. 23.6) for observing the pressure within the chambers and the changes in them. It is a sensitive instrument, rather expensive, but as a replacement for eventual pressure controls, an ordinary blood-pressure meter can be used, or the pressure is red from the reduction valve.
- a control unit (fig. 23.7 and 22.9) which is a manually operated valve 5/2 adapted for use with MUTI. There are three operating positions: zero (middle) position - the both series of chambers are inflated, and two extreme positions - a single series of chambers is inflated (A or B).
- a throttle valve (fig. 23.8) to adjust the rate of deflating. If in the throttle valve hole, where the air exhausts, a small pipe is inserted and immersed into the glass of water, than it is possible to observe the speed of the air exhausting the chambers.
- the hole can be used to connect a blood-pressure meter to control the pressure within the chambers.
- the automatic command unit consists of:
- the air source, manometer, reduction valve and throttle are identical to those used in semiautomatic device.
- the switches and manometer operate based on changes of pressure in the reservoir and a particular series of chambers.
- the time relays are used to set the time intervals when inflation and/or deflation of particular series of chambers are to occur.
- any of the referred command units and compressed air sources can be used to accomplish any task.
- the operations like supporting area interchange or pressurizing are accomplished using a manual device or the mini pump and a blood-pressure meter.
- a manual device or the mini pump and a blood-pressure meter To inflate MUTI w ith manual CO the air couple is inserted into the valve hole of series of chambers to inflate (A or B. or A+B, fig. 22.10). After the desired pressure is reached, the couple is pulled out (fig. 4.7) and replaced with a safety plug (fig. 4.4). If a series of chambers is to be deflated, the couple (disconnected from the pump) is inserted into the appropriate valve hole. If a partly manual device is used, there is no need to insert and pull out the couples from valves when a change in the chambers takes place.
- the chambers are inflated to the pressure as adjusted on pressure regulator, or till the user himself feels the pressure that suns him at most, or till he is separated from the hard bedrock.
- the pump and pressure regulator are taken of MUTI and valve hole is closed with a safety plug. The pressure regulator is sufficient to reach and reproduce the desired pressure at any time.
