Definitions
- the present invention aims at providing a mattress having a built-in alarm function, which may be used in the same way as conventional bed mattresses. Therefore, a primary object of the invention is to provide a mattress that without outer installations is able to reliably detect whether a person lies on the same or not. An additional object is to provide a mattress that not only is simple and inexpensive to manufacture, but also enables good lying comfort. Yet an object of the invention is to provide a mattress that to the largest feasible extent guarantees that an alarm is released as soon as a patient leaves a lying posture, i.e. already when the same rises to a sitting posture, in which the bed has not yet been abandoned. According to the invention, at least the primary object is attained by the features defined in claim 1. Preferred embodiments of the invention are furthermore defined in the dependent claims .
- the invention is based on the intention to mount a pressure sensing device and an interrupter member, preferably electrically coupled to an alarm device, inside at least one hollow space formed in the mattress.
- the sensing device detects a distinct pressure against the top side of the mattress
- the interrupter member is effected in such a way that the alarm device is kept inactive, but as soon as the pressure against the top side of the mattress ceases, the alarm device is activated.
- a plurality of hollow spaces with appurtenant pressure sensing devices and interrupter members are arranged within a limited, substantially central area of the mattress.
- Fig 1 is an exploded view in perspective showing different parts included in the mattress according to the invention
- Fig 2 is a schematic planar view from above showing the location of a number of hollow spaces in the mattress
- Fig 3 is an enlarged, partial longitudinal section through the mattress.
- the mattress is in its entirety designated 1.
- the mattress has a rectangular or parallelepipedic basic shape, by being delimited by two parallel long side surfaces 2, 3, two short end surfaces 4, 5, which are likewise mutually parallel, as well as plane top and bottom sides 6, 7.
- the mattress is composed of three flat or sheet-shaped cushions, viz . upper and lower cushions 8, 9, as well as an intermediate cushion 10.
- the intermediate cushion 10 a plurality of, more precisely three, mutually spaced-apart, through-going openings 11 are recessed, which form hollow spaces inside the mattress when the different' cushions are united with each other.
- all cushions may be made of conventional foam rubber or the like and united with each other by agglutination.
- the dimensions of the mattress and the different cushions may vary, per se.
- the upper and lower cushions 8, 9 separately has a thickness of 5 cm, while the intermediate cushion 10 is thinner and may have a thickness of 2 cm.
- the total thickness of the mattress may amount to 12 cm.
- the length L of the mattress suitably amounts to 200 cm, while the width B may be either 80 cm or 90 cm.
- the dimensions of the openings or hollow spaces 11 may vary. In the example, the width Bl amounts to 56 cm, while the axial extension or the length LI amounts to 17 cm.
- Solid material edge por- tions 12 are thus left, the width of which amounts to 12 cm if the width B of the mattress is 80 cm (17 cm when B is 90 cm) .
- Partition walls 13 between individual hollow spaces 11 may advantageously have a width or thickness T of 7 cm.
- the part of the mattress that is adjacent the short end 4. constitutes a head end portion 14 against which the head of the lying person may rest.
- the axial extension or the length L2 of this head end portion 14 may in practice amount to 75 cm.
- the corresponding length of a foot end portion 15 then amounts to 60 cm.
- a pressure sensing device is mounted, in its entirety designated 16, which interacts with an interrupter member 17, which in turn is coupled to a schematically shown alarm device 18.
- the interrupter ⁇ member 17 may advantageously consist .of a switch, which is con- nected to the alarm device electrically, more precisely via a cable 19.
- the alarm device 18 is shown in the immediate vicinity of the bottom side of the mattress.
- the cable 19 may in practice be drawn inside the mattress to a short end, where it ends in a female contact in which a male contact on an additional cable from the alarm device is insertable.
- the pressure sensing device 16 consists of two plates 20, 21, the lower 20 one of which abuts against the bottom of the hollow space. At one of the edges thereof, shown to the left in fig 3, the plates are inter-connected via a hinge 22.
- This hinge may for instance consist of welded together or casted integrally portions of the plates, which may be made of stiff, although deflectable plastic.
- the two plates are spring-actuated in order to always aim at springing out from each other towards the position shown in fig 3, in which a gap 23 between the free edges of the plates has a maximum width.
- This spring action may either be provided by means of specific, spring instruments not shown, or by the plastic sheets being casted or shaped with a certain prestress that guarantees that the gap 23 obtains the desired width in the unloaded state of the sensing device.
- the pressure sensing device is shown in an unloaded state, in that no person lies on the mattress.
- the switch 17 closes the electric circuit so that the alarm in question, e.g. a sound signal, is released.
- the plates 20, 21 are pressed together in the area of the gap 23, whereby the switch is effected so that the electric circuit is opened or broken, whereby the alarm ceases.
- the proper alarm device may be equipped with a particular off button 24 by means of which the alarm may be switched off in a conscious and controlled way by certificated personnel, more precisely in connection with the patient leav- ing the bed in an authorized way.
- the pressure sensing device 16 is placed in such a way that the hinges 22 are facing the head end of the mattress. This means that the real pressure sensing takes place in the area of the rear part of the hollow space.
- pressure sensing in the hollow space positioned closest to the head end 4 takes place at a relatively large distance from the head end 4, viz. approx. 90 cm from the head end.
- the different pressure sensing devices and appurtenant switches supervise the backside and legs of the lying person, rather than the shoulder portion/head. Therefore, if the lying person sits up in the bed - something which usually takes place in the area closest to the pillow - the alarm is released even before the patient has had time to leave the bed. In this way, nursing staff is at a very early stage given the possibility to prevent that the patient uncontrollably moves far from the bed.
- said plates have approximately the same shape and size as the appurtenant hollow space. In this way, the plates cannot move in the hollow spaces .
- the invention is not limited only to the embodiment described above and shown in the drawing.
- the exemplified dimensions may also be varied in several ways within the scope of the subsequent claims.
- the pressure sensing device may, for instance, effect the alarm device in a radio technical way.
