Description

Luftpute for sykesenger. Air cushion for hospital beds.

Oppfinnelsen omhandler en luftpute spesielt beregnet til bruk i sykesenger til understøttelse av setepartiet og korsryggen på pasienter med et langvarig sykeleie. De vanlige luftputer som brukes til dette for-mål på sykehusene er ringformet, og de blir oppblåst til et tverrsnitt med form av en flattrykt oval. Til understøttelse av korsryggen og ryggens nedre parti blir det anbragt en vanlig firkantet dunpute, som legges tett inntil luftputens kant og som strekker seg et stykke oppover i ryggens lengderetning. Der hvor dunputen støter sammen med luftputens runde omkrets-linje oppstår det to hjørner hvor det er hulrom, og hvor korsryggen ikke får noen understøttelse av sidepartiene. Dette med-fører stort ubehag og smerter for pasienten etter en tids sykeleie. The invention relates to an air cushion specially intended for use in hospital beds to support the seat area and lower back of patients with a long-term hospital stay. The normal airbags used for this purpose in hospitals are ring-shaped, and they are inflated to a cross-section in the shape of a flattened oval. To support the lower back and the lower part of the back, a normal square down pillow is placed, which is placed close to the edge of the air cushion and which extends a little way up the length of the back. Where the down cushion collides with the air cushion's round perimeter line, two corners arise where there are cavities, and where the lower back does not get any support from the side parts. This causes great discomfort and pain for the patient after a period of illness.

For å unngå denne ulempe er luftputen ifølge oppfinnelsen gitt en annen form, idet dens ene halvdel er ringformet mens dens annen halvdel er utformet som halvdelen av en pute med firkantet omkrets og med det samme sentrale runde hull i luftputen. Denne pute anbringes under pasientens seteparti, slik at putens rette sidekant ligger på tvers av sengens lengderetning og nærmest korsryggen hvor den støter sammen med den vanlige firkantete dunpute, slik at det ikke oppstår noen tomrom hvor putene støter sammen. In order to avoid this disadvantage, the air cushion according to the invention is given a different shape, one half of which is ring-shaped while the other half is designed as half of a cushion with a square circumference and with the same central round hole in the air cushion. This pillow is placed under the patient's seat, so that the straight side edge of the pillow lies across the longitudinal direction of the bed and closest to the lower back where it collides with the normal square down pillow, so that no voids occur where the pillows collide.

Oppfinnelsen vil bli nærmere forklart i forbindelse med tegningen, hvor: Fig. 1 viser putene anbragt under en pasient i en sykeseng. Fig. 2 viser den kjente luftpute og en vanlig dunpute sett ovenfra. Fig. 3 og 4 viser luftputen ifølge opp- The invention will be explained in more detail in connection with the drawing, where: Fig. 1 shows the pillows placed under a patient in a hospital bed. Fig. 2 shows the known air cushion and a normal down cushion seen from above. Fig. 3 and 4 show the air cushion according to

finnelsen og en vanlig dunpute lagt inntil hverandre i sengen. the invention and a normal down pillow placed next to each other in the bed.

Fig. 6 viser et snitt etter linjen II—II Fig. 6 shows a section along the line II—II

i fig. 4. in fig. 4.

I fig. 1 angir 1 pasientens kropp i rygg-stilling hvor setepartiet understøttes av en ringformet luftpute 2 som støter inntil en fortrinnsvis firkantet dunpute 4, og som ligger på madrassen 3. Som det fremgår av fig. 2 dannes det ved disse vanlige ringformete luftputer et tomrom i hvert av hjørnene 5, hvilket medfører at korsryg-gens sidepartier ikke blir understøttet. Denne ulempe unngås ved den form som luftputen har fått ifølge oppfinnelsen og som fremgår av fig. 3 og 5, hvor luftputens 6 ene halvdel er -en del av en ringformet pute, mens luftputens annen halvdel er utformet som en halvdel av en firkantet pute, og hvor begge putehalvdeler har det samme sentrale gjennomgående hull og den samme tverrsnittsbredde b = b'. Luftputens rette side legges an mot den rette side av dunputen 4, og korsryggen får en jevn understøttelse over hele bredden. På grunn av at luftputens hjørne-partier 7 sam har et større tverrsnittsareal enn putens øvrige tverrsnitt ved b og b' vil disse skraverte partier blåses opp høyere enn resten av puten som vist i fig. 5. Herved oppnås den fordel at korsryggen ved sidepartiene får en full understøttelse, idet luftputens kontur, som det fremgår av fig, 6, danner en konkav linje som tilsvarer kroppens runding. In fig. 1 indicates 1 the patient's body in the supine position where the seat part is supported by a ring-shaped air cushion 2 which abuts a preferably square down cushion 4, and which lies on the mattress 3. As can be seen from fig. 2, with these ordinary ring-shaped air cushions, a void is formed in each of the corners 5, which means that the side parts of the lumbar spine are not supported. This disadvantage is avoided by the shape that the air cushion has acquired according to the invention and which appears in fig. 3 and 5, where one half of the airbag 6 is part of an annular cushion, while the other half of the airbag is designed as one half of a square cushion, and where both cushion halves have the same central through hole and the same cross-sectional width b = b' . The straight side of the air cushion is placed against the straight side of the down cushion 4, and the lower back receives uniform support across the entire width. Due to the fact that the corner parts 7 of the air bag together have a larger cross-sectional area than the other cross-sections of the bag at b and b', these shaded parts will be inflated higher than the rest of the bag as shown in fig. 5. This achieves the advantage that the lower back at the side parts gets full support, as the air cushion's contour, as can be seen from fig, 6, forms a concave line that corresponds to the rounding of the body.

Den luftpute 9 som er vist i fig. 4 har et større tverrsnittsareal ved b' enn ved b The air cushion 9 shown in fig. 4 has a larger cross-sectional area at b' than at b

hvorved de skraverte partier 8 av puten 9 whereby they shaded parts 8 of the pad 9

blir høyere enn ved puten 6, hvorved den becomes higher than at pad 6, whereby it

ønskete virkning blir enda bedre. the desired effect is even better.

Det ier mulig å utføre luftputen med It is possible to carry out the air cushion with

hel firkantet eller rektangulær omkrets, full square or rectangular circumference,

men det vil da bli forhøyete partier i alle but there will then be elevated parties in all of them

fire hjørner, og slike forhøyninger er ikke four corners, and such elevations are not

ønskelige på andre steder enn i korsryggen. desirable in places other than the lower back.
