TIIVISTELMÄ
Tämän tutkintotyön tavoitteena oli suunnitella Lojer Oy:n uudelle Leikkauspöydälle
Scandia OT340 huolto-ohjekirja. Tällä huolto-ohjekirjalla on tarkoitus tulla huoltamaan
Leikkauspöytää määräaikaishuolloissa, tarkistuksissa ja mahdollisissa vikatilanteissa.
Leikkauspöytä sisältää paljon elektroniikka ja hydrauliikkaa, joten tämän tyylinen
tekniikka vaatii paljon huoltotoimenpiteitä sairaala olosuhteissa. Leikkauspöytää täytyy
huoltaa määrävälein, jotta vältyttäisiin suuremmilta vahingoilta. Vahingot voivat olla
mittavia, jos laitetta ei huolleta oikein ja huolellisesti.
Tämä opinnäytetyö antaa huolelliset ohjeet pöydän määräaikaishuolloille ja
mahdollisten vikojen paikallistamiseen. Tähän opinnäytetyöhön on sisällytetty
huollettavuuden ja huolto-ohjelman suunnittelu. Huollettavuudessa perehdytään
mahdollisten vikojen paikallistamiseen, sekä niiden korjaamiseen. Huolto-ohjelma sen
sijaan pitää sisällään määräaikaishuoltojen ja tärkeiden tarkistusten ohjeistuksen.

table Scandia OT340. With this maintenance manual is purpose to make a regular
maintenances, check-ups and possible fixings for operating table.
Operating table Scandia OT 340 is high technological device, which includes technique
of electronics and hydraulics. In hospital circumstances this kind of technical device
needs lot of maintenance measures. Table need to be check out periodically to avoid
bigger damages. The damages can be large if table is not serviced correctly and
accurately.
The thesis gives accurate advices to the regular maintenance and possible trouble
situations for the operating table. For this thesis is included the plan of maintenance and
maintenance program. Maintenance includes troubleshooting and how to make the
fixations. In the other hand, maintenance program includes the helping for regular
maintenances and for important check-ups.
