Sub-bandage pressure measuring

Uvod: Elastične nogavice in kompresijske obveze so sredstva za zdravljenje številnih bolezenskih stanj. Za zagotovitev optimalnih pogojev zdravljenja je potrebno zagotoviti ustrezen tlak. Ustrezen tlak se lahko določi s pripomočki za merjenje tlaka pod obvezo. Obstajajo naprave za merjenje tlaka pod obvezo, ki delujejo na različne principe. Namen: Namen diplomskega dela je pregled podatkov o obstoječih napravah za merjenje tlaka pod obvezo in izdelava prototipa naprave za merjenje tlaka pod obvezo, primerne za uporabo v izobraževalne in praktične namene. Metode dela: Iz pregledane literature smo izbrali najbolj primeren princip delovanja prototipa naprave. Odločili smo se, da uporabimo primarni pnevmatski senzor in sekundarni senzor za tlak. Poiskali smo ostale kompatibilne sestavne dele in jih povezali v prototip naprave. Ugotavljali smo natančnost in ponovljivost meritev opravljenih s prototipom naprave. Rezultati: Prikazani so rezultati treh različnih sklopov meritev, s katerimi smo ugotavljali kateri je najboljši način merjenja tlaka z našo napravo. Ugotavljali smo pri katerih tlakih so opravljene meritve zanesljive in kakšen je optimalen volumen zraka, ki ga je potrebno vbrizgati v zračni mehur. Razprava in sklep: Rezultati so pokazali, da je naprava primerna za merjenje tlaka pri kompresijskem obvezovanju, ki zahteva višje tlake. Pri meritvah kjer delujejo nižji tlaki so rezultati nezanesljivi. Za univerzalno uporabo naprave, bi bilo potrebno nadaljnjo raziskovanje.Introduction: Elastic stockings and compression bandages are used for the treatment of different medical conditions. To ensure the optimum conditions of the treatment, it is necessary to ensure the appropriate pressure. Appropriate pressure can be determined by devices for measuring the pressure under bandages. There are devices for measuring the sub-bandage pressure that operate on different principles. Purpose: The purpose of the study was to collect data on existing devices for measuring sub-bandage pressure and to produce a prototype device for measuring sub-bandage pressure to be suitable for use in educational and practical purposes. Methods: From the reviewed literature, we chose the most suitable operating principle of the prototype device. We decided to use a primary pneumatic and secondary pressure sensor. We looked for other compatible components and connected them into a prototype device. We determined the accuracy and repeatability of measurements carried out with the prototype device. Results: The results of three different sets of measurements are shown by which we determined what is the best way of measuring the pressure with our device. We determined at which pressures the measurements are reliable and what is the optimum volume of air that needs to be injected into the air bubble. Discussion and conclusion: The results show that the device is suitable for measuring the pressure of compression bandages that require higher pressures. For measurements where operating pressures are lower the results are less reliable. For a universal use of the device, further exploration would be needed
