Description
Przedmiotem wynalazku jest aparat do pomiaru temperatury polimeryzacji zwlaszcza mas akrylo¬ wych jako implantatów, zlozony z zaizolowanej ko¬ mory, naczynia do umieszczenia masy akrylowej oraz miernika temperatury.The invention relates to a measuring apparatus polymerization temperatures, especially of the acrylic masses as implants, consisting of an insulated horse moire, vessels for placing acrylic mass and a temperature gauge.
W znanych aparatach do pomiaru temperatury polimeryzacji stosuje sie zaizolowana komore w której jest umieszczony termistor lub termopara zatopiona w plytce aluminiowej, w gipsie lub za¬ nurzona w piasku. Koncówka czujnika termistora lub termopary wystaje kilka milimetrów ponad powierzchnie materialu w którym jest zatopiona i jest usytuowana w poblizu naczynia ze skladni¬ kami masy podlegajacymi procesowi polimeryzacji.In known temperature measuring apparatus an insulated chamber is used for polymerization which has a thermistor or thermocouple embedded in an aluminum plate, in plaster or on a wall immersed in the sand. Thermistor sensor tip or the thermocouple protrudes a few millimeters above surfaces of the material in which it is embedded and is situated near the syntax vessel mass undergoing the polymerization process.
Stwierdzono, ze odczytane wyniki pomiarów tem¬ peratury w czasie polimeryzacji dla tych samych materialów wykazuja znaczne rozbieznosci w od¬ niesieniu do wysokosci piku temperatury jak rów¬ niez jej przebiegu. Znaczna bezwladnosc w odczy¬ tach wynika z niewlasciwego doboru komory i roz¬ mieszczenia elementów miernika temperatury.It was found that the read results of the temperature measurements were peratures during polymerization for the same materials show significant discrepancies in the height of the temperature peak as well not its course. Considerable inertia in reading tach results from improper selection of the chamber and expansion housing the elements of the temperature gauge.
Celem wynalazku jest opracowanie aparatu za¬ pewniajacego maksymalna dokladnosc pomiaru temperatury oraz mozliwosc stosowania przy bada¬ niach róznych grup mas akrylowych.The object of the invention is to develop an apparatus for for maximum measurement accuracy temperature and the possibility of use in tests different groups of acrylic masses.
Aparat do pomiaru temperatury polimeryzacji wedlug wynalazku zostal zbudowany przy zreali¬ zowaniu zalozen zakladajacych pomiar temperatury w warunkach najbardziej zblizonych do wystepuja¬ cych w bezposrednim stosowaniu badanego mate¬ rialu. Komora termoizolacyjna zostala wyposazona 2 w grzejnik oraz czujnik temperatury polaczony z termoregulatorem dla uzyskania temperatury wyjsciowej okreslonej warunkami stosowania masy akrylowej. Czujnik miernika temperatury polime¬ ryzacji jest wprowadzany do badanego tworzywa.Apparatus for measuring the polymerization temperature according to the invention, it was built with the use of assuming the temperature measurement assumptions under the conditions most similar to their occurrence in the direct application of the tested material rial. The thermal insulation chamber has been equipped 2 a heater and a connected temperature sensor with thermoregulator to obtain the temperature output determined by the conditions of mass application acrylic. Polymer temperature gauge sensor is introduced into the tested material.
Koncówka czujnika wprowadzona w badany mate¬ rial jest zabezpieczona oslona z bardzo cienkiej folii aluminiowej, przy czym oslona ta pozostaje w ba¬ danym tworzywie po zakonczonym procesie polime¬ ryzacji.The tip of the sensor inserted into the tested material The rial is protected by a very thin foil cover aluminum, the cover remains in the barrel given material after the finished polymer process drawing.
Czujnik miernika temperatury jest prowadzony pionowo w otworze pokrywy zamykajacej od góry komore termoizolacyjna oraz posiada koncówke termistorowa osadzona w elemencie termoizolacyj¬ nym wykonanym korzystnie ze szkla organicznego.The temperature gauge sensor is guided vertically in the opening of the cover from above a thermal insulation chamber and has an end piece thermistor embedded in the thermal insulation element preferably made of organic glass.
Obudowa komory jest utworzona z materialu ter¬ moizolacyjnego, a ponadto jej wewnetrzne scianki w tym i scianka pokrywy od strony komory sa wylozone warstwa filcu pokrytego oslona z cienkiej folii aluminiowej.The casing of the chamber is made of ter isolation, as well as its internal walls including the wall of the lid from the side of the chamber are lined with a layer of felt covered with a thin guard aluminum foil.
Aparat wedlug wynalazku umozliwia przeprowa¬ dzenie dokladnych pomiarów temperatury polime¬ ryzacji mas akrylowych jako implantatów w wa¬ runkach najbardziej zblizonych do ich stosowania w chirurgii. Otrzymanie obiektywnych wyników pomiarów pozwala na jednoznaczne ustalenie.przy¬ datnosci badanych mas akrylowych dla potrzeb chirurgii.The apparatus according to the invention makes it possible to carry out making accurate measurements of the temperature of the polymer the drawing of acrylic masses as implants in the shaft statements most closely related to their use in surgery. Obtaining objective results measurements allows for unambiguous determination of the point suitability of the tested acrylic masses for needs surgery.
Przedmiot wynalazku jest uwidoczniony w przy¬ kladzie wykonania na zalaczonym rysunku, który101 237 3 przedstawia aparat do pomiaru temperatury w przekroju pionowym.The subject matter of the invention is illustrated in example the execution is shown in the attached drawing, which is 101 237 3 presents a temperature measuring apparatus in vertical section.
Obudowa 1 komory termoizolacyjnej 2 jest wy¬ konana korzystnie ze styropianu, a jej scianki we¬ wnetrzne sa wylozone warstwa 3 korzystnie z fil¬ cu oraz warstwa 4 z cienkiej folii aluminiowej.The housing 1 of the thermal insulation chamber 2 is dimmable It is preferably made of polystyrene and its walls are woven the inside are lined with a layer 3, preferably of a felt cu and layer 4 of thin aluminum foil.
