Abstract: front page image
(EN)A pneumatic tocodynamometer ("pTOCO") (10) having a guard-ring (13) with a thin elastic membrane (18) stretched across a shallow spherical depression (12) trapping a small volume of air in the center of the guard-ring (13). A pressure transducer (17) may be molded into the body 11 of the pTOCO (10). In an alternative embodiment, the air volume beneath the membrane (18) of the pTOCO (10) may be connected via a low volume air conduit (14, 15) to a separate pressure transducer (16).
(FR)L'invention porte sur un tocodynamomètre pneumatique (« pTOCO ») (10) ayant un anneau de garde (13) muni d'une fine membrane élastique (18) tendue en travers d'une dépression sphérique peu profonde (12) qui renferme un petit volume d'air au centre de l'anneau de garde (13). Un transducteur de pression (17) peut être moulé dans le corps (11) du pTOCO (10). Dans une variante, le volume d'air sous la membrane (18) du pTOCO (10) peut être relié à un transducteur de pression séparé (16) par un conduit d'air de petit volume (14, 15).
