A PROCESS FOR THE PREPARATION OF IMPROVED CERVICAL DILATORS AND CERVICAL DIALATORS THUS PREPARED

摘要

A process for the preparation of improved cervical dilators comprising encapsulating compressed rods or cores of Plantago ovata seed husk in a cylindrical cloth tube made of a single layer of fine cloth closed from inside with a thin layer of a absorbent fine cellulose powder suspended in aqueous gum acacia solution, further compressing the same to form a hard cylindrical shaped stick, packing the said stick in colourless polythene or glass tube and sterilizing the same exposure to gamma radiations characterized in that Planta, ovata (Psyllium) seed husk and the like plant or synthesis materials capable of swelling on contact with moisture to form tenacious mucilage used are admixed with a distinct grating agent and an effervescent powder made of a made organic acid, alkali bicarbonate or an ion-exchange resin.
