RATIONAL SPENDING OF MEDICATIONS DURING INTRODUCTION OF MEDICINAL SUBSTANCES INTO SUBTANOUS SPACE BY MEANS OF DOSER Russian patent published in 2008 - IPC A61F9/07 A61M5/172 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely, to ophthalmology, and concerns methods of introduction of medicinal substances in eye tunics and media. Method ensures rational (economical) spending of medications (mixtures) during introduction of medicinal substances by means of doser into subtaneous space due to automatic regulation of mixture concentration in lesion focus. Implant, consisting of strip of collagen sponge 15x10 mm in size and connected with it polychlorvinyl catheter, is introduced into subtaneous space. In sponge two microelectrodes 1.5x1 mm in size, with output from catheter for pickup of potential difference (of electric signal), whose value changes depending on concentration of medicinal mixture in subtaneous space, are placed. Depending on level of electric signal automatic control of operational mode of electronic portable doser "НДЛ" - 3, adapted for use in ophthalmology, is carried out automatically.

EFFECT: ensuring rational spending of medications during introduction of medicinal substances by me4ans of doser into subtaneous space.
