The invention relates to the laboratory<br />
equipment for registration of oxygen consumption by the<br />
laboratory animals and can be used in the experimental<br />
biology, medicine, physiology, ecology etc.<br />
The device for registering the oxygen consumption by<br />
laboratory animals comprises a chamber with<br />
temperature-controlled microclimate (1), inside which<br />
there are placed a chamber for the laboratory animals<br />
(2), provided with a st<strong>op</strong>per (18) and a thermometer (9),<br />
an oxygen reservoir (3), a vessel for CO2 adsorption (4),<br />
a vessel for water (5) and a burette-manometer (6). At<br />
the same time, the walls of the chamber with<br />
microclimate (1) are heat-insulated.<br />
Outside the chamber with microclimate (1) it is installed<br />
a thermal control device (11), which is connected to a<br />
contact thermometer (19). The vessel for water (5) is<br />
connected to a filler tube, the free end (21) of which is<br />
Description EN<br />
placed outside the chamber with microclimate (1). The<br />
burette-manometer (6) is connected by means of a nipple<br />
to the<br />
contact device (7), consisting of a plug (27), installed in<br />
the upper part of the oxygen reservoir (3), contacts of<br />
silver wire (31) and a pipette (29), which is connected to<br />
the burette-manometer (6). Inside the pipette (29) there<br />
is placed a wood chip (33). The contact device (7) is<br />
connected to a calculator for fixing the number of dr<strong>op</strong>s<br />
(8), according<br />
to which it is determined the quantity of the consumed<br />
oxygen. The burette-manometer (6) is connected to the<br />
oxygen reservoir (3) by means of a connecting branch<br />
(12). The vessel for CO2 adsorption (4) is filled with<br />
chips of organic glass. At the bottom of the chamber<br />
with microclimate (1) it is installed a microfan (13) and<br />
an illumination source (14).<br />
