Abstract

An incubator with a double glazed wall that promotes regulation of sound pressure levels and temperature levels the incubator, using an insulated glass unit. The canopy of the incubator has at least one insulated glass unit. This unit includes at least one first inner glass and at least one second external glass. The inner and external glasses are spaced by a spacer, and are characterized by an inner atmosphere confined within the canopy and an external atmosphere.

said external glass is characterized by thickness W_{external glass};

said glasses separate between at least three different atmospheres;

a first atmosphere (21) within said canopy;

a second atmosphere (22) between said inner and external glasses; and

, a third atmosphere (23) outside said canopy;

said second atmosphere (22) comprises a gas;

said IGU is characterized by U-factor value U (W/m²K) and a Noise Standardized Level Difference (DnT) (dB);

said IGU is adapted to provide said canopy with sound and thermal insulation by means of at least one element selected from a group consisting of (a) said W_{inner glass};

(b) said W_{external glass};

(c) said U-factor value, (d) said Noise Standardized Level Difference (DnT); and

any combination thereof; and

at least one vacuum mechanism (VIG), adapted to provide vacuum into the space between said inner and external panels;

wherein said U-factor and D_nT are provided according to Formula I and Formula II, such that said IGU is configured to (i) avoid sound pressure levels in said inner atmosphere from exceeding 45 dB, and (ii) to increase temperature regulation in said inner atmosphere, such that temperature interval in not greater than 1°

C. for air controlled transport incubators and not greater than 0.5°

C. for baby controlled transport incubators.

2. The incubator of claim 1, wherein said IGU comprising a gas space of about 16 to about 19 mm when measured at the center of the IGU.
