The bag, mainly for an electrocardiography (ECG) apparatus, contains a multilayer cover 1, a multilayer bottom 2 and a multilayer closed side wall 3, permanently fixed to the bottom 2, the cover 1 and side wall 3 are connected by a longitudinal hinge 4 and are each made with outer layers 5, 6 made of synthetic fabric, between which there is an inner cushioning protective layer 7 made of elastic material. The bottom 2 is made with outer layers 5, 6 of synthetic fabric, between which are located an inner shock-absorbing protective layer 7 and a rigid protective layer 8. The bag is equipped with a zipper 9 installed along the contour of the lid 1 and the side wall 3. The bag is provided with the possibility fixing with a multi-layer flat pressure piece 10 (longitudinal partition) made with outer layers 5, 6 of synthetic fabric, between which there are a shock-absorbing protective layer 7 and a hard protective layer 8. The bottom 2 is equipped with one end of the pressure belts sewn into it for fixing the pressure parts 10 and, thus, apparatus 17. The first and second belts 11, 12 are sewn into the bottom 2 from the side of the hinge 4, and the third belt 13 is from the opposite side of the bottom 4 to the hinge 4. The lashing belts 11, 12, 13 are each equipped with a fastener. Velcro 14 at its free end, and the pressing part 10 is made from one of its edges with two through slots 15, 16, in which the first and Ory pressure belts 11, 12, and is equipped on the side facing the lid 1, with the reciprocating Velcro fasteners 18 for the Velcro fasteners 14 of each of the pressure belts 11, 12, 13. The design of the bag for the ECG apparatus provides its secure clamped position using multi-layer the bottom and the clamping part, which contributes to the safety of the fragile device - the ECG apparatus. At the same time, the body reliably protects the device from the effects of ultraviolet rays and moisture. The design provides the ability to quickly deploy the ECG device to
