The mechanical model of the lungs comprises frame 1, two furs 2, fixed bar 3 fixed to frame 1, a movable, hingedly fixed bar 4, spring 5 for bringing together the fixed and movable bar 3 and 4, with one end connected to the movable a strap 4, and another with a fixed strap, a device for adjusting the force of the spring 5, made in the form of a pair of guide rails 6 and 7 separated from each other, the rail 6 being mounted on the movable strap 4, and the rail 7 on the frame 1, and clamping device 8, movably fastened relative to the guide rails 6 and 7, calibrated scale 9, located along the yush direction; its rail 6, bracket 10 mounted on the movable bar 4, adjustable stop I in the form of a wire fixed to the mobile end 1 with one end and the other the strap 4, the device 12, the neutralizing effect of the weight of the movable strap 4 in the form of a spring attached at one end to the bracket, and the other to the frame 1 with the possibility of mixing, the device 13 to prevent the irregular protrusion of the fur in the form of wire, tightly all the folds of fur 14, the retaining device 15 in the form of a ring, installed between the plates 3 and 4, the indicator 16 of the gas volume, which is a panel curved in accordance with the arcuate path of movement of the free end of the movable plate 4 and suspended by means of a hinge 17 on the frame 1 with the possibility of mixing in a horizontal position, and also has clamps 18 and a shock absorber 19, fittings 20 for supplying gas to furs connected by a tee 21, a pressure gauge 22 for determining the pressure in the fur 2.
Модель работает следующим образом.The model works as follows.
При заданной впускной мощности аппарата раздувание мехов 2 пропорционально выбранному сопротивлению штуцеров 20 и сопротивлению пружины 5. Объем мехов считываетс визуально по положению верхпей грани подвижной планки 4 по отношению к графикам, нанесенным на панели индикатора 16 объема газа, а конкретное давление устанавливаетс по показани м манометра 22. Дл установки необходимого сопротивлени мехов последние полностью сжимаютс , верхнее зажимное приспособление 8 устанавливаетс в нужное положение, определ емое по шкале 9 на рельсе 6, затем строго по вертикали к нему устанавливаетс нижнее приспособление 8 на рельсе 7 и оба приспособлени фиксируютс винтами 23. После этого модель готова к работе . При необходимости транспортировани панель индикатора 16 складываетс в горизонтальном положении поверх подвижных планок 4. Аппарат снабжен амортизаторами 24, позвол ющими ставить его на нижнюю или торцевую сторону. For a given intake power of the apparatus, the fur of the bellows 2 is proportional to the selected resistance of the unions 20 and the spring resistance 5. The volume of the bellows is visually read by the position of the top face of the movable bar 4 in relation to the graphs plotted on the gas volume indicator panel 16, and the specific pressure is measured by the pressure gauge 22. To set the required resistance of the bellows, the latter are fully compressed, the upper clamping device 8 is set to the desired position, determined on a scale 9 on the rail 6 Then, the lower fixture 8 is mounted vertically on it to the rail 7 and both fixtures are fixed with screws 23. After this, the model is ready for operation. If it is necessary to transport, the indicator panel 16 is folded in a horizontal position over the movable bars 4. The device is provided with shock absorbers 24 enabling it to be placed on the lower or end side.
