The invention relates to the field of medical facilities, in particular to a full-automatic breathing bag pressing device. The device comprises a driving part, a base plate and boxes fixed to the twoends of the base plate. Two extrusion plates for extruding a breathing bag are arranged between the two boxes. A connecting rod is fixedly arranged on the extrusion plates. The end, away from the extrusion plates, of the connecting rod penetrates into the boxes and is connected with a movable plate, a stretchable reset rod is connected between the movable plate and the inner walls of the boxes, cams for pushing the movable plate are fixed to the interiors of the boxes, and the cams are driven by the driving part; the device has the advantages that by arranging a cam mechanism, the bag is automatically pressed, and labor amount of nurses is lowered; the relative positions of the cams and the movable plate are adjustable, the single-pressing oxygen output amount is adjustable, and the patient can conveniently use the device; due to the fact that the driving mechanism is low in price and simple in structure, the cost of the device is greatly lowered, and a large number of the devices canbe configured in a hospital conveniently or patients can purchase and use the device conveniently.

The invention relates to the respiratory organs protection technical means that provide human with life support in the atmosphere unsuitable for breathing. Insulating breather with closed breathing mixture circulation loop (self-contained self-rescue, SCSR) is equipped with a cylinder (15) containing pressurized oxygen. The breather has increased effectiveness of the treatment of the exhaled gas mixture and improved quality of the inhaling gas mixture by using the breathing mixture circulation loop of the present invention and using means for simultaneous mechanical pressing on the breath-out bag (4) and the breath-in bag (8) and the additional cooling.

A system includes a closed-circuit respirator (1) with a breathing mask (2), a closed breathing circuit, which leads from the breathing mask via an exhalation tube (3), a lime cartridge (4) for binding CO2, a spring-loaded breathing bag (5) and an inhalation tube (7) to the breathing mask. A pressurized oxygen tank (11) is connected to the circuit via a constant dispensing unit (8) and to the breathing bag via a minimum flow control valve (9), which opens upon a collapse of the breathing bag (lack of breathing gas in the circuit) and fills the breathing bag from the oxygen tank. A pressure sensor (12) detects the pressure in the oxygen tank. A constant dispensing unit introduces oxygen with a volume lower than a mean oxygen volume demand. A monitoring device (13-15) calculates a quantity of oxygen consumed and still remaining from the detected pressure and an initial pressure value.

The invention provides bacteria-enzyme synergistically fermented feed containing stevia rebaudiana residues and an application of the feed. The feed comprises the following raw materials in parts by mass: 38-43 parts of the stevia rebaudiana residues after pre-fermentation with aspergillus niger, 6-12 parts of corn, 4.5-12 parts of soybean meal, 12-20 parts of DDGS, 11-20 parts of rice bran meal,0-15 parts of bran, 0-8 parts of stone powder, 0-0.3 part of 30% betaine, 0-0.7 part of calcium hydrophosphate, 0-0.5 part of sodium chloride and 1-2 parts of glucose. A complex microbial agent accounting for 0.05-0.1% of the stevia rebaudiana residues is added to be mixed uniformly, a mixture is put into a breathing bag, the breathing bag is sealed, and fermentation is performed at 25-30 DEG C for 5-7 days.

Disclosed is a breathing bag, comprising three components, A, B and C. The weight ratio of the three components, A, B and C are 100 : 90 to 400 : 1 to 15, wherein component A comprises PVC, component B comprises a plasticizer, and component C comprises a stabilizer. Component A is a powder, component B is a liquid, and component C is a liquid or a powder. The breathing bag is mainly made of PVC, and a certain amount of a plasticizer and a stabilizer are added, so that the breathing bag does not contain natural rubber latexes to which a patient may be allergic; and the production process does not require the use of talcum powder and ammonia, thus reducing the pollution of the environment.
