Embodiment 1

[0036] Such as figure 1 As shown, the ventilator includes a first airbag 1 and a second airbag 2 whose internal space can expand and shrink, a valve group, a molecular sieve tank 4, an oxygen storage tank 5, an air-oxygen mixer 6, and a mask integrated air leakage valve 7;

[0037]The first airbag 1 has an air inlet and an air outlet, the air inlet is provided with a first one-way valve 11, and the air outlet is provided with a third one-way valve 12, and the first airbag 1 is mixed with air and oxygen through the third one-way valve 12 The air-oxygen mixer 6 mixes the oxygen from the oxygen storage tank 5 and the air from the first air bag 1, and the air-oxygen mixer 6 is connected with the humidifier 8 through the second one-way throttle valve 61, and the humidifier 8 is connected with the mask integrated air leakage valve 7, and the air-oxygen mixer 6 is provided with an overflow valve 62 as a guarantee for exhalation safety.

[0038] The second airbag 2 has an air inlet a...

Embodiment 2

[0055] Such as Figure 5 As shown, the difference between this embodiment and embodiment one is that the number of molecular sieve tanks 4 is different:

[0056] In this embodiment, there are two molecular sieve tanks 4. Correspondingly, there are two two-position two-way linkage one-way pressure valves 3 and two throttle valves 41; a one-one two-way switching valve 42 is also included. After the second air bag 2 is connected to a one-position two-way switching valve 42, two two-position two-way linkage one-way pressure valves 3 are respectively connected, and the two-way linkage one-way pressure valve 3 is connected to a molecular sieve tank 4, and the top connection joint of the molecular sieve tank 4 Throttle valve 41, both throttle valves 41 are connected to oxygen storage tank 5.

[0057] Such as Figure 6(a) , 6(b) As shown, the one-position two-way switching valve 42 includes a touch lever 421, a return spring 422, a one-way gear 423, a first rack 424, and a two-posi...

Embodiment 3

[0067] Such as Figure 8 , Figure 9 As shown, the difference between the present embodiment and the first embodiment lies in that the driving mode of the extruding plate 9 is different.

[0068] In this embodiment, the extruding plate 9 has a second rack 91 on the outside, and also includes a fixed driving gear 92 , and the second rack 91 meshes with the driving gear 92 .

[0069] Such as Figure 8 As shown, the driving gear 92 rotates clockwise, which drives the extrusion plate 9 to move to the right, compresses the second airbag 2, and expands the first airbag 1; Figure 9 As shown, the driving gear 92 rotates counterclockwise, driving the pressing plate 9 to move left, compressing the first airbag 1 and expanding the second airbag 2 .

[0070] In addition to realizing the left and right movement of the extrusion plate 9 through gear meshing, it can also be realized through mechanical structures such as chains, belts, and reciprocating screws.

Abstract

The invention discloses a breathing machine which comprises a first air bag, a second air bag, a valve bank, one or more molecular sieve tanks, an oxygen storage tank, an air-oxygen mixer and a mask integrated air leakage valve. An extrusion plate is arranged between the second air bag and the first air bag, an air outlet of the second air bag is connected with a molecular sieve tank, two ends ofthe molecular sieve tank are respectively provided with a nitrogen outlet and an oxygen outlet, the oxygen outlet is connected with an oxygen storage tank, and the internal space of the second air bagis compressed and expanded once and synchronously adsorbed and desorbed with a molecular sieve in the molecular sieve tank once; an air outlet of the first air bag is connected with an air-oxygen mixer which is connected with a mask integrated air leakage valve. The breathing machine has the beneficial effects that extremely low cost is added to a common breathing machine, so that the breathing machine has an oxygen production function, the breathing machine can supplement a certain amount of oxygen at any time and can also be powered off under special conditions, and the emergency or low-cost requirement that part of users need to inhale rich oxygen is met.

Description

technical field [0001] The invention relates to a breathing system, in particular to a ventilator. Background technique [0002] The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. However, ordinary ventilators only help people to ventilate and breathe spontaneously, and do not have the function of oxygen production. , and some patients, such as patients with chronic obstructive pulmonary disease, have carbon dioxide retention, so they need to use a ventilator to expel carbon dioxide, and at the same time need extra oxygen to supplement the body's oxygen saturation; for patients with severe lung failure, there is no way to give the body The tissue cells in the body supply enough oxygen for metabolism, and a certain concentration of oxygen needs to be added while using the ventilator. [0003] Pressure swing adsorption (abbreviated as PSA), as a gas separation technology, ha...
