Description

Technical Field

[0001] The utility model relates to the technical field of respiratory oxygen therapy equipment, in particular to an integrated nasal high-flow respiratory oxygen therapy machine. Background Art

[0002] Oxygen therapy is a common clinical treatment method, especially for critically ill patients, patients with respiratory diseases and patients suffering from hypoxia at high altitudes. In traditional oxygen therapy, oxygen is usually supplied by oxygen tanks or oxygen generators, and then given to patients through masks or nasal cannulas. However, this method has some problems, such as the difficulty in controlling oxygen concentration, insufficient oxygen supply, or unstable oxygen supply.

[0003] In recent years, high-flow nasal breathing oxygen therapy technology has gradually been widely used. This technology generates oxygen through a high-flow oxygen generator and directly administers it to the patient through a nasal cannula, thereby providing a higher oxygen concentration and a larger oxygen flow rate to meet the patient's oxygen inhalation needs. However, most of the high-flow nasal breathing oxygen therapy devices on the market currently have some problems. For example, the equipment is large in size, noisy, has low oxygen concentration, and low oxygen flow rate. These problems have limited the widespread application of high-flow nasal breathing oxygen therapy technology.

[0004] Moreover, traditional nasal high-flow oxygen therapy equipment usually uses oxygen tanks as the source of oxygen, which has problems such as unstable oxygen supply, insufficient oxygen concentration, and the need to frequently replace oxygen tanks. In addition, the use of oxygen tanks also has certain safety hazards, such as oxygen leakage and oxygen tank explosion.

[0005] In addition, in traditional oxygen therapy equipment, the oxygen generator is usually installed inside the equipment, which leads to poor air flow inside the equipment, affecting the working efficiency of the oxygen generator. At the same time, dust, bacteria, etc. inside the equipment may enter the oxygen generator, affecting the quality of oxygen. Moreover, the exhaust gas inside the equipment cannot be discharged in time, which may affect the operation of the oxygen generator. It is inconvenient to plug and maintain the components, and it is difficult to ensure the cleanliness of the components for long-term operation. Utility Model Content

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-8 , see Figure 1-8 A nasal high-flow breathing oxygen therapy integrated machine includes a housing 1 and an oxygen generator 2, a water storage tank 3, and a mixing component assembled in the housing 1, and also includes a nasal catheter 5 plugged into the outside of the housing 1, and the nasal catheter 5 is connected to the mixing component.

A foot pad 14 is mounted on the bottom of the casing 1 to ensure that the casing 1 and the components assembled therein can be stably placed and run stably.

[0043] The oxygen generator 2 adopts a common model on the market. The oxygen generator 2 can separate nitrogen and other impurities in the air through the molecular sieve or membrane separation technology therein, thereby extracting high-concentration oxygen. Then, the generated specific oxygen concentration gas is input into the processing tank 41 through the corresponding oxygen supply branch pipe, and the input amount of the prepared oxygen is determined by the electronic flow meter and electromagnetic thorn switch valve installed thereon.

[0044] It is also possible to connect to a high-concentration oxygen cylinder and a low-concentration oxygen cylinder respectively through the high-oxygen interface 11 and the low-oxygen interface 12, input oxygen of different concentrations into the processing tank 41 through the corresponding oxygen supply branch pipes, and adjust the input amount of high-concentration oxygen and low-concentration oxygen per unit time through the corresponding electronic flow meter and electromagnetic switch valve, so that the mixed oxygen concentration in the processing tank 41 meets the treatment needs.

[0046] The oxygen mixed in the treatment tank 41 is delivered to the patient through the oxygen supply pipe 48 and the nasal catheter 5 to meet the patient's respiratory oxygen therapy needs, and the appropriate oxygen supply is controlled by the electronic flow meter and the electromagnetic switch valve installed thereon.

[0049] The air inlet 22 and the air outlet 23 are mounted on the outside of the casing 1, so that the air inlet 22 can draw air from the external environment into the oxygen generator 2 for oxygen production, and the waste gas generated during the oxygen production process can be discharged into the external environment through the air outlet 23. The air inlet 22 and the air outlet 23 are mounted on different sides of the casing 1 to prevent the waste gas discharged from the air outlet 23 from directly entering the air inlet 22 and affecting the oxygen production efficiency of the oxygen generator 2.

[0050] The design of the dustproof net 24 can prevent dust in the external environment from entering the oxygen generator 2 and affecting the quality of oxygen prepared by the oxygen generator 2.

The driving motor 434 is arranged on the outer side of the processing tank 41 and is dynamically connected to the bottom of the connecting seat 433.

[0061] When the mounting plate 431 is plugged into the top of the connecting seat 433, the two are fixed by fixing bolts arranged in a mirror image, so as to ensure a stable connection between the two and facilitate their disassembly and assembly.

[0062] When the driving motor 434 is running, it can drive the connecting seat 433, the mounting plate 431 and the stirring blade 432 fixed to the mounting plate 431 to rotate at a high speed, thereby achieving efficient mixing of the gas inside the processing tank 41.

[0063] In order to ensure that each oxygen supply branch pipe can be stably connected to the processing tank 41, the following technical solution is provided.

[0064] An oxygen supply main pipe 64 is connected to the top of the upper tank body 411, and the oxygen supply branch pipes include branch pipe No. 1 61, branch pipe No. 2 62, and branch pipe No. 3 63. The two ends of branch pipe No. 1 61 are respectively connected to the high oxygen interface 11 and the oxygen supply main pipe 64, and the branch pipe No. 1 61 is equipped with an electronic flow meter No. 1 611 and an electromagnetic switch valve No. 1 612.
