Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a wall-mounted oxygen concentrator with a quickly detachable compression pump and a quick-detachment method thereof. Background Art

[0002] At high altitudes, the oxygen concentration in the air is low, which can cause hypoxia. As the hypoxia worsens, lips and nails will turn purple, blood pressure will drop, pupils will dilate, and people will fall into a coma. Finally, they will die from breathing difficulties, cardiac arrest, and hypoxia. The diffuse oxygen generator system is a device that improves the human body's environment by increasing the oxygen content (oxygen concentration) in a sealed space (such as a bedroom, office, etc.), allowing the human body to bathe in an oxygen-rich environment, thereby improving the human body's internal respiratory environment and promoting a benign cycle of metabolic processes, so as to alleviate hypoxia symptoms and improve health.

[0003] The applicant has applied for a utility model patent named "Modular internal unit and group-type diffused oxygen generator using the same", with the authorization announcement number CN 214004053 U. The internal unit includes an internal chassis, a compression pump, a silencer, an adsorption tower device, a heat dissipation device, a gas reversing device, and a circuit control device. The side surface of the internal chassis has at least one openable side opening. The interior of the internal chassis forms an internal installation space. The compression pump and the silencer are installed in the internal installation space. The heat dissipation device, the gas reversing device, the adsorption tower device, and the circuit control device are fixedly installed on the outer surface of the internal chassis. This patent solves the problems of complex production and installation of oxygen generators with different flow rates when used in high-altitude areas, and the damage of a single part of the oxygen generator causing the entire machine to be unusable. The group-type diffused oxygen generator can be configured with different numbers of internal units according to customer needs to meet different flow configuration requirements, and the number of internal units can be flexibly adjusted to quickly provide prototypes to meet the needs of the competitive market.

[0004] However, in the process of actual application, it is found that this solution still has the following shortcomings:

[0005] In the above scheme, the internal unit module is used as an integral unit. When the compression pump in the internal unit module needs to be replaced and repaired, the chassis sheet metal of the entire machine and the rear side panel of the internal unit need to be removed, and then the compression pump needs to be taken out from the rear side. The disassembly process is complicated and the workload is large, especially when the internal unit is installed in a chassis mounted on an external wall. When removing the compression pump, the internal unit needs to be lifted out of the chassis as a whole and then removed. Due to the overall weight of the internal unit, it brings great convenience to high-altitude construction.

[0045] The working principle and advantages of the present invention are as follows:

[0046] The internal unit module of the oxygen concentrator is a highly integrated device. The pipelines and electrical cables are connected and integrated internally, and finally the oxygen tube and power cord are led out. After power is turned on, oxygen can be supplied separately. The overall diffusion oxygen concentrator is a combination of multiple internal unit modules, so as to achieve centralized oxygen output. In the prior art, most of the equipment works on flat ground, and the internal unit modules can be taken out by disassembling the chassis during maintenance. The diffusion oxygen concentrator used as a wall-mounted type is installed in outdoor operations at high altitudes, and the disassembly and assembly are extremely difficult, so the equipment must be reduced in weight and disassembled and assembled, otherwise it cannot be taken out. Limited by the highly integrated design, the present invention innovatively proposes an upper and lower split solution, that is, part of the components of the internal unit are concentrated in the upper unit, and the other part of the components are concentrated in the lower unit, and a gas circuit connector and a power cord connector are provided for easy quick disassembly. With this design, the present invention can realize split operation regardless of disassembly or installation. For example, during disassembly, the combination state of the upper unit and the lower unit can be quickly released through the cleverly designed quick-release structure, and then the upper unit is taken out first, and then the lower unit is taken out. Compared with the prior art, the present invention greatly reduces the single lifting weight through split disassembly, reduces the difficulty of high-altitude operations, and improves operational safety. At the same time, the disassembly of the upper unit and the lower unit and the removal of the compression pump from the lower unit will become faster and more convenient, greatly reducing the workload.

[0047] In the further design, thanks to the design of the wall-mounted platform and the operating position on the platform, a practical and safe operating space is provided for the operator, making it convenient for the operator to perform operations more easily while ensuring safety.

6. The wall-mounted oxygen concentrator with a quickly detachable compression pump according to claim 5, characterized in that: The internal machine module (45) comprises at least two groups, and each group of internal machine module (45) is arranged in parallel in the machine case (27).

7. The wall-mounted oxygen concentrator with a quickly detachable compression pump according to claim 5, characterized in that: An operating position (33) is provided on one side of the wall-mounted platform (26) corresponding to the machine box (27) for an operator to stand and operate the oxygen concentrator.

8. The wall-mounted oxygen concentrator with a quickly detachable compression pump according to claim 5, characterized in that: The rear side panel of the chassis (27) is provided with a plurality of air inlets (31) corresponding to the air inlet frame (23) of the upper unit, and the front side panel of the chassis (27) is provided with a plurality of nitrogen exhaust ports (32) corresponding to the nitrogen exhaust silencer (4) of the lower unit.

9. A quick disassembly method for a wall-mounted oxygen concentrator capable of quickly disassembling a compression pump, characterized in that: Used to realize the quick disassembly of a wall-mounted oxygen concentrator with a quickly detachable compression pump according to any one of claims 1 to 8, the disassembly method comprising: Step 1: Power off the internal unit module (45) through the electrical control box (30) and open the protective cover plate on the chassis (27); Step 2: disconnect the line connecting the pump power line connector (10) and the power terminal block (29), and unplug the oxygen outlet pipe from the oxygen outlet terminal block (35); and, Disconnect the gas line joint between the upper unit and the lower unit; Step 3: Lift the upper unit upwards to separate it from the lower unit; Step 4: lift the lower unit upwards and remove it from the chassis (27); Step 5: Disassemble and remove the compression pump (3) from the lower unit; The way to disconnect the gas line joint between the upper unit and the lower unit is: Loosen the two gas circuit joints, and remove the second nitrogen discharge pipe (19) and the second gas outlet pipe (18) of the upper unit from the two gas circuit joints of the lower unit, respectively, to disconnect the gas circuits of the upper unit and the lower unit; The way to disconnect the gas line joint between the upper unit and the lower unit is: Pulling out the male connectors of the two gas path connectors from the female connectors, and the pulling out action is performed simultaneously with the separation action of the upper unit and the lower unit; In step five, the first air outlet pipe (7) is first removed from the first air path connector of the lower frame (2) to disconnect the air path of the compression pump (3); Then, one end of the compression pump (3) is lifted so that its bottom is separated from one of the pair of positioning rods (34) at the bottom of the lower frame (2); then, the other end of the compression pump (3) is lifted so that the bottom of the compression pump (3) is separated from all the positioning rods (34), thereby achieving separation of the compression pump (3) and the lower frame (2).
