Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a lung function trainer. Background Art

[0002] The lungs are the respiratory organs of the human body, located in the chest cavity, one on each side, covering the heart. After people develop respiratory symptoms and undergo surgery, they need to undergo lung function recovery training, so they need to use a lung function trainer.

[0003] The existing pulmonary function trainer is inconvenient to use and cannot adaptively adjust the intensity of breathing training according to the actual condition of the patient's lungs. There are certain limitations in its use. For this reason, we propose a pulmonary function trainer. Utility Model Content

[0004] The purpose of the utility model is to provide a pulmonary function trainer to solve the problem that the existing pulmonary function trainers proposed in the above-mentioned background technology are relatively inconvenient to use, cannot adaptively adjust the breathing training intensity according to the actual condition of the patient's lungs, and have certain limitations in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pulmonary function trainer, comprising a trainer main body, the trainer main body comprising an outer shell, one end of the outer shell having an opening and a shell cover movably arranged in the opening, a gas pipeline and an air inlet and outlet pipe are installed through the outer shell, a breathing mask is movably arranged at the end of the gas pipeline away from the outer shell, a protective cylinder is movably arranged at the end of the air inlet and outlet pipe away from the outer shell, a mounting ring is fixedly installed on the inner wall of the outer shell, a plurality of springs are fixedly installed on the side of the mounting ring, a piston plate is movably arranged at the end of the spring away from the mounting ring, a threaded rod is threadedly installed on the shell cover, a hand wheel and an adjusting top plate are respectively fixedly installed at both ends of the threaded rod, the adjusting top plate is fitted on the side of the piston plate, a handle 1 is fixedly installed on the outer surface of the outer shell, and a handle 2 is fixedly installed on the side of the shell cover.

[0006] The above scheme is adopted, by setting a threaded rod to be used in conjunction with a spring, an adjusting baffle and a piston plate, the spring is always in a deformed state, and the rotation of the threaded plate can drive the adjusting baffle to move, and then adjust the initial position of the piston plate, thereby controlling and adjusting the deformation of the spring. The larger the deformation, the more difficult it is for the piston plate to move, indicating that the required breathing force is greater. Therefore, it can be adaptively adjusted according to the patient's own lung function condition, and the operation and adjustment are convenient to improve universality. By setting a gas pipeline to be used in conjunction with a connecting pipe, the disassembly and assembly of the breathing mask is convenient. One person has one breathing mask to avoid cross infection. By setting a protective tube to be used in conjunction with the inlet and outlet pipes and the dust filter, the inlet and outlet gases can be filtered to prevent dust from entering the shell, which has a good dustproof effect. By setting a shell cover to be used in conjunction with the shell, and the bolts to be used in conjunction with the mounting plate, the subsequent disassembly, assembly and replacement of the piston plate in the shell are convenient, thereby improving functional diversity.

[0007] As a preferred embodiment, an observation port is provided on the outer shell, and a transparent observation plate is fixedly installed in the observation port.

[0008] By adopting the above scheme, the movement position of the piston plate can be accurately controlled by using the observation port in conjunction with the head and face observation plate.

[0009] As a preferred embodiment, a telescopic rod is fixedly installed inside the spring, and a mounting plate is fixedly installed on the ends of the spring and the telescopic rod. A threaded groove is provided on the side of the mounting plate, and a through hole is provided on the piston plate at a position opposite to the mounting plate, and a bolt is passed through the through hole, and the bolt is used in conjunction with the threaded groove.

[0010] By adopting the above scheme, the setting of the telescopic rod can support the spring to avoid elastic bending, and can provide limited support for the piston plate so that the piston plate will not tilt or shake when moving. The setting of the bolts is used in conjunction with the mounting plate to facilitate the disassembly and assembly of the piston plate.

[0011] As a preferred embodiment, the outer surface of the connecting pipe, the outer surface of the shell cover and the outer surfaces of the inlet and outlet pipes are all provided with external threads, the inner wall of the gas channel, the inner wall of the shell and the inner wall of the protective tube are all provided with internal threads, and the external threads and internal threads at corresponding positions are used in combination.

[0012] By adopting the above scheme, the external thread is used in conjunction with the internal thread, so that the disassembly and assembly operations of the breathing mask, the protective tube and the shell cover are convenient.

[0013] As a preferred implementation, a dust filter is fixedly mounted on the inner wall of the protective cylinder.

[0014] With the above solution, the dust filter can filter the gas entering the shell to prevent dust from entering, thus achieving a good dust-proof effect.

[0015] As a preferred embodiment, the piston plate is located in the middle of the gas pipeline and the inlet and outlet pipes.

[0016] By adopting the above scheme, there will be no crossover phenomenon during exhalation and inhalation.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The pulmonary function trainer is used by setting a threaded rod in conjunction with a spring, an adjustment baffle and a piston plate. The spring is always in a deformed state. The rotation of the threaded plate can drive the adjustment baffle to move, and then adjust the initial position of the piston plate, thereby controlling and adjusting the deformation of the spring. The larger the deformation, the more difficult it is for the piston plate to move, indicating that the required breathing force is greater. Therefore, it can be adaptively adjusted according to the patient's own lung function status, and the operation and adjustment are convenient, which improves universality.

[0019] The pulmonary function trainer is provided with a gas pipeline for use with a connecting pipe, which facilitates the disassembly and assembly of the breathing mask. Each person is provided with a breathing mask to avoid cross infection. A protective tube is provided for use with the inlet and outlet pipes and the dust filter to filter the inlet and outlet gases to prevent dust from entering the shell, thereby achieving a good dust-proof effect. A shell cover is provided for use with the shell, and bolts are provided for use with the mounting plate to facilitate subsequent disassembly, assembly and replacement of the piston plate in the shell, thereby improving functional diversity.

The setting of the bolt 20 is used in conjunction with the mounting plate 19, which is convenient for disassembly and assembly of the piston plate 11.

[0030] The outer surface of the connecting pipe 5, the outer surface of the shell cover 3 and the outer surface of the air inlet and outlet pipes 7 are all provided with external threads, and the inner wall of the gas channel, the inner wall of the shell and the inner wall of the protective tube 8 are all provided with internal threads.
