Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a simple breathing trainer. Background Art

[0002] A breathing trainer is an instrument used to train the lungs, exercise lung function and breathing ability.

[0003] At present, the structures of respiratory trainers include trainers with a respiratory mask structure and trainers with a handheld structure. For the respiratory trainer with a respiratory mask structure, it must be tied to the human face and seal the human nasal cavity and oral cavity. The patient inhales through the nasal cavity and exhales through the mouth to perform inhalation and exhalation training. This training method is relatively harsh and is suitable for training patients with chronic obstructive pulmonary disease.

[0004] Handheld training devices, in which breathing is performed through oral inhalation and exhalation, typically consist of a T-shaped tube. Of the three openings, two openings on the same axis serve as the inlet and outlet, respectively. The remaining opening, the third, corresponds to the oral cavity. The inlet and outlet are not connected to each other, but each connects to the third opening, forming an L-shaped inlet and outlet channel. To achieve progressive lung function training, adjustment mechanisms are provided at the inlet and outlet, respectively. These adjustment mechanisms typically employ a gear-and-disc mechanism. The gears drive the dial to rotate, adjusting the area of ​​the dial obstructing the inlet and outlet, respectively, thereby adjusting the resistance during inhalation or exhalation to meet the training requirements. While this handheld training device is convenient to carry, the inclusion of two adjustment mechanisms increases its complexity. Furthermore, the L-shaped inlet and outlet channels can affect airflow and training effectiveness. Utility Model Content

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, a simple breathing trainer includes a tube body 1. The tube body 1 generally has a Rafale tube structure with large ends and a narrow middle. For ease of description, one large end is the front end, and the other large end is the rear end, corresponding to the human oral cavity. A partition 6 is radially disposed in the front of the tube body 1. The partition 6 divides the interior space of the tube body 1 into two disconnected parts. The space behind the partition 6 is the airway 13, the rear end of which extends out of the tube body 1 to form an opening. The space in front of the partition 6 includes an air outlet cavity 11 and an air inlet cavity 12. The air outlet cavity 11 and the air inlet cavity 12 are arranged side by side in the radial direction of the tube body 1 and are disconnected from each other. The partition 6 is provided with an outlet channel 14 that connects the outlet cavity 11 and the air duct 13, and an inlet channel 15 that connects the inlet cavity 12 and the air duct 13. The outlet channel 14 and the inlet channel 15 are each provided with a corresponding one-way ventilation structure 2. The one-way ventilation structure 2 is preferably a fish-mouth valve or a silicone duck-bill valve or a one-way valve. In this embodiment, the fish-mouth valve is used as an example for illustration. The outlet channel 14 and the inlet channel 15 are each provided with one-way ventilation. The outlet cavity 11 and the inlet cavity 12 are each provided with a matching air vent 5 on the side facing away from the partition 6, so that the outlet cavity 11 and the inlet cavity 12 are respectively connected to the outside world. In the present utility model, the air vent 5 of the outlet cavity 11 is provided opposite to the outlet channel 14, and is connected to the outlet channel 14 through the corresponding fish-mouth valve.
