Description

Technical Field

[0001] This utility model relates to the field of lung function training technology, specifically a thoracic surgical lung function training and rehabilitation device. Background Technology

[0002] In the field of thoracic surgery, after surgical treatment of lung diseases, patients often experience a decline in lung function due to surgical trauma and lung tissue damage. Effective pulmonary function training is of great significance for patients to restore normal respiratory function and reduce the risk of pulmonary complications. Currently, in clinical practice, a cuff device with a one-way valve is commonly used to assist patients in pulmonary function training. Patients inhale into the cuff, and the one-way valve allows gas to flow unidirectionally into the cuff, thereby exercising lung muscles and enhancing respiratory function.

[0003] However, existing pulmonary function training and rehabilitation devices of this type have significant drawbacks. Because the one-way valve has a fixed specification, the blowing force required to open it is constant, making it difficult to meet the rehabilitation needs of different patients. For example, for patients who are weak after surgery and have severely impaired respiratory function, the blowing force required by the fixed-specification one-way valve is too great, which may prevent the patient from effectively completing the exercise or even cause discomfort due to excessive force. Conversely, for patients who are recovering well and need to increase the intensity of their exercise, the fixed opening force of the one-way valve is insufficient to provide adequate exercise intensity, affecting the rehabilitation effect. Therefore, developing a thoracic surgical pulmonary function training and rehabilitation device that can adjust the exercise intensity according to individual patient differences has become an urgent problem to be solved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a thoracic surgery lung function exercise and rehabilitation device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] The connecting tube is connected at one end to the airbag;

[0008] A one-way flow component includes a sealing plate fixed inside a connecting pipe to prevent gas flow. The sealing plate has a vent hole for gas to pass through. A sealing cone that blocks the vent hole when not inflated is slidable on the side of the sealing plate near the airbag. The sealing cone is provided with a return spring that resets itself after inflating.

[0009] The elastic adjustment component includes a connecting rod that changes the compression of the return spring by moving its position, and the connecting rod is provided with a limiting bolt for limiting its position.

[0010] Preferably, the tip of the sealing cone is far from the airbag, and the tip of the sealing cone is provided with a force-bearing hole for bearing gas.

[0011] Preferably, a guide groove is formed on the inner wall of the connecting pipe along its axial direction, and a guide plate with its free end sliding inside the guide groove is fixed on the sealing cone.

The inner wall of the collar slides in fit with the curved wall of the annular cavity, and the end of the connecting rod away from the reset spring is fixed on the collar.

[0013] Preferably, the end of the connecting tube away from the airbag is connected to an air blowing head, and the air blowing channel inside the air blowing head is directly opposite the sealing cone.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model. Example

[0022] like Figure 1-3 As shown, a thoracic surgical pulmonary function training and rehabilitation device includes:

[0023] Airbag 1, with an air vent provided on it;

[0024] Connecting tube 2, one end of which is connected to airbag 1;

[0025] A one-way flow component includes a sealing plate 21 fixed inside the connecting pipe 2 to prevent gas flow. The sealing plate 21 has a vent hole for gas to pass through. A sealing cone 24 that blocks the vent hole when not inflated is slidable on the side of the sealing plate 21 near the airbag 1. The sealing cone 24 is provided with a return spring 28 that resets it after inflating.

[0026] The elastic adjustment component includes a connecting rod 29 that changes the compression of the return spring 28 by moving its position, and the connecting rod 29 is provided with a limiting bolt 27 for limiting its position.

[0027] The problem with existing technology is that when patients are performing pulmonary function rehabilitation exercises, they can blow into an air bag with a one-way valve. Although the one-way valve allows the gas blown out by the patient to flow into the air bag in one direction, the one-way valve has a fixed specification and cannot meet the rehabilitation exercise needs of different patients.

[0028] This invention, by setting an elastic adjustment component, can adjust the compression of the return spring 28 inside the one-way flow component according to the degree of air blowing required by different patients, thereby enabling different patients to use different levels of lung function training and rehabilitation devices.

[0029] The tip of the sealing cone 24 is far away from the airbag 1, and a force-bearing hole for bearing gas is provided on the tip of the sealing cone 24.

[0030] By providing a force-bearing hole at the tip of the sealing cone 24 to withstand the gas, when air is blown into the sealing cone 24, the sealing cone 24 can withstand the blowing force of the gas more easily due to the opening of the force-bearing hole, making it easier for the sealing cone 24 to detach from the vent hole on the sealing plate 21, thereby forming a channel for gas flow and allowing the gas to enter the interior of the airbag 1.

[0031] A guide groove 22 is provided on the inner wall of the connecting pipe 2 along its axial direction, and a guide plate 23 with its free end sliding inside the guide groove 22 is fixed on the sealing cone 24.

[0032] By setting the guide groove 22 and the guide plate 23, the sealing cone 24 can be guided, so that the sealing cone 24 can accurately seal the air hole on the sealing plate 21 when no air is blown in.

[0033] An annular cavity 25 is provided on the outer periphery of the connecting pipe 2. A collar 26 is provided inside the annular cavity 25. The inner wall of the collar 26 slides with the curved wall of the annular cavity 25. The end of the connecting rod 29 away from the return spring 28 is fixed on the collar 26.

[0034] The end of the connecting pipe 2 away from the airbag 1 is connected to an air blowing head 3, and the air blowing channel inside the air blowing head 3 is directly opposite the sealing cone 24.

[0035] When lung function training is required, air is blown into the airbag 1 through the end of the connecting tube 2 away from the airbag 1. At this time, the air pressure in the cavity formed by the connecting tube 2, the sealing plate 21, and the sealing cone 24 increases. The gas will squeeze the sealing cone 24 to move closer to the airbag 1. At the same time, the return spring 28 will contract and shorten. A channel for gas flow will be formed between the sealing cone 24 and the inner wall of the vent hole on the sealing plate 21, allowing the gas to enter the airbag 1 through the channel, thereby inflating the airbag 1. Lung function training is achieved by blowing air. In addition, when no air is blown, due to the elasticity of the return spring 28 and the presence of gas in the airbag 1, the sealing cone 24 will be squeezed to completely block the vent hole on the sealing plate 21, preventing the gas inside the airbag 1 from escaping.

[0036] Additionally, the position of the connecting rod 29 can be adjusted via the limiting bolt 27, thereby adjusting the compression of the return spring 28. This allows the return spring 28 to be used for rehabilitation exercises for different patients. By adjusting the distance between the guide plate 23 and the connecting rod 29 in the initial position, when the distance between the guide plate 23 and the connecting rod 29 is large, the return spring 28 is in an uncompressed state. At this time, a gentle breath will move the sealing cone 24 and open the vent. When the distance between the guide plate 23 and the connecting rod 29 is small, the return spring 28 will be in a compressed state, requiring a large breath to move the sealing cone 24. This is suitable for patients who need stronger exercises.

[0037] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
