Description

Technical Field

[0001] The invention belongs to the field of medical nursing rehabilitation training equipment, and in particular relates to a lung exhalation training device for nursing thoracic surgery patients. Background Art

[0002] Respiratory training for thoracic surgery patients is a type of rehabilitation training for patients who have undergone thoracic surgery or other respiratory diseases. It aims to help patients improve their respiratory function, increase their lung capacity and respiratory muscle strength, and promote recovery and restoration of health. After thoracic surgery, the patient's breathing ability will be more or less affected, and their lungs need to undergo respiratory exercise rehabilitation. When a person inhales normally, the diaphragm and the external intercostal muscles contract. When inhaling forcefully, the assistance of auxiliary inhalation muscles, such as the trapezius and scalene muscles, is also required. The result of these muscle contractions is that the chest is lifted up and the chest cavity space is expanded to the limit. During normal exhalation, there is no muscle contraction. When the diaphragm and external intercostal muscles relax, the chest cavity becomes smaller, the pressure in the lungs increases, and the air is exhaled from the body.

[0003] However, when the external air flow is obstructed, or for some patients who have suffered from or have chronic lung diseases, exhalation is not a completely relaxing process, but requires the participation of the expiratory muscles. When exhaling forcefully, the internal intercostal muscles contract to move the ribs downward, and the abdominal muscles contract to move the ribs downward to compress the abdominal viscera, forcing the diaphragm to bulge upward, thereby shrinking the volume of the chest cavity to a minimum and increasing the intrapulmonary pressure to a maximum, so that a large amount of carbon dioxide in the body can be exhaled.

[0004] According to the above principle, exhalation training can be performed on thoracic surgery patients, but there is no training equipment mainly based on exhalation in the existing equipment, and most respiratory trainers do not have the function of adjusting according to the specific conditions of the patients, and cannot meet the needs of the patients. Summary of the invention

[0005] In order to solve the above problems, the present invention designs a lung exhalation trainer for the care of thoracic surgery patients, which uses the elasticity of the corrugated airbag that undergoes deformation after inflation to add resistance to the gas exhaled by the patient when exhaling to achieve the training purpose. The patient's exhalation inflates the bellows and expands and deforms. The greater the deformation, the greater the resistance generated. By adjusting the corrugated airbag to deflate under the action of the U-shaped push rod, the resistance generated during the exhalation process is controlled by the patient. By adjusting the corrugated airbag to release gas at different degrees of deformation, the exhaled gas is subjected to different resistances. It can be adjusted at any time according to the needs of the patient, and the intensity can be adjusted according to the specific conditions of different patients to meet the training intensity required by different patients or different nursing stages.

[0006] In order to achieve the above technical objectives, the present invention is implemented by the following technical solutions: a lung exhalation trainer for nursing thoracic surgery patients, comprising an outer shell cover;

[0007] The outer shell is a rectangular parallelepiped, the interior is connected front to back and a corrugated airbag is installed inside, the front end of the corrugated airbag is provided with an air inlet, the front end of the air inlet is sleeved with a breathing mask, the rear end of the corrugated airbag is provided with an air outlet, a plurality of fixing pins are installed inside the air outlet, a rubber pad is installed on the plurality of fixing pins, a spring is installed on the fixing pin, and the action of the spring makes the rubber pad fit the air outlet;

[0008] A left-hand grip and a right-hand grip are respectively installed on the left and right sides of the outer shell cover, a cylindrical slide groove is provided on the right-hand grip, a fixing frame is installed at the rear end of the outer shell cover, the fixing frame is cross-shaped and has a positioning hole in the middle, a U-shaped push rod is installed in the positioning hole, a pushing end of the U-shaped push rod is connected to the rubber pad corresponding to the U-shaped push rod, and the other end of the U-shaped push rod is installed in the cylindrical slide groove and a control key is installed at the end.

[0009] Preferably, a rubber ring is installed at the edge of the breathing mask, and the rubber ring can increase the airtightness of the breathing mask when the breathing mask contacts the patient's face, so as to facilitate the exhalation training;

[0010] Preferably, the corrugated airbag will undergo elastic deformation after being inflated, and the maximum deformation length of the corrugated airbag after being filled with gas is greater than the length of the outer shell, so that the bellows can maintain its own elasticity after multiple deformations, thereby extending its service life;

[0011] Preferably, the rubber pad protrudes outwards corresponding to the air outlet of the corrugated airbag, and the protruding portion of the rubber pad can block the air outlet, thereby preventing the gas in the corrugated airbag from passing through the air outlet;

[0012] Preferably, the U-shaped push rod can slide in the cylindrical slide groove and the positioning hole, and the push end can prevent the U-shaped push rod from slipping when it slides to the rear end;

[0013] Preferably, an airway is connected between the breathing mask and the air inlet, and the airway is soft and deformable, so that it can be convenient for patients in different conditions to use;

[0014] Preferably, two upper and lower elastic fixing straps are installed on the breathing mask, and the elastic fixing straps can fix the breathing mask on the patient's face, making it convenient for the patient to wear it during training.

[0015] Beneficial effects of the present invention:

[0016] The present invention is applied to exhalation training of thoracic surgery patients, and the intensity of the breathing training can be adjusted according to the needs of the patients during training. During use, the patients can control the position of the U-shaped push rod with their right hand, thereby controlling the degree of deformation of the corrugated airbag in the outer shell cover. The resistance encountered by the exhalation is proportional to the degree of deformation, so that the resistance generated during the exhalation process is controlled by the patients, and the training intensity required by different patients or different nursing stages can be met.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. In addition, the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other.

[0028] Example 1

[0029] See also Figures 1 to 6 As shown, a lung exhalation trainer for nursing thoracic surgery patients is proposed, comprising a housing cover 2;

[0030] like Figure 1 As shown, the outer shell 2 is rectangular on the outside and cylindrical on the inside. Figure 3 As shown, a corrugated airbag 5 is installed inside the outer shell 2, and an air inlet 501 is opened at the front end of the corrugated airbag 5. Figure 6 The breathing mask 1 shown in the figure has one-way valves 101 installed on both sides of the breathing mask 1. The one-way valves 101 can realize one-way gas entering the breathing mask 1 during training, and a rubber ring 102 is installed on the edge of the breathing mask 1. When the breathing mask 1 contacts the patient's face, the rubber ring 102 can increase the airtightness of the breathing mask 1, which is convenient for exhalation training. The rear end of the corrugated airbag 5 is provided with an air outlet 502, and four fixing pins 601 are installed inside the air outlet 502. Figure 5 As shown, a rubber pad 6 is installed on the fixing pin 601, and a spring 602 is installed on each fixing pin 601. The force of the spring 602 makes the rubber pad 6 fit the air outlet 502. The rubber pad 6 protrudes outward corresponding to the air outlet 502 of the corrugated airbag 5, and the protruding part of the rubber pad 6 can block the air outlet 502, which can prevent the gas in the corrugated airbag 5 from passing through the air outlet 502. When the exhaled gas enters the corrugated airbag 5, the gas is blocked from passing through under the action of the rubber pad 6, so that the bellows expands. At this time, the patient's exhalation will be subject to resistance, and the resistance will increase with the expansion of the corrugated airbag 5.

[0031] A left-hand grip 4 and a right-hand grip 3 are respectively installed on the left and right sides of the outer shell cover 2. A cylindrical slide groove 301 is provided on the right-hand grip 3. A fixing frame 7 is installed at the rear end of the outer shell cover 2. The fixing frame 7 is cross-shaped and a positioning hole 701 is provided in the middle of the fixing frame 7. A U-shaped push rod 8 is installed in the positioning hole 701. A pushing end 802 is installed at the U-shaped push rod 8 corresponding to the rubber pad 6. The other end of the U-shaped push rod 8 is installed in the cylindrical slide groove 301 and a control key 801 is installed at the end. The control key 801 can drive the U-shaped push rod 8 to slide in the cylindrical slide groove 301 and the positioning hole 701, and the pushing end 802 can prevent the U-shaped push rod 8 from slipping when it slides to the rear end. When the corrugated airbag 5 is inflated, it will move toward The pushing end 802 moves, and finally the rubber pad 6 contacts the pushing end 802. When the corrugated airbag 5 continues to expand, the rubber pad 6 is separated from the air outlet 502 after being subjected to the resistance of the pushing end 802. At this time, the gas in the corrugated airbag 5 is released from the air outlet 502, and exhalation can be completed normally. When the gas in the corrugated airbag 5 is reduced, the corrugated airbag 5 contracts, and the rubber pad 6 blocks the air outlet 502 again. This cycle makes the resistance during exhalation constant. If it is necessary to increase the resistance during exhalation, just push the control key 801 in the direction of the fixing frame 7 to drive the pushing end 802 to move, so that the corrugated airbag 5 expands more, thereby increasing the resistance during exhalation; otherwise, the resistance during exhalation is reduced.

[0032] When using the device for breathing training, the thoracic surgery patient needs to hold the left hand grip 4 and the right hand grip 3 with both hands respectively, then pick up the device, align the breathing mask 1 with the mouth and close it to the patient's face to perform exhalation training. At this time, the patient can hold the control key 801 to fix the U-shaped push rod 8 while holding the right hand grip 3. By adjusting the control key 801, the resistance encountered during exhalation can be adjusted, and the resistance can be adjusted to a suitable size according to one's own needs.

[0033] Example 2

[0034] See also Figure 7 The lung exhalation trainer for thoracic surgery patient care shown is different from Example 1 in that an airway tube 9 is connected between the respiratory mask 1 and the air inlet 501, and the airway tube 9 is soft and deformable. Two upper and lower elastic fixing belts 10 are installed on the respiratory mask 1. The elastic fixing belts 10 can fix the respiratory mask 1 on the patient's face, which is convenient for the patient to wear and use during training. When using, there is no need to lift the device, and exhalation training can be performed by simply adjusting the position of the control key 801 by hand, which provides convenience for patients in special circumstances.

The preferred embodiments do not describe all details in detail, nor do they limit the invention to only the specific embodiments described. Obviously, many modifications and changes can be made according to the content of this specification.
