Description

A pulmonary breathing training device for thoracic surgery recovery

technical field

The invention relates to the technical field of medical lung training devices, in particular to a lung breathing training device for thoracic surgery recovery.

Background technique

Breathing training is an important measure to prevent lung infection and care for lung diseases. The purpose of breathing training is to make shallow and fast breathing. When a person inhales normally, the diaphragm contracts and the external intercostal muscles contract. When inhaling forcefully, the assistance of inspiratory auxiliary muscles, such as trapezius and scalene muscles, is also required. As a result of the contraction of these muscles, the chest width is raised and the thoracic space is expanded to the limit. Therefore, the inspiratory muscles need to be exercised. Most breathing trainers use the basic principle of resistance training. When inhaling through the inspiratory trainer, the user needs to exert effort to resist the resistance set by the training device to increase the strength of the inspiratory muscle, thereby increasing the strength and tolerance of the breathing muscle. Through training, it can be transformed into deep and slow effective breathing. Through breathing training, it can improve the tolerance of surgery, restore the respiratory function of the lungs, prevent postoperative complications of the lungs, and enhance the patient's self-confidence.

The existing training devices generally use resistance devices to increase the difficulty of breathing for training. Patients will hold the respirator in their mouths to breathe to achieve the purpose of training. However, due to the poor self-consciousness of most patients, they cannot. Focus on breathing training, especially for children. When training, you cannot focus on training, but the training process needs to keep the process of each breathing training deep and slow to ensure The effect of training, but if you are not focused, it will lead to disordered breathing, so the training effect is not good. In addition, the existing training device cannot allow the patient and the medical staff to make a good judgment on each breath. To what extent, I only know how to use the training device to perform exhalation and inhalation training when training, but I don’t know how to exert force and how much force is correct, so when training, I think that you only need to use your mouth to face it. The respirator is enough to breathe, and it does not pay attention to the strength and frequency of breathing, so it often fails to focus on breathing training, resulting in poor training results.

Based on this, the present invention designs a pulmonary breathing training device for thoracic surgery recovery to solve the above problems.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 9 , the present invention provides a technical solution: a pulmonary breathing training device for thoracic surgery recovery, comprising a main body 01, an air intake nozzle 02 is arranged on the main body 01, and the inner wall of the air intake nozzle 02 is fixedly connected There is a fixed block 10, a rotating shaft 33 is rotatably connected to the fixed block 1 10, and a gas impeller 11 located inside the body 01 is fixedly connected to the rotating shaft 33. The body 01 is also provided with a flow regulating device. The flow regulating device includes a fixed connection to the body. The inner wall of 01 is located at the fixed ring 31 at one end of the gas impeller 11 inside the body 01. The fixed ring 31 is fixedly connected to the throttle plate 24 for rotation, and the throttle plate 24 is fixedly connected with a gear one 27. The axis ring array of 31 is provided with multiple groups and multiple throttle plates 24 can form a closed circular plate, and the outermost periphery of the circular plate composed of multiple throttle plates 24 is sleeved with a gas limited rotation connected to the inner wall of the body 01. The second valve 25, the ring gear 26 mesh with the first gear 27, and the body 01 is also provided with an adjusting device that can adjust the ring gear 26 to rotate.

When using, the patient bites the end of the main body 01 away from the air intake nozzle 02 with his mouth so that the air intake nozzle 02 faces upwards. At this time, the patient can see the air impeller 11 in the main body 01 through the air intake nozzle 02. When breathing through the mouth, the nose is closed, and when exhaling, the air flow will pass through the patient's lungs and then to the mouth, and then blow out towards the direction of the air intake nozzle 02 through the end of the body 01 away from the air intake nozzle 02, and inhale the air. The opposite is true when breathing, the airflow flows into the body 01 through the air inlet 02, and is then inhaled into the patient's lungs through the body 01 to complete the entire breathing process; since the breathing process is carried out by biting the body 01 with the mouth, it is Abdominal breathing, abdominal breathing is to move the diaphragm up and down, because the diaphragm will drop when inhaling, squeezing the organs to the bottom, so the abdomen will expand, not the chest, therefore, the diaphragm will expand when exhaling. It will rise more than usual, so you can take a deep breath and spit out more carbon dioxide that is easy to stagnate at the bottom of the lungs, so the exercise effect is better; because the air impeller 11 is provided, when the airflow passes through the air impeller 11, no matter whether the air is in or out , can make the gas impeller 11 rotate on the fixed block 10 through the rotating shaft 33, and the rotation direction of the gas impeller 11 is opposite when the gas is in and out. The rotation of the gas impeller 11 can detect whether there is airflow And the doctor can observe whether the patient's breathing is smooth when training, and at the same time, the rotation speed of the air impeller 11 can judge whether the breathing force is correct during the training process. For example, the doctor can guide the patient to make it in a process of inhalation or exhalation. In order to keep the gas impeller 11 rotating continuously for a long time, the patient needs to keep an inhalation or breathing process for a long time, and the gas impeller 11 needs to be kept in the state of exerting force to rotate, and the air flow when exerting force The air impeller 11 can only rotate when the flow rate is fast, so it can exercise the function of exercising the lung muscles. Moreover, due to the existence of the physiological dead space, the nose, throat, trachea, bronchi and other places do not have the function of exchanging with gas, so when the gas enters In the alveoli, because the blood flow is unevenly distributed in the lungs, part of the gas cannot be exchanged with the blood, so the slow and long breathing process can exercise the gas exchange function of the lungs better than the short and rapid breathing; moreover, Since the air intake nozzle 02 faces the patient's face, the patient can observe the effect of the rotation of the gas impeller 11 during the training, so the training can be carried out independently, and the overall structure of the device is simple, and the whole body can be made of lightweight materials. The cost is low, and the patient can directly hold the body 01 through the mouth, which is very convenient to use. In addition, the rotation of the gas impeller 11 can improve the patient's attention, so that they can focus on the rotating effect of the gas impeller 11. Therefore, it needs to focus on controlling the lung muscles to blow the air flow, so that the exercise effect is better, especially for young patients, so it is also possible to apply patterns or install lights on the air impeller 11, so as to better attract the attention of the patient; in addition, due to the provision of the throttle plate 24, the rotation of the ring gear 26 is adjusted by the adjustment device , the ring gear 26 will drive the gear one 27 to drive the throttle plate 24 to rotate. For example, referring to Figure 5 and Figure 6, when the ring gear 26 rotates counterclockwise, it will drive the gear one 27 to drive the throttle plate 24 and counterclockwise. Rotation, so that all the throttle pieces 24 will gradually open, so that a circular hole will gradually be formed in the middle of the circular plate composed of all the throttle pieces 24, and with the rotation of the ring gear 26, the diameter of the circular hole will gradually If the diameter of the circular hole is increased, the diameter of the circular hole will be reduced by rotating clockwise. When the air flow is smaller, the patient's exhalation or inhalation time will become larger, so it can exercise the air exchange function of the lungs. Because the respiratory function of patients with lung disease before surgery is due to the presence of lesions, the Poor, there are wounds in the lungs after the operation, so the recovery period is also relatively poor. Therefore, the overall respiratory function is relatively fragile, so it is impossible to breathe hard. Therefore, before the operation and during the recovery exercise immediately after the operation, rotate the ring gear 26. The circular hole formed by the flow sheet 24 is adjusted to the maximum, so that the air impeller 11 can pass the maximum airflow, so that the patient can breathe more easily. With the postoperative recovery, the area of the circular hole of the flow sheet 24 can be gradually reduced, thereby reducing the airflow through In addition, after adjusting the size of the circular hole of the throttle plate 24, it is necessary to ensure that the air impeller 11 rotates during training, so as to ensure the training effect. ;

When performing breathing training, the airflow will circulate in the body 01, so that the gas impeller 11 can be rotated. Through the rotation of the gas impeller 11, it is convenient for medical staff and patients to observe the degree of exertion, and only need to exert force to keep the gas impeller 11. It is enough to rotate at a constant speed, and the patient needs to focus on controlling the rotation of the gas impeller 11 when training, but the rotation of the gas impeller 11 requires the patient to control the breathing and stabilize the gas impeller 11 to rotate at a constant speed, so the patient will The focus is on training, so it's easier to layer the training, so it works better, and the lungs get better training.

As a further solution of the present invention, a force indicating device is also provided on the rotating shaft 33, and the strength indicating device includes a buckle cover 13 fixedly connected to the rotating shaft 33, and a sliding rod 14 is connected in a limited position in the buckle cover 13, and the sliding rod 14 is away from the rotating shaft. One end of the 33 is fixedly connected with the identification plate 15 , and the outer wall of the sliding rod 14 is sleeved with a spring that can perform a reset movement toward the direction of the rotating shaft 33 .

Referring to FIG. 2 , when the gas impeller 11 rotates, the gas impeller 11 will drive the rotating shaft 33 to rotate, the rotating shaft 33 will drive the buckle cover 13 to rotate, and the buckle cover 13 will drive the sliding rod 14 so that the axis of the rotating shaft 33 is The center of the circle rotates in a circle, and when the rotational speed of the gas impeller 11 reaches the centrifugal force, the sliding rod 14 will overcome the force of the spring on the sliding rod 14 and move in the direction away from the rotating shaft 33, so that the sliding rod 14 will push the marking plate 15 to move out. Buckle cover 13, so that the patient can visually observe that the identification disc 15 protrudes from the buckle cover 13, so paint or light can be applied on the identification plate 15, so as to better attract the patient's attention;

Whether the rotation speed of the gas impeller 11 reaches the standard can be judged by whether the identification plate 15 extends out of the buckle cover 13. Therefore, when the patient performs training, the rotation speed of the gas impeller 11 needs to reach the standard through breathing, so as to facilitate the patient to observe the effect of the training by himself. Therefore, the training of each breathing can meet the training requirements, so that the training plan can be gradually carried out, so the training effect is better and the use is very convenient.

As a further solution of the present invention, the body 01 is also provided with a one-way breathing air training device, and the breathing air one-way training device includes a fixed piece 18 that is fixedly connected to the inner wall of the body 01 and located below the throttle piece 24, and the fixed piece 18 is far away from the throttle. A suction pipe 21 and a limit ring 17 are fixedly connected to one side of the sheet 24. The suction pipe 21 and the limit ring 17 pass through the fixed sheet 18. The inner wall of the body 01 is connected with a filter cotton 16 in a limited rotation, and the filter cotton 16 is tightly connected. Attached to the end of the suction pipe 21 away from the fixing sheet 18, the filter cotton 16 is provided with a main air hole 23 and a secondary air hole 22, and the interior of the main body 01 is also provided with an air valve 19 and an air valve 25, an air valve 19 and an air valve 2 25 is provided with a floating ball 20, the upper end of the air valve 19 is communicated with the outer wall of the main body 01, the lower end is communicated with the auxiliary air hole 22, the lower end of the air valve 25 is communicated with the outer wall of the body 01, and its upper end is communicated with the auxiliary air hole 22. , the main body 01 is also provided with a drive assembly that can adjust the rotation of the filter cotton 16 .

Due to the poor lung function of the patient before and after the operation, it is more difficult to directly perform a complete breathing training process during training, and it is easy to exert excessive force and cause injury. Therefore, the training needs to be divided into exhalation training. process and inhalation training process;

Referring to Figure 4, Figure 7 and Figure 8, in the state of Figure 8, when performing inhalation training, the filter cotton 16 needs to be rotated so that the main air hole 23 is communicated with the limit ring 17, and the auxiliary air hole 22 is communicated with the air valve one 19. , when the patient inhales, the airflow flows into the body 01 through the air intake nozzle 02, and then flows into the limiting ring 17, then flows into the body 01 through the main air hole 23, and then inhales into the lungs through the patient's mouth, During this process, under the action of gravity, the floating ball 20 will block the air valve one 19, and when the airflow flows into the intake valve one 19, it will squeeze the floating ball 20 to make the seal tighter, so that the air valve one 19 can not be communicated with the outside world, the filter cotton 16 will block the suction pipe 21 and the air valve 2 25, so that the two cannot be ventilated, the inhalation ends, and the exhalation begins. Because the air impeller 11 rotates, there will be inertia, so it will also rotate. For a period of time, even if the patient does not inhale, the air impeller 11 can draw the external air into the body 01. When the patient exhales, it will collide with the air flow sent by the air impeller 11, so the air flow is easier to flow to the air valve Inside one 19, the floating ball 20 is blown up, and the air flow will be blown out to the outside of the main body 01 through the air valve one 19, so that there is no resistance of the throttle plate 24 and the air impeller 11 during the exhalation process, so it is more smooth, and at the same time It is not easy to make the air impeller 11 start to reverse directly; when performing exhalation training, contrary to the inhalation training process, rotating the drive assembly makes the main air hole 23 of the filter cotton 16 rotate to the position of the inhalation pipe 21, and the auxiliary air hole 22 rotates to the air The position of valve 2 25, at this time, the filter cotton 16 will block the limit ring 17 and the suction pipe 21, and the airflow will flow in the direction of the gas impeller 11 through the suction pipe 21, thereby blowing the gas impeller 11 to rotate, and the airflow will The floating ball 20 in the second air valve 25 is pushed to move downward so that the air flow cannot flow out of the body 01 through the second air valve 25; therefore, the two training processes can be switched by rotating the filter cotton 16, thus ensuring the training effect and protecting the patient at the same time. .
