Description

Technical Field

[0001] This disclosure pertains to the field of pulmonary function training, specifically relating to a pulmonary function training device. Background Technology

[0002] After treatment, patients with lung diseases need to train their lung function. There are many ways to exercise lung function, among which blowing up balloons is more suitable for the initial stage of lung function training and for patients who have difficulty moving. The principle of existing lung function training is similar to blowing up balloons, which allows patients to exercise their lung function by repeatedly inhaling and exhaling.

[0003] For example, a respiratory pulmonary function training device for the elderly, with publication number CN222534039U, uses multiple sets of springs to support a moving plate. The position of the support plate can be adjusted by a threaded shaft, and the compression of the springs can be adjusted to control the support strength of the support plate, thereby adjusting the resistance of the blowing. It can be used by patients of different ages or with different disease degrees. However, adjusting the spring length by rotating the threaded rod is not convenient for the elderly and people with upper limb motor dysfunction (such as patients with arthritis or Parkinson's disease). Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide a lung function training device that solves the problems of the inability of people with difficulty in manual adjustment (such as elderly patients and those with upper limb dysfunction) to independently adjust the training resistance intensity, as well as the mismatch between training intensity and the patient's real-time lung function caused by the complexity of operation and high maintenance dependence of electronic devices.

[0005] The objective of this disclosure can be achieved through the following technical solutions:

[0006] A lung function training device, comprising: a cylinder, a lifting plate, and a self-locking assembly;

[0007] A hollow plate is slidably provided on the inner side of the straight cylinder, and a lifting plate is slidably provided directly above the hollow plate. A guide groove is provided through the side wall of the straight cylinder. Support plates are fixed on both sides of the lifting plate, and the support plates are provided through the guide groove. The moving path of the lifting plate is the same as the path of the guide groove.

[0008] The lifting plate is equipped with self-locking components at the guide slots on both sides to keep the lifting plate at the highest displacement point.

[0009] In some disclosures, a guide rod is fixed to the inner side of the straight cylinder, and the guide rod passes through the lifting plate and the hollow plate.

[0010] In some disclosures, a protective cover is provided around the outside of the straight cylinder, and both the straight cylinder and the protective cover are made of transparent material.

[0011] In some disclosures, exhaust holes are provided through the inner side of the hollow plate and the inner side of the lifting plate, and the exhaust holes on the lifting plate and the exhaust holes at the top of the straight cylinder are coaxially arranged.

[0012] In some disclosures, the self-locking assembly includes multiple protrusions fixed to both sides of a support plate, and limit pins are slidably provided on both sides of the support plate. The upper surfaces of the multiple protrusions are inclined downwards, and the lower surfaces of the protrusions are provided with grooves that are adapted to the limit pins.

[0013] In some disclosures, a limit cover is provided on the outer side of the self-locking assembly, and a limit groove is provided through the inner side of the limit cover, and the movement path of the limit pin is the same as the path of the limit groove.

[0014] In some disclosures, the self-locking assembly includes triangular protrusions fixed to both sides of the support plate, and a pawl is rotatably connected to the outer side of the straight cylinder, with the pawl being adapted to the position of the triangular protrusions, and a support spring fixed to the upper end of the pawl.

[0015] In some disclosures, the lower end face of the straight cylinder is connected to an air tube, which is installed through the bottom end of the straight cylinder, and the other end of the air tube is connected to a flexible tube.

[0016] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0017] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;

[0018] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0019] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0020] A sliding connection is a connection between parts that allows the parts to slide against each other.

[0021] The beneficial effects of this disclosure are:

[0022] Through the coordinated design of the counterweight lifting plate, the hollow plate that can move freely up and down, and the self-locking components, the function of automatically and passively adjusting the training resistance intensity according to the changes in the patient's expiratory force is effectively realized. This passive resistance adjustment mechanism based on expiratory force does not require any additional manual operation by the user, and can ensure that the training resistance matches the patient's current actual lung function in real time. It does not require electronic sensors and algorithm control, which significantly improves the convenience and safety of operation for elderly patients.

[0023] When the user exhales, the lifting plate is pushed upwards, and the lifting plate is locked in the highest position by the self-locking component. This locked position directly corresponds to the resistance value that the lungs can overcome when the user exhales with maximum force, realizing an objective and accurate quantitative record of lung function intensity and providing key data points for the rehabilitation process.

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0033] Please refer to Figures 1 to 6A lung function training device, comprising: a straight cylinder 1, a lifting plate 6, and a self-locking assembly;

[0034] A hollow plate 4 is slidably provided on the inner side of the straight cylinder 1, and a lifting plate 6 is slidably provided directly above the hollow plate 4. A guide groove 101 is provided through the side wall of the straight cylinder 1. Support plates 61 are fixed on both sides of the lifting plate 6, and the support plates 61 are provided through the guide groove 101. The moving path of the lifting plate 6 is the same as the path of the guide groove 101.

[0035] Self-locking components are provided at the guide grooves 101 on both sides of the lifting plate 6 to keep the lifting plate 6 at the highest displacement point.

[0036] During the exhalation test, the user exhales as quickly and forcefully as possible until they can exhale no more. The exhaled air moves vertically upwards within the cylinder 1. Initially, the lifting plate 6 is located at the lowest point of the guide groove 101. The user's exhaled air pushes the hollow plate 4 upwards until the upper surface of the hollow plate 4 is in contact with the lower surface of the lifting plate 6. If the pushing force of the user's exhaled air is less than the weight of the lifting plate 6, the hollow plate 4 will fall back downwards due to gravity when the user can no longer exhale. This completes one set of lung function exercises. Repeating the above operation performs expiratory resistance training to improve the user's lung function. As the user's lung function increases... After the hollow plate 4 is in contact with the lower end of the lifting plate 6, if the force of the user's exhaled air is greater than the weight of the lifting plate 6, the hollow plate 4 will drive the lifting plate 6 to move upward along the guide groove 101. When the user can no longer exhale, the air plate will fall downward, and the lifting plate 6 will be restricted to its highest point of movement by the self-locking component. This records the user's lung function intensity when exhaling at the fastest speed and with the greatest force. By pre-recording the range of the locked position of the lifting plate 6 after a group of healthy people (standard subjects) perform the same explosive exhalation, this range is marked as the "normal lung function zone". During daily exercise, users (such as patients in the recovery period) can observe the position reached by the lifting plate 6 after exhalation in real time and compare it with the clearly marked "normal lung function zone" position. This device allows users to directly, clearly, and visually assess the gap and closeness of their lung function recovery relative to the healthy standard without professional equipment or personnel assistance, greatly enhancing the self-monitoring efficiency and sense of purpose of rehabilitation training.

[0037] Please refer to Figures 1 to 4 A guide rod 3 is fixed inside the straight cylinder 1, and the guide rod 3 passes through the lifting plate 6 and the hollow plate 4;

[0038] In use, both the hollow plate 4 and the lifting plate 6 slide along the guide rod 3. The guide rod 3 further limits the movement path of the hollow plate 4, so that the hollow plate 4 slides parallel to the lifting plate 6 during the upward process, which helps to further improve the stability of the movement of the lifting plate 6 and the hollow plate 4.

[0039] Please refer to Figures 1 to 2 A protective cover 2 is provided around the outside of the straight cylinder 1, and both the straight cylinder 1 and the protective cover 2 are made of transparent material.

[0040] The transparent material allows for a direct observation of the movement of the lifting plate 6 and the hollow plate 4, which improves the intuitiveness of the device. Furthermore, the protective cover 2 is located on the outside of the self-locking assembly to provide protection for it.

[0041] Please refer to Figures 1 to 4 The inner side of the hollow plate 4 and the inner side of the lifting plate 6 are respectively provided with exhaust holes 5, and the exhaust holes 5 on the lifting plate 6 and the exhaust holes 5 at the top of the straight cylinder 1 are coaxially arranged.

[0042] After the hollow plate 4 and the lifting plate 6 are aligned, in order to prevent the hollow plate 4 from blocking the exhaust hole 5 and causing a sudden increase in air pressure at the bottom of the hollow plate 4, which poses a risk of alveolar damage for postoperative patients or patients with fragile lung tissue, the alignment of the exhaust hole 5 on the hollow plate 4 and the lifting plate 6 ensures that the air in the straight cylinder 1 can still flow out smoothly when the hollow plate 4 and the lifting plate 6 are aligned. Therefore, it helps to reduce the sudden increase in air pressure in the straight cylinder 1, thereby reducing the risk of alveolar damage.

[0043] Please refer to Figures 3 to 5 The self-locking assembly includes multiple protrusions 7 fixed on both sides of the support plate 61, and limit pins 71 are slidably provided on both sides of the support plate 61. The upper end surface of the multiple protrusions 7 is an inclined surface facing downwards, and the lower end surface of the protrusions 7 is provided with a groove that matches the limit pin 71.

[0044] Please refer to Figures 2 to 4 The self-locking component is provided with a limit cover 72 on the outside, and a limit groove 721 is provided through the inner side of the limit cover 72, and the movement path of the limit pin 71 is the same as the path of the limit groove 721.

[0045] The movement path of the limiting pin 71 is restricted by the limiting groove 721, so that when the protrusion 7 moves upward, the limiting pin 71 makes way for the protrusion 7, so as to avoid the limiting pin 71 and the protrusion 7 from interfering with each other.

[0046] Please refer to Figure 2The end of the limiting groove 721 near the self-locking component is lower than the other end of the limiting groove 721. This allows the limiting pin 71 to quickly reset under the influence of gravity after the pushing force of the protrusion 7 on the limiting pin 71 is weakened due to the influence of gravity after the limiting pin 71 moves away from the support plate 61 along the limiting groove 721.

[0047] In the first embodiment of the self-locking assembly, when in use, the lifting plate 6 tends to move downwards due to gravity. The groove on the lower end face of the protrusion 7 fits against the outer wall of the limiting pin 71, and the limiting pin 71 provides upward support to the lifting plate 6, thereby preventing the lifting plate 6 from moving downwards. When the hollow plate 4 drives the lifting plate 6 to move upwards, the limiting pin 71 is pushed by the upper inclined surface of the protrusion 7 to move along the limiting groove 721 to the end away from the support plate 61 until the protrusion below the original limiting pin 71 is completely moved to the upper end of the limiting pin 71. At this time, if the user finishes exhaling, the lifting plate 6 slides downwards due to gravity. At this time, the limiting pin 71 returns to its initial position and is locked below the protrusion 7 below the original limiting pin 71, thereby causing the position of the lifting plate 6 relative to the limiting pin 71 to move upwards.

[0048] Please refer to Figure 6 The self-locking assembly includes triangular protrusions 8 fixed on both sides of the support plate 61, and a pawl 81 is rotatably connected to the outer side of the straight cylinder 1. The pawl 81 is matched with the position of the triangular protrusions 8, and a support spring 82 is fixed at the upper end of the pawl 81.

[0049] In the second embodiment of the self-locking assembly, the upper end of the support spring 82 is fixed to the side wall of the straight cylinder 1, and the lower end of the support spring 82 is fixed to the middle of the upper end of the pawl 81 to keep the end of the pawl 81 horizontal. At the same time, the upper surface of the end of the pawl 81 is in contact with the lower end surface of its corresponding triangular protrusion 8. The support spring 82, pawl 81 and triangular protrusion 8 apply an upward supporting force to the support plate 61 and the lifting rod to achieve the downward displacement of the lifting plate 6 under the action of gravity. During the upward movement of the lifting plate 6, the inclined surface of the triangular protrusion 8 contacts the lower end surface of the pawl 81 and pushes the pawl 81 to rotate upward to avoid the triangular protrusion 8. At the same time, after exhalation, the support plate 61 moves downward under the action of gravity and is locked by the pawl 81, thereby achieving the effect that the lifting plate 6 can move upward and is automatically locked when moving downward. This allows the maximum upward displacement of the lifting plate 6 and the current lung function intensity of the user to be recorded.

[0050] Please refer to Figures 1 to 4 The lower end of the straight cylinder 1 is connected to an air pipe 9, which is installed through the bottom of the straight cylinder 1, and the other end of the air pipe 9 is connected to a flexible hose 10.

[0051] When in use, the patient delivers gas into the straight tube 1 through the hose 10 and the trachea 9, causing the hollow plate 4 to move upward.

[0052] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the lung function training device provided by this utility model.

[0053] When the user exhales through the hose 10 and trachea 9 into the bottom of the cylinder 1, the airflow pushes the hollow plate 4 vertically upward along the guide rod 3 fixed inside the cylinder 1. Initially, the lifting plate 6 is embedded in the lowest point of the guide groove 101 of the cylinder 1 via the two side support plates 61. After the upper surface of the hollow plate 4 contacts the lower surface of the lifting plate 6:

[0054] If the exhalation thrust is less than the weight of the lifting plate 6, the hollow plate 4 will fall back to its original position along the guide rod 3 when the exhalation ends, and the lifting plate 6 will remain in its original position.

[0055] If the exhalation thrust continues to increase until it overcomes the weight of the lifting plate 6, the hollow plate 4 pushes the lifting plate 6 upward along the guide groove 101. At this time:

[0056] The inclined surfaces of the protrusions 7 on both sides of the support plate 61 push the limiting pin 71 to move outward along the inclined limiting groove 721 of the limiting cover 72 to avoid it; when the exhalation ends, the lifting plate 6 moves downward under the force of gravity, and the limiting pin 71 slides into the groove of the adjacent lower protrusion 7 under the action of gravity to lock the height.
