Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a respiratory training device for respiratory medicine. Background Technology

[0002] The Department of Respiratory Medicine primarily diagnoses and treats various diseases of the respiratory system, including acute upper respiratory tract infections, bronchitis, chronic obstructive pulmonary emphysema, chronic pulmonary heart disease, bronchiectasis, bronchial asthma, pneumonia, lung abscess, tuberculosis, lung cancer, and pulmonary embolism, as well as respiratory failure. Lung diseases are the main focus of treatment, and post-treatment lung rehabilitation is particularly important.

[0003] Based on the above, current pulmonary function rehabilitation training mainly involves patients performing regular inhalation and exhalation. For example, a pulmonary function rehabilitation training device for respiratory patients disclosed in Chinese utility model patent (publication number: CN220938996U) uses a spring to apply a reaction force to the mounting plate, thereby providing expiratory resistance for the patient and forming a rehabilitation training for the patient's lungs.

[0004] However, the aforementioned device can only train the exhalation process, meaning it only trains the expiratory muscles and not the inspiratory muscles, thus limiting its use. Utility Model Content

[0005] The purpose of this invention is to provide a respiratory training device for respiratory medicine, which solves the problem that existing training devices only have the function of training expiratory muscles and not inspiratory muscles, thus limiting their use.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A respiratory training device for respiratory medicine, comprising:

[0008] The supervisor, one end of which is equipped with a breathing mask;

[0009] A secondary pipe, with a connector at each end, is connected to the interior of the main pipe via the two connectors;

[0010] A movable plug, which is inserted into the main pipe;

[0011] The side wall of the main tube is also fixedly provided with an air outlet, which is connected to the interior of the main tube and located between the two connectors;

[0012] The side wall of the main tube is also provided with an installation hole, in which a positioning pin is movably inserted. A stop block is detachably installed on the outer wall of the main tube, and a compression spring is installed between the stop block and the positioning pin.

[0013] The side wall of the movable plug is provided with a positioning groove, the depth of which gradually increases from both ends to the middle, and the free end of the positioning pin is located in the positioning groove.

[0014] The main tube includes a main tube and a sleeve, with one end of the sleeve connected to the main tube and the other end connected to the breathing mask;

[0015] The two connectors are the first elbow and the second elbow, respectively;

[0016] The first elbow is integrally formed with the main pipe, and one end of the secondary pipe is inserted into the first elbow;

[0017] The second elbow is located between the secondary pipe and the sleeve, and is integrally formed with the secondary pipe and the sleeve;

[0018] The movable plug is inserted inside the main tube.

[0019] This structural design, by dividing the main pipe into a main pipe and a sleeve, and using the first elbow and the second elbow as two connecting heads, has a simple structure, is easy to manufacture, is easy to demold, and has strong practicality.

[0020] Furthermore, the outer wall of the main tube is fixedly provided with a mounting cylinder at the mounting hole, and the positioning pin passes through the mounting cylinder. This structural design, by loading the positioning pin with the mounting cylinder, increases the contact area between the positioning pin and the main tube, extends the service life of the main tube, and at the same time, the mounting cylinder can also provide an installation position for the stop block, making it highly practical.

[0021] Furthermore, the stop block is screwed into the mounting cylinder. This structural design, through the screw connection between the stop block and the mounting cylinder, not only achieves a detachable connection between the stop block and the main tube, but also allows for adjustment of the distance between the lower end face of the stop block and the upper end face of the positioning pin by rotating the stop block. This adjusts the prestress of the compression spring acting on the positioning pin, thereby regulating the resistance during inhalation / exhalation training, making it highly practical.

[0022] Furthermore, the side wall of the stop block is axially provided with an indicator groove, and a scale line is provided within the indicator groove. An arrow is provided on the outer wall of the mounting cylinder. This structural design, through the interaction of the scale line and the arrow, indicates the prestress exerted by the stop block on the positioning pin, achieving the effect of gear adjustment indication and making it more convenient to use.

[0023] Furthermore, the lower end face of the stop block and / or the upper end face of the positioning pin are provided with blind holes, and the compression spring passes through the blind holes. This structural design, by accommodating the compression spring through the blind holes, reduces the overall length requirements of the stop block and the positioning pin, making it highly practical.

[0024] Further specifying, an operating lever is fixedly installed at the end of the movable plug away from the breathing mask.

[0025] This structural design allows for easy operation of the movable plug during installation via an operating lever, facilitating the alignment of the positioning groove and positioning pin on the movable plug, making disassembly and assembly more convenient and highly practical.

[0026] The utility model adopting the above technical solution has the following advantages:

[0027] 1. Through the cooperation of the movable plug, compression spring, positioning pin and the inclined surface of the positioning groove, the blockage of the first bend and the air outlet is released during inhalation and exhalation respectively, so that the corresponding airflow channels are formed in the training device, thereby smoothly completing the training process. It provides resistance for both inhalation and exhalation, thereby achieving the training effect on the expiratory and inspiratory muscles at the same time. At the same time, it allows the movable plug to be reset smoothly, which is convenient for secondary training.

[0028] 2. By screwing the stop block to the mounting cylinder, a detachable connection between the stop block and the main tube is achieved. The distance between the lower end face of the stop block and the upper end face of the positioning pin can be changed by rotating the stop block, thereby adjusting the prestress of the compression spring acting on the positioning pin to adjust the resistance during inhalation / exhalation training. This method is highly practical. Attached Figure Description

[0043] like Figures 1-6 As shown, this utility model discloses a respiratory training device for respiratory medicine, comprising:

[0044] The supervisor is equipped with a breathing mask 10 at one end;

[0045] Secondary pipe 2, with a connector at each end, is connected to the interior of the main pipe via the two connectors;

[0046] Movable plug 4, which is installed inside the main pipe;

[0047] The side wall of the main pipe is also fixedly provided with an air outlet 12, which is connected to the interior of the main pipe and located between the two connectors;

[0048] The side wall of the main pipe is also provided with an installation hole, in which a positioning pin 5 is movably inserted. A stop 51 is detachably installed on the outer wall of the main pipe, and a compression spring 52 is installed between the stop 51 and the positioning pin 5.

[0049] The side wall of the movable plug 4 is provided with a positioning groove 40. The depth of the positioning groove 40 gradually increases from both ends to the middle. The free end of the positioning pin 5 is located in the positioning groove 40.

[0050] The main tube includes a main tube 1 and a sleeve 3. One end of the sleeve 3 is connected to the main tube 1, and the other end is connected to the breathing mask 10.

[0051] The two connectors are the first elbow 11 and the second elbow 21, respectively;

[0052] The first elbow 11 is integrally formed with the main pipe 1, and one end of the secondary pipe 2 is inserted into the first elbow 11.

[0053] The second elbow 21 is located between the secondary pipe 2 and the sleeve 3, and is integrally formed with the secondary pipe 2 and the sleeve 3;

[0054] The movable plug 4 is inserted inside the main tube 1.

[0055] In practice, depending on the actual situation, the main pipe can be cast as a single piece. In this embodiment, the main pipe is divided into a main pipe 1 and a sleeve 3, and the first elbow 11 and the second elbow 21 are used as two connecting heads. The structure is simple, easy to manufacture, easy to demold, and highly practical.

[0056] An installation cylinder 510 is fixedly installed on the outer wall of the main tube at the installation hole, and the positioning pin 5 passes through the installation cylinder 510. The positioning pin 5 is loaded by the installation cylinder 510, which increases the contact area between the positioning pin 5 and the main tube 1 and extends the service life of the main tube 1. At the same time, the installation cylinder 510 can also provide an installation position for the stop block 51, which is highly practical.

[0057] The stop block 51 is screwed into the mounting cylinder 510. In practice, depending on the actual situation, a snap-fit ​​structure can also be directly set on the stop block 51 to complete the connection between the stop block 51 and the main tube 1. In this embodiment, by screwing the stop block 51 into the mounting cylinder 510, a detachable connection between the stop block 51 and the main tube 1 is achieved. Furthermore, by rotating the stop block 51, the distance between the lower end face of the stop block 51 and the upper end face of the positioning pin 5 can be changed, thereby adjusting the prestress of the compression spring 52 acting on the positioning pin 5, so as to adjust the resistance during inhalation / exhalation training. This method is highly practical.

[0058] The side wall of the stop block 51 is provided with an axially oriented indicator groove 520, and a scale line 521 is provided in the indicator groove 520. An arrow 522 is provided on the outer wall of the mounting cylinder 510. Through the cooperation of the scale line 521 and the arrow 522, the prestress of the stop block 51 acting on the positioning pin 5 is indicated, so as to achieve the effect of gear adjustment indication and make it more convenient to use.

[0059] A blind hole is provided on the lower end face of the stop block 51 and / or the upper end face of the positioning pin 5, and the compression spring 52 passes through the blind hole. By accommodating the compression spring 52 through the blind hole, the overall length requirement of the stop block 51 and the positioning pin 5 can be reduced, which is more practical.

[0060] An operating lever 41 is fixedly installed at the end of the movable plug 4 away from the breathing mask 10.

[0061] The movable plug 4 is operated by the operating lever 41 during installation, which facilitates the alignment of the positioning groove 40 and the positioning pin 5 on the movable plug 4, making disassembly and assembly more convenient and practical.

[0062] In this embodiment, during installation, the operating lever 41 is grasped and the movable plug 4 is inserted into the main body tube 1 so that the positioning groove 40 is aligned with the mounting hole of the main body tube 1.

[0063] Then, the positioning pin 5 and the compression spring 52 are placed into the mounting cylinder 510 in sequence, and the stop block 51 is screwed onto the mounting cylinder 510.

[0064] Next, align the sleeve 3 with the main tube 1, align the secondary tube 2 with the free end of the first bend 11, and squeeze laterally to complete the installation between the main tube 1 and the secondary tube 2. Finally, install the breathing mask 10 on the sleeve 3.

[0065] When using it, select the appropriate gear according to the patient's condition by rotating the stop 51 to adjust the gear.

[0066] After adjustment, the positioning pin 5 moves downward under the action of the compression spring 52. Through the cooperation of the two inclined surfaces of the positioning pin 5 and the positioning groove 40, the lower end of the positioning pin 5 abuts against the lowest point in the middle of the positioning groove 40. At this time, the moving plug 4 blocks both the first bend 11 and the air outlet 12 (e.g., Figure 1 and Figure 3 (as shown)

[0067] When using a breathing trainer for inhalation training, the breathing mask 10 is placed over the patient's mouth, and then inhalation is performed. This creates negative pressure on the right side of the movable plug 4, overcoming the prestress of the compression spring 52 and causing the movable plug 4 to move to the right. This disengages the movable plug 4 from the first bend 11, allowing outside air to enter the breathing mask 10 from the free end of the main tube 1, sequentially through the first bend 11, the secondary tube 2, and the second bend 21 (e.g., ...). Figure 5 (as shown)

[0068] When using a breathing trainer for expiratory training, the breathing mask 10 is placed over the patient's mouth, and then air is blown in. This creates positive pressure on the right side of the movable plug 4, overcoming the prestress of the compression spring 52 and causing the movable plug 4 to move to the left. This disengages the movable plug 4 from the outlet 12, allowing the air inside the breathing mask 10 to be expelled from the outlet 12 through the sleeve 3 and the main tube 1 (e.g., Figure 6 (as shown)

[0069] When inhalation / exhalation stops, the lower end of the positioning pin 5 rests against the inclined surface of the positioning groove 40. When training stops, the negative / positive pressure no longer exists and no longer applies lateral pressure to the moving plug 4. At this time, the positioning pin 5, squeezed by the compression spring 52, tends to move downward. The cooperation between the positioning pin 5 and the inclined surface of the positioning groove 40 drives the moving plug 4 to reset.

[0070] The above provides a detailed description of a respiratory training device for respiratory medicine provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
