Description

Technical Field

[0001] This invention relates to the field of breathing training technology, specifically a modular breathing training device. Background Technology

[0002] After surgery for lung diseases, patients need rehabilitation training, especially those with lung or respiratory problems. Postoperative lung capacity and other factors directly affect their quality of life. Currently, patients often need to use respiratory trainers after surgery. They usually need to learn abdominal breathing, which involves the diaphragm moving up and down, causing the abdomen to expand rather than the chest. When exhaling, more carbon dioxide that tends to stagnate at the bottom of the lungs is expelled. Current respiratory training devices mainly use three floats that can be raised by air pressure for prompting. Due to their cost advantages, they are widely used in postoperative rehabilitation. However, current respiratory training devices are not convenient for modular assembly and use. Patients cannot easily understand the correctness of abdominal breathing in real time, nor can they practice abdominal breathing more intuitively. They also cannot prompt patients to stop exhaling in time. Excessive exhalation can easily cause over-fatigue and hypoxia. In addition, current respiratory trainers often require patients to invert the respiratory trainer when switching between exhalation and inhalation, which is not practical and does not facilitate the use of valve structure to integrate rapid switching between exhalation and inhalation.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention uses a one-way flow component and utilizes a one-way flow structure. With the intubation tube located between two one-way limiting rings, the two stop balls can automatically switch between exhalation and inhalation, eliminating the need for the patient to invert the breathing trainer. This reduces the difficulty of using this structure and prevents the problem of patients forgetting to switch to a traditional breathing trainer and being unable to exhale or inhale properly, thus failing to achieve the training effect. The two one-way flow components ensure that the patient can flexibly switch between exhalation and inhalation.

[0016] 2. This invention employs an anti-fatigue control unit, which can prevent patients from undergoing prolonged expiratory training. As exhalation becomes more frequent, patients may experience hypoxia or fatigue. This unit optimizes the intensity of patient training, avoids overtraining, and improves overall training safety. The anti-fatigue control unit can detect the patient's exhalation and obtain the expiratory pressure. Once the patient experiences a decrease in expiratory pressure due to fatigue or hypoxia, the patient can easily be notified and take timely rest and adjustment. Furthermore, the anti-fatigue control unit can adjust the calibration value according to different patient needs, making it more practical. The alarm indicator light provides a more intuitive prompt.

[0017] 3. This invention uses a pneumatic connector, which can be worn on the patient's abdomen in conjunction with the abdominal connector to detect the degree of abdominal movement during breathing training. This makes it easier for the patient to perform abdominal breathing and improves the effect of breathing training. The piston cylinder uses a magnetic connection method and modular assembly, which makes it more flexible to use and can improve the standardization of the patient's breathing training.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-11 As shown:

[0037] The aforementioned breathing conduction device 1 further includes: a limiting protrusion 103, a floating ball 104, a connecting tube 105, and an alarm indicator light 106. Six limiting protrusions 103 are fixedly installed on the inner bottom sides of the three pressure tubes 102 respectively; a floating ball 104 is sleeved inside the pressure tube 102; the floating ball 104 is located above the limiting protrusions 103; the connecting tube 105 is fixedly connected to the top of the three pressure tubes 102; graduation lines are respectively opened on the three pressure tubes 102; an alarm indicator light 106 is fixedly installed on the connecting tube 105; the alarm indicator light 106 is used to indicate that the air pressure is within the standard range; a magnet is provided on the side of the connecting tube 105; a through hole is provided at the top of the connecting tube 105.

[0038] The aforementioned training air delivery component 2 includes: a breathing tube 201, one-way limiting rings 202, a connecting tube 203, and a bellows 204. The breathing tube 201 is fixedly installed on the base plate 101; the top of the breathing tube 201 is fixedly installed on the connecting tube 105; the breathing tube 201 connects the base plate 101 and the connecting tube 105; two one-way limiting rings 202 are fixedly sleeved inside the breathing tube 201, and the inner sides of the two one-way limiting rings 202 are... The device features an inclined structure; two unidirectional limiting rings 202 are arranged in the same direction; a endotracheal tube 203 is fixedly installed on the breathing tube 201; the endotracheal tube 203 is located between the two unidirectional limiting rings 202; a corrugated tube 204 is sleeved on the endotracheal tube 203; a mouthpiece is provided on the corrugated tube 204; the corrugated tube 204 is used for inhalation and exhalation; a training air guide 2 is used, which can be used in conjunction with the breathing guide 1 to facilitate patients' real-time understanding of their breathing training effect, making the training more efficient.

[0039] The unidirectional flow component 3 includes: a limiting and fixing plate 301 and a sliding shaft 302. The limiting and fixing plate 301 is fixedly installed inside the breathing tube 201, and there are two limiting and fixing plates 301. The limiting and fixing plate 301 is provided with four through holes. The sliding shaft 302 is slidably installed on the limiting and fixing plate 301.

[0040] In the specific technical solution of this invention embodiment, the one-way flow component 3 further includes: a stop ball 303 and a tension spring 304. The stop ball 303 is fixedly installed on the slide shaft 302. The stop ball 303 has a rubber coating on its exterior. The stop ball 303 is attached to the inner side of the one-way limiting ring 202. The tension spring 304 is sleeved on the slide shaft 302. The tension spring 304 is connected between the slide shaft 302 and the limiting fixing plate 301. By using the one-way flow component 3, the one-way flow structure is utilized. With the insertion tube 203 located between the two one-way limiting rings 202, the two stop balls 303 can automatically switch between exhaling and inhaling, eliminating the need for the patient to invert the breathing trainer. This reduces the difficulty of using this structure and prevents the patient from forgetting to switch to the traditional breathing trainer, thus failing to achieve the training effect.

[0041] The above-mentioned technical solution utilizes a one-way flow element 3, which makes it more convenient for patients to use and makes breathing training smoother. When patients are performing breathing training, the through hole at the top of the connecting tube 105 and the through hole at the bottom of the base plate 101 respectively play the role of depressurization to ensure airflow. The two one-way flow elements 3 ensure that patients can switch flexibly between exhalation and inhalation, making it more practical.

[0042] The fatigue control unit 4 includes a control threaded rod 401 and a control handwheel 402. The control threaded rod 401 is threadedly connected to the base plate 101. The control handwheel 402 is fixedly installed at the bottom of the control threaded rod 401. The control threaded rod 401 is aligned with the bottom sliding shaft 302.

[0043] In a specific technical solution of this invention embodiment, the anti-fatigue control unit 4 further includes: a micro switch 403, which is fixedly embedded at the end of the control threaded rod 401; the end of the micro switch 403 is aligned with the bottom sliding shaft 302; the micro switch 403 is electrically connected to the alarm indicator light 106. Using the anti-fatigue control unit 4 can prevent patients from undergoing prolonged exhalation training. With frequent exhalation, patients are prone to hypoxia or fatigue. This structure can optimize the intensity of patient training and avoid overtraining. It also improves the overall safety of training. The anti-fatigue control unit 4 can detect the patient's exhalation and obtain the patient's exhalation pressure. Once the patient's exhalation pressure decreases due to fatigue or hypoxia, the patient can easily be notified and take timely rest and adjustment.

[0044] Meanwhile, the aforementioned anti-fatigue control unit 4 can adjust the calibration value according to different patient needs, making it more practical. Rotating the control handwheel 402 drives the control threaded rod 401 to rotate, and adjusting the control threaded rod 401 drives the micro switch 403 to adjust the height. If the patient experiences hypoxia, fatigue, or a short breathing interval, and the blowing air pressure can no longer push the stop ball 303 to drive the sliding shaft 302 to touch the micro switch 403, the alarm indicator light 106 will not light up, which also reminds the patient to rest before training to avoid overtraining and injury. The higher the height of the micro switch 403 is adjusted, the lower the air pressure required for the patient to blow, thus making it easier for the patient to adjust according to their own situation.

[0045] In Example 2, based on Example 1, the abdominal breathing prompting module 5 includes: a prompting piston cylinder 501 and a piston column 502, wherein the side of the prompting piston cylinder 501 is made of iron.

[0046] The side of the prompt piston cylinder 501 is magnetically connected to the magnet on the side of the connecting tube 105; the side of the prompt piston cylinder 501 is attached to the connecting tube 105; a piston rod 502 is slidably sleeved inside the prompt piston cylinder 501; the piston rod 502 is used to indicate the abdominal undulations; the prompt piston cylinder 501 is provided with scale lines.

[0047] The abdominal connector 6 includes: an abdominal pressure control shell 601, an abdominal wrapping strap 602, and a needle-face hook and loop fastener 603. The side of the abdominal pressure control shell 601 is connected to the prompt piston cylinder 501 via a hose. The abdominal wrapping strap 602 is fixedly installed on the abdominal pressure control shell 601. The needle-face hook and loop fastener 603 is fixedly installed on the abdominal wrapping strap 602.

[0048] The pneumatic connector 7 includes: a pneumatic slider 701, a connecting strap 702, a hook and loop fastener 703, and a return spring 704. The pneumatic slider 701 is sealed and inserted into the abdominal pneumatic control shell 601. The connecting strap 702 is fixedly installed on the pneumatic slider 701, and the hook and loop fastener 703 is fixedly installed on the connecting strap 702. The hook and loop fastener 703 is used to connect the hook and loop fastener 603. The return spring 704 is fixedly installed on the inner side of the pneumatic slider 701, and the other end of the return spring 704 is fixedly installed on the inner side of the abdominal pneumatic control shell 601. The pneumatic connector 7 can be worn on the patient's abdomen in conjunction with the abdominal connector 6. It can be used to detect the degree of abdominal movement of the patient during breathing training, making it easier for the patient to perform abdominal breathing and improving the effect of breathing training. The piston cylinder 501 adopts a magnetic connection method and modular assembly, which makes it more flexible to use, improves the quality of the patient's breathing training, and improves the standardization of the patient's breathing training. The piston column 502 can be used to quickly and easily determine the degree of abdominal undulation without the patient having to feel it by touch.

[0049] This invention provides a modular breathing training device, the specific operation method of which is as follows:

[0050] Step S1: First, place the breathing access device 1 on the table. The patient uses the mouthpiece on the corrugated tube 204 to practice blowing and inhaling. During the process, the airflow causes the floating balls 104 to float up. Observe the number of floating balls 104 floating up and the duration. Breathing resistance training can then be carried out. Using the one-way flow device 3, during inhalation, the bottom stop ball 303 is in contact with the bottom one-way limiting ring 202 under the action of air pressure to stop the inhalation. The upper stop ball 303 will move down under the action of air pressure and separate from the one-way limiting ring 202. At this time, the airflow flows through the connecting tube 105. The three floating balls 104 are drawn in. At this time, with the elastic traction of the tension spring 304, the upper stop ball 303 automatically moves up and resets when the patient stops inhaling.

[0051] In step S2, when the patient exhales, the upper stop ball 303 adheres tightly to the upper one-way limiting ring 202 under the action of air pressure, and the lower stop ball 303 moves downward and separates from the lower one-way limiting ring 202 under the action of air pressure. At this time, the airflow can blow up the three floating balls 104 through the cavity of the bottom plate 101.

[0052] In step S3, when the patient is undergoing breathing training, the through hole at the top of the connecting tube 105 and the through hole at the bottom of the base plate 101 respectively serve to relieve pressure and ensure airflow. The two one-way flow components 3 ensure that the patient can flexibly switch between exhalation and inhalation.

[0053] In step S4, rotating the control handwheel 402 drives the control threaded rod 401 to rotate, adjusting the control threaded rod 401 to adjust the height of the micro switch 403. When the patient exhales, the air pressure pushes the bottom stop ball 303 to drive the sliding shaft 302 to touch the micro switch 403. At this time, the micro switch 403 circuit control alarm indicator 106 lights up, indicating that the vital capacity air pressure is within the target range. If the patient experiences hypoxia, fatigue, or a short breathing interval, and the exhalation air pressure can no longer push the bottom stop ball 303 to drive the sliding shaft 302 to touch the micro switch 403, the alarm indicator 106 will not light up, indicating that the patient needs to rest before training. The connecting strap 702 is wrapped around the patient's abdomen with the abdominal wrapping strap 602, and then secured with the needle-face hook and loop fastener 603 and the loose-face hook and loop fastener 703.

[0054] In step S5, when the patient is breathing abdominally, the abdomen will expand and contract. At this time, the air pressure slider 701 can be squeezed and moved outward on the abdominal air pressure control shell 601. With breathing, the patient's abdomen contracts. At this time, under the pull of the reset spring 704, the air pressure slider 701 can retract and reset. During the process, the air pressure generated inside the abdominal air pressure control shell 601 is introduced into the prompt piston cylinder 501. The piston column 502 inside the air pressure control prompt piston cylinder 501 can then move. The distance of movement of the piston column 502 can be observed to show whether the abdominal contraction during abdominal breathing meets the standard.
