Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to a pulmonary rehabilitation training device and a method for using the same. Background Art

[0002] Clinically, there are many patients with chronic respiratory diseases such as chronic obstructive pulmonary disease, bronchial asthma, interstitial lung disease, etc., patients with impaired respiratory muscle function caused by neuromuscular diseases such as spinal cord injury, myasthenia gravis, muscular dystrophy, etc., and patients with abnormal lung function after cardiothoracic and abdominal disease surgery. These patients mainly show abnormal breathing patterns, such as shallow and rapid breathing and paradoxical contraction of the chest and abdomen during the respiratory cycle, and decreased respiratory muscle contraction function, such as atrophy of the respiratory muscles, and decreased respiratory muscle strength and endurance, which leads to a decline in the patients' daily activity ability and quality of life, causing great trouble to their families and society.

[0003] Respiratory rehabilitation training is recognized by domestic and international guidelines for the diagnosis and treatment of related diseases. Human respiratory movements include internal and external movements of the lungs. The internal movement of the lungs is mainly the contraction and expansion of the airways and alveoli. If the internal movement of the lungs is impaired, it is mainly achieved with the help of a ventilator. The ventilator ventilates by delivering gas into the body. Common ventilators include constant pressure, constant volume, or timed ventilators. The external movement of the lungs is mainly assisted by abdominal movement and thoracic movement, specifically the diaphragm, abdominal muscles and intercostal muscles. If the external movement of the lungs is impaired, it is mainly through abduction of the two upper limbs, expansion of the thorax, abdominal pressure exercises and stimulation of the phrenic nerve to help the trainee complete the external movement of the lungs. When inhaling, the two upper limbs need to be abducted, the thorax needs to be expanded, abdominal pressure exercises are required, and the diaphragm needs to be contracted.

[0004] Severely ill trainees, such as patients in deep coma, have problems with breathing patterns, respiratory movements, or both. Breathing pattern training and respiratory movement training can be used to improve lung function, promote recovery from lung diseases, and reduce the incidence and mortality of lung diseases. Breathing pattern training is proposed for the shallow and rapid breathing patterns and contradictory chest and abdominal movements in the respiratory cycle. Respiratory therapists guide trainees to adjust their breathing frequency and breathing depth and sequentially activate the chest and abdominal respiratory muscles with their bare hands or with the help of instruments, so that trainees can rebuild physiological and orderly deep and slow breathing patterns, thereby reducing breathing-related oxygen consumption and lung overinflation, correcting chest and abdominal contradictory respiratory activities, and relieving trainees' shortness of breath symptoms; respiratory movement training is a combination of internal and external lung movements, training the trainees' airway and alveolar contraction and expansion movements, as well as chest and abdominal movement training, so that the contraction and expansion movements of the airways and alveoli have a certain depth and elasticity, and increase the strength and endurance of the chest and abdominal movement muscles.

[0005] Existing pulmonary rehabilitation training mainly focuses on the internal movement of the lungs, such as ventilators. Because it fails to combine external movement training of the lungs, it cannot achieve the best pulmonary rehabilitation training effect. Some trainees have spontaneous breathing and do not need ventilators to help with internal movement of the lungs. They only need external movement of the lungs. However, there are few ideal rehabilitation training devices on the market that assist external movement of the lungs, or they have not yet appeared. Summary of the invention

[0039] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the protection scope of the present invention.

[0041] The upper limb exercise device 30 includes a chest support 31 and two sets of upper limb pneumatic components 32. The inner side of the chest support 31 forms a wearing cavity 311, and the chest support 31 is worn on the chest through the wearing cavity 311. The two sets of upper limb pneumatic components 32 are arranged on both sides of the chest support 31. Figure 2 , 3 Each upper limb pneumatic assembly 32 includes a first air bag 321 and an upper limb strap 322. The first air bag 321 is connected to the air compressor through the first air inlet and outlet pipe 51. One end of the first air bag 321 is connected to the chest support 31, and the other end is provided with the upper limb strap 322. An elastic band 301 is provided between the upper limb strap 322 and the chest support 31 to connect the two. The upper limb strap 322 is used to be worn on the elbow. Please refer to Figure 4 The abdominal exercise device 40 includes an abdominal strap 41 and a second air bag 42 arranged on the inner side of the abdominal strap 41. The abdominal strap 41 is used to be worn on the abdomen so that the second air bag 42 fits the abdomen. The second air bag 42 is connected to the air compressor through the second air inlet and outlet pipes 52 to cooperate with the respiratory movement frequency sensed by the respiratory rate sensor 20. The air compressor drives the first air bag 321 and the second air bag 42 to expand and contract, so that the upper limbs and the abdomen move with the respiratory movement frequency, thereby helping the trainee to recover lung function and restore effective and regular breathing.

[0042] Please refer again Figure 2 The chest support 31 is provided with a torso width section 60 between the two sides, and the width of the wearing cavity 311 is adjusted through the torso width section 60 to adapt to the physique of different trainees. The torso width section 60 includes two docking plate sections 61 and an adjustment component 62 for connecting the two docking plate sections 61. The adjustment component 62 includes a latch member 621, a pin sleeve 622 and a fixing member 623. The latch member 621 and the pin sleeve 622 are arranged on the two docking plate sections 61 opposite to each other, one end of the latch member 621 is inserted into the pin sleeve 622, and the fixing member 623 is installed on the pin sleeve 622 to fix the connection after the latch member 621 is inserted into the pin sleeve 622.

[0043] The torso width section 60 adjusts the width of the wearing cavity 311 by loosening the fixing piece 623, adjusting the length of one end of the latch piece 621 inserted into the pin sleeve 622, and then re-locking the fixing piece 623, so as to adjust the distance between the two docking plate sections 61 to adjust the width of the wearing cavity 311.

[0044] The chest support 31 is provided with side panel sections 63 on both sides opposite to each other. The side panel sections 63 are L-shaped, including a connecting section 631 and a flat section 632. The connecting section 631 is roughly vertically connected to the docking plate section 61. The outer side of the connecting section 631 is connected to one end of the corresponding first airbag 321 so that the wearing cavity 311 can be worn on the chest cavity. The two connecting sections 631 are relatively clamped on both sides of the trainer's chest cavity to play a clamping and fixing role. The flat section 632 is used to support the upper limbs, so that the upper limbs can swing on the flat section 632 driven by the first airbag 321.

[0045] Furthermore, the first airbag 321 and the second airbag 42 are both formed by combining a single or multiple sub-airbags, and the sub-airbags are made of elastic material.

[0046] Furthermore, the shape of the first airbag 321 is related to the movement trajectory of the two upper limbs, and the shape of the second airbag 42 is related to the shape of the abdomen. Both the first airbag 321 and the second airbag 42 can be arc-shaped, so that when the air compressor drives the first airbag 321 and the second airbag 42 to expand and contract, the upper limbs and the abdomen move along with the expansion and contraction of the first airbag 321 and the second airbag 42.

[0047] Furthermore, an airbag pressure sensor 501 may be provided on both the first air inlet and outlet pipe 51 and the second air inlet and outlet pipe 52 to detect the abdominal airbag pressure.

[0048] Furthermore, the host 10 is provided with a touch control screen 11 , which is electrically connected to the respiratory rate sensor 20 and the airbag pressure sensor 501 , respectively, so as to receive and display data detected by the respiratory rate sensor 20 and the airbag pressure sensor 501 .

[0049] The pulmonary rehabilitation training device also includes an external diaphragm pacemaker 70 and a ventilator. The host 10 is provided with an electrical stimulation device, which is electrically connected to the electrode sheet placed at an appropriate position on the trainee's chest, forming an external diaphragm pacemaker 70. The host 10 is provided with a ventilation device, which is connected to the trainee's mask or endotracheal tube through the third inlet and outlet 53, forming a ventilator 80.

[0050] It can be understood that the pulmonary rehabilitation training device may not be installed with the external diaphragm pacemaker 70 and the ventilator, and a simplified version of the pulmonary rehabilitation training device may be formed by the host 10, the respiratory rate sensor 20, the upper limb exercise device 30 and / or the abdominal exercise device 40. An external diaphragm pacemaker 70 and a ventilator may also be additionally installed to form other versions of the pulmonary rehabilitation training device in combination with the host 10, the respiratory rate sensor 20, the upper limb exercise device 30 and the abdominal exercise device 40.

[0051] See also Figure 1 , Figure 6 The method for using the pulmonary rehabilitation training device comprises the following steps:

[0052] According to the degree of lung dysfunction of the trainee, the corresponding lung rehabilitation training program is adopted. Pulmonary rehabilitation exercises include internal lung exercises and external lung exercises. The former are such as the contraction and expansion of alveoli and airways, and the latter are the exercises of respiratory muscles, namely abdominal exercises and thoracic exercises. The specific standards of the lung rehabilitation training program adopted are:

[0053] For patients with severe pulmonary dysfunction: if the trainee does not breathe spontaneously, they will be given upper limb and abdominal exercises, combined with ventilation exercises and diaphragm pacing exercises;

[0054] Moderate lung function impairment: If the trainee has shallow spontaneous breathing, upper limb exercise, and / or abdominal exercise, and / or diaphragm pacing exercise are given;

[0055] For patients with mild lung dysfunction: give upper limb exercises and / or abdominal exercises.

[0056] During rehabilitation training for patients with severe lung dysfunction,

[0057] Step 1, preparation for double upper limb exercise: the trainee lies on the bed, adjusts the width of the wearing cavity 311 of the chest support 31 to adapt to trainees of different body shapes, wears the chest support 31 on the chest through the wearing cavity 311, the torso width section 60 is located above the chest, the connecting sections 631 of the two side plate sections 63 relatively clamp the two sides of the chest, the two upper limb straps 322 are relatively worn on the two upper limbs, and the two upper limbs are relatively placed on the flat plate sections 632 of the two side plate sections 63; the first inlet and outlet air pipes 51 are relatively connected to the first airbag 321 and the air compressor;

[0058] Step 2, abdominal exercise preparation: the abdominal band 41 is worn on the abdomen, and the second air bag 42 is attached to the abdomen; the second air inlet and outlet pipe 52 is relatively connected to the second air bag 42 and the air compressor, and the respiratory rate sensor 20 is attached to the appropriate position of the trainee's chest;

[0059] Step 3, diaphragm pacemaker preparation: attach two pairs of electrodes of the external diaphragm pacemaker 70 to appropriate positions of the trainee's chest and connect them to the electrical stimulation device;

[0060] Step 4, ventilator preparation: connect the mask or endotracheal tube used by the trainee to the ventilator through the third inlet and outlet tubes 53;

[0061] Step 5: Match the upper limb movement driving frequency, abdominal movement auxiliary frequency, ventilator frequency, and diaphragm pacing frequency with the trainee's breathing frequency obtained through the respiratory rate sensor 20 and start working. Specifically, when inhaling, the upper limbs are abducted, the abdomen is pressurized, the diaphragm is paced and contracted, and the ventilator blows into the lungs.

[0062] It is understandable that, depending on the severity of the illness, when a simplified version of the pulmonary rehabilitation trainer is used, steps 3 / 4 are not required, and step 5 is only for the upper limb exercise device 30 and / or the abdominal exercise device 40 to match the trainee's breathing rate obtained by the breathing rate sensor 20 and start working.

[0063] If the patient does not have spontaneous breathing, or the breathing is weak, the respiratory rate sensor 40 cannot detect the respiratory rate, and then the respiratory rate of a normal person is matched and started.

[0064] It is understood that the upper limb exercise device 30 or the abdominal exercise device 40 can be an electric drive device, and the electric upper limb exercise device 30 is arranged on both sides of the chest support 31, and the upper limbs are swung by electric drive. The electric abdominal exercise device 40 is driven by electric components to assist abdominal exercise.

[0065] In summary, the pulmonary rehabilitation training device and the method of use of the present invention are easy to operate, can effectively help the trainee achieve an effective and regular breathing method, improve the strength and endurance of the respiratory motor muscles, and are easy to promote and apply to the community and family due to its easy operation, thereby improving the participation and compliance of the trainees.
