[0002] With the cross-fusion of rehabilitation medicine and biomedical engineering, the rehabilitation assessment of testers such as stroke and cardiopulmonary disease gradually develops towards "multidimension, precision and integration".

The test mode has the problem of low evaluation efficiency due to the complicated operation process. SUMMARY

[0021] 1. The cardiopulmonary detection unit comprises a first covering structure and a cardiopulmonary detection component. The first covering structure is installed on the test subject's bed. The cardiopulmonary detection component is installed within the first covering structure, which covers the test subject's chest area and allows the cardiopulmonary detection component to collect the test subject's cardiopulmonary information. The first covering structure both supports the cardiopulmonary detection component for information collection and secures the test subject's chest area through detachable fastening (Velcro, clips, etc.) to the test subject's bed. This design allows the cardiopulmonary detection unit to detect the test subject's cardiopulmonary status while simultaneously securing the test subject and preventing them from slipping off the bed.

[0026] The application will be further described below in conjunction with the drawings and specific embodiments, it should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments without conflict.

[0027] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present. As used herein, the terms "vertical", "horizontal", "left", "right" and similar terms are used for explanation only and not to limit the embodiments.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0029] Referring to Figures 1-2 , the application is an intelligent cardiopulmonary exercise test and surface electromyography test integrated device, comprising a bearing unit 1, a cardiopulmonary detection unit, an electromyography detection unit and a control system.

[0030] The bearing unit 1 comprises a frame 11 and a tester lying bed 12, and the tester lying bed 12 is supported by the frame 11. The frame 11 is a main supporting base and has a rectangular structure as a whole. The tester lying bed 12 is installed on the top of the frame 11 (it can be inclined or flat lying, which is selected according to actual needs) and is fixed by detachable bolts to avoid sliding off the frame 11.

[0031] The heart-lung detection unit comprises a first covering structure 2 and a heart-lung detection component. The first covering structure 2 is installed on the test bed 12. The first covering structure 2 (such as an adjustable chest strap, a vest-type fixing sleeve, a magnetic chest support, etc.) is installed on the corresponding chest area of the test bed 12. The heart-lung detection component is installed in the first covering structure 2. The first covering structure 2 is used to cover the chest area of the test subject, and the heart-lung detection component collects the heart-lung information of the test subject. The heart-lung detection component (such as a combination of a chest patch type ECG sensor and a strain type breathing sensor, a combination of a multi-channel ECG electrode array and a capacitive breathing sensor, an integrated heart-lung sensor patch, etc.) simultaneously covers the test subject and detects the heart-lung of the test subject, and collects the corresponding information. At the same time, the first covering structure 2 can also fix the test subject to prevent the test subject from slipping off the test bed (when the test bed is inclined). In addition, it should be noted that the heart-lung detection needs to detect a lot of content, and if necessary, the corresponding detection equipment can be added, such as a pulse oximeter (used to monitor blood oxygen saturation, reflecting oxygenation function), a transcutaneous carbon dioxide partial pressure sensor (used to monitor gas exchange efficiency), an expiratory flow sensor (used to evaluate lung ventilation function), etc. The newly added detection equipment can be adapted to the first covering structure 2 through buckling, magnetic attraction or wire adapter without changing the core architecture of the device, and all use non-invasive design to ensure the comfort of the test subject.

[0032] The electromyography detection unit comprises a second covering structure 3 and an electromyography detection component. The electromyography detection component is installed in the second covering structure 3. The second covering structure 3 is used to cover the leg area of the test subject, and the electromyography detection component collects the leg electromyography information of the test subject. The second covering structure 3 (such as an adjustable leg strap, a leg sleeve type fixing sleeve, a magnetic leg support, etc.) can adapt to the leg movement of the test subject, facilitate the internal electromyography detection component (such as a needle-shaped dry electrode, a flexible wet electrode array, an integrated electromyography sensor patch, etc.) to detect the leg electromyography of the test subject in the movement state, and collect electromyography information. The heart-lung detection unit and the electromyography detection unit work together to detect the heart-lung and the leg electromyography at the same time, collect the corresponding information, and improve the evaluation efficiency of the related data.

[0033] The control system is electrically connected to the heart-lung detection unit and the electromyography detection unit. The control system can receive the heart-lung information and the electromyography information from the heart-lung detection unit and the electromyography detection unit at the same time, analyze and process them, and finally output the related data reflecting the heart-lung function state and the leg muscle activity state of the test subject, providing complete data support for test evaluation.

[0034] The working principle of the intelligent cardiopulmonary exercise test and surface electromyography test integrated device is as follows: first, the device is deployed to the test area, the tester lies on the tester lying bed 12 of the bearing unit 1, the chest area of the tester is covered by the first covering structure 2 (such as an adjustable chest bandage), the leg area of the tester is covered by the second covering structure 3 (such as an adjustable leg bandage), and the two types of detection components are ensured to be attached to the chest collection area and the leg target muscle group respectively; then, the posture of the bearing unit 1 is adjusted (horizontal or inclined state) according to the test requirements, and the tester can actively perform or assist in leg movement. In this process, the cardiopulmonary detection unit collects cardiopulmonary information such as the heart rate and respiratory rate of the tester in real time, the electromyography detection unit synchronously captures electromyography information such as the amplitude and discharge frequency of the leg muscle, the information collected by the cardiopulmonary detection unit and the electromyography detection unit is synchronously transmitted to the control system, the information is analyzed and processed by the control system, the correlation analysis of the cardiopulmonary information and the electromyography information is realized, and finally the control system outputs integrated data reflecting the cardiopulmonary function compensation state and the leg muscle activity coordination of the tester.

[0035] Preferably, the installation mode between the first covering structure 2 and the tester lying bed 12 is detachable fixed installation (magic tape, buckle and the like), which facilitates the change of the position of the first covering structure 2 when facing testers with special height or conditions (such as height greater than two meters or dwarfism), ensures that the test can be performed, and at the same time ensures the stable connection between the first covering structure 2 and the tester lying bed 12, and ensures that the tester stably lies on the tester lying bed 12. As an alternative to the detachable fixed installation, the first covering structure 2 and the tester lying bed 12 are not detachably fixedly connected, such as rivet riveting type fixation: the frame (enhanced nylon material) of the tester lying bed 12 is pre-provided with a riveting hole, the installation edge band (for installing a rivet) of the first covering structure 2 is provided with a through hole corresponding to the riveting hole, a core-pulling rivet is used to pass through the through hole and the riveting hole for riveting fixation, and the rivet is formed after riveting. The mechanical connection is not detachable. Compared with the detachable fixed mode, the non-detachable fixed connection is more stable.

[0036] Based on the cardiopulmonary detection unit including the first covering structure 2 and the cardiopulmonary detection component, the first covering structure 2 is installed on the tester lying bed 12. The cardiopulmonary detection component is installed in the first covering structure 2, the first covering structure 2 is used for covering the chest area of the tester, and the cardiopulmonary detection component collects the cardiopulmonary information of the tester. The first covering structure 2 not only bears the cardiopulmonary detection component to realize the collection of the cardiopulmonary information, but also realizes the covering and fixation of the chest area of the tester through the detachable fixation (magic tape, buckle and the like) with the tester lying bed 12. Such design can not only make the cardiopulmonary detection unit detect the cardiopulmonary state of the tester, but also fix the tester to prevent the tester from sliding off the tester bed 12. Therefore, the cardiopulmonary detection unit can not only test the cardiopulmonary state, but also fix the tester, and has the functions of one object and two uses.

[0037] The cardiopulmonary detection unit comprises a first covering structure 2 and a cardiopulmonary detection component, the first covering structure 2 is installed on the tester lying bed 12, the cardiopulmonary detection component is installed in the first covering structure 2, the first covering structure 2 is used for covering the chest region of the tester, and the cardiopulmonary detection component collects the cardiopulmonary information of the tester. The electromyography detection unit comprises a second covering structure 3 and an electromyography detection component, the electromyography detection component is installed in the second covering structure 3, the second covering structure 3 is used for covering the leg region of the tester, and the electromyography detection component collects the leg electromyography information of the tester; the control system is electrically connected with the cardiopulmonary detection unit and the electromyography detection unit respectively. The cardiopulmonary detection unit, the electromyography detection component and the control system cooperate with each other to realize the synchronous collection, synchronous reception and synchronous analysis of the cardiopulmonary information and the leg electromyography information, solve the pain points of the traditional separate equipment that the data collection is not synchronized and the correlation is poor, and improve the evaluation efficiency of the tester.

[0038] Preferably, the tester lying bed 12 is pivoted to the frame 11 through a pivoting shaft, so that the tester lying bed 12 can be switched between a horizontal state and an inclined state; the tester lying bed 12 is fixed in the inclined state through a locking structure. The horizontal state can meet the basic cardiopulmonary and electromyography data collection in the resting state, and the inclined state can simulate the body posture in daily activities (such as standing and walking) or rehabilitation training, adapt to all scene requirements, and make the test no longer limited to a single posture, and the evaluation dimension is more comprehensive. The lying bed is fixed in the inclined state through the locking structure (such as a latch type locker, an electromagnetic lock, a ratchet and pawl type locking mechanism or a threaded locking type locking structure), which can accurately lock the target inclination angle and avoid accidental shaking or displacement of the lying bed during the test. It not only guarantees the safety of the tester (especially the rehabilitation patients with difficulty in moving), but also reduces the displacement of the detection component and the signal distortion caused by the posture fluctuation, greatly improves the stability and reliability of the data collection in the motion state.

[0039] Preferably, the tester lies on the bed 12, which comprises an upper supporting bed 121 and at least two lower supporting beds 122, both of which are pivotally connected to the lower end of the upper supporting bed 121 in the inclined state, and are arranged at intervals along the width direction of the upper supporting bed 121; the first covering structure 2 is installed on the upper supporting bed 121; both of the lower supporting beds 122 are provided with the second covering structure 3. The pivot shaft is arranged on the back of the upper supporting bed 121, and in this structure, the upper supporting bed 121 can be switched between the horizontal state and the inclined state relative to the frame 11. The upper supporting bed 121 stably supports the upper body of the tester, and the two lower supporting beds 122 independently swing through the pivotal structure and are arranged at intervals along the width direction, which not only avoids mutual interference when the lower limbs move, but also simulates the alternating movement of the lower limbs in the natural gait of the human body, so that the dynamic test such as stepping is more in line with the daily activity posture. Compared with the traditional whole bed, this design can reduce the feeling of being bound, so that the muscle exertion and cardiopulmonary compensation of the tester in the movement state are closer to the real scene, and the test data has more reference value. After the tester lies down, the first covering structure 2 for fixing the chest can be directly arranged on the upper supporting bed 121, and the second covering structure 3 for fixing the left and right legs can be arranged on the two lower supporting beds 122, without the need for additional adjustment of the position of the detection component. Compared with the cluttered installation of the separated equipment or the whole bed body, this design makes the wearing and positioning of the detection unit more orderly, and one person can quickly complete the preparation work, significantly shortening the preparation time before the test and further improving the evaluation efficiency.

[0040] Preferably, the lower end of the upper supporting bed 121 in the inclined state is connected with a stepping motion mechanism 4, and the lower supporting bed 122 is located between the upper supporting bed 121 and the stepping motion mechanism 4. The stepping motion mechanism 4 (such as a crank connecting rod type stepping mechanism, a cam type stepping mechanism, etc.) can drive the lower limbs of the tester to move periodically, without the need for additional construction of an independent motion device or manual auxiliary motion. At the same time, the lower supporting bed 122 as an intermediate carrier for power transmission can disperse the driving force of the stepping motion mechanism 4, avoiding local stress concentration; the direct connection of the upper supporting bed 121 and the stepping motion mechanism 4 ensures the structural rigidity and movement stability, and reduces the loosening or wear caused by long-term dynamic test. Compared with the traditional indirect transmission structure, the stress path of this design is simpler, the mechanical loss is smaller, which can prolong the service life of the equipment and reduce the maintenance cost.

[0041] Preferably, the upper supporting bed 121 and the stepping exercise mechanism 4 are connected in sliding connection, so that the stepping exercise mechanism 4 can be away from or close to the upper supporting bed 121. The distance between the stepping exercise mechanism 4 and the upper supporting bed 121 is adjustable (adjustment range 0-25 cm) through the sliding connection, which can accurately adapt to the length of the lower limbs of testers of different heights (covering the height of 145-195 cm population). Compared with the fixed distance design, the tester does not need to deliberately adjust the body posture to make the lower limbs naturally fit the lower supporting bed 122, avoiding the motion constraint or abnormal test posture caused by the mismatch of leg length, so that children, adults and testers of different body types can all have a comfortable test experience, significantly expanding the applicable population of the device.

[0042] In addition, the intelligent cardiopulmonary exercise test and surface electromyography test integrated device further comprises a tilting driving mechanism, a driving end of the tilting driving mechanism is drivingly connected with the pivot shaft, and the control system is electrically connected with the tilting driving mechanism. The tilting driving mechanism can be arranged at the back region of the tester bed (close to the pivot shaft), the driving end of the tilting driving mechanism is directly drivingly connected with the pivot shaft, and the inclination angle of the tester bed 12 can be automatically adjusted by the control system, replacing the traditional manual lifting and supporting adjustment mode. Without manual force or additional tools, only by inputting the target angle (such as 0°-60°) through the control system, the tester bed can be smoothly tilted and fixed by cooperating with the locking structure, greatly reducing the labor cost. It is especially suitable for rehabilitation patients with difficulty in movement or high-frequency test scenes, and a single person can complete the posture adjustment, significantly shortening the test preparation time and improving the overall test evaluation efficiency.

[0043] Preferably, the first covering structure 2 is an elastic chest band 7, and the cardiopulmonary detection component is a combination of an ECG electrode module and a respiration sensing module. The elastic chest band 7 can closely fit the physiological curved surface of the tester's chest by virtue of its own elastic tension, adapt to different chest types (covering 70-130 cm chest circumference), and firmly fix the ECG electrode module to the target collection area (such as the sternum, the left and right clavicular midlines) of the chest, avoiding electrode displacement in the motion state; at the same time, the wrapping of the elastic band can reduce the relative sliding of the skin and the electrode caused by the respiratory movement and the limb swing, greatly reducing the motion artifact interference. The elastic band cooperates with the respiration sensing module (such as a capacitive type or a strain type) to synchronously collect respiration information, and the two types of components form a heart and respiration synchronous collection system under the fixation of the elastic band.

[0044] Preferably, the second covering structure 3 is an elastic leg band 8, and the elastic leg band 8 is provided with electrode positioning grooves corresponding to the lower limb muscle groups of the tester; the electromyography detection component is a plurality of surface electromyography electrodes, and the electrode positioning grooves are matched with the surface electromyography electrodes. The elastic leg band 8 is accurately matched with the surface electromyography electrodes through the pre-set electrode positioning grooves, realizes double limiting of electrode physical clamping and elastic fixing, the shape and size of the grooves are completely matched with the surface electromyography electrodes, the electrode transverse sliding or rotation is avoided, and at the same time, the tension of the elastic leg band 8 tightly adheres to the lower limb skin, so that the contact between the surface electromyography electrodes and the target muscle groups is stable. Even in dynamic scenes such as stepping, the electrodes will not be displaced due to limb swinging and muscle contraction and relaxation, the motion artifact interference is greatly reduced, and the accuracy and repeatability of electromyography signal (such as amplitude and discharge frequency) acquisition are significantly improved.

[0045] Preferably, the tester lying on the bed 12 is provided with a folding handrail 5. The folding handrail 5 provides a stable support point for the tester (especially the patients in recovery period, the elderly and the people with limited lower limb function), and the tester can hold the handrail to assist in adjusting the body posture when lying down, and the tester can use the folding handrail to support when getting up, so as to effectively avoid the risk of falling and slipping due to limb weakness or smooth bed surface. Compared with the design without a handrail, the safety of the tester when getting on and off the bed and adjusting the posture is greatly improved, the assistance intensity of the operator is reduced, and the design is especially suitable for the rehabilitation patients with difficulty in moving to independently complete the basic actions.

[0046] Preferably, the bottom of the frame 11 is provided with lockable casters 6. The lockable casters 6 at the bottom of the frame 11 provide flexible movement capability for the device, and the device can be freely moved in the test site by a single person without the need for multiple people to carry or the use of lifting equipment, so that the device can be quickly deployed in different rooms (such as a rehabilitation evaluation room and a physical examination room) and different test areas. Compared with the fixed frame 11 without casters, the labor cost and time cost of transferring the device are greatly reduced, and the utilization rate of the equipment is improved.
