Description

Technical Field

[0001] This invention relates to the field of sputum expectoration technology, specifically to an intelligent postural vibration sputum expectoration device. Background Technology

[0002] In clinical medicine, sputum accumulation is a very common complication in patients with respiratory diseases, postoperative bedridden patients, and long-term disabled bedridden individuals. Its incidence remains high in these special populations, posing a significant threat to their recovery and life safety. If sputum cannot be expelled from the body in a timely and effective manner, it will gradually accumulate and dry in the airways, eventually obstructing them and severely affecting the lungs' gas exchange function, leading to decreased blood oxygen saturation and carbon dioxide retention. This can not only worsen lung infections and induce life-threatening conditions such as acute respiratory distress syndrome and respiratory failure, but also significantly increase the patient's physical suffering, raise the difficulty and cost of clinical treatment, prolong hospital stays, and increase the consumption of medical resources. Therefore, scientific, standardized, and effective sputum clearance care is crucial for the control of the condition and the recovery prognosis of these patients, and is an indispensable core aspect of clinical nursing work.

[0003] Currently, commonly used sputum clearance methods in clinical practice are mainly divided into two categories: manual percussion sputum clearance and mechanical sputum clearance equipment-assisted sputum clearance. Both methods have their applications in different scenarios, but each has certain limitations. Among them, manual percussion sputum clearance, as a traditional method, is still widely used in primary healthcare institutions and emergency situations due to its ease of operation and lack of the need for special equipment. This method relies on manual operation by medical staff or nurses who use their hands in a hollowed-out position to percuss the patient's back, using the vibration generated to loosen sputum in the airway and promote its expulsion through the cough reflex. However, with the increasing demands of clinical nursing, the obvious limitations of this traditional method have become increasingly apparent. The force, frequency, duration, and site of action of the percussion depend entirely on the personal experience and operating habits of medical staff. The consistency of operation among different personnel, and even among the same personnel at different times, is extremely poor. It is difficult to accurately target the stagnant sputum deep in the airway, and it can only loosen the sputum on the surface, resulting in a relatively limited overall sputum clearance efficiency. At the same time, for patients who are bedridden for a long time, physically weak, or have spinal injuries, manually adjusting their position is not only time-consuming and laborious, requiring the cooperation of multiple nurses, but it is also difficult to maintain the optimal sputum clearance position that conforms to the patient's spinal physiological curve, the severity of the condition, and the location of sputum accumulation for a long time after adjustment. The problem of insufficient positional adaptability further restricts the sputum clearance effect, and may even aggravate the patient's discomfort or condition due to improper positioning.

[0004] To effectively overcome the inherent shortcomings of manual sputum clearance and meet the clinical demand for efficient and standardized sputum clearance care, various mechanical sputum clearance devices have emerged. Among them, vibration sputum clearance devices, with their relatively simple operation and stable vibration effect, are widely used in medical institutions at all levels and have become one of the mainstream devices to replace manual percussion sputum clearance. Most existing vibration sputum clearance devices generate regular vibrations through a built-in single vibration module, which is then transmitted to the patient's back via a contact panel. While this can replace manual percussion to some extent, reducing the physical exertion of nursing staff and improving operational convenience and standardization, there are still many technical shortcomings that urgently need to be addressed in actual clinical application. In terms of body positioning, most traditional vibration sputum clearance devices use a fixed support structure that can only provide a single tilt angle. They cannot be flexibly adjusted according to the patient's height, weight, body shape, and individual characteristics of the spine's physiological curve. For obese, thin, scoliosis, or postoperative spinal fixation patients, it is difficult to achieve precise fit and effective support. This not only affects the transmission efficiency of vibration force but may also cause local skin pressure, muscle soreness, or even increase the burden on the spine due to improper contact, resulting in obvious limitations in clinical application. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent postural vibration sputum clearance device to solve the problem that existing vibration sputum clearance devices cannot flexibly adjust the tilt angle and are difficult to adapt to patients of different body types.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent body position vibration sputum expectoration device, comprising a support assembly and a vibration adjustment assembly, wherein the support assembly comprises a support plate and a base plate, and the support plate and the base plate are rotatably connected by a hinge seat;

[0007] The vibration adjustment assembly includes two fixed plates, with a dual-axis motor positioned between them. Each output end of the dual-axis motor has a cam. A first connecting rod is rotatably connected to each cam, and a second connecting rod is rotatably connected to the first connecting rod. The other end of the first connecting rod is rotatably mounted on the fixed plate via a fixed shaft. A telescopic component is mounted on the top of the second connecting rod. A horizontal plate is fixedly connected to the fixed plate, and a mounting base is fixedly connected to the horizontal plate. A vertical rod is fixedly connected to the telescopic component, and a second hinge seat is rotatably connected to the top of the vertical rod. The second hinge seat is fixed to a support plate. Eccentric wheels are driven to each output end of the dual-axis motor, and the cams on both sides are fixed to the eccentric wheels.

[0008] Furthermore, the base plate is horizontally positioned, and the support plate is inclinedly positioned on top of the base plate.

[0009] Furthermore, the support assembly and vibration adjustment assembly are enclosed inside the foam cover, and a control panel is installed on one side of the foam cover.

[0010] Furthermore, the two fixing plates are symmetrically and vertically fixed to the top of the base plate, and the dual-axis motor is mounted on the top of the support plate.

[0011] Furthermore, the second connecting rod is vertically mounted on the first connecting rod, and the second connecting rod is positioned at the middle of the first connecting rod.

[0012] Furthermore, the telescopic end of the telescopic component is rotatably connected to the second connecting rod, and the telescopic end of the telescopic component is slidably embedded inside the mounting base.

[0013] Furthermore, the horizontal plate is vertically mounted on the fixed plate, and the horizontal plate is positioned near the top of the fixed plate.

[0014] Furthermore, the two fixing plates are disposed between the support plate and the base plate, and the size of the sponge cover is adapted to the support plate and the base plate.

[0015] Compared with existing technologies, the beneficial effects of the intelligent postural vibration sputum clearance device provided by this invention are as follows:

[0016] 1. Through the linkage design of the support component and the vibration adjustment component, the device can flexibly adjust the tilt angle of the support plate to adapt to the patient's spinal curve and bed posture, and can also generate controllable regular vibration through the motor, cam, and linkage mechanism. The two work together to set the best sputum expectoration position for patients with different conditions and body types, and can effectively loosen the deep sputum in the airway through the adjustable vibration frequency and amplitude, thereby significantly improving the sputum expectoration efficiency and meeting the needs of individualized treatment.

[0017] 2. The fully enclosed medical sponge cover can convert mechanical vibration into a gentle force that is transmitted to the patient's back, reducing the pressure and discomfort caused by direct contact with rigid components and effectively reducing the decrease in patient tolerance caused by postural discomfort; at the same time, the sponge cover can protect the components, preventing external dust and impurities from entering the components and affecting the stability of equipment operation, thereby extending the service life of the device.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 To be continued Figure 7 As shown:

[0030] Example 1:

[0031] This invention provides an intelligent postural vibration sputum clearance device, comprising a support component 1 and a vibration adjustment component 2. The support component 1 includes a support plate 11 (the support plate 11 is designed to correspond to the patient's back support area, is made of medical-grade ABS composite board, and has rounded corners to avoid sharp edges from scratching the patient. At the same time, the board has a certain toughness and load-bearing capacity, which can stably bear the patient's body pressure and transmit vibration force) and a base plate 12 (the base plate 12 is integrally formed from high-strength lightweight alloy material, and is arranged horizontally. Anti-slip rubber can be added to its bottom). The rubber pads not only enhance the stability of the equipment placed on the bed surface, preventing displacement during vibration, but also reduce vibration transmission when the equipment is in contact with the bed surface, thus reducing the impact on the bed. The base plate 12 is set horizontally, and the support plate 11 is set at an angle on top of the base plate 12. The support plate 11 and the base plate 12 are rotatably connected by a hinge seat 13 (the hinge seat 13 is made of stainless steel and has a built-in wear-resistant bearing structure to ensure that the support plate 11 rotates flexibly and smoothly around the hinge point without jamming, and can withstand the wear and tear caused by long-term vibration and load-bearing, extending the service life of the equipment).

[0032] The support component 1 and vibration adjustment component 2 are encased inside the sponge cover 3. The size of the sponge cover 3 is adapted to the support plate 11 and the base plate 12. (The sponge cover 3 uses high-density medical sponge as the core material and is covered with a waterproof and antibacterial fabric. It has good elastic cushioning performance and is easy to clean and disinfect daily, meeting medical hygiene standards. Its size has been precisely calculated to perfectly match the outline of the support plate 11 and the base plate 12. After being encased, it can fit tightly against the surface of each component without any excess wrinkles or gaps.) A control panel 4 is installed on one side of the sponge cover 3 (a mounting groove is reserved on one side of the sponge cover 3). The control panel 4 is embedded in the groove. After installation, the surface of the control panel 4 is basically flush with the surface of the sponge cover 3, which does not affect the overall aesthetics of the equipment and prevents the control panel 4 from being damaged by collisions. The control panel 4 adopts a waterproof touch design, equipped with a high-definition display screen and simple operation buttons. The built-in circuit is electrically connected to the drive components of the support component 1 and the vibration adjustment component 2 through the pre-set wire holes inside the sponge cover 3, which can realize the adjustment of parameters such as the body position angle, vibration intensity, and vibration frequency of the equipment. It is convenient to operate and adapts to the daily usage habits of medical staff.

[0033] Working principle: Before performing sputum clearance, the operator must first place the intelligent postural vibration sputum clearance device stably in a suitable position on the patient's bed to ensure that the device is evenly stressed and placed stably, and to avoid displacement due to vibration during operation; then assist the patient to adjust their posture so that the patient's back naturally rests against the surface of the sponge cover 3 of the device, ensuring that the patient's body fits closely to the sponge cover 3, laying the foundation for comfortable sputum clearance; after the preparation is completed, the operator initiates the coordinated control command of the support component 1 and the vibration adjustment component 2 through the control panel 4 integrated on one side of the device to start the entire sputum clearance process;

[0034] During the position adjustment phase, the support plate 11 in the support assembly 1 can rotate flexibly relative to the base plate 12 around the hinge seat 13. The operator can precisely adjust the tilt angle of the support plate 11 through the control panel 4 according to the patient's physical condition, medical needs, and bed posture. Whether it is a slight tilt when lying flat or a larger tilt angle in a semi-recumbent position, it can achieve precise adaptation and effectively fit the spinal physiological curve and position habits of different patients, avoiding patient resistance due to positional discomfort, while providing the best force angle for vibration sputum drainage.

[0035] After the patient's posture is adjusted, the vibration adjustment component 2 is activated synchronously and generates regular vibration. The vibration force is stably transmitted to the support plate 11 through the internal transmission structure of the component, and then transmitted to the outer sponge cover 3 through the support plate 11, and finally acts on the patient's back. Through this targeted vibration force, the sputum in the patient's lungs and airway can be effectively loosened, the adhesion between the sputum and the airway mucosa can be broken, and the power support for the sputum to be expelled can be provided.

[0036] Throughout the vibration-assisted sputum clearance process, the sponge cover 3 plays a dual crucial role. First, it provides full-coverage protection for the internal support component 1 and vibration adjustment component 2, preventing external dust and impurities from entering the components and affecting the stability of equipment operation, while also preventing loosening or displacement of component parts during vibration. Second, the sponge material has excellent elastic cushioning properties, which can effectively weaken the impact of vibration, transforming the vibration of rigid components into a gentle force transmitted to the patient, reducing the pressure and discomfort caused by direct contact between the patient's skin and the rigid components of the equipment, and significantly improving the comfort of the sputum clearance process. Finally, through the precise coordination and cooperation of body position adjustment and vibration action, a personalized, comfortable, and highly adaptable sputum clearance operation is achieved for the patient, ensuring both sputum clearance effectiveness and patient tolerance.

[0037] Example 2:

[0038] This embodiment is basically the same as the previous embodiment, except that the vibration adjustment component 2 includes two fixing plates 21, which are symmetrically and vertically fixed to the top of the base plate 12. The two fixing plates 21 are set between the support plate 11 and the base plate 12 (the fixing plates 21 are made of high-strength medical alloy plates, which have excellent load-bearing capacity and anti-vibration deformation capacity. The two are symmetrical about the central axis of the base plate 12 and are vertically fixed to the top end face of the base plate 12). A dual-axis motor 22 is provided between the two fixing plates 21. The dual-axis motor 22 is installed on the top of the support plate 11 (the dual-axis motor 22 is a low-noise, high-stability medical-grade dual-axis output motor. Its body is fixed to the bottom end face of the support plate 11 by a shock-absorbing bracket. The shock-absorbing bracket can effectively reduce the vibration noise generated by the motor during operation and prevent the motor vibration from being directly transmitted to the support plate 11, affecting the comfort of sputum suction). Cams 23 are provided on both sides of the output end of the dual-axis motor 22 (the cams 23 are made of wear-resistant alloy steel, and their contours are precisely designed to achieve periodic eccentric power output, providing a power source for subsequent reciprocating vibration).

[0039] A connecting rod 24 is rotatably connected to cam 23 (the edges of cam 23 are rotatably connected to connecting rod 24 via bearings; the bearings reduce the relative friction between cam 23 and connecting rod 24; connecting rod 24 is made of high-strength alloy steel). A connecting rod 25 is rotatably connected to connecting rod 24. The other end of connecting rod 24 is rotatably mounted on fixed plate 21 via fixed shaft 26 (fixed shaft 26 is made of stainless steel, and both ends are fixed to fixed plate 21 by retaining springs to ensure that connecting rod 24 can swing flexibly around fixed shaft 26 without axial displacement). (Move), Link 2 25 is vertically mounted on Link 1 24, and Link 2 25 is positioned in the middle of Link 1 24. A telescopic component 27 is installed at the top of Link 2 25 (the telescopic component 27 is an electric telescopic rod, featuring precise and controllable stroke and smooth extension and retraction; the extension stroke can be adjusted via the control panel 4 to adapt to the body position angle requirements). A horizontal plate 28 is fixedly connected to the fixed plate 21, and the horizontal plate 28 is vertically mounted on the fixed plate 21, positioned near the top of the fixed plate 21 (the horizontal plate 28 is also made of medical alloy material, vertically welded and secured with bolts). The device is reinforced on the fixed plate 21, with its installation position close to the top area of ​​the fixed plate 21, and the horizontal plates 28 on the two fixed plates 21 are horizontally aligned. A mounting base 29 is fixedly connected to the horizontal plate 28. The telescopic end of the telescopic component 27 is rotatably connected to the connecting rod 25. The telescopic end of the telescopic component 27 is slidably embedded inside the mounting base 29 (the mounting base 29 has a sliding groove adapted to the telescopic component 27, and the inner wall of the groove is provided with a wear-resistant bushing to reduce sliding friction; the horizontal plate 28 and the mounting base 29 provide guidance and support for the telescopic component 27). The telescopic component 27 is fixed... A vertical rod 210 is fixedly connected, and a hinge seat 211 is rotatably connected to the top of the vertical rod 210 (the vertical rod 210 is an integrally formed alloy rod, and the top is rotatably connected to the support plate 11 through the hinge seat 211). The hinge seat 211 is fixed on the support plate 11. Both output ends of the dual-axis motor 22 are connected to eccentric wheels 212, and both cams 23 are fixed on the eccentric wheels 212 (the eccentric wheels 212 are made of wear-resistant alloy steel, and their contours are precisely designed to achieve periodic eccentric power output, providing a power source for the subsequent reciprocating vibration of the cams 23).

[0040] Working principle: The operator first issues an adjustment command through the control panel 4 to precisely set the extension stroke of the telescopic component 27. By changing the extension length of the telescopic component 27, the vertical rod 210 is driven to move up and down. Then, the hinge seat 211 at the top of the vertical rod 210 pulls or supports the support plate 11, causing the support plate 11 to rotate relative to the base plate 12 around the hinge seat 13. Finally, the tilt angle of the support plate 11 can be flexibly adjusted. After the angle is adjusted, the device can adapt to the positional needs of patients with different body types and conditions. For example, it can adapt to slight positional adjustments for elderly or weak patients, or to specific positional fixation for postoperative patients.

[0041] After the body position is adjusted and fixed, the operator starts the dual-axis motor 22 through the control panel 4. The dual-axis motor 22 outputs power stably, driving the output ends on both sides to rotate synchronously, thereby driving the eccentric wheel 212 fixed at the output end to make uniform circular motion. Since the eccentric wheel 212 is a non-uniform diameter structure and is mounted on the cam 23, the cam 23 will generate a periodic eccentric force during rotation. This force is transmitted to the connecting rod 24 that is rotatably connected to it, pushing the connecting rod 24 to make reciprocating swing motion around the fixed shaft 26 fixed on the fixed plate 21.

[0042] During the reciprocating swing of link 24, it drives link 25, which is vertically connected at its middle position, to move in sync. This causes link 25 to undergo regular angular changes and displacements as link 24 swings. At this time, telescopic component 27, which is rotatably connected to link 25, moves in reciprocating motion along the sliding trajectory inside mounting base 29 under the guidance of mounting base 29 on horizontal plate 28. The telescopic motion of telescopic component 27 and the linkage motion of link 25 are coordinated and adapted to each other to ensure the stability and smoothness of power transmission. Simultaneously, vertical rod 210, which is fixedly connected to telescopic component 27, moves in reciprocating motion in the vertical direction under the drive of telescopic component 27.

[0043] The top of the vertical rod 210 is fixedly connected to the support plate 11 via the hinge seat 211, which smoothly transmits the reciprocating lifting power to the support plate 11, pushing the support plate 11 to periodically reciprocate around the hinge seat 13 relative to the bottom plate 12, thereby generating a regular vibration force on the support plate 11; this vibration force is buffered and softened by the sponge cover 3 and then transmitted to the patient's back, acting on the lungs and corresponding airway areas, effectively loosening sputum and promoting the discharge of sputum into the airway, achieving efficient sputum expectoration;

[0044] To meet the personalized sputum clearance needs of different patients, operators can adjust the rotation speed of the dual-axis motor 22 in real time through the control panel 4, thereby changing the rotation speed of the cam 23 and ultimately adjusting the vibration frequency of the support plate 11. At the same time, the swing amplitude and tilt angle of the support plate 11 can be further fine-tuned by adjusting the extension stroke of the telescopic component 27. Through multi-dimensional precise control of vibration frequency, swing amplitude, and body position angle, the sputum clearance needs of patients of different ages and with different disease severity can be adapted. For example, for patients with thick sputum, the vibration frequency can be increased and the swing amplitude can be increased, while for weak patients, the vibration intensity can be reduced and the body position angle can be optimized, achieving safe, efficient, and personalized sputum clearance treatment.

[0045] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
