Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and in particular relates to an adjustable support backplate suitable for vibration sputum drainage. Background Technology

[0002] In clinical practice, vibration-assisted expectoration is an important adjunct method to help patients with respiratory diseases expel sputum, especially suitable for patients who are bedridden for extended periods, have weak coughs, or have thick sputum. Currently, the most widely used vibration-assisted expectoration method in clinical practice relies on healthcare workers holding a vibrator and moving it along a specific path on the patient's back. The vibration loosens the sputum and promotes its movement into the large airways, making it easier for the patient to cough up. However, this traditional handheld method has several limitations:

[0003] 1. Increased workload for medical staff: Medical staff need to operate the vibrator by hand throughout the process. In scenarios that require multiple sputum removals or a large number of patients, this will significantly increase the physical exertion and workload of medical staff. Especially when medical resources are scarce, it may affect the efficiency and timeliness of sputum removal procedures.

[0004] 2. Poor operational consistency: Due to reliance on manual operation, parameters such as the force applied, movement speed, and vibration frequency of the vibrator are difficult to maintain stability. Different medical staff have different operating habits, and even the same medical staff may experience fluctuations in operating parameters due to fatigue or other factors during prolonged operation, thus affecting the stability of sputum expectoration.

[0005] 3. Limited expectoration effect: When operating by hand, the fit between the vibrator and the patient's back is easily affected by the operating technique. If the fit is not tight, it will reduce the transmission efficiency of vibration energy. At the same time, it is difficult to ensure the standardization of the movement path, which may miss some lung segments, resulting in incomplete expectoration.

[0006] 4. Poor patient experience: The instability of manual operation may cause the intensity of vibration felt by the patient to fluctuate, increasing discomfort; in addition, for patients who need long-term sputum expectoration, frequent manual operation will also reduce their cooperation. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an adjustable support backplate suitable for vibration-assisted sputum drainage, which effectively solves the problems of poor operational consistency, limited sputum drainage effect, and increased workload for medical staff caused by manual handheld vibration-assisted sputum drainage.

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a vibration sputum suction machine and two symmetrical support plates. The support plates are connected by an angle adjustment mechanism and their tilt angles can be adjusted relative to each other. The inner surface of the support plate is a biomimetic structure conforming to the curve of the human back. Elastic straps are fixedly connected to the edges of the support plates to secure the device to the patient's back. Each support plate is embedded with multiple longitudinally evenly distributed vibrators. The vibrators on the two support plates are symmetrically distributed. The vibration sputum suction machine has a built-in control unit configured to control multiple vibrators on the same support plate to vibrate sequentially from bottom to top, and the start interval between adjacent vibrators is adjustable.

[0009] Preferably, each support plate has multiple equal and symmetrical fasteners fixedly connected to its back side, and each pair of symmetrical fasteners is fixedly connected to a tension band.

[0010] Preferably, the tensioning band and the fixing member are detachably connected by a snap-fit ​​structure.

[0011] Preferably, the elastic strap surface is provided with a Velcro or snap fastener structure, and the tensioning band is an elastic rubber band or webbing.

[0012] Preferably, the inner surface of the support plate is covered with a flexible silicone pad, and the vibrator is an eccentric wheel motor or a linear motor.

[0013] Preferably, the angle adjustment mechanism includes a connecting block disposed on the back of the support plate and a positioning frame that cooperates with the connecting block. The positioning frame is configured to be adjustable in terms of up and down position, left and right position, and tilt angle. Two left and right symmetrical limit pins are fixedly connected to the positioning frame. The connecting block has a limit groove that cooperates with the limit pins.

[0014] Preferably, it further includes a support frame, which includes a base connector, a lifting rod, a swing frame, and a positioning frame. One end of the lifting rod is connected to the base connector and is configured to be height-adjustable. The swing frame is connected to the other end of the lifting rod via a rotary joint and is configured to tilt forward or backward to adjust the angle, and the adjusted angle is fixed by a locking device. The positioning frame is rotatably connected to the end of the swing frame away from the lifting rod and is configured to have an adjustable tilt angle.

[0015] Preferably, the control unit is electrically connected to the vibrator via a wire; the control unit includes:

[0016] A microprocessor is used to execute a preset vibration control program.

[0017] The sequential control module, electrically connected to the microprocessor, is configured to generate trigger signals that activate the vibrators sequentially from bottom to top.

[0018] The time interval adjustment module is electrically connected to the sequence control module and is configured to set the interval time between the start of adjacent vibrators;

[0019] The vibration frequency adjustment module is electrically connected to the vibrator and is configured to adjust the vibration frequency of each vibrator.

[0020] The timing module can be configured to set the total vibration duration or the number of cycles.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. Reduce the workload of medical staff: This utility model eliminates the need for medical staff to operate the vibrator by hand. It achieves automated vibration sputum clearance through a support plate assembly that can be fixed to the patient's back, reducing the physical exertion and continuous workload of medical staff. Especially in the care of a large number of patients or in the case of high-frequency sputum clearance, it can significantly improve work efficiency and alleviate the pressure of medical resource shortage.

[0023] 2. Improve the stability and consistency of sputum expectoration: With the precise control of the vibrator by the control unit, multiple vibrators on the same support plate vibrate in a cyclical manner from bottom to top. The start interval, vibration frequency, and total duration of adjacent vibrators can all be adjusted to avoid the problems of uneven force and inconsistent movement speed in manual operation. This ensures that the vibration effect is uniform and regular, thereby guaranteeing the stability and reliability of the sputum expectoration effect and improving the efficiency of sputum expectoration.

[0024] 3. Ensuring Safety and Comfort: The inner surface of the support plate adopts a biomimetic structure that conforms to the curve of the human back and is covered with a flexible silicone layer, allowing it to fit closely to the patient's back while avoiding discomfort from hard contact. Vibrators are distributed on both sides of the spine, and together with the positioning function of the support frame, effectively prevent the support plate from shifting to the back of the spine and causing injury. At the same time, the design of elastic straps and tension bands ensures both effective fixation and adaptability to different patient body shapes, improving comfort and safety during use.

[0025] 4. Enhanced applicability and flexibility of the device: The multi-dimensional adjustment functions of the angle adjustment mechanism and support frame (height, forward / backward tilt angle, tilt angle, etc.) can adapt to different patient positions (sitting, lying, etc.) and back curves to meet the needs of different patients; the detachable connection between the tension band and the fixing parts, and the Velcro / fastener design of the elastic straps make the installation, disassembly and adjustment of the device more convenient.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0034] Reference Figure 1-5 As shown, this utility model discloses an adjustable support backplate suitable for vibration-assisted sputum drainage. It mainly consists of a vibration-assisted sputum drainage machine 1, a support plate assembly, an angle adjustment mechanism, a support frame, a tensioning mechanism, and a control unit. These components work together to achieve the vibration-assisted sputum drainage function. The specific structure is as follows:

[0035] The support plate body comprises two symmetrical support plates 2. The inner surface of the support plate 2 has a biomimetic structure that conforms to the curve of the human back, allowing it to fit closely to the patient's back and improve comfort. A flexible silicone pad is placed on the inner surface to further enhance the patient's tactile experience and prevent pressure damage to the skin from a hard surface. Each support plate 2 is embedded with multiple longitudinally evenly distributed vibrators 4, symmetrically distributed on both support plates 2. The vibrators 4 can be either eccentric wheel motors or linear motors, producing effective vibration to power sputum expectoration.

[0036] Each support plate 2 has an elastic strap 3 fixedly connected to its edge. The surface of the elastic strap 3 has a Velcro or snap fastener structure for easy fixation of the device to the patient's back. Each support plate 2 has multiple equal and symmetrical fasteners 5 fixedly connected to its back. Each pair of symmetrical fasteners 5 is fixedly connected to a tension band 6, which is an elastic rubber band or webbing. The tension band 6 is detachably connected to the fasteners 5 via a snap-fit ​​structure, which facilitates installation and removal and enhances the fit between the support plate and the patient's back.

[0037] Depend on Figure 2 As shown, the two support plates 2 can be directly fixed to the patient's back using elastic straps 3. Two sets of vibrators 4 are placed on the left and right sides of the spine. Then, the vibration expectoration machine 1 is activated, causing the vibrators 4 to vibrate according to a set program to assist the patient in expectorating sputum. However, simply fixing the support plates 2 with the elastic straps 3 not only fails to maintain a suitable expectoration position for the patient, but also, with prolonged vibration, the support plates 2 are prone to displacement. If they move to the back of the spine, it may cause some damage. Therefore, a support frame is needed to help position the support plates 2, maintain the patient's position, and prevent displacement. Details are as follows:

[0038] The angle adjustment mechanism includes a connecting block 7 disposed on the back of the support plate 2, and a positioning frame 8 that cooperates with the connecting block 7. The positioning frame 8 is configured to be adjustable in vertical position, horizontal position, and its own tilt angle. Two left-right symmetrical limit pins 9 are fixedly connected to the positioning frame 8. The connecting block 7 has a limit groove 10 that cooperates with the limit pins 9. Through the cooperation of the limit pins 9 and the limit groove 10, the connection between the support plate 2 and the positioning frame 8 and the angle are fixed.

[0039] The support frame includes a base connector 11, a lifting rod 12, a swing frame 13, and a positioning frame 8. One end of the lifting rod 12 is connected to the base connector 11 and is height-adjustable, allowing the height of the device to be adjusted according to the patient's needs. The swing frame 13 is connected to the other end of the lifting rod 12 via a rotating joint and is configured to tilt forward or backward to adjust the angle, and the adjusted angle is fixed by a locking device to accommodate different patient postures. The positioning frame 8 is rotatably connected to the end of the swing frame 13 away from the lifting rod 12 and is configured to adjust the tilt angle, further optimizing the position of the support plate 2 so that the support plate 2 fits the patient's back better.

[0040] For example, such as Figure 1 , Figure 3As shown, the base connector 11 is fixedly connected to the chair so that the support plate 2 serves as the chair's backrest. The patient sits on the chair with both arms on the armrests, and the body is upright or bent forward. The two support plates 2 are positioned with the patient's back as the reference point. The vertical position, front-back position, and angle of the support frame are adjusted so that the support plates 2 fit the patient's back. At this time, the positions of the two support plates 2 are fixed by the elastic strap 3, and then the vertical position, front-back position, and angle of the support frame are locked by the locking device to keep the patient in the expectoration position.

[0041] The control unit is built into the vibration suction machine 1 and is electrically connected to the vibrator 4 via wire 14. It is used to control the working state of the vibrator 4. The control unit includes a microprocessor, a sequence control module, a time interval adjustment module, a vibration frequency adjustment module, and a timing module. The microprocessor is used to execute a preset vibration control program; the sequence control module is electrically connected to the microprocessor and is configured to generate trigger signals to activate the vibrators 4 sequentially from bottom to top; the time interval adjustment module is electrically connected to the sequence control module and is configured to set the interval between the activation of adjacent vibrators 4; the vibration frequency adjustment module is electrically connected to the vibrator 4 and is configured to adjust the vibration frequency of each vibrator 4; the timing module is configured to set the total vibration duration or the number of cycles.

[0042] The vibration control program includes the following steps: initializing all vibrators 4 to standby state; starting from the bottom vibrator 4, triggering the vibrators 4 to work sequentially at set time intervals; when the last vibrator 4 is triggered, returning to the first step and repeating the process; during vibration, adjusting the vibration intensity in real time through the vibration frequency adjustment module.

[0043] The usage process of this utility model is as follows:

[0044] First, check whether each component of the device is intact, whether the tensioning band 6 is securely connected to the fixing part 5 through the buckle structure, whether the Velcro or snap structure of the elastic strap 3 can be used normally, and whether the connection of the wire 14 is stable.

[0045] Next, position the patient comfortably, either sitting or lying down, depending on their condition. Place the inner surface of the support plate 2 against the patient's back, and secure the device to the patient's back using the Velcro or snap fasteners on the surface of the elastic strap 3, ensuring a tight fit and patient comfort without excessive pressure.

[0046] Based on the patient's back curve and sputum expectoration needs, the relative tilt angle of the two support plates 2 is adjusted by the angle adjustment structure. At the same time, the height of the support frame is adjusted by the lifting rod 12, the forward or backward tilt angle of the device is adjusted by the swing frame 13, and the tilt angle is adjusted by the positioning frame 8 to place the support plate 2 in the optimal position.

[0047] Next, adjust the tension of the tension band 6 as needed to ensure that the support plate 2 fits the patient's back better. If some tension bands 6 are not needed, they can be removed through the buckle structure.

[0048] Finally, the control unit of the vibration sputum suction machine 1 is operated to set the interval between the start of adjacent vibrators 4 on the same support plate 2 through the time interval adjustment module; the vibration frequency of each vibrator 4 is adjusted through the vibration frequency adjustment module; and the total vibration duration or number of cycles is set through the timing module.

[0049] After the parameters are set, the device is started. The microprocessor of the control unit executes the preset vibration control program. The sequential control module generates trigger signals to activate the vibrators 4 sequentially from bottom to top, so that multiple vibrators 4 on the same support plate 2 vibrate in a cyclic manner from bottom to top, and the vibration sputum removal process begins.

[0050] During the vibration-assisted sputum clearance process, nebulization can be used to dilute the sputum. Close attention should be paid to the patient's reaction. If the patient feels uncomfortable, the device can be stopped at any time and the parameters or device position can be adjusted.

[0051] The device will automatically stop working when the total vibration duration set by the timing module ends or the number of cycles is completed. Turn off the device power, untie the elastic strap 3, remove the device from the patient's back, and clean and tidy the device for future use.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
