Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a vibrating expectoration device for good limb positioning and a working method thereof. Background Art

[0002] Critically ill patients undergoing rehabilitation often experience symptoms such as impaired consciousness, quadriplegia, and tracheostomy, requiring prolonged bed rest. Proper supine and limb positioning can maintain good blood circulation and prevent complications. The supine position can easily lead to pneumonia, atelectasis, pressure ulcers, and reflux aspiration. The lateral position promotes dorsal alveolar re-expansion, improves oxygenation, reduces aspiration of oropharyngeal secretions, reduces the risk of tongue prolapse, and improves ventilation. Therefore, proper positioning is crucial. Early implementation of proper limb positioning can also protect joints and surrounding soft tissues. In later stages of rehabilitation, passive movement can reduce pain and enable patients to transition more quickly to rehabilitation. Current patient positioning management typically utilizes pillows and cushions to support the legs and back in the lateral position. However, this often leads to significant slipping, falling, or flattening, requiring constant monitoring and repositioning by medical staff. Furthermore, medical staff must frequently perform manual back tapping to expel phlegm and improve breathing. These back tapping procedures often occur at night, resulting in a heavy workload and a lack of rest for medical staff. Existing expectoration devices are mostly vest-type and handheld. The vest-type expectoration device is inconvenient to put on and take off for seriously ill patients, and is also uncomfortable to wear. The handheld device requires medical staff to operate it by hand, which cannot greatly reduce the workload of medical staff.

[0003] Therefore, a new type of device is needed that can simultaneously achieve optimal limb positioning and vibration expectoration functions, freeing medical staff from heavy work and solving problems existing in the existing technology. Summary of the Invention

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0059] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0060] Unless otherwise specified, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0061] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

[0073] Working principle of the present invention:

[0074] Long-term bed rest with incorrect posture can lead to many diseases, such as pneumonia, atelectasis, pressure sores, reflux aspiration, etc. The side-lying position can help disperse body pressure, reduce these risks, and promote functional recovery. The side-lying position can not only help patients prevent complications, but also lay a solid foundation for subsequent rehabilitation training. The side-lying position combined with back tapping can promote the flow of sputum to the large airways, reduce the aspiration of oropharyngeal secretions, and achieve the purpose of improving breathing. This good limb positioning vibration expectoration device can not only adjust the limb position, but also automatically vibrate to expectorate, greatly reducing the workload of medical staff.

[0075] The left leg support mechanism 2 utilizes a reduction motor-driven connecting rod mechanism. Through rational geometric design and physical constraints, the motion range of connecting rod 1 2.1 is reliably limited. This allows for rotation of the left leg support plate 2 1.17 from a horizontal to a vertical position while ensuring that the rotation range of the left leg support plate 1.17 does not exceed 90°, thus avoiding the risk of patient entrapment. Similarly, the right leg support mechanism 7 also reliably limits the motion range of connecting rod 4 7.1, allowing for rotation of the right leg support plate 2 1.27 from a horizontal to a vertical position while ensuring that the rotation range of the right leg support plate 1.27 does not exceed 90°, thus avoiding the risk of patient entrapment.

[0076] The right back support mechanism 4 similarly utilizes a reduction motor-driven connecting rod mechanism. Through reasonable geometric design and physical constraints, it reliably limits the range of motion of connecting rod 2 4.1, thereby enabling the right back support panel 1.5 to rotate from a horizontal to a vertical position while ensuring that the right back support panel 1.5 does not rotate beyond 90°, thus avoiding the risk of patient pinching. Similarly, the left back support mechanism 6 reliably limits the range of motion of connecting rod 3 6.1, thereby enabling the left back support panel 1.1 to rotate from a horizontal to a vertical position while ensuring that the left back support panel 1.1 does not rotate beyond 90°, thus avoiding the risk of patient pinching.

[0077] The right vibration mechanism 3 uses a reduction motor to drive the main shaft 1 3.6 to rotate. The main shaft 1 3.6 rotates together with the cam 1 3.5 and the cam 2 3.7. The cam 1 3.5 and the cam 2 3.7 push the vibration hammer 1 3.15 forward to reach the end of its travel. As the cam 1 3.5 and the cam 2 3.7 continue to rotate, the spring 1 3.13 and the spring 2 3.17 push the vibration hammer 1 3.15 in the opposite direction, completing the vibration back-knocking and expectoration action. Similarly, the left vibration mechanism 5 uses a reduction motor to drive the main shaft 2 5.6 to rotate. The main shaft 2 5.6 rotates together with the cam 3 5.5 and the cam 4 5.7. The cam 3 5.5 and the cam 4 5.7 push the vibration hammer 2 5.15 forward to reach the end of its travel. As the cam 3 5.5 and the cam 4 5.7 continue to rotate, the spring 3 5.13 and the spring 4 5.17 push the vibration hammer 2 5.15 in the opposite direction, completing the vibration back-knocking and expectoration action.

[0078] When the left back support 1.1, right back support 1.5, left leg support 1 1.12, left leg support 2 1.17, right leg support 1 1.25, and right leg support 2 1.27 of the base 1 are simultaneously flattened, the patient can be placed in the supine position. When the right back support 1.5, left leg support 1 1.12, and left leg support 2 1.17 are simultaneously raised, the patient can be placed in the right side decubitus position. Similarly, when the left back support 1.1, right leg support 1 1.25, and right leg support 2 1.27 are simultaneously raised, the patient can be placed in the left side decubitus position.

When expectoration is required, the motor 1 3.20 of the right vibration mechanism 3 is started, and the motor 1 3.20 drives the main shaft 1 3.6, the cam 1 3.5, and the cam 2 3.7 to rotate together, and the cam 1 3.5 and the cam 2 3.7 together push the vibration hammer 1 3.15 to move. Under the repeated and continuous action of the cam 1 3.5, the cam 2 3.7, the spring 1 3.13, and the spring 2 3.17, the vibration hammer 1 3.15 continuously vibrates and knocks on the back to expectorate.

[0081] When using the left side decubitus expectoration function of the good limb positioning vibration expectoration device, first the patient is in a supine position, and the drive motor three 6.5 of the left back support mechanism 6 is started. The drive motor three 6.5 drives the drive rod three 6.3 to make a circular motion, and the drive rod three 6.3 drives the connecting rod three 6.1 to move, and the connecting rod three 6.1 drives the left back support plate 1.1 to rotate around the upper left pin shaft one 1.2 and the upper left pin shaft two 1.6, and the patient leans his back against the left back support plate 1.1 until it is adjusted to a comfortable position, and the drive motor three 6.5 brakes to keep the left back support plate 1.1 in position, and at the same time, the left positioning pin 1.34 is inserted into the positioning hole to fix the left back support plate 1.1, completing the good limb positioning of the trunk. Start the driving motor four 7.5 of the right leg support mechanism 7, and the driving motor four 7.5 drives the driving rod four 7.3 to perform circular motion, and the driving rod four 7.3 drives the connecting rod four 7.1 to move, and the connecting rod four 7.1 pushes the right leg support plate two 1.27 to rotate around the right lower pin shaft two 1.24 and the right lower pin shaft three 1.26, and the right leg support plate two 1.27 drives the right leg support plate one 1.25 to move, and the right leg support plate one 1.25 drives the right support rod one 1.20 and the right support rod two 1.29 to rotate around the right support rod pin shaft two 1.22 and the right support rod pin shaft four 1.31 respectively, until the right leg support plate one 1.25 moves to a comfortable height, and the driving motor four 7.5 brakes to keep the right leg support plate one 1.25 in place, and the patient's right leg is placed on the right leg support plate one 1.25 with the hip extended and the knee slightly bent to complete the good limb position of the leg. When expectoration is required, the motor 2 5.20 of the left vibration mechanism 5 is started, and the motor 2 5.20 drives the main shaft 2 5.6, the cam 3 5.5, and the cam 4 5.7 to rotate together, and the cam 3 5.5 and the cam 4 5.7 together push the vibration hammer 2 5.15 to move. Under the repeated action of the cam 3 5.5, the cam 4 5.7, the spring 3 5.13, and the spring 4 5.17, the continuous vibration of the vibration hammer 2 5.15 to knock on the back and expectorate is completed.
