[0049] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0050] As Figures 1-8 shown, a mechanical auxiliary bed for postural drainage of patients in the department of respiratory medicine according to the present invention includes a backboard 1, a buttock and thigh board 2, a lower limb board 3 and a bed body 4, and further includes:

[0051] A postural adjustment mechanism 5 and a back patting and sputum drainage mechanism 6; wherein:

[0052] The postural adjustment mechanism 5 includes a lifting assembly 51 provided between the backboard 1 and the buttock and thigh board 2, between the buttock and thigh board 2 and the lower limb board 3 and at its lower part. The lifting assembly 51 is used to realize the angle adjustment between the backboard 1, the buttock and thigh board 2, and the lower limb board 3 and the lifting changes of the overall height, etc., so as to meet the position requirements of various parts of the body of the patient during different postural drainage. A lateral tilting assembly 52 is opened and provided at the lower part of the backboard 1 and the buttock and thigh board 2. The lateral tilting assembly 52 can tilt a part of the backboard 1 and the buttock and thigh board 2 in the lateral direction, facilitating the adjustment of the patient's left and right lateral tilting postures, and a pitching assembly 53 provided at the four corners of the lower end of the bed body 4. The pitching assembly 53 can adjust the overall pitching state of the bed body 4, so that one end of the head or foot of the bed body 4 is lifted or lowered, realizing the postures of head high and foot low or head low and foot high;

[0053] The back patting and sputum drainage mechanism 6 includes a vibration striking assembly 61 provided inside the backboard 1 and a sputum drainage assembly 62 provided on the side wall of the bed body 4. The vibration striking assembly 61 can pat the back of the patient to help loosen the respiratory tract secretions for easy discharge; the sputum drainage assembly 62 is used to collect the sputum discharged by the patient for centralized treatment to keep the environment clean.

[0054] As Figures 1-7As shown, in this embodiment, the lifting component 51 includes a rotating shaft a5101 and a rotating shaft b5102 provided between the backboard 1 and the hip and leg board 2, and between the hip and leg board 2 and the lower limb board 3, respectively. The rotating shaft a5101 and the rotating shaft b5102 are key structures for realizing relative rotation between the backboard 1 and the hip and leg board 2, and between the hip and leg board 2 and the lower limb board 3, and provide a rotating fulcrum for adjusting the angle between each board. The rotating shaft a5101 is provided at the connection of the lower surface, so that when the backboard 1 and the hip and leg board 2 rotate around it, the patient's upper body can be lifted up smoothly. The rotating shaft b5102 is provided at the connection of the upper surface, so that the hip and leg board 2 and the lower limb board can be lifted up smoothly. The rotation between the limb boards 3 fits the changes in the body positions of the human legs and buttocks. For example, when adjusting the body positions such as the semi-sitting and lying positions, the lower limb board 3 can be reasonably rotated relative to the hip and leg board 2. The front ends of the two side walls of the hip and leg board 2 are provided with fixed shafts 5103. The fixed shafts 5103 ensure that when the body position is adjusted, the end of the hip and leg board 2 close to the buttocks remains in place. The rear ends of the two side walls of the lower limb board 3 are provided with rollers 5104. The rollers 5104 can roll in the corresponding grooves of the bed body 4. When the hip and leg board 2 and the lower limb board 3 are lifted and lowered, the lower limb board 3 and the hip and leg board 2 can be lifted smoothly and always stay in the corresponding positions, thereby ensuring their stability.

[0055] The front and rear sides of the lower surfaces of the backboard 1 and the hip and leg board 2 are respectively provided with support rods 5105, which support the backboard 1 and the hip and leg board 2 to ensure that each board has the corresponding load-bearing capacity under different body positions when lifted or lowered, so that the patient can lie on it more stably. A clamping ring a5106 is provided at the lower end of the support rod 5105, and the clamping ring a5106 is used to clamp the extension rod a5107. It is a structure connecting the support rod 5105 and the extension rod a5107, which can realize the detachability or relative fixation of the two. The extension rod a5107 is clamped in the clamping ring a5106, and the other end of the extension rod a5107 is provided with an air pump a5108. The extension rod a5107 can extend the length of the support rod 5105, and cooperate with the action of the air pump a5108 to realize the lifting and lowering of the backboard 1 and the hip and leg board 2, and the height position of each board is adjusted by changing its own length;

[0056] On the upper surface of the bed body 4, a board groove a5109 and a board groove b5110 are longitudinally formed in sequence. The board groove a5109 and the board groove b5110 are groove bodies for accommodating structures such as the back board 1, the hip and leg board 2, and the lower limb board 3, providing space for the installation, movement, and body position adjustment of each board. At positions corresponding to the fixed shaft 5103 and the roller 5104 on both side walls of the board groove a5109, a fixed groove 5111 and a rolling groove 5112 are respectively formed horizontally. The fixed groove 5111 is connected to the fixed shaft 5103 in a clamping manner to limit the front-back displacement of the hip and leg board 2 and ensure the stability of the hip and leg board 2. The rolling groove 5112 allows the roller 5104 on the lower limb board 3 to roll therein, providing a track for the rotation and movement of the lower limb board 3. At a position corresponding to the support rod 5105 in the board groove b5110, a support groove 5113 is correspondingly formed. The support groove 5113 is used to accommodate the support rod 5105, enabling the support rod 5105 to move and adjust accordingly within the groove along with the actions of the back board 1 and the hip and leg board 2. In the middle of the support groove 5113, an extension groove a5114 and an air pump groove a5115 are respectively formed at positions corresponding to the extension rod a5107 and the air pump a5108. The extension groove a5114 provides space for the telescopic movement of the extension rod a5107, ensuring that the extension rod a5107 will not be obstructed by the structure of the bed body 4 when adjusting its length. The air pump groove a5115 is used to place the air pump a5108, fix and protect the air pump a5108, and at the same time enable the pipelines of the air pump a5108 to be reasonably arranged.

[0057] As Figure 3 , 5 shown, in this embodiment, the tilting assembly 52 includes tilting grooves 521 respectively formed longitudinally through both sides of the upper surfaces of the back board 1 and the hip and leg board 2. The tilting grooves 521 are spaces for the installation and movement of the tilting plates 522, allowing the tilting plates 522 to perform tilting rotation within the grooves to achieve the tilting function. The tilting plates 522 are arranged in the tilting grooves 521 and are movably connected thereto through a rotating shaft c523. The rotating shaft c523 is the rotation fulcrum between the tilting plates 522 and the back board 1 and the hip and leg board 2, enabling the tilting plates 522 to rotate laterally around it. Clamping rings b524 are respectively provided on the outer sides of the lower surfaces of the tilting plates 522. The clamping rings b524 are used to connect the extension rods b525. Similar to the clamping ring a5106, they are structures for connecting the tilting plates 522 and the extension rods b525, facilitating the assembly and adjustment of the tilting actions of the tilting plates 522. The extension rods b525 are clamped within the clamping rings b524. Air pumps b526 are respectively provided at the other ends of the extension rods b525. The extension rods b525 are telescopic. In cooperation with the actions of the air pumps b526, the tilting angles of the tilting plates 522 are controlled. By changing the self-length of the extension rods b525, the positions of the tilting plates 522 are adjusted, thereby enabling the back board 1 or the hip and leg board 2 to achieve different degrees of tilting;

[0058] At positions corresponding to the extension rod b525 and the air pump b526, the board groove b5110 is provided with an extension groove b527 and an air pump groove b528. The extension groove b527 provides a moving space for the telescopic movement of the extension rod b525, and the air pump groove b528 is used to place and fix the air pump b526. Meanwhile, it facilitates the pipeline layout and ensures the stable operation of the air pump b526.

[0059] As Figure 4 shown, in this embodiment, the pitching assembly 53 includes air pump grooves c531 penetrating through the four corners of the lower surface of the bed body 4. The air pump grooves c531 are used to install the air pump c532, providing a placement space and a fixed position for the air pump c532. The air pump c532 is fixedly installed in the air pump groove c531. The air pump c532 is the power source for controlling the telescopic movement of the telescopic support rod 5335105. By inflating or deflating, the length of the telescopic support rod 5335105 is changed, thereby adjusting the height of the four corners of the bed body 4. The lower end of the air pump c532 is provided with a telescopic support rod 5335105, and the other end of the telescopic support rod 5335105 is connected to the foot pad 534. The foot pad 534 increases the contact area between the telescopic support rod 5335105 and the ground, making the placement of the bed body 4 more stable. At the same time, it can play a certain buffering role to avoid excessive wear on the ground caused by the adjustment of the height of the bed body 4.

[0060] As Figure 3 、 5 shown, in this embodiment, the percussion assembly 61 includes a back - patting groove 611 opened at the center of the upper surface of the back plate 1. The back - patting groove 611 is the installation space for each structure in the percussion assembly 61. The inner bottom wall of the back - patting groove 611 is provided with an air pump d612. The air pump d612 provides power for the telescopic movement of the telescopic rod 613. By controlling the inflation and deflation of the air pump d612, the telescopic rod 613 is driven to move up and down, thereby realizing the back - patting action of the back - patting pad 614 on the patient's back. The upper surface of the air pump d612 is provided with a telescopic rod 613, and the upper end of the telescopic rod 613 is connected to the back - patting pad 614. A pressure - sensing pad 615 is provided at the center of the back - patting pad 614. The pressure - sensing pad 615 can detect the back - patting pressure of the back - patting pad 614 on the patient's back and whether the back - patting pad 614 is in contact with the patient's back, and convert the pressure signal into an electrical signal and feedback it to the control system, so as to realize the precise control of the back - patting strength;

[0061] A support ring 616 is provided on the peripheral side wall of the back - patting groove 611. The support ring 616 plays a supporting role to prevent patients in a lying - flat state from overly squeezing the back - patting pad 614 and the air pump d612. The height of the support ring 616 is slightly higher than the height of the back - patting pad 614 and slightly lower than the height of the back - patting groove 611. Such a height setting not only ensures that the back - patting pad 614 can move upward a certain distance during patting to achieve effective patting, but also enables the back - patting pad 614 to fall back below the upper surface of the support ring 616 after patting, playing a certain protective and supporting role. A flexible support pad 617 is provided at the opening of the back - patting groove 611. The flexible support pad 617 has a soft characteristic. When the patient's back lies on the backboard 1, it can buffer and support the patient's back, improving the patient's comfort and also protecting the edge structure of the back - patting groove 611 to a certain extent.

[0062] As Figure 1 、 8 shown, in this embodiment, the sputum - discharging assembly 62 includes a fixed ring 621 fixedly installed at the front end of the side wall of the bed body 4. The fixed ring 621 is used to place and fix the sputum - discharging face mask 627, enabling the sputum - discharging face mask 627 to be stably sleeved on it, which is convenient for patients to use and access. A sputum - collecting box 622 is provided below the fixed ring 621. The sputum - collecting box 622 is a container for collecting the sputum discharged by the patient, collecting the sputum centrally for subsequent processing to keep the ward environment clean. The inside of the sputum - collecting box 622 is hollow, and a sputum - discharging pipe 623 penetrates through the upper surface. The sputum - discharging pipe 623 is the channel for sputum to enter the sputum - collecting box 622 from the sputum - discharging face mask 627, guiding the sputum discharged by the patient into the sputum - collecting box 622. An air purifier 624 is provided on the inner top wall. The air purifier 624 can purify the air in the sputum - collecting box 622, removing the odor emitted by the sputum and possible bacteria, etc., to prevent the air in the sputum - collecting box 622 from polluting the ward environment. A sputum - discharging box 625 is provided on the inner bottom wall. The sputum box is used to collect sputum and can be taken out of the sputum - collecting box 622, which is convenient for medical staff to pour, clean, and perform subsequent inspections on the sputum;

[0063] The upper end of the sputum - discharging pipe 623 is connected to a guiding sputum pipe 626. The guiding sputum pipe 626 further extends the sputum transmission channel, enabling the sputum - discharging pipe 623 to be better connected to the sputum - discharging face mask 627. At the same time, the length and direction can be adjusted as needed, which is convenient for patients to use the sputum - discharging face mask 627. The upper end of the guiding sputum pipe 626 is connected to the sputum - discharging face mask 627. The sputum - discharging face mask 627 fits the patient's face, facilitating the patient to cough up sputum into the face mask and then enter the sputum - collecting box 622 through the guiding sputum pipe 626 and the sputum - discharging pipe 623. The sputum - discharging face mask 627 is sleeved and placed in the fixed ring 621. The sleeved - card method is convenient for the installation and disassembly of the sputum - discharging face mask 627, facilitating medical staff to clean and replace it to ensure hygiene.

[0064] As Figure 1 、 2As shown, in this embodiment, a headrest 12 is provided in the middle of the front side of the upper surface of the backboard 1. The headrest 12 is used to support the patient's head and improve the comfort of the patient during postural drainage. A sound sensor 13 is provided on the left side of the headrest 12. The sound sensor can detect the patient's voice, such as coughing sounds, etc. When the patient's cough is detected, it can be fed back to the control system, causing the device to make corresponding reactions, such as adjusting the working state of the back-patting and sputum-draining mechanism 6 to assist the patient in better discharging sputum.

[0065] As Figure 1 As shown, in this embodiment, a headboard 41 is provided on the front side of the bed body 4. A display screen 42 is provided on the headboard 41. The display screen 42 is used to display the working state information of the device, such as the angle of postural adjustment, the working parameters of the air pump, the relevant monitoring data of the patient, etc., which is convenient for medical staff and patients to view. Control buttons 43 are provided below the display screen 42. The control buttons 43 are used for medical staff or patients to manually operate the device, such as adjusting the posture, controlling the working of the back-patting and sputum-draining mechanism 6, etc., to achieve convenient control of the device;

[0066] Fences 44 are provided on the left, right, and lower sides of the bed body 4. The fences 44 play a protective role, preventing the patient from rolling off the bed during postural adjustment. At the same time, they can also make the structure of the bed body 4 more complete, increasing the stability and safety of the bed body 4.

[0067] The working principle and usage process of this technical solution are as follows: During use, when postural drainage needs to be performed on the patient, medical staff can operate the postural adjustment mechanism 5 through the control buttons 43 on the headboard 41 according to the patient's condition and drainage requirements. If the lifting posture needs to be adjusted, control the air pump a5108 to work. The air pump a5108 changes the length of the extension rod a5107 by inflating and deflating. The extension rod a5107 drives the support rod 5105 to expand and contract under the connection of the snap ring a5106, and then makes the backboard 1 and the hip and leg board 2, and the hip and leg board 2 and the lower limb board 3 rotate around the rotating shaft a5101 and the rotating shaft b5102 to achieve the lifting action. At the same time, the fixed shaft 5103 on the hip and leg board 2 remains fixed in the fixed groove 5111 of the plate groove a5109, and the roller 5104 on the lower limb board 3 rolls in the rolling groove 5112 to cooperate to complete the adjustment of the lifting posture, so that the semi-sitting position or orthopneic position of the patient can be achieved;

[0068] When the lateral tilt posture is needed, control the air pump b526 to work. The air pump b526 changes the length of the extension rod b525. The extension rod b525 drives the lateral tilt plate 522 to rotate around the rotating shaft c523 through the snap ring b524, so that a part of the backboard 1 or the hip and leg board 2 rotates to achieve lateral tilt, so that the left and right lateral tilt positions of the patient can be achieved;

[0069] To adjust the pitching position, control the air pumps c532 in the air pump slots c531 at the four corners of the bed body 4 to work. The air pumps c532 inflate and deflate to make the telescopic support rods 5335105 telescopic, changing the heights of the four corners of the bed body 4, realizing the overall pitching of the bed body 4, so as to achieve the head-down and feet-up position or the head-up and feet-down position of the patient;

[0070] When patting the back to assist in expectoration, the air pump d612 works to drive the telescopic rod 613 to expand and contract, making the back patting pad 614 move up and down to pat the patient's back. The pressure sensing pad 615 detects the patting pressure and feeds back, so as to adjust the patting intensity through the control button 43 and the display screen 42;

[0071] When the patient expectorates, the sputum is coughed into the expectoration mask 627, enters the sputum collection box 622 through the sputum guiding tube 626 and the sputum discharging tube 623. The air purifier 624 purifies the air in the sputum collection box 622, and the sputum is collected in the sputum discharging box 625 for subsequent treatment.

[0072] The present invention has been further described above in conjunction with the embodiments, but the present invention is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
