[0018] Example See also Figures 1 to 8 As shown, a clustered sputum suction device for rehabilitation in an embodiment of the present application includes a sputum suction tube 1, and the sputum suction tube 1 also includes: a discharge tube 2, the discharge tube 2 is used to discharge the sucked sputum and can be connected to other collection devices. If the patient's physical condition permits, it can also be connected to a negative pressure device. In addition, the device also includes a power mechanism 3, a sputum suction end 4 arranged on the sputum suction tube 1, a plurality of bending strips 5 located on the sputum suction end 4, and a winding mechanism 6 located inside the sputum suction tube 1.

[0019] Among them, the discharge tube 2 is connected to the side wall of the suction tube 1 located at the end outside the human body; the power mechanism 3 is arranged on the end of the suction tube 1 located at the end outside the human body; the suction end 4 is arranged at the end of the suction tube 1 located inside the human body; a plurality of bending strips 5 are arranged on the side wall of the suction end 4, and a suction gap is formed between the plurality of bending strips 5, and one of the states of the bending strips 5 is a bending shape. When the bending strips 5 are in the bent state, the bending strips 5 protrude from the suction tube 1, and the suction gap is increased; the winding mechanism 6 can be movably arranged on the inner side of the suction end 4, and can contact the sputum entering the suction end 4, and apply a pulling force in the inner direction of the suction end 4 to the sputum.

[0020] In the clustered sputum suction device for rehabilitation, the sputum suction tube 1 is the main channel for extracting sputum from the patient's body. The sputum suction end 4 is arranged on the end of the sputum suction tube 1 placed on the inner side of the human body, and is used to contact and suck the sputum; the discharge tube 2 is connected to the side wall of the sputum suction tube 1 at the end outside the human body, and is used to discharge the extracted sputum out of the body; the power mechanism 3 is installed on the outer end of the sputum suction tube 1 to provide driving force to ensure the smooth progress of the sputum suction process; a plurality of bending strips 5 are arranged on the side wall of the sputum suction end 4, and a sputum suction gap is formed by bending. When the bending strip 5 is in a bent state, the bending strip 5 protrudes out of the sputum suction tube 1, so that the suction gap is increased, thereby increasing the surface area of ​​sputum suction, which is helpful to improve the suction efficiency of sputum; the winding mechanism 6 is located inside the sputum suction end 4, and the winding mechanism 6 can contact with the sputum entering the sputum suction end 4, and apply tension to the sputum, pulling it toward the inside of the sputum suction tube 1, further accelerating the discharge of sputum; rather than using negative pressure to suction sputum, taking into account the sputum suction needs of special patients, the overall structure of the device forms a safer sputum suction mechanism through the flexible change of the bending strip 5 and the cooperation of the winding mechanism 6, thereby enhancing the rehabilitation effect of special patients.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, in some examples, further, the power mechanism 3 includes: a pressing block 31, a return assembly 32, a driving motor 33, a docking assembly 34 and a switch 35, the pressing block 31 is fixedly arranged at the end of the suction tube 1; the return assembly 32 is arranged in the pressing block 31 and connected to the winding mechanism 6, for moving the winding mechanism 6 along the length direction of the suction tube 1; the driving motor 33 is partially embedded in the pressing block 31; one end of the docking assembly 34 is connected to the output end of the driving motor 33, and the other end is connected to the winding mechanism 6; the switch 35 is connected to the controller of the driving motor 33, and the switch 35 protrudes from the pressing block 31.

[0022] In this example, the specific structure of the power mechanism 3 is further disclosed, the core of which is to realize the driving and control of the winding mechanism 6; specifically, the pressing block 31 is fixed to the outer end of the suction tube 1 (the end away from the human respiratory tract), serving as the support and external base shell of the entire power mechanism 3; the return component 32 is arranged inside the pressing block 31, connected to the winding mechanism 6, and its function is to prompt the winding mechanism 6 to move along the length direction of the suction tube 1, thereby pulling the winding mechanism and the suction tube 1 to produce relative movement, forcing the bending strip 5 on the suction end 4 at the front end of the suction tube 1 to change from a straight line to a bent shape, further expanding the suction gap, and at the same time increasing the inner cavity volume of the suction end 4, so that sputum can more easily enter the inner cavity of the suction end 4, thereby creating favorable conditions for further collection of sputum, and the driving motor 33 is also partially embedded in one side of the pressing block 31. 3 provides power for the rotation of the entire wave winding mechanism, the purpose of which is to drive the winding mechanism 6 to move, thereby further applying tension to the sputum that has entered the sputum suction tube 1, so that the sputum tissue can be rolled into the inner cavity of the sputum suction tube 1 from the respiratory tract; the docking component 34 serves as a connecting bridge between the drive motor 33 and the winding mechanism 6, and drives the winding mechanism 6 through the rotation or linear movement of the motor, while also allowing the winding mechanism 6 to move along the length direction of the sputum suction tube 1 and always maintain a transmission connection relationship; the switch 35 is connected to the controller of the drive motor 33 and protrudes from the outside of the pressing block 31, so that the operator can control the start and stop of the motor through the switch 35, thereby realizing precise control of the sputum suction process; therefore, the setting of this example enables the power mechanism 3 to efficiently drive the winding mechanism 6, ensure the smooth suction and discharge of sputum, and enhance the operability and convenience of use of the device.

[0023] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some examples, further, a spherical head 11 is provided on the end face of one end of the suction tube 1 located in the human body, the spherical head 11 is a solid structure, one end of the bending strip 5 is connected to the edge of the spherical head 11, and a first bending portion 51 is also provided on the bending strip 5, and the first bending portion 51 is located in the middle position of the bending strip 5.

[0024] It can be understood that the suction tube 1 is located at one end inside the human body and is provided with a solid spherical head 11. The setting of the solid sphere makes its head structure strong and not easy to deform. At the same time, it can also provide a good setting condition for the limit seat 64, so that the spherical head 11 can be driven to move after following the movement of the winding mechanism 6. The outer wall shape of the spherical head 11 mainly optimizes the structure of the suction end 4, making it smoother when entering the body and reducing damage to the body tissue; one end of the bending strip 5 is fixedly connected to the edge of the spherical head 11 to ensure that it remains stable during the suction process ; The design of the bending strip 5 makes it have a certain flexibility, wherein the first bending portion 51 is located in the middle position of the bending strip 5, and this design increases the flexibility of the bending strip 5; during the suction process, the bending strip 5 can switch between different states as needed, and the existence of the first bending portion 51 helps to control the shape and angle of the bending strip 5, thereby effectively increasing the suction gap during suction and improving the suction efficiency; the coordinated design of the spherical head 11 and the bending strip 5 not only helps to guide sputum into the suction tube 1, but also prevents damage caused by tissue contact during suction, thereby ensuring the safety and effectiveness of the device.

[0025] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in some examples, further, the winding mechanism 6 includes: a rotating rod 61, a spiral blade 62, a winding portion 63 and a limit seat 64. The rotating rod 61 is rotatable around its own axis and is arranged in the middle of the inner cavity of the suction tube 1; the spiral blade 62 is fixedly arranged on the outer side of the middle outer wall of the rotating rod 61, and is adjacent to one side of the suction end 4; the winding portion 63 can be movably arranged on the outer wall of the rotating rod 61, and is located on the inner side of the suction end 4; the limit seat 64 can be rotatably arranged in the inner cavity of the spherical head 11, and the limit seat 64 is fixedly connected to the end of the rotating rod 61.

[0026] It should be noted that the winding mechanism 6 provided in this example further realizes an effective sputum suction process; specifically, the rotating rod 61 is located in the middle of the inner cavity of the sputum suction tube 1, one end of which is connected to the power mechanism 3 and can rotate under the action of the power mechanism 3; the spiral blade 62 is fixed on the middle outer wall of the rotating rod 61, close to the sputum suction end 4, and generates thrust through rotation, which helps to guide the sputum at the sputum suction end 4 into the interior of the sputum suction tube 1, and finally discharged to the outside of the device through the discharge pipe 2; the winding part 63 is movably arranged on the outer wall of the rotating rod 61 and is located on the inner side of the sputum suction end 4, and it can move the sputum along with the movement of the rotating rod 61 The liquid is moved and entangled, and the sputum is gradually pulled to the inner side of the sputum suction tube 1, and the sputum is further pushed into the discharge tube 2; the limit seat 64 is located in the inner cavity of the spherical head 11, and the limit seat 64 is fixedly connected to the end of the rotating rod 61. The limit seat 64 can rotate together with the rotation of the rotating rod 61. When the rotating rod 61 is subjected to the pulling force of the return component 32, the setting of the limit seat 64 can pull the spherical head 11 to move together; therefore, this example can effectively promote and guide the discharge of sputum through the cooperation of the rotating rod 61, the spiral blade 62, the winding part 63 and the limit seat 64, thereby improving the working efficiency of the sputum suction device.

[0027] In some examples, further, a pressure relief gap is left between the outer wall of the spiral blade 62 and the inner wall of the sputum suction tube 1 .

[0028] It should be noted that the device can also be used for special patients, such as patients with respiratory bleeding and emphysema. The spiral blade 62 is set during its operation. While slowly drawing out the sputum from the suction end 4, it also applies a small amount of pressure to the suction end 4, forming a micro-negative pressure environment in the suction end 4. Through such a micro-negative pressure environment, the sputum can better enter the suction end 4 from the respiratory tract. At the same time, compared with the normal negative pressure suction equipment, the pressure is significantly weakened, reducing the discomfort to special patients. In addition, the pressure relief gap reserved between the outer wall of the spiral blade 62 and the inner wall of the suction tube 1 allows gas or liquid to be discharged during the suction process, preventing excessive negative pressure from accumulating in the suction end 4, thereby avoiding patient-unfriendly situations caused by excessive pressure; improving the safety of the entire device; and improving the overall performance of the device and the patient's comfort.

[0029] like Figure 4 As shown, in some examples, further, the return assembly 32 includes: two pressing plates 321, a tilting rod 322 and a movable groove 323, the two pressing plates 321 are symmetrically arranged on the inner wall of the inner cavity of the pressing block 31; one end of the tilting rod 322 is connected to the pressing plate 321, and the other end is movably mounted on the outer wall of the rotating rod 61, and also abuts against the end of the docking assembly 34; the movable groove 323 is opened on the outer wall of the suction tube 1 located on the inner side of the pressing block 31, and the tilting rod 322 is located in the movable groove 323.

[0030] It can be understood that, in this example, the return component 32 serves as an operating component for the staff, and its function is to ensure that the winding mechanism 6 can move smoothly in the sputum suction tube 1 and accurately control the shape of the sputum suction end 4, and switch the straight state and the bent state of the bending strip 5 (when entering the human body, it can enter in a small volume state, and at this time the bending strip 5 is a straight device. When reaching the sputum suction position, the bending strip 5 can be switched to a bent state, which is more conducive to sputum collection); specifically, the two pressing pieces 321 are symmetrically arranged on the inner wall of the inner cavity of the pressing block 31, and its function is to press the inclined rod 3 through the pressing piece 321 22 applies force; so that the staff can apply force to the pressing piece 321 from both sides at the same time, one end of the tilting rod 322 is connected to the pressing piece 321, and the other end is sleeved on the outer wall of the rotating rod 61, and at the same time abuts against the end of the docking assembly 34; when the pressing piece 321 is pressed, the tilting rod 322 will move accordingly and become more inclined, and through the change of its inclination angle, the winding mechanism 6 will be moved along the length direction of the suction tube 1, thereby controlling the bending strip 5 to bend and changing the shape of the suction end 4; ensuring smooth sputum guidance and discharge during the suction process, while improving the convenience of operation and the working efficiency of the device.

[0031] like Figure 3 , Figure 5 and Figure 8 As shown, in some examples, further, the winding portion 63 includes: two movable sleeves 631, two connecting rods 632 and a second bending portion 633, the two movable sleeves 631 can be movably mounted on the outer wall of the rotating rod 61 located in the suction end 4; one end of the two connecting rods 632 is respectively connected to the outer wall of the corresponding movable sleeve 631; the second bending portion 633 is connected between the two connecting rods 632, and the second bending portion 633 corresponds to the position of the first bending portion 51.

[0032] In this example, the winding portion 63 realizes the winding and guidance of sputum; in this example, the two movable sleeves 631 are respectively movably mounted on the outer wall of the rotating rod 61 located in the sputum suction end 4, and the two movable sleeves 631 can move along the length direction of the rotating rod 61; the connecting rod 632 is arranged on the inner side of the movable sleeve 631, and the second bending portion 633 is arranged on the inner side of the two connecting rods 632, so the two movable sleeves 631, the two connecting rods 632 and the second bending portion 633 together constitute an integrated structure mounted on the outer wall of the rotating rod 61, and during the rotation of the rotating rod 61, the design of the second bending portion 633 enables this part to correspond to the position of the first bending portion 51, forming a The second bent portion 633 will be bent into a structure with good elasticity and flexibility, and the second bent portion 633 will also bend and approach the first bent portion 51 under the action of centrifugal force. At this time, the second bent portion 633 will be located in the inner cavity of the enlarged part of the sputum suction end 4, and can contact and adsorb the sputum entering the inner cavity of the sputum suction end 4; during the sputum suction process, as the rotating rod 61 rotates, the movable sleeve 631 and the connecting rod 632 drive the second bent portion 633 to perform a winding movement, which can effectively wrap around and guide the sputum, push it into the inside of the sputum suction tube 1, and finally be sucked out; therefore, through the setting of this example, the winding portion 63 can flexibly and accurately handle the sputum, improve the sputum suction efficiency, and prevent the pipeline from being blocked or sputum residue.

[0033] In some examples, further, a water-absorbing layer (not shown in the figure) is provided on the outer wall of the second bending portion 633; ​​the water-absorbing layer is provided on the outer wall of the second bending portion 633 to provide a stronger adsorption force, thereby effectively enhancing the ability to coil and guide sputum; during the sputum suction process, when the sputum contacts the second bending portion 633, the water-absorbing layer can quickly absorb the sputum, making it easier to coil around the bending portion and be guided into the sputum suction tube 1, ensuring that the sputum suction process is smoother.

[0034] In some examples, further, the docking assembly 34 includes a seat body and a plug-in block, the seat body is provided with a slot matching the shape of the plug-in block, the plug-in block can move in the slot along the length direction of the rotating rod 61, wherein the plug-in block is non-cylindrical.

[0035] In this example, the docking assembly 34 realizes the stable connection and flexible adjustment function of the dialing mechanism 6 and the power mechanism 3. Specifically, a slot matching the shape of the plug-in block is provided in the seat body to ensure that the plug-in block can be confined in the seat body and can be displaced along the length direction of the rotating rod 61 to cooperate with the control of the return assembly 32. The non-cylindrical design of the plug-in block further enhances the degree of fit with the seat body, and can better withstand the force from the rotating rod 61, so that after the motor rotates, it can synchronously drive the rotating rod 61 to rotate through the docking assembly 34, and also provide the ability of the rotating rod 61 to move along its length direction, so as to realize the flexible switching of the shape of the suction end 4 at the appropriate time to perform the suction operation.
