The adjusting rod 10 is slidably installed on the inner wall of the guide groove 13, and the roller 11 is rotatably installed on the circumferential surface of the adjusting rod 10. The movement of the telescopic rod 7 drives the suction head 8 to deform and change the direction of the suction head 8, thereby realizing the change of the angle, so that the nursing staff can adjust the angle of the suction tube body 2 according to the specific situation of the patient (such as body position, airway condition, etc.), helping the nursing staff to enter the airway more conveniently, perform more precise suction operations, and avoid some limitations caused by the fixed angle; wherein, the surface of the fixed frame 4 is provided with a limiting device for preventing the roller 11 from shaking and causing the angle of the suction head 8 to change.

[0022] A baffle 14 is slidably penetrated through the top of the purification frame 1, and a No. 1 spring 15 is arranged between the baffle 14 and the purification frame 1. An air hole 16 is opened on the surface of the baffle 14. When the baffle 14 is pressed, the baffle 14 moves downward so that the air hole 16 on its surface is connected with the suction pipe 3, thereby realizing the suction of sputum, avoiding the discomfort of the patient caused by starting the sputum suction tube body 2 when the angle is not adjusted accurately, and improving the convenience and comfort of sputum suction.

[0023] The guide groove 13 is inclined, the suction tube body 2 is elastic, the water bag 5 is elastic, the conduction tube 6 is elastic, the suction head 8 is elastic, two water bags 5 are provided, and the two water bags 5 are symmetrically distributed with the fixed frame 4 as the center. The two water bags 5 can realize the change of the angles on both sides of the suction head 8, thereby improving the convenience of suctioning.

[0024] Disinfectant is stored inside the purification frame 1, and the sucked sputum directly enters the disinfectant to avoid secondary infection. The conduction tube 6 is fixedly penetrated through the inner and outer walls of the suction tube body 2. A scale is provided on the surface of the suction tube body 2. The scale can facilitate the nursing staff to penetrate the depth of the suction tube body 2.

When the angle adjustment is completed, the baffle 14 is pressed downward, and the baffle 14 moves downward so that the air holes 16 on its surface are connected with the suction tube 3, thereby realizing the suction work, avoiding the discomfort of the patient caused by starting the suction tube body 2 when the angle is not adjusted accurately, and improving the convenience and comfort of suction.

[0026] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, the limiting device includes a lifting plate 171, a U-shaped plate 172, a block 173 and a paddle 174. The lifting plate 171 is slidably mounted on the surface of the fixed frame 4. A moving groove 175 is provided on the surface of the fixed frame 4. The U-shaped plate 172 is slidably mounted on the inner wall of the moving groove 175. A placement groove 176 is provided on the surface of the U-shaped plate 172. The block 173 is slidably mounted inside the placement groove 176. The paddle 174 is fixedly mounted above the U-shaped plate 172. The block 173 moves to limit the lifting plate 171, thereby preventing the roller 11 from resetting under the elasticity of the water bag 5 itself, resulting in a change in the angle of the suction head 8 during the suction process, thereby increasing the patient's discomfort and improving the quality of nursing.

[0027] A limiting groove 177 is provided on the surface of the lifting plate 171. When the adjusting rod 10 moves downward, the lifting plate 171 will be driven to move downward through the limiting groove 177. The inner wall of the limiting groove 177 contacts the adjusting rod 10. A clamping groove 178 is provided on the end of the lifting plate 171 away from the adjusting rod 10. The clamping block 173 moves out of contact with the clamping groove 178 and releases the limit on the lifting plate 171. Then, the angle of the suction head 8 is corrected by the roller 11, which facilitates the extraction of the suction tube body 2 and improves the efficiency of nursing.

[0028] A No. 2 spring 179 is arranged between the block 173 and the inner wall of the placement groove 176, and the No. 2 spring 179 can drive the block 173 to reset. A No. 3 spring 1710 is arranged between the U-shaped plate 172 and the inner wall of the movable groove 175, and the No. 3 spring 1710 can drive the U-shaped plate 172 to reset. Since the elastic coefficient of the No. 3 spring 1710 is greater than that of the No. 2 spring 179, it can prevent the U-shaped plate 172 from following the movement when the block 173 is squeezed by the lifting plate 171.

[0029] One side of the clamping block 173 close to the clamping slot 178 is set as a bevel surface 1. Two lifting plates 171 are provided. The two lifting plates 171 are symmetrically distributed with the fixing frame 4 as the center. The two lifting plates 171 can limit the rollers 11 on both sides.

[0030] It also includes an anti-accidental touch device, which includes a fixed block 181, a connecting rod 182, a limiting plate 183, a receiving block 184 and a limiting rod 185. When the baffle 14 moves downward, the fixed block 181 will be driven to move downward. The downward movement of the fixed block 181 drives one end of the connecting rod 182 to move downward. The fixed block 181 is fixedly installed on the circumferential surface of the baffle 14, the connecting rod 182 is rotatably installed inside the fixed block 181D, the limiting plate 183 is slidably installed above the fixed frame 4, and the receiving block 184 is fixedly installed on the limiting plate On one side of 183 close to the fixed block 181, a connecting groove 186 is provided on the surface of the fixed frame 4, and the limiting rod 185 is slidably installed inside the connecting groove 186. The receiving block 184 moves to drive the limiting plate 183 to move, and the limiting plate 183 moves to contact and squeeze the U-shaped plate 172 to achieve the limitation of the U-shaped plate 172. After the limitation is completed, it can effectively prevent medical staff from accidentally touching the paddle 174, causing the roller 11 to reset, thereby causing the angle of the suction head 8 to change, further reducing the patient's discomfort during the suction care process and improving the quality of care.

[0031] One end of the connecting rod 182 away from the fixed block 181 is rotatably connected to the receiving block 184, and a No. 4 spring 187 is arranged between the limit rod 185 and the connecting groove 186. The side of the limit rod 185 close to the limit plate 183 is arranged as a second bevel. The limit rod 185 fixes the limit plate 183 under the action of the No. 4 spring 187, so that the air hole 16 on the surface of the baffle 14 is always connected with the exhaust pipe 3, and the nursing staff does not need to press the baffle 14 for a long time, so that the nursing staff can perform suction care for the patient with both hands, thereby improving the efficiency of suction care and further reducing the discomfort of the patient.

[0032] When the present embodiment is working, when the adjusting rod 10 moves downward, it will drive the lifting plate 171 to move downward through the limiting groove 177. The lifting plate 171 moves downward and squeezes the block 173 to move in the direction close to the placement groove 176. The block 173 moves and squeezes the No. 2 spring 179 to contract. When the lifting plate 171 stops moving, the block 173 will move in the direction close to the lifting plate 171 under the action of the contracted No. 2 spring 179. The block 173 moves and enters the inside of the groove 178 on the surface of the lifting plate 171, thereby limiting the lifting plate 171 and preventing the roller 11 from being pressed against the water bag 5 itself. The elasticity causes the angle of the suction head 8 to change during the suction process, thereby increasing the patient's discomfort and improving the quality of nursing. At the same time, when the nursing is completed, the paddle 174 is moved away from the fixed frame 4, so that the paddle 174 drives the U-shaped plate 172 to move away from the lifting plate 171. The movement of the U-shaped plate 172 drives the block 173 to move. The block 173 moves out of contact with the slot 178 and releases the limit on the lifting plate 171. Then, the angle of the suction head 8 is corrected by the roller 11, which facilitates the extraction of the suction tube body 2 and improves the efficiency of nursing.

[0033] When the baffle 14 moves downward, it will drive the fixing block 181 to move downward, and the fixing block 181 moves downward to drive one end of the connecting rod 182 to move downward, and one end of the connecting rod 182 moves downward to drive the receiving block 184 to move toward the fixed frame 4 through the other end, and the receiving block 184 moves to drive the limiting plate 183 to move, and the limiting plate 183 moves to contact and squeeze the U-shaped plate 172 to limit the U-shaped plate 172. After the limiting is completed, it can effectively prevent medical staff from accidentally touching the paddle 174, causing the roller 11 to reset, thereby causing the angle of the suction head 8 to change, further reducing The patient's discomfort during suction care is reduced, and the quality of care is improved. At the same time, when the limit plate 183 moves, it contacts and squeezes the limit rod 185 to move away from the limit plate 183. After the limit rod 185 moves, it squeezes the No. 4 spring 187 to contract, and is reset under the action of the No. 4 spring 187 to fix the limit plate 183, so that the air hole 16 on the surface of the baffle 14 is always connected to the exhaust pipe 3. There is no need for the nursing staff to press the baffle 14 for a long time, so that the nursing staff can perform suction care for the patient with both hands, thereby improving the efficiency of suction care and further reducing the patient's discomfort.
