Detailed implementation manners

[0042] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0043] Referring to Figure 1 As shown, the present invention provides a technical solution: a sputum crust removal device, including a cylinder 1 for storing sputum crusts and a sputum crust suction device 3. One end of the cylinder 1 is fixedly connected with a push plate 2, and a scale 6 for judging the number of sputum crusts in the cylinder 1 is arranged on the outer wall of the cylinder 1.

[0044] Among them, the sputum crust suction device 3 is located on the cylinder 1. The sputum crust suction device 3 is used for sucking and removing sputum crusts. An auxiliary device 4 for controlling the movement of the circular plate 303 is arranged on one side of the circular plate 303, and an opening and closing device 5 for facilitating personnel to clean the inner wall of the cylinder 1 or facilitating personnel to take out the sputum crusts inside the cylinder 1 is arranged on the outer wall of the cylinder 1.

[0045] The following specifically describes the specific settings and functions of its sputum crust suction device 3, auxiliary device 4 and opening and closing device 5.

[0046] Referring to Figures 2 to 6As shown in the figure, in this embodiment: The sputum crust aspiration device 3 includes several limiting bolts 305 that play a supporting role, a fixing bolt 307 that plays a supporting role, and a piston 302 for extracting sputum crusts. The piston 302 slides on the inner wall of the cylinder 1. One end of the piston 302 is fixedly connected to a push rod 301 for facilitating personnel to control the piston 302. The end of the push rod 301 away from the piston 302 is fixedly connected to a round plate 303 for facilitating the control of the push rod 301. The limiting bolts 305 are fixed on the inner wall of the cylinder 1. A connecting rod 304 that plays a connecting role is rotatably connected to the inner walls of several limiting bolts 305. The connecting rod 304 is movably connected to the piston 302. One end of the connecting rod 304 is fixedly connected to a driven bevel gear 306 for driving the connecting rod 304 to rotate. The fixing bolt 307 is fixedly connected to the side of the push plate 2 away from the cylinder 1. A connecting rod 325 that plays a supporting role is rotatably connected to the inner wall of the fixing bolt 307. One end of the connecting rod 325 is rotatably connected to a driving bevel gear 308 for driving the driven bevel gear 306 to rotate. The driving bevel gear 308 meshes with the driven bevel gear 306. The end of the connecting rod 325 away from the driving bevel gear 308 is fixedly connected to a turning plate 309 for facilitating personnel to turn the connecting rod 325. Several crushing knives 310 for crushing sputum crusts are fixedly connected to the arc surface of the connecting rod 304. The crushing knives 310 are evenly distributed on the arc surface of the connecting rod 325. A round hole 314 is opened at one end of the cylinder 1 away from the push plate 2. One end of the cylinder 1 is attached to a suction pipe 312 communicating with the round hole 314. The crushing knives 310 are located inside the suction pipe 312. A water storage tank 319 is fixedly connected to the outer wall of the cylinder 1. A water pump for conveying water is installed inside the water storage tank 319. A water inlet pipe 320 for injecting water into the water storage tank 319 is fixedly communicated with one side of the outer wall of the water storage tank 319. A connecting pipe 321 is fixedly communicated with one side of the outer wall of the water storage tank 319. The end of the connecting pipe 321 away from the water storage tank 319 is fixedly communicated with an annular pipe 323. The annular pipe 323 is sleeved on the outer wall of the suction pipe 312. Several spray heads 324 for spraying water on the patient's throat are fixedly communicated with the outer wall of the annular pipe 323. When it is necessary to use this device to remove the sputum crust at the patient's throat, first move the cylinder 1 to drive the suction pipe 312 and insert the suction pipe 312 into the position with sputum crust in the patient's throat. When the suction pipe 312 reaches the position with sputum crust in the patient's throat, the medical staff needs to stabilize the cylinder 1 to prevent it from shaking. Then start the water pump inside the water storage tank 319, so that the water inside the water storage tank 319 flows along the connecting pipe 321 and the annular pipe 323 to the spray heads 324, so that the spray heads 324 can spray water to moisten the position with sputum crust in the patient's throat. Through moistening, the sputum crust becomes thinner, the viscosity is reduced, and the adhesion between the sputum crust and the patient's throat is reduced. After the sputum crust is moistened, then pull the round plate 303 to drive the push rod 301, and the push rod 301 drives the piston 302 to move the piston 302 along the inner wall of the cylinder 1. At this time, the suction pipe 312 can aspirate the sputum crust.When the sputum scab enters the inside of the suction tube 312, the personnel first pause the movement of the piston 302, and first rotate the rotating plate 309 to drive the connecting rod 325 to rotate, so that the connecting rod 325 rotates along the inner wall of the fixing bolt 307 and drives the active bevel gear 308 to rotate, the active bevel gear 308 drives the driven bevel gear 306 to rotate, the driven bevel gear 306 drives the connecting rod 304 to rotate, and the connecting rod 304 drives the crushing knife 310 inside the suction tube 312 to rotate, so that the crushing knife 310 can crush the sputum scab inside the suction tube 312, so as to avoid the sputum scab from clogging the pipeline during the suction process. When the sputum scab enters the inside of the cylinder 1, the sputum scab removal operation can be completed.

[0047] The outer wall of the straw 312 is fixedly connected to a partition 315, and a screw hole 316 is opened on the side of the partition 315. The end of the cylinder 1 close to the straw 312 is fixedly connected to a fixing seat 317. The inner wall of the fixing seat 317 fits the side of the partition 315. The side of the fixing seat 317 is threaded with a screw 318 for fixing the partition 315. The size of the screw 318 and the screw hole 316 are adapted. When the straw 312 needs to be disassembled and disinfected after use, the screw 318 is first rotated to separate from the screw hole 316 on the partition 315. When the screw 318 is separated from the screw hole 316, the straw 312 is moved to drive the partition 315 so that the partition 315 and the fixing seat 317 are connected. 17 is separated, the disassembly of the straw 312 is completed, and then the personnel can easily clean and disinfect the entire straw 312. After the disinfection of the straw 312 is completed, the straw 312 is moved to connect with the circular hole 314. At the same time, the partition 315 on the outer wall of the straw 312 needs to be placed into the inner wall of the fixing seat 317. When the screw hole 316 on the partition 315 is aligned with the screw rod 318 on the fixing seat 317, the screw rod 318 is rotated to connect with the screw hole 316, and the installation of the straw 312 is completed. By setting the above structure, personnel can easily disassemble and assemble the straw 312, so that it is convenient for personnel to disassemble and disinfect the straw 312 after use.

[0048] One end of the straw 312 away from the cylinder 1 is fixedly connected to a connecting disk 313 for expanding the entrance of the straw 312 . The cross section of the connecting disk 313 is truncated cone-shaped. The connecting disk 313 can expand the entrance of the straw 312 so that the sputum crust can be sucked into the straw 312 more smoothly.

[0049] One end of the connecting rod 304 away from the driven bevel gear 306 is fixedly connected with a cone head 311, and the cross-section of the cone head 311 is conical. After the sputum scab in the patient's mouth is sucked into the straw 312, the sputum scab will first contact the cone head 311. At this time, the sharp cone head 311 can divide the sputum scab into several parts, thereby further breaking up the sputum scab.

[0050] A plurality of limit bolts 305 for binding the connecting pipe 321 are sleeved on the outer wall of the connecting pipe 321. The limit ring 322 is fixedly connected to the outer wall of the cylinder 1. The cross-section of the limit ring 322 is in a "U" shape. The limit ring 322 can bind the connecting pipe 321, thereby minimizing the shaking or deviation of the connecting pipe 321 during use.

[0051] A sealing ring 326 for improving the sealing performance between the suction pipe 312 and the cylinder 1 is fixedly connected to the outer wall of the suction pipe 312. One side of the sealing ring 326 is in contact with one end of the cylinder 1. The sealing ring 326 can block the gap between the suction pipe 312 and the cylinder 1, thereby improving the sealing performance between the suction pipe 312 and the cylinder 1.

[0052] Refer to Figure 7 and Figure 8 As shown in the figure, in this embodiment: The auxiliary device 4 includes a rotating seat 41 that plays a supporting role. A rotating shaft 42 is rotatably penetrated through the inner wall of the rotating seat 41. A pull ring 43 for controlling the circular plate 303 is fixedly connected to the arc surface of the rotating shaft 42. A sliding hole 44 is opened on one side of the rotating seat 41. The center of the sliding hole 44 is coaxial with the axis of rotation of the rotating shaft 42. A sliding rod 45 for improving the stability of the rotation process of the pull ring 43 is slidably connected to the inner wall of the sliding hole 44. One end of the sliding rod 45 is fixedly connected to the outer wall of the pull ring 43. An adjusting ring 46 for locking the pull ring 43 is threadedly connected to the arc surface of the sliding rod 45. When it is necessary to adjust the pull ring 43 to an appropriate angle, first rotate the adjusting ring 46 to separate it from the rotating seat 41, and then rotate the pull ring 43 to drive the rotating shaft 42, so that the rotating shaft 42 rotates along the inner wall of the rotating seat 41. While the pull ring 43 rotates, it will drive the sliding rod 45 to slide along the inner wall of the sliding hole 44, thereby improving the stability of the rotation process of the pull ring 43. When the pull ring 43 rotates to an appropriate angle, then rotate the adjusting ring 46 to abut against the rotating seat 41, and the angle of the pull ring 43 can be locked. Subsequently, the operator can comfortably control the pull ring 43 to control the circular plate 303, the push rod 301, and the piston 302.

[0053] A rubber pad 47 is fixedly connected to the side of the adjusting ring 46 close to the rotating seat 41. The cross-section of the rubber pad 47 is circular. The rubber pad 47 can increase the friction on the side of the adjusting ring 46 close to the rotating seat 41, achieving the effect of making the adjusting ring 46 abut against the rotating seat 41 more firmly with the help of the rubber pad 47.

[0054] Refer to Figure 9As shown in the figure, in this embodiment: The opening and closing device 5 includes a rectangular hole 501 and a sealing plate 502 for sealing the rectangular hole 501. The sealing plate 502 is adapted to the size of the rectangular hole 501. Two mounting plates 503 are fixedly connected to one side of the sealing plate 502. A lead screw 504 for driving the movement of the sealing plate 502 is threadedly penetrated through the side surface of the long arm end of the mounting plate 503. One end of the lead screw 504 is rotatably connected to the outer wall of the cylinder 1. The arc surfaces of the two lead screws 504 are fixedly connected with a reel 506 respectively. The arc surfaces of the two reels 506 are drivingly connected with a belt 507 for driving the rotation of the reel 506. A plurality of auxiliary plates 505 for facilitating the rotation of the lead screw 504 by personnel are fixedly connected to the upper end of one of the lead screws 504. By providing the opening and closing device 5, personnel can conveniently adjust the sealing plate 502 to seal or open the rectangular hole 501, thereby facilitating personnel to clean the inner wall of the cylinder 1 or take out the phlegm crust inside the cylinder 1, improving the overall practicality of the phlegm crust removal device. When it is necessary to open the sealing plate 502 to facilitate personnel to clean the inner wall of the cylinder 1 or take out the phlegm crust inside the cylinder 1, first rotate the auxiliary plate 505 to drive one of the lead screws 504 to rotate. This lead screw 504 drives the other lead screw 504 to rotate by means of the reel 506 and the belt 507, so as to drive the two lead screws 504 to rotate synchronously. While the lead screw 504 rotates, it will drive the mounting plate 503 to move along its arc surface. The mounting plate 503 drives the sealing plate 502, so that the sealing plate 502 can be separated from the rectangular hole 501 and gradually move away from the rectangular hole 501. When the sealing plate 502 moves to a suitable position, the rotation of the auxiliary plate 505 can be stopped. Subsequently, personnel can take out the phlegm crust in the cylinder 1 or clean the inside of the cylinder 1 through the sealing plate 502. When the operation is completed, rotate the auxiliary plate 505 to drive one of the lead screws 504 to rotate in the reverse direction. This lead screw 504 drives the other lead screw 504 to rotate in the reverse direction by means of the reel 506 and the belt 507. The lead screw 504 drives the mounting plate 503 to move in the reverse direction. The mounting plate 503 drives the sealing plate 502 to move. When the sealing plate 502 blocks the rectangular hole 501, the rotation of the auxiliary plate 505 can be stopped.

[0055] A positioning plate 508 is fixedly connected to one side of the sealing plate 502. A positioning rod 509 is slidably penetrated through the side surface of the positioning plate 508. One end of the positioning rod 509 is fixedly connected to the outer wall of the cylinder 1. During the movement of the sealing plate 502, the positioning plate 508 fixed on the sealing plate 502 will move along the positioning rod 509, thereby improving the stability of the movement process of the sealing plate 502.

[0056] Detailed usage method: In the present invention, when it is necessary to use this device to remove the phlegm crust at the patient's throat, first move the cylinder 1 to drive the suction pipe 312, and insert the suction pipe 312 into the position with phlegm crust in the patient's throat. After the suction pipe 312 reaches the position with phlegm crust in the patient's throat, the medical staff needs to stabilize the cylinder 1 to prevent it from shaking, and then start the water pump inside the water storage tank 319, so that the water flow inside the water storage tank 319 reaches the nozzle 324 along the connecting pipe 321 and the annular pipe 323, thereby enabling the nozzle 324 to spray water to moisten the position with phlegm crust in the patient's throat. Through moistening, the phlegm crust becomes thinner, reducing its viscosity and the adhesion between the phlegm crust and the patient's throat. After the phlegm crust is moistened, then pull the round plate 303 to drive the push rod 301, and the push rod 301 drives the piston 302, so that the piston 302 moves along the inner wall of the cylinder 1. At this time, the suction pipe 312 can suck the phlegm crust. After the phlegm crust enters the inside of the suction pipe 312, the person first pauses the movement of the piston 302, and first rotates the rotating plate 309 to drive the connecting rod 325 to rotate, so that the connecting rod 325 rotates along the inner wall of the fixed bolt 307 and drives the driving bevel gear 308 to rotate. The driving bevel gear 308 drives the driven bevel gear 306 to rotate, and the driven bevel gear 306 drives the connecting rod 304 to rotate. The connecting rod 304 drives the crushing knife 310 inside the suction pipe 312 to rotate, so that the crushing knife 310 can crush the phlegm crust inside the suction pipe 312, thereby avoiding the blockage of the pipeline by the phlegm crust during the suction process. When the phlegm crust enters the inside of the cylinder 1, the removal operation of the phlegm crust is completed. Among them, when the suction pipe 312 needs to be disassembled and disinfected after use, first rotate the screw rod 318 to separate it from the screw hole 316 on the partition plate 315. After the screw rod 318 is separated from the screw hole 316, then move the suction pipe 312 to drive the partition plate 315, so that the partition plate 315 is separated from the inner wall of the fixed seat 317, and the disassembly of the suction pipe 312 can be completed. Subsequently, the person can conveniently clean and disinfect the entire suction pipe 312. After the suction pipe 312 is disinfected, then move the suction pipe 312 to dock with the round hole 314, and at the same time, the partition plate 315 on the outer wall of the suction pipe 312 needs to be placed inside the inner wall of the fixed seat 317. When the screw hole 316 on the partition plate 315 is aligned with the screw rod 318 on the fixed seat 317, then rotate the screw rod 318 to connect it with the screw hole 316, and the installation of the suction pipe 312 can be completed. By setting the above structure, the person can conveniently disassemble and assemble the suction pipe 312, so that it is convenient for the person to disassemble and disinfect the used suction pipe 312. The sealing ring 326 can block the gap between the suction pipe 312 and the cylinder 1, thereby improving the sealing performance between the suction pipe 312 and the cylinder 1. In addition, the connecting disc 313 can expand the inlet of the suction pipe 312, so that the phlegm crust can be more smoothly sucked into the suction pipe 312. After the phlegm crust in the patient's oral cavity is sucked into the suction pipe 312, the phlegm crust will first contact the cone head 311. At this time, the sharp cone head 311 can divide the phlegm crust into several parts, so as to further crush the phlegm crust. Finally,The limiting ring 322 can restrain the connecting pipe 321, thereby minimizing the risk of the connecting pipe 321 shaking or shifting during use.

[0057] When it is necessary to adjust the pull ring 43 to an appropriate angle, first rotate the adjusting ring 46 to separate it from the rotating seat 41, and then rotate the pull ring 43 to drive the rotating shaft 42, causing the rotating shaft 42 to rotate along the inner wall of the rotating seat 41. While the pull ring 43 is rotating, it will drive the sliding rod 45 to slide along the inner wall of the sliding hole 44, thereby improving the stability of the rotation process of the pull ring 43. When the pull ring 43 rotates to the appropriate angle, then rotate the adjusting ring 46 to abut against the rotating seat 41, and the angle of the pull ring 43 can be locked. Subsequently, the operator can comfortably control the pull ring 43 to control the circular plate 303, the push rod 301, and the piston 302. Among them, the rubber pad 47 can increase the friction on the side of the adjusting ring 46 close to the rotating seat 41, achieving the effect that the adjusting ring 46 can abut more firmly against the rotating seat 41 with the help of the rubber pad 47.

[0058] When it is necessary to open the sealing plate 502 to facilitate the operator to clean the inner wall of the cylinder 1 or take out the phlegm crust inside the cylinder 1, first rotate the auxiliary plate 505 to drive one of the lead screws 504 to rotate. This lead screw 504 drives the other lead screw 504 to rotate through the reel 506 and the belt 507, thereby enabling the two lead screws 504 to rotate synchronously. While the lead screw 504 is rotating, it will drive the mounting plate 503 to move along its arc surface. The mounting plate 503 drives the sealing plate 502, so that the sealing plate 502 can separate from the rectangular hole 501 and gradually move away from the rectangular hole 501. When the sealing plate 502 moves to the appropriate position, stop rotating the auxiliary plate 505. Subsequently, the operator can take out the phlegm crust in the cylinder 1 or clean the inside of the cylinder 1 through the sealing plate 502. After the operation is completed, rotate the auxiliary plate 505 to drive one of the lead screws 504 to rotate in the reverse direction. This lead screw 504 drives the other lead screw 504 to rotate in the reverse direction through the reel 506 and the belt 507. The lead screw 504 drives the mounting plate 503 to move in the reverse direction. The mounting plate 503 drives the sealing plate 502 to move. When the sealing plate 502 blocks the rectangular hole 501, stop rotating the auxiliary plate 505. Among them, during the movement of the sealing plate 502, the positioning plate 508 fixed on the sealing plate 502 will move along the positioning rod 509, thereby improving the stability of the movement process of the sealing plate 502.
