DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10In an embodiment of the present invention, a bedside sputum disinfection device for patients with pulmonary tuberculosis comprises a shell 1; preferably, a cover plate 2 is provided on the top of the shell 1, a second fixing plate 6 is fixedly provided on one side of the shell 1, a first fixing plate 4 is fixedly provided on the other side of the shell 1, a connecting block 3 is fixedly provided on one side of the cover plate 2, the connecting block 3 and the top of the first fixing plate 4 are rotatably connected, a square block 5 is fixedly provided on the side of the cover plate 2 away from the connecting block 3, a base 7 is fixedly provided on the bottom of the shell 1, a fixing mechanism is provided at the bottom center of the shell 1, a transmission mechanism is provided in the first fixing plate 4, the transmission mechanism is transmission-connected to the fixing mechanism, and a conveying mechanism is provided on the side of the fixing mechanism away from the transmission mechanism; when the cover plate 2 is rotated to open, the cover plate 2 drives the transmission mechanism to move downward through the connecting block 3, when the transmission mechanism moves downward, the fixing mechanism is driven to move downward, and when the fixing mechanism moves downward, the conveying mechanism moves upward.

[0030] Two groups of square blocks 5 are symmetrically arranged along the center of the cover plate 2, and limiting holes are arranged in the square block 5. The square block 5 slides and fits with the top of the second fixing plate 6. The end of the limiting hole away from the second fixing plate 6 is elastically connected with a pushing block by a spring, and the two sides of the top of the second fixing plate 6 are elastically connected with limiting blocks extending into the limiting hole for limiting cooperation by a spring. An upward inclined surface is arranged on the end of the limiting block close to the square block 5. When in use, when the cover plate 2 needs to be rotated to open, the pushing block is pressed so that the pushing block moves toward the second fixing plate 6 to push the limiting block out of the limiting hole, thereby allowing the cover plate 2 to rotate upward and open. When the cover plate 2 is rotated to close, the square block 5 will slide and cooperate with the inclined surface on the limiting block, first causing the limiting block to shrink in the second fixing plate 6, and then when the limiting hole corresponds to the limiting block, the limiting block elastically extends into the limiting hole to limit the space between the cover plate 2 and the shell 1.

[0031] A collecting cylinder 8 is arranged at the top of the shell 1, and the collecting cylinder 8 is arranged in a conical structure. A placing bin 9 and a disinfection chamber 10 are arranged in sequence below the collecting cylinder 8 in the shell 1. A partition is arranged between the placing bin 9 and the disinfection chamber 10 for isolation. A disinfectant for disinfecting sputum is arranged in the disinfection chamber 10, and an injection port for filling the disinfection chamber 10 with disinfectant is arranged on the partition. A sealing cover is arranged on the injection port. The bottom of the collecting cylinder 8 is communicated with the top of the placing bin 9. When the cover 2 is opened, the collecting cylinder 8 can collect the sputum coughed up by the person, and then transport it to the placing bin 9 through the collecting cylinder 8, and the placing bin 9 is used to place a collection bottle for collecting sputum. In addition, a door for opening and closing the placement bin 9 is provided on one side of the shell 1. When the door corresponding to the placement bin 9 is opened, the collecting bottle in the placement bin 9 can be replaced. After the collecting bottle is placed in the placement bin 9, its bottle mouth corresponds to the connection between the collecting cylinder 8 and the placement bin 9, which is conducive to collecting sputum. An annular tube 18 is provided on the top of the collecting cylinder 8, and the annular tube 18 is connected to the conveying mechanism. It should be noted that: the placement bin 9 is also provided with an elastic component for stabilizing and facilitating replacement of the collecting bottle, as well as a sealing component at the connection between the collecting bottle and the collecting cylinder 8. The specific structures of the elastic component and the sealing component are not limited, and they can be common structures on the sputum disinfection device in the prior art, and are not described in detail here.

[0032] See also Figure 1-Figure 6 Preferably, the fixing mechanism includes a fixed suction cup 13; a through hole 12 is provided at the bottom center of the shell 1, and the through hole 12 passes through the base 7, the fixed suction cup 13 is elastically arranged in the through hole 12 by a spring, and a limiting plate 25 is fixedly arranged at the connection between the shell 1 and the base 7 in the through hole 12, the spring corresponding to the fixed suction cup 13 is arranged between the fixed suction cup 13 and the limiting plate 25, and the top of the through hole 12 is fixedly connected to the transmission mechanism. When sputum needs to be collected, the cover plate 2 is opened, and the cover plate 2 is rotated to open and the transmission mechanism is moved downward through the connecting block 3, thereby causing the fixed suction cup 13 to move downward. At this time, since the shell 1 is placed on the ground, the fixed suction cup 13 moves downward and contacts the ground and completes the adsorption, thereby fixing the relative position of the entire shell 1, so that the shell 1 will not move and cause shaking when the patient coughs up sputum, thereby avoiding the problem of the shell 1 tipping over, ensuring the stability of the shell 1, and avoiding the risk of pathogen transmission.

[0033] See also Figure 1-Figure 10The top of the vertical plate 24 is kept in communication with the outside, and the cross plate 14 is kept in communication with the center of the fixed suction cup 13. A guide plate 20 is slidably provided on the top of the vertical plate 24, and the top of the guide plate 20 is slidably connected with the connecting block 3. A step-shaped structure is provided at the top opening of the vertical plate 24, and a piston block adapted to seal the channel is provided at the bottom of the guide plate 20. When the guide plate 20 moves downward, the piston block is sealed and connected to the channel at the end of the vertical plate 24 to block the end opening of the vertical plate 24. When the guide plate 20 moves upward, the piston plate leaves the end of the channel, so that the channel is kept in communication with the outside through the step-shaped structure.

[0034] Furthermore, preferably, a baffle 27 is fixedly provided on the top of the vertical plate 24, and the baffle 27 is symmetrically provided along the center of the end of the vertical plate 24. The baffle 27 is slidably fitted with the guide plate 20, so that the baffle 27 can limit the upward movement distance of the guide plate 20, thereby preventing the guide plate 20 from moving away from the vertical plate 24, and at the same time better driving the movement of the vertical plate 24. A guide groove 19 slidably connected to the top of the guide plate 20 is provided at the center of the connecting block 3, and the top of the guide plate 20 is slidably connected to the guide groove 19 through a cylindrical structure, thereby preventing the guide plate 20 from getting stuck when sliding.

[0035] Furthermore, preferably, an air guide groove 28 is provided on the bottom inner wall of the fixed suction cup 13, so that when the fixed suction cup 13 releases the limit on the outer shell 1, external air can quickly enter through the air guide groove 28, thereby avoiding the fixed suction cup 13 from being too closely fitted to the ground and failing to release the limit in time, affecting the convenience of use.

[0036] During specific use, when the cover plate 2 is in the initial state of being fitted with the shell 1, the guide plate 20 is in a position close to the cover plate 2 in the guide groove 19, the piston plate is separated from the channel opening, so that the channel opening at the end of the vertical plate 24 remains connected to the outside, and the fixed suction cup 13 shrinks in the through hole 12; when it is necessary to collect sputum, the cover plate 2 is rotated upward to open it, and the cover plate 2 is rotated upward to cause the connecting block 3 to rotate downward, and the guide plate 20 is moved downward by the action of the guide groove 19. The downward movement of the guide plate 20 will cause the piston plate to block the channel at the top of the vertical plate 24, and then the guide plate 20 pushes the vertical plate 24 to move downward, and the fixed suction cup 13 is moved downward through the cross plate 14 to extend out of the through hole 12 and contact the ground. When the cover plate 2 is kept parallel to the first fixed plate 4, the fixed suction cup 13 is completely in contact with the ground and discharges excess gas to complete the adsorption, thereby allowing The shell 1 remains fixed when collecting sputum, which improves the stability of the shell 1; when the sputum is collected, the cover plate 2 is rotated to reset and close, so that the connecting block 3 is rotated and reset, and the guide plate 20 is moved upward and reset through the guide groove 19. The upward movement of the guide plate 20 first separates the piston plate from the channel opening at the top of the vertical plate 24, so that the channel is connected to the outside, allowing external gas to enter the channel, and then the fixed suction cup 13 is brought into contact with the ground through the air guide groove 28. Subsequently, the movement of the guide plate 20 will drive the vertical plate 24 and the horizontal plate 14 to move and reset under the restriction of the baffle 27, thereby causing the fixed suction cup 13 to move and reset, and then the shell 1 can be moved freely, thereby achieving stability in the process of the shell 1 collecting sputum, and avoiding the risk of shaking or even tipping over of the shell 1 due to external reasons or when the person coughs violently.

When the piston rod 31 separates from the delivery path 16, the disinfectant in the disinfection chamber 10 enters the delivery path 16, and then the slide groove 11 moves upward through the second pull rope 26 and the L plate 15 to make the piston rod 31 move downward and extend into the delivery path 16, thereby pushing the disinfectant in the delivery path 16 to move. The end of the delivery path 16 away from the L plate 15 is fixedly connected with a connecting pipe 17. When the piston rod 31 moves and extends into the delivery path 16, the disinfectant is pushed to move toward the connecting pipe 17. The end of the connecting pipe 17 away from the delivery path 16 passes through the shell 1 and the side wall of the second fixed plate 6 and is fixedly connected to the annular tube 18. The disinfectant in the connecting pipe 17 will be sprayed into the collecting tube 8 through the annular tube 18 to disinfect the collected sputum.

A plurality of sealing plates 23 are provided in an annular array, and when opposite ends of the plurality of sealing plates 23 are fitted together, the connection between the collecting tube 8 and the placing bin 9 can be sealed. The sealing plate 23 is provided at one end of the collecting tube 8 close to the placing bin 9. A driving groove 29 is provided on the driving plate 22, and the driving plate 22 and the inner wall of the outer shell 1 are elastically connected by a spring, so that the driving plate 22 can automatically reset after being pulled and rotated, and a plurality of driving grooves 29 are provided in a circular array on the driving plate 22, and a fixing column 30 is fixedly provided on the top of the blocking plate 23, and the fixing column 30 and the driving groove 29 are slidably fitted, and the number and position of the blocking plate 23 and the driving groove 29 correspond one to one, and a first pull rope 21 is fixedly provided on the periphery of the driving plate 22, and one end of the first pull rope 21 away from the driving plate 22 slides through the side wall of the outer shell 1 and is fixedly connected to the bottom of the slide groove 11, and a wire groove for the first pull rope 21 to pass through is provided in the side wall of the outer shell 1, and the wire groove and the annular groove are connected.

[0039] When in use, in the initial state, the cover plate 2 is in a closed state, and the blocking plate 23 is in a retracted state. At this time, the collecting tube 8 and the placing bin 9 are connected, and the driving plate 22 allows the first pull rope 21 to partially enter the annular groove under the elastic action; when collecting sputum, the cover plate 2 is opened, and the cover plate 2 is rotated to open and drive the transmission mechanism to move downward through the connecting block 3. When the transmission mechanism moves downward, the driving plate 22 is pulled to rotate by the first pull rope 21.
