Description

Technical Field

[0001] This invention relates to the field of assisted expectoration technology, and in particular to an expectoration device and method. Background Technology

[0002] A medical sputum clearance device is a medical device specifically designed to help patients clear respiratory secretions and improve respiratory function, especially suitable for patients who have difficulty clearing sputum due to illness, surgery, or physical weakness.

[0003] A search revealed Chinese patent CN112043883A, which discloses a lung-clearing and sputum-expelling device for respiratory medicine, belonging to the technical field of sputum-expelling equipment. This device includes a suction tube, a negative pressure supply device, and a nebulizer. The suction tube comprises an outer tube and an inner tube disposed inside the outer tube. A silicone spiral plate is provided on the outer peripheral wall of the inner tube near the insertion end. Multiple channels communicating with the inner tube are also provided on the outer peripheral wall of the inner tube where the silicone spiral plate is located. A connecting cap is provided at the outer end of the outer tube, and a through hole is provided in the middle of the connecting cap for the inner tube to pass through. The inner tube passes through the through hole into the outer tube. The negative pressure supply device is connected to the inner tube, and the nebulizer is connected to the outer tube. This solution effectively winds the sputum around the inner tube and firmly adheres it to the outer wall of the inner tube through negative pressure. The silicone spiral plate on the inner tube not only increases the contact between the sputum and the inner tube, but also generates shear force between the sputum and the tracheal wall through the rotation of the inner tube, facilitating the separation of sputum from the trachea. However, in practical use, the above solution still has the following shortcomings: The above method does not provide lubrication for the disposable suction tube. When the disposable tube is inserted into the patient's body, it relies entirely on the patient's bodily fluids for lubrication. First, the amount of bodily fluid secretion varies from person to person and may be insufficient, especially for dehydrated, dry respiratory tract patients or patients who are fasting after surgery. In these cases, the direct insertion of a dry disposable tube will significantly increase the friction with the airway mucosa, leading to mechanical damage to the mucosal surface, causing bleeding, pain, and even local edema. This not only aggravates the patient's discomfort but may also increase the risk of infection due to mucosal damage.

[0004] Therefore, it is necessary to design a sputum expectoration device and method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sputum expectoration device and method.

[0009] As a preferred embodiment of the present invention, the rotating rod has two horizontal sections and one vertical section, the vertical section being positioned between the two horizontal sections, one of the horizontal sections being connected to a fixed frame, and the other horizontal section being rotatably mounted on a mounting frame, with the horizontal section connected to the mounting frame and the second mounting tube being coaxially arranged.

[0010] As a preferred embodiment of the present invention, the three-way valve has a connector one, a connector two, and a connector three. A connecting pipe is connected to the connector one of the three-way valve, and the end of the connecting pipe away from the three-way valve extends into the inside of the bottle. A rotary joint is provided on the connector two of the three-way valve, and the rotary joint is positioned opposite the second mounting pipe. A connecting pipe is connected to the connector three of the three-way valve, and the end of the connecting pipe away from the three-way valve is connected to a horizontal pipe.

[0011] As a preferred embodiment of the present invention, the rotating assembly is used to control the rotation of the liquid collection bottle. The rotating assembly includes a first rotating shaft and a first gear. The first rotating shaft is rotatably mounted on the side of the mounting bracket. The first gear is fixedly sleeved on the rotating rod. A second gear and a third gear are fixedly sleeved on the first rotating shaft. The second gear meshes with the first gear. The outer circumferential surface of the third gear has a notch, and there are no teeth in the notch.

[0012] In a preferred embodiment of the present invention, the extrusion assembly includes a second rotating shaft, a third rotating shaft, and a slide rod. The second rotating shaft is rotatably mounted on the side of the mounting frame. A fourth gear is sleeved on the second rotating shaft, and the fourth gear is connected to the second rotating shaft via a one-way bearing. The fourth gear meshes with the third gear. The third rotating shaft is rotatably mounted on the side of the side plate. The third rotating shaft and the second rotating shaft are connected by two meshing bevel gears. A winding wheel is fixedly sleeved on the third rotating shaft, and a pull wire is wound on the winding wheel. The winding wheel is connected to the side plate via a spring. The slide rod passes through the mounting frame and is slidably connected to the mounting frame. A push plate is fixed to one end of the slide rod, and the other end of the slide rod is connected to the pull wire. The push plate is connected to the mounting frame via a connecting spring, and the push plate is positioned opposite the baffle.

[0013] As a preferred embodiment of the present invention, a guide rail is fixed to the side of the mounting bracket, a slidable slider is provided on the guide rail, a connecting rod is fixed to the side of the slider, and a scraper ring is fixed to the end of the connecting rod away from the slider, with the scraper ring facing the rotary joint.

[0014] As a preferred embodiment of the present invention, a flow guide groove is provided on one side of the guide rail, and the flow guide groove is connected to the guide rail through a connecting plate. One end of the flow guide groove is inclined and extends into the bottle body.

[0015] A method of using a sputum expectoration device includes the following steps: Step 1: Assemble the collection bottle with the top cover using the fixing ring, ensuring that the rotating sealing ring is located between the first limiting ring and the second limiting ring, and that the top cover can rotate freely and has a good seal. Step 2: Connect one end of the disposable tubing to the second installation tube and the other end to the rotary joint. Start the suction device and use negative pressure to draw paraffin oil from the bottle through the connecting tube using the disposable tubing. Lubricate the disposable tubing and the inner wall of the pipette in sequence. Step 3: Manually rotate the rotating rod. Through the transmission of the first gear, the second gear, and the third gear, the fourth gear drives the winding wheel to wind up the cable, so that the push plate moves away from the baffle. Simultaneously start the drive unit and use centrifugal force to make the paraffin oil evenly cover the inner wall of the collection bottle. Step 4: Adjust the three-way valve to make connector 2 and connector 3 conduct. Reconnect the disposable hose to the rotary joint. Continue to rotate the rotating rod. When the notch of the third gear is aligned with the fourth gear, the winding wheel will reset under the action of the spring. The push plate will squeeze the collection bottle and press the paraffin oil into the disposable hose. The paraffin oil will be sprayed onto the outer surface of the disposable hose through the horizontal pipe spray hole. Step 5: Pull the scraper ring along the guide rail to evenly apply paraffin oil and scrape off excess oil. The excess oil flows back to the bottle through the guide channel, achieving automatic recycling. Step 6: Insert a disposable tube into the patient's mouth or nose to suction sputum. Step 7: After sputum expectoration is completed, disassemble the disposable tubing and collection bottle, and clean and disinfect the collection bottle.

[0016] The present invention has the following beneficial effects: 1. By using the bottle body, three-way valve, connecting pipe and rotary joint, before the sputum suction work, medical paraffin oil is used to flow through the disposable tubing, pipette and collection bottle to lubricate the inner wall of the pipette and collection bottle to prevent sputum from sticking and facilitate subsequent drainage and cleaning. In addition, the lubricated disposable tubing can reduce the patient's discomfort when inserted into the human body. 2. The guide rail, slider, connecting rod and scraper ring are set up so that before the disposable hose is inserted into the rotary joint, the disposable hose is passed through the scraper ring and the connecting rod is pulled to move the scraper ring. This can evenly apply paraffin oil to the surface of the disposable hose and improve the lubrication effect. The guide groove is set on one side of the guide rail and below the disposable hose. It can recover excess paraffin oil into the bottle and realize automatic recycling. 3. The top cover of the collection bottle and the bottle body are connected by a rotating sealing ring, a first limiting ring and a second limiting ring, which can achieve relative rotation and ensure sealing to prevent liquid leakage. The top cover is installed on the mounting bracket by a fixing bracket and a rotating rod. With the help of the drive unit, the collection bottle can be driven to rotate, which is convenient to operate. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figure 1-10A sputum suction device and method includes a suction device 1, a mounting frame 2 fixed to the side of the suction device 1, a baffle 22 provided on one side of the mounting frame 2, and the baffle 22 connected to the mounting frame 2 by a crossbar 21. A side plate 23 is fixed to the side of the mounting frame 2, and a liquid collection assembly is provided on the mounting frame 2 for collecting sputum. The liquid collection assembly includes a liquid collection bottle 31, such as... Figure 10 As shown, a fixing ring 33 is fixed to the mouth of the collection bottle 31, and a top cover 32 is fitted onto the fixing ring 33. The top cover 32 and the collection bottle 31 can rotate relative to each other. A first limiting ring 34 and a second limiting ring 35 are fixedly fitted onto the fixing ring 33. A rotating sealing ring 36 is provided between the first limiting ring 34 and the second limiting ring 35, and the rotating sealing ring 36 is movably fitted onto the fixing ring 33. When the top cover 32 is closed onto the fixing ring 33, the inner ring of the top cover 32 is exactly in contact with the outer circumferential surface of the rotating sealing ring 36. Since the rotating sealing ring 36 can rotate freely on the fixing ring 33, when the top cover... When the top cover 32 is fitted onto the rotating sealing ring 36, the top cover 32 can also rotate relative to the collection bottle 31. In addition, when the top cover 32 is closed on the fixing ring 33, the rotating sealing ring 36 also seals the top cover 32 and the fixing ring 33 to prevent liquid leakage. The rotating sealing ring 36 is made of rubber material, which gives it sealing performance. In addition, the upper and lower ends of the rotating sealing ring 36 are in contact with the first limiting ring 34 and the second limiting ring 35 respectively, which can prevent the rotating sealing ring 36 from shaking. A rubber sleeve 311 is fixed on the body of the collection bottle 31. A fixing frame 321 is fixed on the top cover 32. The fixing frame 321 is rotatably mounted on the side of the mounting frame 2 via a rotating rod 322. A driving part 3211 is mounted on the side of the fixing frame 321. The driving part 3211 is used to drive the collection bottle 31 to rotate. The driving part 3211 includes a bracket, a driving wheel and a motor. The bracket is mounted on the fixing frame 321, the driving wheel is rotatably mounted on the bracket, and the motor is mounted on the bracket. The output shaft of the motor is connected to the driving wheel. When the motor runs, it causes the driving wheel to rotate. The driving wheel contacts the rubber sleeve 311. When the motor drives the driving wheel to rotate, the friction between the driving wheel and the rubber sleeve 311 can drive the collection bottle 31 to rotate. As for the top cover 32, the top cover 32 is fixed by the fixing frame 321. Therefore, the collection bottle 31 can rotate relative to the top cover 32. A pipette container 41 is mounted on the top cover 32 and connected to the suction device 1. A first mounting tube 42 and a second mounting tube 43 are connected to the pipette container 41. The end of the first mounting tube 42 furthest from the pipette container 41 is connected to the top cover 32, and the end of the second mounting tube 43 furthest from the pipette container 41 is connected to a disposable tubing for suctioning sputum. When the suction device 1 is operating, the disposable tubing can draw sputum from the body into the pipette container 41. Furthermore, the suction device 1 allows the sputum in the pipette container 41 to... The sputum enters the collection bottle 31 through the first mounting tube 42, achieving active suction of the sputum. The specific structure and working principle of the suction device 1 and the transfer container 41 are existing technologies and are not shown in the figure, nor will they be elaborated upon here. The rotating rod 322 has two horizontal sections and one vertical section, with the vertical section positioned between the two horizontal sections. One horizontal section is connected to the fixing frame 321, and the other horizontal section is rotatably mounted on the mounting frame 2. The horizontal section connected to the mounting frame 2 and the second mounting tube 43 are coaxially aligned. Figure 3 As shown, when the rotating rod 322 rotates, it can drive the fixed frame 321 to rotate, which in turn drives the top cover 32 and the collection bottle 31 to rotate. When the collection bottle 31 rotates, it can rotate around the horizontal part of the rotating rod 322 that is connected to the mounting frame 2. Since the disposable hose is inserted into the second mounting tube 43, the disposable hose can rotate around the axis when the collection bottle 31 rotates. This design can prevent the disposable hose from bending or twisting when the collection bottle 31 rotates. When assisting the patient with sputum expectoration, the staff will insert a disposable tube into the second installation tube 43 and adjust the suction device 1. After the adjustment is completed, the staff will insert the disposable tube into the human body and use the suction device 1 and the transfer container 41 to suction the sputum from the patient. Finally, the sputum will be collected in the collection bottle 31. Bottle 51 is fixed on mounting bracket 2. Bottle 51 contains medical lubricant, which is medical paraffin oil. Figure 8 and Figure 9 As shown, a three-way valve 53 is provided above the bottle body 51. The three-way valve 53 has a connector one, a connector two, and a connector three. A connecting pipe 52 is connected to the connector one of the three-way valve 53. The end of the connecting pipe 52 away from the three-way valve 53 extends into the bottle body 51. A rotary connector 531 is provided on the connector two of the three-way valve 53. The sputum suction device proposed in this invention has the function of lubricating the inside of the collection bottle 31, the pipette 41, and the disposable tubing. Specifically, as... Figure 1As shown, in the initial state, the three-way valve 53 restricts the liquid from entering through connector one and flowing out through connector two. Before performing sputum suction, the operator inserts one end of the disposable tubing into the second installation tube 43, and then inserts the other end of the disposable tubing into the rotary connector 531 on connector two. Then, the suction device 1 is started. When the suction device 1 is running, it can suction liquid through the disposable tubing. At this time, under the flow-limiting effect of the three-way valve 53, the disposable tubing can draw medical paraffin oil from the bottle 51 through the connecting tube 52, and the medical paraffin oil... The medical paraffin oil is drawn into the pipette 41. Further, the suction device 1 controls the medical paraffin oil to flow into the collection bottle 31 through the first installation tube 42 until a certain amount of medical paraffin oil is accumulated inside the collection bottle 31. Preferably, when the medical paraffin oil is accumulated to one-fifth of the volume of the collection bottle 31, the staff can turn off the suction device 1. During the process of suctioning the medical paraffin oil, the medical paraffin oil will flow through the disposable tube, the pipette 41 and the collection bottle 31. During this process, the medical paraffin oil will lubricate the inner wall of the pipette 41. The mounting frame 2 is equipped with a flipping and squeezing unit, which consists of a rotating component and a squeezing component. The rotating component is used to control the rotation of the collection bottle 31. The rotating component includes a first rotating shaft 61 and a first gear 62. The first rotating shaft 61 is rotatably mounted on the side of the mounting frame 2. The first gear 62 is fixedly sleeved on the rotating rod 322. Specifically, the first rotating shaft 61 is fixed on the horizontal part connected to the mounting frame 2. A second gear 63 and a third gear 64 are fixedly sleeved on the first rotating shaft 61. The second gear 63 meshes with the first gear 62. The outer circumferential surface of the third gear 64 has a notch, and there are no teeth in the notch. The extrusion assembly includes a second rotating shaft 71, a third rotating shaft 74, and a slide rod 78. The second rotating shaft 71 is rotatably mounted on the side of the mounting frame 2. A fourth gear 72 is sleeved on the second rotating shaft 71. The fourth gear 72 is connected to the second rotating shaft 71 through a one-way bearing 73. The fourth gear 72 meshes with the third gear 64. The third rotating shaft 74 is rotatably mounted on the side of the side plate 23. The third rotating shaft 74 and the second rotating shaft 71 are connected by two meshing bevel gears. A winding wheel 75 is fixedly sleeved on the third rotating shaft 74. A pull wire 77 is wound on the winding wheel 75. The winding wheel 75 is connected to the side plate 23 through a spring 76. The slide rod 78 passes through the mounting frame 2 and is slidably connected to the mounting frame 2. A push plate 79 is fixed to one end of the slide rod 78. The other end of the slide rod 78 is connected to the pull wire 77. The push plate 79 is connected to the mounting frame 2 through a connecting spring 710. The push plate 79 is positioned opposite the baffle 22. After a certain amount of paraffin oil accumulates inside the collecting bottle 31, the operator turns the handle on the rotating rod 322, causing the rod to rotate. When the rod rotates, the first gear 62 on it rotates accordingly. The rotation of the first gear 62 drives the meshing second gear 63 to rotate, which in turn drives the first rotating shaft 61 to rotate. The third gear 64 on the first rotating shaft 61 then rotates, further driving the fourth gear 72 to rotate. This causes the second rotating shaft 71 to rotate. The second and third rotating shafts 71 are connected by two meshing bevel gears, so the rotation of the second shaft 71 drives the rotation of the third shaft 74, ultimately causing the winding wheel 75 to rotate. The rotation of the winding wheel 75 then winds up the wire 7. 7. This causes the pull wire 77 to pull the slide bar 78, which in turn causes the slide bar 78 to move the push plate 79. Therefore, while the rotating rod 322 drives the top cover 32 to rotate through the fixed frame 321, the push plate 79 can move synchronously away from the baffle 22. During this process, the distance between the push plate 79 and the baffle 22 will increase, so that the collection bottle 31 can rotate between the push plate 79 and the baffle 22. As for the collection bottle 31, during the rotation under the action of the rotating rod 322, it will also rotate at high speed under the action of the drive unit 3211. At this time, the paraffin oil inside the collection bottle 31 will flow towards the top cover 32 under the action of gravity, and at the same time, under the action of the centrifugal force of high speed rotation, it will evenly cover the inner wall of the collection bottle 31, achieving full lubrication of the inner wall of the collection bottle 31. A horizontal pipe 54 is fixed on the side of the baffle 22. The horizontal pipe 54 is connected to the connector of the three-way valve 53 through a connecting pipe 55. Several spray holes are opened on the horizontal pipe 54. When the disposable hose is inserted between the second mounting pipe 43 and the rotary joint 531, the disposable hose is located directly below the horizontal pipe 54. When the collection bottle 31 rotates 180°, the top cover 32 faces downwards. At this point, the operator stops rotating the rotating rod 322. In this situation, the notch on the third gear 64 rotates to a position close to the fourth gear 72. The third gear 64 remains engaged with the fourth gear 72. Next, the operator closes the drive unit 3211, stopping the collection bottle 31 from rotating. When the collection bottle 31 stops rotating, the paraffin oil inside the collection bottle 31 accumulates inside the top cover 32. Then, the operator adjusts the three-way valve 53 to connect connector two and connector three. At this point, the liquid can only enter the connecting pipe 55 through the disposable hose, and finally enter the horizontal pipe 54 through the connecting pipe 55. After adjusting the three-way valve 53, the operator continues to rotate the handwheel, causing the first rotating shaft 61 to drive the third gear 64 to rotate. When the third gear 64 rotates, its notch position rotates to face the fourth gear 72. At position 2, since there are no teeth at the notch, the third gear 64 and the fourth gear 72 no longer mesh. Without the constraint of the third gear 64, the second shaft 71 can rotate freely. At this time, the winding wheel 75 will be reset under the action of the spring 76, and the push plate 79 will also be reset under the action of the connecting spring 710. When the push plate 79 is reset, it will squeeze the collection bottle 31. The collection bottle 31 is made of soft plastic material. Therefore, when the collection bottle 31 is squeezed by the push plate 79, the collection bottle 31 will deform. Furthermore, the paraffin oil inside the collection bottle 31 is squeezed and deformed by the collection bottle 31 and is forced into the disposable hose. Finally, it enters the horizontal tube 54 through the connecting tube 55. The horizontal tube 54 has several spray holes. The paraffin oil will flow out through several spray holes and flow to the outer surface of the disposable hose, thereby lubricating the outer surface of the disposable hose. A guide rail 81 is fixed to the side of the mounting bracket 2. A sliding slider 82 is mounted on the guide rail 81. A connecting rod 83 is fixed to the side of the slider 82. A scraper ring 84 is fixed to the end of the connecting rod 83 away from the slider 82. Before the operator inserts the disposable hose into the rotary joint 531, the operator can pass the disposable hose through the scraper ring 84. When the paraffin oil flows onto the outer surface of the disposable hose, the operator pulls the connecting rod 83, causing the connecting rod 83 to move the scraper ring 84 until the scraper ring 84 moves from one end of the disposable hose to the other end. During this process, the scraper ring 84 can evenly coat the surface of the disposable hose with paraffin oil, thereby improving the lubrication effect on the disposable hose. Furthermore, a guide groove is also provided on one side of the guide rail 81. The guide groove is fixed to the guide rail 81 by a connecting plate, and the guide groove is located below the disposable hose. When the scraper ring 84 scrapes the paraffin oil, excess paraffin oil will drip onto the guide groove. Figure 7 As shown, one end of the guide channel extends into the bottle body 51, so excess paraffin oil will flow back into the bottle body 51 along the guide channel, realizing the automatic recycling of paraffin oil. It is worth noting that the fourth gear 72 is mounted on the second rotating shaft 71 via a one-way bearing 73. When the operator controls the collection bottle 31 to flip from bottom to top, the third gear 64 drives the fourth gear 72 to rotate in the forward direction. At this time, the fourth gear 72 can drive the second rotating shaft 71 to rotate via the one-way bearing 73. When the operator controls the collection bottle 31 to reset from top to bottom, the third gear 64 drives the fourth gear 72 to rotate in the reverse direction. At this time, under the action of the one-way bearing 73, the fourth gear 72 will not drive the second rotating shaft 71 to rotate. This design can prevent the winding wheel 75 from rotating when the collection bottle 31 is reset, so that the push plate 79 can squeeze the collection bottle 31 next time. In summary, the sputum drainage device proposed in this invention not only lubricates the interior of the collection bottle 31 and the pipette container 41, but also lubricates the outer surface of the disposable tubing. When the lubricated disposable tubing is inserted into the human body, it will reduce the patient's discomfort and avoid causing additional harm. The lubricated collection bottle 31 and the pipette container 41 can prevent sputum from adhering to the inner walls of the collection bottle 31 and the pipette container 41, and facilitate the subsequent drainage and cleaning of the collection bottle 31 by the staff.
