Description

Technical Field

[0001] The present invention relates to the technical field of medical respiratory tract cleaning instruments, and particularly to a respiratory tract cleaning device for the care of critically ill patients. Background Art

[0002] The respiratory tract is the passage through which air flows during lung respiration. The respiratory tract is divided into two parts: the upper and lower respiratory tracts. The nose, pharynx, and larynx are collectively called the upper respiratory tract. The trachea, bronchi, and lung organs are collectively called the lower respiratory tract, or the tracheal tree. The tracheal tree has become gradually more complex with the evolution of animals. The so-called upper respiratory tract refers to the air passage from the nose to the throat. If the air is blocked or rubbed when passing through this passage, it will cause snoring. People who often snore usually either have a congenitally narrow upper respiratory tract, a too long tongue, or have nasal diseases with frequent blockage of nasal mucus and secretions.

[0003] Respiratory diseases are one of the common diseases in clinical practice. Many severely ill patients need doctors to actively clean the patient's respiratory tract when suffering from respiratory diseases. The common cleaning method is to perform sputum suction.

[0004] In the prior art, a Chinese invention patent with the application publication number CN115154699A discloses a respiratory tract cleaning device for the care of critically ill patients, which relates to the field of respiratory tract cleaning. It includes an outer housing. A sputum suction tube is provided at the upper end of the outer housing. A biting device is provided on the sputum suction tube. The biting device includes an annular plate. The annular plate is sleeved on the outside of the sputum suction tube. A biting plate is provided on the annular plate. There are two biting plates in total, and the two biting plates are symmetrically arranged on both sides of the annular plate. An inner housing is provided inside the outer housing. The described respiratory tract cleaning device for the care of critically ill patients can timely process the absorbed sputum, effectively prevent the absorbed sputum from polluting the surrounding environment, and at the same time reduce the subsequent sputum processing process, simplify the work content. At the same time, when this device is used on patients, the patient's biting can feel comfortable, which is convenient for the operation of sputum suction.

[0005] Problems compared with the prior art: Some of the existing respiratory tract cleaning devices for the care of critically ill patients cannot stably support and fix the heads of critically ill patients, and cannot properly clean the thick sputum adhering to the inner wall of the respiratory tract of critically ill patients, resulting in the difficulty of ensuring the cleaning effect of the respiratory tract of critically ill patients.

[0006] Therefore, there is an urgent need for a respiratory tract cleaning device for the care of critically ill patients. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a respiratory tract cleaning device for the care of critically ill patients.

The adjustment mechanism includes a leg, which is welded above the base. A lifting rod is provided on the inner wall of the leg, and a side plate is fixedly connected to the inner wall of the lifting rod. The side plate is fixedly connected to the top of the elastic airbag. One end of the lifting rod is fixedly connected to a limit frame, and a lead screw is provided at the middle position of the limit frame. A push rod is provided on the outer side of the lead screw, and a clamping plate is fixedly connected to one end of the push rod.

[0012] As a further solution of the present invention: The control tube is fixed to the middle position of the sputum suction tube by bolts.

[0039] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Embodiment 1:

[0041] As Figure 1-8As shown in the figure, a respiratory tract cleaning device for the care of critically ill patients includes a base 100, a collection tank 200 installed at one end of the base 100, a sputum suction tube 300 installed above the collection tank 200, and a cleaning mechanism arranged inside the sputum suction tube 300 for cleaning the respiratory tract of critically ill patients. A telescopic tube 400 is fixed in the middle position of the sputum suction tube 300 by bolts. A holding sleeve 500 is pasted at one end of the sputum suction tube 300. A negative pressure pump 600 is fixed at the other end of the sputum suction tube 300 by bolts. The cleaning mechanism includes a control tube 101, a rotating cylinder 102, a T-shaped tube 104, an extension rod 106, a scraper 107, and an elastic airbag 109. The scraper 107 is made of food-grade silicone material. One end of the control tube 101 is communicated with the elastic airbag 109, and the other end of the control tube 101 is rotationally communicated with the rotating cylinder 102. The T-shaped tube 104 slides along the inner wall of the rotating cylinder 102. The T-shaped tube 104 extends out of the rotating cylinder 102 to clean the respiratory tract of critically ill patients, and the T-shaped tube 104 retracts into the rotating cylinder 102 to store the scraper 107. The extension rod 106 is slidably connected to both ends of the T-shaped tube 104. The scraper 107 is fixed to one end of the extension rod 106 by bolts. When the extension rod 106 extends along the T-shaped tube 104, the scraper 107 is close to the respiratory tract of critically ill patients. When the extension rod 106 retracts along the T-shaped tube 104, the scrapers 107 approach each other and are away from the respiratory tract of critically ill patients. The control tube 101 is fixed in the middle position of the sputum suction tube 300 by bolts. One end of the control tube 101 is fixed with a rotating connector 110 by bolts. The rotating cylinder 102 is rotatably connected to one end of the control tube 101. A piston plate A 103 is frictionally connected to the inner wall of the rotating cylinder 102. The T-shaped tube 104 is fixed to the middle position of the piston plate A 103 by bolts. Piston plates B 105 are frictionally connected to both ends of the T-shaped tube 104. The extension rod 106 is fixed to the middle position of the piston plate B 105 by bolts. A camera 108 is fixed to the outer wall of the T-shaped tube 104 to observe the respiratory tract of critically ill patients through the camera 108. The elastic airbag 109 is fixed above the base 100 by bolts. An electric valve A 120 is fixed to the middle position of the piston plate A 103 by bolts, and the electric valve A 120 controls the piston plate A 103 to be closed or opened. Pressure relief valves 130 are fixed to both sides of the T-shaped tube 104 to relieve pressure on the piston plate B 105 through the pressure relief valves 130 to prevent the distance between the scrapers 107 from being too large and squeezing the respiratory tract of critically ill patients. An electric valve B 140 is fixed to one side of the control tube 101 by bolts, and the electric valve B 140 controls the control tube 101 to be communicated or closed.

[0042] It also includes a support mechanism arranged on both sides of the elastic airbag 109 for supporting and fixing the head of critically ill patients. The support mechanism includes a connecting pipe 301, a splint 303, and a telescopic airbag 304. The connecting pipe 301 is fixedly connected to both ends of the elastic airbag 109. One end of the connecting pipe 301 is elastically communicated with the telescopic airbag 304 to ensure that the connecting pipe 301 can still be communicated when the telescopic airbag 304 moves up and down. The telescopic airbag 304 is fixed to the inner wall of the splint 303 by bolts. An electric valve C302 is fixed to one side of the connecting pipe 301 by bolts, and the electric valve C302 controls the intake or exhaust of the telescopic airbag 304. A sponge pad 305 is pasted on one end of the telescopic airbag 304, and the sponge pad 305 contacts the head of the critically ill patient. A telescopic protective cover 306 is fixed to the outside of the splint 303 by bolts, and one end of the telescopic protective cover 306 is fixedly connected to the sponge pad 305 to limit the telescopic trajectory of the telescopic airbag 304 through the telescopic protective cover 306.

[0043] It also includes a mounting mechanism arranged outside the collection tank 200 for quickly disassembling and assembling the collection tank 200. The mounting mechanism includes a spiral spring 501, a pull rod 506, a damping hinge 505, and a pressing frame 504. The movable end of the spiral spring 501 and one end of the pull rod 506 are on the same horizontal plane. The damping hinge 505 dampingly connects the pull rod 506 and the pressing frame 504. The pressing frame 504 is L-shaped, and the number of the pressing frames 504 is 3 and they are evenly distributed along the circumference outside the collection tank 200 to ensure the installation stability of the collection tank 200. The spiral spring 501 is fixed to the lower part of the base 100 by bolts. One end of the spiral spring 501 is fixed to a bottom plate 502 by bolts. The pull rod 506 is welded above the bottom plate 502. The damping hinge 505 is fixed to one end of the pull rod 506 by bolts. The pressing frame 504 is fixed to one end of the damping hinge 505 by bolts. The outside of the pull rod 506 is slidably connected to a frame 503, and the pressing frame 504 is slidably connected to the frame 503. When the pull rod 506 rises, the pressing frame 504 extends out of the frame 503, and the pressing frame 504 rotates along the damping hinge 505 to disassemble the collection tank 200. When the pull rod 506 descends, the pressing frame 504 retracts into the frame 503, and the pressing frame 504 and the middle section of the frame 503 are in the same vertical plane to install the collection tank 200.

[0044] In this embodiment, the head of a critically ill patient is supported by the elastic airbag 109. The gravity of the head of the critically ill patient presses on the elastic airbag 109, forcing the gas in the elastic airbag 109 into the connecting pipe 301, thereby inflating the telescopic airbag 304. The sponge pad 305 stably supports and fixes the head of the critically ill patient. At the same time, high-pressure gas can push the piston plate A 103 and the piston plate B 105 through the control pipe 101. The piston plate A 103 drives the scraper 107 to insert into the respiratory tract of the critically ill patient, and the piston plate B 105 drives the scraper 107 to closely adhere to the inner wall of the respiratory tract of the critically ill patient. Driven by the driving mechanism, the scraper 107 scrapes the thick sputum adhering to the inner wall of the respiratory tract of the critically ill patient, ensuring the cleaning effect of the respiratory tract of the critically ill patient.

[0045] When this embodiment is in use, the critically ill patient first lies on the elastic airbag 109. The elastic airbag 109 is pressed during the lying process of the critically ill patient. The electric valve C 302 is controlled to open, and high-pressure gas enters the telescopic airbag 304. The telescopic airbag 304 drives the sponge pads 305 to approach each other, squeezing the two sides of the head of the critically ill patient. Subsequently, the electric valve C 302 is closed. When cleaning the respiratory tract of the critically ill patient, the electric valve B 140 is opened, and high-pressure gas enters the control pipe 101. The high-pressure gas can push the piston plate A 103 and the piston plate B 105 through the control pipe 101. The piston plate A 103 drives the scraper 107 to insert into the respiratory tract of the critically ill patient, and the piston plate B 105 drives the scraper 107 to closely adhere to the inner wall of the respiratory tract of the critically ill patient. The electric valve B 140 is closed, and driven by the driving mechanism, the scraper 107 rotates to scrape the thick sputum adhering to the inner wall of the respiratory tract of the critically ill patient.

The air holes (220) and the rotary drum 102 are both at an angle of 45° to the horizontal plane, ensuring that the wind force is fully utilized. One end of the air inlet pipe 201 is fixed with an air filter 210 by bolts, and the air filter 210 purifies the air.

[0048] An adjustment mechanism is provided on the outer side of the elastic airbag 109 for adjusting the support spacing of the support mechanism. The adjustment mechanism includes a leg 401 welded above the base 100. A lifting rod 403 is slidably connected to the inner wall of the leg 401. A side plate 402 is fixed to the inner wall of the lifting rod 403 by bolts, and the side plate 402 is fixedly connected to the top of the elastic airbag 109 to ensure that the lifting rod 403 moves synchronously with the elastic airbag 109. One end of the lifting rod 403 is fixed with a limit frame 404 by bolts. A lead screw 405 is rotatably connected to the middle position of the limit frame 404. A push rod 406 is drivingly connected to the outer side of the lead screw 405. When the lead screw 405 rotates, it drives the push rod 406 to move horizontally. A clamping plate 303 is fixedly connected to one end of the push rod 406. A support plate 700 is fixed to the outer side of the base 100 by bolts, and the support plate 700 limits the expansion direction of the elastic airbag 109. An inner concave pad 800 is fixed to the top of the elastic airbag 109 by bolts, and the inner concave pad 800 ensures the safety during the respiratory tract cleaning process of critically ill patients. A plurality of mounting brackets 900 are fixed to the lower part of the base 100 by bolts, and the respiratory tract cleaning device for the care of critically ill patients is fixed to the hospital bed through the mounting brackets 900.

[0049] In this embodiment, the air is pressurized by the booster pump 202, and the high-pressure gas pushes the turbofan 204 to rotate, thereby driving the rotating cylinder 102 to rotate self - sufficiently. The rotating cylinder 102 drives the T - shaped tube 104 to rotate self - sufficiently. The T - shaped tube 104 drives the scraper 107 to rotate to clean the respiratory tract of critically ill patients. By rotating the lead screw 405, the lead screw 405 drives the push rod 406 to move horizontally, thereby driving the clamping plate 303 to approach or move away, so that the respiratory tract cleaning device for the care of critically ill patients can meet the needs of patients with different head circumferences, enriching the functionality of the respiratory tract cleaning device for the care of critically ill patients.

[0050] When this embodiment is in use, the booster pump 202 is driven, and the high - pressure gas pushes the turbofan 204 to rotate, thereby driving the rotating cylinder 102 to rotate self - sufficiently. The rotating cylinder 102 drives the T - shaped tube 104 to rotate self - sufficiently. The T - shaped tube 104 drives the scraper 107 to rotate to clean the respiratory tract of critically ill patients. The negative pressure pump 600 pumps the cleaned sputum into the collection tank 200.
