Description

Technical Field

[0001] The present invention belongs to the technical field of respiratory equipment. Specifically, it particularly relates to a sputum crust remover. Background Art

[0002] A sputum crust refers to a hard lump formed by the condensation of secretions after the throat, trachea, or bronchus is stimulated by inflammation. It is usually accompanied by symptoms such as coughing and acute infection and needs to be treated in a timely manner to avoid the aggravation of the condition. Methods for treating sputum crusts include drinking plenty of water, coughing, back patting, oxygen inhalation, etc. If the condition is severe, drug treatment can be considered; while a sputum crust remover is a medical device mainly used to remove sputum and sputum crusts attached to the respiratory tract. The design of this device aims to help solve the problem of the trachea being blocked by the crusting of respiratory secretions. Especially during medical procedures such as tracheal intubation, when the moisture of the lower respiratory tract secretions evaporates relatively quickly and it is easy to form thick sputum attached to the tracheal wall, the sputum crust remover becomes particularly important. It can effectively soften, scrape, and suck out the sputum crust, thereby reducing the pain of the patient and improving the treatment efficiency.

[0003] The traditional sputum crust remover is to manually insert a suction tube into the patient's trachea for auxiliary removal. When the traditional sputum crust remover is removing, it is easy for sputum crusts to remain on the inner wall of the trachea, and it is necessary to manually control the suction tube for multiple removals, resulting in low removal efficiency and poor removal effect. When the suction tube is inserted into the patient's trachea, when the suction tube reaches a sensitive position in the patient's trachea, it is easy to stimulate the patient's oral cavity to suddenly close, affecting the removal process, and in severe cases, it may cause damage to the patient's body. Summary of the Invention

[0004] In view of the problems in the related art, the present invention provides a sputum crust remover to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention provides a sputum crust remover, including a connecting tube. The connecting tube is rotatably installed with an insertion tube. The insertion tube is fixedly installed with a suction head. The insertion tube is fixedly installed with a scraper. The scraper is located between the suction head and the connecting tube. The insertion tube is fixedly installed with a first gear. The first gear meshes with a second gear. The second gear is fixedly installed on the output shaft of a micro motor. The insertion tube is rotatably installed with a connecting plate. The connecting plate is provided with an expansion mechanism. The expansion mechanism includes a fixing plate arranged on the connecting plate. The fixing plate is fixedly installed with an arc-shaped expansion plate through a return spring;

[0007] Medical staff first insert the insertion tube into the patient's trachea and move it to the designated position. Subsequently, the micro motor is started, and the output shaft of the micro motor drives the second gear to rotate. Through the meshing first gear, the insertion tube and the scraper rotate accordingly, effectively scraping off the respiratory tract sputum crusts, rapidly reducing sputum accumulation. After inserting into the trachea, the medical staff adjust the position of the connecting plate, insert the arc-shaped expansion plate into the patient's mouth, and utilize the reaction force of the return spring to make the arc-shaped expansion plate move towards the fixed plate, expanding and supporting the mouth, playing a supporting role to prevent the trachea from being stimulated and closed.

[0008] Further, the connecting tube, the insertion tube and the suction head are interconnected with each other. The scraper is made of silica gel material, and the arc-shaped expansion plate is made of rubber material.

[0009] Further, the micro motor is fixedly installed on the connecting tube, the fixed plate is fixedly installed on the connecting plate, one end of the return spring is fixedly installed on the fixed plate, and the other end is fixedly installed on the arc-shaped expansion plate. The return spring has a force tending to reset towards the fixed plate. There are two groups of expansion mechanisms, and their parts and installation methods are the same.

[0010] Further, a sputum crust carrier cylinder is movably installed below the connecting tube, and the sputum crust carrier cylinder is interconnected with the connecting tube.

[0011] Further, the connecting tube is threadedly connected with a connecting piece. The connecting piece is fixedly installed on the air cylinder. One end of the connecting piece is movably installed with a filter screen, and the other end is movably installed with a one-way valve.

[0012] Further, the connecting tube is interconnected with the connecting piece, and the connecting piece is interconnected with the air cylinder through the one-way valve.

[0013] Further, a piston is slidably connected inside the air cylinder. One end of the piston is fixedly installed with a piston rod, and the other end of the piston rod is fixedly installed with a control handle.

[0014] Further, a grip is fixedly installed at one end of the air cylinder close to the control handle. The air cylinder is provided with ventilation holes, and the ventilation holes are movably installed with sealing plugs.

[0015] Further, one end of the insertion tube can be externally connected to a connecting hose, and the other end of the hose is fixedly connected to the inside of a liquid storage cylinder.

[0016] The present invention has the following beneficial effects compared with the prior art:

[0017] 1. The phlegm crust remover proposed by the present invention drives the scraper to rotate through a micro motor, effectively scraping off the phlegm crust attached to the respiratory tract, rapidly reducing the accumulation of phlegm. The scraper is made of silica gel material, reducing the friction and discomfort to the respiratory tract and reducing the pain of patients. At the same time, using the negative pressure generated by the air cylinder, the phlegm crust is sucked in through the suction head and automatically discharged into the phlegm crust bearing cylinder, with simple and efficient operation.

[0018] 2. The expansion mechanism designed by the present invention inserts the arc-shaped expansion plate into the patient's mouth position through the reaction force of the return spring, playing a supporting role to prevent the trachea from being stimulated and closed, ensuring the smooth insertion of the insertion tube. The design of two groups of expansion mechanisms can simultaneously expand the upper and lower positions of the patient's mouth, not only improving the convenience of operation, but also reducing the workload of medical staff and improving work efficiency.

[0019] 3. The present invention not only has the function of removing phlegm crust, but also through the design of the liquid storage cylinder and the hose, can transport physiological saline into the insertion tube, spray out through the suction head to contact the phlegm crust, play a dilution role, make the phlegm crust fade, and be more easily removed. In addition, the connecting pipe and the connector are connected by threads, which is convenient for disassembly and cleaning, increasing the practicability and durability of the equipment. At the same time, the design of the air vent and the sealing plug allows the air inside the air cylinder to be discharged when repeatedly sucking the phlegm crust, ensuring the smooth progress of the operation.

[0020] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the invention.

[0032] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the invention.

[0033] Please refer to Figures 1 - 7 As shown, the present invention is a sputum crust remover, including a connecting pipe 1, an insertion pipe 2 rotatably installed on the connecting pipe 1, a suction head 3 fixedly installed on the insertion pipe 2, a scraper 4 fixedly installed on the insertion pipe 2, the scraper 4 being located between the suction head 3 and the connecting pipe 1, a first gear 5 fixedly installed on the insertion pipe 2, a second gear 6 meshing with the first gear 5, the second gear 6 fixedly installed on the output shaft of a micro motor 7, a connecting plate 8 rotatably installed on the insertion pipe 2, the connecting plate 8 being provided with an expanding mechanism, and the expanding mechanism including a fixed plate 9 provided on the connecting plate 8, and an arc-shaped expanding plate 11 fixedly installed on the fixed plate 9 through a return spring 10.

[0034] The working principle of a sputum crust remover proposed by the present invention is that when the present invention is used to remove sputum crusts, first, medical staff insert the insertion tube 2 into the patient's trachea and move it to the designated position, then start the micro motor 7. The output shaft of the micro motor 7 drives the second gear 6 to rotate. Since the second gear 6 meshes with the first gear 5, the first gear 5 is driven to rotate, and then the insertion tube 2 is driven to rotate, thereby driving the scraper 4 to rotate. Thus, the sputum crusts attached to the respiratory tract can be effectively scraped off, and the accumulation of sputum on the respiratory tract can be rapidly reduced.

[0035] It should be noted that after the hospital staff insert the insertion tube 2 into the patient's trachea, the medical staff adjust the position of the connecting plate 8 on the insertion tube 2, then insert the arc-shaped expanding plate 11 into the patient's mouth position, and then use the reaction force of the return spring 10 to drive the arc-shaped expanding plate 11 to move towards the fixed plate 9, thereby expanding the patient's mouth position and playing a supporting role to prevent the problem that the patient's trachea is stimulated and closed.

[0036] In one embodiment, for the above-mentioned connecting tube 1, the connecting tube 1, the insertion tube 2 and the suction head 3 are interconnected. The scraper 4 is made of silica gel material, and the arc-shaped expanding plate 11 is made of rubber material.

[0037] The working principle of a sputum crust remover proposed by the present invention is that the scraper 4 is made of silica gel material, which can reduce the friction and discomfort on the respiratory tract, thereby reducing the pain of the patient. And the arc-shaped expanding plate 11 is made of rubber material, which can reduce the discomfort generated when the patient's mouth is expanded.

[0038] In one embodiment, for the above-mentioned micro motor 7, the micro motor 7 is fixedly installed on the connecting tube 1, the fixed plate 9 is fixedly installed on the connecting plate 8, one end of the return spring 10 is fixedly installed on the fixed plate 9, and the other end is fixedly installed on the arc-shaped expanding plate 11. The return spring 10 has a force tending to reset towards the fixed plate 9. There are two sets of expanding mechanisms, and their parts and installation methods are the same.

[0039] The working principle of a sputum crust remover proposed by the present invention is that by setting two sets of expanding mechanisms, the patient's mouth can be expanded simultaneously from top to bottom, which not only avoids the problem that the patient's trachea is stimulated and closed, but also ensures the smooth insertion of the insertion tube 2, reduces the workload of medical staff, and improves work efficiency.

[0040] In one embodiment, for the above-mentioned connecting tube 1, a sputum crust carrier tube 12 is movably installed below the connecting tube 1, and the sputum crust carrier tube 12 is interconnected with the connecting tube 1.

[0041] In one embodiment, for the above-mentioned connecting pipe 1, the connecting pipe 1 is threadedly connected with a connector 13, the connector 13 is fixedly installed on the air cylinder 14, a filter net 15 is movably installed at one end of the connector 13, and a check valve 16 is movably installed at the other end.

[0042] In one embodiment, for the above-mentioned connecting pipe 1, the connecting pipe 1 communicates with the connector 13, and the connector 13 communicates with the air cylinder 14 through the check valve 16.

[0043] In one embodiment, for the above-mentioned air cylinder 14, a piston 17 is slidably connected inside the air cylinder 14. One end of a piston rod 18 is fixedly installed on the piston 17, and a control handle 19 is fixedly installed at the other end of the piston rod 18.

[0044] The working principle of a phlegm crust remover proposed by the present invention is that after the above-mentioned preparatory work is completed, hospital staff pull the control handle 19, thereby driving the piston rod 18 to move away from the air cylinder 14, and then driving the piston 17 to move, so that a negative pressure is generated inside the air cylinder 14, and then the phlegm crust in the patient's trachea is sucked into the inside of the insertion tube 2 through the suction head 3, and then flows into the inside of the connecting pipe 1, and then is automatically sucked into the phlegm crust bearing cylinder 12.

[0045] It should be noted that during the above operation, the check valve 16 is in an open state, and the filter net 15 can block the phlegm crust inside the connecting pipe 1 to prevent it from being sucked into the air cylinder 14.

[0046] Furthermore, when the connecting pipe 1 needs to be cleaned, since the connecting pipe 1 and the connector 13 are threadedly connected, only by rotating the connecting pipe 1 can it be removed for cleaning, which greatly saves the workload and improves the work efficiency.

[0047] In one embodiment, for the above-mentioned air cylinder 14, a grip 20 is fixedly installed at one end of the air cylinder 14 close to the control handle 19. The air cylinder 14 is provided with a ventilation hole 21, and a sealing plug 22 is movably installed in the ventilation hole 21.

[0048] The working principle of a phlegm crust remover proposed by the present invention is that when it is necessary to repeatedly suck the phlegm crust of the patient, the sealing plug 22 is pulled out from the inside of the ventilation hole 21, and the piston rod 18 is pushed forward to move the piston 17 from the rear end to the front end of the inner cavity of the air cylinder 14. During this process, the check valve 16 is in a closed state to prevent the insertion tube 2 from blowing air into the patient's trachea. The air inside the air cylinder 14 flows out of the air cylinder 14 through the ventilation hole 21. After the piston 17 moves to the front end of the inner cavity of the air cylinder 14, the above operation is reversed to extract the phlegm crust again to complete the extraction operation of the phlegm crust.

[0049] In one embodiment, for the above-mentioned insertion tube 2, the insertion tube 2 can be externally connected to one end of a connecting hose 23, and the other end of the hose 23 is fixedly connected to the inside of a liquid storage cylinder 24.

[0050] The working principle of a phlegm crust remover proposed by the present invention is that physiological saline can be transported through the hose 23 to the inside of the insertion tube 2 by the liquid storage cylinder 24, and then sprayed out by the suction head 3 to the throat of the patient to contact the phlegm crust, playing a role in diluting the phlegm crust, making the phlegm crust fade, which is beneficial to removal.
