Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to an oral foreign body cleaning device for critically ill patients. Background Art
[0002] During intensive care, patients often cannot expel oral foreign bodies through the body's own reflexes due to coma, loss of consciousness, or the limitations of respiratory support equipment. At this time, medical staff need to clean the secretions and impurities in their oral cavities in a timely manner. However, due to the complex oral cavity structure and the tongue's tendency to collapse and block the airway, it is difficult to complete the cleaning relying solely on manual operations.
[0003] The oral foreign body cleaning device for critically ill patients is a medical auxiliary instrument used to clean the foreign bodies in the oral cavities of critically ill patients. It can remove the secretions, vomitus, or other impurities in the patient's oral cavity that may affect the patency of the respiratory tract, ensure the patency of the patient's airway, and reduce the risk of asphyxiation or infection. When the patient is unable to cooperate with oral care operations due to the illness, the cleaning device is particularly important. It can not only effectively assist the nursing staff to complete the cleaning work, but also reduce the health risks brought by the accumulation of foreign bodies to the patient.
[0004] However, in the use of the existing oral foreign body cleaning devices for critically ill patients, a tongue depressor is needed to control the position of the tongue. However, due to the softness of the tongue and its susceptibility to the influence of gravity and position changes, it is difficult to accurately fix the tongue with the tongue depressor, resulting in frequent collapse of the tongue, which in turn blocks or obstructs the throat. This not only increases the difficulty of foreign body cleaning, but also may further endanger the patient's respiratory safety. Moreover, the interference caused by the unstable position of the tongue will reduce the cleaning efficiency and may even lead to incomplete cleaning due to blocked vision, and the respiratory problems of the patient cannot be completely solved.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the specification of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0034] In order to better understand the present invention, the above content will be described in detail below in conjunction with specific embodiments
[0035] Please refer to the attached Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9 , an oral foreign body cleaning device for critically ill patients provided by an embodiment of the present invention is characterized in that it includes: a bracket 1, the bottom of which is connected with a support block 2, and both the bracket 1 and the support block 2 are provided with two. The two brackets 1 are connected by an upper arc rod 20, and the two support blocks 2 are connected by a lower arc rod 21; a support rod 3, the end of which is connected with a snap ring 4, and the support rod 3 is installed on both sides of the middle of one side of the bracket 1 and the support block 2 for clamping the upper and lower rows of teeth; a straw 5, which is movably connected to one side of the lower arc rod 21, one end of which communicates with a suction cylinder 6, and the other end communicates with a connecting pipe 7. One end of the connecting pipe 7 communicates with an airbag 8, and one side of the middle of the connecting pipe 7 communicates with an exhaust pipe 9. A check valve one 10 is installed in the exhaust pipe 9, a check valve two 11 is installed in the middle of the connecting pipe 7, and the airbag 8 is used to discharge the air in the connecting pipe 7 when pressed, and suck the air in the straw 5 and the suction cylinder 6 after recovery, so that a negative pressure is generated in the suction cylinder 6 to suck the tongue.
[0036] In the present invention, a stable structure can be formed between the bracket 1, the support block 2, the upper arc rod 20 and the lower arc rod 21 and placed in the patient's mouth. The retainer ring 4 is used to engage the upper and lower rows of teeth of the patient, so that the device can be fixed in the patient's mouth and keep the oral cavity in an open state. Then, the air in the connecting tube 7 is discharged by pressing the air bag 8, and the air in the suction cylinder 6 and the suction tube 5 is sucked after release to form a negative pressure, thereby adsorbing the patient's tongue. At the same time, the excess gas is discharged through the one-way valve 10 of the air outlet pipe 9 to prevent backflow, and the one-way valve 11 further improves the sealing performance of the system to avoid the negative pressure effect being damaged due to gas backflow. In this way, the patient's tongue can be fixed in the suction cylinder 6. By restricting the position of the tongue, it can be avoided that the tongue collapses and blocks the throat or airway, thereby causing obstruction or blockage, resulting in limited operating space for medical staff and affecting the removal of foreign bodies.
[0037] Please refer to the attached Figure 1 , Figure 3 , Figure 4 and Figure 5 , and the middle part of the other side of the connecting tube 7 is communicated with a pressure relief tube 12, and a valve 13 is installed in the pressure relief tube 12.
[0038] During use, closing the valve 13 can prevent the air inside the suction tube 5 from entering and exiting through the pressure relief tube 12. After use, opening the valve 13 allows external gas to enter the suction tube 5 and the suction cylinder 6. Therefore, the negative pressure environment inside the suction cylinder 6 can be removed, and then the suction cylinder 6 can be separated from the patient's tongue.
[0039] Please refer to the attached Figure 1 , Figure 3 and Figure 4 , and a collection bottle 14 is provided between the connecting tube 7 and the suction tube 5. The connecting tube 7 is movably connected to the collection bottle 14. The bottom of the collection bottle 14 is movably connected to a sealing cover 15, and one end of the suction tube 5 is at the inner bottom on one side of the collection bottle 14, and one end of the connecting tube 7 is at the inner top on one side of the collection bottle 14.
[0040] In the present invention, a collection bottle 14 is provided between the connecting pipe 7 and the suction pipe 5. The connecting pipe 7 is movably connected to the collection bottle 14. Therefore, after use, the connecting pipe 7 can be removed from the collection bottle 14, thereby achieving the purpose of convenient disassembly and cleaning. The bottom of the collection bottle 14 is provided with a sealing cover 15 for sealing the storage space of body fluid or foreign matter to prevent liquid leakage. One end of the suction pipe 5 extends to the inner bottom of the collection bottle 14 to ensure that foreign matter and body fluid can completely enter the collection bottle 14 and deposit at the bottom, avoiding blocking the suction pipe 5. One end of the connecting pipe 7 is located at the inner top of the collection bottle 14 for transmitting air flow between the connecting pipe 7 and the suction cylinder 6, while preventing body fluid from flowing back into the connecting pipe 7. Therefore, when the device is in use, foreign matter or body fluid inhaled by the suction pipe 5 can be effectively separated and stored in the collection bottle 14, and the connecting pipe 7 always remains clean and unobstructed, effectively preventing cross-contamination during operation. After cleaning, the collected liquid and foreign matter can be quickly discharged by opening the sealing cover 15, greatly improving the cleaning convenience and use efficiency of the device.
[0041] Please refer to the attached Figure 1 , Figure 2 , Figure 3 , Figure 8 and Figure 9 , a support plate 16 is fixedly connected to the middle of one side of the outer wall of the lower arc rod 21. A connecting plate 17 is fixedly connected to the bottom of one end of the suction pipe 5. The connecting plate 17 is movably connected to the middle of the support plate 16, and a connecting rod 18 is fixedly connected to the middle of the connecting plate 17. The connecting rod 18 passes through the middle of the support plate 16, and a pressure ring 19 is threadedly connected to the outside of the connecting rod 18.
[0042] In the present invention, a pressure ring 19 is threadedly connected to the outside of the connecting rod 18. The pressure ring 19 rotates to fix and release the position of the connecting plate 17, and can quickly lock the suction pipe 5 in a specific position, avoiding dislocation of the suction pipe 5 or a decrease in the efficiency of foreign matter cleaning caused by movement during operation. At the same time, when it is necessary to adjust the position of the suction pipe 5, it is more convenient. Just loosen or tighten the pressure ring 19 to achieve flexible adjustment and stable fixation of the suction pipe 5, ensuring that the suction pipe 5 can be accurately positioned to the target area in the patient's oral cavity, enhancing the operation flexibility and adaptability of the device, and meeting the requirements of complex nursing scenarios.
[0043] Please refer to the attached Figure 1 , Figure 8 and Figure 9 , a slider 22 is fixedly connected to the outer wall of the support block 2. The slider 22 is slidably connected to the inside of the support 1. A threaded rod 23 is rotatably connected to the inside of the support 1. The bottom of the threaded rod 23 is fixedly connected to a knob 24. The threaded rod 23 is threadedly connected to the middle of the slider 22, and a fixed ring 25 is fixedly connected to the bottom of the outer wall of the threaded rod 23. The fixed ring 25 is rotatably connected to the inner bottom of the support 1.
[0044] In the present invention, the slider 22 can be slidably connected to the inside of the bracket 1, providing support and guiding functions for the horizontal movement of the support block 2, enabling the support block 2 to adjust its position relative to the bracket 1, thereby achieving precise adjustment of the overall width of the device to adapt to the oral structures and size requirements of different patients. A threaded rod 23 is rotatably connected to the inside of the bracket 1, and the threaded rod 23 is threadedly connected to the middle of the slider 22 through its threaded structure. When the threaded rod 23 is rotated, the slider 22 can be driven to translate along the slideway inside the bracket 1, thereby driving the support block 2 to make synchronous adjustments. A knob 24 is fixedly connected to the bottom of the threaded rod 23. The operator can easily control the rotation direction and amplitude of the threaded rod 23 by rotating the knob 24, thereby achieving precise adjustment of the positions of the slider 22 and the support block 2. In addition, a fixed ring 25 is fixedly connected to the bottom of the outer wall of the threaded rod 23, and the fixed ring 25 is rotatably connected to the inner bottom of the bracket 1, providing a stable fulcrum for the rotation of the threaded rod 23 to ensure that the rotation action of the threaded rod 23 is stable and without deviation.
[0045] Please refer to the attached Figure 1 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , a support cylinder 26 is fixedly connected to the middle of one side of the outer wall of the bracket 1. A pull rod 27 is movably connected to the middle of the support cylinder 26. One end of the pull rod 27 is provided with a support ring 28, and the support ring 28 is provided with an arc-shaped groove for fitting the corners of the user's mouth. An installation frame 30 is arranged on the top surface of the support cylinder 26. A plug rod 31 is slidably connected to the middle of the installation frame 30. A spring 32 is sleeved on the middle of the outer wall of the plug rod 31. A top ring 33 is fixedly connected to the middle and lower part of the outer wall of the plug rod 31. The bottom of the plug rod 31 is fixedly connected to a plug block 34, and the plug block 34 passes through the support cylinder 26 and is located inside the pull rod 27. A second dial 35 is fixedly connected to the top of the plug rod 31, and a first dial 29 is fixedly connected to one side of the pull rod 27. A slot 36 is formed at the top of the pull rod 27. The plug block 34 is wedge-shaped. The plug block 34 is located in the slot 36, and both the slot 36 and the plug block 34 are provided with inclined surfaces and vertical surfaces, and the inclined surfaces are close to the support ring 28 and the vertical surfaces are away from the support ring 28.
[0046] In the present invention, the support tube 26 can be used as a supporting structure for the pull rod 27 and the support ring 28 to provide a basis for movement and fixation, and the arc-shaped groove is designed to fit the corners of the user's mouth, and is used to fit and fix the two sides of the patient's mouth to avoid injury to the corners of the mouth due to pulling during the opening of the mouth, while further increasing the open space of the oral cavity, providing sufficient operating field and operating space for foreign body cleaning, and the insertion rod 31 adjusts the distance between the support ring 28 and the support tube 26 by sliding to adapt to the oral cavity size of different patients, and a spring 32 is sleeved on the middle part of the outer wall of the insertion rod 31. The elastic effect of the spring 32 enables the insertion rod 31 to slide flexibly while having a certain stability and resilience to avoid loose position or accidental displacement, and a top ring 33 is fixedly connected to the middle and lower part of the outer wall of the insertion rod 31. The top ring 33 serves as a limiting structure of the insertion rod 31 in the support tube 26 to ensure that the sliding range of the insertion rod 31 is controlled and will not separate from the mounting frame 30. At the same time, the plug block 34 passes through the support tube 26 and is inserted into the slot 36 of the pull rod 27. Both the plug block 34 and the slot 36 are wedge-shaped structures with inclined surfaces and vertical surfaces. The inclined surface is close to the support ring 28. When the pull rod 27 pulls the support ring 28 close to the support tube 26, the inclined surface provides a sliding guide, so that the plug block 34 is squeezed out of the slot 36 and compresses the spring 32. When the support ring 28 is fixed at the corner of the mouth, the vertical surface ensures that the plug block 34 is firmly combined in the slot 36 to prevent the pull rod 27 from sliding and causing the support ring 28 to be unstable. In addition, a second paddle 35 is fixed on the top of the plug rod 31, and a paddle 1 29 is fixed on one side of the pull rod 27. The two paddles are linked by operation to achieve rapid adjustment or unlocking of the plug rod 31 and the pull rod 27. The paddle 1 29 is used to adjust the position of the pull rod 27 to make the support ring 28 close to or away from the corner of the mouth, and the paddle 2 35 is used to control the plug block 34 to disengage from the slot 36, thereby unlocking the pull rod 27.
[0047] Working principle: When in use, first close valve 13, rotate knob 24 to drive threaded rod 23 to rotate, use threaded rod 23 to drive slider 22 to slide in bracket 1, make support block 2 contact with snap ring 4 on bracket 1, and loosen compression ring 19, so that the device can be in a standby state. When it is necessary to clean foreign objects in the oral cavity of critically ill patients, first manually open the patient's mouth and separate the upper and lower rows of teeth of the patient, then place the device in the patient's mouth. First, make suction cylinder 6 cover the patient's tongue, then move snap ring 4 between the upper and lower rows of teeth of the patient, and then rotate knob 24 to drive threaded rod 23 to rotate. Use threaded rod 23 to drive slider 22 to interact in bracket 1, and make support block 2 and snap ring 4 on bracket 1 move away from each other. At this time, the patient's mouth can be opened to increase the open space of the patient's mouth. Then pull tab 1 29 to drive pull rod 27 to slide in support cylinder 26, so that support ring 28 approaches support cylinder 26 and moves away from the middle of the patient's oral cavity. At this time, the patient's mouth corner will enter the arc-shaped groove on support ring 28. As pull rod 27 is continuously pulled, the open space of the patient's mouth can be further increased at this time. And due to the extrusion of spring 32 on top ring 33, plug 34 can be firmly inserted into slot 36 on pull rod 27. And because both plug 34 and slot 36 have inclined surfaces and vertical surfaces, when pulling support ring 28 close to support cylinder 26, plug 34 can be extruded out of slot 36 through the inclined surfaces of the two, and spring 32 is compressed. When the patient's mouth corner pulls support ring 28 away from support cylinder 26, plug 34 can be prevented from moving out of slot 36 through the vertical surface, thus ensuring the stability of the relative position between support cylinder 26 and plug 34, and thus avoiding the displacement of pull rod 27 in support cylinder 26 and ensuring the stable position of support ring 28. Then press airbag 8. And when pressing, check valve 2 11 is installed in suction pipe 5, so that the air inside airbag 8 and connecting pipe 7 can be prevented from entering suction pipe 5, and it is discharged along air outlet pipe 9. After releasing airbag 8, airbag 8 will return to a full state. And when it returns, because check valve 1 10 is installed inside air outlet pipe 9, the outside air can be prevented from entering connecting pipe 7 and airbag 8. Therefore, airbag 8 will suck the air in collection bottle 14, suction pipe 5 and suction cylinder 6. After repeating this operation, negative pressure can be generated in suction cylinder 6 to suck the patient's tongue and fix its position. Then the hose for sucking foreign objects can be inserted into the patient's oral cavity to suck out the foreign objects. And by fixing the position of the tongue, the problem that the tongue collapses and blocks the throat when removing foreign objects, resulting in a small mouth space and limited operation, thus affecting the operation of removing foreign objects can be avoided. And during use, after loosening compression ring 19, suction pipe 5 can be swung to drive suction cylinder 6 and the tongue to move. After reversing compression ring 19, it will approach connecting plate 17, and then squeeze support plate 16. At this time, the position of suction cylinder 6 can be adjusted to adjust the position of the tongue in the patient's oral cavity. And when suction cylinder 6 sucks the tongue, the body fluid on the tongue will also enter the gas cylinder along suction pipe 5. One end of suction pipe 5 is located at the bottom of collection bottle 14, and connecting pipe 7 is located at the top of collection bottle 14.Therefore, after the body fluid enters the collection bottle 14, it will not enter the connecting pipe 7 but will remain in the collection bottle 14. After use, pull the second paddle 35 to drive the insertion rod 31 and the insertion block 34 away from the pull rod 27. At this time, move the pull rod 27 away from the support cylinder 26 to cancel the pulling force on the corners of the mouth, open the valve 13 to allow external gas to enter the gas cylinder and finally enter the suction pipe 5 and the support cylinder 26. At this time, the negative pressure in the suction cylinder 6 can be eliminated to cancel the adsorption on the tongue. Finally, rotate the knob 24 to drive the threaded rod 23 to rotate. At this time, the support block 2 and the snap ring 4 on the bracket 1 approach each other, and the support for the upper and lower rows of teeth can be cancelled. Finally, the device can be taken out of the user's mouth. And after cleaning, since the connecting pipe 7 and the collection bottle 14 are movably connected, the connecting pipe 7 can be removed. Finally, rotate the sealing cover 15 to discharge the body fluid in the collection bottle 14, so as to facilitate the cleaning of the inside of the airbag 8 and the inside of the collection bottle 14.,
[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
