Description

Technical Field

[0001] The present invention relates to the field of medical technology equipment, and in particular to an emergency nursing device for intensive care patients capable of cleaning oral foreign matter. Background Art

[0002] Many critical care patients, often unconscious, confused, or unable to protect their airways, face the problem of an accumulation of oral secretions, blood clots, and other foreign matter. If these foreign matter are not promptly removed, they can lead to airway obstruction, suffocation, or other serious complications, endangering the patient's life. This is especially true for patients who have undergone oral surgery, maxillofacial trauma, or have been intubated for a long time, as their ability to self-clear oral foreign matter is often severely inhibited or impaired.

[0003] Traditional oral cleaning methods rely primarily on manual labor, with healthcare professionals manually removing foreign objects from patients' mouths. This manual cleaning method is not only complex and inefficient, but also introduces infection risks and cannot guarantee thorough cleaning, especially when foreign objects are located deep or in hard-to-reach areas. Furthermore, manual cleaning can cause secondary damage to the patient's oral mucosa, increasing patient discomfort.

[0004] With the continuous advancement of medical technology, several automated oral care devices have been proposed to assist in the removal of oral foreign matter. However, these existing devices generally suffer from complex designs, inconvenient operation, and uneven cleaning results. Therefore, developing a more efficient, safe, and automated device for removing foreign matter from the oral cavity of critical care patients remains an urgent challenge in the field of medical equipment. Summary of the Invention

[0005] The present invention aims to provide an emergency nursing device for critical care patients that can clean oral foreign objects. Through the functional integration of extraction and flushing and a highly optimized structural design, it effectively improves the operating space and cleaning effect in the oral cavity and has a high degree of automation.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows: An emergency nursing device for critical care patients capable of clearing oral foreign matter comprises a shell, the shell comprising an outer shell and an inner shell, the inner shell being sleeved within the outer shell via an inflation assembly, a suction and flushing mechanism being provided within the inner shell, a position adjustment assembly being connected between the suction and flushing mechanism and the inner shell; the suction and flushing mechanism comprising a straw, a suction assembly being provided slidingly inside the straw, and a flushing assembly being provided slidingly outside the straw.

[0007] Furthermore, the bottom of the straw is an inverted convex structure, the suction assembly includes an extraction tube located inside the straw, an extraction chamber is provided at the bottom of the extraction tube, the extraction chamber is slidably sleeved in the straw, and a ball check valve is provided between the extraction chamber and the bottom of the straw; Furthermore, a spring is provided in the extraction chamber, and the bottom of the spring is connected to the straw.

[0008] Furthermore, a same-direction check valve is provided in the extraction pipe, and a limiting rod is provided on the inner side wall of the extraction pipe for limiting the same-direction check valve.

[0009] Furthermore, the flushing assembly includes an outer tube, an inner ring platform is provided at one end of the outer tube, the inner ring platform is slidably sleeved outside the suction tube, and an outer ring platform is provided at the end of the suction tube opposite to the inner ring platform; a water storage cavity is provided between the outer tube and the suction tube, and a plurality of flushing holes are provided on the inner ring platform.

[0010] Furthermore, an adjusting rod is connected between the outer wall of the suction pipe and the outer wall of the outer tube; a connecting platform is provided on the top of the outer tube, and a control rod is provided between the connecting platform and the extraction tube.

[0011] Furthermore, the position adjustment assembly includes four first telescopic rods, which are symmetrically arranged on the outer wall of the outer tube, and the other ends of the four first telescopic rods are slidably connected to the inner shell.

[0012] Furthermore, the inflation component includes a second telescopic rod, a support plate is provided on one end of the outer shell, one end of the second telescopic rod is connected to the support plate, and a cylinder is provided on the other end of the second telescopic rod, and the cylinder is connected to a connecting air pipe; the connecting air pipe slides through the outer shell, and the other end of the connecting air pipe is connected to the airbag provided on the inner shell.

[0013] The present invention has the following beneficial effects: 1. The present invention boasts a highly optimized design structure, featuring a compact suction and irrigation assembly. The highly integrated design of the inflation assembly, suction tube, suction assembly, and irrigation assembly significantly increases operating space while providing cleaning functions, thereby enhancing cleaning effectiveness. The coordinated operation of the suction and irrigation assemblies within and outside the tube allows for rapid and thorough removal of foreign matter from the oral cavity. Furthermore, the device's automated design effectively reduces the operational burden on medical staff, improves work efficiency, and reduces operational errors and risks, ensuring a highly efficient and safe cleaning process.

[0014] 2. The combined design of the straw's depth adjustment function and position adjustment component allows the straw to precisely target blood clots or other foreign matter in the patient's mouth. This effectively avoids damage to the patient's oral tissue during foreign matter removal, improves cleaning accuracy, and rapidly removes foreign matter from different locations, thereby enhancing cleaning efficiency and safety.

[0015] 3. The device is equipped with anti-backflow designs such as a ball check valve and a unidirectional check valve. These not only assist in the extraction process but also effectively prevent the backflow of blood clots during the suction process. This ensures that foreign matter can only flow in one direction and will not enter the airway or cause re-contamination, improving the safety of the cleaning process and reducing the risk of airway obstruction.

[0016] 4. It has a high degree of automation, such as automatic adjustment of the suction tube depth, flushing water flow control, and automatic expansion of the inflation component. These automated designs reduce the operating pressure on medical staff, reduce operational complexity and manual errors, and ensure that the device can be put into use quickly in emergency situations, saving valuable nursing time.

[0017] 5. The coordinated operation of the flushing and suction components, through the depth adjustment of the suction tube and the precise flushing hole design, achieves efficient oral cleaning. Sterile water is evenly sprayed through the flushing hole, combined with the suction function, to more thoroughly remove residues and difficult-to-absorb foreign matter, ensuring a thorough cleaning process.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "front end", "back end", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances. Example 1

[0022] This embodiment provides an emergency nursing device for critical care patients capable of cleaning oral foreign matter, such as Figures 1 to 18 As shown, the device comprises a housing 1, which includes an outer housing 11 and an inner housing 12. An inflatable assembly 2 is connected between the outer housing 11 and the inner housing 12. A suction and flushing mechanism 3 is provided within the inner housing 12, and a position adjustment assembly 4 is connected between the suction and flushing mechanism 3 and the inner housing 12. The suction and flushing mechanism 3 includes a suction tube 31, a suction assembly 32 is slidably provided inside the suction tube 31, and a flushing assembly 33 is slidably provided outside the suction tube 31. The flushing assembly 33 can also be used to adjust the insertion depth of the suction tube 31. By providing the inflatable assembly 2 between the outer housing 11 and the inner housing 12, the airbag of the inner housing 12 can be expanded after being inserted into the patient's mouth, effectively opening the mouth and providing space for cleaning foreign objects when the patient is unconscious. The cooperation between the suction assembly 32 and the flushing assembly 33 inside and outside the suction tube 31 enables rapid cleaning of foreign objects. At the same time, by adjusting the suction tube depth, it ensures that foreign objects in different parts of the mouth can be accurately targeted, thereby improving the efficiency and accuracy of cleaning and reducing damage to the patient's mouth. The flushing component 33 can not only satisfy the flushing function, but also provide the function of adjusting the depth of the straw. This optimized structural design saves more operating space inside the oral cavity.

[0023] Specifically, an endotracheal tube fixing hole 122 is provided on the inner wall of the inner shell 12 for fixing the endotracheal tube and passing it into the patient's respiratory tract.

[0024] Furthermore, the suction assembly 32 includes an extraction tube 321 positioned within the straw 31. A suction chamber 3211 is located at the bottom of the extraction tube 321. The extraction chamber 3211 is slidably sleeved within the straw 31, and a ball check valve 322 is provided between the extraction chamber 3211 and the bottom of the straw 31. A spring 3212 is located within the extraction chamber 3211, the bottom of which is connected to the straw 31. This design, by providing a sliding structure between the extraction tube 321 and the extraction chamber 3211, allows the extraction chamber 3211 to move with the straw 31 as needed, flexibly adjusting its contact position with foreign objects in the oral cavity. When the extraction tube 321 moves outward, the space in the extraction chamber 3211 increases due to the sliding seal between the extraction chamber 3211 and the suction tube 31, generating negative pressure. This aligns the suction tube 31 with the attached blood clot (blood clot in the mouth is typically a three-phase state of liquid, colloid, and a small amount of tiny solids). Under the action of the negative pressure, the blood clot is drawn into the extraction chamber 3211. The provision of the ball check valve 322 prevents the blood clot from flowing back during the suction process, limiting its flow to one direction. When the extraction tube 321 is pressed downward, the volume of the extraction chamber 3211 decreases, and the blood clot is withdrawn. The addition of the spring 3212 improves the resetting efficiency of the extraction chamber 3211, making it easier for the blood clot to be drawn into the extraction chamber 3211.

[0025] Furthermore, a same-direction check valve 323 is provided within the extraction tube 321, and a limiting rod 324 is provided on the outside of the same-direction check valve 323. The same-direction check valve 323 is a spherical valve that operates in the same direction as the ball check valve 322. It provides airtightness during the extraction of blood clots into the extraction chamber 3211 and further enhances unidirectional flow control during the extraction process, preventing reverse backflow. The same-direction check valve 323 ensures smooth discharge of blood clots within the extraction tube 321. The limiting rod 324 prevents the valve ball of the same-direction check valve 323 from being dragged out of the extraction tube 321 by the blood clots.

[0026] Furthermore, the flushing assembly 33 includes an outer tube 331, one end of which is provided with an inner ring 3311. The inner ring 3311 is slidably mounted on the outside of the suction tube 31. The outer ring 311 is also provided on the end of the suction tube 31 opposite the inner ring 3311. A water storage chamber 332 is provided between the outer tube 331 and the suction tube 31, and the inner ring 3311 is provided with multiple flushing holes 3312. Both the inner ring 3311 and the outer ring 311 can be sealed against the mating surface. Due to the sliding connection between the inner ring 3311 and the suction tube 31, the suction tube 31 slides within the outer tube 331, and the insertion depth of the suction tube 31 can be adjusted as needed, thereby precisely adjusting the area of action of the flushing water flow and the aforementioned blood clot aspiration area. The water storage chamber 332 is a layer between the outer tube 331 and the straw 31. Sterile water is added to the water storage chamber 332, and the inner ring 3311 acts as a bottom to prevent it from flowing out. Although the inner ring 3311 has multiple flushing holes 3312, the holes are relatively small. Due to the surface tension of water, the sterile water in the water storage chamber 332 does not flow out automatically. When flushing is needed, the straw 31 slides, causing the outer ring 311 to seal the water storage chamber 332. Continued displacement squeezes the sterile water inside the water storage chamber 332, causing it to spray out from the multiple flushing holes 3312, completing the flushing operation. In fact, in some cases, adding medication to the sterile water is also easy to imagine. Combined with the position adjustment component 4, foreign matter inside the mouth can be fully rinsed, thereby improving the efficiency and thoroughness of oral cleaning.

[0027] Furthermore, an adjustment rod 333 is connected between the outer wall of the suction tube 31 and the outer wall of the outer tube 331; a connecting platform 3313 is provided at the top of the outer tube 331, and a control rod 3213 is provided between the connecting platform 3313 and the extraction tube 321. Both the adjustment rod 333 and the control rod 3213 can be actively extended and retracted; the adjustment rod 333 can be used to adjust the sliding position relationship between the outer tube 331 and the suction tube 31. To be precise and popular, it can push and pull the suction tube 31 so that the suction tube 31 slides inside the outer tube 331, thereby regulating the flushing assembly 33 to complete the flushing or suction depth adjustment functions, thereby making the entire device adaptable to a wide range of clinical scenarios; the control rod 3213 can be used to adjust the position of the extraction tube 321 inside the suction tube 31 to complete the suction operation of the suction assembly 32, avoiding the inconvenience of manual operation and improving operational accuracy.

[0028] Furthermore, the position adjustment assembly 4 includes four first telescopic rods 41, which are evenly connected to the outer wall of the outer tube 331. The other ends of the four first telescopic rods 41 are slidably connected to the inner housing 12. The four first telescopic rods 41 cooperate to adjust the position of the outer tube 331 and the entire suction and irrigation mechanism 3, ensuring precise positioning and adjustment based on the actual situation of blood clots in the patient's mouth, and achieving the optimal position for oral cleaning. Example 2

[0029] Based on the first embodiment, the second embodiment provides an inflatable assembly 2 structure, comprising a second telescopic rod 21. An outer housing 11 is provided with a support plate 111 at one end. The second telescopic rod 21 is connected to the support plate 111 at one end and to a cylinder 22 at the other end. The cylinder 22 is connected to a connecting air tube 23. The connecting air tube 23 slides through the outer housing 11 and is connected to the inner housing 12 at its other end. The connecting air tube 23 is connected to an air bag 121 provided within the inner housing 12. The expansion and contraction of the second telescopic rod 21 is used to inflate the air bag 121 via the cylinder 22, effectively expanding it within the oral cavity and opening the interior of the oral cavity, providing sufficient operating space for clearing foreign matter. The connecting air tube 23 is made of a rigid material and not only provides an inflation channel but also serves to stabilize the connection between the inner housing 12 and the outer housing 11. The inflatable assembly 2 allows the degree of oral expansion to be adjusted as needed, providing as much operating space as possible while avoiding damage to the patient's oral cavity. Working principle:

[0030] The emergency nursing device for critical care patients provided by the present invention, which can clean oral foreign matter, has the following working principles: 1. Inflatable component 2 opens the mouth The device's outer shell 11 and inner shell 12 are connected by an inflation assembly 2. This assembly controls the expansion of a balloon 121 within the inner shell 12. When a healthcare professional places the inner shell 12 in the patient's mouth and activates the inflation function, the balloon 121 rapidly inflates, opening the patient's mouth and providing ample space for cleaning. This process provides the necessary operating space for subsequent aspiration and flushing of clots, ensuring the device can continue to function even if the patient is unconscious or unable to protect themselves.

[0031] 2. Cooperation between the suction tube 31 and the suction assembly 32 A suction assembly 32 is slidably provided inside the straw 31, and a flushing assembly 33 is slidably provided outside the straw 31. The flushing assembly 33 not only has a flushing function but also can adjust the insertion depth of the straw 31. The overall design is very compact, saving operating space.

[0032] 3. Working principle of the suction assembly 32 The suction assembly 32 includes an extraction tube 321 located within the suction tube 31. An extraction chamber 3211 is located at the bottom of the extraction tube 321. The extraction tube 321 and the extraction chamber 3211 are axially slidable along the suction tube 31. A ball check valve 322 is located at the bottom of the suction tube 31. As the extraction tube 321 moves outward, the volume of the extraction chamber 3211 increases. This, aided by the airtightness of the unidirectional check valve 323 at the upper end of the extraction tube 321, generates negative pressure, causing blood clots to be drawn into the extraction chamber 3211 under the action of the negative pressure. The ball check valve 322 prevents backflow of blood clots during the suction process, ensuring that foreign matter can only flow in one direction and is promptly expelled.

[0033] 4. Spring return A spring 3212 is provided in the extraction chamber 3211, and the bottom of the spring 3212 is connected to the suction tube 31. The function of the spring is to ensure that the extraction chamber 3211 can be quickly reset after the blood clot is sucked out, thereby improving the extraction efficiency of the extraction chamber 3211 and making it easier for the blood clot to be extracted into the extraction chamber 3211.

[0034] 5. Working principle of flushing component 33 The flushing assembly 33 comprises an outer tube 331 and an inner ring 3311. The inner ring 3311 slides over the outer surface of the straw 31. The inner ring 3311 is provided with multiple flushing holes 3312. A water storage chamber 332 is formed between the outer tube 331 and the straw 31. This chamber is filled with sterile water. When flushing is required, by adjusting the depth of the straw 31, the outer ring 311 seals the chamber 332 and compresses the sterile water within, forcing it to spray out of the flushing holes 3312. This effectively flushes out residual oral matter and helps remove foreign matter that the straw 31 failed to fully extract.

[0035] 6. Adjustment function of position adjustment component 4 The position adjustment assembly 4 includes four first telescopic rods 41, evenly distributed on the outer wall of the outer tube 331 and slidably connected to the inner housing 12. The sliding and telescopic coordination of the four first telescopic rods 41 allows the position of the entire suction and irrigation mechanism 3 to be adjusted, ensuring that it can accurately locate the foreign matter in the patient's mouth and improve the cleaning effect.

[0036] 7. Implementation of automatic adjustment function In this device, an adjustment rod 333 connects the outer wall of the suction tube 31 to the outer wall of the outer tube 331. A connecting platform 3313 is located at the top of the outer tube 331, and a control rod 3213 is located between the outer tube 321 and the extraction tube 321. The adjustment rod 333 controls the sliding displacement of the suction tube 31 relative to the outer tube 331 by telescoping, thereby precisely adjusting the insertion depth of the suction tube 31 and the operating state of the irrigation assembly 33. The control rod 3213 controls the sliding displacement of the extraction tube 321 relative to the suction tube 31 by telescoping, thereby controlling the volume of the extraction chamber 3211 and, in turn, the operation of the suction assembly 32. These automated functions enable medical staff to complete oral cleaning more conveniently and quickly, while reducing the inconvenience and risks associated with manual operation.

[0037] 8. Functional principle of inflatable component 2 As the second telescopic rod 21 extends and retracts, the cylinder 22 continuously inflates the airbag 121 on the inner housing 12 (the principle and selection of the cylinder 22 are similar to those of conventional air pumps), allowing the airbag 121 to effectively expand within the patient's mouth, thereby expanding the oral cavity. The inflation level of the airbag 121 can be adjusted as needed to ensure maximum operating space without damaging the oral cavity, thereby improving cleaning efficiency. Specific application cases

[0038] Intensive care patients are often confused or unable to protect their airways independently. For example, some patients admitted to the intensive care unit after oral surgery or maxillofacial trauma may have blood clots in their mouths. If these foreign objects are not removed in time, they may cause airway obstruction and even endanger their lives. In such cases, the emergency care device for intensive care patients capable of cleaning oral foreign objects of the present invention can be used to extract and clean the blood clots in the patient's mouth. The application method and steps are as follows: 1. Place the inner shell and inflate it First, the medical professional places the inner housing 12 into the patient's mouth. The inner housing 12 and outer housing 11 are connected via the inflatable assembly 2. Upon activation, the airbag 121 surrounding the inner housing 12 expands, effectively opening the patient's mouth and providing ample space for subsequent cleaning. This ensures that even if the patient is unconscious, there is still ample space for cleaning.

[0039] 2. Fix the outer shell Next, the medical staff fixes the outer shell 11 on the patient's face (during specific use, the outer shell 11 can be optionally provided with an existing fixing device, such as a connecting strap, etc.) to ensure that the device is stable.

[0040] 3. Adjust the depth of the pipette and aspirate the blood clot When suctioning blood clots from the oral cavity is necessary, the position adjustment assembly 4 adjusts the position of the suction and irrigation mechanism 3 based on the patient's oral cavity conditions, aligning the suction tube 31 with the blood clot. (Specifically, the location of the blood clot can be determined by installing existing lighting, a miniature camera, or sensors on the inner wall of the inner housing 12, all of which are simple, conventional operations based on existing technologies.) The adjustment rod 333 of the irrigation assembly 33 then extends and contracts to adjust the insertion depth of the suction tube 31, allowing the suction tube 31 to fit or extend into the blood clot. Once the suction tube 31 is in place, the suction assembly 32 is activated, and the control rod 3213 drives the extraction tube 321, drawing the blood clot through the suction tube 31 into the extraction chamber 3211 within the device for discharge, preventing foreign matter from entering the airway.

[0041] 4. Rinse the residue and aspirate again After aspirating the clotted material, the adjustment rod 333 retracts, and the suction tube 31 retracts to the outer ring platform 311, exiting the outer tube 331. Sterile water can then be added to the water reservoir 332. The adjustment rod 333 then extends, and the suction tube 31 is repositioned. The outer ring platform 311 seals the water reservoir 332 and compresses the sterile water inside, causing it to spray out through the multiple flushing holes 3312 of the inner ring platform 3311, flushing away any remaining foreign matter. Once the flushing is complete, the suction assembly 32 is activated again to remove the water and any remaining material until the inside of the mouth is clean.

[0042] Through the above steps, the cleaning process can effectively and thoroughly remove foreign objects from the oral cavity, avoiding the inconvenience, infection risks, and patient discomfort associated with traditional cleaning methods. Furthermore, the high degree of automation reduces operational stress and labor intensity for medical staff, while improving patient safety and comfort.
