TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a nursing device for clearing oral and nasal cavity foreign matter of emergency patients. BACKGROUND
[0002] In the field of emergency medical treatment, clearing oral and nasal cavity foreign matter is a key operation to maintain the patency of the airway and ensure respiratory function. The commonly used oral and nasal cavity foreign matter clearing devices in the prior art mainly include negative pressure aspirators, manual curettes and simple forceps tools. The conventional negative pressure suction device usually adopts a fixed suction setting, and the foreign matter is adsorbed through a catheter connected to a negative pressure source. However, the suction force cannot be dynamically adjusted according to the contact object. If the suction force is set too high, it is easy to cause mucosal injury and bleeding when contacting the fragile mucosa of the nasal cavity and oral cavity, especially for patients with mucosal hyperemia and edema in emergency situations, the risk of such injury is higher. If the suction force is set too low, it is difficult to efficiently remove viscous secretions, food residues and other foreign matter, resulting in incomplete cleaning. At the same time, for the common adhesive foreign matter in the nasal cavity (such as blood clots and sputum scabs), simple reliance on negative pressure suction often cannot effectively remove the foreign matter due to the strong adhesion force between the foreign matter and the mucosa. In addition, the existing devices have low functional integration, and different tools are often needed for nasal and oral cleaning, which is cumbersome and difficult to adapt to the rapid response requirements in emergency situations. These problems have restricted the safety and efficiency of oral and nasal cavity foreign matter emergency cleaning.
[0003] Therefore, the technical personnel in the field propose a nursing device for clearing oral and nasal cavity foreign matter of emergency patients to solve the above problems. SUMMARY
[0004] In view of the deficiencies of the prior art, the present application provides a nursing device for clearing oral and nasal cavity foreign matter of emergency patients, which solves the problems of mucosal injury or incomplete cleaning caused by constant suction of traditional devices, and difficulty in removing adhesive foreign matter in the nasal cavity.
[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a nursing device for clearing oral and nasal cavity foreign matter of emergency patients, comprising a storage box, a nasal cavity cleaning shell and an oral cavity cleaning shell, the nasal cavity cleaning shell and the oral cavity cleaning shell are connected to the storage box through pipelines, the inside of the nasal cavity cleaning shell is provided with a self-adaptive mucosa protection assembly for automatically reducing the suction force when contacting the mucosa to protect the mucosa, and maintaining the maximum suction force when contacting the foreign matter to efficiently clean, the outside surface of the nasal cavity cleaning shell is provided with a rotary cutting assembly for cutting the nasal cavity foreign matter, and the inside of the oral cavity cleaning shell is provided with an oral cavity cleaning assembly for cleaning the oral cavity of the patient. The adaptive mucosa protection component includes a resistance block elastically connected to the front end through hole of the nasal cavity cleaning shell by a spring, the inner side of the resistance block is fixedly connected to a driving rack, two driving gears are rotatably installed on the inner front side of the nasal cavity cleaning shell, the outer eccentric part of the driving gear is rotatably connected to an adjusting rod, the inner side of the nasal cavity cleaning shell is detachably connected to an adjusting plate, and the inner side of the adjusting plate is slidably connected to two movable plates.
[0006] Through the above technical solution, by integrating the storage box, nasal cleaning shell and oral cleaning shell, integrated cleaning of foreign bodies in the oral and nasal cavities can be achieved. Among them, the adaptive mucosal protection component built into the nasal cleaning shell is the core innovative structure: with the help of the contact sensing of the resistance block, the meshing transmission of the drive rack and the drive gear one, and the mechanical linkage of the adjustment rod driving the movable plate to slide in the adjustment plate, the cross-sectional area of the adjustment plate channel is automatically reduced when contacting the mucosa to reduce the suction to protect the mucosa. When contacting foreign bodies, the channel cross-sectional area is expanded through spring reset to maintain maximum suction for efficient cleaning, which effectively solves the problem of mucosal damage or incomplete cleaning caused by constant suction of traditional devices.
[0007] Preferably, outer sides of the two driving gears are respectively engaged with outer sides of driving racks at corresponding positions, and one end of the adjusting rod is hingedly mounted on the outer side of the movable plate.
[0008] Through the above technical solution, when the resistance block is touched and moved, the driving rack converts the linear motion into the rotational motion of the driving gear one through gear meshing. The eccentric rotation of the driving gear one is transmitted to the sliding power of the moving plate through the adjusting rod, so that the moving plate can move relatively close or away from the adjusting plate, thereby dynamically changing the flow cross-sectional area of the central channel of the adjusting plate.
[0009] Preferably, the peeling assembly includes a mounting shell rotatably connected to one side of the nasal cavity cleaning shell, a micro motor 1 is installed on the outer side of the mounting shell, the output end of the micro motor 1 is fixedly connected to a driving gear 2, the outer surface of the nasal cavity cleaning shell is fixedly connected to an annular rack, a plurality of adjustment slots are opened on the outer side of the annular rack, and a cutting block is slidably installed on the inner wall of the adjustment slot.
[0010] Through the above technical solution, the motor power is converted into circumferential rotational motion of the mounting shell, which in turn drives the cutting block in the adjustment groove to slide along the groove. The adherent foreign matter in the nasal cavity is accurately peeled off through the mechanical action of the cutting block. The adjustment groove limits the sliding trajectory of the cutting block to ensure that the peeling action is controllable, effectively solving the problem that simple negative pressure suction is difficult to remove adherent foreign matter, and improving the thoroughness of nasal foreign matter cleaning.

[0012] Through the above technical solution, the reciprocating screw is driven by micro motor 2 to rotate, driving the threaded plate and the cleaning brush to realize axial reciprocating motion. At the same time, the spline sleeve is rotated by the meshing transmission of the first gear and the second gear. The intermittent cooperation between the spline shaft and the spline sleeve allows the cleaning brush to complete the rotation action synchronously, forming a composite cleaning mode of "reciprocating translation + intermittent rotation".
[0013] Preferably, the spline shaft and the spline sleeve are intermittently matched, and the second gear is rotatably mounted on the inner wall of the oral cleaning shell.
[0014] Through the above technical solution, when the threaded plate drives the spline shaft to translate to engage with the spline sleeve, the rotational power of the second gear is transmitted to the spline shaft through the spline sleeve, driving the cleaning brush to rotate to achieve brushing action; when disengaged, the cleaning brush only maintains translational cleaning. Through this intermittent transmission, it adapts to the cleaning needs of different areas of the oral cavity, enhances the comprehensiveness of cleaning and avoids the irritation of the mucosa to excessive rotation, thereby improving the safety and accuracy of oral cleaning.
[0015] Preferably, the outer surface of the oral cleaning shell is symmetrically provided with mounting grooves, the interior of the mounting groove is movably connected to a connecting rod, and the end of the connecting rod is hinged to a support ring.
[0016] Through the above technical solution, the movable connecting rod in the symmetrical installation groove on the outer surface of the oral cleaning shell and the hinged support ring at the end form an adjustable support structure: the connecting rod can be flexibly extended and retracted along the installation groove to adjust the length, and the support ring can be hinged to adapt to the oral shape and adjust the angle. When in use, the support ring fits the inner wall of the oral cavity to form a stable fulcrum, effectively dispersing the operating force to avoid shaking of the device during cleaning and reduce the risk of mucosal scratches.
[0017] Preferably, a drainage channel is opened inside the oral cleaning shell, and the drainage channel discharges foreign matter in the patient's oral cavity into the storage box through a pipe.
[0018] Through the technical scheme, the pipeline and the storage box are communicated to form a rapid discharge passage for oral cavity foreign matters; foreign matters and secretions generated by the cleaning brush can directly enter the discharge passage and be instantly transported to the storage box for centralized collection under the negative pressure of the storage box, so that the foreign matters are prevented from remaining or flowing back in the oral cavity, and the thoroughness and the operation convenience of oral cavity foreign matter cleaning are effectively improved, and the sanitary safety of the cleaning process is ensured.
[0019] Preferably, a cleaning pipe is mounted on one side of the mounting shell, one end of the cleaning pipe is communicated with a shunt pipe, and an annular pipe is mounted on the front end outside of the nasal cavity cleaning shell.
[0020] Through the technical scheme, after the cleaning pipe is connected with the washing liquid, the washing liquid is uniformly transported to the annular pipe through the shunt pipe, the annular pipe can spray annular water flow to the inner wall of the nasal cavity, and the water flow impact force can assist in loosening the adhered foreign matters, so that the nasal cavity foreign matter cleaning effect is synergistically enhanced with the negative pressure suction and the rotary cutting assembly, and the cleaning efficiency is improved.
[0021] Preferably, the cutting block is made of medical silica gel material, and the edge of the cutting block is treated by arc transition.
[0022] Through the technical scheme, the flexibility and the arc edge characteristics of the silica gel are utilized to reduce the pressure intensity of the contact with the mucosa, and sharp damage is avoided.

DETAILED DESCRIPTION
[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the present application specification. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0029] Please refer to the drawings Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a device for cleaning and nursing foreign bodies in the oral and nasal cavities of emergency patients, comprising a storage box 1, a nasal cleaning shell 2, and an oral cleaning shell 3. The nasal cleaning shell 2 and the oral cleaning shell 3 are both connected to the storage box 1 through a pipe. The interior of the nasal cleaning shell 2 is equipped with an adaptive mucosal protection component for automatically reducing suction when contacting the mucosa to protect the mucosa, and maintaining maximum suction when contacting foreign bodies for efficient cleaning. The outer surface of the nasal cleaning shell 2 is equipped with a rotary cutting component for removing foreign bodies in the nasal cavity, and the interior of the oral cleaning shell 3 is equipped with an oral cleaning component for cleaning the patient's oral cavity. The storage box 1 serves as the negative pressure source connection end and the foreign body collection terminal, and forms passages with the nasal cleaning shell 2 and the oral cleaning shell 3 through pipes, ensuring that foreign matter can be effectively collected during the cleaning process. In response to the need for cleaning foreign matter in the nasal cavity, the nasal cleaning shell 2 has a built-in adaptive mucosal protection component, which can automatically adjust the suction according to the contact object; the rotary cutting component is specially used to remove adhesive foreign matter in the nasal cavity that is difficult to remove by simple suction, thereby further enhancing the nasal cleaning effect. The oral cleaning shell 3 uses the internal oral cleaning component to solve the problem of oral foreign body cleaning in a targeted manner and achieve comprehensive cleaning of foreign matter in the oral cavity. The three work together to form a comprehensive cleaning system covering the nasal cavity and oral cavity, which is adapted to the needs of fast, safe and efficient foreign body cleaning in emergency scenarios.
[0030] The adaptive mucosal protection component includes a spring-loaded abutment block 501, which is elastically connected to the front through-hole of the nasal cavity cleaning housing 2. A drive rack 502 is fixedly connected to the inside of the abutment block 501. Two drive gears 1 503 are rotatably mounted on the front of the nasal cavity cleaning housing 2. An adjustment rod 504 is rotatably connected to the eccentric portion of the outer portion of the drive gear 1 503. An adjustment plate 505 is detachably connected to the inside of the nasal cavity cleaning housing 2. Two movable plates 506 are slidably connected to the inside of the adjustment plate 505. The outer sides of the two drive gears 1 503 are respectively meshed with the outer sides of the drive racks 502 at corresponding positions. One end of the adjustment rod 504 is hingedly mounted on the outer side of the movable plate 506.
[0031] Specifically, the abutting block 501 acts as a contact sensing component and is elastically connected to the through hole at the front end of the nasal cavity cleaning shell 2 by a spring. When the abutting block 501 contacts a rigid or sensitive part such as mucosa, it is pressed to move inward, driving the fixed drive rack 502 on the inside to move synchronously. The drive rack 502 on the outside is engaged with the two drive gears 503, converting linear motion into rotational motion of the gears. When the drive gears 503 rotate, the adjustment rod 504 connected to the eccentric part of the outside of the gears swings with the rotation of the gears, pulling the two moving plates 506 inside the adjustment plate 505 to slide along the inside track of the adjustment plate 505 to get closer, reducing the cross-sectional area of the passage in the center of the adjustment plate 505 for airflow, according to the principle of fluid mechanics, under the condition that the pressure of the negative pressure source remains unchanged, the reduction of the flow passage cross-sectional area will reduce the actual suction, thereby avoiding damage to the mucosa. When the abutting block 501 is separated from the mucosa and soft foreign matter, the spring force pushes the abutting block 501 back to its original position, the drive rack 502 and the drive gear 503 move in the opposite direction, the adjustment rod 504 drives the moving plates 506 to move away from each other, the cross-sectional area of the passage in the center of the adjustment plate 505 returns to the maximum, and the suction force rises to the high-efficiency cleaning state. Through this mechanical feedback mechanism, the cleaning needs of different contact objects can be accurately adapted.
[0032] The rotary cutting assembly includes a mounting shell 4 rotatably connected to one side of the nasal cavity cleaning shell 2. A micro motor 801 is mounted on the outside of the mounting shell 4, and the output end of the micro motor 801 is fixedly connected with a drive gear 802. The outer surface of the nasal cavity cleaning shell 2 is fixedly connected with an annular rack 803, and a plurality of adjustment grooves 804 are formed in the outer side of the annular rack 803. A cutting block 805 is slidably installed on the inner wall of the adjustment groove 804.
[0033] Specifically, when the micro motor 801 is started, the output end drives the drive gear 802 to rotate, and the drive gear 802 is engaged with the annular rack 803 fixedly connected to the outer surface of the nasal cavity cleaning shell 2. The annular rack 803 utilizes the gear transmission characteristics to make the mounting shell 4 rotate relative to the nasal cavity cleaning shell 2. The adjustment grooves 804 formed on the outer side of the annular rack 803 provide a sliding track for the cutting block 805. With the rotation of the mounting shell 4, the cutting block 805 slides synchronously along the inner wall of the adjustment groove 804. By applying a continuous shearing force to the nasal cavity adhesion foreign matter through the edge of the cutting block 805 made of medical silica gel, the separation of the foreign matter and the mucosa is achieved. The structure design of the adjustment groove 804 limits the sliding track and the extension length of the cutting block 805, and the circular arc transition treatment of the edge of the cutting block 805 ensures the peeling effect while avoiding scratching the nasal mucosa.
[0034] The oral cavity cleaning assembly comprises a micro motor two 11 installed inside the oral cavity cleaning shell 3, the driving end of the micro motor two 11 is fixedly connected with a reciprocating screw rod 16, the outer side of the reciprocating screw rod 16 is threadedly connected with a threaded plate 6, the outer side of the threaded plate 6 is rotatably installed with two threaded plates 6, the end of the threaded plate 6 is fixedly connected with a cleaning brush 10, the end of the threaded plate 6 is fixedly connected with a spline shaft 15, the outer bottom of the reciprocating screw rod 16 is fixedly connected with a first gear 13, the outer side of the first gear 13 is meshingly connected with two second gears 14, and the upper surface of the second gear 14 is fixedly connected with a spline sleeve 12. The spline shaft 15 is intermittently matched with the spline sleeve 12, and the second gear 14 is rotatably installed on the inner wall of the oral cavity cleaning shell 3.
[0035] Specifically, the micro motor two 11 serves as a power output component, the reciprocating screw rod 16 at the driving end is rotated, the reciprocating screw rod 16 drives the threaded plate 6 threadedly connected on the outer side to move reciprocatingly along the screw rod axis, so that the cleaning brush 10 at the end of the threaded plate 6 is synchronized to realize translation cleaning at different depths of the oral cavity; at the same time, the reciprocating screw rod 16 drives the first gear 13 fixedly connected at the bottom to rotate synchronously, the first gear 13 is meshingly connected with the two second gears 14 to drive the spline sleeve 12 fixedly connected on the upper surface of the second gear 14 to rotate with the gear; since the spline shaft 15 is intermittently matched with the spline sleeve 12, when the threaded plate 6 is translated to the stroke segment in which the spline shaft 15 is embedded in the spline sleeve 12, the spline sleeve 12 drives the cleaning brush 10 to rotate through spline transmission, forming a composite action of "translation + rotation", and when the threaded plate 6 is out of the matching segment, the cleaning brush 10 only keeps translation, so that the intermittent transmission mechanism is adapted to the cleaning requirement of the complex surface of the oral cavity; the auxiliary threaded plate 6 rotatably installed on the outer side of the threaded plate 6 further enhances the structural stability, ensures that the cleaning brush 10 always keeps cleaning accuracy in multidimensional movement, and effectively improves the thoroughness of foreign matter cleaning in the oral cavity.
[0036] The outer surface of the oral cavity cleaning shell 3 is symmetrically provided with a mounting groove 902, the inside of the mounting groove 902 is movably connected with a connecting rod 903, the end of the connecting rod 903 is hingedly connected with a supporting ring 901, and the inside of the oral cavity cleaning shell 3 is communicated with a drainage channel, and the drainage channel discharges foreign matter in the oral cavity of the patient into the storage box 1 through a pipeline.
[0037] Specifically, the symmetrically opened mounting grooves 902 provide a storage and limiting basis for the connecting rod 903. The connecting rod 903 can be flexibly pulled and pulled along the mounting grooves 902 to adjust its length. The support ring 901 connected at its end by a hinged structure can adjust the opening angle according to the shape of the oral cavity. When in use, the support ring 901 fits the inner wall of the oral cavity to form a stable support fulcrum, and by dispersing the operating force, the oral cleaning shell 3 is prevented from shaking and deflecting during the cleaning process, thereby reducing the risk of accidental scratches on the mucosa; at the same time, the excretion channel connected to the inside of the oral cleaning shell 3 adopts an inclined diversion design, the entrance of the channel faces the cleaning area of the cleaning brush 10, and the outlet is sealed with the storage box 1 through a pipe. When the foreign matter and secretions peeled off by the cleaning brush 10 enter the channel, they flow rapidly along the inner wall of the channel under the action of the negative pressure of the storage box 1, and the siphon effect in fluid mechanics is used to accelerate the transportation of foreign matter, and the smooth treatment of the inner wall of the channel is used to reduce residual scale.
[0038] A cleaning tube 701 is mounted on one side of the mounting housing 4, one end of which is connected to a shunt tube 702. An annular tube 703 is mounted on the outer front of the nasal cavity cleaning housing 2, one end of which is connected to the outer side of the annular tube 703. The cutting block 805 is made of medical silicone, with its edges rounded, giving the nasal cavity cleaning housing 2 a tapered design.
[0039] Specifically, the cleaning tube 701 is connected to an external flushing liquid source, and the flushing liquid is evenly distributed to the annular tube 703 through the diversion tube 702. The annular tube 703 is arranged circumferentially on the outer side of the conical front end of the nasal cleaning shell 2. The fine liquid outlet holes opened on its tube wall can spray the flushing liquid to the inner wall of the nasal cavity in the form of a low-pressure annular water flow, and the impact force of the water flow helps loosen the adhered foreign matter, forming a synergistic cleaning effect with the rotary cutting component and negative pressure suction.
[0040] Working principle: When cleaning foreign matter from the patient's nasal cavity, first slowly place the front end of the conical-shaped nasal cleaning shell 2 into the patient's nasal cavity, and establish a negative pressure passage from the nasal cleaning shell 2 to the storage box 1 through the built-in negative pressure extraction device of the storage box 1 in conjunction with the connecting pipe. In the initial state, foreign matter can be directly adsorbed and transported to the storage box 1 through negative pressure. When the nasal cleaning shell 2 is extended, if the front end of the resistance block 501 contacts the nasal mucosa, the resistance block 501 moves inward along the front end through-hole of the nasal cleaning shell 2 under the pressure of the mucosa, and the driving rack 502 fixed on its inner side translates synchronously, and then engages to drive the two driving gears 1 503 to rotate; when the driving gear 1 503 rotates, the adjustment rod 504 connected to its eccentric point swings with one end, and through the hinged relationship, pulls the two moving plates 506 in the adjustment plate 505 to slide closer relative to each other, so that the cross-sectional area of the flow hole in the center of the adjustment plate 505 is reduced, thereby reducing the negative pressure suction force and avoiding mucosal damage. When the resistance block 501 contacts a soft foreign object, the pressure exerted by the foreign object on the resistance block 501 is less than the spring force, and the spring pushes the resistance block 501 back to its original position, driving the rack 502, driving gear 1 503, and adjusting rod 504 to reset synchronously. The movable plates 506 move away from each other, and the cross-sectional area of the central hole of the adjusting plate 505 returns to its maximum, and the negative pressure suction force returns to a high-efficiency cleaning state. At the same time, the flushing liquid can be connected through the cleaning pipe 701 on the side of the mounting shell 4. The flushing liquid is introduced into the annular pipe 703 at the front end of the nasal cleaning shell 2 through the circumferential channel of the annular pipe 703 to flush the inner wall of the nasal cavity, thereby assisting in the removal of foreign objects.
[0041] For adherent foreign matter in the nasal cavity, such as blood clots, the micro motor 1 801 of the rotary cutting component is started, and its output end drives the driving gear 2 802 to rotate, and the driving gear 2 802 engages with the annular rack 803 on the outer surface of the nasal cavity cleaning shell 2, thereby driving the mounting shell 4 to rotate circumferentially relative to the nasal cavity cleaning shell 2; when the mounting shell 4 rotates, the cutting block 805 in the adjustment groove 804 outside the annular rack 803 slides synchronously with the mounting shell 4, and the cutting block 805 made of medical silicone material and with a circular arc transition on the edge is used to gently rotary cut and peel off the adherent foreign matter. After peeling, the foreign matter is immediately adsorbed to the storage box 1 by negative pressure to prevent the foreign matter from falling into the deep airway.
[0042] When cleaning foreign matter from a patient's mouth, the connecting rod 903 is first removed from the mounting groove 902 on the outer surface of the oral cleaning housing 3. The support ring 901 is then unfolded via the hinged structure, allowing the support ring 901 to fit against the inner wall of the patient's mouth, providing stable support and preventing shaking during operation. The micromotor 2 11 inside the oral cleaning housing 3 is activated, and its driving end rotates the reciprocating screw 16. The threaded plate 6, which is threadedly connected to the outer surface of the reciprocating screw 16, reciprocates along the screw's axis, and the cleaning brush 10 at the end of the threaded plate 6 moves in unison, thereby cleaning different depth areas of the oral cavity. At the same time, the reciprocating screw 16 rotates, driving the first gear 13 fixed at the bottom to rotate synchronously. The first gear 13 engages and drives the two second gears 14 to rotate, and the spline sleeve 12 on the upper surface of the second gear 14 rotates accordingly. When the threaded plate 6 translates to the position where the spline shaft 15 and the spline sleeve 12 engage, the spline sleeve 12 drives the cleaning brush 10 to rotate through the spline shaft 15, achieving a combined action of "translational cleaning + rotational brushing", improving the cleaning effect of complex oral areas such as interdental spaces and the tongue surface. Foreign matter and secretions produced by cleaning are transported through the excretion channel inside the oral cleaning shell 3 and piped to the storage box 1 for centralized collection, completing the efficient cleaning of oral foreign matter.
[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
