Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to a cleaning and care device for clearing foreign objects from the mouth and nasal cavity of emergency patients. Background Technology
[0002] The Department of Emergency Medicine is a comprehensive clinical department of the hospital that provides 24-hour treatment for critically ill patients. It covers general practice as well as specialized clinics such as internal medicine, surgery, obstetrics and gynecology, and pediatrics. It is mainly responsible for the emergency diagnosis and treatment of various sudden diseases such as acute trauma, cardiovascular and cerebrovascular emergencies, and poisoning. It has an integrated function of "pre-hospital emergency care - in-hospital emergency care - intensive care".
[0003] Nasal and oral cavity obstruction by foreign objects can lead to fatal consequences such as hypoxia and suffocation, requiring rapid intervention by emergency room medical staff. However, existing nasal and oral cavity foreign body removal devices require medical staff to quickly and accurately locate the foreign object and perform the extraction. During the removal process, factors such as nasal muscle contractions and tongue elevation can easily cause the removal head to shift or wobble, which can not only damage the nasal and oral mucosa but also force medical staff to repeatedly insert and remove the device and re-align it with the foreign object, thus reducing the efficiency of medical staff. Therefore, this invention provides a nasal and oral cavity foreign body removal and care device for emergency patients to solve the above problems. Summary of the Invention
[0004] This invention provides a cleaning and nursing device for clearing foreign objects from the mouth and nasal cavity of emergency patients, which solves the technical problem that the cleaning head is easily misaligned due to nasal muscle twitching or tongue elevation, requiring multiple insertions and removals for alignment, thus reducing the work efficiency of medical staff.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A device for clearing foreign objects from the mouth and nasal cavity of emergency patients includes: a bottle body with a rubber cleaning head at the top; a cleaning mechanism located on one side of the bottle body for clearing foreign objects from the patient's mouth and nasal cavity; and an adjustment mechanism located at the top of the bottle body for adjusting the angle of the rubber cleaning head. The adjustment mechanism includes two fixed seats fixedly connected to the top of the bottle body, a connecting shaft rotatably engaged with the fixed seats and connected to the rubber cleaning head, and auxiliary components cooperating with the fixed seats and the connecting shaft.
[0006] Optionally, the cleaning mechanism includes a partition fixedly connected inside the bottle body, which divides the bottle body into a suction chamber and a liquid storage chamber. The suction chamber has an air outlet pipe installed at its outlet end, and the liquid storage chamber has an air inlet pipe installed at its inlet end. A semi-circular piston plate is provided inside the liquid storage chamber. Two rectangular sliders are fixedly connected to the outer wall of the semi-circular piston plate. A limiting groove matching the rectangular sliders is provided on the inner side of the liquid storage chamber. The semi-circular piston plate is slidably connected to the liquid storage chamber through the limiting groove.
[0007] Optionally, the top of the bottle is threaded with a first sealing screw, one end of which penetrates into the interior of the liquid storage chamber, and the bottom of the bottle is threaded with two second sealing screws, one end of which penetrates into the interior of the suction chamber.
[0008] Optionally, a connecting hose is fixedly connected to the top of the bottle body. The connecting hose has two connecting channels inside. The top of the bottle body has two connecting ports, which are respectively connected to the suction chamber and the liquid storage chamber. The two connecting channels are each connected to one connecting port. The inner side of the rubber cleaning head has a suction chamber and a delivery chamber. The two connecting channels are respectively matched with the shapes of the suction chamber and the delivery chamber. The suction chamber and the delivery chamber are respectively connected to the suction chamber and the liquid storage chamber through a connecting channel. A second one-way valve is installed at the output end of the delivery chamber and the input end of the suction chamber.
[0009] Optionally, the cleaning mechanism further includes an airbag disposed on one side of the bottle body. The airbag has a first one-way valve installed at its inlet and outlet ends. The first one-way valve has a first hose installed at its vent end. One end of the first hose is rotatably connected to a threaded seat. One end of the outlet pipe and the inlet pipe are respectively fixedly connected to a threaded connector that matches the threaded seat.
[0010] Optionally, both ends of the connecting shaft extend through to both sides of the fixed base, and one end of the two connecting shafts is fixedly connected to the outer wall of the rubber cleaning head.
[0011] Optionally, the adjusting mechanism further includes a movable circular plate rotatably connected to one side of each of the two fixed seats. The movable circular plate is sleeved on the outer wall of the connecting shaft. A limit screw is threaded to one side of the connecting shaft, and one end of the limit screw extends through to the outside of the movable circular plate. A torsion spring is installed between the connecting shaft and the movable circular plate.
[0012] Optionally, the auxiliary component includes an arc-shaped piston chamber fixedly connected to one side of the movable circular plate, an arc-shaped piston rod slidably connected to the inner side of the arc-shaped piston chamber, one end of the arc-shaped piston rod extending through to the outside of the arc-shaped piston chamber and fixedly connected to a fixing plate, and one end of the fixing plate fixedly connected to the inner side of the connecting shaft.
[0013] Optionally, the auxiliary component further includes an auxiliary piston chamber fixedly connected to one side of each of the two fixed seats, an auxiliary piston rod being slidably connected inside the auxiliary piston chamber, and a second flexible hose being installed between the venting groove of the auxiliary piston chamber and the venting groove of the arc-shaped piston chamber.
[0014] Optionally, the auxiliary component further includes a fixed clamping plate fixedly connected to the inner sides of the two fixed seats. The inner sides of the two fixed seats are provided with movable clamping plates. A limiting slider is fixedly connected to each end of the movable clamping plate. A limiting groove matching the limiting slider is opened on the inner side of the fixed seat. The limiting slider is slidably connected to the fixed seat through the limiting groove. One end of the limiting slider extends to the outer side of the fixed seat, and one end of the auxiliary piston rod passes through the outside of the auxiliary piston chamber and is fixedly connected to one side of the limiting slider.
[0015] The beneficial effects of the above-described technical solution of the present invention are as follows: In the above solution, by setting up a cleaning mechanism, ordinary suction equipment only has a single negative pressure suction function. Direct suction is prone to problems such as "not being able to suck up and having a lot of residue". This device achieves the linkage operation of "spraying and softening and negative pressure suction" through airbag drive, which reduces the cleaning difficulty, significantly reduces the foreign matter residue rate, and improves the cleaning efficiency compared with ordinary equipment.
[0016] By incorporating components such as torsion springs, if the cleaning head is a rigid fixed structure, it is prone to hard collisions with the mucous membrane, causing scratches and bleeding. However, the elastic buffering effect of the torsion spring can dissipate the impact of external forces. At the same time, the rubber cleaning head itself has flexible characteristics, and with double protection, hard damage can be avoided, thereby improving the overall practicality of the equipment.
[0017] By incorporating components such as a fixed clamp, if the rubber cleaning head rotates excessively due to the patient's movements, it is very easy to poke deep into the nasal cavity or the pharyngeal mucosa, causing scratches, bleeding, or even airway irritation and choking. This structure can automatically reduce the spray and suction intensity step by step when the cleaning head deflects excessively, and stop the machine directly after exceeding the limit, avoiding risks such as mucosal damage and accidental aspiration of medication into the trachea, thereby improving the work efficiency of medical staff.

Detailed Implementation
[0029] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0030] like Figures 1 to 9As shown, an embodiment of the present invention provides a cleaning and care device for clearing foreign objects from the oral and nasal cavities of emergency patients, comprising: a bottle body 1, wherein a rubber cleaning head 11 is provided on the top of the bottle body 1; a cleaning mechanism located on one side of the bottle body 1 for cleaning foreign objects obstructing the patient's oral and nasal cavities; and an adjustment mechanism located on the top of the bottle body 1 for adjusting the angle of the rubber cleaning head 11, wherein the adjustment mechanism includes two fixed seats 8 fixedly connected to the top of the bottle body 1, a connecting shaft 9 rotatably cooperating with the fixed seats 8 and connected to the rubber cleaning head 11, and auxiliary components cooperating with the fixed seats 8 and the connecting shaft 9.
[0031] Bottle 1 serves as the base and container of the device, used to hold the cleaning solution and collect the aspirated foreign matter. A flexible rubber cleaning head 11 is mounted on its top, allowing direct contact with the patient's mouth and nasal cavity for cleaning. The rubber material effectively reduces mechanical irritation to the mucous membrane, improving operational safety and comfort. The cleaning solution is delivered to the rubber cleaning head 11 and sprayed out to soften the foreign matter, which is then sucked into bottle 1. This effectively solves the problem of traditional single negative pressure devices failing to remove dried secretions, blood clots, and other foreign matter, resulting in significant residue and greatly reducing the foreign matter residue rate, thus improving cleaning efficiency. In the adjustment mechanism, a fixed base 8 is fixed to the top of bottle 1, and a connecting shaft 9 is rotatably connected to the inside of the fixed base 8 and to the rubber cleaning head. The fixed connection 11 allows for pre-adjustment of the rubber cleaning head 11's angle by rotating the connecting shaft 9 to adapt to different patients' oral and nasal cavity structures, improving operational flexibility and accuracy. The auxiliary component absorbs impact force through elasticity when the patient suddenly twitches or the tongue touches the cleaning head, causing the cleaning head to adaptively adjust its angle, preventing hard collisions between the cleaning head and the mucosa, reducing the risk of mucosal scratches and bleeding, and improving operational safety. When the cleaning head rotates excessively due to patient movement, the auxiliary component can gradually adjust the intensity of medication spray and foreign body suction. When the cleaning head deflects to the limit angle, the cleaning function is directly terminated, effectively preventing the cleaning head from accidentally injuring sensitive structures such as the nasal mucosa and trachea, further ensuring operational safety.
[0032] Specifically, the cleaning mechanism includes a partition 12 fixedly connected inside the bottle body 1, which divides the interior of the bottle body 1 into a suction chamber 13 and a storage chamber 14. The suction chamber 13 has an exhaust pipe 2 installed at its outlet, and the storage chamber 14 has an intake pipe 3 installed at its inlet. A semi-circular piston plate 18 is installed inside the storage chamber 14, and two rectangular sliders 17 are fixedly connected to the outer wall of the semi-circular piston plate 18. A limiting groove matching the rectangular sliders 17 is provided on the inner side of the storage chamber 14. The semi-circular piston plate 18 is slidably connected to the storage chamber 14 through the limiting groove. A first sealing screw 15 is threadedly connected to the top of the bottle body 1, with one end of the first sealing screw 15 penetrating into the interior of the storage chamber 14. Two second sealing screws 16 are threadedly connected to the bottom of the bottle body 1, with one end of each second sealing screw 16 penetrating into the interior of the suction chamber 13. A connecting hose 10 is fixedly connected to the top of the bottle body 1, and two... The bottle body 1 has two connecting ports on its top, which are connected to the suction chamber 13 and the storage chamber 14 respectively. The two connecting channels are connected to one connecting port respectively. The rubber cleaning head 11 has a suction chamber 24 and a delivery chamber 32 on its inner side. The two connecting channels are matched with the shapes of the suction chamber 24 and the delivery chamber 32 respectively. The suction chamber 24 and the delivery chamber 32 are connected to the suction chamber 13 and the storage chamber 14 respectively through a connecting channel. The output end of the delivery chamber 32 and the input end of the suction chamber 24 are respectively equipped with a second one-way valve 23. The cleaning mechanism also includes an airbag 4 set on one side of the bottle body 1. The air inlet end and the air outlet end of the airbag 4 are respectively equipped with a first one-way valve 5. The air outlet end of the first one-way valve 5 is equipped with a first hose 6. One end of the first hose 6 is rotatably connected to a threaded seat 7. One end of the air outlet pipe 2 and the air inlet pipe 3 are respectively fixedly connected to a threaded connector that matches the threaded seat 7. Sealing gaskets are provided at the contact positions of the threaded seat 7 with the outlet pipe 2 and the inlet pipe 3, and at the contact positions of the first sealing screw 15 and the second sealing screw 16 with the bottle body 1. When it is necessary to remove foreign objects from a patient's mouth and nasal cavity, medical staff first connect and tighten the threaded seat 7 at the input end of the first one-way valve 5 with the threaded connector at the end of the air outlet pipe 2. Then, they connect and tighten the other threaded seat 7 with the threaded connector at the end of the air inlet pipe 3. Next, they insert the rubber cleaning head 11 into the patient's mouth and nasal cavity. At this time, they press the air bag 4, and the gas in the air bag 4 will enter the liquid storage tank 14 through one of the first hoses 6. The gas pushes the semi-circular piston plate 18 upward, causing the medicine used to clean the impurities in the mouth and nasal cavity in the liquid storage tank 14 to flow into the infusion tank 32 through one of the connecting channels of the connecting hose 10 and spray out, fully reacting with the impurities in the mouth and nasal cavity. When the medical staff releases the air bag 4... When the airbag 4 rebounds, it creates negative pressure inside the suction chamber 13. Impurities in the patient's mouth and nose, after reacting with the medication, enter from the suction chamber 24 and are then sucked into the suction chamber 13 through another connecting channel of the connecting hose 10, completing the cleaning operation of foreign objects in the mouth and nose. Ordinary suction devices only have a single negative pressure suction function. For foreign objects such as dried secretions and blood clots adhering to the mucous membranes of the mouth and nose, direct suction can easily lead to problems such as "not being able to suction and leaving a lot of residue". This device uses the airbag 4 to drive the linkage operation of "spraying and softening and negative pressure suction". First, the medication is pushed to fully react with the impurities and soften the adhering structure, and then suction is completed simultaneously. Compared with ordinary equipment, it reduces the cleaning difficulty, significantly reduces the foreign object residue rate, and improves the cleaning efficiency.
[0033] like Figures 2 to 9As shown, the adjustment mechanism, located at the top of the bottle body 1, is used to adjust the angle of the rubber cleaning head 11. The adjustment mechanism includes auxiliary components disposed above the bottle body 1. The adjustment mechanism includes two fixed seats 8 fixedly connected to the top of the bottle body 1. A connecting shaft 9 is rotatably connected to the inner side of each of the two fixed seats 8. The two ends of the connecting shaft 9 pass through to the two sides of the fixed seats 8 respectively. One end of each connecting shaft 9 is fixedly connected to the outer wall of the rubber cleaning head 11. The adjustment mechanism also includes a movable circular plate 20 rotatably connected to one side of each of the two fixed seats 8. The movable circular plate 20 is sleeved on the outer wall of the connecting shaft 9. A limit screw 27 is threadedly connected to one side of the connecting shaft 9, and one end of the limit screw 27 passes through to the outside of the movable circular plate 20. A torsion spring 19 is installed between the connecting shaft 9 and the movable circular plate 20. The auxiliary components include an arc-shaped piston chamber 28 fixedly connected to one side of the movable circular plate 20. An arc-shaped piston rod 31 is slidably connected to the inner side of the arc-shaped piston chamber 28. One end of the arc-shaped piston rod 31 extends through the outside of the arc-shaped piston chamber 28 and is fixedly connected to a fixing plate 25. One end of the fixing plate 25 is fixedly connected to the inside of the connecting shaft 9. The auxiliary component also includes an auxiliary piston chamber 30 fixedly connected to one side of the two fixing seats 8 respectively. An auxiliary piston rod 29 is slidably connected inside the auxiliary piston chamber 30. A second hose 21 is installed between the vent groove of the auxiliary piston chamber 30 and the vent groove of the arc-shaped piston chamber 28. The auxiliary component also includes a fixing clamp 22 fixedly connected to the inside of the two fixing seats 8. A movable clamp 26 is provided on the inside of the two fixing seats 8. A limiting slider is fixedly connected to each end of the movable clamp 26. A limiting groove matching the limiting slider is opened on the inside of the fixing seat 8. The limiting slider is slidably connected to the fixing seat 8 through the limiting groove. One end of the limiting slider extends to the outside of the fixing seat 8. One end of the auxiliary piston rod 29 extends through the outside of the auxiliary piston chamber 30 and is fixedly connected to one side of the limiting slider. A rubber pad is installed at the end of the limit screw 27; Before inserting the rubber cleaning head 11 into the patient's oral and nasal cavities, medical staff can first rotate the rubber cleaning head 11 to adjust the angle. During this process, the rubber cleaning head 11 will drive the two connecting shafts 9 to rotate synchronously. The connecting shafts 9 will then pull the movable circular plate 20 to rotate on one side of the fixed seat 8 through the torsion spring 19. After the angle is adjusted to the correct position, the medical staff will tighten the limiting screw 27 to make its end fit tightly against the side wall of the fixed seat 8, thereby fixing the movable circular plate 20. Then, the rubber cleaning head 11 will be inserted into the patient's oral and nasal cavities. When cleaning deep into the patient's nasal cavity, if the nasal muscles twitch, causing the rubber cleaning head 11 to shake, or if the tongue is protruding during operation in the oral cavity, the cleaning head may be affected. To prevent interference from the contact of the patient's movements, the torsion spring 19 can use its own elastic properties to drive the rubber cleaning head 11 to adaptively adjust its up and down angle, ensuring the stable operation of the cleaning work. If the cleaning head is a rigid fixed structure, when the patient suddenly moves, the cleaning head is prone to hard collision with the mucosa, causing mucosal scratches and bleeding. However, the elastic buffering effect of the torsion spring 19 can eliminate the impact of external force, making the contact of the cleaning head more gentle. At the same time, the rubber cleaning head itself has flexible properties, and the double protection can avoid hard damage. It is especially suitable for oral and nasal cavity cleaning of sensitive groups such as children, the elderly, and patients with mucosal ulcers, thereby improving the overall practicality of the equipment. When cleaning the patient's mouth and nasal cavity, or when the patient's tongue moves too much, causing the rubber cleaning head 11 to rotate too much, the connecting shaft 9 will drive the fixed plate 25 to rotate synchronously, thereby pushing the arc-shaped piston rod 31 to slide in the arc-shaped piston chamber 28. This sliding action will transport the gas in the arc-shaped piston chamber 28 to the auxiliary piston chamber 30 through the second hose 21, pushing the auxiliary piston rod 29 to move towards the fixed clamping plate 22, causing the movable clamping plate 26 and the fixed clamping plate 22 to press the connecting hose 10. The greater the range of motion of the patient's head or tongue, the greater the rotation angle of the rubber cleaning head 11, and the stronger the pressure exerted by the movable clamp 26 and the fixed clamp 22 on the connecting hose 10. Correspondingly, the pressure of the medicine spray and the negative pressure of foreign body suction of the rubber cleaning head 11 will gradually decrease. When the rotation angle of the rubber cleaning head 11 reaches its maximum limit, the connecting hose 10 will be completely pressed by the movable clamp 26 and the fixed clamp 22, and the medicine spray and foreign body suction functions will terminate simultaneously. The oral and nasal cavity cleaning operation will then stop. The oral and nasal cavity mucosa is fragile and close to important organs such as the trachea and esophagus. If the rubber cleaning head 11 is rotated excessively due to the patient's movements, it is very easy to poke the deep nasal cavity or the pharyngeal wall mucosa, causing scratches, bleeding, or even airway irritation and coughing. This structure can automatically reduce the spray and suction intensity step by step when the cleaning head is excessively deflected, and stop the machine directly after exceeding the limit, avoiding the risks of mucosal damage and accidental aspiration of medicine into the trachea, thereby improving the work efficiency of medical staff.
[0034] The working process of the cleaning and nursing device for clearing foreign objects from the mouth and nasal cavity of emergency patients provided by this invention is as follows: Sealing gaskets are provided at the contact positions of the threaded seat 7 with the outlet pipe 2 and the inlet pipe 3, and at the contact positions of the first sealing screw 15 and the second sealing screw 16 with the bottle body 1. When it is necessary to remove foreign objects from a patient's mouth and nasal cavity, medical staff first connect and tighten the threaded seat 7 at the input end of the first one-way valve 5 with the threaded connector at the end of the air outlet pipe 2. Then, they connect and tighten the other threaded seat 7 with the threaded connector at the end of the air inlet pipe 3. Next, they insert the rubber cleaning head 11 into the patient's mouth and nasal cavity. At this time, they press the air bag 4, and the gas in the air bag 4 will enter the liquid storage tank 14 through one of the first hoses 6. The gas pushes the semi-circular piston plate 18 upward, causing the medicine used to clean the impurities in the mouth and nasal cavity in the liquid storage tank 14 to flow into the infusion tank 32 through one of the connecting channels of the connecting hose 10 and spray out, fully reacting with the impurities in the mouth and nasal cavity. When the medical staff releases the air bag 4... When the airbag 4 rebounds, it creates negative pressure inside the suction chamber 13. Impurities in the patient's mouth and nose, after reacting with the medication, enter from the suction chamber 24 and are then sucked into the suction chamber 13 through another connecting channel of the connecting hose 10, completing the cleaning operation of foreign objects in the mouth and nose. Ordinary suction devices only have a single negative pressure suction function. For foreign objects such as dried secretions and blood clots adhering to the mucous membranes of the mouth and nose, direct suction can easily lead to problems such as "not being able to suction and leaving a lot of residue". This device uses the airbag 4 to achieve the linkage operation of "spraying and softening and negative pressure suction". First, the medication is pushed to fully react with the impurities and soften the adhering structure, and then suction is completed simultaneously. Compared with ordinary equipment, it reduces the cleaning difficulty, significantly reduces the foreign object residue rate, and improves the cleaning efficiency. A rubber pad is installed at the end of the limit screw 27; Before inserting the rubber cleaning head 11 into the patient's oral and nasal cavities, medical staff can first rotate the rubber cleaning head 11 to adjust the angle. During this process, the rubber cleaning head 11 will drive the two connecting shafts 9 to rotate synchronously. The connecting shafts 9 will then pull the movable circular plate 20 to rotate on one side of the fixed seat 8 through the torsion spring 19. After the angle is adjusted to the correct position, the medical staff will tighten the limiting screw 27 to make its end fit tightly against the side wall of the fixed seat 8, thereby fixing the movable circular plate 20. Then, the rubber cleaning head 11 will be inserted into the patient's oral and nasal cavities. When cleaning deep into the patient's nasal cavity, if the nasal muscles twitch, causing the rubber cleaning head 11 to shake, or if the tongue is protruding during operation in the oral cavity, the cleaning head may be affected. To prevent interference from the contact of the patient's movements, the torsion spring 19 can use its own elastic properties to drive the rubber cleaning head 11 to adaptively adjust its up and down angle, ensuring the stable operation of the cleaning work.

At the same time, the rubber cleaning head itself has flexible properties, and the double protection can avoid hard damage. It is especially suitable for oral and nasal cavity cleaning of sensitive groups such as children, the elderly, and patients with mucosal ulcers, thereby improving the overall practicality of the equipment. When cleaning the patient's mouth and nasal cavity, or when the patient's tongue moves too much, causing the rubber cleaning head 11 to rotate too much, the connecting shaft 9 will drive the fixed plate 25 to rotate synchronously, thereby pushing the arc-shaped piston rod 31 to slide in the arc-shaped piston chamber 28. This sliding action will transport the gas in the arc-shaped piston chamber 28 to the auxiliary piston chamber 30 through the second hose 21, pushing the auxiliary piston rod 29 to move towards the fixed clamping plate 22, causing the movable clamping plate 26 and the fixed clamping plate 22 to press the connecting hose 10. The greater the range of motion of the patient's head or tongue, the greater the rotation angle of the rubber cleaning head 11, and the stronger the pressure exerted by the movable clamp 26 and the fixed clamp 22 on the connecting hose 10. Correspondingly, the pressure of the medicine spray and the negative pressure of foreign body suction of the rubber cleaning head 11 will gradually decrease. When the rotation angle of the rubber cleaning head 11 reaches its maximum limit, the connecting hose 10 will be completely pressed by the movable clamp 26 and the fixed clamp 22, and the medicine spray and foreign body suction functions will terminate simultaneously.
