Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of medical devices, and particularly relates to an ICU nursing sputum suction nursing tray. BACKGROUND

[0002] In the ICU, patients are usually in a critical state and cannot effectively remove secretions in the airway due to respiratory failure, coma, unconsciousness, etc. If sputum accumulates, it may block the airway, leading to poor ventilation, and even asphyxia. This requires medical personnel to be able to timely and effectively perform sputum suction to ensure the patency of the patient's airway. The use of a nursing tray can ensure efficient and safe operation, reduce the patient's pain and anxiety, and improve the operating efficiency of nursing staff, avoiding risks caused by improper operation. It is an important tool for ensuring the patency of the patient's airway, preventing respiratory complications, improving nursing efficiency, reducing cross-infection, and improving patient comfort and safety.

[0003] The existing sputum suction tray only neatly arranges the items, but in an emergency sputum suction, medical personnel need to open the sputum suction tray cover, tear open the sterile packaging bag of the disposable sputum suction tube (this step requires two-handed operation, one hand holding the packaging bag and the other hand tearing it open), take out the sputum suction tube, hold the tube with one hand, and use the other hand to pick up the connector of the negative pressure suction tube and connect it. The entire process requires at least two times of two-handed cooperation, and the complicated operation steps in the time-critical ICU rescue can lead to time waste, and frequent contact with both hands can increase the risk of contamination, especially in emergency situations, making it difficult to quickly complete aseptic operation. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide an ICU nursing sputum suction nursing tray.

[0005] The technical solution adopted to solve the above technical problems is: an ICU nursing sputum suction nursing tray, comprising a shell with a hollow structure, wherein the top of the shell is provided in an open hole state, and a door plate is hingedly connected to one side of the shell, and a shielding assembly is installed on the top of the shell to prevent bacteria and pathogens in the air from entering the interior of the shell. A partition is fixedly connected to the inner wall of the shell, and a non-damage opening package assembly is installed at the bottom of the partition for aseptic preparation and non-contact waste disposal to reduce the risk of cross-contamination.

[0006] By integrating the three functions of aseptic use, waste collection, and infection control into an automated and linked mechanical system, the safety, efficiency, and sterility level of ICU emergency sputum suction operations are significantly improved.

[0007] Further, the shielding assembly comprises a plurality of circumferentially symmetrically distributed racks, and the racks are in sliding connection with the top of the shell, and the shell limits the racks to prevent displacement during use, one side of the rack is in transmission connection with a gear, the gear is in rotation connection with the shell, and a plurality of gears are in meshing with an inner ring gear, the top of the rack is fixedly connected with a cover plate, the cover plate is in fan-shaped structure, and when a plurality of cover plates are synchronously rotated under the driving of the inner ring gear, the fan-shaped edges are spliced to form a complete circular shielding surface, effectively sealing the opening of the top of the shell to prevent external pollutants from falling in.

[0008] By the above technical scheme, the complete process of "opening the package, taking the sputum suction tube, discarding the package, and collecting the sputum" is connected in series, the closed-loop management from preparation to waste is realized, and the operation steps and personnel movement are reduced.

[0009] Further, the bottom of the inner ring gear is fixedly connected with three support rods, the other end of the support rod is fixedly connected with a second inner ring gear, the inner wall of the second inner ring gear is in transmission connection with a plurality of second gears, the other side of the plurality of second gears away from the second inner ring gear is in transmission connection with a driving gear, the top of the driving gear is in rotation connection with a support frame, the second inner ring gear is in rotation connection with the support frame, and the support frame is in U-shaped structure.

[0010] By the above technical scheme, the design of the flow guide table allows the medical staff to directly aim the sputum suction tube at the opening, and the sputum can flow into the garbage bag below, forming a closed waste treatment channel, avoiding the aerosol pollution caused by the exposure of sputum in the environment, and protecting the safety of medical staff and the environment.

[0011] Further, the flow guide table is in U-shaped structure, the inner wall of the flow guide table is inclined, and the bottom of the flow guide table is in open state, a plurality of connecting rods are fixedly connected with the bottom surface of the support frame, the other end of the connecting rod is fixedly connected with the partition plate, and the connecting rod is between the driving gear and the second inner ring gear.

[0012] By the above technical scheme, the inner ring gear drives the circumferentially distributed gears and racks to drive all fan-shaped cover plates to open and close synchronously, ensures the accurate movement track of the cover plate, forms a tight circular shielding surface when closed, provides continuous and reliable sterile protection, and effectively isolates the pollutants in the air.

[0013] Further, the non-damaging unpacking assembly comprises a pedal rod rotationally connected with the inner wall of the shell, a sliding groove is formed through one side of the bottom of the shell, one end of the pedal rod is located in the sliding groove and outside the shell, an adjusting plate is welded at the center of the side of the pedal rod away from the inner wall of the shell, one end of the adjusting plate is rotationally connected with an L-shaped plate, the other end of the L-shaped plate is rotationally connected with a connecting piece, the rotation directions of the adjusting plate and the L-shaped plate are opposite to the rotation direction of the L-shaped plate and the connecting piece, and the connecting piece is fixedly connected with a driving rod at the end away from the L-shaped plate.

[0014] Further, the non-damaging unpacking assembly comprises a pedal rod rotationally connected with the inner wall of the shell, a sliding groove is formed through one side of the bottom of the shell, one end of the pedal rod is located in the sliding groove and outside the shell, an adjusting plate is welded at the center of the side of the pedal rod away from the inner wall of the shell, one end of the adjusting plate is rotationally connected with an L-shaped plate, the other end of the L-shaped plate is rotationally connected with a connecting piece, the rotation directions of the adjusting plate and the L-shaped plate are opposite to the rotation direction of the L-shaped plate and the connecting piece, and the connecting piece is fixedly connected with a driving rod at the end away from the L-shaped plate.

[0015] Through the above technical scheme, the distance between the moving plates can be adjusted in advance when the sputum suction tube is placed, which reflects that the design not only considers the use, but also considers the humanization in the preparation stage, so that the equipment can adapt to different specifications of consumables, and the universality and clamping stability are improved.

[0016] Further, the two moving plates are located in the openings in the bottom of the flow guide table, and the flow guide table limits and guides the two moving plates, a metal strip is welded between the two moving plates in the bottom of the flow guide table, and the metal strip is made of flexible and deformable material, and when the moving plates move along the sliding direction under the limitation of the support frame, the metal strip is deformed synchronously.

[0017] Further, the inner wall of the metal strip is magnetically connected with a magnetic metal frame, the magnetic metal frame is made of flexible and deformable magnetic metal material, and is bent and fitted synchronously with the metal strip, and a garbage bag is clamped between the metal strip and the magnetic metal frame, and the garbage bag is made of one-time polyethylene material and is bent and fitted synchronously with the metal strip.

[0018] Through the above technical scheme, the flexible metal strip and the magnetic metal frame are used to magnetically adsorb and clamp the garbage bag, which can ensure that the garbage bag will not fall off when the equipment moves or the internal mechanism moves, and is easy to separate when replaced, which is very ingenious.

[0019] Furthermore, two spring rods are slidably connected through the top of the movable plate, and the spring rods at the top of the two movable plates are arranged in a mirror symmetrical manner. Two rotating rods are rotatably connected through the end of the spring rods, and the connection between the two rotating rods and the spring rods is the central axis of the spring rods. At the same time, the two rotating rods are arranged in a V-shaped structure.

[0020] Furthermore, a clamping plate is rotatably connected to the end of the rotating rod away from the spring rod, and the two clamping plates and the corresponding side rotating rod form a clamping structure. A support plate is rotatably connected to the side of the clamping plate away from the rotating rod, and the support plate is fixedly connected to the inner wall of the moving plate.

[0021] Through the above technical solution, the clamping unit consists of a spring rod, a V-shaped rotating rod, clamping plates and a support plate forming a composite lever system. Pressing the spring rod will cause the two clamping plates to rotate around the fulcrum of the support plate, thus opening. After being released, they are stably clamped under the action of spring force, providing sufficient and gentle clamping force, which can fix the packaging bag without crushing it.

[0022] The beneficial effects of this invention are as follows: (1) The present invention drives the gear to rotate synchronously while the drive rod rotates, and the drive gear drives the No. 2 gear to mesh and rotate, thereby driving the No. 2 internal gear ring to rotate. Under the action of the support rod, the No. 1 internal gear ring at the top of the shell rotates synchronously, thereby driving the No. 1 gear to rotate, and then driving the rack to move along the shell limiting direction, thereby enabling several covers to open synchronously, ensuring the precise movement trajectory of the covers, and forming a tightly sealed circular shielding surface when closed, providing continuous and reliable sterile protection and effectively isolating pollutants in the air; (2) The present invention uses a foot pedal to rotate the pedal downwards and simultaneously drive the adjustment plate to move upwards. This causes the L-shaped plate and the adjustment plate to rotate relative to each other, while the other end of the L-shaped plate and the inclined end of the connector rotate relative to each other. This pushes the connector to move away from the drive rod, causing the rotating plate to rotate synchronously. This drives the two connecting plates to rotate synchronously around the connection point with the rotating plate, which in turn pushes the two moving plates to slide along the support frame in different directions. This causes the packaging bag of the suction tube to be gradually torn open, simulating the active tearing method of "fixing and tearing" by human hands. This is more controllable and reliable than simply breaking or cutting open the tube. It can avoid irregular rupture of the packaging bag or damage to the sterile suction tube inside. Furthermore, the foot pedal provides power, allowing medical staff to keep their hands completely free when preparing the suction tube for maintaining the patient's position, keeping the airway open, or other emergency treatment operations. This significantly improves the safety and efficiency of clinical operations. (3) After the suction tube is removed, the operator releases the foot pedal. During the resetting process, the clamp will release the waste packaging bag and let it fall naturally. The inclined inner wall of the guide platform ensures that the packaging bag can slide smoothly into the garbage bag at the bottom. Throughout the process, medical staff do not need to touch the contaminated packaging bag, cutting off an important route of cross-contamination. The entire process is contactless treatment of pollutants, which significantly reduces the risk of medical staff coming into contact with pathogens. This not only has practical health benefits, but also reduces the psychological pressure on medical staff when performing high-risk operations. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figures 1-10 As shown, this embodiment of an ICU suction tray includes a hollow shell 11 with an opening at the top. A door panel 12 is hinged to one side of the shell 11. A shielding assembly 2 is installed on the top of the shell 11 to prevent airborne bacteria and pathogens from entering the shell 11. The shielding assembly 2 includes several circumferentially symmetrically distributed racks 23. This integrates three major functions—aseptic dispensing, waste collection, and infection control—into an automated, interconnected mechanical system, significantly improving the safety, efficiency, and aseptic level of emergency suctioning operations in the ICU. The racks 23 are slidably connected to the top of the shell 11, and the shell 11 limits the racks 23 to prevent displacement during use. One side of the racks 23 is driven. A first gear 22 is connected and rotatably connected to the housing 11. At the same time, a first internal gear ring 21 meshes between several first gears 22. The first internal gear ring 21 drives the circumferentially distributed first gears 22 and racks 23, which drive all the sector-shaped cover plates 24 to open and close synchronously. This ensures that the movement trajectory of the cover plates 24 is accurate and that a tightly sealed circular shielding surface is formed when closed, providing continuous and reliable sterile protection and effectively isolating pollutants in the air. Three support rods 25 are fixedly connected to the bottom of the first internal gear ring 21, and a second internal gear ring 28 is fixedly connected to the other end of the support rods 25. Several second gears 27 are driven through the inner wall of the second internal gear ring 28, and drive gears 26 are driven through the sides of the several second gears 27 away from the second internal gear ring 28.

[0027] like Figures 2-10As shown, a support frame 14 is rotatably connected to the top of the drive gear 26. The second internal gear ring 28 is rotatably connected to the support frame 14, and the support frame 14 has an overall U-shaped structure. A guide platform 17 is fixedly connected to the top of the support frame 14. The design of the guide platform 17 allows medical staff to directly align the suction tube's discharge port with its opening, allowing sputum to flow into the waste bag 15 below, forming a closed waste disposal channel. This avoids aerosol pollution caused by sputum exposure to the environment, protecting the safety of medical staff and the environment. The guide platform 17 has an overall U-shaped structure, and its inner wall is inclined. The bottom of the guide platform 17 is open, connecting the complete process of "opening the packaging - taking out the suction tube - discarding the packaging - collecting sputum" to achieve closed-loop management from preparation to waste disposal, reducing operational steps and personnel movement. Several connecting rods 16 are fixedly connected to the bottom surface of the support frame 14, and the other end of the connecting rods 16 is connected to the partition 13. The connecting rod 16 is fixed between the drive gear 26 and the second internal gear ring 28. The top of the rack 23 is fixedly connected to the cover plate 24, which is a fan-shaped structure. When the suction tube is placed in the housing 11, the cover plate 24 can be pushed to slide a distance towards the central axis of the housing 11. As the cover plate 24 moves, it drives the rack 23 to slide synchronously. Through the transmission cooperation between the rack 23 and the first gear 22, the first gear 22 drives the first internal gear ring 21 to rotate, which in turn drives the second internal gear ring 28 and the second gear 27 to be linked. This causes the drive gear 26 to rotate stably under the limit of the support frame 14, which in turn drives the drive rod 35 to rotate in the opposite direction. This causes the two moving plates 38 to face each other a distance to accommodate the width of the suction tube packaging bag and ensure its stable clamping. When several cover plates 24 rotate synchronously under the drive of the first internal gear ring 21, their fan-shaped edges are spliced ​​together to form a complete circular shielding surface, effectively sealing the top opening of the housing 11 and preventing external contaminants from falling in.

[0028] like Figures 1-13As shown, a partition 13 is fixedly connected to the inner wall of the housing 11, and a non-destructive opening component 3 is installed at the bottom of the partition 13 for aseptic preparation and contactless waste disposal, reducing the risk of cross-contamination. The non-destructive opening component 3 includes a step rod 31 rotatably connected to the inner wall of the housing 11, and a sliding groove is formed through one side of the bottom of the housing 11. One end of the step rod 31 is located inside the sliding groove and outside the housing 11. An adjusting plate 32 is welded to the center of the side of the step rod 31 away from the inner wall of the housing 11, and an L-shaped plate 33 is rotatably connected to the other end of the adjusting plate 32. The other end of the plate 33 is rotatably connected to a connector 34. The rotation directions of the adjusting plate 32 and the L-shaped plate 33 are intersected with the rotation directions of the L-shaped plate 33 and the connector 34. The end of the connector 34 away from the L-shaped plate 33 is fixedly connected to a drive rod 35. The end of the drive rod 35 away from the connector 34 is rotatably connected to the center of the partition 13. The end of the drive rod 35 is rotatably connected to the drive gear 26, so that the rotation of the drive gear 26 is driven by the drive rod 35. At the same time, the end of the drive rod 35 is rotatably connected to the support frame 14.

[0029] like Figures 2-13 As shown, a rotating plate 36 is provided at the bottom of the support frame 14, and the center of the rotating plate 36 is connected and fixed to the through end of the drive rod 35. At the same time, connecting plates 37 are rotatably connected to both ends of the rotating plate 36. A movable plate 38 is rotatably connected to the end of the connecting plate 37 away from the rotating plate 36. The two movable plates 38 are located in the opening at the bottom of the guide platform 17, and the guide platform 17 limits and guides the two movable plates 38. A metal strip 18 is welded between the two movable plates 38 at the bottom of the guide platform 17. The metal strip 18 is made of flexible and deformable material. The garbage bag 15 is clamped by the magnetic adsorption of the flexible metal strip 18 and the magnetic metal frame 19. This ensures that the garbage bag 15 will not fall off when the equipment moves or the internal mechanism moves. At the same time, it is easy to separate when replacing. It is very ingenious. The inner wall of the metal strip 18 is magnetically connected to the magnetic metal frame 19. The magnetic metal frame 19 is made of flexible and deformable magnetic metal material. It bends and fits synchronously with the deformation of the metal strip 18.

[0030] like Figures 3-13As shown, a garbage bag 15 is clamped between the metal strip 18 and the magnetic metal frame 19. The garbage bag 15 is made of disposable polyethylene and bends synchronously with the deformation of the metal strip 18. When the moving plate 38 moves along the sliding direction under the limitation of the support frame 14, it causes the metal strip 18 to deform synchronously. The moving plate 38 is slidably connected to the support frame 14, and the support frame 14 limits the moving plate 38. Two spring rods 39 are slidably connected through the top of the moving plate 38, and the spring rods 39 at the top of the two moving plates 38 are arranged in a mirror symmetrical manner. Two rotating rods 310 are rotatably connected through the end of the spring rods 39, and the connection between the two rotating rods 310 and the spring rods 39 is the central axis of the spring rods 39. At the same time, the two rotating rods 310 are arranged in a V-shape. The clamping unit consists of spring rods 39. 9. The V-shaped rotating rod 310, clamping plate 311, and support plate 312 constitute a composite lever system. Pressing the spring rod 39 will cause the two clamping plates 311 to rotate around the fulcrum of the support plate 312, thus opening. After being released, they are stably clamped under the action of spring force, providing sufficient and gentle clamping force, which can fix the packaging bag without crushing it. The end of the rotating rod 310 away from the spring rod 39 is rotatably connected to the clamping plate 311, and the two clamping plates 311 and the corresponding side rotating rod 310 form a clamping structure. The side of the clamping plate 311 away from the rotating rod 310 is rotatably connected to the support plate 312, and the support plate 312 is connected and fixed to the inner wall of the moving plate 38, so that the moving plate 38 can move in the sliding direction under the limit of the support frame 14, and the end of the connecting piece 34 away from the drive rod 35 is inclined.

[0031] The working principle of this embodiment is as follows: Before use, the packaging bag with the suction tube can be placed above the guide table 17. By pushing the spring rod 39 towards the clamping plate 311, the two rotating rods 310 rotate around the central axis of the spring rod 39, and at the same time drive the clamping plate 311 to rotate around the support plate 312 as the fulcrum, thereby separating the two clamping plates 311. Then, the spring rod 39 is released, and the clamping plate 311 returns to its original position under the elastic force of the spring rod 39, clamping and fixing the edge of the packaging bag.

[0032] Then, the door panel 12 can be opened, and a disposable garbage bag 15 can be placed between the metal strip 18 and the magnetic metal frame 19. Under the magnetic attraction of the metal strip 18 and the magnetic metal frame 19, they will fit tightly together, ensuring that the garbage bag 15 will not shift or fall off during subsequent deformation. At this time, the door panel 12 can be closed, and the entire device can be moved to the ICU ward for use.

[0033] When medical staff encounter an emergency requiring suctioning, they can step on the pedal 31 to rotate it downwards, which in turn moves the adjusting plate 32 upwards. This causes the L-shaped plate 33 to rotate relative to the adjusting plate 32, while the other end of the L-shaped plate 33 rotates relative to the inclined end of the connecting piece 34. This pushes the connecting piece 34 away from the drive rod 35, causing the drive rod 35 to rotate at its connection point with the partition 13. This causes the rotating plate 36 to rotate synchronously, causing the two connecting plates 37 to rotate synchronously around their connection point with the rotating plate 36. This, in turn, pushes the two movable plates 38 to slide in opposite directions along the support frame 14.

[0034] As the movable plate 38 slides, the packaging bag of the suction tube is gradually torn open. When the foot pedal 31 reaches its lowest position, the packaging bag of the suction tube is at its maximum size, and the suction tube is fully exposed and ready for use. At this time, medical staff can quickly and directly remove the suction tube for emergency treatment.

[0035] Then, medical staff can directly push the pedal 31 upwards, which will further move the moving plate 38, so that the spring rod 39 at the top of the moving plate 38 contacts the inner wall of the housing 11, thereby compressing the spring rod 39, causing the clamping plate 311 to rotate outwards around the support plate 312, releasing the packaging bag. The packaging bag falls naturally onto the guide platform 17 under the action of gravity, and then gradually slides into the garbage bag 15, completing the automatic recycling of waste.

[0036] Furthermore, as the drive rod 35 rotates, the drive gear 26 rotates synchronously. The drive gear 26 drives the second gear 27 to mesh and rotate, which in turn drives the second internal gear ring 28 to rotate. Under the action of the support rod 25, the first internal gear ring 21 at the top of the housing 11 rotates synchronously, thereby driving the first gear 22 to rotate, which in turn drives the rack 23 to move along the limiting direction of the housing 11, thereby allowing several covers 24 to open synchronously, making it convenient for medical staff to quickly retrieve the suction tube.

[0037] When medical staff perform sputum suction, they can place the sputum outlet of the suction tube directly inside the garbage bag 15 from the top of the casing 11, so that the secretions produced during the suction process fall directly into the garbage bag 15, avoiding splashing and environmental pollution.

[0038] After the operation is completed, the garbage bag 15 can be replaced by opening the door panel 12. At this time, the metal strip 18 separates from the magnetic metal frame 19. The garbage bag 15 containing waste is taken out and replaced with a new garbage bag 15. At the same time, the new suction tube packaging bag is placed on the clamp 311 between the two sides of the moving plate 38 for clamping and fixing, so that it can be used next time. At this time, the cover plate 24 is moved to close it again to ensure that the internal structure is clean and sealed.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
