Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a surgical care oxygen concentrator with a protective structure. Background Technology

[0002] Surgical oxygen concentrators (also commonly known as medical oxygen generators / operating room oxygen generators) are core medical devices specifically designed for operating rooms, postoperative recovery, and intensive care settings. They provide high-purity, stable, and safe medical oxygen for intraoperative anesthesia support, postoperative respiratory assistance, and emergency treatment of hypoxia. Air is compressed and purified before entering a molecular sieve, where zeolite molecular sieves selectively adsorb nitrogen, enriching oxygen (≥90%). Dual towers alternately adsorb and regenerate, continuously producing oxygen 24 hours a day. The oxygen is then dried, filtered, and pressure stabilized before being output.

[0003] In existing technology, oxygen is produced by an oxygen concentrator, humidified by a humidification bottle placed on the machine, and then delivered to the patient via an oxygen delivery tube. However, during use, the humidification bottle is not secured. When the humidification bottle is bumped, it is easy to cause leakage, resulting in insufficient oxygen supply. At the same time, it will also cause the joint between the oxygen delivery tube and the humidification bottle to wear and loosen more and more, which will affect the use of the oxygen concentrator.

[0004] Therefore, it is necessary to invent a surgical oxygen machine with a protective structure to solve the above problems. Summary of the Invention

The protective blocks are fixedly connected to the front side of the machine body. A protective door is provided on the front side of the protective blocks. The dimensions of the groove and the protective blocks are adapted to the dimensions of the fixed rod, the connecting rod and the movable rod.

[0011] Furthermore, the limiting component includes a first spring and an electromagnetic block. The first spring is connected to the inner wall of the telescopic block, and the end of the movable rod located inside the telescopic block is provided with a mounting groove.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a surgical oxygen concentrator with a protective structure, such as... Figures 1 to 4As shown, the device includes a main body 1, a placement slot, a humidification bottle 2, a connecting seal, and a protective assembly. The placement slot is located on the left side of the main body 1, where the humidification bottle 2 is placed for oxygen humidification. The connecting seal is located on the connection between the humidification bottle 2 and the main body 1, sealing the humidification bottle 2 and connecting it to the patient. It is responsible for sealing and connecting the gas path, ensuring no oxygen leakage and smooth delivery. A control panel is located on the right side of the main body 1, with a float-type flow meter on one side for adjusting the output oxygen flow rate. The connecting seal assembly includes a humidification bottle cap 7, a connecting valve, a connecting pipe 8, and an oxygen delivery pipe 9. The humidification bottle cap 7 is fixedly connected to the main body 1 to seal the humidification bottle 2. The top of the humidification bottle 2 is connected to the humidification bottle cap 7 via the connecting valve, enabling gas path connection and quick assembly / disassembly. The oxygen delivery pipe 9 is connected to the side of the humidification bottle 2 via the connecting pipe 8, for delivering the humidified high-concentration oxygen to the patient. The protective components are installed on the body 1 and the placement slot to protect the humidification bottle 2. The protective components include telescopic blocks 3, moving rods 4, movable slots 5, and screws 6. The telescopic blocks 3 are located on both sides of the humidification bottle 2 to clamp and fix the humidification bottle 2. The moving rods 4 are located on one side of the telescopic blocks 3. Movable slots 5 are opened inside both sides of the placement slot. The moving rods 4 and the movable slots 5 are movably connected to each other to adjust the distance between the two telescopic blocks 3. The screws 6 pass through one side of the body 1 and are connected to the moving rods 4 to fix the position of the moving rods 4 and the telescopic blocks 3. One end of the telescopic blocks 3 is slidably connected to the inner wall of the placement slot. The moving rods 4 have multiple equally spaced threaded grooves to adapt to humidification bottles 2 of different widths. The screws 6 are threadedly connected to the threaded grooves to clamp and fix humidification bottles 2 of different sizes. The screws 6, the moving rods 4, and the telescopic blocks 3 are symmetrically arranged on both sides of the humidification bottle 2.

[0021] The machine body 1 contains components for oxygen generation, such as a compressor and molecular sieve. Sterile water in the humidification bottle 2 humidifies the dry oxygen, preventing airway damage. The humidification bottle cap 7 is fixed to the machine body 1, sealing the top of the humidification bottle 2 and receiving oxygen from the main unit. The control panel and float-type flow meter are used to observe and adjust the oxygen output flow rate. The humidified oxygen is delivered to the patient's nostrils / mask via the connecting pipe 8 and oxygen delivery pipe 9. The telescopic blocks 3 within the protective assembly clamp the humidification bottle 2 on both sides for fixation. A moving rod 4 connects to the telescopic blocks 3, causing them to move left and right. The moving rod 4 slides within the movable groove 5 to adjust the spacing. After adjustment, the rod is screwed into the threaded groove on the moving rod 4 to lock the position.

[0022] Place the humidification bottle 2 into the placement slot. Adjust the left and right telescopic blocks 3 according to the actual size of the humidification bottle 2. Push the moving rod 4 to slide in the movable slot 5, causing the telescopic blocks 3 to move closer or further away, so that the two telescopic blocks 3 are just close to the outer wall of the humidification bottle 2. Pass the screw 6 through the side wall of the machine body 1 and screw it into the corresponding threaded groove on the moving rod 4 to lock the moving rod 4 and the telescopic blocks 3, thus achieving clamping and firmly fixing the humidification bottle 2. This prevents it from shaking, tilting, or tipping over, avoiding problems such as air leakage, water backflow, cracking, and pipe pulling. It also prevents water from flowing back into the machine or choking the patient, improving the safety of use. When the machine body 1 is started, the oxygen generation unit inside the machine body 1 works, producing high-concentration dry oxygen. The oxygen enters the water inside the humidification bottle 2 through the humidification bottle cap 7 and the connecting valve. The oxygen bubbles and humidifies in the water, becoming moist oxygen. The moist oxygen is delivered from the side of the humidification bottle 2 through the connecting pipe 8 and the oxygen delivery pipe 9. The float-type flow meter on the right side displays and adjusts the flow rate in real time to complete the oxygen supply.

[0023] like Figures 4 to 5 As shown, a fixing structure is also provided between the two telescopic blocks 3. The fixing structure includes a fixing rod 10, a movable rod 11, a connecting rod 12, a fixing plate 13, and a limiting component. The fixing rod 10 is located on the side of the two telescopic blocks 3 away from the inner wall of the placement groove. The bottom of the fixing rod 10 is connected to the fixing plate 13 through the connecting rod 12. Movable rods 11 are movably connected to both ends of the fixing rod 10. One end of the movable rod 11 extends into the interior of the telescopic block 3 and is inserted into the interior of both ends of the fixing rod 10. It can extend and retract left and right, adjusting the width together with the telescopic block 3. The end of the movable rod 11 is connected to the telescopic block 3 through the limiting component, further limiting and fixing the humidification bottle 2. The limiting component includes a first spring 16 and an electromagnetic block 17. The first spring 16 is connected to the inner wall of the telescopic block 3. An installation groove is opened at the end of the movable rod 11 located in the telescopic block 3. The installation groove and the end of the first spring 16 are magnetically connected through the electromagnetic block 17. The electromagnetic block 17 is electrically attracted and de-energized to achieve electric locking / unlocking.

[0024] The two telescopic blocks 3 are clamped together or loosened outwards according to the size of the humidification bottle 2. The movable rods 11 at both ends of the fixing rod 10 can slide within the fixing rod 10, automatically adapting to the changes in the spacing of the telescopic blocks 3. At this time, the electromagnetic block 17 is in the attracted state, and the movable rod 11 is locked together with the telescopic block 3. The humidification bottle 2 is fixed by the fixing rod 10 and the telescopic block 3. When it is necessary to remove the humidification bottle 2, first turn off the power to the electromagnetic block 17 through the control panel, so that the magnetism between the two electromagnetic blocks 17 disappears, and the movable rod 11 is no longer connected to the telescopic block 3. Pull the telescopic blocks 3 to both sides to release the humidification bottle 2. Through the action of the telescopic block 3, the movable rod 11 and the fixing rod 10, the humidification bottle 2 no longer shakes or tilts, completely avoiding displacement, air leakage and water backflow. Moreover, it is easy to disassemble and assemble, without repeatedly tightening screws, and the operation is quick.

[0025] like Figures 3 to 5As shown, a groove is provided on the front side of the machine body 1, located at the bottom of the placement slot. One end of the fixed plate 13 is rotatably connected to a movable plate 14 via a rotating rod. One end of the movable plate 14 is located at the top of the groove and is slidably connected to the groove, driving the fixed plate 13 to move as a whole, achieving storage or extension. The fixed plate 13 is located on the front side of the machine body 1. Protective blocks 15 are provided on the outer side of the groove and the bottom of the fixed plate 13. The protective blocks 15 are fixedly connected to the front side of the machine body 1. A protective door is provided on the front side of the protective blocks 15. The dimensions of the groove and the protective blocks 15 are adapted to the dimensions of the fixed rod 10, the connecting rod 12 and the movable rod 11. The groove and the protective blocks accommodate the fixed rod 10, the connecting rod 12 and the movable rod 11, providing dust protection, preventing accidental contact, preventing bumps, and ensuring a neat and aesthetically pleasing appearance. The cavity at the front of the body 1, below the placement slot, is used to house protruding components such as the fixed rod 10, connecting rod 12, and movable rod 11, preventing them from being exposed. When the electromagnetic block 17 is de-energized, the movable rod 11 is no longer connected to the telescopic block 3, retracting the movable rod 11 and moving it into the fixed rod 10. Rotating the fixed plate 13 causes the fixed rod 10, connecting rod 12, and / or movable rod 11 to rotate into the protective block 15, retracting all of them into the groove. Closing the protective door ensures that the fixed rod 10, movable rod 11, and connecting rod 12 are not exposed, do not occupy space, and are safe and dustproof. When needed, the protective door is opened, and the movable plate 14 is pulled out, sliding out of the groove. The fixed plate 13 is rotated back to its initial position, and the fixed rod 10, movable rod 11, and connecting rod 12 extend out, connecting to the telescopic block 3 via the electromagnetic block 17 and the first spring 16, thereby limiting and protecting the humidification bottle 2, improving safety, stability, and reliability.

[0026] like Figures 6 to 8 As shown, the top of the telescopic block 3 on the right side of the humidification bottle 2 is rotatably connected to the support block 19 via the rotating block 18, allowing the support block 19 to be angled to adapt to oxygen delivery tubes 9 with different orientations. The top of the support block 19 is connected to the clamping block 20 via a movable component. The inner arc surface of the clamping block 20 fits against the outer wall of the oxygen delivery tube 9 to clamp and fix the oxygen delivery tube 9. The two support blocks 19 and the clamping block 20 are symmetrically arranged on the oxygen delivery tube 9, clamping the oxygen delivery tube 9 from both sides to fix the oxygen delivery tube 9 and prevent it from shaking, pulling, or falling off. The movable component includes a sliding block 21 and a fourth spring. The top of the support block 19 has a sliding groove, in which the sliding block 21 is slidably connected. The fourth spring is fixedly connected to one side of the sliding block 21, and one end of the fourth spring is fixedly connected to the inner wall of the sliding groove.

[0027] When the clamping blocks 20 on both sides are moved outward, the sliding block 21 compresses the fourth spring, opening the clamping opening and allowing the oxygen delivery tube 9 to be placed between the two clamping blocks 20. Upon releasing the grip, the fourth spring rebounds, pushing the sliding block 21 and clamping blocks 20 inward to tighten them. The inner arc surface of the clamping block 20 is pressed tightly against the outer wall of the oxygen delivery tube 9, achieving elastic clamping and fixation. Rotating the rotating block 18 drives the support block 19, allowing the angle of the rotating block 18 to be freely adjusted, preventing the oxygen delivery tube 9 from being bent, flattened, or blocked, and preventing direct pulling on the humidification bottle 2 interface, thus avoiding air leakage, water backflow, and loosening of the humidification bottle 2. Simultaneously, the fourth spring is retractable, automatically adapting the clamping opening size to different sizes of oxygen delivery tubes 9, providing strong versatility.

[0028] like Figures 7 to 9 As shown, a slot is provided at the bottom of the support block 19, and an adjustment structure is provided on the telescopic block 3 on the right side of the humidification bottle 2. The adjustment structure includes a pull block 22, a push rod 23, a second spring 24, a push block 25, and an insertion rod 26. The pull block 22 is located on one side of the telescopic block 3 on the right side of the humidification bottle 2. The pull block 22 is connected to the telescopic block 3 on the right side of the humidification bottle 2 through the second spring 24. A push rod 23 is fixedly connected to one side of the pull block 22. The push rod 23 is located inside the telescopic block 3 on the right side of the humidification bottle 2. A push block 25 is provided at the end of the push rod 23. The insertion rod 26 is fixedly connected to the top of the push block 25. The top of the insertion rod 26 passes through the telescopic block 3 on the right side of the humidification bottle 2 and is inserted into the slot. A limiting ring is provided on the outer side of the top of the rotating block 18. The limiting ring is fixedly connected to the bottom of the telescopic block 3 on the right side of the humidification bottle 2. The end of the push rod 23 is a protrusion. The side of the push block 25 near the protrusion is an inclined surface. The protrusion is located at the bottom of the inclined surface. The bottom of the insertion rod 26 is fixedly connected to the inner wall of the telescopic block 3 on the right side of the humidification bottle 2 through a third spring. The third spring is located on the side of the push block 25 away from the protrusion.

[0029] The slot and the insertion rod 26 are size-matched. After the insertion rod 26 is inserted, it can restrict the rotation of the support block 19 and achieve angle locking. The limiting ring is fixed to the bottom of the right telescopic block 3 and fits on the outside of the top of the rotating block 18 to prevent the rotating block 18 from moving up and down or shaking. This ensures that the angle adjustment of the support block 19 is stable and does not deviate. At the same time, the limiting ring, together with the rotating block 18, further improves the stability of the angle adjustment.

[0030] In the initial state, the third spring is in a naturally extended state, pushing the push block 25 upward. The push block 25 drives the insertion rod 26 to move upward. The top of the insertion rod 26 passes through the right telescopic block 3 and inserts into the slot at the bottom of the support block 19, restricting the rotation of the support block 19 around the rotating block 18. At this time, the angle of the support block 19 is fixed, and the clamping block 20 at the top can stably clamp the oxygen delivery tube 9, and will not shift its angle due to vibration or tube pulling. In addition, the second spring 24 is in a naturally extended state, the pull block 22 is not pulled, and the protrusion at the end of the push rod 23 is attached to the bottom of the inclined surface of the push block 25, without affecting the locking state of the push block 25 and the insertion rod 26.

[0031] When the angle of support block 19 needs to be adjusted or the direction of oxygen delivery tube 9 needs to be changed, pull block 22 is manually pulled outward. Pull block 22 stretches the second spring 24, and at the same time drives push rod 23 to move outward. The protrusion at the end of push rod 23 moves with push rod 23 and no longer presses the inclined surface of push block 25, causing push block 25 to move downward, compressing the third spring, and at the same time driving insertion rod 26 to move downward. The top of insertion rod 26 exits from the slot at the bottom of support block 19, releasing the lock on support block 19. At this time, support block 19 can rotate freely around rotating block 18. Adjust to a suitable angle according to the direction of oxygen delivery tube 9 to ensure that oxygen delivery tube 9 is not bent or pulled. During the adjustment process, limiting ring always restricts the vertical displacement of rotating block 18 to prevent support block 19 from shifting when it flips, ensuring adjustment accuracy. After the support block 19 is adjusted to the target angle, the pull block 22 is released; the second spring 24 elastically rebounds, causing the pull block 22 and the push rod 23 to return to their original position inward. The protrusion at the end of the push rod 23 presses against the push block 25 along the inclined surface of the push block 25, pushing the push block 25 and the insertion rod 26 upward. The top of the insertion rod 26 passes back through the right telescopic block 3 and inserts into the slot at the bottom of the support block 19. The support block 19 is locked again, and the angle is fixed. The clamping block 20 at the top continues to stably clamp the oxygen delivery tube 9, completing the adjustment and reset. Through the cooperation of the limiting ring, the double spring, and the slot of the insertion rod 26, the support block 19, the rotating block 18, and the telescopic block 3 form a stable whole, further improving the reliability of the oxygen delivery tube 9 clamping and preventing the tube from falling off or leaking air.

[0032] Working principle of this invention: Reference Figures 1 to 9 As shown, in the initial state, the movable rod 11 is located inside the fixed rod 10, and the fixed rod 10, the fixed rod 10 and the connecting rod 12 are housed in the groove. The two electromagnetic blocks 17 are in the de-energized state. When using, first adjust according to the size of the humidification bottle 2. First, put the humidification bottle 2 into the placement groove, push the movable rod 4 to slide in the movable groove 5, adjust the distance between the two telescopic blocks 3 to fit tightly against the humidification bottle 2, screw the screw 6 into the corresponding thread groove to lock the movable rod 4 and the telescopic block 3, and firmly fix the humidification bottle 2. Then open the protective door and pull out the movable plate 14 to let it out of the groove. Slide out, the fixed plate 13 rotates to the initial position via the rotating rod, causing the fixed rod 10, movable rod 11, and connecting rod 12 to extend and rotate to the front of the humidification bottle 2. Pull out the movable rod 11 so that it moves into the telescopic block 3. The control panel energizes the two electromagnetic blocks 17 to generate magnetism. Through the magnetic attraction of the electromagnetic blocks 17, the first spring 16 is stretched, so that the movable rod 11 connects to the telescopic block 3, thereby limiting and protecting the humidification bottle 2. When the width of the telescopic block 3 is adjusted, the movable rod 11 extends and retracts synchronously within the fixed rod 10, automatically adapting to the spacing.

[0033] Connect one end of the oxygen delivery tube 9 to the connecting tube 8. Pull the pull block 22 to stretch the second spring 24, causing the push rod 23 to move away from the push block 25. The protrusion no longer presses against the inclined surface of the push block 25. Under the action of gravity and the third spring, the push block 25 moves downward, causing the push block 25 to move the insertion rod 26 into the telescopic block 3, no longer engaging with the slot at the bottom of the telescopic block 3. Then adjust the angle of the support block 19 according to the oxygen delivery tube 9. After adjustment, release the pull block 22. Under the action of the second spring 24... This causes the push rod 23 to move to the push block 25, and the protrusion to press along the inclined surface, causing the push block 25 to drive the insertion rod 26 to move upward. The third spring is stretched, causing the insertion rod 26 to move into the bottom slot of the support block 19, fixing and limiting the adjusted support block 19. Then, the clamping block 20 is moved outward, compressing the fourth spring, and the oxygen delivery tube 9 is placed between the two clamping blocks 20. After being released, the fourth spring rebounds, causing the sliding block 21 and the clamping block 20 to automatically clamp the oxygen delivery tube 9, so that the other end of the oxygen delivery tube 9 is connected to the patient.

[0034] When the machine is started, the internal oxygen generation unit produces high-concentration oxygen. The oxygen enters the water in the humidification bottle 2 through the humidification bottle cap 7 and the connecting valve for humidification. The humidified oxygen is then output through the connecting pipe 8 and the oxygen delivery pipe 9 for the patient's use. The flow rate is adjusted and displayed in real time by a float-type flow meter for real-time observation, thus completing the oxygen supply.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
