Description

Technical Field

[0001] This utility model relates to the field of ventilator oxygenation technology, and in particular to a ventilator oxygenation device. Background Technology

[0002] With the development of medical technology, ventilators have been widely used in the treatment of respiratory diseases, assisted breathing, and emergency care. Among the many ventilator components, the oxygenation device plays a crucial role as an important component for increasing the concentration of inhaled oxygen. In order to improve the efficiency of oxygen supply, the oxygenation device of the ventilator needs to effectively filter and purify the air during the inhalation process to ensure the purity and quality of the oxygen entering the patient's lungs. However, since there are dust, impurities, and other particulate matter in the air, these adverse substances can affect the working performance of the oxygenation device and reduce its effectiveness. Therefore, designing an oxygenation device that allows for easy cleaning and replacement of the filter components has become the key to solving this problem. Improving the filtration system and replacement method of the existing oxygenation device can greatly improve its efficiency and applicability, thereby better serving clinical treatment.

[0003] Existing ventilator oxygenation devices typically consist of multiple filters, filtration components, and airflow ducts. The oxygenation device filters out impurities, dust, and other particulate matter from the air through the filters before delivering the purified oxygen to the patient.

[0004] Existing ventilator oxygenation devices present inconveniences in the replacement and cleaning of filter components, typically requiring the disassembly of multiple parts for cleaning or replacement. Because dust and impurities easily accumulate in the filter components, their filtration efficiency significantly decreases after prolonged use, thus affecting oxygenation and reducing patient treatment outcomes. Furthermore, traditional devices fail to effectively address the ease of filter component replacement in their design, requiring medical staff to spend considerable time during operation, which can disrupt the normal operation of the equipment. Therefore, a new ventilator oxygenation device is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ventilator oxygenation device, which aims to improve the problem in the prior art where impurities and dust in the air enter the oxygenation device when it is drawing in air, resulting in poor oxygen mixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ventilator oxygenation device, comprising a support base and an oxygenator, wherein a movable wheel is fixedly connected to the bottom of the support base, a support frame is fixedly connected to the top of the support base, a controller is provided on the outer wall of the support frame, a sliding door is slidably connected inside the oxygenator, a filter screen is provided inside the sliding door, a pipe is provided on the outer wall of the support frame, and a locking component is provided on the outer wall of the oxygenator for fixing the sliding door;

[0007] The locking assembly includes a second fixed post and a locking strip. The bottom of the second fixed post is fixedly connected to the outer wall of the oxygenator. The locking strip is rotatably connected to the outer wall of the second fixed post. A pull ring is fixedly connected to the side wall of the sliding door. A first fixed post is fixedly connected to the side wall of the sliding door. The locking strip engages with the first fixed post. A hollow column is fixedly connected to the bottom of the support base. A pin assembly is provided inside the hollow column. The pin assembly is used to disassemble the oxygenator.

[0008] As a further description of the above technical solution: the pin assembly includes a sliding post and a locking block, the sliding post is slidably connected inside the hollow post, and the sidewall of the locking block is fixedly connected to one end of the sliding post;

[0009] As a further description of the above technical solution: a spring is sleeved on the outer wall of the sliding column, one end of the spring is fixedly connected to the inside of the hollow column, and the other end of the spring is fixedly connected to a retaining ring;

[0010] As a further description of the above technical solution: the top of the oxygenator is fixedly connected to a gas supply pipe, and a trapezoidal ring is slidably connected to the outer wall of the gas supply pipe;

[0011] As a further description of the above technical solution: a trapezoidal ring II is fixedly connected to the top of the gas transmission pipe, and the trapezoidal ring II is slidably connected inside the hollow column;

[0012] As a further description of the above technical solution: the gas transmission pipe is slidably connected inside the hollow column, and the trapezoidal ring is slidably connected inside the hollow column;

[0013] As a further description of the above technical solution: the trapezoidal ring II engages with the card block, and the bottom of the trapezoidal ring II is in contact with the top of the card block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the locking strip, the locking strip separates from the fixed column, and then pulling the pull ring drives the sliding door and filter screen out of the oxygenator, thereby achieving the effect of cleaning and replacing the filter components of the oxygenation device. This solves the problem that when the oxygenation device is drawing in air, impurities and dust in the air enter the oxygenation device, resulting in poor oxygen mixing effect, and improves the practicality of the ventilator oxygenation device.

[0016] 2. In this utility model, the trapezoidal ring engages with the locking block, and then the oxygenator squeezes the locking block, which in turn squeezes the spring. The spring releases its force, thus achieving the effect of installing and separating the oxygenation device and the ventilator. This solves the problem of different types of ventilators being incompatible and requiring replacement, and improves the applicability of the ventilator oxygenation device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2This utility model provides an embodiment of a ventilator oxygenation device, including a support base 1 and an oxygenator 5. The bottom of the support base 1 is fixedly connected to casters 2 for easy movement and positioning of the device. A support frame 3 is fixedly connected to the top of the support base 1. A controller 4 is installed on the outer wall of the support frame 3 to control the operation of the oxygenation device. A sliding door 8 is slidably connected inside the oxygenator 5. A filter 20 is installed inside the sliding door 8 to filter impurities from the air. A pipe 7 is installed on the outer wall of the support frame 3 to deliver oxygen to the oxygenator 5. A locking assembly is installed on the outer wall of the oxygenator 5 to fix the sliding door 8.

[0025] The locking assembly includes a second fixed column 12 and a locking strip 11. The bottom of the second fixed column 12 is fixedly connected to the outer wall of the oxygenator 5, providing stable support. The locking strip 11 is rotatably connected to the outer wall of the second fixed column 12, allowing the locking strip 11 to engage with the first fixed column 10. A pull ring 9 is fixedly connected to the side wall of the sliding door 8, facilitating the user's operation of disassembly and installation of the sliding door 8. The side wall of the sliding door 8 is also fixedly connected to the first fixed column 10, and the locking strip 11 engages with the first fixed column 10 to ensure the stability of the sliding door 8. A hollow column 6 is fixedly connected to the bottom of the support base 1. A pin assembly is set inside the hollow column 6. The pin assembly is used for quick disassembly of the oxygenation device, facilitating maintenance and replacement. The cooperation of the above components makes the installation, disassembly, and maintenance of the oxygenation device easier, while ensuring the stable operation of the equipment and the air filtration effect.

[0026] Specifically, when using a ventilator oxygenation device, the mixing process of air and oxygen requires a precise filtration component to ensure the purity of the oxygen entering the patient's lungs. During the operation of the oxygenation device, outside air is drawn in and filtered through a filter 20 installed inside the sliding door 8. The filter 20 effectively removes dust, impurities, and other particulate matter from the air, ensuring air quality. As usage time increases, the filtration efficiency of the filter 20 gradually decreases, and impurities in the air gradually accumulate on the surface of the filter 20, resulting in reduced permeability and affecting the normal operation of the oxygenation device. To maintain the filtration effect, the user can rotate the locking strip 11 to change the engagement state between the locking strip 11 and the fixing post 10, thereby separating the locking strip 11 from the fixing post 12. Then, by pulling the pull ring 9, the sliding door 8 and the filter 20 can be easily removed together for cleaning or replacement. This design effectively simplifies the maintenance process, ensuring that the oxygenation device can provide a more efficient oxygen mixing effect the next time it is used, improving the performance and ease of use of the equipment.

[0027] Reference Figure 3 and Figure 4The pin assembly includes a sliding post 14 and a locking block 19. The sliding post 14 is slidably connected inside the hollow post 6, allowing the sliding post 14 to move freely inside the hollow post 6. The locking block 19 is fixedly connected to one end of the sliding post 14 on its side wall. The locking block 19 serves to fix the oxygenation device by engaging with the trapezoidal ring 16. A spring 17 is sleeved on the outer wall of the sliding post 14. One end of the spring 17 is fixedly connected inside the hollow post 6, and the other end is connected to a fixing ring 18. The function of spring 17 is to provide a restoring force. When the pin assembly is disassembled, spring 17 can reset the sliding column 14 through the restoring force. The top of the oxygenator 5 is fixedly connected to the gas delivery pipe 13. A trapezoidal ring 15 is slidably connected to the outer wall of the gas delivery pipe 13. The trapezoidal ring 15 is slidably connected to the inside of the hollow column 6, so that the gas delivery pipe 13 can move up and down smoothly. The top of the gas delivery pipe 13 is fixedly connected to the trapezoidal ring 2 16. The trapezoidal ring 2 16 is slidably connected to the inside of the hollow column 6 to ensure the stable movement of the gas delivery pipe 13. The trapezoidal ring 2 16 engages with the locking block 19. The bottom of the trapezoidal ring 2 16 fits against the top of the locking block 19, so that the oxygenation device can be firmly fixed in the hollow column 6 in the working state and ensure the stable connection of the equipment. This structural design makes it easy to operate the pin assembly when it needs to be disassembled, and the spring 17 achieves automatic reset, making the fixing and disassembly of the oxygenation device more convenient and efficient.

[0028] Specifically, a disassembly structure is installed on top of the oxygenation device. This design improves the efficiency of connecting and disconnecting the oxygenation device from the ventilator. Through this disassembly structure, users can quickly install and disconnect the oxygenation device from the ventilator, resulting in a more convenient user experience. Specifically, firstly, by moving the oxygenation device 5, the displacement of the oxygenation device 5 causes the connected air supply tube 13 to move up and down. During this up-and-down movement, the air supply tube 13 causes trapezoidal ring 15 and trapezoidal ring 16 to move up and down together. As these two trapezoidal rings move up and down, they gradually apply pressure to the locking block 19, causing it to enter a locking state. After being compressed, the locking block 19 causes its internal spring 17 to move along with it, resulting in the compression of the spring 17. During this compression, the spring 17 gradually contracts. When the locking block 19 is no longer compressed, the elasticity of the spring 17 is released, causing the locking block 19 to spring back to its original position, thus achieving reliable engagement of the trapezoidal ring 16. The synergistic effect of this structure makes the connection and disassembly between the oxygenation device and the ventilator more efficient and stable. With the above design structure, users can easily separate and install the oxygenation device from the ventilator, while ensuring the stability and safety of the entire operation process. This innovative design not only improves the ease of use of the equipment, but also provides a more efficient solution for the maintenance and replacement of the equipment in practical application scenarios.

[0029] Working Principle: When using the oxygenation device of a ventilator, as air and oxygen are mixed, the oxygenation device draws in outside air. The air passes through the filter 20 inside the sliding door 8 to reach the oxygenator 5. The filter 20 filters out dust and impurities from the air. When the filtration effect of the filter 20 decreases to a certain extent, rotating the locking strip 11 causes it to rotate on the fixing post 12, disengaging the locking strip 11 from the fixing post 10. Then, pulling the pull ring 9 removes the sliding door 8 and the filter 20, thus achieving the maintenance and replacement of the filter 20 to improve the mixing effect of the air and oxygen next time. A disassembly structure is provided on the top of the oxygenation device, which allows for quick connection between the oxygenation device and the ventilator. The quick installation and recording process makes it more convenient. First, the oxygenator 5 is moved, which drives the air supply tube 13 to move up and down. During the up and down movement of the air supply tube 13, trapezoidal ring 15 and trapezoidal ring 16 will also move up and down. The up and down movement of trapezoidal ring 15 and trapezoidal ring 16 will squeeze and engage the locking block 19. When the locking block 19 is subjected to the squeezing force, it will drive the spring 17 and the locking block 19 to move. When the spring 17 and the locking block 19 move, the locking block 19 will squeeze the spring 17, causing the spring 17 to contract. When the locking block 19 is no longer squeezed, the spring 17 will release its elasticity, causing the locking block 19 to rebound, thereby achieving the effect of engaging the trapezoidal ring 16. Through the cooperation of the above structure, the separation and installation of the ventilator and the oxygenation device can be achieved.
