Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable anesthetic gas filtration and purification device. Background Technology

[0002] Portable anesthetic gas filtration and purification devices are used to filter and purify anesthetic gases to protect the health of medical staff and patients and reduce environmental pollution. Disposable anesthetic waste gas adsorbers typically consist of a sealed container and adsorption materials such as activated carbon and molecular sieves. Reusable portable purification devices generally have a more complex structure, including filtration systems, adsorption systems, and purification treatment systems.

[0003] However, existing portable anesthetic gas filtration and purification devices have the following drawbacks:

[0004] (1) Traditional devices mostly use bolts, clips and other fixing methods, which require tools and are time-consuming to install. When replacing the activated carbon filter element, the whole device needs to be disassembled, which is complicated and may involve contact with exhaust gas.

[0005] (2) Fixed height brackets are difficult to match different usage scenarios, resulting in the input or output pipes being bent and blocked, affecting gas flow.

[0006] Therefore, this utility model provides a convenient anesthetic gas filtration and purification device. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical and convenient anesthetic gas filtration and purification device, which solves the problem mentioned in the background art that traditional devices mostly use bolts, buckles and other fixing methods and fixed height brackets that are difficult to match different usage scenarios.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a portable anesthetic gas filtration and purification device, comprising a filter box, the filter box having a cover at its opening, the cover having an internal cavity, the cavity having a fixing component on its inner side wall, the filter box having multiple activated carbon meshes on its inner side wall, and the filter box having supporting components on both sides.

[0011] The fixing assembly includes a rotating block rotatably connected to the inner wall of the cavity and two mounting blocks slidably connected to the inner wall of the cavity. A connecting rod is hinged to the surface of the rotating block and one side of the mounting block. A spring is connected between one side of the mounting block and the inner wall of the cavity. Multiple locking blocks are fixedly connected to the other side of the mounting block. The inner wall of the filter box has a slot that matches the locking blocks.

[0012] The support assembly includes mounting cylinders fixedly connected to both sides of the filter box. The inner wall of the mounting cylinder is slidably connected to the telescopic rod. A threaded hole is opened at the bottom of one side of the mounting cylinder. A threaded knob is threadedly connected to the inner wall of the threaded hole. One end of the threaded knob is in contact with the surface of the telescopic rod. A support plate is fixedly connected to the bottom of the telescopic rod.

[0013] Optionally, an input pipe and an output pipe are fixedly connected to the front and back of the filter box, respectively. One end of the input pipe and the output pipe extends into the interior of the filter box. The input pipe is connected to the exhaust gas outlet of the anesthesia device, and the output pipe is connected to the exhaust pipe or an external purification system, forming a unidirectional airflow path to ensure that the anesthetic exhaust gas flows in a fixed direction and avoids backflow pollution.

[0014] Optionally, the inner wall of the filter box is fixedly connected with multiple positioning strips, and the activated carbon mesh is slidably connected between two positioning strips. The two positioning strips form a sliding track to restrict the lateral movement of the activated carbon mesh, ensure that the filter mesh is perpendicular to the airflow direction, prevent gas from bypassing the edge of the filter mesh, and ensure that all exhaust gas must pass through the filter mesh for filtration.

[0015] Optionally, a rotating rod is fixedly connected to the top of the rotating block, and a turntable is installed on the top of the rotating rod. The back of the turntable is provided with anti-slip texture. The turntable increases the contact area with the hand, and the anti-slip texture on the back prevents slipping during operation, so that it can be easily rotated even when wearing sterile gloves.

[0016] Optionally, a limiting rod is fixedly connected to the inner wall of the cavity, and a circular groove adapted to the limiting rod is opened on one side of the mounting block. The limiting rod is inserted into the circular groove of the mounting block, restricting the mounting block to slide only along the axial direction of the limiting rod, avoiding the displacement of the locking block due to the force tilting of the connecting rod, and ensuring that the locking block is accurately embedded in the locking groove.

[0017] Optionally, a limiting block is fixedly connected to the other side of the telescopic rod, and a limiting groove adapted to the limiting block is opened on the inner wall of the mounting cylinder. The shape of the limiting block and the limiting groove match, restricting the telescopic rod to slide up and down only and not rotate, ensuring that the support plate always remains horizontal and avoiding the device from tilting due to rotation.

[0018] (III) Beneficial Effects

[0019] This utility model provides a convenient anesthetic gas filtration and purification device, which has the following beneficial effects:

[0020] 1. This portable anesthetic gas filtration and purification device drives the rotating block to rotate by rotating the turntable. The linkage between the connecting rod and the spring enables the automatic pop-out and insertion of the locking block. After the cover is quickly removed, the old activated carbon mesh can be directly pulled out and replaced with a new mesh, which can quickly complete the operation without the need for additional tools and saves the step of tightening screws one by one. It can save valuable time in emergency or transportation scenarios.

[0021] 2. This portable anesthetic gas filtration and purification device features a telescopic rod whose height can be adjusted inside the mounting cylinder via a threaded knob. This allows the device to adapt to various scenarios, enhancing portability and ensuring that the input and output pipes remain horizontal when connected, preventing gas from stagnating due to pipe tilting.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a convenient anesthetic gas filtration and purification device, including a filter box 1, with a cover 101 at the opening of the filter box 1. The cover 101 has an internal cavity, and a fixing component 2 is provided on the inner side wall of the cavity. The filter box 1 and the cover 101 are tightly connected by the fixing component 2 to form a closed cavity, ensuring that the anesthetic waste gas can only enter through the input pipe 4, and after being filtered by the activated carbon mesh 102, it is discharged from the output pipe 5 to prevent leakage and environmental pollution. Multiple activated carbon meshes 102 are provided on the inner side wall of the filter box 1, and support components 3 are provided on both sides of the filter box 1.

[0029] The fixing assembly 2 includes a rotating block 201 rotatably connected to the inner wall of the cavity and two mounting blocks 203 slidably connected to the inner wall of the cavity. The surface of the rotating block 201 and one side of the mounting block 203 are hinged together with a connecting rod 202. By rotating the rotating block 201, the rotational motion is converted into linear sliding of the mounting block 203 by the connecting rod 202, so that the locking block 205 can be quickly inserted into the slot. One side of the mounting block 203 and the inner wall of the cavity are connected together with a spring 204. The spring 204 provides a continuous outward pushing force to ensure that the locking block 205 is tightly engaged with the slot. Multiple locking blocks 205 are fixedly connected to the other side of the mounting block 203. The inner wall of the filter box 1 is opened with a slot that matches the locking block 205.

[0030] The support assembly 3 includes a mounting cylinder 301 fixedly connected to both sides of the filter box 1. The inner wall of the mounting cylinder 301 is slidably connected to the telescopic rod 302. The telescopic rod 302 slides inside the mounting cylinder 301 and the height is locked by a threaded knob 303 to adapt to different usage scenarios. A threaded hole is opened at the bottom of one side of the mounting cylinder 301. A threaded knob 303 is threadedly connected to the inner wall of the threaded hole. One end of the threaded knob 303 contacts the surface of the telescopic rod 302. A support plate 304 is fixedly connected to the bottom of the telescopic rod 302.

[0031] The front and back of the filter box 1 are respectively fixedly connected to the inlet pipe 4 and the outlet pipe 5. One end of the inlet pipe 4 and the outlet pipe 5 extends into the interior of the filter box 1. The inlet pipe 4 is connected to the exhaust gas outlet of the anesthesia equipment, and the outlet pipe 5 is connected to the exhaust pipe or an external purification system to form a unidirectional airflow path, ensuring that the anesthetic exhaust gas flows in a fixed direction and avoiding backflow pollution.

[0032] Multiple positioning strips 6 are fixedly connected to the inner side wall of the filter box 1. The activated carbon mesh 102 is slidably connected between two positioning strips 6. The two positioning strips 6 form a sliding track to restrict the lateral movement of the activated carbon mesh 102, ensure that the filter mesh is perpendicular to the airflow direction, prevent gas from bypassing the edge of the filter mesh, and ensure that all exhaust gas must pass through the filter mesh for filtration.

[0033] A rotating rod 7 is fixedly connected to the top of the rotating block 201. A turntable 8 is installed on the top of the rotating rod 7. Anti-slip texture is provided on the back of the turntable 8. The turntable 8 increases the contact area of ​​the hand, and the anti-slip texture on the back prevents slipping during operation. It can be easily rotated even when wearing sterile gloves.

[0034] A limiting rod 9 is fixedly connected to the inner wall of the cavity. A circular groove adapted to the limiting rod 9 is opened on one side of the mounting block 203. The limiting rod 9 is inserted into the circular groove of the mounting block 203, which restricts the mounting block 203 to slide only along the axial direction of the limiting rod 9. This prevents the locking block 205 from shifting due to the force tilting of the connecting rod 202, and ensures that the locking block 205 is accurately embedded in the slot.

[0035] The telescopic rod 302 is fixedly connected to a limiting block 10 on the other side. The inner wall of the mounting cylinder 301 is provided with a limiting groove that matches the limiting block 10. The limiting block 10 and the limiting groove are matched in shape, which restricts the telescopic rod 302 to slide up and down and not rotate, ensuring that the support plate 304 always remains horizontal and preventing the device from tilting due to rotation.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: Place the cover 101 down with the opening of the filter box 1, manually rotate the turntable 8 to rotate the rotating block 201. When the rotating block 201 rotates, the connecting rod 202 pulls the mounting blocks 203 on both sides to slide inward against the elastic force of the spring 204. When the locking block 205 is aligned with the slot on the inner wall of the filter box 1, release the turntable 8. Under the action of the spring 204, the mounting block 203 slides outward, so that the locking block 205 is embedded in the slot on the inner wall of the filter box 1, thus achieving a tight fixation between the cover 101 and the filter box 1.

[0038] The second step: Loosen the threaded knob 303 to fix the telescopic rod 302. The telescopic rod 302 can slide up and down in the mounting cylinder 301. After adjusting to a suitable height, tighten the threaded knob 303 to fix it. The support plate 304 contacts the plane to provide stable support, so that the device can maintain balance in different scenarios.
