Description

Technical Field

[0001] This invention relates to the field of fish anesthesia devices, and more specifically to anesthesia devices for large aquatic organisms. Background Technology

[0002] In the fields of fish farming, fishery resource conservation, and aquatic animal medical research, it is often necessary to perform medical or research procedures on large aquatic organisms (such as Chinese sturgeon, Yangtze sturgeon, and Yangtze finless porpoise) including gonadal examination, abdominal tagging and implantation, and disease diagnosis and treatment. Because large aquatic organisms are large and have strong struggling abilities, direct handling can easily cause stress damage to the fish and even endanger the safety of the operators. Therefore, before any actual operation, the fish must be anesthetized to bring them into a stable state before proceeding with the subsequent work.

[0003] Currently, there are two main methods for anesthetizing large aquatic organisms: one is immersion anesthesia, which involves removing the fish from the aquaculture pond and transferring it to a dedicated anesthesia tank for immersion anesthesia; the other is encapsulation anesthesia, which involves using an anesthesia mask or similar device to cover the fish's head, injecting anesthetic solution into the mask, allowing the solution to enter through the fish's mouth and exit through its gills, thus achieving anesthesia. Encapsulation anesthesia is more commonly used because it does not require immersing the whole fish and uses a relatively smaller amount of anesthetic. Existing encapsulation anesthesia devices typically include a rigid or semi-rigid anesthesia mask and a connected supply line, maintaining the anesthesia state by continuously supplying anesthetic solution into the mask.

[0004] However, in practical use, it has been found that the anesthesia mask lacks an effective sealing design between itself and the fish's head. Due to the significant differences in head contours among different fish species, rigid anesthesia masks cannot fit tightly against the fish's surface. This allows anesthetic fluid to easily leak from the gaps between the mask and the fish, resulting in significant waste of anesthetic and unstable anesthetic concentrations due to fluid loss, thus affecting the anesthetic effect. Therefore, achieving a reliable seal between the anesthesia mask and the fish's head has become a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0005] This invention provides an anesthesia device for large aquatic organisms to solve the problem that existing anesthesia masks cannot reliably seal the fish's head.

[0006] The present invention provides an anesthesia device for large aquatic organisms, comprising an anesthesia mechanism and a tightening and sealing mechanism. The anesthesia mechanism includes an anesthesia cover for fitting over the head of a fish; the tightening and sealing mechanism includes a flexible seal, a tightening member, and a locking assembly. The flexible seal is disposed at the edge of the opening of the anesthesia cover to conform to the contour of the fish's head; the tightening member is disposed around the outside of the anesthesia cover to apply a tightening force to drive the flexible seal to press against the fish's head; and the locking assembly is used to hold the tightening member in a tightened state.

[0007] Beneficial effects: By incorporating a flexible seal at the edge of the anesthesia cover's opening, it adapts to the fish's head upon contact, conforming tightly to the irregular curves of the head. This allows the anesthesia cover to be used with various fish species and sizes, eliminating the need for individually designed sealing structures for each size. Furthermore, by using a tightening element surrounding the outside of the anesthesia cover and engaging a locking mechanism to maintain its tightened state, the tightening element applies a continuous and controllable radial tightening force to the anesthesia cover and its edge flexible seal during actual use. This forces the flexible seal to press firmly against the fish's head surface, effectively avoiding the unstable and insufficient sealing problems caused by relying solely on the cover's own weight or operator pressure in existing technologies. This also prevents anesthetic fluid from leaking out through the gap between the cover and the fish. In other words, the anesthetic fluid injected into the anesthesia cover can be fully utilized for absorption through the fish's gills, thus reducing waste.

[0008] In one optional embodiment, the tightening member is elastic and includes a tightening section and an adjusting section connected together; the locking assembly includes a pair of pressing plates, a driving member, and a first elastic reset member. The pair of pressing plates are symmetrically arranged on opposite sides of the adjusting section; the driving member is drively connected to at least one of the pressing plates, used to drive the pair of pressing plates towards each other or away from each other; one end of the first elastic reset member is connected to or abuts against the driving member, and the other end acts on the pressing plates; wherein, under the action of an external force, the driving member drives the pair of pressing plates away from each other, allowing the length of the adjusting section to be freely adjusted, while the first elastic reset member stores energy; when the external force is removed, the first elastic reset member releases energy, driving the pair of pressing plates towards each other and pressing against the adjusting section, locking the tightening length of the tightening member.

[0009] Beneficial Effects: By making the tightening element elastic and dividing it into a tightening section and an adjusting section, the locking assembly includes a pair of compression plates that can move closer together or further apart. When an external force causes the pair of compression plates to move apart through the driving component, the adjusting section can move freely. The operator can continuously and steplessly adjust the extension length of the adjusting section according to the actual circumference of the fish's head, thereby changing the overall tightening circumference of the tightening element to precisely match the application requirements of different fish head contours. After the external force is removed, the first elastic reset component releases energy and drives the pair of compression plates to move closer together, directly pressing the adjusting section to achieve automatic locking. This ensures that the tightening element maintains the set tightening length throughout the entire anesthesia operation cycle, thereby maintaining a constant pressure between the flexible seal and the fish's head, avoiding the risk of anesthetic leakage due to accidental loosening of the tightening element, and improving the reliability of the seal.

[0010] In one alternative embodiment, the driving component includes a handle and a movable rod. One end of the movable rod is fixed to the handle, and the other end of the movable rod is fixedly connected to the compression plate; wherein pulling the handle can move the compression plate away from the fastening component.

[0011] Beneficial effects: By fixing the movable rod to the handle, the operator only needs to pull the handle, and the movable rod will drive the pressing plate to move linearly away from the fastening component, thereby releasing the pressing plate from the fastening component (adjustment section). When it is necessary to adjust the tightening length of the fastening component, the operator can simultaneously perform the pulling action (unlocking) and tightening or loosening the fastening component with one hand. After adjustment, releasing the handle will automatically push the pressing plate back to its locking position. In other words, it achieves a pull-to-release and release-to-lock operation mode, enabling rapid unlocking.

[0012] In one alternative embodiment, an anti-slip element is fixedly provided on the side of the extrusion plate facing the adjustment section.

[0013] Beneficial effects: By fixing an anti-slip component on the side of the extrusion plate facing the adjustment section, when a pair of extrusion plates approach each other and press the adjustment section under the action of the first elastic reset component, the anti-slip component directly contacts the surface of the adjustment section. Compared with the smooth surface of the extrusion plate, the anti-slip component can significantly increase the static friction coefficient between the two, thereby effectively resisting the longitudinal tension that the adjustment section may be subjected to in the tightened state, ensuring that even under dynamic load, the adjustment section is unlikely to slip relative to each other, thus maintaining the tightening length set by the tightening component without change, and avoiding the decrease in sealing performance caused by slippage.

[0014] In one alternative embodiment, the tightening and sealing mechanism further includes an annular frame mounted on the open end of the anesthesia mask; the flexible seal is embedded inside the annular frame.

[0015] Beneficial effects: By adding an annular frame to the opening of the anesthesia mask and embedding the flexible seal inside the frame, the annular frame, acting as a rigid or semi-rigid skeleton, provides comprehensive structural support for the flexible seal. This ensures that the flexible seal maintains its intended posture when fitted onto the fish's head, preventing it from curling, folding, or shifting due to its own weight, anesthetic pressure, or friction with the fish's head. This ensures the flexible seal remains aligned with the area to be sealed on the fish's head, preventing localized leakage caused by seal displacement. Simultaneously, the annular frame, as a rigid load-bearing layer, allows for direct application of tension when a tightening element (such as an elastic band) is applied around the outside of the anesthesia mask. This tension is then evenly transmitted to the flexible seal embedded within it, preventing uneven pressure distribution caused by deformation of the anesthesia mask itself due to the absence of an annular frame.

[0016] In one optional embodiment, the anesthesia mask has an anesthetic fluid inlet and an anesthetic fluid outlet; the anesthesia mechanism further includes an anesthetic fluid storage tank, a peristaltic pump, an inlet pipe, a suction pipe, and an outlet pipe. The anesthetic fluid storage tank is used to store anesthetic fluid; the peristaltic pump is used to drive the movement of the anesthetic fluid; the inlet pipe is connected between the discharge end of the peristaltic pump and the anesthetic fluid inlet of the anesthesia mask; the suction pipe is connected between the suction end of the peristaltic pump and the anesthetic fluid storage tank; and the outlet pipe is connected between the anesthetic fluid outlet of the anesthesia mask and the anesthetic fluid storage tank.

[0017] Beneficial effects: By connecting the inlet tube to the discharge end of the peristaltic pump and the anesthetic fluid inlet of the anesthesia mask, the suction tube to the suction end of the peristaltic pump and the anesthetic fluid storage tank, and the outlet tube to the outlet of the anesthesia mask and the anesthetic fluid storage tank, and using the peristaltic pump to provide driving force, the anesthetic fluid can continuously flow along the path of the anesthetic fluid storage tank, suction tube, inlet tube, anesthesia mask, outlet tube, and anesthetic fluid storage tank. That is, the anesthetic fluid flowing out of the anesthesia mask outlet is not directly discharged, but flows back into the storage tank to participate in the circulation again. Compared with traditional immersion anesthesia or single-use and discarded drug administration methods, this allows for the reuse of anesthetic fluid, reducing the amount of anesthetic fluid required for a single anesthesia operation, thereby saving consumable costs. At the same time, because the tight sealing mechanism can effectively prevent the anesthetic fluid from leaking out from the gap between the anesthesia mask and the fish body, a low-leakage, high-recovery, energy-saving anesthesia mechanism is constructed. In addition, the anesthesia procedure can be completed on-site without the need to transport the fish or frequently replenish or change the anesthetic solution during the procedure, reducing human intervention and allowing a single person to complete the entire anesthesia process, thus lowering labor costs and simplifying the procedure.

[0018] In one alternative embodiment, the anesthesia device for large aquatic organisms further includes a support and binding mechanism, which comprises: a cover plate on the top of the anesthetic fluid storage tank; and a support column and a binding assembly. The support column is fixedly mounted on the cover plate for mounting the anesthesia mask; the binding assembly is mounted on the cover plate for binding and securing the anesthesia mask.

[0019] Beneficial effects: By installing support columns on the cover of the anesthetic fluid storage tank to support the anesthesia mask, and further adding a binding assembly to secure the anesthesia mask to the support columns, the operator can directly slip or insert the anesthesia mask onto the support columns when the anesthesia device is in a transport or storage waiting state, and use the binding assembly to ensure the anesthesia mask is in a stable position and posture. In other words, it provides a dedicated mounting point for the anesthesia mask, achieving integrated storage.

[0020] In one alternative embodiment, the binding assembly includes a resilient fastener, a hook, and a connector. One end of the resilient fastener is fixed to one side of the cover plate; the hook is installed at the other end of the resilient fastener; and the connector is located on the other side of the cover plate for engaging with the hook.

[0021] Beneficial effects: By using a binding assembly including hooks and connectors, the hooks engage with the connectors during installation. This hook-and-connector engagement eliminates the need for complex alignment or rotation. Operators simply hook the hook into the connector to secure it and remove it to release it, achieving one-click locking and one-click unlocking, shortening the time required to secure and retrieve the anesthesia mask in its stored state. Furthermore, by using elastic fasteners to connect the hooks and the cover, when the hooks are engaged with the connectors, the elastic fasteners are in a stretched state. Their recoil force continuously pulls the anesthesia mask towards the cover, securing it firmly to the support column. This automatically compensates for minor loosening caused by vibration or bumps, ensuring the anesthesia mask is always securely fixed without the need for repeated manual adjustments to the tightness.

[0022] In one alternative embodiment, the anesthesia device for large aquatic organisms further includes a storage base frame, a sealing plate, a handle, and a storage box. The sealing plate is mounted on one side of the storage base frame; the handle is rotatably connected to the storage base frame; the storage box is slidably connected to the interior of the storage base frame, and the storage box is fixedly connected to the sealing plate.

[0023] Beneficial effects: By incorporating a sliding storage box inside the storage base frame, and with the box fixedly connected to the sealing plate, operators can simply pull the sealing plate to slide the box out of the storage base frame, exposing internal components (such as tubing) for quick and easy access. In other words, the pull-out design reduces the difficulty of operation for operators. Furthermore, the rotating handle attached to the storage base frame allows operators to lift the entire anesthesia device. When not in use, the handle can be folded against the side of the storage base frame, reducing space occupancy and further optimizing the operator experience.

[0024] In one alternative embodiment, the anesthesia device for large aquatic organisms further includes a winding and clamping mechanism, which comprises a fixed post, a limiting straight plate, a pair of clamping plates, and a second elastic reset member. The fixed post, fixed to the inner bottom end of the storage box, is used for winding the tubing; the limiting straight plate is detachably connected to the top end of the fixed post; both clamping plates are slidably disposed on the limiting straight plate, and the pair of clamping plates are used to clamp the wound tubing; the second elastic reset member is used to drive at least one of the clamping plates to remain in a clamped state.

[0025] Beneficial effects: By setting a fixing post at the bottom of the storage box, the tubing (such as inlet tubes, suction tubes, and outlet tubes) is wound around its outer wall, achieving neatness and preventing multiple tubes from tangling, knotting, or twisting, thus facilitating quick retrieval. Furthermore, by setting a pair of clamps slidably mounted on a limiting plate and using a second elastic reset component, after the tubing is wound onto the fixing post, the pair of clamps move towards each other or at least one clamp moves towards the other under the action of the second elastic reset component, thereby clamping the bundled tubing, achieving automatic clamping and preventing the wound tubing from loosening. In addition, the winding and clamping mechanism is set at the bottom of the storage box, so that after the pipeline is wound and clamped, it can be pushed into the storage bottom frame along with the storage box for concealed storage. Pulling out the storage box will expose the winding and clamping mechanism for pipeline operation, forming an integrated design of winding, clamping and concealed storage, improving the efficiency of preparation and finishing before and after the use of the device.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] According to embodiments of the present invention, an anesthesia device for large aquatic organisms is provided, such as... Figure 1 As shown, it includes an anesthesia mechanism 1, a tightening and sealing mechanism 2, a support and binding mechanism 3, and a winding and clamping mechanism 8.

[0031] In one embodiment, such as Figure 1 , Figure 4 and Figure 7 As shown, the anesthesia device for large aquatic organisms also includes a storage base frame 4, a sealing plate 5, a handle 6, and a storage box 7.

[0032] The sealing plate 5 is installed on one side of the storage base frame 4; the handle 6 is rotatably connected to the storage base frame 4; the storage box 7 is slidably connected to the inside of the storage base frame 4, and the storage box 7 is fixedly connected to the sealing plate 5.

[0033] By setting a sliding storage box 7 inside the storage base frame 4, and fixing the storage box 7 to the sealing plate 5, the operator only needs to pull the sealing plate 5 to slide the storage box 7 out of the storage base frame 4, exposing its internal components (such as pipes), which are easy to access quickly.

[0034] That is, the pull-out structure reduces the difficulty of operation for operators. Furthermore, by rotating and connecting the handle 6 to the storage base frame 4, the operator can hold the handle 6 to lift the entire anesthesia device. When not in use, the handle 6 can be attached to the side of the storage base frame 4, reducing space occupation and further optimizing the operator's experience.

[0035] It can be explained that one side of the storage base frame 4 has an opening. During installation, the sealing plate 5 is movably connected to the opening of the storage base frame 4 to open or close the opening, so as to temporarily place the component inside the storage base frame 4 or temporarily remove the component from the storage base frame 4.

[0036] The outer edge of the storage box 7 is adapted to the inner wall of the storage base frame 4 to form a drawer-type structure.

[0037] Furthermore, such as Figure 7 As shown, the bottom of the storage box 7 is provided with at least one sliding block 701, and the inner bottom wall of the storage base frame 4 is provided with a matching groove 401, and the sliding block 701 is slidably installed in the groove 401.

[0038] Preferably, a pair of sliding blocks 701 are provided, and the sliding grooves 401 correspond one-to-one with the sliding blocks 701.

[0039] Among them, a pair of sliding blocks 701 are arranged at intervals.

[0040] It can be explained that, for example Figure 1 As shown, the anesthesia mechanism 1, the tightening and sealing mechanism 2, and the winding and clamping mechanism 8 are installed on the outside of the storage base frame 4, while the support and binding mechanism 3 is installed inside the storage box 7.

[0041] In one embodiment, such as Figures 1 to 3As shown, the anesthesia mechanism 1 includes an anesthesia cover 101, which is used to cover the head of the fish; the tightening and sealing mechanism 2 includes a flexible seal 201, a tightening member 202, and a locking assembly. The flexible seal 201 is disposed at the edge of the opening end of the anesthesia cover 101 and is used to conform to the contour of the fish head; the tightening member 202 is disposed around the outside of the anesthesia cover 101 and is used to apply a tightening force to drive the flexible seal 201 to press against the fish head; the locking assembly is used to keep the tightening member 202 in a tightened state.

[0042] By providing a flexible seal 201 at the edge of the opening of the anesthesia cover 101, it can undergo adaptive deformation when in contact with the fish's head, thereby closely fitting the irregular curved surface of the fish's head. This allows the anesthesia cover 101 to be applicable to a variety of different species and sizes of fish, without the need to design a separate sealing structure for each size.

[0043] Then, by using a tightening member 202 to surround the outside of the anesthesia cover 101 and in conjunction with a locking component to keep the tightening member 202 in a tightened state, in actual use, the tightening member 202 can apply a continuous and controllable radial tightening force to the anesthesia cover 101 and the flexible seal 201 on its edge, forcing the flexible seal 201 to press against the surface of the fish's head with greater pressure, effectively avoiding the unstable and insufficient sealing problems caused by relying solely on the weight of the cover or the operator's hand pressure in the prior art, and preventing the anesthetic fluid from leaking outward from the gap between the cover and the fish.

[0044] That is, the anesthetic fluid injected into the anesthesia hood 101 can be fully utilized for absorption by the fish's gills, thereby reducing the waste of anesthetic fluid.

[0045] It can be explained that, for example Figure 2 As shown, the anesthesia cover 101 has an anesthetic inlet 1011 and an anesthetic outlet 1012. Both the anesthetic inlet 1011 and the anesthetic outlet 1012 are connected to the internal cavity of the anesthesia cover 101. After the anesthesia cover 101 is placed over the head of the fish, the anesthetic enters the interior of the anesthesia cover 101 through the anesthetic inlet 1011 to anesthetize the fish, and then flows out from the anesthetic outlet 1012.

[0046] Furthermore, such as Figure 2 , Figure 4 and Figure 6As shown, the anesthesia device 1 also includes an anesthetic fluid storage tank 102, a peristaltic pump 103, an inlet pipe 104, a suction pipe 105, and an outlet pipe 106. The anesthetic fluid storage tank 102 is used to store anesthetic fluid; the peristaltic pump 103 is used to drive the movement of the anesthetic fluid; the inlet pipe 104 is connected between the discharge end of the peristaltic pump 103 and the anesthetic fluid inlet 1011 of the anesthesia mask 101; the suction pipe 105 is connected between the suction end of the peristaltic pump 103 and the anesthetic fluid storage tank 102; and the outlet pipe 106 is connected between the anesthetic fluid outlet 1012 of the anesthesia mask 101 and the anesthetic fluid storage tank 102.

[0047] By using an inlet pipe 104 connected between the discharge end of the peristaltic pump 103 and the anesthetic fluid inlet 1011 of the anesthesia mask 101, a suction pipe 105 connected between the suction end of the peristaltic pump 103 and the anesthetic fluid storage tank 102, and an outlet pipe 106 connected between the anesthetic fluid outlet 1012 of the anesthesia mask 101 and the anesthetic fluid storage tank 102, and using the peristaltic pump 103 to provide driving force, the anesthetic fluid can continuously flow along the path of the anesthetic fluid storage tank 102, suction pipe 105, inlet pipe 104, anesthesia mask 101, outlet pipe 106, and anesthetic fluid storage tank 102.

[0048] That is, the anesthetic fluid flowing out of the anesthesia hood 101 outlet is not directly discharged, but flows back into the storage tank to participate in the circulation again. Compared with the traditional immersion anesthesia or the drug administration method that is discarded after a single flow, the anesthetic fluid can be reused, reducing the amount of anesthetic fluid required for a single anesthesia operation, thereby saving consumable costs.

[0049] Meanwhile, since the tightening and sealing mechanism 2 can effectively block the leakage of anesthetic fluid from the gap between the anesthesia cover 101 and the fish body, an energy-saving anesthesia mechanism with low leakage and high recovery is constructed.

[0050] In addition, the anesthesia procedure can be completed on-site without the need to transport the fish or frequently replenish or change the anesthetic solution during the procedure, reducing human intervention and allowing a single person to complete the entire anesthesia process, thus lowering labor costs and simplifying the procedure.

[0051] It can be explained that, for example Figure 2 and Figure 4 As shown, one-way valves 109 are installed on the upstream side of the anesthetic fluid inlet 1011 and the downstream side of the anesthetic fluid outlet 1012 to prevent anesthetic fluid backflow and thus avoid affecting the anesthetic fluid recycling process.

[0052] It can be noted that the anesthetic fluid storage tank 102 is equipped with a dispensing port and a return port.

[0053] During installation, the two connection ports of the inlet pipe 104 are respectively connected to the anesthetic fluid inlet 1011 and the discharge end of the peristaltic pump 103 through pipe joints. The two connection ports of the suction pipe 105 are respectively connected to the suction end of the peristaltic pump 103 and the outlet port of the anesthetic fluid storage tank 102 through pipe joints. The two connection ports of the outlet pipe 106 are respectively connected to the anesthetic fluid outlet 1012 and the return port of the anesthetic fluid storage tank 102 through pipe joints.

[0054] It can be explained that, for example Figure 1 and Figure 4 As shown, the bottom of the peristaltic pump 103 and the bottom of the anesthetic fluid storage tank 102 are each provided with at least one mounting plate 9. The mounting plate 9 is provided with a through hole, and the top of the storage base frame 4 is provided with a threaded hole. During installation, fasteners with external threads, such as bolts, are passed through the through hole and screwed into the threaded hole until they are tightened, thereby fixing the peristaltic pump 103 and the anesthetic fluid storage tank 102 to the top of the storage base frame 4.

[0055] Preferably, the mounting plates 9 at the bottom of the peristaltic pump 103 are arranged in pairs, and the mounting plates 9 at the bottom of the anesthetic fluid storage tank 102 are arranged in pairs, which can be one pair, two pairs or more.

[0056] Specifically, when there are two or more pairs of mounting pieces 9, the mounting pieces 9 of adjacent pairs are arranged at intervals to make the peristaltic pump 103 and the anesthetic fluid storage tank 102 more reliable after installation, and to avoid the phenomenon that the fixed posture deviates from the expected due to the loosening of the mounting pieces 9 when the number is small.

[0057] It can be noted that the anesthesia mask 101 is made of acrylic material, and the ring frame 207 is made of nitrile rubber flexible material. The whole is conical in shape, and its tip is blunt and rounded to avoid injury to the operator.

[0058] In one embodiment, such as Figure 1 and Figure 4 As shown, at least one grip ring 108 is installed on the outer wall of the anesthesia mask 101, which is for the operator to hold manually.

[0059] Preferably, a pair of grip rings 108 are provided, and the pair of grip rings 108 are arranged opposite to each other on the outer wall of the anesthesia mask 101.

[0060] The grip ring 108 is curved to improve the comfort of operators when manually gripping it.

[0061] In one embodiment, such as Figures 1 to 3 As shown, the tightening and sealing mechanism 2 also includes an annular frame 207, which is installed at the open end of the anesthesia mask 101; the flexible seal 201 is embedded in the inner side of the annular frame 207.

[0062] By adding an annular frame 207 to the opening end of the anesthesia cover 101 and embedding the flexible seal 201 inside the annular frame 207, the annular frame 207, as a rigid or semi-rigid skeleton, can provide all-round structural support for the flexible seal 201, ensuring that the flexible seal 201 always maintains the predetermined posture when it is fitted onto the fish's head, and will not curl, fold or shift due to its own weight, anesthetic fluid pressure or friction with the fish's head, so that the flexible seal 201 can always be aligned with the area to be sealed on the fish's head, avoiding the phenomenon of local leakage caused by the displacement of the seal.

[0063] Meanwhile, the annular frame 207 serves as a rigid load-bearing layer. When the tightening member 202 (such as an elastic band) applies a tightening force around the outside of the anesthesia mask 101, the tightening force will directly act on the annular frame 207 at the opening end of the anesthesia mask 101, and then be evenly transmitted to the flexible sealing member 201 embedded inside it. This avoids the phenomenon of uneven sealing pressure distribution caused by the deformation of the anesthesia mask 101 body due to the absence of the annular frame 207.

[0064] It can be explained that, for example Figure 2 As shown, a soft silicone sealing layer 208 is provided at the annular frame 207. Since the soft silicone sealing layer has high elasticity, it can adapt to the deformation of the fish head contour, and is used to flexibly fit the fish head contour, and can completely fill the gap between the annular frame 207 and the fish head.

[0065] In one embodiment, it remains as follows Figures 1 to 3 As shown, the tightening and sealing mechanism 2 also includes a support frame 209, which is installed on the outer wall of the flexible seal 201. The annular frame 207, the support frame 209 and the flexible seal 201 are all provided with through holes, which are used to be sleeved on the outside of the tightening member 202 during installation, and to make the inner wall of the through hole contact the outer wall of the tightening member 202.

[0066] The tightening and sealing mechanism 2 also includes an inner support member 211. During installation, the inner support member 211 is fixedly installed on the inner wall of the support frame 209, and the inner support member 211 and the support frame 209 form an movable gap for accommodating the tightening member 202 and allowing for length adjustment. At the same time, the inner support member 211 is located on the inner wall side of the tightening member 202 to support the tightening member 202 from the inside.

[0067] Preferably, such as Figure 3 As shown, the inner support member 211 has a U-shaped or Z-shaped structure with protrusions.

[0068] Specifically, the inner support member 211 includes an end wall and two side walls. The two side walls are respectively connected to both ends of the end wall and extend to the same side, thereby forming a protrusion. During installation, the side walls of the protrusion are used to contact the inner wall side of the fastening member 202; the end wall is fixedly connected to the inner wall of the support frame 209. In this way, the fastening member 202 is confined within the movable gap between the outer side of the protrusion and the inner wall of the support frame 209, and can slide freely within this gap to adjust the fastening length, while the protrusion maintains its circumferential position stability.

[0069] In one embodiment, such as Figure 2 and Figure 3 As shown, the fastening member 202 is elastic and includes a fastening section 2021 and an adjusting section 2022 connected to each other; the locking assembly includes a pair of pressing plates 203, a driving member 204 and a first elastic reset member 205.

[0070] A pair of extrusion plates 203 are symmetrically arranged on opposite sides of the adjustment section 2022; the driving member 204 is connected to at least one extrusion plate 203 for driving the pair of extrusion plates 203 to move closer to each other or away from each other; one end of the first elastic reset member 205 is connected to or abuts against the driving member 204, and the other end acts on the extrusion plate 203.

[0071] In use, under the action of external force, the driving member 204 drives a pair of pressing plates 203 to move away from each other, so that the length of the adjusting section 2022 can be freely adjusted, and the first elastic reset member 205 stores energy. When the external force is removed, the first elastic reset member 205 releases energy, drives a pair of pressing plates 203 to move closer to each other and press the adjusting section 2022, locking the tightening length of the tightening member 202.

[0072] By making the fastening member 202 elastic and dividing it into a fastening section 2021 and an adjusting section 2022, the locking assembly includes a pair of compression plates 203 that can move closer to each other or further apart. When an external force causes the pair of compression plates 203 to move further apart through the driving member 204, the adjusting section 2022 can move freely. The operator can continuously and steplessly adjust the extension length of the adjusting section 2022 according to the actual circumference of the fish's head, thereby changing the overall fastening circumference of the fastening member 202 to accurately match the application requirements of different fish head contours.

[0073] After the external force is removed, the first elastic reset member 205 releases energy and drives a pair of compression plates 203 to move closer to each other, directly pressing the adjustment section 2022 to achieve automatic locking. This ensures that the tightening member 202 maintains the set tightening length throughout the entire anesthesia operation cycle, thereby maintaining a constant pressure between the flexible seal 201 and the fish head, avoiding the risk of anesthetic leakage due to accidental loosening of the tightening member 202, and improving the reliability of the seal.

[0074] It can be explained that, for example Figure 2 and Figure 3 As shown, the drive component 204 includes a handle 2041 and a movable rod 2042.

[0075] One end of the movable rod 2042 is fixed to the handle 2041, and the other end of the movable rod 2042 is fixedly connected to the extrusion plate 203; wherein, pulling the handle 2041 can drive the extrusion plate 203 away from the fastening member 202.

[0076] By fixing the movable rod 2042 to the handle 2041, the operator only needs to pull the handle 2041 by hand, and the movable rod 2042 will drive the compression plate 203 to move linearly away from the fastening member 202, thereby releasing the compression plate 203 from the fastening member 202 (adjustment section 2022). When it is necessary to adjust the fastening length of the fastening member 202, the operator can simultaneously complete the pulling action (unlocking) and the action of tightening or loosening the fastening member 202 with one hand. After the adjustment is in place, the handle 2041 is released, and the first elastic reset member 205 can automatically push the compression plate 203 to reset and lock.

[0077] That is, it enables a pull-to-release and release-to-lock operation mode, allowing for quick unlocking.

[0078] The first elastic reset member 205 is a linear spring. During installation, the two ends of the first elastic reset member 205, which are axially opposite to each other, are respectively connected to the inner walls of the extrusion plate 203 and the support frame 209.

[0079] Furthermore, the number of movable rods 2042 on each driving member 204 is not specifically limited, and can be one, two or more. In this case, the number of first elastic reset members 205 installed on each driving member 204 is the same as the number of movable rods 2042, that is, each movable rod 2042 is fitted with a first elastic reset member 205.

[0080] It should be noted that the movable rod 2042 passes through the side wall of the support frame 209. The end of the movable rod 2042 inside the support frame 209 is connected to the extrusion plate 203, and the end of the movable rod 2042 outside the support frame 209 is connected to the handle 2041.

[0081] It can be explained that, for example Figure 2 and Figure 3 As shown, an anti-slip component 206 is fixedly installed on the side of the extrusion plate 203 facing the adjustment section 2022.

[0082] By fixing an anti-slip element 206 on the side of the extrusion plate 203 facing the adjustment section 2022, when a pair of extrusion plates 203 approach each other and press the adjustment section 2022 under the action of the first elastic reset element 205, the anti-slip element 206 directly contacts the surface of the adjustment section 2022. Compared with the smooth surface of the extrusion plate 203, the anti-slip element 206 can significantly improve the static friction coefficient between the two, thereby effectively resisting the longitudinal tension that the adjustment section 2022 may be subjected to in the tightened state, ensuring that even under dynamic load, the adjustment section 2022 is unlikely to slip relative to each other, thereby maintaining the tightening length set by the tightening element 202 without change, and avoiding the decrease in sealing performance caused by slippage.

[0083] Preferably, a pair of extrusion plates 203 are respectively arranged on one of the opposite sides of the support frame 209, and each side is provided with a plurality of movable rods 2042, a plurality of first elastic reset members 205, and an anti-slip member 206.

[0084] It can be explained that the anti-slip component 206 is composed of several anti-slip extrusion strips spliced ​​together to make close contact with the outer wall of the fastening component 202.

[0085] The anti-slip extrusion strip is made of rubber with longitudinal anti-slip textures on its surface. When it comes into contact with the outer wall of the adjustment section 2022, the textures embed into the fiber gaps of the adjustment section 2022, thereby increasing friction and enhancing the anti-slip effect. Even if the fish struggles slightly, the high friction will ensure that the adjustment section 2022 will not slip, thus maintaining a stable sealing pressure.

[0086] It can be explained that, for example Figure 1 and Figure 4 As shown, the anesthetic fluid storage tank 102 has an opening at the top and a cover plate 107 is provided to cover the opening.

[0087] During installation, the cover plate 107 is sealed to the opening at the top of the anesthetic fluid storage tank 102 by fasteners (such as bolts) to separate the interior of the anesthetic fluid storage tank 102 from the external environment.

[0088] In practical applications, an oxygenation pump (such as the SP-600 miniature oxygenation pump) can be installed inside the anesthetic fluid storage tank 102 to ensure that the oxygen content in the input anesthetic is not less than 8.0 mg / L.

[0089] Among them, the peristaltic pump 103 adopts the BT100L-V3 flow-type intelligent peristaltic pump 103, which, together with the YZ15 pump head, realizes the flow control function and adjusts the input volume of anesthetic fluid (such as motor speed, tubing diameter, pressure adjustment, etc.). If it is used for Chinese sturgeon with a size of 120cm to 150cm, the YZ15 pump head and 8mm inner diameter fluororubber tubing can be selected, and the speed is set to 30rpm to 50rpm, corresponding to a flow rate of 10mL / min to 20mL / min, to ensure that the concentration of anesthetic fluid is stable at 50mg / L to 80mg / L.

[0090] It can be explained that, for example Figure 1 , Figure 4 and Figure 5 As shown, the support and binding mechanism 3 includes a support column 301 and a binding assembly. The support column 301 is fixedly mounted on the cover plate 107 for mounting the anesthesia mask 101; the binding assembly is mounted on the cover plate 107 for binding and fixing the anesthesia mask 101.

[0091] A support column 301 is provided on the cover plate 107 of the anesthetic fluid storage tank 102 to support the anesthesia mask 101, and a binding assembly is further provided to bind the anesthesia mask 101 to the support column 301. When the anesthesia device is in a waiting state such as for transfer or storage, the operator can directly put the anesthesia mask 101 on or insert it onto the support column 301 and use the binding assembly to ensure that the anesthesia mask 101 is in a stable position and posture.

[0092] That is, a dedicated mounting site is provided for the anesthesia mask 101 to achieve integrated storage.

[0093] It should be noted that when the device is idle or being transported, the open end of the anesthesia mask 101 is facing downwards and is fitted onto the support column 301 until the smooth head of the support column 301 contacts the inner top of the anesthesia mask 101 to provide support and prevent the anesthesia mask 101 from collapsing or deforming due to its own weight or compression.

[0094] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the binding assembly includes an elastic fastener 302, a hook 303, and a connector 304.

[0095] One end of the elastic fastener 302 is fixed to one side of the cover plate 107; the hook 303 is installed on the other end of the elastic fastener 302; the connector 304 is provided on the other side of the cover plate 107 and is used to hook and cooperate with the hook 303.

[0096] By using a binding assembly including a hook 303 and a connector 304, the hook 303 and connector 304 are hooked together during installation. This hooking method eliminates the need for complex alignment or rotation. The operator only needs to hook the hook 303 onto the connector 304 to secure it and remove the hook 303 from the connector 304 to release it. This achieves locking with a simple hook and unlocking with a simple detach, shortening the time required to secure and retrieve the anesthesia mask 101 in its stored state.

[0097] Then, by using the elastic fastener 302 to connect the hook 303 and the cover plate 107, when the hook 303 is hooked onto the connector 304, the elastic fastener 302 is in a stretched state, and its retraction force will continuously pull the anesthesia mask 101 toward the cover plate 107, so that the anesthesia mask 101 is fastened to the support column 301, automatically compensating for the slight loosening caused by vibration or bumps, ensuring that the anesthesia mask 101 is always firmly fixed without the need for manual and repeated adjustment of the tightness.

[0098] It can be explained that, for example Figure 4 and Figure 5 As shown, connector 304 adopts a lug structure.

[0099] Preferably, the connectors 304 are arranged in pairs. When the anesthesia cover 101 is installed, one end of the elastic fastener 302 is tied to one of the connectors 304, and the other end of the elastic fastener 302 passes through the grip ring 108 and is connected to a hook 303. The hook 303 is used to hook onto the lug.

[0100] In one embodiment, such as Figure 1 and Figure 8 As shown, the winding clamping mechanism 8 includes a fixed post 801, a limiting straight plate 802, a pair of clamping plates 803, and a second elastic reset member 804.

[0101] The fixing post 801 is fixed to the inner bottom end of the storage box 7 and is used to wind the pipe; the limiting straight plate 802 is detachably connected to the top of the fixing post 801; a pair of clamping plates 803 are slidably disposed on the limiting straight plate 802 and are used to clamp the wound pipe; the second elastic reset member 804 is used to drive at least one clamping plate 803 to keep it in a clamped state.

[0102] By setting a fixing post 801 at the bottom of the storage box 7, the pipes are allowed to be wound around its outer wall, which can achieve neatness and avoid multiple pipes from getting tangled, knotted or twisted, thus providing convenience for quick access later.

[0103] Then, by setting a pair of clamping plates 803 to slide on the limiting straight plate 802, and using the second elastic reset member 804, after the pipeline is wound on the fixed column 801, the pair of clamping plates 803 move closer to each other or at least one clamping plate 803 moves towards the other clamping plate 803 under the action of the second elastic reset member 804, thereby clamping the bundled pipeline, that is, realizing automatic clamping and preventing the wound pipeline from loosening.

[0104] In addition, the winding and clamping mechanism 8 is set at the bottom of the storage box 7, so that after the pipeline is wound and clamped, it can be pushed into the storage bottom frame 4 along with the storage box 7 for concealed storage. Pulling out the storage box 7 will expose the winding and clamping mechanism 8 for pipeline operation, forming an integrated design of winding, clamping and concealed storage, improving the efficiency of preparation and finishing before and after use of the device.

[0105] The pipeline includes an inlet pipe 104, a suction pipe 105, and an outlet pipe 106.

[0106] It can be explained that, for example Figure 8 As shown, a sponge block 807 is installed on the side of the clamp 803 that is in contact with the pipeline to prevent the rigid clamp 803 from directly squeezing the pipeline and to prevent damage or deformation of the pipeline wall.

[0107] It can be noted that the number of winding and clamping mechanisms 8 is set in proportion to the number of pipelines.

[0108] For example, the number of winding clamping mechanisms 8 is the same as the number of pipelines.

[0109] At this time, the winding clamping mechanism 8 is provided with three sets. The three fixed columns 801 in the three sets of winding clamping mechanisms 8 are respectively used for winding the liquid inlet pipe 104, the suction pipe 105 and the liquid outlet pipe 106.

[0110] Of course, to improve the integration of the internal components of the storage box 7, the liquid inlet pipe 104, the suction pipe 105 and the liquid outlet pipe 106 are wound around the same fixed post 801.

[0111] It can be noted that the second elastic reset member 804 is preferably a linear spring.

[0112] It can be explained that, for example Figure 8 As shown, the limiting straight plate 802 has a pair of guide grooves 8021. Each guide groove 8021 is equipped with a horizontally arranged cylindrical guide rod 805. Each cylindrical guide rod 805 is slidably connected to a movable sleeve block 806. A pair of clamping plates 803 are respectively fixedly installed at the bottom of the pair of movable sleeve blocks 806. The number of second elastic reset members 804 is the same as the number of cylindrical guide rods 805. During installation, the second elastic reset members 804 are sleeved on the outside of the cylindrical guide rods 805, and their two ends abut against the movable sleeve block 806 and the inner wall of the guide groove 8021 respectively along the direction of their elastic deformation.

[0113] The installation process for anesthesia devices used on large aquatic organisms includes: The prepared anesthetic solution is filled into the anesthetic solution storage tank 102, and the cover plate 107 is installed to achieve sealed storage. Then, the anesthetic cover 101 and the annular frame 207 are placed on the fish's head, and the handles 2041 on both sides are moved apart, causing the movable rods 2042 on both sides to move apart at the support frame 209, so that the compression plates 203 on both sides move away from the fastening member 202. During this process, the first elastic reset member 205 is compressed, and the length of the adjustment section 2022 is adjusted freely until it is tightened, so that the annular frame 207 can be in close contact with the fish's head. Then, the handles 2041 on both sides are released, the first elastic reset member 205 is reset, and the movable rods 2042 and the compression plate 203 on both sides are reset, until the compression plates 203 on both sides contact and squeeze the adjustment section 2022, thereby maintaining the tightness of the fixed fastening member 202, so that the anesthetic cover 101 and the annular frame 207 are sealed with the fish's head.

[0114] Then, the peristaltic pump 103 is activated, and the anesthetic fluid in the anesthetic fluid storage tank 102 is drawn through the suction tube 105. The fluid then flows through the inlet tube 104 into the anesthetic hood 101 until it is full. This allows the anesthetic fluid to enter from the fish's mouth and flow out through the gills, thus achieving anesthesia. During this process, the anesthetic fluid flowing out through the gills and the anesthetic fluid not inhaled by the fish's mouth will flow back to the anesthetic fluid storage tank 102 through the outlet tube 106. This process is repeated to drive the reuse of the anesthetic fluid.

[0115] After anesthesia is completed, the inlet tube 104, suction tube 105 and outlet tube 106 are disassembled, and the peristaltic pump 103 and anesthetic fluid storage tank 102 are fixed on the storage base frame 4. The removed anesthesia mask 101 is then placed with its open end facing down on the support column 301. One end of the elastic fastener 302 is tied to the connector 304 on one side of the cover plate 107, and the other end passes through the grip ring 108 outside the anesthesia mask 101 and is hooked to the connector 304 on the other side by the hook 303. The anesthesia mask 101 is fixed to the support column 301 by the tension of the elastic fastener 302 itself.

[0116] Next, the pipeline is wound around the fixed post 801. First, along the guide of the cylindrical guide rod 805, a movable sleeve 806 is moved away from another movable sleeve 806 in the corresponding guide groove 8021, so as to drive the two clamping plates 803 to separate. During this process, the second elastic reset member 804 is compressed and stores energy. After the winding is completed, the external force acting on the movable sleeve 806 is removed. The second elastic reset member 804 resets and releases energy, which will drive the movable sleeve 806 to move closer to the other movable sleeve 806 in the guide groove 8021 along the guide of the cylindrical guide rod 805, so as to drive the clamping plate 803 to clamp the pipeline wound on the fixed post 801.

[0117] Then slide the storage box 7 into the storage base frame 4, and complete the binding and fixing of the anesthesia mask 101. Then fix the peristaltic pump 103 and the anesthetic fluid storage tank 102 on the cover plate 107 to complete the installation. Then turn the handle 6 to carry the device.

[0118] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
