Abstract
Description
Technical Field
[0001] This application relates to the technical field of hirudin extraction auxiliary equipment, and in particular to a high-efficiency hirudin extraction device. Background Technology
[0002] Hirudin is the most active and extensively studied component among the various active ingredients extracted from leeches and their salivary glands. It is a small protein molecule composed of 65-66 amino acids. Leeches are rich in hirudin, which has a very strong inhibitory effect on thrombin, making it the strongest naturally occurring specific inhibitor of thrombin discovered to date. Traditional extraction methods mainly involve relatively stimulating methods such as squeezing or electrocution to induce leech saliva secretion. These methods yield relatively little hirudin and can cause some damage to the leeches themselves during the process.
[0003] Chinese patent CN221956007U discloses a hirudin extraction device, including an extraction box with a connection port on one side of the box. A sliding plate slides horizontally inside the extraction box, and a first sliding mechanism is provided inside the box. A placement groove is formed through the top of the extraction box, and two mesh screens slide horizontally inside the sliding plate, each screen being placed inside the placement groove. A second sliding mechanism is provided inside the plate to slide the two mesh screens. An electric telescopic rod is fixedly connected to the top of the extraction box, and a pressing plate is installed at the bottom of the rod. The pressing plate cooperates with the placement groove. This patent allows the leeches to be extracted to be placed in the placement groove using the sliding plate. The sliding plate is then slid into the extraction box, and the pressing plate inside the extraction box, in cooperation with the placement groove, presses the leeches, thereby extracting hirudin from them.
[0004] Chinese patent CN217997063U discloses an induction device for extracting hirudin, including an emetic induction mechanism. A first pump has an inlet pipe connected to its inlet end and an outlet pipe fixedly connected to its outlet end. The end of the outlet pipe away from the first pump is fixedly connected to an induction liquid curved spray pipe. A positioning plate is also fixedly installed on the inner wall of an emetic storage and sealing box. A leech placement trough plate is movably hinged to one end of the positioning plate, and a material guide hole is opened at one end of the leech placement trough plate. This patent uses a biomimetic induction method to induce live leeches, minimizing the need to kill the leeches and allowing for their reuse. After removing the leeches, a primary extract can be obtained through separation and extraction, quickly yielding hirudin secreted from leech saliva.
[0005] However, the above methods all use a single treatment method when stimulating leeches, such as inducing vomiting or squeezing. Such extraction methods can only make leeches secrete a certain amount of hirudin when vomiting or squeezing is induced, but cannot improve the efficiency of leech saliva secretion, thus the hirudin extraction efficiency will be low. At the same time, there is no related spraying mechanism to spray or wash the secretions containing hirudin attached to the box, which further reduces the collection rate of hirudin. Utility Model Content

By adjusting the length of the spray assembly, spraying can be applied at different heights within the extraction chamber, effectively improving the hirudin collection rate. Simultaneously, several protruding plates are installed in the placement tank. When leeches move within the tank, the protruding plates scrape away secretions from the leeches' bodies and stimulate them, promoting saliva secretion. An emetic is then introduced into the placement tank through an input channel to induce vomiting in the leeches. This combination of stimulation methods allows for hirudin extraction, improving extraction efficiency without harming the leeches.

[0041] refer to Figure 1-5 This application discloses an efficient extraction device for hirudin, comprising:
[0042] Extraction box 1, which is a box with an opening, has a first sliding groove 11 arranged horizontally on the left side plate inside the extraction box 1, and a second sliding groove 12 arranged horizontally on the right side plate inside the extraction box 1. The first sliding groove 11 and the second sliding groove 12 are arranged symmetrically. A retractable spray assembly 2 is fixedly connected to the top of the extraction box 1. An input channel 13 is provided on one side of the extraction box 1.
[0043] Placement trough 4 is located inside extraction box 1 and is slidably connected to first slide 11 and second slide 12. Placement trough 4 is provided with transmission hole 41 and input channel 13 is connected to placement trough 4 through transmission hole 41. Several protruding plates 42 are evenly provided on the bottom plate of placement trough 4. Infusion hole 43 is provided on the bottom plate of placement trough 4.
[0044] The collection tank 5 is located below the extraction box 1. An output channel 3 is provided below the collection tank 5. The collection tank 5 is connected to the lower end of the infusion port 43.
[0045] In this configuration, the placement trough 4 is slidably connected to the first sliding groove 11 and the second sliding groove 12, allowing the placement trough 4 to be pulled out relative to the extraction box 1. After pulling the placement trough 4 out relative to the extraction box 1, a fed leech is placed into the placement trough 4. Then, the placement trough 4 is pushed back into the extraction box 1, allowing the leech to swim within it. This causes the convex plate 42 to scrape the leech's initial secretions. Subsequently, an emetic is introduced into the placement trough 4 through the input channel 13 to induce vomiting in the leech. Due to the effect of the emetic, the leech will swim within the placement trough 4, and the convex plate 42 will scrape away the leech's secretions. The presence of the emetic will provide additional stimulation to the swimming leeches, further promoting their vomiting and secretion. The vomit and secretions, along with the liquid in the container, are fed into the collection tank 5 through the infusion port 43. After a period of treatment, the infusion of the emetic is stopped. Then, the height of the spray assembly 2 is adjusted, and the spray assembly 2 is turned on to spray the leeches in the placement tank 4 and the inner surface of the placement tank 4. Subsequently, the liquid enters the collection tank 5 through the infusion port 43. After treatment is completed, the spray assembly 2 is turned off, the placement tank 4 is removed, and the leeches are moved back into the breeding pond. Finally, the liquid in the collection tank 5 is discharged through the output channel 3, and the height of the spray assembly 2 is adjusted again to spray the inside and outside of the collection tank 5, causing the secretions attached to the collection tank 5 to be discharged with the water flow.
[0046] Therefore, in the above-mentioned device, by setting up a retractable spray assembly 2, the length of the spray assembly 2 can be adjusted to achieve spraying at different heights within the extraction chamber 1. The first spray hole 211 and the second spray hole can collect the hirudin-containing secretions from the surfaces of the attachment placement tank 4 and the collection tank 5, effectively improving the hirudin collection rate. The protruding plate 42 can scrape off the secretions as the leeches move, providing a certain stimulation to the leeches and promoting saliva secretion. After adding an emetic, it promotes vomiting in the leeches. The combination of these two stimulation methods improves the extraction efficiency of hirudin.
[0047] Specifically, the height of the convex plate 42 is 0.5-0.8cm, and the length of the convex plate 42 is 1.2-1.8cm.
[0048] Specifically, the material of the convex plate 42 is not specifically limited, as long as it is a rigid material. It can be a metal material, such as iron, aluminum or steel, or a polymer material, such as polyethylene, polypropylene or polytetrafluoroethylene.
[0049] Specifically, the diameter of the infusion hole 43 is designed to prevent leeches from leaking out and from entering the collection tank 5 through the infusion hole 43.
[0050] As one embodiment, it also includes a straight rod 422, a limiting member 421 and a limiting ring 423. One end of the straight rod 422 is fixedly connected to the base plate, and the other end of the straight rod 422 is fixedly connected to the limiting member 421. The protruding plate 42 is sleeved on the straight rod 422 and can rotate relative to the straight rod 422. The limiting ring 423 is disposed below the protruding plate 42.
[0051] refer to Figure 4 In this configuration, the convex plate 42 can rotate relative to the straight rod 422. When a larger leech swims across the convex plate 42 in the placement groove 4, the secretions on the leech's skin can be scraped from above the convex plate 42. When a smaller leech passes under the convex plate 42, because the convex plate 42 has a double trapezoidal structure, there will be a large gap at the end near the straight rod 422, allowing the smaller leech to pass through. In addition, the limiting ring 423 is a certain distance away from the convex plate 42. When the leech passes under the convex plate 42, it can also lift the convex plate 42, thereby achieving the scraping of the leech's skin secretions. Furthermore, due to the trapezoidal structure, the contact area between the convex plate 42 and the leech is large, thus achieving better scraping of secretions. When leeches are swimming on both sides of the convex plate 42, due to the rotatable configuration of the convex plate 42, the secretions on the surface of the leech's skin can be scraped from both sides of the convex plate 42 simultaneously. In addition, when the convex plate 42 rotates, it can stimulate the surrounding leeches. The setting of one convex plate 42 can stimulate multiple leeches in the placement tank 4, thereby promoting multiple leeches to secrete secretions containing hirudin.
[0052] The limiting component 421 can prevent the convex plate 42 from detaching from the straight rod 422, extend the service life and safety of the convex plate 42, and prevent the convex plate 42 from falling off.
[0053] In one implementation, the convex plate 42 is provided with a plurality of protrusions 424. With this configuration, when the leeches swim in the placement tank 4, the surface of the leeches can be massaged, preventing the convex plate 42 from causing excessive stimulation to the leeches themselves, which would affect the leeches' swimming or feeding. By providing protrusions 424 on the convex plate 42, a soothing effect can be achieved, preventing the leeches from dying.
[0054] Specifically, the height of protrusion 424 is 0.05-0.1cm.
[0055] Specifically, the material of the 424 protrusion is not specifically limited. It can be a flexible soft material, such as silicone or rubber, or a hard material, such as metal or polymer.
[0056] In one embodiment, the spray assembly 2 includes a fixed rod 22 and a spray plate 21. The fixed rod 22 is provided with a retractable hose 221. The upper end of the retractable hose 221 is fixedly connected to the water tank, and the lower end of the retractable hose 221 is fixedly connected to the spray plate 21. The lower surface of the spray plate 21 is uniformly provided with first spray holes 211, and the spray plate 21 is uniformly provided with second spray holes 212 around its circumference.
[0057] In this setting, the length of the pull-out hose 221 can be adjusted to adjust the height of the spray plate 21. When the length of the pull-out hose 221 is adjusted so that the spray plate 21 is in the placement tank 4, the first spray hole 211 on the spray plate 21 can spray the leeches on the bottom plate of the placement tank 4 and the second spray hole 212 on the spray plate 21 can spray the inner circumferential side of the placement tank 4, thereby improving the spraying efficiency and allowing the hirudin in the placement tank 4 to enter the collection tank 5 with the water flow. After spraying the placement tank 4, remove the placement tank 4, adjust the length of the pull-out hose 221 so that the spray plate 21 is inside the collection tank 5, release the liquid in the collection tank 5, and use the spray plate 21 to spray the inside of the collection tank 5 to clean the collection tank 5. The spray plate 21 is provided with a first spray hole 211 and a second spray hole 212 to improve the spraying efficiency. If only the first spray hole 211 is provided, it may only effectively clean the bottom of the placement tank 4 and the collection tank 5, and cannot effectively clean the circumferential area inside the placement tank 4 and the collection tank 5.
[0058] Specifically, the water tank is located outside the extraction box 1. It can be placed above the extraction box 1 or to the side of the extraction box 1, as long as it can be connected to the pull-out hose 221.
[0059] In one implementation, the second spray holes 212 are in at least two rows. With this configuration, the second spray holes 212 can better spray the inner circumferential surfaces of the placement tank 4 and the collection tank 5.
[0060] In one implementation, the angle between the spray direction of the second spray holes 212 and the horizontal axis differs between adjacent rows. This difference in angle ensures that the second spray holes 212 in adjacent rows can spray at multiple angles, improving spray coverage and thus spray efficiency. Specifically, the spray directions of the second spray holes 212 in two adjacent rows can be symmetrically arranged relative to the horizontal axis. With this arrangement, simultaneous spraying can be achieved at the upper and lower ends of the inner side of the placement groove 4, effectively improving spray efficiency.
[0061] In one embodiment, a feeding hole 44 is provided at the bottom end of the placement tank 4 near the opening, and a push-pull feeding trough 6 is provided in the feeding hole 44. The feeding trough 6 can slide relative to the bottom plate of the placement tank 4. In this configuration, the feeding trough 6 is detachable from the placement tank 4. When it is necessary to feed the leeches, the feeding trough 6 is placed into the feeding hole 44 and pushed into the placement tank 4 to feed the leeches. After feeding for a certain period of time, the feeding trough 6 is removed to prevent the leeches from being overfed, which would affect the subsequent extraction of hirudin.
[0062] In one embodiment, a first sealing plate 7 is also provided inside the placement groove 4. The first sealing plate 7 is slidably connected to the placement groove 4 and is used to seal the feeding hole 44. In this configuration, when the feeding trough 6 enters the feeding hole 44, the first sealing plate 7 is first lifted upwards, the feeding hole 44 is opened, the feeding trough 6 is placed in and pushed in for feeding. At this time, the bottom of the first sealing plate 7 is located at the upper end of the feeding trough 6, and the feeding trough 6 supports the first sealing plate 7. After feeding, the first sealing plate 7 is lifted, the feeding trough 6 is taken out of the feeding hole 44, and then the first sealing plate 7 is released, the first sealing plate 7 descends, thereby sealing the feeding hole 44.
[0063] Specifically, the sliding connection between the first sealing plate 7 and the placement groove 4 is not specifically limited. A slide rail can be set on the placement groove 4 to realize the movement of the first sealing plate 7. Alternatively, a vertical adjustment hole can be set at the position corresponding to the placement groove 4 and the first sealing plate 7. A handle that cooperates with the adjustment hole is set on the first sealing plate 7. The up and down movement of the first sealing plate 7 can be realized by cooperating the handle with the adjustment hole.
[0064] In one embodiment, a screen (not shown in the figure) is provided in the infusion port 43. This setting can further prevent leeches from entering the collection tank 5, and can also effectively filter out some large particulate impurities in the liquid, ensuring the quality of hirudin, while preventing leeches from falling out and improving the safety of the device.
[0065] In one embodiment, a second sealing plate 8 is provided at the lower end of the placement tank 4. The second sealing plate 8 can slide relative to the bottom plate of the placement tank 4 and is used to seal the infusion hole 43. With this configuration, before the emetic is introduced, the infusion hole 43 on the placement tank 4 is sealed by the second sealing plate 8. Subsequently, the emetic is introduced, and the emetic can be stored in the placement tank 4 to induce vomiting in leeches, thereby improving the efficiency of emetic induction.
[0066] Specifically, there is a certain gap between the lower end of the placement groove 4 and the collection groove 5, which allows the second sealing plate 8 to slide relative to the bottom plate of the placement groove 4.
[0067] Specifically, the sliding connection between the second sealing plate 8 and the placement groove 4 is not specifically limited. For example, sliding grooves can be provided on the left and right sides of the bottom of the placement groove 4 to enable the second sealing plate 8 to slide and seal the infusion hole 43 on the placement groove 4. Alternatively, sliding brackets can be provided at the bottom of the placement groove 4 near the opening and away from the opening, respectively, and the second sealing plate 8 can be placed on the sliding brackets to enable the second sealing plate 8 to slide and seal the infusion hole 43 on the placement groove 4.
[0068] Specifically, the sliding of the second sealing plate 8 relative to the bottom plate of the placement groove 4 can be done manually or electrically. When it is electrically operated, the driving method of the prior art can be referred to, such as the opening and closing driving method of an electric door.
[0069] In one implementation, a level gauge is installed inside the placement tank 4. This configuration works in conjunction with the second sealing plate 8. When an emetic is added, the level gauge reads the appropriate level, maximizing the extraction efficiency of hirudin. This prevents excessive emetic addition from causing excessive vomiting by the leeches, which would negatively impact their survival, and also avoids insufficient emetic addition which would fail to effectively induce vomiting, thus reducing the extraction yield of hirudin.
[0070] The above description is merely an embodiment of this application, and the scope of protection of this application is not limited to these specific embodiments, but is determined by the claims of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the technical concept and principles of this application should be included within the scope of protection of this application.
