Description

Technical Field

[0001] The invention relates to the technical field of hirudin extraction, in particular to an induction device for hirudin extraction. Background Art

[0002] Hirudin is the most active and most studied ingredient among the many active ingredients extracted from leeches and their salivary glands. It is a small molecule protein composed of 65-66 amino acids. Leeches are rich in hirudin, which has a strong inhibitory effect on thrombin and is the strongest natural specific inhibitor of thrombin discovered so far. In the process of extracting hirudin, an induction device is required to enable leeches to excrete hirudin.

[0003] However, there are some problems in the extraction process of existing hirudin. According to the traditional hirudin extraction method, a large number of leeches will be consumed, and the leeches can only be extracted once, and it is impossible to extract hirudin multiple times in a cycle. At the same time, with the continuous development of modern technology, a new method for extracting hirudin has been proposed, which is a method for extracting it multiple times in vivo. In this technology, induction liquid, emetic liquid and other technologies are used. In the existing technology, a large number of leeches that have been hungry for more than one week are often put into the induction liquid at one time, so that the leeches can absorb the leech at one time. After the leeches have eaten a large amount of inducing liquid, they are in a "false" full state. In this state, the leeches will temporarily be unable to absorb more inducing liquid, which may affect the subsequent excretion efficiency of hirudin. Moreover, after the leeches have excreted hirudin, the existing technology is not convenient for packaging the hirudin, which will affect the subsequent extraction and refining of the hirudin. Considering that some scientific researchers may have aversion to leeches, the existing technology has not yet considered how to place the leeches in the extraction device and how to take the leeches out after the hirudin extraction is completed.

A connecting hole is opened at the bottom of the limiting column 22. Four discharge holes are opened at the outer edge of the limiting column 22 near the top and the bottom. Several discharge holes located below are located in adjacent through holes. A filter screen 23 is fixedly connected to the connection hole near the bottom. Two first limiting plates 37 are fixedly connected to the outer edge of the limiting column 22 near the top. The top of the sealing frame 9 near the left and right sides are plugged with limiting L-shaped plates 19; A vertical hole is provided at the center of the top of the sealing frame 9, and a conical tube 24 is fixedly connected in the vertical hole. Two second limiting plates 38 are fixedly connected to the inner cavity of the conical tube 24 near the bottom. A sealing disk 28 is provided on the top of the two second limiting plates 38. The outer edge of the sealing disk 28 and the side wall of the inner cavity of the conical tube 24 are arranged to fit each other near the bottom. A vertical rod 27 is fixedly connected to the center of the top of the sealing disk 28, and an elastic plate 26 is fixedly connected to the top of the vertical rod 27. The front and rear sides of the elastic plate 26 are fixedly connected to a connecting L-shaped plate 25. The side of the connecting L-shaped plate 25 away from the elastic plate 26 is fixedly connected to the top of the sealing frame 9, and the connecting circular frame 7 is inserted at the center of the bottom. A connecting rod 36 is connected, a cross rod 33 is fixedly connected to the bottom end of the connecting rod 36, four arc-shaped plates 34 are fixedly connected to the outer edge of the cross rod 33, a plurality of collecting cylinders 30 are arranged at the bottom of the connecting circular frame 7, the top of each collecting cylinder 30 is fixedly connected to a first sealing ring 31, the top of the first sealing ring 31 fits with the bottom of the connecting circular frame 7, a fixing plate 32 is fixedly connected between two adjacent collecting cylinders 30, two first threaded holes are provided on the outer edge of the collecting cylinder 30 close to the arc-shaped plate 34, two second threaded holes are provided on the arc-shaped plate 34, and bolts 35 are threadedly connected in the adjacent first threaded holes and the second threaded holes; The electric telescopic rod 8 controls the connecting circular frame 7 to move up and down, and the connecting circular frame 7 is slowly moved downward. The inducing liquid inside the connecting tube 1 enters into the connecting circular frame 7 through the hole inside the limiting column 22, and the inducing liquid is discharged into the connecting circular frame 7 in small amounts and multiple times, so as to perform hunger marketing on the leeches, so that the leeches can absorb more inducing liquid. When the leeches are full, the connecting circular frame 7 moves upward, and there is a small amount of inducing liquid inside the connecting circular frame 7. At the same time, the vertical rod 27 is moved upward, and the vertical rod 27 drives the sealing disk 28 to move upward, and the emetic liquid inside the conical tube 24 enters into the connecting circular frame 7, so that the saliva in the body, that is, the crude natural hirudin liquid, is spit out. Then, the collecting tube 30 is rotated to the bottom of the limiting column 22, and the sealing frame 9 is moved upward. The hirudin will flow into the collecting tube 30 through the hole below the surface of the limiting column 22, and then the collecting tube 30 is taken out to extract and refine the hirudin.

[0018] Working principle: When the device starts working, the researcher sits on the seat 4, takes out the paper from the collecting box 6, observes and records the working status of the leech, starts the pump 15 first, and the pump 15 absorbs the inducing liquid through the connecting tube 16. The inducing liquid enters the connecting tube 1 through the fixed tube 17, and then turns off the pump 15, starts the two electric telescopic rods 8, and the two electric telescopic rods 8 drive the horizontal plate 21 and the vertical plate 20 to move downward, and the vertical plate 20 drives the connecting circular frame 7 and the sealing frame 9 to move downward, and the bottom of the connecting circular frame 7 gradually contacts the inducing liquid inside the connecting tube 1, and the inducing liquid enters the limiting column 22. The inducing liquid inside the limiting column 22 will gradually move upward until the inducing liquid is discharged through the holes above the surface of the limiting column 22. The inducing liquid will slowly enter the inside of the connecting circular frame 7 in small amounts and multiple times, while the holes below the surface of the limiting column 22 are blocked by the through holes and the inducing liquid cannot be discharged. The leeches on the movable circular frame 18 inside the connecting circular frame 7 will suck the inducing liquid, thereby performing hunger marketing on the leeches. By discharging the inducing liquid in small amounts and multiple times, the leeches can suck more inducing liquid. After the leeches are full, the electric telescopic rod 8 drives the connecting circular frame 7 and the sealing frame 9 to move upward until the collecting tube 30 is exposed. When the connecting circular frame 7 is immersed in the inducing liquid, the collecting tube 30 is kept inside by the first sealing ring 31 on the top to prevent or prevent a small amount of infiltration of the inducing liquid. After the collecting tube 30 moves to the top of the connecting tube 1, the researchers rotate the collecting tube 30, and the collecting tube 30 drives the fixing plate 32 and the bolts 35. The arc plate 34, the cross rod 33 and the connecting rod 36 rotate to rotate the collecting tube 30 to the bottom of the adjacent limiting column 22. Then the researchers move the vertical rod 27 upwards. The vertical rod 27 drives the elastic plate 26 to stretch. The vertical rod 27 drives the sealing disk 28 to move upwards. The sealing disk 28 gradually moves away from the inner wall of the conical tube 24. The emetic liquid inside the conical tube 24 will be discharged into the connecting circular frame 7, so that the leech spits out the saliva in the body, that is, the crude natural hirudin liquid. Then the researchers drive the sealing frame 9 to move upwards through the limiting L-shaped plate 19. The sealing frame 9 drives the limiting column 22 to move upwards. The hole below the surface of the limiting column 22 will enter the inside of the connecting circular frame 7. The researchers pause and stop moving the sealing frame 9. The hirudin will flow out through the holes below the surface of the limiting column 22, and gradually flow into the adjacent collecting tube 30. After the collection of the hirudin is completed, the researcher rotates the bolt 35, removes the bolt 35 from the surface of the adjacent collecting tube 30, thereby taking out the collecting tube 30, and subsequently extracting and refining the hirudin inside the collecting tube 30. After the work is completed, when it is necessary to clean the connecting circular frame 7 and the inside of the connecting tube 1, the researcher pinches the connecting circular frame 7 and the sealing frame 9 with his hands, and rotates the connecting circular frame 7 and the sealing frame 9 so that the sealing frame 9 rotates downward and the connecting circular frame 7 rotates upward. The researcher can then loosen the connecting circular frame 7, hold the sealing frame 9 with his hands, and the movable circular frame 18 will move toward the sealing frame 9 by gravity.When the movable circular frame 18 moves toward the sealing frame 9, the leeches will be driven to move, and the leeches will fall into the sealing frame 9. The first limit plate 37 supports the movable circular frame 18 to prevent the movable circular frame 18 from pressing the leeches, so that the sealing frame 9 and the leeches can be taken out. Since the sealing frame 9 is not transparent, the psychological pressure of researchers who are afraid of leeches will be reduced.
