Description

Technical Field

[0001] The present invention relates to the technical field of heparin sodium extraction, in particular to a heparin sodium extraction device. Background Art

[0002] Heparin sodium, as a natural anticoagulant, is the world's most effective and clinically used anticoagulant drug. It has excellent activity in anticoagulation, promoting the release of lipase and the complement cytolytic system. Crude heparin sodium is an important raw material for the manufacture of heparin sodium drugs. It is extracted from the small intestinal mucosa of healthy pigs. Because it contains a large amount of impurities such as impurities such as proteins, nucleic acids, and microorganisms, it needs to undergo physical and chemical extraction and separation processes to obtain heparin with intact natural structural groups, thereby producing crude heparin sodium.

[0003] For example, Chinese patent publication number CN107629147B discloses a sodium heparin extraction device comprising a ring blade holder, a ring scraper, an intestinal tube, an intestinal head, a pressurized tank, and an end cap. The ring blade holder is fitted with an inflatable ring scraper. The intestinal tube is mounted on one end of the ring blade holder and the intestinal head is mounted on the other end. The intestinal tube is fitted with a pressurized tank connected to the inner cavity of the ring scraper. The intestinal head is provided with a plurality of water spray channels connected to a water supply pipe.

[0004] However, the above solution has the following shortcomings: in the above patent, one end of the pig small intestine is put on the intestinal guide head, and the pig small intestine is pulled in the direction of the intestinal guide tube, and the scraping tendons on the annular scraper are used to scrape the inner wall of the pig small intestine to scrape off the intestinal mucosa on the inner wall. However, when a large damage appears on the surface of the pig small intestine, when the damage moves to the position of the annular scraper, as the pig small intestine is continuously pulled, the annular scraper may cause the pig small intestine to tear at the damage site, thereby making it impossible to continue scraping the intestinal mucosa of the pig small intestine. For this reason, we have introduced a sodium heparin extraction device. Summary of the Invention

When the pig's small intestine moves, the inflated first annular airbag 42 scrapes the intestinal mucosa inside the pig's small intestine. The first annular airbag 42 is connected to an airway 44, and the airway 44 is fixedly installed in the mounting post 19; One end of the air guide tube 44 away from the first annular airbag 42 is fixedly connected to the first three-way solenoid valve 26. The first three-way solenoid valve 26 can be selected with a suitable model and size when in use. An air supply mechanism is provided on one side of the support plate 8. The air supply mechanism is connected to the first three-way solenoid valve 26. The gas generated by the air supply mechanism enters the air guide tube 44, causing the first annular airbag 42 to swell and support the pig's small intestine. A clamping mechanism is movably sleeved on the outside of the mounting post 19, and one end of the small intestine is clamped by the clamping mechanism. A second annular airbag 48 is fixedly installed on the outside of the mounting post 19. The first three-way solenoid valve 26 is also connected to the second annular airbag 48 and the air guide cavity 46. The air guide cavity 46 is opened in the mounting post 19, and one end is connected to the external environment. The gas then enters the first three-way solenoid valve 26. The gas entering the first three-way solenoid valve 26 will enter the second annular airbag 48 and the air guide cavity 46 in turn. The gas will swell after entering the second annular airbag 48; A collecting groove 43 is provided at the lower end of the mounting column 19, and a collecting tube 13 is fixedly connected inside the mounting column 19. One end of the collecting tube 13 is connected to the collecting groove 43, and the other end is connected to the storage mechanism. The storage mechanism is connected to the support plate 8. The suction force generated by the storage mechanism is used to suck the scraped intestinal mucosa into the collecting tube 13, and then enters the storage mechanism through the collecting tube 13 for storage. An intestinal pulling mechanism is provided at the upper end of the base 1, and an air deflation mechanism is provided on the outside of the mounting column 19.

[0027] Example 2: On the basis of Example 1, in order to enable the pig intestine to be quickly sleeved on the outside of the mounting post 19, the toggle mechanism includes a sliding post 22, the sliding post 22 is movably connected to the connecting plate 30, a connecting spring 23 is sleeved on the outside of the sliding post 22, one end of the connecting spring 23 is fixedly connected to the sliding post 22, and the other end is fixedly connected to the connecting plate 30, the sliding post 22 is movably connected to the connecting wheel 21 near the end of the mounting post 19, and a plurality of toggle rods 33 are fixedly connected to the outside of the connecting wheel 21, and the toggle rods 33 are away from the connecting wheel 21. An elastic block is provided at one end, and the elastic block is made of an elastic material, such as rubber. A first motor 31 is fixedly connected to the outer side of the sliding column 22. The output end of the first motor 31 is fixedly connected to the connecting wheel 21. When the first motor 31 is turned on, it drives the connecting wheel 21 connected thereto to rotate clockwise. The rotation of the connecting wheel 21 drives several levers 33 to rotate. Since an elastic block is provided at one end of the lever 33, when the levers 33 rotate, the elastic block will push the pig intestine to the left, so that the pig intestine is folded on the outer side of the mounting column 19. A plurality of limiting holes 20 are provided on one side of the sliding post 22, and a clamping rod 34 is clamped in one of the limiting holes 20, and the clamping rod 34 is slidably connected to the sliding cavity 35. The sliding cavity 35 is provided in the connecting plate 30, and the clamping rod 34 extends into the external environment away from one end of the limiting hole 20. A supporting spring 36 is sleeved on the outside of the clamping rod 34, and one end of the supporting spring 36 is fixedly connected to the sliding cavity 35, and the other end is fixedly connected to the clamping rod 34. The clamping end of the clamping rod 34 is arranged in an inclined shape. During the process of intestinal bulging, the lever 33 will be pushed to move upward, and the sliding post 22 will be driven to move synchronously. Since the clamping end of the clamping rod 34 is arranged in an inclined shape, when the sliding post 22 moves upward, the clamping rod 34 will be squeezed out of the limiting hole 20. When the pig small intestine is deflated, the sliding post 22 will move downward under the elastic force of the connecting spring 23. At this time, the clamping rod 34 will be clamped in the limiting hole 20 again, so that the sliding post 22 cannot move downward. The air supply mechanism includes an air pump 15, which is fixedly connected to the support plate 8. The output end of the air pump 15 is fixedly connected to the second three-way solenoid valve 14, and the second three-way solenoid valve 14 is connected to the first three-way solenoid valve 26. The storage mechanism includes a storage box 10, which is fixedly connected to the support plate 8. A baffle 11 is fixedly connected to the inside of the storage box 10. A fan 12 is fixedly installed on the upper end of the storage box 10. The baffle 11 is set so that the intestinal mucosa entering the storage box 10 will not be attracted by the fan 12. A valve 9 is fixedly installed at the lower end of the storage box 10. By opening the valve 9, the scraped intestinal mucosa can be discharged from the storage box 10. The upper end of the storage box 10 is fixedly connected to the collection pipe 13; The clamping mechanism includes a slip ring 17, which is movably sleeved on the outside of the mounting column 19. The outside of the slip ring 17 is provided with an arc-shaped groove. The outside of the slip ring 17 is sleeved with an elastic clamping ring 16. The elastic clamping ring 16 is made of rubber. A sealing groove 47 is provided on the inside of the slip ring 17. The intestine pulling mechanism includes a connecting frame 24, the lower end of the connecting frame 24 is fixedly connected to a T-block 4, the T-block 4 slides in the T-slot 5, the T-slot 5 is opened at the upper end of the base 1, a telescopic cylinder 3 is fixedly installed in the base 1, the output end of the telescopic cylinder 3 is fixedly connected to the T-block 4, the connecting frame 24 is fixedly connected to the collecting bucket 6 on the side away from the support plate 8, two guide wheels 25 are provided on the inner side of the connecting frame 24, and a number of protrusions are provided on the outer side of the guide wheel 25. The friction between the guide wheel 25 and the pig small intestine is increased by the setting of the protrusions. The lower guide wheel 25 is movably connected to the connecting frame 24, and the upper guide wheel 25 is movably connected to the lower end of the mounting seat 27. The upper end of the mounting seat 27 is fixedly connected to a T-rod 29, which is movably connected to the connecting frame 24. A push spring 28 is sleeved on the outer side of the T-rod 29. One end of the push spring 28 is fixedly connected to the mounting seat 27, and the other end is fixedly connected to the inner side of the connecting frame 24.

[0028] The deflation mechanism includes a slide plate 38, which is slidably connected to a connecting cavity 41. The connecting cavity 41 is opened in the mounting column 19. The upper end of the slide plate 38 is fixedly connected to an extrusion block 39. The upper end of the extrusion block 39 is circular and extends into the external environment. The lower end of the slide plate 38 is fixedly connected to two return springs 37. The elastic force of the two return springs 37 is greater than the rebound force of the pressing end of the second press switch 18, to prevent the pig small intestine from fully inflating and the excess gas from pushing the slide plate 38 to move. The lower end of the return spring 37 is fixedly connected to the connecting cavity 41. The first press switch 7 is fixedly connected in the connecting cavity 41. An exhaust hole 40 is opened on the outside of the mounting column 19. The exhaust hole 40 is connected to the connecting cavity 41, and the connecting cavity 41 is also connected to the air guide tube 44.

[0029] A second push switch 18 is fixedly installed on the outside of the mounting column 19, and a pressure plate 45 is fixedly connected to the output end of the second push switch 18. A speaker 2 is fixedly installed on the base 1, and a magnetic ring 32 is fixedly installed on the side of the support plate 8 close to the mounting column 19. The slip ring 17 is adsorbed by the setting of the magnetic ring 32.

[0030] Working principle: when in use, one end of the soaked pig intestine is sleeved on the outside of the slip ring 17, and after the sleeve is completed, the elastic clamping ring 16 is sleeved on the outside of the slip ring 17. At this time, under the elastic force of the elastic clamping ring 16, one end of the pig intestine is fixed on the outside of the slip ring 17, and the slip ring 17 with the pig intestine sleeved is sleeved on the outside of the mounting post 19 and pushed to the left. When the slip ring 17 contacts the magnetic ring 32, the slip ring 17 is attracted by the magnetic ring 32, and the two clamping rods 34 are pulled outward to make its clamping end disengage from the limiting hole 20. At this time, under the elastic force of the connecting spring 23, the sliding post 22 moves downward and drives the connecting wheel 21 to move synchronously. Under the limit of the connecting plate 30, the sliding post 22 moves downward for an end distance and then stops. At this time, the lever 33 contacts the pig intestine. When the first motor 31 is turned on, the connecting wheel 21 connected thereto rotates clockwise, and the connecting wheel 21 rotates and drives several levers 33 to rotate. Since an elastic block is provided at one end of the lever 33, when several levers 33 are rotated, the elastic block will push the pig intestine to the left, so that the pig intestine is folded on the outside of the mounting post 19. When most of the pig intestine is installed on the outside of the mounting post 19, the first motor 31 is turned off, the telescopic cylinder 3 is turned on, and the T-shaped block 4 connected thereto moves left along the T-shaped slot 5. At this time, the connecting frame 24 follows and moves. When the connecting frame 24 moves to the leftmost position, the telescopic cylinder 3 is turned off, and the T-shaped rod 29 is pulled upward to drive the guide wheel 25 connected thereto to move, so that the right end of the pig intestine is placed between the upper and lower guide wheels 25, and the lifting of the T-shaped rod 29 is released. At this time, under the elastic force of the push spring 28, the right end of the pig intestine is clamped between the two guide wheels 25; Turn on the air pump 15 to generate gas that enters the second three-way solenoid valve 14, and then the gas enters the first three-way solenoid valve 26. The gas that enters the first three-way solenoid valve 26 will enter the second annular airbag 48 and the air guide cavity 46 in sequence. After entering the second annular airbag 48, the gas will swell and enter the sealing groove 47. The gas that enters the air guide cavity 46 will enter the pig's small intestine and make the pig's small intestine swell. When the pig's small intestine is not damaged, the gas after the pig's small intestine is fully inflated will push the pressure plate 45 to move downward. At this time, the pressure plate 4 5 will press the second push switch 18, the air pump 15 will stop working, and the second three-way solenoid valve 14 will switch, so that the second three-way solenoid valve 14 is no longer connected to the air pump 15. At this time, the gas will re-enter the second three-way solenoid valve 14 through the first three-way solenoid valve 26 and be discharged. On the contrary, when the pig small intestine is severely damaged, the gas generated by the air pump 15 will not cause the pig small intestine to bulge. When the second push switch 18 is not pressed for a set period of time, the speaker 2 will sound to remind the operator, and the air pump 15 will be turned off; When the pig's small intestine is bulging, the lever 33 will be pushed to move upward, and the sliding post 22 will be driven to move synchronously. Since the clamping end of the clamping rod 34 is arranged in an inclined shape, when the sliding post 22 moves upward, the clamping rod 34 will be squeezed out of the limiting hole 20. When the pig's small intestine is exhausted, the sliding post 22 will move downward under the elastic force of the connecting spring 23. At this time, the clamping rod 34 will be clamped in the limiting hole 20 again, making the sliding post 22 unable to move downward. When it is detected that the pig's small intestine is not damaged and exhausted, the second three-way solenoid valve 14 is restarted to connect the air pump 15 with the first three-way solenoid valve 26. At the same time, the first three-way solenoid valve 26 is started to connect the air guide pipe 44 with the second three-way solenoid valve 14. At this time, the gas generated by the air pump 15 will enter the air guide pipe 44 instead of entering the second annular airbag 48. The gas entering the air guide pipe 44 will cause the first annular airbag 42 to swell and support the pig's small intestine. At this time, the second motor 49 is turned on to drive the guide wheel 25 connected thereto to rotate clockwise. The guide wheel 25 pulls the pig's small intestine during the rotation. At this time, the pig's small intestine moving to the right will be scraped off the intestinal mucosa by the first annular airbag 42. At the same time, the fan 12 will generate suction after starting, so that the scraped intestinal mucosa is sucked into the collection pipe 13 through the collecting tank 43, and finally enters the storage box 10 for storage; As the guide wheel 25 continues to rotate, the left end of the pig intestine will be driven to move. At this time, the slip ring 17 will move to the right along the mounting column 19. When the slip ring 17 contacts the extrusion block 39, as the slip ring 17 continues to move, the extrusion block 39 will be squeezed downward and drive the slide plate 38 to move synchronously. At this time, the slide plate 38 will press the first push switch 7 to stop the second motor 49 from rotating. At the same time, the slide plate 38 will cancel the blockage of the exhaust hole 40, and the gas in the first annular airbag 42 will be discharged through the exhaust hole 40, so that the first annular airbag 42 is in a contracted state again. The slip ring 17 can be removed and a new slip ring 17 holding the pig intestine can be installed.
