Description

TECHNICAL FIELD

[0002] As a natural anticoagulant, heparin sodium is the most effective and largest clinical dosage anticoagulant in the world, and has good activity in anticoagulation, promotion of lipoprotein enzyme release and complement cell lysis system. Heparin sodium crude product is an important raw material for manufacturing heparin sodium drugs, and is derived from the small intestinal mucosa of healthy pigs. Since it contains a large amount of impurity proteins, impurity nucleic acids, microorganisms and other impurities, it needs to undergo physical and chemical extraction and separation processes to obtain heparin with complete natural structure groups, so as to obtain heparin sodium crude product.

[0003] For example, a heparin sodium extraction device is disclosed in Chinese Patent No. CN107629147B, which comprises a ring cutter seat, a ring scraper, a guide intestine tube, a guide intestine head, a pressurizing tank and an end cover.

[0034] Embodiment 2:

[0035] On the basis of embodiment 1, in order to enable the pig small intestine to be quickly sleeved on the outer side of the mounting column 19, the pushing mechanism comprises a sliding connection column 22 which is movably connected in the connecting plate 30. The sliding connection column 22 is sleeved with a connecting spring 23 on the outer side.

The clamping end of the clamping rod 34 is obliquely arranged. During the process of the pig small intestine being inflated, the push rod 33 will be pushed to move upward. At this time, the sliding connection column 22 will be driven to move synchronously. Since the clamping end of the clamping rod 34 is obliquely arranged, the clamping rod 34 will be extruded to be separated from the limiting hole 20 when the sliding connection column 22 moves upward. After the pig small intestine is deflated, the sliding connection column 22 will move downward under the elastic force of the connecting spring 23. At this time, the clamping rod 34 will be reconnected in the limiting hole 20, so that the sliding connection column 22 cannot move downward.

[0037] The air supply mechanism comprises an air pump 15 fixedly connected with the support plate 8, and the output end of the air pump 15 is fixedly connected with the second three-way electromagnetic valve 14, which is connected with the first three-way electromagnetic valve 26; the storage mechanism comprises a storage tank 10 fixedly connected with the support plate 8, and the inner side of the storage tank 10 is fixedly connected with a baffle 11; the upper end of the storage tank 10 is fixedly provided with a fan 12; the baffle 11 is arranged to prevent the intestinal mucosa entering the storage tank 10 from being sucked by the fan 12; the lower end of the storage tank 10 is fixedly provided with a valve 9, which can be opened to discharge the scraped intestinal mucosa from the storage tank 10; and the upper end of the storage tank 10 is fixedly connected with a collecting pipe 13.

[0040] The air releasing mechanism comprises a sliding plate 38 slidably connected in a connecting cavity 41 provided in the mounting column 19, an extrusion block 39 fixedly connected with the upper end of the sliding plate 38, the upper end of the extrusion block 39 being circularly arranged and extending into the external environment, two reset springs 37 fixedly connected with the lower end of the sliding plate 38, the elastic force of the two reset springs 37 being greater than the rebound force of the pressing end of the second pressing switch 18, so that the excess gas can first push the sliding plate 38 to move after the pig small intestine is fully inflated and bulged; the lower end of the reset spring 37 is fixedly connected with the connecting cavity 41, the connecting cavity 41 is fixedly connected with the first pressing switch 7, the mounting column 19 is provided with an air exhaust hole 40 in communication with the connecting cavity 41, and the connecting cavity 41 is also in communication with a gas guide pipe 44.

[0041] The second press switch 18 is fixedly installed outside the mounting column 19, the output end of the second press switch 18 is fixedly connected with the pressing plate 45, the loudspeaker 2 is fixedly installed in the base 1, the magnetic ring 32 is fixedly installed on the side of the supporting plate 8 close to the mounting column 19, and the sliding ring 17 is adsorbed through the magnetic ring 32.

[0042] When in use, the immersed and bleached pig small intestine is sleeved on the outside of the sliding ring 17, the elastic clamping ring 16 is sleeved on the outside of the sliding ring 17 after the sleeving is completed, at this time, the one end of the pig small intestine is fixed on the outside of the sliding ring 17 under the elastic force of the elastic clamping ring 16, the sliding ring 17 sleeved with the pig small intestine is sleeved on the outside of the mounting column 19 and is pushed to the left, when the sliding ring 17 contacts the magnetic ring 32, at this time, the sliding ring 17 is adsorbed by the magnetic ring 32, the two clamping rods 34 are pulled outwards, so that the clamping ends are separated from the limiting holes 20, at this time, under the elastic force of the connecting spring 23, the sliding column 22 moves downwards and drives the connecting wheel 21 to move synchronously, under the limiting of the connecting plate 30, the sliding column 22 stops after moving downwards by a distance, at this time, the push rod 33 contacts the pig small intestine;

[0043] The first motor 31 is opened, the connecting wheel 21 connected with the first motor 31 is driven to rotate clockwise, the connecting wheel 21 drives the plurality of push rods 33 to rotate, because the elastic block is arranged at one end of the push rod 33, the elastic block drives the pig small intestine to be pushed to the left under the rotation of the plurality of push rods 33, so that the pig small intestine is folded on the outside of the mounting column 19, when most of the pig small intestine is installed on the outside of the mounting column 19, at this time, the first motor 31 is closed, the telescopic cylinder 3 is opened, the T-shaped block 4 connected with the telescopic cylinder 3 is driven to move to the left along the T-shaped groove 5, at this time, the connecting frame 24 moves, when the connecting frame 24 moves to the leftmost position, at this time, the telescopic cylinder 3 is closed, the T-shaped rod 29 is pulled upwards, the guide wheel 25 connected with the T-shaped rod 29 is driven to move, the right end of the pig small intestine is placed between the upper and lower guide wheels 25, the T-shaped rod 29 is loosened, at this time, under the elastic force of the pushing spring 28, the right end of the pig small intestine is clamped between the two guide wheels 25.

[0044] The gas pump 15 is opened to generate gas into the second three-way electromagnetic valve 14, and then into the first three-way electromagnetic valve 26. The gas entering the first three-way electromagnetic valve 26 will enter the second annular air bag 48 and the gas guide cavity 46 in turn. After entering the second annular air bag 48, the gas will swell and enter the sealing groove 47. The gas entering the gas guide cavity 46 will enter the pig small intestine and make the pig small intestine swell. When the pig small intestine is not damaged, the gas after inflating the pig small intestine will push the pressing plate 45 to move downward. At this time, the pressing plate 45 will press the second pressing switch 18, and the gas pump 15 will stop working. At the same time, the second three-way electromagnetic valve 14 will switch so that the second three-way electromagnetic valve 14 is no longer connected with the gas pump 15. At this time, the gas will re-enter the second three-way electromagnetic valve 14 through the first three-way electromagnetic valve 26 and be discharged. Conversely, when the pig small intestine is damaged, the gas generated by the gas pump 15 will not make the pig small intestine swell. When the second pressing switch 18 is not pressed after reaching the set time, the loudspeaker 2 will ring to remind the operator, and the gas pump 15 will be closed;

[0045] And in the process of swelling of the pig small intestine, the push rod 33 will be pushed to move upward. At this time, the sliding column 22 will be driven to move synchronously. Since the clamping end of the clamping rod 34 is arranged in an inclined manner, when the sliding column 22 moves upward, the clamping rod 34 will be extruded to disengage from the limiting hole 20. After the pig small intestine is exhausted, under the elastic force of the connecting spring 23, the sliding column 22 will move downward. At this time, the clamping rod 34 will re-clamp in the limiting hole 20, so that the sliding column 22 cannot move downward,

[0046] When it is detected that the pig small intestine is not damaged and exhausted, the second three-way electromagnetic valve 14 is restarted to make the gas pump 15 connected with the first three-way electromagnetic valve 26. At the same time, the first three-way electromagnetic valve 26 is started to make the gas guide pipe 44 connected with the second three-way electromagnetic valve 14. At this time, the gas generated by the gas pump 15 will enter the gas guide pipe 44, but not enter the second annular air bag 48. The gas entering the gas guide pipe 44 will make the first annular air bag 42 swell and support the pig small intestine. At this time, the second motor 49 is opened to drive the guide wheel 25 connected therewith to rotate clockwise. The guide wheel 25 will pull the pig small intestine during rotation. At this time, the pig small intestine moving to the right will be scraped of the intestinal mucosa by the first annular air bag 42. At the same time, the fan 12 will generate suction after starting to make the scraped intestinal mucosa sucked into the collecting pipe 13 through the collecting groove 43 and finally enter the storage box 10 for storage.

[0047] With the continuous rotation of the guide wheel 25, the left end of the pig small intestine is moved, at this time the sliding ring 17 moves right along the mounting column 19, when the sliding ring 17 contacts the extrusion block 39, with the continuous movement of the sliding ring 17, the extrusion block 39 is extruded downward and the sliding plate 38 is synchronously moved, at this time the sliding plate 38 presses the first pressing switch 7, so that the second motor 49 stops rotating, at the same time the sliding plate 38 cancels the blockage of the exhaust hole 40, the gas in the first annular air bag 42 is discharged through the exhaust hole 40, so that the first annular air bag 42 is in the contracted state again, the sliding ring 17 is removed and a new sliding ring 17 clamping the pig small intestine is installed.

[0048] The above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be noted that for those skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
