Description

Technical Field

[0001] The invention relates to the technical field of gastric juice extraction equipment, in particular to an electric extraction equipment for sheep rumen fluid. Background Art

[0002] For example, the Chinese patent with announcement number CN213821504U discloses a rumen fluid collection device for sheep, which relates to the field of animal science experimental technology, including: a manual negative pressure device, a collection bottle and a gastric fluid outlet tube; the air intake of the manual negative pressure device and one end of the gastric fluid outlet tube are both connected to the collection bottle, and the other end of the gastric fluid outlet tube is used to extend into the sheep's rumen through the sheep's mouth.

[0003] However, the above solution has the following shortcomings: in the above patent, a gastric juice outlet tube is inserted into the sheep's stomach, and the gastric juice in the sheep's rumen is pumped into a collection bottle through a manual negative pressure device. However, during use, since the composition of rumen fluid usually includes food residues, microorganisms, digestive fluid, etc., if the sheep has eaten or is digesting food, the rumen fluid may present different layers. At this time, the liquid pumped into the outlet tube may be a mixture of gastric juice and food residues, causing the outlet tube to be blocked, resulting in the rumen fluid being unable to be pumped into the collection bottle. For this reason, we have introduced an electric extraction device for sheep rumen fluid. Summary of the Invention

[0004] The object of the present invention is to provide an electric extraction device for sheep rumen fluid to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A sheep rumen fluid electric extraction device includes a collection bottle and a sample collection tube. The upper end of the collection bottle is movably mounted with a bottle cap via a buckle. A first connecting tube and a second connecting tube are fixedly mounted in the bottle cap, respectively. The lower ends of the first connecting tube and the second connecting tube extend into the collection bottle. The lower end of the second connecting tube is fixedly connected to a first one-way valve. The upper ends of the first connecting tube and the second connecting tube extend into the external environment and are fixedly connected to a three-way valve.

[0007] An airway is fixedly connected between the two three-way valves, and a liquid extraction hose is fixedly connected to the upper ends of the two three-way valves. The end of the left liquid extraction hose away from the three-way valve is connected to the liquid extraction filter mechanism, and the end of the right liquid extraction hose away from the three-way valve is connected to the extraction mechanism. The extraction mechanism generates suction, so that gastric fluid passes through the liquid extraction filter mechanism and enters the left liquid extraction hose, and finally enters the collection bottle to be collected.

[0008] A connecting mechanism is provided in the lower end of the collecting bottle, and a screw cap is screwed on the upper end of the sample collecting tube. The sample collecting tube is screwed into the connecting mechanism by opening the screw cap, so that the collecting bottle is connected to the sample collecting tube through the connecting mechanism, and the gastric fluid in the collecting bottle enters the sample collecting tube. The liquid extraction and filtration mechanism includes a circular box, and a first cross-shaped slide groove is provided on the outside of the circular box.

[0009] Preferably, a movable tube is movably connected in the first cross-shaped slide groove, two annular connecting plates are fixedly connected to the inner side of the circular box, and slide grooves are provided on the opposite surfaces of the two annular connecting plates. A retaining ring is slidably connected between the two slide grooves, and the movable tube is fixedly connected in the retaining ring. The upper end of the movable tube extends between the two annular connecting plates.

[0010] Preferably, sliders are fixedly connected on both sides of the movable tube, and the sliders are slid into the first cross-shaped slide groove. The lower end of the movable tube is fixedly connected to a counterweight box, and the lower end of the counterweight box is fixedly connected to a filter plate. One end of the liquid extraction hose on the left side passes through the circular box and extends into the inner side of an annular connecting plate. Floating blocks are fixedly connected at both ends of the circular box.

[0011] Preferably, the extraction mechanism includes a connecting box, one end of the liquid extraction hose on the right side is fixedly connected to the connecting box, a sealing slide is slidably connected in the connecting box, the connecting box is movably connected to a T-shaped push rod at one end away from the liquid extraction hose, one end of the T-shaped push rod is fixedly connected to the sealing slide, a return spring is sleeved on the outside of the T-shaped push rod, one end of the return spring is fixedly connected to the sealing slide, and the other end is fixedly connected to the connecting box, a one-way valve is fixedly connected in one end of the connecting box, and one end of the one-way valve is fixedly connected to the valve.

[0012] Preferably, the connecting mechanism includes a connecting cavity, which is opened at the lower end of the collecting bottle, and is provided with an internal thread in the connecting cavity.

A connecting spring is sleeved on the outside of the liquid catheter, and one end of the connecting spring is fixedly connected to the liquid catheter, and the other end is fixedly connected to the connecting cavity.

[0013] Compared with the prior art, the beneficial effect of the present invention is: by sending the liquid extraction and filtering mechanism together with the liquid extraction hose into the sheep rumen, the liquid extraction and filtering mechanism will float on the upper side of the gastric fluid, and the gastric fluid will be drawn into the liquid extraction and filtering mechanism through the extraction mechanism. The gastric fluid entering the liquid extraction and filtering mechanism will be filtered, and the gastric fluid will eventually pass through the liquid extraction hose to the collection bottle.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-8 , the present invention provides a technical solution:

[0025] Example 1:

[0026] A sheep rumen fluid electric extraction device comprises a collecting bottle 1 and a sample collecting tube 6, wherein a bottle cap 29 is movably mounted on the upper end of the collecting bottle 1 through a buckle, and the bottle cap 29 can be removed from the upper end of the collecting bottle 1 by opening the buckle, so that the gastric fluid extracted from the collecting bottle 1 can be poured out, and the collecting bottle 1 can be cleaned. When the operation is completed, the bottle cap 29 can be reinstalled on the upper end of the collecting bottle 1 through the buckle, and a first connecting tube 2 and a second connecting tube 3 are fixedly mounted in the bottle cap 29 respectively, wherein the length of the first connecting tube 2 is greater than the length of the second connecting tube 3, and the lower ends of the first connecting tube 2 and the second connecting tube 3 both extend into the collecting bottle 1, and the lower end of the second connecting tube 3 is fixedly connected to a first one-way valve 31, and through the setting of the first one-way valve 31, the gas in the collecting bottle 1 can enter the second connecting tube 3, and the air in the second connecting tube 3 will not enter the collecting bottle 1;

[0027] The upper ends of the first connecting pipe 2 and the second connecting pipe 3 are both extended into the external environment and are fixedly connected to the three-way valve 8. When the three-way valve 8 is actually used, a valve with a switch adjustment function should be selected. The two connection ports in the three-way valve 8 can be connected by adjusting the switch. An air guide pipe 9 is fixedly connected between the two three-way valves 8. The upper ends of the two three-way valves 8 are respectively fixedly connected to a liquid extraction hose 16. The left liquid extraction hose 16 is connected to the liquid extraction filter mechanism at one end away from the three-way valve 8, and the right liquid extraction hose 16 is connected to the liquid extraction filter mechanism at one end away from the three-way valve 8. The ends are connected to the extraction mechanism. When the upper and lower ends of the three-way valve 8 on the left are opened, the first connecting pipe 2 is connected to the liquid extraction hose 16. When the upper and lower ends of the three-way valve 8 on the right are opened, the second connecting pipe 3 is connected to the liquid extraction hose 16 on the right. When the opposite ends and the upper end of the two three-way valves 8 are opened, the liquid extraction hoses 16 on the left and right sides are connected to the airway 9. The suction force generated by the extraction mechanism allows the gastric fluid to pass through the liquid extraction and filtration mechanism into the liquid extraction hose 16 on the left, and the gastric fluid is finally collected in the collection bottle 1;

[0028] A connecting mechanism is provided in the lower end of the collecting bottle 1, and a screw cap 5 is screwed on the upper end of the sample collecting tube 6. When a small dose of gastric fluid is needed for testing, the screw cap 5 is opened and the sample collecting tube 6 is screwed into the connecting mechanism, so that the collecting bottle 1 is connected to the sample collecting tube 6 through the connecting mechanism, and the gastric fluid in the collecting bottle 1 enters the sample collecting tube 6. When the sample collecting tube 6 completes the collection of the gastric fluid, the sample collecting tube 6 storing the gastric fluid is unscrewed, and the screw cap 5 is re-screwed on the upper end of the sample collecting tube 6.

[0029] Example 2:

[0030] On the basis of Example 1, in order to enable the liquid extraction and filtering mechanism to be arranged on the upper side of the gastric fluid, the liquid extraction and filtering mechanism includes a circular box 22, a first cross-shaped chute 21 is provided on the outer side of the circular box 22, a movable tube 17 is movably connected in the first cross-shaped chute 21, two annular connecting plates 25 are fixedly connected to the inner side of the circular box 22, and the opposite surfaces of the two annular connecting plates 25 are provided with chutes 30. A retaining ring 24 is slidably connected between the two chutes 30, and the movable tube 17 is fixedly connected in the retaining ring 24. The upper end of the movable tube 17 extends between the two annular connecting plates 25, and the retaining ring 24 blocks the space between the two annular connecting plates 25, so that the gastric fluid in the movable tube 17 will not flow out when it enters the inner sides of the two annular connecting plates 25;

[0031] The movable tube 17 is fixedly connected to a slider 20 on both sides, and the slider 20 is slidably connected to the first cross-shaped slide 21. When the movable tube 17 rotates, the slider 20 will move along the first cross-shaped slide 21, and the lower end of the movable tube 17 is fixedly connected to the counterweight box 19. The lower end of the counterweight box 19 is fixedly connected to the filter plate 18. One end of the left liquid extraction hose 16 passes through the circular box 22 and extends into the inner side of an annular connecting plate 25. Both ends of the circular box 22 are fixedly connected to floating blocks 23. The material of the floating blocks 23 can be corrosion-resistant and lightweight materials, such as polytetrafluoroethylene. Under the buoyancy of the two floating blocks 23, the circular box 22 will float on the surface of the gastric fluid. At the same time, under the gravity of the counterweight box 19, the counterweight box 19 will pull the movable tube 17 to rotate, so that the counterweight box 19 is always located in the gastric fluid, and when the movable tube 17 rotates, the retaining ring 24 will move along the slide 30;

[0032] The extraction mechanism includes a connecting box 14, one end of the right side liquid extraction hose 16 is fixedly connected to the connecting box 14, a sealing slide 11 is slidably connected to the connecting box 14, and the connecting box 14 is movably connected to a T-type push rod 13 at one end away from the liquid extraction hose 16. One end of the T-type push rod 13 is fixedly connected to the sealing slide 11, and a return spring 12 is sleeved on the outside of the T-type push rod 13. One end of the return spring 12 is fixedly connected to the sealing slide 11, and the other end is fixedly connected to the connecting box 14. A second one-way valve 10 is fixedly connected to one end of the connecting box 14, and one end of the second one-way valve 10 is fixedly connected to the valve 15. By pulling the T-type push rod 13 to move, the sealing slide 11 is driven to move. When the sealing slide 11 moves, suction is generated in the connecting box 14, and the return spring 12 is compressed. At this time, the return spring 12 is located in the rumen of the sheep. When the sealing slide 11 moves, the gastric juice is sucked into the counterweight box 19. The gastric juice entering the counterweight box 19 is filtered by the filter plate 18, and then enters the annular connecting plate 25 through the movable tube 17, and finally enters the collecting bottle 1 through the liquid extraction hose 16 and the first connecting tube 2 for storage. Since the first connecting tube 2 and the second connecting tube 3 are arranged at different heights, when the gastric juice enters the collecting bottle 1 through the first connecting tube 2, the gastric juice will not enter the second connecting tube 3 again. At the same time, under the setting of the first one-way valve 31, when the gastric juice is not extracted into the collecting bottle 1 once, when the operator continuously pulls the T-shaped push rod 13, the gas in the connecting box 14 will be discharged to the outside through the second one-way valve 10 and the valve 15, thereby realizing continuous extraction of gastric juice;

[0033] The connecting mechanism includes a connecting cavity 27, which is opened at the lower end of the collecting bottle 1. An internal thread 26 is opened in the connecting cavity 27. A liquid catheter 4 is slidably connected in the connecting cavity 27. Liquid inlet grooves 7 are opened on both sides of the liquid catheter 4. The liquid inlet grooves 7 are opened on the left and right sides of the liquid catheter 4. The liquid catheter 4 is connected to the inner side of the collecting bottle 1 through the liquid inlet grooves 7. The gastric fluid in the collecting bottle 1 will enter the sample collection tube 6 through the liquid catheter 4 for storage;

[0034] A connecting spring 28 is sleeved on the outside of the liquid catheter 4. One end of the connecting spring 28 is fixedly connected to the liquid catheter 4, and the other end is fixedly connected to the connecting cavity 27. The upper end of the sample collection tube 6 is screwed to the internal thread 26 in the connecting cavity 27. At this time, as the sample collection tube 6 continues to move upward, the liquid catheter moves upward, and the liquid catheter 4 is connected to the inner side of the collection bottle 1 through the liquid inlet groove 7. The gastric fluid in the collection bottle 1 will enter the sample collection tube 6 through the liquid catheter 4 for storage.

[0035] Working principle: when in use, the circular box 22 and the liquid extraction hose 16 are sent into the sheep rumen. Under the buoyancy of the two floating blocks 23, the circular box 22 will float on the surface of the gastric fluid. At the same time, under the gravity of the counterweight box 19, the counterweight box 19 will pull the movable tube 17 to rotate, so that the counterweight box 19 is always located in the gastric fluid. By pulling the T-shaped push rod 13 to move, the sealing slide 11 is driven to move. When the sealing slide 11 moves, the return spring 12 is compressed. At this time, the gastric fluid in the sheep rumen is sucked into the counterweight box 19 when the sealing slide 11 moves. The gastric fluid entering the counterweight box 19 will be filtered by the filter plate 18, and the gastric fluid will then enter the annular connecting plate 25 through the movable tube 17, and finally enter the collecting bottle 1 through the liquid extraction hose 16 and the first connecting tube 2 for storage.

[0036] When the push on the T-type push rod 13 is released, the sealing slide 11 will return to its initial position under the elastic force of the return spring 12. At the same time, the air entering the connecting box 14 will be discharged into the external environment through the second one-way valve 10. When the T-type push rod 13 is pulled outward again, the sealing slide 11 will move again, so that the gastric fluid is drawn into the collecting bottle 1. When the filter plate 18 is blocked, the operator will generate resistance when pulling the T-type push rod 13. At this time, the valve 15 is closed and the two three-way valves 8 are opened, so that the airway 9 is connected to the two liquid extraction hoses 16 respectively. At this time, the pull on the T-type push rod 13 is released, the sealing slide 11 moves to send the gas into the airway 9, and finally discharged from the counterweight box 19, so that the impurities blocked in the filter plate 18 are blown away, solving the blockage problem of the filter plate 18;

[0037] When a small dose of gastric fluid is needed for testing, the screw cap 5 is opened and the upper end of the sample collecting tube 6 is screwed to the internal thread 26 in the connecting cavity 27. At this time, as the sample collecting tube 6 continues to move upward, the liquid guide tube 4 will move upward along the connecting cavity 27, and the liquid guide tube 4 will be connected to the inner side of the collecting bottle 1 through the liquid inlet groove 7. The gastric fluid in the collecting bottle 1 will enter the sample collecting tube 6 through the liquid guide tube 4 for storage. After the storage is completed, the sample collecting tube 6 is unscrewed and the screw cap 5 is screwed back on the upper end of the sample collecting tube 6.
