Description

Technical Field

[0001] The present invention relates to the technical field of sample collection, and in particular to a sample collection device for anatomical examination. Background Art

[0002] There are many types of animal diseases, and the symptoms may be similar. Accurate diagnosis is the prerequisite for effective treatment. By collecting tissue using a sample collection device for anatomical examination, veterinarians can observe the cell morphology of the tissue under a microscope and look for pathogens, thereby accurately determining the type of disease, such as whether it is mycoplasma pneumonia or Pasteurella pneumonia.

[0003] After the animal is dissected, the sample to be examined is revealed. For some samples connected to other tissues, the examiner needs to cut them off with a knife and then use tweezers to place them into a glass test tube to complete the collection. However, it is difficult to use tweezers to pick up irregularly shaped or large samples. The tweezers have a limited coverage area. To ensure that the sample can be picked up, the area in direct contact with the tweezers will be squeezed when clamped. The larger the sample, the greater the squeezing force, making the clamped area susceptible to damage and deformation. For longer tissue samples, you need to first clamp a portion of the tissue sample and insert it into the test tube. After releasing it, clamp the remaining portion and insert it into the test tube again. However, when clamping the tissue sample and dragging it toward the test tube, due to its length, its weight will be concentrated in the area in contact with the tweezers, making the tissue more likely to break after being clamped. In order to solve the above problems, there is a collector in the existing technology, in which a rebounding air pump ball is connected to one end of the test tube. When the user squeezes the air pump ball, the gas inside the air pump ball is discharged and is in a compressed state. After releasing the air pump ball, the air pump ball relies on its own elasticity to rebound and generate suction, thereby sucking the sample into the tube. Although this method solves the problem of damaging the sample tissue, the suction time is limited. The suction is only short-term during the time when the air pump ball rebounds. For longer sample tissues, it cannot be guaranteed that they can be completely sucked in. If the air pump ball is squeezed again to store suction, the tissue sample will be blown out.

[0007] The outer wall of the gasket is connected to the air bag filter screen, and the outer wall of the gasket is connected to the air bag filter screen.

[0008] Furthermore, an outer tube is provided on the sample test tube, one end of the outer tube is open and connected to a squeezable first air pump ball, and the other end opening is gradually narrowed. There is a gap between the outer tube and the sample test tube, and the gap is divided into a gas channel cavity by two partitions.

[0009] Furthermore, a second air pump ball is arranged inside the first air pump ball, and a partial area of ​​the outer wall of the second air pump ball is connected to the inner wall of the first air pump ball. An air transfer hose is connected between the second air pump ball and one of the squeezing balls. One end of the air transfer hose extends to the interior of the second air pump ball, and the outer wall of the air transfer hose is connected to the inner wall of the second air pump ball. The other end of the air transfer hose passes through the cavity and is inserted into the arc-shaped support plate, and then extends to the interior of the squeezing ball, and the outer wall of the air transfer hose is connected to the inner wall of the squeezing ball.

[0010] Furthermore, a connecting sleeve is installed on the inner wall of the cavity, the connecting sleeve has a first opening, the first opening is connected to the inside of the cavity, the connecting sleeve has a second opening, the inner wall of the second opening is connected to an inflatable bag, the inflatable bag is made of elastic material, the outer wall of the inflatable bag is against the squeezing ball, and the first air pump ball is connected to a one-way valve.

[0011] Furthermore, the first air pump ball is provided with a circular opening, and a connecting tube is connected between the second air pump ball and the circular opening, one end of the connecting tube extends to the interior of the second air pump ball and is connected with the interior of the second air pump ball, the outer wall of the connecting tube is connected to the inner wall of the second air pump ball, the bottom end of the connecting tube is connected with the circular opening and the outer diameter of the bottom end of the connecting tube is smaller than the circular opening, and the circular opening is connected with a one-way valve.

[0013] Furthermore, the inner wall of the external joint and the outer wall of the internal joint are integrally formed with threaded lines, the internal joint is threadedly connected to the external joint, and two fixing rods are installed on the inner wall of the internal joint. The outer walls of the fixing rods are against the outer wall of the air hose, and the two fixing rods are close to each other in the upper and lower positions, squeezing the air hose into a flat shape. The outer wall of the first air pump ball is drawn with a marking line, and the second air pump ball is located in the area within the marking line.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the squeezing ball is driven to swing, which moves and squeezes the rubber tube, generating a thrust on the sample tissue in the diaphragm, pushing the sample toward the sample tube, and the squeezing ball scrapes the diaphragm to deform it. Due to the characteristics of rubber, the force generated by the deformation can act on the sample tissue. The swing of the squeezing ball drives the support rod to rotate, and the trigger part is started. When the squeezing ball is on the right, the trigger part deflates the corrugated rubber air bag, the support rod moves downward, and the squeezing ball is closer to the diaphragm; when the squeezing ball swings to the left, the air bag bulges, the support rod rises, and the squeezing ball no longer squeezes the sample.

[0015] 2. In the present invention, initially, there is air in the first air pump ball and the cavity. When the first air pump ball is squeezed, the gas enters the cavity and blows toward the squeezing ball through the cavity between the arc-shaped support plates, pushing it to the right along the rubber tube, pushing the sample tissue in the diaphragm toward the sample tube. The rubber tube can transmit the deformation force to push the sample. When the air pump ball is released, the gas flows back, and the squeezing ball returns to its original position and lifts up. Repeated squeezing of the air pump ball can make the squeezing ball move back and forth, continuously pushing the sample tissue into the sample tube.

[0016] 3. In the present invention, part of the second air pump ball is connected to the inner wall of the first air pump ball. The air transfer hose is made of silicone, and its outer wall is fixed to the inner wall of the second air pump ball. The other end passes through the cavity and is inserted into the squeezing ball and fixed to its inner wall. When encountering fine sample tissue, the second air pump ball is squeezed, and the gas through the air transfer hose causes the squeezing ball to expand. The greater the squeezing force, the greater the squeezing ball expands, which can squeeze the rubber tube to narrow its entrance, making it easier to push fine sample tissue.

[0019] 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.

[0020] The present invention provides a technical solution: See Figures 1-9 As shown, a sample collection device for anatomical examination includes a sample tube 28, which is closed at one end and open at the other end, and a rubber tube 7, one end of which is fixedly connected to the inner wall of the sample tube 28, and the corresponding side walls of the two form a receiving cavity; two swingable squeezing balls 11 are symmetrically arranged in the receiving cavity about the central axis of the rubber tube 7. The squeezing balls 11 are in contact with the rubber tube 7 in the initial state and are used to squeeze the rubber tube 7 to produce deformation when swinging, thereby providing a driving force to push the sample tissue into the sample tube 28; two rotating rods 15 are respectively arranged at the corresponding In the accommodating cavity, the outer side of the rotating rod 15 is provided with a relatively rotating support rod 12, one end of the support rod 12 is connected to the squeezing ball 11; the adjusting mechanism includes at least a corrugated rubber squeezing bag 18 arranged inside the support rod 12, the two ends of the corrugated rubber squeezing bag 18 are respectively connected to the side walls opposite to the support rod 12 and the rotating rod 15, and a trigger portion connected to the corrugated rubber squeezing bag 18, which is used to supply or exhaust air to the corrugated rubber squeezing bag 18 when the support rod 12 swings, so that the squeezing ball 11 is away from the rubber tube 7 when it is stretched, and close to the rubber tube 7 when it is contracted.

[0021] The squeezing ball 11 is driven to swing, and when the squeezing ball 11 moves, it squeezes and pushes the rubber tube 7. When the sample tissue is located at the inlet on the left side of the rubber tube 7, the gas blows the squeezing ball 11 from the left side of the squeezing ball 11 to move rightward, and then the squeezing ball 11 will move from left to right, and generate a rightward thrust on the rubber tube 7 and the sample tissue inside the rubber tube 7, thereby pushing the sample tissue inside the rubber tube 7 into the sample test tube 28. When the squeezing ball 11 scrapes the outer wall of the rubber tube 7, the rubber tube 7 will deform. Due to the elasticity and flexibility of the rubber, the force generated by this deformation will be transmitted inside the material of the rubber tube 7. The deformation of the rubber tube 7 will change the shape and pressure distribution of its internal space. Even if one end of the rubber tube 7 is connected to the outside world, the squeezing force generated by its deformation can still act on the product tissue. For example, when the squeezing ball 11 moves and scrapes to squeeze a part of the rubber tube 7 inward, it is like a local contraction wave propagating toward the sample tissue, producing a pushing effect on the sample tissue, and squeezing the sample tissue toward the sample test tube 28. When the squeezing ball 11 swings, the support rod 12 swings together, and the support rod 12 rotates along the outer wall of the rotating rod 15. When the support rod 12 swings, the trigger part is activated. When the squeezing ball 11 is located on the right side, the trigger part evacuates the corrugated rubber squeezing bag 18, causing the corrugated rubber squeezing bag 18 to shrink, causing the support rod 12 to move downward a certain distance, so that the squeezing ball 11 is closer to the rubber tube 7. When the squeezing ball 11 swings to the left, the corrugated rubber squeezing bag 18 bulges, causing the support rod 12 to rise. At this time, the squeezing ball 11 no longer squeezes the tissue sample.

[0022] See Figure 4 The adjustment mechanism also includes a square opening 16 opened by the support rod 12, one end of the corrugated rubber squeeze bag 18 is fixedly connected to the inner top wall of the square opening 16, and the end of the corrugated rubber squeeze bag 18 away from the square opening 16 is fixedly connected to a ring 17, which is located inside the square opening 16 and is rotatably connected to the outer wall of the rotating rod 15.

[0023] When the corrugated rubber squeeze bag 18 contracts, the inner top wall of the square opening 16 will be close to the collar 17 , and the support rod 12 will pass through the square opening 16 and slide along the collar 17 .

[0024] See Figure 4-Figure 5 The triggering part includes two arc-shaped sleeves 21 arranged between the two support rods 12. A slide groove 22 is opened in the arc-shaped sleeve 21. An air supply hose 19 is connected between the slide groove 22 and the corrugated rubber squeeze air bag 18. One end of the air supply hose 19 is inserted into the support rod 12 and extends into the interior of the corrugated rubber squeeze air bag 18 and is fixedly connected to the inner wall of the corrugated rubber squeeze air bag 18. The air supply hose 19 is connected to the corrugated rubber squeeze air bag 18; The other end of the gas hose 19 is inserted through the arc sleeve 21 and extends to the inside of the slide 22. The outer wall of the gas hose 19 is fixedly connected to the inner wall of the slide 22. The gas hose 19 is communicated with the slide 22. A piston 24 is slidably connected in the slide 22. The outer wall of the piston 24 is fixedly connected to an arc-shaped slide rod 23. A through opening 25 is provided at the bottom end of the arc sleeve 21. The end of the arc slide rod 23 away from the piston 24 passes through the through opening 25 and extends to the outside of the arc sleeve 21. A connecting plate 27 is fixedly connected between the bottom ends of the two arc slide rods 23. A mounting plate 26 is fixedly connected between the outer walls of the two support rods 12. The outer wall of the mounting plate 26 is against the inner bottom wall of the connecting plate 27. Two fixing plates 20 are fixedly installed on the top of the arc sleeve 21. The top of the fixing plate 20 is fixedly connected to the inner top wall of the arc support plate 3.

[0025] Both ends of the rotating rod 15 are fixedly connected to the inner wall of the arc-shaped support plate 3, and the fixing plate 20 is also fixedly connected to the inner wall of the arc-shaped support plate 3. The fixing plate 20 is fixed on the arc-shaped support plate 3 to provide a stable supporting force for the arc-shaped sleeve 21. The arc-shaped sleeve 21 is located between the two support rods 12 and is not connected to the support rods 12. One end of the air supply hose 19 is connected to the inside of the chute 22 and is inserted through the arc-shaped sleeve 21 to extend to the outside of the arc-shaped sleeve 21. Then the other end is inserted through the support rod 12 and extends to the corrugated rubber squeeze bag 18. Inside, the top of the corrugated rubber squeeze bag 18 is fixedly connected to the inner top wall of the square opening 16, and the bottom end is fixedly connected to the outer wall of the collar 17. The inner wall of the collar 17 is rotatably connected to the outer wall of the rotating rod 15. The collar 17 is located inside the square opening 16 but is not connected to the square opening 16. It only abuts against the inner wall of the square opening 16. The area where the air hose 19 is inserted into the support rod 12 is fixedly connected to the inner wall of the support rod 12, and the area where the air hose 19 is inserted into the arc sleeve 21 is fixedly connected to the inner wall of the arc sleeve 21. The outer wall of the piston 24 is tightly against the inner wall of the slide groove 22, and the arc-shaped slide rod 23 is not connected to the slide groove 22 and the arc-shaped sleeve 21, so the arc-shaped slide rod 23 can move inside the slide groove 22, and the air supply hose 19 is connected to the slide groove 22 and the interior of the corrugated rubber squeeze bag 18. The top of the connecting plate 27 is fixedly connected to the bottom ends of the two arc-shaped slide rods 23, and can be fixed together by bonding. The outer walls of both sides of the mounting plate 26 are also fixedly connected to the outer walls of the two support rods 12 respectively, and the specific connection method can also be bonding. The air supply hose 19 is also a hose, and can specifically be made of silicone. When the support rod 12 swings, the air supply hose 19 can deform or move to adapt to the position of contact with the support rod 12; When the inflatable bag 10 expands and pushes the squeezing ball 11, the squeezing ball 11 and the support rod 12 will swing along the collar 17. When the bottom end of the support rod 12 and the squeezing ball 11 swing from left to right, the support rod 12 drives the mounting plate 26 to swing together, and the mounting plate 26 pushes the connecting plate 27. Figure 5As shown in FIG, the swing trajectory of the mounting plate 26 is the same as that of the support rod 12 and the squeeze ball 11, so the connecting plate 27 is pushed by the mounting plate 26 to move to the lower right, and then the arc-shaped slide rod 23 drives the piston 24 to slide along the slide groove 22; When the squeeze ball 11 is located Figure 3 When the piston 24 is on the left side, the position of the piston 24 is as follows Figure 5 When the squeezing ball 11 is swung to the right, the piston 24 moves toward the opening 25, and then the gas in the gas hose 19 is extracted, and the gas in the gas hose 19 is extracted. The gas in the corrugated rubber squeeze bag 18 is extracted, and the corrugated rubber squeeze bag 18 shrinks. When the corrugated rubber squeeze bag 18 shrinks, the inner top wall of the square opening 16 is close to the ring 17, and the support rod 12 passes through the square opening 16 and slides along the ring 17, so that the support rod 12 moves part way to the lower left. The squeezing ball 11 is moved closer to the rubber tube 7, and when the first air pump ball 2 is released, the inflatable bag 10 no longer conflicts with the squeezing ball 11, and the corrugated rubber squeezing bag 18 automatically rebounds by its own elastic force and pushes the inner top wall of the square opening 16 away from the collar 17 again, and the square opening 16 also moves along the collar 17, and the support rod 12 moves upward by an end distance, lifting the squeezing ball 11 a part of the distance, so that the squeezing ball 11 no longer squeezes the tissue sample, and then the squeezing ball 11 and the support rod 12 swing back to the initial position, that is, Figure 3 Center left position; After the support rod 12 is lifted upward, the squeezing ball 11 no longer squeezes the rubber tube 7. At this time, when the squeezing ball 11 moves back to its original position, it will not push the sample tissue in the rubber tube 7 out of the outside of the rubber tube 7. The corrugated rubber squeezing bag 18 will re-absorb the gas inside the chute 22 through the gas hose 19 during the rebound process. Then the piston 24 and the arc-shaped slide rod 23 will move toward the top wall of the chute 22 again, and the connecting plate 27 will move together with the arc-shaped slide rod 23, and drive the mounting plate 26 to move together, so that the support rod 12 and the squeezing ball 11 will move back to their initial positions. Figure 2 The position in.

[0026] See Figures 1-9 An outer tube 1 is provided on the sample test tube 28. One end of the outer tube 1 is open and connected to a squeezable first air pump ball 2. The opening at the other end is gradually narrowed. There is a gap between the outer tube 1 and the sample test tube 28. The gap is divided into a gas channel cavity 8 by two partitions.

[0027] like Figure 6As shown in the figure, two partitions are located between the outer tube 1 and the sample tube 28, one side outer wall of the partition is fixedly connected to the inner wall of the outer tube 1, and the other side outer wall is fixedly connected to the outer wall of the sample tube 28. The two partitions divide the gap between the outer tube 1 and the sample tube 28 into two upper and lower cavities 8. The first air pump ball 2 is sleeved on one end of the outer tube 1 and the sample tube 28. The inner wall of the first air pump ball 2 is fixedly connected to the outer wall of the outer tube 1, forming a sealing effect inside the first air pump ball 2. The first air pump ball 2 itself is made of an elastic and recoverable material, such as rubber. In the initial state, the first air pump ball 2 and the cavity 8 are both filled with gas. When the first air pump ball 2 is squeezed, the gas inside the first air pump ball 2 will enter the cavity 8. One end of the outer tube 1 and the open end of the sample test tube 28 are fixedly mounted with an arc-shaped support plate 3. One end of the arc-shaped support plate 3 is narrowed, and the side wall of the edge of the arc-shaped support plate 3 is fixedly connected to the outer wall of the rubber tube 7. The two arc-shaped support plates 3 are fixed to the end of the outer tube 1 away from the first air pump ball 2, and the ends of the two arc-shaped support plates 3 away from the outer tube 1 are close to each other. Therefore, the arc-shaped support plates 3 are as shown in FIG. Figure 2 The middle is the tilted state; The two arc-shaped support plates 3 do not contact each other, and a gap is left between them. The edge wall of the arc-shaped support plate 3 is fixedly connected to the outer wall of the rubber tube 7, so that a closed area can be formed between the rubber tube 7 and the inner wall of the arc-shaped support plate 3. The material of the rubber tube 7 is soft. Before entering the sample tube 28, the sample tissue must first enter the rubber tube 7, and then enter the sample tube 28 from the rubber tube 7. A cavity 8 is left between the outer tube 1 and the sample tube 28, as well as between the arc-shaped support plate 3 on the outer tube 1 and the arc-shaped support plate 3 on the sample tube 28. Therefore, when the first air pump ball 2 is squeezed and the overflowed gas enters the cavity 8, it will follow the cavity 8 and enter the cavity 8 between the two arc-shaped support plates 3. The outlet of the cavity 8 corresponds to the squeezing ball 11, so the gas will be blown onto the squeezing ball 11, and then blow the squeezing ball 11 to move along the rubber tube 7. When the squeezing ball 11 moves, it will squeeze and thrust the rubber tube 7. like Figure 3 As shown, the gas outlet of the cavity 8 in the arc-shaped support plate 3 is located on the left side of the squeezing ball 11, and the sample tube 28 is on the right side. Therefore, when the sample tissue is located at the inlet on the left side of the rubber tube 7, the gas blows the squeezing ball 11 from the left side to move it to the right. Then, the squeezing ball 11 moves from left to right and generates a rightward thrust on the rubber tube 7 and the sample tissue in the rubber tube 7, thereby pushing the sample tissue in the rubber tube 7 into the sample tube 28. The rubber tube 7 acts as a flexible connection between the sample tube 28 and the external environment. When the squeezing ball 11 scrapes the outer wall of the rubber tube 7, the rubber tube 7 deforms. Due to the elasticity and flexibility of the rubber, the force generated by this deformation is transmitted within the material of the rubber tube 7. The deformation of the rubber tube 7 changes the shape and pressure distribution of its internal space. Even if one end of the rubber tube 7 is connected to the outside world, the squeezing force generated by its deformation can still act on the product tissue. For example, when the squeezing ball 11 moves and scrapes, squeezing a portion of the rubber tube 7 inward, it is like a localized contraction wave propagating toward the sample tissue, producing a pushing effect on the sample tissue and squeezing the sample tissue toward the sample tube 28. When the first air pump ball 2 is released, the first air pump ball 2 begins to rebound due to its own elasticity. During the rebound process, the gas re-enters the first air pump ball 2 through the cavity 8. When the gas no longer pushes the squeezing ball 11, the squeezing ball 11 moves back to its original position and is lifted upward during the return process to prevent the squeezing ball 11 from pushing the sample tissue back to the entrance of the rubber tube 7. Therefore, the user only needs to repeatedly squeeze the first air pump ball 2 to make the squeezing ball 11 repeatedly move back and forth, thereby continuously pushing the sample tissue into the sample tube 28 .

[0028] See Figure 6 A second air pump ball 31 is provided inside the first air pump ball 2, and a partial area of ​​the outer wall of the second air pump ball 31 is fixedly connected to the inner wall of the first air pump ball 2. An air transfer hose 30 is connected between the second air pump ball 31 and one of the squeezing balls 11. One end of the air transfer hose 30 extends to the interior of the second air pump ball 31, and the outer wall of the air transfer hose 30 is fixedly connected to the inner wall of the second air pump ball 31. The other end of the air transfer hose 30 passes through the cavity 8 and is inserted into the arc-shaped support plate 3, and then extends to the interior of the squeezing ball 11, and the outer wall of the air transfer hose 30 is fixedly connected to the inner wall of the squeezing ball 11.

[0029] Part of the outer wall of the second air pump ball 31 is fixedly connected to the inner wall of the first air pump ball 2, and the remaining area is not connected to the first air pump ball 2, so it will not affect the expansion and contraction of the second air pump ball 31. Since the second air pump ball 31 will deform after being squeezed, the air transfer hose 30 is made of silicone and can move according to the deformation of the second air pump ball 31. The outer wall of the air transfer hose 30 is fixedly connected to the inner wall of the second air pump ball 31 to ensure that the air transfer hose 30 will not fall off from the second air pump ball 31. The other end of the air transfer hose 30 passes through the cavity 8 and is inserted into the interior of the arc-shaped support plate 3. Then, the end of the air transfer hose 30 inserted into the interior of the arc-shaped support plate 3 is inserted into the interior of the squeezing ball 11. The outer wall of the air transfer hose 30 is fixedly connected to the inner wall of the squeezing ball 11 to ensure that the air transfer hose 30 will not fall off from the squeezing ball 11. Since the squeezing ball 11 needs to move, the air transfer hose 30 made of silicone can move with the movement of the squeezing ball 11. When encountering a thinner sample tissue, the second air pump ball 31 can be squeezed to allow the gas in the second air pump ball 31 to enter the gas transfer hose 30, and then enter the squeezing ball 11 through the gas transfer hose 30. It should be noted that the squeezing ball 11 can be an elastic inflatable component such as an air bag, so it can cause the squeezing ball 11 to expand. The harder the second air pump ball 31 is squeezed, the more gas enters the squeezing ball 11, and the squeezing ball 11 expands. After the squeezing ball 11 expands, it will squeeze the rubber tube 7 and shrink the entrance of the rubber tube 7, ensuring that the squeezing ball 11 can push the sample tissue after moving.

[0030] See Figure 1-Figure 7 A connecting sleeve 9 is fixedly installed on the inner wall of the cavity 8, and the connecting sleeve 9 has a first opening 901, which is connected to the inside of the cavity 8. The connecting sleeve 9 has a second opening 902, and the inner wall of the second opening 902 is fixedly connected to an inflatable bag 10, which is made of elastic material. The outer wall of the inflatable bag 10 is against the squeezing ball 11, and the first air pump ball 2 is connected to a one-way valve 6.

[0031] The outer wall of the connecting sleeve 9 is fixedly connected to the inner wall of the cavity 8, and the first opening 901 corresponds to the cavity 8, so that the gas can directly enter the connecting sleeve 9 through the first opening 901. Figure 3 In the embodiment, since the position of the second opening 902 is aligned with the squeezing ball 11 , the inflatable bag 10 is also aligned with the position of the squeezing ball 11 and contacts and abuts against the squeezing ball 11 .

[0032] After squeezing the first air pump ball 2, the gas enters the cavity 8 and reaches the outlet of the cavity 8 located in the arc-shaped support plate 3. The gas enters the connecting sleeve 9 through the first opening 901, and then enters the inflatable bag 10 through the second opening 902. The inflatable bag 10 is a rubber-coated cloth. When the gas contacts the inflatable bag 10, it pushes the inflatable bag 10 to expand outward, causing the inflatable bag 10 to inflate. After the inflatable bag 10 inflates, it pushes the squeezing ball 11 to move. Since the first air pump ball 2 is connected to the one-way valve 6, the one-way valve 6 allows gas to enter the first air pump ball 2 only from the outside and prevents gas from going out of the first air pump ball 2. Therefore, after the one-way valve 6 is installed, the first air pump ball 2 is squeezed repeatedly, and the external gas will continue to enter the first air pump ball 2 through the one-way valve 6, and the first air pump ball 2 will also send the gas into the cavity 8, and finally enter the inflatable bag 10 through the connecting sleeve 9, so that the inflatable bag 10 is continuously expanded. When the sample tissue is collected in the sample test tube 28, the inflatable bag 10 is expanded, and the inflatable bag 10 continues to expand and squeezes the rubber tube 7. With the continuous input of gas, the inflatable bag 10 expands until the entrance of the rubber tube 7 is sealed, and then the sample test tube 28 is blocked to prevent the sample tissue from falling out. When the sample tissue in the sample tube 28 needs to be taken out, the one-way valve 6 is removed and the first air pump ball 2 is squeezed to release the excess gas, so that the inflatable bag 10 shrinks and the inlet of the rubber tube 7 is opened.

[0033] See Figure 7 The first air pump ball 2 is provided with a circular opening 33, and a connecting pipe 32 is connected between the second air pump ball 31 and the circular opening 33. One end of the connecting pipe 32 extends to the interior of the second air pump ball 31 and is connected to the interior of the second air pump ball 31. The outer wall of the connecting pipe 32 is fixedly connected to the inner wall of the second air pump ball 31, and the bottom end of the connecting pipe 32 is connected to the circular opening 33 and the outer diameter of the bottom end of the connecting pipe 32 is smaller than the circular opening 33. The circular opening 33 is connected to the one-way valve 6, and the outer wall of the connecting pipe 32 is fixedly connected to the inner wall of the circular opening 33.

[0034] The circular opening 33 is the air inlet of the arc-shaped support plate 3. The external gas must first enter the one-way valve 6, then enter the circular opening 33 through the one-way valve 6, and finally reach the interior of the first air pump ball 2 and the connecting pipe 32 from the circular opening 33. When the second air pump ball 31 is squeezed to add air to the squeezing ball 11, the second air pump ball 31 extracts gas through the connecting pipe 32, and the gas reaches the circular opening 33 from the one-way valve 6, then enters the connecting pipe 32 through the circular opening 33, and finally enters the interior of the second air pump ball 31. Since the one-way valve 6 only allows gas to enter but cannot exit, squeezing the second air pump ball 31 can make the gas in the second air pump ball 31 be poured into the squeezing ball 11, causing the squeezing ball 11 to expand. When squeezing the second air pump ball 31, due to the air intake structure of the one-way valve 6, the connecting pipe 32 will not give priority to extracting the gas inside the first air pump ball 2, but will only directly extract the external gas through the one-way valve 6. When squeezing the first air pump ball 2, the one-way valve 6 will also be used to extract the external gas.

[0035] See Figure 1 The outer wall of the first air pump ball 2 is fixedly connected to the external joint 4, and the inner wall of the circular opening 33 is fixedly connected to the air guide hose 13. The circular opening 33 is connected to the inside of the air guide hose 13. The end of the air guide hose 13 away from the circular opening 33 corresponds to the one-way valve 6. One end of the one-way valve 6 is fixedly installed with an internal joint 5, and the internal joint 5 is plugged into the external joint 4.

[0036] One end of the one-way valve 6 is fixedly connected to one end of the inner joint 5, and the inner joint 5 can be inserted into the outer joint 4. Before the inner joint 5 is inserted into the outer joint 4, the gas hose 13 must be passed between the two fixing rods 14. The circular opening 33 is fixedly connected to one end of the gas hose 13. Therefore, when the inner joint 5 and the one-way valve 6 are connected to the outer joint 4, the gas first enters the gas hose 13, and then reaches the circular opening 33 through the gas hose 13. The gas hose 13 is made of silicone. When air intake is not needed, the inner joint 5 is rotated along the inner side of the outer joint 4. When the inner joint 5 rotates, the two fixing rods 14 are driven to rotate. The positions of the two fixing rods 14 are close. Therefore, when the gas hose 13 is located between the two fixing rods 14, the contact portion of the gas hose 13 with the fixing rods 14 will be squeezed into a flat shape by the fixing rods 14, but ventilation is still possible. As the inner joint 5 and the one-way valve 6 are rotated, the fixing rod 14 exerts a torsional force on the gas guide hose 13, causing the gas guide hose 13 to be twisted together. At this time, the gas cannot smoothly pass through the gas guide hose 13 into the first air pump ball 2 and the connecting tube 32. At this time, the first air pump ball 2 can be repeatedly squeezed, causing the squeezing ball 11 to repeatedly swing and push the sample tissue in the rubber tube 7. When the inner joint 5 is twisted in the opposite direction, the fixing rod 14 rotates in the opposite direction to loosen the gas guide hose 13. At this time, the gas guide hose 13 is connected to the one-way valve 6. After squeezing the first air pump ball 2, the external gas can enter the gas guide hose 13 through the one-way valve 6 and reach the circular opening 33, and then enter the first air pump ball 2. At this time, repeatedly squeezing the first air pump ball 2 can cause the inflatable bag 10 to continue to expand; The inlet of the rubber tube 7 is sealed, and the second air pump ball 31 is squeezed at this time. The external gas can also enter the air guide hose 13 through the one-way valve 6, and then enter the connecting pipe 32 and the second air pump ball 31. Then, the gas enters the squeezing ball 11 through the squeezed second air pump ball 31, causing the squeezing ball 11 to expand. When the inner joint 5 is unscrewed, the end of the air guide hose 13 away from the circular opening 33 will be directly connected to the outside world. At this time, after squeezing the first air pump ball 2, some gas will enter the outside world through the circular opening 33, and the gas that inflated the inflatable bag 10 will also return to the first air pump ball 2, causing the inflatable bag 10 to shrink again, thereby opening the inlet channel of the rubber tube 7; Squeezing the second air pump ball 31 can also cause part of the gas in the squeeze ball 11 to be withdrawn into the second air pump ball 31 and reach the circular opening 33 through the connecting tube 32 and then enter the outside.

[0037] See Figure 1The inner wall of the external joint 4 and the outer wall of the internal joint 5 are integrally formed with thread lines. The internal joint 5 is threadedly connected to the external joint 4. Two fixing rods 14 are fixedly installed on the inner wall of the internal joint 5. The outer wall of the fixing rod 14 is against the outer wall of the air guide hose 13, and the two fixing rods 14 are close to each other in the upper and lower positions, squeezing the air guide hose 13 into a flat shape. The outer wall of the first air pump ball 2 is depicted with a marking line 29, and the second air pump ball 31 is located in the area within the marking line 29.

[0038] The outer wall of the inner joint 5 and the inner wall of the outer joint 4 are integrally formed with matching thread lines, which makes it convenient to rotate the inner joint 5 and the one-way valve 6 to screw the inner joint 5 into the outer joint 4, making the connection between the inner joint 5 and the outer joint 4 more stable and not easy to fall off. A marking line 29 can be drawn on the first air pump ball 2 with a pen. The area within the marking line 29 corresponds to the position of the second air pump ball 31, which makes it convenient for the user to clearly know where the second air pump ball 31 is located in the first air pump ball 2, and then to accurately squeeze the second air pump ball 31.
