Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a rapid thrombus detection device. Background Art

[0002] Invisible thrombus mainly refers to the thrombus that has not yet formed in the body, but has the conditions for thrombus formation. Detection of invisible thrombus can provide a reference for the prevention, treatment and diagnosis of cardiovascular and cerebral thrombosis.

[0003] In the prior art, the temperature controlled inside the thrombus detector is the same as the human body temperature. The blood to be tested is injected into the artificial blood vessel, and is usually centrifuged for 10 minutes in the thrombus detector to gather the thrombotic factors carried in the blood to be tested. The blood in the artificial blood vessel is then evenly poured onto the filter paper, and the degree of thrombus formation is determined based on the length, dry weight, and wet weight of the thrombus.

[0004] In practice, the time from drawing blood and removing the needle to loading the blood into the artificial blood vessel, loading the instrument and starting it should be controlled within 1 minute, and the shorter the time, the better, to avoid the coagulation reaction of the blood to be tested, the pre-production of blood clots, and affecting the test results. During operation, although the blood tester is usually equipped with four test ports, each test port can hold three portions of blood to be tested, but in order to ensure the test results, it can be started after a portion of blood to be tested is placed in a test port to avoid waiting for the subsequent blood to be tested for too long, which affects the test results. Therefore, a blood tester can test a small amount of blood, resulting in low efficiency. Summary of the invention

[0087] See also Figures 1 to 9 This embodiment provides a rapid thrombus detection device, including a frame 10, a housing 20, a temperature control device, a transmission column 30, a blood vessel fixing frame 40 and a driving mechanism 50.

[0088] The housing 20 is disposed on the frame 10 , and has an openable and closable inlet 21 and an openable and closable outlet 22 .

[0089] The temperature control device is arranged in the housing 20, and is used to control the temperature in the housing 20. The temperature control device adopts the existing technology and is not described here. The temperature control device is used to ensure the constant temperature in the housing, and its temperature setting is consistent with the temperature setting required by the thrombus detector in the existing technology.

[0090] The two ends of the transmission column 30 pass through the inlet 21 and the outlet 22 respectively, and the two ends of the transmission column 30 can be connected to the frame 10, and one of the two ends of the transmission column 30 can be connected to the frame 10. A plurality of blood vessel fixing frames 40 can be provided, and the blood vessel fixing frames 40 are used to fix the artificial blood vessels. The blood vessel fixing frames 40 can be sleeved on the transmission column 30, and the blood vessel fixing frames 40 are threadedly connected to the transmission column 30. The driving mechanism 50 is used to drive the blood vessel fixing frames 40 on the transmission column 30 to rotate and feed.

[0091] In this embodiment, the medical staff installs the annular artificial blood vessel loaded with blood on the blood vessel fixing frame 40, and then disconnects one end of the transmission column 30 from the frame 10, inserts the blood vessel fixing frame 40 from the end of the transmission column 30 and rotates it. After the blood vessel fixing frame 40 and the transmission column 30 are successfully threadedly connected, the annular artificial blood vessel on the blood vessel fixing frame 40 is coaxial with the transmission column 30.

[0092] Then, the ends of the transmission column 30 that are detached from the frame 10 are reconnected, and the frame 10 supports the two ends of the transmission column 30. The driving mechanism 50 drives the blood vessel fixing frame 40 on the transmission column 30 to rotate. When the blood vessel fixing frame 40 rotates, it moves along the axial direction of the transmission column 30. During this process, the temperature inside the shell is constant. The process of the blood vessel fixing frame 40 moving from one end of the transmission column 30 to the other end is set to take about 10 minutes, so that the thrombotic factors inside it are accumulated. Multiple blood vessel fixing frames 40 can be transported and rotated at the same time through the transmission column 30, and the blood samples to be tested in the annular artificial blood vessels on multiple blood vessel fixing frames 40 can be processed at the same time, thereby improving the efficiency of thrombus detection.

[0093] In one embodiment, the blood vessel fixing frame 40 includes a blood vessel fixing ring 41 , a matching ring 42 and a limiting ring 43 .

[0094] The blood vessel fixing ring 41 can be sleeved on the transmission column 30, and the blood vessel fixing ring 41 can be threadedly connected to the transmission column 30. The matching ring 42 is coaxially connected to one end of the blood vessel fixing ring 41. The limiting ring 43 can be threadedly sleeved on one end of the blood vessel fixing ring 41 away from the matching ring 42, and the outer ring of the limiting ring 43 extends a retaining ring 44 toward the matching ring 42.

[0095] The blood vessel fixing ring 41 is used to support the annular artificial blood vessel sleeved on its outer wall; the limiting ring 43 and the matching ring 42 can clamp the artificial blood vessel therebetween; and the retaining ring 44 can limit the outer ring of the artificial blood vessel.

[0096] In this embodiment, after the blood to be tested is injected into the annular artificial blood vessel, the annular artificial blood vessel is put on the blood vessel fixing ring 41 and abutted against the matching ring 42 on one side, and then the limiting ring 43 is rotated and threadedly sleeved on the blood vessel fixing ring 41. At this time, the limiting ring 43 and the matching ring 42 clamp and fix the annular artificial blood vessel from both sides. In addition, since the annular artificial blood vessel is obtained by bending an artificial blood vessel and docking the two ends, there is a risk of the docking ends being separated. The retaining ring 44 connected to the limiting ring 43 can limit the awakening artificial blood vessel from the outer wall of the annular artificial blood vessel, thereby avoiding this situation.

[0097] In one embodiment, the outer ring of the matching ring 42 is connected to a radially arranged protrusion 45 , and more than one protrusion 45 is provided.

[0098] The driving mechanism 50 includes a driving sleeve 51 , a driving rod 52 , a driving gear 53 and a motor 54 .

[0099] The driving sleeve 51 is rotatably disposed in the housing, and is coaxially sleeved outside the transmission column 30. A rack is disposed along the circumferential direction on the outer wall of the driving sleeve 51. Specifically, a groove along the circumferential direction is provided on the outer wall of the driving sleeve 51, and a guide ring is provided in the housing and sleeved on the groove. The guide ring supports the driving sleeve 51 by slidingly matching with the groove.

[0100] At least one driving rod 52 is provided, and the driving rod 52 is connected to the inner wall of the driving sleeve 51. The length direction of the driving rod 52 is parallel to the axial direction of the driving sleeve 51. The driving rod 52 can be located outside the outer ring of the matching ring 42 and can abut against the protrusion 45. Specifically, the side surface of the driving rod 52 can abut against the protrusion 45.

[0101] The driving gear 53 is rotatably disposed in the housing, and is meshed with a rack on the outer wall of the driving sleeve 51. The motor 54 is disposed in the housing, and the output end of the motor 54 is coaxially connected to the driving gear 53.

[0102] In this embodiment, after the vascular fixing frame 40 is screwed onto the transmission column 30, the motor 54 can drive the driving rod 52 to rotate around the transmission column 30 through the driving gear 53 and the driving sleeve 51. The driving rod 52 abuts against the protrusion 45 of the vascular fixing frame 40 during the rotation, thereby driving the entire vascular fixing frame 40 to rotate. The vascular fixing frame 40 rotates and moves along the axial direction of the transmission column 30 until the vascular fixing frame 40 is separated from the driving rod 52.

[0103] In one embodiment, the driving mechanism 50 further includes a sleeve rod 55 , a first spring 56 and a shielding plate 57 .

[0104] The sleeve rod 55 is arranged corresponding to the driving rod 52, and one end of the sleeve rod 55 is slidably sleeved on the driving rod 52 by opening a matching hole 551. The first spring 56 is located in the matching hole 551, and the two ends of the first spring 56 are respectively connected to the end of the driving rod 52 and the bottom of the matching hole 551. The shielding plate 57 is located in the opening, and the inner side of the shielding plate 57 is connected to the end of the sleeve rod 55 away from the driving rod 52. The shielding plate 57 is provided with a detection hole 571 that allows the matching ring 42 and the limit ring 43 to pass through. The side wall of the detection hole 571 is provided with a clearance notch 572 that allows the protrusion 45 to pass through. The number of the clearance notches 572 is corresponding to the number of the protrusions 45. Specifically, more than two driving rods 52 can be provided here, and correspondingly, more than two sleeve rods 55 are also provided, and the ends of more than two sleeve rods 55 are fixedly connected to the shielding plate 57.

[0105] In this embodiment, the shielding plate 57 blocks the shell to a certain extent at the opening of the shell. The blood vessel fixing frame 40 without an artificial blood vessel can be placed on the end of the transmission column 30 to cooperate with the transmission column 30 to block the detection hole 571 on the shielding plate 57, so that the opening of the shell is completely closed, thereby reducing the heat exchange between the hot air in the shell and the outside air through the opening.

[0106] During operation, the blood vessel fixing frame 40 at the end of the transmission column 30 for shielding the detection hole 571 is removed and an artificial blood vessel containing the blood to be tested is installed, and then the blood vessel fixing frame 40 is sleeved on the end of the transmission column 30. There is no thread in the end area of ​​the transmission column 30. The blood vessel fixing frame 40 needs to be moved a certain distance along the axial direction of the transmission column 30 and then rotated to be threadedly connected with the transmission column 30. When the blood vessel fixing frame 40 is threadedly connected to the transmission column 30 and moves, the shielding plate 57 rotates at the opening with the sleeve rod 55, and the clearance notch 572 on the shielding plate 57 is not aligned with the protrusion 45, so the blood vessel fixing frame 40 cannot enter the shell from the detection hole 571 through the shielding plate 57. The blood vessel fixing frame 40 first abuts against and compresses the shielding plate 57, and then the blood vessel fixing frame 40 rotates and is threadedly connected to the transmission column 30. At this time, the shielding plate 57 gradually rotates until the clearance notch 572 thereon is aligned with the protrusion 45 on the blood vessel fixing frame 40, and the blood vessel fixing frame 40 enters the detection hole 571, and the sleeve rod 55 connected to the inner wall of the shielding plate 57 abuts against the protrusion 45 during the rotation process. The rotation of the sleeve rod 55 drives the blood vessel fixing frame 40 to rotate and feed on the transmission column 30.

[0107] In one embodiment, the rapid thrombus detection device further comprises two supporting devices 60 disposed on the frame 10. The two supporting devices 60 are symmetrically arranged and can support the transmission column 30 from both ends. Both ends of the transmission column 30 are provided with connecting square holes 31.

[0108] The supporting device 60 includes a supporting rod 61 and a locking mechanism 62 .

[0109] The support rod 61 can be laterally slidably arranged on the frame 10, and the end of the support rod 61 can be slidably inserted into the corresponding connecting square hole 31. The locking mechanism 62 can lock the support rod 61 and the transmission column 30. A shielding cover 70 is connected to the support rod 61 away from the shielding plate 57 among the two support rods 61, and the shielding cover 70 can block the outlet 22 after approaching. Specifically, the shielding cover 70 can be hemispherical or have a columnar outer contour. In addition, the end of the support rod 61 inserted into the connecting square hole 31 is a pointed end, which is convenient for it to be reinserted after being detached from the connecting square hole 31.

[0110] In this embodiment, two support rods 61 can be simultaneously inserted into the connecting square hole 31 of the transmission column 30 to support the transmission column 30, and the support rods 61 and the transmission column 30 can be locked together by the locking mechanism 62. When it is necessary to place the vascular fixing frame 40 on the transmission column 30, the support rod 61 on one side of the shielding plate 57 can be unlocked, and the support rod 61 can be disengaged from the connecting square hole 31 to install the vascular fixing frame 40 on the transmission column 30, and then the support rod 61 is moved horizontally and reinserted into the corresponding connecting square hole 31. In the above process, the support rod 61 on the other side can always support the transmission column 30.

[0111] In one embodiment, a plurality of ratchet grooves 32 are formed on the inner wall of the upper side of the connecting square hole 31 and are distributed along the axial direction of the transmission column 30. A mounting cavity 611 is formed in the support rod 61; a locking hole 612 is formed on the upper side of the support rod 61 to connect the inside and the outside.

[0112] The locking mechanism 62 includes a second spring 621 , a first limiting block 622 , a guide block 623 , a second limiting block 624 and a locking block 625 .

[0113] The second spring 621 is connected to one side of the inner wall of the installation cavity 611 close to the bottom of the connecting square hole 31 .

[0114] The first limiting block 622 is connected to the second spring 621 , and the first limiting block 622 is slidably disposed in the installation cavity 611 along the axial direction of the transmission column 30 .

[0115] The guide block 623 is tiltedly disposed in the installation cavity 611 , and a higher end thereof is connected to the first limiting block 622 .

[0116] The second limit block 624 is connected to one end of the guide block 623 away from the first limit block 622, and the second limit block 624 can slide away from the second spring 621 along the axial direction of the transmission column 30. Specifically, the lower end of the guide block 623 is connected to the second limit block 624. The upper end of the locking block 625 is connected to a ratchet block 626 that can fit with the corresponding ratchet groove 32, and the locking block 625 is provided with a guide hole that slides with the guide block 623.

[0117] The ratchet block 626 is located in the locking hole 612. When the second limit block 624 moves away from the second spring 621, the locking block 625 drives the ratchet block 626 to rise and then be inserted into the corresponding ratchet groove 32 to prevent the second limit block 624 from moving further away from the second spring 621. Specifically, the shape of the ratchet block 626 is the structure of the ratchet teeth in the ratchet wheel ratchet structure. When the ratchet block 626 is inserted into the ratchet groove 32, the support rod 61 can be restricted so that it will not be pulled out of the connecting square hole 31.

[0118] In this embodiment, the second limit block 624 always has a tendency to move away from the second spring 621, so that the locking block 625 has a tendency to move upward. During operation, the second limit block 624 is driven close to the second spring 621, so that the locking block 625 moves downward, so that the ratchet block 626 and the ratchet groove 32 are disengaged, and the support rod 61 and the transmission column 30 are unlocked. In this process, the second spring 621 plays an auxiliary role, which provides a pulling force for the first limit block 622.

[0119] In one embodiment, the frame 10 includes a base 11 and a limit seat 12 disposed on the base 11 ; the limit seat 12 is provided with a through limit hole 121 . The limit seat 12 is located below the transmission column 30 .

[0120] The supporting device 60 further includes a push-pull block 63 , a first square sleeve 64 and a second square sleeve 65 .

[0121] The push-pull block 63 is slidably disposed on the frame 10 in a transverse direction, and the upper end of the push-pull block 63 is connected to the support rod 61. The first square sleeve 64 is connected to the lower end of the push-pull block 63, and the center line of the first square sleeve 64 is parallel to the center line of the support rod 61. The second square sleeve 65 is connected to the end of the first square sleeve 64 away from the push-pull block 63, and the end of the second square sleeve 65 away from the first square sleeve 64 is slidably inserted into the limiting hole 121.

[0122] The first square sleeve can be against the limiting seat 12. The two second square sleeves 65 in the two supporting devices 60 are connected by setting a third spring 66. The third spring 66 is located in the limiting hole 121. The third spring 66 applies tension to the two second square sleeves at the same time.

[0123] In this embodiment, under the pulling of the third spring 66, the second square sleeve 65, the first square sleeve 64 and the push-pull block 63 drive the support rod 61 to have a tendency to be inserted into the connecting square hole 31. The third spring 66 can make the push-pull blocks 63 on both sides symmetrical to each other, thereby ensuring that the transmission column 30 on the support rod 61 remains centered relative to the limit seat 12.

[0124] In one embodiment, an end of the third spring 66 is located in the second square sleeve 65 .

[0125] The end of the support rod 61 is provided with a first channel 613, the middle of the push-pull block 63 is provided with a mounting groove 631 facing the other push block, and the upper end of the push-pull block 63 is provided with a second channel 632 communicating with the first channel 613. The second channel 632 is communicated with the upper end of the mounting groove 631, and the lower end of the push-pull block 63 is provided with a third channel 633, and the third channel 633 is communicated with the inner cavity of the first square sleeve 64.

[0126] The supporting device 60 further includes a slider 67 , a connecting rope 68 and an elastic trigger mechanism 69 .

[0127] A slider 67 is slidably disposed in the first square sleeve 64, connected to the end of the third spring 66, and can abut against the end of the second square sleeve 65;

[0128] A connecting rope 68, one end of which is connected to the second limit block 624, and the other end of which is connected to the slider 67 after passing through the first channel 613, the second channel 632, the mounting groove 631 and the third channel 633 in sequence; and

[0129] The elastic trigger mechanism 69 is disposed on the pushing block and is used to apply elastic force to the connecting rope 68 in the installation groove 631 to make it stay away from the bottom of the installation groove 631 .

[0130] In this embodiment, when it is necessary to take out or put in the blood vessel fixing frame 40, the elastic trigger mechanism 69 is driven in reverse, so that the connecting rope 68 is close to the bottom of the installation groove 631, so that part of the connecting rope 68 slides into the second channel 632 and the first channel 613, so that the second limit block 624 slides under the action of the second spring 621, and the locking block 625 moves downward, thereby releasing the lock between the support rod 61 and the transmission column 30. At this time, the push-pull block 63 can be pulled to disengage the support rod 61 from the connecting square hole 31. The blood vessel fixing frame 40 can be put in or taken out.

[0131] After the operation is completed, let go and under the action of the third spring 66, the two second square sleeves 65 approach each other, so that the push-pull block 63 drives the support rod 61 to be inserted into the connecting square hole 31, and the elastic trigger mechanism 69 drives the connecting rope 68 away from the bottom of the installation groove 631, so that the connecting rope 68 is taut, and then the second spring 621 is pulled, the locking block 625 moves up, and the ratchet block 626 is inserted into the corresponding ratchet groove 32, so as to realize the connection and locking of the support rod 61 and the transmission column 30.

[0132] In one embodiment, a mounting hole 634 is defined at the bottom of the mounting slot 631 .

[0133] The elastic trigger mechanism 69 includes a trigger rod 691 and a fourth spring 694 .

[0134] One end of the trigger rod 691 is connected to a stopper 692 , and the other end of the trigger rod 691 passes through the mounting hole 634 and is connected to a handshake 693 . A transition hole 695 that penetrates vertically is formed at one end of the trigger rod 691 away from the stopper 692 .

[0135] The fourth spring 694 is sleeved on the trigger rod 691 , and two ends of the fourth spring 694 are respectively connected to the stopper 692 and the push-pull block 63 . The connecting rope 68 passes through the transition hole 695 .

[0136] In this embodiment, the fourth spring 694 applies a pulling force to the stopper 692, so that the connecting rope 68 in the transition hole 695 of the trigger rod 691 is supported, so that the connecting rope 68 is away from the bottom of the installation groove 631, and the connecting rope 68 is stretched straight. In subsequent operations, the handshake 693 can be pressed to press the connecting rope 68 to the bottom of the installation groove 631.

[0137] In one embodiment, a stop block 696 is connected to the connecting rope 68 , and the stop block 696 can abut against the upper end of the trigger rod 691 .

[0138] During operation, the push-pull block 63 can be directly pulled. At this time, the third spring 66 below is stretched, so that the connecting rope 68 is straightened. Due to the existence of the stop block 696, the connecting rope 68 above the trigger rod 691 will not move down. At this time, the trigger rod 691 is long enough, and the straightened connecting rope 68 drives the trigger rod 691 to retreat, so that the connecting rope 68 above the trigger rod 691 is also relaxed from the straightened state, so that the second spring 621 above drives the guide ring to move, so that the locking block 625 moves downward, and the support rod 61 and the transmission column 30 are unlocked.

[0139] That is, due to the presence of the third spring 66, when placing or removing the vascular fixing frame 40, the support rod 61 on one side can be separated from the transmission column 30 by pulling the push-pull block 63 on one side, while the support rod 61 on the other side remains locked with the transmission column 30.
