Description

Technical Field

[0001] The present invention relates to the field of thrombus detection, in particular to a thrombus detector. Background Art

[0002] A thrombus detector is a medical device used to detect and analyze thrombosis. This device plays an important role in medical diagnosis, helping doctors understand the patient's thrombosis condition and thus provide targeted treatment. The working principle of a thrombus detector is mainly based on centrifugal technology. During the detection process, the instrument simulates the temperature and blood circulation speed in the human body, and gathers the thrombosis factors in the blood sample through centrifugation. By observing and analyzing parameters such as the length, dry weight and wet weight of the formed thrombus, doctors can determine the degree and type of thrombosis.

[0003] When using a thrombus detector, you first need to prepare a clean plastic tube and syringe, and take venous blood as a sample. Then, inject the blood sample into a plastic ring, connect it into a ring, put it on the plexiglass, and place it on the turntable of the instrument. After starting the instrument, the motor starts to rotate and the spotlight lights up for easy observation. As the turntable rotates, a thrombus gradually forms. The instrument will automatically alarm after a set time, indicating that the test is complete. At this time, you can remove the plexiglass ring to observe and analyze the shape and size of the thrombus.

[0004] From the operation of the above-mentioned thrombus detector, it can be seen that the blood sample needs to be injected into a plastic tube and then centrifuged, but the pouring time of different samples in the same batch will affect the thrombus detection. Too long pouring time may cause the thrombus to disperse or deform, while too short pouring time may cause the thrombus to fail to form or fix completely. In addition, the thrombus is generally poured out manually or with tools, and it is difficult to control the pouring rhythm of the thrombus, which may adversely affect the accuracy of thrombus detection.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] All the items mentioned in the present invention can be obtained in the market or through private ordering.

[0031] A thrombus detector, such as Figure 1-10 As shown, it includes a fixed shell 1, and a centrifugal mechanism is installed inside the fixed shell 1. The centrifugal mechanism includes a motor 12. The motor 12 is installed on a mounting frame 13 inside the fixed shell 1. The output shaft of the motor 12 is connected to a mounting disk 10. The mounting disk 10 is in a boss shape. The mounting disk 10 and the output shaft of the motor 12 are connected by a snap mechanism 11. The snap mechanism 11 includes a button 27. The button 27 is movably arranged on the top of the mounting disk 10. One end of the button 27 is rotatably connected to a connecting rod 28. One end of the connecting rod 28 is rotatably connected to an insert block 29. A reset spring 30 is arranged at the bottom end of the button 27. The mounting disk 10 and the output shaft of the motor 12 are connected by a fixed spring 31. The artificial blood vessel placement ring is arranged on the top of the mounting disk 10.

[0032] That is, when the mounting disk 10 needs to be ejected from the output shaft of the motor 12, the button 27 is pressed downward so that the button 27 squeezes the reset spring 30 until the connecting rod 28 drives the insert block 29 to disengage from the slot. At this time, the fixation is released, and the fixing spring 31 ejects the mounting disk 10. When the mounting disk 10 needs to be reset, the mounting disk 10 is squeezed downward until the insert block 29 is reinserted into the slot to achieve the reset of the mounting disk 10.

[0033] The artificial blood vessel placement ring is composed of a plurality of connection blocks 4, which are rotatably connected by a rotating shaft, and the head and tail connection blocks 4 are connected to each other by a mounting mechanism, and the mounting mechanism includes a sliding block 6, and a limit block 7 is slidably arranged in the groove on the head end connection block 4 of the artificial blood vessel placement ring, and the limit block 7 is connected to the groove by a first spring 8, and a sliding block 6 is slidably arranged in the groove of the tail end connection block 4 of the artificial blood vessel placement ring, and the sliding block 6 can be inserted into the groove of the tail end connection block 4 and matched with the limit block 7;

[0034] When it is necessary to connect the ends of the artificial blood vessel placement ring, insert the sliding block 6 into the groove inside the tail end connecting block 4 and cooperate with the limit block 7. One end of the limit block 7 is arc-shaped, and the surface of the sliding block 6 is provided with a slot that cooperates with the arc of one end of the limit block 7. After the sliding block 6 is inserted into the limit block 7, the first spring 8 will be squeezed until the limit block 7 is inserted into the slot, thereby realizing the end-to-end connection of the artificial blood vessel placement ring. After the end-to-end connection is completed, the artificial blood vessel can be placed in the mounting groove 5 on the surface of the connecting block 4. At this time, the artificial blood vessel placement ring is placed in the centrifugal mechanism for centrifugal work.

[0035] Furthermore, the mounting mechanism can effectively prevent the artificial blood vessel placement ring from detaching when it is placed on the centrifugal mechanism for centrifugal work. When centrifuging, under the action of centrifugal force, the limit block 7 will be inserted into the slot in the sliding block 6, making it tighter, so that unlocking will not occur, and the tightening effect is better.

[0036] After the centrifugation is completed, the sealing cover 22 disposed on the top surface of the fixed shell 1 can be opened, the artificial blood vessel placement ring inside can be taken out, and the sliding block 6 can be pulled to one side to separate the sliding block 6 from the squeezing of the limiting block 7, thereby realizing the separation of the head and tail connecting blocks 4;

[0037] At this time, the unfolded artificial blood vessel placement ring can be placed in a detection mechanism for detection. The detection mechanism includes a protective shell 15, which is slidably connected to the surface track of the fixed shell 1. The top of the protective shell 15 is rotatably connected to the placement table 2 through a rotating shaft. A plurality of clamping blocks 3 are fixedly arranged on the top of the placement table 2. The clamping blocks 3 can be inserted into the gaps between the connecting blocks 4, so that the artificial blood vessel placement ring can be fixed on the placement table 2. Then, the placement table 2 is rotated upward along the rotating shaft and supported by the support rod 14 arranged between the placement table 2 and the protective shell 15. At this time, the obliquely arranged placement table 2 will make one end of the artificial blood vessel contact the test paper 26 under the protective shell 15, and then prepare for the subsequent thrombus discharge work;

[0038] After the artificial blood vessel placement ring is installed, the protective shell 15 is pulled to one side. The protective shell 15 will drive the placement table 2 to move synchronously during the movement, and an auxiliary experimental mechanism is installed inside the protective shell 15 to discharge the thrombus in the artificial blood vessel.

[0039] The auxiliary experimental mechanism includes a gas generating mechanism, the gas outlet of the gas generating mechanism is connected to a hose 16, one end of the hose 16 is connected to a positioning shell 23, one side of the positioning shell 23 is slidably connected to a connecting pipe 24, one end of the connecting pipe 24 is connected to an outlet pipe 20 on the surface of the fixed block 19, and a second spring 25 is connected between the fixed block 19 and the positioning shell 23. The gas generated by the gas generating mechanism will enter the positioning shell 23 through the hose 16 and be discharged by the connecting pipe 24. Since the connecting pipe 24 and the positioning shell 23 are slidably connected and the two are slidably sealed, when installing the artificial blood vessel placement ring, the fixed block 19 can be pulled to one side, and under the action of the second spring 25, the outlet pipe 20 on the surface of the fixed block 19 is connected to the artificial blood vessel.

[0040] Therefore, after the gas generating mechanism generates gas, the gas will enter the positioning shell 23 through the hose 16, and be discharged through the connecting tube 24, and then enter the outlet pipe 20 and be sprayed out. Since the outlet pipe 20 is connected to the artificial blood vessel, the gas will push the thrombus in the artificial blood vessel to be discharged onto the test paper 26.

[0041] The gas generating mechanism includes an air pump 17 and a gear set mechanism 18. The air pump 17 is installed inside the protective shell 15. The gear set mechanism 18 is installed on the top of the air pump 17. The gear set mechanism 18 is connected to the impeller inside the air pump 17. The fixed shell 1 is adapted to be arranged in the surface track of the sliding of the protective shell 15, and a rack matching the gear set mechanism 18 is arranged. A part of a gear of the gear set mechanism 18 is located outside the protective shell 15, and the gear is meshed with the rack. When the protective shell 15 slides, the gear and rack are meshed with each other to drive the gear set mechanism 18 to operate. Therefore, when the protective shell 15 moves forward, the gear of the gear set mechanism 18 located outside the protective shell 15 will mesh and rotate with the rack, thereby driving the overall gear set mechanism 18 to operate, so that the air pump 17 works and gas is filled into the hose 16 to facilitate subsequent thrombus discharge.

[0042] A connecting groove 9 is provided inside the mounting groove 5 of the connecting block 4 at the tail end of the artificial blood vessel placement ring. The shape and size of the connecting groove 9 match the air outlet pipe 20. After the artificial blood vessel placement ring is fixed on the placement table 2, the fixing block 19 is pulled to one side, and under the action of the second spring 25, the air outlet pipe 20 on the surface of the fixing block 19 is connected to the artificial blood vessel. The position of the air outlet pipe 20 at this time is the connecting groove 9, which plays a positioning role.

[0043] Furthermore, the artificial blood vessel is placed in the mounting groove 5 on the surface of the connection block 4. When the artificial blood vessel placement ring is not connected end to end, one end of the artificial blood vessel is located outside the connection block 4, and the other end is received inside the connection block 4. Therefore, after the end to end connection, the end of the artificial blood vessel located outside can be just inserted into the connection block 4 at the other end, and contact and seal with the end of the artificial blood vessel inside the connection block 4, so that the two ends of the artificial blood vessel are sealed;

[0044] At the same time, since one end of the artificial blood vessel in the unfolded state extends out of the connecting block 4, when it is installed on the placement table 2, when the placement table 2 is tilted upward, the artificial blood vessel just contacts the surface of the test paper 26, making it easier to discharge the thrombus.

[0045] The surface of the fixed shell 1 is slidably provided with a ruler 21 on one side of the auxiliary experimental mechanism. When the auxiliary experimental mechanism pulls to one side and pushes out the thrombus inside the artificial blood vessel, since the thrombus may not be pushed out directly from the starting position, the position of the ruler 21 can be adjusted to facilitate the subsequent determination of the thrombus length.

[0046] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
