Description

Technical Field

[0001] The invention relates to the technical field of detection kit equipment, in particular to a kit for platelet activation detection. Background Art

[0002] Platelets have the function of promoting hemostasis and accelerating coagulation, and play an important role in physiological and pathological processes such as hemostasis, wound healing, inflammatory response, thrombosis, and organ transplant rejection. When the number and quality of platelets are abnormal, it can cause thrombocytopenia and platelet dysfunction. The most direct treatment for these symptoms is platelet transfusion.

[0003] Among them, in the process of inputting the patient's blood into the reagent tube, the damaged blood vessel wall synchronously outputs specific factors, which will cause the specific factors and platelets to enter the inside of the reagent tube synchronously. After the reagent tube is placed in the test kit, and then the test kit is sent to the testing center, if there is a large collision in the external environment, the specific factors will activate the platelets, forcing the shape of the platelets to become dendrites, and at the same time forcing the remaining platelets to change synchronously. The above changes will greatly affect the subsequent platelet activation detection. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a platelet activation detection kit, comprising a shell, four telescopic rods are fixedly connected to the outer wall of the shell, one end of the four telescopic rods away from the shell is fixedly connected to a mounting frame, a pulling spring is fixedly connected to the side wall of the shell, four sliding grooves are opened on the top of the shell, an inclined block is fixedly connected to the side wall of the mounting frame, a sliding plate is slidably connected to the side wall of the shell, a limiting component is fixedly connected to the side wall of the shell, and a buffer component is slidably connected to the outer wall of the shell;

[0005] The hydraulic mechanism includes a piston block slidably connected to the inner walls of the four slide grooves, a fixed frame is fixedly connected to the top of the piston block, a roller is rotatably connected to the inner wall of the fixed frame, a spring telescopic rod is fixedly connected to the top of the piston block, the other end of the spring telescopic rod is fixedly connected to a contact block, a closing plate is rotatably connected to one end of the contact block near the slide plate, and a buckle switch is fixedly connected to the side wall of the closing plate;

[0006] The clamping assembly includes a transmission tube fixedly connected to the inner wall of the through hole of the slide, the other end of the transmission tube is connected to the water storage tank, and the side wall of the water storage tank is fixedly connected to an expansion bag. In order to solve the problem that the liquid inside the reagent tube will fluctuate violently under the action of the reaction when the reagent kit is hit, a hydraulic mechanism and a clamping assembly are arranged inside the equipment. Before use, the staff puts the test tube between several expansion bags, which are presented as follows Figure 4The equipment is in the middle G state, and then the staff closes the closing plate and presses the closing plate downward. After the buckle switch is locked, the equipment is in the protection state. When the closing plate contacts the outer wall of the contact block, the downward pressure of the closing plate is transmitted to the piston block through the spring telescopic rod fixing frame, forcing the piston block to slide downward along the inner wall of the slide slot, so that the liquid inside the slide slot is transmitted to the water storage tank through the transmission pipe. The increase in liquid inside the water storage tank will force the expansion bag to expand, and multiple expanded expansion bags will squeeze and clamp the reagent tube; when the equipment collides with the external environment, the force generated by the outside contacts the mounting frame, and while forcing the equipment to deviate, the mounting frame presses the telescopic rod and contracts, and the mounting frame drives the inclined surface of the inclined surface block to contact the outer wall of the roller, presenting as shown Figure 5 The state shown in the figure, the inclined surface of the inclined surface block will push the roller and the fixed frame to move upward, and the fixed frame will drive the piston block to slide upward along the slide groove, forcing the expansion bag of the impacted surface to shrink. While the expansion bag of the impacted surface shrinks, the remaining expansion bags will expand again under the push of the corresponding spring telescopic rods. Through the application of the above components, when the device collides, the expansion bags in the same direction shrink, and the remaining expansion bags expand. When the reagent tube is subjected to the reaction force of the impact, the reagent tube will be forced to generate a force opposite to the reaction force. The above force offsets most of the reaction force, thereby reducing the amplitude change of the blood in the reagent tube after the reagent tube is impacted.

[0007] Preferably, the buffer assembly comprises a sliding plate slidably connected to the outer wall of the contact arc plate, and the side wall of the sliding plate is fixedly connected to the air pressure box.

[0008] Preferably, the buffer assembly also includes a piston plate slidably connected to the inner wall of the air pressure box, a push rod is fixedly connected to the top of the piston plate, and two exhaust ports are opened on the top of the piston plate.

[0009] Preferably, the buffer assembly also includes a compression block slidably connected to the inner wall of the shell, a return spring is fixedly connected to the bottom of the piston plate, one end of the return spring away from the piston plate is fixedly connected to the inner wall of the air pressure box, four water storage tank inner walls are fixedly connected with sealing blocks, the inner wall of the through hole of the sealing block is slidably connected with a cross slide, the inner wall of the cross slide is fixedly connected with a transmission pipe, and the top of the transmission pipe is through-connected with an air bag. By utilizing the characteristics that the above components are mostly arranged at the bottom of the shell, the overall device is guaranteed to be in a state of being top-light and feet-heavy. When the device falls to the ground due to a collision, due to the heavy weight of the device, the heavier end will always face the ground during the falling process of the device, and a buffer assembly is arranged at this end. At the moment when the sliding plate contacts the ground, The sliding plate will slide along the outer wall of the shell, and the sliding plate will slide upward along the outer wall of the piston plate through the air pressure box. In this process, the air inside the air pressure box will be squeezed and ejected outward through the exhaust port. However, due to the small holes in the exhaust port, it is difficult for the air inside the air pressure box to be emptied outward at one time, resulting in a certain resistance when the air pressure box slides along the outer wall of the piston plate. After the buffering is completed, the reset spring releases the mechanical power, but due to the small diameter of the exhaust port, the speed at which the external air enters the air pressure box is slow. Through the application of the above-mentioned components, the buffering effect of the spring is replaced, so that after the piston plate completes the buffering, there will be no rebound phenomenon, which avoids the rebound causing the liquid on the inner wall of the reagent tube to shake and cause secondary damage to the liquid.

[0010] Preferably, the limiting component includes a contact arc plate fixedly connected to the top of the sliding plate, a pulling belt fixedly connected to the side wall of the closing plate, and the end of the pulling belt away from the closing plate is fixedly connected to the side wall of the sliding plate. Taking advantage of the fact that the heavier end of the above-mentioned device is in contact with the ground, a compression block is arranged inside the device. When the sliding plate contacts the ground and provides a buffer space for the device, the compression block contacts the ground and forces the compression block to slide upward along the inner wall of the outer shell, and the compression block will squeeze the sealed space at the bottom of the water tank, so that the gas in the above space is transmitted to the airbag through the transmission pipe, forcing the airbag to expand, and the expanded airbag will contact the bottom of the reagent tube. Through the application of the above-mentioned components, the device can lift the bottom of the reagent tube after falling downward, so as to avoid hard contact between the bottom of the reagent tube and the device, causing the reagent tube to rupture.

[0011] Preferably, the limiting assembly further comprises a gear rod 1 fixedly connected to the side wall of the slide plate, a gear rod 2 is slidably connected to the side wall of the shell, and a gear is rotatably connected to the side wall of the shell.

[0012] Preferably, the outer wall of the first gear rod is meshedly connected with the outer wall of the gear, and the outer wall of the gear is meshedly connected with the outer wall of the second gear rod, and the end of the pulling spring away from the housing is connected to the mounting bracket.

[0013] Preferably, the limiting component also includes a linkage rod fixedly connected to the bottom of the second gear rod, and the end of the linkage rod away from the second gear rod is fixedly connected to a limiting block. After the transportation is completed, when the staff opens the equipment through the snap switch, the multiple spring telescopic rods will release the accumulated mechanical power, forcing the closing plate to move upward, and the pressure on the expansion bag disappears, forcing the liquid inside the expansion bag to return to the inside of the slide groove through the transmission tube, and the piston block moves upward. During the resetting of the component, the closing plate drives the slide plate to move upward by pulling the belt. At the same time, the slide plate forces the second gear rod and the linkage rod to move downward through the gear. The linkage rod drives the limiting block to move downward and contact the outer wall of the contact arc plate. The contact arc plate drives the sliding plate to move downward along the outer shell, so that the sliding plate unfolds downward, and the sliding plate drives multiple piston plates to reset. Through the application of the above-mentioned components, after the equipment is opened, the sliding plate can ensure the stability of the equipment base, to avoid the sliding plate sliding due to pressure when the staff fills the reagent tube, affecting the stability of the equipment during filling.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention aims to solve the problem that when the reagent box is hit, the liquid inside the reagent tube will fluctuate violently under the reaction. A hydraulic mechanism and a clamping assembly are arranged inside the device. Before use, the staff puts the test tube between several expansion bags, which are presented as follows. Figure 4 The equipment is in the middle G state, and then the staff closes the closing plate and presses the closing plate downward. After the buckle switch is locked, the equipment is in the protection state. When the closing plate contacts the outer wall of the contact block, the downward pressure of the closing plate is transmitted to the piston block through the spring telescopic rod fixing frame, forcing the piston block to slide downward along the inner wall of the slide slot, so that the liquid inside the slide slot is transmitted to the water storage tank through the transmission pipe. The increase in liquid inside the water storage tank will force the expansion bag to expand, and multiple expanded expansion bags will squeeze and clamp the reagent tube; when the equipment collides with the external environment, the force generated by the outside contacts the mounting frame, and while forcing the equipment to deviate, the mounting frame presses the telescopic rod and contracts, and the mounting frame drives the inclined surface of the inclined surface block to contact the outer wall of the roller, presenting as shown Figure 5 The state shown in the figure, the inclined surface of the inclined surface block will push the roller and the fixed frame to move upward, and the fixed frame will drive the piston block to slide upward along the slide groove, forcing the expansion bag of the impacted surface to shrink. While the expansion bag of the impacted surface shrinks, the remaining expansion bags will expand again under the push of the corresponding spring telescopic rods. Through the application of the above components, when the device collides, the expansion bags in the same direction shrink, and the remaining expansion bags expand. When the reagent tube is subjected to the reaction force of the impact, the reagent tube will be forced to generate a force opposite to the reaction force. The above force offsets most of the reaction force, thereby reducing the amplitude change of the blood in the reagent tube after the reagent tube is impacted.

[0016] (2) The present invention utilizes the characteristic that the above-mentioned components are mostly arranged at the bottom of the shell to ensure that the device as a whole is in a state of being top-light with the feet heavy. When the device falls to the ground due to a collision, due to the heavy mass of the device, the heavier end will always face the ground during the falling process of the device, and a buffer component is arranged at this end. At the moment when the sliding plate contacts the ground, the sliding plate will slide along the outer wall of the shell, and the sliding plate will slide upward along the outer wall of the piston plate through the air pressure box. During this process, the air inside the air pressure box will be squeezed and will be ejected outward through the exhaust port. However, due to the small hole of the exhaust port, the air inside the air pressure box is difficult to be emptied outward at one time, resulting in a certain resistance when the air pressure box slides along the outer wall of the piston plate. After the buffering is completed, the reset spring releases the mechanical power, but due to the small diameter of the exhaust port, the speed at which the external air enters the air pressure box is slow. Through the application of the above-mentioned components, the buffering effect of the spring is replaced, so that after the piston plate completes the buffering, there will be no rebound phenomenon, which avoids the rebound causing the liquid on the inner wall of the reagent tube to shake and cause secondary damage to the liquid.

[0017] (3) The present invention utilizes the characteristic that the heavier end of the above-mentioned device is in contact with the ground, and a compression block is arranged inside the device. When the sliding plate contacts the ground and provides a buffer space for the device, the compression block contacts the ground and forces the compression block to slide upward along the inner wall of the outer shell, and the compression block squeezes the sealed space at the bottom of the water tank, so that the gas in the above space is transmitted to the airbag through the transmission pipe, forcing the airbag to expand, and the expanded airbag will contact the bottom of the reagent tube. Through the application of the above-mentioned components, the device can lift the bottom of the reagent tube after falling downward, so as to avoid hard contact between the bottom of the reagent tube and the device, causing the reagent tube to rupture.

[0018] (4) After the transportation of the present invention is completed, when the staff opens the equipment through the snap switch, multiple spring telescopic rods will release the accumulated mechanical power, forcing the closing plate to move upward, and the pressure on the expansion bag disappears, forcing the liquid inside the expansion bag to return to the inside of the slide groove through the transmission tube, and the piston block moves upward. During the reset process of the component, the closing plate drives the slide plate to move upward by pulling the belt. At the same time, the slide plate forces the gear rod 2 and the linkage rod to move downward through the gear. The linkage rod drives the limiting block to move downward and contact the outer wall of the contact arc plate. The contact arc plate drives the sliding plate to move downward along the outer shell, so that the sliding plate unfolds downward, and the sliding plate drives multiple piston plates to reset. Through the application of the above-mentioned components, after the equipment is opened, the sliding plate can ensure the stability of the base of the equipment, so as to avoid the sliding of the sliding plate due to pressure when the staff is filling the reagent tube, thereby affecting the stability of the equipment during filling.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] For example, see Figure 1 - Figure 5 The present invention is a platelet activation detection kit, comprising a shell 1, four telescopic rods 11 are fixedly connected to the outer wall of the shell 1, a mounting frame 14 is fixedly connected to the end of the four telescopic rods 11 away from the shell 1, a pulling spring 12 is fixedly connected to the side wall of the shell 1, four sliding grooves 13 are opened on the top of the shell 1, a slope block 15 is fixedly connected to the side wall of the mounting frame 14, a slide plate 16 is slidably connected to the side wall of the shell 1, a limiting component 5 is fixedly connected to the side wall of the shell 1, and a buffer component 4 is slidably connected to the outer wall of the shell 1;

[0034] The hydraulic mechanism 2 includes a piston block 21 slidably connected to the inner walls of the four slide grooves 13, a fixing frame 22 is fixedly connected to the top of the piston block 21, a roller 23 is rotatably connected to the inner wall of the fixing frame 22, a spring telescopic rod 24 is fixedly connected to the top of the piston block 21, the other end of the spring telescopic rod 24 is fixedly connected to a contact block 25, one end of the contact block 25 close to the slide plate 16 is rotatably connected to a closing plate 26, and a buckle switch 27 is fixedly connected to the side wall of the closing plate 26;

[0035] The clamping assembly 3 includes a transmission tube 31 fixedly connected to the inner wall of the through hole of the slide 13, and the other end of the transmission tube 31 is connected to the water storage tank 32. The side wall of the water storage tank 32 is fixedly connected to the expansion bag 33. In order to solve the problem that the liquid inside the reagent tube will fluctuate violently under the action of the reaction when the reagent box is hit, a hydraulic mechanism 2 and a clamping assembly 3 are arranged inside the equipment. Before use, the staff puts the test tube between several expansion bags 33, which are as shown in the figure. Figure 4 The device is in the middle G state, and then the staff closes the closing plate 26 and presses the closing plate 26 downward. After the buckle switch 27 is locked, the device is in the protection state. When the closing plate 26 contacts the outer wall of the contact block 25, the downward pressure of the closing plate 26 is transmitted to the piston block 21 through the spring telescopic rod 24 fixing frame 22, forcing the piston block 21 to slide downward along the inner wall of the slide groove 13, so that the liquid inside the slide groove 13 is transmitted to the water storage tank 32 through the transmission pipe 31. The increase in liquid inside the water storage tank 32 will force the expansion bag 33 to expand, and the multiple expanded expansion bags 33 will squeeze and clamp the reagent tube; when the device collides with the external environment, the force generated by the outside contacts the mounting frame 14, and while forcing the device to deviate, the mounting frame 14 presses the telescopic rod 11 and contracts, and the mounting frame 14 drives the inclined surface of the inclined surface block 15 to contact the outer wall of the roller 23, presenting as shown Figure 5 In the state shown, the inclined surface of the inclined plane block 15 will push the roller 23 and the fixing frame 22 to move upward, and the fixing frame 22 drives the piston block 21 to slide upward along the slide groove 13, forcing the expansion bag 33 of the impacted surface to shrink. When the expansion bag 33 of the impacted surface shrinks, the remaining expansion bags 33 will expand again under the push of the corresponding spring telescopic rod 24. Through the application of the above-mentioned components, when the device collides, the expansion bags 33 in the same direction shrink, and the remaining expansion bags 33 expand. When the reagent tube is subjected to the reaction force of the impact, the reagent tube will be forced to generate a force opposite to the reaction force, and the above force will offset most of the reaction force, thereby reducing the amplitude change of the blood in the reagent tube after the reagent tube is impacted.

[0036] For example 2, please refer to Figure 6 - Fig.10 The present invention is a platelet activation detection kit. Based on the first embodiment, the buffer component 4 includes a sliding plate 41 slidably connected to the outer wall of the contact arc plate 51, and a pressure box 42 is fixedly connected to the side wall of the sliding plate 41.

[0037] The buffer assembly 4 further comprises a piston plate 43 slidably connected to the inner wall of the air pressure box 42 , a push rod 45 is fixedly connected to the top of the piston plate 43 , and two exhaust ports 44 are provided on the top of the piston plate 43 .

[0038] The buffer assembly 4 also includes a compression block 46 slidably connected to the inner wall of the outer shell 1, a return spring 47 is fixedly connected to the bottom of the piston plate 43, and the end of the return spring 47 away from the piston plate 43 is fixedly connected to the inner wall of the air pressure box 42, and the inner walls of the four water storage tanks 32 are fixedly connected with sealing blocks 411, and the inner wall of the through hole of the sealing block 411 is slidably connected with a cross slide 48, and the inner wall of the cross slide 48 is fixedly connected with a transmission pipe 31, and the top of the transmission pipe 31 is through-connected with an air bag 410. By utilizing the characteristics that the above-mentioned components are mostly arranged at the bottom of the outer shell 1, it is ensured that the overall equipment is in a state of being top-light and feet-heavy. When the equipment falls to the ground due to a collision, due to the heavy mass of the equipment, the heavier end will always face the ground during the falling process of the equipment, and a buffer assembly 4 is arranged at this end. At the moment when the sliding plate 41 contacts the ground During this time, the sliding plate 41 will slide along the outer wall of the shell 1, and the sliding plate 41 will slide upward along the outer wall of the piston plate 43 through the air pressure box 42. In this process, the air inside the air pressure box 42 will be squeezed and ejected outward through the exhaust port 44, but limited by the small hole of the exhaust port 44, the air inside the air pressure box 42 is difficult to be emptied outward at one time, resulting in a certain resistance when the air pressure box 42 slides along the outer wall of the piston plate 43. After the buffering is completed, the reset spring 47 releases the mechanical power, but due to the small diameter of the exhaust port 44, the speed at which the external air enters the air pressure box 42 is slow. Through the application of the above-mentioned components, the buffering effect of the spring is replaced, so that after the piston plate 43 completes the buffering, there will be no rebound phenomenon, which avoids the rebound causing the liquid on the inner wall of the reagent tube to shake and cause secondary damage to the liquid.

[0039] The limiting component 5 includes a contact arc plate 51 fixedly connected to the top of the sliding plate 41, and a pulling belt 52 is fixedly connected to the side wall of the closing plate 26. The end of the pulling belt 52 away from the closing plate 26 is fixedly connected to the side wall of the slide plate 16. Taking advantage of the fact that the heavier end of the above-mentioned device is in contact with the ground, a compression block 46 is arranged inside the device. When the sliding plate 41 contacts the ground and provides a buffer space for the device, the compression block 46 contacts the ground and forces the compression block 46 to slide upward along the inner wall of the outer shell 1, and the compression block 46 will squeeze the sealed space at the bottom of the water tank 32, so that the gas in the above space is transmitted to the airbag 410 through the transmission pipe 31, forcing the airbag 410 to expand, and the expanded airbag 410 will contact the bottom of the reagent tube. Through the application of the above-mentioned components, the device can lift the bottom of the reagent tube after falling down to avoid hard contact between the bottom of the reagent tube and the device, causing the reagent tube to rupture.

[0040] The limiting assembly 5 further comprises a gear rod 1 54 fixedly connected to the side wall of the slide plate 16 , a gear rod 2 56 slidably connected to the side wall of the housing 1 , and a gear 55 rotatably connected to the side wall of the housing 1 .

[0041] The outer wall of the gear rod 1 54 is meshed with the outer wall of the gear 55 , and the outer wall of the gear 55 is meshed with the outer wall of the gear rod 2 56 , pulling the end of the spring 12 away from the housing 1 and the mounting bracket 14 .

[0042] The limiting assembly 5 also includes a linkage rod 57 fixedly connected to the bottom of the second gear rod 56. The end of the linkage rod 57 away from the second gear rod 56 is fixedly connected to a limiting block 58. After the transportation is completed, when the staff opens the equipment through the buckle switch 27, the multiple spring telescopic rods 24 will release the accumulated mechanical power, forcing the closing plate 26 to move upward, and the pressure on the expansion bag 33 disappears, forcing the liquid inside the expansion bag 33 to return to the inside of the chute 13 through the transmission pipe 31, and the piston block 21 moves upward. In the process of resetting the assembly, the closing plate 26 drives the slide plate 16 to move upward by pulling the belt 52. The sliding plate 41 moves downward along the outer shell 1, so that the sliding plate 41 is unfolded downward, and the sliding plate 41 drives the multiple piston plates 43 to reset. Through the application of the above components, after the equipment is opened, the sliding plate 41 can ensure the stability of the base of the equipment, so as to avoid the sliding plate 41 sliding due to pressure when the staff is filling the reagent tube, thereby affecting the stability of the equipment during filling.

[0043] A specific application of this embodiment is: before use, the staff puts the test tube between several expansion bags 33, presenting as follows Figure 4 The device is in the middle G state, and then the staff closes the closing plate 26 and presses the closing plate 26 downward. After the buckle switch 27 is locked, the device is in the protection state. When the closing plate 26 contacts the outer wall of the contact block 25, the downward pressure of the closing plate 26 is transmitted to the piston block 21 through the spring telescopic rod 24 fixing frame 22, forcing the piston block 21 to slide downward along the inner wall of the slide groove 13, so that the liquid inside the slide groove 13 is transmitted to the water storage tank 32 through the transmission pipe 31. The increase in liquid inside the water storage tank 32 will force the expansion bag 33 to expand, and the multiple expanded expansion bags 33 will squeeze and clamp the reagent tube; when the device collides with the external environment, the force generated by the outside contacts the mounting frame 14, and while forcing the device to deviate, the mounting frame 14 presses the telescopic rod 11 and contracts, and the mounting frame 14 drives the inclined surface of the inclined surface block 15 to contact the outer wall of the roller 23, presenting as shown Figure 5In the state shown, the inclined surface of the inclined plane block 15 will push the roller 23 and the fixing frame 22 to move upward, and the fixing frame 22 drives the piston block 21 to slide upward along the slide groove 13, forcing the expansion bag 33 of the impacted surface to shrink. When the expansion bag 33 of the impacted surface shrinks, the remaining expansion bags 33 will expand again under the push of the corresponding spring telescopic rod 24. Through the application of the above-mentioned components, when the device collides, the expansion bags 33 in the same direction shrink, and the remaining expansion bags 33 expand. When the reagent tube is subjected to the reaction force of the impact, the reagent tube will be forced to generate a force opposite to the reaction force, and the above force will offset most of the reaction force, thereby reducing the amplitude change of the blood in the reagent tube after the reagent tube is impacted.

[0044] By utilizing the characteristic that most of the above-mentioned components are arranged at the bottom of the shell 1, the device as a whole is ensured to be in a state of being top-light with the feet being heavy. When the device falls to the ground due to a collision, due to the heavy mass of the device, the heavier end will always face the ground during the falling process of the device, and a buffer component 4 is arranged at this end. At the moment when the sliding plate 41 contacts the ground, the sliding plate 41 will slide along the outer wall of the shell 1, and the sliding plate 41 slides upward along the outer wall of the piston plate 43 through the air pressure box 42. During this process, the air inside the air pressure box 42 will be squeezed and ejected outward through the exhaust port 44. However, due to the small hole of the exhaust port 44, the air inside the air pressure box 42 is difficult to be emptied outward at one time, resulting in a certain resistance when the air pressure box 42 slides along the outer wall of the piston plate 43. After the buffering is completed, the return spring 47 releases the mechanical power, but due to the small diameter of the exhaust port 44, the speed at which the external air enters the air pressure box 42 is relatively low. Slow, through the application of the above-mentioned components, the buffering effect of the spring is replaced, so that after the piston plate 43 completes the buffering, there will be no rebound phenomenon, so as to avoid the rebound causing the liquid on the inner wall of the reagent tube to shake, causing secondary damage to the liquid. Taking advantage of the fact that the heavier end of the above-mentioned equipment is in contact with the ground, a compression block 46 is arranged inside the equipment. When the sliding plate 41 contacts the ground and provides a buffer space for the equipment, the compression block 46 contacts the ground and forces the compression block 46 to slide upward along the inner wall of the outer shell 1, and the compression block 46 will squeeze the sealed space at the bottom of the water tank 32, so that the gas in the above space is transmitted to the airbag 410 through the transmission pipe 31, forcing the airbag 410 to expand, and the expanded airbag 410 will contact the bottom of the reagent tube. Through the application of the above-mentioned components, the equipment can lift the bottom of the reagent tube after falling down, so as to avoid hard contact between the bottom of the reagent tube and the equipment, causing the reagent tube to rupture.

[0045] After the transportation is completed, when the staff opens the equipment through the snap switch 27, the multiple spring telescopic rods 24 will release the accumulated mechanical power, forcing the closing plate 26 to move upward, and the pressure on the expansion bag 33 disappears, forcing the liquid inside the expansion bag 33 to return to the inside of the slide groove 13 through the transmission tube 31, and the piston block 21 moves upward. During the reset of the component, the closing plate 26 drives the slide plate 16 to move upward by pulling the belt 52. At the same time, the slide plate 16 forces the gear rod 2 56 and the linkage rod 57 to move downward through the gear 55. The linkage rod 57 drives the limiting block 58 to move downward and contacts the outer wall of the contact arc plate 51. The contact arc plate 51 drives the sliding plate 41 to move downward along the outer shell 1, so that the sliding plate 41 unfolds downward, and the sliding plate 41 drives multiple piston plates 43 to reset. Through the application of the above-mentioned components, after the equipment is opened, the sliding plate 41 can ensure the stability of the equipment base, so as to avoid the sliding of the sliding plate 41 due to pressure when the staff is filling the reagent tube, thereby affecting the stability of the equipment during filling.
