Description

Technical Field

[0001] This utility model belongs to the field of medical testing equipment technology, and in particular relates to an erythrocyte sedimentation rate (ESR) testing stand. Background Technology

[0002] Erythrocyte sedimentation rate (ESR) is an important indicator for monitoring inflammatory responses and diseases in clinical medicine. Its detection principle is to assess the pathological state by observing the sedimentation rate of red blood cells in plasma after anticoagulated blood has been left to stand.

[0003] Chinese utility model patent CN204044031U discloses an automated erythrocyte sedimentation rate (ESR) detection device. This device mainly consists of an L-shaped, integrated base and a main frame. Its technical features include: an array of arc-shaped grooves with downward-extending structures on the front of the main frame, with the bottom of the grooves extending to the base's operating panel to form a positioning slot approximately 1 cm deep; a matching timer module and indicator light system integrated inside the main frame; and a rechargeable lithium battery power supply system. Although this device simplifies the operation process through its mechanical positioning structure, it suffers from the following technical defects in practical applications: the groove positioning system lacks a vertical calibration mechanism, easily causing tilt angle deviations after test tube insertion, affecting the erythrocyte sedimentation trajectory. To address these defects, we propose an ESR detection frame. Utility Model Content

[0004] The purpose of this utility model is to provide a erythrocyte sedimentation rate (ESR) testing frame to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A erythrocyte sedimentation rate (ESR) testing frame, comprising:

[0006] Erythrocyte sedimentation rate (ESR) tube, which consists of a transparent test tube and a detachable rubber cap mounted on the top of the transparent test tube;

[0007] A rotating base includes a horizontally arranged cylindrical support base. A circular groove is formed at the center of the upper surface of the support base. A turntable is rotatably mounted in the groove via a bearing. A drive assembly for driving the turntable to rotate is provided inside the support base.

[0008] A erythrocyte sedimentation rate (ESR) observation frame includes an assembly plate coaxially mounted with a turntable. A cylindrical test tube limiting block is coaxially fixed at the upper center of the assembly plate. Multiple vertically extending test tube clearance grooves are arranged in a circular array on the circumferential sidewall of the test tube limiting block. A test tube insertion groove corresponding to the position of the test tube clearance groove is opened along the circumferential direction on the upper surface of the assembly plate. An elastic clamping component is provided at the upper end of the test tube limiting block. A scale marking line extending along the axial direction is provided on the outer surface of the test tube limiting block.

[0009] An assembly structure is provided between the bottom surface of the assembly plate and the upper surface of the turntable, which is used to achieve axial positioning assembly of the erythrocyte sedimentation rate observation frame and the rotating base.

[0010] The flatness adjustment structure includes three height adjustment legs arranged in an equilateral triangle on the bottom surface of the support base, and a level calibrator set on the upper surface of the turntable.

[0011] Preferably, the elastic clamping assembly includes a support plate fixed to the upper surface of the test tube limiting block by a column. The support plate has multiple through holes arranged in a circumferential array. A pull rod slides through each through hole. The upper end of the pull rod is fixed to the limiting plate, and the lower end passes through the through hole and is fixedly connected to a clamping cylinder. A tension spring is sleeved on the pull rod, with its two ends fixedly connected to the limiting plate and the support plate, respectively.

[0012] Preferably, the assembly structure includes four cylindrical positioning pins that are vertically fixed in a circumferential array on the upper surface of the turntable, and four positioning holes correspondingly opened on the bottom surface of the assembly plate. A permanent magnet is embedded in the bottom of the positioning hole, and the positioning pins are made of a magnetically adsorbable material.

[0013] Preferably, the flatness adjustment structure specifically includes three internally threaded adjusting cylinders fixedly installed on the bottom surface of the support base, adjusting bolts threadedly connected to the three adjusting cylinders respectively, and rubber anti-slip pads fixed to the bottom of the adjusting bolts. The level calibrator is a bubble level embedded in the upper surface of the turntable.

[0014] Preferably, the drive assembly includes an internal gear ring coaxially fixed to the bottom surface of the turntable, a stepper motor installed at the bottom of the support base, and a spur gear fixed to the output shaft of the stepper motor and meshing with the internal gear ring. A control panel is provided on the outer wall of the front side of the support base.

[0015] Preferably, the clamping cylinder is interference-fitted with the rubber test tube cap.

[0016] The erythrocyte sedimentation rate (ESR) testing frame of this utility model has the following advantages:

[0017] 1. This erythrocyte sedimentation rate (ESR) testing rack utilizes a test tube insertion slot and a test tube clearance slot to initially position the ESR tube. The fit between the inner diameter of the clamping cylinder and the rubber test tube cap, along with the continuous elasticity compensation of the tension spring, effectively eliminates the angular deviation problem existing in traditional slot-type positioning, ensuring that the test tube remains absolutely vertical and guaranteeing the authenticity of the erythrocyte sedimentation trajectory.

[0018] 2. This erythrocyte sedimentation rate (ESR) testing frame utilizes a drive component to rotate the ESR observation frame, thereby rotating multiple ESR tubes on the ESR observation frame to face the testing personnel. This design transforms the traditional linear arrangement of test tubes into a dynamic ring arrangement, ensuring that the testing personnel always read the scale markings from a 90° vertical perspective, eliminating parallax errors caused by strabismus.

[0032] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an erythrocyte sedimentation rate (ESR) testing frame.

[0033] like Figure 1-6 As shown, the present invention provides an erythrocyte sedimentation rate (ESR) testing frame, comprising: an ESR tube, a rotating base, an ESR observation frame, an assembly structure, and a flatness adjustment structure.

[0034] The blood sedimentation tube consists of a transparent test tube 10 and a rubber test tube cap 11 that can be detachably installed at the top of the transparent test tube 10.

[0035] The rotating base includes a horizontally arranged cylindrical support 20. A circular groove is formed at the center of the upper surface of the support 20. A turntable 21 is rotatably mounted in the groove via bearings. The support 20 contains a drive assembly for rotating the turntable 21. The drive assembly includes an internal gear ring 70 coaxially fixed to the bottom surface of the turntable 21, a stepper motor 71 mounted on the bottom of the support 20, and a spur gear 72 fixed to the output shaft of the stepper motor 71 and meshing with the internal gear ring 70. A control panel is provided on the front outer wall of the support 20. The control panel controls the rotation of the stepper motor 71. When the stepper motor 71 rotates, it drives the spur gear 72 to rotate. The spur gear 72 meshes with the internal gear ring 70 to drive the turntable 21 to rotate.

[0036] The erythrocyte sedimentation rate (ESR) observation frame includes an assembly plate 30 coaxially mounted with a turntable 21. A cylindrical test tube limiting block 31 is coaxially fixed at the upper center of the assembly plate 30. Multiple vertically extending test tube clearance grooves 32 are arranged in a circular array on the circumferential sidewall of the test tube limiting block 31. A test tube insertion groove 33 corresponding to the position of the test tube clearance groove 32 is provided along the circumferential direction on the upper surface of the assembly plate 30. An elastic clamping component is provided at the upper end of the test tube limiting block 31. A scale marking line extending along the axial direction is provided on the outer surface of the test tube limiting block 31. A transparent test tube 10 is inserted into the test tube insertion groove 33, and then one side of the transparent test tube 10 is aligned with the test tube clearance groove 32, thereby initially positioning the transparent test tube 10.

[0037] The elastic clamping assembly includes a support plate 40 fixed to the upper surface of the test tube limiting block 31 by a column. The support plate 40 has multiple through holes arranged in a circumferential array. A pull rod 41 slides through each through hole. The upper end of the pull rod 41 is fixed to a limiting plate 42, and the lower end passes through the through hole and is fixedly connected to a clamping cylinder 43. A tension spring 44 is sleeved on the pull rod 41, with its two ends fixedly connected to the limiting plate 42 and the support plate 40 respectively. The clamping cylinder 43 is interference-fitted with the rubber test tube cap 11. During operation, lifting the limiting plate 42 can stretch the tension spring 44, causing the clamping cylinder 43 to rise. When the transparent test tube 10 is inserted into the test tube insertion slot 33, the limiting plate 42 is released, and the tension spring 44 returns to its original position, causing the clamping cylinder 43 to fit onto the surface of the rubber test tube cap 11. Then, the continuous elastic force of the tension spring 44 is used to compensate for the erythrocyte sedimentation rate tube to remain absolutely vertical.

[0038] The test tube insertion groove 33 and the test tube clearance groove 32 can be used to initially position the erythrocyte sedimentation rate tube. The inner diameter of the clamping cylinder 43 and the rubber test tube cap 11 are matched, and the continuous elastic force compensation of the tension spring 44 effectively eliminates the angle deviation problem of traditional slot-type positioning. The erythrocyte sedimentation rate tube remains absolutely vertical, ensuring the authenticity of the erythrocyte sedimentation trajectory.

[0039] The assembly structure is set between the bottom surface of the assembly plate 30 and the upper surface of the turntable 21 to realize the axial positioning assembly of the erythrocyte sedimentation rate (ESR) observation frame and the rotating base. The assembly structure includes four cylindrical positioning pins 50 that are vertically fixed in a circumferential array on the upper surface of the turntable 21, and four positioning holes correspondingly opened on the bottom surface of the assembly plate 30. A permanent magnet 51 is embedded in the bottom of the positioning hole. The positioning pins 50 are made of magnetically adsorbable material. After the ESR tube is fixed on the ESR observation frame, the positioning pins 50 are inserted into the positioning holes and the permanent magnets 51 are used to attract the positioning pins 50, so that the assembly plate 30 and the turntable 21 can be assembled into one unit.

[0040] The drive component can be used to rotate the erythrocyte sedimentation rate (ESR) observation frame, thereby rotating multiple ESR tubes on the frame to face the tester. This design transforms the traditional linear arrangement of test tubes into a dynamic ring arrangement, ensuring that the tester always reads the scale markings from a 90° vertical angle, eliminating parallax errors caused by strabismus.

[0041] The flatness adjustment structure includes three height-adjusting feet arranged in an equilateral triangle on the bottom surface of the support base 20, and a level calibrator set on the upper surface of the turntable 21. Specifically, the flatness adjustment structure includes three internally threaded adjusting cylinders 60 fixedly installed on the bottom surface of the support base 20, adjusting bolts 61 threadedly connected to the three adjusting cylinders 60, and rubber anti-slip pads 62 fixed to the bottom of the adjusting bolts 61. The level calibrator is a bubble level 63 embedded in the upper surface of the turntable 21. The adjusting cylinders 60 and adjusting bolts 61, which are threaded together, form an independent height adjustment unit. The bubble level 63 embedded in the turntable 21 displays the horizontal status of the rotating base. When the bubble deviates from the center, it indicates that the support surface is tilted or uneven, and the height needs to be adjusted by adjusting bolts 61 to compensate, thereby adjusting the flatness of the device.

[0042] Working principle:

[0043] Mechanical prepositioning

[0044] The test tube insertion groove 33 and the test tube clearance groove 32 form a guide channel. When the transparent test tube 10 is inserted into the test tube insertion groove 33, the transparent test tube 10 contacts the test tube clearance groove 32 to achieve coarse positioning of the transparent test tube 10.

[0045] Elastic self-compensating clamping

[0046] The inner diameter of the clamping cylinder 43 forms an interference fit with the rubber test tube cap 11 (interference amount 0.05-0.15mm), and the tension spring 44 provides a continuous downward clamping force (5-8N). After the blood sedimentation tube is inserted, the rubber test tube cap 11 will enter the clamping cylinder 43 to maintain the verticality of the blood sedimentation tube.

[0047] Magnetic quick assembly

[0048] The positioning pin 50 and the permanent magnet 51 form a magnetic connection, realizing the axial positioning of the assembly plate 30 and the turntable 21, while supporting quick disassembly and replacement.

[0049] Three-point fine-tuning mechanism

[0050] The height of the support base 20 is independently adjusted by the three adjusting bolts 61 through the threaded pair. The equilateral triangle layout forms a rigid statically determinate support. Rotating the adjusting bolts 61 changes the height of the support base 20. Observe the bubble level 63 on the turntable 21 until the bubble is centered.

[0051] Gear drive

[0052] The coaxial spur gear 72 of the output shaft of the stepper motor 71 meshes with the internal gear ring 70 at the bottom of the turntable 21, converting the torque of the stepper motor 71 into a 360° rotational motion of the turntable.

[0053] Circular dynamic positioning

[0054] Turntable 21 drives assembly plate 30 and erythrocyte sedimentation rate observation frame to rotate as a whole, rotating the transparent test tubes 10 in the circular array to the front of the tester in sequence, ensuring that the axis of the transparent test tube 10 forms a 90° orthogonal angle with the line of sight during each reading, thus eliminating the parallax error of traditional linear arrangement.

[0055] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
