Description

Technical Field

[0001] This utility model belongs to the field of medical testing equipment technology, and in particular to a clinical body fluid observation and testing device. Background Technology

[0002] In clinical practice, observing and testing a patient's bodily fluids (such as blood, urine, and cerebrospinal fluid) is an important means of diagnosing diseases and assessing the condition. Currently, the most common clinical method for observing and testing bodily fluids involves medical staff placing the fluid sample on a glass slide and then observing it under a microscope. However, the sample lacks an effective fixation and protection structure during the testing process, making it prone to displacement and affecting the accuracy of the test.

[0003] A search revealed Chinese patent documents (authorization announcement number CN222998824U), which disclose a clinical body fluid observation and testing device, relating to the field of clinical testing technology. This application uses a movable component to facilitate the smooth movement of the test tube containing body fluid, enabling rapid comparison of the body fluid with color calipers and improving the efficiency of the testing device in detecting body fluid. A fixing component is used to securely fix the test tube containing body fluid. This device can meet basic usage requirements. However, the lack of an effective fixation and protection structure for the sample during the testing process makes it prone to displacement, affecting the accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to provide a clinical body fluid observation and detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clinical body fluid observation and detection device, comprising a base for connecting to the outside, two slide rails for limiting the direction of movement fixedly installed on the top of the base, and a movable frame slidably installed between the two slide rails; The movable frame has a cross-shaped groove inside to provide installation space. A buffer spring for providing adaptive elasticity is connected inside the cross-shaped groove. One end of the buffer spring is connected to a cross-shaped moving disk for pressing against it. The cross-shaped moving disk is slidably disposed inside the cross-shaped groove. A position sensor for detecting the position of the cross-shaped moving disk is installed on the side of the cross-shaped moving disk near the buffer spring. A receiver for cooperating with the position sensor is installed on the vertical inner wall of the cross-shaped groove away from the position sensor.

[0006] Preferably, a fixed frame is fixedly installed on the top of the base, and a second telescopic rod for controlling the position of the movable frame is installed inside the fixed frame. The movable part of the second telescopic rod is connected to a coupling. The end of the coupling is connected to the side of the cross movable disc away from the buffer spring. A movable frame is rotatably installed at the end of the fixed frame, and a guide frame for providing motion guidance is fixedly installed at the end of the movable frame away from the fixed frame.

[0007] Preferably, the guide frame has an adjustable telescopic plate slidably mounted inside, and the end of the telescopic plate is fitted with an upper pressure column for fixing the upper surface of the sample plate.

[0008] Preferably, the fixed frame is connected to two sides with connecting spring assemblies for providing the pressure of the upper pressure column on the sample plate, the movable frame is equipped with connecting rods for connecting to the connecting spring assemblies on both sides, and the guide frame is equipped with a handle on the top for the operator to control the position of the guide frame.

[0009] Preferably, a fixing block is fixedly installed on the side of the fixing frame, a first telescopic rod is installed on the top of the fixing block, and a side locking clamp for pressing the guide frame is rotatably installed on the side of the fixing frame, and the movable part of the first telescopic rod is movably connected to the side of the side locking clamp.

[0010] Preferably, a fixed support is fixedly installed on the top of the base, and four adjustment locking holes for adjustment are symmetrically arranged on the top of the fixed support and the movable frame.

[0011] Preferably, an L-shaped positioning block for fixing is installed on the top of the four adjustment locking holes, and the surface of the L-shaped positioning block is provided with a locking bolt hole for locking the L-shaped positioning block in conjunction with the adjustment locking hole. A sample placement plate for placing clinical body fluid observation and testing is provided between the four L-shaped positioning blocks.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This clinical body fluid observation and testing device significantly improves operational convenience and position adjustment accuracy thanks to its combined structure of a cross-shaped moving disc, a second telescopic rod, a position sensor, and a receiver. The cross-shaped moving disc slides within the cross-shaped groove of the moving frame. Driven by the second telescopic rod and coupling, the moving frame moves smoothly along the base's slide rails, enabling fine-tuning of the sample placement plate's horizontal position. The position sensor moves synchronously with the cross-shaped moving disc, interfacing with the receiver to accurately report the moving frame's position, eliminating the need for repeated manual calibration and reducing operational errors. Simultaneously, the buffer spring within the cross-shaped groove provides adaptive elastic cushioning, preventing rigid collisions between components. This structure allows medical personnel to achieve precise positioning solely through device operation, eliminating the need for manual sample movement, greatly simplifying the operation process and saving adjustment time. It is particularly suitable for multi-field detection scenarios requiring frequent sample position adjustments.

[0013] This clinical body fluid observation and testing device effectively solves the problem of sample displacement thanks to its triple fixation structure, which combines L-shaped positioning blocks for limiting movement, vertical fixation of the upper pressure column, and lateral locking of the side clamps. First, the four L-shaped positioning blocks can be flexibly adjusted according to the width of the sample placement plate. They do not need to be completely flush against all four sides; only two adjacent sides of the sample placement plate need to be in contact with the L-shaped positioning blocks. Adjusting the locking holes and locking bolt holes achieves initial limiting, preventing large-scale horizontal displacement of the sample. Second, the upper pressure column at the end of the telescopic plate precisely fits against the upper surface of the sample placement plate. Combined with the elastic pressure provided by the connecting spring assembly and connecting rod, it forms a stable vertical fixation, preventing the sample from shifting vertically. Finally, the first telescopic rod drives the side locking clamp to clamp the guide frame, further strengthening the fixing effect of the upper pressure column. This, along with the horizontal limiting of the L-shaped positioning blocks, ensures that the sample remains stable throughout the testing process, completely resolving the displacement problem caused by a lack of effective fixation and guaranteeing testing accuracy.

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] like Figures 1 to 5 The clinical body fluid observation and testing device shown includes a base 1 for external connection. Two slide rails 301 for limiting the direction of movement are fixedly installed on the top of the base 1, and a movable frame 3 is slidably installed between the two slide rails 301. The movable frame 3 has a cross-shaped groove 302 inside to provide installation space. A buffer spring 304 for providing adaptive elasticity is connected inside the cross-shaped groove 302. One end of the buffer spring 304 is connected to a cross-shaped moving disk 303 for pressing. The cross-shaped moving disk 303 is slidably disposed inside the cross-shaped groove 302. A position sensor 305 for detecting the position of the cross-shaped moving disk 303 is installed on the side of the cross-shaped moving disk 303 near the buffer spring 304. A receiver 306 for cooperating with the position sensor 305 is installed on the vertical inner wall of the cross-shaped groove 302 away from the position sensor 305. The second telescopic rod 203 connected to the fixed frame 101 is activated. The movable part of the second telescopic rod 203 drives the cross-shaped moving disk 303 to slide in the cross-shaped groove 302 inside the movable frame 3 through the coupling 204. Since the cross-shaped moving disk 303 is slidably disposed in the cross-shaped groove 302, and the moving frame 3 is slidably mounted on the top of the base 1 via two slide rails 301, the sliding of the cross-shaped moving disk 303 will synchronously drive the moving frame 3 to move along the length direction of the slide rails 301, thereby adjusting the position of the L-shaped positioning block 402 on the moving frame 3, and indirectly pushing the sample placement plate 5 to make slight adjustments in the horizontal direction to adapt to the position requirements of subsequent observation and detection (during this process, the sample placement plate 5 always slides between the four L-shaped positioning blocks 402 and does not contact the fixed base 4). During the movement of the cross-shaped moving disk 303, the position sensor 305 installed near the buffer spring 304 moves synchronously with the cross-shaped moving disk 303. When the cross-shaped moving disk 303 moves to the target position, the position sensor 305 will form a signal interface with the receiver 306 on the vertical inner wall of the cross groove 302 away from the position sensor 305. After receiving the signal from the position sensor 305, the receiver 306 can feed back to the equipment control system to indicate that the moving frame 3 has reached the set position and stop the drive of the second telescopic rod 203. At the same time, the buffer spring 304 in the cross groove 302 will undergo elastic deformation due to the movement of the cross-shaped moving disk 303, providing adaptive elastic buffering to avoid rigid collision between the cross-shaped moving disk 303 and the inner wall of the cross groove 302, protecting the components and improving the stability of adjustment.

[0020] A fixed frame 101 is fixedly installed on the top of the base 1. A second telescopic rod 203 for controlling the position of the movable frame 3 is installed inside the fixed frame 101. A coupling 204 is connected to the movable part of the second telescopic rod 203. The end of the coupling 204 is connected to the side of the cross movable disk 303 away from the buffer spring 304. A movable frame 103 is rotatably installed at the end of the fixed frame 101. A guide frame 106 for providing motion guidance is fixedly installed at the end of the movable frame 103 away from the fixed frame 101.

[0021] The guide frame 106 has an adjustable telescopic plate 107 slidably installed inside. The end of the telescopic plate 107 is equipped with an upper pressure column 108 for fixing the upper surface of the sample plate. The fixed frame 101 has connecting spring groups 102 connected to both sides to provide the upper pressure column 108 to press against the sample plate. The movable frame 103 has connecting rods 104 connected to the connecting spring groups 102 on both sides. The top of the guide frame 106 is equipped with a handle 105 for the operator to control the position of the guide frame 106. The operator holds the handle 105 on the top of the guide frame 106 and applies force to rotate the movable frame 103 (the movable frame 103 is rotatably installed at the end of the fixed frame 101), so that the movable frame 103 drives the guide frame 106 to flip towards the sample placement plate 5 until the telescopic plate 107 below the guide frame 106 is aligned with the upper surface of the sample placement plate 5. The telescopic plate 107 is pushed to slide inside the guide frame 106, and the extension length of the telescopic plate 107 is adjusted so that the upper pressure column 108 at the end of the telescopic plate 107 is precisely fitted to the designated position on the upper surface of the sample placement plate 5. During this process, the connecting spring groups 102 on both sides of the fixed frame 101 are connected to the connecting rods 104 on both sides of the movable frame 103 to generate elastic tension, providing a downward force for the movable frame 103, which in turn drives the guide frame 106 and the upper pressure column 108 to apply a stable compressive force to the sample placement plate 5, preventing the sample placement plate 5 from loosening in the vertical direction (at this time, the sample placement plate 5 still remains in a state of not contacting the fixed seat 4, and is only limited by the L-shaped positioning block 402 and the upper pressure column 108).

[0022] A fixing block 2 is fixedly installed on the side of the fixing frame 101. A first telescopic rod 201 is installed on the top of the fixing block 2. A side locking clamp 202 for pressing the guide frame 106 is rotatably installed on the side of the fixing frame 101. The movable part of the first telescopic rod 201 is movably connected to the side of the side locking clamp 202. When the first telescopic rod 201 installed on the top of the fixing block 2 is activated (the fixing block 2 is fixedly installed on the side of the fixing frame 101), the movable part of the first telescopic rod 201 extends towards the side locking clamp 202. Since the side locking clamp 202 is rotatably installed on the side of the fixing frame 101 and the movable part of the first telescopic rod 201 is movably connected to the side of the side locking clamp 202, the thrust of the first telescopic rod 201 will drive the side locking clamp 202 to rotate around the rotation point on the side of the fixing frame 101 until the end of the side locking clamp 202 is tightly attached to the side of the guide frame 106, thereby achieving lateral locking of the guide frame 106 and further strengthening the fixing effect of the upper pressure column 108 on the sample placement plate 5. The operator tightens the bolts in the locking bolt holes 403 of the L-shaped positioning block 402, so that the bolts pass through the locking bolt holes 403 and are tightly threaded into the adjusting locking holes 401, thus firmly fixing the L-shaped positioning block 402 on the fixed base 4 and the moving frame 3. At this time, the sample placement plate 5 is stably restricted between the four L-shaped positioning blocks 402, and is fixed in the vertical direction by the upper pressure column 108, ultimately achieving all-round stable fixation (the sample placement plate 5 does not contact the fixed base 4 throughout the process). The equipment completes the pre-test preparation work and can begin to observe and test the clinical body fluid samples on the sample placement plate 5.

[0023] A fixed base 4 for support is fixedly installed on the top of the base 1. Four adjustment locking holes 401 for adjustment are symmetrically arranged on the top of the fixed base 4 and the movable frame 3. L-shaped positioning blocks 402 for fixing are installed on the top of the four adjustment locking holes 401. The surface of the L-shaped positioning blocks 402 is provided with locking bolt holes 403 for locking the L-shaped positioning blocks 402 in conjunction with the adjustment locking holes 401. A sample placement plate 5 for placing clinical body fluid observation and testing is arranged between the four L-shaped positioning blocks 402. The operator needs to adjust the position of the four L-shaped positioning blocks 402 in advance at the adjustment locking holes 401 on the top of the fixed base 4 and the movable frame 3 according to the width of the sample placement plate 5 containing clinical body fluid samples: the L-shaped positioning blocks 402 are initially connected to the adjustment locking holes 401 through the locking bolt holes 403 (the bolts do not need to be tightened, only slightly fixed to ensure that the L-shaped positioning blocks 402 do not slide arbitrarily). It should be noted that the four L-shaped positioning blocks 402 do not need to be completely aligned with the four sides of the sample placement plate 5. It is only necessary to make two adjacent sides of the sample placement plate 5 (such as the left side and the front side) fit against the inner side of the corresponding L-shaped positioning block 402. The horizontal movement of the sample placement plate 5 can be initially restricted by the limiting of these two sides, thus forming a suitable placement space. Subsequently, the sample placement plate 5 is placed in the space between the four L-shaped positioning blocks 402. At this time, only two adjacent sides of the sample placement plate 5 need to be in contact with the inner side of the corresponding L-shaped positioning block 402, without directly contacting the top surface of the fixed base 4 and the moving frame 3. The remaining two sides can maintain a certain gap with the L-shaped positioning blocks 402. The initial positioning by the L-shaped positioning blocks 402 with the contacting sides can prevent the sample placement plate 5 from shifting significantly during subsequent position adjustments, laying the foundation for subsequent precise adjustments. If the position of the sample placement plate 5 needs to be finely adjusted during the observation and testing process, the locking bolts of the L-shaped positioning blocks 402 can be loosened first (no need to completely disassemble, just loosen them until the L-shaped positioning blocks 402 can slide). The sample placement plate 5 is moved by the moving frame 3 and the L-shaped positioning block 402 (achieved by reverse driving the first telescopic rod 201, causing the upper pressure column 108 to disengage from the upper surface of the sample placement plate 5). The driving operation of the second telescopic rod 203 in step two is repeated. Through the signal cooperation between the position sensor 305 and the receiver 306, the moving frame 3 and the L-shaped positioning block 402 are driven, so that the sample placement plate 5 is finely adjusted in position by the L-shaped positioning block 402 through the two sides that are in contact (the sample placement plate 5 is always between the L-shaped positioning blocks 402, and is only limited by the two sides in contact and does not contact the fixed seat 4). After the adjustment is completed, the bolts of the L-shaped positioning block 402 are tightened again and the side locking clamp 202 is locked to ensure that the sample position always meets the observation requirements during the detection process.

[0024] To ensure that clinical body fluid observation and testing equipment is always in normal working condition, targeted measures should be developed from five core dimensions: environment, maintenance, materials, component compatibility, and personnel operation. These measures should mitigate interference from various factors, such as the temperature, humidity, cleanliness, and vibration of the operating environment, which directly affect sample stability and component accuracy. First, the equipment should be placed in a laboratory environment with a temperature controlled between 18-25℃ and a relative humidity of 40%-60%. This prevents metal components (such as the slide rail 301 and adjustment locking hole 401) from rusting due to high temperature and humidity, or the elasticity of the buffer spring 304 from weakening. Simultaneously, it should be kept away from areas with sudden temperature changes, such as air conditioning vents and heating pipes, to prevent changes in the properties of body fluid samples on the sample placement plate 5 due to temperature fluctuations. Second, the surrounding environment of the equipment should be cleaned regularly. The equipment surface should be wiped daily with a lint-free cloth, and the laboratory air should be purified weekly to prevent dust from entering the cross groove 302 and affecting the sliding accuracy of the cross moving disk 303, or adhering to the surface of the position sensor 305 and receiver 306 and interfering with signal transmission. In addition, the equipment must be placed on a stable experimental platform. Shock-absorbing pads can be installed at the bottom of the experimental platform to keep at least 1.5 meters away from high-frequency vibration equipment such as centrifuges and shakers, so as to prevent external vibrations from being transmitted to the moving frame 3 through the base 1, causing the sample placement plate 5 to shift or the field of view to become blurred.

[0025] Scientific maintenance is key to extending equipment life and ensuring normal operation. Monthly, quarterly, and annual maintenance plans should be developed. During monthly maintenance, focus on checking the extension and retraction of the first telescopic rod 201 and the second telescopic rod 203. Apply special grease to the moving parts of the telescopic rods to prevent jamming due to insufficient lubrication, which could affect the normal operation of the moving frame 3 or the side locking clamp 202. Simultaneously check the elasticity of the connecting spring assembly 102. If spring deformation or weakened tension is found, replace it with a spring of the same specification to ensure stable pressure from the upper pressure column 108 on the sample placement plate 5. During quarterly maintenance, disassemble the L-shaped positioning block 402 and wipe the inner walls of the adjusting locking hole 401 and the locking bolt hole 403 with alcohol to remove residual bodily fluids or rust, preventing bolts from being unable to be tightened smoothly. At the same time, clean the inside of the cross-shaped groove 302, blow out impurities with compressed air, and check the integrity of the buffer spring 304. Replace it immediately if it is broken or loses its elasticity. Annual maintenance requires contacting professional technicians to calibrate the signal accuracy of position sensor 305 and receiver 306 to ensure that the positioning error of the moving frame 3 does not exceed 0.01mm; at the same time, check the verticality of the upper pressure column 108. If tilting occurs, adjust the installation angle of the telescopic plate 107 in time to prevent uneven pressure from being applied to the sample placement plate 5, which could cause the sample to shift.

[0026] The selection of materials for equipment components must be adapted to the specific needs of clinical body fluid testing to avoid affecting normal operation due to materials that are not corrosion-resistant or lack strength. For components that come into direct contact with body fluids or are easily contaminated, such as the sample placement plate 5, acid and alkali resistant polytetrafluoroethylene is used, and the L-shaped positioning block 402 is made of 316L stainless steel with an anti-corrosion coating to prevent chemical components in body fluids such as blood and urine from corroding the components, causing deformation of the positioning block or damage to the bolt holes. The cross-shaped moving disk 303 and the cross-shaped groove 302 are made of high-strength aluminum alloy and are anodized to improve surface hardness and wear resistance, avoiding wear caused by long-term sliding and affecting the moving accuracy. In addition, a medical silicone pad is attached to the end of the upper pressure column 108 to increase friction with the sample placement plate 5 to prevent displacement and to avoid direct metal contact that could damage the glass slide. The silicone pad can also be removed and replaced periodically to ensure cleanliness and hygiene, meeting clinical infection control requirements.

[0027] Precise fit between components is the foundation for normal operation of the equipment and requires close attention during installation and use: When assembling the equipment, strictly control the parallelism between the slide rail 301 and the base 1, and the error must be controlled within 0.02mm to ensure that the moving frame 3 slides along the slide rail without deviation; the connection between the coupling 204 and the second telescopic rod 203 and the cross moving plate 303 must be coaxial. After installation, manually rotate the cross moving plate 303 to ensure that there is no jamming or loosening, so as to avoid uneven force when the telescopic rod is driven due to insufficient coaxiality, which may damage the components or affect the position adjustment. During use, after each adjustment of the L-shaped positioning block 402, the flatness of the contact edge between the positioning block and the sample placement plate 5 should be checked. If the contact gap is found to be too large, the positioning block shim with a suitable thickness should be replaced to ensure effective horizontal limiting. At the same time, when driving the side locking clamp 202, observe the force state of the guide frame 106. If lateral tilting occurs, adjust the installation position of the first telescopic rod 201 in time to prevent the side locking clamp 202 from applying excessive pressure to the guide frame 106, causing deformation and affecting the fixing effect of the upper pressure column 108.

[0028] Improper operation by personnel is a significant factor leading to equipment malfunction. Standardized operating procedures and regular training are essential. Operators must undergo professional training and pass an assessment before being allowed to work. Training content includes the functions of each component, operating procedures, and emergency handling methods. During daily operation, strictly follow the procedure of "initial positioning - precise adjustment - pressure fixing - overall locking." When placing the sample placement plate 5, handle it gently to avoid impacting the L-shaped positioning block 402, which could cause positioning misalignment. When adjusting the position of the moving frame 3, set the movement parameters through the equipment control panel; do not manually push the moving frame 3 to prevent damage to the cross-shaped moving disk 303 or the position sensor 305. When disassembling or installing the L-shaped positioning block 402, use a dedicated wrench to tighten the bolts with moderate force (torque controlled between 5-8 N·m) to avoid the positioning block slipping due to excessive looseness or the bolt hole threads being damaged due to excessive tightness. Furthermore, if the equipment malfunctions (such as the telescopic rod failing to extend or retract, or the sensor having no signal), the operator must immediately stop using the equipment, record the fault symptoms, and contact maintenance personnel. Do not disassemble components yourself to prevent the fault from escalating and affecting the normal operation of the equipment.

[0029] For emergency handling, the equipment is equipped with a fault alarm module. When the signal between the position sensor 305 and the receiver 306 is interrupted, the telescopic rod is overloaded, or the elasticity of the buffer spring 304 is abnormal, the equipment will automatically issue an audible and visual alarm and lock the operation to prevent forced operation from damaging components. At the same time, an emergency manual adjustment hole is reserved on the side of the base 1. In case of power failure or telescopic rod failure, a special wrench can be inserted into the hole to manually rotate and adjust the position of the moving frame 3 to ensure that the sample can still be tested in an emergency. In terms of compatibility and adaptation, for different sizes of slides used in clinical practice (such as 25mm×75mm regular slides and 18mm×18mm small slides), a replaceable silicone pad can be installed inside the L-shaped positioning block 402. By changing the pad of different thickness (0.5mm, 1mm), it can adapt to sample carriers of different thicknesses. In addition, the bottom of the sample placement plate 5 can be designed with a hollow structure to facilitate the combination of heating or cooling modules to meet the testing needs of temperature-sensitive body fluid samples (such as cerebrospinal fluid), further improving the clinical applicability of the equipment.

[0030] Working principle In use, this clinical body fluid observation and testing device firstly fixes four L-shaped positioning blocks 402 at the adjustment and locking holes 401 of the fixed base 4 and the moving frame 3, according to the width of the sample placement plate 5. No bolt tightening is required; simply aligning the adjacent sides of the sample placement plate 5 with the corresponding L-shaped positioning blocks 402 allows it to be placed between the L-shaped positioning blocks 402 without contacting the fixed base 4, thus achieving initial positioning. Next, the second telescopic rod 203 on the fixed frame 101 is activated. Its movable part, via the coupling 204, drives the cross-shaped moving disc 303 to slide within the cross-shaped groove 302 of the moving frame 3, causing the moving frame 3 to move along the slide rail 301 of the base 1. This causes the L-shaped positioning blocks 402 to fine-tune with the sample placement plate 5. The position sensor 305 and receiver 306 work together to confirm the position, and the buffer spring 304 provides cushioning. Next, hold the handle 105 of the guide frame 106, rotate the movable frame 103, and push the telescopic plate 107 to make the upper pressure column 108 fit against the upper surface of the sample placement plate 5. The connecting spring assembly 102 assists in applying pressure through the connecting rod 104. Then, activate the first telescopic rod 201 of the fixing block 2, push the side locking clamp 202 to lock the guide frame 106, and tighten the bolts of the L-shaped positioning block 402 to complete the all-round fixation. If fine-tuning is required during testing, loosen the bolts and the side locking clamp 202, and repeat the adjustment steps.
