Description

Technical Field

[0001] This utility model relates to the field of medical sample testing technology, and in particular to a sample processing medical testing auxiliary device. Background Technology

[0002] In medical testing, sample dilution is required. This application mainly focuses on the processing of blood samples in test tubes. Before testing, the blood samples in the test tubes are diluted to facilitate subsequent sample testing. Specifically, it is a device for diluting blood or urine samples in test tubes.

[0003] Patent document CN118583610A discloses a liquid addition and dilution device for medical testing, belonging to the field of medical device technology. It includes a base plate with a vertical plate on one side. Connecting rods and test tube racks are respectively connected to both sides of the vertical plate, and a housing is fixedly connected to the other end of each connecting rod. This invention utilizes movable blocks and movable plates. Moving the movable blocks adjusts the positions of the test tube trough and waste liquid trough, facilitating liquid addition with a dropper. Moving the movable plate adjusts the dropper position, allowing for fine-tuning and preventing liquid mixing that could affect test results. The combined use of a mixing auxiliary component and a splash-proof protection component, along with a mounting ring that limits and guides the connecting ring, allows the connecting ring to move into the reagent tube for mixing the solution after addition. The movable addition component allows for easy replacement of the entire addition assembly, preventing residual liquid inside the connecting tube from affecting different samples and thus impacting test results.

[0004] Although the above-mentioned application allows for mixing after liquid addition and then replacing the liquid addition component to avoid affecting the sample, in actual application, the test tubes containing the sample need to be inserted into the corresponding test tube positioning components. After insertion, the diluent cannot be added to the test tubes simultaneously. All sample test tubes need to be fully inserted before the diluent is added, which increases the waiting time for diluent addition, reduces the dilution operation time of the device, and thus reduces the operating efficiency of the testing personnel.

The output shaft of the stepper motor is fixedly connected to a turntable via a coupling. A support tube is fixedly mounted on the top of the turntable. The steering assembly allows for easy removal of the dilution and dispensing assembly from the top of the positioning box during use, facilitating subsequent cleaning of the device and maintenance of the components on the dilution and dispensing assembly, while preventing impurities or contaminants from falling into the interior of the positioning box during maintenance.

[0010] The dilution and dispensing assembly includes a horizontal plate fixedly installed on the top of a support tube, a material box fixedly installed on the top of the horizontal plate, an electric push rod fixedly installed on the bottom of the horizontal plate, a dispensing pipe fixedly installed on the bottom of the electric push rod, a discharge pipe connected to the bottom of the dispensing pipe, a solenoid valve connected to the surface of the discharge pipe, and one side of the dispensing pipe connected to the bottom of the material box via a telescopic flexible hose.

[0011] With the established positioning control and dilution dispensing components, diluent can be added to the corresponding test tubes after they are inserted into the positioning box, thus ensuring that the diluent is added to the previously inserted test tubes after all the sample test tubes have been fully inserted. Subsequently, the test tubes inserted first can be removed in sequence, reducing the waiting time for diluent addition and the dilution operation time of the device, thereby improving the operational efficiency of the testing personnel.

[0012] In a preferred embodiment, rubber plates are fixedly installed at the four corners of the base, and the lower surface of the rubber plates is provided with anti-slip texture.

[0013] The rubber plate facilitates the placement of the device during use, maintains the overall stability of the device, and increases the friction between the base and the test platform, preventing it from being easily shaken.

[0014] In a preferred embodiment, a protective ring is fixedly installed on the inner wall of the positioning hole on the positioning box. The protective ring is made of rubber and the inner side of the protective ring is set to a smooth state.

[0015] The protective ring can protect the surface of the test tube during use, thus preventing damage to the test tube during the testing process.

[0016] In a preferred embodiment, a slider is fixedly installed on the bottom wall of the turntable, the bottom of the slider contacts the top of the housing, the top of the housing has a circular hole for the coupling to pass through, the inner wall of the circular hole is rotatably connected to the surface of the coupling, and a heat dissipation hole is provided on one side of the housing, the inner wall of the heat dissipation hole is inlaid with a mesh plate.

[0017] The slider and turntable are designed to support the support tube during use, preventing excessive force on the stepper motor's output shaft and thus avoiding damage to the stepper motor when the support tube rotates.

[0018] In a preferred embodiment, a compression ring is fixedly installed at the bottom of the filling tube, the lower surface of the compression ring has anti-slip texture, and the compression ring is made of silicone.

[0022] In a preferred embodiment, the touch switch, electric actuator, stepper motor, and solenoid valve are all electrically connected to the PLC controller.

[0023] As can be seen from the above, the sample processing medical testing auxiliary device provided by this utility model has the following technical effects.

[0024] Firstly, through the positioning control component and dilution dispensing component, after inserting the test tube containing blood or urine samples into the positioning box, the corresponding test tube can be dispensed with diluent. Thus, after all the sample test tubes are fully inserted, the previously inserted test tubes have already been dispensed with diluent, and the test tubes inserted first can then be removed in sequence. This reduces the waiting time for diluent dispensing, as well as the dilution operation time of the device, and improves the operational efficiency of the testing personnel.

[0025] Secondly, the dilution and dispensing component can be easily removed from the top of the positioning box during use, making it easier to clean the device and maintain the components on the dilution and dispensing component, and preventing impurities or contaminants from falling into the positioning box during maintenance.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Reference Figures 1-6 A sample processing medical testing auxiliary device includes a base 1, a positioning control component 2 and a steering component 3 fixedly installed on the upper surface of the base 1, and a dilution dispensing component 4 provided on the top of the steering component 3.

[0035] The positioning control component 2 includes a positioning box 200 fixedly installed on the base 1. The inner bottom wall of the positioning box 200 has a positioning hole, and a touch switch 201 is fixedly installed on the inner bottom wall of the positioning hole. A protective tube 202 is fixedly installed on the inner top wall of the positioning box 200 at the position of the positioning hole. A PLC controller 203 is also fixedly installed on one side of the upper surface of the base 1. A protective ring 204 is fixedly installed on the inner wall of the positioning hole on the positioning box 200. The protective ring 204 is made of rubber, and the inner side of the protective ring 204 is set to a smooth state. The protective ring 204 can protect the surface of the test tube during use, thereby avoiding damage to the test tube during the inspection process.

[0036] The steering assembly 3 includes a housing 300 fixedly mounted on the upper surface of the base 1. A stepper motor 301 is fixedly mounted on the inner bottom wall of the housing 300. The output shaft of the stepper motor 301 is fixedly connected to a turntable 302 via a coupling. A support tube 303 is fixedly mounted on the top of the turntable 302. The steering assembly 3 facilitates the removal of the dilution dispensing assembly 4 from the top of the positioning box 200 during use, making it easier to clean the device and maintain the components on the dilution dispensing assembly 4, while preventing impurities or contaminants from falling in during maintenance. Inside the positioning box 200, a slider 304 is fixedly installed on the bottom wall of the turntable 302. The bottom of the slider 304 contacts the top of the housing 300. The top of the housing 300 has a circular hole for the coupling to pass through. The inner wall of the circular hole is rotatably connected to the surface of the coupling. A heat dissipation hole is provided on one side of the housing 300. The inner wall of the heat dissipation hole is inlaid with a mesh plate. The slider 304 and the turntable 302 can support the support tube 303 during use, so as to prevent the output shaft of the stepper motor 301 from being damaged by excessive force when the support tube 303 rotates.

[0037] The dilution dispensing assembly 4 includes a horizontal plate 400 fixedly installed on the top of a support tube 303. A material box 401 is fixedly installed on the top of the horizontal plate 400. An electric push rod 402 is fixedly installed on the bottom of the horizontal plate 400. A dispensing tube 403 is fixedly installed on the bottom of the electric push rod 402. A discharge tube 404 is connected to the bottom of the dispensing tube 403. A solenoid valve 405 is connected to the surface of the discharge tube 404. One side of the dispensing tube 403 is connected to the bottom of the material box 401 via a telescopic hose 409. A compression ring 406 is fixedly installed on the bottom of the dispensing tube 403. The lower surface of the compression ring 406 has anti-slip textures and is made of silicone. The compression ring 406 can protect the top of the test tube during use. A liquid dispensing tube 407 is connected to the top of the material box 401 for dispensing liquid. The top of tube 407 is threaded with a sealing cap 408. The surface of the sealing cap 408 has a groove. An observation window is provided on one side of the material box 401. The sealing cap 408 can seal the opening of the liquid addition tube 407 during use. At the same time, the liquid addition tube 407 facilitates the subsequent addition of diluent. The positioning control component 2 and the dilution addition component 4 are set up so that after the test tube containing blood or urine sample is inserted into the positioning box 200, the corresponding test tube can be added with diluent. Thus, after all the sample test tubes are fully inserted, the previously inserted test tubes have been added with diluent. Then, the test tubes inserted at the first time can be taken out in sequence, which reduces the waiting time for diluent addition and also reduces the dilution operation time of the device, improving the operating efficiency of the testing personnel.

[0038] Reference Figure 3 In a preferred embodiment, rubber plates 5 are fixedly installed at the four corners of the bottom of the base 1. The lower surface of the rubber plates 5 is provided with anti-slip texture. The rubber plates 5 facilitate the placement of the device during use, maintain the overall stability of the device, and increase the friction between the base 1 and the test platform to prevent it from being easily shaken.

[0039] Reference Figures 1-6 In a preferred embodiment, the touch switch 201, electric push rod 402, stepper motor 301, and solenoid valve 405 are all electrically connected to the PLC controller 203. The PLC controller 203 is a digital computing electronic system designed for industrial applications. It uses a programmable memory to store operation instructions for performing logic operations, sequential control, timing, counting, and arithmetic operations. Through digital and analog inputs and outputs, it controls various types of machinery or production processes. The working principle of the PLC controller 203 can be briefly described as: centralized sampling, centralized output, and periodic cyclic scanning.

[0040] The on / off status of all input terminals is read sequentially, and the read information is stored in the input image register. At this time, the input image register is refreshed. Since the PLC uses centralized sampling, even if the input changes during the program processing stage, the contents of the input image register will not change until the input sampling stage of the next cycle.

[0041] PLCs operate using a continuously looping sequential scanning method. The time taken for each scan is called the scan cycle or working cycle. Following a top-to-bottom, left-to-right sequence, the ladder diagram program is scanned line by line, and logical operations are performed based on the results sampled in the input image registers. The results are then stored in the relevant image registers.

[0042] If a program jump instruction is encountered, the jump address is determined based on whether the jump condition is met. Since the PLC operates serially, the PLC's execution result depends on the order of the ladder diagram.

[0043] After timing processing is complete, the state of each point in all output image registers is transferred to the output latch, and then the external load is driven through the output terminal.

[0044] Working principle: Place the device on the inspection table, loosen the sealing cap 408, and add diluent to the material box 401 through the liquid addition tube 407. When diluting is needed for test tubes containing urine or blood, insert the test tube into the corresponding positioning hole in the positioning box 200. During insertion, the touch switch 201 is squeezed, and then the PLC controller 203 controls the corresponding electric push rod 402 to extend. After the electric push rod 402 extends to the preset height, the PLC controller 203 controls the solenoid valve 405 to open. The liquid in the material box 401 enters the filling tube 403 through the telescopic hose 409, and then enters the corresponding test tube through the discharge tube 404. After the diluent is added, the PLC controller 203 controls the... The electric push rod 402 is shortened accordingly, so that diluent can be added immediately after the test tube is inserted. After the last test tube is inserted, the previously inserted test tubes can be removed in the order of insertion, thereby reducing the waiting time for diluent addition. After all additions are completed, the PLC controller 203 can control each component to stop working. When it is necessary to maintain or repair the diluent addition component 4 and the positioning box 200 separately, the PLC controller 203 can control the stepper motor 301 to rotate 90-180 degrees, so that the top of the diluent addition component 4 and the positioning box 200 do not overlap, thus allowing for component inspection and maintenance, and preventing parts or impurities from falling into the interior of the positioning box 200 during inspection and maintenance.

[0045] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
