Description

Technical Field

[0001] The invention relates to the technical field of clinical molecular specimen viscosity reduction equipment, and in particular to a viscosity reduction device for viscous clinical molecular test specimens. Background Art

[0002] In clinical molecular testing, viscous specimens are often encountered. Due to their high viscosity, such specimens are very difficult to handle, which not only affects the efficiency of the test, but may also affect the accuracy of the test results. At present, although there are some devices for handling viscous liquids, these devices are often relatively simple in function, such as only having a stirring function or a heating function, and it is difficult to simultaneously meet the needs of treating viscous clinical molecular test specimens in multiple ways to achieve effective viscosity reduction. Although the stirring device can mix the specimen components evenly to a certain extent, for some specimens with extremely high viscosity, simple stirring may not be able to effectively reduce their viscosity.

[0003] The heating device can assist in reducing the viscosity by changing the physical properties of the specimen. However, the viscosity reduction effect may be limited when using heating alone, and it may not be possible to ensure that all parts of the specimen are heated evenly. Moreover, during the discharge process, existing processing devices are prone to problems such as liquid splashing, resulting in specimen loss or pollution to the surrounding environment. At the same time, there is a lack of effective follow-up treatment methods for specimens after viscosity reduction, such as disinfection, which increases the risks that may arise during the subsequent use of the specimen. Therefore, it is of great practical significance to develop a device that can integrate multiple treatment methods to effectively reduce the viscosity of viscous clinical molecular test specimens and has advantages in discharge and subsequent processing.

[0030] 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 embodiments described below 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 making creative work are within the scope of protection of the present invention. In order to make a clearer explanation and description of the technical solutions and implementation methods of the present invention, the following introduces a preferred specific embodiment for implementing the technical solutions of the present invention.

[0031] Example 1: In a viscosity reduction device for viscous clinical molecular test specimens, the base 11 of the support assembly 1 is placed horizontally on an operating table. The bottom end of the guide rail 12 is locked to the rear side of the top surface of the base 11 by screws. A groove is provided on the front side of the top surface of the base 11 for stable placement of the material cup 5. The rear plate 21 and front plate 22 of the linear actuator 2 are positioned on the front and rear sides of the guide rail 12 via four rollers 23 arranged at the four corners. A servo motor 24 is bolted to the right side of the rear surface of the rear plate 21. The output shaft of the servo motor 24 extends through a through hole provided on the right side of the rear plate 21. A bearing installed in the through hole ensures stable rotation of the output shaft. The output shaft is connected to a rubber roller 25 in contact with the right side surface of the guide rail 12 via a coupling. A circular hole is provided in the interior of a support plate 26 fixed to the front surface of the front plate 22 for passing through and securing the tank 31 of the ultrasonic agitation viscosity reduction mechanism 3.

[0032] The top surface of the tank 31 of the ultrasonic agitation viscosity reduction mechanism 3 includes through-holes for the feed hopper 33 and the output shaft of the agitation motor 34, respectively. Sealing rings and sealed bearings installed within these through-holes ensure tight sealing. The agitation motor 34 is fixed to the top surface of the tank 31, its output shaft connected to the ribbon agitator 32 via a coupling. Openings are provided on the left and right sidewalls of the tank 31, housing two ultrasonic generators 35, their ultrasonic emitting tips facing the interior of the tank 31. Several electric heating wires 36 are fixed to the inner sidewalls of the tank 31 in a circular array centered around the axis of the tank 31. The top port of the discharge hopper 41 of the material control assembly 4 is connected to the bottom port of the tank 31 via a flange. An electrically controlled valve 42 is secured to the bottom port of the discharge hopper 41, which in turn is secured to a flow conduit 43 at its outlet. The interior spaces of the discharge hopper 41, the electrically controlled valve 42, and the flow conduit 43 are all connected to the inner cavity of the tank 31.

[0033] During operation, the viscous clinical molecular test specimen is put into the tank body 31 from the feed hopper 33, the stirring motor 34 is started to drive the ribbon stirring paddle 32 to stir, and the ultrasonic generator 35 is turned on to perform cavitation and crushing treatment on the specimen, and the electric heating wire 36 is used to heat the specimen. The servo motor 24 is turned on to drive the rubber roller 25 to rotate, so that the linear movable drive member 2 moves up and down along the guide rail 12, thereby driving the ultrasonic stirring viscosity reduction mechanism 3 and the material control component 4 to move up and down, so that the bottom port of the material control component 4 is always at a position 1.0cm-2.0cm above the liquid level inside the material cup 5. After the treatment is completed, the electric control valve 42 is opened, and the sample after viscosity reduction flows into the material cup 5 through the guide pipe 43, and is mixed with the disinfectant solution in the material cup 5 for disinfection treatment.

[0034] Example 2: This embodiment of the device for reducing the viscosity of viscous clinical molecular test specimens is described. The base 11 of the support assembly 1 is placed on an operating table with a stable support surface. The guide rail 12 is tightly connected to the rear side of the top surface of the base 11 via screws. The material cup 5 is placed in a groove on the front side of the top surface of the base 11. In the linear actuator 2, the rear plate 21 and the front plate 22 engage with the guide rail 12 via rollers 23. The housing surface of the servo motor 24 is fixed to the rear surface of the rear plate 21 via bolts. Its output shaft is connected to a rubber roller 25 via a coupling. The rubber roller 25 is in close contact with the right side surface of the guide rail 12. The support plate 26 on the front side of the front plate 22 is used to secure the tank body 31.

[0035] The ultrasonic stirring viscosity reduction mechanism 3 has a stirring motor 34 and a feed hopper 33 installed on the top of the tank body 31. The stirring motor 34 output shaft is connected to a ribbon stirring paddle 32 to stir the specimen in the tank body 31. The ultrasonic generator 35 is embedded in the left and right side walls of the tank body 31 to cavitate and crush the specimen. The electric heating wire 36 is arranged in a ring array on the inner side wall of the tank body 31 to heat the specimen. The discharge funnel 41 of the material control component 4 is connected to the bottom of the tank body 31 via a flange. The electric control valve 42 controls the discharge, and the guide tube 43 guides the specimen into the material cup 5. During operation, after the specimen is placed in the tank body 31, the stirring motor 34, ultrasonic generator 35 and electric heating wire 36 are started to stir, cavitate and crush, and heat the specimen. The servo motor 24 drives the linear movable drive 2 to move up and down, so that the bottom port of the material control component 4 remains at a position approximately 1.5 cm above the liquid level in the material cup 5. After the treatment is completed, the electronically controlled valve 42 is opened, and the specimen flows into the material holding cup 5 through the guide tube 43 and is mixed with the disinfectant solution for disinfection.

[0036] Example 3: In the support assembly 1 of the viscous clinical molecular test specimen viscosity reduction device, the base 11 is placed on a stable operating table, the guide rail 12 is connected to the rear side of the top surface of the base 11 by screws, and the material cup 5 is placed in the groove on the front side of the top surface of the base 11. The rear and front plates 21 and 22 of the linear actuator 2 move on the guide rail 12 via rollers 23. The servo motor 24 is fixed to the rear side of the rear plate 21. The rubber roller 25 connected to its output shaft contacts the right side surface of the guide rail 12. The support plate 26 on the front side of the front plate 22 is used to fix the tank body 31. The top of the tank body 31 of the ultrasonic agitation viscosity reduction mechanism 3 is equipped with a stirring motor 34 and a feed hopper 33. The stirring motor 34 drives the ribbon stirring paddle 32 to stir the specimen. Ultrasonic generators 35 are embedded on the left and right sides of the tank body 31 to cavitate and fragment the specimen, and electric heating wires 36 on the side walls of the inner cavity heat the specimen. The discharge funnel 41 of the material control component 4 is connected to the bottom of the tank body 31 through a flange, the electric control valve 42 controls the discharge, and the guide tube 43 guides the specimen into the material cup 5. During operation, the specimen is placed in the tank body 31, and the stirring motor 34, ultrasonic generator 35 and electric heating wire 36 are started to stir, cavitate and crush the specimen, and heat it. The servo motor 24 drives the linear movable drive part 2 to move up and down, so that the bottom port of the material control component 4 is 1.8 cm above the liquid level in the material cup 5. After the processing is completed, the electric control valve 42 is opened, and the specimen flows into the material cup 5 through the guide tube 43 and is mixed with the disinfectant solution for disinfection.

[0037] Based on the content of the preferred technical solution described above, the workflow of this technical solution is explained as follows: Place the device on a stable and suitable operating table, firmly place the base 11 of the bracket assembly 1, tightly lock and connect the bottom end of the guide rail 12 to the rear side of the top surface of the base 11 with screws, and place the material cup 5 in the groove opened on the front side of the top surface of the base 11 to ensure the stability of the material cup 5. Next, the viscous clinical molecular test specimen is placed into the tank body 31 through the fixed feed hopper 33 on the top surface of the tank body 31 of the ultrasonic stirring and viscosity reduction mechanism 3. At this time, the stirring motor 34 fixed on the top surface of the tank body 31 starts to work, and its output shaft drives the ribbon stirring paddle 32 to rotate in the tank body 31 through the coupling to stir the put-in specimen. At the same time, two ultrasonic generators 35 fixed on the left and right side walls of the tank body 31 are started, and their ultrasonic transmitting ends are directed towards the viscous clinical molecular test specimen inside the tank body 31. The specimen is cavitated and broken by the cavitation effect of the ultrasonic wave, thereby further reducing the viscosity of the specimen.

[0038] In addition, several electric heating wires 36 fixed to the inner sidewall of the tank 31, arranged in a circular array with the axis of the tank 31 as the base point, begin to heat, heating the viscous clinical molecular test specimen inside the tank 31. This heat changes the physical properties of the specimen and helps reduce its viscosity. During the stirring, cavitation fragmentation, and heat treatment of the specimen, the linear movable drive 2 begins to operate. The servo motor 24 fixed to the right side of the rear surface of the rear side plate 21 is activated. Its output shaft drives the rubber roller 25 in contact with the right side surface of the guide rail 12 through a coupling. Because four rollers 23 are installed at the four corners between the rear side plate 21 and the front side plate 22, and a circular hole is opened inside the support plate 26 fixed to the front surface of the front side plate 22 for the tank 31 to pass through and fix, the entire ultrasonic stirring and viscosity reduction mechanism 3 and the material control assembly 4 can move up and down along the guide rail 12 with the linear movable drive 2. By controlling the rotation of the servo motor 24, the bottom port of the material control component 4 is always located 1.0 cm to 2.0 cm above the liquid level in the material cup 5. This can avoid liquid splashing due to the bottom port of the material control component 4 being too high during the subsequent discharge process.

[0039] After the specimen has undergone a period of stirring, cavitation, and heating within the tank 31, achieving the desired viscosity reduction effect, the electrically controlled valve 42, fixed to the bottom port of the discharge funnel 41 in the material control assembly 4, is opened. The viscosity-reduced specimen within the tank 31 then passes sequentially through the discharge funnel 41, electrically controlled valve 42, and a flow guide 43 fixed to the discharge port of the electrically controlled valve 42, ultimately flowing into the holding cup 5 located directly below the flow guide 43. A disinfectant solution is pre-placed within the holding cup 5. The viscous clinical molecular test specimen, after viscosity reduction, is mixed with the disinfectant solution, thereby disinfecting the specimen and completing the entire viscosity reduction and subsequent processing process for the viscous clinical molecular test specimen.

[0040] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the guidance of the present invention, and any technical solutions that are the same or similar to those of the present invention, fall within the scope of protection of the present invention. Finally, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented.
