Description

Technical Field

[0001] This utility model belongs to the field of medical testing equipment technology, and in particular relates to a reagent shaking device for laboratory use. Background Technology

[0002] The laboratory is one of the most important medical departments. It uses testing equipment to examine patients' biological samples. Before testing, the biological samples are usually shaken with a shaking device to dissolve the components in the test solution. Then, the test solution containing the sample components is placed into the testing equipment for component analysis.

[0003] Chinese patent application CN221933756U discloses a blood testing vibration device, relating to the field of blood vibration technology. It includes a vibrating seat and a base arranged vertically, as well as a rotating mechanism and a vertical vibration mechanism. The rotating mechanism includes a motor located within the base. A main shaft located below the vibrating seat is vertically fixed to the output end of the motor. A sliding member is symmetrically mounted vertically on the main shaft and symmetrically mounted laterally below the vibrating seat. The sliding member is hinged to the sliding member via a movable connecting rod. The base has a ring platform. With the combined action of the rotating mechanism and the vertical vibration mechanism, the blood sample can be vibrated vertically while simultaneously undergoing a undulating and rotating motion, ensuring thorough vibration and uniform shaking, thus further improving the vibration effect and efficiency of the blood sample.

[0004] The aforementioned blood testing shaking device includes a sample placement seat with a test tube slot inside. An elastic pad is adhered to the inner wall of the test tube slot, providing a locking effect. However, because this shaking device can perform both horizontal and vertical shaking, relying solely on the elastic pad for clamping the test tubes results in extremely limited clamping force, leading to inconsistencies in clamping force for test tubes of different diameters. Furthermore, after the test tubes are inserted into the sample placement seat, the shaking effect is achieved by driving motors one and two. Most sample shaking processes require a certain temperature to accelerate the separation and dissolution of components into the test solution, but this device only uses shaking for separation, resulting in a long separation time. Therefore, we provide a reagent shaking device for laboratory use to solve the above-mentioned problems. Utility Model Content

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model features a fixing component. A test tube slot is provided on the placement plate, and a fixing component is located at the bottom of the test tube slot. The fixing component includes a negative pressure plate embedded in the inner wall of the bottom of the test tube slot. An air tube at the bottom of the negative pressure plate is connected to a negative pressure tube via a solenoid valve. An elastic element is also provided on the upper outer side of the negative pressure plate and on the inner wall of the bottom of the test tube slot. The elastic element includes a fixing ring fixed to the side wall of the bottom of the test tube slot, and the upper side wall of the fixing ring is connected to a rubber ring via a spring. In use, the negative pressure tube is connected to a negative pressure pump in the laboratory via a pipe. Then, the test tubes to be tested are inserted into the test tube slot. The negative pressure pump is started, and the negative pressure generated by the pump is transmitted to the negative pressure tube. Then, the solenoid valve is opened. At this time, the negative pressure tube is connected to the negative pressure plate. When the test tube is inserted into the test tube slot, the bottom wall of the test tube contacts the rubber ring. As a downward force is continuously applied to the test tube, it is pushed down continuously in the test tube slot. At this time, the second spring is continuously compressed until it is fully inserted into the bottom slot, that is, the bottom wall of the rubber ring contacts the bottom wall of the test tube slot. Due to the influence of the negative pressure in the negative pressure plate, a negative pressure adsorption force is generated on the bottom of the test tube, thus fixing the test tube. After the vibration is completed, the solenoid valve closes, at which point the negative pressure in the negative pressure plate disappears, and the pressure on the second spring also disappears. It then pushes the top rubber ring, carrying the test tube upward, so that the vibrated test tube can be removed. This achieves the effect of fixing test tubes with a diameter smaller than the inner diameter of the test tube slot.

[0017] 2. This utility model features a clamping assembly comprising a ring disposed on the upper side wall of a test tube groove. A vertical plate is fixedly mounted on the upper side wall of the ring, and the ring is connected to a mounting ring via the vertical plate. An electric heating plate is embedded in the inner wall of the vertical plate, and a rubber pad is adhered to the inner wall of the mounting ring. In use, the test tube is inserted from the mounting ring into the test tube groove below it. The rubber pad on the inner wall of the mounting ring prevents the test tube from contacting the metal mounting ring, thus protecting the test tube. While the test tube is vibrating, the electric heating plate also operates, generating heat that heats the test tube. This causes the components on the sample inside the test tube to quickly separate and dissolve into the detection solution. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-3 This utility model is a reagent shaking device for laboratory use, including a base 1, a vibration component 2 and a placement plate 3. The vibration component 2 can provide the power for up and down vibration of the placement plate 3, so as to achieve the effect of shaking the test tubes in the placement plate 3.

[0030] Specifically, the base 1 consists of a base plate 101 and a side plate 102. The side plate 102 is welded to both ends of the base plate 101. A sliding groove 102a is also provided on the inner side of the upper middle part of the side plate 102, and a sliding rod 103 is inserted in the sliding groove 102a. Two springs 103a are sleeved on the sliding rod 103. The vibration assembly 2 includes a frame 202 fixed at the center of the base plate 101, and a vibration motor 201 is installed in the frame 202. Side grooves 302 are provided in the side walls at the four corners of the placement plate 3. The outer wall of the corner of the placement plate 3 is separated from the inner wall of the sliding groove 102a. A sliding hole 302a is also provided in the side groove 302, and the sliding hole 302a is used for the sliding connection of the sliding rod 103.

[0031] Furthermore, two springs 103a are respectively disposed on the upper and lower sides of the placement plate 3, and the upper and lower side walls of the placement plate 3 are in contact with the upper and lower inner walls of the slide groove 102a through the springs 103a. Connecting blocks 301 are provided on the left and right side walls of the placement plate 3, and the bottom of the connecting blocks 301 is provided with connecting holes 301a for the shaft mounting of the vibration motor 201. The springs 103a can prevent the placement plate 3 from colliding with the side plate 102 when it vibrates up and down. The slide rod 103 can limit the placement plate 3 to prevent it from detaching from the side plate 102. The springs 103a absorb vibration energy through elastic deformation and reduce rigid impact.

[0032] The operation process of this embodiment is as follows: When the test tube is inserted into the test tube slot 303 of the placement plate 3, the vibration motor 201 is started. Since the motor shaft of the vibration motor 201 is fixedly installed at the bottom of the placement plate 3, it will drive the placement plate 3 to vibrate up and down. The placement plate 3 is used to place the test tube, and the test tube will also vibrate up and down accordingly.

[0033] Example 2

[0034] Please see Figure 4-5Based on embodiment 1, a fixing component 4 is also provided, which can fix test tubes with a diameter smaller than the inner diameter of the test tube groove 303.

[0035] Specifically, the placement plate 3 has test tube slots 303 arranged in a matrix structure. The bottom of the test tube slots 303 has a bottom groove 303b. The test tube slots 303 are also equipped with a fixing component 4. The fixing component 4 includes a negative pressure plate 403 embedded in the inner wall of the bottom of the test tube slots 303. The bottom of the negative pressure plate 403 is also equipped with an air pipe. The air pipe is connected to the negative pressure pipe 401 through a solenoid valve. The negative pressure pipe 401 is connected to the negative pressure pump in the laboratory.

[0036] Furthermore, the bottom groove 303b is formed in an annular structure on the outside of the negative pressure plate 403. An elastic element 404 is provided inside the bottom groove 303b. The elastic element 404 includes a fixing ring 404a fixed inside the bottom groove 303b. The upper side wall of the fixing ring 404a is connected to the rubber ring 404c through a spring 404b. When the spring 404b is compressed, it can be compressed into the bottom groove 303b. At the same time, the bottom side wall of the rubber ring 404c also contacts the bottom inner wall of the test tube groove 303.

[0037] The operation process of this embodiment is as follows: During use, the negative pressure tube 401 is connected to the negative pressure pump in the laboratory via a pipe. Then, the test tube to be tested is inserted into the test tube slot 303. The negative pressure pump is started, and the negative pressure generated by the pump is transmitted to the negative pressure tube 401. Then, the solenoid valve 402 is opened. At this time, the negative pressure tube 401 is connected to the negative pressure plate 403. When the test tube is inserted into the test tube slot 303, the bottom side wall of the test tube contacts the rubber ring 404c. As a downward force is continuously applied to the test tube, it is pushed downwards continuously within the test tube slot 303. Spring 404b is continuously compressed until it is fully inserted into the bottom groove 303b, that is, the bottom side wall of rubber ring 404c contacts the bottom side wall of test tube groove 303. Due to the negative pressure in negative pressure plate 403, a negative pressure adsorption force is generated on the bottom of the test tube, thus fixing the test tube. After the oscillation is completed, solenoid valve 402 closes. At this time, the negative pressure in negative pressure plate 403 disappears, and the pressure on spring 404b also disappears. It then pushes the top rubber ring 404c to move the test tube upward, and the oscillated test tube can be removed.

[0038] Example 3

[0039] Please see Figure 6 Based on Embodiments 1 and 2, a clamping assembly 5 is also provided. The rubber pad 504a in the clamping assembly 5 protects the test tube, and the heating plate 503 heats the test tube.

[0040] Specifically, a rack groove 303a is provided above the test tube groove 303 and in the upper side wall of the placement plate 3. The rack groove 303a is used for the installation of the clamping component 5. The clamping component 5 includes a ring 501 fixed in the rack groove 303a. The ring 501 is connected to the mounting ring 504 through the upright plate 502.

[0041] Furthermore, the mounting ring 504 is positioned directly above the circular ring 501, and multiple vertical plates 502 are arranged in a circular array. The inner wall of the vertical plate 502 has a groove 502a for mounting the heating plate 503. A rubber pad 504a is adhered to the inner wall of the mounting ring 504, and the mounting ring 504 contacts the test tube through the rubber pad 504a. The heating plate 503 is also connected to a temperature control device, which can adjust the heating temperature according to the testing requirements.

[0042] The operation process of this embodiment is as follows: When in use, the test tube is inserted from the mounting ring 504 into the test tube groove 303 below it. Since a rubber pad 504a is provided on the inner wall of the mounting ring 504, the rubber pad 504a can prevent the test tube from contacting the metal mounting ring 504, thus protecting the test tube. While the test tube is being vibrated, the heating plate 503 is also working. When the heating plate 503 is working, it will generate heat, which will heat the test tube.
