Description

Technical Field

[0001] This utility model relates to the technical field of cell grinding equipment, specifically a tissue single-cell humidified grinding device. Background Technology

[0002] Tissue single-cell grinding refers to the process of obtaining single cells from tissue cells through grinding. In existing techniques, the procedure involves placing a cell filter membrane at the mouth of a test tube, placing the tissue cells on top of the membrane, and then the operator holding the grinding rod with the grinding head pressed against the tissue on the filter membrane. With slight pressure and slow rotation of the grinding rod, the tissue cells are ground into single cells. These single cells then pass through the filter membrane and fall into the test tube, thus completing the single-cell acquisition. Clearly, this process is entirely manual, and the applied force and grinding motion vary from person to person, resulting in poor grinding stability and low efficiency.

[0003] Furthermore, because it is necessary to keep the tissue cells moist during the grinding process, in existing technologies, operators need to periodically add water or other wetting liquids to the cell filter membrane to maintain the moisture state of the tissue cells on the filter membrane. However, this manual addition of wetting liquid not only affects grinding efficiency but also adds extra steps for the operator during the grinding process, causing inconvenience to the grinding operation. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art: to provide a tissue single-cell humidifying grinder that can automatically grind tissue cells on a cell filter membrane, resulting in good grinding stability and high efficiency. At the same time, it can automatically add wetting liquid during the grinding process, eliminating the need for operators to manually add wetting liquid and saving labor costs.

[0005] Therefore, one objective of this utility model is to provide a tissue single-cell humidifying grinder, comprising a base, a vertical rod on the base, and a test tube holder on the vertical rod. The test tube holder has at least one test tube slot for placing test tubes. The vertical rod is characterized by having a top support and a lifting mechanism for driving the top support to rise or fall. The top support is located above the test tube holder, and grinding rods are positioned at positions corresponding to each test tube slot. The top support is equipped with a driver for rotating each grinding rod around its own axis. The lower end of each grinding rod has a grinding head, and the outer wall of the grinding head has a small hole for adding wetting liquid to the cell filter membrane placed on the test tube opening. The interior of the grinding rod has a liquid supply channel communicating with the small hole. The base is equipped with a liquid supply device, the water outlet of which is connected to the liquid supply channel inside the grinding rod via a liquid supply hose.

[0006] A lifting mechanism lowers the grinding rod, bringing its lower end against the tissue cells on the cell filter membrane. A driver then rotates the grinding rod steadily, automatically grinding the tissue cells. Single cells separated from the tissue cells pass through the cell filter membrane and fall into a test tube, eliminating the need for manual grinding. Additionally, a liquid supply device pumps a wetting liquid, which enters the supply channel within the grinding rod through a supply hose. The liquid then flows out through small holes on the grinding head, ultimately flowing along the outer wall of the grinding head to the cell filter membrane, completing the wetting of the tissue cells during the grinding process.

[0007] According to an example of this utility model, the upright is a hollow tubular structure, the top support includes a main rod and a horizontal plate arranged on the main rod, each grinding rod is installed on the horizontal plate, the upper end of the upright is sleeved on the main rod, and the lifting mechanism is an electric push rod, the two ends of the electric push rod are respectively connected to the upright and the main rod.

[0008] According to one example of the present invention, the horizontal plate has a device mounting cavity, and a connecting hose is provided in the device mounting cavity. The upper end of the liquid supply hose is connected to one end of the connecting hose, and the other end of the connecting hose is connected to the upper end of the liquid supply channel.

[0009] According to an example of the present invention, the horizontal plate has a plurality of connectors that rotate with the horizontal plate, the driver is mounted on the horizontal plate and the output end of the driver is connected to each connector in a transmission manner, so that the driver can drive each connector to rotate, the upper end of the grinding rod is detachably connected to the lower end of the corresponding connector, the connector has a connecting pipe inside, and the liquid supply channel, the connecting pipe, the connecting hose and the liquid supply hose are connected in sequence.

[0010] According to one example of the present invention, the test tube holder is slidably coupled with the upright so that the position of the test tube holder is adjustable along the height direction.

[0011] According to one example of this utility model, a heating water tank is provided on the base below the test tube holder. The top of the heating water tank has slots corresponding to the positions of each test tube slot, and the bottom of the test tubes is inserted into their respective slots. Since the bottom of the test tubes is inserted into the slots of the heating water tank, the slots can heat the test tubes, maintaining a relatively ideal temperature for the entire test tube, thus ensuring that the single cells that fall into the test tubes after grinding are in a constant temperature environment.

[0012] According to one example of the present invention, the heating water tank has a recessed temporary storage slot located near the front side of the slot, for placing empty test tubes or test tubes after grinding.

[0013] According to one example of the present invention, the opening of the temporary storage tank faces upward and is inclined in the front direction toward the location of the heating water tank.

[0014] According to one example of the present invention, the temporary storage slot is a long strip structure extending along the width direction.

[0015] According to one example of the present invention, the temporary storage slot is a circular hole-shaped groove with a diameter matching the outer diameter of the test tube. There are multiple temporary storage slots, which are spaced apart along the left and right directions of the base.

[0016] The above technical solution has the following advantages or beneficial effects: First, the top support can drive the grinding rod to rise or fall, and the driver can drive the grinding rod to rotate, thereby completing the automatic grinding of tissue cells on the cell filter membrane; second, during the grinding process, the liquid supply device can pump the wetting liquid into the liquid supply channel of the grinding rod, and finally flow out through the small hole on the side wall of the grinding head, realizing the wetting of tissue cells on the cell filter membrane, eliminating the need for manual addition of wetting liquid; third, the upper end of the grinding rod is detachably connected to the connector, thereby facilitating grinding. The test tube holder can be adjusted vertically, allowing the bottom of the test tube to be inserted into the slot on the heating water tank, providing a grinding temperature higher than the constant temperature. Finally, the added temporary storage slot not only holds empty test tubes for easy replacement of ground test tubes on the test tube holder, but also allows ground test tubes to be temporarily stored. Furthermore, the temporary storage slot, located on the heating water tank, continuously heats the test tubes, ensuring the cells inside remain at a constant temperature.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] The tissue single-cell humidifying grinder according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] This invention provides a tissue single-cell humidified grinder, as shown in the figure. It includes a base 1, a vertical rod 2, a test tube holder 3, a top support 5, a grinding rod 7, and a driver 8. The vertical rod 2 stands on the base 1, and its lower end is fixed to the base 1. The test tube holder 3 is mounted on the vertical rod 2, and the test tube holder 3 has at least one test tube slot 4 for placing each test tube 18. Each test tube slot 4 is positioned along... Figure 3The test tube holders 3 are spaced apart in a left-right direction. A top support 5 is located above the test tube holder 3, and a lifting mechanism 6 is provided on the upright 2 to drive the top support 5 up and down. One or more grinding rods 7 are shown, the number of which matches the number of test tube slots 4. The grinding rods 7 are mounted on the top support 5, and each grinding rod 7 is located above its corresponding test tube slot 4. The lower end of each grinding rod 7 has a grinding head 7.1 facing the corresponding test tube slot 4. When the grinding rod 7 descends with the top support 5 to the working position, the grinding head 7.1 on the grinding rod 7 abuts against the cell filter membrane 19 on the corresponding test tube opening. A driver 8 is provided on the top support 5 to drive each grinding rod 7 to rotate around its own axis.

[0030] Preferably, there are six grinding rods 7.

[0031] The test tube support 3 in the above embodiment is along Figure 3 The test tube support 3 has a long strip structure extending from left to right. Holes are drilled along the height direction to form a test tube groove 4. The outer diameter of the test tube 18 is equal to or slightly smaller than the inner diameter of the test tube groove 4. The width of the opening of the test tube 18 is greater than the inner diameter of the test tube groove 4, so that the test tube 18 can be stuck on the test tube groove 4 at the opening.

[0032] On the other hand, since test tubes 18 come in several different diameters when inserted into the test tube slot 4, in order to ensure that test tubes 18 of different diameters can be properly placed on the test tube slot 4, a preferred improvement to the test tube slot 4 on the test tube support 3 in the above embodiment is made as follows: Figure 5 As shown, the test tube groove 4 has a circular hole, and a detachable tube sleeve 21 is nested on the test tube groove 4. The upper end of the tube sleeve 21 has a flange that flares outward in the horizontal direction. The outer diameter of the tube sleeve 21 matches the inner diameter of the test tube groove 4, and the inner diameter of the tube sleeve 21 matches the outer diameter of the test tube 18. In this embodiment, by replacing tube sleeves 21 of different sizes, the inner diameter of different tube sleeves 21 can match test tubes 18 of different sizes.

[0033] In the above embodiments, as the grinding process proceeds, the tissue cells on the cell filter membrane 19 continuously lose moisture. To keep the cell filter membrane 19 and the tissue cells on it moist, it is necessary to manually add a wetting liquid, such as water, periodically. Therefore, to automate this process of adding the wetting liquid and eliminate the inconvenience of manual addition, the improvement of this embodiment is as follows: Figure 5As shown, the outer wall of the grinding head 7.1 has multiple small holes 7.2, which are evenly arranged around the circumference of the grinding head 7.1. The wetting liquid flows out through the small holes 7.2 and can flow downward along the outer surface of the grinding head 7.1 under its own gravity. It is used to add wetting liquid to the cell filter membrane 19 placed on the mouth of the test tube 18. The grinding rod 7 has a liquid supply channel 7.3 that communicates with the small holes 7.2. The base 1 is equipped with a liquid supply device. The water outlet of the liquid supply device is connected to the liquid supply channel 7.3 inside the grinding rod 7 through a liquid supply hose 16.

[0034] Preferably, the liquid supply device is a water pump 15, and the outlet of the water pump 15 is connected to the liquid supply channel 7.3 through a liquid supply hose 16. Further, the water pump 15 is a water pump 15 with a heating function. This water pump 15 with a heating function is a conventional commercially available product in the prior art, and its structure and model will not be described in detail.

[0035] like Figure 7 As shown, the upright 2 is a hollow tubular structure. The top support 5 includes a main rod 5.1 and a horizontal plate 5.2 arranged transversely on the main rod 5.1. The upper end of the main rod 5.1 is fixed at the middle position of the horizontal plate 5.2, and the lower end of the main rod 5.1 is inserted into the upper end of the upright 2, thereby connecting the upper end of the upright 2 and the lower end of the main rod 5.1. Each grinding rod 7 is installed on the horizontal plate 5.2 and aligned with its corresponding test tube groove 4. The lifting mechanism 6 is an electric actuator, with both ends connected to the upright 2 and the main rod 5.1, respectively. Thus, the extension and retraction of the electric actuator drives the main rod 5.1 to move up and down in the height direction. The base 1 is equipped with a controller that communicates with the electric actuator.

[0036] Based on the preferred embodiment described above, the horizontal plate 5.2 has a device mounting cavity 5.4, and a connecting hose 17 is provided in the device mounting cavity 5.4. The upper end of the liquid supply hose 16 is connected to one end of the connecting hose 17, and the other end of the connecting hose 17 is connected to the upper end of the liquid supply channel 7.3.

[0037] Based on the preferred embodiment described above, the horizontal plate 5.2 has a plurality of connectors 5.3 that rotatably engage with the horizontal plate 5.2. The number of connectors 5.3, grinding rods 7, and test tube slots 4 are the same, and each connector 5.3, each grinding rod 7, and each test tube slot 4 corresponds one-to-one in the vertical direction. The driver 8 is mounted on the horizontal plate 5.2, and the output end of the driver 8 is connected to each connector 5.3 for transmission, so that the driver 8 can drive each connector 5.3 to rotate. The upper end of the grinding rod 7 is detachably connected to the lower end of the corresponding connector 5.3. The connector 5.3 has a connecting pipe 5.3.1 inside, and the liquid supply channel 7.3, the connecting pipe 5.3.1, the connecting hose 17, and the liquid supply hose 16 are sequentially connected. It should be understood that since the connector 5.3 is rotatable, while the connecting hose 17 located inside the horizontal plate 5.2 is stationary, the end of the connecting hose 17 is connected to the upper end of the connector 5.3 through a rotatable rotary joint 17.1.

[0038] Preferably, such as Figure 7 As shown, the driver 8 includes a drive motor 11 and a transmission belt 12. The drive motor 11 is fixed inside the horizontal plate 5.2 of the top bracket 5. A drive wheel 13 is provided on the output shaft of the drive motor 11. Each connector 5.3 has a driven wheel 14 at its upper end. The drive wheel 13 and each driven wheel 14 are connected by the transmission belt 12. The connecting pipe 5.3.1 in the connector 5.3 passes vertically through the upper end of the driven wheel 14. The rotary joint 17.1 is installed on the port of the connecting pipe 5.3.1 of the driven wheel 14 and rotates with the driven wheel 14. The end of the connecting hose 17 is connected to the connecting pipe 5.3.1 in the driven wheel 14 through the rotary joint 17.1. It should be understood that when there is a single grinding rod 7, there is also a corresponding driven wheel 14. In this case, the drive wheel 13 and the driven wheel 14 can be directly driven by the transmission belt. When there are multiple grinding rods 7, the number of driven wheels 14 also increases accordingly. Figure 7As shown, with only one drive wheel 13, it is necessary to ensure that the drive wheel 13 drives multiple driven wheels 14 to rotate synchronously. This means the annular transmission belt needs to sequentially pass over the drive wheel 13 and each driven wheel 14. Therefore, it is necessary to consider increasing the wrap angle between the belt drive and the drive wheel and each driven wheel to ensure stable synchronous linkage between the belt and these wheels. One approach is to use a looping method, where the belt passes around the left side of the first driven wheel and then the right side of the second driven wheel, and so on, increasing the wrap angle. Another approach is to add several tensioners to change the direction of the belt on the drive wheel and each driven wheel, thereby changing the wrap angle and increasing the wrap angle. Since belt drives are a conventional transmission method in the field of mechanical transmission, adding tensioners to increase the wrap angle is common knowledge in this art. Therefore, the installation positions of the tensioners will not be described in detail in this embodiment.

[0039] Furthermore, the transmission belt is a synchronous belt with teeth on one side, and the drive wheel and each driven wheel are provided with tooth grooves that match the teeth on the synchronous belt, thereby reducing the slippage between the synchronous belt and the drive wheel and each driven wheel.

[0040] Of course, based on the preferred embodiment described above, the driver 8 includes a plurality of drive motors 11, the number of drive motors 11 matching the number of grinding rods 7, and each drive motor 11 is used to drive its corresponding connector 5.3 to rotate.

[0041] The lower end of the connector 5.3 is provided with a slot, the slot opening is horizontal, and the slot matches the flange at the upper end of the grinding rod 7, allowing the grinding rod 7 to be inserted into the slot horizontally. When the upper end of the grinding rod 7 is engaged with the slot, the grinding rod 7 is confined within the slot in the height direction, and the connector 5.3 and the grinding rod 7 are circumferentially confined, so that the connector 5.3 can drive the grinding rod 7 to rotate synchronously in the circumferential direction.

[0042] Based on the improvement of the above embodiments: the test tube support 3 is slidably engaged with the upright 2 so that the position of the test tube support 3 along the height direction is adjustable.

[0043] Specifically, such as Figure 1 and Figure 7 As shown, the test tube holder 3 has an assembly hole at the middle position along the left-right direction. This assembly hole fits over the upright 2. The test tube holder 3 is equipped with a locking component, which has an open state and a locked state. When the locking component is in the open state, the test tube holder 3 can be adjusted arbitrarily along the height direction. When the locking component is in the locked state, the locking component is fastened to the side wall of the upright 2, thus fixing the test tube holder 3 to the upright 2. Preferably, the locking component is a locking bolt.

[0044] like Figure 5 As shown, in the above embodiment, the cell filter membrane 19 is also called a cell sieve. The cell filter membrane 19 has a bowl-shaped structure with the opening facing upward, and the upper edge of the cell filter membrane 19 has a flange extending outward in the horizontal direction. Tissue cells can be placed inside the bowl-shaped cell filter membrane 19 from top to bottom. Due to the porous structure of the cell filter membrane 19, during the process of grinding tissue cells by the grinding rod 7, the separated single cells can pass through the cell filter membrane 19 and finally be recorded into the test tube 18 below the cell filter membrane 19.

[0045] During the process of grinding to obtain single cells, the temperature of the test tube 18 is affected by the external environment after the single cells fall into the test tube 18. Changes in the ambient temperature will affect the cells. In order to ensure that the single cells obtained after grinding the tissue cells can maintain a good biological state, the improvement of this embodiment is that: a heating water tank 9 is provided on the base 1, and a slot 10 is provided on the top of the heating water tank 9 below each test tube slot 4, and the bottom of the test tube 18 is located in the slot 10.

[0046] Furthermore, the heating water tank 9 has a recessed temporary storage groove 20 located on the slot 10 near the front side of the heating water tank 9, for placing empty test tubes 18 or test tubes 18 after grinding. In this embodiment, the front side of the heating water tank 9 in the front-back direction refers to the front-back direction, that is... Figure 3 In front of the vertical paper, the operator stands near the front of the heating water tank 9 for easy operation of the test tubes. The width of the temporary storage slot 20 is set to allow the body of the test tube 18 to be inserted into the temporary storage slot 20. The flared end of the test tube 18 is located outside the temporary storage slot 20. Thus, the temporary storage slot 20 can not only be used to place spare empty test tubes 18, but also to temporarily place the ground test tubes on the test tube support 3 into the temporary storage slot 20 after they have been ground, serving as a temporary resting place for the test tubes 18. During this process, the heating water tank 9 can continuously provide heat to maintain the temperature of the test tubes 18 when they are temporarily placed after being removed from the test tube support 3.

[0047] In a preferred embodiment of the above, the opening of the temporary storage tank 20 faces upward and is inclined toward the front side of the heating water tank 9 in the front-back direction.

[0048] Based on one of the preferred examples of the temporary storage slot 20 in the above embodiments: such as Figure 1 and Figure 6 As shown, the temporary storage slot 20 is a long strip structure extending along the width direction, that is, along... Figure 6 It extends in a long strip shape in the left and right directions.

[0049] To prevent collisions between test tubes, preferably, the temporary storage tank 20 has multiple positioning grooves 20.1 on its inner wall near the front of the heating water tank 9. These positioning grooves 20.1 are arranged sequentially at intervals along the left-right direction, and each positioning groove 20.1 is configured as an arc-shaped structure that matches the outer wall of the test tube 18. After the bottom of the test tube 18 is inserted into the temporary storage tank 20, the test tube 18 will be confined within the corresponding positioning groove 20.1, preventing the test tube 18 from moving in the left-right direction.

[0050] A second preferred embodiment of the temporary storage slot 20 described above: The temporary storage slot 20 is a circular groove with a diameter matching the outer diameter of the test tube 18. Multiple temporary storage slots 20 are spaced apart along the left-right direction of the base 1. A test tube 18 is inserted into a corresponding temporary storage slot 20, which can hold empty test tubes and also temporarily store test tubes that have been ground and have yielded single cells. During this process, the heating water tank 9 can heat the test tube 18 through the temporary storage slot 20, providing a constant temperature environment.

[0051] Preferably, the inner walls of the slot 10 and the temporary storage tank 20 in the heating water tank 9 are thin-walled structures, so that the temperature of the heating water tank 9 can be better transferred to the slot 10 and the temporary storage tank 20 for heating the test tubes in the slot 10 and the temporary storage tank 20.

[0052] The heating water tank 9 can be a hot water tank with an insulation layer on its outer wall, so that the hot water stored in the tank can continuously provide heat to the slot 10. The heating water tank 9 can also be a hot water tank with a heater. When the heater is powered on, it heats the water in the tank, and the resulting hot water maintains a constant temperature in the slot 10 through heat transfer.

[0053] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0054] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
