Description

Technical Field

[0001] The utility model belongs to the technical field of tissue grinding, in particular to a novel tissue grinder. Background Art

[0002] Tissue grinding is an essential process for genome extraction or isolation of microbial pathogens. Currently, most laboratories use manual grinding, electric tissue grinders, and handheld electric homogenizers for grinding.

[0003] Traditional manual grinding is not only time-consuming and laborious, but the grinding vessels, such as mortars or glass homogenizers, are open, easily contaminated, and difficult to clean. Electric tissue grinders offer good grinding results, but the equipment is expensive and unsuitable for small laboratories. Handheld electric homogenizers often use the shear force generated by the rotation of the rotor to shred tissue. While labor-saving, the foam generated during rotation can easily overflow the centrifuge tube, causing contamination. To address the high cost and contamination issues of existing tissue grinders, the present invention provides a new tissue grinder. Utility Model Content

[0033] Example

[0034] Reference Figure 1-2 As shown, a novel tissue grinder comprises a housing 1, an inner liner tube 2, at least one rubber ring 3, a sample tube 4, a driving device 5 and a grinding rod 6;

[0035] The inner liner tube 2 is fixed to the bottom of the shell 1; at least one rubber ring 3 is fixedly mounted on the inner liner tube 2; the mouth of the sample tube 4 is mounted outside the inner liner tube 2; the driving device 5 is arranged in the shell 1; the grinding rod 6 is located in the sample tube 4, connected to the driving device 5, and is driven by the driving device 5 to reciprocate up and down.

[0036] Specifically, the shell 1 is a rectangular structure, with all four sides fixed by snap-on fixings. It is 5-7 cm long, 5-7 cm high, and 3-4 cm wide. The shell 1 is equipped with batteries, control circuit boards and other components connected to the drive device 5. The shell 1 is equipped with a grinding speed adjustment switch and a power charging port. The inner lining tube 2 has a diameter of 0.7-1.2 cm and a height of 0.5-1 cm. The rubber ring 3 has a diameter of 0.9-1.4 cm. The sample tube 4 is a plastic centrifuge tube commonly used in laboratories.

[0037] When the device is in use, the sample is placed in the sample tube 4, and then the mouth of the sample tube 4 is placed outside the inner liner tube 2. The rubber ring 3 is squeezed and compressed between the sample tube 4 and the inner liner tube 2, so that the sample tube 4 and the inner liner tube 2 are sealed. The driving device 5 is started, and the grinding rod 6 is driven by the driving device 5 to reciprocate up and down to grind the sample in the sample tube 4.

[0038] The device has a simple structure, is easy to operate, and has a low overall cost. It is very suitable for small laboratories. The grinding rod 6 is driven by the driving device 5 to move up and down to grind the sample. The height of the sample overflowing is relatively low, and the sample tube 4 and the inner liner tube 2 are sealed by the rubber ring 3, which can further prevent the sample from overflowing from the mouth of the sample tube 4, and the sample is not easily contaminated.

[0039] In a specific embodiment, the driving device 5 includes a support plate 51, a motor 52, a turntable 53, a matching column 54, a limit buckle 55 and a connecting piece 56;

[0040] The support plate 51 is fixed in the shell 1; the motor 52 is fixed on the top of the support plate 51; the turntable 53 is located on the side of the support plate 51, and its center is fixedly connected to the output shaft of the motor 52; the matching column 54 is fixed on the edge of the turntable 53; the limiting buckle 55 is fixed on the side of the support plate 51; the connecting member 56 includes a connecting rod 561 and a matching block 562, the connecting rod 561 is movably inserted into the limiting buckle 55, the bottom of which passes through the shell 1 and is fixedly connected to the grinding rod 6, and the top is fixedly connected to the matching block 562, and a transverse slot 563 is provided in the matching block 562, and the transverse slot 563 is slidably matched with the matching column 54.

[0041] The connecting rod 561 is made of antibacterial and rust-proof material, and adopts an adjustable length threaded hollow structure with a telescopic length of 1-3 cm. The limit buckle 55 limits the connecting rod 561 so that the connecting rod 561 can only move up and down. After the motor 52 is started, it drives the turntable 53 to rotate, and the matching column 54 on the turntable 53 cooperates with the horizontal slot 563 on the matching block 562. Under the limiting action of the limit buckle 55, when the turntable 53 rotates, the matching column 54 slides in the horizontal slot 563 while driving the matching block 562 to move up and down, thereby driving the grinding rod 6 to reciprocate up and down through the connecting rod 561 to grind the sample.

[0042] In a specific embodiment, the end of the engagement post 54 away from the turntable 53 is a frustum structure to prevent the engagement post 54 from being separated from the engagement block 562 .

[0043] In a specific embodiment, the connecting rod 561 is connected to the grinding rod 6 via a rubber joint 7, which facilitates the replacement of sample tubes 4 and grinding rods 6 of different specifications.

[0044] In a specific embodiment, the bottom of the grinding rod 6 is a frosted structure to improve the grinding effect.

[0045] In a specific embodiment, a suction cup is provided on the back of the housing 1, which can be adsorbed and fixed in a suitable position during operation.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
