Description

Technical Field

[0001] The utility model relates to the technical field of biological research tools, in particular to a biological cell extraction device for biological research. Background Art

[0002] Biological cells are a type of cells that have unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. In the process of studying biological cells, it is necessary to extract the biological cells through an extraction device and extract the biological cells into a culture dish or observe them under a microscope to facilitate the cultivation and research of the biological cells.

[0003] For example, the utility model: "A biological cell extraction device for biological research", with the announcement number: "CN213835332U", can protect the device through the provision of a first protective shell and a first Velcro, thereby preventing the device from colliding and being easily damaged, thereby improving the practical effect of the device, and the provision of a filter, a chute and a pulley can filter the device, thereby preventing the device from being easily damaged. However, during the implementation of the patent, although the protective shell can protect the needle, the needle cannot be sealed inside the protective shell. When there is dust inside the protective shell, the dust can still enter the needle, and when the device extracts biological cells, it cannot chop up large pieces of biological cell tissue, thereby making it inconvenient to extract biological cells.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an embodiment: a biological cell extraction device for biological research, including a mounting plate 3, a biological cell extraction tube 4 and a suction tube 14, wherein the suction tube 14 is installed at the middle position of the bottom of the biological cell extraction tube 4, and a rubber plug 13 is installed inside the biological cell extraction tube 4, and a pull rod 5 is installed at the middle position of the top of the rubber plug 13, mounting plates 3 are installed at the bottom of both ends of the biological cell extraction tube 4, and mounting circular holes 11 are provided inside the mounting plates 3, mounting rods 2 are installed inside the mounting circular holes 11, and a fixing plate 10 is installed at one end of the fixing rod 2 close to the suction tube 14, and a sealing baffle 7 is installed at the bottom of the fixing plate 10.

[0022] In this implementation:

[0023] Furthermore, a filter screen 9 is installed inside the suction tube 14 to prevent impurities from being sucked into the suction tube 14 when extracting biological cells.

[0024] Furthermore, the pull rod 5 passes through the biological cell extraction tube 4 and extends to the outside of the biological cell extraction tube 4, and a push-pull plate 12 is installed on the top of the pull rod 5. The staff can pull the pull rod 5 upward through the push-pull plate 12, so that the pull rod 5 pulls the rubber plug 13 to move upward, and the biological cells can be sucked into the biological cell extraction tube 4 through the suction tube 14.

[0025] Furthermore, a connecting plate 1 is installed at one end of the mounting rod 2 away from the fixed plate 10, and a reset spring 15 is installed on the top of the connecting plate 1 close to the end of the biological cell extraction tube 4. The end of the reset spring 15 away from the connecting plate 1 is connected to the biological cell extraction tube 4. The elastic action of the reset spring 15 causes it to pull the connecting plate 1 to move and reset. The connecting plate 1 drives the fixed plate 10 to move through the mounting rod 2, so that the fixed plate 10 drives the sealing baffle 7 to move. The sealing baffle 7 can be used to block the pipe mouth position of the suction pipe 14, so that the suction pipe 14 can be sealed to prevent external dust and liquid from entering the suction pipe 14, thereby avoiding contamination of the biological cells.

[0026] Furthermore, a pull ring 16 is installed at one end of the connecting plate 1 away from the biological cell extraction tube 4, so that the staff can pull the connecting plate 1 to move.

[0027] Furthermore, a non-slip rubber ring 6 is installed on the outside of the biological cell extraction tube 4 , and non-slip protrusions are evenly arranged on the outside of the non-slip rubber ring 6 , which has a good non-slip effect and is convenient for the staff to hold the biological cell extraction tube 4 .

[0028] Furthermore, a cutting blade 8 is installed at the bottom of the sealing baffle 7. Before extracting biological cells, the sealing baffle 7 can drive the cutting blade 8 to move, and large pieces of biological cell tissue can be cut into small pieces by two sets of cutting blades 8, thereby facilitating the extraction of biological cells into the biological cell extraction tube 4.

[0029] Working principle:

[0030] When in use, the staff can hold the biological cell extraction tube 4 with one hand through the anti-slip rubber ring 6, and can pull the pull ring 16 with two fingers of the other hand, and the pull ring 16 drives the connecting plate 1 to move together, so that the connecting plate 1 stretches the reset spring 15, and the connecting plate 1 drives the fixing plate 10 to move through the mounting rod 2, so that the fixing plate 10 drives the sealing baffle 7 to move, and the sealing baffle 7 can be moved away from the pipe opening position of the suction pipe 14;

[0031] When the biological cell tissue needs to be shredded, the staff puts the biological cell tissue between the two sets of cutting blades 8, and then the staff loosens the pull ring 16. At this time, the elastic action of the reset spring 15 causes it to pull the connecting plate 1 to move and reset, and the connecting plate 1 drives the fixing plate 10 to move through the mounting rod 2, so that the fixing plate 10 drives the sealing baffle 7 to move, and the sealing baffle 7 drives the cutting blades 8 to move, so that the two sets of cutting blades 8 squeeze the biological cell tissue, and the biological cell tissue can be shredded by the two sets of cutting blades 8;

[0032] When extracting biological cells, the staff can pull the pull ring 16 again to move the two sets of sealing baffles 7 away from the tube mouth of the suction tube 14, and then place the suction tube 14 at the biological cell position. The staff can pull the pull rod 5 upward through the push-pull plate 12, so that the pull rod 5 pulls the rubber stopper 13 upward, and the biological cells can be sucked into the biological cell extraction tube 4 through the suction tube 14;

[0033] After the extraction is completed, the staff releases the pull ring 16 so that the sealing baffle 7 is again covered at the tube mouth of the suction tube 14, and the suction tube 14 can be sealed, which not only prevents external dust and liquid from entering the suction tube 14, thereby avoiding contamination of the biological cells, but also prevents the biological cells inside the biological cell extraction tube 4 from leaking through the suction tube 14.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
