Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for stem cells. Background Art

[0002] Stem cells are a type of multipotent cells with the ability to self-replicate. Under certain conditions, they can differentiate into a variety of functional cells. Therefore, in obstetric medicine, the use of stem cell differentiation ability to treat patients has been widely used. Stem cell therapy usually requires sampling from the body's fat cell tissue. After the fat cell tissue can be extracted from the subcutaneous fat layer of the human body, it needs to go through a series of treatments such as centrifugation and shaking to obtain fat stem cells.

[0003] For example, the utility model patent with Chinese patent publication number CN212894739U discloses a sampling device for stem cells, including a housing, feet are provided on both sides of the bottom end of the housing, a motor is provided on the bottom wall inside the housing, a conical transmission member is provided at the output end of the motor, the output end of the conical transmission member is connected to a fixed bearing located at the upper part of the housing, and a stem cell processing mechanism is connected to the upper part of the fixed bearing;

[0004] It was found during use of the above-mentioned prior art that when the device places a test tube storing stem cells between the clamping plates, the device starts a centrifugal action. When the test tube storing stem cells is placed on an oscillation plate, an oscillation action is performed. In this way, when operating, the experimenter can remove the test tube storing stem cells from the oscillation plate and put it back into the clamping plates for centrifugation. The operation is simple, but the device only relies on the clamping plates and the sleeve pads to fix the test tubes, and the fixing effect is poor, which reduces the work efficiency and leads to poor practicality.

The first motor is started, and the first motor drives the rotating rod to rotate through the engagement of two gears, so that the support plate drives the sampling tube to be centrifuged. This process realizes a process that is easy to fix, improves work efficiency, and thus enhances practicality.

[0010] Preferably, a plurality of the first through holes are each provided with a protective pad.

[0011] By adopting the above technical solution, the protective pad can prevent the top end of the sampling tube from directly contacting the first L-shaped plate or the side plate, thereby enhancing safety.

[0020] The sampling tubes are placed in the multiple first through holes, and the second motor is started. The second motor drives the screw to rotate, and the lifting plate screwed with the screw drives the support plate to descend under the limiting action of the limiting rod until the top plate contacts the multiple test tubes.
