Description

Technical Field

[0001] The utility model relates to the technical field of stem cell preparation, in particular to a portable extraction device for stem cell preparation. Background Art

[0002] Stem cells are cells of origin; in simple terms, they are a type of primitive undifferentiated cells with multidirectional differentiation potential and self-replication ability. They are the original cells that form various tissues and organs of mammals. Stem cells have common morphology, usually round or oval, small cell size, relatively large nucleus, mostly euchromatin, and high telomerase activity. Stem cells can be divided into embryonic stem cells and adult stem cells. When preparing stem cells, it is often necessary to use an extraction device to extract and transport stem cells;

[0003] The patent with the existing authorization announcement number "CN220149568U" discloses an extraction device and a stem cell preparation device, which can squeeze the suction tube to allow the stem cells to pass through the suction tube and then to the box tube to reach the preparation box, so as to achieve the preparation and extraction of stem cells. After the operation is completed, the sealing cover and the suction tube can be removed by separating the clamp from the sealing cover. The clamping method is convenient for disassembling and installing the sealing cover and the suction tube. Through the function of the sterile box, it is convenient to put the suction tube into it, so as to protect the suction tube and avoid it from contacting with the outside world and causing pollution. When the suction tube is drawn out of the sterile box, the sealing member can play a sealing role, so as to cover the opening of the sterile box, thereby preventing the suction tube from contacting with the outside world and causing pollution when not in use. At the same time, it is convenient to disassemble the suction tube, thereby improving practicality.

[0025] Adjustment grooves 18 are provided at both ends of the top of the bracket 1, and adjustment rods 17 are sleeved on the inner sides of the two groups of adjustment grooves 18. A top plate 7 is commonly provided on the tops of the two groups of adjustment rods 17, and a handle is provided in the middle of one side of the top of the top plate 7 to facilitate the movement of the device by carrying or pulling the handle. Moving wheels 12 are provided at both ends of the bottom of one side of the bracket 1, and an adjustment component is provided on the top of the inner side of the bracket 1.

[0026] Furthermore, the adjustment assembly includes a winding wheel 13, an empty slot 14, a connecting rope 15, a guide hole 16, an insertion rod 19, a spring 20 and a slot 21. The top of the inner side of the bracket 1 is provided with an empty slot 14, and one side of the inner side of the empty slot 14 is sleeved with the winding wheel 13. One side of the winding wheel 13 extends to the outer side of the empty slot 14 and is provided with a knob. The winding wheel 13 is conveniently rotated by the knob for adjustment. A plurality of slots 21 are evenly provided at one end of the two groups of adjustment rods 17 close to each other. A guide hole 16 is provided at the top of one end of the inner side of the group of adjusting grooves 18, and an insertion rod 19 matching the slot 21 is slidably inserted into the inner side of the two groups of guide holes 16. Connecting ropes 15 connected to the insertion rod 19 are provided at both ends of the winding wheel 13, and a spring 20 is provided at one end of the two groups of insertion rods 19. When the device is carried, the winding wheel 13 can be rotated to pull the insertion rod 19 out of the slot 21, thereby releasing the fixation of the adjusting rod 17 and adjusting the height of the top plate 7.

[0027] Furthermore, a guide hole matching with the extraction tube 9 is provided in the middle of one inner side of the bracket 1 near the top of the baffle 8, so as to guide the extraction tube 9 so as to move along the guide hole.

[0028] Working principle: When the device is in use, the handle can be used to directly carry the device and move it. At the same time, the bracket 1 can be tilted so that the moving wheel 12 contacts the ground. At this time, the handle can be used to pull the device to roll along the ground. When different users carry the device, the height of the top plate 7 can be adjusted according to needs. When adjusting, the winding wheel 13 can be turned by the knob, and then the winding wheel 13 can be pulled out of the slot 21 by pulling the plug rod 19 through the connection of the connecting rope 15 to overcome the elastic force of the spring 20. At this time, the top plate 7 can be pulled up to adjust the top plate 7 to a suitable height, and then the knob can be loosened. The elastic force of the spring 20 can be used to push the plug rod 19 to be inserted into the corresponding slot 21 to fix the top plate 7. The adjustment is very convenient. After the adjustment is completed, it is more convenient to move the device by pulling the handle.

[0029] When the device extracts stem cells, the extraction head 10 can be pulled out of the protective groove 11, and then the extraction tube 9 is pulled, which can drive the storage tank 3 to overcome the elastic force of the coil spring 2 and rotate so that the winding wheel 6 can unwind the extraction tube 9. After the extraction tube 9 is pulled to a specified length, the extraction head 10 can be inserted into the stem cell, and the pump body 4 is started to transport the stem cells through the diversion of the extraction tube 9 to the storage tank 3 for collection. After the stem cell extraction is completed, the storage tank 3 can be reset by the elastic force of the coil spring 2, so that the extraction tube 9 is rewound to the inner side of the winding wheel 6 again, and then the extraction head 10 is inserted into the protective groove 11 for protection to prevent the extraction head 10 from being contaminated. When the stem cells are taken out later, the sealing cover can be opened to discharge the collected stem cells through the discharge pipe.
