Description

Technical Field

[0001] The present invention relates to the technical field of stem cell collection, and in particular to a stem cell collection device. Background Art

[0002] Stem cell transplantation for the treatment of many difficult diseases such as heart disease, nervous system diseases, blood diseases, etc. has become a hot topic in current stem cell research and application, and is also used as a method for clinical treatment of difficult diseases.

[0003] For example, a stem cell collection device with announcement number CN214612474U is provided with a sleeve, a rubber piston, a piston rod, a piston button and a round coil spring. When the piston button is pressed downward with a finger, the rubber piston will be pushed downward through the piston rod. Since the rubber piston has a good fit with the inner wall of the sleeve, the air in the sleeve can be squeezed into the cylinder. At the same time, the rubber piston will also squeeze the round coil spring. The squeezed round coil spring will generate corresponding elastic force. Under the action of the elastic force, when the piston button is released, the rubber piston can be slowly pushed upward to achieve automatic pulling. By providing a slide groove, a limit ring, an elastic curved rod, a protrusion, a locking base and a circular groove, when the elastic curved rod is pushed along the slide groove, the position of the limit ring can be adjusted, which can control the distance that the rubber piston moves upward, help control the blood volume of the collected umbilical cord blood, and prevent the collected amount from being greater than the required amount, thereby causing blood waste. The protrusion located on the inner wall of the elastic curved rod will slide along the locking base, and the protrusion will snap into the circular grooves at different positions on the locking base, thereby fixing the position of the limit ring, and preventing the limit ring from accidentally sliding, thereby causing inaccurate collection volume. However, in actual use, after the blood leaves the human body or the storage bag, since the blood contains certain coagulation substances, an anticoagulant needs to be added to the blood and stirred with the blood to avoid coagulation of the blood and affect the subsequent separation of stem cells. After the blood is drawn, the blood and the anticoagulant need to be stirred, which increases the working steps and reduces the extraction efficiency of stem cells. In addition, anticoagulation operation needs to be performed immediately after the blood is taken out to avoid local coagulation in the blood that cannot be immediately anticoagulated. There are certain usage defects.

[0004] Therefore, we propose a stem cell collection device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a stem cell collection device to solve the problem proposed in the above background technology that after the blood leaves the human body or the storage bag, due to the presence of certain coagulation substances in the blood, an anticoagulant needs to be added to the blood and stirred to avoid blood coagulation affecting the subsequent separation of stem cells. After the blood is drawn, the blood and the anticoagulant need to be stirred again, which increases the working steps and reduces the efficiency of stem cell extraction.

[0028] 1. Rotating components are arranged inside and outside the hollow rod. When collecting blood, a needle is inserted into a blood vessel or a blood storage bag, and the hollow rod is pulled to move by a pull block. The hollow rod drives the piston sleeve to move inside the cylinder, so that blood can be drawn into the cylinder. The hollow rod can drive the support frame to move during the movement. After the support frame moves, one end of the connecting rope is connected to the mounting plate, so that the winding piece can be unwound after the hollow rod moves, and then the winding piece can be rotated, so that the rotating rod rotates.

The connecting rope is not easy to be loosened under the action of the spring. After the rotating rod rotates, the meshing of the first bevel gear and the second bevel gear drives the rotating shaft to rotate. After the rotating shaft rotates, the stirring rod can be driven to rotate. After the stirring rod rotates, the blood can be stirred, so that the blood and the anticoagulant are mixed to avoid blood coagulation. The rotating assembly allows the blood and the anticoagulant to be stirred and mixed inside the cylinder when the blood is extracted to avoid blood coagulation and affect the subsequent extraction of stem cells, thereby improving the efficiency of stem cell extraction, and the blood and the anticoagulant can be mixed in time to avoid local coagulation, thereby improving practicality.

[0029] 2. Before drawing blood, the pressing block can be pinched at the same time, so that the two sliding rods can be driven to approach at the same time. After the sliding rod slides on the fixed frame, the column rod can be moved by the connecting frame. After the column rod moves, it can push the movable block to move up through the sliding connection with the inclined groove on the movable block, so that the movable rod moves up. After the movable rod moves up, the telescopic spring can be stretched, so that the positioning sleeve can enter the inside of the accommodating groove, and then the positioning ring can be moved to drive the positioning rod to slide in the sliding groove. After moving, the pressing block can be released, and the movable rod can be reset under the action of the telescopic spring. The positioning sleeve can fit tightly with the cylinder body, so that the positioning ring can be positioned to prevent the positioning ring from moving. During the blood drawing process, the cylinder body is made of transparent material. The piston sleeve moves while the blood is being drawn, and the positioning is performed by the movement of the positioning rod and the piston sleeve, so that the user can draw blood quantitatively and improve the convenience of operation.

[0030] 3. Before drawing blood, anticoagulant can be prepared according to the collected blood volume, and the anticoagulant can be drawn through a needle. After that, the needle can be inserted into the cylinder through the rubber stopper, so that the anticoagulant can enter the cylinder through the connecting tube. The rubber stopper is provided to facilitate the insertion of the needle, which will not affect the internal environment of the cylinder and improve the practicality.
