[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Please refer to Figures 1-4 The embodiment provides a technical solution:

[0027] A multi-angle elbow fixator comprises a moving mechanism 1, a rotating mechanism 2 rotatably installed on the upper side of the moving mechanism 1, and an elbow fixator 3 fixedly installed on the upper surface of the rotating mechanism 2. The moving mechanism 1 comprises a support platform 11, a connecting hole 13 formed in the middle position of the upper surface of the support platform 11, and a connecting sleeve 12 welded to the middle position of the upper surface of the support platform 11. A plurality of support columns 14 are welded to the lower surface of the support platform 11, and universal wheels 15 are fixedly installed on the lower ends of the support columns 14. Through the above-mentioned mechanism, the arm of the person being collected can be moved stably during the collection of hematopoietic stem cells, and the influence on the collection caused by the numbness of the arm of the person being collected can be prevented.

[0028] Further, the rotating mechanism 2 comprises a rotating platform 21 and a connecting column 24 welded to the lower surface of the rotating platform 21. A spring 23 is arranged on the outer side of the connecting column 24, and an auxiliary sheet 22 is welded to the top end of the spring 23. The auxiliary sheet 22 is tightly attached to the lower surface of the rotating platform 21.

[0029] Further, a handle 31 is fixedly installed on the upper end of the middle position of the surface of the elbow fixator 3 on the left and right sides. A sponge sleeve is wrapped around the outer surface of the handle 31 to increase the comfort of the user when gripping.

[0030] In the embodiment, there are four support columns 14, which are distributed at the four corners of a rhombus to better support.

[0031] In the embodiment, a rubber ring is arranged at the top end of the connecting sleeve 12. The diameter of the connecting sleeve 12 is greater than the diameter of the connecting hole 13. When the rubber ring contacts the lower surface of the rotating platform 21, the friction force prevents the rotating platform 21 from continuing to rotate.

[0032] In the embodiment, the connecting column 24 is arranged through the connecting hole 13, and the spring 23 is placed inside the connecting sleeve 12 and is limited.

[0033] In the embodiment, the upper surface of the auxiliary sheet 22 is smooth, the diameter of the auxiliary sheet 22 is equal to the inner diameter of the connecting sleeve 12, and the friction force generated by the contact between the auxiliary sheet 22 and the rotating platform 21 is reduced.

[0034] In the embodiment, when no external force is applied, there is a gap between the lower surface of the rotating platform 21 and the rubber ring at the top end of the connecting sleeve 12, and when the arm of the collected person is placed into the elbow fixer 3, the weight of the arm will press the rotating mechanism 2 downward to contact the rubber ring at the top end of the connecting sleeve 12.

[0035] It is worth mentioning that the structure and working principle of the universal wheel 15 involved in the embodiment are the same as those known by those skilled in the art, and will not be described here. The structure and working principle of the elbow fixer 3 involved in the embodiment are the same as those disclosed in the prior art, and will not be described here.

[0036] In the specific use process of the elbow multi-angle fixer, the device is first placed beside the sickbed, then the arm of the collected person is placed into the elbow fixer 3, and collection is performed. During the collection process, when the arm of the collected person is numb, the nursing staff can be signaled to adjust the angle. The nursing staff holds the handles 31 on both sides of the elbow fixer 3 with both hands, slowly lifts the elbow fixer 3 upward, until the lower surface of the rotating platform 21 can be separated from the upper surface of the connecting sleeve 12, and then the elbow fixer 3 can be slowly controlled to rotate to a certain extent based on the arm of the collected person. The moving mechanism 1 moves under the action of the universal wheel 15, and after moving, the elbow fixer 3 is slowly lowered until the rotating platform 21 contacts the connecting sleeve 12 again, the adjustment of the angle of the arm of the collected person is completed, and the degree of arm numbness is relieved.

[0037] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the utility model and are not intended to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
