Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable blood transfusion stent. Background Art

[0002] Blood transfusion stents are a common equipment in hospitals, including side tubes and hook bases; blood transfusion stents are not only used in patient infusion rooms, but are also essential components of medical equipment such as hemodialysis machines and blood purification machines.

[0003] The prior art discloses a nursing infusion stand with application number: CN202021448072.X, which includes a movable base, a counterweight block is fixedly connected to the bottom of the movable base, a universal wheel body is fixedly connected to the bottom of the movable base, an infusion stand support rod is fixedly connected to the top of the movable base, an adjustment sleeve is fixedly connected to one end of the infusion stand support rod, and a limited elastic block is fixedly connected to the inner bottom wall of the adjustment sleeve. The nursing infusion stand can facilitate the medical staff of the nursing department to adjust the height of the infusion stand according to the use requirements when performing infusion for patients, and then adjust the height of the infusion bottle, thereby achieving the purpose of easy adjustment.

[0004] However, the prior art locks the adjusting sleeve in the support rod by threaded locking or by limiting holes and limiting pins. The operator needs to use both hands during the unlocking or locking process. The operation process is cumbersome and the unlocking or locking process takes a long time. If an infusion bottle needs to be added or replaced, the adjusting sleeve needs to be adjusted and the height of other infusion bottles needs to be adjusted at the same time. This is heavy, complicated to operate, and will affect the infusion of other patients. Utility Model Content

[0005] In view of the above problems, the utility model provides an adjustable blood transfusion stand, which can adjust the height of the hooks respectively, and then adjust the height of different blood bags, so that the height adjustment process of the blood transfusion stand is simpler and faster.

When in use, a blood bag is placed on one of the hooks, and the handle is turned to drive the gear one to rotate. The internal thread on the inner wall of the gear one cooperates with the thread of the threaded rod, so that the threaded rod moves up and down, and drives the hook to slide up and down on the column, so as to adjust the height of the blood bag. When the blood bag reaches a suitable height, the lock bolt is pushed to move toward the driving device by turning the handle to stop the driving device. The movements of each threaded rod do not interfere with each other. When it is necessary to hang and remove another blood bag, the above actions are repeated.

[0010] The utility model can adjust the heights of different blood bags by adjusting the heights of hooks at different positions, which is convenient and quick to adjust and will not affect blood transfusion of other patients.

[0011] In a further technical solution, the handle is horizontally inserted through the column and is rotatably connected to the column, and a second gear is provided at one end of the handle located inside the column, and the first gear meshes with the second gear. By rotating the handle, the second gear is driven to rotate, and the second gear meshes with the first gear, driving the first gear to rotate, thereby driving the first gear to rotate.

[0012] In a further technical solution, the gear one is placed at the bottom of the accommodating cavity, and cooperates with the meshing action of the gear two on the gear one to prevent the position of the gear one from moving.

[0013] In a further technical solution, a fixed block is provided in the column, and a through hole is provided on the fixed block for the turning handle rod to pass through, and a slideway is provided on the fixed block for the locking bolt to move up and down. By fixing the positions of the turning handle and the locking bolt by the fixed block, the turning handle and the locking bolt can remain relatively stable when they move.

[0014] In a further technical solution, the tumbler is rotatably connected to the column, one end of the tumbler located inside the column is gear-shaped, the lock bolt is "L"-shaped, a rack meshing with the end of the tumbler is longitudinally provided on the side of the lock bolt, the bottom of the lock bolt is arc-shaped, and a fixed gear meshing with the lock bolt is provided on the handle. By rotating the tumbler outside the column, the other end of the tumbler meshes with the side of the lock bolt longitudinally, thereby driving the lock bolt to move up and down, and the end of the lock bolt meshes with the tooth groove of the fixed gear to achieve the stopping of the driving device.

[0015] In a further technical solution, a rubber sleeve is provided on the other end of the handle, and the user can control the threaded rod to rise and fall through the handle, which is easy to operate.

[0016] In a further technical solution, a cap is detachably connected to the top of the column, and the cap is detachably arranged, so that each threaded rod can be installed and removed, and the installation and disassembly are simple and convenient.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model adjusts the height of different blood bags by adjusting the height of hooks at different positions, which is convenient and quick to adjust and will not affect blood transfusion of other patients;

[0019] 2. By turning the handle, the gear 2 is driven to rotate, and the gear 2 is meshed with the gear 1, driving the gear 1 to rotate. The internal thread on the inner wall of the gear 1 matches with the thread of the threaded rod, driving the threaded rod to move up and down along the column, thereby achieving the effect of easy adjustment;

[0020] 3. By turning the handle outside the column, the other end of the handle is longitudinally meshed with the side of the lock bolt, thereby driving the lock bolt to move up and down, and the end of the lock bolt is meshed with the tooth groove of the fixed gear to stop the driving device;

[0021] 4. The cap is detachable, and each threaded rod can be installed and disassembled, and the disassembly is easy. BRIEF DESCRIPTION OF THE DRAWINGS
