Description
Technical Field
The invention relates to the field of medical auxiliary instruments, in particular to a stepless adjusting infusion hanger.
Background
The stepless telescopic transfusion hanging bracket is convenient to install and use, accurate in positioning, space-saving, and capable of effectively reducing the labor workload of medical care personnel, so that the stepless telescopic transfusion hanging bracket is widely applied to transfusion treatment work in hospitals, and becomes an indispensable auxiliary medical tool for all hospitals.
Referring to fig. 1, which is a schematic structural view of a stepless telescopic transfusion hanger widely used at present, the hanger comprises a telescopic part consisting of a hanger base 101, an outer sleeve 102, a sliding telescopic tube 103, a ball pressing sleeve 104, a ball pressing sleeve control screw 105, steel balls 106, an inverted cone 107, a transfusion hanger 108 and other parts, and a control part consisting of a movable pull ring 109 and a fixed ring 110, wherein the ball pressing sleeve 104 of the telescopic part is in sliding fit in a tube cavity of the outer sleeve 102, a round hole for installing the steel balls 106 is arranged on the circumferential surface of the lower part of the ball pressing sleeve 104, the large-diameter end of the inverted cone 107 is in clearance fit in the ball pressing sleeve 104, a compression spring 111 is arranged between the shaft end surface of the large-diameter end and the ball pressing sleeve, the small-diameter end of the inverted cone extends out of the ball pressing sleeve 104 and is fixedly connected with the upper end of the sliding telescopic tube 103, the lower end of the sliding telescopic tube 103 extends out of the lower end of the outer sleeve 102 and is fixed with the hanger base 101, the upper end of the control screw 105 of the ball pressing sleeve is fixedly connected with the ball pressing sleeve 104, the lower end of the control screw penetrates through the lower end opening of the sliding telescopic pipe 103, the fixing ring 110 of the control part is fixed on the hook base 101, and the movable pull ring 109 is fixed with the lower end of the control screw 105 of the ball pressing sleeve and is positioned in the fixing ring 110.
When the ball pressing sleeve is in an initial state, the inverted cone moves downwards under the action of the compression spring, the large-diameter end is positioned at the steel ball, the steel ball is tightly pressed on the inner wall of the outer sleeve, and meanwhile, the axial displacement of the inverted cone is limited, so that the sliding telescopic pipe is positioned to form a locking state; when the movable pull ring and the fixed ring are held by a hand, the movable pull ring moves towards the lower edge of the fixed ring, the ball pressing sleeve controls the screw rod to pull the ball pressing sleeve to move downwards relative to the inverted cone, the compression spring is compressed, the steel ball slides to the small-diameter end of the inverted cone, the steel ball is free from the extrusion force of the inverted cone, the steel ball and the inner wall of the outer sleeve are in a non-contact state, at the moment, the sliding telescopic pipe can move up and down, and the height of the hook base is adjusted in a stepless mode.
Because the control part of the stepless telescopic transfusion hanging bracket is arranged outside the hook base of the telescopic part and is exposed outside, the control part is easy to apply a downward moving strong force to the control part when the control part is in a locking state by accident, the steel balls and the inner wall of the outer tube are seriously abraded, the positioning effect is lost, and the transfusion hanging bracket is scrapped; for the convenience of operation of nursing staff, the overall size of the control part is usually set to 10cm by 12cm, and the control part is large in size, inconvenient to store and influence the appearance; the movable pull ring and the fixed ring of the control part are mutually independent scattered parts, the control part is poor in independence, and due to different heights of rooms of hospitals, the sizes of the telescopic parts (the outer sleeve and the sliding telescopic pipe) are changed frequently, so that the control part is complex to assemble.
At present, the existing stepless telescopic regulation transfusion hanger displacement device on the market adopts the control mode or the variation mode of the mode, but is actually a direct axial displacement mode, has the defects of fast abrasion, overlarge volume and fussy assembly, and solves the technical problems to be solved urgently by technical personnel in the field.
