Description

Stepless adjustment infusion hanger

technical field

The invention relates to the field of medical aids, in particular to a stepless adjustment infusion hanger.

Background technique

The stepless telescopic infusion hanger is widely used in hospital infusion therapy because of its convenient installation and use, accurate positioning, space saving, and at the same time it can effectively reduce the labor workload of medical staff. It has become an indispensable auxiliary in major hospitals. medical tools.

Referring to FIG. 1, it is a schematic structural diagram of a stepless telescopic infusion hanger that is widely used at present, including a hook 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, inverted The telescopic part composed of the cone 107, the infusion hook 108 and other components, and the control part composed of the movable pull ring 109 and the fixed ring 110, wherein the bead pressing sleeve 104 of the telescopic part is slidably fitted in the lumen of the outer sleeve 102 to press The lower circumferential surface of the ball sleeve 104 is provided with a circular hole for installing the steel ball 106, the large diameter end of the inverted cone 107 is clearance fit in the ball pressing sleeve 104, and a compression spring is arranged between the shaft end face of the large diameter end and the ball pressing sleeve 111. The small diameter end of the inverted cone protrudes 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 opening of the outer sleeve 102, and is fixed with the hook base 101 and pressed. The upper end of the ball sleeve control screw 105 is fixedly connected with the ball sleeve 104, and the lower end passes through the lower end opening of the sliding telescopic tube 103, wherein the fixed ring 110 of the control part is fixed on the hook base 101, and the movable pull ring 109 and the ball sleeve control screw The lower end of 105 is fixed and located in the fixing ring 110 .

When the ball pressing sleeve is in the initial state, under the action of the compression spring, the inverted cone moves downward, the large diameter end is located at the steel ball, the steel ball is pressed against the inner wall of the outer casing, and the axial displacement of the inverted cone is limited at the same time, so that the The sliding telescopic tube is positioned to form a locked state; when the movable pull ring and the fixed ring are held in hand to move the movable pull ring toward the lower side of the fixed ring, the ball-pressing sleeve controls the screw to pull the ball-pressing sleeve to move downward relative to the inverted cone. The compression spring is compressed, the steel ball slides to the small diameter end of the inverted cone, so that the steel ball is not subject to the pressing force of the inverted cone, and the steel ball is in a non-contact state with the inner wall of the outer casing. The height can be adjusted steplessly.

Since the control part of this type of stepless telescopic infusion hanger is installed on the outside of the telescopic part hook base, the control part is exposed, and it is easy to apply downward force to the control part in the locked state accidentally, causing damage to the steel ball and the inner wall of the outer tube. Serious wear, loss of positioning effect, resulting in the scrapping of the infusion hanger; in order to facilitate the operation of nursing staff, the overall size of the control part is usually set to 10cm*12cm, which is large in size, inconvenient for storage, and also affects the appearance; the movable pull ring of the control part, The fixing ring is a scattered part independent of each other, and the independence of the control part is poor. Due to the different heights of the rooms in each hospital, the size of the telescopic part (outer casing, sliding telescopic pipe) often changes, which makes it more complicated to assemble the control part.

At present, the existing stepless telescopic adjustment infusion hanger displacement devices on the market all adopt the above-mentioned control method or a variant form of this method, but in essence they are all direct axial displacement methods, which have the disadvantages of fast wear, excessive volume and cumbersome assembly. Defects, and how to overcome these defects are technical problems to be solved urgently by those skilled in the art.
