Description

Technical Field

[0001] The utility model relates to the technical field of infusion sets, in particular to an infusion set with adjustable length. Background Art

[0002] An infusion set is a common medical consumable. After sterilization treatment, a channel between the vein and the medicine is established for intravenous infusion. The length of existing infusion sets is fixed during production, which makes it difficult to adjust the length of the infusion hose on the infusion set. The infusion hose is hung vertically in the air during infusion and is easily caught by other objects, causing drag on the infusion hose on the infusion set, thereby posing a safety hazard to the infusion hose during use and reducing the safety of the infusion set.

[0003] Patent CN215653063U proposes an infusion set with adjustable length. After the fixing frame is pulled out to separate the limiting block inside the fixing groove on the mounting block, the left movable block and the right movable block hinged thereto can be unfolded to place the infusion tube on the arc groove inside the left movable block and the right movable block can be closed to fix the two mounting blocks by pressing the fixing frame. Then the infusion tube is wrapped around the groove of the left movable block, and after being wrapped around the outside of the left movable block and the right movable block to squeeze the fixed block, the fixed block is used to squeeze the connecting spring through the connecting rod and the connecting block, so that the elastic force generated by the connecting spring fixes the infusion tube in the limiting groove of the fixed block, so that medical staff can adjust the length of the infusion tube conveniently. When the infusion tube needs to be heated, the heating wire can also be started to heat the infusion tube located on the outside of the left movable block and the right movable block, so as to improve the safety of the infusion set during use and the comfort of the patient during infusion.

[0004] The above scheme mainly winds the excess length of the infusion tube on the track formed by the fixed block and the movable block, but this method requires manual bypassing of the track of the fixed block and the movable block and clamping the infusion tube inside. When taking out the length, the infusion tube also needs to be manually released. Therefore, there is inconvenience in use, and it is impossible to conveniently limit and release the excess length of the infusion tube. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an infusion pump with adjustable length to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. After the infusion tube passes through the wire harness frame, it is squeezed by the convex columns staggered on both sides to form an S-shaped bend, so that the excess length of the infusion tube is retained, and the reserved length of the infusion tube is adjusted by the adjustment component, which makes it convenient to tighten, fix and release the excess length of the infusion tube. It can be used multiple times and saves materials.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a length-adjustable infusion pump, including a wire bundle frame, the top and bottom of the wire bundle frame are hollow, and an infusion tube passes through the wire bundle frame from top to bottom, and brackets are slidably inserted on both sides of the wire bundle frame, and top columns are equidistantly installed on the surface of the brackets, the top columns of the brackets on both sides of the wire bundle frame are staggered up and down, and adjustment components for adjusting the length of the infusion tube are arranged on both sides of the periphery of the wire bundle frame, and the adjustment components include a mounting frame, the mounting frame is fixed on the outer surface of the wire bundle frame, and two winding rollers are symmetrically installed on the surface of the mounting frame, a pull rope is wound on the surface of the winding roller, and the other end of the pull rope is fixed to the bracket on the corresponding side.

[0007] Furthermore, the adjustment component also includes a knob, and the outer end of the mounting frame is rotatably mounted with a knob through a bearing seat, and both ends of the knob are fixed with driving bevel gears, and the winding shafts of the two winding rollers pass through the mounting frame and are fixed with driven bevel gears, and the driving bevel gear is meshed and connected with the driven bevel gear.

[0008] Furthermore, guide cylinders are fixed at positions of the two ends of the mounting frame corresponding to the pull rope, and the pull rope passes through the guide cylinders.

[0009] Furthermore, friction lines are arranged on the surface of the turning knob, and a spring clip is arranged on the surface of the mounting frame corresponding to the turning knob, and the turning knob is clamped inside the spring clip.

[0010] Furthermore, a spring is fixed on the surface of the inserting frame between the two top pillars, and the other end of the spring is fixed to the outer wall of the wire harness frame.

[0011] Furthermore, two adhesive frames are symmetrically provided at the top and bottom of the wire bundle frame, and the adhesive frames are adhered to the surface of the infusion tube by medical tape.

[0012] Furthermore, the inner walls of the top and bottom openings of the wire harness frame are provided with sliding grooves, and slide plates are slidably inserted in the sliding grooves, and the bottom of the adhesive frame is fixed to the slide plates.

[0014] The utility model wraps the upper adhesive frame on the surface of the infusion tube and then adheres it with tape, which makes it convenient to roll up and adjust the length of the infusion tube. After the length is determined, the adhesive frame at the lower end is adhered and wrapped to the bottom of the infusion tube to keep the entire wire bundle frame fixed on the infusion tube, which is convenient for disassembly and installation and can be recycled.

[0015] The insertion rack of the utility model moves horizontally by the elastic force of the spring, and the top columns on both sides move toward the inside of the wire harness frame, squeezing the infusion tube into an S-shaped curve, thereby limiting the length of the infusion tube. The position of the insertion rack can be adjusted by adjusting the component, and the squeezed length of the infusion tube can also be adjusted.

[0016] The utility model is buckled on the surface of the turning knob by means of a spring clip, thereby preventing the turning knob from continuing to rotate.

[0017] Compared with the prior art, the utility model forms an S-shaped bend after the infusion tube passes through the wire harness frame through the convex columns staggered on both sides, thereby retaining the excess length of the infusion tube and adjusting the reserved length of the infusion tube through the adjustment component, so that the excess length of the infusion tube can be tightened, fixed and released conveniently, and can be used multiple times, saving materials.
