Description

Technical Field

[0001] This utility model is an infusion set with a winding structure, belonging to the technical field of infusion set equipment. Background Technology

[0002] Intravenous infusion is the most widely used treatment method in clinical practice. It is a method of introducing large amounts of sterile fluids, electrolytes, and drugs into the body through a vein by utilizing atmospheric pressure and hydrostatic pressure. Depending on the injection site and the type of infusion, it can be divided into peripheral intravenous infusion, central intravenous infusion, hyperalimentation infusion, and blood transfusion.

[0003] Conventional infusion sets do not have a winding mechanism, making them difficult to rewind after use. This results in messy and space-consuming centralized processing. There is an urgent need for an infusion set with a winding mechanism to solve these problems. Utility Model Content

This utility model has a reasonable structure and good practicality. By utilizing the rotation effect of the bearing, it is easy to wind up the infusion set and easy to remove, which improves convenience, makes centralized processing more orderly, and saves space.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an infusion set with a winding structure, comprising a tube body and a winding mechanism, wherein a bottle stopper plug is sealed to the upper end of the tube body, and the winding mechanism comprises a round shaft, ball bearings, and a square plate. An elastic band is installed on the annular side of the round shaft, and two ball bearings are provided, with a ring fixedly sleeved on the outer ring of each of the two ball bearings. Knobs are installed at the left and right ends of the round shaft, and magnetic blocks are installed inside the left and right ends of the round shaft. Magnetic rings are installed inside the inner ring of the bearing. The two magnetic blocks have opposite magnetic properties to the two magnetic rings. The left and right ends of the circular shaft are magnetically attached to the inner rings of the two ball bearings. A lead screw is screwed to the middle of the rear side of the square plate. A square block is fixed to the front end of the lead screw. A roller bearing is embedded in the rear side of the square block. The front end of the lead screw is fixedly attached to the inner ring of the roller bearing. An arc-shaped fitting piece is installed on the front side of the square block. Square columns are installed on the left and right ends of the front side of the square plate. Arc-shaped magnetic plates are installed at the front ends of the two square columns.

[0006] Furthermore, the two rings are each made of magnets, and the magnetism of the two rings is opposite to that of the two arc-shaped magnetic plates.

[0007] Furthermore, the two arc-shaped magnetic plates are magnetically attracted to the annular sides of the two circular rings.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: an infusion set with a winding structure, including a tube body 2 and a winding mechanism 4. A bottle stopper plug 1 is sealed to the upper end of the tube body 2. The winding mechanism 4 includes a circular shaft 40, ball bearings 42, and a square plate 44. An elastic band 403 is installed on the annular side of the circular shaft 40. Two ball bearings 42 are provided, and circular rings 41 are fixedly sleeved on the outer rings of the two ball bearings 42 respectively. Knobs 46 are installed at the left and right ends of the circular shaft 40. Magnetic blocks are installed inside the left and right ends of the circular shaft 40 respectively. Magnetic rings are installed inside the inner rings of the two ball bearings 42 respectively. The magnetic properties of the two magnetic blocks and the two magnetic rings are opposite. Both ends are magnetically attached to the inner rings of two ball bearings 42. A lead screw 45 is screwed to the middle of the rear side of the square plate 44. A square block 47 is fixed to the front end of the lead screw 45. A roller bearing 402 is embedded in the rear side of the square block 47. The front end of the lead screw 45 is fixedly attached to the inner ring of the roller bearing 402. An arc-shaped fitting piece 48 is installed on the front side of the square block 47. Square columns 401 are installed on the left and right ends of the front side of the square plate 44. Arc-shaped magnetic plates 43 are installed on the front ends of the two square columns 401. This design solves the problem that the original device does not have a winding mechanism, which makes it difficult to wind up the infusion set after use, resulting in mess and large space occupation during centralized processing.

[0021] In the first embodiment of this utility model: two circular rings 41 are each made of magnets, and the magnetism of the two circular rings 41 is opposite to that of the two arc-shaped magnetic plates 43. This magnetic structure facilitates the attraction of the two arc-shaped magnetic plates 43 to the two circular rings 41. The two arc-shaped magnetic plates 43 are magnetically attracted to the annular sides of the two circular rings 41. An injection needle 6 is attached to the lower end of the tube body 2, facilitating intravenous infusion for the patient. A dropper 5 is integrally formed in the middle of the tube body 2, and a roller speed regulator 3 is attached to the middle of the tube body 2. A circular torsion ring 49 is fixed to the rear end of the lead screw 45. The roller speed regulator 3 facilitates the adjustment of the infusion rate. A precision filter screen is installed inside the tube body 2, facilitating the filtration of larger particles in the liquid medicine.

[0022] As a second embodiment of this utility model: In use, first lift the elastic band 403, then attach the side of the tube body 2 to the side of the round shaft 40, reset the elastic band 403, and initially clamp the tube body 2. Then rotate the screw 45, causing the screw 45 to move the arc-shaped fitting piece 48 forward. Under the action of the roller bearing 402, the arc-shaped fitting piece 48 will not rotate, further clamping the tube body 2. Then perform the infusion operation. When the infusion is finished and the tube body 2 needs to be rolled up, reset the arc-shaped fitting piece 48, then turn the knob 46 to rotate the round shaft 40. At this time, the inner rings of the two ball bearings 42 rotate. Under the clamping action of the elastic band 403, the round shaft 40 rotates to roll up the tube body 2. After the rolling is finished, forcefully separate the two arc-shaped magnetic plates 43 from the two rings 41, then pull any one of the ball bearings 42 to disengage it from the round shaft 40, and then remove the rolled-up tube body 2.
