Description
Technical Field
[0001] The utility model relates to the field of medicine delivery, in particular to a three-way connection component for medicine delivery. Background Art
[0002] Tee is also called pipe tee or tee pipe fitting, tee joint, etc. It is mainly used to change the direction of the fluid and is used at the branch pipe of the main pipeline. It can be classified according to the pipe diameter. It is generally made of carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon asphalt, PVC and other materials. In medical use, tee medication is to provide patients with additional nutrient solution under normal infusion conditions through a tee joint.
[0003] The three-way pipe fittings on the market today are all independent and there are no corresponding connecting pipe fittings. Before using the three-way pipe fittings to input the drug solution, it is necessary to bind and connect it with the infusion tube and the empty needle through items such as medical tape. However, the binding with tape is time-consuming, labor-intensive, and wastes materials. It is also not easy to disassemble it after use. In addition, since the infusion tube is soft and the gap of the empty needle is large, if the binding is not good, it is easy to leave a gap, causing liquid leakage. Therefore, a three-way drug administration connection component is proposed to solve the above problems. Utility Model Content

Before using the three-way pipe fitting to input the drug solution, it is necessary to bind and connect it with the infusion tube and the empty needle through items such as medical tape, but the binding with tape is time-consuming and labor-intensive, and wastes materials, and it is not easy to disassemble it after use. In addition, since the infusion tube is relatively soft and the gap of the empty needle is relatively large, if the binding is not good, it is easy to leave a gap, causing liquid leakage.

The utility model comprises a three-way pipe fitting body 1, two first infusion tubes 2 are fixedly connected inside the three-way pipe fitting body 1, a second infusion tube 3 is fixedly connected inside the three-way pipe fitting body 1, a connecting tube 4 is fixedly connected to the outside of the second infusion tube 3, a protective box 5 is movably connected to the outside of the connecting tube 4, two fixing devices 6 are fixedly connected inside the protective box 5 and are symmetrically distributed in the upper and lower parts, a needle tube 7 is clamped on the outside of a single first infusion tube 2, an annular plate 8 is fixedly connected to the outside of the first infusion tube 2, four arc plates 9 are symmetrically distributed in pairs in the upper and lower parts and in the left and right parts are slidably connected to the right side of the annular plate 8, and the outer sides of the four arc plates 9 are all threadedly connected to a rotating sleeve 10.
[0029] Among them, the two fixing devices 6 include threaded rods 61 that are connected to the internal threads of the protective box 5 and are symmetrically distributed up and down. The opposite sides of the two threaded rods 61 are fixedly connected with knobs 62 located on the outside of the protective box 5. The opposite sides of the two threaded rods 61 are rotatably connected with mounting plates 63 located inside the protective box 5. The opposite sides of the two mounting plates 63 are fixedly connected with friction pads 64.
[0030] By rotating the knob 62 , the two threaded rods will move relative to each other, and the mounting plate 63 will drive the friction pad 64 to press the infusion hose fixed outside the connecting tube 4 .
[0031] A flexible limiting ring 11 is fixedly connected to the interior of the protection box 5 , and the inner space of the flexible limiting ring 11 is smaller than the diameter of the connecting tube 4 .
[0032] When the protection box 5 is moved to the outside of the connecting tube 4 , the flexible limiting ring 11 will bend and flip and then recover, and under the restriction of the flexible limiting ring 11 , the protection box 5 will not actively separate from the outside of the connecting tube 4 .
