Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0028] like Figure 1 and Figure 2 As shown, a dual-tube infusion set includes: a support 20, a delivery chamber 21 fixedly installed on the wall of the support 20, the delivery chamber 21 being a rectangular hollow bag, the delivery chambers 21 being symmetrically installed on the wall of the support 20, a delivery tube 22 fixedly connected to the bottom of each delivery chamber 21, the delivery tube 22 being a hollow circular tube, a fusion chamber 23 fixedly connected to the bottom of all delivery tubes 22, the top of the fusion chamber 23 being able to connect to the symmetrical delivery tubes 22 simultaneously, a needle fixedly connected to the bottom of the fusion chamber 23, and a needle also being provided at the top of each delivery chamber 21. This is existing technology, so it will not be described in detail here.
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the wearing structure is set on the wall of the fusion chamber 23 to fix the fusion chamber 23 and the wrist. The wearing structure includes: an arc plate 30, a wristband 31, a side plate 33 and a through slot 34. The arc plate 30 is fixedly connected to the rear wall of the fusion chamber 23. The wristband 31 is fixedly connected to one side wall of the rear wall of the arc plate 30. The side plate 33 is fixedly connected to the side wall of the arc plate 30 opposite to the wristband 31. The through slot 34 is opened on the side wall of the side plate 33, and the wristband 31 can pass through the through slot 34.
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the through groove 34 can accommodate the sliding of the wristband 31. The arc plate 30 is an arc-shaped plate. The wristband 31 and the side plate 33 are symmetrical on both sides of the arc plate 30. The wristband 31 is rectangular. The wearing structure also includes: a groove 32, a pressure block 35, and a limiting tooth 36. The groove 32 is formed on the side wall of the wristband 31. The pressure block 35 is fixedly connected to the side wall of the side plate 33. The limiting tooth 36 is fixedly connected to the bottom of the pressure block 35. The groove 32 is a sawtooth-shaped groove, and the limiting tooth 36 is a sawtooth-shaped protrusion. The limiting tooth 36 is located on the wall of the pressure block 35 facing the through groove 34. 36 can engage with the wall of the wristband 31 in the groove 32. The pressure block 35 is an L-shaped block. The wearing structure also includes a frame 37, a frame 38, and a roller 39. The frame 37 is fixedly connected to the front wall of the fusion chamber 23. The frame 38 is fixedly connected to the front wall of the frame 37. The roller 39 is fixedly connected to the wall of the frame 38. The frame 38 is a rectangular frame. The frame 38 is connected to the fusion chamber 23 through the frame 37. The roller 39 is cylindrical. The roller 39 is located in the cavity of the frame 38. The internal size of the frame 38 can accommodate the passage of the wristband 31.
[0031] In practical use, first insert the needles at the top of all delivery chambers 21 into the required medicine bottle, then hang the bracket 20 at a high place, then insert the needle at the bottom of the fusion chamber 23 into the back of the patient's hand for infusion. After the needle on the wall of the fusion chamber 23 is inserted into the patient's hand, wrap the plastic wristband 31 around the patient's wrist, then pass the wristband 31 through the through groove 34 on the side plate 33 wall and make the limiting tooth 36 and the meshing groove 32 engage. Then, after the wristband 31 is fitted with the arc plate 30 to fit the patient's wrist, pass the excess wristband 31 through the through groove 34 along the cavity of the receiving frame 38 and wrap it around the wall of the receiving roller 39. At this point, the fixation is completed. When it is necessary to remove the needle, separate the excess wristband 31 from the wall of the receiving roller 39, then lift the pressure block 35 to make the limiting tooth 36 no longer engage with the meshing groove 32, and finally pull the wristband 31 completely out of the through groove 34 to complete the needle removal.
[0032] In summary, by setting up a wearing structure, the needle in the fusion chamber 23 can be prevented from rolling off during infusion. The wearing structure is tied to the patient's hand by the wristband 31, thereby effectively preventing the problem of the needle in the fusion chamber 23 rolling off during infusion.
[0033] like Figure 1 , Figure 2 and Figure 5As shown, the wall of the conveying pipe 22 is provided with an aggregate structure, which includes a block 40, a chute 41, a receiving groove 42, and a sub-block 43. The block 40 is slidably connected to the symmetrical wall of the conveying pipe 22. The chute 41 is opened on the wall of the block 40. The receiving groove 42 is symmetrically opened on the upper and lower walls of the block 40. The sub-block 43 is engaged in the receiving groove 42. The chute 41 is symmetrically opened on the wall of the block 40. The symmetrical conveying pipes 22 are respectively located in the symmetrical chute 41. The same sub-block 43 is provided in the receiving groove 42 on the wall of the block 40. The wall of each sub-block 43 is symmetrically opened with the same chute 41. The chute 41 can be adapted to the diameter of the conveying pipe 22.
[0034] In practical use, sliding the combined block 40 along the symmetrical conveying pipes 22 and moving the sub-block 43 out of the receiving groove 42 and along the symmetrical conveying pipes 22 can merge the symmetrical conveying pipes 22.
[0035] In summary, by setting up an aggregate structure, the symmetrical delivery tubes 22 can be kept together by adjusting the connecting block 40 or the sub-block 43, thereby preventing the symmetrical delivery tubes 22 from scattering and affecting patient movement.
[0036] Working principle: First, insert the needles at the top of all delivery chambers 21 into the required medicine bottles. Then, hang the bracket 20 at a high place. Next, insert the needle at the bottom of the fusion chamber 23 into the back of the patient's hand for infusion. After the needle on the wall of the fusion chamber 23 is inserted into the patient's hand, wrap the plastic wristband 31 around the patient's wrist. Then, pass the wristband 31 through the through groove 34 on the side plate 33 wall and make the limiting tooth 36 and the meshing groove 32 engage. Then, after the wristband 31 is fitted with the arc plate 30 to fit the patient's wrist, pass the excess wristband 31 through the through groove 34 along the cavity of the receiving frame 38 and wrap it around the wall of the receiving roller 39. The fixation is now complete. When it is necessary to remove the needle, separate the excess wristband 31 from the wall of the receiving roller 39. Then, hold the pressure block 35 to make the limiting tooth 36 no longer engage with the meshing groove 32. Finally, completely pull the wristband 31 out of the through groove 34 to complete the needle removal.
