When the infusion set is used, the bottle stopper puncture outfit on the existing infusion set is inserted into the rubber stopper 3, all the liquid medicine bottles needing to be injected are inserted into one liquid medicine needle assembly 1, the liquid medicine in the liquid medicine bottles can completely fill the liquid dropping pipe 13 at the moment, as the second through hole 20 is communicated with one first through hole 16 in the initial state, the liquid medicine enters the drip cup 2 at the moment and extrudes the soft part of the drip cup 2, the liquid medicine liquid level of the drip cup 2 is rapidly raised and overflows the hollow ring 23, the liquid medicine soaks the sanitary sponge 25 through the hole 24 on the hollow ring 23, the self weight of the sanitary sponge 25 is increased after absorbing partial liquid medicine, when the integral weight of the floating piece 7 and the weight control mechanism is greater than the magnetic force of the metal sheet 11 and the magnet sheet 12, the floating piece 7 and the weight control mechanism can be separated from the rotating piece 6 and fall on the liquid medicine liquid level, but the buoyancy of the liquid medicine to the floating piece 7 is always greater than the total weight of the floating piece 7 and the weight control mechanism, the floating piece 7 is ensured to always float on the liquid level, the liquid medicine in the drip cup 2 flows out through the infusion apparatus for intravenous injection, when the liquid medicine in the medicine bottle is dripped, the liquid level of the liquid medicine in the drip cup 2 begins to descend at the moment, the floating piece 7 also descends along with the liquid medicine level and drives the vertical rod 17 to descend together, when the vertical rod 17 is staggered with the step vertical wall of the annular notch 21 which is pressed against, the rotating piece 6 immediately and quickly rotates under the action of the torsion spring 10 at the moment until the vertical rod 17 is pressed against the next step vertical wall of the annular notch 21, the rotating piece 6 stops rotating at the moment, as the annular notch 21 is uniformly divided into a plurality of sections, the opening depth of each section is changed in a step-type equivalent manner, the step number of the annular notch 21 is consistent with the number of the first through holes 16, the design is to ensure that the included angle between every time of the rotating piece 6 and the two adjacent first through holes 16 is consistent when the rotating piece 6 rotates, therefore, the second through hole 20 on the rotating member 6 can be aligned with another first through hole 16 during each rotation, then liquid is dripped into the drip cup 2 through the liquid dripping tube 13 in another first through hole 16, in addition, the rotating member 6 is immediately and rapidly rotated under the action of the torsion spring 10, the process is extremely short in time consumption, the height of the liquid level of the liquid medicine in the drip cup 2 which continuously descends can be ignored, new liquid medicine is supplemented to ensure that the liquid medicine in the drip cup 2 stably does not move again, until the liquid medicine in the liquid medicine bottle is dripped again, the floating member 7 continuously falls and repeats the steps until all the liquid medicine in the medicine bottle is dripped, no new liquid medicine is supplemented in the drip cup 2 at the moment, the liquid level of the liquid medicine in the drip cup 2 gradually descends until the floating member 7 is attached to the second connecting member 8, the hollow circular ring 23 is inserted into the circular ring groove 26, the floating member 7 blocks the opening of the liquid conveying tube on the second connecting member 8, make the transfusion system have the automatic shutdown function, the length of drum 9 is greater than first connecting piece 5 in addition, rotating member 6, float 7, the distance sum of second connecting piece 8 and montant 17, can ensure that float 7 possesses sufficient walking space, whole infusion process no longer need artificially change the medicine bottle, the liquid medicine also can finish by injection, and even if it has a plurality of drip pipes 13 that do not connect the medicine bottle to press from both sides between two drip pipes 13 that are connected with the medicine bottle, whole injection process still can continue to go on.
Example 2
In example 1, the number of the dropping tubes 13 is several, if the liquid medicine needle assembly 1 on some dropping tubes 13 is not inserted with a medicine bottle, then the external air may enter into the infusion apparatus along the liquid medicine needle assembly 1 and the dropping tubes 13 to pollute the liquid medicine, and for this reason, referring to example 1, as another preferred embodiment of the present invention, referring to fig. 7, the difference from example 1 is that a flexible tube 14 is fixedly communicated with the dropping tube 13, a sealing cover 15 is fixedly connected with one end of the flexible tube 14 far away from the dropping tube 13, a flow stopping clip 18 is fittingly arranged on the outer walls of the dropping tube 13 and the flexible tube 14, the sealing cover 15 is a sealing cover used in the ordinary medical infusion apparatus, the flexible tube 14 is closer to the drip cup 2 than the flow stopping clip 18 on the dropping tube 13, when the liquid medicine needle assembly 1 on the dropping tube 13 is not inserted with a medicine bottle, then we use the flow stopping clip 18 to clip the dropping tube 13, so that the outside air can not enter the infusion apparatus through the liquid medicine needle assembly 1, but because the dropping liquid pipe 13 is clamped, no air pressure supplement exists in the infusion apparatus, and the liquid medicine in the infusion apparatus stops flowing, therefore, a hose 14 is fixedly communicated with the dropping liquid pipe 13, one end of the hose 14, which is far away from the dropping liquid pipe 13, is fixedly connected with a sealing cover 15, even if the dropping liquid pipe 13 is blocked, the air pressure supplement also exists in the infusion apparatus under the action of the hose 14 and the sealing cover 15, the sealing cover 15 can filter the air entering the infusion apparatus, and the dropping liquid pipe 13 connected with a medicine bottle uses a flow stopping clamp 18 to clamp the hose 14.
Example 3
In embodiment 1, if the order of infusing the medicine does not need to be noticed, the liquid medicine needle assembly 1 can be arbitrarily inserted into the medicine bottle, if the medicine needs to be filled according to the ordered sequence, the embodiment 1 needs to be further improved, referring to fig. 1-7, as another preferred embodiment of the present invention, the difference from embodiment 1 is that a number label is pasted on the outer wall of a plurality of liquid dropping pipes 13, the number size of the number label is increased in turn along the rotating direction of the rotating member 6, the liquid dropping pipe 13 marked with the smallest number label is selected to be communicated with the first bottle of the medicine liquid to be injected, and then the liquid dropping pipes 13 marked with the smallest number label are matched with the medicine liquid to be injected in turn according to the order of the number labels from small to large.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
