DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a liquid stopper dripper comprises a liquid inlet hopper 1, a drip hopper 2 is arranged on the bottom surface of the liquid inlet hopper 1, a fixing hole 6 is opened on the top surface of the liquid inlet hopper 1, a fixing ring 3 is fixedly installed on the bottom surface of the drip hopper 2, a liquid outlet pipe 19 is fixedly sleeved on the inner circular wall surface of the fixing ring 3, a supporting ring 20 is fixedly sleeved on the outer circular wall surface of the liquid outlet pipe 19, a liquid stop mechanism 10 for stopping liquid is arranged on the inner circular wall surface of the drip hopper 2, and a puncture mechanism 7 for puncturing an infusion bag is installed on the inner circular wall surface of the fixing hole 6;

[0023] The liquid stopping mechanism 10 comprises a bracket 11, the bracket 11 is fixedly sleeved on the inner circumferential wall surface of the drip bucket 2, a liquid stopping membrane 18 is fixedly sleeved inside the bracket 11, a placement hole 17 is provided on the inner bottom surface of the bracket 11, the outer circumferential wall surface of the liquid stopping membrane 18 is fixedly sleeved on the inner circumferential wall surface of the placement hole 17, a mounting plate 26 is fixedly sleeved on the inner circumferential wall surface of the drip bucket 2, a fine filter screen 13 is installed on the mounting plate 26, the fine filter screen 13 is wavy and is used to increase the contact area between the fine filter screen 13 and the liquid medicine, a support hole 12 is provided on the top surface of the mounting plate 26, the fine filter screen 13 is fixedly sleeved on the support hole 12, a mounting ring 15 is provided on the top surface of the mounting plate 26, two connecting columns 14 are fixedly installed on the top surface of the mounting plate 26, the top surface of the connecting column 14 is fixedly connected to the bottom surface of the mounting ring 15, and the inner circumferential wall surface of the mounting ring 15 is fixedly sleeved on the coarse filter screen 16;

[0024] Through the provided liquid inlet hopper 1 and the drip hopper 2, microplastics and drug crystals may enter the drug solution when the patient is infused with the liquid inlet hopper 1 and the drip hopper 2. The drug solution passes through the coarse filter 16 inside the mounting ring 15. The coarse filter 16 can preliminarily filter the microplastics and drug crystals in the drug solution. The drug solution contacts the fine filter 13 on the mounting plate 26 through the coarse filter 16. The fine filter 13 is wavy in shape, which can increase the contact area between the fine filter 13 and the drug solution, thereby further filtering the microplastics and drug crystals in the drug solution and preventing the drug from entering the drug solution. The microplastics and drug crystals in the medicine are blocked to prevent them from entering the patient's body. As the medicine continues to enter the patient's vein, the infusion liquid level in the drip bucket 2 continues to drop. When the infusion liquid level drops to the liquid-stopping membrane 18 in the bracket 11, the infusion stops automatically, thereby preventing air from entering the vein. Not only are the microplastics and drug crystals in the medicine filtered, but the infusion can also be automatically stopped, thereby improving the safety of infusion, reducing the workload of medical staff, achieving the effect of stopping the flow of medicine, and facilitating the staff to infuse the patient.

[0025] Example 2: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , the stopper dripper is different from the embodiment 1 in that the puncture mechanism 7 includes a puncture device 33, the puncture device 33 is fixedly sleeved on the inner wall of the fixing hole 6, the bottom surface of the puncture device 33 is provided with a liquid inlet hole 25, the outer wall of the puncture device 33 is movably sleeved with a protective cover 8, and the protective cover 8 can protect the puncture device 33. Through the set puncture device 33, the staff pierces the puncture device 33 into the infusion bag, so that the liquid in the infusion bag enters the inside of the liquid inlet funnel 1 and the drip funnel 2 through the liquid inlet hole 25 on the puncture device 33, so as to achieve the puncture effect on the bottle stopper;

[0026] The puncture mechanism 7 also includes an air inlet seat 29, which is installed on the outer circular wall of the puncture device 33. The outer circular wall of the puncture device 33 is provided with a connecting hole 28, and the connecting hole 28 is connected to the liquid inlet hole 25. The outer circular wall of the air inlet seat 29 is fixedly sleeved with the inner circular wall of the connecting hole 28, and the inner circular wall of the air inlet seat 29 is fixedly sleeved with a diaphragm 30. A plastic belt 31 is fixedly installed on the outer circular wall of the air inlet seat 29, and a plug 32 is fixedly installed on one side of the plastic belt 31. The plug 32 is movably sleeved with the inner circular wall of the air inlet seat 29. Through the set plastic belt 31, the staff inserts the plastic belt 31 into the air inlet seat 29, thereby blocking the air inlet seat 29. Through the set air inlet seat 29, the external air passes through the diaphragm 30 and enters the interior of the puncture device 33, and the liquid medicine from the infusion bag will also be blocked by the diaphragm 30, so as to balance the internal and external air pressures of the infusion bag during the infusion process, thereby helping the patient complete the infusion process.

[0027] The outer circumferential wall surface of the liquid inlet hopper 1 and the outer circumferential wall surface of the drip hopper 2 are fixedly connected with a connecting ring 27, and the outer circumferential wall surfaces of the two connecting rings 27 are fixedly connected with a fixing ring 9. By setting the fixing ring 9, the fixing ring 9 can fix the two connecting rings 27, thereby connecting and sealing the liquid inlet hopper 1 and the drip hopper 2.

[0028] The outer circumferential wall surface of the drip bucket 2 is fixedly sleeved with a support ring 5, and the outer circumferential wall surface of the support ring 5 is fixedly installed with two support boxes 21. A support rod 23 is fixedly installed inside the support box 21. The outer circumferential wall surface of the support rod 23 is elastically connected with a clamping plate 22, and the clamping plate 22 is movably sleeved with the support box 21. A circular through hole is opened on one side of the clamping plate 22, and the inner circumferential wall surface of the circular through hole is movably sleeved with the outer circumferential wall surface of the support rod 23. A spring 24 is movably sleeved on the outer circumferential wall surface of the support rod 23, and one end of the spring 24 is fixedly connected to the inner circumferential wall surface of the support box 21, and one end of the spring 24 is fixedly connected to the inner circumferential wall surface of the clamping plate 22.
