Flow regulator IV infusion set with good venting function
The difference between flow regulator IV infusion set and ordinary infusion set is the different material and pore size of the infusion set filter membrane. In addition, the flow regulator IV infusion set adds a disc filter under the Mofetil drip tube, and the scalp needle connection is a spiral interface, which is more conducive to connecting the indwelling needle for needleless puncture. Compared with the two groups, the successful rate of venting in the flow regulator IV infusion set group was significantly higher than that in the general infuser group because the flow regulator IV infusion set had an automatic venting function without squeezing the Mofetil drip tube, which not only shortened the venting time but also improved the quality of infusion. According to the principle of physical free fall movement, the higher the height, the faster the speed, as the Mofetil drip tube of the common infusion set is higher than the separated precision filter of the flow regulator IV infusion set, the liquid falls faster when the flow rate reaches a certain value. When the flow rate reaches a certain value, it is easier to produce tiny bubbles in the infusion tube due to the physical air-absorption effect.
Flow regulator IV infusion set with less bleeding back
Due to the untimely inspection, it is easy to cause the phenomenon of bleeding back when the liquid drops empty. The bleeding back will bring panic to the patients and families, and the families and patients will not get good rest due to high tension, while the nurses need to increase the frequency of rounds, which increases the workload. When infusing again after blood return, further exhaust is needed, and sometimes the needle will be clogged. If the air is not exhausted properly when infusing again, air embolism will be formed, which may cause serious air embolism in the body, easily leading to medical disputes and dissatisfaction of patients and family members with nursing staff. The flow regulator infusion device is equipped with a stop-flow valve, in the process of clinical intravenous infusion, when the liquid is nearly finished dripping, the stop-flow valve will completely block the outlet, so that the infusion line between the lower outlet of the drip tube and the infusion needle is filled with liquid, which not only can prevent air from entering the vein, but also can effectively stop the blood in the blood vessels from refluxing and prevent the phenomenon of reflux, which not only ensures the safety of the whole process of patient infusion, but also reduces It not only ensures the safety of the whole process of patient infusion, but also reduces the mental pressure and work pressure of medical personnel.
Flow regulator IV infusion set with less skin reaction
In 1985, Falchuk et al. proposed through clinical verification that infusion phlebitis was related to particles in the drug solution; in 1977, Rusmin et al. studied the relationship between particle contamination in infusion solution and phlebitis and confirmed that the amount of particles was closely related to the occurrence of phlebitis. In 1977, when Rusmin et al. studied the relationship between particulate contamination in infusion solution and phlebitis, they confirmed that the amount of particulate was closely related to the occurrence of phlebitis. The 2000 edition of the Chinese Pharmacopoeia stipulates that the particulate inspection of injection solutions over 100 mL should not exceed 20 particles with a diameter greater than 10 μm in 1 mL, and not more than 2 particles with a diameter greater than 25 μm. Insoluble particles entering the human blood circulation may produce phlebitis, pulmonary edema, allergic reactions, local tissue embolism and necrosis, tumor formation and tumor-like reactions. As more and more attention has been paid to the reduction of particles in infusion, the flow regulator infusion device can effectively filter out insoluble particles in the drug solution compared with the current common infusion devices (filter media pore size 10μm to 12μm) because of its terminal filter with 3μm pore size, thus reducing the irritation of particles to blood vessels
