A kind of floating ball multifunctional nursing infusion set

Abstract

The invention discloses a floating ball type multi-functional infusion apparatus for nursing, and belongs to the field of medical apparatus and instruments. Based on a common infusion apparatus structure, a floating ball device is arranged in a drip cup, the floating ball device comprises a screw rod, a floating ball, a funnel and an intubation tube; the upper end of the screw rod is fixedly connected to the inner wall of the drip cup through at least two connection rods, the screw rod is sleeved with the floating ball, the funnel is arranged at the outer side of the lower end of the screw rod, and a through hole is formed in the lower portion of the funnel; in an initial state, the floating ball is closely attached to the upper end of the funnel, and attachment positions are connected through threads; the upper end of the intubation tube is located in the funnel, the upper end of the intubation tube is higher than the through hole, the lower end of the intubation tube penetrates through the bottoms of the funnel and the drip cup in sequence and is located in an infusion hose. Through the floating ball type multi-functional infusion apparatus for nursing, the function of timely automatic stagnation can be ensured, the medicine liquid buoyancy force is made full use of, and when the automatic stagnation is achieved, the function of highly isolating the air is achieved; the infusion apparatus further can prevent a medicine liquid leakage situation, and be convenient to treat urgently.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a floating ball multifunctional nursing infusion set. Background technique [0002] The infusion set is a very common medical consumable, which establishes a channel between the vein and the liquid medicine for intravenous infusion. Generally, it is composed of intravenous needles, injection needles or infusion needles, needle caps, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, cork puncturers, air filters, etc. Some infusion sets also have injection pieces, dosing port, etc. During the infusion process of the infusion set, wait for the liquid level in the drip pot to be stable before infusion. At this time, the difference between the liquid column pressure and the blood pressure in the vein is constant (atmospheric pressure is mutually balanced, and the liquid column pressure is greater than the venous blood pressure), so that The liquid medicine is i...

AI Technical Summary

Problems solved by technology

However, once there are impurities or position deviation between the floating ball and the fitting parts, it will lead to loose fitting, greatly weakening or even losing the function of automatic liquid stop

That is, the tightness and stability of the connection between the floating ball and the fitting part need to be improved, and a device for isolating the air must be installed

In addition, most of the existing float stop devices are located at the bottom of the drip pot. If there is a problem with the tight fixation between the joint at the bottom of the drip pot and the float stop device, the liquid medicine will leak out, causing the liquid medicine to leak. waste, and it is more troublesome to clean up the liquid where the liquid drops
