The utility model belongs to the field of
medical instruments, and particularly relates to an improved gold substituting type tube oral automatic feeding device. The improved gold substituting type automatic tube
oral feeding device comprises a needle cylinder, a push rod, a
piston block and the like, the push rod is connected into the needle cylinder in a sliding mode and is composed of a cross plate and a circular block, the cross plate is located inside the needle cylinder, the circular block is located outside the needle cylinder, the
piston block is fixedly connected to the
tail end of the push rod, and the side edge of the
piston block is tightly attached to the inner wall of the needle cylinder. The piston block is in
sliding contact with the needle cylinder, and the bottom end of the piston block is in contact with the inner bottom end of the needle cylinder. Through the design of the infusion tube of a single-hole structure, fluid food can enter the
pharynx in a more concentrated mode, the
swallowing efficiency is remarkably improved, meanwhile, by means of
cooperative work of the rotating plate, the clamping block, the connecting plate and the inclined plane column, the infusion tube can be firmly clamped, displacement or falling off in the injection process is prevented, and even under the large
injection pressure, the infusion tube can not fall off. The infusion tube can be kept stable, and safety and smoothness in the feeding process are guaranteed.
