Description

Transfusion system

Technical Field

The utility model relates to the field of medical equipment, especially, relate to an infusion apparatus.

Background

When medical personnel hung water for patient, if once need hang many bottles of salt solution, hang up a bottle usually, insert the infusion bottle that waits to hang with bottle plug puncture ware again and continue to hang, this needs nurse to make a round trip many times, also has the way of increasing a section transfusion system connecting pipe now. When the infusion bottle hanging clamp is used, the connecting pipe is connected with an infusion bottle to be hung next, the connecting pipe is clamped by the water stop clamp, and the second bottle is hung by loosening the water stop clamp after the first bottle is hung. Because the plugging effect of the water stop clip cannot be guaranteed, the clip is loosened and leaks water, so that two bottles of saline water are mixed; the clamp is too tight, and the clamped infusion tube is difficult to restore to the original shape when the clamp is loosened, so that the infusion is not smooth.

Therefore, there is a need to provide a new infusion set to solve the above problems.

Detailed Description

As shown in fig. 1, an infusion set comprises a first connecting tube 1, a second connecting tube 2 and a lower tube 3, and is characterized in that: the first connecting pipe 1, the second connecting pipe 2 and the lower pipe 3 are connected through a three-way pipe 4, the second connecting pipe 2 is connected right above the lower pipe 3, and the number of the second connecting pipes 2 can be one or more; the first connecting pipe 1 is connected to the upper side of the lower pipe 3, the first connecting pipe 1 is provided with a bottle stopper puncture outfit 11, the second connecting pipe 2 is provided with a bottle stopper puncture outfit 11, a bottle opening fixer 12 and a cut-off device 5, and the outer part of the cut-off device 5 is provided with a housing 6. The lower tube 3 is provided with a Murphy's dropper 31, a flow rate regulator 32 and an infusion needle 33.

The bottle mouth fixer 12 is conical, and the bottle mouth fixer 12 can be made of elastic materials such as rubber; the bottom of the bottle mouth fixer 12 is clamped in an annular groove 21 on the surface of the second connecting pipe 2, the top of the bottle mouth fixer 12 is provided with an annular hoop 13, and the hoop 13 is used for hooping the infusion bottle mouth.

As shown in fig. 2, the cut-off device 5 includes an enlarged pipe 51 and a pipe plug 52, a circle of convex sealing ring 53 is arranged on the pipe plug 52, a concave sealing ring 54 is arranged above the cut-off device 5, the convex sealing ring 53 is matched with the concave sealing ring 54 in size and shape, the diameter of the pipe plug 52 is equal to the pipe diameter of the second connecting pipe 2, a plug seat 7 is arranged below the pipe plug 52, a circle of liquid passing holes 71 is arranged at the edge of the plug seat 7, the pipe plug 52 is pushed into the second connecting pipe 2 at the upper part, the convex sealing ring 53 enters the concave sealing ring 54, and the second connecting pipe 2 is plugged.
