Description

The blind drainage tube of two-chamber list

This utility model belongs to medical science surgery assistive device field, the blind drainage tube of particularly a kind of two-chamber list.

Get stone, cut when detecting patient facing to cut in as renal pelvis excess of the kidney matter and bile duct procedure in studying medicine, to be difficult to determine whether postoperative can need injection, flushing, absorption specimen chemical examination treatment because of hemorrhage, infection, residual stones.If adopt single chamber drainage tube, run into above-mentioned situation and obviously be difficult to effectively handle.And general two-chamber T type pipe inner and outer pipes end all is open or the pipe end has lid (plug), perhaps T type pipe straight tube is angled with the interior pipe that passes the straight tube sidewall, big in tissue injury when each layer of stomach wall structure passes, and as need not carry out above-mentioned treatment the time, increased the chance of postoperative infection on the contrary.

The purpose of this utility model is to provide a kind of two-chamber list blind drainage tube, and tissue injury is little when utilizing it to undergo surgery, and easy infection not.

For reaching above-mentioned purpose, this utility model adopts following technical scheme: the blind drainage tube of two-chamber list, comprise the outer tube of head and end opening and the interior pipe that head and end passes the outer tube two ends, and leave the space between two pipes, interior pipe head end is open, endcapped.

Outer tube is T-shaped, and interior pipe head end is managed a side transverse tube from T shape and passed.

The outer tube head end is the mushroom head, and interior pipe head end therefrom passes.

Fig. 1 is this utility model structural representation;

Fig. 2 is the structural representation of embodiment 2:

Fig. 3 is the structural representation of embodiment 3.

The utility model can be made with silica gel, latex material, and appearance is single tube, (plug) not with cover, inner tube end Pass from the outer tube end port, tissue damage is little when using in the operation; In the time only need doing drainage, single blind pipe does not use, Its effect can reduce by drainage lumens and extraneous unnecessary passage just like single lumen catheter, reduces infection rate; Need Single blind pipe of can sterilizing when label taking basis, injection, flushing carries out in the puncture of cecum section, can cut when the needs enlargement discharge Fall cecum, make infection chance be down to minimum.
