specific Embodiment 2

[0018] Specific embodiment two, equal diameter drainage tube with three straight channels

[0019] See figure 2 , The invention relates to a three-channel straight drainage tube with equal diameter. The three-channel straight equal-diameter drainage tube is divided into three sections, which are respectively a straight channel groove section, a connecting section and a round pipe section. The connection method of the groove section, the connection section and the round pipe is the same as that in the first embodiment.

specific Embodiment 3

[0020] Specific embodiment three, equally divided three-channel helical equal-diameter drainage tube

[0021] See image 3 , The invention relates to a three-channel helical drainage tube of equal diameter. Divide the equally divided three-channel helical equal-diameter drainage tube into three sections, which are the grooved section of the spiral channel, the connecting section and the round pipe section. The connection method of the groove section, the connection section and the round pipe is the same as that in the first embodiment.

specific Embodiment 4

[0022] Specific embodiment four, equal diameter drainage tube with three straight channels with holes

[0023] See Figure 4 , The invention relates to a three-channel straight drainage tube with holes and equal diameters. The wall of the hole is a sealed hole, the opening of the hole is at the insertion end, and the hole ends at 100mm from the end of the round hole. The three-channel straight drainage tube with holes and equal diameters is divided into three sections, which are respectively a straight channel groove section, a connecting section and a round pipe section. The connection method of the groove section, the connection section and the round pipe is the same as that in the first embodiment.

Abstract

The invention relates to five shaped multichannel spiral or straight form pored equal-diameter drainage tubes. Each drainage tube is characterized in that a grooved section, a connection section and a circular tube section of the drainage tube are prepared by silica gel materials having the same diameter. Two cut planes meet in a line at parallel connection positions of the channel grooved section and the connection section. Semicircles are intersected at parallel connection positions of the channel grooved section and the connection section. Rectangles are intersected at parallel connection positions of the channel grooved section and the connection section. Crossed four-channel spiral, equant three-channel straight form and equant three-channel spiral equal-diameter drainage tubes are provided. The crossed four-channel spiral drainage tube comprises the crossed four-channel spiral grooved section, the connection section and the circular tube section. The equant three-channel straight form and spiral form pored equal-diameter drainage tubes are characterized in that a wall of a hole of the equant three-channel straight form pored equal-diameter drainage tube is a sealed hole, and an opening of the hole is positioned at an insertion end for inserting an indwelling needle from an outer end.

Description

technical field [0001] The invention relates to five kinds of special-shaped multi-channel spiral or straight drainage tubes with holes and equal diameters, belonging to the field of medical instruments. Background technique [0002] In the known cross four-channel spiral drainage tube, the junction of the cross four-channel spiral groove section and the circular pipe section is connected by an adhesive wrapping method, and the diameter increases at the glued outer wrap. The part with increased diameter is also inserted into the human body, so the insertion and removal of the junction of the cross four-channel spiral groove section and the circular pipe section will cause human tissue strain and pain. It is necessary to develop a drainage tube with a cross four-channel helix and equal diameter. The known drainage tube does not have a flushing hole, nor does it have three-channel straight and spiral drainage tubes. Contents of the invention [0003] The present invention ...
