Abstract

The utility model discloses a drainage device, including the multiunit drainage tube, at least a set of drainage tube is different with adjacent drainage tube length. The technical scheme of the utility model, through making adjacent drainage tube length different, the drainage tube when having reduced the body cavity and having washed, drained blocks up the probability, has improved the reliability of using.

Description

Drainage device

Technical Field

The utility model relates to a drainage device, which belongs to the field of medical appliances.

Background

In clinical surgery, it is necessary to prevent infection or to prevent wound healing from being affected by discharging pus, blood, fluid, and the like accumulated between human tissues or in body cavities to the outside of the body using a drainage device, such as drainage, catheterization, and the like, or the accumulation of blood, body fluid, and the like in various organs.

In the related art, the drainage device is composed of a plurality of equal-length drainage tubes arranged in parallel. The drainage device of this kind of structure discovers in the use, when the thick drainage thing of discharge, because the even outflow of drainage thing, in case the condition that the jam formed each drainage tube and all blockked up easily appears, leads to unable smooth drainage.

Disclosure of Invention

The utility model provides a drainage device, through constructing the drainage tube into at least local gradient distribution, effectively reduced the probability that the drainage tube blockked up simultaneously, improved drainage efficiency to prior art not enough.

In order to achieve the above purpose, the present application is realized by the following technical scheme:

a drainage device comprises a plurality of groups of drainage tubes, wherein at least one group of drainage tubes is different from the adjacent drainage tubes in length.

Through the improvement, when drainage matter which is easy to block is thickened in drainage and the like, the condition that the drainage matter simultaneously blocks is avoided at least between drainage tubes with different lengths, so that the drainage device at least has one drainage tube for smooth drainage, and the blockage probability of the drainage device is reduced.

In some embodiments of the present invention, each set of drainage tubes is different in length from the adjacent drainage tubes.

In some embodiments of the present invention, the length of each group of drainage tubes is distributed in a gradient manner, and each of the drainage tubes has a different length from the adjacent drainage tube.

By constructing gradient distribution, other drainage tubes are in a normal drainage state at the same time even if the drainage tube is blocked.

Wherein the so-called gradient profile may be a uniform gradient profile, e.g. the length difference between adjacent drains is the same; non-uniform gradient distribution is also possible, for example, the difference in length between adjacent groups of draft tubes is different from the rest.

In some embodiments of the present invention, the gradient distribution of the length of the drainage tubes may be such that one end of all the drainage tubes is aligned without forming a gradient; it is also possible that both ends of the drainage tube are not aligned.

In some embodiments of the present invention, multiple sets of drainage tubes are sleeved onto the same outer sleeve.

One end of the drainage sleeve is connected to the same outer sleeve together, so that pus, blood, liquid and the like accumulated in the fluid cavity can be quickly and intensively drained.

In some embodiments of the present invention, the outer tube to which the plurality of sets of drainage tubes are sleeved is circular in cross section perpendicular to the length direction of the drainage tube.

In some embodiments of the present invention, one end of each set of drainage tubes is located in the drainage sleeve; each group of drainage tubes positioned in the sleeve are groove-shaped, each group of drainage tubes is provided with a front end opening, and the front end opening is an inclined plane.

The outlet of the drainage tube is designed into the inclined plane, so that interference and intersection are reduced when thick drainage materials are drained between the adjacent drainage tubes, and the drainage efficiency is further improved.

In some embodiments of the present invention, the drainage sleeve is a drainage groove.

In some embodiments of the present invention, the length difference between each drainage tube and the adjacent drainage tube in the length direction of the drainage tube is 1-2mm, and the distance between each drainage tube and the adjacent drainage tube in the length direction perpendicular to the drainage tube is 1-2 mm.

Through a large number of clinical tests, the applicant comprehensively considers the conditions of various common drainage objects, and under the gradient distribution, the accumulation can be enabled to effectively flow and the drainage of an adjacent drainage tube is not influenced when local blockage occurs.

The technical proposal of the utility model effectively reduces the probability of blockage of the drainage tube on the premise of not changing the basic structure of the drainage device; and the operation habit does not need to be changed, the method has general practicability in clinic and is easy to popularize and manufacture.

Drawings

FIG. 1 is a structural implementation of the drainage device of the present application;

in the drawings, icons A, B, C, D represent a drainage tube, R represents an end of the drainage tube located outside the body cavity, and F represents an end of the drainage tube located inside the body cavity, respectively.

Detailed Description

The following describes a specific implementation of the technical solution of the present invention with reference to the accompanying drawings and specific embodiments. The following and the shown structures are only schematic, and the description of the size, the length, the distance, the proportion, etc. are only relative conceptual illustrations, and do not limit the technical scheme of the invention. The scope of the present application is intended to cover the appended claims and equivalents thereof.

Referring to fig. 1, in one embodiment of the present invention, a drainage device is provided comprising A, B, C, D four drainage tubes, wherein a first end F of each drainage tube is sleeved to a same outer sleeve, the outer sleeve being located within a body cavity; the second end R of each drainage tube is positioned in the drainage sleeve, the second end is provided with a front end opening, and the front end opening is in an inclined plane shape.

Optionally, the first ends of the four drainage tubes are aligned and sleeved to the same outer sleeve.

Alternatively, the draft tube is groove-shaped, for example, having an upwardly open shape such as a concave, semicircular, etc. cross-section perpendicular to the length direction of the draft tube.

Optionally, the second ends of the four drainage tubes form uniform gradient distribution in the length direction, the length difference between each drainage tube and the adjacent drainage tube in the length direction of the drainage tube is 1-2mm, and the distance between each drainage tube and the adjacent drainage tube in the direction perpendicular to the length direction of the drainage tube is 1-2 mm.

Optionally, the radial widths of the four draft tubes perpendicular to the length direction of the draft tubes are different from each other, for example, the difference between the radial widths of the adjacent draft tubes is 5-10%.

Through the structural design, when the drainage device is used for draining accumulated matters, even if the accumulated matters are blocked at any position, such as the accumulated matters stagnate at the outlet of the drainage tube A, the outlet of the B, C, D drainage tube keeps unobstructed, and the drainage matters can be continuously led out, so that the blocking probability of the whole drainage device is greatly reduced.
