Description

Drainage tube with cross spiral structure

Technical field

This utility model relates to a kind of medical drainage device, relates in particular to a kind of drainage tube with cross spiral structure.

Background technology

Drainage tube, in the existing long-term clinical practice of surgical postoperative, has important effect for the drain of postoperative abdominal cavity liquid, gas and the judgement of peritoneal fluid character etc.The sixties in 20th century, Madding and Kennedy pointed out, surgical drainage can be saved patient's life, showed necessity and the importance of drain in surgery diagnosis of disease process.

Its purpose of surgical drainage mainly comprises drain and detection.Drain is mainly that drain gas, liquid (Digestive system, peritoneal fluid, pus, otch transudate) are to external, thereby reach pus or the slough of getting rid of abscess or other purulent lesions, preclude blood, transudate or Digestive system are accumulated in body cavity, prevent secondary infection, histologic lesion, reduce local pressure, reduce adhesion, impel the operating field dead space to dwindle or closed, and remove biliary tract, the gastral purpose such as symptom of blocking.

The drainage tube that existing surgery is used has a variety of, and at present, comparatively approval is that a kind of Drainage Section is difficult for being flattened by external force, and the drainage channel on the sidewall of Drainage Section is difficult for the drainage tube that is organized the sealings such as fragment, clot, blocks.The patent documentation that is 201978308U as publication number discloses a kind of resistance to compression, anti-blocking drainage tube, be provided with the drainage tube main body, the drainage tube main body comprises Drainage Section part and cylindrical tube part, Drainage Section part inner chamber is provided with the cross supporting rib stiffener, the cross supporting rib stiffener is separated into four drainage lumens by the cavity of Drainage Section part, and each drainage lumens wall has the drain notch.

The drainage speed of drainage tube is limited to the cross-sectional sizes of drainage trough, increases the drainage tube volume and can increase patient trauma and pain, extend patient's the convalescence after Miles operation, but reducing the drainage tube size can reduce drainage speed again, increases treatment time and expense.Therefore, in the situation that keep the drainage tube size constancy, increase the drainage speed of drainage tube, guarantee enough resistance to compression degree simultaneously, become the main direction of drainage tube research.

The utility model content

For accelerating drainage speed, promote the comprcssive strength of drainage tube, this utility model provides a kind of simple and practical, drainage tube with cross spiral structure that drainage effect is good.

A kind of drainage tube with cross spiral structure, comprise the Drainage Section, joining section and the hollow body section that are connected successively, described Drainage Section intracavity is provided with the cross reinforcement, described cross reinforcement is partitioned into four drainage channels by the cavity of Drainage Section, have the drain notch on tube wall corresponding to each drainage channel, and the distortion of whole Drainage Section in the shape of a spiral.

Drainage tube in the technical program is divided into Drainage Section, joining section and the hollow body section be connected successively, one-body molded by corresponding process equipment, has tensile strength preferably.When being used, Drainage Section inserts in patient body, be positioned at its inner cross reinforcement cavity is divided into to four drainage channels, each drainage channel extends along the body length direction in the shape of a spiral, according to the fluid motion rule, measure-alike drainage channel, the relatively linear drainage channel of spiral helicine drainage channel, have better drainage speed, promoted the drainage flow in the unit interval.

According to helical form drainage channel drainage speed characteristic faster, can suitably reduce the sectional dimension of existing drainage tube, can reach the drainage effect that is equal to existing drainage tube, can reduce patient's wound and pain, shorten patient's recovery time.

Simultaneously, drainage tube in this utility model can also prevent from organizing fragment, clot to enter in drainage channel, the corresponding drain notch of each drainage channel, the drain notch is opened on tube wall, its size is less than the Breadth Maximum of drainage channel, and the drain notch also in the shape of a spiral, organize fragment and blood clot to be difficult to enter in drainage channel, even some undersized fragment or blood clots organized enter in drainage channel through in the drain notch, also can in drainage channel, have free passage, and can not cause the obstruction of drainage channel.

As preferably, there are four independently flow-guiding channels in the body of described joining section, an end of each flow-guiding channel is communicated with a drainage channel, and the other end is communicated with described hollow body section.

Existing drainage tube only is divided into Drainage Section and hollow body section, between two sections bodys with the bonding or direct transition of one, if connect in bonding mode, there is the hidden danger of separating in drainage tube in the process of life-time service, if adopt the direct transition of one, the joining place of Drainage Section and hollow body section is generally in the skin wounds position, general vertical the hanging down of hollow body section of while, now, the degree of crook of joining place is larger, even likely flatten drainage tube, affect drainage speed.

In the technical program, set up a joining section between Drainage Section and hollow body section, the inside of joining section also is provided with the cross reinforcement, with the resistance to compression that improves this place, counter-bending ability, simultaneously, liquid in drainage channel enters in hollow body by corresponding flow-guiding channel, and does not affect whole drainage speed.

As preferably, on described Drainage Section, the length of each spiral is 3～6cm.

As preferably, the length of each spiral is 4.5cm.

The length of spiral to a certain extent, also affect drainage speed, also determine that hydrops sees through the complexity of drain notch simultaneously, by test repeatedly, when the length of each spiral is controlled between 3～6cm, there is drainage effect preferably, simultaneously, when the length of spiral is 4.5cm, the property indices of drainage tube is in the best.

As preferably, there are 5～8 spirals on whole Drainage Section.

The quantity of spiral determines the length of Drainage Section, simultaneously the length of Drainage Section also with insert body in position relevant, generally, there are 5～8 spirals on Drainage Section, or, according to concrete service condition, can carry out cutting to the quantity of spiral.

As preferably, described drainage tube is oblate pipe.

The shape of drainage tube is not limited to circle, can also be for oblate or oval, and in some specific occasion, oblate or oval-shaped drainage effect is better.

This utility model adopts the drainage channel design of spiral, has drainage speed faster, sets up a joining section simultaneously, strengthens resistance to compression and the flexural strength of drainage tube, simple in structure, practical.
