Abstract

The utility model discloses a drainage tube for drainage of haematocele in a wound after a major operation. The drainage tube comprises a drainage tube body, wherein the drainage tube body is of a double-cavity single tube structure. The drainage tube has the advantages that: the structure is simple, and the design is reasonable and novel; since the drainage tube adopts a double-cavity design, and the other cavity tube can be used for continuous suction after one cavity tube is blocked, the situation that the local hematoma or wound blood oozing and drainage tube failure are caused by the blocking of the drainage tube in the postoperative drainage process is avoided, and the risk of infection is reduced; and at the same time, drainage holes arranged at the front section of the drainage tube are designed to ensure the smooth drainage, and a nozzle is avoided being blocked, so that the drainage is carried out cleanly and thoroughly.

Description

The drainage tube that is used for hematocele drain in the wound after a kind of major operation

Technical field

This utility model relates to technical field of medical instruments, relates in particular to the drainage tube that is used for hematocele drain in the wound after the drainage tube major operation that is used for hematocele drain in the wound after a kind of major operation.

Background technology

After the major operation, the situation hemorrhage, that sepage is more can occur, like big joint replacement etc., the wound drain of bleeding adopts single lumen catheter as drainage tube; Generally needed drain 48 hours, and after drainage time reaches 12～24 hours,, can cause drainage tube to stop up because partial coagulation blood is piled up; Can't continue wound bled and carry out drain, the drainage tube that more renews difficulty is prone to pollute; Need take the wound wrapping again apart, the drainage tube that has stopped up is extracted, insert new drainage tube; Again wrap up, operation is scope very again, and the risk of infection is also arranged simultaneously.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art and the drainage tube that is used for hematocele drain in the wound after a kind of major operation is provided, and this drainage tube is owing to adopted two-chamber design, the drainage tube that need not more renew in the drain process after surgery.Particularly need drainage tube placed under the situation of long period, this utility model can form the drain of passing through preface, and is not limited by and drainage tube stops up.

The purpose of this utility model is achieved in that

Be used for the drainage tube of hematocele drain in the wound after a kind of major operation of this utility model, comprise the drainage tube body, said drainage tube body is a two-chamber single tube structure.

The drainage tube that is used for hematocele drain in the wound after the above-mentioned major operation, wherein, said drainage tube body is two round tubes that symmetric semicircle lumen tube is formed.

Be used for the drainage tube of hematocele drain in the wound after the above-mentioned major operation, wherein, be provided with several conduction holes equably on the outer wall of said drainage tube body leading portion.

Be used for the drainage tube of hematocele drain in the wound after the above-mentioned major operation, wherein, said drainage tube body also can be the two-tube structure side by side of two-chamber.

The advantage of this utility model: simple in structure, reasonable in design, novel, because drainage tube has adopted the two-chamber design, after a lumen stops up, can continue to attract through another lumen, avoided the replacing of drainage tube in the postoperative drainage process, eliminated the risk that infects; Simultaneously, the design of drainage tube leading portion conduction hole can guarantee that drain is unobstructed, avoids the mouth of pipe to stop up, and makes drain totally thorough.

The specific embodiment

To combine accompanying drawing that this utility model is described further below.See also Fig. 1 to Fig. 3; The drainage tube that is used for hematocele drain in the wound after this utility model major operation has been shown among the figure, has comprised drainage tube body 1, drainage tube body 1 is a two-chamber single tube structure; Drainage tube body 1 is two round tubes that symmetric

semicircle lumen tube

11,12 is formed; Be provided with several conduction holes 13 on the outer wall of drainage tube body 1 leading portion equably, in the present embodiment, left and right symmetrically respectively is provided with two row's conduction holes 13 on the outer wall of drainage tube body 1 leading portion.

Operation principle: see also Fig. 4, before the drain, this utility model drainage tube body 1.One is terminated at the outfan of vacuum motor 2; The other end (being provided with conduction hole 13 ends) inserts the wound that needs drain, and

lumen tube

11,12 can be opened simultaneously and bear suction respectively by two on-off control; Also can successively open and pass through the negative suction of preface, remove hydrops, hematocele in the body.The terminal junctions with vacuum motor 2 outfans of lumen tube 12 also can be provided with a three-way device, and this three-way device also links to each other with an airtight water pocket, in have the 5-7ml physiological saline solution.

When needs pass through the negative suction of preface, carry out the negative suction of postoperative 24h by lumen tube 11 earlier, from 24-48h; Because lumen tube 11 is stopped up by blood clot; Can open lumen tube 12, push the external airtight sacculus of lumen tube 12 in advance, wash away through the blood clot of physiological saline solution with lumen tube 12 drain oral areas; Connect the negative suction of B pipe again, can hematocele in the 24-48h or hydrops drain is complete.

The drainage tube body 1 of this utility model also can adopt the two-tube structure side by side of two-chamber.

For the needs wound drainage of longer time, also can adopt the design of three chambeies or four lumens.

Above embodiment only supplies to explain the usefulness of this utility model; But not to the restriction of this utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from this utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of this utility model, should be limited each claim.
