Abstract

PROBLEM TO BE SOLVED: To provide an attraction drainage cord not leaving residue in a wound during removal, generating no clogging in the presence of organic residue or lumps and causing no pain to a patient during removal. SOLUTION: The attraction drainage cord (1) is formed by braiding a plurality of silk strands (2) of a type used in surgical suture and the central region thereof is loosely fitted into a tubular sheath (3). The sheath comprises a material, which is accelerated in the slide movement with respect to texture, increased in biocompatibility and can be coupled with a mechanical suction unit if necessary, for example, silicon.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravity drainage cord.

[0002]

2. Related Art When draining wounds, many modern drainage tubes require a low or high vacuum mechanical suction unit to remove blood clots and other organic matter. Lumps can easily cause clogging. Therefore, it is necessary to periodically use a device known as a tube squeezer, which causes discomfort and pain to the patient.

[0003] It is also known to drain a wound using a simple cotton gauze. Cotton gauze protrudes slightly out of the wound to carry out the liquid components and allows for rapid scar formation. This system is
It is derived from the method used since ancient Egypt.

[0004]

However, because the gauze tends to adhere to the wound wall, the use of a cord made of roll-up gauze can cause significant pain to the patient during removal from the wound. In addition, the material of the gauze is not very strong, especially during drainage removal, which often results in gauze particles being torn off and contaminating the wound.

[0005] The main object of the present invention is to overcome the disadvantages of the above-mentioned conventional devices, ie, they are completely free and do not adhere to the wall of the wound, so that they remain inside the wound even during removal. To create a gravity drainage code that does not leave residue, does not clog in the presence of organic residues or lumps, and does not harm the patient during removal .

[0006] Within the scope of the main objectives described above, the object of the present invention is simple and can be put into practical use relatively easily, it is safe to use and can be operated efficiently.
Another object is to provide a structure that is relatively inexpensive.

[0007]

SUMMARY OF THE INVENTION These and other objects are achieved by the attractive drainage cord of the present invention, which is formed by braiding a plurality of silk strands of the type used for surgical suturing. And a loose fit in the central region of the tubular sheath, which facilitates sliding against tissue to increase biocompatibility and can be coupled with a mechanical suction unit as needed It is characterized by being made of a suitable material, for example, silicon.

[0008] Further features and advantages will become more apparent from the following detailed description of the preferred and non-limiting embodiment of the gravitational drainage cord of the present invention, illustrated by way of non-limiting example in the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Shows generally the gravity drainage cord of the present invention. The cord 1 is formed by braiding a plurality of silk strands 2 of the type used for surgical suturing (a braid of the type used for forming shoelaces), preferably 8, 12, or 16 Code Strand 2
Is twisted around a central core wire 2a formed by twisting fibers, and wound around this.

In order to prevent the permeation of the organic liquid, the silk strand for suturing is treated with a waxy substance. It should be noted that, in the present invention, the silk strand is not treated, and the silk strand is not treated. It increases the drainage and removal effect of the organic liquid. In the central region, the cord 1 is loosely inserted into the tubular sheath 3. The sheath 3 is made of a material such as plastic, and particularly made of medical silicon which has been fully tested in the medical field.

The sheath 3 promotes sliding on the tissue during cord removal, increases biocompatibility, and can be coupled with a mechanical suction unit as required. The ends 4, 5 of the cord protrude from the sheath 3 to facilitate removal of fluid from the wound and to remove any obstructions or obstructions that impede proper flow of the fluid without causing pain to the patient. In contrast, the silk strand can be made smaller and can move.

[0012] Depending on the requirements, a radiopaque band for identification may be provided on the sheath. It should be pointed out that a plurality of (two, three or more) cords can be inserted into one sheath 3. In this case, the cord can be cut open and dispersed and spread within the wound to increase the drainage effect. The portion of the tubular sheath 3 provided for insertion into the cavity to be drained may be provided with a plurality of radial holes to facilitate drainage.

After a first period of several days, the silk cord is removed by sliding it outward. In this case, the opening of the tubular sheath can be closed by a removable cap. The present invention has been found to achieve the intended purpose. In particular, the present invention
It does not leave any residue in the wound during removal, does not clog in the presence of organic residues or clumps, does not harm the patient during removal, and is completely free. It was found that it was difficult to adhere to the tissue wall.

The present invention thus created can be variously modified within the scope of the inventive concept. Also, the details of the invention can be replaced with other technically equivalent elements. In practice, the materials used and the shapes and dimensions can be any according to requirements without departing from the protection scope according to the claims.

[0015]

The attraction drainage cord of the present invention is formed by braiding a plurality of silk strands of the type used for surgical suturing, and loosely fits in the central region of the tubular sheath. However, the drainage cord is completely free and adheres to the wound wall because it is made of a material, such as silicon, which facilitates sliding against tissue to increase biocompatibility and can be coupled to the mechanical suction unit as required Does not leave any residue in the wound during removal, does not clog in the presence of organic residues or lumps, and does not harm the patient during removal There is no.
