え、更には出血に至る点にあった。2. Description of the Related Art Drain tubes are widely used as surgical medical devices for discharging exudate, and have various inner and outer diameters.
Products having a cross-sectional structure or shape are commercially available. In a conventional drain tube, exudate flows into and out of the tube from the distal end of the tube when inserted into the exudate reservoir or from the distal end and side hole of the tube when the tube has side holes. The structure is The problem with the use of these tubes is that when the wound of the patient heals, the body tissue grows into the side hole of the tube and not only closes the side hole, but also removes the body when the tube is removed. This resulted in tissue tearing, causing significant pain to the patient and even leading to bleeding.

うことなく抜去することが出来る。[0003] As a countermeasure for this, there has been proposed a method in which a plurality of grooves are provided on the outside of the tube and the exudate is discharged by the grooves. It is a circular tube, and has a structure in which a groove is provided on the outer periphery of a part to be placed in the body. Therefore, since only the groove is provided on the outer surface in the longitudinal direction of the tube, it can be withdrawn without pain after healing the wound of the patient.

In order to improve this, a connection method in which all the grooves at the end are filled with an adhesive and bonded to the cover tube, and a side hole leading to the inner cavity is provided in the rib on the front side of the bonding portion, but all the grooves are considered. Needless to say, the side holes need to be provided in the spiral streak in order to secure the breaking strength, which is costly. In addition, in the outer groove, the exudate accumulates on the terminal side from the side hole and solidifies, which gradually grows into the side hole and becomes clogged, so that there is a case where discharge from the outer groove cannot be performed.

FIG. 1 is a side sectional view showing an embodiment of a drain tube according to the present invention, and FIG. 2 is a sectional view showing an adhesive portion between an outer groove tube and a cover tube of the drain tube according to the present invention. As shown in FIGS. 1 and 2, the drain tube of the present invention is obtained by covering an outer groove tube 1 with a cover tube 2. The outer groove tube 1 has a plurality of grooves 5 on the outer surface.
The adhesive 7 is applied to at least one end of the groove 5, and is adhesively fixed to the end of the cover tube 2.

ｍｍ以上の長めにすれば使用できる。It is desirable that the number and length of the grooves to which the adhesive 7 is applied be as small as possible and as short as possible in order to secure a higher flow rate. However, from the viewpoint of the joint strength between the two tubes, 5 to 50% of the total number of grooves is required. An adhesive is preferably applied to the number of grooves of 10 to 40%, more preferably 20 to 30%.
A coating length of 15 mm is desirable. When the number of grooves for applying the adhesive 7 is 5% or less of the whole, the application length is set to 15
If it is longer than mm, it can be used.

る。Immediately before the application portion of the adhesive 7, a slit 8 having an area equal to or larger than the cross-sectional area of the groove 5 is provided in the rib 6 on either side or one side thereof. It is desirable that the rear ends of the slits 8 coincide with each other so that the discharged liquid does not stay in the groove 5. The cover tube 2 is a straight round tube, and its inner diameter is desirably as small as possible so that the rib 6 of the outer groove tube 1 is not crushed so as not to be bent up. Therefore, the inner and outer diameters are determined by the hardness of the outer groove tube 1 and the cover tube 2.

It is not particularly limited as long as it is for medical use. The cross-sectional shape of the tube may be elliptical or elliptical in addition to circular. Further, a contrast line made of an X-ray opaque material may be provided in the outer groove tube 1 or the cover tube 2 depending on the purpose of use, and when both are provided, there is an advantage that the tip position of the cover tube 2 can be easily recognized. However, if the length of the uncovered portion of the cover tube 2 is grasped in advance, it is only necessary to provide the outer groove tube 1. Further, a connector for connecting to a continuous suction device or the like may be provided, or a sharp needle for puncturing the body may be detachably provided.
