Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for fixing a medical tube such as a drain tube used for an operation in the abdominal cavity, and more particularly to a method for easily dropping the tube into the abdominal cavity or out of the body. The present invention relates to a method for fixing a medical tube that can be prevented by the above method.

[0002]

2. Description of the Related Art For example, when a distal end portion of a drain tube is inserted into a body and placed there, as a method for preventing the tube from deeply entering the abdominal cavity and dropping out of the body, or coming out of the body, FIG. Drain tube 50 as shown
After installing at the optimal part in the body, open the slit 52 in the fixture 51 and set the drain tube 50,
After that, the fastener 51 is sewn to the skin 54 using the suture thread 53, the groove of the fastener 51 is tied with the tie 55, and the excess part of the tie 55 is cut to fix the drain tube 50, After placing the drain tube 66 at the optimal site in the abdominal cavity as shown in FIG. 8, the wound (drain tube insertion opening) 67 is sewn with a suture 68, and the drain tube 66 is further attached to the skin with another suture 69. After sewing and fixing directly to the skin, the drain tube 66 is pulled out little by little as the post-operative course progresses, and at this time, instead of using the suture thread 69 to sew the skin again, it is safe as shown in FIG. A fixing method for inserting the pin 70 into the drain tube 66 so as to prevent the pin 70 from falling into the abdominal cavity is known, and is useful as a simple method. In the case of intraperitoneal surgery, since the site where the exudate is likely to accumulate is empirically known depending on the operated site, the tip of the drain tube 66 is set to that position.

[0003]

By the way, although the fixing by the fixing tool 51 is surely fixed and is suitable for long-term indwelling, the work of fixing the fixing tool 51 itself to the skin is troublesome, and the patient's work is difficult. It is a burden. Further, there is a problem that the types of the fixing tools 51 need to be aligned according to the thickness of the drain tube 50 so as to be adapted thereto. Moreover, when pulling out the drain tube 50 little by little with the passage of time, the tie 55 cannot be loosened once it has been tightened, so the operator's experience is required to tighten the tie 55,
In addition, the drain tube 50 may be damaged during removal. In addition, a simple drop-out prevention method using sewing with a suture thread 69 or a safety pin 70 is a drain tube.
Injuries to the 66 lumens resulted in air leaks, which reduced drain efficiency and, to a lesser extent, leaked exudate from the puncture and soiled the surroundings. It can be prevented from falling into the inside, but can not be prevented from getting out of the body. In that case, leave it alone or if it should not come out, crush one lumen of the drain tube of 2 lumens or more and fix it Alternatively, the outer periphery of the double-structured drain tube is crushed, and the drain tube is sewn directly. Further, there has been an accident that the operator or the patient is injured by mistake when handling the safety pin 70.

Therefore, the present invention solves the above-mentioned conventional problems, and enables a medical tube to be simply fixed and a method for fixing the medical tube to be very easy when the tube is pulled out after the operation. The purpose is to provide.

Embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a medical tube (drain tube) 1 according to an embodiment. The tube 1 has a predetermined length of a tube body 2 made of a biocompatible material such as silicone rubber, vinyl chloride, urethane rubber, or the like.
It has. The tube body 2 has a perfect circular cross section, and a main lumen 3 is formed inside the tube body 2 in the longitudinal direction. Reference numeral 5 denotes a stainless steel clip for preventing the tube from falling off, and is attached to the outer peripheral wall of the tube body 2 so as to be sandwiched therebetween.

A method of using the tube 1 will be described. After the operation in the abdominal cavity is completed, the distal end of the tube main body 2 is inserted and installed in an optimal site in the abdominal cavity, the excess rear end is cut with scissors (not shown), and the newly appearing rear end is also suctioned (not shown). Connect to the container. After a while, wound (tube insertion opening)
6 are sewn together with a suture thread 7,
The other end of the thread 9 having one end connected thereto is sewn directly to the body surface so that the clip 5 moves only within the length of the thread 9, and then the clip 5 is connected to the tube. It is attached to the outer peripheral wall of the main body 2. As a result, the tube 1 does not fall into the abdominal cavity, and the clip 5 is connected to the thread 9 through the hole 8 and does not fall out of the body. The material of the thread 9 is not limited as long as it is suitable for medical use. Further, in the above description, the other end of the thread 9 is directly sewn to the body surface and fixed, but may be fixed to another medical tube fixing device instead.

After fixing the tube 1, the valve of the suction device is opened, and the exudate is discharged from the lumen 3 to the outside of the body. Thus, the tube 1 can be easily fixed by the clip 5. Clip 5 by the surgeon
Is very easy to remove, so that the burden on the patient is small even when the tube 1 is re-fixed when the tube 1 is pulled out over time.

FIG. 3 shows a modification of the tube. A part of the outer peripheral wall of a tube body 12 of the tube 11 is formed in a thick portion 13. The thick part 12 becomes a clip attachment part. With such a thick portion 13, even when the force of the spring of the clip 5 is strong, the lumen 14 is not crushed or damaged, and the drain effect can be maintained.

FIG. 4A shows a modification of the clip. The clip 15 differs from the clip 5 in that claws 16 are provided at both ends. When such a clip 15 is used, when the clip 15 is attached, the claw 16 bites into the outer peripheral wall of the tube body 2 as shown in FIG. 4 (B), and the attachment becomes reliable, so that the clip 15 can be prevented from falling off.

FIG. 5 shows another modification of the clip. As shown in FIG. 5 showing the state before mounting and FIG. 6 showing the state after mounting, the clip 17 is entirely made of a synthetic resin such as ABS resin, polypropylene, nylon, etc. Claws 19 are provided at both ends of the main body 18 which is urged open.
