が紹介されている。2. Description of the Related Art Conventionally, in operations such as thoracotomy and laparotomy, blood and exudate leaking from a wound or the like are separately supplied with a cleaning liquid supply catheter and a suction liquid suction catheter, respectively. The supply was repeated, the operation was complicated, and sometimes the operation was mistakenly reversed. Apart from performing suction and washing of body fluids such as blood and exudate using separate catheters, a device in which two catheters are assembled in one instrument is disclosed in Japanese Patent Application Laid-Open No. 57-177758.
Japanese Patent Application Laid-Open Publication No. H11-146131 discloses an example in which a harmful substance in the bladder is removed using a surgical suction device in which a syringe and a piston used in a syringe are improved. Japanese Patent Publication No. 4-9543 discloses an apparatus in which a cleaning liquid supply pipe and a suction pipe are integrated and a cleaning liquid supply operation and a suction operation are alternately performed from one outlet pipe.

ことである。However, the apparatus in which the cleaning liquid supply tube and the suction tube are assembled in one instrument is a single operation in which the cleaning liquid supply operation and the suction operation are alternately performed. During the cleaning liquid supply operation, pus generated from the wound and harmful substances in the body may diffuse and transfer to other places, and the substance sucked at the tip of the suction tube may block the tube and suck There was a danger that an unexpected situation would occur in which suction could not be performed when switching to the operation. An object of the present invention is to constantly aspirate blood or exudate leaking from a wound or the like and to supply a washing liquid as needed, thereby facilitating the aspiration operation by cleaning the wound and fluidizing the blood or exudate. It is to provide a cleaning suction catheter.

に示すように平板状のものが好ましい。As shown in FIGS. 3 to 5, the lumen opening / closing device 3 forms a tubular body 13 for accommodating a first tube 4 having a first lumen 1 in a cross-sectional direction, and a push button. Press plate
A spring 12 that urges a push plate 11 provided between the 11 and the upper outer wall of the tubular body 13 in a direction to push back, and penetrates through the thick wall of the tubular body 13 from around the spring 12 from the push plate 11. The support frame 14 is disposed on the lower outer wall of the tubular body 11 through the slit 15 formed as described above, and surrounds and accommodates the elastic tube 10 in the cross-sectional direction. In the drawings, the tubular body 13 is a cylindrical body, but may be a square tubular body. Examples of the material of the push plate 11 and the support frame 14 include a thermoplastic resin, a thermosetting resin, and a metal. The support frame 14 is made of metal, ceramic wire, or the like, or an elongated wire made of a thermosetting resin or a thermoplastic resin, and has a U-shape. Then, two places of the front end that open in the support frame 14 is encapsulated in two places inside the outer periphery of the push plate 11, slits 15 and 15 at two locations within the wall of the tubular body 13, were respectively through, support frame 14 and tubular body
The lower tube 13 surrounds and accommodates the elastic tube 10 in a sectional direction. The lower outer wall of the tubular body 13 may be arc-shaped, but in order to facilitate the flattening of the elastic tube 10, FIG.
