Description

  The present invention relates to an extracorporeal circuit system for processing blood by extracorporeal circulation used in cardiac surgery and the like, and an extracorporeal circuit system package for transporting the extracorporeal circuit system.

  In cardiac surgery, it is common to perform treatment while the heart is temporarily stopped and the blood flow is blocked. In that case, an extracorporeal circuit system that circulates blood outside the body is used. Yes.

  A conventional extracorporeal circuit system of this type has a device including an artificial lung that serves to remove carbon dioxide in blood and supply oxygen to blood, and a plurality of tubes connected to the device. The device and the plurality of tubes are each packed in a packing case and transported to a medical site. Then, before performing cardiac surgery, the device and the tube are taken out from the packing case, one end of each of the plurality of tubes is connected to a predetermined portion of the device, and the other end of the plurality of tubes is circulated through the blood. In addition, by connecting to a blood passage on the vein side (blood removal circuit), a blood passage on the artery side (blood feeding circuit), and the like, blood is extracorporeally circulated.

  However, since the connection work of the plurality of tubes is complicated, time-consuming, and there is a problem in workability, and there is a possibility of erroneous connection. They are stored together in one packing case and transported to the medical site.

  Connecting the tube to the apparatus in advance as described above is called “pre-connect”. As such a pre-connected system, Patent Document 1 below discloses a venous reservoir, an artificial lung, an arterial filter, and the like. A plurality of tubes, and a plurality of tubes are pre-connected to each member of the device, and a device having a plurality of tubes pre-connected is housed in a lower portion of the packaging case. A package of an extracorporeal circuit system in which a plurality of tubes wound thereon is placed is disclosed.

Further, in Patent Document 2 below, a blood processing apparatus having a blood reservoir and a blood oxygenator (corresponding to an oxygenator), a carrier provided on the back of the blood processing apparatus, and a box shape with a predetermined depth are provided. None, and an extracorporeal circuit configured to have a tray attached to a side of the blood processing apparatus, and a plurality of tubes connected to the blood processing apparatus are appropriately wound and accommodated in the tray A pack assembly for a circuit system is disclosed.
Japanese Patent No. 3738211 Special Table 2002-536131 Publication

  When the system in which a plurality of tubes are pre-connected to the apparatus is accommodated in the packaging case as in Patent Document 1, the tube is wound into a compact winding shape to the extent that it can be accommodated in the packaging case. There is a need. However, when the tube has a compact winding shape, the tube may be bent and kinked, or the tubes may be intertwined. If the tube is kinked, there is a possibility that the blood flowing inside the tube may be clogged or the flow rate may be reduced, so that it may not be used during surgery. In addition, if the tube is entangled, it is necessary to correct the entanglement, so the connection workability to the blood removal circuit, blood supply circuit, etc. is reduced, and if the tube is intricately entangled, After removing the tube once and correcting the entanglement, it may be connected to the main body again, resulting in a significant decrease in connection workability.

  For this reason, the plurality of tubes have a relatively large winding shape, and the extracorporeal circuit system is often packed in a corresponding large packing case. However, in that case, a large space is required for storing the system, and the number of systems that can be transported is reduced, so that the transportation efficiency is lowered. Further, unnecessary waste after the system is taken out from the packing case is increased. Problems arise.

  Further, in the packaging body of the cited document 1, a plurality of tubes are accommodated in the packaging case in a state of being placed above the device. However, when the winding shape of the tube is large, the tube is supported above the device. As a result, a part of the tube sometimes protrudes. When transported to a medical site in this state, the tube may drop downward and become kinked due to impact or vibration during transport and long-term storage.

  By the way, when a plurality of tubes extending in a predetermined length are collected in a predetermined winding shape, it has a relatively large weight. In the pack assembly of the system of the above cited reference 2, the wound tube is accommodated in the tray attached to the side of the blood processing apparatus so that the weight of the tube is supported by the bottom surface of the tray. It has become. For this reason, when the pack assembly of the system is housed in a packing case, the weight of the wound tube acts strongly on the bottom surface of the tray due to impact and vibration during transportation and long-term storage. The tube could be damaged.

  Therefore, the object of the present invention is to prevent kinking and entanglement of the circuit tube pre-connected to the apparatus main body, and to prevent damage to the apparatus main body and circuit tube due to impact and vibration during transportation and long-term storage. Another object is to provide an extracorporeal circuit system and an extracorporeal circuit system package.

  In order to achieve the above object, an extracorporeal circuit system of the present invention is an extracorporeal circuit system in which an apparatus main body including at least an artificial lung and a circuit tube connected to the apparatus main body are preconnected. A frame-like shape having a main body contact surface that is in contact with the main body, a side wall that rises from both sides of the main body contact surface, and a support surface that is supported at a predetermined interval with respect to the main body contact surface through the side wall. A holder is provided, and the main body contact surface of the holder is detachably fixed to a side surface of the apparatus main body, and the circuit tube is wound on the support surface of the holder while being detachable. It is characterized by being fixed to.

  According to the said invention, the circuit tube previously connected to the apparatus main body can be made into a compact winding shape, and can be attached to an apparatus main body, and the packing and taking-out operation | work of an extracorporeal circuit system can be made easy. In addition, since the circuit tube can be supported on the support surface of the holder having a relatively large area, it is possible to prevent kinking due to bending of the circuit tube, entanglement between the tubes, and the like. Furthermore, by placing the circuit tube on the support surface of the holder, the weight of the circuit tube is softly received against impacts, vibrations during transportation, and long-term storage due to the cushioning properties of the frame-shaped holder. It is possible to prevent damage to the device body and circuit tube. Furthermore, when removing the extracorporeal circuit system from the package, it can be easily removed by lifting the holder with one hand. Furthermore, setting can be performed smoothly and in a short time, and the holder can be removed after setting.

  In the extracorporeal circuit system according to the present invention, it is preferable that a tray is attached to the support surface of the holder, and at least a part of the circuit tube is accommodated in the tray. According to this, since at least a part of the circuit tube is accommodated in the tray and fixed to the support surface of the holder body, the circuit tube can be held more stably, and the dispersion of the circuit tube can be more reliably prevented. Can be prevented.

  On the other hand, the extracorporeal circuit system package of the present invention is an extracorporeal circuit system package in which the extracorporeal circuit system is accommodated in a packaging case, and the extracorporeal circuit system is placed inside the packaging case. In a state in which the holder is accommodated so as to face upward, receiving surfaces having substantially the same height as the support surface of the holder are provided on both sides.

  According to the above invention, even when the winding diameter of the circuit tube is large and protrudes from both sides of the support surface, the portion protruding from both sides of the circuit tube is supported by the receiving surface in the packing case. It is possible to prevent the circuit tube from dropping, bending, and kinking at the bottom of the packing case during impact, vibration, and long-term storage.

  According to the extracorporeal circuit system of the present invention, the circuit tube connected in advance to the apparatus main body can be attached to the apparatus main body in a compact winding shape, and packing and unloading operations can be facilitated. Further, since the circuit tube can be supported on the support surface of the holder having a relatively large area, the circuit tube can be prevented from being kinked or entangled. Furthermore, by placing the circuit tube on the support surface of the holder, the weight of the circuit tube can be received softly against impacts during transportation due to the cushioning property of the frame-shaped holder. Damage to the circuit tube can be prevented.

  On the other hand, according to the extracorporeal circulation circuit system package of the present invention, even when the winding diameter of the circuit tube is large and protrudes from both sides of the support surface, the portion protruding from both sides of the circuit tube is in the packing case. Since it is supported by the receiving surface, it is possible to prevent the circuit tube from dropping, bending, and kinking down from the packing case during transportation and shock and vibration during long-term storage.

  Hereinafter, an embodiment of the extracorporeal circuit system and the extracorporeal circuit system package of the present invention will be described with reference to the drawings.

It is used during surgery, and forms a circulation circuit that removes blood from the body, performs a predetermined treatment on the blood, and then returns the blood to the body.

  FIG. 8 shows a schematic configuration diagram of extracorporeal circulation during cardiac surgery. A blood removal catheter K1 is connected to the patient's vein, and blood containing a large amount of carbon dioxide gas is taken out of the body by this blood removal catheter K1 and sent to a reservoir 13 of the apparatus body 10 described later. The blood passage on the vein side forms a blood removal circuit C1. A blood feeding catheter K2 is connected to the patient's artery, and blood supplied with oxygen by an artificial lung 11 (described later) is returned from the outside to the inside of the body. Constitutes a blood sending circuit C2. Further, a plurality of circuits are configured such as a suction circuit C3 that is a blood passage for collecting blood that bleeds from the heart and a myocardial protection circuit C4 that administers a myocardial protective solution that prevents damage to the stopped heart tissue. The blood supply in the blood supply circuit C2 is performed by a pump unit 15 described later, and the blood supply in the blood removal circuit C1, the suction circuit C3, and the like is performed by a roller pump R.

  As shown in FIG. 1, this extracorporeal circuit system 1 (hereinafter referred to as “circulation system 1”) has a device body 10 having at least an artificial lung 11 and a circuit tube 20 connected to the device body 10. The circuit tube 20 is preconnected to the apparatus main body 10.

(See FIGS. 1 and 5).

  First, the circulation system 1 will be described. Referring also to FIG. 2, the apparatus main body 10 constituting the circulation system 1 is coaxially provided at a position adjacent to the artificial lung 11 and the oxygenator 11 having a cylindrical case shape. And a reservoir 13. A plurality of hollow fiber membranes are disposed inside the artificial lung 11 to remove carbon dioxide in the blood and supply oxygen to the blood. An arterial filter (not shown) is disposed on the outer periphery of the hollow fiber membrane built in the oxygenator 11, and a blood supply circuit C2 (see FIG. 8), which is a blood passage on the artery side, is provided by a pump unit 15 described later. ) To remove foreign substances in blood. On the other hand, the reservoir 13 is a suction circuit that is a blood passage for collecting blood flowing through a blood removal circuit C1 (see FIG. 8) that is a blood passage on the vein side and blood that bleeds from the heart when treatment is performed on the heart. This is for storing blood or the like flowing through C3 (see FIG. 8). As shown in FIGS. 2 and 7, the reservoir 13 has a cylindrical shape that gradually increases in diameter as the distance from the artificial lung 11 increases.

  The apparatus main body 10 further includes a pump unit 15. The pump unit 15 is a centrifugal pump that sends liquid by the centrifugal force of a rotating impeller, and is connected to the artificial lung 11 and the reservoir 13 via a tube, and sends blood stored in the reservoir 13 to the artificial lung 11. At the same time, the artificial lung 11 serves as an artificial heart that re-feeds blood into which the carbon dioxide gas has been removed and oxygen is added through the blood sending circuit C2.

  Each member of the apparatus main body 10 is provided with a plurality of ports (not shown) for allowing blood to flow in and out. In this circulation system 1, one end portions of a plurality of circuit tubes 20 are pre-connected (pre-connected) to the plurality of ports. The other end portions of the plurality of circuit tubes 20 are connected to the blood removal circuit C1, the blood transmission circuit C2, and the like shown in FIG. The plurality of circuit tubes 20 are appropriately combined one by one or plural pieces with one end pre-connected to the apparatus main body 10, and are wound, for example, in a ring shape to have a predetermined winding shape. It is wound on.

  In the circulation system 1 of the present invention, the holder 30 is attached to the apparatus main body 10 in order to support the plurality of circuit tubes 20 wound in a predetermined winding shape on the outer periphery of the apparatus main body 10. The holder 30 in this embodiment will be described with reference to FIG. 3. The holder 30 is, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), acrylonitrile / styrene resin (AS), acrylonitrile. / Butadiene / styrene resin (ABS), methacrylic resin (PMMA), vinyl chloride (PVC), polyamide (PA), polyacetal (POM), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polycarbonate (PC), modified It is formed from a synthetic resin such as polyphenylene ether (PPE), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), etc., and extends long along the axial direction of the device body 10 and extends in the circumferential direction of the device body 10.

The arm can be inserted into the inside or can be grasped and lifted with one hand. Further, since the holder 30 has a frame shape in which a gap is interposed, the gap and the side wall 33 serve as a cushion, and the weight of the circuit tube 20 supported by the support surface 35 is determined by the weight of the main body contact surface 31. It does not act directly on.

  Further, as shown in FIGS. 3B and 3C, the main body contact surface 31 corresponds to the shape of the reservoir 13 of the apparatus main body 10, that is, the outer peripheral shape that gradually increases in diameter as the distance from the artificial lung 11 increases. It has a three-dimensional shape. Specifically, as shown in FIG. 3 (b), the main body abutting surface 31 extends from the distal end (the end located on the oxygenator 11 side when the holder 30 is attached to the apparatus main body 10) to the proximal end. As shown in FIG. 3 (c), the curved shape gradually increases in height toward the portion, and when viewed from the side, the shape of the cylinder 13 is increased in the circumferential direction.
