患者の肺に空気を供給するため広く使用されている。[Prior Art 1] Ventilation tubes are widely used to supply air to the lungs of unconscious patients, such as injured people and patients undergoing surgery.

利用される。In order for the vent tube to act on and cover the trachea in the intended manner, the vent tube must be properly attached to the trachea and air must be forced through the tube into the trachea. However, properly inserting the tube is an extremely difficult task, and it is possible to lose sight of the surgically prepared opening in the trachea during the insertion procedure, resulting in incorrectly guiding the vent tube device into the surrounding tissue. Failure to properly insert the vent tube creates personnel problems and has dangerous consequences for the patient.1 Otorhinolaryngologists, thoracic surgeons, membranous surgeons, and other clinical specialists may experience difficulty in performing the insertion procedure. I have experienced it. To assist the clinician, various guides, such as stylets or obturators, are available to the clinician to guide and assist in placing such a tube in a patient's trachea.

の管の共通の特徴は、套管部分の一定半径の構造である
。一定半径の套管とは先端と後端との間に連続した曲面
を有づる套管と定義する。Obturators used to guide fully bent or polymeric vent tubes are described in Silley et al., US Pat. No. 3,088,466 and US Pat. No. 3,659,612. A common feature of these tubes is the constant radius construction of the cannula section. A cannula with a constant radius is defined as a cannula having a continuous curved surface between the leading end and the trailing end.
栓子が套管内に容易に挿入しうるばかりでなく仲人が完
了した後容易にかつ安全に除去しうろことは、挿入操作
において重要である。It is important in the insertion operation that the obturator not only be easily inserted into the cannula, but also be easily and safely removed after the intervention is completed.
一定半径の套管を有する通気管に使用された栓子を除去
することは、栓子が曲率半径に従って容易に引出される
ため、■大な問題を生じない。Removing an obturator used in a vent tube with a cannula of constant radius does not pose a major problem since the obturator is easily withdrawn according to the radius of curvature.

套管から栓子を引出すことは一層困難な仕事である。However, many flexible vent tubes in use today are constructed with a cannula of varying radius. A typical such stopper T has at least two substantially straight tubular sections J3 and a curved cannula section. The curves of the arcs are angled at or near right angles.
The I-line section has a considerable length. It is a more difficult task to withdraw the obturator from the cannula, which is not constant.

は、套管および栓子の湾曲した構造を維持する力にうち
勝たなければならないため、困難である。Cox U.S. Pat. No. 4,471,776 discloses an example of a vent tube having an obturator with an adjustable shape. This obturator has a pJ flexible shaft in which the obturator placed inside the tube is placed flush with the tube in the desired curved shape. However, removing the obturator from the vent tube is difficult because the forces that maintain the curved configuration of the cannula and obturator must be overcome.

。Wire-type guide devices are most commonly used with medical devices that are extremely long in length compared to their diameter, which is typically very small. The spring action of such small diameter guide wires is difficult to overcome when the action is applied to a typical imitation of a ventilator or endotracheal tube.

条片部材にほぼ垂直の多数のセグメントを描えている。[a+ SUMMARY OF THE INVENTION] The above and other objects provide for an insufflation tube for insertion into the trachea of a patient having a single piece, flexible member with a distal end, a posterior end and a shaft portion extending therebetween. This is achieved by the structure of the analyte used. The shaft device can define a generally flat strip member and a number of segments generally perpendicular to the flat strip member.

置を通る閉塞しない空気通路が確保される。Due to the structure and material properties of the present invention, when inserted into or removed from the cannula, the cannula easily deforms within the axis of the curved portion at the hinge portion, without applying forces that change the shape of the cannula. do. At the same time, when placed within the tube, the multiple segments allow the probe to substantially occupy the interior of the cannula, thereby maintaining the shape of the tube during insertion. Thus, during insertion - once in place in the patient's trachea, any deformation of the tube will prevent occlusion or collapse of the tube, ensuring an unobstructed air passage through the vent tube device.

通気管装置の外形との間に確保される。The construction of the probe of the present invention substantially resists compressive forces, which typically occur in flexible wire stylet obturators or strap-like plastic streamlined prior art devices where the cannula is completely occupies the obturator tip, allowing the obturator tip to be pushed back and complicating the insertion operation due to the lack of a smooth transition from the obturator tip to the outside diameter of the vent tube. In the device of the invention, therefore, a smooth transition is ensured between the probe tip portion and the contour of the vent tube device.

The tip member 16 projects beyond the end 22 of the cannula 20. The tip member 16 has a bullet-cone shape to facilitate guidance of the vent tube during the insertion operation. As can be seen from FIGS. 3 and 4, the diameter of the multiple segments 14 corresponds approximately to the inner diameter of the cannula 20. Thus, when installed within a tube, the stem occupies substantially the entire interior of the cannula 20, allowing the tube to maintain its shape during insertion.

。Due to the multiple hinge structure and the old bone quality of the PlasDeck material, the trunk 10 easily curves only in the radial direction of the cannula 20 within the axis of the curved tube section 36, thereby making it easier to insert into the vent tube 100 and It can be taken out. These features of the present invention are particularly important and advantageous during withdrawal of the trunk from a cannula of variable radius because the force required to pull the trunk out of the VW is significantly reduced.

からの引出しを容易にしている。The hinge-like structure allows the end to be highly flexible within the axis of the 1:tFRII#1 portion. The multiple segments of the obturator extend substantially within the tube to maintain the integrity of the vent tube, while also facilitating bending of the vent tube during entry and exit from the cannula. The obturator tip has a line part that absorbs tube deformation, and a streamlined tip shape that affects the shape of the tip.
MIIIR is carried out with the tolerance of the tester size without any deviation. A handle projecting beyond the connector facilitates withdrawal of the obturator from the cannula.

る栓子を得ることができる。ADVANTAGEOUS EFFECTS OF THE INVENTION By constructing the obturator device as a single piece, plastic flexible piece with a number of segments and a number of hinge members provided between the segments, the obturator device has a non-uniform radius. It can be easily inserted and safely removed through straight and curved sections of the cannula of the vent tube, maintains the cannula's shape during the insertion operation and prevents lff+ plugging, crimping and deformation of the cannula, and Obturators that ensure an unobstructed air passage can be obtained.
