(57) [Summary] [Purpose] To provide a safe suction catheter that does not damage the mucous membrane in the suction hole of the suction catheter. [Structure] On the side of the pipe tip of the suction catheter, the pipe outer peripheral surface (1) and the suction hole wall surface (2) have an obtuse angle, and a conical suction hole penetrating from the pipe outer peripheral surface (1) to the hollow portion (5). (3) is provided.
Description
【０００１】[0001]
この考案は、医療用吸引カテーテルのパイプ先端部側面に、パイプ外周面と吸 引孔壁面が鈍角となる吸引孔を設けた吸引カテーテルに関するものである。 The present invention relates to a suction catheter in which a suction hole having an obtuse angle between the outer peripheral surface of the pipe and the wall surface of the suction hole is provided on the side surface of the pipe tip portion of the medical suction catheter.
【０００２】[0002]
従来、患者の体内より羊水、粘液、血液などの体液を、体外に排出する場合に 用いられる吸引カテーテルの吸引孔は、体内に挿入するパイプ先端部側面に設け られており、その形状は、パイプ外周面より中空部に、垂直に貫通した円筒状で 、吸引孔口が角になっていた。 Conventionally, the suction hole of a suction catheter used to drain body fluids such as amniotic fluid, mucus, and blood from the patient's body is provided on the side surface of the tip of the pipe to be inserted into the body. It had a cylindrical shape that penetrated vertically from the outer peripheral surface to the hollow portion, and the suction hole mouth was angled.
【０００３】[0003]
これは次のような欠点があった。 吸引カテーテルにより、体内から羊水、粘液、血液などの体液を吸引排出する場 合、体内に挿入したパイプ先端部側面の吸引孔が、粘膜に接触したとき、体液の 他に粘膜をも吸引し、吸引した状態でカテーテルを挿入したり、引き抜くなどの とき、角状の吸引孔で粘膜を損傷してしまうことが起きがちであった。 本考案は、これらの欠点を除くためになされたものである。 This had the following drawbacks. When aspirating the body fluid such as amniotic fluid, mucus, blood, etc. from the body with the suction catheter, when the suction hole on the side of the tip of the pipe inserted into the body contacts the mucous membrane, it also suctions the mucous membrane in addition to the body fluid. When inserting or withdrawing a catheter with suction, it was easy for the angular suction holes to damage the mucous membrane. The present invention has been made to eliminate these drawbacks.

吸引カテーテルのパイプ先端部側面に、パイプ外周面（１）と吸引孔壁面（２ ）が鈍角となるパイプ外周面（１）から中空部（５）に貫通した円錐状の吸引孔 （３）を設ける。 本考案は、以上のような構成からなる吸引カテーテルである。 A conical suction hole (3) penetrating the hollow portion (5) from the pipe outer peripheral surface (1) where the pipe outer peripheral surface (1) and the suction hole wall surface (2) have an obtuse angle is formed on the side surface of the pipe distal end portion of the suction catheter. Set up. The present invention is a suction catheter configured as described above.
【０００５】[0005]
吸引孔（３）が粘膜（４）を吸引した状態で、吸引カテーテルを挿入したり、 引き抜いたりしても、吸引孔口（６）は粘膜（４）の表面を、円滑に移動する。 Even if the suction catheter is inserted or withdrawn while the suction hole (3) sucks the mucous membrane (4), the suction hole mouth (6) smoothly moves on the surface of the mucous membrane (4).
【０００６】[0006]
以下、本考案の実施例について説明する。 吸引カテーテルの体内に挿入されるパイプ先端部側面に、適当な大きさのパイプ 外周面（１）と吸引孔壁面（２）が鈍角で、かつパイプ外周面（１）から中空部 （５）に貫通した円錐状の吸引孔（３）を数個設ける。 本考案は、以上のような構成からなる吸引カテーテルである。 Embodiments of the present invention will be described below. On the side surface of the tip of the pipe to be inserted into the body of the suction catheter, the pipe outer peripheral surface (1) of appropriate size and the suction hole wall surface (2) have an obtuse angle, and from the pipe outer peripheral surface (1) to the hollow portion (5). Several conical suction holes (3) are provided therethrough. The present invention is a suction catheter configured as described above.
【０００７】[0007]
この吸引カテーテルは、吸引中の操作上、吸引孔で粘膜を損傷することがない ため、医療従事者が安心して体液の排出行為を患者に対しおこなえ、医療上にお いてきわめて有効である。 Since this suction catheter does not damage the mucous membrane at the suction hole during the operation during suction, the medical staff can perform the discharge of body fluid to the patient with peace of mind, and it is extremely effective medically.
