しかしながら、前述したような従来の医療用吸引注入器具は、未だ解決すべき次のような問題がある。
（１）従来の医療用吸引注入器具は、内部を円形貫通孔とする筒状の筒体の先端面を平面形状や、先端面の外周囲の角部を丸くしたＲ面形状としているので、吸引時に口内や、体内の皮膚、肉片、臓器等に接触して空気の流れを遮断し、真空ポンプの負圧が皮膚、肉片、臓器等に直接作用して貫通孔に強く吸込まれることで、皮膚、肉片、臓器等を傷付けることが発生している。特に、筒状の筒体の先端面の内壁側の角部が直角である場合には、皮膚、肉片、臓器等を傷付け易くなっている。また、筒状の筒体の先端の開口部が皮膚、肉片、臓器等で塞がれてしまう場合には、吸引が停止することとなり、医療用吸引注入器具の役割を発揮できなくなってしまっている。
（２）従来の負圧で作用する弁を設けた単数、又は複数個の開口部を筒状の筒体測部に設けた医療用吸引器具は、複雑な構造となるので、弁部の清浄性及び滅菌状態を維持することが難しく、医療用としては不向きである。また、この医療用吸引器具は、負圧のみで作用する弁で構成されているので、洗浄液や、生命維持液等の注入用として用いることができない。更に、この医療用吸引器具は、複雑な弁を設けることで、高価なものとなっている。
（３）従来の吸引カテーテルや吸引チューブを先端に取り付ける医療用吸引器具は、皮膚、肉片、臓器等の吸引や、詰まりの防止が施されていないので、皮膚、肉片、臓器等に傷を付けやすくなっている。また、例え、医療用吸引器具に詰まりの検知手段を設けたとしても、詰まった場合の処置を施さなければならず、その間の人体への影響が大きい。また、この医療用吸引器具は、吸引のみが行えるものであるので、洗浄液や、生命維持液等の注入用として用いることができない。更に、この医療用吸引器具は、複雑な弁を設けることで、高価なものとなっている。
本考案は、かかる事情に鑑みてなされたものであって、直管状の筒体を口内や、体内に挿入して吸引した時の詰まりや、皮膚、肉片、臓器等の吸引を防止して容易に取り扱うことができ、簡単に洗浄液や、生命維持液等の注入用として切り替えることができる安価な医療用吸引注入器具を提供することを目的とする。 However, the conventional medical suction injection device as described above still has the following problems to be solved.
(1) Since the conventional medical suction and injection device has a cylindrical shape with a circular through-hole inside, the tip surface of the cylindrical tube has a planar shape or a rounded outer peripheral corner of the tip surface. When inhaling, it touches the mouth, skin, flesh, organs, etc. in the body to block the flow of air, and the negative pressure of the vacuum pump acts directly on the skin, flesh, organs, etc. Injuries, skin, flesh, organs, etc. have occurred. In particular, when the corner on the inner wall side of the distal end surface of the cylindrical tube body is a right angle, the skin, meat pieces, organs and the like are easily damaged. In addition, if the opening at the tip of the cylindrical tube is blocked by skin, meat pieces, organs, etc., the suction will stop and the role of the medical suction injection device will no longer be demonstrated. Yes.
(2) A conventional medical suction instrument provided with a single or a plurality of openings provided with a valve that operates at a negative pressure in a cylindrical tube measuring part has a complicated structure. It is difficult to maintain the sexiness and sterilization state, and it is not suitable for medical use. Moreover, since this medical suction instrument is composed of a valve that operates only under negative pressure, it cannot be used for injecting cleaning liquid, life support liquid, or the like. Furthermore, this medical suction instrument is expensive due to the provision of complex valves.
(3) A conventional suction device with a suction catheter or suction tube attached to the tip does not prevent skin, meat pieces or organs from being sucked or clogged. It has become easier. Moreover, even if a clogging detection means is provided in the medical suction device, it is necessary to take measures when clogged, and the influence on the human body during that time is great. Moreover, since this medical suction instrument can only perform suction, it cannot be used for injection of cleaning liquid, life support liquid, or the like. Furthermore, this medical suction instrument is expensive due to the provision of complex valves.
The present invention has been made in view of such circumstances, and is easy to prevent clogging and suction of skin, meat pieces, organs, etc. when a straight tube is inserted into the mouth or body and sucked. It is an object of the present invention to provide an inexpensive medical suction injection device that can be handled easily and can be easily switched for injection of a cleaning liquid, a life support liquid or the like.
