Definitions
- the present invention relates to a medical tube clamp that is applied to a flexible tube used in the medical field and switches the tube between a communication state and a closed state.
- a flexible medical tube has been used as a tube constituting an extracorporeal circuit for body fluids such as blood, an auxiliary circuit, or an infusion line for drug solutions.
- a clamp device made of a resin molded product is used.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2003-235971
- a clamping device has a first plate-like portion and a second plate-like portion provided with pressing protrusions on respective opposing surfaces, and curved portions. It is the structure connected by. Then, the medical tube is pressed between the pressing protrusions to be held in a closed state by elastically deforming the curved portion and locking the first plate-like portion and the second plate-like portion at the approaching positions. It has become.
- the medical tube may be displaced laterally from the pressing projection and the closing may be incomplete, so that careful work is required.
- the present invention has been made against the background of the above-mentioned circumstances, and the problem to be solved is the relative displacement of the first plate-like portion and the second plate-like portion in the lateral direction, both of them. While effectively preventing any lateral displacement of the medical tube with respect to the plate-like portion, the first plate-like portion and the second plate-like portion are relatively displaced in the approaching direction between the projections for compression. Therefore, it is an object of the present invention to provide a clamp for a medical tube having a novel structure capable of quickly and reliably performing the operation of pressing and closing the medical tube.
- a feature of the first aspect of the present invention is that a pressing protrusion that presses and closes a medical tube against each opposing surface of the first plate-like portion and the second plate-like portion connected by a bending portion.
- a locking means that is formed and elastically deforms the curved portion to lock the first plate-like portion and the second plate-like portion at a mutually approaching position to hold the medical tube in a closed state.
- the first plate-like portion and the second plate-like portion protrude from one plate-like portion toward the other plate-like portion toward the side of the medical tube.
- Both side wall portions that prevent displacement and a central guide protrusion that protrudes from the other plate-shaped portion toward the one plate-shaped portion are formed, and both side surfaces of the front end of the center guide protrusion are Both side wall portions projecting toward the center when the first plate portion and the second plate portion are relatively displaced in the approaching direction.
- There the center guide projection while preventing hooking hunting to clamp medical tubing which is an inclined guide surface for entering into between the both side wall portions.
- the medical tube when the medical tube is closed, the lateral displacement of the medical tube is prevented by the side walls, so that the medical tube is reliably compressed between the pressing projections of both plate-like portions. It becomes possible to close. Moreover, even if the two plate-like portions are displaced relatively to the side, the relative displacement to the side is corrected based on the contact action between the inclined guide surface and the both side wall portions and the sliding action, and the hook is not caught. Thus, the first plate-like portion and the second plate-like portion can be brought close to each other in the original facing state. As a result, the medical tube can be surely and quickly compressed and closed between the pressing protrusions of both plate-like portions.
- a second aspect of the present invention is the medical tube clamp according to the first aspect, wherein both the side wall portions and the central guide protrusion are opposite to the curved portion rather than the compression protrusion. It is located in the opening part side.
- the effect of correcting the relative displacement in the lateral direction between the first plate-like portion and the second plate-like portion based on the guide action caused by the sliding between the inclined guide surface and both side wall portions and the effect of preventing the catch are further effective.
- the opening portion side where the relative displacement in the lateral direction becomes larger than the curved portion side It is effective to provide an inclined guide surface and both side walls.
- the medical tube clamp according to the first or second aspect wherein the one plate-like portion extends from the top of the inclined guide surface at the distal end portion of the central guide protrusion.
- the biting prevention protrusion which protrudes toward is formed.
- the biting prevention protruding piece is positioned where the first plate-like portion and the second plate-like portion are opened so as to open the mouth between the end portions on the opening portion side opposite to the curved portion.
- the biting prevention protruding piece is positioned where the first plate-like portion and the second plate-like portion are opened so as to open the mouth between the end portions on the opening portion side opposite to the curved portion.
- the medical tube clamp according to any one of the first to third aspects, wherein the one plate-like portion is open from the end on the opening side opposite to the curved portion.
- a locking plate portion rising toward the other plate-shaped portion is provided, and the other plate-shaped portion can be locked to the locking plate portion to constitute the locking means. It is.
- this aspect is suitably employed in combination with the third aspect, and includes a locking plate portion provided on one plate-like portion and a biting prevention protrusion provided on the other plate-like portion.
- the opening size on the opening side between the first plate-like portion and the second plate-like portion can be further reduced.
- the medical tube clamp according to any one of the first to fourth aspects, wherein the both side wall portions are closer to the curved portion side than the pressing projections, and the compression is performed. They are formed on the side of the opening opposite to the curved portion rather than the projecting portion.
- the lateral displacement of the medical tube is more effectively prevented by both side wall portions formed on both the curved side and the opening side of the compression projection, and the both side wall portions are Since both are formed off the pressing projection, it is possible to easily visually check the compression closed state of the medical tube by the pressing projection.
- the medical tube clamp when the medical tube is closed, the lateral displacement of the medical tube is prevented at both side walls, and the medical tube is reliably pressed between the pressing projections and closed. be able to.
- the guide action by the inclined guide surface and both side walls prevents the first plate-like portion and the second plate-like portion from being caught due to mutual lateral displacement, and brings both plate-like portions closer together to compress the medical tube. It is possible to quickly squeeze between the protrusions to make it closed.
