Description

Medical tube clamp with U-shaped groove

Technical Field

The invention relates to a pipe clamp, in particular to a medical pipe clamp with a U-shaped groove, which is applied to controlling the circulation and the cut-off of a medical hose in a medical process.

Background

In medical procedures, flexible medical tubes are often used as delivery tubes, constituting extracorporeal circulation circuits or infusion lines for assisted circulation of body fluids such as blood or drug solutions, etc. Flexible medical tubing is used with a clamp device molded from resin to allow the medical tubing to be closed in the desired position as needed. The current clamping device has poor reliability and risks that the medical tube cannot be completely disconnected. Chinese patent application No.: 201280009329.3, "medical tube clamp", comprising on opposite surfaces a first plate part and a second plate part of a compression protrusion for closing a medical tube, on both sides, side walls protruding from the first side to the second side, and also a central guide protrusion protruding from the second side to the first side. The tip side of the central guide projection forms an inclined guide surface projecting toward the center, and when the first plate part and the second plate part are moved relative to each other to become closer to each other to thereby pinch the medical tube, the lateral displacement of the first plate part and the second plate part is regulated by the sliding of the wall parts and the inclined guide surfaces on both sides, with the central guide projection interposed between the wall parts on both sides. The patent application has the advantages of compact structure, convenient operation and quick stop. However, generally, one end of the flexible medical tube is connected to the medical equipment, and the other end is connected to the human body; the medical tube clamp with the structure can be inserted into the tube through the tube head part in advance and installed, and the medical tube clamp cannot be installed at any middle position of the medical tube and cannot be installed in the medical tube afterwards. The above patent application fails to address this need if a hose is to be fitted with a clamp during a medical procedure, or if an existing hose fails and the clamp is to be replaced immediately.

Disclosure of Invention

In order to further improve the series of test tube racks, the invention seeks to provide a medical tube clamp with a U-shaped groove, which can be installed at any middle position of a medical hose in the medical treatment process afterwards.

The technical scheme adopted by the invention for solving the technical problems is as follows: the medical tube clamp with the U-shaped groove is characterized in that the U-shaped groove is formed in the side face of a tube clamp body, and any middle section of the hose can be placed in the U-shaped groove; a pawl is arranged at the front end of a corner on the left side of the pipe clamp body; the front end of the corner on the right side of the pipe clamp body is connected with a hinged plate through a rotary hinge; a positioning groove is arranged on the connecting section below the left and right turning parts, and a positioning table of the lower tooth body is arranged in the positioning groove; the middle part of the lower tooth body is provided with lower teeth, and the middle part of the lower surface of the hinged plate is provided with upper teeth. The pipe clamp body and the hinged plate are manufactured into a whole, the thickness of the material at the position of the rotary hinge is smaller than that of the hinged plate, and the deformation of the material at the position of the rotary hinge is used as a hinge when the pipe clamp body is pressed downwards; or the pipe clamp body and the hinged plate are of a split structure, and a rotating shaft is additionally arranged at the hinged position. The turning parts of the left side and the right side are connected with elastic blocking pieces. The upper surface of the front end of the hinged plate is provided with a concave arc pressing point.

The application method of the medical tube clamp with the U-shaped groove comprises the steps of installing the middle section of a hose from the middle section of the hose, placing the middle section of the hose into the U-shaped groove of a tube clamp body, pushing the hose towards a hinged plate direction by using fingers to extrude a space below the hose, inserting lower teeth inwards from the middle of the left and right turning positions of the tube clamp body until a positioning table is placed in a positioning groove, installing the lower teeth in place, releasing the fingers to enable the hose to fall back on the lower teeth, and installing the medical tube clamp with the U-shaped groove; when the hose needs to be stopped, the medical tube clamp with the U-shaped groove is held by a hand, the thumb presses the concave arc pressing point downwards to enable the hinged plate to rotate around the hinge, when the front end of the hinged plate rotates to the pawl, the pawl is pushed backwards, when the hinged plate continues to rotate to a position lower than the hook tip of the pawl, the pawl returns forwards by utilizing the elasticity of materials and the elasticity of a turning structure, so that the pawl hooks the end of the hinged plate, at the moment, the distance between the upper teeth and the lower teeth is minimum, and the upper inner wall and the lower inner wall of the hose can be meshed together; when the gap between the upper teeth and the lower teeth is less than twice the wall thickness of the hose, the hose is stopped.

The medical tube clamp with the U-shaped groove has the advantages that the tube clamp can be installed at any middle position of the medical hose in the medical treatment process afterwards. For example, when one end of the flexible medical tube is connected to medical equipment and the other end of the flexible medical tube is connected to a human body, the medical tube clamp with the U-shaped groove can be installed at the middle section of the hose randomly according to needs in the medical process, and a convenient and reliable tube clamp is provided for the medical process.
