Description

Technical Field

[0001] The utility model relates to a pipeline fixer for extracorporeal circulation heart surgery, belonging to the technical field of medical equipment. Background Art

[0002] Currently, extracorporeal circulation tubes are often used in various cardiac surgeries. To prevent the tubes from falling off during surgery, a fixator is needed to fix the extracorporeal circulation tubes. However, the existing technology lacks a special fixator. Usually, a tube fixator is made by using large developing gauze to fix the extracorporeal tubes on a disposable surgical towel. This homemade fixator is made by manually weaving large developing gauze into strips, and then each tube of the extracorporeal circulation is clamped in it. This fixing method is cumbersome to operate and there is a risk of losing the gauze during surgery and damaging the integrity of the gauze. It is also not convenient for the hand-washing nurse to uniformly manage the gauze during surgery. Utility Model Content

[0003] The purpose of the utility model is to provide a tube fixer for extracorporeal circulation heart surgery, which is specially used to fix the extracorporeal circulation tube in heart surgery, so as to solve the technical problems of the existing manual fixator being cumbersome to operate and inconvenient to use.

[0004] The utility model adopts the following technical solution: a tube fixator for extracorporeal circulation cardiac surgery, which includes a long strip-shaped fixator body, and a tube clamp for clamping the cardiac surgery tube on the fixator body. The axial direction of the tube clamp extends along the width direction of the fixator body, and the tube clamps are arranged in sequence and at intervals along the extension direction of the fixator body. The tube clamps and the fixator body are both made of hard elastic materials. The tube clamp is an arc-shaped convex structure integrally provided with the fixator body. The inside of the tube clamp has a circular arc surface for clamping the tube. The internal aperture of the tube clamp is adapted to the outer diameter of the tube to be clamped, and the tube clamp has an opening on one side of the fixator body.

[0005] One side of the opening of each pipe clamp is located on the same side of the fixer body, and the arc-shaped protrusion of each pipe clamp is located on the other side of the fixer body.

[0006] The side of the holder body where the opening is provided is a flat surface.

[0007] Both ends of the fixer body are respectively provided with fixing holes.

[0008] An anti-slip structure is provided on the arc surface inside the pipe clamp.

[0009] The tube clamps include arterial tube clamps, venous tube clamps, left heart drainage tube clamps, right heart drainage tube clamps, cold can tube clamps and carbon dioxide tube clamps.

[0010] The arterial tube clamp, venous tube clamp, left heart drainage tube clamp, cold can tube clamp, right heart drainage tube clamp and carbon dioxide tube clamp are arranged in sequence on the fixator body.

[0011] The inner diameters of the arterial tube clamp and the venous tube clamp are both 10 mm, the inner diameters of the right heart drainage tube clamp and the left heart drainage tube clamp are both 5 mm, and the inner diameter of the cold tank tube clamp is 2 mm.

[0012] There are two intravenous tube clamps.

[0013] The fastener body is made of TPU material with a Shore hardness of 88 by injection molding.

[0014] The present invention provides a beneficial effect: the tube clamp is designed to be compatible with cardiac surgical tubing. During use, each tubing is individually clamped within the clamp. Because each clamp is integrally connected to the clamp body, no additional components are required, resulting in a simple overall structure and ease of use. Compared to existing tubing clamps made of gauze, the clamp is simpler and more convenient to operate, provides a secure hold, and facilitates the management of gauze during surgery by handwashing nurses, reducing the risk of gauze loss to a certain extent.

[0015] Preferably, one side of the opening of each pipe clamp is located on the same side of the fixture body, which facilitates forming one side of the fixture body into a planar structure, so that the fixture can be placed flat and remain stable during use.

[0016] Preferably, when in use, after the extracorporeal circulation tubes are clamped into the tube clamps one by one, the fixator is fixed to the towel sheet through the fixing hole with Alice forceps, which is easy to operate and facilitates intraoperative management.

[0017] Preferably, the sizes of the arterial tube clamp, venous tube clamp, left heart drainage tube clamp, right heart drainage tube clamp, cold can tube clamp and carbon dioxide tube clamp are respectively adapted to the commonly used diameters of the tubes, so as to facilitate clamping of the tubes.

[0018] Preferably, the material of the fixator is TPU with a Shore hardness of 88, and can withstand a sterilization environment below 150° C. and is reusable. BRIEF DESCRIPTION OF THE DRAWINGS
