Abstract

The invention discloses a fixing device for deep vein catheterization for hemodialysis, comprising a connecting block, wherein the outer surfaces of the two connecting blocks are fixedly installed with a binding tape, the opposite surfaces of the two connecting blocks are fixedly installed with a left hinge block and a right hinge block, the opposite ends of the left hinge block and the right hinge block are hinged through a pin shaft, and the opposite ends of the left hinge block and the right hinge block are provided with a torsion device. A fixing device for inserting a deep vein catheter for hemodialysis, when in use, one end of the left hinge block opposite to the right hinge block is hinged through a pin shaft, the torsion spring on the pin shaft surface enters the socket. At that top of the torsion spring, a fixing strip at one end is driven to be inserted into the T-shape groove. At that same time, the first position bar on the bottom surface of the pin shaft is slidably inserted and connected with the inner wall of the positioning groove on the surface of the right hinge block, so that when the opposite end of the left hinge block and the right hinge block is hinged, the torsion spring is subjected to torsional force, so that the rings formed by the plurality of connecting blocks are nearly circular, so that the wound periphery is not harmed.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, more specifically, it relates to a fixing device for deep vein catheterization for hemodialysis. Background technique [0002] Traditional long-term hemodialysis deep vein catheters are generally fixed with medical adhesive tape during use, and the catheter connector is exposed to the air. As time goes on in daily life, the adhesive tape is easy to cause damage to the skin, and in Using adhesive tape at the position where the tube is placed in contact with the human body can easily cause airtightness around the wound, and at the same time, it is easy to breed some bacteria, making daily maintenance such as cleaning very inconvenient. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a deep vein catheter fixing device for hemodialysis, which has the characteristics of not hurting the skin and bei...
