Problems solved by technology

In the known technology, the long round hole on the venous cannula is directly punched out on the tube wall through the cylinder-driven punching machine. Since the hole punched out by the above-mentioned punching machine will form a right-angled edge on the outer wall of the tube, that is, a very sharp edge is formed. When the medical staff inserts the venous catheter into the patient's body, it will damage other organs of the patient, which not only brings a lot of trouble to the medical staff's operation, but also causes unnecessary pain to the patient

Abstract

The invention relates to a hot air type perforating machine, which is characterized by comprising a base; a core rod support frame and an electric cabinet are arranged at one end of the base, and a gripping component for clamping and fixing pipe fittings is arranged at the other end of the base through a gripping bracket; a perforating mechanism is arranged above the base corresponding to the gripping component; and a heating device is further arranged on the base positioned on one side of the perforating mechanism. The hot air type perforating machine has the advantages that air is heated on a perforating part firstly and then perforating is carried out before a venous cannula is perforated so that a concave annular ring is formed on a perforated surface after heating; the aperture is round and smooth so that a very sharp aperture is prevented from being formed on the outer wall of the body of the venous cannula on the traditional perforating machine; and moreover, when the venous cannula is inserted in the body of a patient by medical staff, other visceral organs of the patient cannot be injured, and the safety performance of the venous cannula when in use is further improved.

Description

technical field [0001] The invention belongs to the technical field of medical tube body processing, in particular to a hot air punching machine. Background technique [0002] At present, in the surgical operation process, the extracorporeal blood circulation technology has been widely used in clinical practice by taking human blood (vein) out of the body for gas exchange into arterial blood and then reinfusing it into the body to assist the success of the operation and achieve the purpose of treatment. Such as organ transplantation, respiratory surgery, neurosurgery, emergency rescue and other operations, especially in cardiovascular surgery, about 50% of them are completed with the assistance of extracorporeal circulation. The vena cava cannula is a special drainage cannula that is inserted into the human venous blood vessel when cardiology surgery establishes extracorporeal circulation. The vena cava cannula is a straight-through tube body with a porous interface at the f...
