Abstract

The invention discloses a method for preparing a secondary-forming oxygen pipe. The method comprises the steps of primary forming: extruding and forming an oxygen pipe core into a required length; secondary forming: inserting a mold core in a five-petal flower mode into the extruded and formed oxygen pipe core; and carrying out vertical forming to the oxygen pipe core inserted with the mold core in a mould of which the shape is matched with that of the oxygen pipe. One oxygen pipe of which the connection tension is more than 5Kgf is produced by strictly controlling the size and the shape of the process flow injection molding, the oxygen conveying activity is carried out under the severe conditions (such as earthquake and flood-affected areas), the oxygen pipe is not pulled cut, and a high-quality medical product is provided for the large-scale rescue.

Description

[0001] This application is a divisional application of Chinese patent application CN201010297307.4. technical field [0002] The invention relates to a medical product and the technical field of a medical oxygen tube, in particular to a secondary molding oxygen tube and a secondary molding process. Background technique [0003] Oxygen tubes are pipes that connect oxygen cylinders or oxygen machines to deliver oxygen to those who need oxygen. Due to the different specifications of oxygen cylinders, the amount and pressure of oxygen required for various patients are also different. Most of the oxygen tubes in hospitals are like industrial ones. Like cables, they are purchased in rolls, and each purchase is relatively large. If you have to purchase oxygen tubes of different specifications to meet different oxygen delivery pressures or other requirements, it will be a waste of medical costs. [0004] In addition to the use of oxygen tubes in hospitals, oxygen tubes are also used...
