Embodiment 1

[0029] like figure 1 As shown, a kind of gold-plastic welded steel wire-reinforced tracheal intubation manufacturing process of the present invention, the manufacturing process is as follows:

[0030] Step 1, cutting: cutting the extruded tracheal intubation tube body to a semi-finished tube body of the length required by the standard specification.

[0031] Step 2, assemble the stainless steel wire spring: connect the two ends of the semi-finished pipe body to the inflatable joint, fill the semi-finished pipe body with high-pressure air through the inflatable joint, so that the inner diameter of the semi-finished pipe body expands and increases, and the inflatable joint is removed from the semi-finished pipe body. After the two ends are removed, the stainless steel wire spring is threaded into the inside of the semi-finished pipe body, so that the stainless steel wire spring is in a smooth and natural bounce state, and the stainless steel wire spring is located in the middle ...

Embodiment 2

[0043] like figure 1 and figure 2 As shown, a kind of gold-plastic welded steel wire-reinforced tracheal intubation manufacturing process of the present invention, the manufacturing process is as follows:

[0044] Step 1, cutting: assemble the extruded endotracheal tube body to the automatic feeding mechanism of the automatic cutting machine, set the cutting parameters and start the cutting machine, and cut the tube body to the length required by the standard specification For the semi-finished pipe body, the cutting parameters are set as follows: the cutting length is 36CM, and the cutting speed is 1m / s.

[0045] Step 2: Assemble the stainless steel wire spring: Connect the two ends of the semi-finished pipe body to the inflatable joint, fill the semi-finished pipe body with high-pressure air with a pressure of 0.4-0.6 MPa through the inflatable joint, and keep the pressure for 1 second, so that the semi-finished pipe body The inner diameter of the semi-finished pipe expan...

Abstract

The invention discloses a manufacturing process of a metal-plastic welded steel wire reinforced tracheal intubation tube. The manufacturing process is as follows: Step 1, cutting a semi-finished tube body; Step 2, passing a stainless steel wire spring to the semi-finished tube body Inside; step 3, set the welding parameters of the welding equipment, contact the welding conductive electrode with the ends of the stainless steel wire spring at both ends, and install the semi-finished pipe body equipped with the stainless steel wire spring in the pressing mold; step 4, start welding Equipment, first perform heating pre-welding, and then perform stable welding. After completion, turn off the welding equipment; step five, cooling: after the welding operation is completed, use compressed cold air to cool the semi-finished pipe body and the pressing mold; step six, welding quality inspection . Through the manufacturing process disclosed by the present invention, the stainless steel wire spring and the tube body of the trachea intubation can be quickly welded together, and the cost is significantly reduced compared with the traditional inner dipping process, and it has the advantages of high pass rate, low energy consumption, clean and environment-friendly.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a manufacturing process, in particular to a manufacturing process of a metal-plastic welded steel wire reinforced tracheal intubation tube. Background technique [0002] Endotracheal intubation is an important medical device used in general anesthesia, cardiopulmonary resuscitation, and rescue of critically ill patients with respiratory dysfunction. The outer surface of the traditional endotracheal tube is provided with an inflatable bag. The edge is airtightly connected with the tube body and communicated with one end of the intake tube inlaid on the outer wall of the tube, the other end of the intake tube is communicated with the intake valve, the air bag is used to seal the airway, and the endotracheal tube lumen is connected with the ventilator , for patient breathing and oxygen supply. Endotracheal intubation refers to the use of a special endotracheal tube and intubation...
