Abstract

The invention discloses a co-extrusion composite extrusion mold for a medical anesthetic catheter with an X-ray development line. The mold comprises a main machine barrel. A main machine barrel flangeis arranged on the outer surface of the main machine barrel, a main machine filter screen plate is fixedly installed in the main machine barrel, and a co-extrusion head front mold body is fixedly connected to one side of the main machine barrel. An co-extrusion head rear mold body is fixedly connected to one side of the co-extrusion head front mold body, an inner-layer flow distributor is arranged inside the co-extrusion head front mold body, an outer-layer flow distributor is arranged outside the inner-layer flow distributor, and a torpedo cone connector is fixedly installed inside the co-extrusion head rear mold body. According to the co-extrusion composite extrusion mold for the medical anesthetic catheter with the X-ray development line, a designed extrusion mold structure is simple,disassembly is convenient to carry out, and maintenance is convenient to carry out; the mold pressure is uniform, and no dead angle exists; a co-extrusion developer is uniform, good in coating performance and free of diffusion; and a mold runner is designed to be uniform in pressure stabilization, and it is avoided that the stability of a pipe body is poor due to material fluctuation.

Description

technical field [0001] The invention belongs to the technical field of anesthesia catheters, three-color anesthesia catheters, four-color anesthesia catheters, and five-color anesthesia catheters extrusion die molding technology, and specifically relates to a medical anesthesia catheter with X-ray development line co-extrusion composite extrusion die. Background technique [0002] From a medical point of view, the meaning of anesthesia is to temporarily lose the patient's overall or partial sensation through drugs or other methods, so as to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examination and treatment. An anesthesia catheter is one of the devices used when using or injecting anesthesia. [0003] Medical anesthesia catheter with X-ray development line co-extrusion compound extrusion die is widely used in medical equipment, medical consumables and other fields. At present, the main tube of the conventional anesthe...
