Medical catheter surface coating curing machine

Abstract

The invention relates to a medical catheter surface coating curing machine which comprises a machine box. The inside of the machine box is provided with an upper support, a lower support and a test tube box containing PVP solutions. An automatic catheter lifting mechanism, a catheter rotary mechanism and a lamp box linear motion mechanism are arranged between the upper support and the lower support. The automatic catheter lifting mechanism comprises a lead screw sliding table, the catheter rotary mechanism is arranged on the lead screw sliding table and moves up and down along with the lead screw sliding table, the catheter rotary mechanism comprises multiple catheter clamps, and catheters can be detachably arranged on the catheter clamps. The lamp box linear motion mechanism comprises a lamp box. The automatic catheter lifting mechanism drives the catheter rotary mechanism to move downward, the catheters are soaked in the PVP solutions of the test tube box and ascend to the lamp box along with the automatic catheter lifting mechanism, and the lamp box is provided with an ultraviolet light source which can dry and cure the PVP solutions attached to the surfaces of the catheters. The medical catheter surface coating curing machine is easy and convenient to operate, high in automation degree, good in compatibility, good in curing effect, safe and reliable, and the catheters capable of being cured are long.

Description

[0001] technical field [0002] The invention relates to medical device processing automation equipment, in particular to a machine for automatically completing the surface coating curing of medical catheters. [0003] Background technique [0004] Medical catheters are used in a wide range, mainly used in central venous catheters for surgical operations and various intubations, various monitoring nutrition injection tubes and sewage drainage tubes for treatment and nursing, and various catheters for diagnosis and interventional therapy. While medical catheters bring convenience to clinical treatment, there are also some problems. Since the medical catheter is made of hydrophobic material, the friction force is relatively large during use, and the patient is often accompanied by burning and pain, which is likely to cause damage to the patient's blood vessels and cavity tissues, and serious complications. Therefore, the surface of medical catheters is required to have lubri...

AI Technical Summary

Problems solved by technology

However, due to the relatively high light intensity requirements for ultraviolet light when the PVP solution is cured, most of the current curing equipment for the surface coating of medical catheters can only cure shorter catheters, and most of the ultraviolet light sources use high-pressure mercury lamps, and the power consumption Larger, strong heat generation, relatively low efficiency, needs further improvement
