Antibacterial, anti-inflammatory and lubricating catheter containing natural cinnamaldehyde and preparation method thereof

Abstract

The invention relates to a preparation method of an antibacterial and inflammation preventing lubricating catheter containing natural cinnamyl aldehyde. Specifically, the preparation method comprises the steps of directly coating cinnamyl aldehyde to a latex or silica gel catheter, or uniformly adding and dispersing a certain amount of cinnamyl aldehyde and other conventional ingredients to latex or silica gel in a raw material prevulcanization step of the conventional latex or silica gel catheter, then dipping by a conventional forming process to obtain the latex or silica gel catheter containing natural cinnamyl aldehyde, and finally, forming and drying to obtain a product. The catheter prepared by the method has the advantages of antibacterial and inflammation preventing effect and lubrication, so that not only are infection of various bacteria and complications are prevented, but also the frictional force is small, therefore, pain of patients can be effectively alleviated.

Description

technical field [0001] The invention relates to a urinary catheter and a preparation method thereof, in particular to a urinary catheter containing a natural cinnamaldehyde antibacterial and anti-inflammatory lubricant and a preparation method thereof, belonging to the technical field of medical material preparation. Background technique [0002] Medically, a catheter is inserted through the urethra into the bladder to drain urine. Catheterization is divided into two types: indwelling catheterization and intermittent catheterization. The former urinary catheter remains in the patient's body all the time, and it is pulled out or replaced with a new tube regularly when the condition permits. The latter catheterizes every 4-6 hours, and the catheter is pulled out after the bladder is emptied. Its defect is: before the catheter is inserted into the patient's body, lubricant needs to be applied to the front end. Traditional softeners can easily lead to intubation difficulties, ...

AI Technical Summary

Problems solved by technology

Its defect is: before inserting the patient's body, the catheter needs to be smeared with a lubricant on the front end. Traditional softeners can easily lead to intubation difficulties, rupture the patient's urethral mucosa, cause subcutaneous hematoma, and even cause urinary salt deposition.

[0004] However, the cost of silver-coated silicone catheters is relatively high, and there are large differences among medical researchers.
