Abstract

The invention discloses the manufacture method of a kind of catheter, belong to medical material tech field, including herein below: a. acetone and ethanol are pressed 1:1 and formed solvent, take PLGA and are dissolved in described solvent；B. adding nitrofural, mixing is dissolved, centrifugal after take supernatant to container, catheter is immersed in container in supernatant, uniformly pulls out, put in drying baker and be dried until solvent volatilizees completely under room temperature；It is immersed in 15min in the hydrogen peroxide liquid that concentration is 3% the most again.Prevention short-term indwelling catheter infects, with low cost, and manufacture method is simple, and Production Time is short.

Description

The manufacture method of catheter
Technical field
The present invention relates to medical material tech field, in particular to the manufacture method of a kind of catheter.
Background technology
Catheter is mainly used in clinical apoplexy, fracture and critically ill patient and is detained urethral catheterization, is medical treatment most-often used in hospital One of apparatus, the inpatient of about 25% uses catheter between demurrage.In use, due to various factors, often The urinary tract infection caused along with conduit.Periodically carrying out urethral orifice cleaning and sterilization to stop antibacterial to invade is can to take at present Prevention method, antibacterial, once enter urethral orifice, protects inefficacy.
Summary of the invention
It is an object of the invention to provide the manufacture method of simple, with low cost, the most antibacterial a kind of catheter, with Solve the problems referred to above.
For realizing the object of the invention, the technical scheme of employing is: the manufacture method of catheter, including herein below:
A. 1:1 composition solvent pressed by acetone and ethanol, takes Poly(D,L-lactide-co-glycolide and is dissolved in described solvent；
B. adding nitrofural, mixing is dissolved, centrifugal after take supernatant to container, catheter is immersed in container in supernatant, Uniformly pull-out, puts in drying baker and is dried until solvent volatilizees completely under room temperature；
It is immersed in 15min in the hydrogen peroxide liquid that concentration is 3% the most again.
Further, the dried catheter of step b is dipped to by ketopyrrolidine, dehydrated alcohol, polyurethanes again In the coating solution of composition；Oven for drying it is taken out to after immersion.
Further, after step c, conduit takes out from hydrogen peroxide liquid, extracts sterile physiological with disposable syringe Saline 20mL respectively rinses 10mL along inside and outside tube wall.
The invention has the beneficial effects as follows, with Poly(D,L-lactide-co-glycolide as carrier, nitrofural is antibiotic substance, The novel urinary catheter using dip-coating czochralski method development achieves sustained drug release effect, is used for preventing short-term indwelling catheter to infect, cost Cheap, manufacture method is simple, and Production Time is short.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
The manufacture method of the catheter that the present invention provides, including herein below:
A. 1:1 composition solvent pressed by acetone and ethanol, takes Poly(D,L-lactide-co-glycolide and is dissolved in described solvent；
B. adding nitrofural, mixing is dissolved, centrifugal after take supernatant to container, catheter is immersed in container in supernatant, Uniformly pull-out, puts in drying baker and is dried until solvent volatilizees completely under room temperature, centrifugal rotational speed 3000r/min；
It is immersed in 15min in the hydrogen peroxide liquid that concentration is 3% the most again.
Hydrogen peroxide has killing action to bacterial propagule, virus, fungus, reduces the clump count in conduit.After sterilization Conduit takes out from hydrogen peroxide liquid, preferably respectively rinses along inside and outside tube wall with disposable syringe extraction physiological saline solution 20mL 10mL, to reduce the stimulation to skin mucosa.
Conduit needs before immersing supernatant to clean.The dried catheter of step b is dipped to by ketopyrrolidine, anhydrous second again In the coating solution of alcohol, polyurethanes composition；It is taken out to oven for drying after immersion, enough makes the catheter produced possess super The effect of lubrication, so easy and convenient when inserting catheter, to alleviate patient painful.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area For art personnel, can there be various modifications and variations in the spirit and principles in the present invention, the modification of these equivalents or replacement etc., Within being all contained in protection scope of the present invention.

Claims (3)
