Abstract

The utility model relates to a disposable double-chamber plastic catheter, which comprises an inner tube and an outer tube. The pipe wall with 0.8 to 3 centimeters distance to the front end of the sharp, round and smooth outer tube is provided with the outlet of the inner tube. The other side corresponding to the pipe wall of the outlet of the inner tube is provided with a liquid discharging opening. The penetration outlet of the inner tube is arranged on the tail end of the outer tube. The external diameter of the disposable double-chamber plastic catheter is smaller than the external diameter of the rubber catheter in the model of fr 12 but the inner diameter of the former is obviously larger than the latter. More than 50 instances are provided for clinical application. The washing result of urinary bladders is satisfactory. No complication appears.

Description

Disposable double-chamber plastic catheter

This utility model provides a kind of disposable two-chamber plastic catheter, belongs to medical apparatus and instruments.

At present, rubber urinary catheter is still adopted in the bladder irrigation treatment during urinary system is clinical.This urethral catheterization body is more thick and stiff, and zest is big, is easy to cause illness such as urinary tract infection, mucous membrane of urethra damage when bladder irrigation.

Above-mentioned deficiency at existing rubber urinary catheter, the purpose of this utility model provides a kind of tube wall smooth pliable, the body external diameter is little, and intubate is smooth, and drainage effect is good, the patient does not have sense of discomfort, the disposable two-chamber plastic catheter that injury of urethra and complication obviously reduce.

The purpose of this utility model realizes by following technical measures.

Disposable two-chamber plastic catheter is made of interior pipe and outer tube.On the tube wall of 0.8-3 centimetre of the round slick outer tube front end of point interior pipe outlet is set, corresponding interior tube wall opposite side of managing outlet has leakage fluid dram, and the export of interior pipe is opened in the outer tube tail end.

Disposable two-chamber plastic catheter is made by polrvinyl chloride.

In clinical, use disposable two-chamber plastic catheter and carry out bladder irrigation and prepare identical with the closed irrigation.Flush fluid for vesica urinaria is connected with pipe (input pipe) in it by transfusion device, and plastic outer tube (discharge pipe) is connected with the draining pipe system and is placed under patient's bed.The bladder irrigation operation is carried out routinely.Flush fluid for vesica urinaria continues to splash into from input pipe, continues to flow out from discharging conduit system, and be continual, whole system is lasting airtight aseptic.

Disposable two-chamber plastic catheter external diameter is little than fr12 rubber urinary catheter external diameter, and internal diameter is but significantly greater than the latter.

Example surplus the clinical practice 50, the bladder irrigation effect is satisfied, and none example is inferior to develop complications, and uses the plastic tube of different-diameter can produce serial two-chamber plastic catheter.

Because the bladder irrigation process is lasting airtight aseptic, avoided polluting and infecting.Flush fluid for vesica urinaria continues to splash into from input pipe, continues to flow out from discharging conduit system, can long-time continuous carry out bladder irrigation, also can carry out a plurality of patients' bladder irrigation simultaneously.Input pipe is regulated flushing speed with discharging all available transfusion control table of conduit system, does not need special messenger's nursing procedure, has reduced workload.

Accompanying drawing is the organigram of disposable two-chamber plastic catheter, below in conjunction with accompanying drawing, further narrates technical characterictic of the present utility model by embodiment.

External diameter is that 4.0 millimeters, 0.5 centimetre of wall thickness, long 40.0 centimetres of pvc tubes are outer tube (discharge pipe).The solid slick semiellipse shape of 0.5-0.6 centimeter length is made on its top.One 0.4 * 0.6 centimetre of fusiformis side opening---leakage fluid dram 2 is arranged on the plastic tube sidewall in the 1.0-2.0 cm range of distance top, one 2.0 * 1.5 millimeters side openings (interior pipe outlet) are being arranged on the offside tube wall of leakage fluid dram, and exporting 1 homonymy at interior pipe has a side opening on 5.0 centimetres of plastic tube walls of plastic tube tail end.Interior pipe (input pipe) is 1.5 millimeters of diameters, long 50 centimetres of pvc tubes.Place outer tube 3 intracavity, pipe outlet in the front portion connects, the rear portion passes from the tail end side opening.In the sealing that is adhesively fixed of pipe and outlet of interior pipe and tail end side opening contact position, and interior pipe is alignd with outer tube wall in interior pipe exit, make a slick front cover.Interior pipe tail end inserts one No. 7 or No. 9 injection needles 4.

Claims (2)

1, a kind of disposable two-chamber plastic catheter is characterized in that disposable two-chamber plastic catheter, is made of interior pipe and outer tube; On the tube wall of 0.8-3 centimetre of the round slick outer tube front end of point interior pipe outlet is set, corresponding interior tube wall opposite side of managing outlet has leakage fluid dram, and the export of interior pipe is opened in the outer tube tail end.

2, disposable two-chamber plastic catheter according to claim 1 is characterized in that:

One 0.4 * 0.6 centimetre of fusiformis side opening is arranged on the plastic tube sidewall in the 1.0-2.0 cm range of distance top, on the offside tube wall of leakage fluid dram, one 2.0 * 1.5 millimeters side openings are being arranged.
