CN2184450Y - Soft urine tube - Google Patents

Abstract

The utility model relates to a soft urine tube. The various urine tubes which are used in the clinical medicine at present are the column shape and are hard to some extent, so the urine tubes stimulate the mucous membrane of the urethra, make the secretion occlusion and the infection. The utility model is characterized in that the interior of a thin-wall hollow column-shaped urine tube which is connected with a solid-core bend head as the integration is provided with a solid-core column tube which is capable of being inserted and taken out. The solid-core column tube is a little shorter than the hollow urine tube; two holes are arranged on a urine tube wall of a connecting end between the hollow urine tube and the solid-core bend head. The urine tube is provided with an air bag whose tail end is connected with an air bag tube opening with a piston; the utility model is suitable for the urethral catheterization in the clinical medicine.

Description

Soft urine tube

This utility model relates to the urinary catheter that a kind of clinical medicine is used for urethral catheterization.

No matter its material is rubber, latex or silica gel to the now clinical urinary catheter that is used for urethral catheterization, its structure is from the near-end to the far-end, interior external diameter all is to wait slightly, be cylindric and have certain rigidity, through settling stimulation and the infection that almost all brings urethra after the use, weight person causes more serious poisoning symptom and urethra complication, produces adverse consequences.

The purpose of this utility model is to provide a kind of and can significantly alleviate the silting up and infect of the stimulation of urethra and secretions for overcoming above-mentioned weak point of the prior art, makes the more efficiently safe soft urinary catheter of urethral catheterization.

The purpose of this utility model can reach by following measure: this utility model includes a solid elbow, it is characterized in that having one to be connected into the whole hollow urinary catheter of thin wall cylindrical shape with solid elbow, in the hollow urinary catheter of thin wall cylindrical shape, dispose a filled circles column jecket that can insert, take out, and the more hollow urinary catheter of filled circles column jecket is short.

The purpose of this utility model can also reach by following measure: offer two holes on the urinary catheter wall of hollow urinary catheter of thin wall cylindrical shape and solid elbow union end, and urinary catheter is provided with an air bag, and this airsac tube afterbody is connected with the airsac tube opening of a band piston.

Fig. 1 is an overcoat complete section front view of the present utility model.

Fig. 2 is filled circles column jecket figure of the present utility model.

This utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: 5 are solid elbow; the hollow urinary catheter 1 of thin wall cylindrical shape is connected into integral body with solid elbow 5; dispose one and can insert in the hollow urinary catheter 1 of thin wall cylindrical shape; the filled circles column jecket 8 of taking-up, and this filled circles column jecket 8 is than hollow urinary catheter 1 weak point of thin wall cylindrical shape; Offer two holes, 6,7 hollow urinary catheters 1 on urinary catheter 1 wall of hollow urinary catheter 1 and solid elbow 5 union ends and be provided with an air bag 2, these airsac tube 4 afterbodys are connected with the airsac tube opening 3 of a band piston.So just constitute the designed soft urinary catheter of this utility model.This utility model can be used following value: hollow urinary catheter 1 total length 370mm, external diameter 3mm to 6mm(different model), fore-end 5 long 75mm, middle part soft entirely (the hollow urinary catheter 1 of thin wall cylindrical shape) long 270mm, the long 25mm of afterbody, filled circles column jecket 8 long 300mm, anterior hollow urinary catheter part wall thickness 0.5 is to 1mm, hollow urinary catheter middle part wall thickness 0.1 is to 0.2mm, the same middle part of hollow urinary catheter afterbody internal diameter.This utility model operational approach is as follows: external orifice of urethra and surrounding skin routine disinfection, to in inserting thin wall cylindrical shape hollow pipe, the novel urinary catheter filled circles of disinfectant column jecket coat the sterilised liq paraffin wax, slowly insert urethra, proceed to about 3/4 from the air bag mouth of pipe 3 injection air or normal saline 5-20ml, by transfering to filled circles column jecket 4, as seen urine flows out in urinary catheter, connects urinal, end of operation.

The utility model has following advantage than existing urinary catheter:

Owing to adopt the tube wall of the soft softness of thin-walled, avoided stimulation and the damage of urinary catheter to mucous membrane of urethra, make the smoothly drainage of secretion of urethra, thereby also just avoided urinary tract infection, and can prolong significantly the time that keeps urinary catheter, it is more smooth to urinate simultaneously, forms regularly to urinate.

Claims (2)

1, a kind of soft urinary catheter, include a solid elbow, it is characterized in that having one to be connected into the whole hollow urinary catheter of thin wall cylindrical shape, in the hollow urinary catheter of thin wall cylindrical shape, dispose one and can insert with solid elbow, the filled circles column jecket that takes out, and the more hollow urinary catheter of filled circles column jecket is short.

2, soft urinary catheter according to claim 1, it is characterized in that on the urinary catheter wall of hollow urinary catheter of thin wall cylindrical shape and solid elbow union end, offering two holes, and urinary catheter is provided with an air bag, and this airsac tube afterbody is connected with the airsac tube opening of a band piston.
