Abstract
The utility model discloses a disposable urinary catheter. The utility model is characterized in that a flexible urinary catheter 1 is made of medical application transparent polyvinyl chloride plastics, and the middle part of the flexible urinary catheter 1 is provided with a hollow catheter 2. A one-way valve 3 is arranged in the hollow catheter 2, and the one-way valve 3 is a plastic product. The one-way valve 3 is in a shape of circular upper part, flat lower part and triangle side face, and the middle part of the flat site has small slots. The lower end is provided with a connecting element 4 which is used for connecting the flexible urinary catheter 1 and a urine collecting bag 5. After used one time, and the utility model can be destroyed, thus solving the cross infection of pathogenic bacteria caused by the halfway antisepsis of the existing rubber urinary catheter. The utility model has the advantages of low cost and convenient operation, and patients can not have the discomfortable feeling after clinical uses.
Description
This utility model relates to a kind of disposal urinary catheter.
In the prior art, catheter is that rubber is made, after repeatedly using, owing to thoroughly do not cause the pathogenic bacteria cross infection because of sterilizing.Chinese patent discloses a kind of " disposal urinary catheter ", the patent No. 89207250.4 its main features are that the urethral catheterization flexible pipe adopts medical transparent plastic manufacturing, insert a termination of urethra and make similar hemispherical cone, at a elliptical aperture apart from the relevant position of this termination, discharge in order to urine, this catheter advantage is promptly to disappear after the disposable effect to ruin, and shortcoming is not have anti-backflow device.
The purpose of this utility model mainly is the device that an anti-backflow is set in disposable urethral catheterization flexible pipe, refluxes from storing urine bag to solve urine.
The purpose of this utility model is to realize like this, a kind of disposable catheter that constitutes by plastic flexible pipe and intermediate connector, it is characterized in that: the catheter middle part is connected with hollow pipe, be provided with check valve in the hollow pipe, the urethral catheterization flexible pipe is connected by connector with storing urine bag is middle, and check valve adopts plastics to make, and check valve top is circular, the bottom is flat partially, and slit is arranged in the middle of the flat partially position.
This utility model advantage compared with prior art is in the middle of plastic catheter a hollow pipe to be set, and check valve is housed in hollow pipe, in case urine refluxes.But direct observation patient urethral catheterization situation from hollow pipe.
Fig. 1 is this utility model front view;
Fig. 2 is the check valve side view in this utility model.
Drawing is explained: urethral catheterization flexible pipe 1, hollow pipe 2, check valve 3, connector 4, storing urine bag 5, adhesive plaster 6.
The utility model will be further described below in conjunction with embodiment: urethral catheterization flexible pipe 1 is selected transparent medical polyvinyl plastics pipe for use, the hemispherical cone is made in its end (going into to urinate the hole), below cone, have the circular hole of 3 different sizes, discharge in order to urine.Be provided with the hollow pipe 2 of layer of transparent thin type at the middle part of urethral catheterization flexible pipe 1, in hollow pipe 2, be provided with check valve 3, check valve 3 tops have circular hole to be connected with urethral catheterization flexible pipe 1, by middle space 2 two sections urethral catheterization flexible pipes 1 are tightly connected again, urethral catheterization flexible pipe 1 bottom is provided with certain tapering, by connector 4 urethral catheterization flexible pipe 1 is connected with storing urine bag 5.Bottom, urethral catheterization flexible pipe 1 end (going into to urinate the hole) is fixed in the patient position by medical proof fabric 6, so that fixedly catheter 1 is stable.
