Description
Technical field
The present invention relates to men's external catheter, more particularly to a kind of men's external catheter and preparation method thereof.
Background technology
Men's external catheter (hereinafter referred to as MEC), also referred to as sheath MEC, aim at male and handle urinary incontinence design.
One type MEC near-end is the sheath of a thin tubular structure as sheath, is worn to the penis of male patient
On.Its distal end seems thicker one tubule of band or the simply funnel structure of a straight tube, it may be connected to a urine
Bag.The MEC of another species is referred to as Texas MEC, and its distal end is straight tube made of a plastics or rubber, without funnel
Structure.Sheath is longer than common MEC's, and is connected to straight tube with a plastic inserts by machine.In order to prevent MEC from penis
On come off and prevent wear use during leakage of urine occurs, patient can tie up MEC sheath on penis using a belt,
Or adhered to using the MEC with self-adhesive inside sheath on penis.
It is different from being designed to the self retaining catheter that the long period persistently uses, for health in terms of consideration generally build
View changes MEC daily.The major advantage that MEC surmounts self retaining catheter is, MEC need not insert the small opening of penis to wing
Guang drainage of urine.It is well known that conduit insertion penis can cause some uncomfortable, it is also possible to cause male patient's urinary tract infections.And
And wearing MEC and leg urinal also will not be obvious.Therefore, MEC just becoming in the male patient for have incontinence problems increasingly by
Welcome, especially those younger patients, their activities are more and can change MEC daily.
Except incontinent patients, MEC, such as truck driver or taxi driver is also commonly used in healthy male, and they can not stop
Car goes to toilet and needs to stay the long period in truck or automobile., can more more options Texas for these users
MEC rather than common MEC.
At present, or all MEC are made up of natural latex rubber, or the more expensive silicone gum rubber system without latex
Into.Due to latex allergy, silica gel MEC is used in more patients.However, also had disadvantages that using MEC made of silica gel.
Compared with natural emulsion MEC, silica gel MEC sheath is thicker and compactness is smaller.Silica gel sheath is tied up in penis with belt
On allow it to prevent that leakage of urine is relatively difficult because too thick silica gel sheath is not easy to fit with the profile of penis.It is moreover, thicker
Silica gel sheath usually require to be adhered on penis using seccotine.Although viscose glue can allow patient to be easier when wearing sheath
It is sealed to around penis, it is but very time-consuming and some pain or skin may be brought to pierce to patient that this MEC is removed after use
Swash.In addition, silica gel is not a kind of good heat conductor, some patients can be caused to perspire and uncomfortable.
Except it is above-mentioned the shortcomings that, it is noted that using silica gel make MEC need to use liquid injection molding to be molded.Not only use
Very expensive in the stainless steel mould of liquid injection molding shaping, it is also very inflexible, cannot be repaiied again because mould is once carried out
Change.High mould input cost and mould do not have flexibility, making it difficult to trendy silica gel MEC products are manufactured, and initial
It is difficult to carry out sustained improvement to silica gel MEC after design.In addition, silica gel cannot be used for manufacturing " Texas MEC ", because this
MEC needs thinner and longer sheath.
