Description
Technical field
The present invention relates to men's external catheter, particularly men's external catheter of one and preparation method thereof.
Background technology
Men's external catheter (hereinafter referred to as MEC), is also referred to as condom MEC, aims at the male sex and processes urinary incontinence design.Wherein the near-end of a class MEC is the sheath of a thin tubular structure as condom, is worn on the penis of male patient.Its far-end similarly is the funnel structure of a thicker band tubule or a just straight tube, can be connected to a urinal.The MEC of another kind is called as Texas MEC, and its far-end is the straight tube that plastics or rubber are made, and does not have the structure of funnel.Sheath than the length of common MEC, and is connected to straight tube by a machine plastic inserts.Come off to prevent MEC from penis and prevent from wearing in use procedure and leakage of urine occurs, patient can use a belt that the sheath of MEC is tied up on penis, or uses the MEC with self-adhesive inside sheath to adhere on penis.
Different from being designed to the self retaining catheter that the long period continues to use, the consideration for health aspect advises that every day changes MEC usually.The major advantage that MEC surmounts self retaining catheter is, MEC does not need the little opening inserting penis to bladder drainage urine.As everyone knows, conduit inserts penis and some can be caused uncomfortable, also may cause male patient's urinary tract infections.Further, MEC is worn and leg urinal also can not be obvious.Therefore, MEC is just becoming more and more welcome in the male patient having incontinence problems, especially those younger patients, and their activity is more and can change MEC every day.
Except incontinent patients, healthy male also often uses MEC, such as truck driver or taxi driver, and they can not stop toilet and need the slow-witted long period in truck or automobile.For these users, meeting more more options Texas MEC instead of common MEC.
At present, all MEC or be made up of natural latex rubber, or not the making containing the silicone gum rubber of latex of more expensive.Due to latex allergy, more patient is using silica gel MEC.But the MEC using silica gel to make also has a lot of shortcoming.Compared with natural emulsion MEC, the sheath of silica gel MEC is thicker and degree of laminating is less.With belt silica gel sheath tied up allows it prevent leakage of urine more difficult, because too thick silica gel sheath is not easy to fit with the profile of penis on penis.And thicker silica gel sheath needs to use seccotine to be adhered on penis usually.Although viscose glue is more easily sealed to around penis sheath when patient can be allowed to wear, removed this MEC very consuming time and may be with to patient and serve pain or skin irritation. after useIn addition, silica gel is not a kind of good thermal conductor, can cause perspiring and discomfort to some patients.
Except above-mentioned shortcoming, it should be noted, adopting silica gel to make MEC needs to use liquid injection molding shaping.Not only very expensive for the stainless steel mould that liquid injection molding is shaping, it is also very dumb, because mould just can not be revised once carry out again.High mould input cost and mould do not have a handiness, make to be difficult to manufacture trendy silica gel MEC product, and be difficult to carry out Continual Improvement to silica gel MEC after initial designs.In addition, silica gel can not for the manufacture of " Texas MEC ", because this MEC needs thinner and longer sheath.
