Description
Technical field
The invention belongs to clinical treatment urethral catheterization technical fields, and in particular to a kind of silicone catheter development RTV liquid end socket
Glue, the invention further relates to a kind of preparation methods of silicone catheter development RTV liquid end socket glue.
Background technique
Medically, catheter is per urethram inserted into bladder, drains urine.Urethral catheterization be divided into catheter retaining urethral catheterization and
Two kinds of the urethral catheterization of having a rest property.The former catheter is retained in always in patient body, just pulls out or regularly replace new pipe in state of an illness license.
The latter is then primary every urethral catheterization in 4-6 hours, extracts catheter after bladder emptying.Indwelling catheter operating procedure is by urethral catheterization
Pipe is inserted into appropriate depth (women 2-4cm, male 20-22cm), after seeing urine outflow, is inserted into 1-2cm.Then urethral catheterization is fixed
Pipe, connects drainage bag.It removes barriers situation for urine such as the retention of urine, the retention of urines.It is worth noting that, catheter should not repeat to make
With otherwise user is possible to by bacterium infection.But conventionally fabricated catheter durability degree is not high, along with use when
Between it is general longer, and need to import patient's body, it is therefore desirable to the catheter more renewed in time not only increases medical treatment cost,
And it is time-consuming and laborious.
Therefore it is directed to this status, there is an urgent need to design and produce a kind of silicone catheter development RTV liquid end socket glue, with
Meet the needs of actual use.
