Description
Technical field
This utility model belongs to medical device technical field, more particularly to a kind of multi-cavity urethral catheter, more particularly to a kind of three
Chamber, four chambers or five chamber catheters.
Background technology
Catheter, is, with natural rubber, silicone rubber or pipeline made by polrvinyl chloride (PVC), can to insert via urethra
Bladder out, after catheter insertion bladder, has an air bag to stay fixed catheter so as to drainage of urine near catheter head end
In intravesical, and abjection is difficult, and drainage tube connection urinal collects urine.Catheter model, according to the girth point 6F- of external diameter
30F totally 13 specifications and models, conventional adult's catheter has tetra- kinds of models of 12F, 14F, 16F and 18F.
Catheter type includes：Ordinary urethral catheter：For disposable non-indwelling urethral catheterization；Bacterium shape catheter：For pubis
Upper bladder stoma and Ceostomy；Tip catheter：For prostate hyperplasia；Metal urethral catheter：It is common for meatal stenosiss
Urethral catheterization fails；Foley catheter：Common clinic is commonly used.Air sac urinary catheter is divided into two kinds of single-chamber catheter and multi-cavity urethral catheter.It is single
Chamber catheter is made up of conduit, excretion cone-shaped interface, valve plug；Multi-cavity urethral catheter by conduit, excretion cone-shaped interface, valve plug,
Qi of chong channel ascending adversely cone-shaped interface, spherical envelope composition.It is divided into two kinds of adult's use (F14-F24) and children's use (F8-F12) by applicable object；
Adult uses and is divided to again men's and lady's two kinds (F12 is gynecological's jet water spout).
For Foley catheter：Before intubation, suitable catheter should be selected according to the situation of patient, and check the matter of conduit
Whether amount, air bag are excellent etc..See in cathing process after having urine to flow out, reinject air bag tube chamber liquid, speed should be delayed
Slowly.The amount of injection should be accurate, and blend compounds cloth writes on the amount injected above, is affixed on the initiating terminal of air bag tube chamber.Air bag has been noted
After liquid, catheter is slowly pulled outward, after moving certain position to and having resistance, provable air bag has pressed close to wall of urinary bladder；Such as
Drawing is subject to resistance, should check the depth of catheter, because of the balloon segment for having 2-3cm at air sac urinary catheter tip inlets, such as puts pipe range
Degree is inadequate, and air bag is located at Posterior urethral not completely into bladder, and air bag can cause certain damage to Posterior urethral mucosa.When pulling out
Guan Shi, the amount for extracting liquid in air bag out is equal with the amount of institute labelling, in case liquid is not exhausted in air bag, and tube drawing by force, draw
Play the damage of urethra.
To the disposal of long term indwelling catheter person because urinary catheter fixes improper, pulled by gravity sagging；Carrying out urethra simultaneously
During nursing, conduit is too pulled outward, makes air bag be close to wall of urinary bladder；Or because patient is irritated, frequently change position, make urinary urine bladder
Mucous membrane receives mechanical friction with catheter contact site；Simultaneously because at air bag urinate mineralization make catheter be etched degeneration,
Elasticity is deteriorated；Above-mentioned situation can cause the adhesion of tube chamber and pressurized obstruction, may cause air bag hole plug, and then cause air bag
In liquid cannot be completely exhausted out.In tube drawing in the case that the liquid discharge in air bag is insufficient, urethral mucosa can be caused
Damage, and produce difficulty in decannulation.
