removed, it may damage the bladder and urethra.][CONTRAINDICATIONS・PROHIBITION]
・When using this product for the urethra, do not use it in cases with urethralstenosis.
[There is a risk of damage to tissues and urethral mucosa.]
・Do not perform an inspection by MRI (Magnetic Resonance Imaging) withthis product placement in the patient.
[Due to the influence of the high frequency electromagnetic field of MRI,
metal parts may cause local high frequency heating and cause burns to thepatient.][Shape, structure, principle]

・Catheter: Polyurethane
・Connector: Polypropylene
・Stylet: Stainless・Caulking pin: Stainless steel<Principles>・By inserting the catheter percutaneously into the urethra or bladder, urine isdischarged from the connector through the lumen through the tip hole / sidehole.

[Intended purpose, efficacy or effect]
・It is placed in the urethra or bladder and used for urinary catheterization.
[Operating or using method]
The below is a general procedure.
<Straight shape>[1] Disinfect the external urethral meatus and vulva.
[2] Remove the product from the packaging material hygienically and make sure thecatheter is no damaged.
[3] Apply a lubricant to the catheter as required and insert carefully into the urethra.
[4] Urine begins to flow out of the connector.
[5] Receive the outflow urine in the container.
[6] Place a catheter based on the in-hospital medical care protocol.
[7] When removing the catheter, pull out carefully.
<Pigtail shape>[1] Disinfect the external urethral meatus and vulva.
[2] Remove the product from the packaging material hygienically and make surethe catheter is no damaged.
[3] Insert the stylet into the catheter and extend the pigtail shape.
[If the stylet is tight at the loop, do not force and stretch the loop lightly withyour fingers.][4] Apply a lubricant to the catheter as required and insert carefully into the urethra.
[5] Insert the catheter and when it crosses the extraurethral sphincter, pull out thestylet for about one finger (about 2 cm) and insert the catheter and stylet
together.
(At this time, the tip pigtail catheter is J shape.)[6] If it felt resistance to contact the bladder wall, etc., or insert it about 3 cm, pullout the remaining stylet.
[Do not pull immediately after placement because the loop part is formedslowly.][7] Urine begins to flow out of the connector.
[8] Receive the outflow urine in the container.
[9] Place a catheter based on the in-hospital medical care protocol.
[10] When removing the catheter, pull out carefully. If it felt abnormal resistance,
return the catheter to the bladder and pull out lightly. The push-pull operationof the catheter is repeated several times to release the resistance, and thecatheter removal operation is restarted.
<Precautions for the using method>[1] Make sure to visually inspect the appearance of this product before use.
[2] Use immediately after opening the package.
[3] For the pigtail shape, insert the preset stylet to the back just before use andstraighten the shape part.
[If the inserted stylet is left for a long time, it may be difficult for the shape toreturn and to place.][4] When replacing the catheter, prepare everything so that it can be replaced
without delay before removing the catheter.
[Reinsertion becomes difficult over time after catheter removal.][5] When fixing the catheter to the skin, do not fix the catheter directly with asuture thread.
[There is a risk of blockage or rupture.][6] Always pay attention to the fixed state of the catheter when placing thecatheter.
[Twisting and bending can occlude the catheter.][7] When placing a catheter, after confirming the outflow of urine, insert for a
sufficient length before placement. If urine outflow cannot be confirmed,
inject an appropriate amount of sterile saline from the connector at thediscretion of the veterinarian, confirm that the sterile saline is discharged as

[Precautions]<Important basic caution>[1] Since the catheter lumen may be blocked by urine components and stones etc.,
make sure to manage the catheter.
[2] Check the drainage status regularly during catheter placement.
[3] Manage appropriately the catheter state during placement. If necessary, checkthe placement state of the catheter by fluoroscopy.
