Urinary catheter insertion alignment device for a female patient, method for making same, and method for using same
View Patent ↗A urinary catheter insertion alignment device for use by a female patient is disclosed. The urinary catheter insertion alignment device is molded to the patient's vaginal anatomy using impression material while an intermittent urinary catheter is inserted into the urethral orifice. Once the urinary catheter insertion alignment device has hardened, the intermittent urinary catheter is removed therefrom. Thereafter, the urinary catheter insertion alignment device may be fitted to the vaginal anatomy by the patient, which positions the passageway therethrough (formerly occupied by the urinary catheter in place during the molding operation) directly over the urethral orifice. The patient may then easily insert an intermittent urinary catheter (of a size smaller than that used during the molding operation) through the passageway, into the urethral orifice, and into the bladder for drainage of the bladder.
1. A method of forming a urinary catheter insertion alignment device for a female patient, the method comprising the steps of:
a. spreading the labia majora and labia minora of the patient to expose a urethral orifice of the patient;
b. inserting an intermittent urinary catheter into the urethral orifice of the patient;
c. applying impression material to an area surrounding the catheterized urethral orifice;
d. allowing the impression material to harden;
e. removing the hardened impression material and the urinary catheter from the patient; and
f. removing the urinary catheter from the hardened impression material to form the urinary catheter insertion alignment device.
2. The method of claim 1 , wherein at least steps (a)-(e) are performed within a sterile field.
3. The method of claim 1 , wherein step (a) further comprises placing a finger of an operator to the left and to the right of the urethral orifice at the vestibular level and spreading the labia majora and labia minora until the external urethral orifice is exposed and standing alone.
4. The method of claim 1 , wherein step (a) further comprises spreading the labia majora and labia minora using a retractor instrument.
5. The method of claim 1 , further comprising the step of: after step (a) and before step (b), cleansing the peri-urethral mucosa of the patient with a cleansing solution.
6. The method of claim 1 , wherein the intermittent urinary catheter comprises a 16 Fr/Ch (5.3 mm) intermittent urinary catheter.
7. The method of claim 1 , wherein step (b) comprises inserting the intermittent urinary catheter into the urethral orifice of the patient to a depth of approximately 20 mm.
8. The method of claim 1 , further comprising the step of: after step (b) and before step (c), applying a quantity of sterile lubricant to an area surrounding the catheterized urinary orifice and onto approximately the first 40 mm of the intermittent urinary catheter protruding from the urinary orifice.
9. The method of claim 1 , wherein step (c) further comprises applying the impression material to the area surrounding the catheterized urethral orifice approximately 30 mm on either side of the urethral orifice and to a depth of approximately 20 mm.
10. The method of claim 1 , wherein step (c) further comprises applying the impression material to the area surrounding the catheterized urethral orifice and down the length of the vagina and the perineum, but not to include the anus.
11. The method of claim 1 , wherein the impression material comprises super hydrophilic vinyl polysiloxane.
12. The method of claim 1 , further comprising the step of: after step (c) and before step (d), molding a desired surface contour onto an exterior surface of the impression material.
13. The method of claim 1 , further comprising the step of: prior to step (c), positioning a concave mold around the catheterized urethral orifice, wherein step (c) comprises injecting the impression material into an interior of the mold.
14. A method for using a urinary catheter insertion alignment device for insertion of an intermittent urinary catheter into the urethral orifice of a female patient, the method comprising the steps of:
a. spreading the labia majora and labia minora of the patient to expose a urethral orifice of the patient;
b. placing a urinary catheter insertion alignment device, which is shaped to conform to the patient's vaginal anatomy, over the urethral orifice, thereby aligning a passageway formed through the urinary catheter insertion alignment device is positioned over the urethral orifice; and
c. inserting an intermittent urinary catheter through the passageway and into the aligned urethral orifice until a distal end of the intermittent urinary catheter is positioned inside the patient's bladder.
15. The method of claim 14 , further comprising the step of:
d. draining the bladder through the intermittent urinary catheter.
16. The method of claim 15 , further comprising the steps of:
e. removing the intermittent urinary catheter from the bladder and from the passageway of the urinary catheter insertion alignment device; and
f. removing the urinary catheter insertion alignment device from the patient.
17. The method of claim 1 , wherein step (a) further comprises placing a finger of the patient to the left and to the right of the urethral orifice at the vestibular level and spreading the labia majora and labia minora until the external urethral orifice is exposed and standing alone.
18. The method of claim 14 , wherein the intermittent urinary catheter comprises a 14 Fr/Ch (4.7 mm) intermittent urinary catheter and the passageway comprises a 16 Fr/Ch (5.3 mm) diameter.
19. A urinary catheter insertion alignment device formed by the process of claim 1 .
