Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and in particular relates to a disposable fistula fluid drainage tube. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine.

[0003] Current catheters generally adopt a round balloon design and the balloon is far away from the front end of the catheter, making the front end of the catheter more prominent. When a patient uses the catheter, the spherical balloon on the catheter in the patient's bladder has a larger area after water injection, so that the spherical balloon contacts the patient's bladder with a larger area, and the sharp part of the front end of the catheter will damage and irritate the mucosa in the bladder, thereby further irritating the bladder and causing discomfort to the patient.

[0004] After the current urinary catheter is placed in the desired treatment position, urine may flow out. The residual urine in the bladder needs to be frequently wiped, which can easily cause damage to the patient's vaginal opening and redness, swelling and discoloration of the skin around the anus in patients with ovarian cancer surgery, vesico-vaginal fistula and rectovaginal fistula. Therefore, the present device provides a disposable fistula fluid drainage tube. Utility Model Content

[0005] The purpose of the utility model is to provide a disposable fistula fluid drainage tube to solve the above-mentioned technical problems in view of the deficiencies of the prior art.

[0006] The utility model embodiment adopts the following technical scheme: it includes a three-chamber drainage catheter for urine drainage of patients with vaginal fistula and bladder diseases, the three-chamber drainage catheter is provided with an air bag for expansion by water injection or inflation after being inserted into the bladder to play a limiting role, the air bag is in the shape of a cup with a wide top and a narrow bottom and is integrally formed with the three-chamber drainage catheter, the three-chamber drainage catheter is provided with a urine drainage hole at the head end and four drainage holes are arranged symmetrically in pairs below the drainage hole, two drainage grooves are symmetrically arranged on the outside of the air bag, and the three-chamber drainage catheter is provided with an introduction hole at the corresponding position of the lower end of the two drainage grooves,

[0007] After the three-lumen drainage catheter is placed in the desired patient treatment position, the device can facilitate the discharge of urine from the patient and avoid the outflow of residual urine in the bladder, which requires frequent wiping of the genitals, which can easily cause damage to the patient's vaginal opening and redness, swelling and discoloration of the skin around the anus in patients after ovarian cancer surgery, vesicovaginal fistula and rectovaginal fistula. It effectively improves the patient's discomfort symptoms and reduces the occurrence of urinary tract infection. At the same time, the airbag is in the shape of a cup that is wide at the top and narrow at the bottom, which can effectively reduce the contact area between the airbag and the bladder, reduce urinary tract irritation symptoms, and relieve the patient's discomfort symptoms.

[0008] Furthermore, the airbag is located close to the front end of the three-chamber drainage catheter, and after being filled with water or inflated, the upper end of the airbag is butterfly-shaped and the lower end is conical.

[0009] Furthermore, the butterfly-shaped position at the upper end of the airbag and the front end of the three-chamber drainage catheter form a groove, and the groove is just wrapped around the outside of the plurality of drainage holes.

[0010] Furthermore, the three-lumen drainage catheter is provided with a water injection port, a flushing and drug injection port and a liquid outlet, the water injection port is provided with a water injection valve, and the liquid outlet on the three-lumen drainage catheter is provided with a pollution-proof cap.

[0011] Furthermore, the four drainage holes and the two introduction holes on the three-lumen drainage catheter are arranged at different angles.

[0012] Furthermore, the three-lumen drainage catheter and the airbag are both made of antiseptic materials.

[0013] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0014] After the patient is implanted with the device, the upper end of the airbag is butterfly-shaped after water injection or inflation, and the lower end is conical. The expansion plays a limiting role, and the butterfly position at the upper end of the airbag forms a groove with the front end of the three-chamber drainage catheter, and the groove is just wrapped around the outside of several drainage holes. The main urine will be discharged into the three-chamber drainage catheter through the drainage holes on the three-chamber drainage catheter, and some urine will flow out along the side wall of the bladder. At this time, two drainage grooves are symmetrically arranged on the outside of the airbag, and the conical setting of the lower end can facilitate the inflow of urine, and finally flow into the three-chamber drainage catheter through the flow introduction hole, and the inside of the bladder When there is a lot of urine, it will not be discharged in time through the catheter hole, causing bladder obstruction and urine flowing out from the side wall. Therefore, a groove can be formed through several drainage holes through the butterfly position at the upper end of the airbag and the front end of the three-lumen drainage catheter to introduce urine into the several drainage holes and flow into the three-lumen drainage catheter, and finally discharged through the liquid outlet, avoiding the residual urine in the bladder from flowing out, the need to frequently wipe the genitals, and the damage to the vaginal opening and redness, swelling and discoloration of the skin around the anus in patients with ovarian cancer surgery, vesicovaginal fistula and rectovaginal fistula, effectively improving the patient's discomfort symptoms and reducing the occurrence of urinary tract infections.
