Background technique

Hematuria is a common disease in urology, often caused by urinary tract infection, stones, kidney cancer, bladder cancer and prostate cancer. Sometimes a large amount of hematuria can form a blood clot in the bladder, especially in patients with advanced cancer, the larger blood clot will fill the bladder, which will cause difficulty in urinating, or even the inability to urinate, and in severe cases, the bladder may rupture , seriously threatening the life and health of patients. In order to prevent the patient from filling the bladder with blood clots and ensure that the patient can urinate unobstructed, in clinical work, the most common treatment method is to give the patient a urinary catheter catheterization, and to keep the catheterization. Continuous three-way bladder irrigation is the most commonly used treatment method. Because the commonly used three-way catheter such as patent CN99252651.5 has a small lumen and a closed head end, when the patient continues to bleed, blood clots are formed, which often block the catheter, so that clinicians have to wash the catheter frequently In order to wash out the blood clot, sometimes when the blood clot is large, cystoscope washing has to be used.

Detailed ways

A specific embodiment of a bladder irrigation catheter of the present invention is given below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

Example 1:

As shown in Figure 1-2, a bladder irrigation catheter includes a catheter body 1, an inner sheath 3, a syringe connector 4, a bladder irrigation connector 5, an air bag interface 6, and an air bag 7, away from the catheter body An annular airbag 7 is fixed on the outside of the urine collection bag interface 2 side of 1, the inner tube 8 is attached to the main body of the catheter, and the airbag interface 6 communicates with the airbag 7 through the inner tube 8; one end of the inner sheath 3 is connected to the syringe connector 4, and the other end The end of the catheter is narrowed in an arc shape, and a flushing hole is left in the center. The upper part of the catheter body 1 is connected to the bladder flushing joint 5. When the inner sheath 3 is relatively inserted into the catheter body 1, it fits between the catheter body 1 and The bladder flushing joint is blocked, and when the inner sheath is relatively pulled out of the catheter body 1, the catheter body 1 is connected to the urine collection bag for collecting urine.

The length of the urinary catheter is 40cm-45cm; the main material of the catheter is natural latex, and the inner sheath is hard plastic; The length of the interface 6 and the bladder flushing joint 5 is 5-6 cm. The bladder flushing joint 5 is connected to the catheter at a distance of 5 cm from the upper end of the catheter body, and the balloon interface 6 passes through the catheter at a distance of 5 cm from the upper end of the catheter body. , the urine collection bag interface 2 can be inserted into the inner sheath 3, the airbag interface 6 and the lower end airbag 7 are connected through the inner tube 8; the length of the inner sheath is 40-45cm, the upper end of the inner sheath is provided with a syringe connector 4, and the syringe connector 4 includes Syringe tube 9, and nipple sleeve 10 integrally formed with syringe tube 9, one end of nipple sleeve 10 is folded outwards to connect with the top of syringe tube 9, and the needle tube from the top of syringe tube 9 along the axial direction 9 The diameter is reduced, the bottom end of the syringe tube 9 is connected to the inner sheath 3, and the nipple sleeve 10 is used for inserting the nipple needle tube of the syringe; a flushing hole 12 is left at the lower end of the inner sheath, and an arc is used between the flushing hole 12 and the lower end of the inner sheath 3 The transition pipe 13 is connected, and the diameter of the flushing hole is 0.5 cm; the model of the nipple sleeve 10 is F24, and the diameter is 0.8 cm.
