Embodiment Construction

[0029] Such as figure 1 The shown urinary catheter comprises a catheter body 1 and a head sleeve 2, the head of the catheter body is provided with a urine inlet 3, and the tail is provided with an urination port 4, and the head sleeve 2 One end of the catheter is provided with a cutout 5 or an orifice 6, and the other end is open and provided with a limiting flange 7. The head sleeve 2 can be movably socketed outside the catheter body 1.

[0030] Further, the inner diameter of the head sleeve 2 is slightly larger than the outer diameter of the catheter body 1 .

[0031] Further, the limiting flange 7 is a crimp or a bell mouth.

[0032] The cutout 5 can be one or more. Each cut meets at the apex of the end where the cut is located, such as figure 2 The "一" incision, the "ten" incision, or the "ya" incision are shown. When all the cuts are stretched, the head of the catheter body can pass through the cuts.

[0033] The orifice 6 can be as image 3 Shown is circular, but ...

Abstract

The invention discloses a catheter, which comprises a catheter body. A urine inlet hole is formed on the head of the catheter body, and a urine drain hole is formed at the tail of the catheter body. The catheter is characterized by further comprising a head sleeve, wherein one end of the head sleeve is provided with notches or orifices, and the other end of the head sleeve is open and provided with a limiting flange; and the head sleeve can be movably sleeved outside the catheter body. The catheter provided by the invention can avoid bacteria on the inner side of a urethral orifice being brought into the deep part of the urethra and the bladder in a using process, and effectively reduces the occurrence of urinary tract infection of a patient.

Description

technical field [0001] The invention belongs to a clinical appliance, in particular to a urinary catheter. Background technique [0002] Studies have proved that patients with long-term indwelling urinary catheters are prone to urinary tract infections, and there are many reasons for urinary tract infections, but the most important point is that when the catheter is inserted, the bacteria on the inside of the urethral orifice are brought into the urinary tract by the catheter. Deep urethra and bladder, causing urinary tract infection and cystitis. [0003] In order to solve the problem of urinary tract infection in patients with long-term indwelling catheters, the following improvements to catheters have been made in the prior art: [0004] CN200820184424 discloses a urinary catheter, including a rubber tube, and a filter is fixedly arranged in the rubber tube. [0005] CN200920023324 discloses a balloon catheter with a guide core. A guide core made of steel wire is arrang...
