Embodiment 1

[0024] A collapsible dilatable urinary catheter, such as figure 2 As shown, it includes a urinary catheter 5, one end of the urinary catheter 5 is provided with a urinary joint 2, and one end of the urinary catheter 5 away from the urinary joint 2 is provided with a urination opening 51, and the end of the urinary catheter 5 near the urination opening 51 is outside The wall is connected with a drug injection tube 52 , and one end of the drug injection tube 52 is provided with a sealing plug 521 , and the sealing plug 521 is in interference fit with one port of the drug injection tube 52 .

[0025] In this embodiment, the urinary catheter 5 is supported by a rubber material with certain elasticity, and its material is soft, so that it will not cause damage to the urethra when inserted into the urethra.

[0026] like figure 1 and image 3 As shown, the surface of the catheter 5 is covered with a catheter outer tube 1, one end of the catheter outer tube 1 is tightly welded to ...

Embodiment 2

[0031] In the specific use process, the urinary catheter joint 2 is easy to block the urine inlet due to being close to the inner wall of the urethra during use, thereby affecting the catheterization effect. Therefore, we make improvements to the urinary catheter joint 2 on the basis of Example 1. , the urinary catheter connector 2 includes a urine inlet tube 21, one end of the urine inlet tube 21 is provided with a urine inlet head 22, the surface of the urine inlet head 22 is provided with a number of urine inlet ports 221, and the surface of the urine inlet tube 21 is provided with a number of side ports 211 A plurality of rubber protrusions 212 are provided on the surface of the urinary inlet tube 21 close to the outside of the side port 211 .

[0032] In this embodiment, the catheter joint 2 has a hemispherical hollow structure and is made of polyurethane foam material, and its structure is soft, which can prevent the patient from being injured when inserted into the ureth...

Abstract

The invention relates to the technical field of catheters, in particular to a retractable and expandable catheter. The retractable and expandable catheter comprises a catheter body, a catheterizing joint is arranged at one end of the catheter, and a urine draining port is formed in the end, away from the catheterizing joint, of the catheter; an outer catheter sleeves the surface of the catheter, an airbag ring sleeves the surface of the end, close to the catheterizing joint, of the outer catheter, and an elastic ring is arranged in the outer catheter; an inflating cavity is formed in the outerwall of the elastic ring and the inner wall of the outer catheter, a sleeving cavity is formed in the inner side of the elastic layer, and an inflating airbag is arranged at the end, away from the catheterizing joint, of the outer catheter, and the other end of the inflating airbag is connected with an air inlet tube. The catheter is simple in structure and convenient to use, the airbag ring andthe outer catheter can ensure that the outer wall of the catheter closely fits the urethra in the catheterizing process of the catheter to avoid that urine leaks, the outer catheter can expand and retract according to the need, therefore the size requirements of different patients can be conveniently met, the catheterizing joint can avoid that a catheterizing port is blocked, and therefore the catheterizing effect is improved.

Description

technical field [0001] The invention relates to the technical field of urinary catheters, in particular to a retractable and expandable urinary catheter. Background technique [0002] Urinary catheterization, commonly used for urinary retention, retain urine for bacterial culture, accurately record urine volume, understand the cause of oliguria or anuria, measure residual urine volume, bladder capacity and cystometry, inject contrast medium, bladder flushing, detect urethral abnormalities No stenosis and preoperative preparation of pelvic organs. [0003] However, due to bladder sphincter injury and relaxation, nerve dysfunction, and urethral spasm, the patient loses the ability to control urination, making urine flow out involuntarily, making the patient's perineum wet for a long time, which will lead to many complications, such as pressure sores, eczema, urinary tract Infection, etc., have greatly increased the workload of the nursing staff and the complications of the pa...
