Description

Urinary catheter with plastic bracket and disinfection device for the bracket

technical field

The invention relates to the field of medical instruments, in particular to a catheter with a plastic bracket and a disinfection device for the bracket.

Background technique

Urinary catheterization is one of the most common clinical treatments. It refers to inserting a urinary catheter into the bladder through the urethra to draw out the urine in the bladder. Most of the catheters commonly used in clinical practice are made of rubber or silicone. .

With the aging of the society, the population of elderly men is increasing. Prostatic hyperplasia is a common disease of elderly men. Prostatic hyperplasia will cause the patient's bladder neck to rise, the posterior urethra to be narrowed, and the urethra to become longer, narrower and curved. , the clinical manifestations are voluntary urination difficulty, and even acute urinary retention, that is, a large amount of urine accumulated in the bladder that cannot be eliminated. Acute urinary retention will cause severe discomfort and functional impairment of the upper urinary tract.

Clinically, an indwelling catheter is usually used to drain the urine in the patient's bladder to treat acute urinary retention, but because the patient's urethra becomes longer, narrower and bent, the catheter itself is flexible and flexible when inserted It is difficult to enter the bladder through the deformed urethra, and friction between the catheter and the deformed urethra during insertion increases the risk of urethral mucosal injury.

Aiming at the problem that the catheter is difficult to insert, at present, hard metal brackets are mainly placed in the catheter to increase the hardness of the catheter, thereby facilitating the insertion of the catheter. However, in clinical practice, with a hard metal bracket The shape of the urinary catheter is fixed and cannot be bent according to the shape of the urethra. When the catheter is inserted, it is easy to cause urethral mucosal damage, urethral false tract formation, and even prostate injury and bleeding. After these symptoms appear, it is difficult to use the catheter again. Urine is derived, and only suprapubic cystostomy can be performed on the patient for urine drainage, which increases the pain and financial burden of the patient, and also prolongs the hospital stay. At the same time, urethral mucosal injury and formation of urethral false tract will significantly increase the incidence of long-term urethral stricture in patients, and further treatment is required.

Detailed ways

Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

Referring to Fig. 1, an embodiment of the present invention provides a urinary catheter with a plastic bracket, including a tube body 1 and a plastic bracket 2, the plastic bracket 2 can be inserted into the inside of the tube body 1, and the tube body 1 can be inserted into the tube body 1 according to the plastic bracket 2 The shape of the tube body 1 is bent, and one end of the tube body 1 is the catheter connection port 3. The tube body 1 is also provided with an interconnected air bag and a catheter air bag channel 11. The air bag is located on the tube body 1 away from the catheter connection port 3. One end of the urinary catheter balloon channel 11 is set adjacent to the catheter connection port 3, the catheter balloon channel 11 is used to pass liquid into the balloon to inflate the balloon. When in use, the balloon enters the bladder of the patient along with the tube body 1 After the balloon is filled with water and expanded, the tube body 1 can be prevented from protruding from the bladder.

The plastic support 2 includes a deformation shell 4, a metal fixing wire 5, an adjustment handle 6 and a handle 8. One end of the metal fixing wire 5 passes through the deformation housing 4 and is fixed at its end, and the other end is connected with the adjustment handle 6. When the deformation housing 4 When inserted into the tube body 1, the handle 8 is located outside the tube body 1.

A fixed soft plug 7 is arranged between the catheter connection port 3 and the deformable shell 4. Before the deformable shell 4 is inserted into the tube body 1, the fixed soft plug 7 is first sleeved on the deformable shell 4, and the end of the deformable shell 4 After passing through the deformable shell 4, it is inserted into the tube body 1, and the fixed plug 7 is held against the catheter connection port 3. The fixed plug 7 is in the process of extrusion of the catheter connection port 3, and the inner diameter of the inner channel decreases. To be close to the outside of the deformable shell 4, prevent the plastic bracket 2 from sliding up and down when the catheter is inserted into the patient's body, and at the same time, fix the soft plug 7 to seal the catheter connection port 3, effectively preventing the urinary catheter from entering the bladder. The gush wets the patient's bed linen.

The deformable shell 4 includes a number of interlaced cylinders 9 and elliptical spheres 10, the cylindrical cylinder 9 and the elliptical sphere 10 all have passages for the metal fixing wire 5 to pass through, and the end of the cylindrical cylinder 9 connected with the elliptical sphere 10 A groove is provided, and the end of the elliptical sphere 10 that is in contact with the groove can be snapped into the groove to form a fitting structure, and the elliptical sphere 10 can be rotated to change the angle and direction, that is, the bending direction and curvature of the deformation shell 4 It can be adjusted manually according to the actual situation. After adjusting to the desired shape, tighten the metal fixing wire 5 through the adjustment handle 6 to fix the shape of the deformation shell 4. When the deformation shell 4 is inserted into the tube body 1, the adjustment handle 6 is located in the tube body 1 outside.

In addition, the metal fixing wire 5 can be loosened by adjusting the handle 6, so that the metal fixing wire 5 is in a relatively movable state, retaining the variability of the catheter body 1 while increasing the hardness of the catheter body 1, avoiding the After the metal fixing wire 5 is inserted into the tube body 1 alone, the hardness of the overall structure is too large, resulting in damage to the urethral mucosa and formation of a false tract during use.

Referring to shown in Fig. 2, the present invention also provides a kind of disinfection device that is used for plastic support, comprises flexible container 12, and one end of flexible container 12 is closed end 13, and the other end is open end 14, and among the present invention, flexible container 12 is Bellows closed at one end.

The plastic support 2 can be inserted into the flexible container 12 from the open end 14, the open end 14 is provided with an end cap 17, the flexible container 12 is provided with a connecting position 15 near the open end 14, and the closed end 13 is provided with a clip 16. When the container 12 is bent, the clip 16 can be connected with the connecting position 15, which reduces the space occupied by the flexible container 12 and is convenient for carrying and storage.

In this embodiment, both the end cap 17 and the clamping member 16 are connected to the flexible container through a freely rotatable fixing belt.

After each use of the plastic support 2, rinse it with clean water, then put it into a disinfection device with disinfectant, and take it out of the disinfection device for use next time, so as to avoid the plastic support 2 from being infected by bacteria during storage , causing bacteria to be brought into the bladder to cause infection during use, which can improve the safety of use.
