Description

Double-bag external urethral sphincter dilating tube

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to external sphincter of two sacs urethra expands pipe.

Background

Neurogenic bladder is a functional disorder of urinary bladder and urethra caused by damage to central or peripheral nerves that control the function of urination, and common symptoms are urinary retention, urinary incontinence and mixed urination disorders, with spinal cord injury being the most common cause. Clinically, the emphasis of neurogenic bladder therapy for spinal cord injury patients is to restore the micturition reflex and micturition control function of the patients through various functional exercises. In clinical practice, the external sphincter of urethra is expanded by adopting the traditional catheter balloon, and the patient is instructed to perform active urination so as to achieve the purpose of feedback urination. Can effectively improve the urination control function of the patient and is beneficial to recovering the urination reflex of the patient.

In practice, it has been found that when the above-mentioned rehabilitation training is carried out using a conventional catheter, the following drawbacks exist:

first, the balloon of the existing catheter is located at the end of the catheter body, and is generally used for fixing the catheter. When the balloon is used for expansion, the balloon needs to be moved to the position of the external urethral sphincter, and the balloon completes the expansion once passing through the external urethral sphincter. After one expansion, the catheter is then reinserted back to the initial position for the next expansion. Repeated reinsertion of the catheter and removal of the balloon increases the risk of urethral trauma and urinary system infection.

Secondly, the saccule of the prior catheter is spherical, the section of the external sphincter of the urethra is approximately in an omega shape, and the saccule has larger shape difference, so that the saccule can not have good expansion effect during expansion, and the pressure of urine passing through the external sphincter of the urethra can not be well simulated during normal urination.

Thirdly, the existing catheter can not detect the pressure in the saccule, and the research and observation of the pressure change of the urethra during urination are very important for the recovery training.

Fourthly, the existing catheter has no scale marks, and after the balloon reaches the position of the external sphincter of the urethra, the balloon needs to be temporarily marked and positioned by an oil pen holder, so that the aseptic principle is easily violated. And the marker of the oil pen is easy to be desalted or erased by disinfectant, and the correct insertion depth of the catheter is difficult to judge when the catheter is reinserted into the catheter for next expansion.

In conclusion, the external urethral sphincter is expanded to effectively help the patient to recover the micturition reflex, and the treatment of the neurogenic bladder is good. However, there is no specific dilating tube for external sphincter of urethra in the prior art, and there are many defects in using a catheter for dilation, so it is necessary to design a dilating tube suitable for external sphincter of urethra.

Four cavities which are mutually isolated are arranged in the tube body 1, namely a drainage cavity 12, a fixed sacculus communicating cavity 14, an expansion sacculus communicating cavity 13 and a pressure measuring cavity 15. Each cavity extends along the length direction of the tube body 1, but the extending lengths of the cavities are different according to the functions required to be realized. In order to realize the mutual isolation of the cavities, as shown in fig. 2, a drainage cavity 12 is arranged in the middle of the cross section of the tube body 1. The pressure measuring cavity 15 and the expansion balloon communicating cavity 13 are respectively positioned at two sides of the drainage cavity 12, and the fixed balloon communicating cavity 14 is positioned at the upper part of the drainage cavity 12, so that the cavities in the tube body 1 are mutually isolated. The above is only an embodiment of illustrating the arrangement position of each cavity, and the position of each cavity is not limited to be arranged in the above manner, and the positions of each cavity in the tube body 1 can be changed, as long as the cavities can be isolated from each other and the functions of each cavity can be realized.

The drainage cavity 12 extends from the beginning of the tube body 1 to the position of the drainage liquid inlet 111. The drainage liquid inlet 111 is communicated with the drainage cavity 12, and the other end of the drainage cavity 12 is used for communicating a drainage device, such as a negative pressure drainage bottle or other negative pressure drainage devices. Through the negative pressure, the urine flows into the drainage cavity 12 through the drainage liquid inlet 111, then flows through the drainage cavity 12, and flows into the drainage device. The above is the process of urine drainage.

A fixed ball bag 2 is arranged at the position of the tube body 1 close to the tail end, the fixed ball bag 2 is spherical under the opening state, and the fixed ball bag 2 is made of soft rubber.
