Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and more specifically, to an expandable device. Background Technology
[0002] Urinary incontinence refers to the involuntary leakage of urine through the urethra. When it occurs secondary to coughing, sneezing, laughing, getting up, brisk walking, running, jumping, or other situations that increase abdominal pressure, it is called stress urinary incontinence. Urinary incontinence is a fairly common problem, especially among the elderly. It can have a serious negative impact on a patient's quality of life, psychological well-being, and social life.
[0003] A sphincter is a ring-shaped muscle located in the walls of certain lumens in the human and animal body. Sphincters are normally in a draining state, thus closing the lumen; when the sphincter relaxes, the lumen opens. At the junction of the urethra and bladder is the urethral sphincter, which, when in a draining state, closes the urethra to prevent urine leakage.
[0004] When a patient's urethral sphincter is damaged due to trauma, surgery, or other reasons, or due to damage to the nerves that control it, urethral insufficiency may occur, resulting in urinary incontinence. This incontinence worsens with increased abdominal pressure during activity, severely impacting the patient's quality of life.
[0005] To date, artificial urethral sphincter implantation is one of the most effective treatments for male stress urinary incontinence and treatment-resistant female stress urinary incontinence. It typically involves implanting an exogenous artificial sphincter device around the urethra, which closes or opens the urethra to control urine storage and urination.
[0006] Currently, most artificial sphincter devices require a three-piece set to achieve the function of closing and opening the urethra. The large number of accessories makes the steps of connecting the various components during surgery cumbersome. Furthermore, the appropriate pressure for closing the urethra comes from the elastic balloon. The manufacturing process of the elastic balloon and the water pump that provides the opening expansion device are both very demanding, resulting in very expensive products.
[0007] In summary, there is a need in the art to provide an expandable device that can overcome the shortcomings of the prior art. Utility Model Content

[0042] According to one embodiment of the present invention, an expandable device is provided in which a reservoir 1, a tubing 3, and an expansion component 4 are implanted into the patient's body. The reservoir 1 is buried under the body surface, with its first surface 11a facing the skin and subcutaneous tissue A. The expansion component 4 is fitted over the outside of the urethra (not shown in the figure). The expansion component 4 in its reservoir state compresses the urethra, thereby preventing incontinence. When the patient needs to urinate, he / she simply places the control block 2 on the skin and subcutaneous tissue A above the first surface 11a. The control block 2 magnetically attracts the partition 12, causing the elastic component 13 connected to the partition 12 to contract. The space in the first space 1a shrinks, and the space in the second space 1b expands. The reservoir sac 14 in the second space 1b expands to enter the reservoir state. The fluid in the expansion component 4 flows into the reservoir sac 14 through the tubing 3.

[0043] After the patient finishes urinating, the control block 2 is removed. After the control block 2 loses its magnetic attraction to the partition 12, the elastic component 13 pushes the partition 12 towards the second space 1b and squeezes the reservoir 14. The space in the first space 1a expands and the space in the second space 1b shrinks. The reservoir 14 is squeezed by the partition 12 and enters the discharge mode. The fluid in the reservoir 14 enters the expansion component 4 through the hose 3, causing the expansion component 4 to expand. The expansion component 4 in the storage mode squeezes the urethra, thereby preventing the patient from leaking urine.
[0044] According to one embodiment of the present invention, the expandable device can also be used to control defecation or control diet. In these application scenarios, the expandable component 4 needs to be fitted onto the esophagus or rectum.
[0045] The advantages of the inflatable device according to the present invention are: it does not require the use of an elastic balloon and a control pump, has a simple structure, greatly reduces the difficulty of product manufacturing process while improving performance, can greatly reduce product price, and is convenient and comfortable for patients to operate.
