Urethra valve driven by wireless power shape memory alloy (SMA)

Abstract

The embodiment of the invention discloses a urethra valve driven by a wireless power shape memory alloy (SMA). The SMA is short for a shape memory alloy. The urethra valve is used for solving the technical problems that in the prior art, urinary incontinence, caused by urethra sphincter disfunction, of a patient cannot be solved effectively by a conservative treatment, an operative treatment, nursing measures and the like. The urethra valve comprises a magnetic coupling resonance unit, an SMA spring, a valve element, a first permanent magnet, a second permanent magnet and a valve body. The valve body is of a hollow frame-shaped structure; the SMA spring, the valve element, the first permanent magnet and the second permanent magnet are arranged in a valve cavity of the valve body; and the valve body is used for being fixed on a pubis position of a human body. One end of the SMA spring is connected with the valve element, and the other end of the SMA spring is fixedly connected with the inner wall of one side of the valve cavity; the first permanent magnet adjoins the side, unconnected with the SMA spring, of the valve element; one side of the second permanent magnet adjoins the inner wall of the other side of the valve cavity and the other side of the valve cavity is opposite to the side connected with the SMA spring; and the gap between the first permanent magnet and the second permanent magnet is used for penetrating through a urethra position of the human body.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a urethral valve driven by a wireless power supply SMA. Background technique [0002] Urinary incontinence is clinically defined as the loss of self-control of urination due to bladder sphincter damage or neurological dysfunction, which causes urine to flow out involuntarily. Urinary incontinence is a common and frequently-occurring disease that can occur at any age and gender, especially women and the elderly. Urinary incontinence can lead to complications such as perineal and sacrococcygeal dermatitis and pressure ulcers, which not only makes people uncomfortable, but also affects the patient's quality of life for a long time and seriously affects the patient's mental health. [0003] There are many causes of urinary incontinence, among which functional defect or trauma of urethral sphincter is one of the main causes of urinary incontinence. For urinary incontinence caused by...
