Embodiment Construction

[0011] The portable non-invasive neurogenic bladder treatment instrument of the present invention uses high-frequency stimulation to inhibit striated muscle contraction to realize the physiological urination process under electrical stimulation. This principle was discovered by Thuroff et al. through dog experiments. The bladder detrusor is a smooth muscle, and the external urethral sphincter is a striated muscle. The response characteristics of the two to the frequency of electrical stimulation are different. The contraction of the urethral sphincter is the strongest when the stimulation frequency is 33-50Hz, but fatigue will appear as the frequency increases, and the contraction force will decrease soon after reaching the peak. When the stimulation frequency is very fast, after several consecutive action potentials, the refractory period of the striated muscle cell membrane is prolonged, and no action potentials will occur for subsequent stimulations, thus appearing high-freq...

Abstract

The invention provides a portable non-invasive neurogenic bladder therapeutic apparatus that belongs to medical instruments field. The instrument adopts FPGA integrated circuit to generate a series of digital pulse signals, and imitates a series of physiological electrical pulse signal which are generated by micturition, the signals are transmitted to the acupuncture points on the skin around human bladder by two groups of ECG monitoring electrodesfor stimulating and controlling contractive muscle of bladder, so that diseases of increase of residual urine in bladder, urinary retention and urinary incontinence, etc,. The invention has advantages of small size, stable and reliable work, little in application condition, cheap price and portable.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a portable bladder treatment instrument. technical background [0002] Neurogenic bladder is one of the common functional bladder diseases in clinical practice. There are many reasons for its pathogenesis, such as spinal cord injury, central nervous system disease, side effects of certain drugs, etc. The main manifestations are increased residual urine, urinary retention and urinary incontinence. In addition, postpartum and excessive drinking may also affect the normal function of the bladder and lead to the occurrence of the above phenomenon. If it is not treated in time, it may cause upper urinary tract infection, which may lead to systemic infection and renal failure, resulting in death of the patient. Now, with the development of science and technology, although some invasive methods can be used to treat patients, such as inserting urinary catheters, implanting stimulators through su...
