Male sexual function assessment method based on electrical impedance tomography and monitoring device

Abstract

The invention discloses a male sexual function assessment method based on electrical impedance tomography and a monitoring device. In a region between two legs at the front side of boxers or briefs, a pressure monitoring pad, which is made from a flexible conductive rubber material having a piezo-resistive property, and a temperature sensor are distributed; by virtue of an electrical impedance tomography technology, the distribution of various electric conductivities when the interior of the pressure monitoring pad is exerted is measured, and subsequently, in accordance with the properties of the piezo-resistive material, pressure distribution on the pressure monitoring pad is reconstructed under the precondition of eliminating the influence of temperature on the electric conductivity of the piezo-resistive material. By virtue of the method and the device, an ejecting situation on a pant contact region in a male penis erection process and a changing process of the ejecting situation can be continuously and dynamically monitored and recorded, and the device and the method are especially suitable for monitoring a male night erection state, so that a monitored male sexual function is actually and objectively assessed. The male sexual function assessment method and the monitoring device for monitoring the penis erection state disclosed by the invention have the advantages of being natural and convenient to wear, low in influence on the mental state of a monitored object, capable of continuously monitoring for a long time, reliable and accurate in result and the like.

Description

technical field [0001] The invention relates to a method for evaluating male sexual function and medical electronic equipment thereof, in particular to a dynamic monitoring device which can be used for evaluating male sexual function. Background technique [0002] Male sexual dysfunction generally includes organic ED (Erectile Dysfunction) and psychological ED, such as organic impotence and psychological impotence, etc., and from the perspective of penile erectile function, psychological impotence patients may have A temporary, near-normal erection. Since the inhibitory effect of the cerebral cortex during waking is removed in the sleep state, nocturnal erection is not affected by psychological factors and can well reflect the patient's potential erectile function. Therefore, nocturnal penile tumescence (NPT) is clinically used as a diagnosis. The preferred method of ED, especially suitable for distinguishing between organic ED and psychological ED, it is a simple, practica...

Problems solved by technology

[0003] At present, there are a variety of male sexual function monitoring instruments at home and abroad, such as RigiScan and NEVA, and many domestic penile hardness monitors that imitate RigiScan. Although these monitors can display the whole process of penile erection at night, each has its advantages and disadvantages: RigiScan can measure the hardness and diameter of penile erection, but cannot identify the type of ED; NEVA can more intuitively display the type of ED (such as arterial insufficiency, venous leakage) in the penile erection graph, and NEVA can continuously measure the number, duration and length of penile erection , thickness and blood volume changes, the changes in penile blood volume can be indirectly obtained by detecting the electrophysiological impedance parameters of penile blood volume changes; however, NEVA indirectly reflects the sexual function of the monitored person, and cannot directly reflect its sexual function, and its accuracy still to be discussed

In addition, the above-mentioned monitoring methods, due to the limitation of the implementation principle, cannot obtain the axial force of the penis erection of the monitored person, and the axial hardness of the penis erection is the most important item in sexual intercourse.

More importantly, the above-mentioned evaluation and monitoring instruments all need one or more pressure detection rings to be put on the patient's penis, and special wires need to be connected to the recording box bound on the thigh; thus, ED patients not only It is extremely inconvenient to use and affects daily life. What is more serious is that it will increase the serious psychological burden and negative impact on the patients who already have psychogenic ED, which will lead to the subjective impact of the above-mentioned instruments on the sexual function evaluation results and the reliability. Insufficient

So far, the above two instruments have not been widely used clinically due to reasons such as inconvenient use, low reliability, complex system and high price.
