Negative Penile Pressure Erection Aid is primarily an extracorporeal device that promotes penile erection through non-invasive means to accomplish sexual intercourse. With a negative pressure penile abdominal erection aid, the penis is placed in it before intercourse, and by means of the negative pressure within it, the arterial vessels around the penis are expanded, increasing the corresponding blood supply and achieving the purpose of promoting erection. Afterwards, a ring is applied at the root of the penis to prevent venous return, prolonging the time of erection and completing the entire act of sexual intercourse, which is widely used in the clinic. The application of the corresponding equipment should pay attention to the condition of the entire penis, no organic lesions, no surface mucosal damage, and standardized application under the guidance of clinicians. Once after the application of penile pain, discomfort or local damage, need to consult a doctor in time to observe, under the guidance of clinicians for standardized treatment.
