Erectile dysfunction (ED) is a common disease that affects men’s health around the world, and its causes are complex and diverse. From a physiological perspective, atherosclerosis, which leads to an insufficient blood supply to the corpus cavernosum of the penis; nerve damage caused by diabetes; and high blood pressure, which damages endothelial function, are all “culprits” that induce ED. In terms of psychological factors, long-term stress, anxiety, and strained relationships can also cause ED by interfering with signal transmission from the brain’s sexual center. Traditional treatments, such as drug therapy, have limitations, including short-term efficacy and obvious side effects. Surgical treatment carries high risks and requires a long recovery period. Our shock wave therapy device offers a new approach to ED treatment.

Product Features

Small and Light
Our portable shock wave therapy device is small and light, weighing only 1.9kg. Whether it is used at home or carried with you on a business trip, it is burden-free, allowing rehabilitation therapy to be unrestricted by space and convenient health protection to be started at any time.

One Machine for Multiple Uses
Our shockwave therapy device contains 6 modes for different ED, which can be selected according to the actual situation of the individual.

One-button Start/stop
After connecting our shock wave therapy device to the handle, turn on the power, press the button on the handle to start working, and press it again to stop. The operation is very simple

Adjustable Parameters
The working intensity of our shock wave therapy device can be adjusted between 25-105mj, and the frequency can be adjusted between 1-16hz. It can be adjusted at any time according to personal tolerance.

Easy to Replace the Working Heads
Aim at the threaded opening and tighten clockwise. If you feel the impact force is too great, you can adjust the parameters to reduce the intensity.

Ergonomic Handle Design
The handle of our shock wave therapy device is made of a more skin-friendly metal material with a smooth arc and heat dissipation holes at the front and rear ends, making it more comfortable to hold.
6 ED Treatment Modes

Mild Vascular ED Pattern
Applicable population/scenario: IIEF-5 score 12-16 points, PSV 25-29cm/s, mild hypertension/hyperlipidemia, occasional smoking, BMI 25-30
Energy intensity: 15-20mj
Frequency: 8-10Hz
Number of single shocks: 1500 times
Duration of single treatment: about 20-30 minutes
Course of treatment: 6 times (once a week)
Treatment logic:Focus on improving endothelial function, stimulate VEGF release through low energy, and promote the initial establishment of collateral circulation.
Cooperate with lifestyle intervention (such as smoking cessation, weight loss)

Moderate Vascular ED Pattern
Applicable population/scenario: IIEF-5 score 8-11 points (severe ED), PSV 20-24cm/s, with clear arteriosclerotic plaques (such as local stenosis of the dorsal artery of the penis).
Energy intensity: 20-25mj
Frequency: 10-12Hz
Number of single shocks: 2000 times
Duration of single treatment: about 30-40 minutes
Course of treatment: 8 times (2 times a week, intensive in the first 4 weeks)

Severe Vascular ED Assistance Mode
Applicable population/scenario: IIIEF-5 score <8 points, PSV <20cm/s, or combined with severe venous leak (ultrasound shows EDV>5cm/s),As a transitional treatment before surgery (such as vascular reconstruction or prosthesis implantation), it can delay disease progression or improve postoperative recovery.
Energy intensity: 25-30mj
Frequency: 12Hz
Number of single shocks: 2500 times
Duration of single treatment: about 40-50 minutes
Course of treatment: 12 times (2 times per week for the first 6 weeks, 1 time per week for the next 6 weeks)

Mixed Vascular + Psychological ED Pattern
Applicable scenarios: Erectile failure due to vascular disease, which leads to anxiety (such as increased psychological pressure after middle-aged men first experience ED).
Energy intensity: 20mj (adjusted according to personal situation)
Frequency: 10Hz
Duration of a single treatment: about 25-35 minutes
Treatment course: 8 times (shock wave) + 4 times psychological counseling

Dedicated Mode for Diabetic ED
Pathological characteristics: Diabetes causes vascular endothelial damage + neuropathy, poor repair ability.
Energy intensity: 12-20mj (adjusted according to personal situation)
Frequency: 6-8Hz (low frequency reduces stimulation)
Treatment site: increase the dorsal nerve area of the penis (reduce nerve pain hypersensitivity)
Single treatment duration: about 30 minutes
Treatment course: once a week, a total of 10-12 times

Postoperative Neurogenic ED Rehabilitation Mode
Applicable population: 3-6 months after radical prostatectomy, with erectile dysfunction (nerves not completely severed). Energy intensity: 12-18mj (adjusted according to personal situation)
Frequency: 5Hz (ultra-low frequency stimulation nerve repair)
Single treatment duration: about 20-25 minutes
Course of treatment: 10 times (starting 3 months after surgery, once a week, for 10 weeks)
Note: The above six treatment modes all need to adjust parameters according to their own conditions
Transmitter Heads Introduction
Energy conduction mechanism
After the shock wave is emitted from the plane end, it propagates into the tissue in a nearly parallel wavefront, and the energy distribution is relatively uniform, but as the depth increases, the energy decays faster.
Physical action characteristics
Mechanical stress effect: The plane has a large contact area, which produces extensive mechanical stimulation to the skin and subcutaneous tissue, can loosen superficial fascia adhesions (such as tissue fibrosis around the dorsal nerve of the penis), and improve surface blood circulation.
Cavitation effect: Microbubbles burst at the interface between tissue fluid and gas (such as the surface of vascular endothelium), promote the release of nitric oxide (NO) by vascular endothelial cells, and enhance vasodilation function.
Application logic for treating ED
Mainly targeting the nerve endings and microvessels in the epidermis and superficial fascia of the penis, improving the sensitivity and microcirculation of the surface tissue, and indirectly improving the blood flow response during erection.
Energy conduction mechanism
After the shock wave emitted by our instrument is emitted from the end face of the cylinder, it is concentrated into a beam through geometric focusing (such as the cylindrical arc surface design) to propagate to the deep tissue, forming a “focusing point” (the focal depth can reach 3-5cm), and the energy density is significantly enhanced at the focus.
Physical action characteristics
Mechanical stress and tissue damage repair:Our instrument focuses energy to produce stronger mechanical stimulation in deep tissues (such as the tunica albuginea of the corpus cavernosum and the main blood vessels of the crura of the penis), which can induce tissue micro-damage, activate fibroblasts and stem cells, and promote collagen remodeling and angiogenesis (such as stimulating the proliferation of endothelial cells in the corpus cavernosum sinus).
Vascular regeneration effect:The high-energy shock wave at the focus can directly act on the occluded arterioles or veins, breaking up the microthrombi in the blood vessels through the cavitation effect, while stimulating the secretion of vascular endothelial growth factor (VEGF) and promoting the establishment of collateral circulation (such as the formation of anastomotic branches between the deep arteries of the penis and the corpus cavernosum vessels).
Neuromodulatory effect:The impact on deep nerve fibers (such as the branches of the pelvic plexus) may inhibit abnormal nerve signal conduction (such as nerve damage repair in diabetic ED), while enhancing the nerve conduction efficiency of normal erectile reflexes.
Application logic for treating ED
Aiming at the core pathology of ED – insufficient blood supply to the cavernous body or nerve damage, our shock wave device specifically for ED directly acts on deep blood vessels and nerves by focusing energy, improving erectile function from the physiological root (such as vascular reconstruction for arterial ED and nerve repair for neurogenic ED)
