Medintim Manual Erection System

Our medical expert says

“Erectile dysfunction is not something to be ashamed of, nor is it necessarily an inevitable part of ageing — often it is a symptom of a treatable underlying condition. Vacuum devices have been recognised as a non-invasive solution for erectile dysfunction for decades, and they can be used without medication. The Manual version works with a hand pump: this is the more affordable entry option between the two Medintim systems. However, investigating the background of erectile dysfunction is always advisable.”

Realistic expectations: The vacuum system mechanically creates the erection, and the constriction ring maintains it — so it does not treat the underlying disease, but it makes intercourse possible. The first uses require practice: typically it becomes routine after a few tries. Safety rule: keep the constriction ring on for no more than 30 minutes at a time.
Not the right device for you if: hand-pumping is difficult for you — for example due to hand joint problems, reduced strength or limited dexterity — the motorised Medintim Active Erection System works one-handed at the push of a button. If an erection is achieved but quickly subsides, a constriction ring — Helpi Ring or Backup Ring — may be a much cheaper solution. For post-prostate-surgery rehabilitation the REHABI PVT was developed specifically.
Before you order: For persistent or severe symptoms I recommend a thorough urological assessment: a treatable disease may be responsible for the erectile dysfunction. If you are on anticoagulant therapy or have a bleeding disorder, or if you are prone to prolonged painful erections (priapism), use only after medical consultation. Remove the ring immediately if you experience pain, numbness or discolouration. Constriction rings in multiple sizes are included. You can replace rings in the correct size under accessories.

Who might this be suitable for?

For erectile dysfunction due to chronic illness

Erectile dysfunction often accompanies conditions such as diabetes, high blood pressure, cardiovascular disease, elevated blood lipid levels, or neurological disorders (e.g. multiple sclerosis). In such cases the vacuum device can be a drug-free alternative after consulting your doctor.

If you cannot take the “blue pill” or it doesn’t work

Some heart medications preclude the use of erection-promoting tablets; in other cases the medication does not produce the expected result or causes side effects. The mechanical vacuum solution may be an option here as well — in consultation with your treating physician.

After prostate surgery or other causes

Prostate disease or surgery, penile vascular disease, hormonal disorders or lifestyle factors (smoking, alcohol) can also lead to erectile dysfunction. Note: for post-operative rehabilitation the Rehabi PVT penis trainer was developed.

How does it work? – Mechanism of action

The physiological basis of an erection is blood flowing into the corpora cavernosa of the penis, causing them to expand. The vacuum device mechanically supports this process: the low pressure (vacuum) created in the tube produces negative pressure around the penis, which promotes local inflow of blood and the formation of an erection.

After achieving erection, the constriction ring placed at the base of the penis prevents blood outflow, so the erection can persist after the tube is removed — for up to half an hour. Because the device contains no medication, its effect does not impose a pharmaceutical burden on the body.

Frequently asked questions

How long can I keep the constriction ring on?

The constriction ring may be kept in place for a maximum of 30 minutes, never longer. Prolonged or overly tight use should be avoided — if you experience any pain, numbness or discolouration, remove the ring immediately.

Can I use it while on anticoagulant therapy?

If you are receiving anticoagulant treatment or have a bleeding disorder, using a vacuum device requires extra caution due to the risk of bruising. In such cases, be sure to consult your treating physician before use.

Is the use painful?

When used correctly it is not painful. The vacuum and the constriction ring may feel unusual at first, but the lubricant gel and selecting the correct ring size help ensure comfortable use. Always build up the vacuum gradually.

What is the difference between the manual and motorized model?

The Manual Erection System operates with a hand pump, which is simple and reliable. If you prefer one-handed, easier operation, the Active Erection System works with a battery-powered motor pump and can assist erection in as little as one to one and a half minutes.

Is the product returnable?

The product belongs to the intimate hygiene device category, therefore for health and hygiene reasons we accept returns only in unopened, sealed packaging (45/2014 Government Decree, Section 29 § (1) e)).

How to use? Step by step

Preparation

Apply the supplied lubricant gel to the rim of the tube and to the base of the penis — this helps sealing and comfortable use. Select the constriction ring size that suits you.

Creating the vacuum

Place the penis into the tube and press the tube's end against the body. By repeatedly operating the hand pump a vacuum is created gradually, causing local blood engorgement and producing an erection.

Applying the ring

After achieving erection, slide the ring on the tube to the base of the penis, then remove the tube. The ring maintains the erection — for a maximum of 30 minutes.

Cleaning and storage

After use the device is easily cleaned with warm water. All components can be stored in the supplied bag until the next use.

What do you get in the package?

1 pc Vacuum tube (200 mm length, 53 mm inner diameter)
1 pc Manual vacuum pump
Penis rings in multiple sizes (9, 12, 15, 18 and 21 mm diameter)
1 pc Lubricant gel (50 ml)
1 pc Carrying bag

Spare parts and accessories

All components of the device — including the four different-sized constriction rings — can be replaced separately even after years. The lubricant gel is also available as an accessory for regular use.

Important information

Erectile dysfunction often has an underlying treatable disease, so the cause of the symptom should always be investigated by a physician — the vacuum device provides symptomatic relief and does not treat the underlying cause. Use the product only according to the instructions and only as an adult. The product is an intimate hygiene device and can only be accepted for return in unopened packaging.

This description does not replace medical advice. In cases of persistent or unexplained erectile dysfunction, consult your treating physician or a urologist. The device has CE medical device certification (Class I).
