How is the Active model different from the Manual model?

The Active model uses a battery-powered motor pump for one-handed operation at the push of a button; the Manual model requires hand pumping. The erection mechanism and ring-based maintenance are otherwise the same.

Q: Can I use it while on anticoagulants?

Using a vacuum device while on anticoagulant therapy carries an increased risk of bruising; consult your treating physician before use.

Our medical expert says

“The therapeutic principle of the Active and Manual systems is the same: vacuum creates the erection, the constriction ring maintains it. The difference is in how they are operated – the Active uses a rechargeable, motorized pump that works one-handed at the push of a button. This is worth the extra cost when manual pumping is difficult: for hand joint problems, reduced strength or limited dexterity. I review the differences between the two systems in the buying guide.”

Realistic expectations: A vacuum system mechanically produces an erection and the constriction ring maintains it – it does not treat the underlying disease, it enables intercourse. Motorized operation makes use simpler but does not increase the therapeutic effect. Safety rule: the constriction ring should be kept on for no more than 30 minutes at a time.
This is not your device if: manual pumping is not a problem for you – then the Medintim Manual Erection System offers the same therapeutic principle at a lower price. If an erection occurs but quickly subsides, a constriction ring – Helpi Ring or Backup Ring – may be a considerably cheaper solution. For rehabilitation after prostate surgery the REHABI PVT is the targeted device.
Before you order: For persistent or severe complaints I recommend a thorough urological evaluation: erectile dysfunction can be caused by a treatable disease. In cases of anticoagulant therapy or bleeding disorders, 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 discoloration. The kit includes several constriction rings. After choosing the right size, additional parts can be purchased among accessories.

Who might it be suitable for?

Quick and stable erection

The motor pump creates vacuum at the push of a button, so no manual pumping is required. This disturbs the intimate situation less.

If you cannot take the "blue pill"

Some heart medications make oral erection drugs unsuitable, in others the medication may be ineffective or cause side effects. The mechanical vacuum solution can replace medication in such cases.

If a chronic disease causes erectile dysfunction

Erectile dysfunction often coexists with conditions such as diabetes, high blood pressure, cardiovascular disease or neurological disorders. In these cases a vacuum device can be a drug-free alternative after medical consultation. For rehabilitation after prostate surgery see the Rehabi PVT penis trainer.

How does it work? – Mechanism of action

The physiological basis of an erection is blood flowing into and expanding the corpora cavernosa. A vacuum device mechanically supports this process: the motor pump creates reduced pressure (vacuum) inside the tube, producing negative pressure around the penis that promotes local blood inflow and erection formation.

After achieving an erection, placing a constriction ring at the base of the penis reduces blood outflow, so the erection persists after removing the tube – for up to half an hour. The device contains no active pharmaceutical ingredient, so its effect does not pharmacologically burden the body.

Frequently asked questions

How long can I keep the constriction ring on?

The constriction ring may be kept on for a maximum of 30 minutes, never longer. If you experience any pain, numbness or discoloration, remove the ring immediately.

Can I use it while on anticoagulants?

When on anticoagulant therapy or if you have a bleeding disorder, using a vacuum device carries an increased risk of bruising. In such cases consult your treating physician before use.

How is it different from the manual model?

The difference is how the vacuum is created: the Active Erection System uses a rechargeable motor pump (one-handed, at the push of a button), whereas the Manual Erection System is manual. The erection mechanism and ring-based maintenance are identical for both.

Is the use painful?

With proper use it is not painful. At first the vacuum and the constriction ring may feel unusual, but the lubricant gel and correct ring size help ensure comfortable use.

Can the product be returned?

The product belongs to the category of intimate hygiene devices; for health protection and hygiene reasons we only accept returns for unopened, sealed packaging (Government Decree 45/2014. (II. 26.), §29 (1) e)).

How to use? Step by step

Preparation

Apply the supplied lubricant gel to the tube rim and to the base of the penis. Choose the constriction ring size that fits you, and check that the pump battery is charged.

Create vacuum at the push of a button

Place the penis in the tube, press the tube rim against the body, and start the motorized pump. The vacuum builds gradually, causing local blood engorgement and resulting in an erection.

Applying the ring

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

Cleaning and storage

After use, the tube and rings are easy to clean with warm water. All components can be stored in the supplied bag until the next use.

Important information

Erectile dysfunction often has an underlying treatable disease, so the cause of symptoms should always be investigated by a physician — a vacuum device addresses the symptom but does not treat the underlying cause. Use the product only according to the user manual and only as an adult. The product is an intimate hygiene device and can only be returned if unopened.

This description does not replace medical advice. For persistent or unexplained erectile dysfunction, consult your physician or urologist. CE medical device certification (Class I).
