Vacuum Constriction Device: What It Is & How to Use It

A vacuum constriction device (VCD) offers a non-invasive approach for individuals experiencing erectile dysfunction (ED). This external pump system aids in achieving and maintaining an erection. It is designed to facilitate blood flow into the penis, which is necessary for an erection.

What is a Vacuum Constriction Device?

A vacuum constriction device, also known as a penis pump, is an external medical tool used to help men attain and sustain an erection. The device typically consists of three main components: a clear plastic cylinder, a pump, and a constriction ring. The cylinder is designed to be placed over the penis.

The pump connects to the cylinder and is used to create a vacuum. The constriction ring is an elastic band that is placed at the base of the penis once an erection is achieved. This ring serves to trap the blood within the penis.

How the Device Works

The mechanism of a vacuum constriction device relies on creating a localized vacuum around the penis. Once the penis is placed inside the cylinder, the pump removes air, generating negative pressure. This vacuum effect causes blood to be drawn into the penile shaft, leading to engorgement and an erection.

After the penis becomes erect, a constriction ring is then slid from the cylinder onto the base of the penis. This elastic ring gently compresses the veins at the base of the penis, preventing the blood from flowing back out. This process enables individuals to achieve an erection firm enough for sexual activity.

Using a VCD: Step-by-Step and Safety Tips

Proper application of a VCD begins with applying a lubricant to the base of the penis before inserting it into the plastic cylinder. Once the penis is inside, the pump is activated to create a vacuum, drawing blood into the penis until an erection forms. It is important to use only the necessary amount of vacuum pressure to achieve an erection, as excessive pressure could cause injury.

After an erection is achieved, slide the constriction ring from the cylinder onto the base of the penis. The pump can then be removed. The constriction ring should remain in place for no more than 30 minutes to prevent potential damage or bruising to the penis. After use, the device should be cleaned thoroughly. Using the largest possible constriction ring that still maintains an erection is recommended for comfort and effectiveness.

Outcomes, Side Effects, and When to Consult a Doctor

Vacuum constriction devices produce an erection that is satisfactory for sexual intercourse. The erection will subside once the constriction band is removed. However, the erection achieved with a VCD may feel different from a natural erection, sometimes described as purplish in color, cold, or numb.

Potential side effects can include minor bruising or small areas of discoloration on the penile shaft, which are painless and resolve within a few days. Some users may experience a decrease in the force of ejaculation because the constriction band can trap semen. This is not considered dangerous, and the semen dribbles out after the band is removed. If persistent pain, unusual side effects, or a lack of effectiveness occurs, it is advisable to consult a healthcare professional.
