TPN 400D Birth Assist Obstetric TENS Machine

As anyone who has ever given birth will attest, undergoing labour can be an extremely painful process. While there are pharmaceutical options for pain relief – such as obstetric epidurals or pethidine injections – these are known to have side effects that can affect both mother and baby.

The TPN 400D Birth Assist Obstetric TENS Machine provides you with another option, encouraging your body to produce a greater amount of its natural painkillers (endorphins). TENS therapy has no known side effects and is a proven method of managing pain during labour. This obstetric TENS machine is a dual channel unit that is both durable and easy to use.

What is TENS and How Does it Work?

TENS is an acronym for Transcutaneous Electrical Nerve Stimulation, which involves the stimulation of nerves by a mild electrical current passed through the skin. TENS machines can be used to relieve the pain associated with a number of conditions and usually work by having the user apply electrodes to the affected area.

When your TENS machine is switched on, the user will feel a slight tingling (which should not be painful). By stimulating the nerves, this electrical current encourages your body to release more natural painkillers, reducing your overall levels of pain without requiring outside elements.


Though TENS is not known to have any side effects, you should not place electrodes in the following places:

  • The front or side of your neck
  • Your temples
  • Your eyes or mouth
  • Your heart
  • Irritated, infected or broken skin
  • Varicose veins
  • Numb areas

In addition, you should consult a medical professional about the suitability of TENS if you have a pacemaker (or any other electrical or metal implant in your body) or if you have epilepsy or arrhythmia.
