NeedleBay: the insulin pen needle case that helps you know if you’ve had your insulin

Did I take my insulin? One look tells you.

How NeedleBay helps with your insulin pen needles

NeedleBay is a pocket case for your insulin pen needles. No need to touch the needle. Up to four used needles stay locked inside until you can drop them into a sharps bin, the yellow box for used needles.

Here is what NeedleBay does:

Holds four needles ready to use. Each new needle waits in its own bay, with its seal still on.
Keeps your fingers away from the needle. You screw your pen onto the needle while it sits in its bay, and unscrew it back into the same bay after your injection.
Shows which of today’s injections are done. A used needle goes back in its bay, so one look tells you.
Locks used needles away. Up to four stay safely inside, in your pocket or bag, until you get to a sharps bin.

It helps prevent missed doses and double doses. No app, no batteries, nothing to charge. From £14.95, made in the UK.

Ways NeedleBay helps with insulin needles and injections

Forgetting a dose, carrying used needles, stiff hands, poor eyesight, or helping someone else. Pick a topic to see how NeedleBay helps.

“Did I take my insulin?”

Stop guessing. A used needle in its bay means that injection is done. It helps prevent missed doses and taking it twice.

How it helps your memory

Reduced dexterity, like stiff or shaky hands?

No tiny needle to grip. The needle is held in its bay, so you just screw your pen on and off. The used one stays behind.

Poor eyesight

Feel it as well as see it. A used needle has no seal, lids click shut, and every lift tab can be found by touch. Nothing to read.

Travelling with NeedleBay

How many do I need?

Four injections a day? One NeedleBay a day. Fewer? The same four bays last longer. More than four, or a day out? Take two.

Which pack is right for me?

A weekly injection pen

One pen, four doses, four bays. The used needle in its bay shows this week’s injection is done. Also take insulin? One NeedleBay for each.

Getting rid of used needles safely

When you are ready to dispose of the needles, open the lids and release the click‑lock. The used pen needles drop safely into your sharps bin.

How NeedleBay works as an insulin reminder

1. Load

Open the lids and pop in four new pen needles, seals still on. A click‑lock holds them in place.

2. Use

Screw your pen onto a new needle and lift it out. After your injection, screw the pen back into the same bay and unscrew. The used needle stays behind.

3. Check and empty

Use a GLP‑1 or weight‑loss injection pen?

NeedleBay holds GLP‑1 and weight‑loss pen needles too

Most weekly injection pens take the same screw‑on pen needles as insulin pens, and NeedleBay is made for those needles. Four new needles wait in their bays. After each injection the used needle goes back in its bay and stays locked away until you reach a sharps bin.

One case lasts a weekly pen’s month. A weekly pen holds four doses, and NeedleBay has four bays, so one case takes you from the first dose to the last.
One look tells you if this week’s injection is done. The used needle sits in its bay, so there is nothing to remember and nothing to write down.
Take insulin as well? Use one NeedleBay for each. The Twin Pack gives you one case for your daily insulin pen and one for your weekly pen, each with its own needles.

NeedleBay is for pens that take screw‑on pen needles. Some weekly pens have the needle built in and need no separate needles. If yours is one of those, NeedleBay is not for you.

Designed with healthcare professionals and people living with diabetes

NeedleBay was tried out in a study at Cardiff University with over 250 people. The results were looked at by the University of Reading and shared at a major diabetes meeting in Stockholm. In the study, most users said NeedleBay helped them keep track of their doses.

“NeedleBay has made many of my patients’ lives easier and supports safe and hygienic injection practice. For one patient in particular it has meant that district nurses no longer have to visit two or three times daily to administer insulin.”

Karen Pudge, NHS Diabetes Specialist Nurse

“Brilliant, quick and easy. NeedleBay is the best!”
Les Cobbett, 82

“Thank you to NeedleBay for saving my memory when trying to wrack my brain as to whether I have or haven’t done my injection. For a diabetic to forget their insulin can be a matter of life and death.”
Sally Landsborough

Quick answers

Is it hard to set up?

No. Open the lids, pop in four needles, close the lids. That’s it.

Will it fit in my pocket?

Yes. It fits a coat pocket, handbag or school bag.

Can I load it the night before?

Yes. Each needle keeps its own seal until you use it.

Does it work with GLP‑1 and weight‑loss injection pens?

Yes, if your pen takes screw‑on pen needles, which most do. The 4mm needles most people get on prescription fit insulin pens and GLP‑1 pens alike. Pens with a built‑in needle do not need NeedleBay.
