Describe what you intend to do and how you'll do it in one sentence (required 250 Characters)

Worxwell Innovation aims to develop Ek-ject to empower caregivers to administer vaccines by themselves and reduce dependence on immunisation camps in developing countries. This will increase acceptance and increase demand of vaccines.

Explain the idea (less than 2,000 characters)

1) By developing a better self service vaccine applicator, we aim to empower caregivers and reduce the load on immunisation camps. By making the process of immunisation less time consuming and more accessible, we aim to increase acceptance of vaccines among caregivers and assure them with a safe and hygienic vaccine delivery system. 2) In most developing countries, caregivers lead busy lifestyles and might not be able to take their kids to immunisation camps. they also have concerns regarding hygiene and disposal of needles. It would also be less intimidating for kids if a know person(caregiver) administers the vaccine. 3) Ek-ject is made using "blow-fill-seal" technique that packs the vaccine in a sterile environment. The device does not need secondary packaging. The needle cover can be simply twisted to remove and open. When the bulb on the dose chamber is pressed to inject, it collapses inward to evacuate all the liquid in it. It can not be brought back out and reused. This also makes sure that the entire dose is fulfilled. After use, the top cap is locked into place using a folding hinge mechanism built into the device to cover the needle.this prevents needle pricks while disposing. Since some parts of the package like needle cover and dose chamber are broken/change shape after use, so the same package can never be repacked or reused.

Which part(s) of the world does this idea target?

  • Northern America
  • Central Asia
  • Eastern Asia
  • South-eastern Asia
  • Southern Asia
  • Western Asia

Geographic Focus (less than 250 Characters)

The idea caters to most developing and developed countries where caregivers lead busy lives and are conscious about hygiene and needle reuse.

Who are your end users and how well do you know them? (750 characters)

The end users of the product are caregivers themselves. Caregivers are the people who take care of the kids and bring them for immunisation. In most developed and developing countries the caregivers lead busy lives and are conscious about hygiene and safe disposal. They can learn use the simple applicator by following basic intuitive steps . Since the device is sterile and prefilled, they just have to insert it at a right angle on one of the muscle groups and press the dose chamber. After use they can cover the needle with the top cap and safely dispose the applicator.Kids will also be less intimidated as they know the caregiver and the form factor of the device is smaller and different than an injection.

How is the idea unique? (750 Characters)

This idea is different from many other innovations in their field as it uses a very low cost technique of manufacturing i.e. Blow fill seal technique. This also ensures safety and sterility till it reaches the end user even with out the need for secondary packaging. While innovations in this space address needle reuse issue by cutting the needle, Ek-ject avoids reuse as the needle is moulded in the applicator. Tampering is easily detected. The needle is covered by a cap after use for safe disposal. The collapsing dose chamber ensures fixed amount of drug delivery with just a simple pressing of the bulb. The device make the process simple and easy enough for caregiver to use themselves without assistance or instructions.

Just thought of this while re-reading you idea that Ashley Tillman pointed out about the idea. I felt you might want to ponder over it vivec rehman 
A lot of the vaccine we get today come in vials and then are mixed with saline just before administration. In that scenario I was curious to know how would the pre-sealed vaccine pouch work. Just some food for thought.

This could be a good reference.

You are right. What you are referring to are multi dose vials. They have dried drug in an ampule which is mixed with saline using a syringe and mixed. The same syringe is used to draw the liquid drug and inject. Due to safety, efficiency and skill related issues of the multi dose vials, since 2012, organisations like CDC are actively promoting prefilled syringes for vaccination.

The prefilled syringe is a replacement to the multi dose vials that Ashley is talking about.
Multi dose vials were used in mass vaccination programmes as they need less storage space (as they are dry) but take more time, effort and skill to administer and are prone to safety hazards like needle pricks and reuse.

From my personal experience, our physician himself suggested my mother prefilled syringes as she wanted to vaccinate us herself since she was concerned about safety at public vaccination events.
