We have been contacted by a local pharmacy, that explained us its difficulties in finding various medical equipment, due to the current emergency state. To date, the most significant item which is very difficult to find is a tool called airlock, in the version used for home oxygen therapy.
Airlock for home oxygen therapy.
An oxygen airlock is a humidifier which is placed between the air cylinder and the patient, to avoid the excessive desiccation of the respiratory tracts mucous membranes.
In synthesis, an airlock is a “receptacle” that contains a liquid, usually physiological water. Using a cylinder, in this liquid is injected some oxygen through a cannula equipped with an end that works as the oxygen dispenser. Once “filtered” by the liquid, the oxygen flows out automatically from the second hole, and is then inhaled by the patient.
Since the airlock is a simple tool in its structure, we have been asked to participate in the development of an alternative system. Our Team Engineering has immediately taken up the challenge by offering its resources, even though operating in a completely different field of activity from that of our company.
Developing the project.
First of all, we analysed the options available to us and the materials which could have been used. The biggest difficulty in the developing of the project comes from the fact that many businesses are currently not operative or don’t have many of the components that could be useful to the cause, especially those belonging to the health and medical gamma.
We then undertook from one side the designing of components that we would have produced through 3D printing, and from the other we started supplying from usual suppliers and new everyday materials, easier to obtain, that could be used at least for food purposes. The project then resulted in the developing of a prototype composed by:
- Polyethylene graduated rectangular bottle suitable for food contact, usually used for sampling of liquids.
- Polypropylene stopper associated to the bottle modified with a hole.
- 3D printed insert of the stopper, equipped with entrances for the oxygen cannula and seal seat.
- White alimentary EPDM tailored-made seal.
- Oxygen dispenser realised through 3D printer to allow the oxygen to fragment the bubbles flowing out from the cannula.
- Sicurlive Group is not an operator in the medical world.
- The project results functional, but remains completely lacking in certifications.
- We wanted to share this idea so to give the opportunity to develop, test, evaluate and eventually certificate it.
- We share in attachment the drawings and the technical specifications of the entire project.
- We suggest you to seek the collaboration of specialized and competent technical personnel, and to replicate the project only when no other alternative is available.
If needed, Sicurlive Group remains available for support and further details.
