Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

Oxygen Delivering System I: Nasal Cannula and Face Mask

The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Administering Oxygen by Mask

Administering Oxygen by Mask

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:

Area of Science:

Occupational Health and Safety
Biomedical Engineering
Materials Science

Background:

The protective efficiency of filtering dust respirators is determined by filter material properties and half mask frame design, which impacts facial fit.
Studies on the "Lepestok 40" dust respirator identified significant air leakage issues due to gaps along the obturation strip.
Inadequate facial fit compromises respirator effectiveness, necessitating design improvements.

Purpose of the Study:

To develop an improved dust respirator with enhanced protection and usability.
The primary goal is to optimize the half mask frame design to minimize air leakage.
To create a respirator that offers a superior seal against airborne particulates.

Main Methods:

A systematic design scheme was employed, including analysis of operating conditions.
Facial anthropometric measurements of potential users were collected and analyzed.
3D modeling of the half mask frame was performed, incorporating variable geometry for adjustable fit.
Laboratory testing was conducted to evaluate the protective properties of the developed respirator.

Main Results:

A novel half mask frame design for dust respirators was developed.
The new design features variable geometry achieved through special attachment points.
This allows for size adjustment based on individual user's facial anthropometric dimensions.
The improved design aims to significantly reduce air leakage.

Conclusions:

The developed half mask frame design offers a customizable and tighter facial fit.
This innovation is expected to increase the protective efficiency of dust respirators.
Considering enterprise-specific anthropometric data enables the creation of tailored respirator solutions.
