COVIDIEN: technical information about the products

Patient safety – in our focus

Our company offers one of the largest portfolios of products designed to help reduce morbidity associated with Nosocomial Infections (NI) and specifically those affecting the respiratory tract.

Our mission is to work in partnership with healthcare professionals in order to win the race against hospital acquired infections and offer patients a fast and safe route to recover quickly.

Products for Patient Safety – Airway management

TaperGuard™ and SealGuard™

Endotracheal and Tracheostomy Tube

One of the major causes of bronchopulmonary infections in long-term ventilated patients is aspiration from the subglottic space. Drainage of the subglottic space can significantly reduce the risk of infection in the airway during prolonged ventilation. Several studies have demonstrated that drainage of the subglottic space using the Mallinckrodt™ Evac technology can reduce the incidence of Nosocomial Pneumonia in ICU by up to 75% (1).

The TaperGuard™ and SealGuard™ tubes are equipped with an additional lumen for improved access to the subglottic space. The lumen is integrated into the wall of the tracheal tube ending in a dorsal opening proximal to the cuff. It allows suctioning of the subglottic space and the simple and rapid removal of secretions from this critical area. The additional lumen can be connected to a suction device to allow automatic suctioning of the subglottic space.

Products for Patient Safety – Airway management

TaperGuard™ and SealGuard™

Endotracheal and Tracheostomy Tube

The SealGuard™ and TaperGuard™ brands stand for the latest in cuff technology.

The newly developed taper-shaped cuff design may help reduce microaspiration.  The combination of the Mallinckrodt™ Evac technology with the SealGuard™ and TaperGuard™ cuff technology also reduces the risk of Ventilator associated pneumonia (VAP).

Products for Patient Safety – Mechanical ventilation

PURITAN BENNETT 840 ™

Ventilator

The PURITAN BENNETT 840™ ventilator offers the latest ventilation modalities such as:

 Non-Invasive Ventilation, avoiding endotracheal intubation

 Volume Ventilation Plus (VV™ +) and Proportional Assist™* Ventilation (PAV™*+) to reduce the mechanical ventilation time.

In addition, the design of the PURITAN BENNETT 840™ ventilator is such that it may help protect patients, carers, family members and the environment from microbial contamination.

The integrated heated exhalation/ isolation systems incorporated in the ventilators are highly effective at limiting contact at the bedside from the patient’s exhaled ventilatory gas. Prior to entering into the internal circuitry of the ventilator, the patient’s exhaled air first passes through a viral and antibacterial filter. The filter, maintained at an elevated temperature, maximizes the vapour phase of the exhaled humidity and reduces the condensate from the gas. Filtering the exhaled gas before it reaches any of the internal components of PURITAN BENNETT ventilators also helps reduce the risk of cross-contamination from patient to patient. No filters need to be added to the circuit to protect the patients and the interior of the ventilators from contamination.

Under rigorous test conditions, the expiratory filters (PB D-X 800) used in the PURITAN BENNETT 840™ ventilator have shown a 99.999% filtering efficacy, when subjected to viral challenges with bacteriophages measuring 27 micron. The ventilator’s heated filtration system showed greater than 99.99999% efficacy against passage of aerosol particles as small as 2.8 micron. The performances of the filtering system offer an effective protection against SARS (Severe Acute Respiratory Syndrome), Avian Influenza (H5N1) and Tuberculosis.(1)

Certain patients pose challenges when obtaining reliable SpO2   readings: e.g. poor perfusion, vasoconstriction. As part of the innovative OxiMax™ pulse oximetry system, the Max-Fast™ forehead sensor offers significant advantages in patient safety monitoring. This is because it often works when conventional sensors fails, giving you an effective solution for the most challenging patients.(1) The Max-Fast forehead sensor is more responsive than conventional sensors when patients are poorly perfused. It detects changes in SpO2 typically 1 to 2 minutes earlier than digit sensors during vasoconstriction, and in some case beats digits sensors by as much as 3 minutes!(2) This enables you to react sooner to hypoxemic events as timing can be critical for your patients.
