1. Description of the Vitalograph Pneumotrac

The Vitalograph Pneumotrac in association with the Spirotrac PC based software is a spirometer designed for lung function testing in a variety of environments, e.g. hospital wards, occupational health centres and private homes. The Vitalograph Pneumotrac device is designed with desktop ease of use in mind – tidy desktop unit with state of the art communications capability in order to co-ordinate with Spirotrac. The long proven Fleisch flowhead is used for testing and has a resting location on the device.

The main components for the Vitalograph Pneumotrac are shown in Figure 1.

Warning: No modification of this equipment is allowed. Any unauthorised changes to the Pneumotrac device may compromise product safety and/or data and as such Vitalograph cannot be held responsible and the device will no longer be supported. 

 

1.1 Indications for use

The indications for use of the Vitalograph Pneumotrac (in conjunction with Spirotrac) is in the simple assessment of respiratory function through the measurement of dynamic lung volumes i.e. spirometry. Its primary functions are;

  1. Stand alone spirometric measures using single breath or multiple-breath testing techniques, display and record lung volumes and flow rates (including FIVC, FVC) and it’s subdivisions, In- and Expiratory Flow rates (PEF, FEFx, etc), and Pre-post testing (e.g. B.D.).
  2. Display a single subject’s demographic data entered by the user.
  3. Produce reports, typically with measured spirometry data compared against predicted values (Z-score and %Pred).

In a clinical setting, the measurements obtained from a lung function test form part of the various findings of a physician in the detection, diagnosis and control of chest diseases. Spirometry may support or exclude diagnosis, but it cannot make one.

Spirometers are also used in non-clinical settings such as occupational health screening where no clinical judgement is made, suspect findings always leading to a referral to a clinician.

7. Cleaning Instructions

7.1. Cleaning and Disinfecting the Vitalograph Pneumotrac

External parts of the Vitalograph Pneumotrac require cleaning, i.e. the removal of visible particulate contamination. The parts of the Vitalograph Pneumotrac that make up the flowhead, which comes into contact with subjects being tested, also require disinfecting. A spirometer is not designed as a ‘sterile’ device.

For spirometry testing a new mouthpiece should be used for each subject (either SafeTway or BVF).  Vitalograph recommends use of a BVF to protect both device and subject. A delay of at least 5 minutes should be allowed between subjects to allow settling of previously aerosolized particles in the measuring device.

In the event of visible contamination of the flowhead cones or flowhead element, they should be cleaned or disinfected as described in the accompanying table. The flowhead conditioning meshes should be replaced in the event of damage, or if visibly contaminated/blocked.

Where a BVF is used, the flowhead cone and front flowhead conditioning mesh should be cleaned and disinfected at least monthly or every 100 subjects (500 blows).  The frequency and extent of cleaning and disinfecting of the flowhead is dependent on the Facility's Risk Assessment, usage and test environment.

It is recommended that the complete flowhead and flowhead connection tube be replaced annually.

Table of Materials Used & Cleaning/Disinfection Methods

This listing of materials used is given to provide users with information to allow the assessment of other cleaning and disinfecting procedures available in the facility on this device.

Part Material Clean/ Disinfect Autoclave Recommended Disinfectants
Case Exterior ABS Clean No

Wiping with a 70% isopropyl alcohol impregnated cloth provides a suitable form of cleaning and low-level disinfection. This may be preceded by cleaning with an anti-static foam cleaner if necessary.

White Flowhead Tube Silicone Rubber Clean Viable
Fleisch Element Aluminium, Stainless Steel Clean Viable Where required, it is recommended to disinfect by immersion in sodium dichloroisocyanurate solution at 1000 ppm concentration of free chlorine for 15 minutes (see section above for recommended cleaning/disinfection method for the Vitalograph Pneumotrac Flowhead)

Parts of the flowhead identified as viable for autoclave may alternatively be disinfected by autoclaving at 134?C for 3 minutes or 120?C for 20 minutes.
Flowhead Body Aluminium & Acetyl Clean & Disinfect No
Flowhead Cone TPX Clean & Disinfect Viable
Flowhead End Cap TPX Clean & Disinfect Viable
Flow Conditioning Meshes Acetyl and Polyester Disinfect No


Definitions of cleaning and disinfection are as defined in “Sterilization, Disinfection and Cleaning of Medical Equipment: Guidance on Decontamination from the Microbiology Committee to Department of Health Medical Devices Directorate, 1996”.

Recommendations for chemical disinfectants are derived from the PHLS publication “Chemical Disinfection In Hospitals 1993”.

 

7.2. Disassembling the Fleisch Flowhead

  1. Remove the cone and the end cap from the flowhead.
  2. Remove the flow conditioning meshes from inside the cone and the end cap, and examine them for damage or contamination.  If they are damaged or blocked, discard.
  3. To remove the flowhead body from the fleisch element, place the fleisch element on a hard, flat surface with the largest diameter at the top. Push down on the flowhead body with thumbs and forefingers until it reaches the flat surface. A final pulling and twisting action will separate the parts.

  4. Clean each separate part of the flowhead by washing in a mild detergent and removing particulate contamination. To clean the fleisch element, swill vigorously in water with mild detergent or use an ultrasonic bath. Do not attempt to “rub” or “scrub” at capillaries. The flowhead body (7) does not require disinfection, but may be cleaned/disinfected with the rest of the flowhead for convenience.
  5. Rinse all parts in clean water.
  6. Disinfect by immersion in sodium dichloroisocyanurate (NaDCC) solution at 1,000 ppm concentration of free chlorine for 15 minutes. Prepare disinfectant solution as directed in the manufacturer’s guidelines.
  7. Rinse with very hot water to aid later drying.
  8. Leave to dry completely before reassembling. Drying the fleisch element components may require placing them in a warm place overnight. A drying cabinet is ideal.

Always follow the safety guidelines given by the manufacturer of cleaning and disinfectant chemicals.

 

7.3. Reassembling the Fleisch Flowhead

  1. Examine the fleisch element to ensure that no liquid or particles remain in the holes, grooves or pressure tappings.
  2. Check the 'O' rings for damage and ensure that they are correctly positioned within the grooves.
  3. Apply a very small amount of silicone grease to ‘O’ Rings and inside the surfaces of the flowhead body. Wipe off any visible amounts of grease. Ensure that the tiny annular holes on the outside of the fleisch element are not blocked.
  4. When re-assembling the flowhead, ensure that the blue pressure tapping is nearest to the largest diameter of the fleisch element.
  5. Ensure that the flowhead body is pushed fully home and rotate it so that the pressure ports are approximately 180? opposite the end of the fleisch element coil.
  6. Fit flow conditioning meshes to both the flowhead cone and the flowhead end cap.
  7. Push the flowhead end cap onto the larger diameter of the fleisch element and push the flowhead cone onto the smaller diameter.
  8. When attaching the flowhead connection tube ensure that the matching serrated edge pressure tappings on the flowhead and the Vitalograph Pneumotrac are connected to each other.
It is recommended that an accuracy check is carried out following reassembly to verify correct operation and accuracy.
