Decontamination by Cleaning and Disinfection This is the recommended cleaning method where the user suspects that the flowhead interior may have become contaminated or if a user’s local requirements for handheld items includes disinfection.
Cleaning of Flowhead Interior 1. Disconnect the flowhead connection tubing from the flowhead and flowhead carrier. Disassemble the Fleisch flowhead:
1
Flowhead Complete
2
‘O’ Rings
3
Flowhead End Cap
4
Flow Conditioning Meshes
5
Flowhead Cone
6 7
Fleisch Element (containing coil/ capillaries) Flowhead Body
8
Port Pressure Tappings
Figure 2: Flowhead Assembly
2. Remove cone and end cap from flowhead. 3. Remove flow conditioning meshes from inside the cone and end cap. Examine for damage or contamination. If meshes are damaged or blocked, discard and replace with new parts.
4. Remove flowhead body from Fleisch element. To do this, place the Fleisch element on a hard, flat surface with the largest diameter at the top (this is the end with an ‘O’ ring showing). 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.
5. Cleaning. Swill Fleisch element vigorously in warm soapy water. Do not attempt to “rub” or “scrub” at the capillaries formed by the coil.
6. Wash the flowhead end cap, flowhead body, flow conditioning meshes and flowhead cone in warm soapy water. Rub surfaces to remove any visible soiling.
7. Ensure all parts are visibly clean. If not visibly clean repeat the cleaning process. 8. Rinse with potable tap water. If disinfection is required, proceed to disinfection steps after rinsing, otherwise proceed straight to drying.

Disinfection 1. Prepare disinfectant solution as per the disinfectant manufacturer’s recommendation. Always follow the safety guidelines given by the manufacturer of the disinfectant chemicals.
2. Disinfect Fleisch element, flowhead end cap, flowhead body, flow conditioning meshes and
flowhead cone by immersion in the solution. Ensure Fleisch element and flowhead body are immersed vertically and tap to remove air bubbles from interiors. Flush all surfaces to remove air bubbles. Soak parts for the time period recommended by the disinfectant manufacturer.
3. Rinse with potable tap water. Table 1: Recommended Disinfectants Disinfectant

Drying 1. Tap the Fleisch element gently several times with the capillaries formed by the coil orientated vertically to remove excess water.
2. Arrange disassembled parts separately so that any remaining water can drain and air can circulate, e.g. on a drying rack. Drying the Fleisch element may require leaving it in a warm place overnight. If available, a drying cabinet is ideal.
3. Leave to dry completely before reassembling.

Reassembly of Fleisch Flowhead 1. Examine Fleisch element and flowhead body to ensure that no liquid or particles remain in the holes or grooves.
2. Check ‘O’ rings for damage and ensure correct positioning 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. Refer to Figure 2: Flowhead Assembly to view placement of parts for reassembly. 5. Replace flowhead body onto Fleisch element. Ensure the pressure tapping on the flowhead body is nearest to the largest diameter (rear) of the Fleisch element.
Figure 3: Replacing the flowhead body onto the Fleisch element
6. Ensure that flowhead body is pushed fully home, and rotate it so that the port pressure tappings are approximately 180° opposite the end of the Fleisch element coil.

7. Fit flow conditioning meshes to both flowhead cone and flowhead end cap. 8. Push flowhead end cap onto the larger diameter of the Fleisch element and push flowhead cone onto the smaller diameter.
9. Reconnect flowhead tubing. Vitalograph recommends that calibration verification be carried out following reassembly to verify correct operation and accuracy.
