II Description Medela‘s phototherapy lamp is a high quality product developed for the treatment of neonatal hyperbilirubinaemia. It meets the highest demands in making optimum use of the effective light spectrum and in energy savings. As a result of using energy saving fluorescent tubing, heat development has been considerably reduced in comparison with conventional equipment. Operating costs are therefore lower and there are no effects on surroundings (e.g. temperature control of infant incubators). This modern concept offers many advantages both for successful therapy as well as for nursing staff.

III Applications Indications: Medela‘s phototherapy lamp is intended for the efficient and safe treatment of excessive serum bilirubin concentrations in new-born babies. Contraindications: A rapidly increasing bilirubin value may require a more intensive therapy. In these cases, several Medela phototherapy lamps can be used simultaneously. Specially designed for this purpose, the wheeled stand enables the lamps to be positioned next to each other. The phototherapy lamp must be used outside of an incubator or with a warming bed. If these are not necessary, we recommend using a BiliBed for the therapy. When used with an incubator there must be enough room between the devices to ensure proper ventilation, in order to prevent an accumulation of oxygen. The phototherapy lamp is not admitted for use: • in hazardous locations • in areas which may be enriched with oxygen N.B. The use of these lamps for anything but their intended purpose can be hazardous. Portable and mobile RF communication devices may influence the device.

IV Equipment The lamp body contains four compact fluorescent tubes. According to requirements, blue light or white light can be selected or combined. This permits effective treatment in line with requirements. The special tubes which emit blue light in the visible range (425 – 475 nm) are the most suitable for phototherapy. The tubes that emit white light can also be used. This light has a lower therapeutic effect, but is preferred when good light is needed for examination purposes. Any combination of blue and white light is, of course, possible. The fluorescent tubes can be switched on and off in pairs. The light in the tubes effective for therapy is electronically monitored. If the fluorescent tubes need changing an LED warning lamp lights up on the lamp body. The lamp body is equipped with a specially mirrored screen that directs light onto the child and limits light spread. This improves the therapeutic effect and protects surroundings from disturbing blue light. The lamp housing can be infinitely adjusted for height as well as forward and back positions. In addition, it can be rotated up to 90° on both sides for sideways irradiation. The mobile stand is equipped with antistatic rollers two of which are fitted with brakes. The ballast units are located in the metal foot, which lowers the centre of gravity for good stability.

V Assembly 5.1 Assembling the stands • As shown in the illustration, stand the mobile base upright. • Place the column onto the mobile base and fasten it with 4 screws.

Fig. 1

5.2 Installing the fluorescent tubes 3

a) Remove the lamp grille • Unscrew the bayonet screw (90° turn) (Fig. 2a). • Insert a screwdriver on one side of the lamp body alternatively in the two openings and press lightly outwards until the grille springs out of its hol der (Fig. 2b, c).

Fig. 2

b) Insertion of the fluorescent tubes The lamp body can hold four compact fluorescent tubes. Special tubes can be used which emit light mainly in the 425 – 475m range and are therefore highly suitable for phototherapy. As stray light is limited, blue light can be used exclusively to provide the greatest therapeutic effect. Tubes with white light can also be used according to requirements.

Fig. 3

• Insert the fluorescent tubes into the retainer; then push the fluorescent tube into its socket (Fig. 3). • Insert the remaining three tubes in the same way. N.B. With mixed lighting, the blue tubes must always be installed in the outer two positions to enable troublefree functioning of the tube warning display for changing the tubes.

c) Replace the lamp grille 1) Lamp grille 2) Lamp body 3) Opening 4) Retainer 5) Fluorescent tubes

• On the inside of the lamp body there are protruding support ribs. Place the grille on these ribs and press until it clicks in at all four corners. • Tighten the bayonet screw (90° turn).

V Assembly 5.3 Different positios

• By turning the two handles illustrated, the clamps can be released or tightened. The lamp can thus be raised or lowered (Fig. 4) or moved forward or back (Fig. 5). • In addition, for side irradiation, the lamp can be turned up to 90° in both directions.

Distance from the baby • The distance should be kept as small as possible (i.e. approx. 25 cm) for maximum therapeutic effect. When used with an incubator the distance between lamp and upper edge of the incubator must be at least 3 cm. When used with an incubator there must be enough room between the devices to ensure proper ventilation, in order to prevent an accumulation of oxygen.

Fig. 4

The treatment is most effective when only blue light fluorescent tubes are used (Type Osram Dulux L18W/71 or Ralutec long 18W/71). The efficiency and safety can only be guaranteed when the fluorescent tubes from Medela are used. • If the distance cannot be kept small (e.g. with some incubators) and the maximum effect is necessary, additional lamps can be used in order to irradiate the baby from above and from the side.

5.4 Rollers / Breaks 2

VI Irridiation levels According to the study from M. Jeffrey Maisels (Pediatrics Vol. 98, No. 2, August 1996: Why use Homeopathic Doses of Phototherapy) the efficacy of phototherapy depends on three factors: • Spectrum of light delivered by the phototherapy unit. Because of the optical properties of bilirubin and skin, the most effective wavelengths are in the blue-green spectrum. • Power output of the light. This also depends on the distance of the light from the infant. The lower the distance, the higher the efficacy. • Surface area of the infant exposed to phototherapy. The efficacy is higher when more skin is subjected to phototherapy.

If necessary, roll down the top of the diaper below baby‘s naval, so that the maximum amount of bare skin will be exposed to the therapeutic light.

VII Commissioning the phototherapy lamp

Fig. 6 All four tubes switched off

Fig. 7 Both inner tubes switched on

Fig. 8 Both outer tubes switched on

Fig. 9 All four tubes switched on

• Connect the cable to the power supply, ensuring in advance that the voltage matches the details given on the specification plate. • Adjust lamp for position and height. • Ensure that the height adjustment is securely tightened. Then push the phototherapy lamp into place. • Switch on the phototherapy lamp with the on/off switches on the lamp body. The illustrations Fig. 6 – 9 show the different alternatives.

Fig. 10 LED Display

VIII LED display When the lamp is switched on, the electronic monitoring of the blue, i.e. the therapeutic, light of the fluorescent tubes is activated. If this proportion of the light sinks to approx. 75%, an optical warning light lights up (Fig. 10). If the optical warning stays on continuously, all the blue tubes need changing. If the display lights up when the phototherapy light is switched on and goes out after a short time (max. 45 minutes), this is of no importance. The tubes only need changing when the display is on continuously. The white light tubes are not monitored, since their proportion of blue light is minimal. They are only replaced when they are no longer on. If the white tubes are installed in the outer position, the LED display is on continuously. For this reason, it is vital to always install the blue light tubes in the outer positions.

IX Therapy Warning If the phototherapy lamp is positioned too close to an external source of heat (e.g. heat lamp), the phototherapy lamp could be damaged. For this reason sufficient distance must always be maintained between the equipment. • Ensure that the height adjustment and lamp position are securely tightened. • Place as close to the infant as possible (approx. 25 cm). • Protect the eyes of the child since blue light can cause undesired side effects. If necessary, a barrier should be set up to protect the patients adjacent to the phototherapy equipment. A small percentage of the population is sensitive to blue light from any phototherapy device. We recommend that nursing staff should be informed about the possible side effects (fatigue, headache) and should (if blue-light sensitive) avoid being in the area for prolonged amounts of time. Should this be unavoidable, wearing yellow-tinted glasses can reduce the effects of blue light irradiation. • Check whether the lamp composition, resp. the choice of tubes corresponds to the treatment required. Blue light and white light can be mixed at will, whereby white light is generally less irritating and is more pleasant for the examination of the baby. • Before each use: Check LED warning light – if it lights up, all fluorescent tubes must be replaced. Phototherapy and the use of reflective foils may cause hazardous body temperatures. It is imperative to check the baby‘s temperature regularly. When used with an incubator, check the necessity to regulate the air temperature and set the incubator on skin-controlled mode. • Monitor the infant during therapy – Check the bilirubin levels regularly. Photoisomeres of bilirubin may cause toxic effects. – Make sure the infant is lying in the center of the light. – Phototherapy influences the infant‘s water balance. In order to prevent dehydration, it may be necessary to feed the baby more often. Attention Auxiliary devices which are used in the same area as the phototherapy lamp must comply with the general requirements for safety according to IEC 60601-1. Drugs and infusion liquids shall not be stored in the radiation area.

X Maintenance Warning Disconnect power supply before performing maintenance jobs! 1

10.1 Replacing the starter • A faulty starter either causes the fluorescent tubes to flicker for an excessive period of time when switched on or fails to trigger the tubes. • Switch off the unit and disconnect the power cable from its socket. • Remove the lamp grille. Unscrew the bayonet screw (90° turn) (Fig. 11). Insert a screwdriver on one side of the lamp body alternatively in the two openings and press lightly outwards until the grille springs out of its holder. • The four starters are now visible (Fig. 12). The two inner and two outer fluorescent tubes and starters are connected in pairs. It is therefore recommended that the two starters that belong together are always replaced at the same time. • Turn the starter anti clockwise (approx. a quarter turn) and remove. • Insert new starter (do not use an electronic type!) and turn it clockwise as far as possible. • Replace the lamp grille: On the inside of the lamp body there are protruding support ribs. Place the grille on these ribs and press until it clicks in at all four corners. Tighten the bayonet screw (90° turn).

• If the proportion of therapeutic light sinks below the minimum level, an optical display will light up when the lamp is switched on. This means that all the blue light lamps need replacing. • Switch off the phototherapy lamp and disconnect from power supply. • Remove the lamp grille. Unscrew the bayonet screw (90° turn) (Fig. 11). Insert a screwdriver on one side of the lamp body alternatively in the two openings and press lightly outwards until the grille springs out of its holder. • Release the fluorescent tubes from the clips and carefully remove them from the sockets (Fig. 12). • Put these tubes aside immediately in order to avoid confusion. • Insert new tubes into the clips and push into the sockets (Fig. 13). • Check whether the lamp grille reflectors are clean and shiny; clean if necessary. • Replace the lamp grille: On the inside of the lamp body there are protruding support ribs. Place the grille on these ribs and press until it clicks in at all four corners. Tighten the bayonet screw (90° turn).

X Maintenance 10.3 Testing the LED-warning light The functioning of the LED-warning light which monitors the light intensity, can be tested as follows:

Fig. 14

• Turn the lamp body so that the fluorescent tubes are facing up. • Remove the lamp grille (as shown under 10.1). • Turn on the outer fluorescent tubes The inner tubes must be turned off for this test, as they could falsify results. • Make sure that the lamp is not in direct sunlight • Place your finger between the fluorescent tube and the lamp housing. The distance to the sensor should be approximately 10 cm. • Slowly move your finger closer to the sensor and monitor the LED (Figure 14) • The LED should not light up in the beginning. When your finger gets closer to the sensor, the LED will light up. Shortly before your finger reaches the sensor, the LED should extinguish. • After completing the test, remount the lamp grille.

10.4 Cleaning and disinfecting The outside surfaces of the phototherapy lamp can be cleaned with a damp cloth. Cleaning or disinfecting agents should not be used in concentrated form! Flammable solutions may not be used for cleaning the phototherapy lamp. Aggressive cleaning agents may damage the plastic housing and cause cracks. If this occurs, the lamp head must be replaced out of safety reasons!

XI Disposal The Phototherapy Lamp is of modular design. It can thus be disassembled into its individual components. The Phototherapy Lamp is mainly made of technical plastics which can be disposed of in accordance with local regulations. The lamp and electric parts should be disposed of separately.
