Graseby MS 16A and MS 26 Syringe Drivers Instruction Manual
What is a Syringe Driver? A Syringe Driver is a power driven device for pushing the plunger of a syringe forward at an accurately controlled rate. It is an aid in administering medicinal preparations in liquid form over much longer periods than could be achieved by injecting by hand. A suitable sterile syringe with a sterile pathway is also required to deliver medication to the patient. The Graseby MS 16A and MS 26 Syringe Drivers are both non-sterile devices. They are battery powered ambulatory devices, that can be carried by patients whilst undergoing treatment. The Syringe Drivers are suitable for administering medication intravenously (IV) or subcutaneously. For more information on subcutaneous infusion therapy, see the section Guide to subcutaneous analgesia. A driver may be reused if it is in good condition and has been regularly tested and maintained.
What are the differences between the Graseby MS 16A and MS 26 Syringe Drivers? It is most important to be familiar with what the differences are. The most visible difference is the colour; the MS 16A has a blue label and the MS 26 a green one. The table shows all the main differences: Feature Rate range Indicator lamp flashes every Motor turns every Test time

Graseby MS 16A and MS 26 Syringe Drivers Instruction Manual
Why are there two models? The MS 16A is intended for administrations lasting between 30 minutes and 24 hours. The rate setting is in millimetres (mm) of syringe plunger movement every hour. The MS 16A is known as the HOURLY RATE Syringe Driver. For slower infusions, the MS 26 is intended for administrations over periods of 1 day and longer. The rate setting is in millimetres (mm) of syringe plunger movement every 24 hours. The MS 26 is known as the DAILY RATE Syringe Driver. At the slowest setting, of 01, the MS 26 would take 60 days to move the actuator over the full length of travel. The MS 26 can also be used to give manually administered boost doses during the administration.
How to use the Syringe Driver Do’s and Don’ts DO
check the battery daily.
DO
avoid using mobile telephones close, nearer than 1 metre, to the Syringe Driver. Although there have been no confirmed reports of mobile telephones interfering with the operation of the Syringe Driver, following this advice will help reduce any risk.
DON’T
use the Syringe Driver without understanding these instructions.
DON’T
get it wet. It is not waterproof, even when enclosed in a Lockbox, and the performance will be affected.
DON’T
take it from a cool environment and put it into a warm, very humid environment (e.g. an incubator) or take it from there into a cooler one. Condensation will form and the inside will get wet.

Fitting the battery Always fit a 9 volt (9 V) ‘alkaline’ battery. Alkaline batteries can be identified by the international code 6LR61 marked on them or on their packaging. They are available from most retail outlets selling batteries. A recommended battery of this type is the DURACELL MN1604. Be careful when selecting a battery as some brands may not fit properly. If possible, try the battery in the battery compartment first. Never try to force in a battery which is too large as this may damage the battery contacts. Batteries of the ‘zinc-carbon’ type (marked 6F22 or 6R61), for example a PP3, are not recommended. They perform poorly with the Syringe Driver and need to be replaced more often. To fit a battery: Slide off the cover at the back of the Syringe Driver.
2.
Push in the battery. The label in the battery compartment shows which way round to put it. Accidentally putting it in the wrong way round will not do any harm.
3.
Slide the cover on again until it latches shut.

Setting the correct rate for the Graseby MS 16A 1.
Fill the syringe with the required volume of medication.
2.
Connect and fill the infusion line. Make sure the connection is secure and the air is expelled.
3.
Measure the distance, in millimetres (mm), from the empty (0) line on the syringe’s scale up to the line where the plunger piston is. There is a ‘mm’ scale on the front of the MS 16A for this.
4.
Divide this distance, measured in mm, by the time in hours (h) all the medication in the syringe needs to be administered in. The answer is the rate to set in the rate windows

Here is an example: A syringe is to be used to administer 8 ml of medication over 12 hours. With this syringe filled to the 8 ml line, the plunger travel measures 48 mm.
48 mm ÷ 12 hours = 4 mm per 1 h
Set the rate switches to 04
Each switch must be moved until all of the number can be seen in the window. In this example, every hour the syringe plunger will move forwards 4 mm, administering about 0.67 ml of the medication and after 12 hours the syringe will have emptied. Remember that for rates up to 9 the left-hand ‘tens’ number must be set at 0. If the result of the division is not a whole number select the nearest whole number for the rate. REMEMBER THAT YOU HAVE TO SET THE RATE IN MILLIMETRES (mm) NOT MILLILITRES (ml).

Graseby MS 16A and MS 26 Syringe Drivers Instruction Manual
Notes on setting up your Syringe Driver An alternative method may be used to set up the Graseby MS 16A or MS 26 Syringe Driver if a specific policy has been devised as part of your hospital/ community protocol. The alternative method involves first measuring the volume in the syringe, then priming the line. Precaution: If you measure first, then prime the line, the infusion will finish early. You should therefore only use this method when your hospital has devised this protocol for a specific clinical area.
Fitting the syringe 1.
Put the syringe on top of the Syringe Driver, with its barrel in the shallow V-shaped recess. The finger grip on the syringe barrel must be in the slot in the case.
2.
Move the actuator up to the syringe plunger, by pressing and holding in the button on the side, and sliding it along. The push-button on the plunger of the syringe must be fitted in the slot in the actuator. Be careful not to push the plungers.
3.
GM0309-A
Older versions did not have the slot in the actuator for the syringe plunger push-button. A small metal screw-clamp was supplied and this must be fitted through the hole in the actuator and used to hold the plunger push-button. The actuator can be replaced by the latest type and it is recommended that this is done the next time the Syringe Driver is overhauled. 4.
Put the rubber securing strap over the syringe barrel and pull it tight. Hook and then press it into the groove in the side of the case.
Precaution: Risk of uncontrolled flow into the patient. Only use the Driver if the syringe can be secured as described. If the selected syringe does not fit, try another brand of syringe with the same capacity. Precaution: The rate setting used may need to be changed so the dose is administered in the same time. Recalculate the correct rate to use.
