Background Information Or Related Documents:
Graseby Syringe Drivers (MS16A & MS26) Document

The limitations of the Graseby syringe drivers MS16A and MS26 are well known and well documented in the literature. The IMB has received a number of recent incident reports from the Irish market and wishes to remind users to use these devices with caution. 

The IMB also wishes to raise awareness of the discontinuation of Graseby syringe drivers MS16A and MS26 from July 2014.

Actions To Be Taken:
The IMB advises users: 

(1) Graseby syringe drivers MS16A and MS26 should be used with caution. The IMB wishes to remind users of the following:- 

a. These devices do not use standard measuring units. The MS16A is calibrated in milimeters (mm) per hour and the MS26 is calibrated in mm per 24 hour 
b. The two models MS16A and MS26 are visually similar and care is needed to ensure the correct infusion rate is set 
c. These devices lack a stop button. The devices can only be stopped by moving the rate switch to 00 or taking out the battery 
d. The rate can be changed while the devices are in operation 
e. There is no protection against misconnection of the syringe, air entrapment or siphoning. To help prevent tampering of the syringe or the syringe driver, lock boxes are available for use with these devices 
f. The occlusion response characteristics of the device are very poor 
g. The device does not retain a record of operation and cannot be interrogated 
h. A ‘prime’ button provides maximum infusion rate when depressed. There is no limitation on the number of times this may be activated nor a record of activation 

(2) Ensure that devices are repaired and maintained appropriately. The manufacturer advises that these devices have a minimum life expectancy of 5 years from date of sale. This is dependant upon the devices being serviced and maintained in accordance with the recommended instructions defined within the Instruction Manuals provided with the device. Failure to maintain the product regularly and effectively can shorten the lifetime of the device and in some instances can result in premature failure of the device. The warranty on these devices is 1 year. 

(3) Due to the discontinuation of these devices from July 2014, the IMB wishes to remind those users who seek an alternative device to consider the following safety features when purchasing syringe drivers:- 
a. Rate settings in millilitres (ml) per hour 
b. Mechanisms to stop infusion if the syringe is not properly and securely fitted 
c. Alarms that activate if the syringe is removed before the infusion is stopped 
d. Lock-box covers and/or lock out controlled by password 
e. Provision of internal log memory to record all pump events 
Note: This is not an exhaustive list.
