An apparatus comprising: a pump side member comprising: a pump side member housing have a first end and a second end; and a first channel disposed within the pump side member housing; an inlet disposed at the first end of the pump side member housing and in fluid communication with the first channel; a first valve disposed within the first channel downstream from the inlet; and a securing bar coupled to the second end of the pump side member housing; a patient side member comprising: a patient side member housing having a proximate end and a distal end; a second channel disposed within the patient side member housing; an outlet disposed at the distal end of the patient side member housing and in fluid communication with the second channel; a second valve disposed within the second channel upstream from the outlet; and a securing arm coupled to a proximate end of the pump side member housing; wherein the pump side member is configured to detachably couple to the patient side member via the securing bar and the securing arm; and wherein the securing bar is configured to bias the securing arm radially inward when the pump side member is decoupling from the patient side member, characterised in that: the apparatus further comprises a securing arm guard extending from the patient side member and positioned radially outward from the securing arm, wherein the securing arm guard defines a key hole configured to permit access to the securing arm, wherein the securing arm is positioned on the pump side member such that when the patient side member and the pump side member are decoupled and inwardly opposing axial forces are applied to the patient side member and the pump side member, a distal end of the securing arm interferes with a distal portion of the securing bar preventing the patient side member and the pump side member from detachably coupling. a pump side member comprising: a pump side member housing have a first end and a second end; and a first channel disposed within the pump side member housing; an inlet disposed at the first end of the pump side member housing and in fluid communication with the first channel; a first valve disposed within the first channel downstream from the inlet; and a securing bar coupled to the second end of the pump side member housing; a pump side member housing have a first end and a second end; and a first channel disposed within the pump side member housing; an inlet disposed at the first end of the pump side member housing and in fluid communication with the first channel; a first valve disposed within the first channel downstream from the inlet; and a securing bar coupled to the second end of the pump side member housing; a patient side member comprising: a patient side member housing having a proximate end and a distal end; a second channel disposed within the patient side member housing; an outlet disposed at the distal end of the patient side member housing and in fluid communication with the second channel; a second valve disposed within the second channel upstream from the outlet; and a securing arm coupled to a proximate end of the pump side member housing; a patient side member housing having a proximate end and a distal end; a second channel disposed within the patient side member housing; an outlet disposed at the distal end of the patient side member housing and in fluid communication with the second channel; a second valve disposed within the second channel upstream from the outlet; and a securing arm coupled to a proximate end of the pump side member housing; wherein the pump side member is configured to detachably couple to the patient side member via the securing bar and the securing arm; and wherein the securing bar is configured to bias the securing arm radially inward when the pump side member is decoupling from the patient side member, characterised in that: the apparatus further comprises a securing arm guard extending from the patient side member and positioned radially outward from the securing arm, wherein the securing arm guard defines a key hole configured to permit access to the securing arm, wherein the securing arm is positioned on the pump side member such that when the patient side member and the pump side member are decoupled and inwardly opposing axial forces are applied to the patient side member and the pump side member, a distal end of the securing arm interferes with a distal portion of the securing bar preventing the patient side member and the pump side member from detachably coupling.
