The present application relates generally to a drug transfer device and, more particularly, to a drug transfer device and system for transferring liquid medicament between containers.
Health care providers reconstituting, transporting, and administering hazardous drugs, such as cancer treatments, can put health care providers at risk of exposure to these medications and present a major hazard in the health care environment. For example, nurses treating cancer patients risk being exposed to chemotherapy drugs and their toxic effects. Unintentional chemotherapy exposure can affect the nervous system, impair the reproductive system, and bring an increased risk of developing blood cancers in the future. In order to reduce the risk of health care providers being exposed to toxic drugs, the closed transfer of these drugs becomes important.
Some drugs must be dissolved or diluted before they are administered, which involves transferring a solvent from one container to a sealed vial containing the drug in powder or liquid form, by means of a needle. Drugs may be inadvertently released into the atmosphere in gas form or by way of aerosolization, during the withdrawal of the needle from the vial and while the needle is inside the vial if any pressure differential between the interior of the vial and the surrounding atmosphere exists.
In one aspect, a drug transfer device includes a housing having a first end and a second end positioned opposite the first end, a vial attachment configured to secure the drug transfer device to a drug vial, a vial transfer member defining a passageway, with the vial transfer member configured to pierce a seal of a drug vial, a cannula received within the housing, with the cannula in fluid communication with the passageway of the vial transfer member and having a first end and a second end positioned opposite from the first end, a seal arrangement positioned within the housing, with the seal arrangement movable within the housing between a first position where the cannula is isolated from the first end of the housing and a second position where the cannula is configured to be in fluid communication with a mating connector received by the first end of the housing, and a connection member defining a passageway in fluid communication with the passageway of the vial transfer member, with the connection member configured to receive a mating connector.
The vial attachment may be secured to the second end of the housing. The second end of the cannula may be secured to the vial attachment, with the cannula extending from the vial attachment towards the first end of the housing with a first end of the cannula positioned intermediate the first and second ends of the housing. The connection member may extend from the vial attachment member. The passageway of the vial transfer member may include first and second passageways extending along a longitudinal direction of the vial transfer member, with the first passageway axially spaced from the second passageway and in fluid communication with the cannula and the second passageway in fluid communication with the passageway of the connection member. The seal arrangement may include a collet having a first end and a second end and a membrane received by the collet, with at least a portion of the collet received within the housing. The collet includes a body and a locking member connected to the body, with the collet is movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted. The connection member may include a membrane.
In a further aspect, a system for transferring a liquid medicament between containers includes a syringe adapter having a first end configured to be secured to a syringe barrel and a second end, an infusion adapter having a connection member and a container access member configured to be secured to an infusion container, and a drug transfer device. The drug transfer device including a housing having a first end configured to receive the connection member of the infusion adapter and a second end positioned opposite the first end, a vial attachment configured to secure the drug transfer device to a drug vial, a vial transfer member defining a passageway, with the vial transfer member configured to pierce a seal of a drug vial, a cannula received within the housing, with the cannula in fluid communication with the passageway of the vial transfer member and having a first end and a second end positioned opposite from the first end, a seal arrangement positioned within the housing, with the seal arrangement movable within the housing between a first position where the cannula is isolated from the first end of the housing and a second position where the cannula is configured to be in fluid communication with the infusion adapter when the infusion adapter is received by the first end of the housing, and a connection member defining a passageway in fluid communication with the passageway of the vial transfer member, with the connection member configured to receive the syringe adapter.
The system may include an air delivery pump in fluid communication with the first end of the syringe adapter. The system may include a drug measuring device and a controller in communication with the drug measuring device and the air delivery pump, with the controller configured to actuate the air delivery pump based on dosage information received from the drug measuring device. The air delivery pump may be in fluid communication with the first end of the syringe adapter via a delivery tube.
In a further aspect, a method for transferring liquid medicament between containers includes: securing a drug transfer device to a drug container comprising a liquid medicament; securing an infusion adapter to the drug transfer device; securing an infusion container to the infusion adapter; and introducing air into the drug container via the drug transfer device to transfer the liquid medicament from the drug container to the infusion container via the drug transfer device and the infusion adapter.
The method may further include inverting the drug container prior to introducing air into the drug container. The method may further include: securing a syringe adapter to the drug transfer device; securing a syringe barrel to the syringe adapter; and injecting air into the drug container via the syringe barrel, the syringe adapter, and the drug transfer device to introduce the air into the drug container. The air may be introduced into the drug container via the drug transfer device via an air delivery pump. The method may include securing a delivery tube to the drug transfer device, with the delivery tube extending between the drug transfer device and the air delivery pump. The method may include: sending dosage information to a controller in communication with the air delivery pump; and actuating the air delivery pump based on the dosage information. The method may include measuring a volume and/or a weight of the infusion container via a drug measuring device, with the drug measuring device sending one or more of a volume measurement, weight measurement, and the dosage information to the controller; and actuating the air delivery pump via the controller until the infusion container receives a prescribed dosage of the liquid medicament.
