A flexible or rigid tube intended to be used during an open surgical procedure for the administration of a haematological concentrate and/or haemostatic agent (e.g., thrombin, platelet concentrate, polysaccharide) to a bleeding surgical site, typically to facilitate haemostasis and healing, in conjunction with an applicator such as a syringe/plunger [not included]. It may have a single channel, to administer one product, or dual channels for co-administration of two different agents simultaneously; a channel for connection to a gas pump for spraying may also be incorporated. This is a single-use device.
