Apparatus for preparing a fluid for a medical procedure

An opener for opening the membrane of a vessel which contains at least one medicament in the form of powder and defines a bottom, a side wall, and a top opening which is closed by an membrane for sealing the inside of the vessel after the vessel receives a predetermined amount of the medicament, the opener comprising:

• a holder for vertically holding the vessel to downwardly orient the opening;
• a cutter, provided beneath the opening of the vessel held by the holder, for partially cutting the membrane along the periphery of the opening;
• a mechanism for vertically moving the holder toward the cutter so that the cutting edge of the cutter pierces and partially separates the membrane from the periphery of the opening whereby the medicament in the vessel falls from the vessel;
• a receiving member, in the form of a mesh provided beneath the cutter, for receiving all amount of the medicament from the vessel;
• and
• a nozzle for directing water in the form of a spray to the medicament received by the receiver member to dissolve the medicament into the water directed to the medicament.

An apparatus for preparing a fluid for a medical procedure by mixing of first and second medicaments with water, the first and second medicaments being held in first and second vessels each of which defines a bottom, a side wall, and a top opening which is closed by an membrane for sealing the inside of the vessel;

• the apparatus comprising:
• a source of water;
• a first opener for opening the membrane of the first vessel, the first opener including a holder for vertically holding the first vessel to downwardly orient the opening;
• a cutter, provided beneath the opening of the first vessel held by the holder, for partially cutting the membrane along the periphery of the opening;
• a mechanism for vertically moving the holder toward the cutter so that the cutting edge of the cutter pierces and partially separates the membrane from the periphery of the opening whereby the medicament in the vessel falls from the vessel;
• a receiving member, in the form of a mesh provided beneath the cutter, for receiving all amount of the medicament from the first vessel;
• and
• a nozzle for directing water from the source of water in the form of a spray to the first medicament received by the receiving member to dissolve the first medicament into the water directed to the medicament;
• a second opener for opening the membrane of the second vessel, the first opener including a holder for vertically holding the second vessel to downwardly orient the opening;
• a cutter, provided beneath the opening of the second vessel held by the holder, for partially cutting the membrane along the periphery of the opening;
• a mechanism for vertically moving the holder toward the cutter so that the cutting edge of the cutter pierces and partially separates the membrane from the periphery of the opening whereby the second medicament in the vessel falls from the vessel;
• and
• a nozzle for directing water from the source of water in the form of a spray to the inside of the second vessel;
• and
• a tank for receiving and containing the substances dissolved into the sprayed water.
