Syringe pump
First Claim
1. A syringe pump, comprising:
- a flange attaching section having a flange supporting section and a movable section, the flange supporting section for contacting a flange section of a barrel of a syringe so as to support the flange section, the movable section being adjustable around a rotational axis extending generally parallel to the flange supporting section, whereby the flange section of the syringe barrel is locatable between the flange supporting section and the movable section; and
a flange attaching operation section for causing rotation of the movable section.

Abstract
A flange attaching section has a flange supporting section and a movable section, and the movable section can approach the flange supporting section and separate therefrom due to rotational moving. Even if a flange section of a barrel of a syringe has various thickness, the flange section is easily attached between the flange supporting section and the movable section, and although the attachment is easy, the flange section comes in pressure contact with the flange supporting section in the attached state. Even if, therefore, the flange section of the barrel of the syringe has various thickness, a syringe pump, in which moving of the barrel of the syringe during infusion is prevented securely and the infusion is executed at an accurate speed, is provided.

3. A syringe pump, comprising:
-
a flange attaching section having a flange supporting section and movable section, the flange supporting section being brought into pressure contact with a flange section of a barrel of a syringe so as to support the flange section, the movable section being capable of approaching the flange supporting section and separating therefrom due to rotational moving, the flange section being attached between the flange supporting section and the movable section; a barrel attaching section having a barrel supporting section and a barrel pressing section, the barrel supporting section being brought into pressure contact with the barrel so as to support the barrel, the barrel pressing section pressing the barrel against the barrel supporting section and releasing the pressing; and a differential section for instructing the barrel pressing section to execute the pressing after the approaching of the movable section is ended.
