Abstract
The invention relates to a holding device for a syringe pump, the holding device being configured for holding the barrel of a syringe and comprising a rotatable holding member (11) which is rotatable from an open into a closed position, wherein the holding member (11) is configured in such a way that in the closed position the syringe barrel will be secured between a portion of the rotatable holding member (11) and a fixed section of the syringe pump. According to the invention, a damping device (2) configured to dampen the movement of the rotatable holding member (11) from the open into the closed position.
Claims19
A holding device for a syringe pump, the holding device being configured for holding the barrel of a syringe and comprising:
- a shaft having a longitudinal axis,
- a rotatable holding member which is connected to the shaft and rotatable about the longitudinal axis of the shaft relative to a fixed section of the syringe pump from an open position wherein the syringe barrel is not secured between a portion of the rotatable holding member and the fixed section of the syringe pump into a closed position wherein the syringe barrel is secured between the portion of the rotatable holding member and the fixed section of the syringe pump,
- a damping device configured to dampen a rotation of the rotatable holding member about the longitudinal axis from the open position into the closed position;
- and
- a spring configured to bias the holding member against the syringe barrel, wherein the spring is a coil spring surrounding the shaft connected to the rotatable holding member.
A holding device for a syringe pump, the holding device being configured for holding the barrel of a syringe and comprising:
- a shaft having a longitudinal axis,
- a rotatable holding member which is connected to the shaft and rotatable about the longitudinal axis of the shaft relative to a fixed section of the syringe pump from an open position wherein the syringe barrel is not secured between a portion of the rotatable holding member and the fixed section of the syringe pump into a closed position wherein the syringe barrel is secured between the portion of the rotatable holding member and the fixed section of the syringe pump, and
- a damping device configured to dampen a rotation of the rotatable holding member about the longitudinal axis from the open position into the closed position,
- wherein the damping device comprises a first and a second toothed element in engagement with one another, and
- wherein the second toothed element moves linearly when the holding member is rotated from the open position into the closed position.
A holding device for a syringe pump, the holding device being configured for holding the barrel of a syringe and comprising:
- a rotatable holding member which is rotatable relative to a fixed section of the syringe pump from an open position wherein the syringe barrel is not secured between a portion of the rotatable holding member and the fixed section of the syringe pump into a closed position wherein the syringe barrel is secured between the portion of the rotatable holding member and the fixed section of the syringe pump,
- a damping device configured to dampen the movement of the rotatable holding member from the open position into the closed position,
- the damping device comprising a first and a second toothed element in engagement with one another, the first toothed element being a gear wheel and the second toothed element being a gear rack, and the second toothed element moving linearly when the holding member is rotated from the open position into the closed position, and
- a shaft rotating along with the rotatable holding member and a cam element connected to the second toothed element, wherein the shaft engages the cam element in such a way that the cam element and thus the second toothed element is linearly moved when the rotatable holding member is rotated from the open position into the closed position.
