Infusion pump with pivotable peristaltic pump unit
A linear peristaltic infusion pump has a pump housing to which a front lid is pivotably hinged to open and close the front lid. A peristaltic pump unit is pivotably received in the pump housing. A pivoting mechanism is functionally connected to the front lid to pivot the peristaltic pump unit backward into the pump housing when the front lid is open, and to pivot the peristaltic pump unit forward and away from the pump housing when the front lid is closed.
1 . An infusion pump comprising:
a pump housing extending from a front end to a back end;
a front lid pivotably hinged to the front end of the pump housing in order to open and close the front end of the pump housing;
a peristaltic pump unit pivotably received in the pump housing; and
a pivoting mechanism connected to the front lid,
the peristaltic pump unit being a linear peristaltic pump,
the pivoting mechanism being configured to pivot the peristaltic pump unit backward towards the back end of the pump housing when the front lid is opened, and
the pivoting mechanism being configured to allow the peristaltic pump unit to pivot forward towards the front end of the pump housing when the front lid is closed.
2 . The infusion pump according to claim 1 , wherein the peristaltic pump unit is arranged in a peristaltic frame arranged stationarily in the pump housing so as to be pivotably arranged relative to the pump housing.
3 . The infusion pump according to claim 1 , further comprising an adjustable spring element that presses the peristaltic pump unit forward towards the front end of the pump housing when the front lid is closed.
4 . The infusion pump according to claim 3 , wherein the adjustable spring element is a wave spring.
5 . The infusion pump according to claim 3 , wherein a spring force of the adjustable spring element is adjustable via an adjustment device.
6 . The infusion pump according to claim 5 , wherein the adjustment device is a screw.
7 . The infusion pump according to claim 1 , wherein the pivoting mechanism has a deadbolt which moves in a longitudinal direction of the front lid to lock and unlock the front lid.
8 . The infusion pump according to claim 7 , wherein the deadbolt has at least one guide groove in which a closing pin of the front lid engages when the front lid is closing.
9 . The infusion pump according to claim 7 , wherein the peristaltic pump unit has a first wedge portion on which a second wedge portion of the deadbolt slides when the front lid is closing.
10 . The infusion pump according to claim 9 , wherein a first wedge tip of the first wedge portion presses on a second wedge tip of the second wedge portion when the front lid is open.
11 . The infusion pump according to claim 9 , wherein the deadbolt has a reset element that is L-shaped, the reset element comprising the second wedge portion.
12 . The infusion pump according to claim 11 , wherein the reset element is an injection-molded plastic part and the second wedge portion has a reinforcing structure made of metal.
13 . The infusion pump according to claim 1 , wherein the peristaltic pump unit comprises a drive motor, and the pivoting mechanism is configured to pivot the peristaltic pump unit including the drive motor backward towards the back end of the pump housing when the front lid is opened.
14 . An infusion pump comprising:
a pump housing extending from a front end to a back end;
a front lid pivotably hinged to the front end of the pump housing in order to open and close the front end of the pump housing;
a peristaltic pump unit pivotably received in the pump housing; and
a pivoting mechanism connected to the front lid,
the peristaltic pump unit being a linear peristaltic pump,
the pivoting mechanism being configured to pivot the peristaltic pump unit backward towards the back end of the pump housing when the front lid is opened, and
the pivoting mechanism being configured to allow the peristaltic pump unit to pivot forward towards the front end of the pump housing when the front lid is closed,
wherein the pivoting mechanism has a deadbolt which moves in a longitudinal direction of the front lid to lock and unlock the front lid.
15 . The infusion pump according to claim 14 , wherein the deadbolt has at least one guide groove in which a closing pin of the front lid engages when the front lid is closing.
16 . The infusion pump according to claim 14 , wherein the peristaltic pump unit has a first wedge portion on which a second wedge portion of the deadbolt slides when the front lid is closing.
17 . The infusion pump according to claim 16 , wherein a first wedge tip of the first wedge portion presses on a second wedge tip of the second wedge portion when the front lid is open.
18 . The infusion pump according to claim 16 , wherein the deadbolt has a reset element that is L-shaped, the reset element comprising the second wedge portion.
19 . The infusion pump according to claim 18 , wherein the reset element is an injection-molded plastic part and the second wedge portion has a reinforcing structure made of metal.
