Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present embodiment provides an infusion pump with an adjustable transmission part position, which comprises a housing 1, an injection pump 2 and an infusion pump 3 which are erected in the housing 1, and a driving mechanism 4 arranged between the injection pump 2 and the infusion pump 3; the driving mechanism 4 comprises a motor 41, a driving part fastened with a driving shaft of the motor 41, and a transmission part capable of being overturned around the driving part, wherein an injection pump driving part is arranged at the end part of the injection pump 2, and an infusion pump driving part is arranged at the end part of the infusion pump 3; when the injection pump 2 works, the transmission part is turned over between the driving part and the injection pump driving part and is connected with the driving part and the injection pump driving part; when the infusion pump 3 works, the transmission part is turned over between the driving part and the infusion pump driving part and is connected with the driving part and the infusion pump driving part.
Specifically, in this embodiment, the driving portion is configured as a driving gear 42 coaxially fastened to the driving shaft of the motor 41, the transmission portion includes an overturning arm pivotally connected to the driving shaft of the motor 41, a driven gear 44 pivotally connected to an end of the overturning arm away from the driving shaft of the motor 41, and a handle 5 extending from the housing 1 for driving the overturning arm to rotate around the driving shaft of the motor 41, and the driving gear 42 is meshed with the driven gear 44. The syringe pump driving part is a syringe pump gear set 21 arranged at one end of a driving shaft of the syringe pump 2; the infusion pump driving part is an infusion pump gear set 31 arranged at one end of a driving shaft of the infusion pump 3.
By adopting the above structural design, when power switching is required to be realized between the infusion pump 3 and the injection pump 2, the turning arm can be driven to rotate around the driving shaft of the motor 41 through the rotation of the handle 5, and then the driven gear 44 arranged at the end part of the turning arm is driven to rotate along the peripheral surface of the driving gear 42 and then meshed with the infusion pump gear set 31 or the injection pump gear set 21 at one side of the driving gear 42, so that the power switching is realized conveniently and rapidly.
