Abstract
The utility model provides an intelligent insulin pump drive mechanism, includes driving motor, universal coupling, feeds screw, straight line feed mechanism, and its characterized in that motor's output shaft is connected with the little internal diameter end of coupling body 1, and cylindric lock 2 radially fixes on the big internal diameter wall of coupling body 1, feeds screw 3 and passes the pore of slide 5, cooperates with cylindric lock 2 by the rectangle breach of its tip. The output power of the motor is transmitted to the feed screw through the universal coupling to drive the linear feed mechanism to do linear motion to push the syringe to supplement insulin to the human body. The mechanism of this design simple structure, stable performance are small, can satisfy the operation requirement of artificial intelligence type insulin pump completely.
Description
This utility model relates to medical apparatus and instruments, belongs to A61M 37/00 class, is used for the drive mechanism of intelligent insulin pump.
The drive motors power of artificial intelligence's type insulin pump is very little.When the drive motors axial line with when there is alignment error in merit axle axial line, can produce movement interference, motor can be stuck.In order to eliminate alignment error, need use star coupling.Yet, traditional star coupling structure relative complex, part is more, and it is very big to take up room, and is not suitable for miniature portable equipment such as artificial intelligence's type insulin pump.
The design's purpose provides a kind of drive mechanism of intelligent insulin pump, and is simple in structure, the stable performance volume is little, can satisfy the instructions for use of artificial intelligence's type insulin pump fully.
The drive mechanism of this intelligent insulin pump, comprise drive motors, star coupling, feeding screw, straight-line feed mechanism, the output shaft that it is characterized in that motor is connected with the little internal diameter end of shaft coupling body 1, straight pin 2 radially is fixed on the large diameter wall of shaft coupling body, feeding screw 3 passes the duct of slide 5, is cooperated with straight pin 2 by the rectangular indentation of its end.
Artificial intelligence's type insulin pump is a miniature portable unit, and inside comprises a drive mechanism.Require the drive mechanism volume little, structure must be simple, and performance must be reliable.The design's transmission principle is as follows: by the microcomputerized control drive motors, the outputting power of motor is passed to the feeding screw through star coupling, drives straight-line feed mechanism moving linearly and promotes syringe to the human body supplementation with insulin.

Accompanying drawings embodiment:
The drive mechanism of this artificial intelligence's type insulin pump, comprise micro-driving motor, star coupling, feeding screw, straight-line feed mechanism and baffle plate, the output shaft that it is characterized in that motor is connected with the little internal diameter end of shaft coupling body 1, straight pin 2 radially is fixed on the large diameter wall of shaft coupling body, feeding screw 3 passes the duct of slide 5, is cooperated with straight pin 2 by the rectangular indentation of its end.
Shaft coupling comprises shaft coupling body 1 and straight pin 2; Shaft coupling body 1 is a tubular member, its internal diameter one end is little, an end is big, little internal diameter end equates with the motor transmission shaft external diameter, the slightly larger in diameter of large diameter end is in feeding screw 3 external diameters, between shaft coupling and the feeding screw 3 radially with axially all leave suitable space, thereby but the feeding screw freely swings with respect to the electrical axis top to bottom, left and right, front and rear.The cylinder of feeding screw 3 one ends has axial rectangular indentation, and its width equals the external diameter of straight pin 2; Straight pin 2 two ends are embedded on the wall of shaft coupling body 1 large diameter one end.Rectangular indentation on straight pin and the feeding screw is for movingly, and the rotation of motor can accurately pass to the feeding screw; And this structure can be felt when deviation is arranged at electrical axis and feeding screw shaft, and the rotation of motor still can successfully pass to the feeding screw, and can not move interference.
Straight-line feed mechanism comprises slide 5, clasp nut 4 and the folding handle 6 of cuboid, and slide 5 has the duct of running through its long limit.Channel diameter equals the external diameter of feeding screw 3, and slide 5 broadsides one end is positioned at grooved hole on the duct, in spring is arranged.A side that is positioned at slide 5 flash is fixed with vertical with it push pedal 8, promotes the syringe supply side during work.The side of feed mechanism leans against on the appearance wall device of insulin pump.Prop up slide not deflection, rotation, guarantee its moving linearly.Clasp nut 4 is a right angle edge shape, is fixed on the slide 5 with straight pin at the fulcrum place, and be groove in its right angle end broadside, folding handle 6 is embedded in wherein, and makes opening and closing movement around alignment pin, and clasp nut 4 can be rotated around slide 5.When handle 6 was in " opening ", clasp nut and feeding screw were thrown off, but the feed mechanism reposition.The long limit end of clasp nut 4 props up spring, makes its following in working order and feed nut engagement.Be carved with screw thread in the clasp nut short end.
