Drug mixing device

Abstract

This invention provides a drug mixing device comprising a base and a base module formed by an assembly unit disposed on the base in different directions; a drive module disposed on the assembly unit and having a motor unit and a transmission unit connected to the drive, the other end of the transmission unit having at least one limiting hole; a counterweight module comprising a first counterweight unit and at least one counterweight connecting rod, one end of the counterweight connecting rod passing through the corresponding limiting holes to assemble the first counterweight unit; a crank unit connected to the counterweight connecting rod at one end; a mixing module disposed on the other end of the crank unit and comprising a support unit and a clamping unit, one end of the support unit connected to the crank unit and the other end connected to the clamping unit; and a guide module disposed on the mixing module at one end and on the assembly unit at the other end; wherein, the motor unit rotates the transmission unit and drives the crank unit to move the connected guide module up and down along the second direction to improve drug uniformity and administration safety.

Claims

1. A drug mixing device, mainly comprising: a base module, including a base disposed along a first direction and an assembly unit disposed from one end of the base along a second direction; a drive module, disposed on the assembly unit and including a motor unit and a transmission unit, the motor unit driving the connected transmission unit to rotate, and the transmission unit having at least one limiting hole at its other end connected to the motor unit; a counterweight module, including a first counterweight unit and at least one counterweight connecting rod, one end of the counterweight connecting rod passing through corresponding limiting holes, and the other end being fitted with the first counterweight unit; a crank unit, one end of which is connected to at least one of the counterweight connecting rods; and a mixing module, disposed at the other end of the crank unit, and the mixing module including a support unit and a clamping unit, wherein... The support unit is connected to the crank unit at one end and to the clamping unit at the other end; and a guide module is assembled at one end to the hybrid module and at the other end to the assembly unit; wherein, the motor unit rotates the transmission unit, causing the first counterweight unit to rotate around the transmission unit as the axis, and drives the crank unit to move the guide module connected to the hybrid module up and down along the second direction.

2. The drug mixing apparatus as claimed in claim 1, further comprising a first counterweight unit and a second counterweight unit arranged along the first direction, the transmission unit causing the second counterweight unit to rotate around its circumference.

3. The drug mixing device as described in claim 2, further wherein the weights of the first counterweight unit and the second counterweight unit are different.

4. The drug mixing device as claimed in claim 1, further comprising a guide module comprising a guide rail unit and a connecting unit, wherein the guide rail unit is disposed along the second direction adjacent to the mixing module side of the assembly unit, and one end of the connecting unit is disposed on the guide rail unit and the other end is disposed on the mixing module.

5. The drug mixing apparatus as described in claim 4, further comprising the connecting unit being disposed in one of the support unit and the clamping unit of the mixing module.

6. The drug mixing device as described in claim 1, further comprising a thread on the outer periphery of each counterweight linkage of the counterweight module, wherein, Each counterweight link is set at the position of the corresponding limiting hole by means of the threaded adjusting screw.

7. The drug mixing apparatus as described in claim 4, further comprising the transmission unit driving the crank unit and the counterweight module, and causing the connecting unit to move along the second direction on the guide rail unit, and causing the clamping unit of the mixing module to swing up and down.

8. The drug mixing apparatus as described in claim 4, further comprising a dovetail groove structure for the guide rail unit.
