The supply unit according to an embodiment will be described with reference to FIGS. 6 to 11. FIG. 6 is a perspective view of a supply unit in a state where the drug gathering units are stacked according to an embodiment, FIGS. 7 to 9 are a partial cutoff perspective view, a plan view, and a rear perspective view of the supply unit according to an embodiment, and FIGS. 10 and 11 are schematic views of a state in which the supply unit discharges the drug gathering unit according to an embodiment.
Referring to FIG. 6, a plurality of drug gathering units 30 are stored within the supply unit 100 in a state where the plurality of drug gathering units 30 are stacked on each other. The supply unit 100 may sequentially discharge the stacked drug gathering units 30 downward in order from the lowermost drug gathering unit 30.
Referring to FIGS. 7 and 8, the supply unit 100 includes at least two discharge parts 110 on the edge portion of the drug gathering unit 30. The discharge parts 110 may be disposed on at least facing two sides of the drug gathering unit 30.
Each of the discharge parts 110 receives rotation force generated by a motor 190 through a power transmission part 191 to rotate. Also, the discharge parts 110 may be connected to each other by using a bevel gear to rotate together with each other.
The discharge part 110 may discontinuously rotate. Here, various detection units may be provided to control rotation and stop of the discharge parts 110. For example, as shown in FIG. 9, a detection target unit 181 includes projections radially protruding from a rotation shaft thereof and a sensor unit 182 for detecting the approach of the corresponding projection. Various types of sensors may be used as the sensor unit 182. For example, an infrared sensor including a light emitting part and a light receiving part to detect the projection between the light emitting part and the light receiving part may be used as the sensor unit 182.
Referring to FIGS. 10 and 11, the discharge part 110 includes a rotation shaft 111 and protrusions 113. The protrusions 113 protrude from the rotation shaft 111 and are radially disposed around the rotation shaft 111 at a predetermined distance. That is, the protrusions 113 may be disposed around the rotation shaft 111 at a predetermined angle. Here, a roll or roller for reducing friction force may be disposed on an end of each of the protrusions 113.
The protrusion 113 of the discharge part 110, which is disposed on a side of the drug gathering unit 30 supports the lowermost drug gathering unit 30. Here, when the discharge part 110 rotates, the protrusion 113 returning to the drug gathering unit 30 supports the second drug gathering unit 30 from a lower side. Here, as the discharge part 110 rotates, the protrusion 113 supporting the lowermost drug gathering unit 30 may rotate downward to release and discharge the drug gathering unit 30 supported thereto.
The introduction-side seat unit 410 may be disposed under the drug gathering unit 30 before the drug gathering unit 30 is discharged. Referring to FIG. 11, the introduction-side seat unit 410 may descend again after the discharged drug gathering unit 30 is seated to move to a position at which the drugs introduced from the outside are seated.
A process in which the drug gathering unit gathers introduced drugs to transfer the gathered drugs to the drug transfer cart and the drug transfer cart according to an embodiment will be described with reference to FIGS. 12 to 26. FIGS. 12 to 26 are views illustrating successive processes in which the drug gathering unit gathers introduced drugs to transfer the gathered drugs to the drug transfer cart according to an embodiment.
A process of gathering introduced drugs to transfer the gathered drugs to the drug transfer cart is as follows.
As shown in FIG. 12, the introduction-side seat unit 410 ascends through the introduction-side elevation unit 400 to approach a lower portion of the supply unit 100.
Next, as shown in FIG. 13, the lowermost drug gathering unit 30 is discharged and seated on the introduction-side seat unit 410, and then, the introduction-side seat unit 410 descends. As shown in FIG. 14, the drug gathering unit 30 descends until the drug gathering unit 30 is disposed above the transfer unit 200.
When the discharged drug gathering unit 30 is disposed above the transfer unit 200, the damage prevention unit 420 operates as described above. That is, as shown in FIG. 15, when the rotation shaft 425 descends along the guide groove 4271 of the cam part 427, the inclination formation part 429 forms an inclination while being pushed from the inside of the drug gathering unit 30 in a direction D1 in which the drugs are introduced.
Next, as shown in FIG. 16, after an external device 40 is disposed above the drug gathering unit 30, the drugs are introduced into the drug gathering unit 30 from the external device 40. Here, the introduced drugs are seated on the inclination formation part 429 and then accommodated into the drug gathering unit 30. The introduced drugs may be mitigated in impact by the inclination formation part 429 to reduce possibility of damage. The drugs gathered one time may be drugs corresponding to one person's prescription or drugs corresponding to prescriptions for patients in one hospital room or one hospital ward. That is, the present invention is not limited to the number of drugs gathered one time, and thus, drugs may be classified and gathered through various methods according to a system management method.
Then, as shown in FIG. 17, after the drugs are accommodated into the drug gathering unit 30, the inclination formation part 429 of the damage prevention unit 420 is separated from the drug gathering unit 30. Thereafter, as shown in FIG. 18, the transfer unit 200 transfers the drug gathering unit 30 in a direction of the cart accommodation unit 16, i.e., to an upper side of the cart-side seat unit 450.
As necessary, as shown in FIG. 19, drugs may be received from the other external device 41. In this case, the drug gathering unit 30 may be disposed outside an operation range of the damage prevention unit 420. Thus, the introduced drugs to be packaged with a box may be drugs having low damage possibility.
Next, as shown in FIG. 20, the cart-side seat unit 450 ascends to allow the drug gathering unit 30 disposed above the cart-side seat unit 450 to ascend. Here, the cart-side elevation unit 440 elevates the cart-side seat unit 450 up to a specific position.
As shown in FIG. 21, the drug transfer cart 20 is accommodated above the cart-side seat unit 450, i.e., into the cart accommodation unit 16. As shown in FIG. 22, the cart-side elevation unit 440 elevates the cart-side seat unit 450 to elevate the drug gathering unit 30 up to a specific position within the drug transfer cart 20. Then, as shown in FIG. 23, the drug gathering units 30 are filled from the uppermost position of the drug transfer cart 20.
Here, a hook 23 is disposed along a moving path of the drug gathering unit 30 inside a cart frame 21 defining an outer appearance of the drug transfer cart 20. The hook 23 may restrict the drug transfer cart 22 so that the drug transfer cart 22 passes in one direction. In detail, a hook member 231 of the hook 23 rotates about a shaft 232 fixed to the cart frame 21. Here, a stopper 234 may contact the cart frame 21 to restrict the hook member 231 so that the hook member 231 rotates only toward the cart frame 21. That is, since the hook member 231 is pushed by an edge of the drug gathering unit 30 to rotate toward the cart frame 21 when the drug gathering unit 30 ascends, the hook member 231 may pass through the drug gathering unit 30. On the other hand, when the drug gathering unit 30 descends, the hook member 231 supports the edge of the drug gathering unit 30 to prevent the drug gathering unit 30 from further descending. An elastic part 233 having compressive elasticity is disposed between the hook member 231 and the cart frame 21. The elastic part 233 allows the hook member 231 to return to its original position by using elastic force thereof when the hook member 231 is pushed toward the cart frame 21.
The drugs gathered into the drug gathering unit 30 may be accommodated into the drug transfer cart 20 through the above-described processes as shown in FIG. 25. The drug transfer cart 20 may be separated in one direction in the state where the drug transfer cart 20 accommodates the drug gathering units containing drugs.
The drug transfer cart 20 is separated to move so as to transfer the drugs to each of patients. As shown in FIG. 26, the drug transfer cart 20 may be movable by using a wheel 25. Also, after the drug transfer cart 20 reaches a patient, the drug gathering unit 30 may be withdrawn in a withdrawal direction D6 to convey the drugs to the patient.
A damage prevention unit according to another embodiment will be described with reference to FIGS. 27 and 28. FIGS. 27 and 28 are perspective views of a damage prevention unit according to another embodiment.
A damage prevention unit 420 a according to the current embodiment is different from the above-described elevation-type damage prevention unit in that the damage prevention unit 420 a rotatably operates.
The damage prevention unit 420 a according to the current embodiment includes a power transmission part 4211, a driving shaft 4212, a driven shaft 422, a rotation arm 4213, and an inclination formation part 429 a.
The driving shaft 4212 receives rotation force from the power transmission part 4211 to rotate in a first direction or a second direction that is a reverse direction of the first direction. Here, the rotation arm 4213 is fixed to the driving shaft 4212. Thus, as the driving shaft 4212 rotates, the rotation arm 4213 rotates between an upper portion of the driving shaft 4212 and an upper portion of a drug gathering unit 30.
The driven shaft 422 is rotatably fixed to the other side of the driving shaft 4212 of ends of the rotation arm 4213. Also, the driven shaft 422 is connected to the driving shaft 4212 by using a gear and a timing belt to receive the rotation force. Here, the driven shaft 422 rotates in a direction opposite to the rotation direction of the driving shaft 4212.
Thus, when the inclination formation part 429 a rotates in a direction opposite to that of the rotation arm 4213, the rotation arm 4213 downwardly stands upright. Also, when the rotation arm 4213 rotates in a clockwise direction toward the drug gathering unit 30, the inclination formation part 429 a rotates in a counterclockwise direction to form an inclination toward a bottom surface of the drug gathering unit 30.
The inclination formation part 429 a according to the current embodiment may also minimize dropping impacts when the drugs are introduced from the outside. In the current embodiment, to secure an operation range of the damage prevention unit 420 a, the drug gathering unit 30 may have a length direction parallel to that of a transfer unit 200.
A drug transfer cart according to another embodiment will be described with reference to FIG. 29. FIG. 20 is a perspective view of a drug gathering apparatus including a drug transfer cart according to another embodiment.
A drug transfer cart 20 a according to the current embodiment includes an openable cart door 201 a. The cart door 201 a may be provided in various types such as a hinge type or a separation type. The cart door 201 a may be configured to withdraw the drug gathering units 30 that are stacked within the drug gathering cart 20 a to the outside even though the drug transfer cart 20 a is accommodated within a drug gathering apparatus la.
The drug gathering apparatus according to the present invention may gather drugs introduced by accurately repeatedly supplying the drugs dispensed from the external device to the drug gathering unit to maximize work efficiency.
Also, when drugs according to a patient's prescription are transferred, a separate process for classifying the gathered drugs may not be needed to simply the drug transfer process.
Although exemplary embodiments of the present invention are described, the technical spirit of the present invention is not limited to the above-described exemplary embodiments, and thus various drug gathering apparatus can be realized without departing form the spirit or scope of the invention.
