Detailed Description

Some embodiments of the present invention will be described in more detail below with reference to the accompanying drawings to enable those skilled in the art to practice the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. These embodiments do not limit the invention, but the invention is only limited by the appended claims. Furthermore, the terminology used in the detailed description of the particular embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention.

Referring to fig. 1, a plan view of a dispensing device 1 according to an embodiment of the present invention is illustrated. The medicine dispensing device 1 of the present invention is composed of a plurality of medicine dispensing units 11, a base plate 12, and a plurality of stepping motors 13. As can be seen from fig. 1, the base plate 12 includes a plurality of pedestals 121 and supports a plurality of dispensing units 11, a plurality of stepping motors 13 are fixed to the bottoms of the plurality of pedestals 121 to controllably drive the plurality of dispensing units 11 by setting a rotation speed and a rotation time, and an engaging structure I of the plurality of pedestals 121 engages the plurality of dispensing units 11 with the plurality of pedestals 121, so that the plurality of dispensing units 11 are detachably fixed to the plurality of pedestals 121. Thus, the plurality of dispensing units 11 of the dispensing device 1 of the present invention can be replaced according to the type and size of the medicine grains, while the number of dispensing units 11 can be adjusted according to the type of prescribed medicine. For example, by using Gankang, Aspirin and amoxicillin, three medicine separation units can be used simultaneously to separate three medicine granules respectively, so that the taking requirements of different medicines are met, and the convenience is improved. As can be seen from fig. 1, the plurality of stepping motors 13 are connected to the data line, and the rotation speed and the rotation time of the plurality of stepping motors 13 can be controlled by the data line, so that the medicine particles can be dispensed from the precisely controlled dispensing unit 11. It should be noted that, the outer side of the base 121 and the bottom side of the package cavity 112 are provided with a bonding structure I capable of bonding with each other. When the medicine dispensing device is used, the packaging cavity 112 of the medicine dispensing unit 11 is inserted into the base 121 and rotated until the base 121 and the bonding structure I on the bottom side surface of the packaging cavity 112 are bonded with each other, and the medicine dispensing unit 11 is fixed in a proper position. At this time, the motor shaft of the stepping motor 13 is also inserted into the stepping motor shaft cavity 1114, and when the plurality of stepping motors 13 are operated, since the plurality of dispensing units 11 are engaged with the plurality of bases 121, the dispensing units 11 do not vibrate to be separated from the bases 121 due to the rotation of the plurality of stepping motors 13, and the safe and efficient dispensing of the medicine particles can be ensured.

The dispensing unit 11 and the substrate 12 will be described in detail below.

Referring to fig. 1, 3 and 5, a front view and a right side view of a dispensing unit 11 of one embodiment of the present invention are illustrated. The medicine distribution unit 11 of the present invention includes a medicine distribution structure 111, a packaging cavity 112 and a medicine particle distribution mechanism 113. As can be seen from fig. 1 and 3, the dispensing structure 111 includes a lower cylinder 1112 and an upper cylinder 1111 disposed on an upper surface of the upper cylinder 1111, and the upper surface of the upper cylinder 1111 is curved to protrude upward, so that the pellets do not stay on the upper surface of the upper cylinder 1111 but slide into the upper surface of the lower cylinder 1112. When the plurality of stepping motors 13 drive the lower cylinder 1112 to operate, the pellets perform centrifugal motion, and the pellets are concentrated on the pellet moving track formed by the upper cylinder 1111 and the packaging cavity 112. That is, the upper cylinder 1111 functions to guide the movement direction of the tablet, and the diameter thereof is determined according to the size of the tablet and the diameter of the packing chamber 112. Generally, the cross-sectional width of the tablet movement track is at least the smallest size of the tablet, such that the tablet movement track can accommodate at least one tablet movement. However, in practice, a plurality of pellets are concentrated on the pellet travel path. A plurality of stepper motor shaft cavities 1114 are provided at the bottom of the lower cylinder 1112, and the motor shafts of a plurality of stepper motors 13 can be inserted into the plurality of stepper motor shaft cavities 1114 to drive the lower cylinder 1112 and the upper cylinder 1111. Meanwhile, a groove is cut in the side surface of the lower cylinder 1112 along the axial direction thereof as a medicine dispensing groove 1113, and the volume of the medicine dispensing groove 1113 is the volume of one tablet. For example, when the plurality of stepping motors 13 are operated clockwise, the tablets may move clockwise on the tablet moving track, and if the rotation speed and the rotation time of the stepping motors 13 are controlled, a fixed number of tablets may fall into the dispensing slot 1113, thereby achieving precise dispensing. The packaging cavity 112 is a cylinder with a bottom sealed upper portion that may have a cap portion 1123 with a diameter just configured to enclose the lower cylinder 1112 and the lower cylinder 1112 abutting against the bottom of the packaging cavity 112. The height of the package cavity 112 is greater than the total height of the upper cylinder 1111 and the lower cylinder 1112 in the axial direction, so that more tablets can be accommodated, and the functions of storing tablets and separating out multiple tablets can be achieved. The tablet diversion mechanism 113 is disposed in a guide rail 1122 (not shown) on the side surface of the packaging chamber 112, and includes a diversion plate 1132 and a diversion rod 1131, the diversion rod 1131 is inserted into the guide rail 1122, the diversion plate 1132 is disposed at the lower end of the diversion rod 1131, and the diversion plate is axisymmetric with the diversion rod 1131, and has a plane parallel to the bottom surface of the packaging chamber 112 and an inclined plane inclined downward from the diversion rod 1131. It should be noted that before the pill is inserted, the diversion rod 1131 presses the diversion plate 1132 downward to abut against the lower cylinder 1112, otherwise the pill will prevent the diversion plate 1132 from shielding the dispensing slot 1122 in subsequent dispensing. A guide groove 1122 is provided on the outer surface of the package cavity 112 directly above the dispensing opening 1121 in the height direction thereof. The diverter bar 1131 can be moved up and down in the track slot 1122 in steps to flexibly adjust the height of the diverter plate 1132. As an example of a structure for achieving such a stepwise up-and-down movement, a plurality of saw teeth may be provided in the guide rail groove 1122 in the axial direction of the upper cylinder 1111, and a plurality of protrusions abutting against the plurality of saw teeth may be provided in the axial direction of the diversion plate 1132, so that the plurality of saw teeth and the plurality of protrusions may perform a stepwise up-and-down movement due to friction therebetween. When the dispensing unit 11 no longer needs to dispense the tablet, the tablet is removed from the dispensing device 1. According to the conventional method, the dispensing unit 11 is detached from the base 121, the cap 1123 is removed, and the medicine is discharged, but this easily contaminates the medicine and makes the operation complicated. According to the medicine distribution device 1, the medicine particle distribution mechanism 113 capable of moving up and down is arranged, when medicine particles need to be distributed, the distribution plate 1132 is pressed down to play a role in distributing the medicine particles, when the medicine particles do not need to be distributed and are taken out from the medicine distribution unit 11, the distribution plate 1132 is lifted, the distribution does not shield the medicine distribution groove 1113, the medicine distribution opening 1121 and the medicine leakage opening 1211 any more, the motor is controlled to rotate so as to drive the medicine distribution unit 11 to rotate, the medicine particles directly fall into the medicine distribution groove 1113 and are distributed from the medicine leakage opening 1211, and the medicine particles are recovered.

Referring to fig. 1 and 2, there are shown front and left side views of a dispensing unit 11 according to an embodiment of the present invention. As can be seen from fig. 1 and 2, a guide rail groove 1122 is disposed on the outer side surface of the package cavity 112 along the height direction of the package cavity directly above the dispensing opening 1121, and a pressing plate can be disposed on the top of the dispensing rod 1131, so as to conveniently adjust the vertical height of the dispensing plate 1132. Diverter plate 1132 is split into two symmetrical sections with a downward sloping ramp from diverter bar 1131. The inclined surface is provided to concentrate the medicine particles near the diversion plate 1132, because, for example, when the plurality of stepping motors 13 rotate clockwise, the medicine particles also rotate clockwise, and after encountering the inclined surface of the diversion plate 1132, the medicine particles are gradually blocked and concentrated on one inclined surface of the diversion plate 1132. Similarly, when the plurality of stepping motors 13 rotate counterclockwise, the medicine particles rotate counterclockwise, and encounter another inclined surface of the dividing plate 1132, and then are gradually blocked by another inclined surface of the dividing plate 1132. Thus, when the dispensing slot 1113 rotates to the vicinity of the diversion plate 1132, the particles can quickly fall into it. The bottom plane of the diversion plate 1132 is more than twice the cross section of the medicine distribution groove 1113. That is, the cross-sectional area of the diversion plate 1132 is larger than the cross-sectional area of the drug dispensing slot 1113 on the side of the central line of the diversion rod 1131, so that after a predetermined number of drug particles are gathered in the drug dispensing slot 1113, the diversion plate 1132 can cover the drug dispensing slot 1113, and when the drug particles fall into the drug dispensing opening 1121, the upper surface of the drug dispensing slot is covered by the diversion plate 1132, so that no other drug particles fall into the drug dispensing opening 1121, thereby precisely controlling drug dispensing. Meanwhile, as can be seen from fig. 2, the package chamber 112 is a cylinder, but the bottom surface thereof is disposed at a position having a certain height with respect to the bottom surface (virtual plane) of the cylinder. A bonding structure I (not shown) is provided on a part of the side surface of the bottom surface of the package chamber 112 facing downward, and the plurality of stepper motor shaft chambers 1114 extend substantially through the bottom surface of the package chamber 112 to the bottom surface (virtual plane) of the cylinder and abut against the base 121.

Referring to fig. 6 and 7, top and bottom views of the dispensing unit 11 of the present invention are illustrated. As can be seen from fig. 6, the diversion plate 1132 can abut downward against the tablet moving track. That is, the cross-section of the splitter plate 1132 is a torus that is concentric with the lower cylinder 1112 and the upper cylinder 1111. As can be seen from fig. 7, the plurality of stepper motor shaft cavities 1114 may have a circular cross-section, and an engaging structure H for detachably fixing the plurality of stepper motor shaft cavities 1114 is provided on the outer bottom surface of the package cavity 112 along the radial direction. Such that the dispensing structure 111 is removable from the package cavity 112.

Referring to fig. 8, a perspective view of a dispensing unit according to an embodiment of the present invention is shown. In the figure, the dispensing unit 11 has a lid 1123 for closing the package cavity 112, and a plurality of combined bonding structures I are provided on the bottom side of the package cavity 112 for bonding with the bonding structures I of the base 121, thereby fixing the package cavity 112 to the base 121.

Referring to fig. 9, 11 and 13, there are front, top and bottom views of a base plate 12 according to one embodiment of the present invention. A plurality of susceptors 121 are disposed side by side on the substrate 12, an opening 1212 is provided at the center of the susceptors 121, and a plurality of stepper motors 13 are inserted into the plurality of stepper motor shaft cavities 1114 through the opening 1212. A medicine leakage opening 1211 is formed inward on the circumference of the base 121, and medicine particles separated from the medicine separation structure 111 are separated through the medicine leakage opening 1211. As can be seen from fig. 13, the substrate 12 is a flat plate, on which a plurality of circular areas are divided side by side, the cross-sectional area of the circular areas is substantially the same as that of the package cavity 112, and bonding structures I are vertically arranged on the periphery of the circular areas, and the bonding structures I correspond to the bonding structures I on the bottom side of the package cavity 112, and are therefore arranged at intervals.

Referring to fig. 10 and 12, there are shown left side and perspective views of a substrate 12 in accordance with one embodiment of the present invention. The base plate 12 serves to support the dispensing unit 11 while the dispensing device 1 is integrated into another application device, so that the base plate 12 is configured to be able to be attached to the dispensing unit 11 (via the upper attachment structure I) or to be integrated into another application device (see the lower engaging piece of fig. 10). As can be seen in fig. 12, the base 121 is in fact a cylindrical housing in shape, which corresponds to the cylindrical design of the enclosure 112.

It should be noted that the drug granules dispensed by the dispensing device 1 of the present invention are tablets, capsules, granules, and are not suitable for other types of drugs, such as liquid dosage forms (e.g. decoction, medicated wine, lotion, injection, etc.), semisolid dosage forms (e.g. ointment, paste, etc.), and gas dosage forms (e.g. aerosol, inhalant, etc.). This is because the volume of the dispensing groove 1113 of the dispensing unit 11 of the present invention is quantified according to the number of tablets, and the tablet volume is too large, so that it is difficult to dispense tablets from the entire dispensing unit 11, and the tablet volume is too small, so that the number of tablets dispensed at one time cannot be determined, which affects the administration effect. Moreover, the tablet must be solid, which is a semisolid or liquid dosage form, the shape and volume of which cannot be determined, the volume of the dispensing groove 1113 cannot be quantified, and the number of tablets dispensed at one time cannot be determined.

The dispensing groove 1113 of the dispensing unit 11 of the present invention has a volume of one tablet. That is, each dispensing unit 11 corresponds to a specific medicine, so that the dispensing groove 1113 of the dispensing unit 11 has a volume just enough to accommodate one tablet. For example, if aspirin is a flat tablet, the dispensing slot 1113 is formed in the vertical direction to just accommodate the upright flat tablet, and this dispensing unit 11 is dedicated to dispensing aspirin. For example, the vitamin C Yinqiao capsule is a capsule, and is cylindrical as a whole, the dispensing groove 1113 is made into a cuboid shape just accommodating the vitamin C Yinqiao capsule, and the dispensing unit 11 is specially used for dispensing the vitamin C Yinqiao capsule. A plurality of dispensing units 11 may be disposed on one substrate 12, each dispensing unit 11 corresponding to a specific medicine, so that the dispensing device 1 can dispense a plurality of kinds of medicine particles at the same time.

The principle of the dispensing device 1 of the present invention is as follows: the volume of the dispensing groove 1113 of the dispensing unit 11 corresponds to the volume of the tablets, and the number of tablets dispensed by one rotation of the dispensing unit 11 is quantified, for example, the volume of the dispensing groove 1113 of the dispensing unit 11 is set to the volume of one or more tablets, and the number of tablets dispensed is controlled by controlling the rotation speed and rotation time of the motor 13. For example, 5 tablets are to be dispensed, and the volume of the dispensing tank 1113 is set to 1 tablet, and the rotation speed of the plurality of stepping motors 13 may be set to 2 rpm and the rotation time to 2.5 minutes. For example, 10 tablets are to be dispensed, and the volume of the dispensing tank 1113 is set to 2 corresponding tablets, and the rotation speed of the plurality of stepping motors 13 may be set to 2 revolutions per minute and the rotation time may be set to 5 minutes. The rotation speed and rotation time of the plurality of stepping motors 13 and the volume of the dispensing chute 1113 can be set according to the condition of the patient to take the medicine. For example, for cancer patients, the dosage is large and the types are many, more medicine dispensing units 11 can be used on the base plate 12 at the same time, and the rotating speed of the stepping motors 13 is set to be relatively large, so that more medicine granules can be dispensed in a short time, and the situation that the patient faces to the complicated prescription and takes the medicine by mistake or missing is avoided. Also, before the dispensing device 1 is operated, the sealing chamber 112 needs to be unscrewed from the base 121, the stepping motor shaft chamber 1114 is manually rotated to align the dispensing slot 1113, the dispensing opening 1121 and the dispensing leakage opening 1211, and then the sealing chamber 112 is bonded to the base 121 again. This is to adjust the initial position of the dispensing groove 1113 of the dispensing structure 111 of the dispensing unit 11, ensure that each initial starting position of the dispensing structure 111 is the same and is at a position where the dispensing groove 1113, the dispensing port 1121 and the medicine leakage port 1211 are aligned, and set the rotation speed and time of the plurality of stepping motors 13 according to the number of medicine grains to be dispensed by connecting with external input and control means such as a circuit board and display means through data lines with the stepping motors 13. This is because the stepping motor 13 rotates once, and the dispensing groove 1113 of the dispensing structure 111 rotates once from the positions corresponding to the dispensing opening 1121 and the dispensing opening 1211, and then returns to the positions corresponding to the dispensing opening 1121 and the dispensing opening 1211, and at this time, dispensing is performed just once. Therefore, the separated medicine particles can be controlled by setting the rotating speed, so that the medicine can be accurately separated.

Next, the operation of the dispensing device 1 of the present invention for dispensing is explained. Before the dispensing device 1 is operated, the packaging chamber 112 is unscrewed from the base 121, the stepping motor shaft chamber 1114 is manually rotated to align the dispensing slot 1113, the dispensing port 1121 and the medicine leakage port 1211, and then the packaging chamber 112 is bonded to the base 121 again. The diverter plate 1132 is pressed against the bottom of the lower cylinder 1112. The appropriate amount of pellets is poured into the package cavity 112 and the lid 1123 is closed. The pellet falls onto the upper surface of upper cylinder 1111 and, because of the curvature imparted by the upper surface, slides onto the surface of lower cylinder 1112 and into the pellet travel path defined by upper cylinder 1111 and enclosure 112. At this time, a predetermined number of tablets enter the dispensing chute 1113, and the dispensing chute 1113 is away from the flow distribution plate 1132, and one tablet falls into the dispensing chute 1113. The data lines of the plurality of stepping motors 13 are connected to an external control device, and the plurality of stepping motors 13 are turned on. Lower cylinder 1112 and upper cylinder 1111 begin to rotate. When the dispensing slot 1113 rotates to a position close to the end of the diversion plate 1132, the diversion plate 1132 starts to push the medicine particles near the dispensing slot 1113 in the opposite direction, so that the medicine particles which do not enter the dispensing slot 1113 are separated from the medicine particles which enter the dispensing slot 1113. Next, the dispensing groove 1113 overlaps the dispensing port 1121 with a predetermined number of tablets, and the tablets fall into the dispensing port 1211 to complete a single-rotation dispensing process, which corresponds to the rotation speed and the rotation time of the stepping motor 13, that is, when the volume of the dispensing groove 113 is the volume of one tablet, the number of tablets dispensed is equal to the rotation speed × the rotation time. For example, one tablet is dispensed in a single time, the rotating speed is 2 revolutions per minute, and 4 tablets to be dispensed, the rotating time is 2 minutes. Thereby dispensing a predetermined number of tablets by controlling the rotational speed and rotational time of the stepping motor 13.

Obviously, modifications and/or additions of parts may be made to the dispensing device 1 as described heretofore, without departing from the field and scope of the present invention.

It should also be clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of dispensing device, including the corresponding features as set forth in the claims and hence all coming within the field of protection defined thereby.
