Description

Technical Field

[0001] This utility model belongs to the field of medicine dispensing technology, specifically relating to a medicine dispensing device for hospital pharmacy departments. Background Technology

[0002] In hospital pharmacy, precise control of drug dosage is crucial. For round tablets, the uniformity of their division directly affects the patient's treatment outcome. However, in practice, due to the variety of tablet sizes and specifications, traditional dispensing methods often fail to guarantee accurate division for all sizes of tablets. For example, the anti-anxiety drug alprazolam requires gradually changing dosages, ranging from a quarter to two tablets per oral dose. However, due to its small size, operators cannot accurately divide the drug along the radial direction of the tablet.

[0003] Traditional manual medication dispensing methods, such as using a scalpel or mortar and pestle, rely heavily on the pharmacist's experience and feel. When dealing with round tablets of varying sizes, the pharmacist needs to manually adjust their position to ensure even division. However, this manual adjustment method is not only time-consuming and labor-intensive but also makes it difficult to guarantee accuracy each time. Especially when handling large quantities of tablets, pharmacists are prone to errors due to fatigue or distraction, resulting in uneven tablet division and affecting the patient's medication efficacy. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a dispensing device for hospital pharmacy, which solves the problem that while existing dispensing devices improve the accuracy of dispensing to a certain extent, they often lack the ability to flexibly respond to changes in drug specifications, and the dispensing blades are inconvenient to replace, thus limiting their widespread application.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dispensing device for hospital pharmacy, comprising a base, a bracket, a reinforcing plate, and an internal threaded seat mounted on the base; a controller and an electric push rod mounted on the bracket; a detachable dispensing blade mounted on the reinforcing plate; a pressure plate mounted on the bottom end of the electric push rod; and a detachable dispensing blade threadedly connected to the internal threaded seat. The detachable dispensing blade includes a screw, a blade holder, and a blade. The reinforcing plate is connected to one end of a fixed plate in a drug centering assembly. Multiple rotating shafts are rotatably mounted on the fixed plate. Pulleys and rotating arms are mounted on the rotating shafts. The multiple pulleys are connected by a transmission belt. The multiple rotating arms are arranged around the center point of the top surface of the blade.

[0006] The beneficial effects of this utility model are as follows: by using the drug centering component, round drugs of different sizes can be quickly moved to the center of the top surface of the blade, ensuring that the drugs maintain a stable central position during the cutting process; at the same time, the detachable drug-dispensing blade can be easily installed and removed through the threaded structure, allowing users to replace drug-dispensing blades of different sizes as needed to meet the needs of different dosages.

[0008] As a further improvement to the above technical solution: the top of the reinforcing plate is connected to the side of the bracket, and the reinforcing plate and the bracket form a triangular bracket structure.

[0009] The beneficial effects of this improvement are: the reinforcing plate can provide support for the bracket, effectively improving the support stability of the bracket.

[0010] In order to keep the axis of the circular tablet collinear with the center of the top surface of the blade by rotating the rotating arm;

[0011] As a further improvement to the above technical solution: the number of rotating arms is three, and they are equidistantly spaced around the center point of the top surface of the blade.

[0012] The beneficial effects of this improvement are: after the three rotating arms rotate, they achieve tangential contact with the side of the tablet through three-point support, thereby keeping the axis of the circular tablet collinear with the center of the top surface of the blade.

[0013] To make rotating the arm easier;

[0014] As a further improvement to the above technical solution: a handle is installed at the top of one of the shafts.

[0015] The beneficial effect of this improvement is that the operator can hold the handle and drive the rotating arm to rotate with less effort.

[0016] To avoid contamination of the belt drive components by pills;

[0017] As a further improvement to the above technical solution: a groove is provided on the fixing plate on the inner side of the transmission belt to accommodate the installation of the inner baffle, and the bottom end of the inner baffle is not higher than the bottom surface of the pulley.

[0018] The beneficial effects of this improvement are: the inner baffle acts as a shield, preventing the tablets from sticking to the belt drive assembly and being difficult to clean during the dispensing process.

[0019] To enable convenient replacement of the detachable dispensing blade;

[0020] As a further improvement to the above technical solution: the screw is threadedly connected to an internal threaded seat, and the upper and lower ends of the tool holder are respectively connected to the blade and the screw.

[0021] The beneficial effects of this improvement are: the detachable dispensing knife can be easily installed and removed through the threaded structure, allowing users to replace different specifications of dispensing knives as needed to meet the requirements of different dosage division.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Example 1:

[0030] like Figure 1As shown in Figure 4: A dispensing device for hospital pharmacy includes a base 1, on which a bracket 2, a reinforcing plate 4, and an internally threaded seat 9 are mounted. A controller 3 and an electric push rod 5 are mounted on the bracket 2. A detachable dispensing blade 8 is mounted on the reinforcing plate 4. A pressure plate 6 is mounted at the bottom end of the electric push rod 5. The internally threaded seat 9 is threadedly connected to the detachable dispensing blade 8. The detachable dispensing blade 8 includes a screw 81, a blade holder 82, and a blade 83. The reinforcing plate 4 is connected to one end of a fixed plate 71 in a drug centering assembly 7. Multiple rotating shafts 72 are rotatably mounted on the fixed plate 71. The rotating shaft 72 is equipped with pulleys 73 and rotating arms 76. Multiple pulleys 73 are connected by a transmission belt 75. Multiple rotating arms 76 are arranged around the center point of the top surface of the blade 83. The drug centering assembly 7 quickly moves round drugs of different sizes to the center of the top surface of the blade 83, ensuring the drugs maintain a stable centered position during the cutting process. Simultaneously, the detachable dispensing blade 8 can be easily installed and removed via a threaded structure, allowing users to replace it with different sizes to meet different dosage cutting needs. The top of the reinforcing plate 4... The reinforcing plate 4 and the support 2 form a triangular support structure, with the reinforcing plate 4 providing support for the support 2 and effectively improving the support stability of the support 2. There are three rotating arms 76, equidistantly spaced around the center point of the top surface of the blade 83. After rotation, the three rotating arms 76 achieve tangential contact with the side of the tablet through three-point support, thereby ensuring that the axis of the circular tablet is collinear with the center of the top surface of the blade 83. A handle 77 is installed at the top of one of the rotating shafts 72, allowing the operator to easily rotate it by holding the handle 77. When the arm 76 rotates, a groove is provided on the fixing plate 71 on the inner side of the transmission belt 75 to accommodate the installation of the inner baffle 74. The bottom end of the inner baffle 74 is not higher than the bottom surface of the pulley 73. The inner baffle 74 serves to shield the pills and prevent them from sticking to the belt drive assembly during the dispensing process, which would be difficult to clean. The screw 81 is threadedly connected to the inner thread seat 9. The upper and lower ends of the blade holder 82 are respectively connected to the blade 83 and the screw 81. The detachable dispensing blade 8 can be easily installed and removed through the threaded structure, allowing users to replace different sizes of dispensing blades as needed to meet the requirements of different dosages.

[0031] The working principle of this technical solution is as follows: The tablet is placed on the blade 83, and then the handle 77 is rotated, which drives a shaft 72 to rotate. When the shaft 72 rotates, it drives the pulley 73 mounted on it to rotate. The pulley 73 then drives the other pulleys 73 to rotate synchronously through the transmission belt 75. When the pulleys 73 rotate, they drive the rotating arm 76 to rotate, thereby adjusting the diameter of the tangent circle between the three rotating arms 76 to the diameter of the tablet. Thus, the rotating arm 76 pushes the tablet to be centered on the blade 83. Then, the operator controls the piston rod of the electric push rod 5 to extend through the controller 3, which drives the pressure plate 6 to move down and press the tablet, achieving the purpose of accurately splitting the tablet.
