Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of external cooling for drug dispensing systems, and in particular to a drug dispensing system with external cooling. Background Technology
[0002] External refrigeration in a pharmaceutical preparation system typically refers to the use of external refrigeration equipment (such as refrigerators, cooling devices, etc.) to control the ambient temperature during the preparation process to ensure the quality and efficacy of drugs, reagents, or other chemical substances. Unlike the internal cooling equipment or built-in temperature control system of the pharmaceutical products themselves, the external refrigeration system mainly regulates the temperature of the entire preparation environment to ensure that it meets the requirements for drug storage and use.
[0003] The dissolution and preparation of chemical pharmaceuticals releases a significant amount of heat. If this exothermic reaction is not properly controlled, it can easily lead to component volatilization, boiling, and damage or deformation of the preparation container. Some drugs' active ingredients may be highly sensitive to temperature changes, and some drugs require preparation within specific temperature ranges. External refrigeration systems ensure that pharmaceuticals remain within their optimal temperature range during preparation, preventing reduced efficacy or deterioration due to temperature fluctuations. External refrigeration equipment also helps maintain the stability of the operating environment, preventing temperature fluctuations from affecting drug preparation and quality.
[0004] Currently, most external refrigeration methods for drug dispensing systems involve installing heat exchangers inside the dispensing tank for temperature control. These refrigeration methods have the following technical problems: 1. Drug quality issues: Solid drugs are prone to depositing in the gaps of the exchange pipes, affecting the production concentration; 2. Difficult maintenance: Once scale or damage occurs on the exchange pipes, repairs are very difficult; 3. Low working efficiency: The exchange efficiency decreases with production time, and the corrosion resistance to the drug solution is limited. Utility Model Content

[0019] Beneficial effects
[0020] 1. This utility model provides a dispensing system with external cooling. The dispensing system includes a dispensing component, an automatic dosing component, and a cooling component on one side of the dispensing component. The dispensing component includes a dispensing tank located below the automatic dosing component. A stirring motor is installed on the dispensing tank. A water inlet pipe is installed on one side of the stirring motor. A water outlet pipe is installed below the dispensing tank. A first solenoid valve is installed on the water outlet pipe. A branch pipe is installed on one side of the water outlet pipe. A second solenoid valve and a pipeline pump are respectively installed on the branch pipe. The dispensing system with external cooling has a simple overall structure, is easy to install and maintain, and facilitates the preparation of chemical drugs by staff.
[0021] 2. This utility model provides a dispensing system with external cooling. The designed automatic dispensing component includes a dispensing system located above the dispensing tank, a third solenoid valve located below the dispensing system, and a temperature sensor located inside the dispensing tank below the third solenoid valve. During the preparation of chemical drugs, the dispensing system of this automatic dispensing component adds the drug to the dispensing tank below. After the drug enters the tank, it dissolves with the liquid, releasing a large amount of heat. This heat dissipation raises the temperature inside the tank. When the temperature reaches a certain level, the temperature sensor inside the tank sends the temperature to the third solenoid valve. The third solenoid valve receives the signal and transmits it to the dispensing system, stopping the addition of drug to the tank. This prevents the drug from evaporating or boiling due to excessive temperature, which could damage or deform the dispensing tank and reduce the quality of the prepared drug.
[0022] 3. This utility model provides a dispensing system with external cooling. The system's cooling component includes a chiller located on one side of the dispensing component. A chilled water pipe is installed on one side of the chiller, and a cooling fin is connected to one end of the chilled water pipe. A refrigeration chamber is installed outside the cooling fin. After the drugs in the dispensing tank are prepared, the liquid medicine flows out through the outlet pipe below the dispensing tank to a branch pipe on one side of the outlet pipe, and then flows into the refrigeration chamber through the branch pipe. By turning on the chiller, compressed refrigerant gas is pumped through the chilled water pipe to the cooling fin. The cooling fin interacts with the compressed high-pressure gas, lowering its temperature, thereby lowering the temperature of the liquid medicine in the refrigeration chamber installed outside the cooling fin. The cooled liquid medicine then flows back into the dispensing tank through the inlet pipe, forming a cold circulation system for dispensing chemical drugs. This cooling component design helps to cool the prepared drugs in a timely manner, preventing drug failure due to excessively high temperatures inside the dispensing tank, and improving the quality and efficiency of chemical drug preparation.

To make the practical purpose, technical solution and advantages of this utility model clearer, the specific operation process of this utility model will be described in detail below with reference to the accompanying drawings and the working process of this device.
[0037] This utility model provides a dispensing system with external cooling, including a dispensing component 1, an automatic dispensing component 2 on the dispensing component 1, and a cooling component 3 on one side of the dispensing component 1.
[0038] The dosing assembly 1 includes a dosing tank 101 located below the automatic dosing assembly 2. A stirring motor 102 is installed on the dosing tank 101. A water inlet pipe 108 is installed on one side of the stirring motor 102. A water outlet pipe 103 is installed below the dosing tank 101. A first solenoid valve 104 is installed on the water outlet pipe 103. A branch pipe 105 is installed on one side of the water outlet pipe 103. A second solenoid valve 106 and a pipeline pump 107 are respectively installed on the branch pipe 105.
[0039] The automatic dosing assembly 2 includes a dosing system 202 located above the dosing tank 101, a third solenoid valve 201 located below the dosing system 202, and a temperature sensor 203 located inside the dosing tank 101 located below the third solenoid valve 201.
[0040] The cooling assembly 3 includes a chiller 301 located on one side of the dispensing assembly 1. A chilled water pipe 302 is provided on one side of the chiller 301. One end of the chilled water pipe 302 is connected to a cooling plate 303. A refrigeration box 304 is provided outside the cooling plate 303.
[0041] See Figures 1 to 6 Multiple cold water pipes 302 are provided, and the axes of the multiple cold water pipes 302 are parallel. The third solenoid valve 201 is located between the dosing system 202 and the dosing tank 101. The pipeline pump 107 is located between the second solenoid valve 106 and the refrigeration box 304. The horizontal cross-section of the cooling plate 303 is parallel to the horizontal cross-section of the refrigeration box 304. The refrigeration box 304 is located between the branch pipe 105 and the inlet pipe 108. The branch pipe 105 is located between the outlet pipe 103 and the refrigeration box 304. The axis of the branch pipe 105 is parallel to the axes of the multiple cold water pipes 302.
[0042] See Figures 1 to 5 The central axis of the stirring motor 102 and the axis of the medicine mixing tank 101 are on the same straight line.
[0043] The working principle and specific workflow of a drug dispensing system with external cooling are as follows: According to the overall structural design of the drug dispensing system with external cooling, the drug dispensing system 202 of the automatic drug dispensing component 2 is installed on the drug dispensing tank 101, and the third solenoid valve 201 is installed between the drug dispensing tank 101 and the drug dispensing system 202. The temperature sensor 203 is installed inside the drug dispensing tank 101, and the cooling component 3 is installed on one side of the drug dispensing component 1 and connected to each pipe. After installation is completed;
[0044] The automatic dosing assembly 2 dispenses drugs into the lower drug tank 101 through the dosing system 202. After the drugs enter the drug tank 101, they dissolve with the liquid, releasing a large amount of heat. The heat dissipation causes the temperature inside the drug tank 101 to rise. When the temperature rises to a certain level, the temperature sensor 203 inside the drug tank 101 sends the temperature inside the tank to the third solenoid valve 201. The third solenoid valve 201 receives the signal and transmits it to the dosing system 202 to stop dispensing drugs into the drug tank 101. This prevents the drugs from evaporating or boiling due to excessive temperature, which could cause the drug tank 101 to burn or deform, and reduce the quality of the drug preparation.
[0045] After the drugs in the mixing tank 101 are prepared, the liquid medicine flows out through the outlet pipe 103 at the bottom of the mixing tank 101 to the branch pipe 105 on one side of the outlet pipe 103, and then flows into the refrigeration box 304 through the branch pipe 105. By turning on the chiller 301, the chiller 301 delivers cold water to the cooling plate 303. The cooling plate 303 uses the cold water (low temperature water) delivered from the chiller 301 to cool the liquid medicine in the refrigeration box 304, thereby lowering the temperature of the liquid medicine in the refrigeration box 304 installed outside the cooling plate 303. The cooled liquid medicine flows back to the mixing tank 101 through the inlet pipe 108, forming a cold circulation of liquid medicine for the preparation of chemical drugs. The design of this cooling component 3 helps to cool the prepared drugs in a timely manner, preventing the drugs from becoming ineffective due to excessive temperature in the mixing tank 101, and helps to improve the quality and efficiency of chemical drug preparation.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
