Description

Technical Field

[0001] The present invention relates to the technical field of automatic medicine preparation equipment, and in particular to an automatic medicine preparation device for ampoule injections and a use method thereof. Background Art

[0002] Currently, the preparation of intravenous medications and surgical medications in hospitals is typically done manually. Large hospitals perform dozens of surgeries and thousands of infusions daily, requiring the cutting, disinfection, and opening of numerous ampoules before syringes can be used to draw medication for injection and surgical procedures. Often, this preparation work must be completed within a single timeframe. The intense workload places significant pressure on medical staff. Statistics show that 90% of medical staff involved in ampoule preparation have experienced varying degrees of scratching from the ampoule due to stress and fatigue. In environments with severe infectious diseases, this can even lead to infection among medical staff and contaminate medications. This is particularly true during emergencies, where patients need urgent care within a short timeframe. This demands a more precise and efficient preparation process to ensure optimal patient treatment time. At the same time, large-scale emergency first aid often needs to be carried out in the wild, under harsh air and environmental conditions. It is impossible to have the sterile preparation environment of hospital wards and operating rooms. Preparation of medicines in exposed environments makes the medicines easily contaminated. Medical staff who are scratched by ampoules in such environments will suffer serious infection consequences. Although there are a large number of automatic medicine preparation devices, such as inventions: CN111803376 A and CN118992941 A, they do not conform to the actual daily use habits of medical staff and cannot meet the needs in emergency situations. Therefore, front-line medical staff urgently need an effective tool that can facilitate them to achieve efficient and safe medicine preparation. Summary of the Invention

The ampoule holder module features a cutout and folding feature located on the neck of the holder after the ampoule is placed. During transportation and dispensing, the ampoule remains securely placed within the holder's hollow structure.

[0010] A syringe fixing module features an external slot slide and protective housing, and internally houses the syringe's barrel holder and piston handle stopper. The piston handle stopper is capable of horizontal movement relative to the barrel holder, extending along the barrel holder's extension. During transportation and dispensing, the syringe's barrel is secured to the barrel holder, and the syringe's piston handle is secured to the piston handle stopper.

[0011] A method of using a medical drug preparation device and a drug preparation process are described as follows: Step 1: Install the ampoule containing the medicine into the ampoule fixing module holder, and install the syringe for the medicine into the syringe fixing module; Step 2: Push the ampoule fixing module with the medicine to be prepared installed into the ampoule fixing module card slot of the medicine preparation module, and push the syringe fixing module with the medicine preparation syringe installed into the syringe fixing module card slot of the medicine preparation module; Step 3: Set up the medicine preparation module, and the controller completes the medicine preparation operation through the set process; Step 4: Control the medicine preparation module to pop out the ampoule bottle fixing module and the syringe fixing module with the prepared medicine.

[0012] In order to use the medical drug preparation device of the present invention more effectively, preferably, the first step of the above drug preparation process is completed during the hospital's drug dispensing process; the second step is completed just before the drug is used; the third step, the process set by the controller includes cutting the neck of the ampoule bottle, disinfecting the neck, bending the neck and using a syringe to complete the extraction of the drug; the fourth step, the syringe in the prepared syringe fixing module is used as needed, and the syringe in the prepared syringe fixing module is used as needed. After taking out the empty ampoule bottle and the prepared syringe, the prepared ampoule fixing module and the syringe fixing module repeat the previous steps to complete the new drug preparation process.

[0013] The technical effects and advantages of the device of the present invention: The present invention provides a modular medical drug preparation device that can provide automated drug preparation work in various working environments. In a hospital environment, by configuring batches of ampoule bottle fixing modules and syringe fixing modules, batch drug preparation can be achieved, reducing the workload of medical staff in the drug preparation process, reducing labor intensity, and reducing operational failures caused by busyness and fatigue during drug preparation work. At the scene of an emergency outdoor accident, a closed drug preparation environment can be used to reduce the risk of drug contamination in the outdoor dirty environment during the drug preparation process. At the same time, batch use can improve drug preparation efficiency and reduce the need to queue for drug preparation due to insufficient medical staff in the drug preparation process, which will delay the best time for rescue. Regardless of the scenario, medical staff do not participate in the ampoule neck bending action during the drug preparation process, avoiding accidents caused by accidental scratches due to ampoule neck bending, and protecting the health and safety of medical staff.
