Description

Technical Field

[0001] The utility model relates to the technical field of medical analgesia, in particular to an automatic medicine dispensing device for an analgesic pump. Background Art

[0002] Pain is the fifth vital sign after body temperature, pulse, respiration and blood pressure, and is understood by more and more people. It is the basic right of patients to demand no pain. With the continuous promotion of comfort diagnosis and treatment, more and more patients require continuous analgesia after surgery to relieve pain. For patients undergoing thoracotomy, laparotomy with long incisions and major orthopedic surgery, good postoperative analgesia can not only enable patients to move early, reduce the occurrence of lower limb thrombosis and pulmonary embolism, and promote early recovery of gastrointestinal function; it can also reduce the release of catecholamines and other stress hormones in the patient's body after surgery, which is beneficial to lowering heart rate, preventing postoperative hypertension, reducing myocardial work and oxygen consumption, and is particularly beneficial for patients with heart dysfunction.

[0003] At present, the clinical use of analgesic pumps is one of the important methods for managing acute and chronic pain. Through continuous intravenous, epidural, intrathecal and other routes of drug administration, a stable drug concentration can be maintained to produce a satisfactory analgesic effect, and patients can press the drug themselves to quickly enhance the effect, making analgesia more individualized. The configuration of analgesic pumps is usually that medical personnel draw analgesics and stomach-protecting and antiemetic drugs into normal saline for dilution and then inject them into a pulse pump head or a disposable pump head. Most of the analgesics and stomach-protecting and antiemetic drugs are stored in ampoule bottles. Extracting the drug solution requires manually breaking the neck of the ampoule. Manual operation has the risk of drug contamination, increasing the possibility of iatrogenic infection in patients, and the process of breaking the ampoule may scratch the hands, leading to Medical staff are injured. In addition, when the drug is manually injected into the saline solution for dilution and then injected into the pump head, the drug may not be fully mixed, which will affect the patient's postoperative analgesic effect and increase the related side effects of analgesics such as nausea, vomiting, and dizziness. At the same time, with the increasing popularity of analgesic pumps, the number of analgesic pumps that anesthesiologists need to configure is gradually increasing, which will greatly increase the workload and make the problem of patients' demand for analgesic pumps and the inability of medical staff to provide matching analgesic services increasingly prominent. In addition, most of the existing analgesic drug configuration strategy records are manually operated, and there is no systematic automated statistical device, which is not conducive to promoting the optimization of clinical analgesic pump drug configuration strategies.

[0004] Chinese utility model patents CN 201870959U and CN 206838002 U respectively introduce a closed analgesic pump drug capsule dispenser and an analgesic drug dispensing device, which shortens the time spent on preparing analgesic pumps by changing the configuration process of analgesic pumps, but requires extracting the drug stock from the anesthesia chamber to the drug storage bin, and the extraction process is still a manual operation, which will increase the workload of anesthesiologists; and the drug solution and saline in the device cannot be fully mixed, which may affect the patient's postoperative analgesic effect and increase the side effects of analgesics. The device also cannot collect analgesic pump configuration data, which is not conducive to promoting the optimization of clinical analgesic pump drug configuration strategies.

[0005] Chinese invention patent CN110075385A introduces an analgesic pump configuration instrument, which automatically injects the drug solution into the analgesic pump through automatic pumping steps, but the extraction and injection of the original drug solution still need to be manually operated from the ampoule, and the extracted drug solution and saline cannot be fully mixed. In addition, the configuration process is open, and the liquid preparation device and the surrounding environment cannot be guaranteed, which increases the possibility of drug contamination. The device cannot collect analgesic pump configuration data, which is not conducive to promoting the optimization of clinical analgesic pump drug configuration strategy.

[0006] Problems with the prior art:

[0007] During the configuration of the analgesic pump, the liquid medicine needs to be manually broken and then used for extraction. Manual operation has the risk of liquid medicine contamination, increasing the possibility of iatrogenic infection in patients, and the process of breaking and laparotomy may scratch the hands, causing injuries to medical staff. In addition, the liquid medicine and saline cannot be fully mixed, which may affect the postoperative analgesic effect of the patient and increase the side effects of analgesics. Most of the existing configuration processes are open, and the liquid preparation device and the surrounding environment cannot be guaranteed, increasing the possibility of liquid medicine contamination. The analgesic drug configuration strategy is mostly recorded manually, and there is no systematic automated statistical device, which is not conducive to clinical statistics and the optimization of clinical analgesic pump drug configuration strategy.
