Description

Technical Field

[0001] The utility model discloses an intelligent automatic dressing-changing infusion stand, which belongs to the field of automation and the technical field of medical equipment and is specifically applied to infusion management at the medical clinical frontline. Background Art

[0002] Infusion therapy is widely used in the medical clinical frontline in the current global medical industry. Infusion equipment is an essential basic consumable for every medical institution. Doctors usually prescribe multiple bottles of medicine at a time when using infusion therapy, and the hospital has a large number of infusion patients. The whole process of dispensing, inserting needles, applying medicine, changing dressings and removing needles depends entirely on the hospital nurses. When the patient has blood reflux, the nurse needs to spend a lot of time and energy to deal with it before changing the dressing. If the operation is improper, air will enter the infusion device. This situation can easily cause air thrombosis and endanger the patient's life and health. And an intelligent infusion stand that can automatically replace infusion bottles is particularly important. In response to the above problems, the utility model has developed an intelligent automatic dressing change infusion stand. It can ensure the continuity of the infusion process and automatically replace empty medicine bottles, thereby reducing the workload of medical staff, improving work efficiency, and reducing the possibility of human errors. This type of equipment is particularly suitable for departments or patients with large infusion demands and frequent changes. It can greatly improve the safety and convenience of infusion therapy, ensure that patients receive more stable and continuous treatment, and thus improve treatment outcomes and patient satisfaction. Summary of the invention

[0003] Although traditional infusion stands can also hang multiple bottles of liquid medicine at a time, each dressing change requires timely operation by hospital nurses. If the dressing is not changed in time, blood reflux is likely to occur. Dealing with these problems will not only consume a lot of energy and time of nurses, but also easily cause air thrombosis if improperly operated, endangering the life and health of patients. In view of the existing problems, the utility model has developed an intelligent automatic dressing change infusion stand, which can hang four bottles of liquid medicine at a time, and is suitable for various types and specifications of infusion bottles and infusion bags commonly used in medical places. After the nurse hangs the liquid medicine required for the patient's treatment in sequence and gives the patient a needle, until all the liquid medicine placed on the infusion stand is infused, the process of detecting the flow rate in the middle - pulling out the infusion set - changing the medicine bottle - inserting the infusion set - detecting the flow rate is completely completed by the machine. The continuity, timeliness and safety of the infusion process are ensured, and the empty medicine bottle is automatically replaced, thereby reducing the workload of medical staff, improving work efficiency, and reducing the possibility of human errors. The safety and convenience of infusion therapy can be greatly improved, thereby improving the treatment effect and patient satisfaction.
