Description

Technical Field

[0001] The present invention relates to the technical field of infusion equipment, and more particularly to an automatic control infusion device. Background Art

[0002] As an auxiliary tool for medical care and infusion, the infusion stand is indispensable in medical work. At present, medical infusion stands are of various forms, but the purpose is the same, which is to facilitate the infusion of patients. The general infusion stand is a single-pole infusion, and one infusion pole has 2-3 hooks for infusion of 2-3 people. The existing infusion stands generally have only the single function of hanging hanging bottles, and do not have the function of heating the medicine or calling medical staff for fluid replacement. When patients are infused in the cold winter and the temperature in the medical room is low, they often feel uncomfortable due to the low temperature of the medicine. Especially for critically ill patients with very weak constitutions who need special care, the colder temperature of the medicine is injected into the body, which will pose a great safety hazard.

[0003] After searching, the invention patent with Chinese patent number CN201521113926.8 discloses an infusion stand with temperature control function, which includes a base and a bracket. The lower end of the base is provided with universal wheels, the top of the bracket is provided with a hook, and the bracket is arranged on the base. It also includes a heating clamp and a temperature control device. The heating clamp includes a fixing clamp, a heating unit and a temperature transmitter; the temperature control device includes a shell, a temperature adjustment unit, an alarm unit and a manual alarm button. A circuit board is arranged inside the shell, and a signal conditioning circuit, a microcontroller, a power module, a communication interface and a wireless communication module are arranged on the circuit board. According to the different physiques of patients, medical staff can adjust the heating temperature accordingly, and because the temperature control device has a wireless communication module, medical staff can realize remote monitoring of the heating temperature through handheld devices or monitoring computers. Once abnormal temperature is found, action can be taken quickly to ensure the life safety of patients.

[0004] Since the heating clamp and the temperature control device are fixed on the bracket, if the heating clamp and the temperature control device are fixed on the upper side of the bracket, the heating clamp can clamp the upper side of the infusion tube. At this time, the distance between the heating clamp and the patient's infusion arm is large, and the infusion tube between this distance is exposed to the outside. The heated liquid will lose heat during the flow of this section of the infusion tube (especially when the infusion flow rate is slow), which will cause the liquid to cool. The cold liquid is injected into the patient's body, causing discomfort to the patient. If the liquid medicine is heated at a high temperature, although the temperature of the liquid medicine injected into the patient's body can be guaranteed It is gentle, but heating the medicine at a high temperature will destroy the medicinal properties of the medicine. The medicine with destroyed medicinal properties will be injected into the patient's body, which will also cause harm to the patient. If the heating clamp is installed at a suitable position on the lower side of the bracket, the bracket needs to be closer to the patient's arm for infusion. Usually, one bracket is used for infusion by multiple people, resulting in patients who are far away from the bracket being unable to use the heating clamp to heat the liquid inside the infusion tube normally. It is inconvenient to adjust the position of the heating clamp according to the patient's position, and it is also inconvenient to heat the position of the infusion tube close to the patient, which reduces its practicality.
