Description

Automatic change infusion container and intelligent speed governing's supplementary infusion system

Technical Field

The utility model relates to the field of medical instruments, in particular to an auxiliary infusion system capable of automatically replacing an infusion container and intelligently adjusting the infusion speed.

Background

The current hospital infusion modes generally adopt the following steps:

firstly, an infusion support is generally adopted, a plurality of bottles of liquid medicine can be hung on the support, but medical staff must disinfect and change bottles, monitor manually, and inform the medical staff to treat each bottle when the bottle is finished.

And secondly, an infusion peristaltic pump is adopted in part of environments, a plurality of bottles of liquid medicine can be hung on the support, but the bottles must be replaced through manual disinfection, the infusion peristaltic pump controls the speed and monitors the infusion process, and medical staff are informed to come and handle when each bottle is finished.

As for the two modes, the medical staff need to pay attention to the speed of infusion and change the infusion container all the time, the workload and the working strength of the medical staff can be increased, a certain discomfort is brought to the patient during infusion, and the contradiction between doctors and patients is increased.

And thirdly, a bottle automatic changing mode, for example, Chinese patent CN 107519555A discloses a medical automatic bottle changing device, which independently opens the flow ports in different liquid separating cavities in sequence through a control piece, only one flow port is opened at the same time, namely, only one liquid medicine in a medicine bottle can be input into a vein through a transfer cavity. When the liquid medicine in one liquid medicine bottle is completely infused, the control piece automatically replaces the liquid medicine in the other liquid medicine bottle and infuses the liquid medicine into the vein through the transit cavity until all the liquid medicine in the medical bottle is completely infused. The defects of the patent are as follows: the device and infusion set are integrated, and each infusion requires replacement of the entire set, which adds additional cost to both the hospital and the patient. The control part of the device is naturally controlled mainly by the buoyancy of a valve floating ball inside the bottle head and the acting force of the elastic traction ropes, the buoyancy can be influenced by different medicine densities, and the elastic traction ropes can also cause the front and back sequence confusion and medicine mixed loading due to the blocking and pulling effects of the elastic traction ropes under the influence of environment and temperature, thereby causing the medical accidents of infusion. And thirdly, the device can only contain three bottles at most in single infusion, the requirement of more than three bottles cannot be met or the structure of the device is complex, the automatic bottle changing function cannot be guaranteed, and the cost is greatly increased. And (IV) the device can not detect and automatically control the transfusion speed.

Chinese patent CN 203710457U discloses a multifunctional infusion pump, during infusion, a pump door is opened, an infusion tube passes through an infusion tube fixing clamping groove, a peristaltic box and a liquid stopping clamp in sequence, the infusion tube extends out from the bottom end of the infusion pump, then the pump door is closed, and the infusion process is controlled and detected through external keys and a screen. The defects of the patent are as follows: the infusion pump depends on the working principle of the peristaltic pump, and the peristaltic pump can generate liquid suck-back at the releasing moment because the rotating wheel needs to be alternately released in the pumping process, so that the discharged liquid is suddenly reduced, the pulse delivered by the peristaltic pump can be caused, and blood return and discomfort of a patient can be caused in the infusion process. The infusion pump can normally infuse fluid only by continuously working at high speed by the peristaltic pump, certain decibel noise can be caused, and certain interference is caused to the quiet environment required by a patient. And thirdly, the peristaltic pump piece continuously extrudes the disposable infusion set pipeline, so that the risk of damaging leaked liquid is caused. The infusion pump can only detect and control the function of a single bottle, cannot meet the function of automatically changing bottles when a plurality of bottles exist, and cannot reduce the workload of medical staff.

Accordingly, there is a need to provide an infusion device that is capable of automatic bottle exchange and overcomes the aforementioned problems.
