Description

drip micro controller

technical field

The utility model relates to a micro-volume controller, in particular to a drip micro-controller used for connecting drip bags to achieve simple, convenient and precise control of liquid transmission. the

Background technique

In general medical practice, injecting the liquid in the drip bag into the human body requires rigorous calculations. Too much or too little may cause harm. At present, there is a serious shortage of nursing staff, and there is often a nursing staff who needs to take care of 10 people. ~The workload of more than 20 beds, plus the working hours of the nursing staff are often more than 10 hours, so medical disputes emerge in endlessly, and the medical behavior of drip delivery is often the easiest Neglected, but it also takes up a considerable amount of time for nursing staff. the

When the drip is in progress, the nursing staff needs to confirm whether the drip bag has been dripped, and also need to confirm the drip flow rate and time. If intermittent drug administration is required, the overall burden on the nursing staff will be increased, and the risk will also increase. Substantially improved. Generally speaking, the drip can control the flow rate, but it cannot remind the nursing staff when the drip is finished, and it cannot automatically set the dosage each time. Undoubtedly, it is necessary to improve. the

At present, there is a peristaltic pump 9 on the market, also known as a drip pump, which can also be used for quantitative drug delivery. In operation, when the peristaltic pump 9 is driven by external power to rotate, the hose 91 is squeezed by the roller 92 to produce deformation, and when it turns to the outlet port 93, the pressure is released, so that the liquid in the hose 91 flows out, but the peristaltic pump 9 will have the following problems:

1. After the hose is compressed, its pressure accumulation will cause pulse pressure when it is released, and when it is transported to the human body, it will easily cause discomfort.

2. The dosage will be limited by the diameter of the hose and its compression space, so the control margin of the dosage is limited. the

3. After the hose is squeezed, it is easy to break, so the service life is short. the

4. The structure is complex and expensive. the

5. It needs to use motor as power source, which increases the cost. the

6. The hose is made of special material and cannot be directly applied to the standard hose of the medical unit, which will increase the cost of consumables. the

Generally, the volume of drip bags can be divided into 250ml, 400ml, 500ml, and 1000ml, but not all of them need to be delivered at one time, and continuous delivery is not the best way for patients. Therefore, if a specific amount of fluid can be injected at a specific time, It can also overcome the shortcomings of commercially available peristaltic pumps, and has more commercial value and overall medical contribution. the

In addition, if the nursing staff meets the doctor’s prescription for infusion of 450ml, the nursing staff will first leak 50ml of the 500ml drip bag, and then give the patient the volume of fluid, so there will be a waste of medicine and increase the working time The problem. the

Another example is Taiwan's new patent M404020, an active drip injection device, including a casing, a flow control system, a drip bag, and a rotating pressure head, and the flow control system includes a flow controller, a control circuit, and a peristaltic pump. And a power cord, its working principle is through the action of the peristaltic pump, driving the rotating pressure head to rotate and squeeze a drip tube filled with liquid, so as to continuously and quantitatively make the fluid in the drip tube flow forward, With the use of low-pulse pump head, the requirement of high-precision flow rate can be achieved; however, the above-mentioned problems and shortcomings will occur when using this peristaltic pump. the

The reason is that, in view of this, the inventor researches and improves the existing peristaltic pump, and provides a drip micro-controller to achieve higher value. the
