Nutrition pump and flow control method

Abstract

The invention discloses a nutrition pump and a control method thereof. Switching of nutrient solution and cleaning solution can be realized by the aid of a liquid exchange valve; by continuous enteral nutrition feeding, stomach and esophagus discomfort can be effectively reduced, nutrition support can be provided for patients limited in absorption ability to the greatest extent, and enteral nutrition clinical treatment effects are improved. Structural simplicity, low cost and effectiveness are realized. Since the liquid exchange valve is arranged on the nutrition pump instead of a catheter, discarding of the liquid exchange valve in replacement of the catheter is avoided, reusability of the liquid exchange valve is realized, and processing difficulty and cost of infusion catheters are reduced. By adoption of a rotary encoder, equipment parameters can be quickly set, and convenience in use is achieved. A quick mounting seat is structurally reasonable and compact, the size of a fixing seat is reduced, and convenience in mounting and demounting is achieved. By direct injection molding of a fixing block on a pump body, extra mounting steps are reduced, operation efficiency is improved, and suitableness for popularization is realized.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a nutrition pump and a flow control method thereof. Background technique [0002] In the prior art, the current medical pump is a medical injection device, including micro injection pumps, micro infusion pumps, hydraulic pumps and the like. Most of them are used to accurately, evenly and continuously pump liquid medicine or other substances needed by the human body into the body. The medical pump is easy to operate, timing and quantitative, and the concentration and speed of the substance can be adjusted at any time according to the needs of the disease. The use of medical pumps to rescue critically ill patients can reduce the workload of nurses, improve work efficiency, and cooperate with doctors accurately, safely and effectively. For those who cannot swallow or have difficulty swallowing, they generally need the assistance of a nutritional pump to achieve the purpose of abso...

AI Technical Summary

Problems solved by technology

However, the nutritional pumps on the market can basically only pump one substance into the nutrition bag at the same time, and cannot freely control the conduction state of the catheter, let alone pump the substances in two bags at the same time, especially for those who need to replenish liquid substances For humans, the use efficiency is low, and the requirements cannot be quickly met, which is not conducive to speeding up the recovery of patients' physical fitness

[0003] In addition, in traditional liquid flow control devices, the operation interface is mostly in the form of buttons to control the amount of liquid input.

There are shortcomings in this method, that is, the function is single, the operation is inconvenient, and it is prone to fatigue failure

At the same time, the structure of the auxiliary suspension fixing device in the suspension process of the existing medical pump is large and complicated, and it is troublesome to disassemble.
