Double-channel automatic infusion pump and control method thereof

Abstract

The invention discloses a double-channel automatic infusion pump. The double-channel automatic infusion pump is characterized by comprising a pump door, a pump body, an infusion apparatus, an infusiondetection device and a double-channel switching mechanism, wherein the infusion apparatus is mounted in the pump body and provided with an infusion tube clamp, the infusion tube clamp comprises a first hole groove and a second hole groove, a first infusion tube penetrates through the first hole groove, and a second infusion tube penetrates through the second hole groove; the infusion detection device cooperates with the first infusion tube and the second infusion tube and is used for detecting whether infusion of a bag of liquid connected with the first infusion tube or the second infusion tube is completed or not; the double-channel switching mechanism is used for driving the infusion tube clamp to switch the first infusion tube and the second infusion tube between a conducting state anda liquid stopping state; and when the situation that infusion of a bag of liquid connected with the first infusion tube is completed, the double-channel switching mechanism drives the infusion tube clamp, so that the first infusion tube is switched to the liquid stopping state from the conducting state, the second infusion tube is switched to the conducting state from the liquid stopping state, and infusion of the bag of liquid connected with the second infusion tube is automatically switched. Through the embodiment of the invention, the infusion operation of two or more bags of medicinal liquid is automatically completed after one-time access.

Description

technical field [0001] The invention relates to the field of infusion sets, in particular to a dual-channel automatic infusion pump and a control method thereof, in particular to a dual-channel switching mechanism of the automatic infusion pump and its implementation. Background technique [0002] In the process of carrying out transfusion therapy in current hospitals, there is often not only one bag of medicinal liquid, but two bags of medicinal liquid are in the majority. However, the current infusion pump products on the market can only receive one bag of medicine at a time. The conventional operation is: after the first bag of medicine is infused, the medicine must be changed by the medical staff, and then reset according to the new medicine. Parameters, etc., are time-consuming and labor-intensive, and also increase additional operational risks. [0003] In the process of clinical liquid therapy, there is a general need for continuous delivery of multiple bags / bottles ...

Problems solved by technology

However, the current infusion pump products on the market can only receive one bag of medicine at a time. The conventional operation is: after the first bag of medicine is infused, the medicine must be changed by the medical staff, and then reset according to the new medicine. parameters, etc., which is time-consuming and laborious, and also increases additional operational risks

[0003] In the process of clinical liquid therapy, there is a general need for continuous delivery of multiple bags / bottles of liquid medicine for infusion, because the small-capacity medicine container is used for large-capacity infusion, or another kind of medicine is added during the infusion; the infusion pump is used to carry out The current solutions for infusion include: 1. Manual replacement. After infusing a bag of liquid, the alarm prompts the medical staff to set and install the next bag of liquid at the bedside; the disadvantages are low efficiency, heavy workload of medical staff, and interruption of infusion The time is relatively long; 2. Multi-pump switching, multiple infusion pumps are installed in advance and the infusion parameters are set, and the relay infusion mode is set through the communication connection. After one infusion pump completes a bag of liquid infusion, it will automatically start the next infusion The pump starts infusion; the disadvantage is that multiple infusion pumps need to be used together, occupying too much equipment, and relying on external communication networks poses safety and reliability risks; 3. Consumable switching, similar to piggyback / secondary infusion The infusion mode uses special consumables and completes the automatic continuous infusion switch through the liquid level difference between the two bags of liquid; the disadvantage is that when the second bag of liquid starts infusion, the medical staff needs to open the stopper pulley at the bedside to start, which increases the workload of the medical staff ;The end time of the infusion of the second bag of liquid cannot be monitored, and it cannot be controlled when the infusion speed of the two bags of liquid is different; a one-way valve is required on the main infusion line, the cost of consumables is high, and there is a permeation string in the one-way valve when the infusion time is long Liquid condition, contaminate another bag of liquid medicine

If the liquid level difference between the two bags of liquid is not operated properly, the second bag of liquid cannot be completely infused, or even the infusion of the second bag of liquid cannot be started, and the therapeutic effect will not be achieved.
