A dual-channel automatic infusion pump and its control method

Abstract

The invention discloses a dual-channel automatic infusion pump, which is characterized by comprising: a pump door and a pump body; an infusion device with an infusion tube clip installed inside the pump body, wherein the infusion tube clip comprises a first hole groove and a second A hole groove, the first infusion pipe passes through the first hole groove, and the second infusion pipe passes through the second hole groove; the infusion detection device is matched with the first infusion pipe and the second infusion pipe, and is used to detect the first infusion pipe or the second infusion pipe. Whether the bag of liquid connected to the second infusion tube has completed infusion; a dual-channel switching mechanism for driving the infusion tube clamp to switch the first infusion tube and the second infusion tube between the conduction state and the stop state; wherein When it is detected that a bag of liquid connected to the first infusion tube has completed the infusion, the dual-channel switching mechanism drives the infusion tube clamp, so that the first infusion tube is switched from the conduction state to the liquid stop state, and the second infusion tube is stopped from the stop state. The liquid state is switched to the conducting state, so as to automatically switch to a bag of liquid connected to the second infusion tube for infusion. Through the embodiment of the present invention, the infusion operation of two or more bags of medicinal liquid can be automatically completed after one 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 an automatic infusion pump and an implementation method thereof. Background technique [0002] At present, in the process of implementing infusion therapy in hospitals, there are often not only one bag of liquid medicine, but two bags of liquid medicine. However, the current infusion pump products on the market can only access one bag of liquid medicine at a time. The conventional operation is: after the first bag of liquid medicine is infused, the medical staff must change the liquid medicine, and then reset the setting according to the new liquid medicine. parameters, etc., which is time-consuming and labor-intensive, and also increases additional operational risks. [0003] In the process of clinical liquid treatment, there is a common need for continuous de...

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.
