Modular bedside blood purification equipment and control method thereof

Abstract

The invention provides modular bedside blood purification equipment and a control method thereof. The modular bedside blood purification equipment comprises a blood purification device, an instrumentmain support, a liquid support, a retransfusion detector, a waste liquid support, a first filter support, a second filter support and a liquid support hook, wherein the blood purification device is connected with a fixed base through the instrument main support, the liquid support is arranged on the fixed base, and the retransfusion detector, the waste liquid support, the first filter support, thesecond filter support and the liquid support hook are all arranged on the liquid support. The bedside blood purification equipment has the beneficial effect that the bedside blood purification equipment and accessories thereof are improved. Firstly, a sub-pump is arranged on the blood purification equipment in a modular mode, the blood purification modes under various conditions can be dealt withthrough different combination modes, and meanwhile the operation method is improved; and compared with existing integrated equipment, the modular bedside blood purification equipment has the advantages that operation links of prompting, previewing, self-checking and the like which need to be provided in an installation module are added for a modular operation program.

Description

technical field [0001] The invention relates to the field of medical equipment, and more specifically relates to a modular bedside blood purification device and a control method thereof. Background technique [0002] There are many types of clinically common blood purification machines, such as Braun, Baxter, Fresenius, Asahi Kasei, Junken and other mainstream brands. There are two types of machine design ideas, one is based on the weighing system to accurately control the liquid balance, which includes the single liquid weighing system combination led by Baxter and the comprehensive weighing liquid balance system led by Braun. The other is based on the design idea of ​​measuring pots to control liquid balance, represented by Japan Junken. [0003] The blood purification machines in the market all adopt an integrated design, so the number of pumps on the equipment directly limits the treatment modes it can carry out, and it often seems stretched in the face of more and more...

AI Technical Summary

Problems solved by technology

[0003] The blood purification machines in the market all adopt an integrated design, so the number of pumps on the equipment directly limits the treatment modes it can carry out, and it often seems stretched in the face of more and more complex blood purification modes in clinical practice

[0004] There are several key components on the bedside blood purification machine, which are the air detection and exhaust device and the pressure monitoring device. The air discharge cannot be separated from the venous pot. In clinical practice, the cup-shaped venous pot is more common, and the exhaust effect is good, but Thrombosis is easy to form, and the problem of anticoagulation has always troubled clinicians

Baxter (formerly Jinbao)'s unique patented intravenous pot has good anti-thrombosis ability but has no filter, and there is a risk of micro-thrombosis entering the human body

[0005] Although the weighing system is commonly used, it is easily disturbed by external factors

In addition, the accuracy of the weighing system is directly related to the safety of liquid balance, so the blood purification machine based on the weighing system cannot be used for direct connection with patients for transfer

[0006] The pressure monitoring of most blood purification devices is a direct pressure measurement method in which the pipeline is connected to the pressure sensor. There is also a membrane-type pressure monitoring device headed by Baxter. The former has little interference but the relatively open pipeline is not conducive to sensory control management; the latter It is closed, but the pressure monitoring is conducted through the closed air between the membrane and the sensor. Since the air will seep into the liquid under pressure, there is a problem of inaccurate measurement results.
