ZLG's embedded solutions for medical and prevention equipment

Abstract: ZLG has been deeply engaged in embedded systems for 20 years and has provided embedded solutions for many medical enterprise users, including medical ventilators, medical equipment disinfection cabinets, respiratory pumps and other common medical equipment. This article introduces various embedded solutions provided by ZLG for medical care and prevention equipment.

Medical ventilator

In the current extraordinary period, the frontline troops are in need of ventilators. As an effective means of artificially replacing the spontaneous ventilation function, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and they occupy a very important position in the field of modern medicine. Ventilators are a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the lives of patients, as shown below.

ZLG can provide the Cortex-A9 display control solution - M6708 for such applications. Combined with the ZLG open source GUI engine, the application interface can be quickly developed, as shown below.

The series platform has the following advantages:

Support AWTK open source GUI engine for rapid development of user interfaces;

Rich multimedia interfaces, including camera, HDMI and other interfaces, can easily realize image acquisition and media display;

Powerful codec functions integrate 1080P video codec, 2D/3D image acceleration and other powerful multimedia codec functions, which can process multimedia files easily and smoothly.

Medical equipment disinfection cabinet

Medical equipment disinfection cabinet refers to a tool that sterilizes, disinfects, keeps warm and dehumidifies medical equipment, surgical equipment, towels, clothing, tableware, medical facilities and other items through ultraviolet rays, far infrared rays, high temperature (high temperature disinfection through heating tubes), ozone and other methods. For example, it can sterilize, disinfect, keep warm and dehumidify medical equipment such as tongue depressors, oral mirrors, thermometers, stethoscopes and other medical equipment that are used very frequently, as shown below.

In order to prevent these instruments from being contaminated by various bacteria and viruses, and further avoid possible cross infection between patients and patients, and patients and doctors, timely disinfection and sterilization are needed to prevent the spread and infection of these medical-induced diseases. Conventional disinfection cabinets basically require manual operation and control, which will consume a lot of working time of medical staff and have a high error rate. For example, it is necessary to manually open or check the switches of each electric pump and electric valve, etc., and it is impossible to timely understand the real-time status of the disinfection cabinet. Therefore, even if the disinfection cabinet fails, it cannot be known in time, which is obviously not in place for the safety protection of the disinfection cabinet.

Nowadays, there are automatic medical device disinfection cabinets that solve the above problems. They can realize intelligent control of the disinfection cabinet, save medical staff's time, and can be monitored remotely. ZLG can provide Cortex-A9 master control solution - M6708 for such applications, as shown below.

The series platform has the following advantages:

Cortex-A9 quad-core processor, clocked at up to 1GHz, with 1G DDR3, 4G eMMC;

Provides WIFI, 4G, ZigBee and other wireless solutions, which can be expanded through MiniPcie according to actual conditions;

A variety of expansion interfaces are reserved, including network port, RS-485, camera and other interfaces.

Infusion Pump

Infusion pumps are usually mechanical or electronic control devices that control the infusion rate by acting on the infusion catheter. They are often used in situations where the infusion volume and drug dosage need to be strictly controlled, such as when using pressor drugs, antiarrhythmic drugs, intravenous infusion of infants or intravenous anesthesia. The following is a discussion of the issues that should be paid attention to in the daily operation, maintenance and preservation of infusion pumps in combination with clinical practical applications, as shown below.

ZLG Embedded Solutions for Medical Testing and Protection Equipment

Abstract: Detection kit testing is currently the key means to diagnose suspected patients. This article introduces the solutions provided by ZLG in the key instruments during the development of the test kit.

The development of virus test kits is inseparable from the analysis of medical instruments such as gene amplification instruments (PCR) and fluorescence analyzers. After the successful development of the reagents, three samples of suspected patients' nasopharyngeal swabs, sputum, and alveolar lavage fluid need to be tested. The detection of the test kits also requires corresponding instrument support, including medical equipment such as specific protein analyzers and handheld fluorescence analyzers. Under the needs of a large range of testing groups, there will be a demand for miniaturization of such equipment. In the best case, handheld analysis is achieved to achieve point-of-care testing (PCOT).

ZLG's mature application solutions have been widely used in such equipment and instruments. This article will introduce ZLG's solutions in equipment and instruments.

Gene Amplifier

The polymerase chain reaction (PCR) is actually a programmable, fast-changing, and precisely temperature-controlled temperature cycler, which is mainly used for gene separation, cloning, and nucleic acid sequence analysis. It plays a vital role in obtaining the full genome sequence of the new coronavirus due to its high sensitivity, simple operation, and time-saving characteristics.

The block diagram of the gene thermal cycler (PCR) system is roughly as follows, which mainly includes the display communication control board, the control system main control board and the power supply. ZLG mainly provides the Cortex-A7 platform display control solution for the gene thermal cycler - M6Y2C, industrial control core board, and passes strict EMC and high and low temperature tests to ensure that the core board is stable in harsh environments to ensure the stability and reliability of the display.

The series platform has the following advantages:

Equipped with industrial-grade large-capacity eMMC and TF card;

It has rich interface resources, including 8-way UART, 2-way isolated CAN-bus, 1-way isolated RS-485, 1-way USB Host and other wired data communication interfaces.

Handheld/Benchtop Fluorescence Analyzer

Fluorescent immunoassay analyzers are used for in vitro testing in hospitals, mainly for testing human serum/plasma/whole blood/urine samples, to assist in the diagnosis of myocardial injury, heart failure, acute coronary syndrome, cardiovascular inflammation, venous thromboembolism, routine inflammation, identification of bacterial/viral infections, early detection and treatment of acute and chronic kidney disease and other diseases.

The fluorescence analyzer mainly includes two control platforms: PC and ARM master control.
