The British "Natural Biomedical Engineering" magazine recently published a new online report, said the United States scientists have developed a new device similar to the "microscopic tube maze", just a drop of blood can quickly detect sepsis. This test method is fast, cheap, and accurate, making it easy to monitor patients at risk of sepsis.

Sepsis is a fatal disease. When pathogenic bacteria or conditional bacteria invade the blood circulation and grow, the patient's body will respond extremely to serious infections and cause tissue and organ damage. However, according to statistics, about 30% of patients will be misdiagnosed. This is because the specificity of human detection methods at the present stage is poor and slow. It takes several days to produce results, causing doctors to prescribe unnecessary antibiotics. Causes the proliferation of antibiotic resistant strains.

In this regard, Daniel Elimia, a scientist at the Massachusetts General Hospital, and his colleagues designed a new detection device. They dropped a drop of blood into a "maze" device consisting of microscopic tubes, and then used a machine learning algorithm to correlate the movement of neutrophils in the maze with the severity of sepsis. Neutrophils have chemotaxis, phagocytosis, and bactericidal effects and are at the forefront of the body's invasion of microbial pathogens, as are the "first-aid workers" of the immune system. Through its special association with sepsis, the device can calculate a "sepsis score."

The researchers showed that the test takes only a few hours, and in a double-blind observational study of 42 patients, healthy individuals can be distinguished from patients with sepsis based on sepsis scores, with a sensitivity and specificity of more than 95%.

At present, the method needs to be validated by a larger and more diverse group of patients, but the researchers said that this new result still has the potential to improve the survival rate of patients at high risk of sepsis, while reducing the overuse of antibiotics. .

Improvements in microscopy make it more difficult for cells to escape the doctor’s eyes. It can be expected that there will be more sophisticated machine eyes in the future, which will help us to understand the truth. Until then, no matter whether it is a mysterious pathogen, an irritable immune cell, or a tumor cell, it will be promptly controlled without accidentally injuring the healthy body. It's great.

Semi-closed Grinding Table

1. Product description:

Semi-colsed downdraft grinding table is used for the collection of dust generated during grinding, polishing, deburring, etc. It has bottom and side suction holes to extract dust at source. The baffles on two sides form a semi-close space to prevent dust from spreading.

6. Central Fume Extraction System

1) Cantilever type fume extraction system

Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the Suction Hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

2) Hood suction type fume extraction system

The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length.

The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

3) Room tupe fume extraction system

Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing.

For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean.

The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals.

4) Blow suction type fume extraction system

Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops.
