Description

Technical Field

[0001] The invention belongs to the field of emergency laboratory medicine, and in particular relates to a medical single-tube air flow receiving box with buffer and air filter. Background Art

[0002] In order to improve the working efficiency of the emergency laboratory, tertiary comprehensive hospitals are generally equipped with various logistics systems to quickly transport blood samples to the laboratory. Among them, samples from the fever clinic are usually transported to the emergency laboratory for testing. The single-tube pneumatic tube logistics is a point-to-point pipeline transportation system. Its advantages are small size, easy installation, rapid transmission, no intermediate transfer points, and low failure rate. It is usually the preferred logistics system for transmitting blood test tubes from the fever clinic to the emergency laboratory. However, due to the particularity of the fever clinic, patients with infectious fever are generally admitted, and their diagnosis and treatment environment is usually seriously polluted, especially airborne pathogens may contaminate the air in the clinic. At this time, using pneumatic tube logistics to transmit blood samples is actually connecting the fever clinic and the emergency laboratory with a pipeline, and continuously transporting polluted air to the emergency laboratory, which will pollute the emergency laboratory. Since the emergency laboratory is usually equipped with a blood collection window to collect blood samples for emergency patients; in this case, emergency patients may be infected with pathogens due to contact with polluted air transported from the fever clinic. In addition, the single-tube pneumatic flow uses gas pressure to blow the test tube from one end of the pipe to the other end. The speed at the pipe outlet is often relatively high. If the test tube speed is not well buffered, the test tube collides with an object or the buffering is insufficient, the blood in the test tube is prone to hemolysis in the violent collision, and the hemolyzed sample will cause inaccurate test results, affecting the patient's diagnosis and treatment. The current single-tube pneumatic flow receiving point usually uses a sponge for buffering. The blood hits the sponge, and the sponge is compressed and buffered for a very short distance. The blood in the test tube is rapidly braked over a short distance, and the red blood cells violently hit the inside of the test tube cover and are easily damaged and hemolyzed. Such short-distance rapid buffering kinetic energy cannot actually meet the sample transportation requirements, resulting in frequent hemolysis in actual work. Hemolysis events can cause deviations in test results, and the general processing requirement is that the patient re-draws blood. In summary, the single-tube pneumatic flow in the emergency laboratory needs to be equipped with a receiving box that can filter contaminated air and can well buffer the kinetic energy of the blood test tube.

It starts when the air pressure increases and automatically closes when the air pressure is lower than the air pressure inside the receiving box. When the single-tube pneumatic flow transports the test tube, the receiving box starts the exhaust fan (43) of the upper air filter (5) and the lower air filter (7), filters the polluted air blown out of the single-tube flow, and enters the filter element from the six outer sides of the upper air filter (5) and the lower air filter (7), filtering the pathogenic microorganisms in the polluted air. The filtered air is drawn out from the central hole of the filter element by the exhaust fan (43); the kinetic energy of the blood test tube is buffered by the silica gel buffer receiving box (6) and slides to the spoon-shaped receiving box (19), and slides along the inclined surface to the bottom of the spoon-shaped receiving box (19), and the bottom of the spoon-shaped receiving box (19) is designed to open the windowed magnetic door (4); then the green light of the illuminated transparent glass window (11) lights up, the upper electromagnet sheet (9) and the lower electromagnet sheet (13) turn off the current, and the windowed magnetic door (4) is released, so that the laboratory staff can safely take out the blood test tube.
