Microorganism analytical sampling device

Abstract

The invention discloses a microorganism analytical sampling device. The microorganism analytical sampling device comprises a cup-shaped body with the open upper end; an opening of the cup-shaped body is provided with a cover body; the cover body is matched with the opening of the cup-shaped body in size and shape; the bottom of the cup-shaped body is arranged into a funnel-shaped cup bottom; the middle of the funnel-shaped cup bottom is provided with a bottom end through hole; a bottom filter film is arranged below the bottom end through hole. According to the microorganism analytical sampling device, the structure is reasonably improved, the funnel-shaped cup bottom is matched with the bottom filter film particularly, and accordingly sputum can be conveniently sampled through the microorganism analytical sampling device without special air extraction device and accordingly the operation is convenient, the medical staff is well protected, and the significance on the sampling of dangerous bacteria such as tubercle bacilli is important.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sampling device for conveniently analyzing microorganisms in various samples such as sputum and body fluid. Background technique [0002] In the clinical treatment process, it is necessary to use the sputum extraction device to extract the patient's sputum for testing. For example, patients with tuberculosis can test their bacterial composition by sampling sputum. Specifically, the patient spits out the sputum into the sputum extractor for re-sampling. For example, the patent document No. 201020015085.8 discloses a sputum extractor, which consists of an oral isolation sleeve, a sputum suction tube, a sputum bottle, an air suction tube, and a negative pressure ball. The mouth of the sputum bottle is plugged with a stopper, and the stopper of the sputum bottle is inserted into the inlet end of the suction tube, and the outlet end of the suction tube is connected to the negative p...

Specifically, the patient spits out the sputum into the sputum extractor for re-sampling. For example, the patent document No. 201020015085.8 discloses a sputum extractor, which consists of an oral isolation sleeve, a sputum suction tube, a sputum bottle, an air suction tube, and a negative pressure ball. The mouth of the sputum bottle is plugged with a stopper, and the stopper of the sputum bottle is inserted into the inlet end of the suction pipe, and the outlet end of the suction pipe is connected with a negative pressure ball, and one side of the negative pressure ball is provided with a one-way air valve; the mouth is isolated The surface of the sleeve is smooth, and the inner end is bent down. The size and shape of the inner opening of the inner end matches the throat opening at the upper end of the patient's trachea. There is a sputum suction tube inside the oral isolation sleeve. One end of the suction tube is connected to the inner opening, and the other end is inserted into the sputum bottle. Inside, a sampling cup is provided at the bottom of the sputum bottle, and an earring is provided on the upper mouth of the sampling cup. The other end of the sputum suction tube is inserted into the sampling cup at the bottom of the sputum bottle by the plug of the sputum bottle. The negative pressure ball in the sputum bottle is directly connected to the sputum bottle, which may easily cause sputum to enter the negative pressure ball, causing the negative pressure ball to be polluted and the function to fail, affecting the normal use of the device and reducing the service life
