Infantile endocrine effusion sampling device convenient to use

Abstract

The invention discloses a pediatric endocrine effusion sampling device convenient to use, which comprises a fixing plate, a sampling assembly is arranged at the upper end of the fixing plate, the sampling assembly comprises an effusion cylinder and a piston cylinder, a first end cover is arranged at the upper end of the effusion cylinder, a liquid inlet pipe and an air outlet pipe are arranged on the first end cover in a penetrating manner, and two groups of L-shaped clamping grooves are uniformly formed in a fixing ring on the inner side of the first end cover; a filter frame is arranged below the first end cover, two sets of fixing buckles at the upper end of the filter frame are clamped in two sets of L-shaped clamping grooves, an air inlet one-way valve at the lower end of a piston cylinder is connected with an air outlet pipe, a piston head is arranged in the piston cylinder in a matched mode, and an air outlet one-way valve and a piston rod are arranged on the piston head. The end of the piston rod penetrating through the second end cover is in threaded connection with a palm pad. The extracted accumulated liquid can be filtered and separated through the filter frame, subsequent detection is facilitated, air in the piston cylinder can be prevented from being discharged from the liquid inlet pipe through the air inlet one-way valve and the air outlet one-way valve, continuous sampling of the device is facilitated, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to an easy-to-use sampling device for endocrine effusion in children. Background technique [0002] The endocrine system is an integrated regulatory mechanism that controls and regulates the organism by secreting special chemical substances. In the hospital, in order to thoroughly ascertain the cause and condition of the patient, sometimes it is necessary to extract secretions or pleural effusion from the human body, and use instruments to analyze and test the secretion or pleural effusion, so as to ascertain the cause of the patient and the condition of the patient for convenience. Provide targeted treatment to patients. [0003] For example, the Chinese patent No. 2020208181415 discloses a sampling device for endocrine effusion in children, which includes a sub-frame with openings on the top and one side. The bottom of the connector and the sub-frame is provided with a ...

Problems solved by technology

[0004] Through the analysis of the above patents, it is found that the traditional endocrine effusion sampling device has a simple structure and cannot separate the flowing liquid and mucus in the effusion during use, and after the piston is pulled to sample, the air in the sampling bottle will pass through when the piston is reset. The sampling needle squeezes out the sampling bottle, which is inconvenient for continuous sampling and inconvenient to use
