Title:
LIQUID SPECIMEN SAMPLING DEVICE USED IN OPERATION
Document Type and Number:
WIPO Patent Application WO/2023/134183
Kind Code:
A1
Abstract:
A liquid specimen sampling device used in an operation, related to the technical field of sampling devices. The sampling device comprises a negative pressure suction tip (1), an auxiliary tube (2) connected to the side wall of the negative pressure suction tip (1), and a sampling bottle (3) connected to the auxiliary tube (2). A rebound-type connecting plate (5) is provided at a joint between the negative pressure suction tip (1) and the auxiliary tube (2). A press switch is provided on the side wall of the negative pressure suction tip (2). The diameter of the auxiliary tube (2) is greater than that of the negative pressure suction tip (1). The press switch is an elastic membrane switch (4). When the elastic membrane switch (4) is pressed, a flexible membrane on the elastic membrane switch (4) moves in the direction of the rebound-type connecting plate (5) and is used for blocking the flow of liquid and driving the rebound-type connecting plate (5) to open, such that the auxiliary tube (2) is communicated with the negative pressure suction tip (1). When the elastic membrane switch is released, the flexible membrane restores to the original position, the liquid flows in the negative-pressure suction tip (1), the rebound-type connecting plate (5) returns to the original position, and the auxiliary tube (2) is not communicated with the negative-pressure suction tip (1).
