    • PROBLEM TO BE SOLVED: To obtain an underwater water sampler by which a plural kinds of water samples can be obtained, even from places with different depths in one loading and collecting operation. SOLUTION: In an underwater water sampler, an underwater pump 9 is connected to an airtight container 1 in which a plurality of water sampling bags 3A, 3B,... composed of a flexible film are housed and which communicates with the outside via a container opening and closing implement 5, and sampling tubes 6A, 6B,... which are connected to the respective water sampling bags 3A, 3B,... communicate with the outside via respective sampling opening and closing implements 4A, 4B,.... Then, before the underwater pump 9 is operated, the container opening and closing implement 5 is closed, and at least one out of the sampling opening and closing implements 4A, 4B,... is opened. In synchronization with the operation stop of the underwater pump 9, the container opening and closing implement 5 is opened, and the sampling opening and closing implements 4A, 4B,... are closed.

    • PROBLEM TO BE SOLVED: To collect blood samples of a fixed quantity by repeatedly performing pressure reduction and opening to the air on an airtight space formed below a container placed on the outlet side of a sample collecting needle and setting the pressure reducing time within a range in which the collected amount of blood becomes proportional to time from the suction starting time, and then, setting the opening time at the period until the internal pressure of the space returns to the atmospheric pressure after space is opened to the air. SOLUTION: When a blood-collecting tube 16 is inserted into a coupler 14 from the above and continuously pressed down, the coupler 12 tightly comes into contact with a sampling container 18 and an airtight space is formed below a blood-collecting needle. A suction pump 46 reduces the internal pressure of the space and an open valve 42 opens the space to the air. A control section 50 controls the pump 46 and valve 42 and is provided with a timer A which controls the pressure reducing time and the airtight space opening time and another timer B which controls the elapsed time from the sampling starting time. Therefore, samples of a fixed quantity are collected by repeating basic steps of pressure reduction and opening to the air on the space by setting the pressure reducing time within a range within which the collected amount of blood becomes proportional to the elapsed time from the suction starting time and the airtight space opening time to the period from the opening time to the time at which the internal pressure of the space returns to the atmospheric pressure.
