Abstract: @ A syringe for collecting a sample of blood or another liquid comprises a syringe cylinder and a piston arranged displaceably therein. One or more axially extending recesses are formed in the inner wall of the syringe cylinder axially spaced from the inner end thereof. The recess or recesses contain a material which is pervious to gas and impervious to liquid, such as a hydrofobic material, a hydrophilic material with capillary effect, or a material which swells when contacted by liquid. The sample collecting chamber within the cylinder may be vented to the atmosphere by placing the piston in the recessed area of the cylinder. Arterial blood may then pass into the syringe under arterial blood pressure, and the flow of blood into the syringe is automatically stopped when the sample collecting chamber of the syringe has been filled, because blood cannot pass the liquid impervious material arranged in the recesses. The axial innermost portion of the inner cylinder wall, which is not recessed, may co-operate with the piston in a conventional manner so as to provide a suction effect within the blood collecting chamber, if desired.

Abstract: A liquid sampler which may be used for collecting samples of arterial blood is preferably in the form of a syringe. A venting passage (25, 31) is defined in the syringe piston (12) so that gas may escape through the venting passage when arterial blood flows into the cylinder space (17) under the influence of the arterial blood pressure. The venting passage is controlled by valve means (19,21), which automatically close the venting passage when the cylinder space has been filled with blood and the blood starts flowing into the venting passage. The venting passage is closed by liquid resistant valve surface parts, and movement of these surface parts to their closing position is caused by a liquid reacting substance (22) which is exposed to the liquid sample flowing into the venting passage. This liquid reacting substance may, for example, be a material which swells, expands, or is softened when contacted by liquid. Alternatively, the liquid reacting substance may be a liquid soluble material.

Abstract: @ A syringe for collecting blood samples, especially arterial blood samples, comprises a syringe cylinder (11) and a piston assembly (12) displaceably arranged therein. The piston assembly defines a venting passage (25, 37, 31) through which gas or air may escape when arterial blood flows into the cylinder space (17) under the influence of the arterial blood pressure. The venting passage is controlled by valve means (23, 31), which may selectively and reversably be opened and closed independently of axial displacement of the piston assembly. The valve means may, for example, be operated by rotating a piston rod through a predetermined angle or by means of a valve actuating lever (35), which is biased towards a position in which the valve means are closed, and which may be tilted to an open position by depressing a finger grip (36) positioned at the free outer end of the piston rod (32).

Abstract: ©7 A liquid sampling device (10), in particular intended for arterial blood sampling and blood gas analysis, is disclosed. The sampling device is provided with valve means (20, 21, 22) which in the dry state permits expulsion of gas from the sampler reservoir (18), but which automatically closes on contact with blood. The valve means comprises cooperating valve surface parts (21, 26) retained apart by a dry gas permeable material (22), which collapses on contact with a liquid, thereby moving the valve means to their closed position.
