Embodiment Construction

[0010] figure 1 and figure 2 The evacuation device 1 shown in is arranged with its device housing 2 on a table 3 . Here, it is ensured that the stop edge 4 of the device casing 2 placed on the front of the workbench 3 is positioned accurately, so that the vacuum device 1 does not need to use fixing screws and / or clips. As an alternative and / or supplement, the vacuum device 1 can also be mounted on a non-slip base of the workbench 3 .

[0011] The introduction receptacle 6 for receiving the blood extraction tubule 5 to be evacuated consists of an introduction funnel 7a. In this embodiment, the introduction funnel is integrally formed with the central receiving member 7b. The introduction socket 6 is arranged obliquely in the device housing 2 from the lower end to the upper end, that is, from the outer end to the inner end. This inclination allows the sample 8 to remain as far as possible in the region of the bottom end of the blood aspiration tubule 5, as indicated by the ...

Abstract

A vacuum-pumping device (1, 100) for generating vacuum in a bloodletting small tube (5) comprises a casing (2) containing a vacuum pump (13) and a pressure measuring instrument electrically connected to the vacuum pump (13). The vacuum pump has a needle connected by a tube (12). The needle breaks through a tube diaphragm (11) due to the plug-on of the bloodletting small tube (5) into an introduction admission (6; 106), characterized that the introduction admission (6; 106) moves from a from bottom to top rising inclination in the equipment casing (2) and returns, after completion of the evacuation procedure during or after taking the bloodletting small tube (5) out by a force (F), preferably by a spring, into an initial position.

Description

technical field [0001] The invention relates to a vacuum device for generating a vacuum in a blood-drawing tubule, the device comprising a vacuum pump and a pressure measuring device electrically connected to the vacuum pump in a housing of the device, the vacuum pump having a suction tube connected through a catheter A needle pierces the orifice membrane when the blood aspiration tubule is inserted into the introduction adapter. Background technique [0002] DE2908817A1 discloses such a vacuum pumping device for the blood drainage system, which is suitable for generating a vacuum in the blood pumping small tubes before use or at the time of use, such as the vacuum pumping at the beginning of the day. Meet the needs of the day. The vacuuming device has a hollow air pumping needle in the device shell, which is connected with a vacuum pump driven by an electric motor through a conduit with a pressure measuring device. The aspiration needle is surrounded by an introduction fu...
