Description

Bag for shipping blood samples and means of closure

sliding safety

in two parts."

  The present invention relates to a bag for shipping blood samples and a two-part sliding safety means. Doctors who take blood samples from their patients but do not have laboratories themselves.for blood testing or can not perform specific blood tests using laboratory facilities at their own facility. provision, must ship these

  blood samples by protecting them against aging

  and breaking into appropriate light bulbs or

  flasks, the shipment being done for example by

  sagers or by mail. The same remark applies equally

  routine calibration and control of automated blood analyzers in specialized laboratories from standardized blood samples made using donor blood. Blood test results only give reliable results if the test is performed as soon as possible after the blood test or if it is ensured that the blood sample has been tested.

  kept in an appropriate state for the necessary duration

  re. In many cases for example during the expedition

  by mail, the duration of transport is relatively long

  such that prior to shipment of the blood samples

  guins, the necessary measures must be taken to ensure that these samples do not change during transport

  that is, so that the temperature of the blood samples

  guins during transport does not exceed the value of

8 C.

The present invention thus has for

  purpose of creating a transport container, simple,

  easily without significant means, and to send blood samples, by post,

  safe way without breaking and protecting against

  temperature, so that even after 24 hours, the temperature inside the transport receptacle

does not exceed 8 C.

Many tests done in the

  framework of the present invention on isolating materials.

  the most diverse types and forms of

  -port most different eg hollow cylinders with lid, as well as shipments of samples

  by mail, have shown that such receptacles do not satisfy

  not to the mechanical conditions of transport, nor to the

thermal insulation conditions.

  Ultimately, the problem posed in the context of the present invention has been solved by a bag of expedition of blood samples consisting of an insulated pouch of foam, fixed, elastic, semi-dry, filled with dry ice, and in the form of a flat piece, one end of which is

  welded and / or closed by gluing, this pocket being made

  It is formed into a thin-walled foam tube with at least one corresponding poly-tubular lining in which appropriate conditions are provided for the blood samples and which consists of small pieces of tube, expanded, juxtaposed and / or respectively glued and / or welded. along their longitudinal axes, the polytubular lining being dimensioned so as to fix in

  the receptacles for the blood samples

  guins and to protect them further against shocks and

pressure effects.

  Preferably, the foam insulation bag consists of a polyurethane, elastic, semi-hard liner made of a thermoplastic material, this lining consisting of an elasticity foam.

  density of less than 50 kg / m3 in particular less than

less than 20 kg / m3.

  According to the invention, the foam insulating bag is preferably obtained from a corresponding foam insulating tube, by crushing one end and welding it. The foam tube preferably has a wall thickness of 10

  and 20 mm and in particular a thickness of 15 mm; its diameter

  The outer surface is preferably between 13 and 15 cm and its length about 40 cm, which gives a ratio between the thickness and the outside diameter of the tube which is less than about 1: 10. After crushing, there is obtained a hollow body having a cavity whose cross section corresponds to an oval or a flattened rectangle whose short sides are in the form of half-circles facing outwards, the longitudinal axes from one rounded to the other corresponding to a length of about 15 at 16 cm and the transverse axes at a length of about 3 to 4 cm. At the closed end by welding, the cavity tapers in wedge form from inside to outside as well as

  the open end that must be closed before shipping.

  The open end may for example be closed by welding or gluing or by engaging the safety closure device, sliding in two parts

  which will be described later, and which also

  The multi-tube liner is composed of foam tube pieces open on both sides and which are juxtaposed by being joined by welds along their long sides. The inside diameter

  pieces of foam tube are chosen in order to receive

  for blood samples. The multi-tube

  longitudinal edges of the insulating foam bag.

In order to be able to fill the internal cavity portions formed by the welds of the foam insulating bag, and which have a wedge shape on both sides, being delimited by the weld beads and by the multi-tube packing and the containers containing the samples of blood, with as much carbon dioxide as possible, the polythene bag filled with dry ice is

  adapted to the shape of these inner cavities.

  These bodies have exactly the same function as the

It is clear that we can also remove these notches 20, because the edges which are then degraded at right angles ensure

  already a function of retaining hooks.

  The U-profile halves 13, 14 may be made of any material. They are preferably made of synthetic material and in particular of a material which makes it possible to manufacture half-sections of U-shaped sections 13, 14 by an injection method. Instead of projecting members 18 in the form of

  retaining hooks, as shown, one can also

  provide other protruding devices similar to
