Definitions

  • a mandrel is positioned within the opening in sealing relationship to the bag and a cannula is positioned within the mandrel in communication with the interior of the bag.
  • the cannula projects outwardly away from the bag and a removable cap is positioned over the outwardly projecting portion of the cannula.
  • the present invention is directed to a device of highly simplified design for taking blood samples with a view to performing subsequent analyses.
  • a device in accordance with the invention essentially comprises in combination a bag having a neck, a needle which penetrates into said neck in order to be made integral with the bag and a cap designed to cover said needle.
  • the cap is provided with an internal axial spur which is capable of penetrating into the chamfered mouth of the needle for the purpose of closing olf this latter.
  • the mandrel terminates in a portion of small diameter which projects outside the neck of the bag and over which the mouth of the cap is intended to tit.
  • the invention extends to devices which entail the combination of two or more of the forms of embodiment referred to above.
  • FIG. 1 is a part-sectional plan view of a rst form of embodiment of a device in accordance with the invention.
  • FIG. 2 is a part-sectional plan view of a second form of embodiment.
  • FIG. 3 is a corresponding profile view.
  • the device in accordance with the invention comprises a bag 1 consisting of two plastic sheets sealed along Fice their edges and progressively narrowing as shown in FIG. 2 so as to form a neck 3 in which is inserted a mandrel 4.
  • the needle or cannula 5 is mounted in said mandrel and is covered with a cap 6.
  • the apparatus also consists of a bag 1 having a narrowed end 2 and shaped in the form of a neck 3, a mandrel 4, a needle or cannula 5 and a cap 6 which is adapted to cover said needle and to cooperate with the neck of the bag.
  • the neck 3 of the bag is adapted to close over the mandrel 4 which has in this case a special shape as will be described in detail hereinafter.
  • the bag is preferably formed by bonding together two sheets of a suitable plastic material and more especially, although not exclusively, a polyamide such as, for example, Rilsan (registered trademark),
  • Two sheets of plastic material are bonded along three sides so as to form a border 7 and a sealed portion of greater width is preferably reserved at the small end of the bag opposite to the neck as shown at 8 for the purpose of marking inscriptions thereon such as numerals for production batch identification or indications relating to the liquid which is drawn in at the opposite end; and, as indicated earlier, the bag terminates in a kind of neck 3 into which the mandrel 4 has previously been inserted.
  • Said mandrel consists of a base 9 through which is pierced an axial opening 10 having a diameter which is substantially equal to the internal diameter of the needle, said opening having an extended portion in the form of an axial passage of slightly larger diameter.
  • a needle In this passage is inserted a needle, the heel of which is accordingly brought to bear against the radial shoulder formed in the mandrel by the junction of the two axial passages.
  • the mandrel is provided with a circular groove and terminates in a rib shown at 12.
  • Said rib 12 serves as a shoulder against which the edge of the bag neck is brought to bear.
  • the mandrel then extends outwardly in the form of a portion 13 which may be cylindrical, for example, and over which is tted the cap 6.
  • Said cap 6 accordingly comes into abutment with the annular shoulder which is formed by the rib 12, namely with that face of said shoulder which is opposite to the face against which the bag neck is abuttingly applied.
  • an internal axial spur 14 which, as shown in FIG. 2, can penetrate into the free chamfered end of the needle 5 so as to close ol this latter.
  • the needle 5 is first inserted in the mandrel 4 in such a manner that the heel thereof is abuttingly applied against the annular shoulder of the mandrel, whereupon the mandrel is fitted into the neck of the bag and said mandrel and said neck are nally assembled by heat-sealing.
  • the material which constitutes said neck penetrates into the annular groove 11, said mandrel being thus perfectly secured whilst the needle is consequently made fast with the bag, and the cap is then placed in position.
  • the complete assembly can be sterilized either by suitable heating if this is permitted by the nature of the constituent material or alternatively by any other suitable method, for example by exposure to ultra-violet radiation.
  • the needle When the blood-sampling or drawing operation is cornpleted, the needle is withdrawn from the blood vessel and, during this movement also, any relative displacement of the components of the -apparatus is prevented on the one hand by the base of the mandrel and on the other hand by the groove 11. It is then merely necessary to replace the cap and any desired indications may be marked on the sealed border 8.
  • the device which has just been described accordingly permits the possibility of taking blood either from arteries in which the blood stream is at a certain pressure or from the veins of animals such as, for example, cattle, in which the venous blood also fiows at a certain pressure, or also from the veins of human beings, especially if an artificial venous blood pressure has been created by means of a correctly placed tourniquet.
  • this device is of extremely simple design and therefore particularly easy to manufacture, with the result that the cost price thereof is very low.
  • a large quantity of such devices can therefore be employed for veterinary blood sampling with a view to testing the state of health of entire herds of animals, and each apparatus can be thrown away after it has been used once.
  • a device for taking blood samples comprising:
  • a flexible bag having an opening therein, said bag being made of two sheets of pliant plastic material sealed together around their edges;
  • a mandrel positioned within said opening in sealing relationship with said bag, said mandrel having a bore extending therethrough in communication with the interior of said bag, said bore including first and second portions with said mandrel having an internal radial shoulder positioned at the juncture of said first and second portions;
  • said mandrel further having an annular groove formed in the periphery thereof with the plastic material of said bag penetrating into said groove for interconnecting said mandrel to said bag;
  • a cannula positioned within one of the portions of said bore in free communication with the interior of said bag, said cannula having one end thereof adapted to abut against said radial shoulder and having a portion thereof projecting outwardly away from said bag.
  • a device for taking blood samples comprising:
  • a flexible bag having a reduced neck portion with said I neck portion having an opening therein, said bag being made of two sheets of pliant plastic material sealed together around their edges;
  • a mandrel having a first portion positioned within the opening in said neck portion in sealing relationship with said bag, said mandrel having a bore extending therethrough in communication with the interior of said bag;
  • said mandrel further having a second portion integrally connected to said first portion with said second portion being of larger size than said first portion and said neck portion, said second portion being positioned Within the interior of said bag;
  • a cannula positioned within said bore in free communication with the interior of said bag, said cannula having a portion projecting outwardly away from said bag.
  • a device for taking blood samples comprising:
  • a exible bag having a reduced neck portion containing an opening formed therein, said bag being made of two sheets of pliant plastic material sealed together around their edges;
  • a mandrel positioned within said opening in sealing relationship with said bag, said mandrel having a bore extending therethrough in communication with the interior of said bag;
  • said mandrel having an intermediate portion positioned within and in sealing engagement with the neck portion of said bag, said mandrel having an enlarged base portion integrally connected to one end of said intermediate portion with said base portion being positioned Within the interior of said bag;
  • said mandrel further having yan outwardly projecting portion integrally connected to the other end of said intermediate portion, said outwardly projecting portion having an external radial shoulder adapted to abut against the outer end of said neck portion;
  • the intermediate portion of said mandrel also having a central circular groove formed in the outer periphery thereof with the plastic material of said neck portion penetrating into said groove for securing said mandrel to said bag, said mandrel further having an integral radial shoulder formed therein extending inwardly into said bore;
  • a cannula positioned within said bore in free communication with the interior of said bag, said cannula having one end thereof adapted to abut against said internal radial shoulder, the other end of said cannula projecting outwardly away from said bag and having a chamfered mouth formed thereon;
