Definitions

  • This invention relates to instruments for the taking of blood and for injection.
  • the present invention concerns an instrument of this kind which obviates the aforesaid disadvantages.
  • a ball preferably made of glass, the diameter of which is greater than that of the orifice of the said rubber tube, so as to stretch the tube on its inside and thus ensure closure thereof, the closing effect being easily eliminated, at the moment of piercing, by simple external squeezing of the said rubber tube, between the fingers, opposite the ball.
  • This squeezing produces in effect, a deformation of the rubber and causes the rubber to slip on the ball, thereby creating two lateral passages around the ball.
  • the rubber tube which provides the connection between the test-glass and the needle-carrying tube, may be formed, opposite the position' of the ball situated within it, with two opposite enlarged or flat parts, on which the fingers are to be placed, to ensure and facilitate the squeezing of the rubber tube.
  • the invention consequently covers, as a new industrial product, any sterile instrument for the aseptic taking of blood or injection, in which the closure and temporary opening of the communication between the test-glass and the needlecarrying tube is obtained in the manner herein described.
  • Figure 1 is a part-sectional view of the instrument
  • Figure 2 is, on a larger scale, a longitudinal section of the rubber tube in its ball-receiving part
  • Figures 3 and 4 are, on the same enlarged scale, two cross-sections on the line 3-3 of Figure 2 and show respectively the tube in shut-off and open positions.
  • I denotes the testglass
  • 2 denotes the rubber tube which is securely mounted thereon by an end-piece 3 also of rubber and integral therewith
  • 4 is a glass tube which is mounted at the end of the tube 2 and in which is sealed the needle 5 covered by the protecting cap 6.
  • the tube 2 is normally straight when the device is held in inclined position or, in other words, is semi-rigid so that the device may be readily manipulated with one hand.
  • a, ball I Inserted within the tube 2 is a, ball I which is preferably made of glass and the diameter of which is greater than that of the orifice of the said tube, so as to stretch the tube on its inside by the elastic expansion of the rubber.
  • the arrangement thus ensures the closure-of the tube 2 by eliminating all communication between the test-glass, inside which a vacuum has been previously created, and the needle-carrying tube.
  • the aforesaid rubber tube 2 comprises on the outside opposite the ball 1, two fiat parts 8 which are 180 apart.
  • test glass In order to remove theneedle from the blood filled test glass after the blood taking is terminated, it is sufficient to break the tube 4 after filing at y--y.
  • the test glass may be sent to a laboratory for analysis under perfectly sterile conditions without it being necessary for it to be accompanied by the needle and associated end of the tube 4.
  • a syringe or the like instrument for medical purposes comprising an ampule, syringe needle, a straight tube of an elastic material secured to the open end of the ampule and the rear end of the needle, respectively, said tube forming a straight, fluid type, semi-rigid connection between said ampule and needle and having part of its length exposed for grasping by the fingers of the operator, and a ball of rigid material having a diameter in excess of the inner diameter of said tube and being seated in the exposed part of the latter, whereby pressure of the operators fingers on the ball creates a temporary deformation of said tube, to increase its inner diameter at right angles to the direction of the pressure and to provide passages for a fluid past the ball.
