Abstract

1,077,157. Blood transfusion device. J. RAZIMBAUD. July 12, 1965 [July 10, 1964], No. 29395/65. Heading A5R. A blood transfusion or perfusion device comprises a blood storage receptacle having a piercable wall, a dispensing receptacle for blood drawn therefrom having a needle attached to and in communication with its interior, and a housing for the piercing end of the needle, rigidly attached to the storage receptacle, and slidably attached to the dispensing receptacle so that axial movement of the receptacles relative to each other causes the needle to pierce the storage receptacle. The device is typically illustrated by Fig. 2, wherein the needle housing 1 is closed by a piercable membrane 4, this face being affixed to a storage receptacle at 5. The narrow portion 3 of the housing widens to a skirt 2, which is mounted in an annular recess 6 in an upper extension 7 of the dispensing receptacle 8. Two diametrically opposing lugs 10 on the skirt engage in cam slots in the outer wall of the recess, each slot having a horizontal part 12 followed by a vertical part 13, an inclined part 14 and another horizontal .part 15. The needle 17 is attached within a central bore 16, and enters the interior of the dispensing receptacle 9. The other end of this receptacle is closed by a cap 22, which may carry a blood filter 25, and is suitably connected, via 23, to a flexible tube and cannula. The skirt may further be sealed, and its attachment to the receptacle 8 lubricated, by bactericidally impregnated viscous material at 21. By rotation of the blood storage receptacle, the attached needle housing rotates relative to the dispensing receptacle, and the lugs move out of portion 12 of the slots to unlock the members. Axial movement of the housing 1 towards the dispensing receptacle 8, the lugs moving in portion 13 acting as a guide, causes the needle to pierce the storage receptacle, when blood flows through the needle into the dispensing receptacle. Further axial and then rotational movement brings the lugs into portion 15 of the slots, thus locking the members in the operating position.

Another advantage of this embodiment resides in the fact that it avoids any risk of deformation of the constituent elements of the apparatus and that it allows to ensure them a perfect seal. 4 The apparatus according to the invention comprises a movable element provided with a thin bottom ensuring the closure of a bottle or a container dis-posed above this bottom and which contains the liquid to be infused or transfuse, this movable element being associated with a hollow part forming the chamber of the apparatus and inwhichdébouche the lower end of a perforation needle of the bottom of the movable element, this aiguillont the upper part is engaged in thismobile element being maintained in an upper extension of the hollow part forming the chamber of the apparatus. The invention also extends to embodiments having at least one of the following characteristics: va) The lower part of the movable element which is associated with the hollow part forming the chamber of the apparatus is arranged in order to ensure a perfect seal during movements of this element intended to cause the perforation of its thin bottom and to give great flexibility to these movements. b) The chamber of the apparatus comprises in the upper part means for guiding the mobile element. c) This room is provided at its lower part with a removable bottom for connecting it to the ai-guille injection, the removable bottom may include a filter element.

The following description made with regard to the annexed drawing given by way of non-limiting example will make it possible to better understand the invention.

In this drawing

Figure I shows, in an external view, an improved apparatus for perfusion and transfusionsanguine according to the invention.

Figure 2 is a sectional view along line II-II of Figure I.

FIG. 3 is a sectional view along the line III - III of FIG. 2. The apparatus shown comprises a flexible element I constituted by a hollow body 2 open at its lower part and topped with a further portion. small diameter3 closed to 2/3 of its height by a low-thick bottom 4 on which is fixed by welding the container 5 con-tenant · liquid to be infused or transfused. The parts - 4 2 and 5 constituting the movable element I which affect here a cylindrical shape could just as well be of polygonal shape. The movable element I s 1 engages in an annular recess 6 made in the upper extension7 of a cylindrical or polygonal body 8 provided with a cavity 9 forming the chamber of the apparatus. the hollow body 2 is provided at its lower part with two diametrically opposed cylindrical lugs 10 (see FIG. 5) and which are intended to cooperate with two grooves II, each having a horizontal portion 12 connected to a vertical part 15 which meshes with a inclined portion 14 itself to a horizontal part 1 5. the upper extension 7 of the cylindrical body 8 is provided with a central bore 16 intended to allow the fixing by gluing or welding, an ai-guille 17 whose lower part opens into the cavity 9 forming the chamber of the apparatus and whose upper part is engaged in the movable element I.
