Definitions
- the pan is mounted on a rocking arm pivotally supported on the beam and rocked about an axis extending along the beam by a motor mounted on the beam.
- the present invention relates generally to equipment used when taking blood from a donor, and more particularly to apparatus intended to permit measurement of the amount of blood taken in this way.
- equipment of this type comprises a bag, which is usually flexible and which is connected by a pipe to a venous puncture needle, an this bag contains in advance an anticoagulant intended to prevent coagulation of the blood entering the bag.
- Some of these devices are simple spring balances on which the blood bag is suspended during the taking of the blood. Devices of this kind do not make it possible for any agitation of the bag to be effected simultaneously, for the purpose of the above-mentioned mixing.
- An object of the present invention is to provide a balance for a blood bag which is exempt from these disadvantages.
- a balance for weighing and agitating a bloodbag comprises a beam pivotally mounted on a frame, a weighing counterweight adjustably mounted on the beam on one side of the pivot axis, and a pan or other support for a blood bag mounted on the beam on the other side of said pivot axis, the said pan being carried by an oscillating arm which is arranged to be rocked on the beam by a drive unit carried by the beam in order to impart oscillatory movement to the said oscillating arm.
- a knife or other abutment member I which is movable in response to tilting movement of the beam, in order to nip the tube filling the bag when sufficient weight of blood has passed into the bag.
- the device in an advantageous manner effects systematic mixing of the blood taken with the anticoagulant contained in the bag receiving the blood, accurate weighing of the later, automatic interruption of the supply of blood when a determined amount of blood has been taken, and if necessary a warning may be given to the staff supervising the taking of the blood.
- FIG. 1 is a view in elevation of a balance according to the invention, certain of the casing elements protecting the balance having been at least partially removed;
- FIG. 8 is a view of this alternative similar to FIG. 7, at the end of a weighing operation
- FIGS. 9 and 10 are views respectively similar to FIGS. 7 and 8 and relate to'another modified embodiment. I
- a balance comprises a base 10 on which there is fastened a U-shaped yoke l 1 for pivotally supporting a beam 12.
- This beam 12 comprises a cylindrical rod 13 which passes through a rectangular pivot block 14 and is keyed on the latter by a pointed screw 15.
- a pivot pin 16 passes through the pivot block 14, extending transverse to the rod 13, and pivots in the two arms of the yoke 11.
- On the pivot block 14 there are also attached on the one hand a control finger 17 arranged to control a microswitch 18 carried by the base 10, and on the other hand a knife 19 the purpose of which will be indicated hereinbelow.
- a counterweight 20 which will be referred to hereinafter as a weighing counterweight.
- this stop device 21 has a releasable catch mechanism for example a ball 22 acted on by a spring 23, and is arranged to co-operate with reference marks 24 provided along the rod 13; for the sake of greater clarity in the drawing the depth of the reference mark 24 visible in FIG. 1 has been exaggerated. In this way, the stop device 21 can be moved in steps to a required position along the rod 13.
- the rod 13 carries a plate 25 on which there is fixed a frame 26 composed of a sole 27 and two side plates 28A, 28B perpendicular to the sole 27.
- a casing 29 (FIG. 1) is attached to the frame 26.
- the side plate 28A of the frame 26 carries on the outside a micromotor 30 on the output shaft 31 of which there is keyed a connecting rod 32 disposed inside the side plates 28A, 28B of the frame 26. At its free end this connecting rod 32 is articulated to a crank 33 which in turn is articulated at 34 on a rocking arm 35.
- This rocking arm 35 is mounted pivotally by a pin I 36 on the side plates 28A, 28B of the frame 26 and it carries a pan 40.
- this pan is part-cylindrical in shape and on the inside has at least one fastening hook 41 for attaching a blood bag.
- the micromotor 30, the connecting rod 31, and the crank 32 together form a drive unit adapted to apply to the rocking arm 35, and therefore to the pan 40 carried by the latter, alternating oscillations of about 30 for example on each side of a middle position in which the pan is horizontal.
- the beam 12 is provided with a second rod 42 parallel to the rod 13 over part of the length of the latter.
- this rod 42 is carried by a plate 43 connected to the rod 13, and at its other end it is engaged in a hole 44 in the knife 19.
- a counterweight 45 hereinafter referred to as the adjusting counterweight, is mounted slidably on the rod 42.
- a stop device of the type described above, or any similar detent device, may be fastened on this adjusting counterweight 45, making it possible for its position on the rod 42 to be temporarily locked.
- the rod 42 is preferably provided for the purpose with reference marks.
- the knife 19 carried by the pivot block 14 has a foot 37 engaged in said block and an overhung head 38 supported by said foot 37.
- the yoke 11, the pivot block 14, and the microswitch 18 are positioned inside a protective casing 46.
- the latter has two side plates 47, one of which has been removed in FIG. 1. These side plates are carried by the base perpendicularly to the latter and are adapted to be connected by a removable casing 48 provided with apertures for the passage of the rods13 and 42 of the beam 12, and also for the passage of the knife 19; in addition, the ends of the pivot pin 16 of the beam 12 are engaged in the side plates 47.
- pilot lights 50 mounted on the protective casing 46 are pilot lights 50, 51 the purpose of which will be seen hereinbelow, and also a tube support 52 disposed vertically in line with the head 38 of the knife 19.
- This tube support 52 is formed by a plate 55 and at least one elastically deformable retaining claw 56.
- the microswitch 18 is connected in the electrical supply system of the pilot lamps 50 and 51, in the electrical supply ofthc micromotor 30, and also in the electrical supply system of any warning or alarm device provided, for example a bell.
- the finger 17 controlling the microswitch 18 is at a distance from the latter.
- a blood bag 60 is placed in the pan 40 of the balance (FIG. 3), the supply tube 61 connecting said bag to a venous puncture needle (not shown) being passed into the tube support 52 (FIG. 5) below the claw 56.
- the weight of the blood bag 60 is then balanced, taking into account the anticoagulant contained in it, and then with the aid of the weighing counterweight 20 the required weight of blood to be taken is set in advance FIG. 3; in order to do this the stop device 21 is set at the reference mark on the rod 13 which corresponds to the required weight of blood, and the counterweight 20 is moved so as to bear against this stop device 21.
- One electricity supply to the balance is then switched on.
- the operation of taking blood can then be carried out.
- the blood enters the bag 60 it is intimately mixed with the anticoagulant contained in said bag, because of the agitating movement applied to the latter.
- the beam 12 of the balance tends to recover its horizontal equilibrium.
- the knife 19 crushes the tube 61 (FIG. 6) and thus terminates the operation of taking blood which is being carried out.
- the control finger 17 operates the microswitch 18, which extinguishes the pilot light 50, 51 which was in operation and lights up the other, for example a red light, and at the same time stops the micromotor 30.
- This pilot light may be associated with a warning means, such as a bell,-which is operated at the same time as this pilot light lights up.
- the knife 19 is separate from the beam 12.
- this knife is movable axially in the casing 46 and is subjected to the action of a spring 65 .which urges the nipping head of the knife in the direction of the tube support 52.
- This spring 65 is interposed between an annular shoulder 66 of the foot 37 of the knife 19 and the sole of a stirrup 67 fixed to the base 10.
- the knife 19 forms a kind of catch and for this purpose is provided with a notch 68 with which a trigger device 69 is adapted to co-operate.
- This trigger device is pivoted at 70 on the stirrup 67 and is acted on by a torsion spring 71 which urges it inthe direction of the knife 19.
- the trigger device is controlled by the pivot block 14 of the beam 12.
- the trigger device 69 Before a weighing operation (FIG. 7) the trigger device 69 is in engagement with the notch 68 on the knife 19 and the latter is thus held in the upper position not restricting flow through the tube 61.
- the block 14 forces the trigger 69 to disengage the notch 68 and thus to release the catch constituted by the knife 19.
- the latter when thus freed, is returned to the bottom position by the spring 65 and, as previously, crushes the tube 61 engaged in the tube support 52.
- the knife 19 is provided with a projecting stud 72. Consequently, when the right hand side of the beam 12 is raised, the rod 13 comes into contact with the stud 72 on the knife 19 and moves the latter into the upper position. Simultaneously, the trigger 69 disengages from the pivot block 14 and under the action of this return spring 71 comes into engagement with the notch 68 on the knife '19, so as to hold the latter in the raised position.
- the knife 19 is formed as an extension of the movable core 75 of an electromagnet 76, the electrical supply of which is controlled by the microswitch 18 (not shown in FIGS. 9 and Before a weighing operation (FIG. 9) this electrical supply is interrupted and the knife 19 is raised. At the end of the weighing (FIG. 10) the microswitch 18 supplies voltage to the electromagnet 76 and the latter returns the knife 19 in the downward direction in order to crush a tube 61 engaged in the tube support 52.
- the rod 42 of the beam 12 is fixed to the knife 19.
- this rod 42 may be fixed to any part rigidly connected to the rod 13, such as for example the pivot block 14.
- the rods 13 and 42 may form the two opposite limbs of a U-shaped member.
