Definitions

  • the present 'invention relates in general to a device for pumpinguids, semi-iluids, and syr-y upy, pulverous or other substances, and more particularly hasreference to a pumping device- 5 including a tube made of elastic material which. ⁇
  • the pumping mechanism is mounted upon -a base forming a casing provided with a removable bottom, intended to contain the accessories utilized in the operation of the device, so that they will be always within reach of the operator.
  • Another characteristic of the device consists in the use of a single wide roller of large diameter. which acts upon a loop of the tube, positioned in a. suitable casing. The free ends of the said tube,l are connected 4to suction and compressionv conduits, respectively. Due to this particular arrangement, a chamber oi' large volume is obtained, and all churning of the blood or of other substance passing through the tube is avoided, the deformation of the tube being produced progressively over a long section thereof.
  • a third characteristic of this device -resides in thecontrol of the single roller mentioned above, by means of a crank or other suitable member for revolving it indifferently in both directions, or inl one direction only, this latter possibility preventing all false movements, which is extremely-importantin the case of blood transfusion.
  • the said control member is, besides. combined with a hodometer to measure the output oi the pump in direct relation to the number Aof revolutions of the rotor which supports the roller.
  • the device also includes means associated with the single roller mentioned above to vary the spacing of the rollerfrom the side of the casing which serves-as a bearing surface for the deiormation ofthe tube, so as to'permit the use of tubes of various sections.
  • the casing containing the mechanism has amovable part,vcombined with a play compensating device, which permits, when it is separated and drawn apart from the ilxed part, the tube to be veasily placed in position without having to touch its ends, or to bring them into contact with any part of the apparatus. As a consequence these ends are not exposed to the risk of being soiled or contaminated and the apparatusl may ⁇ be utilized" without any previous aseptic treatment.
  • Figure l isa perspective view ofthe appara-' 5; tus, the cover being removed and the parts of the' apparatusjbeing separated to permit placing th elastictube in position.
  • Figure y2 is al view cl'tvrrespondin,r to Figure 1,'
  • Figure 3 is a plan view seen Vfrom above the apparatus, with a parttorn awayg'to-show the de vice which ensures the irreversibility of the control member.
  • Figure 4 is a sectional view ⁇ along line A-B 'of Figureii.
  • Figure 5 is a plan-viewseen from "above rthe apparatus, the mechanism actingon thetube L being removed.
  • Figure 6 is a side elevationlshowing the appa'-v ratus in working position.
  • i Figure 'l is a view correspondingto Figurev 6, but with the hand crank turned upside down. '-1
  • Figure 8v is a detailed view showing the parts yof 25' the casing, separated to-permit'placing the elastic tube in position.
  • y 'I'he apparatus of the present invention vis mounted-on a hollow base I provided with a ⁇ re movable bottom 2 which serves as a-receptacle 30 for the accessories requiredforuse ofthe-appa# rams.
  • Y Mounted on base is a block 3 provided with a-cylindrical chamber 3 which serves as the casing of the pumping mechanism.
  • V ⁇ It wm be noted 35 that an opening 2lil is formed in one side o1' block 3 providing access tothe chamber 3 ⁇ and that this same side of the block 3 is provided with grooves 22 and 24 and two smalli'urrows' Il.
  • the purpose of theopening 20 and groovesfwill 40 be described hereinafter.r -f
  • a pinion 38 is affixed on the upper end of axle I2 and is rotated to desired positions by a cooperating worm 35 mounted in boss II.
  • Block ⁇ I8 is pro-4 vided with two grooves 2
  • Each -shaft, 4,1 has an eccentric pin 48 on the free end thereof loosely positioned in a groove 48, provided in the ⁇ bossesl I4 and I5 of block. It can be conceived, therefore, that when double lever 25 is swung from the closed position las shown in Figures-2 and 6, to its opened position as shown in Figures land 8, pins 48 cause slidingv block I8 to slide inthe direction of arrow f. l f
  • shafts 41 upon which the ends of this double lever are clamped, are engaged in long holes provided for them in the ends of the said double lever.
  • Trobe 28 is placed in empty space 3I with its ring 33 set in furrow- 34.andafter having been passed through passage 58, it is formed into a loop 55 ( Figure 1) of the same diameter as casing 3' /which contains it. Itis then made to passthrough'pasSa-Ge 54, andv led voutfof the apparatus through thegfree part of empty space 3 I, ring- 32 being at the same ⁇ time engaged Vin thecorresponding furrow 34'..
  • Double lever 25 is then swung forward to its closed position thus drawing together-blocks ⁇ I8-and 3, and enclosing partsof tube 28 inthe channels formed by grooves 2I and 22, and 23-24 '(Flgures 2, 6 and 7) v 4 kBy acting upon crank -I0,roller I8-isA displaced along thelength of loop 55 v which it deforms against the sides ofcasing 3'. .
  • This deformation produces compression of the fluid in the portion of the tube toward which the roller advances, and
  • the lower portion of plate 8 ⁇ carries an eccentric 28' which has aconnecting rod 28; associated therewith forV actuating-'the hodometerg21.
  • the hodometer receives an impulse through connection' 28-28 and, as explained above, provides.
