Definitions

  • the delivery of media in predetermined amounts is known from all areas of technology, medicine, chemistry, etc. As a rule, an exact dosage of the medium is desired.
  • the tolerances to be observed in the dosage are often in the percentage range, which can be ge with the dosage of larger quantities with relatively little technical effort ge guaranteed. When dosing small to very small amounts, however, this represents a technically difficult problem to be solved.
  • the smallest amounts of liquid media are metered, for example, in inkjet printers. These emit approximately four to six picoliters of ink per impulse during the printing process.
  • the next larger metering devices, as they are known spielmik from medical applications, are able to dose amounts of about 0.3 ml.
  • Such a syringe-like device for dosing liquids or pastes is known from DE 91 07 574 U1, in which a housing is provided with an outlet opening. In the housing, a piston is arranged. In the region of the outlet opening, a valve is arranged in front of which a metering chamber is arranged. In the housing, a return spring and an actuating mechanism is provided. The operation of the device by means of a lever.
  • devices are known which work in the manner of a cartridge. The cartridge can be operated via a handle.
  • the known metering devices meet the demands placed on them. However, applications are known in which the quantities are too large; they are only able to dose amounts of 0.3 ml on average. A lower dosage is not possible with these devices. Also, the accuracy of the dispensed per metering amount often leaves something to be desired. Since automatic metering is not possible, the metering techniques known from ink jet printers are not applicable.
  • the object is also achieved in that a circuit is provided in the housing, which actuates a dosing shaft with the interposition of a motor and possibly a transmission (If, for example, a stepping motor is used, no transmission is required).
  • This also provides a device for metering the smallest amounts of liquid or pasty media as well as filler-containing or reactive media with busy processing time, which allows extremely high accuracy for quantities of from 0.01 to 200 .mu.l, preferably from 0.1 to 20 .mu.l, to dose. Due to the motor design of the device also the ease of use for each user is significantly increased.
  • FIG. 2 is a plan view of the device shown in FIG. 1; FIG.
  • FIG. 5 shows a longitudinal section through a Luer lock exchange cap with dispensing needle.

  • the cap 19 also has a circumferential latching nose 192, which is followed by a thread 193. The cap 19 is screwed to the thread 182 and 14, respectively.
  • the metering shaft 2 is guided in the bore 11 of the housing 1. It extends almost over the entire length of the bore 11 and thus also the entire length of the housing 1. Spaced to its end, the metering shaft 2 is widened in diameter. In this area, it is provided with an external thread 22, which corresponds to the internal thread 14 of the housing 1.
  • the shaft 2 has a longitudinal groove into which a feather key 23 is inserted. In the assembled state of the metering shaft 2, the feather key 23 is in the region of the longitudinal groove 17 of the housing 1. In its region facing the rotary knob 5, the shaft 2 is guided in the bore 131 of the web 13.
  • the translation shaft 3 which surrounds the metering shaft 2 in sections, is made of plastic in the embodiment. However, other materials are equally useful, spielmik aluminum, brass, metal or ceramic.
  • the translation wave has a substantially rotationally symmetrical design.
  • the translation shaft 3 is penetrated by a bore with which it is pushed onto the metering shaft 2.
  • the bore has a sou ⁇ usual longitudinal groove 32 which receives the key 23 in the assembled state.
  • a positive connection in the radial direction between metering shaft 2 and translation shaft 3 is caused.
  • the translation shaft 3 is slidably disposed along the metering shaft 2.
  • a stud can be used, which engages in the keyway ein ⁇ .
  • a pulley 36 is disposed on the translation shaft 3, on which the compression spring 4 is supported in the assembled state. The disk 36 serves as wear protection for the translation shaft 3.
  • the knob 5 is provided with a blind hole 51, with which the knob 5 is pressed onto the metering shaft 2. Markings 52 are mounted on the rotary knob 5, by means of which the immersion depth of the rotary knob 5 in the housing 1 can be read.
  • the dispensing needle 6 is formed slightly angled in the embodiment. This training offers the possibility of better adaptation to the particular application. In addition, the accessibility is improved by the angled dispensing needle 6.
  • the inner diameter of the dispensing needle is selectable depending on the particular application.
  • the dispensing needle 6 has a reservoir 61 which is formed in the manner of a plastic cap.
  • the supply container 61 tapers in the direction of the dispensing needle 6.
  • the storage container 61 is provided with webs 62 with which the container 61 can be attached to the cap 19 of the housing 1 by overcoming the locking nose 192 and can be screwed with the help of thread 193.
  • the dispensing needle 6 is designed as a disposable part. This proves to be particularly advantageous when processing reactive media with limited (short) processing time.
  • the screw-on connection with the housing 1 makes it possible to easily assemble and disassemble the dispensing needle 6, including the storage container 61.
  • the control knob 8 is provided on its side facing the housing 1 with a Sacklochboh ⁇ tion, in which a bolt 81 is screwed. On the thread also a slider 82 is screwed, which is T-shaped in cross-section. Due to the T-shaped Aus ⁇ formation is between the outer ends of the slider 82 and the housing 1 zuwand- th side of the control knob 8, a gap whose clear width substantially corresponds to the wall thickness of the housing 1 in the region of the longitudinal groove 17. The control knob 8 is guided in this way by the longitudinal groove 17.
  • the bolt 81 projects beyond the slider 82 on its side facing away from the control knob 8. The protruding beyond the slider 82 part of the bolt 82 is guided in the assembled state in the feed groove 33 and the return or Frei ⁇ grooves of the translation shaft 3.
  • the medium to be metered is first introduced into the reservoir 61.
  • the dispensing needle 6 is then attached to the cap 19 and screwed.
  • the Dosie ⁇ tion itself by moving the control knob 8 in the following manner: If the Particular ⁇ knob 8 along the longitudinal groove 17 in the direction of the outlet opening 12 moves, guided in the conveying groove 33 of the translation shaft 3 end of the bolt 81 along the feed groove 33rd As a result of the movement of the control knob 8 in the longitudinal direction of the housing 1, the translation shaft 3 is set in rotation as a result of the alignment of the conveying groove 33 which is not parallel to the longitudinal center line of the device. The rotation of the translation shaft 3 is transmitted to the metering shaft 2 due to the positive connection between the translation shaft 3 and the metering shaft 2.
  • the return of the control knob 8 is in its initial position. This is done by simply retracting the control knob 8. Due to the return groove 35 provided in the translatory shaft 3, the control knob 8 is returned to the starting position without rotation of the translatory shaft 3 and thus without rotation of the metering shaft 2. The metering shaft 2 persists in their position. This prevents that when returning the dienknopfes 8 in the starting position, the tip of the dosing 2 retracts from the reservoir 61, which could lead to trapped air or the like in the reservoir 61 and could adversely affect the following dosage.
  • control knob 8 has reached its starting position, a new dosing process can be started. Since the metering shaft 2 has exactly the same position at the beginning of this new metering operation as at the end of the preceding procedure, a loss-free new metering operation is made possible in exactly the same narrow tolerance range.
  • the metering shaft 2 is turned back with the aid of the rotary knob 5.
  • the freewheel groove 34 thereby removes the operating knob 8 from the engagement of the conveying movements (forward or reverse spiral), so that the metering shaft 2 in the thread can be turned back to the head without the operating knob 8 having to follow the linear movements in a guide.
  • the marking 52 indicates to the operator the number of dosing operations already carried out.
  • the shaft 2 is rotated and immersed in the Vor ⁇ storage container 61 a.
  • the button 5 pressed with the shaft 2 dips into the blind hole 16. Due to the uniformly provided markings 52, whose distance from one another is adapted to the particular stroke determined by the thread, the user can read off the number of strokes / dosing operations. Since, in the dosing operations, the shaft 2 dips further and further into the reservoir 61 in accordance with its stroke, the markings 52 gradually dive into the blind hole 16.
  • a hole may be provided in the knob 5, through which an extended version of the metering shaft 2 passes. In this case, the markings provided on the shaft are inserted into the knob 5 at each stroke.
  • the Aus ⁇ leadership example according to the figures 6 to 8 can be actuated by a motor.
