- volumetric pumps In medical technology, the use of volumetric pumps is known. In such pumps, the pressure force of peristaltic makes a significant contribution to the delivery accuracy. It is therefore necessary to adjust the pressure force of the peristalsis as precisely as possible. In known pumps, such an adjustment of the pressure force of the peristaltic is possible only in a disassembled or opened state of the pump housing. Due to the assembly-related position tolerances of the individual components arising during reassembly of the pump, the achievable accuracy of adjustment of such pumps is limited. Object of the present invention is therefore a pump mechanism with higher
- volumetric pump 1 for conveying media through a flexible hose 2 according to a preferred embodiment of the invention. More specifically, it is an infusion tube pump, which can supply or supply a means of action from an agent reservoir (not shown) at a predetermined delivery rate via an infusion line to a patient.
- the volumetric pump 1 basically has a door 3
- the flexible hose 2 is arranged between the door 3 and the housing 4.
- the hose 2 is provided between a displacement device 5 arranged in the housing 4 and an abutment section 6 formed by the door 3, the abutment section 6 forming an abutment to a contact pressure generated by the displacement device 5.
- volumetric pump 1 is designed as a slide peristalsis mechanism. As such, it has a number of (peristaltic) sliders 8 (here twelve) which are in a slide housing 9 are mounted linearly movable. The slides 8 are driven by an eccentric shaft 10, which has a number of slides 8 corresponding number of eccentric cam 10.1, which are each arranged corresponding to a slider 8.
- the eccentric cam 10.1 of the illustrated eccentric shaft 10 are each offset by 30 ° relative to the respective adjacent eccentric cam 10.1, so that, in a driven by a motor 1 1 rotation of the eccentric shaft 10, by the eccentric cam 10.1 in their
- Linear movement forcibly guided slide 8 promote a volume in a conveying direction in a substantially sinusoidal displacement movement.
- the slide housing 9 is fixedly arranged on the pump housing 4 in order to allow the most accurate possible guidance of the slide 8.
- the slide housing 9 is formed as a separate housing (inner body), which is advantageously attached to the pump housing 4 (outer body) positively and / or non-positively. In the example shown, the attachment of the
- Slider housing 9 on the housing 4 by means of pressed pin.
- all conventional fastening methods are considered, for example by means of other fastening means such as screws, a positive connection or a press or welded connection.
- the slider housing 9 may also be formed as a stoffein Glaiger portion of the housing 4.
- Both slider housing 9 and the abutment portion 6 are thus set in the illustrated voiumetric pump with respect to the pump housing 4.
- the adjustable pressure force of the peristaltic slide 8 relative to the abutment portion 6 is consequently realized via the mounting of the eccentric shaft 10. This is the
- the eccentric shaft 10 is pivotable relative to the slider housing 9 via a pendulum arm 9.1 mounted on a slider housing hinge 9.2.
- the pendulum arm 9.1 is biased by means of the adjustable biasing means 7 such that the eccentric shaft 10 rotatably mounted on the pendulum arm 9.1 is urged in the direction of the abutment portion 6 (see Fig .. 1). Accordingly, those of the Eccentric shaft 10 positively driven slide 8 a force application, corresponding to the biasing force of the biasing device. 7
- the biasing means 7 in the illustrated preferred embodiment as (in this case, three-part)
- Displacement device 5 as adjustable pressure-loaded spring formed between a boom 9.4 of the valve body 9 and a
- Jib 9.5 of the pendulum arm 9.1 is tensioned to bias the eccentric shaft in the direction of the abutment portion.
- the pretensioning device is arranged essentially transversely to the sliding direction of the peristaltic slides 8.
- the biasing means 7 thus generates a torque about the axis of rotation of the slide housing hinge 9.2, about which the pendulum arm 9.1 is pivotable, which is opposite to the torque generated by the pressing force of the peristaltic valve 8.
- the vertical orientation of the biasing direction and the sliding direction of the peristaltic slide 8 relative to each other has the advantage that the distance to the pump housing 4 in the transverse direction to the sliding direction is shorter than in the sliding direction or in tube loading direction.
- volumetric pump housings are generally cuboid and have the shortest edge length in a direction transverse to the sliding direction and to the tube loading direction (usually the vertical direction).
- the accessibility of the adjustable pretensioning device 7 can be improved from outside the housing 4 by such a structural design, since a smaller distance must be bridged.
- Markers 14 are provided, which the user with an increase or
- Reduction of the pressure force of the peristaltic indicate the corresponding direction of rotation.
- the biasing device 7 formed here as a spring adjustment is constructed in three parts from an adjusting screw 7.1, a spring element (wave spring) 7.2 and a spring retainer 7.3 (retaining ring).
- the adjusting screw is, as can be seen in Figure 3, rotatably mounted on the boom 9.4 of the slide housing 9 and the boom 9.5 of the pendulum arm 9.1.
- the spring holder 7.2 acts via an internal thread with an external thread of
- Adjusting screw 7.1 together and thus proceeds in a rotational movement of the adjusting screw 7.1 relative to this in the axial direction.
- the spring holder 7.2 also acts in such a form-fitting manner with the slide housing 9 that this is secured against rotation or co-rotation with the adjusting screw 7.1 and yet mounted axially movable relative to the slide housing. This is achieved in the example shown in that the spring holder 7.3 an integral
- Fork portion forms, which a rib 9.3 of the valve body.
- Stop surfaces 9.6 on the slide housing 9 limit the possible compression of the spring element 7.2.
- the spring element 7.2 is advantageously arranged such that it with its axial ends a shock with the spring holder 7.3 and the boom 9.4 of the
- Pendulum arm 9.1 forms.
- the spring element 7.2 can preload the eccentric shaft 10 mounted on the pendulum arm 9.1 in the direction of the abutment section 6.
- a rotation of the adjusting screw 7.1 triggers an axial movement of the spring holder 7.3, as a result of which the spring element 7.2 is compressed or relaxed.
- An adjustment of the introduced on the pendulum arm 9.1 biasing force is thus made possible by a simple rotation of the adjusting screw 7.1, which by the
- the spring element 7.2 is formed in the illustrated preferred embodiment as a wave spring. This has the advantage that wave springs
- Adjusting screw 7.1 are formed in the example shown as a self-locking thread (eg., As trapezoidal thread) to prevent the axial position of the spring holder 7.3 changed due to the biasing force or to ensure that the set by the user pressure force is maintained.
- a circumferential crown-shaped detent 15 is provided, which cooperates with a corresponding detent portion 16 (eg. A triangular-shaped snap-in lug) of the valve body 9 to an unintentional Vers kind the adjusting 7.1. (in addition to the self-locking thread) to prevent.
- the detent 15, 16 also gives the user a better haptic and acoustic feedback when going through the angular steps, when this adjusts the pressing force by means of the biasing device 7.
- Fig. 5 shows a schematic representation of a balance of forces within the illustrated displacement device 5.
- the eccentric shaft 10 urges the slider 8 in the direction of the flexible hose 2 to effect a displacement. This is held by the fixed abutment portion 6 whereby a restoring force FR arises, which on the eccentric shaft 10 and thus also on the boom 9.1 (on which the eccentric shaft 10 is rotatably mounted). Consequently, a torque is created on the slide housing hinge 9.2, on which the pendulum arm 9.1 is pivotally mounted.
- Arm 9.5 undergoes a biasing force Fv by the spring element 7.2, which is aligned perpendicular to the return force FR and counteracts the torque generated by the restoring force FR.
- Fig. 6 is an alternative embodiment of an inventive
- volumetric pump 1 which in this case not as
- the housing 4 is a
- Insertion recess formed with a substantially arcuate outer edge, which represents the abutment portion 6.
- the displacement device 5 is formed in the embodiment shown in Fig. 6 as a pump rotor 5, which is rotatably mounted in the housing 4 and a number (here three) of pressure rollers or shoes 5.1 has.
- the pump rotor 5 is arranged within the recess so that it forms an arcuate gap in conjunction with the part-circular edge of the same (ie the abutment portion 6), in which the flexible tube 2 is inserted or inserted.
- the hose 2 undergoes a pressure force traveling in the axial direction of the hose (in the circumferential direction of the pump rotor 5) by the pressure rollers 5.1, which compresses the hose 2 to a defined extent in cooperation with the abutment portion 6 and in this way Moves volume in a conveying direction / promotes.
- the pressing force is made adjustable.
- the pump 1 for this purpose has two separate adjusting springs 7, with which the abutment portion 6 and the pump rotor 5 are each biased against each other (towards each other).
- both adjusting springs 7 are arranged in the housing 4 (for example in a through-bore in the same) in such a way that they can be adjusted from the outside, without the door 3 having to be opened or the housing 4 being dismantled.
- the abutment portion 6 is mounted relative to the rest of the housing 4 relatively movable in the example shown, to bias it against the pump rotor 5 to enable.
- the biasing force of the biasing device 7, which applies the biasing force to the pump rotor 5 and thus urges it in the direction of the abutment portion 6, is introduced into the rotor axis 5.2.
- biasing device 7 which biases either the pump rotor 5 or the abutment portion 6 toward the other component 5, 6.
- volumetric pump 1 is therefore characterized by various design measures (such as, for example, the mutually perpendicular
- Displacement device (peristaltic mechanism) from the outside and without disassembly of the housing 4 can be adjusted. For the user, this means that the pressure force could even be adjusted without the tube 2 (disposable) would have to be removed.
