drug-carrying strip

Description:

The invention relates to a device for dispensing active ingredient or drug-carrying strip with a housing in which a coil chamber for receiving a drug-containing or drug-carrying band is arranged, in which a gear train is mounted with a driven roller for conveying the tape and in which a separating device for separating the Strip is arranged from the belt and a method for dispensing active ingredient-carrying or drug-carrying strip with such a device, wherein between the driven roller and the pressure roller, a drug-containing or drug-carrying band is arranged.

From EP 0 953 362 A2 such a device is known. It requires a battery-powered electric drive that drives two gears in opposite directions. Between the gears, the belt to be conveyed is pressed by means of a pressure spring. The metered amount can be controlled by means of an electrical control device.

The present invention is based on the problem, a

Device and method for donating active ingredient or

drug-carrying strip with largely the same drug dose to

develop.

This problem is solved with the features of the main claim. For this purpose, the gearbox is preceded by a clutch transmission. The clutch transmission has a manually actuable release element. The output roller can be driven in incremental steps by means of the clutch transmission.

When using the device triggers a manual operation of the

Tripping element switching the clutch transmission off. The

Shifting the clutch transmission couples a movement of the

Trigger element with the rotation of a drive wheel, so that the drive wheel rotates by a defined angle of rotation. The drive wheel transmits the

Rotary movement by means of the gear train on the driven pulley. The rotating output roller promotes the belt. The promotion of the band around the of

defined rotational angle of the drive wheel dependent path releases the separator. By means of the separator, a strip is separated from the belt.

The operation of the clutch transmission by means of a push-button, pull handle or rotary switch causes a stepwise rotation of the

Drive wheel. The angle of rotation of the drive wheel is one unit or an integer multiple of this one unit. After turning the

Drive wheel takes this a new stable angular position with respect to its axis of rotation and the trigger element returns to its original position. By means of the downstream gear train, the rotational movement of the drive wheel is transmitted to an output roller which conveys the active substance-containing or active substance-carrying band from a reel chamber in the direction of an output region. After completion of the conveying operation of the band are separated by this means by means of a separating device active ingredient or drug-carrying strips. The separating device is actuated here separately or by means of the triggering elements. After removing the strip from the dispensing area, another strip can be created. A pushing back already promoted strip is blocked by the device. The strip dispenser works purely mechanically. Further details of the invention will become apparent from the dependent claims and the following descriptions schematically illustrated

Another embodiment of a device for dispensing strips with a rotatable trigger element.

Figures 1 - 5 show a first embodiment of a device (10) for dispensing strips. Such devices (10) are used to deliver a precise dose of a drug, e.g. Insulin, to the user or to a patient.

The device (10) comprises a housing (11) in which a

Spool chamber (12), a drive device (71) and a separating device (161) are arranged. The housing (11) has at least approximately the shape of a cylindrical disc with a bottom (13) and a Top (14). The longitudinal direction (15) is defined below as normal to the flat region of the lower side (13) and the upper side (14). At the bottom (13) as a triggering and actuating element (91) a switch button (91) is arranged. Opposite the switch button (91) - ie on its upper side (14) - the housing (11) has a protruding hood (18). The unactuated device (10) is thus at least approximately symmetrical to its central transverse plane. A discharge area (17) arranged on the peripheral surface (16) of the housing (11) is closed in the representation of FIG. 1 by means of a protective flap (68).

In the coil chamber (12) is in the illustrations of Figures 2-4, a drug-containing or drug-carrying band (221) stored rolled up.

For example, this is a self-wound oral drug film having active pharmaceutical agents on its active agent-containing film layer. The strips produced therefrom are e.g. applied to the oral mucosa. It is also conceivable to store the strip (221) on a spool. This coil can be rotatably mounted on a housing-fixed bobbin. The band (221) has a constant cross section over its length. The free end (222) of the band (221) points in the direction of the output area (17). The band (221) is protected in the coil chamber (12) from dust, moisture, UV light, other environmental influences and damage.

The drive device (71) comprises a gear transmission (121) and a clutch transmission (72) upstream of this. The gear train (121) has a driven roller (154) mounted in the housing (11), which is loaded by means of a pressure roller (158). The pressure roller (158) may be spring-loaded in the direction of the driven roller (154). Between the output roller (154) and the rotatably mounted pressure roller (158) is the band (221) in the

Conveying direction (225) guided in the direction of the discharge area (17). The

Output roller (154) for this purpose has a cylindrically shaped rolling surface (156), whose longitudinal length (15) oriented length corresponds to the length of the pressure roller (158). For example, it slightly protrudes on both sides of the belt (221). Optionally, the pressure roller (158) may be made of an elastic material, eg rubber. The The rolling surface (156) of the driven roller (154) can be made of this material.

The driven roller (154) has a second rolling area (157) which is arranged coaxially with the rolling surface (156) and offset in the longitudinal direction (15). This Wälzbereich (157) is formed in the embodiment as a spur gear. Its diameter is for example one third larger than the diameter of the rolling surface (156). The gearing of the second

Rolling area (157) may be e.g. as a degree or helical toothing, as

Schneckenradverzahnung, etc. be executed. The training as a friction wheel is conceivable.

In the gear train (121), the output roller (154) is driven at its rolling area (157) by means of a drive wheel (122). In the embodiment, the output roller (154) and the drive wheel (122) parallel to each other

Axes (123, 155). The diameter of the drive wheel (122) is two and a half times the diameter of the Wälzbereichs (157). At a

Rotation of the drive wheel (122), the output roller (154) rotates by 2.5 revolutions. The drive wheel (122) has a toothing in the exemplary embodiment, which meshes with the toothing of the rolling area (157). This gear stage can also be designed as a friction gear stage, bevel gear stage, as a worm and worm wheel, etc.

In an embodiment as a friction gear, it is conceivable that the drive wheel (122) on the rolling surface (156) rolls. The gear train (121) is then arranged including the counter-pressure roller (158) in a common plane. In such an embodiment, all three

Axes (123, 155, 159) may be arranged along a common straight line. In a design as a friction gear, the output roller (154)

for example, be floating along this straight line, so that the pressing force of the counter-pressure roller (158) both the contact between the drive wheel (122) and the driven roller (154) and the contact pressure between the driven roller (154), the belt (221) and the counter-pressure roller (158). The drive wheel (122) has a central hub (124), a web (125) with openings (126) and a circumferential Wälzbund (127). The

Breakthroughs (126) to reduce the moment of inertia are evenly distributed in the web (125). The drive wheel (122) is mounted, for example, on an upper housing part (51) arranged in the housing pin (52) in the axial and radial directions.

On the outside of the hub (124), a driver (128) is arranged, which is integrally formed, for example, on the hub (124). In the exemplary embodiment, the driver (128) is hook-shaped and protrudes approximately radially out of the hub (124). In its longitudinal bore (129), the hub (124) has e.g. five takers (131). These have a constant over their length

Cross-section and are each limited by a Nutanschlags (132).

In the driving grooves (131) engages a shift pinion (74) of a

Gearbox (121) upstream clutch transmission (72). It is also conceivable to arrange the driving grooves on the switching pinion (74) and to connect the engaging drivers to the driving wheel (122), e.g. to mold. The shift clutch transmission (72) further comprises the shift key (91) and a shift spring (73). The switching button (91), the switching spring (73) and the switching pinion (74) are arranged coaxially with each other. The switching spring (73) and the switching pinion (74) are guided in the longitudinal direction (15) along the upper shell housing pin (52). The stroke of the shift pinion (74) in the longitudinal direction (15) is limited by means of a recess (55) of the upper shell housing pin (52).

The switching pinion (74) is cup-shaped in the embodiment. It has an internal spring retainer (75) and e.g. five outboard

Switching pin (76). The spring receptacle (75) is cylindrical and has a front end a support ring (77). This support ring (77) has a central

Bore (78) which surrounds the upper shell housing pin (52). In the longitudinal direction (15) corresponds to the length of the individual switching pin (76) of the length of the Schaltritzels (74). The cross section of the individual switching pin (76) is constant over its length. All normal to the cross-sectional area oriented boundary surfaces of the individual switching pin (76) are parallel to

Longitudinal direction (15) arranged. The thickness of the Schaltritzels (74) in the region of the switching pin (76) is twice the thickness of the hub (124).

The in the direction of the upper housing part (51) oriented portion of

Switching pin (76) inserted in the corresponding driving grooves (131) of the drive wheel (122). This shaft-hub connection is formed in the exemplary embodiment as a splined connection. But it can also be designed as a positive, axially movable coupling in the design of a polygonal profile, serrated profile, feather key or another rigid connection.

In the direction of the lower housing part (31), the switching pins (76) by means of buttons (79) are limited. Each level of each one of these

Button (79) closes with a normal plane to the longitudinal axis (15) an angle of e.g. 45 degrees. In the exemplary embodiment is the single

Button (79) additionally inclined by an angle of 15 degrees, so that the bordering on the envelope surface of the button (79) further in the direction of the housing lower part (31) than the adjacent to the cylindrical part of the limit of the button (79). However, the switching pinion (74) may also be formed with buttons (79) whose radials are oriented parallel to a normal plane of the longitudinal direction (15).

In the spring receptacle (75) of the Schaltritzels (74), the switching spring (73) is arranged, which is supported in the hub (124) of the drive wheel (122). The spring element (73) forming the switching spring (73) is designed, for example, as a cylindrical helical spring in the form of a compression spring. It has a constant winding cross-section and a constant wire thickness over its length. It is also conceivable to form the spring element (73) with a non-constant winding cross-section and / or non-constant wire thickness in order to

For example, to obtain a progressive or degressive spring characteristic. The use of a conical compression spring (73) is conceivable. In the exemplary embodiment, the switching pinion (74) with the switching button (91) forms a releasable form-locking clutch. The switch button (91) has, for example, ten arranged along a guide cylinder (92)

Switchboard guide webs (93). Each of these switch guide ribs (93) has a switch guide surface (94) which is complementary to a

Button (79) of the Schaltritzels (74) is formed. Each switch button guide surface (94) is limited by means of a free surface (95) oriented in the longitudinal direction (15), which is designed as a radial surface of the guide cylinder (92). The ring-shaped end face (96) of the trigger element (91) has an interrupted sawtooth profile.

The triggering element (91) also has two guide openings (97) lying opposite one another, in which, for example, guide pins (34) fastened in the housing (11) are guided. These prevent rotation of the switch button (91) relative to the housing (11) and a loss of the

Switch buttons (91). In the housing (11), the switch button (91) is guided along a lower housing guide tube (35). The minimum stroke of the switch button (91) in the longitudinal direction (15) corresponds in the embodiment of twice the width of its switch button guide surface (94). This width of the switching-button guide surface (94) is the length of the secant of the envelope surface in the region of the switch-guide ribs (93) measured in plan view in a normal plane to the longitudinal axis (15). Depending on the angle the

Shifter guide surface (94) with a normal plane to

Longitudinal direction (15), the minimum stroke is twice the said width multiplied by the tangent of the angle between the switchboard guide surface (94) and the normal plane.

On the inner wall of the lower housing guide tube (35) are

For example, ten end abutment surfaces (36) formed. in the

Embodiment, these are complementary to the buttons (79) formed. The end abutment surfaces (36) are end faces of

Guide tube ribs (37). In the assembled state, a switch contact guide web (93) is arranged in each case between two guide tube ribs (37). It is also conceivable to make the buttons (79) of the switching pinion (74) wider than described above. For example, they can sweep over a 36 degree segment to cover a switch guide surface (94) and an end abutment surface (36) of the guide tube (35).

On the bottom side, the switch button (91) has an external one

Actuator head (98) with a e.g. convex arched actuating surface. The switch button (91) can additionally be fitted against the housing (11) e.g. be sealed by a flexible sealing element to prevent the ingress of

Prevent contamination. This can be designed, for example, elastically deformable. By means of the sealing element and / or between the housing lower part (31) and the actuating head (98)

arranged return spring (99), e.g. a compression spring, the

Switch button (91) are returned to its original position.

The driver (128) of the drive wheel (22) meshes with a

Ratchet wheel (211). This is rotatably mounted on the upper shell (51) of the housing (11) on a pivot pin. Every time the drive wheel (122) rotates, the detent wheel (211) becomes a sawtooth-shaped one

Lock (212) further rotated. On the side facing the inner wall of the upper shell (51), the detent wheel (211) has, for example, a colored segment-like marking (213). The housing (11) has in his

Upper shell (51) has a viewing window (53) through which the detent wheel (211) is visible. For example, the mark (213) forms a

Residual quantity indicator. If it becomes visible, the band (221) or - if the device is not refillable (10) - the device (10) to be replaced.

In the bobbin case (12), the coil (223) wound band (221) is freely rotatably mounted. The coil (223) may also be on a housing side

Spool pins or be arranged on a in the housing (11) mounted coil carrier. From the spool (223), the belt (221) is guided between the driven roller (154) and the pressure roller (158). The pressure roller (158) presses the belt (221) against the driven roller (154). When turning the output roller (154) shown in Figure 2 counterclockwise, the Belt (221) in the conveying direction (225) in the direction of the discharge area (17) promoted.

The separating device (161) has a camshaft (162), a

Swing frame (171) and a locking slide (201). The

Camshaft (162), for example, fixed to the pivot shaft (165) of the housing (11) pivotally mounted protective flap (68). In the illustration of Figure 2 when opening the protective flap (68) the

Camshaft (162) pivoted clockwise. The pivot angle of the protective flap (68) from the closed to the open position is for example 90 degrees. The camshaft (162) has a

cylinder portion shaped portion (163) and a cam tip portion (164). It is also conceivable to form the camshaft (162) only with a half cam. The half-cam then connects the cylinder-section-shaped region (163) with the cam tip region (164) on only one side. It is also conceivable, the camshaft (162) with two mutually in

Form longitudinal direction (15) offset areas, for example, are rotated against each other.

When the protective cover (68) is closed, the camshaft (162) is in contact with the cylinder-section-shaped region (163) on the locking slide (201) and on the pivoting frame (171) or has a short distance to these two components. The locking slide (201) has a slide portion (202), a compression spring portion (203) and a bending spring portion (204). In the exemplary embodiment, it is displaceably mounted in the lower shell (31) in the radial direction to the center line of the clutch transmission (72). Of the

Slider portion (202) may be wedge-shaped at its free end. The locking slide (201) is shown in the figure 3

Rest position linearly adjustable to a blocking position. Of the

Compression spring region (203) has an actuating rod (205), which with

rhombus-shaped webs (206) is connected. The bending spring region (204) arranged transversely thereto comprises two bending webs (207), which surround, for example, housing-side spring pins (38). The rod-shaped formed slide portion (202) is in an opening (39) of the

Switch button recess (41) of the housing (11) out.

When the protective flap (68) is opened, the camshaft (162) rolls along the locking slide (201) in the direction of the cam tip (164). Of the

Locking slide (201) is moved in the direction of the locking position. Here, both the webs (206) and the bending spring area (204) are elastically deformed. The slide rod (202) is moved into the switch-button recess (41) and engages there behind the actuating head (98) of the

Switch buttons (91). The switch button (91) is thus opened

Protective flap (68) blocked in the unactuated position. If an axial displacement of the slide rod (202) should be blocked, prevent the elastically deformable portions of the locking slide (201) damage to the device (10).

The swing frame (171) is formed in the embodiment U-shaped. It is mounted on the shaft of the driven pulley (154). For storage, it has two frame arms (172) which engage around the output roller (154) at their end faces. At the freely projecting ends of the frame arms (172) each have a return spring (173) is arranged. These trained as bending springs

Return springs (173) support the rear end of the swing frame in the conveying direction (225) on a housing-side support pin (19). The free ends of the frame arms (172) abut, for example, on the camshaft (162) or have a small distance to this. The area of

Camshaft (162), which is coupled to the pivot frame (171) can have a different angular position than the region of the camshaft (162) which couples with the locking slide (201).

The cross bar (174) of the bar connecting the two frame arms (172)

Swing frame (174) includes a knife holder (175) and a

Downholder (179). The knife holder (175) consists for example of a rigid holder with a transverse receiving groove for receiving the

Cutting knife (177). The transversely to the conveying direction (225) aligned

Cutting edge (178) points in the illustrations of Figures 2 and 3 upwards. The hold-down (179) has two spaced-apart, elastically deformable hold-down bending springs (181, 182). These are aligned parallel to the cutting blade (177). In this case, the first hold-down bending spring (181) situated at the rear in the conveying direction (225) has the same distance from the cutting blade (177) as the second hold-down bending spring (182) located at the front in the conveying direction (225). In the illustration of Figures 2 and 3, both hold-down bending springs (181, 182) are spaced from the belt (221).

In the housing (11) a strip-guiding element (42) is arranged. This is between the driven roller (154) and the first hold-down bending spring (181). On the holding-down bending springs (181, 182) facing away from the band (221), a counter-holder (21) is arranged.

When assembling the device (10), for example, in the

Upper shell (51) of the housing (11) the detent wheel (211) on the

The pivot pin is set so that it engages behind the detent wheel (211). On the upper shell housing pin (52), the drive wheel (122)

pushed against the pin stop (43), for example, so that it is freely rotatably mounted. In the hub (124) of the drive wheel (122) is the

Compressed spring (73) inserted. On the compression spring (73) the shift pinion (74) is placed so that the switching pin (76) in the driving grooves (131) of the drive wheel (122) protrude. The support ring (77) then sits captive in the Zapfenausnehmung (55).

In the cup-shaped housing cap (61), the pressure roller (158) is used. Furthermore, the camshaft (162) in the

Housing cap (61) inserted and secured with the through the housing cap (61) and the camshaft (162) pushed through polygonal shaft (165). This Vielkantwelle (165) has two storage areas (166), with which it is mounted in the housing cap (61). Outside the bearing areas (166), the polygonal shaft (165) has, for example, hexagonal pins (167) which project out of the housing cap (61) on both sides after insertion. On the outside of the Housing cap (61), the protective flap (68) is placed, so that the protective flap (68) positively engages the hexagonal pin (167).

In the lower shell (31) of the housing (11), for example, first of the bottom (13) of the switch button (91) is used. On the inside of the lower shell (31) of the locking slide (201) is inserted. The

Output roller (154) and the cutting blade (177) are in the

Swing frame (171) used. This unit is then pushed onto the bearing pin (44) of the housing lower part (31). After the tape (221) is inserted into the bobbin case (12), its free end (222) is pulled at least into the region of the tape guide element (42). It is also conceivable to pull the free end (222) into the area of the cutting blade (177) or into the dispensing area (17).

For closing the housing (11), for example, first the lower shell (31) with the components arranged therein and the upper shell (51) with the components arranged therein are joined together. The joining may be solvable, e.g. by means of a snap connection or insoluble, e.g. done by means of an adhesive bond. Subsequently, the housing cap (61) with the built-in components with the composite of the lower shell (31) and the upper shell (51) is joined. This joint connection can be made detachable or insoluble.

The assembly of the individual subassemblies and the entire device (10) can also be done in a different order. It is also conceivable to assign individual components to other subassemblies. For example, all gear parts in the lower shell (31) may be pre-assembled, so that the upper shell (51) forms a device cover. With such a construction, the device (10) can be easily tested before closing.

In use, the operator takes the one illustrated in FIG

Device (10) in a hand. Here, for example, shows the upper shell (51) upwards. The lower shell (31) lies in the palm of the hand. The protective flap (68) is closed. To operate the operator presses the switch button (91) relative to the housing (11) in the direction of the upper shell (51). The clutch transmission (72) is operated. The switch button (91) moves the shift pinion (74) against the force of the compression spring (73) in the longitudinal direction (15) relative to the housing (11). Figure 6 shows the clutch transmission (72) schematically before the operation. The guide tube ribs (37) are hatched. The switch guide webs (93) are at the top and the switch pins (76) of the shift ratchet (74) are shown below. The buttons (79) of the shift ratchet (74) abut the shift button guide surfaces (94). The end abutment surfaces (36) of the lower housing guide tube (35) are aligned with the right next to the adjacent switch guide surfaces (94). The

Clutch transmission (72) is positively secured.

Upon actuation of the switch button (91), this is displaced along the guide of the lower housing guide tube (35) in the longitudinal direction (15). The first on the guide tube ribs (37) of the lower shell (31) abutting shadows (76) are moved relative to the lower shell (31). FIG. 7 shows the shift clutch transmission with displaced shift pinion (74). The clutch transmission (72) is disengaged. To facilitate the

Understand the switching pins (76) in the longitudinal direction (15) are clearly spaced from the guide tube ribs (37) shown. However, it is also conceivable to limit the stroke of the switching button (91) such that in the loaded position, the individual end abutment surface (36) of the lower housing guide tube (35) is aligned with the switching button guide surface (94) lying to the left ,

On the shift pinion (74) against the actuation direction of

Triggering element (91) acting force of the switching spring (73) has a

Component that works in parallel with the button (79). This component causes a rotation of the switching pinion (74) in the illustration of Figure 7 to the right. The shift pinion (74) slides along the switchboard guide surface (94), relaxing the compression spring (73). The rotating shift pinion (74) takes over the switching pin (76) the

Drive wheel (122) with. In the illustration of Figure 2, the drive wheel (122) rotates clockwise. The drive wheel (122) drives the output roller (154), which rotates counterclockwise. The output roller (154) pulls over the

Friction pressing between the counter-pressure roller (158) and the rolling surface (156) the tape (221) from the bobbin case (12) out and promotes it in the direction of the discharge area (17).

The shift pinion (74) rotates until it rests against the next switchgear web (93), cf. Figure 8. Optionally, the shift pinion (74) in addition to the housing-side end abutment surface (36) strike.

As soon as the operator releases the switch button (91), the switch button return spring (99) causes the switch button (91) to move out relative to the switch button (91)

Housing (11). For example, the switch guide webs (93) are moved back to the starting position shown in Figure 9.

The buttons (79) of the Schaltritzels (74) now slide - loaded by the relaxing compression spring (73) - on the contact surface (36) and the

Switch button guide surface (94) of the next switch guide rail (93) along. The shift pinion (74) continues to rotate the drive wheel (122) which continues to convey the belt (221) by means of the driven pulley (154). These

Rotational movement takes place until the individual switching pin (76) abuts the next direction of rotation in the guide tube rib (37). The

Clutch transmission (72) Is now engaged positively again.

The operator can now lift the protective flap (68). Here is the

Switch button (91) locked by means of the locking slide (201), as above

described. Optionally, the locking slide (201) - at a

Device (10) without switch button return spring - push the switch button (91) back to its original position. With the insertion of the

Locking slide (201), the last described above conveying step can be triggered. The camshaft (162), which is rotated when the protective flap (68) is opened, pivots the pivoting frame (171) out of the rest position shown in FIGS. 2 and 3 into a pivoting end position. From the illustration of Figure 2, the swing frame (171) is pivoted clockwise. The hold-down device (179) pivots against the counter-holder (21) and holds the band (221) firmly by means of the hold-down bending springs (181, 182). When further pressing the

Bandes (221) cuts the cutting blade (177) the band (221). The separated active substance-containing or active ingredient-carrying strip is in

Output area (17) and is held by the blank holder (179). The operator can remove the strip by overcoming the force of the strip

Hold-down (179) or after a slight closing of the

Remove the protective flap (68).

The tape (221) or the strip in the output area can not

be pushed back as an opening of the protective flap (68) the

Downholder (179) and the locking slide (201) operated. The belt (221) and the drive device (71) are blocked. Due to the

Clutch transmission (72) is the conveying of the belt (221) in only one direction possible.

After removing the strip and closing the protective flap (68), after the switching button (91) has been actuated, the strip (221) can be conveyed further in the direction of the dispensing area (17) in order to remove further strips. By means of the remainder quantity display (213), the level of the belt can be monitored. Optionally, in a detachably joined housing (11) - after consumption of the belt (221), a new band (221) can be used.

It is also conceivable to produce a drug-containing or active substance-containing strip of greater length. The length of the strip is then an integer multiple of the length described above. In order to produce such a strip, the trigger element (91) is actuated several times before the protective flap (68) is opened. The protective flap (68) may for example be transparent and have a scale. For this is one Dose unit display connected to the drive device (71). Thus, for example, overdoses can be detected. Each time the trigger element (91) is pressed, the user receives, for example, an acoustic and haptic signal.

FIG. 10 shows a bottom view of a further device (10). This has at least approximately the shape of an equilateral prism. The structure of the drive device (71) corresponds to the structure of the first

Embodiment described device (10). Also in this

Device (10), the switch button (91) on the underside (3) of the housing (11) is arranged.

Figures 11-18 show a further embodiment of a

Device (10) for dispensing strips of a medicated or active substance-carrying band (221). This device (10) has a

Housing (11), in which a drive device (71), a

Spool chamber (12), a separator (161) and a

Dosing device (231) are arranged. The housing (11) has a flat upper side (14) and an underside (13) arranged parallel thereto. The longitudinal direction (15) is defined below as normal to the upper side (14) and to the lower side (13). The device (10) has a handle (22), a

hebeiförmiges triggering element (91) and a frontally arranged, the handle (22) facing away from the output area (17).

The drive device (71) has a clutch transmission (72) and a gearbox (121) connected downstream of the clutch transmission (72). The release lever (91) is mounted, for example, on a housing pin (32). The on the lower shell (31) integrally formed housing pin (32) may be cylindrical or formed, for example, with three stages. In a stepped embodiment of the housing pin (32), the release lever (91) is mounted, for example, on the uppermost stage. The release lever (91) is about a longitudinal axis (15) oriented pivot axis (23) of that shown in Figures 11 to 13

Rest position pivoted into an actuated position. Here, a return spring (99) fixed in the housing (11) and the release lever (91) is e.g. elastically deformed in the design of a torsion spring. The release lever (91) has a handle lever (101) and a knife holder lever (102), between which the pivot bearing (103) is arranged. In the exemplary embodiment of the outwardly projecting handle lever (101) has 1.9 times the length of the within the

Housing (11) lying knife holder lever (102). Of the

Knife holder lever (102) and the handle lever (101) in the illustration of Figure 12 form an angle of 165 degrees.

The release lever (91) has in the handle lever (101) within the housing (11) a radially to the pivot axis (23) arranged latching guide (104). In this latching guide (104) a compression spring (105) is arranged, the one

Locking element (106) centrifugally loaded to the pivot axis (23). The

Locking element (106) is wedge-shaped and is in the direction of

Housing bottom part (31) from the release lever (91) out. The wedge surface (108) is in the operating direction of the trigger element (91) of the

Swivel axis (23) oriented away.

At its free end protruding from the housing (11), the handle lever (101) has a handle (109). The length of the handle (109) in the longitudinal direction (15) corresponds for example to the length of the housing (11) in this direction, reduced by twice the wall thickness. in the

Embodiment, the handle (109) is cup-shaped, wherein the bending line is displaced parallel to the longitudinal direction (15) relative to the handle (109) in the direction of the discharge area (17).

The knife holder lever (102) has a driving pin (111) protruding in the longitudinal direction (15) from the knife holder lever (102). This driving pin (111) is connected to a pivot frame (171) of

Separator (161) coupled. In the illustration of FIG. 12, a metering device (231) is arranged behind the triggering element (91). This comprises a metering lever (232) which is adjustable between the minimum position shown in this figure and a maximum position. The metering lever (232) is mounted on the housing pin (32). In a graduated education of

Housing pin (32) is the metering lever (232), for. stored at the middle level. For example, it can be adjusted by a swivel angle of 63 degrees.

The metering lever (232) has a metering slide (233) protruding from the housing (11), which is e.g. along a housing side

Locking rail (24) gradually adjustable from the minimum position to the maximum position, for example, in six stages. The metering slide (233) can also be infinitely adjustable. For example, it can be a detachable

Clamping device to lock it at the desired position relative to the housing (11). In addition, the metering device (231) may be designed such that the metering slide (233) is connected to the metering lever (232) only during assembly.

At its the metering slide (233) facing away from the end

Metering lever (232) a guide shell (234). The guide shell (234) covers in the exemplary embodiment a sector of 83 degrees, whose

Center is the pivot axis (23). In the unactuated device (10) surrounds the guide shell (234) with a cylinder jacket

formed portion (235) the locking guide (104), so that the

Latching element (106) on the guide shell (234) is supported. In the illustrations of FIGS. 2 and 16, the guide shell (234) on the right side has an insertion bevel (236).

Behind the metering device (231) in the illustration of Figure 12, the drive wheel (122) on the housing pin (32) rotatably arranged. In a stepped configuration of the housing pin (32), the drive wheel (122) is mounted, for example, on the lowest storage stage. The drive wheel (122) is in Embodiment a cup-shaped cylindrical wheel with a

Internal toothing (133) and with an external toothing (134).

The internal toothing (133) is a driving toothing with e.g.

30 ratchet teeth (135). Two ratchet teeth (135) each limit one

Latching tooth gap (136) with mutually parallel latching tooth flanks (137). The groove base (138) is formed concave. In the illustrations of FIGS. 12 and 17, the latching teeth (135) each have an insertion bevel (141) adjacent to the latching tooth head (139) on the right-hand side. The distance between the latching tooth flanks (137), for example, is slightly larger than the width of the latching element (106) of the release lever (91). The diameter of the head circle defined by the locking tooth heads (139) is greater by a few tenths of a millimeter than twice the radius of the outer surface of the guide shell (234). In the exemplary embodiment, the normal plane oriented in the longitudinal direction (15) encloses an angle of two degrees in the middle of a groove base (138) with a radial plane. In the illustration of Figure 12, this angle is oriented to the right. The groove base (138) can also be formed coaxially with the longitudinal axis (15) oriented axis of rotation of the drive wheel (122). The limiting the latching tooth gap (136)

Latching tooth flanks (137) are then formed, for example, parallel to this radial plane.

The external toothing (134) of the drive wheel (122) is a

Involute toothing (134). It can be straight or oblique. By means of this involute toothing (134), the drive wheel (122) meshes with an intermediate gear (151) mounted in the housing (11) and having toothing of the same module. The intermediate gear (151) of the three wheels (122, 151, 154) existing, designed as Wälzgetriebe gear train (121) carries in the embodiment offset from each other two gears (152, 153). The second toothing (153) is coupled to the output roller (154). In the exemplary embodiment, the two toothings (152, 153) have the same pitch circle and, for example, identical modules, so that the envelope contour of the

Zwischenrades (151) is a cylinder jacket surface. It is also conceivable to arrange the entire Wälzgetriebe (121) in a transmission plane. The Gearing (152; 153) of the intermediate gear (151) then meshes both with the drive wheel (122) and with the toothing of the output roller (154). It is also conceivable to design the toothings (152, 153) of the intermediate gear (151) with different pitch circles and / or with different modules.

The output roller (54) and the pressure roller (158) are formed in this embodiment as described in connection with the first embodiment.

The separating device (161) comprises a swiveling frame (171) mounted pivotably in the housing (11), in which a holding-down device (179) and a separating tool (177) are held. The swing frame (171) has a pivot hub (183) which engages in the installed state in the longitudinal direction (15) oriented housing-side pivot pin. A radially directed to the longitudinal direction (15) pivoting web (184) points in the direction of

Output area (17). In the illustrations of FIGS. 12 and 13, the pivot web (184) surrounds the pressure roller (158). The pivot web (184) has a guide slot (185) which receives the driving pin (111) of the release lever (91). The e.g. embossed guide cusp (185) has four sections (186 - 189) which together form a polygon. A first e.g. Wedge-shaped lift section (186) has a constant depth. He closes

For example, with said radial to the pivot hub (183) facing away from the pivot hub (183) angle of 15 degrees, see. the

Figures 12 and 18. In the basic position of the driving pin (111) sits at the apex of this angle. The lifting section (186) is, for example, on its underside, see. Figure 18, open.

At the end remote from the apex, a freewheeling section (187) is connected to the lifting section (186). This, for example, arcuate portion (187) is concentric with the pivot hub (183) and leads in the illustrations of Figures 12 and 18 upwards. But it is also conceivable to form the freewheeling section (187) as a wide, eg straight groove. The depth the freewheeling section (187) corresponds to the depth of the lifting section (186), but it may also be formed deeper.

Adjoining the freewheeling section (187) is a return stroke section (188) which, for example, has the same depth as the lifting section (186) and the

Freewheel section (187). In the illustrations of FIGS. 12 and 18, the pivot web (184) is designed to be open at the top in the region of the return stroke section (188).

The fourth section (189) is an e. wedge-shaped

Guide section (189) which connects the return stroke section (188) with the lifting section (186) at least in the region of the apex. For example, the backdrop reason in the guide section (189) increases from

Return stroke section (188) in the direction of the lifting portion (186). Of the

Guide portion (189) may also be formed narrower than shown. Another embodiment of the guide slot (185) is conceivable.

The swing frame (171) has a return pivot spring (173). This is for example designed as a projecting leaf spring and in the

Swing frame (171) integrated. It is supported on the inner wall of the housing (11). In the illustration of Figure 12 charged the

Return pivot spring (173) the swing frame (171) counterclockwise.

At the output region (17) facing side of the swing frame (171), the separating tool (177) is arranged. The cutting tool (177) is a longitudinally (15) and transversely to the conveying direction (225) oriented cutting blade (177). In the illustrations of FIGS. 12 and 18, it protrudes downwardly out of the swing frame (171).

The cutting blade (177) is surrounded by a hold-down (179) which is spring loaded in the pivot frame (171) is arranged. The hold-down device (179) is a rectangular frame which is arranged in the longitudinal direction (15) and transversely to the conveying direction (225) and which is displaceably mounted in the swivel frame (171). In the representations of Figures 12 and 13, the hold-down (179) in the vertical direction parallel to the cutting blade (177) is displaceable. Here it is loaded by means of a swivel frame (171) arranged leaf spring (192).

In the coil chamber (12) of the housing (11) is also in this

Embodiment, a drug-carrying or drug-containing band (221) arranged. For example, this is designed as the im

Associated with the first embodiment described band (221).

The housing (11) has a housing lower part (31), a housing cover (51) and a housing cap (61) pivotally formed therewith. The

Housing base (31) is trough-shaped. She is wearing her

Inner wall all pivots for the gear train (121) and the housing pin (32) for the clutch transmission (72).

When mounting the device (10), for example, the first

Housing cap (61) inserted into the lower shell (31), so that the two parts relative to each other about a pivot pin (62) are pivotable. The

Housing cap (61) and the lower housing part (31) may also be integrally formed. In the lower shell (31), the drive wheel (122) is inserted, wherein the locking teeth (135) in the illustration of Figure 12 show upward. On the housing pin (32) then the metering device (231)

plugged so that the mold shell (234) in the drive wheel (122) and the metering lever (232) rests against the housing (11). On further housing pin the intermediate gear (151) and the driven roller (154) are mounted and optionally secured against displacement in the longitudinal direction (15). In the housing cap (61), the pressure roller (158) is mounted. This can be in

Direction of the axis of rotation of the driven roller (154) to be spring loaded. Furthermore, the swing frame (171) with the hold-down (179) and the

Cutting knife (177) inserted into the housing cap (61).

For example, after inserting the band (221) in the

Spool chamber (12), the tape (221) into the area of

Output roller (154) out. After insertion, for example, the free jams End (122) of the belt (112) between the driven roller (154) and the

Pressure roller (158).

On the housing pin (32) of the trigger lever (91) is mounted and the return spring (99) on both the housing (11) and the release lever (91) applied. The driving pin (111) of the release lever (91) is located after installation in the lifting section (186) of the sliding guide (185). The handle (109) protrudes to the outside. In this state, for example, the function of the dispenser device (10) can be tested. At the end of the assembly, the housing cover (51) is placed. Another order of assembly is conceivable.

When using the device (10), the operator grips the housing (11) on the handle (22) and places his fingers on the handle (109) of the

Triggering element (91). When triggered, the handle (109) in the

Representation of Figure 12 moves to the right and thereby to the

Housing pin (32) pivoted. The return spring (99) is tensioned. The locking element (106) slides along the guide shell (234). As soon as the latching element (106) has left the right-hand end of the guide shell (234), it engages, positively loaded by the compression spring (105), in a latching tooth gap (136) of the drive wheel (122). The

Clutch transmission (72) is now engaged. Upon further actuation of the trigger element (91) the drive wheel (122) is taken. The drive wheel (122) drives the driven pulley (154) via the intermediate gear (151), which conveys the belt (221) in the conveying direction (225). The conveying takes place until the release lever (91) has an e. G. housing-side stop abuts.

During the movement of the release lever (91), the driving pin (111) is moved from right to left along the lifting section (186) of the sliding guide (185) in the illustration of FIG. The swing frame (171) is raised, whereby the return pivot spring (173) is loaded. As soon as the release lever (91) bears against the housing-side stop, the driving pin (111) lies in the freewheeling section (187). The swing frame (171), accelerated by the return pivot spring (173), in the starting position pivoted back. Here, the hold-down (179) hits the belt (221) and secures the position of the belt (221) against the counter-holder (21). At the

Deformation of the hold-down spring (192) strikes the cutting blade (177) on the belt (221) and cuts through it. The cut-off portion lies in the discharge area (17) and is held by means of the hold-down (179).

The release lever (91) is moved back after releasing the handle (109) by means of the relaxing return spring (99) in the direction of the starting position shown in Figure 12. This slides the

Wedge surface (108) of the locking element (106) along the insertion bevel (236) of the guide shell (234) in the guide shell (234). The clutch transmission (72) is disengaged. The driving pin (111) moves into the return stroke section (188) and out of this into the guide section (189). In the latter section (189), the release lever (91) is e.g. in the direction of the housing cover (51) elastically deformed, so that the driving pin (111) at the apex back into the lifting section (186) engages. The release lever (91) is now back in the starting position. After removal of the already cut strip, the strip (221) can be conveyed to produce further strips.

If a larger dose of medication is needed, for example, a longer active substance-containing or drug-carrying strip can be produced. For this purpose, the metering slide (233) in the illustrations of Figures 11 and 12 along the locking rail (24), for. shifted to the right and locked in the housing (11). The guide shell (234) is pivoted in the illustration of Figure 12 clockwise about the housing pin (32).

Upon actuation of the release lever (91) engages the locking element (106) already after overcoming a smaller sector in the drive wheel (122). Until the release lever (91) reaches the housing stop, the drive wheel (122) is rotated by a greater angle of rotation than in the example described above. The length of the conveyed belt (221) and the strip produced is proportional to this angle of rotation of the drive wheel (122). This can be the maximum dose of the strip can be adjusted so that overdose is prevented.

If a new band (221) is to be inserted into the device (10), the housing cover (51), for example, is removed and the

Return spring (99) removed. After inserting the new coil in the coil chamber (12), for example, the housing cap (61)

be swung to thread the new band (221).

FIG. 19 shows a further variant of such a device (10). The triggering element (91) is designed as a large-surface switching switch (91), which is arranged laterally on the housing (10). Opposite the trigger element (91) of the metering slide (233) is arranged. The internal structure and function of this device (10) correspond to the structure and function of the device (10) described in the embodiment of FIGS. 11-18.

Figures 20-26 show another device (10) for dispensing strips made from a drug-bearing or drug-carrying band (221). The housing (10) consists in this example of a

Lower shell (31), a housing cover (51) and a two-part housing cap (61). At the top (14) a trigger element (91) is arranged and at the bottom (13) a cap (18). The triggering element (91) designed as a rotary knob (91) may e.g. Have recessed grips. Furthermore, the device (10) has a toggle button (241), which is actuated for separating a strip. The longitudinal direction (15) is also in this

Embodiment defined normal to the top (14) and bottom (13).

In the housing (11) are arranged as a drive device (71) a clutch transmission (72) and a gear train (121). The clutch transmission (72) driven by means of the triggering element (91) drives the gearbox (121). The gear train (121) conveys the belt (221) the bobbin chamber (12) in the direction of the discharge area (17). After actuation of the toggle button (241), a strip separated from the strip (221) can be removed. On the housing (11) is still a display (252) visible, indicating, for example, the number of subsidized since the last separation units of the belt (221).

The knob (91) is rotatably mounted in the housing (11). He has e.g. four driving lugs (113) which engage in a hub (124) of a drive wheel (122) and engage behind. The drive wheel (122) in turn is coupled by means of driving pins (142) with a cup-shaped ratchet wheel (81). The ratchet wheel (81) is displaceable relative to the drive wheel (122) in the longitudinal direction (15). For this purpose, the ratchet wheel (81)

Mitnehmeruten (84) into which the driving pins (142) of the drive wheel (122) engage. It has at its the rotary knob (91) facing away from the bottom (83) has a circumferential sawtooth toothing (82) in a corresponding

Counter toothing (45) of the lower shell (31) engages. Between the

Bottom (83) of the ratchet wheel (81) and the drive wheel (122) is a

Switching spring (73) arranged in the form of a compression spring (73), so that the two components are always pressed apart. An axial bearing of the rotary knob (91) in the housing (11) secures the position of the drive wheel (122) in the longitudinal direction (15).

When turning the knob (91) counterclockwise by an in

Longitudinal (15) oriented axis of rotation, the drive wheel (122) and the ratchet wheel (81) are taken. The compression spring (73) presses the

Ratchet wheel (81) against the counter-toothing (45) of the lower shell (31), so that the Ratchet wheel (81) in the longitudinal direction (15) is moved back and forth. Here, the ratchet wheel (81) is moved from a stable position in which it is positively coupled and locked with the lower shell (31) in a labile position. If the knob (91) is released, turn the knob

Ratchet wheel (81), the drive wheel (122) and the knob (91) in the

Starting position back. Only after overcoming the crest of the

Sawtooth gearing (45, 82) switches the clutch transmission (72). The ratchet wheel (81) engages in the next notch of the counter-toothing (45) a positive fit. The clutch transmission (72) is thus gradually advanced.

Optionally, the device can also from the bottom (13) of the

Housing (11) are actuated from. In this case, for example, the cap (8) is designed as a knob and connected by means of a torsionally rigid coupling with the other components of the clutch transmission (72). To actuate the clutch transmission (72) then the cap (18) is rotated clockwise.

The drive wheel (122) has, for example, an external spur gear toothing (134) which is coupled in a gear train (121) to the output roller (154) by means of a intermediate wheel (151). The intermediate gear (151), the driven roller (154) and the toothings may be formed as described in connection with the previous embodiments. The use of a friction gear is conceivable.

The device (10) can also be designed without intermediate wheel (151).

For example, then show the Sägezahnverzahnungen (45, 82) of the

Ratchet wheel (81) and the housing lower part (31) in the other direction. In such an embodiment, rotating the

Rotary knob (91) in a clockwise direction conveying the belt (221) in the

Conveying direction (225).

In the housing cap (61) of the housing (11), a counter-pressure roller (158) is arranged. This is for example designed as the counter-pressure roller (158) described in connection with the previous embodiments.

The separating device (161) has an in a plan view L-shaped pivot frame (171) having a hold-down (179) and a

Separating tool (177) carries. The hold-down (179) and the

Separating tool (177) are for example formed as in

Related to that shown in Figures 11 to 18

Embodiment described. The pivotal frame (171) shown in an isometric bottom view in FIG. 26 has a pivot hub (183) for receiving a housing-side pivot pin (62) and a recess (193) for

Encompassing the counter-pressure roller (158). On the inside has the

Swing frame (171) a guide slot (185). This is, for example, similar to that formed in connection with the guide slot (185) described in FIG. The vertex position is in this illustration at the left end of the guide slot (185). The lift section (186), the freewheel section (187) and the return stroke section (188) are groove-shaped. The guide portion (189) is formed like a ramp. The swing frame (171) is loaded by means of a return pivot spring (173) in the form of a torsion spring in the direction of a cutting position. In the illustration of FIG. 22, the pivoting frame (171) is concealed by a guide element (63) of the housing (11).

In the housing (11) the toggle button (241) is pivotally mounted. It forms the actuating element of the separating device (161). The toggle button (241) is designed like a lever. On one side of the pivot axis (242) has a tilt stop (243) which limits the pivot angle of the toggle button (241) relative to the housing (11).

The toggle button (241) has a handle portion (244), which protrudes on the output side (17) from the housing (11). The operator can move the toggle switch (241) from a rest position to an operating position by pressing the grip area (244) in the direction of the housing (11). In addition, a return spring, the toggle button (241) from the operating position in the

Return home.

At its free end, the toggle button (241) has a driving pin (245) which, in the illustration of FIG. 21, slides into the guide slot (185) of the

Swing frame (171) engages. In the illustrated rest position of the driving pin (245) is at the apex of the guide slot (185). Of the

Swing frame (171) is spaced in this position to the belt (221). at a depression of the toggle button (241) moves the driving pin (245) along the lifting portion (186) of the guide slot (185). The swing frame (171) is raised against the force of the return pivot spring (173). As soon as the driving pin (245) reaches the freewheeling section (187), the separating device (161) is accelerated in the direction of the belt (221) by means of the return pivoting spring (173). After severing a strip, the toggle button (241) is pivoted back into the starting position, for example, by means of a spring. The driving pin (245) migrates along the

Guide section (189) in the direction of the vertex.

The intermediate gear (151) drives a payer (251). The counter (251) has a gear segment formed Zählradsegment (253), the one

Counter drum (254) with the display (252) drives and a

Decoupling device (261). When turning the intermediate wheel (151), the counting drum (254) is further rotated by one drum segment. Here, as a torsion spring (256) formed return spring (256) is stretched. In the exemplary embodiment, the counting drum (254) can be further extended from the starting position by a maximum of five drum segments. Then that blocks

Gear segment (253) further rotation of the intermediate gear (151).

For example, a cylinder jacket section with the tip circle radius of the gear segment (253) circumferentially bounds the gear segment (253) on both sides. The drum segments are for example by a

View window (64) of the housing (11) visible.

The decoupling device (261) is coupled to the toggle button (241). It comprises a fork rod (262) which is pivotally mounted on the toggle button (241). The fork rod (262) has two fork arms (263) whose free ends are each formed as a shaft receptacle (264). In this wave recordings (264) mounted in the housing cap (61) counter (251) is additionally held. The fork arms (263) can be performed, for example, on the housing (11) in a linear guide. The counter (251) may also be coupled to the drive wheel (122) or to the output roller (154). When assembling the device (10), for example, both the components of the clutch transmission (72) and the components of

Wheels gear (121) inserted into the housing lower part (31). Also, the toggle button (241) with the decoupling device (261) and the band (221) are inserted into the housing lower part (31).

In the housing cap (61) of the swing frame (171) and the

Counter (251) used. After mounting the housing cover (51), the knob (91) and the cover cap (18) are mounted and, e.g.

locked.

In order to dispense a strip of active ingredient-bearing tape (221), the operator turns the knob (91) e.g. against the

Clockwise. The clutch transmission (72) continues the drive wheel (122) in individual steps, the individual steps due to the

Ratchet coupling (81, 31) for the operator acoustically and haptically

are perceptible. The drive wheel (122) drives by means of

Gear train (121) to the output roller (154), which promotes the belt (221) in the conveying direction (225). The counter (251) indicates that a portion of the tape (221), e.g. a unit dose, has been promoted. If a strip of greater length to be generated, the knob (91) is rotated again. The counter (251) continues to count. The maximum length of the strip - and thus the maximum drug dose - is limited by the blocking of the gear train (121) by means of the gear segment (253). To disconnect the strip, the toggle button (241) is pressed, bringing the

Separating device (161) is actuated. The separated strip is held by means of the separating device (161) and can now be removed.

At the same time, the decoupling device (261) is actuated, whereby the

Coupling of the gear segment (253) with the intermediate gear (151) is released. The counting drum (254) rotates, loaded by the return spring (256) back to its original position. When you next use the counting of the units starts again from the beginning. FIG. 27 shows a further embodiment of such a device (10). The knob (91) is on a side surface of the

Housing (11) arranged and has recessed grips (112). Of the

Tilting button (241) is arranged on an end face below the dispensing area (17). At a further, for example, adjacent to the two aforementioned surfaces arranged surface sits the viewing window (64) for the counter (251).

Combinations of the aforementioned embodiments are conceivable.
