BACKGROUND A great number of semi-automatic and fully automatic injection devices have been disclosed. Their construction is often very complex so that manufacturing costs are high. If after being used, a device is not intended for reuse but for disposal or recycling, then a device of this kind has to be composed of few parts and be very cheap to manufacture. Most injection devices which operate semi-automatically or fully automatically do not meet this demand. See for example the fully automatic injection devices according to DE 39 14 818-A1, DE 40 13 769-A1, or DE-UM 92 00 192 (all by Adamaszek). These devices require a first spring for the insertion of the needle and a second spring for the injection of the fluid, and furthermore, corresponding control devices that trigger the injection process by means of the second spring only when the insertion of the needle is finished, as a result of which these devices become very complex and expensive.
SUMMARY OF THE INVENTION This object is achieved according to the invention by an injection device comprising a housing and an injection fluid container which is displaceable in relation to this housing, between a distal and a proximal end position. The device also comprises a pushrod movable, in relation to the housing, to expel fluid from the container. A first connecting device, which acts in a position-dependent and/or direction-dependent manner, is provided between the pushrod and the container. The connecting device between the pushrod and the container is thus preferably a controlled connecting device, i.e. the container follows the motion of the pushrod only when it is logical and required for the operation of the device. Preferably, this connecting device is controlled by the position of the container relative to the housing.
In a movement of the pushrod in the distal direction, the first connecting device is advantageously adapted to produce a unidirectional, positive connection between the pushrod and the container and to move the latter along with the pushrod in the distal direction, and it is furthermore so formed to convert a movement of the pushrod in the proximal direction into a corresponding movement of the container in the proximal direction as long as the container is not prevented from moving in the proximal direction in the housing. Therefore, during a distal movement, the pushrod is positively coupled to the container, that is, their movements are �positively synchronized�, but a proximal movement of the pushrod will move the container only until it has reached its proximal end position in the housing, for example, whereafter the proximal movement of the pushrod will occur independently of the container, in order to expel fluid from the container.
BRIEF FIGURE DESCRIPTION Further details and advantageous improvements of the invention are revealed in the exemplary embodiments described below and shown in the drawings. These exemplary embodiments are in no way to be understood as limitations of the invention.
FIGS. 19 to 21 are various representations of the injection device according to the third embodiment in longitudinal section and in various positions; the cocking spring is not shown, and in FIG. 21, the release (clip), which would not be visible per se in this longitudinal section, is shown rotated by 45�,
FIG. 22 shows a section along line XXII�XXII in FIG. 21,
FIG. 23 shows a section along line XXIII�XXIII in FIG. 21, in the section according to FIG. 23, the internal parts of the injection device are not shown,
DETAILED DESCRIPTION FIGS. 1 to 5 show the course of an injection process in a very schematic form.
The terms �proximal� and �distal� are standard medical terminology; they are defined as follows: proximal: toward the patient, that is, to the left in FIGS. 1-5. distal: away from patient, that is, to the right in FIGS. 1-5.
According to FIG. 11A, the distal section 66 of the retainer 54 is connected to an elastic extension 112 that runs diagonally inward in the distal direction at an angle of 10�, for example, and has a hook 114 on its free, distal end, which engages in a tooth space 28 of the pushrod 14. The extension 112 and hook 114 are used, in cooperation with the tooth spaces 28 of the pushrod 14, as a first connecting device that acts between the pushrod 14 and the retainer 54. As shown in FIG. 12, the proximal side 114 a of the hook 114 runs at an angle 116 to the pushrod 14, and the distal, oblique side 114 b of the hook 114 runs at an angle 118 to the pushrod 14. Angle 116 is on the order of 90� and angle 118 is preferably on the order of 15 to 30�. An angle of 23� turned out to be favorable in tests.
According to FIG. 17, in its distal region, the tubular housing part 132 has a relatively wide longitudinal groove 152 on the bottom (with regard to FIG. 17), which has a rectangular window 154, whose shape is shown clearly in FIG. 17, approximately in the center of the housing part 132. The external thread 148′ (FIG. 17) of the housing part 150 protrudes radially outward through this window 154�through the wall of the tubular housing part 132�so that it can engage with the internal thread 146.
As further indicated in FIG. 17�in part with only dot-and-dash lines 156�on its distal end, the tubular housing part 132 has a longitudinal slot 158 extending from the distal end of this housing part almost to its center. The longitudinal slot 158 is disposed diametrically opposite the window 154 and is equal in width to it. The external thread 148 of the housing part 150 protrudes radially outward through the longitudinal slot 158 to engage with the internal thread 146 of the threaded sleeve 144.
Furthermore, the tubular housing part 132 has a viewing window 160, through which an (approximate) dosage indication 162 can be read on the housing part 150, see FIG. 15. The micro-indication of dosage, e.g. from �0� to �19�, is disposed on the threaded sleeve 144 in the form of indicia 164, and an associated indicator arrow 166 is disposed on the tubular housing part 132. The user thus adds the value 162 in the window 160, e.g. �0�, to the value 164 indicated by the arrow 166, in order to obtain the current setting of the injection device 130, which is zero in FIG. 4. If he then rotates the sleeve 144 three graduation marks in the direction of the arrow 168 (FIG. 14), then he has set a dosage of three units; he only has to change this setting if he wants to subsequently inject a different dosage.
In a schematic representation, FIG. 29 shows an advancing procedure of the toothed rod 222 by half a tooth space, which is indicated in the drawing as �� ZT�. This occurs by virtue of the fact that the advancing part 186 first is displaced in the direction of an arrow 228 in the distal direction by half a tooth space, as shown in the lower part of FIG. 29, where in a manner further described below, the toothed rod 188 is held immobile and the teeth of the advancing part 186 are sliding onwards by half a tooth space, and by virtue of the fact that the advancing part 186 then is displaced in the proximal direction in the direction of an arrow 230, whereby the toothed rod 188 then is displaced in the proximal direction by half a tooth space.
The schematic representations of FIGS. 26 to 28 will provide a clearer understanding of the structure of the toothed rod 188. The axis A�A is shown in all three Figures to make a simple orientation possible.
FIG. 27 only shows the two opposite rows of teeth 218 and 220 which cooperate with the advancing part 186 and are offset in relation to each other by half a tooth space (� ZT), which may also be called a phase shift of 180�.
FIG. 28 shows only the two opposite rows of teeth 246 and 248 that are likewise offset in relation to each other by half a tooth space (� ZT), i.e. have a phase shift of 180�.
First, the threaded sleeve 144 is lockingly engaged on the tubular housing part 132 in the manner previously described. Then, the part 234 is pushed into the housing part 132 from its distal end. With its detent projections 236, the part 234 slides over a corresponding inner detent bead 260 of the housing part 132. The detent projections 236 are shaped so that they permit this kind of a movement in the proximal direction, but not in the distal direction, since then, they act as abutments, as shown in FIG. 21. (In FIG. 21, the clip 176 that serves as a trigger is shown rotated by 45�, i.e. it would not actually be visible in this sectional view. FIG. 21 shows the cocked position for the injection of two units, corresponding to a single tooth spacing of the toothed rod 188.)
The detent connection with the detent member 224 is now released by pressing on the trigger 176 whereby�through the action of the spring 262�the toothed rod 188 assumes the position of FIGS. 19 and 20, and then the cartridge 136 is inserted into the tubular housing part 132 from the proximal end until its plunger or plunger 272 rests against the proximal end 188A of the toothed rod 188. Then the retainer 134 is inserted into the housing part 132, likewise from its proximal end. By means of a corresponding force, its internal micro-detent means 240 engages the micro-detent means 238 on the retainer part 234. The force required for this engagement is measured continuously. When this force increases because the plunger 272 of the cartridge 136 comes into contact against the proximal end 188A of the toothed rod 188, the detent connection process ends since at this point, the retainer 134 is disposed in the correct position on the retainer part 234.
