It includes a barrel part which in one end has a syringe needle and in the other end a flange; a plunger part having a plunger displaceable in the barrel part, said plunger performing movements, enabling medicine to be sucked into and respectively injected from the barrel portion, and having a gripping part connected with the plunger by means of a plunger rod. The device has an opening in one end, through which the injection syringe can at least partly be introduced into a cavity, and an inner part which is provided with a holding device for the barrel part which is changeable between a releasing position and a holding position, in which the barrel portion is held against movements in its longitudinal direction relative to the inner part. A displacement device is provided for displacing the plunger part between a fore and a rear displacement position. The inner part is changeable between a rear position with the syringe needle positioned inside the opening and an advanced position with the syringe needle pushed outside the opening for insertion. The injection device includes an outer part, in which an electric motor is positioned and controlled by means of an electronic device. A transmission connects it to the displacement device for accomplishing its displacement movements in a sequence determined by the control device, for loading the injection syringe, as well as injection after insertion.
I claim: 1. An injection device for medicine, comprising: an outer part forming a housing, and an inner part reciprocably supported in said outer part, said inner part having an opening and a cavity in communication with said opening; and an injection syringe having a barrel part having a first end and a second end, a syringe needle at said first end and a flange at said second end, a plunger part in said barrel part and having a plunger displaceably mounted in said barrel part for sucking medicine into said barrel portion and for injecting medicine from said barrel part, said injection syringe extending through said opening at least partly into said cavity, said inner part having a holding device for the barrel part, said holding device having means movable between a releasing position in which said barrel part is reciprocable in said cavity and a holding position, in which said barrel part is held against movement in said inner part, said inner part also having a displacement device operatively connected to said plunger part and movable relative to said holding device in two directions relative to the barrel part, between a fore and a rear displacement position, said displacement device having gripping means movable between a releasing position and a gripping position and operable to release said plunger part in said fore displacement position of said displacement device and to grip the plunger part in other positions of the plunger part, said inner part being movable in said outer part between a rear position in which said syringe needle is positioned inside said opening and a fore position in which the syringe needle is outside said opening for insertion into body tissue, said injection device including a bottle holder positioned at said opening for positioning at least one medicine bottle for loading of said syringe, during which the syringe needle is inserted into a medicine bottle in said bottle holder and a predetermined amount of medicine is sucked into the barrel part, said injection device including an electric motor positioned in said outer part, an electronic control device in said outer part and operatively connected to said motor, and a transmission connecting said electric motor to said displacement device for effecting said displacement movements of said plunger part in a sequence determined by said control device, for loading the injection syringe and for injecting medicine into the body tissue.
BACKGROUND OF THE INVENTION The present invention refers to an injection device for medical purposes, designed for injection by means of a manual hypodermic syringe. It includes a barrel part which at one end has a syringe needle and at the other end a flange, and a plunger part having a plunger displaceable in the barrel part. The plunger is capable of performing movements, enabling medicine to be sucked into and respectively injected from the barrel part and has gripping means connected with the plunger by means of a plunger rod. The injection device has an opening, through which the injection syringe can at least partly be introduced into a cavity, and an inner part which is provided with a holding device for the barrel part.
BRIEF SUMMARY OF THE INVENTION The object is achieved by means of an injection device according to the present invention, which is characterized in that it comprises a holding device which is changeable between a releasing position and a holding position, in which the barrel part is held against movements in its longitudinal direction relative to the inner part; and in that it also comprises a displacement device for displacing the plunger part in two directions relative to the barrel part between a fore and a rear displacement position, the arrangement being such that the fore displacement position is a releasing position for the plunger part. In the remaining displacement positions it is in a position to bring the plunger part to both displacement positions. The inner part is changeable between a rear position, with the syringe needle positioned inside said opening, and an advanced position, with the syringe needle pushed outside said opening in order to insert the needle into body tissue. The injection device includes an outer part, in which an electric motor is positioned and controlled by means of an electronic control device. The electric motor is by means of a transmission mechanism connected to the displacement device, for accomplishing its displacement movements in a sequence determined by means of the control device for loading the injection syringe, as well as for insertion and injection.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT In FIGS. 1 and 2 the principal construction of the injection device 1 is shown. In its upper part 2 it comprises an opening 3, through which a hypodermic syringe 4 of a disposable type can be introduced, into a cavity 5 in the injection device. The disposable syringe is of a standard type and mainly consists of a barrel part 6 which forms a cylindrical part and in its upper part has a syringe needle 7 and in its rear part is provided with a flange portion 8 in the form of two laterally directed flanges. The disposable syringe 4 furthermore has a plunger part 9 consisting of a plunger 10, a plunger rod 11, and a gripping plate 12, situated at the outer end of the plunger part. The gripping plate 12 is connected to the plunger 10 which is movable inside the syringe 4 in order to aspirate or respectively push medical material through the syringe needle 7. The syringe needle is protected by a detachable top cover 13 attached to the barrel part 6. The injection device 1 is built up of three main parts which are movable relative to each other, viz. an outer part 14, which forms a housing for the injection device, a middle part 15 movable relative to the housing and a movable inner part 16, movable relative to the middle part 15, by e.g. 1/2 to 1 cm.
