Loader-mixer device for endermic injectors

Claim 2

Loader-mixer device for endermic injectors which is suitable to cooperate with a portable endermic injector momentarily in loading, by means of aspiration through an injection-aspiration nozzle included in an injection head of the portable endermic injector, the product to be injected, the loader-mixer device comprising: at least one seating to lodge and position a respective phial together with two needles, a socket to position the injection head, and a selector assembly to connect one of the two needles to the injection head, in which the selector assembly comprises at least one delivery nozzle positioned eccentrically in said socket for cooperating with at least one angular limit position (A-B) of an injection head to be inserted in said socket, namely an injection head of a kind having an injection-aspiration nozzle which is not aligned with a central longitudinal axis of angular rotation of the endermic injector.

Claim 3

Device as claimed in claim 1, in which the two needles comprise an aeration needle, and a delivery needle.

Claim 4

Device as claimed in claim 2, including a filter interposed between the outside environment and the aeration needle.

Claim 5

Device as claimed in claim 1, wherein said at least one seating includes a plurality of seatings to lodge and position respective phials, in which the selector assembly has a specific loading position for each phial.

Claim 6

Device as claimed in claim 1, in which the selector assembly has a position in which it does not provide communication or loading.

Claim 7

Apparatus for loading an endermic injector, such apparatus comprising, in combination: an endermic injector of the kind having an injection head and an axis of angular rotation including an injection-aspiration nozzle; a loader-mixer device for said endermic injector, said loader-mixer device including: (a) at least one seating to lodge and position a respective phial, and two needles projecting into said at least one seating to communicate with a phial therein, (b) a socket to receive and position the injection head, said socket and injection head having cooperating means permitting angular rotation of said injection head between angular limit positions (A-B) in said socket, the injection-aspiration nozzle being eccentric in relation to an axis of the socket and to said axis of angular rotation of said injection head of the endermic injector, and (c) a selector assembly to connect one of the two needles to the injection head, in which the selector assembly comprises at least one delivery nozzle cooperating with at least one angular limit position (A-B) of the injection head, in which position said at least one delivery nozzle is not aligned with said axis of angular rotation of the endermic injector but is aligned with said injector-aspiration nozzle of said endermic injector.

Claim 8

Apparatus for loading an endermic injector, such apparatus comprising, in combination: an endermic injector of the kind having an injection head and an axis of angular rotation including an injection-aspiration nozzle; a loader-mixer device for said endermic injector, said loader-mixer device including: (a) at least one seating to lodge and position a respective phial, and two needles projecting into said at least one seating to communicate with a phial therein, (b) a socket to receive and position the injection head, said socket and injection head having cooperating means permitting angular rotation of said injection head between angular limit positions (A-B) in said socket, the injection-aspiration nozzle being eccentric in relation to an axis of the socket and to said axis of angular rotation of said injection head of the endermic injector, and (c) a selector assembly to connect one of the two needles to the injection head, in which the selector assembly comprises at least one delivery nozzle cooperating with at least one angular limit position (A-B) of the injection head, in which position said at least one delivery nozzle is not aligned with said axis of angular rotation of the endermic injector but is aligned with said injector-aspiration nozzle of said endermic injector.

Claim 9

Loader-mixer device for endermic injectors which is suitable to cooperate with a portable endermic injector momentarily in loading, by means of aspiration through an injection-aspiration nozzle included in an injection head of the portable endermic injector, the product to be injected, the loader-mixer device comprising: at least one seating to lodge and position a respective phial together with two needles, a socket to position the injection head, and a selector assembly to connect one of the two needles to the injection head, in which the selector assembly comprises at least one delivery nozzle positioned eccentrically in said socket for cooperating with at least one angular limit position (A-B) of an injection head to be inserted in said socket, namely an injection head of a kind having an injection-aspiration nozzle which is not aligned with a central longitudinal axis of angular rotation of the endermic injector, said selector member comprising a disklike member seated eccentrically in said socket and having a pair of said delivery nozzles therein connected to respective ones of said needles, and means on said socket for allowing limited rotational movement of the injection head in said socket.

Claim 10

Loader-mixer device for endermic injectors which is suitable to cooperate with a portable endermic injector momentarily in loading, by means of aspiration through an injection-aspiration nozzle included in an injection head of the portable endermic injector, the product to be injected, the loader-mixer device comprising: at least one seating to lodge and position a respective phial together with two needles, a socket to position the injection head, and a selector assembly to connect one of the two needles to the injection head, in which the selector assembly comprises at least one delivery nozzle positioned eccentrically in said socket for cooperating with at least one angular limit position (A-B) of an injection head to be inserted in said socket, namely an injection head of a kind having an injection-aspiration nozzle which is not aligned with a central longitudinal axis of angular rotation of the endermic injector, said selector member comprising a disklike member seated eccentrically in said socket and having a pair of said delivery nozzles therein connected to respective ones of said needles, and means on said socket for allowing limited rotational movement of the injection head in said socket.
