Claims
- 1. A safety hood for hypodermic needles, comprising an elongated body having a U-shaped cross-section formed to surround and enclose a needle and two ends spaced from one another in a direction of elongation, one of said ends being closed; means for preventing undesired withdrawal of a needle from said hood, provided in said body; and a pivot member provided on another of said ends, said pivot member being connected to said body and connectable to the needle and including a springy flip-flop element formed so that said body can be turned in a direction transverse to its direction of elongation between a first position in which said body surrounds and closes the needle and a second position in which said body is turned away from the needle and exposes the needle, said pivot member having a first solid portion and a second portion having lateral arms and a central angular arm which together form a flip-flop spring with said arms resiliently joined to said solid portion.
- 2. A safety hood as defined in claim 1, wherein said body is provided with at least one needle bearing.
- 3. A safety hood as defined in claim 1, wherein said body is provided with a vise-wall having parts provided with oblique cuttings for guiding the needle during its insertion.
- 4. A safety hood as defined in claim 1, wherein said preventing means includes a pair of locking lugs projecting from said body and having oblique guide cuttings.
- 5. A safety hood as defined in claim 4, wherein said lugs are coplanar.
- 6. A safety hood as defined in claim 1; and further comprising an adaptor member having an adaptor body for mounting between a base of a syringe nozzle and a needle base, said adaptor member having a stop shoulder in its interior.
- 7. A safety hood as defined in claim 6, wherein said adaptor member is integral with said needle base.
- 8. A safety hood for hypodermic needles, comprising an elongated body having a U-shaped cross-section formed to surround and enclose a needle and two ends spaced from one another in a direction of elongation, one of said ends being closed; means for preventing undesired withdrawal of a needle from said hood, provided in said body; a pivot member provided on another of said ends, said pivot member being connected to said body and connectable to the needle and including a springy flip-flop element formed so that said body can be turned in a direction transverse to its direction of elongation between a first position in which said body surrounds and closes the needle and a second position in which said body is turned away from the needle and exposes the needle, said body being provided with at least one needle bearing and a vise-wall having parts with oblique cuttings for guiding the needle during its insertion, said preventing means including a pair of locking lugs projecting from said body and having oblique guide cuttings, said lugs having end formations providing a locking closure of the needle and formed as end projections shaped as teeth, said pivot member having a first solid portion and a second portion having lateral arms and a central angular arm which together form a flip-flop spring and are resiliently joined to said solid portion; and an adapter member with an adaptor body for mounting between a base of a syringe nozzle and a needle base and having a stop shoulder in its interior.
- 9. A safety hood for hypodermic needles, comprising an elongated body having a U-shaped cross-section formed to surround and enclose a needle and two ends spaced from one another in a direction of elongation, one of said ends being closed; means for preventing undesired withdrawal of a needle from said hood, provided in said body; and a pivot member provided on another of said ends, said pivot member being connected to said body and connectable to the needle and including a springy flip-flop element formed so that said body can be turned in a direction transverse to its direction of elongation between a first position in which said body surrounds and closes the needle and a second position in which said body is turned away from the needle and exposes the needle, said preventing means including a pair of locking lugs projecting from said body and having end formations which provide a locking closure of the needle and are formed as teeth.
