AI Technical Summary

Technical Problem

In current technologies, the extraction of radiopharmaceuticals mainly relies on manual operation, which presents problems such as inconvenience and radiation hazards.

Method used

A needle-piercing mechanism was designed, including a sliding shaft, an operating handle, a needle holder base plate, and an elastic element. The needle-piercing action is achieved through mechanization. Combined with a needle-piercing limiting unit and a buffer mechanism, the needle-piercing position is ensured to be accurate and the bending of the needle and damage to the medicine bottle are avoided.

Benefits of technology

This technology enables mechanized extraction of radiopharmaceuticals, reduces radiation hazards for operators, ensures complete extraction of the drug solution, minimizes residues, and improves operational safety.

Abstract

The utility model discloses an acupuncture mechanism and radiopharmaceutical subpackaging equipment comprising the same. The needling mechanism comprises a sliding shaft, an operating handle sliding up and down along the sliding shaft and a needle frame base plate, the sliding shaft is further sleeved with an elastic piece, the upper end of the elastic piece is connected with the operating handle, the lower end of the elastic piece is connected with the needle frame base plate, and a first buckle used for fixing an extraction needle is arranged on the needle frame base plate. The extraction needle moves up and down along with the needle frame base plate under the action of the operating handle, so that a soft bottle plug of a medicine bottle can be punctured. The operation handle and the needle frame base plate are arranged on the sliding shaft, the elastic piece is arranged between the operation handle and the needle frame base plate, buffering can be ingeniously provided for the extraction needle to pierce a soft bottle plug of a medicine bottle, buffering can also be provided when the extraction needle makes contact with the bottom of the medicine bottle, and bending of the extraction needle and damage to the bottom of the medicine bottle are avoided; the liquid medicine in the medicine bottle can be completely extracted to the maximum extent, the extraction requirement is met, radiation residues are reduced, and harm to operators is reduced.
