Abstract
An apparatus for remotely administering radioactive material by a syringe into a patient where the syringe is encapsulated in a lead housing. A lever mechanism is operatively attached to a plunger located within the housing via a rod. The lever mechanism activates the plunger against the plunger head of the syringe during the administration of the radioactive material. A specially designed carrier transports the apparatus from the radioactive source to the patient.
Claims18
An apparatus for remote injection of radioactive solution into a patient, said apparatus adapted to hold a syringe having a needle, syringe plunger and a barrel for containing a quantity of the radioactive solution wherein said radioactive solution emits radioactive rays therefrom, said apparatus comprising:
- a cylindrical shield constructed of radiation attenuating material for enclosing the syringe;
- a housing comprising a first portion and second portion hingedly attached thereto and opening to an inner bore disposed in said housing for encapsulating the syringe shield, said housing having a needle aperture at one end of said housing adapted for insertion of the needle into the syringe and projecting therefrom;
- said housing comprising a reciprocating plunger within the inner bore of the housing;
- an actuating means for selectively moving the plunger in axial movement against the syringe plunger to cause penetration by the needle;
- and
- connecting means for securing the actuating means in axial alignment to the plunger disposed in the housing.
An apparatus for remote injection of radioactive solution into a patient, said apparatus adapted to hold a syringe having a needle, syringe plunger and a barrel for containing a quantity of the radioactive solution, wherein said radioactive solution emits radioactive rays therefrom, said apparatus comprising:
- a shielding means for enclosing said syringe, said shielding means constructed of radiation attenuating material;
- a means for encapsulating the syringe and shielding means, wherein the encapsulating means virtually eliminates radioactive rays from escaping;
- a means for transporting the syringe and encapsulating means to a patient;
- a means for inserting the needle to the syringe through the encapsulating means;
- a means for positioning the needle to a predetermined point of penetration;
- a means for remotely actuating the syringe to cause penetration by the needle and inject the quantity of radioactive solution to the point of penetration.
A method of remotely injecting radioactive solution into a patient wherein said radioactive solution emits radioactive rays therefrom, comprising the steps of:
- shielding syringe in a radiation attenuating material, said syringe having a barrel for containing a quantity of radioactive solution therein;
- encapsulating the syringe, wherein the encapsulating means virtually eliminates radioactive rays from escaping;
- transporting the syringe and encapsulating means to a patient;
- inserting a needle to the syringe through the encapsulating means;
- positioning the needle to a predetermined point of penetration;
- and
- remotely actuating the syringe to cause penetration by the needle for injecting the quantity of radioactive solution to the point of penetration .
