Abstract
Abstract A method and an apparatus for treating a part of the body of a patient with radioactive material, in which at least one hollow needle is introduced into the part of the body concerned, said needle being capable of subsequently receiving a tube containing selectively positioned radioactive material, previously arranged therein. Use is made of a cart comprising at least one tube containing selectively positioned radioactive material, an intermediate container for shielding the tube or tubes, and means for transporting the said tube with radioactive material into and out of the shielding means. According to the present invention, each implant needle is connectco to the cart by means of a patient transfer tube with a patient connector and a machine connector connected with plurality of external tubes, from which cart tubes are selectively inserted into the needle or needles already introduced by means of one or more transport threads movable in the patient transfer tubes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
140 words
A method of treating a part of the body of a patient with radioactive material, in which at least one hollow needle is introduced into the part of the body concerned, said needle being capable of subsequently receiving a tube containing selectively positioned radioactive material previously arranged therein and in which use is made of a cart comprising at least one tube containing selectively positioned radioactive material, an intermediate container for shielding the tube or tubes and means for transporting the said tube containing radioactive material into and out of the shielding means, characterized in that each implant needle is connected to the cart by means of a patient transfer tube with a patient connector and a machine connector connected with a plurality of external tubes, from which cart tubes are selectively inserted into the needle or needles already introduced.
Claim 2
Independent Claim
140 words
A method of treating a part of the body of a patient with radioactive material, in which at least one hollow needle is introduced into the part of the body concerned, said needle being capable of subsequently receiving a tube containing selectively positioned radioactive material previously arranged therein and in which use is made of a cart comprising at least one tube containing selectively positioned radioactive material, an intermediate container for shielding the tube or tubes and means for transporting the said tube containing radioactive material into and out of the shielding means, characterized in that each implant needle is connected to the cart by means of a patient transfer tube with a patient connector and a machine connector connected with a plurality of external tubes, from which cart tubes are selectively inserted into the needle or needles already introduced.
Claim 3
Dependent Claim
56 words
A method according to claim 1, characterized in that the positioning of tubes in needles takes place by means of a transport thread movable in the patient transfer tubes and the final position is detected pneumatically by shutting off an air passage bounded by a shoulder, by means of a control head attached to each tube.
Claim 4
Dependent Claim
33 words
A method according to claim 1 or 2, characterized in that the machine connector is connected to a container connector of a storage container from which tubes are selectively pushed into the cart.
Claim 5
Dependent Claim
42 words
A cart for use in the performance of the method according to claims 1, 2 or 3, comprising an intermediate container having a plurality of bent passages, characterized in that a drive mechanism and a control mechanism are arranged behind each passage.
Claim 6
Dependent Claim
46 words
A cart according to claim 4, characterized in that the drive mechanism comprises a drivable disc having a spiral groove accommodating a transport thread whose front end is adapted for coaction with a member, such as a tube, containing selectively positioned radioactive material previously arranged therein.
Claim 7
Dependent Claim
35 words
A cart according to claim 5, characterized in that the free end of the transport thread is fitted with a gripper adapted for detachably receiving therein a head connected to one end of the tube.
Claim 8
Dependent Claim
58 words
A cart according to claim 5 or 6, characterized in that the disc i.3 received in a housing, one sidewall of which is fitted with a radial slot receiving a support fitted with a transport thread guide channel, said support being adapted to be guided through the channel by means of a rotary arm mounted on the housing.
Claim 9
Dependent Claim
31 words
A cart according to claim 7, characterized in that the support is fittad at its bottom with a tongue or lip adapted for coaction with the spiral groove in the disc.
Claim 10
Dependent Claim
27 words
A cart according to claim 7 or 8, characterized in that the arm is fitted at its end facing the disc with a transport thread guide channel.
Claim 11
Dependent Claim
35 words
A cart according to claim 7, 8 or 9, characterized in that the disc is fitted at its outer circumference with worm wheel teeth adapted for coaction with a drivable worm arranged within the housing.
Claim 12
Dependent Claim
11 words
A drive mechanism as described in any one of claims 5-10.
Claim 13
Dependent Claim
103 words
A cart for use in the performance of the method according to claim 1 or 3, comprising an intermediate container having a plurality of bent tubes, characterized in that the tubes 63 are continuous and a transport thread 60 can be moved therethrough, one end of said thread having a pusher 61 and the other end a pulling member or gripper 62 adapted for detachably receiving therein a head 50 connected to one end of the tube 55 with sources 56, while a control head 57 attached to each tube is adapted for coaction with a shoulder 46 of the implant needle 16.
Claim 14
Dependent Claim
38 words
A cart according to claim 12, characterized in that the length of the transport thread 60 substantially corresponds with the length of the patient transfer tubes 14, there being provided a cover mountable on the patient connector 11.
Claim 15
Dependent Claim
59 words
A cart according to claim 12 or 13, characterized in that the free end of each tube 63 has a restriction 64 through which the head 50 but not the shoulder 52 of the flexible rod 53 can be moved, while the rod 51 connected to the said projecting head is adapted for coaction with a blocking bracket 65.
