Abstract
Abstract A device for supporting a patient, having a carrying member and a horizontally extending lying support for the patient, with a motor for varying the distance between the support and a medicinal unit. The invention is particularly characterized by the provision of a spring scale between the patient support and its carrying member, having a switching member which can be shifted corresponding to the weight of the patient. Switching means are connected with the switching member for interrupting the current circuit of the motor, the distance between the switching means and the switching member being adjustable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A device for supporting a patient for use with a medical apparatus, said device comprising a carrying member, a substantially horizontally extending support for the patient, a motor for varying the distance between said support and said medical unit, a supply circuit for said motor, and a spring scale between said support and said carrying member, said spring scale having a switching member shiftable depending upon the weight of a patient, said switching member having switching means for interrupting said supply circuit for said motor and means adjusting the distance of said switching means from said switching member.
Claim 2
Independent Claim
98 words
A device for supporting a patient for use with a medical apparatus, said device comprising a carrying member, a substantially horizontally extending support for the patient, a motor for varying the distance between said support and said medical unit, a supply circuit for said motor, and a spring scale between said support and said carrying member, said spring scale having a switching member shiftable depending upon the weight of a patient, said switching member having switching means for interrupting said supply circuit for said motor and means adjusting the distance of said switching means from said switching member.
Claim 3
Dependent Claim
23 words
A device in accordance with claim 1, comprising parallelogram rods supporting said support upon said carrying member, and spring means engaging said rods.
Claim 4
Dependent Claim
18 words
A device in accordance with claim 1, wherein said motor serves for the movement of said medical unit.
Claim 5
Dependent Claim
15 words
A device in accordance with claim 1, wherein said medical unit is a gamma camera.
Claim 6
Dependent Claim
21 words
A device in accordance with claim 1, wherein said motor serves for the movement of said support in a vertical direction.
Claim 7
Dependent Claim
72 words
A device in accordance with claim 1, comprising a guide fixed upon an upper portion of said carrying member, said switching means being frictionally connected with said guide, and a manually operable actuating member, said switching means interrupting said supply circuit in a basic position and being pressable by said actuating member against said switching member for being switched out of said basic position, thereby freeing the upward movement of said support.
Claim 8
Dependent Claim
50 words
A device in accordance with claim 6, wherein said switching member is a switch lever, and wherein said switching means consist of a switch and another lever carrying said switch and having a swinging axle, said device comprising a friction coupling located between said other lever and said swinging axle.
Claim 9
Dependent Claim
33 words
A device in accordance with claim 6, wherein said spring characteristic is such that switching member always moves by the same distance for a predetermined force added to any weight of a patient.
