Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a bracket of a SPECT examination bed. Background Art

[0002] SPECT is a single photon emission computed tomography scanner that uses radionuclides and their markers for clinical diagnosis and treatment of diseases. The basic principle of SPECT imaging: Radionuclides are labeled with drugs to form imaging agents. After being introduced into the human body through some methods, they are detected and recorded. The uptake of imaging agents by target organs or target tissues in the human body will also emit rays, which are displayed in the form of images. Its imaging method is very flexible and can perform planar imaging, tomographic imaging, static imaging, dynamic imaging, local imaging and whole-body imaging. Patients need to lie on the scanning bed during the examination. Examination of some parts requires the bed to be extended to a length of more than 1200mm. Due to the influence of the patient's weight, the examination bed board will sag and deform.

[0003] Application number: CN201921364246.1 A detection bed bracket for a SPECT system. First, the lifting column needs to be adjusted to the same height as the detection bed board, and then the bed board is moved. Because rollers are provided on the top of the bracket, the bed board can be moved on the top of the bracket and stop at the appropriate position to achieve the purpose of supporting the detection bed.

[0004] However, the supporting side plates and supporting components at the top of the supporting device of the existing equipment cannot be adjusted in length and cannot cope with various situations. Therefore, a testing bed bracket with adjustable support plate length is designed. Utility Model Content

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Embodiment: A bracket for a SPECT examination bed, comprising:

[0040] A base 11, a lifting column 12 is provided on the top of the base 11;

[0041] A detection bed 13 is arranged above the lifting column 12;

[0042] An adjusting device 2 is provided on the top of the lifting column 12, and the adjusting device 2 includes:

[0043] A support plate 21 is arranged on the top of the lifting column 12;

[0044] A slide groove 22 is symmetrically arranged on the top of the support plate 21;

[0045] The second slide grooves 23 are symmetrically arranged on the inner side wall of the first slide groove 22;

[0046] A slide plate 24 is slidably disposed inside the slide groove 1 22;

[0047] A slider 25 is slidably disposed inside the second slide groove 23 and connected to one side of the slide plate 24;

[0048] A rotating rod 26 passes through an outer side wall of the support plate 21 and is rotatably connected to the support plate 21;

[0049] A bevel gear 27, welded to one end of the rotating rod 26;

[0050] The threaded rod 28 symmetrically penetrates the inner side walls of the support plate 21 and the slide plate 24, is rotatably connected to the support plate 21, and is threadedly connected to the slide block 25;

[0051] Bevel gears 29 are welded to one end of the threaded rod 28 and mesh with bevel gear 1 27 .

[0052] Specifically, a handle 31 is provided at the other end of the rotating rod 26, so that the rotating rod 26 can be rotated better and used more conveniently.

[0053] Specifically, an anti-slip cover is provided on the outer side wall of the handle 31 , which can effectively prevent the hand from slipping and make the palm fit the handle 31 more closely.

[0054] Specifically, a ball bearing 32 is disposed on the top of each of the support plate 21 and the slide plate 24 , so as to reduce friction when the detection bed 13 contacts the support plate 21 and the slide plate 24 .

[0055] Specifically, the bottom inner wall of the second slide groove 23 is provided with a second ball bearing 33 , so that the sliding block 25 can slide more smoothly in the second slide groove 23 .

[0056] Specifically, the tops of the support plate 21 and the slide plate 24 are flush, so that both the support plate 21 and the slide plate 24 can contact the testing bed 13, and the supporting force is better.

[0057] Working principle: When the existing device is in use, the height of the lifting column is adjusted so that the supporting side plate contacts the detection bed, and the detection bed is pulled so that the detection bed is completely on the top of the bracket to achieve the purpose of support, but the length of the supporting side plate cannot be adjusted. When the present device is in use, the lifting column 12 is first adjusted to the same height as the detection bed 13, and then the handle 31 is turned to rotate the rotating rod 26, and the bevel gear 1 27 engages with the bevel gear 29 to drive the threaded rod 28 to rotate. At this time, the two threaded rods 28 will rotate in the opposite direction due to the bevel gear 29 in the inner core of the bevel gear 1 27. Because the threaded rod 28 is threadedly connected to the slide plate 24, the slider 25 slides in the slide groove 23, which limits the movement trajectory of the slide plate 24. Therefore, when the threaded rod 28 rotates, because the threads on the threaded rod 28 have the same direction, the two threaded rods 28 rotate in the opposite direction, so when rotating, the slide plate 24 will be pushed to move to both sides, and the area of ​​the support plate 21 and the slide plate 24 is adjusted. When it is appropriate, stop, push the detection bed 13 to the top of the support plate 21, and the detection bed 13 can be supported.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
