Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nuclear medicine examination, in particular to a two-handed fixing mat structure used for nuclear medicine examination. Background Art
[0002] Nuclear medicine examination equipment mainly includes positron emission tomography (PET) and single photon emission computed tomography (SPECT). There are many examination items. Radioactive drugs are injected into the subject's body, and the detector of the equipment is used to collect the rays emitted from the subject's body to reconstruct the medical image. In order to reduce the toxic and side effects of radioactive drugs, the injection amount is very small, so the nuclear medicine examination time is generally longer, ranging from a few minutes to an hour. During the examination, the subject must remain completely still, otherwise image artifacts will be generated, affecting the diagnosis. New equipment is generally based on this and is installed with electronic computed tomography (CT) equipment. The detector receives the attenuated X-rays after emitting X-rays through the human body to reconstruct the anatomical image. The two are combined into PET / CT and SPECT / CT, and a single scan can simultaneously obtain PET and CT or SPECT and CT fusion images.
[0003] During nuclear medicine examinations, patients are generally required to cross their hands and raise them above their heads. However, some patients cannot raise their hands due to old age, illness, weakness or periarthritis of the shoulder, and can only place their hands above the abdomen or on the sides of the body. In addition, for head examinations and some whole-body examinations, patients are also required to place their hands above the abdomen or on the sides of the body. Since the aperture of the examination equipment is small, generally about 700 mm in diameter, the examination bed is generally narrow. After lying down, patients with a medium or larger body size have basically no extra space on both sides to place their hands. They can only hold the edge of the bed or the clothes on both sides with both hands to fix their hands. However, this posture requires the strength of both hands to be maintained, which is difficult to maintain for a long time and is prone to shaking. At the same time, placing both hands on both sides will increase the lateral thickness of the body and increase image artifacts. If the fingers of both hands are clasped and placed on the upper abdomen, the posture is relatively comfortable, but at this time the hands are basically in a horizontal position, and the finger bones overlap, further increasing image artifacts. Therefore, the ideal examination posture is to stretch both hands as straight as possible and place them above the thighs on both sides. However, due to the curvature of the upper body and the lack of a support point, this posture is also difficult to maintain for a long time, and it is easy to move during the examination, causing image artifacts. In summary, the position and fixation of the patient's hands have always been a difficulty in this type of nuclear medicine examination.
[0004] Currently, the equipment is generally equipped with some straps, which can be laid on the bed first, and then the patient's body and hands can be tied up after the patient lies down. However, the position needs to be adjusted repeatedly during the binding process, which increases the staff's exposure to radiation time. In addition, the patient's comfort is poor, the fixation effect is average, and it is easy to loosen. Utility Model Content

[0031] Example 2
[0032] Reference Figure 1-6 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: two strip cavities 12 are symmetrically distributed and close to the corresponding sides of the cushion 1 on both sides of the cushion 1, and handle grooves 13 are penetrated at the four corners of the cushion 1. A fixing ring 21 is fixedly installed at one end of the magic snare ring 2, and a magic strip 22 that bypasses the fixing ring 21 is connected to the other end. A magic tape 23 bonded to the magic strip 22 is embedded and sewn on the outer ring wall of the magic snare ring 2, so that the magic snare ring 2 can be fixed on the upper arm of different patients. A slide rail 3 is adaptively embedded and installed in the strip cavity 12, and a first slide groove 31 is penetrated on both sides of the slide rail 3 to facilitate the sliding of the first slider 4, and a second slide groove 32 is opened on the two opposite inner groove walls of the first slide groove 31.
[0033] The remaining structures are the same as those of Example 1.
[0034] Example 3
[0035] Reference Figure 1-6, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a second slider 41 is installed on both sides of the first slider 4 and is slidably installed in the second slide groove 32. A rotating cavity 42 is opened at one end of the first slider 4 close to the handle 47, and a threaded cavity connected to the rotating cavity 42 is opened at one end of the first slider 4 away from the handle 47. A rotating ring 43 is installed in the rotating cavity 42 for rotation. A threaded head 45 is installed in the threaded cavity to conflict with one side of the rotating ring 43. The threaded head 45 is squeezed with one side of the corresponding slide rail 3 at the same time. The handle 47 is pressed against the surface, so that the rotation angle of the handle 47 and the relative position with the cushion 1 can be fixed. A rotating rod 44 that extends through the first slider 4 is fixedly installed on the side of the rotating ring 43 away from the threaded head 45.
