Description

Technical Field

[0001] The utility model relates to the technical field of angiography equipment, in particular to an anti-collision structure of a flat-panel detector. Background Art

[0002] The flat-panel detector is the main component required for angiography imaging. When the patient needs angiography, the flat-panel detector assembly needs to move frequently. During the movement, it is inevitable that it will touch the patient or the bed. The installation structure of the flat-panel detector assembly generally has a certain anti-collision function. During angiography, when the detector assembly moves to the required position, it touches the patient or the bed board and the anti-collision function is activated, which is a protective function for the flat-panel assembly and the patient.

[0003] The existing anti-collision structure mainly provides a feedback signal when the bottom of the flat-panel detector touches the patient or the bed board. After receiving the signal, the flat-panel detector power control system will immediately move the touching object away. However, there is still the possibility of collision during the translation process, and the flat-panel detector also needs to be protected. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 4As shown, in the embodiment of the utility model, a collision prevention structure of a flat panel detector 2 is proposed, which is a part of the entire angiography machine. The related circuit control and the like can adopt the existing technology. The present embodiment is to propose a structural improvement to realize the feedback of pressure signals at multiple positions, and does not involve the circuit control part. Specifically, it includes a housing 1 and a flat panel detector 2 installed in the housing 1. The housing 1 includes a bottom shell 3. The bottom shell 3 includes a side surface 31, an angled surface 32 and a bottom surface 33. The side surface 31, the angled surface 32 and the bottom surface 33 are all attached with a thin film pressure sensor 4 and a plate 5 covering the thin film pressure sensor 4. After the thin film pressure sensor 4 is arranged on the side surface 31 and the angled surface 32, the collision of the side surface 31 and the angled surface 32 can be detected during the translation process. When the collision occurs, the pressure signal is fed back to the host to stop the movement, thereby realizing collision prevention. At the same time, the bottom surface 33 is also provided with a thin film pressure sensor 4, which is to feedback the pressure signal when it contacts the patient or the bed board and stop the movement to realize collision prevention. Therefore, anti-collision is achieved on the four sides of the flat-panel detector 2 , the angled surface 32 , and the bottom surface 33 , further improving the all-round protection of the flat-panel detector 2 .

[0026] The thin film pressure sensor 4 may adopt the existing technology, and this embodiment is about the position arrangement and combined application of the thin film pressure sensor 4.

[0027] After a collision occurs, the initial state needs to be reset so that a quick response can be made after the next collision occurs. Therefore, a first reset mechanism 6 for pushing the plate 5 on the side surface 31 and the angled surface 32 to reset is installed in the shell 1, and a second reset mechanism 7 for pushing the plate 5 on the bottom surface 33 to reset is installed in the shell 1; the first reset mechanism 6 and the second reset mechanism 7 are used to realize the reset of the corresponding positions after the collision.

[0028] At the same time, the first reset mechanism 6 and the second reset structure need to be stably installed in the housing 1. Specifically, a support frame 8 is provided in the housing 1, and the flat-panel detector 2 is installed in the support frame 8, wherein the support frame 8 includes a top plate 81 and a bottom plate 82, and a connecting column 83 is provided between the top plate 81 and the bottom plate 82.
