医疗成像设备

Abstract

本实用新型公开了一种医疗成像设备，医疗成像设备包括扫描架，扫描架形成有安装腔和扫描腔，安装腔环绕扫描腔设置，扫描架包括：第一壳体、第二壳体和环状的防护件，第一壳体和第二壳体沿扫描腔的轴向间隔设置，第一壳体和第二壳体彼此邻近的一端在邻近扫描腔一侧的表面上分别形成有沿扫描腔径向凹陷的环形插槽，两个环形插槽的彼此相对的一端敞开设置，防护件在扫描腔轴向上的两端分别位于对应环形插槽内，且分别密封配合于对应环形插槽，以使第一壳体、第二壳体和防护件将扫描腔和安装腔隔开，防护件与环形插槽在扫描腔径向上过盈配合。由此，便于简化防护件的安装过程，且能够减少防护件在安装腔内的占用空间。

Claims

1. A medical imaging apparatus comprising a gantry, characterized in that, The scanning holder has a mounting cavity and a scanning cavity, the mounting cavity being disposed around the scanning cavity, and the scanning holder includes: A first housing and a second housing are provided at an axial distance from each other along the scanning cavity. On the surface of the first housing and the second housing adjacent to each other, there are respectively formed annular slots that are radially recessed along the scanning cavity. The opposite ends of the two annular slots are open. An annular protective member is provided, with its two ends located in the corresponding annular slots along the axial direction of the scanning cavity and respectively sealed to the corresponding annular slots, so that the first housing, the second housing, and the protective member separate the scanning cavity from the mounting cavity. The protective member and the annular slot are interference-fitted in the radial direction of the scanning cavity.

2. The medical imaging device of claim 1, wherein, The annular slot has a larger axial dimension than its radial dimension in the mounting cavity.

3. The medical imaging device of claim 1, wherein, Each of the first housing and the second housing includes a main body and a mating portion. The mating portion is disposed at one end of the main body and defines the annular slot. The mating portion includes a first part and a second part. The first part extends radially outward from the main body and forms a groove sidewall of the annular slot. The second part extends axially from the first part toward the other annular slot and forms a groove bottom wall of the annular slot.

4. The medical imaging device according to claim 1, characterized in that, The thickness of the protective component is less than or equal to the depth of the annular slot.

5. The medical imaging device of claim 1, wherein, The protective component is configured to satisfy at least one of the following conditions: Condition A1: The protective component is made of plastic. Condition A2: The protective component is an anti-static component; Condition A3: The thickness of the protective component is greater than or equal to 1.5 mm and less than or equal to 3 mm.

6. The medical imaging device of claim 1, wherein, The protective component is made of polycarbonate.

7. The medical imaging device according to claim 1, characterized in that, Also includes: A seal is disposed on the bottom wall of at least one of the two annular slots, and in the circumferential direction of the annular slot, the seal spans at least across both sides of the lowest position of the protective member in the height direction of the scanning frame.

8. The medical imaging device of claim 7, wherein, The seal is formed in an arc shape. In the circumferential direction of the annular slot, the central angle between the lowest position of the seal in the height direction of the scanning frame and either of the two end faces of the seal is α, where α ≥ 45°.

9. The medical imaging device of any of claims 1-8, wherein, At least one of the first housing and the second housing is detachably fixed at the end corresponding to the protective member.

10. The medical imaging device of any of claims 1-8, wherein, The protective component has the same thickness distribution in the axial direction of the scanning cavity.
