Description

[0001] Nouns and pronouns relating to persons in this patent application are not limited to a specific gender. Technical Field

[0002] The utility model relates to a connecting structure of medical equipment. Background Art

[0003] At present, since the CT system and the PET system are two relatively independent components, most PET-CT systems are assembled from the two systems. The following pain points are often encountered during the design process:

[0004] 1. Due to the limited internal space, assembly interference may occur during the splicing and assembly of the two systems, resulting in damage to components.

[0005] 2. The PET-CT system is relatively long and the scanning bore is relatively dark, so most of them need to be equipped with ambient lights to reduce the patient's fear. The ambient light is generally formed by a transparent plastic cylinder, a point light source located outside the cylinder, and a light guide strip surrounding the cylinder. This will cause the scanning bore shell to be heavier, and due to lack of support, it will be greatly deformed, and it will be difficult to align the two systems at the splicing area, and the height of the whole machine often needs to be adjusted.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments.

[0035] Figure 1 FIG. 1 is a schematic structural diagram of a medical device 101 according to an embodiment of the present utility model. Figure 1 As shown, the medical device 101 includes a first part 102 and a second part 104. The first part 102 can be, for example, a PET system or a SPECT system, and the second part 104 can be, for example, a CT system. In this embodiment, the first part is a PET system and the second part 104 is a CT system. The first part 102 and the second part 104 have aligned circular apertures 106 and 108. The light guide assembly 100 is located between the first part 102 and the second part 104, and includes a support housing 110 and a lamp housing 118. The support housing 110 can be fixed to a sheet metal bracket 134 and further fixed to a stationary portion 136 of the second part 104. The second part 104 can include a window bar 121, and the lamp housing 118 is connected to the window bar 121. The medical device 101 can also include a lamp bead (not shown), a lamp barrel controller 140, and a lamp barrel transformer 142. The lamp barrel controller 140 and the lamp barrel transformer 142 are disposed in the second part 104 and are electrically connected to the lamp bead.

[0036] The supporting shell 110 is hard and can be separated from the shells of the first part 102 and the second part 104. The supporting shell 110 can be injection molded, for example. Figure 2FIG. 1 is a schematic structural diagram of a support housing 110 and a lamp tube housing 118 according to an embodiment of the present utility model. Figure 2 As shown, the supporting housing 110 has a plurality of first holes 112, a plurality of first screw holes 114 and a plurality of third screw holes 115 (refer to Figure 3 ), the third screw hole 115 can be fixed to the second part 104 of the medical device 101.

[0037] In addition, due to the narrow space between the PET system and the CT system, the support shell 110 may also have a wiring seat 146 for the cable 144 to pass through, so as to fix the wiring position of the cable 144 so that it fits on the outer surface of the support shell 110, thereby minimizing the installation space required for the cable.

[0038] The lamp tube housing 118 includes a cylindrical surface 120 and a flange portion 122. The cylindrical surface 120 has a large axial length and is made of a transparent plastic material, so it is heavy on the one hand and easy to deform on the other hand. Fixing the lamp tube housing 118 to the hard support housing 110 greatly enhances the strength of the lamp tube housing 118 and controls its deformation within an acceptable range for the splicing installation of the first part 102 and the second part 104. The cylindrical surface 120 can be installed in the circular aperture 108 of the second part 104. The flange portion 122 has a plurality of second holes 124 and a plurality of second screw holes 126.

[0039] During installation, first install a group of positioning pins 116 (for example, 4) in the first hole 112 of the supporting shell 110, and use the guiding function of the positioning pins 116 to make them pass through the second hole 124 of the flange part 122, so as to pre-position the lamp tube shell 118 on the supporting shell 110, and finally use the first screw 132 that is threadedly matched with the second screw hole 126 and the first screw hole 114 to lock and fix the two shells together.

[0040] The lamp housing 118 may include a light guide bar (not shown), which surrounds the outer side of the cylindrical surface 120. As described above, the medical device 101 may include lamp beads. The light guide bar evenly distributes the light emitted by the lamp beads as point light sources on the cylindrical surface 120 of the lamp housing 118, and acts as an atmosphere light. The light guide bar may be bonded to the outer side of the cylindrical surface 120, for example.

[0041] Figure 3 FIG. 1 is a schematic cross-sectional view of a medical device 101 according to an embodiment of the present invention along a vertical plane where the rotation center is located. Figure 3As shown, the third screw hole 115 of the support housing 110 is fixed to a bracket 134 (e.g., a sheet metal part) by a second screw 138, and the bracket 134 is fixed to a stationary portion 136 of the second portion 104. In this way, the support housing 110 together with the lamp tube housing 118 are completely fixed on the second portion 104, and the relative position between the housing and the second portion 104 is very accurate, so that the housing on the first portion 102 can be easily aligned with the housing of the second portion 104 and installed in place.

[0042] In addition, the supporting shell 110 can cover and protect the rotating parts on the CT and the slip ring area with strong electricity, which can prevent impact and scratches during the splicing and installation of the PET system and the CT system, and protect the operators from touching the live parts.

[0043] The cylindrical surface 120 of the lamp tube housing 118 is located in the circular aperture 108 of the second portion 104 , and the cylindrical surface 120 is connected to the window strip 121 of the second portion 104 .

[0044] The light guide assembly of the utility model has low cost and high strength, and enables the two parts of the medical device to be spliced ​​and installed with high precision, safety and reliability in a very small matching space. In addition, all parts are fixed with screws, which is convenient for replacement. The utility model is suitable for PET-CT products currently on the market, and can also be used for all other medical equipment that needs to be spliced ​​with CT products and has a small internal space and a long overall length of the device.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
