Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is further described in detail by referring to the following embodiments.

Fig. 1 is a schematic view of a fixture 100 according to an embodiment of the present invention. Fig. 2 is an exploded view of the fixing device 100 shown in fig. 1. Fig. 3 is an exploded view from another perspective of the fastening device 100 shown in fig. 1. As shown in fig. 1-3, fixture 100 includes a housing 102, a first ring magnet 106, a stationary base 110, a second ring magnet 108, and a spring stud 112. The housing 102 has a tablet housing 101 on a first side between which the tablet 103 may be housed, the housing 102 providing the tablet 103 with the water resistance and biocompatibility required in a medical setting. The housing 102 has a recess 122 on a second face opposite the first face, the wall 124 of the recess 122 having at least one locating hole 128, the recess 122 having a first boss 125. The fixing base 110 has a second boss 115 fitted with the recess 122, and a hole 113 and a third boss 119 provided on the second boss 115. The stationary base 110 may be mounted integral to a housing 116 or other device of a medical instrument, such as a CT gantry, using access screws 118 and holes 120.

Fig. 4 is a rear view of the fixing device 100 shown in fig. 1. Fig. 5 is a cross-sectional view along line AA of the fastening device 100 shown in fig. 4. Fig. 6 is an enlarged view of the area of fig. 5. As shown in fig. 6, the first ring magnet 106 is sleeved on the first boss 125. The second ring magnet 108 is sleeved on the third boss 119 and attracted to the first ring magnet 106. Spring pin 112 is disposed in hole 113 and can spring into or out of locating hole 128.

When the tablet computer 103 is used, the tablet computer 103 can be nested or buckled in the tablet computer accommodating part 101 of the shell 102, the shell 102 is close to the fixed base 110, and the first annular magnet 106 and the second annular magnet 108 are respectively arranged on the shell 102 and the fixed base 110, so that the tablet computer 103 can be fixed by means of the attraction force of the magnets. By virtue of the centering feature of the ring magnet, the fixture 100 can be precisely positioned without requiring additional alignment of the mounting location by the user. The mechanical engagement between the second protrusion 115 of the stationary base 110 and the recess 122 of the housing 102 limits the relative positions of the tablet computer 103 and the stationary base 110, and also provides a second fixation in addition to magnetic attraction.

The position of the positioning hole 128 can be set according to requirements, for example, one positioning hole is arranged every 90 degrees from 0 degree. The positioning ball of the spring stud 112 springs out when it fits into the positioning hole 128 and is pressed back when it is in the other position when the angle needs to be adjusted. The arrangement of the spring pins 112 and the positioning holes 128 enables the tablet computer 103 to rotate at any angle on the fixing base 110 and to be locked at a designated position, and can also well support the horizontal screen and vertical screen display modes of the tablet computer 103. The adjustment of the angle can be directly completed when the tablet computer 103 is placed, or the rotation adjustment can be performed after the tablet computer 103 is placed on the fixed base 110, without being taken down again and then put on, or without being taken down and replaced after replacing parts.

To reduce resistance to rotation of housing 102 relative to spring stud 112, recess 126 may be provided in wall 124 of recess 122, with locating hole 128 being provided in recess 126.

The second boss 115 may have a chamfer 117 to assist in guiding the positioning.

In order to charge the tablet computer 103, the fixing base 110 may have a second recess 121, and the fixing device 100 further includes a first coil 104 and a second coil 114, the first coil 104 is located in the recess 122, and the second coil 114 is located in the second recess 121. When the tablet computer 103 is placed on the fixing device 100, the fixing device 100 automatically charges the tablet computer 103. Under the non-contact charging mode, the charging device can not generate mechanical abrasion similar to a contact, and meanwhile, the equipment can reach higher dustproof and waterproof grade, even completely dustproof and waterproof. The characteristic of the annular magnet to the center can assist in aligning the transmitting coil and the receiving coil which are charged wirelessly, so that the charging transmission efficiency is improved.

According to another aspect of the present invention, a medical apparatus is provided, comprising a housing 116, a tablet computer 103 and a fixing device 100. The tablet computer 103 can be accommodated in the tablet computer accommodating portion 101, and the fixing base 110 is fixed to the housing 116. The medical instrument may be a CT machine, an X-ray machine, a magnetic resonance device or a C-arm.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
