Description

Technical Field

[0001] The utility model relates to the field of X-ray machines, in particular to a portable X-ray machine. Background Art

[0002] As a commonly used medical device, X-ray machine mainly utilizes the penetration, differential absorption, photosensitivity and fluorescence of X-rays. Since X-rays are absorbed to different degrees when passing through the human body, they carry information about the density distribution of various parts of the human body. The intensity of the fluorescence or photosensitivity caused on the fluorescent screen or photographic film varies greatly, so shadows of different densities will be displayed on the fluorescent screen or photographic film, and then the human body can be diagnosed through analysis and comparison.

[0003] The X-ray machines currently in use are generally large in size and require a special radiation room. However, when used clinically, X-ray imaging is often performed on human hands, arms, feet and other limbs, or body parts with lower attenuation. The use of large X-ray machines will result in a relatively large radiation dose, which will increase the radiation dose for patients or the public.

[0004] Moreover, when encountering rescue situations, large X-ray machines cannot be carried and used, which means that it is impossible to perform emergency diagnosis on patients during rescue, avoiding the possibility of secondary injury to patients. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] As shown in FIG. 1 , the present embodiment provides a portable X-ray machine, including a main unit 1. A handle is integrally provided on one side of the main unit 1 to facilitate the taking and use of the main unit. A lithium battery and a high-voltage tube are provided inside the main unit. The high-voltage tube is an X-ray high-voltage generator. The battery is a DC power supply of 22.2V, and the battery capacity is at least 2200mh. A power button 2 and a USB connection port are provided on the upper side of the main unit 1. The USB connection port includes a USB2.0 port 4 and a USB3.0 port 5. Both USB ports can be connected to a user digital image connector sensor. Due to displaying or exporting images, specifically, Figure 1 and Figure 2 shown.

[0027] The rear side of the host 1 is provided with an LCD display 6 and a manual switch jack, and the LCD display 6 is used to set and display parameters. The manual switch jack is connected to the manual exposure gate for manual exposure. A charger jack is also provided at the bottom of the rear side of the host 1 for connecting a charging cable to charge the lithium battery. The power adapter is selected to have an input single phase, AC 220V±10%, an output DC25.2V, 1.5A, and a charging frequency of the power supply is: 50Hz±1Hz.

[0028] An X-ray release button 7 is provided at the upper corner of the front side of the host 1. Pressing this button can release X-rays. An X-ray output window 8 is provided on the rear side of the host 1, and X-rays can be emitted from the X-ray output window 8.

[0029] The device is powered by a lithium battery. Since the object of use is the body parts and tissues with relatively low attenuation such as the limbs of the human body, the volume of the high-voltage tube does not need to be set too large. The overall structure is relatively small, only 285mm x 265mm x168mm long × wide × high, and the overall weight is 3.2kg±5%.

[0030] Working temperature: 10℃~40℃;

[0031] Working humidity 30%~75% without condensation;

[0032] Working atmospheric pressure 700hPa~1060hPa;

[0033] Storage and transportation temperature: -10℃~50℃;

[0034] Storage and transportation humidity 10% ~ 93%;

[0035] Storage and transportation atmospheric pressure 700hPa~1060hPa.

[0036] The specific human absorption dose is as follows:

[0038]

[0039] Note: SID = 30cm, unit: uGy.m 2

[0040] Baffles 9 are also provided on both sides of the X-ray output window 8, and the baffles can be removed from both sides of the X-ray output window 8. It should be noted that the baffles 9 do not need to be installed every time they are used, and are only used when the minimum distance between the X-ray focus and the patient is more than 200 mm, which can reduce the spillover of X-rays.

[0041] like Figure 3 and Figure 4 As shown, a T-shaped slide bar 91 is fixedly installed on both sides of the X-ray output window 8, and the bottom of the slide bar 91 is set as a convex portion protruding outward, such as Figure 3 As shown. A limit block 93 is fixedly installed on the outer bottom of the slide bar 91. Figure 4 As shown, one end of the baffle 9 is provided with a slide groove 92 with a bottom opening, and the slide groove 92 is a T-shaped structure. Accordingly, an expansion groove corresponding to the protrusion is provided at the bottom of the slide groove 92, and a limiting groove is provided on the bottom side wall of the slide groove 92. The baffle 9 can be pressed downward from the upper end of the slide bar 91, so that the slide groove 92 slides downward from the outside of the slide bar 91 and is engaged with the slide groove 91. When the baffle 9 slides to the bottom, the limiting block 93 is engaged with the limiting groove, and the installation of the baffle 9 is completed.

[0042] In this embodiment, in order to facilitate the installation of the baffle 9, the upper end of the limit block 93 is a downwardly inclined slope structure. When installing the baffle 9, the slide groove 92 deforms outward along the slope, so that the limit block 93 and the limit groove are engaged together. When removing the baffle 9, it is only necessary to push the bottom of the baffle 9 outward to separate the limit block 93 from the limit groove, and then the baffle 9 can be removed upward.

[0043] When the baffle 9 is set separately from the host 1, since the baffle 9 is set separately, the baffle 9 needs to be placed outside, which may easily cause the baffle 9 to fall or be lost. Therefore, in a further embodiment, the baffle 9 and the X-ray output window 8 may also be set as a structure together to facilitate the use and placement of the baffle 9.

[0044] like Figure 5 and Figure 6As shown, rotating seats are fixedly installed on both sides of the edge of the X-ray output window 8, and a rotating shaft is fixedly installed on the baffle 9. The rotating shaft is rotatably installed in the rotating seat, and the baffle 9 can rotate on the rotating seat. There is friction or damping force between the rotating shaft and the rotating seat. When the baffle 9 is not subjected to external force, it will not rotate under the action of friction or damping force. When the baffle 9 is not in use, the baffle 9 can rotate backward on the rotating seat and fit together with the side of the main unit 1. The baffle 9 and the X-ray output window 8 are set as a structure together. The baffle 9 rotates backward when not in use, and can be rotated to the front sides of the X-ray output window 8 when in use. The baffle 9 and the main unit 1 can be fixed together to prevent the baffle 9 from shaking when in use. In addition, the baffle 9 can be removed, which is more convenient for the use of the baffle 9.

[0045] In one embodiment, Figure 6 As shown, a block 10 is fixedly installed at the edge of one end of the baffle 9 that contacts the host 1, and a slot 11 matching the block 10 is provided on the side of the host 1. When the baffle 9 rotates backward to contact the host 1, the block 10 and the slot 11 are engaged together. At this time, the baffle 9 is located at the side wall of the X-ray output window 8 and the host 1, and also plays a protective role for the connection between the X-ray output window 8 and the host 1.

[0046] It should be noted that when the battery bar shows only two bars, the X-ray cannot be released. This means that the battery is too low and it may shut down unexpectedly, and unexpected termination will damage the system.

[0047] When using it, it is recommended to use a manual switch. When the operator uses the manual switch, the exposure dose will be significantly reduced. The operator should release the X-ray diagonally 2 meters behind the equipment instead of exposing it in a straight line. Figure 7 Shown
