Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a bed board, an examination bed assembly and a computed tomography imaging device.
Background
Computed Tomography (CT) uses a precisely collimated X-ray beam, gamma rays, ultrasonic waves, etc. to scan a cross section of a certain part of a human body one by one together with a detector having a very high sensitivity, has the characteristics of fast scanning time, clear images, etc., and can be used for the examination of various diseases. Depending on the radiation used, computed tomography scans can be classified as: x-ray computed tomography (X-CT), Ultrasound Computed Tomography (UCT), and gamma-ray computed tomography (gamma-CT), among others.
The bed board is an important part of the computed tomography imaging equipment, not only plays a role in bearing load, but also has a great influence on the image quality due to the ray transmission performance. At present, the bed plate is generally made of a single carbon fiber material, and materials such as high-strength foam and the like are added inside the bed plate to improve the bearing capacity. The upper surface and the lower surface of the bed board are both made of carbon fiber prepreg and are molded at high temperature by mould pressing.
There are often rescue phenomena in diagnosis, such as electrical shock cardiac rescue. It is currently generally required that the bed board can withstand high voltages (e.g., 4000 volts). However, the voltage resistance of the carbon fiber is limited, and how to improve the voltage resistance of the bed board is a technical problem yet to be solved.
In addition, carbon fiber is expensive, which results in a bed board with a high price.
Disclosure of Invention
The embodiment of the invention provides a bed plate, an inspection bed assembly and a computer tomography imaging device.
The technical scheme of the embodiment of the invention comprises the following steps:
a couch for computed tomography comprising:
a first region comprising carbon fibers or a composite material made using carbon fibers;
and a second region comprising continuous basalt fibers or a composite material prepared using continuous basalt fibers.
Therefore, the embodiment of the invention overcomes the thinking set that the bed board is made of a single material, and different materials are respectively adopted to form different areas of the bed board, so that the high voltage resistance of continuous basalt fibers can be utilized to improve the voltage resistance of the bed board, and the safety of the bed board is improved.
Moreover, compared with carbon fiber, the continuous basalt fiber has obvious cost advantage, and the embodiment of the invention can also reduce the cost of the bed board.
In one embodiment, the first region is a computed tomography region and the second region is a non-computed tomography region.
Therefore, in the embodiment of the invention, the carbon fiber or the composite material thereof with good imaging capability is adopted to form the computed tomography area so as to ensure the imaging quality, and the continuous basalt fiber or the composite material thereof with good voltage resistance property is adopted to form the non-computed tomography area so as to improve the voltage resistance of the bed board, so that the imaging capability and the voltage resistance of the bed board can be simultaneously ensured.
In one embodiment, the first region comprises:
a first carbon fiber layer arranged on the upper surface of the bed plate and containing carbon fibers or a composite material prepared from the carbon fibers;
the second carbon fiber layer is arranged on the lower surface of the bed plate and comprises carbon fibers or a composite material prepared from the carbon fibers;
a high strength foam layer disposed between the first carbon fiber layer and the second carbon fiber layer.
Therefore, by the structural arrangement of the carbon fiber layer and the high-strength foam layer, not only can the imaging capability of the first region be ensured, but also the manufacturing cost of the first region is reduced.
In one embodiment, the first carbon fiber layer and the second carbon fiber layer are carbon fiber cloth.
In one embodiment, the second region comprises:
the first continuous basalt fiber layer is arranged on the upper surface of the bed plate and contains continuous basalt fibers or a composite material prepared from the continuous basalt fibers;
the second continuous basalt fiber layer is arranged on the lower surface of the bed plate and contains continuous basalt fibers or a composite material prepared from the continuous basalt fibers;
one or more embedded parts arranged between the first continuous basalt fiber layer and the second continuous basalt fiber layer along the horizontal direction of the bed board;
one or more high strength foams are arranged between the first continuous basalt fiber layer and the second continuous basalt fiber layer along the horizontal direction of the bed board in a staggered mode with the one or more embedded parts.
Therefore, by arranging the embedment in the second region, the strength and rigidity of the second region are improved. In addition, the anti-vibration capability of the second area can be improved by using the high-strength foam staggered with the embedded parts, and the manufacturing cost of the second area is saved.
In one embodiment, further comprising:
the first composite layer comprises carbon fiber layers and continuous basalt fiber layers which are arranged in a staggered mode in the height direction of the bed board; wherein the first composite layer is disposed between a first continuous basalt fiber layer and an upper surface of the embedment;
and the second composite layer comprises carbon fiber layers and continuous basalt fiber layers which are arranged in a staggered mode in the height direction of the bed board, wherein the second composite layer is arranged between the second continuous basalt fiber layer and the lower surface of the embedded part.
In one embodiment, the first continuous basalt fiber layer is a multi-axial continuous basalt fiber cloth, and the second continuous basalt fiber layer is a multi-axial continuous basalt fiber cloth.
It can be seen that, by implementing the staggered arrangement of the continuous basalt fiber layer and the carbon fiber layer in the second area, the voltage resistance of the second area can be improved by using the basalt fiber layer, and the bearing capacity of the second area can also be improved by using the carbon fiber layer.
In one embodiment, the thickness of each of the first and second continuous basalt fiber layers is 0.4 millimeters.
An examination table assembly for computed tomography comprising:
a bed deck comprising a first region comprising carbon fibers or a composite made using carbon fibers and a second region comprising continuous basalt fibers or a composite made using continuous basalt fibers;
a linear guide rail;
and the horizontal sliding mechanism is arranged at the lower part of the second area and is adapted to slide on the linear guide rail.
It can be seen that, by the second region disposed at the lower portion of the horizontal sliding mechanism, the horizontal sliding mechanism can be prevented from leaking electricity at the time of high voltage. Furthermore, by including the carbon fiber or the first region of the composite material made using the carbon fiber, it is also possible to ensure the imaging quality.

Detailed Description
In order to make the technical scheme and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
For simplicity and clarity of description, the invention will be described below by describing several representative embodiments. Numerous details of the embodiments are set forth only to assist in understanding the aspects of the invention. It will be apparent, however, that the invention may be practiced without these specific details. Some embodiments are not described in detail, but rather are merely provided as frameworks, in order to avoid unnecessarily obscuring aspects of the invention. Hereinafter, "including" means "including but not limited to", "according to … …" means "at least according to … …, but not limited to … … only". In view of the language convention of chinese, the following description, when it does not specifically state the number of a component, means that the component may be one or more, or may be understood as at least one.
The bed board has a severe dual requirement for imaging capability (mainly depending on the ray penetration performance of the bed board) and voltage resistance capability. If the bed board is made of carbon fiber, the voltage resistance of the bed board is difficult to ensure; if the bed board is made of voltage-resistant materials, the imaging capability of the bed board is difficult to guarantee.
The applicant found that: if the thinking set that the bed board is made of a single material is overcome, and different materials with high voltage resistance and high imaging capability are respectively adopted to form different areas of the bed board, the imaging capability and the voltage resistance of the bed board can be simultaneously ensured.
Fig. 1 is a schematic view of a couch top for computed tomography according to an embodiment of the present invention.
As shown in fig. 1, the deck 100 includes:
a first region 101 comprising Carbon Fibers (CF) or a composite material prepared using Carbon Fibers (CFK);
the second zone 102, contains Continuous Basalt Fibers (CBF) or composites made with Continuous Basalt fibers.
Wherein the first region 101 may comprise carbon fibers. The carbon fiber is a high-strength and high-modulus fiber material with the carbon content of more than 95%. The carbon fiber is a microcrystalline graphite material obtained by stacking organic fibers such as flaky graphite microcrystals along the axial direction of the fiber and performing carbonization and graphitization treatment. The carbon fiber has good radiation transmissivity, and thus the first region 101 including the carbon fiber has good radiation transmissivity.
The first region 101 may also comprise a composite material made with carbon fibers. For example, carbon fibers are added as a reinforcing material to a material such as resin, metal, ceramic, or concrete, thereby forming a carbon fiber-reinforced composite material. The carbon fibre reinforced composite material also has good radio-transparency and therefore the first region 101 of the composite material comprising carbon fibres also has good radio-transparency.
It can be seen that the first region 101 comprises carbon fibers or a composite material made from carbon fibers, and therefore the first region has good radiolucency. Preferably, the first region 101 is implemented as a computed tomography region. The imaging target is placed in the first region 101 implemented as a computed tomography region, and the imaging quality of the imaging target can be improved.
The second region 102 may contain continuous basalt fibers. The continuous basalt fiber is formed by melting basalt stone at 1450-1500 ℃ and drawing the molten basalt stone through a platinum-rhodium alloy wire drawing bushing plate, and the strength of the continuous basalt fiber is equivalent to that of high-strength S glass fiber. The continuous basalt fiber has high strength, and also has various excellent performances of electrical insulation, corrosion resistance, high temperature resistance and the like. In particular, the continuous basalt fiber has good voltage resistance properties, and thus the second region 102 including the continuous basalt fiber has good voltage resistance capability.
The second region 102 may also comprise a composite material prepared using continuous basalt fibers. For example, the continuous basalt fiber reinforced composite material can be formed by adding the continuous basalt fiber as a reinforcing material into materials such as resin, metal, ceramic, concrete and the like. The continuous basalt fiber reinforced composite material has good voltage resistance properties, so the second region 102 of the composite material prepared from the continuous basalt fiber also has good voltage resistance.
It can be seen that the second region 102 includes continuous basalt fibers or a composite material using continuous basalt fibers, and thus the second region 102 has good voltage resistance. Preferably, the second region 102 is implemented as a non-computed tomography region. The imaging target is typically not placed in the second region 102 to avoid poor imaging quality. The second region 102, which is a part of the bed board 100, can significantly improve the voltage resistance of the bed board 100. For example, the horizontal sliding mechanism under the top board 100 is usually made of metal, and leakage of electricity is likely to occur at high voltage. The second region 102 is disposed at the upper portion of the horizontal sliding mechanism below the bed plate 100, which can prevent the horizontal sliding mechanism from leaking electricity at high voltage.
An exemplary structure of the second region 102 is described in detail below.
Fig. 2 is a first exemplary cross-sectional view of the second region 102 of fig. 1, wherein the direction of the deck height is shown in dashed lines.
As shown in fig. 2, the second region 102 includes:
a first continuous basalt fiber layer 201, which is arranged on the upper surface of the bed plate 100, and contains continuous basalt fibers or a composite material prepared from the continuous basalt fibers;
a second continuous basalt fiber layer 204, which is arranged on the lower surface of the bed plate 100, and contains continuous basalt fibers or a composite material prepared from the continuous basalt fibers;
one or more embedded parts 203 which are arranged between the first continuous basalt fiber layer 201 and the second continuous basalt fiber layer 204 at intervals along the horizontal direction of the bed board;
one or more high strength foams 202 are arranged between the first continuous basalt fiber layer 201 and the second continuous basalt fiber layer 204 in a staggered manner with one or more embedments 203 in the horizontal direction of the bed plate.
Wherein the embedment 203 may function as a stiffener to increase the strength and rigidity of the second region 102. The high strength foam 202 has a low modulus of elasticity that provides good absorption and dispersion of shock impact loads, thereby increasing the shock resistance of the second region 102. At the same time, the high strength foam 202 may also significantly reduce the quality of the second region 102 and save the manufacturing cost of the second region 102.
In one embodiment, the first continuous basalt fiber layer 201 is implemented as a multi-axial continuous basalt fiber cloth, such as a bi-axial continuous basalt fiber cloth or a tri-axial continuous basalt fiber cloth.
