1. Field of the Invention
The present invention relates to warm-keeping apparatus and more specifically, to a body warn-keeping apparatus for keeping the core temperature of an object during an X-ray examination.
2. Description of the Related Art
When making an X-ray examination, the core temperature of the object to be X-rayed may have to be kept. For example, when a premature or weak baby is going to receive an X-ray examination, a medical person may cover a blanket on the patient or put a blanket on the platform beneath the patient to kept the body of the patient warm, avoiding the patient losing temperature that may risk the patient's life.
However, a blanket does not provide excellent warm-keeping effect, and is difficult to wash. After one use, the blanket may be discarded. Therefore, using a blanket to keep a patient warm during an X-ray examination is not an economic way. Further, a premature or weak baby or a temperature-losing patient shall have to be kept in an infant incubator/medical bed that keeps the core temperature of the baby/temperature-losing patient stable.
When a temperature-losing patient is going to receive an X-ray examination, the patient must be delivered from the medical bed to the X-ray system. It is difficult to move the patient from the medical bed to the X-ray system. This procedure takes much time and labor, and causes inconvenience to medical persons. To a temperature-losing patient carrying a life-support system, the problem will get worse, and the X-ray examination may be unable to perform on time, wasting precious time.
Further, when a premature baby is going to receive an X-ray examination, the medical person needs to carry the premature baby from the infant incubator to the platform of the X-ray machine. After the examination, the medical person needs to carry the premature baby from the platform of the X-ray machine back to the infant incubator. This procedure wastes much time and labor, and interferes with the baby's sleep quality. To a baby carrying a life-support system, this procedure not only wastes time and labor but also increases life-threatening risk. Further, the warm-keeping effect of wrapping a premature baby with a blanket is limited.
To avoid the aforesaid problems, a warm-keeping apparatus is known comprising a platform for the placing of a blanket, an X-ray tray provided beneath the platform for holding an X-ray film, and a hot air apparatus adapted for providing hot air to keep the patient warm. This warm-keeping apparatus allows the patient therein to receive an X-ray examination directly without interference, facilitating performance of an X-ray examination rapidly and safely.
To avoid interference with the radiation of X-rays, the arrangement of the hot air apparatus and other devices (life-support device and etc.) is complicated. The arrangement includes an opening in the X-ray radiation path and other complicated structures to avoid blocking X-rays and affecting examination accuracy. Further, the cost of the hot air apparatus is high. The hot air apparatus consumes much energy and causes noises during its operation.
Therefore, it is desirable to provide a body warm-keeping apparatus that eliminates the aforesaid drawbacks and problems.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a body warm-keeping apparatus, which provides excellent body warm-keeping effect and facilitates the performance of X-ray examinations. It is another object of the present invention to provide a body warm-keeping apparatus, which has the parts thereof skillfully arranged, effectively lowering the cost.
To achieve these and other objects of the present invention, the body warm-keeping apparatus is adapted for keeping the core temperature of a human body during an X-ray examination, comprising an apparatus body and at least one heater device. The apparatus body comprises a platform and at least one accommodation compartment disposed at one side relative to the platform. The platform defines a radiation region corresponding to an X-ray radiation path. The at least one accommodation compartment is disposed in the X-ray radiation path, for accommodating a photographic receptor. The at least one heater device is mounted on the radiation region of the platform and kept in contact with the human body receiving an X-ray examination. Each heater device comprises a conducting material and a conducting wire. The conducting material is arranged corresponding to the radiation region. The conducting wire electrically connects a power supply unit to the conducting material, and extends along the border of the conducting material. The conducting material allows penetration of X-rays therethrough for causing the photographic receptor to produce a shadow image of the internal structure of a part of the human body that is kept in contact with the at least one heater device and radiated with X-rays going through the X-ray radiation path.
In conclusion, the heater device of the body warm-keeping apparatus allows penetration of X-rays therethrough, and is arranged on the platform and kept in direct contact with the patient. The layout of the internal conducting wire of the heater device avoids interfering with the patient during an X-ray examination. In addition to excellent warm-keeping effect, the body warm-keeping apparatus of the present invention allows the patient to receive an X-ray examination directly, facilitating medical performance. Further, the design arrangement of the invention is easy, having an industrial value and market competitive power.

The thin-sheet conducting material 21 is a flexible electroheating material that allows penetration of X-rays therethrough. According to this embodiment, the thin-sheet conducting material 21 is prepared from, but not limited to, carbon fiber. Further, the thin-sheet conducting material 21 can be made in, but not limited to, the form of a thin piece of cloth, thin sheet of felt or thin film.
The flexible base material 22 is formed of two flexible thin films that surround the thin-sheet conducting material 21 and allows penetration of X-rays therethrough. The flexible base material 22 supports and protects the thin-sheet conducting material 21.
The warm-keeping bag 23 can be made to detachably wrap the flexible base material 22. Alternatively, the warm-keeping bag 23 can be fixedly fastened to the flexible base material 22. According to this embodiment, the warm-keeping bag 23 is made of a flexible thermal insulation material such as silicon rubber or plastic foam material, and therefore the warm-keeping bag 23 effectively lowers the heat dissipation speed of the thin-sheet conducting material 21, extending the warm-keeping time and saving the energy. However, the warm-keeping bag 23 is not a requisite element and can be omitted. Further, the warm-keeping bag 23 may be wrapped with a layer of waterproof covering material (not shown) to enhance water resistance. For example, the warm-keeping bag 23 can be covered with a layer of waterproof nylon fabric covering to match with the thin-sheet conducting material 21 and the flexible base material 22, so that the heater device 20 imparts comfort to the user and can be washed and kneaded in water without losing its function.
The conducting wire 24 is electrically connected with the thin-sheet conducting material 21 and the power supply unit 101 of the apparatus body 10 to transmits output electric energy from the power supply unit 101 to the thin-sheet conducting material 21, causing the thin-sheet conducting material 21 to produce heat. According to this embodiment, as shown in
The material for the hood 15 allows penetration of X-rays therethrough. According to this embodiment, the hood 15 can be made having ventilation holes or equipped with an air circulation system (not shown) to maintain ventilation. This part is not within the scope of the present invention, no further detailed description in this regard is necessary.
In conclusion, when compared with the use of a blanket according to the prior art, the heater device 20 of the present invention has better warm-keeping effect and is relatively easier to clean. When compared with the use of a hot air equipment according to the prior art, the heater device 20 of the present invention has the advantages of small size, less space occupation, ease of arrangement Furthermore, the heater device 20 allows penetration of X-rays therethrough so that a medical person can directly apply an X-ray examination to the object P without moving the object P from the body warm-keeping apparatus 100, saving much labor and time. Further, the layout of the conducting wire 24 of the heater device 20 is kept away from the area bearing the object P, and therefore the heater device 20 does not interfere with the performance of an X-ray examination that is being applied to the object P. When compared with the arrangement of the conventional hot air equipment, the design and preparation cost of the present invention is relatively cheap, and the body warm-keeping apparatus 100 provides extra space for accommodating other devices to provide added value.
After understanding of the arrangement and relative positions of the component parts of the body warm-keeping apparatus 100, the operation and effects of the body warm-keeping apparatus 100 are outlined hereinafter.
When applying an X-ray examination to the object P in the body warm-keeping apparatus 100, the X-ray source is started to emit X-rays through the hood 15, the object P, the heater device 20 and the platform 11, and the radiation is then received by the photographic receptor 30 to produce an X-ray image after exposure, as shown in
As stated above, the object P is kept in contact with the heater device 20 during an X-ray examination, therefore an excellent warn-keeping effect is obtained. Further, because the heater device 20 has light and thin characteristics and allows penetration of X-rays therethrough, as well as the advantage of the special layout of the conducting wire 24, the arrangement of the heater device 20 in the body warm-keeping apparatus 100 is easy. Therefore, the cost of the body warn-keeping apparatus 100 can be relatively reduced while image quality is maintained. The body warm-keeping apparatus 100 allows a medical person to conveniently apply an X-ray examination to the object P carried therein. Further, the conducting material 21 consumes low power, and therefore the heater device 20 is durable and safe in use, and the matched power supply unit 101 can be a small-sized design. Further, because the body warm-keeping apparatus 100 does not use any pump to provide hot air, the operation of the body warm-keeping apparatus 100 is smooth and making no noise, not interfering with sleep or rest of the object (infant) P.
Any suitable material that allows penetration of X-rays may be provided between the heater device 20 and the object (premature or weak baby) P, preventing from keeping the object (premature or weak baby) P too warm. Further, as shown in
Further, the aforesaid accommodation compartment 13, heater device 20, photographic receptor 30 and radiation region 111 are not limited to one single number. For example, to satisfy the demand for photographing many parts of a premature or weak baby by X-rays at a time, the body warm-keeping apparatus can be made having multiple accommodation compartments for accommodating a respective tray for photographic receptor (photographic film) corresponding to multiple heater devices in multiple radiation regions on the platform of the apparatus body. Alternatively, the body warm-keeping apparatus can be made having one single heater device that can be moved in the platform to one of a number of locations for enabling one of a number of parts of the body of the object being carried on the heater device to be photographed by X-rays. A big area heater device may be used to substitute for a number of relatively smaller heater devices in matching with the multiple accommodation compartments design. Further, the photographic receptor 30 may be directly put in the accommodation compartment 13 without the aforesaid tray 14.
Further, the power supply unit 101 can be a DC battery directly installed in the apparatus body 10, or a discrete DC battery disposed outside the apparatus body 10. DC battery allows the medical person to use the body warm-keeping apparatus 100 conveniently, extending the moving distance and application range of the body warm-keeping apparatus 100. Alternatively, the power supply unit 101 can be a device that outputs AC power supply.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
