Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a fracture detector, and more particularly to a fracture detector that can easily detect fractures using an ultrasonic transducer.

Prior Art Generally, when a bone in an arm or leg is broken, in order to detect the fractured part, an X-ray photosensitive film is placed under the arm or leg, and X-rays are irradiated through the arm or leg. After exposure, the film was developed, and the developed film was illuminated and visually observed to determine the degree of fracture.

However, with this conventional method of using film, it takes time and effort to develop the film.
Even if a fracture occurs, it is not possible to immediately determine the extent of the fracture, so treatment may be delayed, and in the case of a compound fracture, moving the broken arm or leg may make the fracture worse.
The drawback was that recovery was slow.

Systems that directly irradiate X-rays for observation are also known, but it has been reported that radiation damage can occur in the human body if X-rays are irradiated for a long time or if X-rays of a certain intensity are irradiated many times. There were flaws.

Purpose The present invention has been made in order to eliminate the drawbacks of the above-mentioned conventional examples, and its purpose is to provide a fracture detector that has a simple configuration and is capable of immediately detecting fractures.

Configuration In order to achieve the above object, the present invention provides a bag body that covers a detected part and is sealed at both ends, a liquid supply circulation device that injects and discharges liquid into the bag body, and a liquid supply circulation device for injecting and discharging liquid into the bag body. It is characterized by comprising a cylindrical cover provided on the outside and a plurality of ultrasonic transducers provided in an array inside the cylindrical cover. The configuration will be described below based on embodiments of the present invention.

FIG. 1 shows a cross-sectional view of a fracture detector according to an embodiment of the present invention, in which a bag body 2 is provided to cover a fractured part of an arm 1 and prevent fluid from leaking, and both ends of this bag body 2 are It is fixed to the arm with an adhesive tape 3 or the like, and liquid is prevented from leaking from both ends of the bag body 2. A tube 4 is connected to this bag body 2, and a liquid supply circulation device 5 is connected to this tube. A cylindrical cover 6 is provided on the outside of this bag body 2,
A plurality of ultrasonic transducers 7 are provided in an array along the inner surface of the cover 6.

This cover 6 is divided into two cover parts 6a and 6b as shown in FIG.
The ends of a and 6b are rotatably provided with hinges 8,
The other ends of the cover parts 6a, 6b are connected by a locking member 9. The ultrasonic transducer 7 may be sequentially sent electrical signals to emit ultrasonic waves, and may sequentially receive reflected waves from the bones of the arm 1 and display them on the display 10, or may be provided on the cover portion 6a. The ultrasonic transducer 7 may be a transmissive type in which the ultrasonic transducer 7 is an ultrasonic transmitting element, and the ultrasonic transducer 7 provided on the cover portion 6b is an ultrasonic receiving element.

In the fracture detector of this embodiment configured as described above, the bag body 2 is first placed over the fractured part, for example, the arm in the illustrated embodiment, and both ends are securely fixed with adhesive tape 3 or the like. Next, cover parts 6a and 6b are attached to the bag body 2.
Place it over the top and lock it with the locking member 9. Then, the tube 4 is connected to the bag body 2 from the liquid supply circulation device 5.
Put liquid such as disinfectant through the ultrasonic vibrator 7.
and the bag body 2 should be in good contact with each other. Then, by sequentially operating the ultrasound transducer 7 in a reflection type or a transmission type, a fracture can be displayed on the display 10.

Since this embodiment can easily display fractures in this way, it is possible to quickly treat fractures.

In addition, in the above description, the cover parts 6a, 6b
After putting the liquid on the bag body 2, the liquid was poured into the bag body 2. However, after pouring the liquid into the bag body, the cover part 6a,
6b may be covered. Alternatively, the cover 6 may be configured in a cylindrical shape, the ultrasonic transducer 7 may be attached to the inner surface of the cover 6, and the outer surface of the bag body 2 may be adhered to the inner surface of the ultrasonic transducer 7.

Effects As is clear from the above explanation, the present invention allows fractures to be easily detected using ultrasonic waves by simply placing an arm or leg inside the bag. It has the advantage of being harmless.
