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.

Conventional technology Generally, when a bone in an arm or leg is broken, in order to detect the fractured part, an X-ray sensitive film is placed under the arm or leg, and the film is exposed by irradiating Xg through the arm or leg. After this, the film was developed, and the extent of the fracture was determined by visually observing the developed film under illumination.

However, with this conventional method of using film, it takes time and effort to develop the film, so even if a fracture occurs, it is not possible to immediately determine the extent of the fracture, resulting in delayed treatment, and in the case of a compound fracture, it is difficult to determine the extent of the fracture. The ``disadvantage'' was that moving the arm or leg would worsen the fracture and slow recovery.

Systems that directly irradiate X-rays for observation are also known, but it has been reported that irradiating X-rays for a long time or irradiating X-rays of a certain intensity many times can cause radiation damage to a single person. There were drawbacks.

Purpose The present invention has 1. This was developed in order to eliminate the drawbacks of the above-mentioned conventional examples, and its purpose is to provide a fracture detector that has a forward-looking configuration and can immediately detect fractures.

In order to achieve the above-mentioned object, the present invention provides a bag body whose detected portion is sterilized and sealed at both ends, a liquid supply circulation device for depositing and discharging liquid into the bag body, It is characterized by comprising a cylindrical cover provided on the outside of the bag, 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 that does not leak liquid is provided to cover a fractured part of an arm 1, and both ends of this bag body 2 are A tube 4 is connected to the bag body 2, which is fixed to the arm with an adhesive tape 3 or the like, and which prevents liquid from leaking from both ends of the 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 the bag 2, and 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 other end is connected by a locking member 9. The ultrasonic transducer 7 may sequentially receive electrical signals and emit ultrasonic waves, and may sequentially receive the reflected waves from the bones of the arm 1 and display them on the display 10, or may be provided on a portion of the cover 6a. The ultrasonic transducer 7 may be a transmissive type in which the ultrasonic transducer 7 is used as 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 in this way, firstly, the broken part 1, for example, the arm in the embodiment shown in the figure, is covered with the bag body 2, and both ends are securely fixed with adhesive tape 3, etc., and then the cover is The parts 6a and 6b are placed over the bag body 2 and locked with the locking member 9. 9. Liquid supply circulation device 5 to bag body 2
A liquid such as a disinfectant solution is introduced through the tube 4 so that the ultrasonic vibrator 7 and the bag body 2 are in good contact with each other. and,
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 explanation, the liquid was poured into the bag body 2 after the cover parts 6a and 6b were placed over the bag body 2. You can also cover it. Further, the cover 6 is configured in a cylindrical shape.

The ultrasonic transducer 7 may be attached to the inner surface of the J-bar 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 by ultrasonic waves by simply placing an arm or leg inside a bag, and does not harm the human body like an X-ray fluoroscopy system. The advantage is that there is no
