The present invention relates to a medical aid for intestine examinations that may improve the reliability of an examination by accurately and easily identifying a pass time of an intestine according to lapse of time when the motility of the intestine is examined, thereby achieving an accurate diagnosis and an accurate prescription.
A large intestine is a tubular organ that corresponds to a final part of a gastrointestinal tract starting from the appendix and ending at the anal passage, and is a part in which diseases such as colitis ulcerativa, local colitis, and polypus are caused.
Generally, in order to accurately examine the state of a large intestine by using X-rays, a contrast medium that may form a proper contrast against surrounding body tissues are injected for X-ray photographing.
Meanwhile, medical aids for photographing and measuring the motility of an intestine of the constipation patients or the patients whose intestine motilities deteriorate with radioactive rays have been suggested, and the medical aids are materials that are not biodegraded in the human body, are not harmful to the human body, maintain the properties and forms thereof from the initial state after being taken, and do not change even in the case of defecation after a long-time stay in the large intestine, and are taken for three days at an interval of 24 hours after they are taken at the first time and the medical aids left after radioactive photographing measured after four to seven days.
However, the medical aids according to the related art are simple and uniform so that the shapes for dates when the medical aids are taken cannot be discriminated. That is, because the conventional medical aids are concealed according to the shapes and sizes thereof when they are photographed and are photographed while the shapes thereof are the same, they cannot be individually identified so that an accurate measurement according to the intestine pass time is difficult.

Hereinafter, a medical aid for intestine examinations according to a preferred embodiment of the present invention will be described with reference to
As illustrated in
The recording/measuring members 100 are formed by mixing powder of a polymeric composite, such as polyethylene, and powder of barium sulfate (BaSO4), which is a radioactive opaque material that is not harmful to the human body, at a weight ratio of 4:6 to 6:4, preferably, at a weight ratio of 5:4.5 and forming the recording/measuring members 100 into a specific form through heating, injection-molding and/or extrusion.
Here, when the ratio of the polymeric composite powder is less than 4 or the ratio of the barium sulfate powder exceeds 6, the formation performance of the recording/measuring members 100 is not good, and when the ratio of the polymeric composite powder exceeds 6 or the ratio of the barium sulfate powder is less than 4, the readability (discrimination) deteriorates.
According to the present invention, it is preferable that the ratio of the powder of a polymeric composite of polyethylene and the powder of barium sulfate (BaSO4), which is a radioactive opaque material that is not harmful to the human body, be 5.5:4.5 in consideration of the formation performance and readability (discrimination).
Each of the recording/measuring members 100 includes an annular recording body 110 formed through injection-molding or extrusion and cutting, a ball-shaped recording body 120 formed through extrusion, and a polyhedral recording body 130 formed through injection-molding or extrusion and cutting. Here, the injection-molding is achieved by manufacturing the recording/measuring members 100 while maintaining the external shapes thereof such that the sizes and shapes of the recording/measuring members 100 correspond to the original sizes and shapes thereof, and the recording/measuring members 100 are manufactured into the original sizes thereof by extruding the material into the shapes of a rod and cutting the rod by a specific length.
Although
Further, although the ball-shaped recording body 120 is a sphere, any circular sectional shape including an elliptical shape and accommodated in the space in the circular ring of the annular recording body 110 is possible.
Next, although it is most preferable that the polygonal recording body 130 is a hexahedron, any polyhedral shape, such as an octahedron, a dodecahedron, or a polyhedral shape having a section of star shape, having corner angles on the outside thereof is possible. Here, it is preferable that the contour of the outer line of the polyhedral recording body 130 be viewed clearly when the polyhedral recording body 130 is overlaid with the ball-shaped recording body, by making the size of the polyhedral recording body 130 large enough to be accommodated in the space in the circular ring.
In a description of the sizes of the annular recording body 110, the ball-shaped recording body 120, and the polyhedral recording body 130 constituting the recording/measuring member 100, as illustrated in
That is, the recording/measuring member 100 has the size differences, and thus even though the recording/measuring member 100 is overlaid in any direction, in particular, even though the recording/measuring member 100 is overlaid on a plane as illustrated in
Next, the polymeric composite of polyethylene is polyethylene (C2H4(C2H4)n), and polyethylene (C2H4(C2H4)n) has no impurities and has no harmful property, is strong to the acidity of digestive juice, and has a melting point of 132 to 135° C. Then, it is preferable that the polymeric composite of polyethylene be LDPE.
The biodegradable accommodation body 200 is a material that is not harmful to the human body and may be biodegraded after being taken. In other words, the biodegradable accommodation body 200 refers to a capsule that is well known in the medical field and may be sufficiently understood by an ordinary person skilled in the art, and thus a detailed description thereof will be omitted. Because 20 to 24 pills of the recording/measuring members 200 are generally taken by the patient, the patient may easily take the recording/measuring members 200 through the biodegradable accommodation body 200 without feeling foreign substances.
The biodegradable accommodation body 200 is biodegraded if reaching the intestine through the esophagus, and the recording/measuring members 100 accommodated therein are introduced into the small intestine and the large intestine while the forms thereof is maintained.
If about twenty to twenty four recording/measuring members 100 are taken at an interval of twenty four hours for three days, for example, in the sequence of the annular recording body 110, the ball-shaped recording body 120, and the polyhedral recording body 130 in order to examine the motility of an intestine by using the medical aid for intestine examination according to the present invention, the examination of the intestine, for example, the motility of the intestine or constipation may be recognized by identifying at which location of the intestine which recording/measuring member is located as illustrated in
The medical aid for intestine examinations according to the present invention may improve the reliability of an examination by accurately and easily identifying a pass time of an intestine according to lapse of time when the motility of the intestine is examined, and accordingly, an accurate diagnosis and an accurate prescription may be achieved.
The embodiments described in the specification and the accompanying drawings are provided simply to exemplarily describe a part of the technical spirit of the present invention. Accordingly, because the embodiments disclosed in the specification are provided not to limit but to describe the technical spirit of the present invention, it is apparent that the scope of the technical spirit of the present invention is not limited by the embodiments.
