Description

 The present invention relates to a venous fluoroscope used for intravenous injection and the like that facilitates gripping during use and allows good contact with a subject's hand.

  In general, blood collection or injection may be difficult because the size, curvature, and branching of blood vessels in tissues under the skin of a human body vary from person to person. Although some veins can be seen visually, the position of the veins under the skin of the human body is relatively deep and thin, so it is difficult to find and requires skill to find the position of the blood vessels, especially the fat layer compared Thick patients are often unable to find blood vessels and may be blind and pierced with an injection needle, or the needle may be improperly inserted. The present inventor has invented and proposed the “blood vessel image searcher” patent (new type M261175) and the “blood vessel image searcher” patent (new type M268000). The patented technology uses an LED red light source with an emission wavelength of 600 to 650 nm and a xenon bulb (or a tungsten bulb or a red filter together) as a light source to search and clarify veins or blood vessels in the vicinity of the body surface and collect blood. Or, the injection into the vein of the correct needle at the time of injection was made possible.

 However, the above conventional techniques still have inconveniences that there are still insufficient portions in use, it is difficult to hold by the user's hand, and contact with the subject's hand is uncertain.

  An object of the present invention is to provide a venous fluoroscope that improves the fluoroscopy of the veins by making the comfortable and light feeling at the same time and at the same time making the contact between the light irradiation area and the human hand part stable and reliable.

  Another object of the present invention is to achieve the effect of enhancing optical fluoroscopy and improve vein fluoroscopy by using different wavelengths of 590 to 660 nm in combination with the light source of the vein fluoroscope.

  In order to achieve the above object, the vein fluoroscopic device of the present invention is an image fluoroscopy device that is composed of components such as a fluoroscopic main body and an irradiation unit, and generates an image light source. The irradiation unit is incorporated in the main body of the fluoroscopic device. It is composed of at least components such as a power source, a circuit board, a plurality of light emitting diodes, and an aperture adjuster, and further, a light irradiation region exposed to the outside is formed on the fluoroscope main body. It is formed in a form that curves in response to a human hand, and is in the form of a brush shape, a spherical shape, a gear lever shape, etc., and an arc-shaped gripping portion is formed on the opposite outer edge, and at the same time, the irradiation unit The light irradiation area is installed at a desired location adjacent to the gripping portion, and an arc lamp shade is provided on the outer edge of the light irradiation area. The light emitting diode of the irradiation unit generates a light source composed of a combination of independent wavelengths or different wavelengths of 590 to 660 nm, and in different skin colors, the size, curvature, and venous blood vessels of the subcutaneous tissue on the back of the patient's hand The branch state can be clarified.

 According to the present invention, the gripping portion of the fluoroscope main body and the arc-shaped lamp shade are adapted to the structure of ergonomics to improve the tightness of contact with the hand of the subject and to mix light emitting diodes of different wavelengths. The effect can be used to promote the clarification effect of venous blood vessels.

  Embodiments of the present invention will be described below with reference to the drawings.

 As shown in FIG. 1 to FIG. 13, the hand-held vein fluoroscope 1 according to the embodiment of the present invention is composed of constituent members such as a fluoroscope main body 10 and an irradiation unit 20.

  The fluoroscope main body 10 is an outer shell of the image fluoroscope 1 and is formed in a structural form so as to be adapted to human body engineering and accurately corresponds to a curved structure of a human hand. Arc-shaped gripping portions 11 are formed at opposite locations. The fluoroscope main body 10 has a spherical shape (see FIGS. 1 to 3 and 9 to 13), a brush shape (see FIGS. 4 and 5), a gear lever shape (see FIGS. 6 and 7), and the like. Can do. They only have a difference in the change in outline, and the substantial structure is the same. The detailed structure form of the gripping part 11 of each embodiment will be described later. Therefore, the fluoroscope main body 10 and the irradiation unit 20 will be described first in a spherical example.

  As shown in FIG. 2, the irradiation unit 20 is incorporated in the fluoroscope main body 10 and includes at least components such as a power source 21, a circuit board 22, a plurality of light emitting diodes 23, and an aperture adjuster 24. .
