Abstract
The present invention provides one kind of auxiliary medical equipment to show vein directly on the surface of skin. The technological scheme includes vein projector comprising infrared light source, infrared video camera, infrared reflector and projecting unit. The infrared reflector in the projector optical path reflects infrared light while transmitting green and blue light, and is in such angle that it refracts the infrared image to the infrared video camera. The taking angle and projecting angle are coincided, and projector has green and blue light source to make the imaging device display green and blue image. The projector lens projects the green and blue image onto the hand back where the infrared image is taken without inferring the distinction of the infrared video camera to the veins.
Description
The present invention relates to a kind of auxiliary medical equipment.
Venipuncture is the medication of using always, but the vein under the skin is difficult to differentiate only according to naked eyes, and operation easier is big.
The purpose of this invention is to provide a kind of equipment that can make the vein image directly be apparent in skin surface.
The present invention is by infrared light supply, infrared camera, ir reflector and projector form, it is characterized by: venous projecting apparatus is by infrared light supply, infrared camera, ir reflector and projector form, wherein infrared light supply is some respectively to the infrared LED of the back of the hand and palm of the hand direction irradiation, ir reflector in the venous projecting apparatus light path reflects as mirror for infrared light, for turquoise coloured light then is transparent, and the mode of the infrared image that vein can can't be seen with naked eyes under skin of dorsum of hand under the irradiation of infrared light supply displays; Ir reflector is refracted to infrared camera to infrared image with appropriate angle, shooting angle and crevice projection angle are overlapped, infrared camera identifies infrared image signal is passed to image device in the projector, image device demonstrates image, light source of projector is the turquoise light source, image device in the turquoise light source irradiation projector, the image that image device is demonstrated becomes the turquoise image, the turquoise image projection that projector lens demonstrates image device is at the skin surface of the captured the back of the hand of infrared camera, because turquoise coloured light can not discerned by infrared camera, the turquoise image that the machine that is not projected projects so guaranteed infrared camera only to discern vein on hand disturbs.Ir reflector in the venous projecting apparatus light path and infrared camera can be installed between the camera lens and image device in the projector, the hand back vein infrared image is refracted to infrared camera later on by the ir reflector that projector lens is transmitted in the projector, and the turquoise image that image device demonstrates then passes ir reflector and projects on the back of the hand by projector lens; Ir reflector in the venous projecting apparatus light path and infrared camera also can be installed in camera lens below outside the projector, infrared camera and projector install with an angle of 90 degrees, ir reflector is installed with miter angle between infrared camera and projector, making the hand back vein infrared image be projected the turquoise image for infrared camera, projector by the infrared external reflection mirror reflection then passes ir reflector and projects on the back of the hand; Light source of projector is green, blue high-brightness LED, also can be that other white light sources add green. the formed green of blue color filter, blue-light source, because the color relation of light source is the color of required projection image, light source utilization factor height, the complete machine power consumption is very low, created condition for powered battery, made instrument be convenient to move; Image device can be the LCD assembly that comprises the driving circuit of decoding in the projector, also can be the DLP assembly that comprises the driving circuit of decoding; The position of decoding driving circuit in projector is as the criterion not block light path; It is dark that projector can project vein according to request for utilization, the erect image that other people soma is bright, and it is bright also can to project vein, the negative-appearing image that other people soma is dark; The venous projecting apparatus calibration several marks that can be discerned by infrared camera that the time only need on the back of the hand, draw, hand is placed under the venous projecting apparatus, shine with infrared light supply, mark on vein infrared image and the back of the hand is photographed by infrared camera and passes to projector, adjust infrared camera. the relative angle of ir reflector and position, size, angle and the position of projector projection image makes the mark that projects in the image can overlap fully with mark on the back of the hand, just can guarantee that the vein image that throwed overlaps with venous locations under the skin of dorsum of hand.
The invention has the beneficial effects as follows: make the vein image directly be apparent in skin surface, reduced the venipuncture difficulty.
The present invention is further described below in conjunction with drawings and Examples: the known parts such as power supply, circuit board, interface and other optical mirror slip that it should be noted that the projector's indispensability of not drawing among the figure, because these the understanding of the present invention explanations can't be played help, can make accompanying drawing seem in disorder on the contrary, instructions and Figure of description that the slip-stick artist of the industry can submit to according to the present patent application people are at an easy rate implemented.
Fig. 1 is the schematic diagram of structure of first embodiment of the present invention.
Fig. 2 is the schematic diagram of structure of second embodiment of the present invention.
1. infrared light supplies among the figure, 2. infrared camera, 3. projector, 4. ir reflector, 5. image device, 6. light source of projector, 7. projector lens.
In the embodiment shown in fig. 1, ir reflector in the venous projecting apparatus light path and infrared camera are installed between the camera lens and image device in the projector, the hand back vein infrared image is refracted to infrared camera later on by the ir reflector that projector lens is transmitted in the projector, and the turquoise image that image device demonstrates then passes ir reflector and projects on the back of the hand by projector lens.
In another embodiment shown in Figure 2, ir reflector in the venous projecting apparatus light path and infrared camera are installed in the projector lens below, infrared camera and projector install with an angle of 90 degrees, ir reflector is installed with miter angle between infrared camera and projector, the vein infrared image is projected the turquoise image for infrared camera, projector by the infrared external reflection mirror reflection then to pass ir reflector and project on the back of the hand on hand.
