Abstract
A venipuncture display instrument is characterized in that a retaining cap, a branch pipe, a display screen, a camera, a luminescent tube and an optical filter are included; one end of the branch pipe is connected with the retaining cap, and the other end of the branch pipe is connected with the display screen; the camera and the luminescent tube are mounted on the display screen; the camera is composed of a lens and a CCD (charge coupled device); and the optical filter is mounted between the lens and the CCD. Through the technical scheme of the utility model, the distribution and trend of superficial blood vessels which are deeper and can not be seen and touched in normal times can be seen clearly, and then the light source, the video camera and the display are integrated to be all-in-one and designed into a head-wearing type; and the venipuncture display instrument has a simple structure and low cost.
Description
Technical field
This utility model relates to medical instruments field, specifically refers to the venipuncture display instrument that a kind of venipuncture is used.
Background technology
Since the human own intravenous injection, just found to have the superficial vein of a lot of infant and indivedual adult patients not difficult to find; Especially infant is difficult to accomplish the disposable venipuncture success, therefore, how to make the medical worker can see clearly that patient's shallow-layer vein just becomes a clinical difficult problem in diagnosis and treatment process.Successful development was arranged in this respect, but the equipment principle complexity involves great expense abroad, be not suitable for the limited place of economic strengths such as outpatient service or local medical institutions and use.
Summary of the invention
This utility model provides a kind of venipuncture display instrument, can solve because patient's shallow-layer vein is unintelligible, thus the difficult problem that can't implement to puncture.
For achieving the above object, this utility model is by the following technical solutions:
A kind of venipuncture display instrument is characterized in that: described vein mirror comprises headgear, arm, display screen, photographic head, luminous tube and optical filter, and wherein arm one end connects headgear, and the other end connects display screen; Photographic head and luminous tube are installed on the display screen; Photographic head is made up of camera lens and CCD, between camera lens and CCD optical filter is installed.
Described optical filter is the optical filter that can only see through infrared light.
By technical scheme described in the utility model can see clearly naked eyes can't see at ordinary times hands also touch less than the distribution and the trend of more deep shallow-layer blood vessel.Again light source, video camera and display are arranged to all-in-one, and are designed to wear-type, simple in structure, with low cost.
Description of drawings:
Fig. 1 is a venipuncture display instrument structural representation described in the utility model;
Fig. 2 is headgear and arm connection diagram;
Description of reference numerals:
1. headgear, 2. arm, 3. display screen, 4.CCD, 5. camera lens, 6. luminous tube, 7. optical filter.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is elaborated.
Fig. 1 is a venipuncture display instrument structural representation described in the utility model, and Fig. 2 is headgear and arm connection diagram, and as shown in the figure, arm 2 one ends connect headgear 1, and the other end connects display screen 3, passes electric wire in arm 2 inside; Photographic head and luminous tube 6 are installed on the display screen 3; Photographic head is made up of camera lens 5 and CCD4, and optical filter 7 is installed between camera lens 5 and CCD4, and this optical filter 7 is the optical filter that can only see through infrared light.
The venipuncture display instrument is developed the distinct principle of infrared reflection of light according to human body shallow-layer blood vessel and soft tissue.Long-wave infrared (wavelength is more than 1.5 microns) is during to human exposure, and the overwhelming majority is reflected and is that the shallow layer skin skin tissue absorbs, and the degree of depth of transdermal only reaches 0.05～2 millimeter; Short infrared (wavelength 0.73-1.5 micron) penetrates to be organized the deeplyest, and penetration depth can reach 10 millimeters.The characteristics that hemoglobin has obvious selectivity to absorb to infrared light, therefore, the infrared light that reflects from human body is diverse; The shallow-layer blood vessel in image gray value apparently higher than soft tissue.
With the infrared light supply of a specific band, impinge upon on the relevant position of human body, the DV of a special use of reuse is transformed into the signal of telecommunication with the optical signal that reflects and is transported on the video display units.At this moment we just can see clearly naked eyes can't see at ordinary times hands also touch less than the distribution and the trend of more deep shallow-layer blood vessel.Again light source, video camera and display are arranged to all-in-one, and are designed to wear-type.The medical worker puts on it, just can finish venipuncture with hundred-percent success rate under its guiding.
