Abstract

A vein imaging visualizer is capable of imaging red-light dark spots of subcutaneous veins on the hand back and bring convenience to medical staff to observe, position and puncture the subcutaneous veins and provide subsequent curing. The vein imaging visualizer comprises a base, a lower light source, a magnifying lens, a light shading soft curtain, an upper light source and a support, wherein the lower light source is an area light source formed by uniformly arranging red-light LEDs and white-light LEDs, and the upper light source is formed by uniformly arranging white-light LEDs on the lower side periphery of the magnifying lens, and light intensity of both the upper light source and the lower light source is adjustable, the height and the angle of the magnifying lens are adjustable, and the light-proof light shading soft curtain is mounted on the periphery of the magnifying lens. During use, a hand with the palm downwards is disposed on the lower light source which is turned on, and by the aid of the magnifying lens, magnified images of the red-light dark spots of the subcutaneous veins of the hand back can be clearly obtained, and puncture of the veins is facilitated.

Description

A kind of vein imaging scope

Affiliated technical field

This utility model relates to vein imaging scope under a kind of dorsal cutaneous, belongs to medical instruments field.

Background technology

Often utilize in clinical treatment and the check that the vein blood vessel paracentesis are drawn blood, infused, perfusion etc., its key problem in technology at first will manage to find the venae subcutaneae blood vessel, could play the pin puncture vessel to carry out follow-up treatment.At present the method for clinical employed location venae subcutaneae blood vessel mainly contains two kinds: 1. visual method: look to seek and localization of blood vessel with naked; 2. digital palpation for examination of trauma: seek and localization of blood vessel with the sensation of finger touch.But the object vein is slim and frahile when puncturing, during such as the child, because blood vessel is thin, fat deposit is thicker, is difficult for seeing clearly, wants to find fast and accurately the venae subcutaneae blood vessel just to seem very difficult.

The utility model content

For the deficiency of existing visual method or digital palpation for examination of trauma location venae subcutaneae blood vessel, this utility model provides a kind of technical scheme of vein imaging scope.

Described a kind of vein imaging scope is characterized in that being comprised of base, lower light source, magnifier, the soft curtain of shading, upper light source, support; Described lower light source is placed on the base, and evenly being arranged by dark red-light LED forms, and form upwards irradiation, luminous uniform lower light source, and light intensity can be regulated as required; Described dark red-light LED wavelength is 760nm ± 30nm; Described upper light source is comprised of white light LEDs, is embedded in the lower side periphery of described magnifier, can shine downwards, and light intensity can be regulated as required; Described magnifier height and angle can be regulated by adjusting knob as required, to obtain clearly vein imaging.The soft curtain of described shading is placed in the magnifier periphery, is made by lighttight soft fabric, in order to block the bias light in the surrounding.

The beneficial effects of the utility model are:

1. can form on skin of dorsum of hand surface directly visible, venae subcutaneae blood vessel HONGGUANG shadow image clearly of naked eyes, make things convenient for the medical worker to locate the venae subcutaneae blood vessel, for puncture, intravenous injection, perfusion etc. are offered help;

2.LED light source is cold light source, can not produce heating effect to skin, can skin ambustion, and safe and reliable;

3. be furnished with magnifier, can amplify the vein blood vessel image, can provide more clear, accurate observing effect for the medical worker, improve puncture speed and success rate.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

It is structure principle chart of the present utility model in the accompanying drawing.

Among the figure, 1. base 2. descends light source (dark red-light LED), 3. support, and 4. magnifier is 5. gone up light source (white light LEDs), and 6. the soft curtain of shading is 7. gone up light source light intensity regulating knob, and 8. the magnifier height adjustment knob is 9. descended the light source intensity adjusting knob.

The specific embodiment

Below in conjunction with Figure of description this utility model is described further:

As shown in Figure 1, described vein imaging scope is comprised of base 1, lower light source 2, lower light source intensity adjusting knob 9, support 3, magnifier 4, magnifier height adjustment knob 8, upper light source 5, upper light source light intensity regulating knob 7, the soft curtain 6 of shading.

Described lower light source 2 forms LED wavelength 760nm ± 30nm, 5～10 ° of the angles of divergence by 25～100 dark red smooth straw hat pipe LED; LED evenly arranges, and forms 9 square centimeters to 100 square centimeters uniform source of light, and the light intensity of light source and light-emitting area can be regulated by lower light source adjusting knob 9 as required.

Described upper light source 5 evenly is arranged in the lower edge of magnifier 4 by 10～60 white light LEDs, forms the ring-type light source.

Described magnifier 4 height can be regulated by magnifier adjusting knob 8, to obtain clearly Arterography venography.

During actual use this utility model, palm turned downwards for patient, hands is placed on the transparency glass plate, makes lower light source 2 can shine palm part, open lower light source 2, the light-emitting area of regulating lower light source 2 is no more than patient's hand size, can observe the hand back vein imaging by magnifier 4, according to the actual imaging effect, by the light intensity of the lower light source 2 of lower light source adjusting knob 9 adjustings, regulate the height of magnifieres 4 by magnifier adjusting knob 8, to obtain clearly vein blood vessel HONGGUANG shadow image under the dorsal cutaneous; Can open in case of necessity light source 5 and illuminate the back of the hand and on every side, if bias light has influence on observing effect in the surrounding, the soft curtain 6 of shading that can put down magnifier 4 peripheries blocks bias light.

Claims

1. vein imaging scope, formed by base, lower light source, magnifier, the soft curtain of shading, upper light source, support, it is characterized in that: a upwards lower light source of irradiation is housed on the base, side periphery is equipped with the upper light source of downward irradiation under the magnifier, and the magnifier periphery is equipped with the soft curtain of lighttight shading.
