A temporary absorbable venous occlusive stent for use in a varicose vein treatment method includes a stent body, a bio-absorbable material associated with the body, and a closure for blocking blood flow past the stent when implanted in a vein. The stent produces localized blood clotting, fibrosis and vein collapse as it is absorbed. A permanent blockage is produced that prevents the undesirable back flow of blood from above the blockage site, thereby reducing distension of a varicose vein below the blockage site.

The transillumination device has an orange light, in the range of 580-620 nm. Orange light has been found to be beneficial for superficial veins. Red light is used for deeper veins and darker skin. The transillumination device may have a single light source able to change colors. Two different light sources, each having a different color or different transillumination devices, each having a different color, may be used for diagnostic purposes.

The disclosed method for seeking body veins utilizes a skin-clinging irradiation mode, wherein red light with 600-650nm of wave length is radiated to penetrate the fat tissue, which develops optical transmission, refraction and diffusion, as a result, the lateral diffusion illuminating effect can be produced, thus appreciable shadow can be formed by the blood vessels at the diffused illumination of the red light, thus the problem of difficult blood vessel positioning for patients having thick fat layer can be solved.

The present invention relates to a superficial vein puncture auxiliary system guided by infrared and ultrasonic positioning, characterized in that the puncture system includes an infrared guiding unit and an ultrasonic positioning unit, and the infrared guiding unit includes an infrared light source, a signal acquisition unit, and an infrared image processing unit , an image projection unit, an infrared image display unit, the ultrasonic positioning unit includes a high-frequency ultrasonic probe, an ultrasonic image processing unit, an ultrasonic image display unit, and a puncture needle connecting frame fixed on the ultrasonic probe. The system can not only locate and display superficial veins through infrared imaging, but also identify the depth of veins through the ultrasonic unit under the guidance of infrared images, so as to realize real-time observation of needle insertion angle and depth of puncture needles, reducing the risk of venipuncture. Difficulty, improve puncture accuracy.

An illumination device that has an orange light, with LEDs having a wavelength in the range of 580-620 nm, and / or a red light with LEDs having a wavelength of light in the range of 620-650 nm for side-transillumination of the veins. Orange light has been found to be beneficial for transillumination of superficial veins, while red light has been found to be beneficial for transillumination of deeper veins. In addition, the device has white light which is used for illumination of the surface of the skin. The illumination device contains a manual or automatic switch or switching mechanism that allows the user to easily switch between the orange light / red light and the white exam light by simply pressing a button or moving the device.

A disposable penile erection device that has a positive locking mechanism on the superficial veins around the base of a human penile organ. The device is a tubular structure adapted to the penis to be secured in loop configuration about the base of the penis to provide two (2) adjustable and lockable radial constriction force about the base of the penis. Methods for using the device are also provided.

The invention discloses a new method for treating varicose veins of the lower extremities and the resulting expansion, elongation and bending of the superficial veins of the lower extremities, straightening the blood column of the vein wall of the lower extremities, and increasing its height, bulge, and acidity of the affected limbs. swelling, fatigue, edema, brown pigmentation, ulcers and thrombophlebitis embolism. It is made of holly, trigonum, chuanxiong, motherwort, danshen, hawthorn slices, angelica, white peony root, milletus, achyranthes bidentata, kudzu root, astragalus, scrophulariaceae, and licorice, and is made into powder or powder according to the conventional preparation methods of the pharmacopoeia. The granule is a good agent with definite curative effect and quick effect of the present invention.

The invention relates to a device for intravenous injection of a mouse tail and superficial intravenous injection of other parts. The device comprises a base, a transparent tube, a front fixing part and a rear fixing part, wherein a notch is formed in the rear fixing part, and ventilation holes are formed in two side edges of the transparent tube; the base is a closed cavity with a light source inside, the base comprises a top plate, a soleplate and four side plates, an adjustable light-transmitting operation panel which is hinged to the top plate is arranged between the side plate facing one end of the tail part of a mouse and the top plate, the side edge of the top plate is provided with a fixing plate facing the interior of the base, the adjustable light-transmitting operation panel is provided with an angle adjusting screw for adjusting an angle between the adjustable light-transmitting operation panel and the fixing plate, and other three side edges of the adjustable light-transmitting operation panel are respectively provided with an elastic light screening plate which is connected to the side edge of the adjacent base. By adopting the device, the safety of the operator is adequately guaranteed, and the operator can be prevented from being bitten by the mouse when in injection; moreover, the mouse is firmly fixed, the stress response of the mouse can be prevented from affecting the experiment result, and the experiment result is more reliable.
