Apparatus for conveniently fixing vein in non-invasive puncture

Abstract

The invention relates to apparatus for conveniently fixing the vein in non-invasive puncture. The apparatus comprises a shell, a display screen, a sensor chip, a near-infrared light processor, and bandages, wherein the shell is of a left-half-turning n-shaped structure, the shell comprises an upper shell and a lower shell, the display screen is arranged at the middle position of the upper surfaceof the upper shell, the near-infrared light processor is arranged at the middle position above the display screen, the sensor chip is arranged below the display screen, a power switch is arranged on one side of the sensor chip, the lower shell is provided with a puncture through hole, the bandages are fixedly arranged on two sides of the lower shell, and bandage surfaces on two sides are providedwith matching Velcro. The advantages of the apparatus are as follows: the apparatus uses bandage compression and is combined with the visual operation screen to perform venous puncture on a patient, and mainly uses the screen or the development on the skin to guide a doctor and nurse to confirm the position, depth and direction of the vein, and at the same time the bandages can help to fix a venous blood vessel at a puncture site, so that infusion only once is facilitated, and the repeated needle insertion is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for non-invasive puncture of fixed veins. Background technique [0002] At present, it is generally difficult for hospitals to inject and puncture intravenously without the help of auxiliary equipment, and it is generally realized by the work experience of medical staff. [0003] The projection infrared vascular imager that appears on the market is hand-held, usually equipped with two types of brackets, desktop and vertical, but additional vein fixation bandages (simple as rubber strips) are still required to fix the vein or finger local pressure during specific operations To puncture a vein. For some patients with thin and slippery blood vessels that are difficult to puncture clinically, venipuncture is still difficult, especially in the hands, arms and lower limbs, or it is necessary to puncture veins multiple times in the outpatient clinic due to medical need...

[0003] The projection infrared vascular imager that appears on the market is hand-held, usually equipped with two types of brackets, desktop and vertical, but additional vein fixation bandages (simple as rubber strips) are still required to fix the vein or finger local pressure during specific operations to puncture a vein

For some patients with thin and slippery blood vessels that are difficult to puncture clinically, venipuncture is still difficult, especially in the hands, arms and lower limbs, or it is necessary to puncture veins multiple times in the outpatient clinic due to medical needs (multiple blood draws on the same day) In laboratory tests + surgical anesthesia), it is even necessary to puncture the jugular vein for infusion and other treatments, so it is difficult to achieve "one-shot" in actual operation, so multiple inaccurate acupuncture often causes unnecessary harm to the patient, and also psychological pressure on the patient

[0004] Chinese patent application: CN209915954U discloses a simple blood vessel imaging device, including a fixed bump and a measuring body, the fixed bump is installed and fixed on the upper end of the measuring body, and the inner middle of the fixed bump is located on the measuring body. There is an irradiating bulb, and a light-transmitting protection block is arranged on the fixed bump above the irradiating bulb, and a brand logo block is arranged on the right side of the fixing bump on the measuring body, and a charging charging block is arranged in the middle of the left end of the measuring body. Jack, the inside of the charging jack is located on the measuring body and is provided with a charging protection ring, the middle of the right end of the measuring body is provided with an adjusting bolt, and the two sides of the adjusting bolt are located on the measuring body and are provided with side bumps, A finger gripper is arranged under the bottom of the measuring body, and side heat sinks are arranged in front of both sides of the measuring body. Although the device can observe veins in real time, the patient's hands are not fixed, resulting in The image projected to the original irradiation site is misaligned, so the patient cannot be punctured accurately, so it is not convenient to use

Although the device can effectively assist the patient in performing venipuncture, the fixation effect is not good. The fixing belt on the fixing plate cannot effectively fix the patient's arm, so it cannot accurately position and display the patient's puncture site, and the button used in the device Type battery, the power is limited, and it is inconvenient to replace

[0006] So to sum up, there is an urgent need for a device that is simple in structure, easy to operate, strong in practicability, can effectively assist venipuncture and facilitate non-invasive puncture of veins, and about this new device that is convenient for non-invasive puncture of veins, there is currently no No report
