Problems solved by technology

[0002] Infusion is a basic medical method; during the infusion process, due to the inconspicuous blood vessels in the hands of some patients, it is difficult for medical staff to accurately insert the needle into the blood vessel. After a period of time, the hand will have adverse reactions such as swelling, which will also greatly affect the treatment effect.

Embodiment 1

[0013] exist figure 1 In the first shown embodiment, the improved infusion device includes an infusion tube 1 and an infusion needle 2, and an infusion dropper 3 is connected in series in the infusion tube 1; an illuminating lamp 4 is provided on the upper part of the infusion dropper 3, The illuminating lamp 4 can downwardly generate light that is injected into the lower liquid outlet of the infusion dropper 3 .

[0014] In the first embodiment, the illuminating lamp 4 is oblate and is arranged on the outer upper end of the infusion dropper 3 , and the infusion tube 1 passes through the central opening of the illuminating lamp 4 . The illuminating lamp 4 is a spotlight, which can be composed of a ring lamp tube surrounding the infusion tube 1 and a convex lens at its lower part to produce a light cone coaxial with the infusion drop tube 3, and the apex of the light cone falls on the outlet of the infusion drop tube 3. In the liquid mouth.

[0015] In addition, the illuminat...

Embodiment 2

[0018] for figure 2 The second embodiment shown is different from the first embodiment in that the infusion tube located between the infusion dropper 3 and the infusion needle 2 has a prompting layer 5 made of optical diffusion material on the outer surface. Thus, when the infusion tube 1 is filled with liquid medicine, due to the total reflection effect, the light is completely confined in the infusion tube 1, and the prompting layer 5 does not emit light at this time, and when the liquid medicine is infused, only When the air remains, the total reflection effect disappears, and the light will pass through the infusion tube 1 and irradiate to the prompting layer 5, so that the section of the infusion tube from the infusion dropper 3 to the infusion needle 2 will emit light, thereby forming a striking reminder when the liquid medicine is infused.

Abstract

The invention provides an improved infusion device. The improved infusion device comprises an infusion tube and an infusion needle, wherein an infusion dropper is connected to the interior of the infusion tube in series; an illuminating lamp is arranged on the upper portion of the infusion dropper and can downwards generate light emitted into a lower liquid outlet of the infusion dropper; the illuminating lamp is arranged at the upper end of the outer portion of the infusion dropper and is a spotlight; a light cone coaxial with the infusion dropper is generated; and the vertex of the light cone falls into the liquid outlet of the infusion dropper. The improved infusion device can assist a medical staff in accurately pricking a needle into the blood vessel.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an infusion device. Background technique [0002] Infusion is a basic medical method; during the infusion process, due to the inconspicuous blood vessels in the hands of some patients, it is difficult for medical staff to accurately insert the needle into the blood vessel. After a period of time, the hand will produce adverse reactions such as swelling, which also greatly affects the therapeutic effect. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide an improved infusion device, which can assist medical staff to accurately insert the needle into the blood vessel. [0004] The technical solution adopted by the present invention to solve the technical problem is: the improved infusion device includes an infusion tube and an infusion needle, the infusion tube is connected in series with an infusion dropper; the up...
