[0001] This application relates to the field of medical device technology, and in particular to a light-proof cover for an intravenous syringe. Background Technology

[0002] An intravenous syringe is a medical device used to draw or inject fluids. It is used when administering intravenous injections to patients. Some intravenously administered medications are photosensitive and undergo oxidation upon exposure to light, which can reduce their efficacy or even produce harmful substances. Therefore, light must be avoided during intravenous injections.

[0003] In related technologies, the light-protected intravenous syringes currently used in hospitals are relatively expensive and cannot be reused, resulting in high usage costs. While ordinary intravenous syringes are cheaper, they do not provide light protection and are not suitable for injecting drugs that require light protection. Therefore, we propose a light-protected sleeve for intravenous syringes to solve the above problems. Utility Model Content

[0004] The purpose of this application is to provide a light-shielding sleeve for intravenous needles, which facilitates the installation and fixation of the sleeve onto the intravenous needle, ensuring a secure and stable fit that is not easily loosened or detached. This effectively protects the intravenous needle from light and allows for easy removal of the sleeve from the needle. The operation is simple and convenient, enabling repeated use of the sleeve and saving costs and resources.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a light-shielding sleeve for intravenous needles, comprising a light-shielding sleeve body that can be detachably fitted onto an intravenous needle, wherein the intravenous needle includes an infusion tubing, an inlet head, and a needle head, the inlet head and the needle head being fixedly connected to the two ends of the infusion tubing, the light-shielding sleeve body comprising a light-shielding sleeve body and two connecting positioning parts, the two connecting positioning parts being respectively disposed at the two ends of the light-shielding sleeve body, the infusion tubing being located within the light-shielding sleeve body, and the inlet head and the needle head extending into the light-shielding sleeve body at their respective close ends.

[0023] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a light-shielding sleeve for an intravenous catheter, including a light-shielding sleeve body 2 that can be detachably fitted onto an intravenous catheter 1. The intravenous catheter 1 includes an infusion tubing 11, an inlet head 12, and a needle head 13. The inlet head 12 and the needle head 13 are respectively fixedly connected to both ends of the infusion tubing 11, wherein:

[0025] The light-shielding sleeve body 2 includes a light-shielding sleeve body 21 and two connecting and positioning parts 22. The two connecting and positioning parts 22 are respectively located at both ends of the light-shielding sleeve body 21. The infusion tubing 11 is located inside the light-shielding sleeve body 21. The infusion head 12 and the needle head 13 extend into the light-shielding sleeve body 21 at their respective close ends. By using the two connecting and positioning parts 22 to respectively fit and fix the light-shielding sleeve body 2 onto the intravenous needle 1, it can be used to effectively block light and prevent adverse effects on drugs that need to be protected from light during infusion.

[0026] In this embodiment, the connecting positioning part 22 includes an elastic connecting ring 221, a double-sided hook and loop fastener 223, and an elastic anti-slip ring 224. The elastic connecting ring 221 is fixedly connected to one end of the light-shielding sleeve 21. An annular groove 222 is provided on the outer ring wall of the elastic connecting ring 221. One end of the double-sided hook and loop fastener 223 is fixedly connected in the annular groove 222. The annular groove 222 is used to provide space for the double-sided hook and loop fastener 223 to wrap and stick. The double-sided hook and loop fastener 223 includes a braided tape layer, a napped layer, and a hooked layer. The napped layer and the hooked layer are fixedly connected to the two side surfaces of the braided tape layer, respectively. The elastic anti-slip ring 224 is fixedly connected to the inner ring wall of the elastic connecting ring 221. Anti-slip texture is provided on the inner ring wall of the elastic anti-slip ring 224. The friction generated when the two elastic anti-slip rings 224 contact the liquid inlet head 12 and the needle head 13 respectively can improve the stability and reliability of the light-shielding sleeve body 2 being fixed on the intravenous needle 1.

[0027] In this embodiment, the elastic connecting ring 221 and the light-shielding sleeve 21 are integrally manufactured to improve the stability and reliability of the connection between the elastic connecting ring 221 and the light-shielding sleeve 21.

[0028] In this embodiment, the elastic anti-slip sleeve 224 and the elastic connecting sleeve 221 are integrally manufactured to improve the stability and reliability of the connection between the elastic anti-slip sleeve 224 and the elastic connecting sleeve 221.

[0029] In this embodiment, the maximum diameter of the liquid inlet head 12 is smaller than the inner diameter of the elastic connecting ring 221, which ensures that the liquid inlet head 12 can smoothly pass through the elastic connecting ring 221 and the elastic anti-slip ring 224.

[0030] In this embodiment, the light-shielding sleeve 21, the elastic connecting ring sleeve 221, and the elastic anti-slip ring sleeve 224 are all made of black silicone or black polylactic acid. By using black silicone or black polylactic acid to make the light-shielding sleeve 21, the elastic connecting ring sleeve 221, and the elastic anti-slip ring sleeve 224, they not only have the functions of being soft, elastic, and light-shielding, but also have the advantages of being non-toxic, environmentally friendly, having good temperature resistance, and being corrosion resistant. They can be reused, saving resources.

[0031] With the above structure, the intravenous syringe light-proof sleeve provided in this application, when in use:

[0032] When the light-shielding sleeve body 2 is installed and fixed on the intravenous needle 1, first, the inlet head 12 of the intravenous needle 1 is inserted through the bottom elastic anti-slip ring 224, the light-shielding sleeve body 21 and the top elastic anti-slip ring 224 in sequence, so that the infusion tubing 11 is completely located inside the light-shielding sleeve body 21, and the bottom end of the inlet head 12 is inserted through the top elastic connecting ring 221, and the top end of the needle head 13 is inserted through the bottom elastic connecting ring 221. Then, the two double-sided Velcro 223s are tightly wrapped and pasted into the corresponding annular grooves 222, so that the two elastic connecting rings 221 are deformed and tightened. At this time, the two elastic anti-slip rings 224 are respectively attached to the inlet head 12 and the needle head 13, thus completing the secure installation and fixation of the light-shielding sleeve body 2 on the intravenous needle 1. It is not easy to loosen or fall off during use, thus achieving effective light protection for the intravenous needle 1.

[0033] When removing the light-shielding sleeve body 2 from the intravenous needle 1 for operation, the two double-sided Velcro straps 223 are unfastened in sequence. At this time, under the elastic force of the two elastic anti-slip rings 224 and their own elasticity, the clamping and fixing of the liquid inlet head 12 and the needle head 13 are released, and the light-shielding sleeve body 2 can be easily removed from the intravenous needle 1, so as to facilitate the repeated use of the light-shielding sleeve body 2, saving costs and resources.
