Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a light-proof protective cover for a syringe. Background Technology

[0002] Syringes, a common medical device in clinical settings, are widely manufactured from transparent, high-quality materials such as polypropylene and designed for single use to ensure aseptic technique and patient safety. Their core function encompasses the ability to inject and aspirate liquids or gases, making them an indispensable tool in healthcare procedures. During use, nurses can clearly observe the position of the black plunger through the graduations on the transparent syringe casing, allowing for precise measurement and control of the remaining amount of medication or gas, achieving accurate drug delivery. In clinical practice, the use of certain medications requires extremely stringent light protection, necessitating the use of syringes with light-protective properties to ensure the stability and efficacy of the medication during injection.

[0003] There are many existing technologies for light-shielding injectors, such as:

[0004] Chinese Patent Publication No. CN214807451U discloses a light-shielding syringe, comprising an injection tube, with baffles fixedly connected to both sides of the upper end face of the injection tube, a connecting seat fixedly connected to the lower end face of the injection tube, and a light-shielding sleeve fixedly connected to the outer wall of the injection tube. The lower end faces of the two baffles are each formed with a groove, and light-shielding protrusions are fixedly connected to the interior of the two grooves. The light-shielding protrusions are fixedly connected to the light-shielding sleeve. A scale is provided on the outer wall of the injection tube, and a through groove matching the scale is opened on the outer wall of the light-shielding sleeve. A light-shielding seat is installed on the outer wall of the connecting seat.

[0005] Therefore, most light-shielding syringes have a light-shielding sleeve on the outer periphery of the injection tube. The light-shielding sleeve is matched and fixed to the scale on the injection tube through a through groove. However, in practical applications, due to the limited size of the protrusion or concavity of the scale on the injection tube, the light-shielding sleeve is often difficult to be stably fixed by the scale and is prone to falling off.

[0006] In view of this, we propose a light-proof protective cover for syringes. Utility Model Content

[0007] The purpose of this invention is to provide a light-proof protective cover for syringes to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A syringe light-shielding protective sleeve includes a syringe barrel, a piston rod slidably connected to the syringe barrel, and a light-shielding outer sleeve installed on the outer wall of the syringe barrel. The outer surface of the light-shielding outer sleeve is provided with scale lines that are the same size as the syringe barrel. One end of the light-shielding outer sleeve is equipped with an elastic ring, and the outer wall of the elastic ring is symmetrically provided with fixing ears. The inner wall of the elastic ring is provided with anti-slip particles.

[0010] As a further embodiment of this utility model: the light-proof jacket includes a base layer, an ultraviolet-proof layer and a wear-resistant layer arranged sequentially from the inside to the outside.

[0011] As a further embodiment of this utility model: the base layer is made of polycarbonate material with good light transmittance, the UV protection layer is made of UV isolation film, and the end of the light-proof jacket away from the elastic band has a conical structure.

[0012] As a further embodiment of this utility model: a flexible light-shielding sheet is installed at the conical end of the light-shielding jacket, a label is installed on one side of the light-shielding sheet, and a tear-off ear and a Velcro tassel are installed on the other side in sequence. An observation port is provided at the junction of the outer wall of the light-shielding jacket and the tear-off ear, and a Velcro tassel is provided on the outer side of the observation port.

[0013] As a further embodiment of this utility model: the syringe barrel also includes symmetrically arranged hand-held side plates, and a pressing plate is installed at the end of the piston rod away from the syringe barrel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This syringe light-proof protective sleeve features an elastic band at one end of the light-proof outer sleeve, with anti-slip particles on the inner wall of the elastic band. When the light-proof outer sleeve is placed on the outer surface of the syringe barrel, the elasticity of the elastic band and the anti-slip particles ensure a tight and secure fit between the outer sleeve and the barrel, preventing the outer sleeve from accidentally falling off. This enhances safety and convenience, allowing users to easily and quickly put on and take off the outer sleeve, thus optimizing the user experience.

[0016] 2. The syringe's light-shielding protective cover can be easily opened by grasping the tear tab, separating the hook and loop side of the Velcro from the rough side, thus exposing the observation port on the light-shielding cover. This allows for convenient opening of the light-shielding cover during use to observe the properties of the drug in the syringe during infusion, preventing drug precipitation. In addition, the label attached to the light-shielding cover can be conveniently used to record drug information or patient information. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Most light-shielding syringes currently have a light-shielding sleeve on the outer periphery of the injection tube. The light-shielding sleeve is matched and fixed to the scale on the injection tube through a through groove. However, in practical applications, due to the limited size of the protrusion or indentation of the scale on the injection tube, the light-shielding sleeve is often difficult to be stably fixed by the scale and is prone to falling off.

[0027] Therefore, please refer to Figures 1-3As shown, the purpose of this embodiment is to provide a syringe light-shielding protective sleeve, which includes a syringe barrel 1, a piston rod 6 slidably connected to the syringe barrel 1, and a light-shielding outer sleeve 2 installed on the outer wall of the syringe barrel 1. Handheld side plates 5 are symmetrically arranged on both sides of the insertion end of the piston rod 6 of the syringe barrel 1, and a pressing plate 7 is installed at the end of the piston rod 6 away from the syringe barrel 1. Considering that the light-shielding outer sleeve 2 needs to be positioned when it is fitted onto the outer surface of the syringe barrel 1 to prevent it from not being properly fitted, the outer surface of the light-shielding outer sleeve 2 is provided with scale lines 3 that are the same size as the syringe barrel 1, which are used for auxiliary positioning. To facilitate the installation of the light-shielding outer sleeve 2, and... When in use after installation, the light-shielding cover 2 will not fall off. Therefore, an elastic ring 4 is installed at one end of the light-shielding cover 2, and the outer wall of the elastic ring 4 is symmetrically provided with fixing ears 14. The inner wall of the elastic ring 4 is provided with anti-slip particles 15. The elasticity of the elastic ring 4 and the anti-slip particles 15 can ensure a tight and stable fit between the light-shielding cover 2 and the syringe body, thereby preventing the cover from falling off accidentally, enhancing safety, improving convenience, and allowing users to easily and quickly put on and take off the cover, thus optimizing the user experience. Considering the shape of the syringe body 1, the end of the light-shielding cover 2 away from the elastic ring 4 is a conical structure. The conical design makes the light-shielding cover 2 fit the syringe body 1 more closely.

[0028] Please see Figure 4 As shown, given that the light-protected medication primarily needs protection against ultraviolet (UV) radiation rather than all types of light, the light-protected jacket 2 is designed with a layered structure, consisting of the following layers from the inside out: a base layer 21, providing necessary fit and protection; a UV-protective layer 22, specifically designed to effectively block UV radiation; and a wear-resistant layer 23, enhancing the jacket's durability and abrasion resistance. The base layer 21 is made of highly transparent polycarbonate, the UV-protective layer 22 uses a UV-blocking film, and the wear-resistant layer 23 is also made of transparent material, allowing for easy observation of the piston rod 6's position through the light-protected jacket 2, thus ensuring the stability and effectiveness of the medication. It is important to note that the inner diameter of the light-protected jacket 2 and the inner diameter of the elastic band 4 are consistent with the outer diameter of the syringe barrel 1, ensuring that the light-protected jacket 2 and the elastic band 4 can fit tightly onto the syringe barrel 1. The elastic band 4 and the two fixing ears 14 are integrated into a single structure to enhance the connection strength between the elastic band 4 and the fixing ears 14.

[0029] Please see Figure 3As shown, considering the possibility of drug deterioration, precipitation, or flocculent matter inside the syringe barrel 1, especially in cases of deterioration, it is necessary to directly observe the internal condition of the syringe barrel 1, rather than observing it through the light-shielding jacket 2. This is because the UV-protective layer 22 may contain specific chemicals or additives to enhance its UV protection effect. These components may affect the light transmitted through it, and the results observed by the human eye may be inaccurate. Therefore, a flexible light-shielding sheet 8 is installed at the conical end of the light-shielding jacket 2. A label 9 is installed on one side of the light-shielding sheet 8, which allows for convenient recording of drug or patient information, further improving ease of use and information traceability. On the other side of the light-shielding sheet 8, a tear-off tab 11 and a Velcro rivet 1 are sequentially installed. 0. An observation port 12 is provided at the junction of the outer wall of the light-proof cover 2 and the tear tab 11. The outer side of the observation port 12 is provided with a Velcro surface 13. In use, the light-proof sheet 8 can be easily opened by holding the tear tab 11. At this time, the Velcro barbed surface 10 on the light-proof sheet 8 will separate from the Velcro surface 13 on the light-proof cover 2, thereby exposing the specially opened observation port 12 on the light-proof cover 2. The properties of the drug in the syringe barrel 1 during drug infusion can be easily observed through the observation port 12 of the light-proof cover 2. After the observation is completed, the light-proof sheet 8 can be covered over the observation port 12 again, and the Velcro barbed surface 10 and the Velcro surface 13 can be glued together to easily block the observation port 12, continue to protect the drug from light, and ensure that the light-proof function of the light-proof cover 2 is fully utilized.

[0030] In summary, the working principle of this solution is as follows:

[0031] This design is primarily applied in medical environments where drug infusion requires light protection. In medical practice, many drugs, such as sodium nitroprusside, esomeprazole, and omeprazole, undergo oxidation and degradation reactions when exposed to light during infusion. This not only reduces drug potency but may also cause changes in color and precipitation, severely affecting drug quality and potentially increasing toxicity. Therefore, strict light protection measures must be taken when infusing these drugs to ensure their safety and efficacy. This design utilizes a light-protecting jacket 2, which tightly fits over the outer surface of the syringe barrel 1, providing effective light protection. The material of the light-shielding jacket 2 effectively blocks light, especially ultraviolet rays, thus significantly reducing the risk of drug exposure to light during infusion. This avoids the cumbersome and inconvenient nature of traditional light-shielding methods (such as using light-shielding bags made of black cloth, paper, or plastic), and also solves the problem of the generally high price of light-shielding syringes, further reducing the cost of use. In addition, the light-shielding jacket 2 is also designed with an observation port 12 and a light-shielding sheet 8, which allows medical staff to clearly observe the properties of the drug in the syringe barrel 1 during infusion without removing the light-shielding jacket 2, thereby ensuring the safety and accuracy of the infusion process.
