Description

Technical Field

[0001] This utility model relates to the field of injection equipment technology, specifically to a light shield for a syringe. Background Technology

[0002] When administering medication via an infusion pump, a syringe is always used in conjunction. As a common medical device, syringes are used to protect certain medications (such as certain chemotherapy drugs and vitamins) from light. These medications are photosensitive and require light protection during injection to prevent decomposition or degradation due to light exposure, which could affect efficacy or cause adverse reactions. Traditionally, light shields are used for this purpose. However, existing syringe light shields are usually fixed structures, which present the following technical problems: 1. Insufficient adaptability: The length and inner diameter of existing light shields are usually fixed, making it difficult to adapt to syringes of different specifications (such as different capacities, lengths, and diameters), thus limiting their application range.

[0003] 2. Limited fixing methods: Most sunshades are fixed by simple pasting or binding, which is inconvenient to fix according to specific usage.

[0004] 3. Poor ease of operation: Some light shields are not designed with compatible parts for the syringe needle hub structure, resulting in exposed needle hubs or inconvenient installation, and lack of reliable clamping of the syringe, which may cause relative sliding between the light shield and the syringe. Utility Model Content

[0005] The purpose of this invention is to provide a light shield for syringes, which solves the problem mentioned in the background art that existing light shields cannot flexibly adapt to syringes of different specifications.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a light shield for a syringe, comprising a light shield body and a fixing component disposed on the light shield body, wherein the light shield body comprises a first cover and a second cover slidably disposed on the first cover, and both the first cover and the second cover are provided with a pressing component, both the first cover and the second cover are semi-cylindrical hollow structures and one end of the second cover is provided with a stop block.

[0007] Furthermore, the clamping assembly includes a slide rod and a pressing plate that slides with the slide rod; a spring is sleeved on the slide rod, and the two ends of the spring are respectively connected to the pressing plate and the slide rod.

[0008] Furthermore, the stop block is provided with an opening.

[0009] Furthermore, the fixing component includes adhesive plates respectively disposed on both sides of the first cover and the second cover.

[0010] Furthermore, the fixing component includes elastic bands respectively disposed on both sides of the first cover and the second cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Through the sliding engagement of the first cover and the second cover, the overall length of the light shield can be flexibly adjusted according to the length of the syringe to accommodate syringes of different lengths; the clamping assembly can adaptively adjust the clamping force of the pressure plate on the syringe through the spring force to adapt to syringe barrels of different diameters, ensuring a tight fit and avoiding insecure fixation or drug exposure due to diameter differences.

[0012] 2. It offers two fixing methods: adhesive plate or elastic band. The appropriate fixing method can be selected according to the structure of the injection pump or other equipment. It is suitable for adhesive fixing on flat surfaces as well as binding fixing of cylindrical parts, improving the flexibility of use and the stability of fixing.

[0013] 3. The stop block at the end of the second cover is made of silicone rubber and has an opening, which can accurately engage the needle hub of the syringe, thus achieving both light protection for the needle hub and facilitating quick positioning and installation; the semi-cylindrical hollow structure, combined with the light-shielding material, provides comprehensive light protection while ensuring normal installation and operation of the syringe, preventing the drug from deteriorating due to light exposure.

[0014] In summary, this invention effectively solves the problems of poor adaptability, unstable fixation, and inconvenient operation of traditional light shields through adjustable length, self-adaptive clamping, diversified fixation, and targeted structural design, significantly improving the convenience and reliability of clinical use.

[0017] Please see Figure 1A light shield for a syringe is disclosed, comprising a first shield 1 and a second shield 2. Both the first shield 1 and the second shield 2 are made of amber-colored plastic or a transparent polymer material with added light-blocking agent. Both shield 1 and shield 2 are semi-cylindrical hollow structures, with a stop block 3 at one end of the second shield 2. A sliding groove is formed on the first shield 1, and the second shield 2 slides into the groove. A protrusion is provided at the other end of the second shield 2 to prevent it from slipping off the first shield 1. By allowing the second shield 2 to slide on the first shield 1, the length of the light shield can be changed to accommodate syringes of different lengths. A clamping component is provided on the first shield 1 and the second shield 2 to clamp the syringe, accommodating syringes of different diameters. The stop block 3 is made of silicone rubber and has an opening for placing the syringe needle hub.

[0018] Specifically, the clamping assembly consists of a slide rod 4 and a pressing plate 5. The slide rod 4 and pressing plate 5 are made of materials such as PP and PE. An arc-shaped pressure port is formed on one side of the pressing plate 5, and the other side of the pressing plate 5 extends outward to form a sliding cylinder. The slide rod 4 is located inside the sliding cylinder and can slide within it. A spring 6 is fitted onto the slide rod 4, and both ends of the spring 6 are respectively engaged with one end of the sliding cylinder and one end of the slide rod 4. The spring 6 should be a spring with a low elastic coefficient, generating less elastic force, in order to fix the light shield and prevent the pressing plate 5 from damaging the syringe. To increase the stability of the pressing plate 5, two or more slide rods 4 can be provided on the first cover 1 and the second cover 2 respectively.

[0019] Example 1 Please see Figure 2 The fixing components are adhesive plates 7 respectively located on both sides of the first cover 1 and the second cover 2. The light shield is attached to the infusion pump using medical paper tape, double-sided tape, etc.

[0020] Example 2 Please see Figure 3 The fixing components can also be elastic bands 8 respectively provided on both sides of the first cover 1 and the second cover 2, which are used to tie the light shield to the injection pump, or to fix it by setting buckles or Velcro at the ends of the elastic bands 8.

[0021] Working process and principle of this utility model: When using this light shield, first place the syringe in the syringe slot of the injection pump and secure it using the pump's pressure plate. Then, the operator slides the second shield 2 to fit the length of the syringe. Next, place the stop 3 on the second shield 2 at the end of the syringe barrel and position the needle seat in the opening on the stop 3. Simultaneously, the pressing plate 5 presses against the syringe barrel, causing the spring 6 to retract. Finally, secure the light shield to the injection pump using the fixing assembly.
