Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical clinical trial technology, specifically to a protective device for temporary drug storage. Background Technology

[0002] In drug clinical trials, some pharmaceutical companies, during the development of new dosage forms, such as patches or gels for external use, have developed gels of the same drugs that can be directly applied to the affected area for better absorption and ease of use. This necessitates pharmacokinetic and bioequivalence studies compared to existing dosage forms. To ensure accurate dosage and reduce water evaporation during administration, syringes are used to draw the drug directly from the tubing. However, the needle must be removed during drawing and cannot be reinserted afterward, as the needle position can easily cause drug residue and contamination. Furthermore, using the drug with the needle attached poses a risk of accidental injury to researchers. To address this issue, this invention provides a simple, well-sealed, and reusable protective device for temporary drug storage. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a protective device for temporary storage of drugs with a simple structure and good sealing performance, which is used to cover the tip of a syringe to seal and preserve the drugs temporarily stored in the syringe.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] A protective device for temporary storage of drugs includes a cylindrical or conical transparent protective sleeve with one end open and an even number of annular locking heads evenly fixed at the opening. The locking heads are made of flexible material, and gaps are left between adjacent locking heads. The multiple locking heads form a locking ring to clamp the syringe, and the inner diameter of the locking ring is smaller than the outer diameter of the syringe. Half of the sequentially adjacent locking heads are connected to an opening and closing handle, and the other half of the sequentially adjacent locking heads are connected to another opening and closing handle. An annular sealing ring is fixed on the inner wall of the protective sleeve, and the inner diameter of the sealing ring is smaller than the tip diameter of the syringe.

[0006] In one embodiment of this utility model, an annular sealing sleeve is fixed on the side of the sealing ring near the opening of the protective sleeve, and the inner diameter of the sealing sleeve is adapted to the outer diameter of the tip of the syringe.

[0007] As one embodiment of this utility model, a plurality of sealing rings with different inner diameters are arranged along the axial direction on the inner wall of the protective sleeve. The inner diameter of the plurality of sealing rings gradually decreases from the opening end of the protective sleeve to the other end. The sealing rings with different inner diameters are used to seal the syringe tip ends with different outer diameters.

[0008] In one embodiment of this utility model, each of the sealing rings is fixed with an annular sealing sleeve on the side near the opening of the protective sleeve. The inner diameter of the sealing sleeve gradually decreases from the opening end of the protective sleeve to the other end, and the inner diameter of each sealing sleeve is adapted to the outer diameter of the tip of the corresponding syringe.

[0009] In one embodiment of this utility model, the inner diameter of the retaining ring formed by multiple retaining heads is smaller than the smallest inner diameter among the multiple sealing sleeves.

[0010] In one embodiment of this utility model, the sealing ring is shaped like a "<" and includes a connecting part connected to the edge of the protective sleeve opening and a clamping part connected to the connecting part. The connecting part is inclined toward the inside of the protective sleeve opening, and the clamping part is parallel to the plane of the protective sleeve opening in its free state.

[0011] In one embodiment of this utility model, the card head is made of elastic silicone material.

[0012] In one embodiment of this utility model, the opening and closing handle is connected to the connecting part. As the opening and closing handle is opened outward, the locking part will also open outward under the action.

[0013] In one embodiment of this utility model, the opening and closing handle is made of rubber or silicone.

[0014] As one embodiment of this utility model, the protective sleeve is generally conical, with the opening located at the bottom of the cone and the top of the cone being spherical.

[0015] The beneficial effects of adopting the above technical solution are as follows:

[0016] This utility model provides a protective device for temporary drug storage, which is used to cover the tip of a syringe to seal and preserve the drug temporarily stored inside the syringe, preventing excessive moisture loss before use. When the protective device is on the syringe tip, it is secured by a locking mechanism to prevent movement relative to the syringe. Simultaneously, a sealing ring presses against the syringe tip surface to achieve a seal at the interface. To remove the protective cover, the locking mechanism is opened outwards by turning the opening handle outwards, allowing the cover to be removed. Its structure is simple, provides good sealing, and the protective cover does not contact the interface during use, preventing drug residue and contamination. Furthermore, the protective device can be reused after rinsing. Attached Figure Description

[0033] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0034] Example 1:

[0035] like Figures 1-4 The illustrated protective device for temporary drug storage includes a cylindrical or conical transparent protective sleeve 1 with one open end and an even number of annular locking heads 2 evenly fixed at the opening. The locking heads 2 are made of flexible material, and gaps are left between adjacent locking heads 2. The multiple locking heads 2 form a locking ring that clamps a syringe 6, the inner diameter of which is smaller than the outer diameter of the syringe 6. Half of the sequentially adjacent locking heads 2 are connected to an opening / closing handle 3, and the other half are connected to another opening / closing handle 3. An annular sealing ring 4 is fixed to the inner wall of the protective sleeve 1, the inner diameter of which is smaller than the diameter of the syringe tip 6. The sealing ring 4 is made of rubber or silicone.

[0036] In this embodiment, the sealing ring 4 is <-shaped and includes a connecting portion 201 connected to the edge of the opening of the protective sleeve 1 and a clamping portion 202 connected to the connecting portion 201. The connecting portion 201 is inclined towards the inside of the opening of the protective sleeve 1, and the clamping portion 202 is parallel to the plane of the opening of the protective sleeve 1 in its free state. The protective sleeve 1 is generally conical, with the opening located at the bottom of the cone and the apex of the cone being spherical.

[0037] The protective device is used to cover the tip of syringe 6 to seal and preserve the temporarily stored medication inside syringe 6, preventing excessive moisture loss before use. When the protective device is on the syringe tip, it is secured by the clamp 2 to prevent movement of the protective sleeve 1 relative to syringe 6. Simultaneously, the outer plane of the sealing ring 4 presses and seals the tip plane of syringe 6, achieving a seal on the interface 7. When it is necessary to remove the protective sleeve 1, opening the opening handle 3 outwards will cause the clamp 2 to open outwards, thus removing the protective sleeve 1. Its structure is simple; the protective sleeve 1 will not contact the interface 7 during use, preventing medication residue and contamination. Furthermore, the silicone seal has good sealing properties, maximizing the retention of external moisture in the medication to prevent drying and inaccurate dosage during administration. After use, it can be recycled after professional cleaning. The protective sleeve 1 is made of transparent material, facilitating real-time observation of the interface 7 at the tip of syringe 6 during use and preventing the interface 7 from touching the inner wall of the protective sleeve 1. Specifically, the protective sleeve 1 is made of transparent silicone or transparent resin.

[0038] The locking head 2 is made of elastic silicone. The opening / closing handle 3 is made of rubber or silicone. The opening / closing handle 3 is connected to the connecting part 201. As the opening / closing handle 3 opens outward, the locking part 202 opens outward accordingly. The silicone locking head 2 is elastic and can be used on syringes 6 of different capacities (different diameters). When the interface 7 of the syringe 6 is located in the middle of the syringe head, the inner diameter of the sealing ring 4 is slightly larger than the diameter of the interface 7, which can seal the head plane of syringes 6 of different capacities; however, when the interface 7 is located on the side of the syringe head, unless the diameters of the various syringes 6 are not significantly different, the sealing ring 4 can only be used to seal syringes of one capacity. Figures 12-14 However, this restriction does not apply when the interface 7 is located in the middle of the tip of the syringe 6.

[0039] Example 2:

[0040] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that an annular sealing sleeve 5 is fixedly provided on the side of the sealing ring 4 near the opening of the protective sleeve 1, and the inner diameter of the sealing sleeve 5 is adapted to the outer diameter of the tip of the syringe 6. The sealing sleeve 5 is made of rubber or silicone.

[0041] By setting an annular sealing sleeve 5, a better seal can be achieved. When the sealing ring 4 is tightly fitted against the end face of the syringe 6, the sealing sleeve 5 can be tightly fitted onto the end face of the syringe 6, achieving a better seal for the interface 7. Because the sealing sleeve 5 is relatively narrow, it will not hinder the syringe 6 from being removed from and inserted into the protective sleeve 1.

[0042] In this embodiment, each protective device is applied only to syringes 6 of one capacity specification, as shown in the reference. Figure 12 , Figure 13 and Figure 15 .

[0043] Example 3:

[0044] like Figures 7-9 As shown, the difference between this embodiment and Embodiment 1 is that: multiple sealing rings 4 with different inner diameters are arranged axially along the inner wall of the protective sleeve 1. Each sealing ring 4 corresponds to a syringe 6 of a certain capacity. The inner diameter of the multiple sealing rings 4 gradually decreases from the open end of the protective sleeve 1 to the other end. The sealing rings 4 with different inner diameters are used to seal the tips of syringes 6 with different outer diameters. The inner diameter of the retaining ring formed by the multiple retaining heads 2 is smaller than the smallest inner diameter among the multiple sealing sleeves 5, that is, the retaining ring can clamp syringes 6 of various capacity specifications.

[0045] In this embodiment, a protective device can be applied to various syringes 6 with different capacities, regardless of whether the interface 7 is located in the middle or on the side of the syringe 6 tip.

[0046] Example 4:

[0047] like Figure 7 , Figure 10 and Figure 11 As shown, the difference between this embodiment and embodiment 3 is that: each of the sealing rings 4 is fixed with an annular sealing sleeve 5 on the side near the opening of the protective sleeve 1, and the inner diameter of the sealing sleeve 5 gradually decreases from the opening end of the protective sleeve 1 to the other end, and the inner diameter of each sealing sleeve 5 is adapted to the outer diameter of the tip of the corresponding syringe 6.

[0048] In this embodiment, a protective device can be applied to various syringes 6 with different capacities, regardless of whether the interface 7 is located in the middle or on the side of the syringe 6 tip.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
