Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a spray cover. Background Technology

[0002] Spray administration allows the drug to reach the target site instantly and be absorbed quickly. However, during administration, the drug can diffuse into the surrounding environment. On the one hand, the drug utilization rate is low, affecting the local treatment effect. On the other hand, it can be accidentally inhaled into non-target areas, such as the stomach, eyes, and ears, causing discomfort to the patient.

[0003] Therefore, we propose a spray hood. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a spray cover that overcomes the shortcomings of the prior art. It is reasonably designed, easy to use, and solves various technical problems caused by the diffusion of drugs into the surrounding environment in existing nebulized drug delivery.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spray cover, characterized in that it includes a connecting sleeve and a cover that are connected to each other, the connecting sleeve being able to be fitted onto the pressure head of a spray nozzle, the connecting sleeve having a first drug delivery hole, the first drug delivery hole being connected to the spray nozzle orifice and the cover.

[0009] Furthermore, the connecting sleeve and the cover are detachably connected.

[0010] Furthermore, a connecting plate is formed at the part where the connecting sleeve and the cover are connected, and a second drug delivery hole is formed at the part where the cover and the connecting sleeve are connected. The connecting plate is attached to the top wall of the cover and pressed in by a pressure plate. The first drug delivery hole and the second drug delivery hole are connected.

[0011] The connecting plate and the top wall are flat.

[0012] Preferably, the second administration port is waist-shaped, and a groove that mates with the connecting plate is formed between the pressure plate and the top plane of the cover. The groove is arranged parallel to the long axis of the second administration port, and the end of the groove is sealed by a sealing plate that is detachably connected to the top wall.

[0013] The pressure plate and the top wall are connected by bolts, the rubber buckles on both sides of the sealing plate are engaged with the mounting holes of the top wall, and the connecting strip at its end is movably connected to the top wall.

[0014] Furthermore, a silicone sleeve is fitted around the bottom outer periphery of the cover.

[0015] (III) Beneficial Effects

[0016] This utility model provides a spray cover with the following beneficial effects:

[0017] 1. The spray nozzle ensures that the drug is accurately applied to the target site during drug administration, while reducing or preventing the spread of the drug spray in non-target areas, improving drug utilization and ensuring the local treatment effect.

[0018] 2. Through the specific design of the connecting plate, pressure plate, and sliding groove, the connecting sleeve and the cover can be slidably engaged. During drug administration, such as head administration, the pressing operation of the spray nozzle head will only cause the connecting sleeve to slide, while the cover can remain stationary. This avoids the cover from shifting due to the pressing of the head, ensuring the accuracy of the drug administration site, and also avoids the cover from tilting due to the pressing of the head. This allows the bottom of the cover to effectively fit the skin around the drug administration site, preventing the drug from spreading into the surrounding environment. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] See attached document Figure 1-5 A spray cover includes a connecting sleeve 1 and a cover 5 connected to each other. The connecting sleeve 1 includes a sleeve part 1a, a connecting pipe 1b, and a connecting plate 1c connected sequentially from top to bottom. The connecting sleeve 1 can be fitted onto the pressure head of a spray nozzle 7. A first drug delivery hole is provided on the connecting sleeve 1. The connecting pipe 1b extends radially outward from the first drug delivery hole. The spray hole of the spray nozzle 7, the first drug delivery hole, the connecting pipe 1b, and the second drug delivery hole 5b on the top of the cover 5 are connected sequentially. The upper part of the connecting pipe 1b preferably has a tapered structure that gradually expands from top to bottom to reduce spray residue. The connecting plate 1c extends outward from the bottom contour of the connecting pipe 1b. The connecting plate 1c and the top wall 5f of the cover 5 are both flat and fit together. The connecting plate 1c and the cover 5 are detachably connected. A vent hole 5a is provided on the cover 5 to reduce the pressure difference between the inside and outside of the cover and facilitate the pressing operation of the spray nozzle.

[0048] Figure 8 shows the bottle body on which the spray nozzle is installed. During the use of the spray agent, people usually hold the bottle body 8 and press the pressure head of the spray nozzle 7 with their thumb. This operation will cause the cover 5 to move or even tilt. Therefore, this embodiment not only designs the connecting sleeve 1 and the cover 5 as separate structures, but also designs the connecting sleeve 1 and the cover 5 as structures that can slide relative to each other.

[0049] In this embodiment, the connecting plate 1c and the top wall 5f of the cover 5 are press-fitted by the pressure plate 3. The bolt 2 passes through the pressure plate 3 and is threadedly connected to the first mounting hole 5c, i.e., the threaded hole. A U-shaped opening 3a is formed on the pressure plate 3. A groove 3b (specifically formed by the indentation of the plate) is formed between the plate body on both sides of the U-shaped opening 3a and the top wall of the cover 5. The groove 3b is parallel to the long axis of the second drug delivery hole 5b. The end of the groove 3b is sealed by a sealing plate 4 that is detachably connected to the top wall 5f. The two sides of the connecting plate 1c extend into the groove 3b and slide in cooperation with the groove 3b. The connecting pipe 1b passes through the U-shaped opening 3a from top to bottom and is guided in cooperation with the U-shaped opening 3a.

[0050] The second administration port 5b is waist-shaped, and an arc-shaped opening is formed on the inner side of the sealing plate 4. The arc-shaped opening and the U-shaped opening 3a are joined together to form a waist-shaped hole with the same shape as the second administration port 5b.

[0051] The pressure plate 3 and the top wall 5f are connected by bolts 2. The rubber clips 4a on both sides of the sealing plate 4 are engaged with the second mounting holes 5d of the top wall 5f, and the connecting sleeve 4b at its end is movably connected to the top wall 5f (the connecting sleeve 4b is made of rubber and has a step at its root to prevent it from coming out of the third mounting hole 5e of the top wall 5f). When the sealing plate 4 is pulled upward, the rubber clips 4a disengage from the second mounting holes 5d and then flip outward with the connecting sleeve 4b to open the groove 3b, allowing the connecting sleeve 1 to come out.

[0052] In this embodiment, a silicone sleeve 6 is fitted around the bottom outer periphery of the cover 5. Preferably, the lower edge of the silicone sleeve 6 is lower than the lower edge of the cover 5, so as to better fit the skin around the drug administration site.
