Description

Technical Field

[0001] The utility model relates to the technical field related to product packaging, in particular to a packaging device for skin wound dressings. Background Art

[0002] For a long time, due to reasons such as abrasions, traumas, burns, surgical incisions, diabetic ulcers, etc., incidents of skin damage have occurred frequently. Wound healing and tissue repair are complex processes, and wound dressings play an important role in this process. As a temporary skin substitute, dressings can play roles such as protecting the wound surface, stopping bleeding, and preventing infection. Traditional dressings, such as gauze, cotton pads, bandages, etc., are generally used to cover the wound surface and passively absorb wound exudates, and can only provide limited protection for the wound surface, only playing a physical protection role and having no promoting effect on wound healing. In order to meet people's needs, powdered biological dressings are widely used, but this type of dressing has high requirements for the storage environment, so a special sealed storage device is needed.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number 202321915177.5 discloses a packaging device for skin wound dressings, including a material tank. An inner wall of an opening of the material tank is fixedly connected with a clamping groove, a clamping head is tightly clamped in the clamping groove, a blocking cover is fixedly connected to the clamping head, a fixed sealing cover is fixedly connected to the blocking cover, multiple groups of uniformly distributed first discharge ports are arranged in the fixed sealing cover, an installation hole is arranged in the fixed sealing cover, a lifting rod is slidably connected in the installation hole, one end of the lifting rod is fixedly connected with a sliding sealing cover, a second discharge port is arranged in the sliding sealing cover, and the first discharge port and the second discharge port are arranged in an intersecting manner, but there are still the following defects:

[0004] (1) In the above patent document, by pressing a button to push the lifting rod and the sliding sealing cover to control the opening and closing of the material tank, the dressing in the material tank is discharged through the first storage tank and the second discharge pipe. However, during the process of closing the sliding sealing cover after discharging, if there is residual dressing in the cavity between the sliding sealing cover and the fixed sealing cover, it will cause the sliding sealing cover to not close completely, allowing the dressing to be in long-term contact with the outside air, accelerating the contamination and deterioration of the dressing;

[0005] In the above patent document, the powdered dressing in the material tank is taken out through the first discharge port and the second discharge port. When the patient's wound surface is on an easily observable skin area, the wound surface can be directly covered. However, if the patient is in a bedridden state and cannot make large-amplitude turning movements, it is impossible to directly pour the dressing to cover the wound surface that is not easily observable, making the dressing change difficulty for bedridden patients still relatively large.

[0006] Therefore, we make improvements on this and propose a packaging device for skin wound dressings. Content of the Utility Model

[0007] The object of the present utility model is to overcome the above deficiencies and provide a packaging device for skin wound dressings. Currently, by pressing a button to push the lifting rod and sliding the sealing cover to control the opening and closing of the material tank, the dressing in the material tank is discharged through the first storage tank and the second discharge pipe. However, during the process of closing the sliding sealing cover after discharging, if there is residual dressing inside the cavity between the sliding sealing cover and the fixed sealing cover, the sliding sealing cover cannot be completely closed, resulting in the dressing being in long-term contact with the external air, accelerating the contamination and deterioration of the dressing. The powder dressing in the material tank is taken out through the first discharge port and the second discharge port. When the patient's wound is on an easily observable skin area, the wound can be directly covered. However, if the patient is in a bedridden state and cannot perform large-amplitude turning movements, the dressing cannot be covered on the difficult-to-observe wound by direct pouring, making the dressing change for bedridden patients still difficult.

[0008] The object of the present utility model is achieved as follows:

[0009] A packaging device for skin wound dressings, including a storage tank, further comprising:

[0010] A sealing assembly, arranged on the outer wall of the storage tank for sealing the storage tank. Among them, the sealing assembly includes a top cover threadedly connected to the top wall of the storage tank and a bottom cover threadedly connected to the bottom wall of the storage tank, and the top cover and the bottom cover extend inward through the outer wall of the storage tank;

[0011] A blanking assembly, slidably connected to the inner wall of the top cover for quantitatively taking out the dressing to be used;

[0012] A material conveying assembly, arranged on the inner wall of the top cover for spraying the quantitatively taken dressing onto the wound;

[0013] A gas compression assembly, arranged on the top wall of the top cover for compressing and conveying the air flow required for spraying the material;

[0014] A gas conveying assembly, arranged on the inner wall of the bottom cover for releasing the air flow required for spraying the dressing.

[0015] Further, the blanking assembly includes a blanking button slidably connected to the inner wall of the top cover, a through pipe opening formed on the top wall of the blanking button, a first return spring slidably connected to the inner wall of the blanking button, and a blanking bin slidably connected to the inner wall of the top cover. The first return spring pushes the blanking button upward.

[0016] Further, the material conveying assembly includes a material conveying bin arranged inside the top cover and a material conveying pipe fixedly connected to the top wall of the material conveying bin. When the blanking bin is reset, it is connected to the inside of the material conveying bin. The material conveying pipe is connected to the inside of the material conveying bin, and the material conveying pipe extends outward through the through pipe opening.

[0017] Further, the air compression assembly includes an air compression chamber disposed on the top wall of the top cover, an air compression cover slidably connected to the inner wall of the air compression chamber, a second return spring fixedly connected to the inner wall of the air compression chamber, a first air duct fixedly connected to the outer wall of the air compression chamber, and a one-way intake valve fixedly connected to the outer wall of the air compression chamber. The second return spring pushes the air compression cover to move outward from the air compression chamber. The first air duct and the one-way intake valve are connected to the inside of the air compression chamber, and the first air duct extends inward through the outer wall of the bottom cover.

[0018] Further, the air delivery assembly includes a buffer air chamber disposed on the inner wall of the bottom cover, a second air duct fixedly connected to the top wall of the buffer air chamber, and a one-way exhaust valve fixedly connected to the output end of the second air duct. The buffer air chamber is connected to the inside of the first air duct, the buffer air chamber is connected to the inside of the second air duct, and the one-way exhaust valve is fixedly connected to the bottom wall of the material delivery bin and is in communication with the inside of the material delivery bin.

[0019] Compared with the prior art, the present utility model provides a packaging device for a skin wound dressing, having the following beneficial effects:

[0020] (1) By inverting the storage tank in the present utility model, the powder dressing inside the storage tank converges at one end of the storage tank near the top cover. Pressing the feeding button pushes the feeding bin to move into the storage tank, so that the powder dressing in the storage tank enters the feeding bin. After the feeding is completed, the first return spring pushes the feeding bin to reset, so that the powder dressing in the feeding bin enters the material delivery bin, realizing automatic sealing while controlling the feeding amount, avoiding the dressing from deteriorating quickly due to long-term exposure to air and waste caused by excessive feeding, and solving the problem that the sliding sealing cover in the prior art cannot be completely closed, resulting in the dressing being in long-term contact with the outside air, accelerating the pollution and deterioration of the dressing.

[0021] (2) By arranging the feeding pipe to point to the wound to be covered, pressing the air compression cover makes the air inside the air compression chamber enter the buffer air chamber through the first air duct. The gas is compressed in the buffer air chamber and is sprayed into the material delivery bin through the second air duct and the one-way exhaust valve. The powder dressing in the material delivery bin is dispersed by the high-speed air flow and enters the feeding pipe along with the flow of the high-speed air flow and is finally sprayed onto the wound to be covered, realizing directional covering of the patient's wound and solving the problem that in the prior art, the dressing cannot be covered on the wound that is not easy to observe by direct pouring, resulting in a still large difficulty in dressing change for bedridden patients.

[0040] Working principle:

[0041] The utility model provides a packaging device for skin wound dressings. When in use, first invert the storage tank 1 so that the powder dressing inside the storage tank 1 converges at one end of the storage tank 1 close to the top cover 2. Press the feeding button 3. While the feeding button 3 compresses the first return spring 32, it drives the feeding bin 33 to move into the storage tank 1. When the feeding bin 33 moves out of the top cover 2, the powder dressing in the storage tank 1 enters the feeding bin 33. Release the feeding button 3 to make the first return spring 32 push the feeding button 3 and the feeding bin 33 to reset. After complete reset, the powder dressing in the feeding bin 33 enters the material storage bin 4, completing the preparation work before wound spraying, enabling the device to be automatically fully enclosed while controlling the feeding amount, avoiding the dressing from deteriorating quickly due to long-term exposure to air and waste caused by excessive feeding. Hold the storage tank 1 and point the material conveying pipe 41 at the wound to be covered. Press the air pressure cover 51 with a finger so that the air inside the air pressure chamber 5 is squeezed and enters the buffer gas chamber 6 through the first gas guide pipe 53, causing the gas to be compressed in the buffer gas chamber 6 and sprayed into the material storage bin 4 through the second gas guide pipe 61 and the one-way exhaust valve 62. The powder dressing in the material storage bin 4 is dispersed by the high-speed gas flow and sprayed onto the wound to be covered along with the flow of the high-speed gas flow through the material conveying pipe 41, completing the directional covering of the patient's wound. After a single covering is completed, release the air pressure cover 51 to make the second return spring 52 push the air pressure cover 51 to move back to its original position. During the reset process, due to the increase in the internal space of the air pressure chamber 5, the outside air enters the air pressure chamber 5 through the one-way intake valve 54, completing the replenishment of the feeding gas.

[0042] The above are only specific application examples of the utility model, which do not constitute any limitation to the protection scope of the utility model. Any technical solutions formed by equivalent transformation or equivalent replacement fall within the scope of the protection of the rights of the utility model.
