Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, specifically to a chitosan powder spray bottle for hemostasis. Background Technology

[0002] The dedicated medical powder dispenser for chitosan hemostatic powder allows for the uniform, sterile, and convenient application of chitosan-based hemostatic powder to the wound surface, especially for treating irregular or difficult-to-compress bleeding wounds.

[0003] Conventional powder dispensers cannot effectively ensure that the powder is evenly covered on the wound surface during the powder application process, and powder may spill out when the cap is opened. Utility Model Content

[0004] The purpose of this invention is to provide a chitosan powder spray bottle for hemostasis. The powder sieve plate structure forces the outflowing powder to be mechanically sieved, so that the chitosan powder can cover the wound surface in a fine and uniform thin layer. This avoids the waste caused by excessive local powder thickness and also prevents uneven coverage from affecting the hemostatic effect, significantly improving the hemostatic efficiency and quality, and solving the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chitosan powder spray bottle for hemostasis, comprising a glass bottle body and an air-sealed cap, wherein the glass bottle body includes a bottle mouth, and a stopper is installed inside the bottle mouth, and a powder sieve plate is installed on the outer surface of the stopper, the powder sieve plate and the stopper are connected by a slot, and a rubber head is provided on the top of the air-sealed cap, and the interior of the rubber head is configured as a hollow cavity structure.

[0006] Preferably, a metal spring clip is provided on the inner side of the bottom of the gas-sealed bottle cap, and the gas-sealed bottle cap is connected to the bottle mouth through the metal spring clip.

[0007] The above solution achieves double sealing protection through the robust seal formed by the gas-sealed cap and the metal spring buckle, as well as the tight fit between the stopper and the bottle mouth.

[0008] Preferably, the glass bottle body has a storage cavity inside, and the storage cavity has an integrally formed flow guide rod inside, wherein the flow guide rod extends to the inside of the stopper.

[0009] The above solution, with its integrated design of the guide rod and glass bottle body, ensures the strength and durability of the core guide structure, preventing it from falling off due to long-term use or cleaning.

[0010] Preferably, the seal has a conical opening inside, and ball bearings are installed inside the opening.

[0011] The above solution uses the ball bearings inside the hopper as a dynamic anti-clogging component, further eliminating the risk of clogging the outlet due to powder caking from moisture.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the powder sieve plate structure forces the outflowing powder to be mechanically sieved, so that the chitosan powder can cover the wound surface in a fine and uniform thin layer. This not only avoids the waste caused by excessive local powder thickness, but also prevents uneven coverage from affecting the hemostatic effect, thus significantly improving the hemostatic efficiency and quality.

[0014] 2. This utility model adopts a push-type rubber head driving method, which supports one-handed operation. Medical staff or users can accurately control the powder dispensing without complicated movements. It is especially suitable for emergency hemostasis scenarios. During the entire operation, the fingers only touch the outside of the air-sealed bottle cap, avoiding contact with the bottle mouth and powder dispensing parts such as the powder sieve plate, thus minimizing the risk of contamination of the medicine powder during the operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] To address the issues of conventional powder dispensers failing to ensure even powder coverage on wound surfaces and the risk of powder spillage during opening, please refer to [link to relevant documentation]. Figure 1-3 The present invention provides the following solution:

[0021] A chitosan powder spray bottle for hemostasis includes a glass bottle body 1 and an air-sealed bottle cap 2. The glass bottle body 1 includes a bottle mouth 101, and a stopper 3 is installed inside the bottle mouth 101. A powder sieve plate 301 is installed on the outer surface of the stopper 3. The powder sieve plate 301 and the stopper 3 are connected by a slot. A rubber head 201 is provided on the top of the air-sealed bottle cap 2, and the interior of the rubber head 201 is a hollow cavity structure.

[0022] In this embodiment, the gas-sealed bottle cap 2 is tightly fastened to the bottle mouth 101 of the glass bottle body 1 by the metal spring buckle 202 on the inner side of its bottom, forming the first seal. At the same time, the sealing plug 3 installed inside the bottle mouth 101 is tightly fitted with the inner wall of the bottle mouth, forming the second sealing barrier. Together, they ensure that the chitosan powder in the storage cavity 102 is completely isolated from external moisture, maintaining its dryness and biological activity.

[0023] When it is necessary to stop bleeding from the wound, the user inverts the bottle so that the powder sieve plate 301 faces the wound. Then, the user presses the rubber head 201 on the top of the air-sealed bottle cap 2 with their finger. Since the rubber head 201 is a hollow elastic cavity structure, the pressing action will compress the air inside it. The resulting airflow passes through the gap between the guide rod 103 and the stopper 3 and enters the powder in the storage chamber 102 in the opposite direction. This disturbs the powder and breaks up the slight caking formed when it is left to stand, restoring its fluidity. On the other hand, the airflow forms a slight positive pressure in the storage chamber 102, which, together with gravity, promotes the powder to converge along the surface of the guide rod 103 and the surrounding space towards the conical opening 302 of the stopper 3.

[0024] A metal spring buckle 202 is provided on the inner side of the bottom of the gas-sealed bottle cap 2. The gas-sealed bottle cap 2 is connected to the bottle mouth 101 through the metal spring buckle 202. A storage cavity 102 is provided inside the glass bottle body 1. An integrally formed flow guide rod 103 is provided inside the storage cavity 102. The flow guide rod 103 extends to the inner side of the stopper 3. A conical structure inlet 302 is provided inside the stopper 3. A ball bearing 303 is installed inside the inlet 302.

[0025] In this embodiment, the conical structure hopper 302 inside the sealant 3 and the ball bearing 303 placed therein form a dynamic anti-blocking mechanism; when the bottle is picked up or shaken slightly, the ball bearing 303 rolls in the hopper 302, which can effectively disperse any powder that may accumulate and prevent it from forming bridges or clumps at the key outlet.

[0026] After passing through the inlet 302, the powder reaches the powder sieve plate 301. The powder sieve plate 301 is the core component for achieving uniform powder distribution. It has a large number of precise and uniform micropores. When the powder passes through these micropores under the continuous drive of air pressure and gravity, it is forced to disperse into an extremely fine and uniform particle flow, which is sprinkled out like a thin mist, thereby ensuring that the powder can cover the wound surface with a uniform thickness.
