Description

Technical Field

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

[0002] Hemostatic adhesives are medical adhesives developed based on biomaterials or synthetic polymer technology, primarily used for rapid wound closure, bleeding control, and promoting healing. The core components of hemostatic adhesives are diverse, including fibrin glue, chitosan, and cyanoacrylate derivatives. Some products also contain clotting factors, calcium ions, or antibacterial agents to enhance their function. They have a wide range of applications, providing a convenient solution in surgical procedures and trauma emergency care.

[0003] In existing technologies, hemostatic adhesives are mostly applied using syringes or manually. Manual application inevitably involves contact with the wound surface, which can easily lead to wound infection, and it is difficult to control the thickness of the adhesive layer. In addition, there are also application devices that combine a ballpoint pen tip structure with a syringe cartridge structure for application, but these devices are not suitable for hemostatic adhesives that require mixing with different media or ingredients, or for situations where the hemostatic adhesive is mixed with other agents. Furthermore, the spherical structure of the application end of such devices can easily result in an adhesive layer that is thinner in the middle and thicker at the edges, which is not conducive to the coagulation and hemostasis of the adhesive.

[0004] Based on this, this application proposes a hemostatic glue roller device to solve at least one or more of the problems mentioned above. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. 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.

[0037] This application provides a hemostatic glue roller device, which solves the problem in the prior art that hemostatic glue application devices are difficult to support the mixing of effective hemostatic glue and / or the mixing of hemostatic glue with other agents.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] Example 1:

[0040] See Figures 1-2 As shown, the present invention provides a hemostatic adhesive roller device, comprising: a cylindrical structure 1, having at least two independent cavities 11 inside for storing medicine, and a medicine outlet 12 at one end of the cylindrical structure 1; a drug delivery mechanism 2, disposed at the end of each cavity 11 away from the medicine outlet 12; a mixing cavity 3, disposed inside the cylindrical structure 1 and connected to each cavity 11 and the medicine outlet 12; and a mixing mechanism 4, disposed inside the mixing cavity 3 for mixing the medicine entering the mixing cavity 3 from each cavity 11.

[0041] It should be noted that when medical personnel use this device, they should first add hemostatic glue or a drug to be mixed with hemostatic glue into the cavity 11 as needed, or a hemostatic glue that takes effect by mixing multiple components, such as mixing liquid and powder; the drug delivery mechanism 2 can deliver the drug inside the cavity 11 into the mixing chamber 3, such as by using a piston to push it in; after the drug enters the mixing chamber 3 and is fully mixed under the action of the mixing mechanism 4, it flows out through the drug outlet 12 for application.

[0042] See Figure 2 As shown, in a preferred embodiment, the drug delivery mechanism 2 includes: at least two push rods 21, each push rod 21 being slidably connected within each cavity 11; and a fixing member 22, which is disposed at the end of each push rod 21 away from the drug outlet 12, and each push rod 21 being detachably connected to the fixing member 22.

[0043] It should be noted that: by pressing the push rod 21, the agent inside the cavity 11 is pushed into the mixing cavity 3. By pressing the fixing part 22, all the push rods 21 can be moved, which facilitates the injection of the agent. The push rods 21 are detachably connected to the fixing part 22, for example, by using a snap-fit ​​structure or an interference fit fixing post for mutual connection.

[0044] See Figure 3 As shown, in a more preferred embodiment, each push rod 21 is configured as a set of rods of different lengths adapted to the mixing ratio of the agent.

[0045] It should be noted that when it is necessary to adjust the mixing ratio of the medicine, medical staff can replace the push rod 21 of different lengths on the fixing part 22 for injection. By using the fixing part 22 to push the push rod 21 at the same time, different proportions of medicine can be pushed into the mixing chamber according to the length of the push rod 21, which is quick and convenient.

[0046] Example 2:

[0047] See Figure 4As shown, the present invention provides a hemostatic glue roller device, including the contents of Embodiment 1 and its preferred embodiments. In addition, the mixing mechanism 4 also includes: a fixing rod 41, which is disposed in the mixing chamber 3; and a fan blade 42, which is rotatably connected to the fixing rod 41.

[0048] It should be noted that: the fan blade 42 is rotatably connected to the fixed rod 41, such as by using a bearing structure or the like; when the agent enters the mixing chamber 3 from the cavity 11 under the action of the push rod 21, the agent pushes the fan blade 42 to rotate, so that the fan blade 42 rotates to mix the agent that has entered the mixing chamber 3, and the fixed rod 41 is used to limit the fan blade 42.

[0049] Example 3:

[0050] See Figure 4 As shown, the present invention provides a hemostatic glue roller device, including the contents of Embodiments 1-2 and their preferred embodiments. In addition, a coating mechanism 5 is provided at one end of the cylindrical structure 1 near the drug outlet 12.

[0051] It should be noted that the application mechanism 5 can apply the mixed hemostatic agent to the wound surface relatively evenly. For example, it can adopt a brush structure, a partition with multiple round holes evenly distributed, or a thin film structure that allows the agent to penetrate.

[0052] See Figure 4 As shown, in a preferred embodiment, the coating mechanism 5 includes a roller 51, which is rotatably connected to the inner surface of the mixing chamber 3, and the outer surface of the roller 51 extends out of the drug outlet 12.

[0053] It should be noted that after the medicine is mixed in the mixing chamber 3, it falls onto the outer surface of the roller 51 and rolls away from the mixing chamber 3 and the medicine outlet 12. Medical staff can apply the hemostatic glue through the roller 51, which can evenly apply the hemostatic glue and facilitate the rapid coagulation of the hemostatic glue to stop bleeding. Medical staff do not need to touch the wound surface, thus avoiding the risk of infection.

[0054] Example 4:

[0055] See Figure 4 As shown, the present invention provides a hemostatic glue roller device, including the contents of embodiments 1-3 and their preferred embodiments. In addition, a one-way valve 111 is provided at one end of each cavity 11 near the mixing cavity 3.

[0056] It should be noted that the one-way valve 111 is used to prevent the mixed medicine in the mixing chamber 3 from flowing back into the chamber 11 and causing contamination, which would interfere with the normal use of the device.

[0057] Example 5:

[0058] The present invention provides a hemostatic adhesive roller device, including the contents of embodiments 1-4 and their preferred embodiments. In addition, the cylindrical structure 1 is made of transparent material and has scale markings on its outer surface.

[0059] It should be noted that medical staff can quickly and intuitively observe the drug status inside cavity 11 and mixing cavity 3 through the transparent material of the cylindrical structure and the setting of scale markings, which facilitates timely addition of drugs and observation of the mixing status.

[0060] See Figure 5 As shown, in a preferred embodiment, the outer surface of the cylindrical structure 1 is provided with a gripping portion 13.

[0061] It should be noted that the grip part 13 has a concave or anti-slip texture, which makes it easier for medical staff to grip the device.

[0062] See Figure 5 As shown, in a preferred embodiment, the end of the fixing member 22 away from the push rod 21 is provided with a pressing block 23.

[0063] It should be noted that the pressing block 23 is made of rubber, which has a non-slip effect and makes it easy for medical staff to press and use.

[0064] In summary, compared with existing technologies, it has the following beneficial effects:

[0065] 1. This utility model, by setting multiple cavities, drug delivery mechanism, mixing cavity and mixing mechanism within a cylindrical structure, enables different drugs to be placed in the multiple cavities for use in combination with hemostatic glue, or for use with hemostatic glue that is compatible with different media and different components to achieve the effect of mixing, making it more versatile than the prior art.

[0066] 2. By setting up a fixing component, a push rod, and a detachable connection between the above components, medical staff can replace push rods of different lengths on the fixing component to inject the medication. Different proportions of medication can be pushed into the mixing chamber according to the length of the push rod, making the operation quick and convenient.

[0067] 3. This utility model, by setting up an application mechanism (roller), can evenly apply hemostatic adhesive, which facilitates rapid coagulation and hemostasis. Medical staff do not need to touch the wound, thus avoiding the risk of infection.

[0068] 4. This utility model improves the convenience of the device and the work efficiency of medical staff by setting a one-way valve, a transparent cylindrical structure, scale markings, a grip part and a pressing block.
