Description

Technical Field

[0001] This utility model relates to the field of injection devices, specifically a two-in-one device for injecting and atomizing two-component liquids. Background Technology

[0002] In modern warfare, the widespread use of high-energy, high-explosive weapons results in severe tissue damage and complex injuries, leading to massive bleeding, exudation from complex wounds, and infection—all of which seriously threaten the lives of wounded soldiers. Traditional hemostatic and protective materials are no longer sufficient to treat these complex injuries. Therefore, researchers have developed novel two-component, multi-purpose materials. These two-component gel materials can be injected into deep wounds to treat massive bleeding or sprayed onto irregular wounds for hemostasis and protection. To facilitate the convenient use of two-component materials in field environments, a dual-cylinder injection and atomization device needs to be developed. This device can mix the two liquid components and rapidly inject them into the wound or spray them onto the wound surface. This technology can efficiently and conveniently stop bleeding in deep wounds or superficial skin wounds in battlefield environments, providing rapid hemostasis for wounded soldiers and creating more time for treatment.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.

[0020] An embodiment of the dual-component liquid injection atomizing device of this utility model is shown below. Figure 1 As shown, the device includes a storage tube 1, a push rod 2, a tube plug 3, an injection head 4, and an atomizing head 5. The push rod 2 can be inserted into the storage tube 1 to push out the liquid inside the storage tube 1. The tube plug 3, injection head 4, and atomizing head 5 can be installed on the top of the storage tube 1, or both injection head 4 and atomizing head 5 can be installed simultaneously. The tube plug 3, injection head 4, and atomizing head 5 are connected to the storage tube 1 in the same way.

[0021] Figure 2 This is a schematic diagram of the storage pipe 1. The storage pipe 1 has two storage chambers 11 arranged side by side. Each storage chamber 11 has a retaining ring 12 at its bottom to prevent the push rod 2 from coming out of the storage pipe 1 during use. The top of the storage chamber has an outlet 13 with two connecting holes that can connect to the two storage chambers respectively. Each side of the outlet has an upper retaining groove 14, a lower retaining groove 15, an upper retaining strip 16, and a lower retaining strip 17. The bottom of the storage pipe 1 has a raised edge 18 for easy gripping during use. In addition, the storage pipe 1 is preferably made of transparent material to make it easy to see the amount of liquid stored in the storage chamber and facilitate installation. At the same time, the inner diameters of the two storage chambers can be the same or different. Storage chambers with different inner diameters can be used to meet the different dosage requirements of two different liquid components.

[0022] Figure 3 The diagram shows push rod 2, which has a dual-push-head structure capable of simultaneously pushing out two liquids. Each push head 21 has a retaining plate 22 and a piston 23 at its top. The piston 23 has a mounting hole 24 at its bottom, and the retaining plate 22 and piston 23 are nested together through the mounting hole 24. The piston is made of a soft material. Additionally, a push handle 25 can be provided at the tail of the push rod for hand-held pushing.

[0023] Figure 4This is a schematic diagram of the installation of the pipe plug 3. The pipe plug 3 includes an inner plug 31 and a connector 32. The inner plug 31 is provided with two plug blocks 33, which can be inserted into two connecting holes on the outlet 13 of the storage pipe 1 to achieve the function of sealing two liquids. The connector 32 includes an inner hole 34, a baffle 35, and a stop block 36. The inner hole 34 is nested with the inner plug 31 and can rotate relative to each other, but will not fall out. The baffle 35 is symmetrically arranged, and its thickness transitions from thin to thick. The pipe plug 3 is fixedly connected to the storage pipe 1 through the connector 32. In specific installation, after inserting the pipe plug 3 into the storage pipe 1, press it all the way down, and rotate the pipe plug 3 clockwise. The baffle 35 and the lower locking groove 15 on the storage pipe 1 will gradually lock together. When it contacts the lower stop bar 17 on the storage pipe 1 and cannot be rotated, the connection and installation are completed. In addition, the tube plug 3 is preferably provided with a handle 37 for rotating, pressing and pulling out the tube plug 3.

[0024] Figure 5 This is a schematic diagram of the installation of the injection head 4. The injection head 4 has a connector at its bottom, which has the same structure as the connector 32 of the nozzle plug 3. The injection head 4 is connected to the outlet 13 of the storage tube 1 through the inner hole of its bottom connector, and the connection method is the same as that of the nozzle plug 3. In addition, several reinforcing ribs 41 can be provided in the middle of the injection head 4 to provide reinforcement and facilitate hand-held rotation during installation.

[0025] Figure 6 This is a schematic diagram of the installation of the atomizing head 5. The bottom of the atomizing head 5 is equipped with a connector, which is the same as that of the injection head 4. The atomizing head 5 is connected and installed by inserting it into the outlet 13 of the storage tube 1 through the inner hole of its bottom connector. The connection method is the same as that of the tube plug 3.

[0026] Figure 7 This diagram illustrates the nested installation of injection head 4 and atomizing head 5. The connection methods are identical, except that injection head 4 is installed in the lower slot 15, and atomizing head 5 is installed in the upper slot 14. During use, without removing injection head 4, atomizing head 5 can be directly nested onto injection head 4, facilitating quick switching between injection and spray functions.

[0027] All components of this two-component liquid injection atomizing device can be made of medical-grade plastic to prevent rusting, failure, and contamination. It also facilitates mold production and is lightweight, making it convenient for transportation and carrying.

[0028] The filling and use method of this utility model's two-component liquid injection atomizing device is as follows: Remove the tube plug 3, pull the push rod 2 to its limit, inject the two liquids into the two storage chambers 11 of the storage tube 1 respectively using a syringe, push the push rod 2 in to purge excess gas, and then install the tube plug 3. In use, first remove the tube plug 3, then install the injection head 4 or atomizing head 5 as needed, or a combined nested installation of the injection head 4 and atomizing head 5. Push the push rod 2 in, and the two liquids will be mixed and injected or sprayed.

[0029] This utility model discloses a two-component liquid injection atomizing device with a simple structure, which is convenient and quick to manufacture, install and use. It can safely, quickly and conveniently deliver liquid to the hemostatic site to achieve the effect of rapid hemostasis.
