[0024] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] See Figure 1 The portable liquid bandage smearing device comprises a liquid injection shell 1, an smearing head 2 and a smearing cover 3. The smearing head 2 is connected to the liquid outlet end of the liquid injection shell 1, and the other end of the smearing head 2 is connected to the smearing cover 3.

[0026] Specifically, the liquid injection shell 1 includes a shell body 101 and a shell neck 102. In the present invention, the shell body 101 is set to be flat, and a sealed bottom is pressed at the end of the shell body 101. Of course, the shell body 101 can not only be set to be flat, but also can be set to other shapes, as long as it can accommodate a certain capacity of liquid bandage. In addition, the specific capacity of the shell body 101 can also be changed according to actual needs. In order to make the liquid bandage application device easy to carry and the built-in liquid dressing can be used up at one time, the capacity of the shell body 101 is generally less than 5mL, and can be 4mL, 3mL, 2mL, 1mL or 0.5mL. Of course, the specific capacity can be adjusted according to the specific situation of the user.

[0027] The housing 101 also includes a viewing window 103 marked with scale lines. The presence of the viewing window 103 allows for a direct and clear view of the amount of dressing contained within the housing 101. Furthermore, in the present invention, the housing 101 is preferably frosted to increase surface friction, making it easier for the user to handle and carry.

[0028] Positioning protrusions 1020 are formed on the shell neck 102, and the number of positioning protrusions 1020 can be arranged according to the length of the shell neck 102. In addition, in the present invention, the inner diameter of the shell neck 102 is set to 3-8 mm to avoid excessive outflow of liquid dressing due to an excessively large inner diameter, or difficult outflow due to excessive surface tension of the liquid in the neck due to a too small diameter.

[0029] In this utility model, refer to Figure 2 The aforementioned smear head 2 includes a connecting portion 201 and an smearing portion 202, and the smearing portion 202 is sleeved on the connecting portion 201. The connecting portion 201 is used to connect the shell 101 and the smearing portion 202. The aforementioned smearing portion 202 can also be integrally formed with the connecting portion 201, and is not limited to being sleeved on the connecting portion 201, and can also be connected in other ways.

[0030] Specifically, the aforementioned connecting portion 201 is a cylinder with a hollow center, and a positioning groove 2010 is formed inside the cylinder to cooperate with the aforementioned positioning protrusion 1020. When it is necessary to connect the liquid injection shell 1 and the applicator head 2, the aforementioned positioning protrusion 1020 is pushed into the positioning groove 2010, thereby limiting and fixing the applicator head 2 on the liquid injection shell 1. Of course, in order to limit and fix the applicator head 2 on the liquid injection shell 1, it is not limited to using the positioning protrusion and the positioning protrusion to limit and fix. It is also possible to provide an external thread on the shell neck 102 and an internal thread in the aforementioned connecting portion 201, thereby achieving limit and fixation through the internal and external thread connection. Other methods that can achieve limit and fixation can also be adopted, as long as the applicator head 2 and the liquid injection shell 1 can be stably connected.

[0031] In the present invention, the front end of the aforementioned application portion 202 has an inclined application surface in order to facilitate the user in actual use, so that the wound can be in contact with the application head over the largest area, thereby improving the application effect and application uniformity of the dressing. In the embodiment of the present invention, the top of the application portion 202 is set to have an oblique angle of 30 to 60 degrees, and it is more preferable to set the application head to an oblique angle of 45 degrees for application. Of course, the specific angle can be adjusted and changed as needed. At the same time, the material of the application portion 202 can be selected from flocking, silicone or foam, or a combination of several materials. Combined with the above-mentioned oblique angle setting, it is beneficial to increase the comfort and experience of application.

[0032] A liquid outlet hole 2020 is provided at the center of the aforementioned coating surface. The aperture of the liquid outlet hole 2020 should not be too large or too small to ensure that the dressing in the liquid injection shell 1 can be discharged evenly and orderly. In an embodiment of the present invention, the aperture of the liquid outlet hole 2020 is set at 0.5mm~1mm to ensure uniform flow of the dressing. In addition, the liquid outlet hole 2020 is connected to the aforementioned connection part 201 through a curved pipe. With respect to the curved pipe, in the present invention, the pipe diameters at different positions on the pipe are not uniform, and the pipe diameters are set between 0.5mm~5mm. The pipe diameter at the connection with the aforementioned shell 101 is the largest, and the pipe diameter at the connection with the aforementioned liquid outlet hole 2020 is the smallest. That is, the pipe diameter of the curved pipe gradually decreases along the direction of liquid discharge of the dressing. In addition, setting the liquid outlet pipe as a curved pipe can increase the resistance of the liquid dressing during the liquid discharge process, buffer the liquid discharge speed of the dressing, and effectively avoid linear spraying during the liquid discharge process of the dressing, which affects the coating effect.

[0033] In this utility model, refer to Figure 3 The aforementioned smear cover 3 includes a covering portion 301, a clamping portion 302 and a lifting portion 303. The clamping portion 302 is protruding from the covering portion 301 and is integrally connected to the covering portion 301. The inner diameter of the clamping portion 302 is smaller than the inner diameter of the covering portion 301, and the inner diameter of the covering portion 301 is equal to the outer diameter of the aforementioned smearing portion 201. Therefore, when in use, the covering portion 301 is covered on the aforementioned smearing head 2, and the clamping portion 302 is pressed against the edge of the smearing head 2 to play a covering and protective role. The lifting portion 303 is arranged on both sides of the aforementioned covering portion 301 and is integrally connected to the covering portion 301. In the embodiment of the present utility model, the lifting portion 303 is set as a square taking wing to facilitate the user to grab and use. Of course, the above-mentioned taking wings are not limited to being set as square, and can also be semicircular, diamond or triangular, as long as it is convenient for the user to take.

[0034] Also, see Figure 3 A puncture column 3020 is formed inwardly in the middle of the aforementioned locking portion 302, and the top of the puncture column 3020 is a tip 3021. The tip 3021 is used to abut against the aforementioned liquid outlet hole 2020, and is used to abut the liquid outlet hole 2020 to prevent the dressing from leaking from the liquid outlet hole 2020.

[0035] The liquid injection shell 1 and the applicator cap 3 can be made of one or a combination of linear low-density polyethylene, medium-density polyethylene, high-density polyethylene, branched polyethylene, acrylonitrile-butadiene-styrene, polyamide, and polystyrene. The resulting liquid bandage applicator is soft and can be directly extruded and applied by squeezing the shell 101.

[0036] In summary, the portable liquid bandage application device in the present invention is small in size, can be contained at normal pressure, has no vacuum, is easy to carry, and is not restricted by means of transportation. It also has a comfortable application head, is easy to apply, is disposable, does not have the risk of cross infection, and has a strong sense of experience. In addition, there is a visual scale bar on the shell, the liquid output is controllable, and the application head has a fluidics design to avoid the problems of liquid spraying and too little liquid output. At the same time, it integrates application and storage in one, and the liquid output and application amount are easier to control. It breaks through the current situation where liquid bandages can only be contained in glass or aluminum materials, and increases practicality.
