[0002] Pediatrics is a discipline of clinical medicine, and its research object is children from fetus to adolescence. It is a medical science that studies the growth and development laws of children and adolescents, and improves the physical and mental health levels and the quality of disease prevention and treatment of children and adolescents. The objects it treats are in the growth and development period, especially in the infancy period, and are very prone to skin diseases such as eczema, chickenpox, scabies, prickly heat, and impetigo. When treating the skin diseases of infants, in order to avoid affecting the physical health of infants, external medications are usually used for treatment. Most of these external medications are in the form of emulsion or paste. In the existing drug application operation, it is usually necessary to first squeeze out the ointment by hand during the drug application process, and then use a cotton swab or a wiping cotton to dip the drug for application. The operation is inconvenient, and in this process, the drug needs to be dipped many times, which is likely to cause infection to the unused drug. In addition, some skin diseases often have a large affected area and require large-area drug application. At this time, using a cotton swab or a wiping cotton to dip and apply the drug is cumbersome, time-consuming and laborious, and very inconvenient. During the application process, it is also necessary to ensure requirements such as uniform application, no damage to the skin during application, and comfortable application.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Such as Figure 1-6As shown in the figure, a drug application device for clinical use proposed by the present invention includes an application component, a component mounting box 3, a bottom sleeve box 7, a medicine box 1, and a control box 2;

[0028] The application component includes an application part mounting rubber block 4, a height-limiting rolling ball 421, a smoothing motor 8, and a smoothing plate 81. The bottom of the mounting rubber block 4 is provided with spherical grooves 42 in an array and staggered manner. The spherical grooves 42 are filled with movable height-limiting rolling balls 421. Each spherical groove 42 is provided with an insertion hole penetrating through the application part mounting rubber block 4. A first medicine supply pipe 422 is inserted into the insertion hole. The lower surface of the application part mounting rubber block 4 in the space between the spherical grooves 42 is movably clamped with a smoothing plate 81. A smoothing motor 8 is inserted into the application part mounting rubber block 4 directly above each smoothing plate 81. The smoothing plate 81 is sleeved on the rotating shaft of the smoothing motor 8. The height of the smoothing plate 81 exposed from the lower surface of the application part mounting rubber block 4 is 2 - 3 mm smaller than the height of the height-limiting rolling ball exposed from the lower surface of the application part mounting rubber block 4. The upper surface of the application part mounting rubber block 4 is an arc surface. An inner frame 41 is embedded in the circumferential wall of the application part mounting rubber block 4 near the top. The inner frame 41 is an arc-shaped frame and matches the radian of the arc surface;

[0029] Before application, there is no ointment in the medicine box 1, and the application component is clean. Ointment is injected into the medicine box 1, and the medicine injection plug 11 is plugged in to preheat the ointment. During application, pressurization is started, and the ointment flows into the spherical grooves 42. When it is seen that ointment flows out, the height-limiting rolling ball 421 at the bottom of the application part mounting rubber block 4 is attached to the skin, but it cannot be pressed. The ointment will slowly adhere to the skin. Then, in combination with the smoothing motor 8 driving the smoothing plate 81 to rotate, the ointment is smoothed. Since the smoothing plate 81 does not contact the skin (2 - 3 mm or 1 - 2 mm away from the skin), if the skin does not hurt during the rolling process of the height-limiting rolling ball 421, the rotation of the smoothing plate 81 can be cancelled, and the height-limiting rolling ball 421 is used to roll back and forth for application, which will be more uniform. Since rolling back and forth will exert pressure on the skin and cause pain, in order to reduce the rolling frequency, the slowly rotating smoothing plate 81 is started to smooth.

[0030] A bent arc component is installed in the component mounting box 3. The inner frame 41 is installed on the bent arc component. The lower half of the application part mounting rubber block 4 exposes the bottom of the component mounting box 3. A handle 30 is installed on one side wall of the component mounting box 3;

[0031] The inner frame 41 is bent upward, so that the application part mounting rubber block 4 bends upward and the bottom becomes an arc surface. When smoothing the arm or thigh, the contact area will increase.

[0032] At the top of the medicine box 1, there is a booster pump 121 and a medicine injection plug 11. The air outlet pipe of the booster pump 121 penetrates from the top of the medicine box 1 to the inside. The booster pump 121 is sheathed with a protective sleeve 12. The medicine injection plug 11 is inserted into the medicine injection hole at the top of the medicine box 1. At the bottom of the medicine box 1, there are multiple fine medicine discharge pipes 13. The bottom of the medicine box 1 is fixed on the top of the component installation box 3, and the fine medicine discharge pipes 13 penetrate the top of the component installation box 3. Each of the fine medicine discharge pipes 13 is correspondingly connected to each first medicine supply pipe 422 through a hose;

[0033] The boosting intensity of the booster pump is used to adjust the speed of applying the ointment, that is, the speed of discharging the ointment.

[0034] The control box 2 is installed beside the medicine box 1 on the top of the component installation box 3. The bottom sleeve box 7 can be sleeved on the lower half of the applicator installation rubber block 4. When not in use, the bottom sleeve box 7 can be sleeved on the lower half of the applicator installation rubber block 4 to prevent surface contamination by bacteria.

[0035] The arc-shaped component includes two symmetrically arranged inverted L-shaped plates 5, two limit slide bars 62, a bidirectional lead screw 61 and a servo motor 6. The two inverted L-shaped plates 5 are symmetrically installed on both side edges of the square metal frame 41 and fixed by screwing bolts 51 from the side wall of the inverted L-shaped plate 5 into the side edge of the square metal frame 41. Both ends of the two limit slide bars 62 are fixed on the inner wall of the component installation box 3. The two ends of the horizontal plates of the two inverted L-shaped plates 5 are movably sleeved on the two limit slide bars 62. The bidirectional lead screw 61 spirally penetrates through the middle positions of the horizontal plates of the two inverted L-shaped plates 5. Both ends of the bidirectional lead screw 61 are rotatably installed on the inner wall of the component installation box 3. A servo motor 6 is installed at one end of the bidirectional lead screw 61.

[0036] By changing the rotation direction of the servo motor 6, the rotation direction of the bidirectional lead screw 61 is changed, so as to adjust the relative movement or separation of the two symmetrically arranged inverted L-shaped plates 5. When moving towards each other, the applicator installation rubber block 4 is squeezed against the upward arc edge. The lower surface is an arc surface, and the arc surface gradually becomes larger. On the contrary, when moving away from each other, the arc surface becomes smaller until it becomes a flat surface.

[0037] The thickness of the applicator installation rubber block 4 is 1.5 - 2.0 cm. The widths of the four sides of the applicator installation rubber block 4 are all 5 - 7 cm. The maximum height of the upward bending of the applicator installation rubber block 4 does not exceed 5 mm.

[0038] 3 - 4 height-limiting rolling balls 421 can be installed in a row. There cannot be too many, as the skin area of children is small and the flatness of the skin surface changes quickly. By designing a smaller applicator installation rubber block 4, it can also be quickly applied. If the bending arc cannot fit the skin, it can be applied multiple times, cancel the work of the spreading plate, and slowly apply it using the height-limiting rolling balls 421, mainly for the thin part of the arm.

[0039] The spreading motor 8 is a micro motor, with a height of 10 - 12 mm and an outer diameter of 8 - 15 mm. There are such small motors on the market. The small size of the motor facilitates installation, and during the spreading and leveling process, the force will not be too large.

[0040] A rubber sleeve 811 is sleeved on the bottom wall and the side wall of the spreading plate 81. This can make the spreading comfortable. After the spreading is completed, the sterilized rubber sleeve 811 can be directly replaced, which is convenient and has a low cost, without the need for cleaning and sterilization.

[0041] The height-limiting rolling ball 421 is a glass ball, with a diameter of 6 - 10 mm. The glass ball is easy to roll, does not hurt the skin, and has weak adhesion to the ointment, which is convenient for spreading.

[0042] The inner diameter of the medicine-discharging thin tube 13 is 2 - 3 mm, and the inner diameter of the first medicine-supply tube 422 is 3 - 4 mm.

[0043] The medicine-discharging thin tube 13 cannot be too thick to prevent the ointment from falling automatically. If it is thin, the ointment will only be extruded under increased pressure. And the position of the first medicine-supply tube 422 at the bottom cannot be completely inserted into the spherical groove 42. When it is squeezed and deformed, the insertion hole will be deformed. Appropriately increasing the aperture is convenient for the flow of the ointment.

[0044] A heat-preserving heating wire is provided on the outer wall of the medicine box 1. The ointment is heated to a temperature close to the human body temperature before spreading, making the spreading more comfortable.

[0045] A storage battery is provided inside the grip 30, and the storage battery supplies power to the control box. There is no need for an external power supply, and it only needs to be charged regularly.

[0046] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
