Description

Technical Field

[0001] This utility model relates to the technical field of ointment application devices, specifically a convenient tube-type ointment application device. Background Technology

[0002] Dermatology is a branch of medicine that focuses on the prevention, diagnosis, and treatment of diseases of the skin, hair, nails, and related conditions. Dermatology covers a wide range of diseases, from common skin conditions to complex skin cancers and skin manifestations of systemic diseases. During dermatological treatment, ointments are often applied to the patient's wounds.

[0003] In the treatment of skin diseases, the method of direct administration of medication to the lesion site is mostly adopted. Existing ointment application methods often involve applying the ointment directly by hand. When applying ointment manually, the application efficiency is low. Since the wounds of skin patients are relatively fragile, excessive application force can cause wounds (especially when the patient has an infectious skin disease). Direct application by hand can also cause infection of the hands of the person applying the ointment. Therefore, we propose a convenient tube-type ointment application device. Utility Model Content

[0004] To address the shortcomings of existing convenient tubular ointment application devices, this utility model provides a convenient tubular ointment application device. It features a coating roller that drives a dispensing trough to draw in an equal amount of ointment, and a baffle that causes the dispensing trough to expel the ointment at the application site, ensuring sufficient ointment absorption. At the same time, the coating roller and dispensing trough improve the uniformity of ointment application when applying it to wounds, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a convenient tube-type ointment application device, including an ointment tube, a nut threadedly fitted to the lower end of the ointment tube, a lead screw installed on the internal thread of the nut, a pressure plate movably fitted on the inner side of the lead screw, a connecting sleeve threadedly installed at the end of the ointment tube, a spray head fixedly connected to the end of the connecting sleeve, a coating roller and an inner roller installed inside the spray head through a limiting clamp, a filling groove fixedly connected at equal intervals to the outside of the coating roller, and a mounting plate fixedly connected to one side of the inner roller.

[0006] Preferably, the inside of the ointment tube is filled with ointment, and the pressure plate is sleeved inside the ointment tube.

[0007] Preferably, a piston is mounted on the inner side of the pressure plate via a spring, and the piston is in contact with the ointment.

[0008] Preferably, a baffle is fixedly connected to the outside of the inner roller, and the baffle is attached to the inner side of the injection groove.

[0009] Preferably, the limiting sleeve includes a mounting sleeve, one side of the coating roller and the inner roller is sleeved inside the mounting sleeve, the mounting sleeve is laterally sleeved inside the spray head, and a first fastening bolt is installed inside the mounting sleeve, the first fastening bolt passes through the mounting sleeve and is threaded inside the spray head.

[0010] Preferably, a second fastening bolt is installed inside the mounting plate, the second fastening bolt passing through the mounting plate and in contact with the outside of the mounting sleeve.

[0011] Preferably, the ointment tube and the connecting sleeve are interconnected, and the coating roller and the injection groove are fitted with fluff at equal intervals on their exteriors.

[0012] Compared with existing convenient tube-type ointment application devices, this utility model has the following advantages: 1. This easy-to-use tubular ointment application device uses an inner roller sleeved inside a coating roller. The coating roller and the inner roller are positioned by a mounting sleeve. Rotating the second fastening bolt limits the position of the inner roller inside the spray head. Rotating the coating roller causes the ointment to be conveyed into the filling tank. As the coating roller rotates, it moves the filling tank to the outside of the baffle. The ointment is blocked by the baffle, and the ointment collected inside the filling tank is output to the outside. The coating roller and the filling tank apply the ointment to the wound, improving the uniformity of the ointment application.

[0013] 2. This easy-to-use tubular ointment application device has a piston installed on the inner side of the pressure plate via a spring. When the screw is rotated, the screw pushes the pressure plate to move inward, while the piston applies pressure to the ointment. The pressure pushes the ointment to be delivered into the interior of the connecting sleeve, and the ointment is extruded through the connecting sleeve, ensuring sufficient ointment extrusion. That is, the ointment can be automatically extruded, improving the efficiency of ointment application. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A convenient tube-type ointment application device includes an ointment tube 1, with a nut 2 threaded onto the lower end of the ointment tube 1. The nut 2 is threaded onto the outside of the ointment tube 1 to ensure stability when the nut 2 is spliced ​​on the outside of the ointment tube 1. A screw 3 is threaded onto the inside of the nut 2, and a pressure plate 4 is movably sleeved on the inside of the screw 3. Rotating the screw 3 pushes the pressure plate 4 inward, thus applying pressure to the ointment and ensuring that the ointment is extruded. A connecting sleeve 7 is threaded onto the end of the ointment tube 1, and a spray head 8 is fixedly connected to the end of the connecting sleeve 7. A coating roller 9 and an inner roller 11 are installed inside the spray head 8 through a limiting clamp. The inner roller 11 remains stationary, while the coating roller 9 rolls, causing the ointment to be applied to the outside of the skin. Injection grooves 10 are fixedly connected at equal intervals to the outside of the coating roller 9, and a mounting plate 15 is fixedly connected to one side of the inner roller 11.

[0018] Please see Figure 2 The inside of the ointment tube 1 is filled with ointment, and the pressure plate 4 is sleeved inside the ointment tube 1. Since the inside of the ointment tube 1 is filled with ointment and the pressure plate 4 is located inside the ointment tube 1, rotating the screw 3 pushes the pressure plate 4 to apply pressure inward, that is, pushes the ointment to move inward, and then pushes the ointment to contact and apply it to the wound.

[0019] Please see Figure 2 A piston 6 is installed on the inner side of the pressure plate 4 via a spring 5. The piston 6 is in contact with the ointment. The piston 6 is installed on the inner side of the pressure plate 4 via a spring 5. The piston 6 applies elastic potential energy under the elastic action of the spring 5, that is, the ointment continuously applies pressure. When the coating roller 9 rotates, the coating roller 9 drives the ointment to contact and the coating roller 9 drives the ointment to apply the ointment to the wound.

[0020] Please see Figure 5 A baffle 12 is fixedly connected to the outside of the inner roller 11. The baffle 12 is attached to the inside of the injection trough 10. The baffle 12 is located inside the coating roller 9. When the coating roller 9 rolls, it moves the injection trough 10 to the inside of the spray head 8, and the ointment is filled into the inside of the injection trough 10. At the same time, the coating roller 9 moves the injection trough 10 to the outside of the baffle 12. The baffle 12 pushes the injection trough 10 to the outside and causes the ointment to protrude outward. The ointment can be evenly applied to the skin, ensuring the efficiency of ointment application.

[0021] Please see Figure 4 The limiting sleeve includes a mounting sleeve 13. One side of the coating roller 9 and the inner roller 11 is fitted inside the mounting sleeve 13. The mounting sleeve 13 is fitted laterally inside the spray head 8. A first fastening bolt 14 is installed inside the mounting sleeve 13. The first fastening bolt 14 passes through the mounting sleeve 13 and is threaded inside the spray head 8. The mounting sleeve 13 is installed on the side of the coating roller 9 and the inner roller 11. The two sets of mounting sleeves 13 sequentially limit the position of the coating roller 9 and the inner roller 11. After the mounting sleeve 13 is snapped into the inside of the spray head 8, the first fastening bolt 14 is installed inside the mounting sleeve 13. The first fastening bolt 14 limits the position of the mounting sleeve 13 inside the spray head 8, ensuring that the coating roller 9 and the inner roller 11 maintain stability when spliced ​​in the position inside the spray head 8.

[0022] Please see Figure 4 The mounting plate 15 is equipped with a second fastening bolt 16, which passes through the mounting plate 15 and is in contact with the outside of the mounting sleeve 13. The mounting plate 15 is installed on the side of the inner roller 11 and is located outside the mounting sleeve 13. When the second fastening bolt 16 is rotated, the second fastening bolt 16 drives the mounting plate 15 to be positioned outside the mounting sleeve 13, thus ensuring that the inner roller 11 is positioned inside the spray head 8.

[0023] Please see Figure 5 The ointment cylinder 1 and the connecting sleeve 7 are interconnected. The coating roller 9 and the injection groove 10 are equipped with equally spaced fibers on their exteriors. The ointment cylinder 1 and the connecting sleeve 7 are interconnected. After the ointment is conveyed, it comes into contact with the exterior of the coating roller 9. At the same time, the injection groove 10 installed on the exterior of the coating roller 9 drives the ointment to be conveyed. After the coating roller 9 and the injection groove 10 come into contact with the skin, the coating roller 9 and the injection groove 10 drive the ointment to be applied to the exterior of the skin. The fibers installed on the exterior of the coating roller 9 and the injection groove 10 improve comfort when they come into contact with the skin and avoid friction damage to the skin during the application of the medicine.

[0024] Working principle: During use, the ointment is placed inside the ointment cartridge 1. The pressure plate 4 drives the spring 5 and piston 6 to be installed at the rear end of the ointment cartridge 1. At the same time, the nut 2 is threaded onto the outside of the ointment cartridge 1, and the connecting sleeve 7 is threaded onto the front end of the ointment cartridge 1. Rotating the screw 3 pushes the pressure plate 4 to move inward, and the spring 5 applies elastic pressure to the piston 6. Simultaneously, the ointment moves to the inside of the spray head 8 and contacts the outside of the coating roller 9. The ointment applies pressure to the injection groove 10, causing the injection groove 10 to indent inward. After the coating roller 9 contacts the skin, it rolls. The injection tank 10 is moved to the wound, and the injection tank 10 evenly coats the outside of the wound with ointment, avoiding uneven ointment precipitation and uneven coating. When the coating roller 9 and the inner roller 11 are installed and used, the mounting sleeve 13 is laterally snapped into the inside of the spray head 8. The first fastening bolt 14 is rotated to improve the stability of the mounting sleeve 13 when it is spliced ​​outside the spray head 8. The second fastening bolt 16 is rotated, and the second fastening bolt 16 drives the mounting plate 15 to be positioned on the side of the mounting sleeve 13, ensuring that the coating roller 9 is easy to install and remove inside the spray head 8.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
