[0002] For patients with skin diseases, the most common treatment method is to apply ointment to the affected area to treat the affected area. However, some contagious skin diseases, such as athlete's foot, eczema and other diseases, are easily contagious, so you need to be careful when applying ointment.

[0003] At present, the method of applying ointment to the affected part, especially for some infectious skin diseases, is that the patient will use a cotton swab to dip the ointment and apply it to the affected part, and evenly apply it to the affected part. After the application is completed, the cotton swab can be thrown away. Although this method can apply ointment to the affected part, the frequent use of cotton swabs will also increase the cost of use. Skin diseases do not get better quickly, so it is necessary to insist on applying ointment, which undoubtedly increases the cost of use. Therefore, an external drug coating device is proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0023] Reference Figure 1-Figure 4 The utility model provides a technical solution: an external drug coating device, comprising a rectangular frame 1 and a coating mechanism 3, wherein a fixing plate 2 is fixedly installed inside the rectangular frame 1, the coating mechanism 3 comprises a coating wheel 31, the coating wheel 31 is rotatably installed on the inner side of the rectangular frame 1, an extrusion plate 32 is slidably installed on the inner side of the rectangular frame 1, a circular plate 331 is installed on the outer side of the coating wheel 31, a connecting rod 33 is installed on the circular plate 331, and the connecting rod 33 is fixedly connected to the extrusion plate 32.

[0024] In a preferred embodiment, one end of the coating wheel 31 is arranged outside the rectangular frame 1, and the outer side surface of the coating wheel 31 is fixedly connected to the rotating rod 4, and one end of the rotating rod 4 is fixedly connected to the circular plate 331. In order to facilitate the control of the rolling of the coating wheel 31, a rotating rod 4 is installed on the outside of the coating wheel 31. The rotating rod 4 is rotatably installed inside the rectangular frame 1. When the rectangular frame 1 is pushed to move, the coating wheel 31 will be driven to roll, which is convenient for coating the drug.

[0025] In a preferred embodiment, the outer surface of the circular plate 331 is fixedly connected to the round rod 5, and the outer part of the round rod 5 is sleeved with a connecting block 6. The round rod 5 is slidably connected to the inside of the connecting block 6, and one end of the connecting block 6 is fixedly connected to the connecting rod 33. Under the rolling of the coating wheel 31, this device can not only evenly apply the medicine, but also control the stable up and down movement of the extrusion plate 32. Therefore, the round rod 5 is fixedly installed on the outer surface of the circular plate 331, and the round rod 5 is set to slide inside the connecting block 6 to drive the connecting rod 33 to move up and down, thereby facilitating the up and down movement of the extrusion plate 32 to meet the needs of use.

[0026] In a preferred embodiment, a through hole 7 is opened on the outer side of the rectangular frame 1, and the outer side of the extrusion plate 32 is fixedly connected to the sliding rod 8, and the sliding rod 8 is integrated with the extrusion plate 32. In order to make the extrusion plate 32 move up and down stably, the sliding rod 8 is fixedly installed on the outer surface of the extrusion plate 32. The sliding rod 8 is set to slide inside the through hole 7 to control the extrusion plate 32 to move up and down stably, so as to squeeze the ointment inside the medicine tube and apply it to the affected area of ​​the skin.

[0027] Through the above description, the squeezing plate 32 can squeeze out the ointment inside the medicine tube. For the convenience of operation, the squeezing plate 32 is set to a rectangular shape. A rectangular hole 9 is opened on the outer surface of the squeezing plate 32 and penetrates the interior of the squeezing plate 32. One end of the medicine tube is placed in the rectangular hole 9. When the squeezing plate 32 is controlled to move downward, the ointment inside the medicine tube can be squeezed out.

[0028] The device places the medicine tube inside the rectangular frame 1 for use. During use, in order to prevent the medicine tube from falling from the inside of the rectangular frame 1, a limiting mechanism 10 is installed on the extrusion plate 32. The limiting mechanism 10 includes a limiting plate 101, a spring 102 and a buffer block 103. A circular groove is opened on one side of the extrusion plate 32, and the inner bottom of the circular groove is fixedly connected to the spring 102. One end of the spring 102 is fixedly connected to the limiting plate 101. Two limiting plates 101 are provided, and are respectively arranged on the front and rear sides of the extrusion plate 32. The buffer block 103 is fixedly installed on the inner side of the limiting plate 101.

[0029] During operation, the coating wheel 31 rotates to drive the extrusion plate 32 to move, thereby extruding the medicine tube. Since the limiting plate 101 is installed on the extrusion plate 32, the extrusion plate 32 will also drive the limiting plate 101 to move downward when it moves downward, which will limit the medicine tube and effectively prevent the medicine tube from falling from the inside of the rectangular frame 1. In addition, driven by the extrusion plate 32, the limiting plate 101 can move back and forth to enhance the limiting effect on the medicine tube.

[0030] Specifically, the working process or working principle of an external drug coating device is as follows: the current method of applying ointment to the affected area, especially for some infectious skin diseases, is that the patient will use a cotton swab to dip the ointment and apply it to the affected area, and evenly apply it to the affected area. After the application is completed, the cotton swab can be thrown away. Although this method can apply ointment to the affected area, frequent use of cotton swabs will also increase the cost of use. Skin diseases do not get better quickly, so it is necessary to insist on applying ointment, which undoubtedly increases the cost of use. Therefore, this device is designed to solve this problem.

[0031] The device is used to apply external medicines on the skin, which effectively prevents the medicines from being smeared on the hands and prevents infection. When using the device, the medicine tube is placed on the inner side of the rectangular frame 1, and one end of the medicine tube is extended into the interior of the fixed plate 2, so that the medicine outlet end of the medicine tube corresponds to the position of the coating wheel 31, and then the squeezing plate 32 is moved, the squeezing plate 32 is sleeved on the outside of the medicine tube, and the squeezing plate 32 is moved to the position of the medicine inside the medicine tube. At the same time, the limiting plate 101 will also limit the outside of the medicine tube to prevent the medicine tube from falling from the inside of the rectangular frame 1.

[0032] Then place the coating wheel 31 on the affected area of ​​the skin, and then push the device to move, so that the coating wheel 31 rolls on the skin, and the rolling of the coating wheel 31 drives the connecting rod 33 to move up and down. Since the connecting rod 33 is fixedly connected to the extrusion plate 32, the extrusion plate 32 moves downward first and then upward. The downward movement of the extrusion plate 32 will squeeze the medicine inside the medicine tube and drop it onto the outer surface of the coating wheel 31. The coating wheel 31 continues to roll on the skin, so the ointment can be applied to the affected area. There is no need to apply it by hand during this process to avoid bacterial infection on the hands.

[0033] In order to save the use of medicine, the amount of medicine squeezed out by controlling the squeezing plate 32 to move downward is the amount used once. When the squeezing plate 32 is controlled to move downward, the ointment will not be squeezed out, thereby avoiding waste and reducing the cost of use.

[0034] As the use of medicine in the medicine tube gradually decreases, the device sets the connecting rod 33 into two sections, one of which is set to slide inside the other end, and the connecting rods 33 at both ends are fixedly connected together by positioning pins. In subsequent use, the position of the squeezing plate 32 can be adjusted so that the squeezing plate 32 can squeeze out the ointment every time it is used to meet the needs of use.
