[0024] Reference Figures 1-6 This utility model provides a precise drug delivery device for topical skin applications, including a dispensing cylinder 1. A dispensing rack 11 is provided on one side of the dispensing cylinder 1, and a squeezing component 2 is mounted on the other side of the dispensing cylinder 1. The squeezing component 2 is slidably installed inside the dispensing cylinder 1. A fixing plate 13 is provided inside the dispensing cylinder 1 near the dispensing rack 11, forming two separate chambers inside the dispensing cylinder 1. A placement hole 12 is provided inside the dispensing rack 11. A discharge rack 3 is slidably installed in the placement hole 12; the discharge rack 3 is provided with two symmetrical connecting columns 31, both of which are hollow and slidably located on the fixing plate 13, allowing the medicine in the discharge cylinder 1 to move into the discharge rack 3; the discharge rack 3 is provided with a reset member 4, which is connected to the inside of the discharge cylinder 1 inside the discharge placement rack 11, and the position of the discharge rack 3 in the discharge placement rack 11 is positioned by the reset member 4.

[0025] This application provides a drug delivery device for external application to a patient's affected skin. The device includes a dispensing cylinder 1 for holding the drug, which is divided into two chambers by a fixing plate 13. The chamber closer to the extrusion component 2 is the dispensing chamber, where the drug is located. The extrusion component 2 is slidably mounted within the dispensing cylinder 1 and its function is to extrude the drug, allowing it to move towards the fixing plate 13. The dispensing rack 3 is located within the drug placement chamber of the dispensing cylinder 1 via two connecting posts 31 passing through the fixing plate 13. The drug in the dispensing cylinder 1 can be moved to the dispensing rack 3 via the connecting posts 31, and then dispensing to the patient's affected skin. This application primarily focuses on the dispensing rack 3 being slidably mounted within a dispensing rack 11, and the reset component 4 mounted on the dispensing rack 3. Each time the dispensing rack 3 needs to dispense material, it needs to be pressed down in a certain position. The dispensing rack 3 will then move towards the fixing plate 13 in the placement hole 12. During this movement, the dispensing rack 3 will drive the two connecting columns 31 to move within the fixing plate 13. Each time the dispensing rack 3 is pressed down and moves towards the fixing plate 13, the two connecting columns 31 will pass through the fixing plate 13 and be located in the drug placement chamber. When the dispensing rack 3 is not pressed down, the two connecting columns 31 will block the holes in the fixing plate 13, so the drug in the drug placement chamber has no room to move. At this time, even if the extrusion component 2 extrudes material in the dispensing cylinder 1, it will not be able to move due to air resistance. This method can increase the protection function of the drug dispenser and effectively prevent the problem of excessive loss of internal drug when the drug dispenser is accidentally pressed.

[0026] Preferably, the feeding cylinder 1 is provided with an assembly groove 14 and a feeding mating groove 15 on the side near the extrusion component 2. The assembly groove 14 is used for the extrusion component 2 to be slidably installed in the feeding cylinder 1, and the feeding mating groove 15 is used for the drug to enter the feeding cylinder 1 through the extrusion component 2.

[0027] Preferably, the extrusion component 2 includes an extrusion plate 21, a connecting rod 22, and an extrusion rod 23. The extrusion plate 21 is located in the discharge cylinder 1. One end of the connecting rod 22 is connected to the extrusion plate 21 in the discharge cylinder 1, and the other end of the connecting rod 22 passes through the assembly groove 14 and is located outside the discharge cylinder 1. The extrusion rod 23 is disposed on the other end of the connecting rod 22.

[0028] In this application, the extrusion plate 21, the connecting rod 22 and the extrusion rod 23 are slidably installed on the discharge cylinder 1 in a mutually connected manner. The user can press the extrusion rod 23 to make the extrusion rod 23 drive the connecting rod 22 and the extrusion plate 21 to move in the discharge cylinder 1, so that the extrusion plate 21 can extrude the medicine in the discharge cylinder 1.

[0029] Preferably, the extrusion plate 21 is provided with a feeding cylinder 24 and a sealing plate 25.

[0030] In this application, the feeding cylinder 24 is used for feeding the drug. The user can pour the drug into the discharging cylinder 1 through the feeding cylinder 24. The feeding cylinder 24 can also be used to remove the air in the discharging cylinder 1. When the extrusion plate 21 is in the discharging cylinder 1, since there is a certain space inside the discharging cylinder 1, and the drug may not fill the space, each time the extrusion plate 21 moves in the discharging cylinder 1, the excess space can be removed through the feeding cylinder 24 first, and then the feeding cylinder 24 can be closed by the sealing plate 25.

[0031] Preferably, each of the connecting posts 31 has a plurality of openings 311 around the side wall near the fixing plate 13, and the plurality of openings 311 are used for the drug to enter the connecting post 31.

[0032] In this application, the connecting column 31 is a key connecting component for drug flow. The connecting column 31 itself is a hollow column, with one end open and connected to the discharge rack 3, and the other end closed and sliding in the fixed plate 13. When the discharge rack 3 is not squeezed in the placement hole 12 and is in its original position, the connecting column 31 will be in the fixed plate 13. At this time, the multiple openings 311 provided on the connecting column 31 will be located on one side of the discharge rack 3 in the discharge cylinder 1. When the discharge rack 3 is squeezed in the placement hole 12 and moves towards the fixed plate 13, the two connecting columns 31 will also move towards the fixed plate 13 at the same time. At this time, the multiple openings 311 provided on the connecting column 31 will be located on the side of the discharge cylinder 1 containing the drug. When the squeezing plate 21 moves in the discharge cylinder 1 to squeeze, the drug in the discharge cylinder 1 will enter the connecting column 31 through the multiple openings 311.
