Figure 4 yes Figure 2 A magnified view of the local structure at B.

[0024] The utility model provides a radiodermatitis plaster applicator: comprising an injection shell 101, a drug storage tube 102, an applicator head 103, a piston 104, a push rod 105 and a driving mechanism, wherein the driving mechanism comprises a controller 106 and a driving assembly 107, wherein the push rod 105 comprises a rotating ring 108 and a threaded rod 109, and the driving assembly 107 comprises a storage battery 110, a servo motor 111 and an output gear 112. The above-mentioned solution solves the problem that the plaster applicator in the prior art needs to apply the plaster to the patient's body by using the applicator head 103 while manually pushing the push rod during actual use, and the operation is not convenient. It can be understood that the above-mentioned solution can be used in the structure of the plaster applicator for treating radiodermatitis.

[0025] According to this specific embodiment, a mounting protrusion 113 is provided at the end of the injection shell 101, and the applicator head 103 is installed at the mounting protrusion 113. A cover plate 114 is clamped on the injection shell 101. The drug storage tube 102 is placed inside the injection shell 101, and a drug outlet 115 is provided at one end of the drug storage tube 102. A diaphragm 116 is provided at the other end of the drug storage tube 102, and the drug outlet 115 is located inside the mounting protrusion 113. The piston 104 is provided inside the injection shell 101, and a spike 117 is provided at one end of the piston 104 close to the drug storage tube 102, and the push rod 105 is provided at one end of the piston 104 away from the drug storage tube 102. The cover plate 114 is removed, and the drug storage tube 102 filled with the plaster is placed inside the injection shell 101 so that the drug outlet 115 is located inside the mounting protrusion 113. After being inside the mounting protrusion 113, the cover plate 114 is put on, and the piston 104 is pushed by the push rod 105. Since the piston 104 is provided with the spike 117, after the spike 117 passes through the diaphragm 116, the piston 104 slides inside the drug storage tube 102, thereby delivering the plaster in the drug storage tube 102 to the application head 103 through the drug outlet 115, so that the plaster is applied to the patient's area through the application head 103, and the application head 103 is made of flexible material, thereby reducing the pain caused to the patient when the application head 103 is used to apply the dermatitis. At the same time, since the application head 103 is installed on the mounting protrusion 113 in a detachable manner, medical staff can complete the installation of the application head 103 of corresponding specifications according to the size of the dermatitis, which is more practical.

[0026] Among them, the end of the injection shell 101 away from the mounting protrusion 113 is rotatably connected to the rotating ring 108, the internal thread of the rotating ring 108 is connected to the threaded rod 109, and the end of the threaded rod 109 located inside the injection shell 101 is provided with a mounting plate 118, and the mounting plate 118 is connected to the piston 104. The end of the injection shell 101 away from the mounting protrusion 113 is also provided with the driving component 107, and the controller 106 is provided on the outer wall of the injection shell 101. The controller 106 is communicatively connected with the driving component 107. The outside of the rotating ring 108 is provided with a transmission gear 119, and the output end of the driving component 107 is mechanically transmitted with the transmission gear 119. When the application head 103 is used to apply fluid to the patient's area, During application, the controller 106 controls the operation of the driving component 107. Since the output end of the driving component 107 is mechanically transmitted with the transmission gear 119, the rotating ring 108 is driven to rotate at the end of the injection shell 101. Since the internal thread of the rotating ring 108 is connected with the threaded rod 109, the threaded rod 109 is screwed into the rotating ring 108, thereby driving the piston 104 to screw into the injection shell 101. The moving piston 104 is used to transport the plaster in the medicine storage tube 102 to the application head 103. With the above structure, when the application head 103 is used to apply to the patient's area, the plaster can be transported without the user manually pushing the push rod 105, and the operation is more convenient.

[0027] Secondly, the battery 110 and the servo motor 111 are both installed at one end of the injection housing 101 away from the mounting protrusion 113. The battery 110 is electrically connected to the servo motor 111. The output end of the servo motor 111 is provided with the output gear 112. The output gear 112 is meshed with the transmission gear 119. The servo motor 111 is powered by the battery 110, and the servo motor 111 is started to drive the output gear 112 to rotate. Since the output gear 112 is meshed with the transmission gear 119, the rotating ring 108 is driven to rotate at the end of the injection housing 101.

[0028] At the same time, an opening 120 is provided on the side wall of the injection shell 101, and a card slot 121 is provided on both sides of the opening 120. A card block 122 is provided on both sides of the cover plate 114, and the card block 122 is adapted to the card slot 121. Through the setting of the card slot 121 and the card block 122, the cover plate 114 is clamped at the opening 120 of the injection shell 101.

[0029] In addition, both sides of the exterior of the cover plate 114 are provided with anti-slip grooves 123 , and the provision of the anti-slip grooves 123 makes it more convenient to disassemble and assemble the cover plate 114 .

[0030] When using the radioactive dermatitis plaster applicator of the present embodiment, the cover plate 114 is removed, the drug storage tube 102 containing the plaster is placed inside the injection shell 101 so that the drug outlet 115 is located inside the mounting protrusion 113, and then the cover plate 114 is covered, and the piston 104 is pushed by the push rod 105. Since the piston 104 is provided with the spike 117, after the spike 117 passes through the diaphragm 116, the piston 104 slides inside the drug storage tube 102, so that the plaster in the drug storage tube 102 is transported to the application head 103 through the drug outlet 115, so that the plaster is applied to the patient's area through the application head 103, and when the application head 103 is used to apply the plaster to the patient's area, The controller 106 controls the operation of the driving component 107. Since the output end of the driving component 107 is mechanically transmitted with the transmission gear 119, the rotating ring 108 is driven to rotate at the end of the injection shell 101. Since the internal thread of the rotating ring 108 is connected with the threaded rod 109, the threaded rod 109 is screwed into the inside of the rotating ring 108, thereby driving the piston 104 to screw into the inside of the injection shell 101. The moving piston 104 is used to transport the plaster in the medicine storage tube 102 to the application head 103. With the above structure, when the application head 103 is used to apply the plaster to the patient's area, the user does not need to manually push the push rod 105 to complete the delivery of the plaster, and the operation is more convenient.
