Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a gel application device for wound skin repair. Background Technology

[0002] During the treatment of dermatological patients, a special application device is required to apply the medication to meet their treatment needs. In the current technology, when applying medication to dermatological patients, medical staff usually squeeze the ointment onto the affected skin and then spread the ointment evenly on the affected area.

[0003] To address the aforementioned issues, a medication application device has been commercially available. This device includes a medication block, a medication application chamber within the medication block, a push rod located within a sterilization chamber, a dispensing port on the medication application chamber, and a latch on the dispensing port. In use, the latch is opened, and the medication to be applied is squeezed into the medication application chamber. By pushing the push rod within the medication application chamber, the medication is dispensed through the dispensing port to the affected area, thus achieving medication application.

[0004] The above-mentioned device has the following problems in actual use: When applying the ointment to the affected area, the push rod is moved by human force, which cannot guarantee that the push rod can squeeze the ointment in the application chamber at a uniform speed. This results in uneven ointment extrusion. Excessive ointment extrusion will lead to waste, while insufficient ointment extrusion will not guarantee the treatment effect on the affected area and will not be applied well to the affected area, resulting in poor application effect. Summary of the Invention

[0005] This invention provides a gel application device for wound skin repair, which solves the problem that existing drug application devices cannot evenly apply the gel to the affected area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a gel application device for wound skin repair, comprising a grip and an application mechanism; the application mechanism includes a medicine cartridge and application components symmetrically arranged along the width direction of the medicine cartridge; the medicine cartridge is fixedly connected to the grip; the application components include a side shaft, a side block, a hollow disc, a cotton swab, a hollow cylinder, a medicine box, a medicine dispensing tube, a piston cylinder, a piston block, a medicine dispensing hole on the medicine box, a drive unit for driving the side shaft to rotate, and a power unit for driving the piston block to perform vertical reciprocating motion; the side shaft is rotatably connected to the medicine cartridge; both ends of the side block are fixedly connected to the side shaft and the hollow disc respectively; the cotton swab is detachably connected to the hollow disc; both ends of the hollow cylinder are fixedly connected to the medicine cartridge and the medicine box respectively; both ends of the medicine dispensing tube are connected to the medicine cartridge and the medicine box respectively; the piston cylinder is fixedly connected to the medicine box; the piston block is slidably connected to the piston cylinder; an inlet pipe and an outlet pipe are connected to the piston cylinder; both the inlet pipe and the outlet pipe are connected to the medicine dispensing tube; the medicine dispensing hole faces the cotton swab.

[0007] The principles and advantages of this scheme are: The gel is placed inside the medication cartridge. Through the interaction of the piston block and piston cylinder, the gel flows along the medication tube and cartridge, finally entering through the medication port and onto the cotton swab. While the gel is applied to the cotton swab, the swab can rotate, allowing the gel to be evenly distributed across any part of the swab, and the swab to be evenly spread over the affected area. Therefore, this movement ensures the gel is fully and completely applied to the affected area, thus improving the efficiency and quality of the gel's action.

[0008] The piston block and piston cylinder are designed to increase the flow rate of the gel and also to ensure that the gel can be applied fully and evenly to the cotton, thereby enhancing the gel's effect.

[0009] The removable design of the cotton pad is intended to facilitate replacement and thus reduce the probability of cross-infection.

[0010] Furthermore, the application assembly also includes a stirring unit; the stirring unit includes a fixed block, a side block, a stirring block, a through hole on the dispensing tube, a side hole on the hollow cylinder, and a motion unit for driving the side block to reciprocate along the length of the fixed block; the fixed block is fixedly connected to the hollow cylinder; the side block is slidably connected to the fixed block; the stirring block is slidably connected to the through hole, and the stirring block is fixedly connected to the side block.

[0011] The mixing block is designed to make the gel more dense and creamy, reducing the likelihood of lumps and increasing its flow rate. This faster mixing ensures the gel is applied more completely to the cotton pad, thus enhancing its healing effect on the affected area.

[0012] Furthermore, the application assembly also includes a flow guide; the flow guide includes a flow guide shaft, a flow guide vane, and a power unit for driving the flow guide shaft to rotate; the flow guide shaft is rotatably connected to the dispensing tube; and the flow guide vane is fixedly connected to the flow guide shaft.

[0013] The guide vanes are designed to further increase the flow rate of the gel, thereby allowing the gel to act more fully on the cotton pad and ensuring the quality of the application to the affected area.

[0014] Furthermore, the stirring section also includes a linkage unit; the linkage unit includes a linkage block, a long rod, a bottom rod, several push blocks, and a linkage hole opened on the medicine dispensing box; the linkage block is fixedly connected to the side block; the two ends of the long rod are fixedly connected to the linkage block and the bottom rod respectively, and the long rod can reciprocate within the linkage hole; several push blocks are fixedly connected to the bottom rod, and the push blocks are in contact with the medicine dispensing hole.

[0015] As the pusher reciprocates along the length of the dispensing hole, it effectively pushes the gel into the hole while reducing the likelihood of clogging. Therefore, the pusher promotes efficient and thorough application of the gel to the coating material, thus enhancing the dispensing effect.

[0016] Furthermore, the application mechanism also includes a dispensing box and a dispensing section symmetrically arranged along the width of the dispensing box; both ends of the dispensing box are fixedly connected to two hollow cylinders respectively; the dispensing section includes a dispensing tube, a nozzle, a connecting pipe, and a bottom hole opened on the dispensing tube; the dispensing tube is fixedly connected to the bottom hole; the nozzle is connected to the dispensing tube; both ends of the connecting pipe are connected to the lower dispensing box and the dispensing tube respectively; the connecting pipe is located on the movement trajectory of the pusher block.

[0017] The inclusion of a dispensing tube and a drainage tube is designed to expand the gel's effective range, allowing it to act on the affected area from different locations. This reduces the risk of the gel being blocked by the dispensing hole, ensuring that the gel can effectively act on the affected area and thus enhancing its healing effect.

[0018] Furthermore, the pusher action allows the gel to flow more fully into the dispensing tube through the tube, thus ensuring the gel flow rate within the dispensing tube.

[0019] The nozzle is designed to alter the gel's form, allowing it to act on the affected area in different fluid states, thus enriching its effects. This process enables the gel to effectively target blind spots on the affected area, further improving its efficiency and quality.

[0020] Furthermore, the dispensing unit also includes an auxiliary unit; the auxiliary unit includes an auxiliary block and an auxiliary component for driving the auxiliary block to perform vertical reciprocating motion; the auxiliary block is slidably connected to the dispensing tube and fixedly connected to the nozzle.

[0021] With the assistance of the auxiliary block, the nozzle can perform a vertical reciprocating motion. During this motion, the nozzle can apply pressure to the gaps in the affected area, moving from far to near and from near to far, thereby further reducing blind spots. This motion further enhances the gel's effectiveness, ensuring that it can more efficiently repair the affected area.

[0022] Furthermore, the side shaft extends into the drug delivery cartridge; the coating assembly also includes a stirring blade; the stirring blade is fixedly connected to the side shaft.

[0023] During the rotation of the stirring blade, the flow rate of the gel inside the cartridge increases, reducing the probability of gel coagulation and ensuring that the gel can flow fully and completely into the lower cartridge, thus improving the gel's efficiency.

[0024] Furthermore, the application mechanism also includes a rotating shaft, a gearbox, a first bevel gear, a chamber opened in the grip block, and a drive component for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the cartridge, the gearbox, and the chamber respectively; the gearbox is fixedly connected to the inner wall of the cartridge; the first bevel gear is fixedly connected to the rotating shaft; the drive unit includes a drive shaft and a second bevel gear; the drive shaft is rotatably connected to the gearbox; both ends of the drive shaft are fixedly connected to the side shaft and the second bevel gear respectively; the first bevel gear meshes with the second bevel gear.

[0025] During the rotation of the shaft, the meshing of the first and second bevel gears drives the drive shaft to rotate. During the rotation of the drive shaft, the side shaft moves synchronously.

[0026] Furthermore, the power unit includes a power shaft, a first gear, a first rack, and a power component for driving the power shaft to rotate; the power shaft is rotatably connected to the hollow cylinder; the first gear is fixedly connected to the power shaft; the first rack is slidably connected to the piston cylinder and fixedly connected to the piston block; the first rack meshes with the first gear.

[0027] During the rotation of the power shaft, the first rack can perform vertical reciprocating motion through the meshing of the first gear and the first rack. During the movement of the first rack, the piston block moves synchronously.

[0028] Furthermore, the motion unit is the second gear; the second gear is fixedly connected to the power shaft; the linkage block is the second rack; the second rack meshes with the second gear.

[0029] During the rotation of the power shaft, the second gear meshes with the second rack, enabling the second rack to reciprocate along the length of the fixed block. Attached Figure Description

[0051] The power component includes a third rack 39 and a fixing groove on the guide block 37; the third rack 39 is fixedly connected to the fixing groove and meshes with the first gear 30.

[0052] Specific implementation process: The gel is placed inside the cartridge 3, and the motor is started, which in turn drives the rotating shaft to rotate via the motor's output shaft. During the rotation of the rotating shaft, the first and second bevel gears mesh, thereby driving the drive shaft 40 to rotate. During the rotation of the drive shaft 40, the side shaft 4 rotates synchronously. During the rotation of the second cam 38, when the protrusion of the second cam 38 abuts against the guide block 37, the guide block 37 moves vertically downward, and the second spring is compressed; when the protrusion of the second cam 38 no longer abuts against the guide block 37, the guide block 37 returns to its original position under the action of the second spring, and the guide block 37 moves vertically upward. Therefore, the guide block 37 can perform vertical reciprocating motion. During the movement of the guide block 37, the third rack 39 moves synchronously.

[0053] During the movement of the third rack 39, it meshes with the first gear 30, which in turn drives the power shaft to rotate. During the rotation of the first gear 30, since the first gear 30 meshes with the first rack 12, the first rack 12 drives the piston block to perform vertical reciprocating motion.

[0054] The piston block reciprocates vertically. Through the cooperation of the piston block and the piston cylinder 11, the piston cylinder 11 causes the gel to flow along the drug delivery tube 10, the drug delivery box 9, and finally through the drug delivery hole 13 onto the cotton pad 7. During the application of the gel to the cotton pad 7, the side shaft 4 can rotate the cotton pad 7 via the side block 5. During the rotation of the cotton pad 7, the gel can be evenly applied to any position on the cotton pad 7, and the cotton pad 7 can be evenly spread on the affected area. Therefore, through the above-mentioned movement, the gel can be fully and completely applied to the affected area, thereby improving the efficiency and quality of the gel's action.

[0055] The piston block and piston cylinder 11 are designed to increase the flow rate of the gel and also to ensure that the gel can be applied fully and evenly to the coating 7, thereby enhancing the gel's effect.

[0056] The removable design of the cotton swab 7 is to facilitate its replacement, thereby reducing the probability of cross-infection.

[0057] During the rotation of the power shaft, the second rack reciprocates along the length of the fixed block 14 through the meshing of the second gear 31 and the second rack. During the movement of the second rack, the second rack drives the stirring block 16 to move synchronously through the side block 15.

[0058] The mixing block 16 is designed to make the gel more dense and smooth, reducing the probability of lumps and increasing its flow rate. Therefore, the rapid mixing ensures the gel is applied more completely to the cotton pad 7, thereby enhancing its healing effect on the affected area.

[0059] During the rotation of the drive shaft 40, the drive shaft 40 drives the worm 32 to rotate via the belt 34. During the rotation of the worm 32, due to the meshing of the worms 32, the worm wheel 33 drives the guide shaft 17 to rotate. During the rotation of the guide shaft 17, the guide vanes 18 rotate synchronously.

[0060] The guide vane 18 is designed to further increase the flow rate of the gel, thereby enabling the gel to act more fully on the cotton pad 7, thus ensuring the quality of the application of the cotton pad 7 to the affected area.

[0061] During the movement of the second rack, the second rack drives the bottom rod 21 to move synchronously via the long rod 20. During the movement of the bottom rod 21, the pusher block 22 moves synchronously. As the pusher block 22 reciprocates along the length of the dispensing hole 13, it can push the gel into the dispensing hole 13 as much as possible, and at the same time reduce the probability of the gel clogging the dispensing hole 13. Therefore, under the action of the pusher block 22, the gel can be efficiently and fully applied to the coating 7, thus enhancing the dispensing effect.

[0062] The purpose of the dispensing tube 24 and the unblocking tube 26 is to expand the range of action of the gel, enabling the gel to act on the affected area from different locations. This reduces the risk of the gel being blocked by the dispensing hole 13, ensuring that the gel can effectively act on the affected area, thus enhancing the healing effect of the gel.

[0063] Furthermore, under the pushing action of the pusher 22, the gel can flow more fully into the dispensing tube 24 through the tube 26, thereby ensuring the gel flow rate in the dispensing tube 24.

[0064] The nozzle 25 is designed to alter the gel's form, allowing it to act on the affected area in different fluid states, thus enriching its effects. Through this process, the gel can effectively target blind spots on the affected area, further improving its efficiency and quality.

[0065] During the rotation of the worm gear 32, the first cam 35 rotates synchronously. During the rotation of the first cam 35, when the protrusion of the first cam 35 abuts against the auxiliary block 27, the auxiliary block 27 moves vertically downwards, compressing the first spring; when the protrusion of the first cam 35 no longer abuts against the auxiliary block 27, the auxiliary block 27 returns to its original position under the action of the first spring, and the auxiliary block 27 moves vertically upwards. Therefore, the auxiliary block 27 can perform vertical reciprocating motion.

[0066] With the assistance of the auxiliary block 27, the nozzle 25 can perform vertical reciprocating motion. During this motion, the nozzle 25 can act on the gaps in the affected area from far to near and from near to far, thereby further reducing blind spots in the affected area. Through this motion, the effects of the gel are further enhanced, ensuring that the gel can more effectively repair the affected area.

[0067] During the rotation of the side shaft 4, the stirring blades 28 rotate synchronously. The rotation of the stirring blades 28 can accelerate the flow rate of the gel in the cartridge 3, reduce the probability of gel coagulation, and ensure that the gel can flow fully and completely into the lower cartridge 9, thereby improving the gel's efficiency.

[0068] In summary, by promoting the flow of the gel and the interaction between the gel and the cotton pad 7, the gel can be applied fully and completely to the affected area, thereby improving the efficiency and quality of the gel's action.
