Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicles (UAVs), and more specifically to a back-mounted medication delivery device. Background Technology

[0002] When the back is injured or has a skin condition, medication must be applied to the affected area periodically to promote faster healing. Because the back area is relatively isolated and not easily visible, applying medication is often difficult and requires assistance. As the frequency of application increases, this inconvenience to others also increases. Without help, it is difficult to accurately apply medication to the wound, especially over large areas. Inaccurate application not only wastes medication but also delays recovery. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a back medication application device that allows patients to easily apply medication to their backs themselves.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a back-mounted medication application device, comprising:

[0005] The bracket includes a support frame and a connecting plate. There are two support frames, which are vertically arranged opposite each other at intervals. The two ends of the connecting plate are connected between the two support frames and can slide up and down along the support frames.

[0006] A movable plate has a horizontally extending mounting groove that runs from front to back. The upper and lower sides of the connecting plate have a first sliding groove and a second sliding groove that communicate with the mounting groove. The movable plate is located in the mounting groove, and both ends of the movable plate are slidably engaged in the first sliding groove and the second sliding groove, respectively.

[0007] The medication application mechanism includes a medication application tray, which is disposed on the movable plate and located on the side facing the back of the human body. The end face of the medication application tray can apply medication to the back of the human body.

[0008] A driving mechanism, disposed on the movable plate, is used to drive the movable plate to slide back and forth along the mounting groove; and

[0009] A plane mirror assembly is installed on one side of the support, allowing the patient to observe their back during medication application.

[0010] Furthermore, the driving mechanism includes a mounting plate, a bidirectional rotary power source, a rotating wheel, and a driven wheel. The mounting plate covers the upper surface of the connecting plate. The bidirectional rotary power source is mounted on the mounting plate and can rotate bidirectionally. The rotational power shaft of the bidirectional rotary power source extends into the first slide groove. The rotating wheel is mounted on the rotational power shaft of the bidirectional rotary power source and abuts against one of the inner sidewalls of the first slide groove. The driven wheel is rotatably mounted on the mounting plate and abuts against the other inner sidewall of the first slide groove. The upper end of the moving plate passes through the first slide groove and is connected to the mounting plate.

[0011] Furthermore, the driving mechanism also includes a self-rotating drive assembly, which includes a transmission shaft, a first bevel gear, and a second bevel gear. The transmission shaft is coaxially disposed on the rotating wheel, the first bevel gear is sleeved and fixed on the transmission shaft, the medicine application disc is rotatably connected to the connecting plate, and the top end of the medicine application disc passes through the connecting plate. The second bevel gear is coaxially disposed on the top end face of the medicine application disc and meshes with the first bevel gear.

[0012] Furthermore, the medication application mechanism also includes a medication squeezing component. The medication application disc is a hollow disc with a medication inlet on its side wall and a medication outlet facing the back of the human body. The medication squeezing component is located on the top of the medication application disc and can simultaneously squeeze the medication in the medication application disc from the medication outlet during the movement of the medication application disc.

[0013] Furthermore, the extrusion assembly includes an eccentric wheel, a push rod, a first elastic element, and a delivery component. The delivery component is connected to the inlet and can deliver medicine from the inlet into the coating tray. The push rod is slidably and sealingly disposed within the coating tray via the first elastic element. The eccentric wheel is disposed on the drive shaft, and the outer wall of the eccentric wheel can slidably abut against the top surface of the push rod. When the small end of the eccentric wheel abuts against the push rod, the bottom surface of the push rod is located above the inlet. When the large end of the eccentric wheel abuts against the push rod, the bottom surface of the push rod is located below the inlet.

[0014] Furthermore, the drug delivery component includes a side cylinder, a second elastic element, and a push plate. The top end of the side cylinder is connected to the drug coating tray, and the bottom end of the side cylinder is closed. The push plate is sealed and slidably disposed inside the side cylinder and is connected to the bottom end face of the side cylinder through the second elastic element. A drug delivery port communicating with the inner cavity of the side cylinder is provided on the side wall of the side cylinder near the drug coating tray.

[0015] Furthermore, the connecting plate is provided with a horizontally extending extension rod.

[0016] Furthermore, the plane mirror assembly includes a first plane mirror, a second plane mirror, and a third plane mirror. The first plane mirror is located parallel to the rear of the bracket, the third plane mirror is located parallel to the front of the bracket, and the second plane mirror is located on the side of the bracket.

[0017] The beneficial effects of this invention are:

[0018] When using the above-mentioned back medication device, first apply the ointment to the end face of the application plate. Then, observe the plane mirror group and adjust the height of the connecting plate according to the required application height on the back. Next, face the back to the application plate and start the drive mechanism. The drive mechanism drives the application mechanism to move back and forth laterally to apply the medication to the back wound. After completing the application at the same height, the patient manually adjusts the height of the moving plate to apply the medication to the next height. This process is repeated until all the medication has been applied.

[0019] With this device, users can apply medication to their backs independently and accurately without the need for assistance from others. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 The present invention provides a back medication application device, including a support 100, a movable plate 200, a medication application mechanism 300, a drive mechanism 400, and a plane mirror assembly 500.

[0031] Specifically, the bracket 100 includes a support frame 110 and a connecting plate 120. There are two support frames 110, which are vertically spaced apart. The two ends of the connecting plate 120 are connected between the two support frames 110 and can slide up and down along the support frames 110. The movable plate 200 has a horizontally extending mounting groove 121, and the upper and lower sides of the connecting plate 120 have a first sliding groove and a second sliding groove communicating with the mounting groove 121, respectively. The movable plate 200 is located in the mounting groove 121, and the two ends of the movable plate 200 are slidably engaged in the first sliding groove and the second sliding groove, respectively.

[0032] The medication application mechanism 300 includes an application tray 310. The application tray 310 is mounted on a movable plate 200 and located on the side facing the back of the patient. The end face of the application tray 310 allows medication to be applied to the back of the patient. A drive mechanism 400 is mounted on the movable plate 200 and drives the movable plate 200 to slide back and forth along the mounting groove 121. A plane mirror assembly 500 is mounted on one side of the support 100, allowing the patient to observe their back during medication application.

[0033] When using the ointment, first apply it to the end face of the application plate 310. Then, observe the plane mirror group 500 and adjust the height of the connecting plate 120 according to the height of the back to which the ointment needs to be applied. Then, face the back towards the application plate 310 and start the drive mechanism 400. The drive mechanism 400 drives the application mechanism 300 to move back and forth laterally to apply the ointment to the wound on the back. After completing the application at the same height, the patient manually adjusts the height of the moving plate 200 to apply the ointment to the next height. Repeat this process until all the ointment has been applied.

[0034] With this device, users can apply medication to their backs independently and accurately without the need for assistance from others.

[0035] In this embodiment, the plane mirror assembly 500 includes a first plane mirror 510, a second plane mirror 520, and a third plane mirror 530. The first plane mirror 510 is located parallel to the rear of the support 100, the third plane mirror 530 is located parallel to the front of the support 100, and the second plane mirror 520 is located on the side of the support 100. Through these three plane mirrors, the patient can accurately observe their back and more accurately apply medication to the back.

[0036] In this embodiment, the drive mechanism 400 includes a mounting plate 410, a bidirectional rotary power source 420, a rotating wheel 430, and a driven wheel 440. The mounting plate 410 covers the upper surface of the connecting plate 120. The bidirectional rotary power source 420 is mounted on the mounting plate 410 and can rotate bidirectionally. The rotational shaft of the bidirectional rotary power source 420 extends into the first slide groove. The rotating wheel 430 is mounted on the rotational shaft of the bidirectional rotary power source 420 and abuts against one of the inner walls of the first slide groove. The driven wheel 440 is rotatably mounted on the mounting plate 410 and abuts against the other inner wall of the first slide groove. The upper end of the movable plate 200 passes through the first slide groove and is connected to the mounting plate 410.

[0037] When the applicator disk 310 needs to be driven laterally, simply activating the bidirectional rotary power source 420 will rotate the rotating wheel 430. Through the friction between the rotating wheel 430 and the driven wheel 440 and the inner wall of the first chute, the entire moving plate 200 can be moved forward or backward. Of course, in other embodiments, the drive mechanism 400 can also be a telescopic mechanism capable of extending and retracting along the horizontal direction. In specific implementations, the bidirectional rotary power source 420 can be a rotary motor commonly used in the prior art.

[0038] In a preferred embodiment, the drive mechanism 400 further includes a rotation drive assembly 450. The rotation drive assembly 450 includes a drive shaft 451, a first bevel gear 452, and a second bevel gear 453. The drive shaft 451 is coaxially mounted on the rotating wheel 430, the first bevel gear 452 is fixedly sleeved on the drive shaft 451, the applicator disk 310 is rotatably connected to the connecting plate 120, and the top end of the applicator disk 310 passes through the connecting plate 120. The second bevel gear 453 is coaxially mounted on the top surface of the applicator disk 310 and meshes with the first bevel gear 452.

[0039] When the bidirectional rotating power source 420 rotates, it can drive the transmission shaft 451 to rotate. Through the first bevel gear 452 and the second bevel gear 453, it can drive the application disk 310 to rotate, so that the application disk 310 rotates during the lateral movement, making the drug application more uniform and thus improving the application quality.

[0040] In a more preferred embodiment, the medication application mechanism 300 further includes a medication extrusion assembly 320. The application disk 310 is a hollow disk. A medication inlet 312 is provided on the side wall of the application disk 310. A medication outlet 311 is provided on the application disk 310 facing the back of the human body. The medication extrusion assembly 320 is disposed on the top of the application disk 310 and can extrude the medication in the application disk 310 from the medication outlet 311.

[0041] When in use, the medicine can be pre-stored in the application tray 310 through the medicine inlet 312. During the movement of the application tray 310, the medicine extrusion component 320 simultaneously extrudes the ointment.

[0042] Specifically, the extrusion assembly 320 includes an eccentric wheel 321, a push rod 322, a first elastic element 323, and a delivery component 324. The delivery component 324 is connected to the inlet 312 and can deliver medication from the inlet 312 into the application tray 310. The push rod 322 is slidably and sealingly disposed within the application tray 310 via the first elastic element 323. The eccentric wheel 321 is disposed on a rotating shaft. The outer wall of the eccentric wheel 321 can slidably abut against the top surface of the push rod 322, and when the small end of the eccentric wheel 321 abuts against the push rod 322, the bottom surface of the push rod 322 is located above the inlet 312; when the large end of the eccentric wheel 321 abuts against the push rod 322, the bottom surface of the push rod 322 is located below the inlet 312.

[0043] When the bidirectional rotary power source 420 rotates, it can drive the eccentric wheel 321 to rotate. When the large end of the eccentric wheel 321 contacts the push rod 322, the push rod 322 can be pressed down to squeeze the ointment in the application tray 310 out of the dispensing hole 311.

[0044] In other embodiments, the extrusion assembly 320 can be used in other ways, such as by providing a telescopic mechanism on the top of the application disc 310 to extrude the drug. In a specific implementation, in order to extrude all the drug, the push rod 322 can be positioned at its lowest point so that it is in contact with the inner bottom surface of the application disc 310.

[0045] In this embodiment, the drug delivery component 324 includes a side cylinder 3241, a second elastic element 3242, and a push plate 3243. The top end of the side cylinder 3241 is connected to the application tray 310, and the bottom end of the side cylinder 3241 is closed. The push plate 3243 is sealed and slidably disposed inside the side cylinder 3241 and is connected to the bottom end face of the side cylinder 3241 through the second elastic element 3242. A drug delivery port 3244 communicating with the inner cavity of the side cylinder 3241 is provided on the side wall of the side cylinder 3241 near the application tray 310.

[0046] In use, first manually press the push rod 322 down to the bottom to block the inlet 312. Then, inject the ointment into the side cylinder 3241 through the filling port 3244. As the ointment is added, it pushes the push plate 3243 backward, and the second elastic element 3242 contracts until the side cylinder 3241 is full. When applying the ointment, each time the push rod 322 rises, under the restoring force of the second elastic element 3242, the push plate 3243 adds ointment to the application tray 310 through the inlet 312. Each time the push rod 322 falls, it blocks the inlet 312 and presses down the ointment, allowing the ointment to be squeezed out of the outlet once.

[0047] This method can create a synchronous automatic dosing system, further improving ease of use.

[0048] In this embodiment, to facilitate the movement of the connecting plate 120, a horizontally extending extension rod 130 is provided on the connecting plate 120. The user can move the connecting plate 120 up and down by operating the extension rod 130, further improving the ease of operation.

[0049] How to use the above-mentioned back medication device:

[0050] In use, first manually press the push rod 322 down to the bottom to block the inlet 312. Then, inject the ointment into the side cylinder 3241 through the filling port 3244. As the ointment is added, it pushes the push plate 3243 backward, and the second elastic element 3242 contracts until the side cylinder 3241 is full.

[0051] Subsequently, the patient, with their back to the application tray 310, observes the third plane mirror 530, holds the extension rod 130, and adjusts the height of the connecting plate 120 so that the application tray 310 is positioned at the top of the wound requiring application. Then, the bidirectional rotating power source 420 is activated. During the forward and reverse rotation of the bidirectional rotating power source 420, the moving plate 200 is driven to move the application tray 310 forward or backward to apply the ointment. After completing the application at one height, the patient adjusts the moving plate 200 to move it down to apply the ointment at the next height, repeating this process until all medication is applied.

[0052] During the movement of the moving plate 200, the bidirectional rotary power source 420 also drives the application plate 310 to rotate, which can make the medicine more evenly applied. In addition, the bidirectional rotary power source 420 also drives the push rod 322 to move up and down through the eccentric wheel 321. When applying medicine, each time the push rod 322 rises, under the restoring force of the second elastic element 3242, the push plate 3243 adds medicine into the application plate 310 through the medicine inlet 312. Each time the push rod 322 falls, it blocks the medicine inlet 312 and presses down the ointment, which squeezes the ointment out of the medicine outlet. This forms a synchronous automatic medicine addition method. At the same time, the medicine delivery component 324 can automatically deliver medicine, further improving the ease of use.

[0053] Using the above-mentioned device, not only can the medicine be applied accurately, but the medicine can also be added automatically, further improving convenience.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
