Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a skin medication application device. Background Technology
[0002] Skin diseases are usually treated with topical ointments. The traditional method of application is done with cotton swabs or cotton balls, which are disposable and inconvenient. Some methods use rollers for application, but this requires the roller to be kept low relative to the reservoir, which has significant limitations.
[0003] The technical solution disclosed in Chinese Patent No. CN219271930U involves movably mounting the ointment component within a cylindrical front holder, aligning the ointment with an application roller. As the roller rotates, it adheres to the ointment, allowing it to roll onto the patient's skin. This method minimizes friction between the roller and the patient's skin, preventing pain. After application, only the outer surface of the roller needs cleaning, preventing ointment waste and allowing for reuse by others. This solution overcomes the limitations of existing technologies where directly sliding the ointment onto the patient's skin causes pain and requires the ointment to be cut off to prevent bacterial transmission.
[0004] However, the device still has shortcomings: the overall structure of the device is small, the opening is small when it is opened, the operation is more troublesome when loading the medicine, and the medicine is prone to spillage when the device is tilted. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a skin medication application device.
[0006] The technical solution of this utility model is as follows: a skin application device, including a storage tube, a cylindrical cavity is provided inside the storage tube, and an air inlet and a discharge outlet are respectively provided at both ends of the cylindrical cavity on the storage tube, and the air inlet is connected to a one-way air inlet pipe.
[0007] The piston is set inside the cylindrical cavity and slidably connected to its inner wall. A one-way feed hole is provided on the piston.
[0008] The drive assembly is connected to the storage tube and drives the piston to slide radially along the cylindrical cavity.
[0009] The control component is connected to the storage pipe and electrically connected to the drive component.
[0010] The adapter assembly connects the storage pipe and the guide cover. The guide cover is provided with a guide pipe that connects its interior and the discharge hole. At the end of the guide cover away from the storage pipe, there are several limiting pipes that communicate with its interior. The limiting pipes are equipped with rolling balls that are in clearance with their inner cavities, and the limiting pipes are equipped with spring rods that push the balls outward.
[0011] Preferably, an anti-slip pad is provided on the storage pipe, heat dissipation holes are provided on the storage pipe, a dustproof screen is provided at the air inlet end of the heat dissipation holes, and a radiator is provided at the air outlet end of the heat dissipation holes.
[0012] Preferably, the drive assembly includes a lead screw and a motor. The lead screw is disposed within a cylindrical cavity and rotatably connected to a storage tube, with its lower end inserted into a heat dissipation hole. The motor is disposed within the heat dissipation hole, with its output end coaxially connected to the end of the lead screw. A limiting rod is disposed within the cylindrical cavity, parallel to the radial direction of the lead screw, and passes through and slidably connects to the piston.
[0013] Preferably, the control component includes a switch, which is a pressure-sensitive switch and is electrically connected to the motor.
[0014] Preferably, a filter ball head is provided at the input end of the one-way air inlet pipe, and the conduction direction of the one-way air inlet pipe is the same as the conduction direction of the one-way feed hole.
[0015] Preferably, a cylindrical groove is provided inside the guide cover, and a disc that is spirally connected to the guide cover is provided inside the cylindrical groove. A feeding channel is provided between the disc and the upper wall of the cylindrical groove, and a limiting tube is provided on the disc and communicates with the inside of the feeding channel.
[0016] Preferably, the adapter assembly includes a support base and an ear plate. The support base is connected to the storage pipe, and two hollow shafts are symmetrically arranged on the support base. The hollow shafts are connected to the discharge hole, and the guide pipe is coaxially connected to the hollow shafts and internally connected.
[0017] Preferably, a suction cup is provided at the end of the storage tube away from the guide cover.
[0018] Compared with the prior art, the present invention has the following beneficial technical effects:
[0019] By setting a one-way air inlet pipe and a one-way feed hole on the piston, with the one-way air inlet pipe and the one-way feed hole having the same direction of conduction, the loading and extrusion of the medicine are achieved by the sliding of the piston. This structure does not require opening the device to add material, making it simple and convenient to operate. Moreover, only cleaning agent and water need to be sucked in during cleaning. At the same time, this utility model is also equipped with a rotatable and adjustable feed guide cover, which further facilitates patients to apply medicine to different parts of the body.

[0024] Example 1
[0025] like Figure 1-Figure 3As shown, this utility model proposes a skin application device, including a storage tube 1, a piston 6, a drive assembly, a control assembly, and a transfer assembly. The storage tube 1 has a cylindrical cavity 101. An air inlet 103 and a discharge port 104, communicating with each other, are respectively provided at both ends of the cylindrical cavity 101. The air inlet 103 is connected to a one-way air inlet pipe 9, and a one-way valve B is installed inside the one-way air inlet pipe 9. An anti-slip pad 3 and a heat dissipation hole 102 are provided on the storage tube 1. A dustproof screen is provided at the air inlet end of the heat dissipation hole 102, and a radiator is provided at the air outlet end. The piston 6 is slidably connected to the inner wall of the cylindrical cavity 101. A one-way guide hole 61 is provided on the piston 6, and a one-way valve A is installed inside the one-way guide hole 61. A filter ball head 10 is provided at the input end of the one-way air inlet pipe 9, and the conduction direction of the one-way air inlet pipe 9 is the same as the conduction direction of the one-way guide hole 61. The drive assembly includes a lead screw 7 and a motor 8. The lead screw 7 is disposed within a cylindrical cavity 101 and rotatably connected to the storage tube 1, with its lower end inserted into a heat dissipation hole 102. The motor 8 is disposed within the heat dissipation hole 102, with its output end coaxially connected to the end of the lead screw 7. A limiting rod 5 is disposed within the cylindrical cavity 101, parallel to the radial direction of the lead screw 7, and passes through and slidably connects to a piston 6. The drive assembly drives the piston 6 to slide radially along the cylindrical cavity 101. The control assembly includes a switch 2, which is connected to the storage tube 1. The switch 2 is a pressure-sensitive switch and is electrically connected to the motor 8. A transfer assembly connects the storage tube 1 and the guide cover 13, and includes a support base 11 and an ear plate 12. The support base 11 is connected to the storage pipe 1, and two hollow shafts 111 are symmetrically arranged on the support base 11. The hollow shafts 111 are connected to the discharge hole 104. The guide pipe 14 is coaxially connected to the hollow shafts 111 and internally connected. A cylindrical groove is provided inside the guide cover 13. A disc 15 is spirally connected to the guide cover 13 inside the cylindrical groove. A feeding channel is provided between the disc 15 and the upper wall of the cylindrical groove. A limiting tube 16 is provided on the disc 15 and is internally connected to the feeding channel. A ball bearing 17 with clearance fitting to its inner cavity is rolled inside the limiting tube 16. A spring rod 18 is provided inside the limiting tube 16 to push the ball bearing 17 outward.
[0026] In this embodiment, the medication is first added to the cylindrical cavity. During medication addition, the filter ball head 10 is inserted into the medication container. Then, the motor 8 is started by pressing the switch 2. The motor 8 drives the lead screw 7 to rotate, which in turn drives the piston 6 to slide towards the discharge port 104. The one-way valve A in the one-way feed port 61 is closed. At this time, the medication enters the cylindrical cavity 101 along the one-way air inlet pipe 9 under the action of negative pressure. Then, the motor 8 is started to rotate in the opposite direction. The motor 8 drives the lead screw 7 to rotate in reverse, which in turn drives the piston 6 to slide back to its original position. At this time, the one-way valve A is opened and the one-way valve B is closed. The medication rises through the one-way feed port 61 to the space between the piston 6 and the discharge port 104. Continuing to drive the piston 6 to slide will squeeze the medication through the feed tube 14 into the feed cover 13. When the roller ball 17 is squeezed by the skin, the medication seeps out along the gap between the limiting tube 16 and the roller ball 17 and is applied to the patient's skin through the roller ball 17. When dragging and applying the medication to different parts of the body, the feed cover 13 rotates adaptively.

[0029] In this embodiment, when placing the device, the suction cup 4 is placed on the placement table, and the suction cup is pressed to expel the air inside, thereby stably adsorbing the device on the table, improving the stability of the device and preventing the device from being easily knocked over.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
