Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a medicine applicator. Background Technology

[0002] A medication applicator is a medical aid used for the precise application of medications, primarily for applying drugs (such as ointments, gels, lotions, etc.) to specific areas of the body. These tools improve accuracy and reduce direct hand contact with the affected area, lowering the risk of cross-infection. However, most medication applicators currently on the market are push-type brush applicators, which use a long, syringe-like handle to push the medication onto a brush head for application. However, this type of applicator makes it difficult to apply the medication precisely and evenly to the application site using only the brush head. Furthermore, the long handle is inconvenient for pushing medication into hidden joints and folds, resulting in a poor user experience. Utility Model Content

[0020] To better understand the purpose, structure, and function of this utility model, the following detailed description of specific embodiments of the utility model "a medicine applicator" is provided in conjunction with the accompanying drawings.

[0021] See Figure 1In this embodiment, the applicator includes an applicator cylinder 100, a fixed baffle 101 fixedly disposed at the rear end of the applicator cylinder 100, an inflatable air bladder 102 and a sliding piston 103 disposed inside the applicator cylinder 100, and an applicator head 200 detachably fixedly disposed at the front end of the applicator cylinder 100. Preferably, the front end of the applicator cylinder 100 is threadedly connected to the rear end of the applicator head 200. A drug storage area is formed between the sliding piston 103 and the applicator head 200. A ball bearing 201 is disposed at the drug outlet of the applicator head 200. The front end of the inflatable air bladder 102 is fixedly connected to the sliding piston 103. An air inlet 104 is disposed at the rear end of the inflatable air bladder 102. The air inlet 104 is fixedly disposed on the fixed baffle 101. One end of the air inlet 104 passes through the fixed baffle 101 and is connected to the air intake device 300 through an air pipe 301.

[0022] In this embodiment, the application device is used by first removing the application head 200, placing the medication in the storage area, compressing the sliding piston 104 to slide backward, causing the expansion and contraction bladder 102 to contract and fill with medication. Then, the application head 200 is reattached, and air is inflated into the expansion and contraction bladder 102 through the air inlet device 300. The expansion and contraction bladder 102 expands and drives the sliding piston 103 to slide forward within the application cylinder 100, squeezing the ointment onto the application head 200. The user then applies the ointment by rolling the ball 201 at the application site through the outlet of the application head 200. This application device, through the rolling motion of the ball, can evenly apply the ointment to the application site. Furthermore, the flexible air tube 301 connects the air inlet device 300 and the expansion and contraction bladder 102 within the application cylinder 100, allowing the user to flexibly move the application head 200 to all areas requiring application. This application device provides a superior user experience.

[0023] Preferably, in this embodiment, the air intake device 300 includes a balloon 302 connected to an air tube 301, and a one-way air intake valve 303 is provided on the balloon 302. Squeezing the balloon 302 compresses it, allowing air to pass through the air tube 301 into the inflatable airbag 102. Releasing the squeeze causes the balloon 302 to rebound, allowing air to enter from the outside through the one-way air intake valve 303. Repeating this squeezing and releasing process inflates the inflatable airbag 102. Of course, in other embodiments, the air intake device 300 can also be an air pump, which inflates the inflatable airbag 102 to achieve automated air intake.

[0024] Furthermore, in this embodiment, the air intake device 300 also includes an opening and closing valve 304, which is disposed on the air tube 301 or the balloon 302. Before filling the ointment, the opening and closing valve 304 is opened to deflate the inflatable balloon 102 so that the sliding piston 103 can be compressed to slide backward, thereby obtaining a larger drug storage area to hold more medicine. After the ointment is filled, the opening and closing valve 304 is closed, and the inflatable balloon 102 is inflated again through the air intake device 300.

[0025] More specifically, in this embodiment, a slide rail 105 is provided inside the application tube 100, and the sliding piston 103 slides along the slide rail 105 inside the application tube 100 to ensure that the sliding piston 103 slides more smoothly and stably.

[0026] Preferably, in this embodiment, the application head 200 is made of a transparent material, and the application tube 100 includes a shaping section 106 and a transparent section 107. The shaping section 106 is made of a transparent deformable material (such as medical-grade transparent silicone) with an embedded steel wire skeleton 108. The shaping section 106 can be adapted to bend and shape, which is convenient for users to have more flexible medication needs. The transparent section 107 is made of a transparent material and is provided with a reading scale. The transparent section 107 is connected to the application head 200, which is convenient for users to observe the amount of medication used and the amount of medication remaining.

[0027] Furthermore, in other embodiments, the entire application tube 100 is a transparent universal tube, and the application tube 100 is provided with a reading scale. In this way, the application tube 100 can be adapted to bend and shape, which facilitates users to apply medicine more flexibly. The transparent application tube 100 and the application head 200, together with the reading scale, make it convenient for users to observe the amount of medicine used and the amount of medicine remaining.
