Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically a retractable medicine applicator. Background Technology

[0002] The medication applicator is a very practical medical device with advantages such as precise application of medication to the affected area, ease of operation, safety and reliability, and large disinfection area. This device is widely used in preoperative skin disinfection, especially in Europe and America, where the use of medication applicators has replaced traditional disinfection swabs. With the development and progress of medical technology, medication applicators will play an even more important role in medical practice.

[0003] The existing technology has the following shortcomings: Application number 202321622566.9 proposes a retractable medication applicator, including a first fixed rod and a pressing plate. The top of the first fixed rod is fitted with a second fixed rod, and the bottom of the second fixed rod has a cavity containing a retractable locking device. The top of the second fixed rod has a U-shaped seat, with fixing posts at both ends of one side of the U-shaped seat. A scraper is attached to the end of the U-shaped seat near the threaded hole, and fixing devices are located at the bottom of the two fixing posts. A medication-storing airbag is located inside the U-shaped seat. One end of the pressing plate abuts against the bottom outer wall of the medication-storing airbag, and the other end has a pressing block. This invention uses the cooperation of the retractable first and second fixed rods and the locking device to fix the length of the device. The patient can extend and retract the device as needed to apply medication themselves. The patient can press the rubber pad with their skin, causing the pressing plate to squeeze the medication-storing airbag, squeezing out an appropriate amount of medication. Simultaneously, the scraper smooths the medication. The operation is simple and convenient.

[0004] The aforementioned equipment uses a squeezing method to press the medicine onto the scraper by squeezing the medicine storage bladder. However, this method cannot control the amount of medicine squeezed out, thus affecting the effectiveness of the application stick when applying the medicine. Furthermore, most existing application sticks are telescopic structures and do not have a limiting structure. When the second fixing rod of the application stick is extended outward, it will cause the second fixing rod to swing. When the second fixing rod swings, it will affect the stability of the application stick and thus affect the application effect. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 In this embodiment: a retractable application stick includes an application stick body 1, a handle 2 at the bottom end of the application stick body 1, an adjustment hole 3 on the front surface of the application stick body 1, a limit bolt 4 inside the adjustment hole 3, an adjustment rod 5 inside the application stick body 1, an application plate 6 at the top end of the adjustment rod 5, a limit block 7 at the bottom end of the adjustment rod 5, a limit hole 8 on the front surface of the limit block 7, a slot 9 at the back end of the limit block 7, and a retaining strip 10 on the inner wall of the application stick body 1.

[0024] Reference Figure 1-3 The number of adjustment holes 3 is several sets, and the adjustment holes 3 are equidistantly embedded on the front surface of the main body 1 of the application stick.

[0025] Specifically: By setting multiple sets of adjustment holes 3, the adjustment rod 5 can be adjusted to different lengths, thereby improving the performance of the main body 1 of the application stick.

[0026] Reference Figure 2 and Figure 4 The outer diameter of the adjusting rod 5 matches the inner diameter of the main body 1 of the application stick. The adjusting rod 5 is sleeved inside the main body 1 of the application stick, and the bottom end of the adjusting rod 5 is fixedly connected to the limiting block 7. The application plate 6 is made of silicone and is fixedly installed on the top of the adjusting rod 5.

[0027] Specifically: by setting the limit block 7, the stability of the adjusting rod 5 can be improved, and the adjusting rod 5 can be prevented from falling off during use; and by making the medicine application plate 6 with silicone, the comfort of using the medicine application plate 6 can be improved.

[0028] Reference Figure 4-5 The limiting hole 8 is fixedly installed on the front surface of the limiting block 7, and the limiting hole 8 is threadedly connected to the limiting bolt 4; there are two sets of slots 9, which are symmetrically embedded on the back end of the limiting block 7, and the slots 9 are engaged with the locking strips 10; there are two sets of locking strips 10, which are symmetrically installed in the inner wall of the main body 1 of the application stick.

[0029] Specifically: By threading the limiting hole 8 and the limiting bolt 4, the fixing effect of the adjusting rod 5 can be improved, and the sliding of the adjusting rod 5 during use can be prevented; by setting two sets of slots 9 and two sets of clips 10, the limiting effect of the limiting block 7 can be improved, thereby improving the stability of the limiting block 7 in use.

[0030] The working principle and usage process of this utility model are as follows: When using the main body 1 of the application stick, the operator pulls the adjusting rod 5 outward according to the required length. After pulling the adjusting rod 5 to the appropriate position, the operator checks the position of the limiting hole 8 through the adjusting hole 3, and then makes a fine adjustment to align the adjusting hole 3 with the limiting hole 8. Once the adjusting hole 3 and the limiting hole 8 are aligned, one end of the limiting bolt 4 is threaded through the inner wall of the adjusting hole 3 and connected to the limiting hole 8. In this way, the adjusting rod 5 is limited by the cooperation of the adjusting hole 3, the limiting bolt 4, and the limiting hole 8, preventing the adjusting rod 5 from moving during use and thus affecting the application of the medicine. The use of the main body 1 improves the ease of use. After fixing the adjusting rod 5, the medicine is evenly applied to the surface of the application plate 6. Then, by holding the handle 2 and using the reflection of the mirror, the application plate 6 installed on the main body 1 is moved to the wound. The medicine on the application plate 6 is then evenly applied to the wound. During the use of the main body 1, the cooperation between the slot 9 and the locking strip 10 on one side of the limiting block 7 can limit the movement of the limiting block 7, preventing it from swinging during movement. This improves the stability of the main body 1.
