Description

Technical Field

[0001] The utility model relates to the technical field of medicine applying devices, in particular to an ointment production test applicator. Background Art

[0002] In the production process of ointments, a key link is to detect the efficacy of the ointments. This detection process is carried out by professional testers who will simulate the actual use by patients. By using a rapid applicator, the ointment is evenly applied. During the application process, the testers will carefully observe the therapeutic effect of the ointment on the simulated condition, including observing the absorption of the ointment, tolerance, and whether it will cause allergic reactions, etc. In addition, they will also evaluate the sensory properties of the ointment, such as texture, color, smell, etc., to ensure that it meets the production standards. During the entire drug property test process, the testers will record in detail the amount of ointment applied, the number of application times, and the therapeutic effect, so as to conduct a quantitative analysis of the efficacy of the ointment. This strict test procedure aims to ensure the safety and effectiveness of the ointment and provide high-quality products for the ultimate users. Such tests can not only ensure that the quality of the ointment meets the standards, but also provide accurate treatment information for doctors and patients to help them make more appropriate choices.

[0003] In the patent "An Ointment Application Device" (publication number CN210734951U, hereinafter referred to as the prior art 1), an application device is disclosed. The ointment application device in the prior art 1 mainly applies a force to the pressing plate to drive the movable rod to move inward, so that the movable plate also moves towards the fixed housing, and then the return spring contracts, so that the extrusion plate can move inward, thereby squeezing the ointment box, so that the ointment can flow out through the medicine outlet tube. Through the rotation of the application ball, the ointment can be evenly applied on the skin surface, so that the skin can better absorb the efficacy of the ointment.

[0004] Although the prior art 1 discloses an applicator that can enable better absorption by patients, the application ball in the prior art 1 is fixedly connected to the overall structure and cannot be replaced. During frequent ointment drug property tests, the applicator will quickly become ineffective, and at this time, only the entire applicator can be replaced, resulting in a relatively high use cost for the applicator. Moreover, the number and shape of the application heads in the prior art 1 are fixed and cannot be adaptively replaced according to different test scenarios, which is not conducive to conducting ointment drug property tests in different ways. Content of the Utility Model

[0033] Embodiment 1

[0034] Please refer to Figure 1, the embodiment of the present utility model provides an ointment production test applicator. In the manufacturing process of ointment drugs, there is a crucial link, which is to detect and evaluate the efficacy of the ointment. In this process, professional testers will use a special applicator to evenly apply the ointment on specific test sites, and then carefully observe and record the effects before and after application. The purpose of doing this is to accurately understand the actual therapeutic effect of the ointment on the human body and ensure its safety and effectiveness. Through these rigorous tests, producers can have a comprehensive understanding of the efficacy of the ointment, and then make necessary adjustments and improvements to ensure that the quality of the final product meets medical standards and the needs of patients.

[0035] Please refer to Figure 1 , an ointment production test applicator includes an extrusion mechanism, a cylinder 100, and an applicator head provided at one end of the cylinder 100. The applicator extrudes the ointment through the extrusion mechanism, accommodates it through the cylinder 100, and contacts the part to be applied through the applicator head.

[0036] The working principle of the applicator is mainly to apply pressure to the ointment through its extrusion mechanism, so as to quickly and effectively extrude it to the experimental site and evenly apply it to the test site, generally for the test of the ointment properties. The extruded ointment is placed in the cylinder 100 and temporarily stored for use. When the user contacts the applicator head with the part to be applied, the ointment can flow out from the applicator head and evenly cover the surface of the applied part. This design makes the ointment applicator very convenient and fast in use. The tester only needs to operate the extrusion mechanism, and the ointment can flow out from the applicator head to achieve rapid application for testing. At the same time, the applicator head can well contact the part to be applied, so that the ointment can be evenly applied on the surface, avoiding the problem of uneven application and ensuring the test effect.

[0037] Please refer to Figure 2 , the inside of the cylinder 100 is hollow and used to store the ointment; one end of the cylinder 100 is provided with an opening 110, and the other end is provided with a discharge port 120; the discharge port 120 is provided with a discharge joint 121. The cylinder 100 is designed with a hollow structure inside, so that it can conveniently store ointment substances. One end of the cylinder 100 is designed to be open for easy loading of the ointment, while the other end is provided with a discharge port 120 for easy discharge of the ointment during use. At the part of the discharge port 120, a discharge joint 121 is also equipped. This joint plays a bridging role. The discharge joint 121 is used to engage with the applicator head, so that the ointment in the cylinder 100 can be communicated with the applicator head, so that the ointment can be smoothly taken out from the cylinder 100 and applied to the predetermined test site.

[0038] Please refer toFigure 1 , a thread is provided on the body of the discharge joint 121; the applicator head is detachably connected to the discharge joint 121 through the thread. A thread structure is provided on the discharge joint 121, which enables the discharge joint 121 to be flexibly detached and connected to the applicator head. Specifically, the applicator head is screwed into or rotated into the thread on the discharge joint 121, and with the fastening effect of the thread, the applicator head can be firmly connected to the discharge joint 121. When disassembly is required, simply gently rotate the applicator head to disengage it from the thread of the discharge joint 121, and the separation of the two can be achieved. This detachable connection method not only simplifies the maintenance and cleaning process of the equipment but also improves the replacement efficiency of the applicator head. Moreover, it provides the same quality of ointment for different test sites, and at the same time, various different applicator heads can be used, which ensures the consistency and reliability of the ointment test. The advantage of this is that regardless of the specific situation of the test site, the curative effect during the ointment test is the same. Because the diversity of the applicator head can be selected according to the skin type of the test site, the size and shape of the lesion, and the treatment needs to achieve a reliable test effect.

[0039] Please refer to Figure 2 , the extrusion mechanism includes an extrusion rod 210 and a pressing block 220; the pressing block 220 is provided at one end of the extrusion rod 210 and is disposed inside the cylinder 100 through the opening 110. The extrusion mechanism is mainly composed of two parts, namely the extrusion rod 210 and the pressing block 220; among them, the pressing block 220 is arranged at one end of the extrusion rod 210 and is located inside the cylinder 100 through the opening 110 device. The design of this structure enables the pressing block 220 to effectively compress the ointment in the cylinder 100 under the action of the extrusion rod 210, so as to achieve the expected extrusion effect. The pressing block 220 is fixedly connected to the extrusion rod 210. By driving the extrusion rod 210, the pressing block 220 is driven to apply pressure to the ointment inside the cylinder 100, so that it is discharged from the discharge port 120.

[0040] Please refer to Figure 2, the cross-sectional shape of the pressing block 220 is adapted to the inner cross-sectional shape of the cylinder 100; by applying a force to the extrusion rod 210, the pressing block 220 discharges the ointment from the discharge port 120. The cross-sectional shape of the pressing block 220 and the corresponding inner cross-sectional shape of the cylinder 100 are in exact conformity with each other. This precise matching ensures that the extrusion of the ointment can be carried out efficiently during operation. When an external force acts on the extrusion rod 210, this pressing block 220 can perform its function and smoothly discharge the viscous substance of the ointment through the discharge port 120. Due to the extremely high adaptability between the pressing block 220 and the cylinder 100, their connection part is very tight, which ensures an important result: the ointment can be completely discharged during extrusion without any residue. In practical applications, this characteristic of tight connection is particularly important because it reduces the waste of the ointment and ensures that the amount extruded each time is uniform and accurate. The discharge port 120 is communicatively connected to the applicator head.

[0041] Please refer to Figure 1 and Figure 2 , the extrusion mechanism further includes an inner cylinder 230 and an outer cylinder 240, and the inner cylinder 230 and the outer cylinder 240 are connected by threads. This enables the outer cylinder 240 to rotate based on the inner cylinder 230. The inner cylinder 230 is sleeved on the outer surface of the cylinder 100; the outer cylinder 240 is sleeved on the outer surface of the inner cylinder 230 and moves up and down based on the inner cylinder 230. During use, generally an external force is applied to the extrusion rod 210, but the extrusion rod 210 is rod-shaped and the force is not evenly distributed. Therefore, a screw extrusion mechanism is provided. There is no need to apply an external force for pressurization. Only by rotating the outer cylinder 240, through the threaded connection between the outer cylinder 240 and the inner cylinder 230, the outer cylinder 240 can be raised or lowered; the inner cylinder 230 is fixedly connected to the cylinder 100.

[0042] The described extrusion mechanism not only includes the main extrusion components but also the inner cylinder 230 and the outer cylinder 240, which are connected by threads to achieve rotation and movement relative to each other. This design enables the outer cylinder 240 to rotate around the inner cylinder 230, while the inner cylinder 230 is tightly sleeved on the outer surface of the cylinder 100. At the same time, the outer cylinder 240 is sleeved on the outer surface of the inner cylinder 230 and can move up and down based on the inner cylinder 230. Such a structural design enables the inner cylinder 230 to be raised or lowered by rotating the outer cylinder 240 during use, thereby achieving the purpose of extrusion.

[0043] The usage method of this extrusion mechanism is very simple. Usually, we only need to apply an external force to the extrusion rod 210. However, since the extrusion rod 210 is rod-shaped, the force is not uniform during the force application process. To solve this problem, a screw extrusion mechanism is set up, so that there is no need to apply an external force for pressurization. Only by rotating the outer cylinder 240, the rise or fall of the outer cylinder 240 can be realized through the threaded connection between the outer cylinder 240 and the inner cylinder 230. A rectangular card slot 241 is provided at the top of the outer cylinder 240; a card block 211 adapted to the rectangular card slot 241 is provided on the extrusion rod 210; the extrusion rod 210 is clamped with the rectangular card slot 241 through the card block 211. Since the extrusion rod 210 and the outer cylinder 240 are clamped, when the outer cylinder 240 rises or falls, the rising extrusion rod 210 also rises or falls with the outer cylinder 240, and the pressing block 220 will extrude or release the ointment to complete the extrusion work.

[0044] In addition, it is worth noting that the inner cylinder 230 is fixedly connected to the cylinder body 100, which can ensure the stability of the inner cylinder 230 during the extrusion process, thereby improving the extrusion efficiency and quality.

[0045] Please refer to Figure 1 , preferably, a rotating handle 212 is provided at the top end of the extrusion rod 210. Driving the rotating handle 212 causes the outer cylinder 240 to rise and fall based on the inner cylinder 230, driving the pressing block 220 to rise and fall. A rotating handle 212 convenient for operation is designed at the top end of the extrusion rod 210. Through this rotating handle 212, the operator can easily drive the outer cylinder 240 to move up and down according to the position of the inner cylinder 230, thereby realizing the up and down movement control of the pressing block 220. This not only improves the operation convenience but also makes the entire mechanism more flexible and efficient.

[0046] Embodiment 2

[0047] Please refer to Figure 1 and Figure 4 , the embodiment of the present invention provides an ointment rapid applicator. The applicator head is a single ball applicator head 310. The single ball applicator head 310 includes a connection block 311, a roller 312 and a ball 313. The ball 313 rotates based on the roller 312; the discharge port 120 is communicated with the roller 312. The special ball 313 ointment applicator head of the ball 313 type can ensure that the ointment is evenly applied and can perform a large rotational pressing on the test site, so that the test site can penetrate and absorb the ointment.

[0048] Furthermore, please refer to Figure 3, the applicator head adopts a unique single ball 313 design. The single ball applicator head 310 consists of a connecting block 311, a roller 312, and a ball 313. The ball 313 works by rotating around the roller 312. In addition, a communication channel is provided between the discharge port 120 and the roller 312 to ensure the smooth flow of the ointment. The ointment is continuously extruded and flows onto the ball 313. Through the roller 312 of the ball 313, it continuously contacts the test site and applies the ointment to the test site. The ball 313 type ointment applicator head aims to ensure that the ointment can be evenly applied to the test site, and through the pressing action generated by the rolling of the ball 313, it helps the test site better absorb the ointment components, which can not only improve the use effect of the ointment but also ensure the accurate determination of the medicinal properties of the ointment.

[0049] Example 3

[0050] Please refer to Figure 1 and Figure 5 , an embodiment of the present invention provides an ointment rapid applicator. The applicator head is a multi-ball applicator head 320, and the multi-ball applicator head 320 includes a connecting block 311 and multiple pairs of rollers 312 and balls 313; the balls 313 rotate based on the rollers 312; the discharge port 120 communicates with the multiple rollers 312. The specially designed ball 313 ointment applicator head of the multi-ball 313 type can ensure even application of the ointment and perform relatively intensive pressing on the test site, thereby enabling the test site to penetrate and absorb the ointment.

[0051] Please refer to Figure 3 , the multi-ball applicator head 320 is an ointment applicator composed of a connecting block 311, multiple rollers 312, and balls 313. In this structure, the balls 313 are installed on the rollers 312 and can rotate around the rollers 312. This design enables the balls 313 to better contact the rollers 312, so that the ointment can be more evenly applied to the test site. In addition, the discharge port 120 is connected to the multiple rollers 312, ensuring that the ointment can smoothly flow out of the rollers 312 and be applied to the test site.

[0052] This multi-ball 313 type ointment applicator can ensure even application of the ointment and can also perform intensive pressing on the test site. The multi-ball 313 type applicator head can be provided with multiple balls 313 such as three, four, five, etc. to cover a larger and denser application area. This multi-ball 313 type ointment applicator can promote the penetration and absorption of the ointment by the test site, thereby improving the test effect of the medicinal properties of the ointment.

[0053] Example 4

[0054] Please refer to Figure 1and Figure 6 In an embodiment of the present utility model, a quick ointment applicator is provided. The applicator head is a cotton ball applicator head 330, and the cotton ball applicator head 330 includes a connecting block 311 and a pipe 331; the pipe 331 is connected to the discharge joint 121; the end of the cotton ball applicator head 330 is provided with a medical sponge ball 322.

[0055] Furthermore, please refer to Figure 7 , the applicator head used is the cotton ball applicator head 330, which is composed of a connecting block 311 and a pipe 331; one end of the pipe 331 is connected to the discharge joint 121 to facilitate the smooth delivery of the ointment; the other end of the cotton ball applicator head 330 is designed as a medical sponge ball 322. By squeezing the ointment onto the sponge ball, it can be in close contact with the test site, realizing the application operation, making the application process more gentle and comfortable when contacting the test site. In this way, not only can the ointment be evenly applied, but also the irritation to the test site can be effectively reduced, obtaining different test effects, and further ensuring the accuracy of the ointment drug property test.

[0056] An extrusion member 333 is provided inside the connecting block 311; the extrusion member 333 is connected to a rotating handle 334, and the rotating handle 334 drives the extrusion member 333 to contact or move away from the pipe 331. The cotton ball applicator head 330 uses the pipe 331 to transport the ointment, and the ointment may remain in the pipe 331 and cannot be output. Therefore, the extrusion member 333 is provided. By rotating the rotating handle 334, the extrusion member 333 is in contact with the pipe 331 for extrusion, so that the ointment inside the pipe 331 is extruded. After the extrusion is completed, the extrusion member 333 is rotated to a position where it does not contact the pipe 331 to avoid blocking the pipe 331.

[0057] Furthermore, the present utility model uses multiple applicator heads to apply the ointment to the test site multiple times, tests the drug properties of each ointment application respectively, and comprehensively analyzes all the results to judge the safety and effectiveness of the ointment drug properties. Through the comprehensive analysis of multiple tests, it is made more accurate.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
