Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an ultrasound anti-infection coating device. Background Technology
[0002] Ultrasound is a specialized department in medicine that primarily uses ultrasound technology for diagnosis and treatment. Ultrasound waves are sound waves with frequencies higher than the range of human hearing and are commonly used in medical imaging examinations. Ultrasound uses high-frequency sound waves to image the internal structure of the human body, helping doctors understand the morphology, structure, and function of organs and tissues. It is widely used in disease screening, diagnosis, and monitoring. Anti-infection coating devices typically refer to equipment used in industries such as medical care, laboratories, food processing, and pharmaceuticals for applying and treating disinfectants, antibacterial agents, and anti-infection agents.
[0003] Ultrasound-guided anti-infection spray devices are typically designed with a fixed spray head. Their structure includes the spray head, disinfectant storage container, dispensing system, and triggering mechanism. The spray head is specially designed to ensure even application of disinfectant upon skin contact.
[0004] In existing technologies, during some ultrasound examinations, doctors and technicians often need to use the same smear head to examine multiple patients, which increases the risk of cross-infection to some extent. Especially in a hospital environment, patients may carry different pathogens. If the same smear head is used without adequate disinfection, it can lead to the spread of pathogens and endanger patients' health. Therefore, an anti-infection smear device for ultrasound departments is proposed to solve the above problems. Utility Model Content
[0005] This invention proposes an ultrasonic anti-infection coating device, which aims to improve the problem that some existing devices cannot avoid cross-infection.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An ultrasound-guided anti-infection coating device includes a cylindrical storage cavity. A circular barrier plate is fixedly connected to the lower end of the cylindrical storage cavity. Multiple cylindrical sliding transfer cavities are slidably connected inside the circular barrier plate. Multiple coating liquid transfer holes are formed on the upper surface of each cylindrical sliding transfer cavity. A limiting anti-slip ring is fixedly connected to the lower outer end of each cylindrical sliding transfer cavity. A replaceable skin-contacting cotton sleeve is slidably connected to the outside of the limiting anti-slip ring.
[0008] As a further description of the above technical solution:
[0009] An absorbent sponge pad is fixedly connected to the top of the circular barrier plate, and multiple limiting spheres are slidably connected inside the circular barrier plate.
[0010] As a further description of the above technical solution:
[0011] The lower outer end of the cylindrical sliding transmission cavity is fixedly connected to a lower limiting ball, and the upper outer end of the cylindrical sliding transmission cavity is fixedly connected to the inside of the upper limiting ball.
[0012] As a further description of the above technical solution:
[0013] The bottom of the cylindrical storage cavity is fixedly connected to multiple leak-proof rubber rings, and the inside of the leak-proof rubber rings is slidably connected to the outside of the limiting sphere.
[0014] As a further description of the above technical solution:
[0015] An anti-slip touch pad is fixedly connected to the upper outer part of the cylindrical storage cavity, and an inlet is fixedly connected to the top of the cylindrical storage cavity.
[0016] As a further description of the above technical solution:
[0017] The lower outer end of the cylindrical storage cavity is threaded with a protective support cover.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, by holding the anti-slip touch pad, the cylindrical storage cavity is pressed downward on the patient's skin, so that the liquid inside the cylindrical storage cavity is transferred from the cylindrical sliding transfer cavity to the replaceable skin-contact cotton sleeve, thereby evenly applying the medicine to the patient's skin. The replaceable skin-contact cotton sleeve can be replaced by the limiting anti-slip ring, thereby avoiding multiple people using one replaceable skin-contact cotton sleeve and avoiding the risk of cross-infection caused by multiple people sharing it.
[0020] 2. In this utility model, by holding the anti-slip touch pad, the cylindrical storage cavity is pressed downward on the patient's skin, causing the cylindrical sliding transfer cavity to move into the cylindrical storage cavity. Thus, the liquid inside the cylindrical storage cavity is transferred into the cylindrical sliding transfer cavity through the coating liquid transfer hole. Furthermore, the vertical movement range of the cylindrical sliding transfer cavity is limited by the upper and lower limiting spheres, achieving the effect of convenient application.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0027] Reference Figures 1 to 3 One embodiment of this utility model is an ultrasound anti-infection coating device, which includes a cylindrical storage cavity 1. The cylindrical storage cavity 1 serves as the main structure of the entire anti-infection coating device. It has a standard cylindrical shape, a smooth and uniform outer surface, and good chemical stability. It can stably store various coating solutions for a long time without reacting chemically with the coating solutions and affecting their properties. Furthermore, its transparent nature allows medical staff to easily observe the remaining amount of coating solution inside and replenish it in a timely manner.
[0028] A circular baffle plate 2 is fixedly connected to the lower end of the cylindrical storage cavity 1. The circular baffle plate 2 has a circular plate-like structure, resembling a flat "disc". It can withstand a certain pressure from the coating liquid above without being too heavy, and it has good chemical stability, preventing interaction with the coating liquid. This ensures the integrity of its structure and the isolation effect on the coating liquid during long-term use. Multiple cylindrical sliding transfer cavities 4 are slidably connected inside the circular baffle plate 2. The cylindrical sliding transfer cavities 4 have a slender cylindrical shape, resembling small "cylinders". They are made of medical-grade plastic, which has good chemical stability, a certain degree of flexibility, and smooth inner and outer surfaces. This ensures that the coating liquid flows smoothly inside without chemically reacting with it.
[0029] Multiple dyeing liquid transmission holes 5 are provided on the upper surface of the cylindrical sliding transfer cavity 4. The dyeing liquid transmission holes 5 are usually circular in shape, so that the dyeing liquid adsorbed in the absorbent sponge pad 3 can be transported to the outside through these holes at a certain flow rate and uniformity, thereby achieving the purpose of uniform coating. A limiting anti-slip ring 9 is fixedly connected to the lower outer end of the cylindrical sliding transfer cavity 4. The limiting anti-slip ring 9 has an overall ring structure, and its shape is a "ring". It is made of rubber material with good elasticity and friction. When the cylindrical sliding transfer cavity 4 is connected and cooperated with the replaceable skin-adhesive cotton sleeve 10, it increases the friction between the two and prevents loosening or displacement during use, ensuring the stability of the connection.
[0030] The external sliding connection of the limiting anti-slip ring 9 is a replaceable skin-contact cotton sleeve 10, which is made of soft and highly absorbent medical degreased cotton. It can quickly and evenly apply the dye solution to the skin. Because it is replaceable, it is convenient for medical staff to replace it after one use, avoiding the risk of cross-infection and ensuring hygiene and safety during the ultrasound examination. The lower external end of the cylindrical storage cavity 1 is threaded with a protective support cover 13. The protective support cover 13 is made of medical-grade plastic, which has good strength and toughness. It can firmly cover the lower end of the cylindrical storage cavity 1, playing a dual role of protecting the internal cylindrical sliding transmission cavity 4 and providing support.
[0031] Reference Figures 1 to 3 An absorbent sponge pad 3 is fixedly connected to the top of the circular barrier plate 2. The absorbent sponge pad 3 is a circular sheet structure similar in shape to the circular barrier plate 2. It is made of medical sponge material with good water absorption and softness, which can absorb a large amount of coating liquid. When the cylindrical sliding transfer cavity 4 is squeezed, it can evenly send the coating liquid from the coating liquid transfer hole 5 into the cylindrical sliding transfer cavity 4, playing an important role in buffering and evenly distributing the coating liquid.
[0032] Multiple upper limiting spheres 6 are slidably connected inside the circular barrier plate 2. Their material and function are the same as those of the lower limiting spheres 7. The lower outer end of the cylindrical sliding transmission cavity 4 is fixedly connected to the lower limiting spheres 7. The lower limiting spheres 7 are spherical in shape and are made of medical-grade plastic with a certain degree of hardness and a smooth surface. They work in conjunction with the upper limiting spheres 6 to limit the sliding range of the cylindrical sliding transmission cavity 4, ensuring that it slides within a reasonable range and guaranteeing the normal operation of the device. The upper outer end of the cylindrical sliding transmission cavity 4 is fixedly connected to the inside of the upper limiting spheres 6.
[0033] Multiple leak-proof rubber rings 8 are fixedly connected to the bottom of the cylindrical storage cavity 1. The leak-proof rubber rings 8 are in the form of a ring and are tightly fitted to the bottom edge of the cylindrical storage cavity 1. They are made of rubber with good elasticity and sealing properties, such as medical silicone. They can fit tightly to the surface of the contact limiting ball 7 and effectively prevent the coating liquid from leaking out from the connection between the bottom of the cylindrical storage cavity 1 and other components, thus ensuring the sealing and safety of the entire device during use.
[0034] The leak-proof rubber ring 8 is internally slidably connected to the outside of the limiting ball 7. The upper part of the cylindrical storage cavity 1 is fixedly connected to an anti-slip touch pad 11, which is made of soft silicone material with good friction. This makes the touch pad comfortable to hold. When medical staff operate the device, they can hold the cylindrical storage cavity 1 more firmly through the friction between the touch pad and their hand, avoiding accidents such as the device falling due to slipping. This also increases the convenience and comfort of operation. The top of the cylindrical storage cavity 1 is fixedly connected to an inlet 12, which is tubular in shape. The opening of the tube is polished smooth to facilitate the accurate and smooth injection of the dyeing solution into the cylindrical storage cavity 1 by medical staff.
[0035] Working Principle: First, medical staff inject the dyeing solution into the cylindrical storage chamber 1 through the inlet 12. Due to the transparency of the cylindrical storage chamber 1, medical staff can observe the remaining amount of dyeing solution at any time for timely replenishment. After entering the cylindrical storage chamber 1, the dyeing solution is largely absorbed by the absorbent sponge pad 3. When application is required, by holding the non-slip touch pad, the cylindrical storage chamber 1 is pressed downwards against the patient's skin. The sliding of the cylindrical sliding transfer chamber 4 allows the dyeing solution to be delivered to the outside through the dyeing solution delivery hole 5 at a certain flow rate and uniformity, thus achieving the purpose of uniform application. During this process, the upper limiting ball 6 and the lower limiting ball 7 work together to limit the sliding range of the cylindrical sliding transfer chamber 4, ensuring that it slides within a reasonable range and guaranteeing the normal operation of the device. The dyeing solution is delivered through the cylindrical sliding transfer chamber 4 to the replaceable skin-contact cotton sleeve 10, and then evenly applied to the skin. After each use, it is convenient for medical staff to replace, avoiding the risk of cross-infection.
[0036] Throughout the operation, the anti-slip touch pad 11 provides a comfortable grip, allowing medical staff to hold the cylindrical storage cavity 1 more firmly. Simultaneously, the leak-proof rubber ring 8 fits tightly against the bottom edge of the cylindrical storage cavity 1, effectively preventing the coating solution from leaking out from the connection points between the bottom of the cylindrical storage cavity 1 and other components. Through this design, the ultrasound anti-infection coating device of this invention achieves uniform application of the coating solution, avoiding the risk of cross-infection and improving the safety and efficiency of ultrasound examinations.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
