Description

Technical Field

[0001] This invention relates to the field of drug spraying device technology, specifically a device for precise spraying of medication for perianal pruritus. Background Technology

[0002] A pesticide spraying device is a mechanical system specifically designed to spray, atomize, and coat various pesticides onto target surfaces in a precise, uniform, and controllable manner. Its working principle is based on fluid mechanics, atomization theory, and precision control technology. By optimizing the interaction mechanism between the pesticide and the target surface, it achieves a spraying effect with uniform coating thickness, comprehensive coverage, and high pesticide utilization. It is widely used in various fields such as agricultural plant protection, medical and health care, food processing, electronics manufacturing, and industrial corrosion prevention. It is a key piece of equipment for ensuring the effective application of pesticides and improving operational efficiency and quality.

[0003] Existing medication spray devices for perianal pruritus present challenges during treatment due to the complex conditions in the perianal area. Excessive skin folding caused by natural skin folds, deep fat accumulation due to obesity, and physiological structures such as anal hair create multiple physical barriers. This prevents the medication from penetrating deep folds and areas obscured by anal hair, resulting in insufficient actual coverage. Furthermore, manual assistance is required to stretch the skin and part the anal hairs, increasing the risk of cross-infection. The difference in skin elasticity in obese patients also leads to poor stability during manual operation, causing excessive deviation in the medication spray position and severely impacting treatment effectiveness.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] REFERENCE Figures 1-8 ​As shown, the present application provides a perianal pruritus liquid medicine precision spraying device, which comprises: a detection mechanism 1, four sliding mechanisms 2 and four opening mechanisms 3.

[0022] When using the device to spray liquid medicine on the perianal pruritus site, first, people need to carefully approach the perianal affected area with the whole device, and in this process, the camera 107 installed on the detection mechanism 1 can capture the picture information of the affected area and the surrounding area in real time. These pictures will be clearly displayed on the receiving end such as mobile phone through wireless transmission. People can accurately adjust the position and angle of the device by observing the pictures on the mobile phone screen, ensuring that the medicine spraying head 105 on the detection mechanism 1 can accurately aim at the affected area, and fully prepare for the subsequent precise medicine spraying. When confirming that the medicine spraying head 105 is aimed at the affected area, the external liquid medicine can smoothly pass through the medicine spraying head 105 through the pipeline connected thereto and be uniformly sprayed to the affected area, realizing the preliminary liquid medicine spraying operation. Then, considering that the perianal skin is special, the skin around the affected area often has folds or wrinkles, etc. These wrinkles will affect the overall spraying of the liquid medicine, causing part of the affected skin to not fully contact the liquid medicine, thereby affecting the treatment effect. At this time, people need to fix the four opening mechanisms 3 to the skin around the affected area respectively. After fixing the opening mechanisms 3, start the detection mechanism 1. The detection mechanism 1 will transmit power accurately to the four opening mechanisms 3 through the transmission action of the sliding mechanism 2, and drive the four opening mechanisms 3 to move in different directions, so that the skin around the affected area can be uniformly and effectively tightened, avoiding the problem of liquid medicine accumulation or omission caused by skin wrinkles. In actual use, there may be no need to stretch the skin in four directions at the same time. People start the internal structure of the sliding mechanism 2, which can drive the four opening mechanisms 3 to move as a whole, so that they form two groups. These two groups of opening mechanisms 3 apply stretching force to the skin from two opposite directions, which effectively opens the skin and provides good conditions for liquid medicine spraying. This flexible opening method makes the device adapt to the skin condition and actual needs of different patients, improving the universality and practicality of the device. There are usually anal hairs around the perianal area, which may hinder the spraying of liquid medicine. When encountering the situation that there are anal hairs around the affected area, one group of opening mechanisms 3 will first fix the skin, and then the other group of opening mechanisms 3 will be inserted into the anal hair. The two groups of mechanisms will move outward under the drive of the sliding mechanism 2. In the moving process, this group of opening mechanisms 3 gradually pushes the anal hair to both sides, forming a relatively open space, so that the liquid medicine sprayed by the medicine spraying head 105 can smoothly reach the affected area without being disturbed by the anal hair.

At this time, the gear two 204 rotates again, which drives the two vacuum suction cups 307 on both sides to move outward, thereby tightening and stretching the skin again. The design of the flexible adjustment of the position of the stretching mechanism 3 enables the device to adapt to different shapes and sizes of the affected area, thereby improving the versatility and practicality of the device. When the surrounding hair blocks the spraying of the liquid medicine, the device will start the special hair pushing function. At this time, only two air cylinders one 305 are started to drive the corresponding vacuum suction cups 307 to move and adsorb the skin. The adsorption positions of the two vacuum suction cups 307 are selected at appropriate positions near the hair to ensure that the skin can be effectively fixed and used as a support point for pushing the hair. Subsequently, two air cylinders two 308 are started, and the piston rod two 309 inside the air cylinder two 308 pushes the piston rod two 309 to move downward, and the piston rod two 309 drives the two flexible pushing sheets 310 to stably descend until the flexible pushing sheets 310 are inserted into the hair. The flexible pushing sheets 310 are made of soft and elastic materials and will not cause damage to the skin and hair during insertion. As the gear two 204 rotates, the two vacuum suction cups 307 move outward to tighten the skin, and the two flexible pushing sheets 310 also start to move outward. During movement, the flexible pushing sheets 310 gently push the hair to the two sides to open a smooth channel for the liquid medicine, which facilitates the spraying of the liquid medicine on the affected skin and avoids the blockage and adsorption of the hair, thereby improving the utilization rate of the liquid medicine and the treatment effect.
