Abstract
Description
Technical Field
[0001] This invention relates to the field of skin testing technology, specifically a pressure atomization device for delivering allergens into the skin. Background Technology
[0002] Intradermal allergen delivery refers to a technique that uses pressure to atomize allergen test reagents into tiny droplets, allowing them to quickly and evenly penetrate the skin's surface and superficial dermis to complete an allergen skin test. Its core principle is to break through the barrier of the skin's stratum corneum through atomization, allowing the allergen reagent to come into efficient contact with sensitized cells in the skin, thereby rapidly inducing a specific immune response to identify the type of allergen.
[0003] Most existing delivery devices use manual pressing or gravity dripping to deliver reagents, which cannot achieve atomized delivery of reagents. This results in slow reagent penetration, significantly prolonging the skin test time and delaying subsequent medical treatment. Moreover, manual operation makes it difficult to accurately control the pressure and dosage of reagent delivery, which can easily lead to reagent waste and inaccurate test results. Summary of the Invention
[0004] The purpose of this invention is to provide a pressure atomization device for delivering allergens into the skin, thereby solving the problem of inconvenience in using existing allergen delivery devices.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A pressure atomization intradermal allergen delivery device includes a base, an electrical control box and a guide rail on the base, an air compressor on the electrical control box, an air inlet pipe on the air compressor's air inlet and an air outlet pipe on the air compressor's air outlet, a support block on the guide rail, and a fixing cylinder on the support block. A liquid storage tank and an atomizing tank are respectively housed inside the two fixing cylinders. The air outlet pipe is connected to the inside of the liquid storage tank. A connecting plate is provided on the side of the liquid storage tank and the atomizing tank that is close to each other. A connecting rod and a fixing groove are respectively provided on the two connecting plates. The connecting rod passes through the fixing groove and is fitted with a locking nut for connecting and fixing the liquid storage tank and the atomizing tank.
[0007] The electrical control box is equipped with an adjustment knob and a control switch on its exterior. The outer wall of the atomizing can is equipped with an output pipe. The air compressor uses compressed gas pressure as power to deliver high-pressure gas to the connection between the liquid storage tank and the atomizing can, causing the liquid reagent in the liquid storage tank to be sprayed out and atomized. The atomized reagent is then regulated by the pressure of the atomizing can and output from the output pipe to the test sealed chamber connected to the skin test site, thus outputting test reagent to the skin test site.
[0008] Based on the above technical solutions, the present invention also provides the following optional technical solutions:
[0009] In one alternative: the side wall of the fixed cylinder is provided with a connecting block, and two connecting blocks are respectively provided with a screw and a slot, one end of the screw passes through the slot and is provided with a nut.
[0010] In one alternative: a lead screw is provided inside the guide rail, a fixing nut is provided on the support block, the lead screw passes through the fixing nut and is threadedly engaged with it, and one end of the lead screw extends out of the guide rail and is provided with a handle.
[0011] In one alternative: a control box is provided outside the electrical control box, and an adjustment button is provided inside the control box.
[0012] In one alternative: the air compressor is provided with a filter cartridge, and one end of the air intake pipe extends into the interior of the filter cartridge.
[0013] In one alternative: a flange is provided on the outside of the liquid storage tank, and the vent pipe is connected to the liquid storage tank through the flange.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] The pressure atomization skin allergen delivery device uses compressed gas from an electric air compressor as power. The compressor pressure is controlled by adjusting a knob. High-pressure air is sprayed out as atomized liquid through the connection of the liquid tank, forming atomized pressure. The appropriate test pressure is adjusted inside the tank and output from the outlet. The outlet is connected to a test sealed chamber to deliver test reagents to the skin test site. The device is simple to operate and easy to use. Atomization allows the test reagents to quickly enter the skin, reducing test time and improving medical treatment time. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0023] like Figure 1-4 As shown, an embodiment of the present invention provides a pressure atomization intradermal allergen delivery device, including a base 1. An electrical control box 2 and a guide rail 12 are mounted on the base 1. An air compressor 3 is mounted on the electrical control box 2. The air compressor 3 has an air inlet pipe 8 and an air outlet pipe 13. The electrical control box 2 serves as the electrical control core of the entire device, integrating a control circuit board, a power module, and signal transmission components. It controls the start-up, stop, and operating power of the air compressor 3. The air compressor 3 draws in outside air through the air inlet pipe 8, compresses the air to form high-pressure gas, and outputs the high-pressure gas through the air outlet pipe 13, providing power for reagent atomization and delivery. Its output pressure can be adjusted by a knob 4 to suit various needs. To meet different skin testing needs, two support blocks 15 are slidably mounted on the guide rail 12. Each support block 15 has a fixing cylinder 16. Inside each fixing cylinder 16 is a liquid storage tank 10 and an atomizing tank 11, respectively. The fixing cylinder 16 is formed by two semi-circular rings joined together. When the liquid storage tank 10 or the atomizing tank 11 needs to be installed or replaced, the two semi-circular rings separate, allowing for quick placement and removal of the tanks. The air outlet pipe 13 is connected to the inside of the liquid storage tank 10. A connecting plate 17 is provided on the side of the liquid storage tank 10 that is close to the atomizing tank 11. Each connecting plate 17 has a connecting rod 22 and a fixing groove 21. The connecting rod 22 passes through the fixing groove 21 and is fitted with a locking nut to connect and fix the liquid storage tank 10 and the atomizing tank 11, ensuring a tight seal at the connection point and preventing leakage of high-pressure gas and reagents.
[0024] The electrical control box 2 is externally equipped with an adjustment knob 4 and a control switch 7. The adjustment knob 4 adjusts the compression power of the air compressor 3 to regulate the output high-pressure gas pressure, thereby meeting the atomization pressure requirements of different skin testing scenarios. The outer wall of the atomizing canister 11 is equipped with an output pipe 14. The air compressor 3 uses compressed gas pressure as power to deliver high-pressure gas to the connection between the liquid storage tank 10 and the atomizing canister 11, causing the liquid reagent in the liquid storage tank 10 to be sprayed out and atomized. The atomized reagent is regulated by the pressure of the atomizing canister 11 and output from the output pipe 14 to the test sealed chamber connected to the skin testing site, thus outputting test reagent to the skin testing site.
[0025] like Figure 1-4 As shown, in a preferred embodiment of the present invention, the side wall of the fixed cylinder 16 is provided with a connecting block 18, and the two connecting blocks 18 are respectively provided with a screw 20 and a slot 19. One end of the screw 20 passes through the slot 19 and is provided with a nut, which can realize the splicing of two semi-circular rings and improve the efficiency of installation and replacement of the liquid storage tank 10 and the atomizing tank 11.
[0026] like Figure 1-4 As shown, in a preferred embodiment of the present invention, a lead screw 24 is provided inside the guide rail 12, and a fixing nut 25 is provided on the support block 15 located below the liquid storage tank 10. The lead screw 24 passes through the fixing nut 25 and is threadedly engaged with it. One end of the lead screw 24 extends out of the guide rail 12 and is provided with a handle 23. The handle 23 drives the lead screw 24 to rotate. Since the lead screw 24 is threadedly engaged with the fixing nut 25, when the lead screw 24 rotates, it drives the fixing nut 25 to slide the liquid storage tank 10 along the guide rail 12, thereby driving the liquid storage tank 10 and the atomizing tank 11 to move closer to the air compressor 3, and finally realize the docking of the air outlet pipe 13 and the liquid storage tank 10.
[0027] like Figure 1 As shown, in a preferred embodiment of the present invention, a control box 5 is provided on the outside of the electrical control box 2, and an adjustment button 6 is provided inside the control box 5.
[0028] like Figure 1-2 As shown, in a preferred embodiment of the present invention, the air compressor 3 is provided with a filter cartridge 9, and one end of the air inlet pipe 8 is inserted into the interior of the filter cartridge 9 to filter the outside air drawn in by the air inlet pipe 8, remove dust, impurities and other harmful substances in the air, and ensure the purity of the reagents and the accuracy of the test results.
[0029] like Figure 1 As shown, in a preferred embodiment of the present invention, a flange 26 is provided on the outside of the liquid storage tank 10, and the vent pipe 13 is connected to the liquid storage tank 10 through the flange 26.
[0030] The above embodiments of the present invention provide a pressure atomization intradermal allergen delivery device. Loosening the nut on the fixing cylinder 16 and separating the two semi-circular rings, an appropriate amount of allergen test reagent is injected into the storage tank 10. After injection, the storage tank 10 is placed back into the fixing cylinder 16 to complete the fixation of the storage tank 10. The storage tank 10 and the atomizing tank 11 are fixed together by the locking nut on the connecting plate 17, ensuring a tight fit and a sealed connection. Rotating the handle 23 causes the lead screw 24 to rotate, bringing the storage tank 10 and the atomizing tank 11 closer to the air compressor 3 until the air outlet pipe 13 connects with the storage tank. 10 connects the test sealed chamber to the output pipe 14 of the atomizing canister 11 via flange 26. The test sealed chamber is fitted to the skin test site to ensure a tight seal between the chamber and the skin and prevent leakage of the atomized reagent. The air compressor 3 draws in outside air through the air inlet pipe 8, which is filtered by the filter cartridge 9 and then enters the air compressor 3. After compression, high-pressure gas is formed. The high-pressure gas is delivered to the connection between the liquid storage tank 10 and the atomizing canister 11 through the air outlet pipe 13, causing the reagent in the liquid storage tank 10 to be sprayed out and atomized. The atomized reagent is then delivered to the test sealed chamber through the output pipe 14 and applied to the skin test site to complete the allergen test.
