[0002] The subcutaneous electronic syringe control and booster device is an innovative and high-tech medical device. This device is typically composed of an electronic control system, a drive component, and a syringe assembly. Its working principle is to achieve precise regulation of the syringe injection speed, dosage, and depth through precise electronic control. In the medical field, it has many advantages. For example, in vaccination, it can ensure the accuracy and consistency of each injection dose, improving the safety and effectiveness of vaccination. In the treatment of certain chronic diseases, for example, long-term and regular subcutaneous drug injections are required. This device can automatically perform injections according to a preset program, alleviating the patient's pain and inconvenience. Some advanced subcutaneous electronic syringe control and booster devices also have intelligent functions, such as the ability to connect with mobile devices, allowing medical staff or patients to monitor the injection status and record relevant data in real time. In actual application, different models and brands of devices may vary in performance, accuracy, and ease of use. For example, some devices are suitable for large-scale vaccination scenarios and are characterized by speed and efficiency, while others are more suitable for individual home use and are more compact and portable. Overall, the subcutaneous electronic syringe control and booster device brings higher precision, convenience, and safety to injection treatment in the medical field, and has broad application prospects and development space.

[0003] During the use of the subcutaneous electronic syringe control booster device, the injection liquid of the handle follows the gas into the main air pump when in use, and the particles on the human skin will also enter the air pump through the pipeline, thereby causing damage to the air pump and affecting the service life of the air pump. In addition, the subcutaneous electronic syringe control booster device produces certain noise during use. By analyzing the noise source of the subcutaneous electronic syringe control booster device, it is found that the noise generated by the air pump is the main noise source. By analyzing the intake and exhaust principles of the air pump, the frequency of the intake noise is mainly low-frequency noise, and the frequency of the exhaust noise is mainly high-frequency noise.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] like Figures 1 to 11 As shown, the present invention provides a subcutaneous electronic syringe control booster device, comprising a trolley 1, a main unit 2, and a handle 3. The main unit 2 is mounted on the top of the trolley 1 and is connected to the handle 3 via a pipe. The handle 3 of the subcutaneous electronic syringe control booster device is an existing public technology and will not be described in detail here.

[0042] The main unit 2 includes an upper cover 21, a lower shell 22, an electrical part 23, a gas circuit part 24, and a display 25. The upper cover 21 is movably connected to the lower shell 22. The electrical part 23 and the gas circuit part 24 are both mounted on the lower shell 22. The electrical part 23 of the subcutaneous electronic syringe control booster device is an existing public technology and will not be described in detail here. The display 25 is mounted on the upper cover 21.

[0043] The air path portion 24 includes a primary filter 241, the inlet of the primary filter 241 is connected to the handle 3 through a pipe. When the handle 3 is in use, the air pump 245 can suck up the skin to facilitate the insertion of the needle into the specified depth under the skin, but it will suck away some of the injection liquid and particles on the skin. The outlet of the primary filter 241 is connected to the secondary filter 242 through a pipe, and the outlet of the secondary filter 242 is connected to the tertiary filter 243 through a pipe. The outlet of the tertiary filter 243 is connected to the air intake muffler 244 through a pipe. The air intake position of the air pump 245 is low. High-frequency noise, the outlet of the air intake silencer 244 is connected to the air pump 245 through a pipe. The air pump 245 should be connected to a power supply and a controller, etc., which will not be repeated here. The outlet of the air pump 245 is connected to the exhaust muffler 246. The exhaust position of the air pump 245 is high-frequency noise. The air inhaled into the air pump 245 is filtered at multiple stages to remove the injection liquid and particulate matter in the air to prevent the injection liquid from flowing into the air pump 245 of the main unit 2 through the gas when the handle 3 is used, or to prevent particulate matter on human skin from entering the air pump 245 through the pipe to damage the air pump 245.

[0044] Specifically, the first-stage filter 241 and the third-stage filter 243 both include a filter sleeve 2411, and a cylindrical filter screen 2412 with an opening on the top surface is provided in the filter sleeve 2411. The filter screen with a cylindrical shape and structure can increase the contact area with the air, and the air flows from the outside to the inside. When cleaning the cylindrical filter screen 2412, high-pressure gas can be passed into the cylindrical filter screen 2412 to quickly clean the dirt blocking the filter holes. The two ends of the filter sleeve 2411 are respectively threadedly connected with a filter air inlet end cover 2413 and a filter air outlet end cover 2414. The filter sleeve 2411 is threadedly connected to the filter air inlet end cover 2413 and the filter air outlet end cover 2414, which can facilitate the disassembly and assembly of the structure, whether it is cleaning the cylindrical filter screen 2412 or It is relatively convenient to replace each structure. The open end of the cylindrical filter 2412 is close to the filter outlet end cover 2414, so that the unfiltered air flows from the outside to the inside of the cylindrical filter 2412, and the filtered large-particle particles remain on the outside of the cylindrical filter 2412, which is relatively easy to clean. The filter inlet end cover 2413 and the filter outlet end cover 2414 are respectively penetrated by a filter inlet pipe 2415 and a filter outlet pipe 2416. A sealing plate 2417 is provided in the filter outlet end cover 2414. The filter outlet pipe 2416 penetrates the sealing plate 2417 and extends into the cylindrical filter 2412, so that the filtered air is discharged from the inside of the cylindrical filter 2412, and the sealing plate 2417 covers the opening position of the cylindrical filter 2412.

[0045] Furthermore, a plurality of evenly distributed positioning brackets 2418 are fixedly connected to the inner wall of the filter sleeve 2411, and the cylindrical filter screen 2412 is arranged on the positioning bracket 2418. The positioning bracket 2418 positions and supports the cylindrical filter screen 2412. The positioning bracket 2418 is provided with a plurality of equidistantly arranged air flow holes 2419 to prevent the positioning bracket 2418 from separating the space outside the cylindrical filter screen 2412, so as to facilitate air flow in the space outside the cylindrical filter screen 2412. The filter pore diameter of the cylindrical filter screen 2412 of the first-stage filter 241 is larger than the filter pore diameter of the cylindrical filter screen 2412 of the third-stage filter 243. The cylindrical filter screen 2412 of the first-stage filter 241 can filter large-sized particles, and the cylindrical filter screen 2412 of the third-stage filter 243 can intercept small-sized particles to improve the filtering effect.

[0046] Furthermore, the secondary filter 242 includes an adsorption sleeve 2421, and both ends of the adsorption sleeve 2421 are threadedly connected to adsorption end covers 2422, and the adsorption end cover 2422 is fixedly connected to an air guide tube 2423 that is arranged through it. A partition net 2424 is fixed to the inner wall of the adsorption end cover 2422 near the adsorption sleeve 2421, and the partition net 2424 restricts the activated carbon filler 2425 in the adsorption sleeve 2421. After unscrewing the adsorption end cover 2422, the activated carbon filler 2425 can be poured out to facilitate replacement of the activated carbon filler 2425. The adsorption sleeve 2421 is filled with activated carbon filler 2425, and the activated carbon can absorb debris and a small amount of injection liquid, intercepting the small amount of injection liquid carried in the air to avoid damage to the air pump 245.

[0047] It is worth noting that the air intake silencer 244 and the exhaust silencer 246 both include a silencer sleeve 2461, and the two ends of the silencer sleeve 2461 are respectively threadedly connected with a silencer air intake end cover 2462 and a silencer air outlet end cover 2463, and the silencer air intake end cover 2462 and the silencer air outlet end cover 2463 are respectively fixedly connected with a silencer air intake pipe 2464 and a silencer air outlet pipe 2465 that are set through them, and the inner wall of the silencer air outlet end cover 2463 is fixedly connected with a reflector 2466 near the silencer sleeve 2461. The sound waves hit the reflector 2466 and then reflect. The propagation directions of the two waves are exactly opposite, so the peaks and troughs of the two waves cancel each other out, thereby reducing the propagation of the waves, thereby achieving the purpose of noise reduction. The silencer air outlet pipe 2465 passes through the reflector 2466 and extends into the silencer sleeve 2461.

[0048] It is worth noting that sealing rings 2467 are provided between the silencer sleeve 2461 and the silencer air inlet end cover 2462, and between the silencer sleeve 2461 and the silencer air outlet end cover 2463. Polyurethane silencer cotton 2468 is provided in the silencer sleeve 2461 of the exhaust silencer 246. The polyurethane silencer cotton 2468 can further absorb noise. For the high-frequency noise at the exhaust position of the air pump 245, the polyurethane silencer cotton 2468 can be used to improve the effect of eliminating high-frequency noise.

[0049] It is worth mentioning that a handle bracket 4 is installed on the side of the host 2, and a non-slip silicone pad 5 is provided on the inner wall of the bottom of the handle bracket 4. After the handle 3 is placed on the handle bracket 4, the non-slip silicone pad 5 can effectively prevent the handle 3 from sliding relative to the handle bracket 4, so as to avoid the handle 3 from slipping and breaking due to carelessness during placement, which is beneficial to protecting the handle 3. Corresponding magnet adsorption plates 6 are provided on the side of the host 2 and the handle bracket 4. The handle bracket 4 is adsorbed and fixed to the side of the host 2 by the magnet adsorption plate 6, making it more convenient to fix the handle bracket 4 on the side of the host 2.

[0050] It is worth emphasizing that the top of the trolley 1 is provided with a sink 7 that matches the main unit 2. The sink 7 can limit the position of the main unit 2. A hand screw 8 is installed at the bottom of the sink 7. A screw hole 9 is provided at the position of the bottom of the main unit 2 corresponding to the hand screw 8. The screw hole 9 is threadedly connected to the hand screw 8. The screw hole 9 cooperates with the hand screw 8 to fix the main unit 2 on the trolley 1. Protective silicone pads 10 are pasted at the four corners of the bottom of the main unit 2. The protective silicone pads 10 can prevent mutual friction between the bottom end surface of the main unit 2 and the trolley 1, and prevent wear on the bottom end surface of the main unit 2. A storage box 11 is installed at the lower rear side of the trolley 1. The storage box 11 is convenient for placing some auxiliary items and medicines that need to be used.

[0051] It is worth mentioning that the electrical part 23 is connected to the pressure sensor 12 , the pump plug 13 , the handle plug 14 , the foot plug 15 , and the power plug 16 through lines.

[0052] Working principle and process: When the subcutaneous electronic syringe control booster device is used, the handle 3 is placed against the human skin to continuously inhale air. A small amount of injection liquid and particles on the human skin are inhaled into the air path part 24 along with the air. First, the inhaled air is introduced into the primary filter 241, and the primary air filter 241 is installed on the outside of the lower shell 22 to facilitate the disassembly and cleaning of the primary filter 241. The air is introduced into the internal space of the filter sleeve 2411 through the filtered air inlet pipe 2415 and is located on the outside of the cylindrical filter screen 2412. Then, the air flows to the inside of the cylindrical filter screen 2412, and the large-aperture filter holes of the cylindrical filter screen 2412 remove the large particles in the air. The small-sized particles are intercepted in the space outside the cylindrical filter 2412. Then, the air is guided out of the filter sleeve 2411 through the filter outlet pipe 2416, and then the air is introduced into the secondary filter 242, and then into the adsorption end cover 2422 after passing through the air guide pipe 2423, and then passes through the activated carbon filler 2425 in the adsorption sleeve 2421. In addition to adsorbing particles, the activated carbon filler 2425 can also adsorb a small amount of injection liquid. Then, the air is guided out of the adsorption sleeve 2421 through the air guide pipe 2423 at the other end, and then the air is introduced into the tertiary filter 243. The filter pore size of the cylindrical filter 2412 of the tertiary filter 243 is small, which can intercept small-sized particles. The outer space of the cylindrical filter 2412, and then the air leaves the three-stage filter 243 and is introduced into the air intake muffler 244. The sound waves are partially reflected back after hitting the reflector 2466. The propagation directions of the two waves are just opposite, and the peaks and troughs of the two waves cancel each other out, thereby reducing the propagation of the waves and achieving the purpose of noise reduction. Subsequently, the air passing through the air intake muffler 244 enters the air pump 245. Since the particles and injected liquid in the air are removed, the air pump 245 will not be damaged, so as to extend the service life of the air pump 245. The air leaving the air pump 245 is introduced into the exhaust muffler 246. The exhaust muffler 246 is set relative to the intake muffler 244. The polyurethane silencer cotton 2468 is installed to better eliminate the high-frequency noise at the exhaust position of the air pump 245, so as to achieve the purpose of noise reduction of the air pump 245 and reduce the impact on the working environment. The handle bracket 4 is fixed to the side position of the main unit 2 through the magnetic adsorption plate 6. The handle 3 is placed on the handle bracket 4 when not in use. The anti-slip silicone pad 5 can effectively prevent the handle 3 from sliding relative to the handle bracket 4 to avoid the handle 3 from slipping and breaking due to carelessness when placing it. The main unit 2 is placed in the sink 7 on the top of the trolley 1, and the screw hole 9 is used to cooperate with the hand screw 8 to fix the main unit 2, thereby connecting the main unit 2 and the trolley 1, facilitating the subcutaneous electronic syringe to control the overall movement of the booster device.
