Description

Technical Field

[0001] The invention relates to the field of disinfection devices, and in particular to a non-contact disinfection device for sputum of patients in respiratory department. Background Art

[0002] Sputum is mucus secreted by the respiratory tract and may contain pathogens such as viruses, bacteria, and fungi, especially when individuals suffer from infectious diseases. For patients with infectious respiratory diseases (such as tuberculosis, influenza, etc.), sputum disinfection can reduce the risk of pathogens spreading to other people through air, contact or droplets. Disinfecting sputum helps maintain environmental hygiene and prevent pathogens from surviving in the environment and causing potential health problems. The methods for disinfecting sputum of respiratory patients include the following: disinfection with disinfectants, incineration, and ultraviolet disinfection, etc.

[0003] A Chinese patent with patent number CN 202020580319.7 discloses a sputum disinfection device for surgical care of patients in the Department of Respiratory Medicine. The patient spits the sputum into the feed hopper and into the containing box. High temperature heating is then used to evaporate the liquid in the sputum, taking away the virus and entering the disinfectant for treatment. However, the evaporation of the sputum liquid will cause the mucus to carry foreign matter and be adsorbed on the inside of the containing box, which is difficult to clean. It will also cause the sputum to be not handled cleanly. If the disinfectant is placed directly inside the containing box, spitting the sputum into the containing box will cause the disinfectant and sputum to splash, leading to the spread of the virus. At the same time, the sputum floats on the surface of the disinfectant, greatly affecting the disinfection effect. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1-10 As shown, a non-contact disinfection device for sputum of respiratory patients includes a disinfection barrel 1, as shown in Figure 1 As shown, in this embodiment, the sterilizing barrel 1 is set in a rectangular parallelepiped shape, which is sealed on all sides and the bottom but open on the top. The internal corners are set in an arc shape to reduce the residue of viruses and bacteria and facilitate the cleaning of the interior of the sterilizing barrel 1. A sealing cover 2 is installed on the top of the sterilizing barrel 1, and a partition plate 3 is fixedly installed inside the sterilizing barrel 1. Figure 4 As shown, the height of the partition plate 3 is lower than the height of the disinfection barrel 1, and the partition plate 3 and the disinfection barrel 1 are an integrally formed structure to ensure the stability of the structural connection. At the same time, the connection position is set to an arc surface. The partition plate 3 divides the disinfection barrel 1 into an empty area 4 and a solution area 5. The space in the solution area 5 is larger than the space in the empty area 4. Disinfectant is placed inside the solution area 5, and sputum is placed inside the empty area 4. An inclined guide plate 6 is installed inside the disinfection barrel 1. One end of the guide plate 6 is installed inside the disinfection barrel 1, and the lower surface of the other end of the guide plate 6 is against the top of the partition plate 3, and the end extends to the upper area of ​​the empty area 4. The position of the side of the guide plate 6 close to the partition plate 3 is lower than the opposite side, as shown in FIG. Figure 3 As shown, it is ensured that the liquid on the guide plate 6 falls into the interior of the vacant area 4; The solution area 5 is filled with disinfectant, and the liquid level of the disinfectant is lower than the height of the partition plate 3. A guide pipe 7 is installed on the surface of the disinfection barrel 1. Both ends of the guide pipe 7 are connected to the interior of the solution area 5, but the heights of the two ends of the guide pipe 7 are different. The liquid outlet of the guide pipe 7 is located directly above the guide plate 6, and the liquid inlet of the guide pipe 7 is located directly below the guide plate 6 and is located at the lowest point of the solution area 5. A liquid pump 8 is installed on the surface of the disinfection barrel 1. The liquid pump 8 is installed on the surface of the disinfection barrel 1. The liquid pump 8 is used to pump the disinfectant so that the disinfectant flows from the lower end of the guide pipe 7 to the upper end.

[0020] When in use, respiratory patients spit sputum onto the surface of the guide plate 6. Since there is no solution on the surface of the guide plate 6, no liquid will splash when the sputum falls, reducing the spread of viruses. Since the guide plate 6 is in an inclined state, the sputum will slide into the inside of the vacant area 4 due to its own gravity, reducing the height when falling and minimizing the possibility of solution splashing. At the same time, the liquid pump 8 is started to draw the disinfectant in the solution area 5 into the top of the guide plate 6 through the guide pipe 7. The disinfectant falls to the top of the guide plate 6 and slides along its surface. The disinfectant disinfects the guide plate 6 during the sliding process, avoiding the virus from staying on the guide plate 6 as much as possible. Finally, the disinfectant flows to the inside of the vacant area 4, and finally falls to cover the sputum. The gravitational potential energy of the disinfectant is converted into kinetic energy and smashes into the inside of the sputum, increasing the contact area between the sputum and the disinfectant, thereby improving the disinfection effect of the sputum.

[0021] The guide pipe 7 is configured as a hose, and a protective pipe 9 for support is sleeved in the middle of the guide pipe 7. Figure 2 As shown, the protective tube 9 provides protection for the guide tube 7. Fixed rods 10 are fixedly installed at both ends of the protective tube 9. One end of the fixed rod 10 is fixed to the surface of the disinfection barrel 1. When a respiratory patient uses it, he or she can lift the protective tube 9 to lift the disinfection barrel 1, thereby reducing the contact area during use.

[0022] A through slot 11 is provided on one side of the sterilizing barrel 1. Figure 4-5As shown, a mounting plate 12 is fixedly connected to the surface of the guide plate 6, and the length of the mounting plate 12 is the same as the width of the guide plate 6. The mounting plate 12 and the guide plate 6 are an integrally formed structure. The mounting plate 12 is movably mounted inside the through groove 11 through a rotating shaft 13. The rotating shaft 13 is located at the connection position between the mounting plate 12 and the guide plate 6, and the mounting plate 12 is vertically arranged upward. When the interior of the disinfection barrel 1 needs to be cleaned, the guide plate 6 needs to be rotated first to facilitate the cleaning of the empty area 4 and the solution area 5 inside the disinfection barrel 1. If the guide plate 6 is installed inside the disinfection barrel 1, there will be pits or grooves inside the disinfection barrel 1, which will make it easy for viruses and bacteria to hide inside the disinfection barrel 1 and make it difficult to clean. Therefore, the integrally formed guide plate 6 and mounting plate 12 can avoid the guide plate 6 from being installed in the disinfection barrel 1, thereby ensuring that the disinfection barrel 1 can be better cleaned.

[0023] A cavity is arranged inside the mounting plate 12, and a liquid outlet 14 is provided on one side of the mounting plate 12, the liquid outlet 14 faces the inner side of the disinfection barrel 1, and a water inlet is provided on the other side of the mounting plate 12, a connecting pipe 15 with an external thread is installed at the water inlet position, a connecting pipe 16 with an internal thread is installed at one end of the guide pipe 7, the connecting pipe 16 is threadedly sleeved on the surface of the connecting pipe 15, and the height of the connecting pipe 15 is lower than the liquid outlet 14. Liquid enters the cavity from the liquid outlet 14, accumulates inside the cavity first, and flows out from the position of the liquid outlet 14 after accumulating to a certain height, so as to prevent the disinfectant from flowing out quickly from the inside of the liquid outlet 14 and splashing inside the disinfection barrel 1.

[0024] The liquid outlet 14 is set to be a rectangular strip. The disinfectant flows out from the position of the liquid outlet 14 and can flow out evenly from the inside of the liquid outlet 14 to ensure the coverage area of ​​the disinfectant. A baffle 17 is fixedly installed inside the liquid outlet 14. The length and width of the baffle 17 are adapted to the length and width of the inside of the liquid outlet 14. The baffle 17 is close to the inner side of the liquid outlet 14. A sealing plate 19 is movably installed inside the liquid outlet 14 through a circular shaft 18. A groove 20 is opened on the side of the sealing plate 19 close to the baffle 17. The baffle 17 abuts against the inside of the groove 20. When the mounting plate 12 is rotated, due to the gravity of the sealing plate 19, the baffle 17 abuts against the inside of the groove 20. The sealing plate 19 blocks the liquid outlet 14, which can prevent the outflowing disinfectant from flowing back and polluting the inside of the cavity. When the disinfectant flows out from the position of the liquid outlet 14, the disinfectant squeezes the sealing plate 19 without affecting the outflow of the disinfectant, and can offset part of the kinetic potential energy of the outflow of the disinfectant.

[0025] An ultraviolet lamp 21 is fixedly installed on the lower surface of the sealing cover 2. The ultraviolet lamp 21 cooperates with the disinfectant to perform secondary disinfection to improve the disinfection effect. The internal circuit of the sealing cover 2 is provided to power the ultraviolet lamp 21. When the sealing cover 2 is closed, its switch can be turned on. The ultraviolet lamp 21 is located inside the disinfection barrel 1. A cover top 22 is fixedly installed on the top of the sealing cover 2 to facilitate picking up the sealing cover 2. An inner groove 23 is provided on the top of the inner wall of the disinfection barrel 1. The connection position between the inner groove 23 and the disinfection barrel 1 is set to an arc shape to reduce the hiding of viruses and bacteria. A protrusion 24 is provided on the lower surface of the sealing cover 2, and the protrusion 24 is stuck in the inner groove 23.

[0026] The sealing cover 2 includes a fixed cover 25 and a movable cover 26. Figure 7-8 As shown, the ultraviolet lamp 21 is installed below the fixed cover 25, the movable cover 26 is set to a "convex" shape, the fixed cover 25 is set to a "concave" shape, the movable cover 26 is movably installed with the fixed cover 25 through a fixed shaft 27, the fixed cover 25 and the movable cover 26 are set on the top of the disinfection barrel 1 through an installation component, and when respiratory patients use it, they only need to open the movable cover 26.

[0027] A support plate 28 is fixedly installed on the lower surface of the fixed cover 25, and the support plate 28 and the fixed cover 25 are an integrally formed structure. The support plate 28 is to ensure that when the sealing cover 2 is picked up, the fixed cover 25 or the movable cover 26 rotates, but the movable cover 26 can be rotated and opened toward the position of the disinfection barrel 1. A card slot 29 is provided on the lower surface of the movable cover 26, and the support plate 28 abuts against the inside of the card slot 29. A contact sensor 34 is fixedly installed on the upper surface of the support plate 28, and the contact sensor 34 abuts against the inside of the card slot 29. When the movable cover 26 is opened, the contact sensor 34 no longer works, and the ultraviolet lamp 21 is in a turned-off state.

[0028] When the sealing cover 2 is closed, the ultraviolet lamp 21 is turned on to continuously disinfect the sputum inside the disinfection barrel 1. When the respiratory patient needs to spit, the movable cover 26 is rotated and opened, and the contact sensor 34 is no longer against the internal ultraviolet lamp 21 of the card slot 29, and the ultraviolet lamp 21 is turned off, which will not cause harm to the patient. After the patient finishes spitting, the movable cover 26 is closed again, and the ultraviolet lamp 21 is re-lit to continuously disinfect the sputum. When the inside of the disinfection barrel 1 is disinfected, the entire sealing cover 2 can be completely taken out. During the period when the patient spits, there is no need to repeatedly pick up the entire sealing cover 2, which is more convenient and labor-saving.

[0029] like Figure 9-10As shown, the installation assembly includes three first magnetic strips 30, and the first magnetic strips 30 are embedded in the interior of the fixed cover 25. Three second magnetic strips 31 are embedded in the corresponding positions on the top of the disinfection barrel 1. The first magnetic strips 30 are adsorbed and connected with the second magnetic strips 31 to ensure that the fixed cover 25 is stably adsorbed on the surface of the disinfection barrel 1. The movable cover 26 is embedded with a first magnetic block 32, and the surface of the mounting plate 12 is embedded with a second magnetic block 33. The first magnetic block 32 is adsorbed and connected with the second magnetic block 33. The suction force of the three first magnetic strips 30 and the second magnetic strips 31 is greater than the suction force of the first magnetic block 32 and the second magnetic block 33, ensuring that when the movable cover 26 is rotated to open, it will not drive the rotation of the fixed cover 25, but the first magnetic block 32 and the second magnetic block 33 can still ensure the sealing of the movable cover 26 and ensure the sealing performance, and at the same time will not affect the opening and closing of the entire sealing cover 2.

[0030] It should be noted that the present invention is a non-contact disinfection device for sputum of respiratory patients. When in use, the sealing cover 2 is installed inside the disinfection barrel 1. When the respiratory patient needs to spit, the movable cover 26 is rotated to open, the contact sensor 34 is no longer against the internal ultraviolet lamp 21 of the card slot 29, and the sputum is spit onto the surface of the guide plate 6. Since the guide plate 6 is in an inclined state, the sputum will slide into the inside of the vacant area 4 due to its own gravity. At the same time, the liquid pump 8 is started, and the liquid enters the inside of the cavity from the liquid outlet 14. First, in the inside of the cavity, the sputum is The sputum accumulates to a certain height and flows out from the liquid outlet 14. The disinfectant squeezes the sealing plate 19 without affecting the outflow of the disinfectant, and can offset part of the kinetic potential energy of the outflow of the disinfectant. The disinfectant falls to the top of the guide plate 6 and slides along its surface. The disinfectant disinfects the guide plate 6 during the sliding process, and finally flows to the inside of the vacant area 4, and finally falls to cover the sputum. After the patient finishes spitting, the movable cover 26 is closed, and the ultraviolet lamp 21 is re-lit to continuously disinfect the sputum, thereby ensuring a better disinfection effect.
