Description

Technical Field

[0001] The present invention relates to the technical field of disinfection devices, and in particular to a disinfection device for biomedical preparation based on high-temperature steam. Background Art

[0002] In the field of biopharmaceutical preparation, a sterile environment is of vital importance. Traditional disinfection methods, such as chemical disinfection, are prone to leaving harmful residues, affecting the quality of drugs. Although dry heat disinfection can kill some microorganisms, it is not very effective for instruments with complex structures. High-temperature steam disinfection has become the mainstream method because it can use high temperature to destroy microbial cell structure and protein. However, existing high-temperature steam disinfection devices for biopharmaceutical preparation have problems such as uneven steam distribution and condensate accumulation that affects the disinfection effect, and they are in urgent need of improvement.

[0003] The existing Chinese patent with announcement number CN118059274B discloses an automatic disinfection device based on the recycling of fiber fabrics. This invention uses the combination of multiple disinfection methods to achieve continuous dynamic disinfection of fabrics by using the coordination of the overall part and the independent part, and can complete the coherent and efficient disinfection of multiple areas and multiple fabrics in a single area at a single time. At the same time, during the exchange of different disinfection methods, the fabrics are kept in a non-absorption saturated state for disinfection, and then the fabrics are quickly and fully disinfected, ensuring that a single disinfection method can achieve an effective effect on the fabric while improving the overall disinfection effect of the fabrics implemented by the coordination of multiple disinfection methods.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the steam injection of existing disinfection devices mostly adopts unilateral or local single-point injection, which leads to uneven steam distribution and the existence of blind spots in disinfection.

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0020] Reference Figure 1-Figure 5 As shown, the present invention provides a technical solution: a high-temperature steam-based biomedical preparation disinfection device, comprising a disinfection box 1, a side box 11 fixedly mounted on one side of the disinfection box 1, a disinfection tube 12 provided inside the disinfection box 1, a steam output component 3 for air supply provided inside the disinfection tube 12, a storage component 4 for placing medicines provided inside the disinfection tube 12, a driving component 2 provided inside the side box 11, and a guide component 5 for controlling airflow recoil provided inside the storage component 4; The storage component 4 includes a mounting ring 41 arranged inside the disinfection tube 12, and the inner wall of the mounting ring 41 is fixedly connected to the inner plate 42, and the surface of the inner plate 42 is provided with a mounting groove, and a hollow box 43 for containing medicine is provided inside the mounting groove. The inner wall of the mounting ring 41 is also fixedly connected to the chassis 45, and a ventilation groove is formed between the inner plate 42 and the chassis 45 and is connected to the mounting groove corresponding to the hollow box 43. A support ring 44 is fixedly connected to the upper surface of the chassis 45, and the support ring 44 is arranged corresponding to the hollow box 43. A first ventilation groove 422 is provided in the center of the upper surface of the inner plate 42 and the chassis 45. During the disinfection process, high-temperature steam enters the disinfection box 1 from the top of the disinfection box 1 to perform high-temperature disinfection on the medicine inside the hollow box 43. The high-temperature steam can continue to flow downward through the first ventilation groove 422 and the mounting groove, wherein the support ring 44 supports the hollow box 43 from the bottom.

[0021] Reference Figures 1-9As shown, in this embodiment: the guide component 5 includes a long rod 54 rotatably connected to the inside of the chassis 45, one end of the long rod 54 is fixedly connected to a conical shell 55, and the conical shell 55 is arranged corresponding to the first ventilation groove 422, and the other end of the long rod 54 is fixedly connected to an internal gear 53, the inner wall of the disinfection tube 12 is fixedly connected to a connecting ring 47, the inner wall of the connecting ring 47 is fixedly connected to a connecting block 51, and the upper surface of the connecting block 51 is fixedly connected to a rack plate 52, and the rack plate 52 is meshed with the internal gear 53. In the process of steam being discharged downward, part of the steam is discharged downward through the first ventilation groove 422, and the steam airflow entering the first ventilation groove 422 is discharged to the inside of the surrounding ventilation grooves under the guidance of the conical shell 55, and is discharged in the opposite direction from the mounting groove under the guidance of the support ring 44, and the medicine in the hollow box 43 is recoiled, thereby enhancing the air flow turbulence and steam permeability.

[0022] The driving component 2 includes a motor 21 arranged inside the side box 11, and the output end of the motor 21 is fixedly connected to the rotating shaft 22, and the outer side of the rotating shaft 22 is fixedly connected to the driving gear 23. The outer side of the mounting ring 41 is fixedly connected to the outer gear ring 24, and the outer gear ring 24 is meshed with the driving gear 23. During the disinfection process, the rotating shaft 22 and the driving gear 23 are driven to rotate by the motor 21, thereby driving the outer gear ring 24 to rotate, and the mounting ring 41 rotates accordingly, allowing the steam airflow above to be evenly injected into the hollow box 43 from multiple directions. During the rotation process, the inner gear 53 moves and meshes with the rack plate 52, thereby driving the inner gear 53 to rotate half a circle, thereby realizing the flipping of the conical shell 55. When the conical shell 55 is flipped, the airflow is discharged through the conical shell 55 at this time, and is gathered and discharged, thereby enhancing the airflow.

[0023] There are two groups of storage parts 4 and driving gears 23. The two groups of storage parts 4 and driving gears 23 are distributed vertically, and the driving gears 23 are arranged corresponding to the storage parts 4. A second ventilation groove 421 is provided on the upper surface of the inner disk 42. The second ventilation groove 421 arranged at the top is arranged corresponding to the hollow box 43 arranged at the bottom. The two groups of conical shells 55 are in opposite rotation states. In the process of downward discharge of steam airflow, air can be blown to the hollow box 43 below through the second ventilation groove 421 to ensure the disinfection effect. At the same time, the two groups of conical shells 55 are always in opposite rotation states, so that when the airflow discharged from the upper conical shell 55 is enhanced, the corresponding steam airflow rushes to the surface of the conical shell 55, thereby spreading to the surroundings for recoil.

[0024] A cubic block 531 is fixedly connected to one side of the internal gear 53, and a slide groove 451 is provided on the inner wall of the chassis 45. The cubic block 531 is slidably connected to the inside of the slide groove 451. A flip groove 452 is also provided on the inner wall of the slide groove 451. The flip groove 452 is arranged corresponding to the connecting block 51. During the normal rotation of the mounting ring 41, the cubic block 531 always slides inside the slide groove 451, which has a limiting effect and prevents the conical shell 55 from flipping. When the internal gear 53 contacts the rack plate 52, the cubic block 531 flips in the flip groove 452, and then enters the slide groove 451 again and continues to slide.

[0025] A short rod 56 is fixedly connected to the side of the conical shell 55 opposite to the long rod 54. The short rod 56 is rotatably connected to the inside of the chassis 45. The arrangement of the short rod 56 further ensures the stability of the conical shell 55 when flipping.

[0026] A drainage groove 46 is provided on the upper surface of the chassis 45, and the drainage groove 46 is arranged inside the support ring 44. A guide ring 471 is fixedly connected to one side of the connecting block 51. The guide ring 471 is arranged corresponding to the bottom opening of the drainage groove 46. The guide ring 471 is a circular ring with a flared bottom. When the air flow enters the ventilation groove and is discharged to the support ring 44, the condensed water inside the ventilation groove is blown toward the drainage groove 46. When the drainage groove 46 is closed and the chassis 45 rotates due to centrifugal force, the condensed water is discharged through the drainage groove 46 and discharged to the surrounding areas under the guidance of the connecting ring 47, thereby preventing the condensed water from dripping directly downwards and affecting the disinfection of drugs.

[0027] A sealing groove 411 is provided on the upper surface of the mounting ring 41 , and the sealing groove 411 is slidably connected to the disinfection tube 12 . Through the setting of the sealing groove 411 , the sealing effect is ensured while ensuring the normal sliding of the mounting ring 41 .

[0028] The steam output component 3 includes an air supply pipe 31 fixedly connected to one side of the disinfection box 1. One end of the air supply pipe 31 passes through the disinfection box 1 and the disinfection tube 12 and is fixedly connected to an air supply ring 32. An air supply ring 32 is fixedly installed on the bottom of the air supply ring 32. An injection pipe 33 is fixedly connected to the bottom of the air supply ring 32. An exhaust pipe and a safety valve are provided at the bottom of the disinfection box 1. High-temperature steam is ejected downward from the air supply ring 32 and the injection pipe 33 through the air supply pipe 31, providing downward-moving high-temperature steam for disinfection.

[0029] A drainage component 6 for discharging condensed water is provided at the bottom of the disinfection tube 12. The drainage component 6 includes a concave drainage tray 61 fixedly connected to the bottom surface of the disinfection tube 12. A drainage pipe 62 is fixedly connected to the bottom surface of the concave drainage tray 61. A drain valve 63 is provided inside the drain pipe 62. The arrangement of the concave drainage tray 61, the drain pipe 62 and the drain valve 63 facilitates the discharge of condensed water.

[0030] Working principle: Before the disinfection work, the medicine is placed inside 43. After closing 1, the external steam generator is turned on, and high-temperature steam is ejected downward from the air delivery ring 32 and the air jet pipe 33 through the air delivery pipe 31 to perform high-temperature disinfection on the medicine inside the hollow box 43. The high-temperature steam can continue to flow downward through the first ventilation groove 422, the second ventilation groove 421 and the installation groove. Part of the steam passes between the first ventilation groove 422 and enters the first ventilation groove 422. The steam airflow is discharged to the inside of the ventilation grooves around it under the guidance of the conical shell 55. Under the guidance of the support ring 44, it is discharged from the installation groove in the opposite direction to recoil the medicine in the hollow box 43, thereby enhancing the airflow turbulence and steam penetration. In addition, during the disinfection process, the motor 21 drives the rotating shaft 22 and the driving gear 23 to rotate, thereby driving the outer gear ring 24 to rotate, and the mounting ring 41 rotates accordingly, allowing the steam airflow above to be evenly injected into the hollow box 43 from multiple directions. During the rotation process, the inner gear 53 moves to engage with the rack plate 52, thereby driving the inner gear 53 to rotate half a circle, thereby realizing the flipping of the conical shell 55. When the conical shell 55 is flipped, when the airflow is discharged through the conical shell 55 at this time, the airflow is concentrated and discharged to enhance the airflow. When the airflow discharged from the upper conical shell 55 is enhanced, the corresponding steam airflow rushes to the surface of the conical shell 55, thereby diffusing to the surroundings for recoil, thereby ensuring the recoil effect of the airflow below. Among them, when the air flow enters the ventilation groove and is discharged toward the support ring 44, the condensed water inside the ventilation groove is blown toward the drain groove 46. Under the action of the closure of the drain groove 46 and the centrifugal force of the rotation of the chassis 45, the condensed water is discharged through the drain groove 46 and discharged to the surroundings under the guidance of the connecting ring 47, thereby preventing the condensed water from dripping directly downward and affecting the disinfection of the medicine. Through the setting of the concave drain pan 61, the drain pipe 62 and the drain valve 63, the condensed water is finally discharged to prevent excessive condensed water from remaining, resulting in poor temperature uniformity.

[0031] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
