Description

Technical Field

[0001] The present invention relates to the technical field of medical device disinfection and drying devices, in particular to a disinfection and drying device for an exhalation box. Background Art

[0002] A ventilator is a medical device that mechanically assists or replaces a patient's breathing, primarily used in critical care, surgical anesthesia, and respiratory failure treatment. The expiratory chamber is a key component of a ventilator, monitoring the patient's expiratory airflow, controlling inhalation and exhalation, and providing positive end-expiratory pressure. Whenever a ventilator patient is replaced, the ventilator chamber must be disinfected and dried to ensure safe and accurate use.

[0003] Currently, the disinfection of exhalation boxes relies primarily on manual labor, which consumes a significant amount of medical staff's time and is inefficient. The disinfection effect is also susceptible to human factors, resulting in unstable disinfection quality and other issues, making it unsuitable for high-volume medical scenarios. Furthermore, the disinfection and drying processes are often performed separately, with the mainstream drying methods being air drying and oven drying. This requires hospitals to be equipped with both disinfection and drying equipment, resulting in inconsistent processes, long disinfection and drying times, and a common problem of difficulty balancing efficiency and safety. Therefore, a professional solution that can both ensure disinfection quality and improve drying efficiency is urgently needed. Summary of the Invention

[0004] The object of the present invention is to provide a sterilizing and drying device for an exhalation box that can take into account both the sterilization quality and the drying efficiency of the sterilization operation.

[0005] To achieve the above-mentioned purpose, the present invention discloses a sterilizing and drying device for an exhalation box.

[0017] Figure 2 It is a side view of the disinfection and drying device in an embodiment of the present invention. DETAILED DESCRIPTION

[0018] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0019] This embodiment discloses a sterilizing and drying device for an exhalation box, which can achieve efficient sterilization of the exhalation box while quickly completing the drying operation, thereby optimizing the sterilization effect and drying efficiency. Figure 1 and Figure 2 As shown, the sterilization and drying device of the exhalation box includes: The disinfectant storage device 1, the first drying device 2 and the accommodating chamber 3, the first drying device 2 is used to provide a drying medium, and the accommodating chamber 3 is used to accommodate the exhalation box A.

[0020] The first pipe opening 4 and the second pipe opening 5 are provided on the side wall of the accommodating chamber 3 and are used to communicate with the interior of the exhalation box A in the accommodating chamber 3. The second pipe opening 5 is used to input pure water. The first pipe opening 4 is selectively connected to the first drying device 2 or the second control valve 7 via a first control valve 6. When the first pipe opening 4 is connected to the second control valve 7, the first pipe opening 4 is selectively connected to the disinfectant storage device 1 or the second pipe opening 5 via the second control valve 7. In this embodiment, the first control valve 6 and the second control valve 7 are three-way valves.

[0021] The third pipe port 8 is selectively connected to / disconnected from the accommodating chamber 3 via a third control valve 9 . The third pipe port 8 is used to discharge waste liquid in the accommodating chamber 3 .

[0022] It is worth noting that the "pure water" mentioned in this embodiment refers to water well-known in the medical field that has undergone special treatment to remove impurities, bacteria, and other microorganisms, achieving high purity standards. It can be used to clean medical equipment to avoid secondary contamination after disinfection and soaking. The "drying medium" refers to a common medium that can be used to dry the exhalation box A, such as flowing air or warm air provided by a fan, or heat energy provided by a dryer.

[0023] Compared with the prior art, the technical solution of the present invention has technical progress, which is specifically reflected in: First, regarding the disinfection process, the disinfectant storage device 1 of this device, in conjunction with the first and second control valves 6 and 7, precisely controls the disinfectant delivery process: the disinfectant is delivered to the first nozzle 4 through the second and first control valves 7 and 6, and then enters the interior of the exhalation box A through the first nozzle 4. Once the interior is filled with disinfectant, the excess disinfectant overflows from the passageway of the exhalation box A, allowing the disinfectant in the accommodating chamber 3 to completely immerse the exhalation box A. This design achieves simultaneous disinfection of the interior and exterior surfaces of the exhalation box A, eliminating potential blind spots or omissions with traditional manual disinfection. The system then automatically drains the waste liquid and switches to a cleaning program, thoroughly removing any residual disinfectant through a pure water rinse. This entire process requires no human intervention, ensuring consistent disinfection quality while significantly reducing the operator's workload.

[0024] Secondly, during the drying process, the disinfection and drying device closes the second control valve 7, activates the first drying device 2, and delivers controllable heat energy to the interior of the exhalation box A through the channel between the first drying device 2 and the first nozzle 4, thereby rapidly drying the exhalation box. This design overcomes the time-consuming drawback of traditional natural drying.

[0025] In summary, the application constructs a complete disinfection and drying processing system, which not only ensures the quality controllability of each processing link, but also greatly reduces the manual operation link, so that the whole processing process is more standardized and normalized. In practical application, the device can not only ensure to reach the strict medical disinfection standard, but also can significantly improve the turnover efficiency of the exhalation box A, solves the problem that the traditional processing method is difficult to balance in disinfection quality, drying efficiency and operation convenience, and has clinical application value.

[0026] Referring to Figure 1 and Figure 2 As shown in the figure, optionally, the first pipe 4 can be configured as a funnel-shaped interface Optionally, the disinfection and drying device for the exhalation box A of the embodiment further comprises a second drying device 10 arranged above the accommodating cavity 3, which is used to provide drying medium to dry the outer surface of the exhalation box A. In the embodiment, the heat energy of the first drying device 2 is mainly output to the inside of the exhalation box A, and the drying effect of the outer surface is difficult to completely guarantee. By additionally arranging the second drying device 10 specially for the outer surface of the exhalation box A, the drying effect can be further improved.

[0027] Optionally, the output end of the first drying device 2 and the second drying device 10 outputting the drying medium is further configured with an impurity filter screen.

[0028] Optionally, the inner wall of the disinfectant storage device 1 is further provided with a first sensor 11 for detecting the content of disinfectant in the disinfectant storage device 1. The first sensor 11 can be a liquid level sensor, a differential pressure sensor, etc. In the embodiment, the first sensor 11 is a liquid level sensor. When the disinfectant stored in the disinfectant storage device 1 reaches a predetermined liquid level, the disinfectant content can support the overall disinfection requirement of the exhalation box A, and the liquid level sensor sends a ready signal.

[0029] Optionally, the disinfection and drying device for the exhalation box A of the embodiment further comprises a buzzer 12, which is used to send a prompt when the disinfectant content detected by the first sensor 11 reaches a preset value.

[0031] Optionally, a second sensor 14 is further provided on the inner wall of the accommodating chamber 3 for detecting the content of the disinfectant in the container chamber. The second sensor 14 can be a liquid level sensor like the first sensor 11, or can be another type of sensor capable of detecting the content, such as a differential pressure sensor. The purpose of providing the second sensor 14 is to prevent excessive disinfectant in the accommodating chamber 3 from flowing back into the disinfectant storage device 1, which not only affects the disinfection process but also contaminates the disinfectant storage device 1 and the disinfectant therein.

[0032] Optionally, a position-limiting fixture 15 for fixing the exhalation box A is further provided in the accommodating chamber 3. The position-limiting fixture 15 can fix the exhalation box A and prevent the exhalation box A from floating in the accommodating chamber 3 and affecting the disinfection effect.

[0033] Optionally, a pressure reducing valve 16 is further provided between the second pipe port 5 and the second control valve 7. The pressure reducing valve 16 can change the throttling area of ​​the pure water, so that the flow rate and the kinetic energy of the pure water change, thereby achieving the effect of regulating the pressure of the pure water entering the pipeline.

[0034] Optionally, the disinfection and drying device of the exhalation box A of this embodiment further includes a controller 17 and a display screen 18. Controller 17 is used to control the on / off operation of the first control valve 6, the second control valve 7, the third control valve 9, the first drying device 2, and the second drying device 10.

The control board controls the buzzer 12 to emit a full-fill prompt sound based on this signal, the indicator light 20 turns green, and the display screen 18 shows that the disinfectant is full.

[0038] 2. The medical staff places the exhalation box A to be sterilized into the accommodating chamber 3 , connects the mouth of the exhalation box A to the first pipe opening 4 , and presses the tail of the exhalation box A against the limiting fixture 15 .

[0039] 3. First switch 19 is turned on, indicator light 20 turns red, and disinfection begins. Display screen 18 indicates that disinfection is in progress. First control valve 6 and second control valve 7 connect the passage between disinfectant storage device 1 and exhalation box A. Disinfectant flows naturally into exhalation box A due to gravity, soaking both the inside and outside of exhalation box A with disinfectant. When the disinfectant level reaches first sensor 11, second control valve 7 blocks the passage between disinfectant storage device 1 and exhalation box A, stopping the flow of disinfectant.

[0040] 4. Count down for 30 minutes. After 30 minutes, the disinfection is completed. The third control valve 9 opens, and the waste disinfectant flows out from the accommodating chamber 3 through the third control valve 9 to the third pipe opening 8. The display screen 18 shows that the disinfectant is being discharged for 3 minutes.

[0041] 5. Display screen 18 shows pure water flushing, and the second control valve 7 rotates to connect the channel between the second pipe opening 5 and the first pipe opening 4. Pure water enters the exhalation box A to flush away the disinfectant. The flushing time is 5 minutes.

[0042] 6. The second control valve 7 blocks the passage between the second pipe port 5 and the first control valve 6. The first control valve 6 connects the first drying device 2 and the first pipe port 4, allowing the liquid in the pipeline to flow into the accommodating chamber 3. At this time, the third control valve 9 is opened again, and the flushed liquid is discharged together with the liquid in the above-mentioned pipeline through the third control valve 9 and the third pipe port 8. The display screen 18 shows drainage, and the drainage lasts for 5 minutes.

[0043] 7. The display screen 18 shows that drying is in progress. The first drying device 2 and the second drying device 10 are activated to dry the inner surface and the outer surface of the exhalation box A respectively.

[0044] 8. After 60 minutes of blowing, the exhalation box A is blown dry, the disinfection and drying device stops running, the buzzer 12 emits a disinfection completion prompt sound, the indicator light 20 turns green, and the display screen 18 shows that the disinfection and drying is completed.

[0045] Depending on different needs, only the exhalation box can be dried. The specific process is as follows: Second switch 21 is turned on. First control valve 6 connects first drying device 2 and first nozzle 4. Display 18 indicates drying in progress. First drying device 2 and second drying device 10 are activated, drying the interior and exterior surfaces of exhalation box A, respectively. After 60 minutes of drying, exhalation box A is completely dry. First drying device 2 and second drying device 10 stop operating, buzzer 12 sounds a drying completion tone, indicator light 20 turns green, and display 18 indicates drying is complete.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
