Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular is an equipment disinfection device for anesthesia department. Background Art

[0002] The Department of Anesthesiology requires a large number of surgical instruments during surgery, and after the surgery, non-disposable anesthesia instruments and surgical tools need to be cleaned and disinfected for next use. Anesthesia instruments may be contaminated by bacteria and viruses during use, thereby increasing the risk of postoperative infection in patients. Therefore, comprehensive disinfection of anesthesia equipment is an important part of ensuring the success of surgery and patient safety. Anesthesia instruments need to be soaked and disinfected in solutions such as alcohol and hydrogen peroxide to ensure that bacteria and viruses on anesthesia instruments can be effectively removed.

[0003] In the prior art, for example, patent publication number CN110935704B discloses a portable disinfection device for the anesthesia department, and the atomization disinfection device sprays a disinfection spray to disinfect the anesthesia equipment. Patent publication number CN116585510A discloses an equipment disinfection device for the anesthesia department, which can spin dry the disinfected anesthesia equipment to facilitate direct access by medical staff. However, the equipment in the anesthesia department is different from that in other departments. In addition to the possibility of bacteria and viruses being attached after use, there may also be residual anesthetic waste gas in its pipes and gaps. The discharge of anesthetic waste gas into the atmosphere will pollute the environment and destroy the ecological balance. At the same time, medical staff will inhale the residual anesthetic waste gas when performing disinfection operations. Long-term contact may cause headaches, dizziness, nausea and other symptoms to medical staff. Therefore, the residual anesthetic waste gas needs to be processed during disinfection to reduce the harm caused by the residual anesthetic waste gas. Summary of the invention

[0004] In order to solve the above-mentioned problems, the purpose of the present invention is to provide an equipment disinfection device for anesthesia department, which can integrate waste gas treatment, use the air inhaled into the operating room to drive the disinfectant atomization, draw out the residual anesthetic waste gas in the anesthesia equipment, and purify the air in the operating room.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an equipment disinfection device for anesthesia department, comprising a box body, a disinfection chamber is provided in the box body, a disinfectant storage tank is provided on the top of the disinfection chamber, the disinfectant storage tank is connected to a release pipe for releasing the disinfectant, an airflow inlet is provided on one side of the box body, and an airflow driving component is provided at the airflow inlet;

[0006] A disinfectant spray release assembly is provided in the disinfection chamber, and the disinfectant spray release assembly is used to drive the disinfectant to form a spiral turbulent spray in the disinfection chamber through airflow;

[0007] The disinfection chamber is connected to an anesthetic waste gas processor, the bottom of the disinfection chamber is connected to a disinfectant collection component, and a sealing door is provided on one side of the box.

[0008] The following beneficial effects are achieved by adopting the above scheme:

[0009] The air intake port is connected to the operating room and can replace the operating room air purifier to respectively disinfect the operating room and remove the anesthetic waste gas generated during the anesthesia operation.

[0010] The airflow drive component can absorb the airflow in the operating room and generate an airflow of a certain speed. When the airflow passes through the disinfectant spray release component, based on the Bernoulli principle, the airflow will attract the disinfectant to mix into the airflow, thereby forming water mist beads, which are then processed to form spiral turbulent spray. In the process of the disinfectant mixing into the airflow, the disinfectant can be fully contacted with the air, thereby effectively eliminating bacteria and viruses floating in the air.

[0011] After the spiral turbulent spray is sprayed into the disinfection chamber, it will contact the equipment, and the disinfection mist beads can evenly contact the equipment, and penetrate into the pipes and gaps with the spiral turbulence for disinfection. At the same time, the spiral turbulence will affect the residual anesthetic waste gas in the equipment, so that the anesthetic waste gas is released into the airflow, thereby facilitating the harmless release of the anesthetic waste gas, and based on the waste gas treatment system, the anesthetic waste gas in the operating room and the residual anesthetic waste gas in the equipment are treated together.

[0012] Compared with the prior art, the operating room air purifier is integrated with the instrument disinfection, and the kinetic energy of the airflow drive component is fully utilized, so that the airflow drive component is not only the inhalation power source for air purification, but also uses high-speed airflow to generate spiral turbulent spray, which can make the disinfection mist beads fully contact with the air to achieve efficient air purification, generate disinfection mist beads to evenly disinfect the equipment, and use spiral turbulence to enhance the permeability of the disinfection mist beads and drive the release of residual anesthetic waste gas in the equipment. The anesthetic waste gas processor is then used to treat the anesthetic waste gas in the operating room and the residual anesthetic waste gas in the equipment at one time, increasing the utilization efficiency of the anesthetic waste gas processor and reducing the user's contact with the anesthetic waste gas during the disinfection process.

[0013] Furthermore, the disinfectant spray release component includes an air pipe, one end of which is connected to the airflow drive component, the other end of which is connected to the disinfection chamber, the middle section of the air pipe is connected to the release pipe, and a cyclone is provided at one end of the air pipe connected to the disinfection chamber.

[0014] Beneficial effects: The airflow generated by the airflow drive component will pass through the trachea and generate high-speed airflow in the trachea. The airflow attracts the disinfectant into the airflow through the Bernoulli principle and generates a rotating airflow through the cyclone for spray release.

[0015] Furthermore, a liquid separation screen is provided at one end of the air pipe close to the disinfection chamber.

[0016] Beneficial effect: The liquid separation screen can refine the disinfection mist beads, making them finer and more uniform.

[0017] Furthermore, a controller is provided in the box, an electrically controlled universal joint is provided on the top of the disinfection chamber, the end of the air pipe close to the disinfection chamber is made of flexible material, the electrically controlled universal joint is fixedly connected to the air pipe, and the electrically controlled universal joint is used to control the release direction of the disinfectant spray.

[0018] Beneficial effect: The controller controls the universal joint through a preset program, so that the universal joint controls the air pipe to spray spiral turbulent spray in all directions, so that the contact effect of the disinfection mist beads is better and the penetration effect is stronger.

[0019] Furthermore, an air flow turbulent device is fixedly connected to the side wall of the disinfection chamber.

[0020] Beneficial effect: The air turbulence device can provide turbulence effects in other directions, so that the sprayed spiral turbulent spray can better penetrate into the equipment.

[0021] Furthermore, a drying chamber is provided in the box body, which is located at the bottom of the disinfection chamber. The drying chamber and the disinfection chamber are separated by a partition, and a swing door is provided on the partition. A lifting platform is provided at the bottom of the drying chamber. The position of the lifting platform corresponds to the swing door, and the diameter of the lifting platform is the same as the opening diameter of the swing door.

[0022] Beneficial effect: After the disinfection is completed, the lifting platform carrying the equipment is lowered, and the door is swung open and closed. The disinfection spray will not enter the drying chamber, allowing the equipment to be dried for subsequent processing.

[0023] Furthermore, a hollow placement rack is provided on the lifting platform.

[0024] Beneficial effect: If the bottom of the equipment is placed in contact with the lifting platform, it will be difficult for the bottom to contact the disinfection mist beads, resulting in poor disinfection effect on this surface. Through the hollow placement rack, the disinfection mist beads can contact the bottom surface of the disinfection equipment under the action of turbulence, thereby improving the disinfection rate.

[0025] Furthermore, a heater is provided in the drying chamber, and the drying chamber is connected to the anesthetic waste gas processor.

[0026] Beneficial effect: The heater can heat the drying chamber, thereby accelerating the evaporation of the disinfectant and shortening the disinfection time. Since the air in the operating room also contains anesthetic waste gas, but the content is lower after being diluted by the air, after the equipment is sent into the drying chamber, there will also be anesthetic waste gas in the drying chamber, so it needs to be connected to the anesthetic waste gas processor for treatment.

[0027] Furthermore, an ultraviolet disinfection lamp is provided in the drying chamber, and a diffuse reflection plate is provided at the bottom of the drying chamber.

[0028] Beneficial effects: Since the air in the operating room is used as the driving force, the air in the operating room will be continuously released, which may cause bacteria that have not been completely disinfected to remain on the equipment. Although the remaining disinfectant on the equipment will continue to work, and the heater can also perform disinfection, adding an ultraviolet disinfection lamp can further increase the disinfection speed, and the diffuse reflection plate can reflect ultraviolet rays to the bottom of the equipment, which can enhance the disinfection effect on the bottom of the equipment.

[0029] Furthermore, the lifting platform is provided with a rotary driving member, and the rotary driving member is used to drive the lifting platform to rotate.

[0030] Beneficial effect: The rotating drive can drive the lifting platform to rotate, so that all surfaces of the equipment can be disinfected more evenly and comprehensively.

[0031] Furthermore, the anesthetic waste gas processor includes a processing chamber, in which an absorption liquid is arranged, an air inlet pipe is arranged at the bottom of the processing chamber, the air inlet pipe is connected to the disinfection chamber and the drying chamber respectively, and a plurality of one-way air valves are arranged in the air inlet pipe.

[0032] Beneficial effects: The anesthetic waste gas processor uses an absorbent liquid for treatment, which can absorb the anesthetic waste gas based on a chemical reaction to achieve green treatment of the anesthetic waste gas. The heat in the drying chamber is also transferred to the treatment chamber through the airflow, increasing the temperature of the treatment chamber, thereby increasing the chemical reaction rate and the processing speed.

[0033] Furthermore, the disinfectant collection assembly includes a collection box, which is connected to the bottom of the disinfection chamber. The bottom of the disinfection chamber is provided with a plurality of guide grooves leading to the collection box.

[0034] Beneficial effect: With the continuous spraying of the spiral turbulent spray, the spiral turbulent spray will condense on the surface of the equipment, and finally drip into the guide groove and gather into the disinfection chamber for collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is further described in detail through specific implementation methods:

[0042] The figure marks in the drawings of the specification include: box body 1, disinfection chamber 2, disinfectant storage box 3, release tube 4, air flow suction port 5, air flow drive assembly 6, air pipe 7, cyclone 8, liquid separation screen 9, electric control universal joint 10, air flow turbulent device 11, drying chamber 12, partition 13, swing door 14, lifting platform 15, placement rack 16, heater 17, ultraviolet disinfection lamp 18, diffuse reflection plate 19, rotating drive member 20, processing chamber 21, absorption liquid 22, air inlet pipe 23, collection box 24, guide groove 25, sealing door 26.

[0043] The embodiment is basically as shown in the attached Figure 1 To Attachment Figure 6 As shown:

[0044] A device for disinfecting equipment used in anesthesia department comprises a box body 1, a sealing door 26 is provided on one side of the box body 1, a disinfection chamber 2 is provided in the box body 1, a disinfectant storage tank 3 is fixed to the top of the disinfection chamber 2 by screws, the disinfectant storage tank 3 is connected to a release pipe 4 for releasing the disinfectant, a flow valve is installed in the release pipe 4 for release control, an airflow inlet 5 is opened on one side of the box body 1, an airflow drive component 6 is fixed to the airflow inlet 5 by screws, and the airflow drive component 6 is an air pump.

[0045] The air inlet 5 is located in the operating room and can replace the operating room air purifier to disinfect the operating room and remove the anesthetic waste gas generated during the anesthesia operation. Since the anesthesia equipment is disinfected after use, it can be integrated near the operating room to treat the anesthetic waste gas in the operating room after the anesthesia is completed, and at the same time reduce the user's moving distance. Even if the residual anesthetic waste gas in the anesthesia equipment is released during transportation, it can be treated by air purification.

[0046] A disinfectant spray release assembly is provided in the disinfection chamber 2, and the disinfectant spray release assembly includes an air pipe 7, one end of the air pipe 7 is connected to the airflow drive assembly 6, the other end of the air pipe 7 is connected to the disinfection chamber 2, the middle section of the air pipe 7 is connected to the release pipe 4, and a cyclone 8 is installed at one end of the air pipe 7 connected to the disinfection chamber 2.

[0047] The airflow generated by the airflow drive component 6 will pass through the trachea 7, and generate an airflow of a certain speed in the trachea 7. When the airflow passes through the disinfectant spray release component, based on the Bernoulli principle, the airflow will attract the disinfectant to mix into the airflow, thereby forming water mist beads, which are then processed by the cyclone 8 to form spiral turbulent spray. In the process of the disinfectant mixing into the airflow, the disinfectant can be fully contacted with the air, thereby effectively eliminating the bacteria and viruses floating in the air. After the spiral turbulent spray is sprayed into the disinfection chamber 2, the spiral turbulent spray will contact the equipment, and the disinfectant mist beads can evenly contact the equipment, and penetrate into the pipeline and the gap with the spiral turbulence for disinfection. At the same time, the spiral turbulence will affect the residual anesthetic waste gas in the equipment, so that the anesthetic waste gas is released into the airflow, so as to facilitate the harmless release of the anesthetic waste gas, and the anesthetic waste gas in the operating room and the residual anesthetic waste gas in the equipment are processed together based on the waste gas treatment system.

[0048] One end of the air pipe 7 close to the disinfection chamber 2 is provided with a liquid separation screen 9. The liquid separation screen 9 can refine the disinfection mist beads to make the disinfection mist beads finer and more uniform.

[0049] A controller is installed in the box 1, an electrically controlled universal joint 10 is fixed with screws on the top of the disinfection chamber 2, the end of the trachea 7 close to the disinfection chamber 2 is made of flexible material, the electrically controlled universal joint 10 is bonded and fixed to the trachea 7, and the electrically controlled universal joint 10 is used to control the release direction of the disinfectant spray.

[0050] The controller controls the electric-controlled universal joint 10 through a preset program, so that the electric-controlled universal joint 10 controls the air pipe 7 to spray spiral turbulent spray in all directions, so that the contact range of the disinfection mist beads is expanded, the effect is better, and the penetration effect is stronger.

[0051] An air flow turbulator 11 is bolted to the side wall of the disinfection chamber 2, and the air flow turbulator 11 is a fan.

[0052] The air turbulence device 11 can provide turbulence effects in other directions. In this embodiment, it can generate swirl in the vertical direction, so that the sprayed spiral turbulence spray can better penetrate into the equipment. The electric control universal joint 10 compensates for the deviation of the disinfectant caused by the wind force of the air turbulence device 11 by adjusting the angular surplus of the disinfection release.

[0053] A drying chamber 12 is also provided in the box body 1. The drying chamber 12 is located below the disinfection chamber 2. The drying chamber 12 is separated from the disinfection chamber 2 by a partition 13. The partition is fixed to the box body with screws. A swing door 14 is provided on the partition 13. A lifting platform 15 is provided at the bottom of the drying chamber 12. The position of the lifting platform 15 corresponds to the swing door 14. The diameter of the lifting platform 15 is the same as the opening diameter of the swing door 14. The lifting platform is driven to rise and fall by a cylinder. A hollow placement rack 16 is provided on the lifting platform 15. A rotating drive member 20 is installed at the bottom of the lifting platform 15. The rotating drive member 20 is a motor. The rotating drive member 20 is used to drive the lifting platform 15 to rotate.

[0054] When disinfecting, open the sealed door 26, and place the equipment on the hollowed-out placement rack 16. Since the placement rack 16 is provided with a hollowed-out structure, the disinfection mist beads can enter from the hollowed-out part of the placement rack 16. The air flow turbulence device 11 will generate turbulence in the vertical direction. When the disinfection mist beads enter from the hollowed-out part of the placement rack 16, the turbulence in the vertical direction will cause the disinfection mist beads to produce vertical fluctuations, contact and adhere to the bottom of the equipment, disinfect the bottom of the equipment, and improve the disinfection coverage rate. After the disinfection is completed, the lifting platform 15 is lowered with the equipment, and the swing door 14 is closed. The disinfection spray will no longer enter the drying chamber 12, and the equipment can be dried for subsequent processing. After the drying is completed, open the sealed door 26, take out the equipment, the controller will control the swing door 14 to open, and the lifting platform 15 will rise to support the opening of the swing door 14 to prevent the disinfectant from penetrating into the drying chamber 12.

[0055] The sealed door 26 is provided with separate opening doors for the disinfection chamber 2 and the drying chamber 12, respectively, so as to reduce the secondary contamination of the drying chamber 12 after the sealed door 26 is opened. A Hall sensor is integrated on the opening door of the disinfection chamber 2, which can detect the opening and closing state of the opening door of the disinfection chamber 2. When the opening door of the disinfection chamber 2 is opened or the lifting platform is started, the airflow pumping of the airflow drive component 6 and the release of the disinfectant are suspended to prevent the user from getting his hands wet when placing the equipment and to prevent too many disinfection mist beads from entering the drying chamber.

[0056] A heater 17 is screwed in the drying chamber 12, and the drying chamber 12 is connected to the anesthetic waste gas processor. The anesthetic waste gas processor includes a processing chamber 21, in which an absorption liquid 22 is arranged, and an air inlet pipe 23 is arranged at the bottom of the processing chamber 21, and the air inlet pipe 23 is respectively connected to the disinfection chamber 2 and the drying chamber 12, and a plurality of one-way air valves are installed in the air inlet pipe 23, and the one-way air valves are respectively distributed at the connection with the disinfection chamber 2, the connection with the drying chamber 12, and the connection between the air inlet pipe 23 and the processing chamber 21.

[0057] An ultraviolet disinfection lamp 18 is screwed into the drying chamber 12 , and a diffuse reflection plate 19 is integrally formed at the bottom of the drying chamber 12 .

[0058] The heater 17 can heat the drying chamber 12, thereby accelerating the evaporation rate of the disinfectant and shortening the disinfection time. Since the air in the operating room also contains anesthetic waste gas, but the content is low after being diluted by the air, after the equipment is sent into the drying chamber 12, there will also be anesthetic waste gas in the drying chamber 12, so it is necessary to connect with the anesthetic waste gas processor to treat it. Since the air in the operating room is used as the drive, the air in the operating room will continue to be released, which may cause bacteria that are not completely disinfected to remain on the equipment. Although the disinfectant remaining on the instrument will continue to work, and the heater 17 can also be disinfected, adding an ultraviolet disinfection lamp 18 can further increase the disinfection speed, and the diffuse reflection plate 19 can reflect ultraviolet rays to the bottom of the equipment, which can enhance the disinfection effect on the bottom of the equipment. The anesthetic waste gas processor uses an absorbent 22 for treatment, and the absorbent 22 can absorb the anesthetic waste gas based on a chemical reaction to achieve green treatment of anesthetic waste gas. The heat in the drying chamber 12 will also be transferred to the processing chamber 21 through the airflow, increasing the temperature of the processing chamber 21, thereby increasing the chemical reaction rate and the processing speed.

[0059] The disinfectant collection assembly includes a collection box 24, which is connected to the bottom of the disinfection chamber 2. The bottom of the disinfection chamber 2 is provided with a plurality of guide grooves 25 leading to the collection box 24. With the continuous spraying of the spiral turbulent spray, the spiral turbulent spray will condense on the surface of the equipment, and finally drip into the guide grooves 25 and gather in the disinfection chamber 2 for collection, so as to prevent the disinfectant from pouring into the drying chamber 12 after the lifting platform 15 is lowered, causing the humidity in the drying chamber 12 to be too high.
