Description

Technical Field

[0001] This invention relates to the field of sterilization equipment technology, specifically to a sterilization device for aseptic dressing packs. Background Technology

[0002] In the medical field, the sterilization of aseptic dressing packs is a crucial step in ensuring medical safety. Currently, ethylene oxide sterilization and pressurized steam sterilization are common methods for sterilizing aseptic dressing packs. Among these, ethylene oxide sterilization technology, due to its strong penetrating power, can sterilize medical supplies with complex structures and is widely used in the medical industry.

[0003] However, existing sterilization technologies and equipment still have many problems. While ethylene oxide sterilization is widely used, its long sterilization cycle, typically requiring several hours or even longer for a single sterilization session, makes it difficult to meet emergency needs and impacts medical efficiency. Furthermore, during the sterilization process, it is difficult to ensure that all parts of the dressing pack receive uniform sterilization, resulting in sterilization dead zones and inconsistent sterilization effects. Incomplete sterilization of some dressing packs may lead to postoperative infections and other medical risks.

[0004] Therefore, there is an urgent need to develop a new type of sterile dressing pack sterilization equipment to overcome the shortcomings of existing technologies, achieve efficient, safe, and uniform sterilization effects, and meet the diverse needs of modern medicine.

[0037] Please see Figures 1-3 This application provides a new technical solution: a sterile dressing pack sterilization device, including an ethylene oxide sterilization chamber 1. The ethylene oxide sterilization chamber 1 has a sealed chamber inside for placing the dressing pack to be sterilized. The ethylene oxide sterilization chamber 1 has an air outlet 14 and an air inlet 15 on its side. The air outlet 14 and the air inlet 15 are connected to the sealed chamber inside the ethylene oxide sterilization chamber 1. The air inlet 15 is connected to a gas supply system for supplying sterilizing gas into the chamber of the ethylene oxide sterilization chamber 1. The air outlet 14 is connected to an exhaust gas treatment device for treating the exhaust gas after sterilization.

[0038] The ethylene oxide sterilization chamber 1 is equipped with a gas supply pipe 4 inside. The gas supply pipe 4 is connected to the gas supply system through the gas inlet 15. The gas supply pipe 4 is connected to a first gas pipe 411 and a second gas pipe 421 for uniformly spraying sterilizing gas into the ethylene oxide sterilization chamber 1.

[0039] A microwave generator 5 is installed on one side of the internal chamber of the ethylene oxide sterilization chamber 1. The microwave generator 5 is used to emit microwaves into the internal chamber of the ethylene oxide sterilization chamber 1. The microwaves cause the sterilizing gas molecules inside the internal chamber of the ethylene oxide sterilization chamber 1 to vibrate and rub against each other, thereby ensuring the activity of the sterilizing gas.

[0040] Specifically, the gas supply system delivers ethylene oxide sterilizing gas to the sealed chamber of the ethylene oxide sterilization chamber 1 through the air inlet 15. The gas delivery pipe 4 and its connected first gas pipe 411 and second gas pipe 421 evenly spray the gas into the chamber. The microwave generator 5 emits microwaves, causing the sterilizing gas molecules inside the chamber to vibrate and rub against each other, maintaining the gas activity to ensure the sterilization effect. This synergistic sterilization method using ethylene oxide and microwaves leverages the excellent bactericidal properties of ethylene oxide gas and the increased activity of gas molecules. The combination of these two methods can quickly and effectively kill various microorganisms, significantly shortening the sterilization time and improving sterilization efficiency.

[0041] In this embodiment, the gas supply pipe 4 is made of stainless steel, with a diameter of Φ20-30mm and a length of 1-2m.

[0042] The bottom of the internal chamber of the ethylene oxide sterilization chamber 1 is equipped with a rotating tray mechanism, on which multiple trays 6 are installed. The dressing packs are placed on the multiple trays 6. The rotating tray mechanism drives the multiple trays 6 to rotate, so that the dressing packs on the trays 6 receive sterilization gas and microwave action evenly.

[0043] Specifically, the rotating tray mechanism drives the tray 6 to rotate, ensuring that the dressing packs placed on it receive sterilization gas and microwaves evenly from all directions, completing the sterilization process. The exhaust port 14 then transports the sterilized waste gas to a waste gas treatment device for processing. By rotating the sterile dressing packs via the rotating tray, all parts of the dressing packs receive even sterilization gas and microwaves, avoiding the uneven sterilization problem present in traditional sterilization equipment and ensuring the stability and reliability of the sterilization effect. Simultaneously, the waste gas treatment device ensures safety and environmental friendliness during use.

[0044] In some embodiments, the gas supply system includes an ethylene oxide storage tank 2 for storing sterilization gas. The outlet of the ethylene oxide storage tank 2 is connected to the inlet 15 via a connecting pipe 3, for supplying sterilization gas into the chamber of the ethylene oxide sterilization chamber 1, thus providing a gas source for the sterilization process.

[0045] Specifically, a pressure regulating valve 31 and a pressure gauge 32 are installed on the connecting pipe 3. The pressure regulating valve 31 has an adjustment range of 0.1-0.8 MPa, and the pressure gauge 32 has a range of 0-1 MPa (accuracy ±1.5% FS). The pressure regulating valve 31 and the pressure gauge 32 are arranged sequentially along the gas delivery direction inside the connecting pipe 3. The pressure regulating valve 31 is used to regulate the gas pressure delivered inside the ethylene oxide storage tank 2, and the pressure gauge 32 is used to monitor the real-time gas pressure. The pressure regulating valve 31, installed on the connecting pipe 3, can adjust the pressure of the gas output from the ethylene oxide storage tank 2 according to the sterilization requirements, so that the gas pressure delivered to the sterilization chamber is stabilized within a suitable range. The pressure gauge 32 monitors the gas pressure inside the connecting pipe 3 in real time and feeds back the data, allowing operators to adjust the pressure regulating valve 31 in a timely manner to ensure that the gas delivery pressure meets the set standards. By using a pressure regulating valve and a pressure gauge, precise control of the gas delivery pressure is achieved, ensuring that the sterilizing gas enters the sterilization chamber at the appropriate pressure. This avoids damage to the equipment or affecting the sterilization effect due to excessive pressure, and also prevents incomplete sterilization due to excessively low pressure, thereby improving the stability and reliability of the sterilization process.

[0046] In some embodiments, the first air tube 411 is connected to the air supply tube 4 via a connecting tee 41. A first air hole 412 is provided on the side of the first air tube 411 adjacent to the tray 6 for spraying sterilizing gas onto the dressing pack on the tray 6. The gas can be sprayed directionally onto the dressing pack on the tray 6, allowing the dressing pack to directly contact the sterilizing gas and promote the sterilization reaction.

[0047] In this embodiment, the first air tube 411 has a diameter of Φ8-12mm, and a first air hole 412 (hole diameter Φ1-2mm) is opened every 50-100mm.

[0048] In some embodiments, the second air pipe 421 is connected to the air supply pipe 4 via a right-angle connector 42. The second air pipe 421 has a second air hole 422 for spraying sterilizing gas onto the dressing pack on the tray 6. By spraying sterilizing gas onto the dressing pack on the tray 6 through the second air hole 422, the sterilizing gas is sprayed from different angles, further enhancing the uniform distribution of the sterilizing gas in the chamber and its effect on the dressing pack.

[0049] Specifically, the second air tube 421 works in conjunction with the first air tube 411 to spray sterilizing gas onto the dressing pack from multiple directions, effectively improving the uniformity of the sterilizing gas distribution within the chamber, ensuring that all parts of the dressing pack can fully contact the sterilizing gas, avoiding sterilization dead zones, and improving the uniformity and reliability of the overall sterilization effect.

[0050] In this embodiment, the second air tube 421 is made of soft silicone (temperature resistant from -40℃ to 200℃). The second air tube 421 is positioned at the center of multiple trays 6, and a counterweight 423 is provided at the bottom of the second air tube 421 to ensure its vertical positioning within the multiple trays 6. The soft silicone material of the second air tube 421 provides good flexibility and adaptability, and the counterweight 423 at its bottom ensures its stable position within the multiple trays 6. During sterilization, the second air tube 421 can spray sterilizing gas from the center of the dressing pack, working in conjunction with other air tubes to achieve omnidirectional, no-dead-angle gas spraying.

[0051] In this embodiment, the diameter of the second air tube 421 is Φ6-10mm, and the spacing of the second air holes 422 is 30-50mm (hole diameter Φ0.5-1.5mm).

[0052] In some embodiments, the tray 6 is arranged in a circular shape, with a plurality of mounting sleeves 61 at the upper end of the tray 6 and a plurality of mounting rods 62 at the bottom of the tray 6. The mounting sleeves 61 and mounting rods 62 are arranged correspondingly, and the mounting sleeves 61 and mounting rods 62 are used to mount the plurality of trays 6 onto a rotating tray mechanism.

[0053] Specifically, the mounting rod 62 can be inserted into the mounting hole of the rotating tray mechanism, and the mounting sleeve 61 can be fitted onto the mounting rod 62 of the upper tray, thereby sequentially installing multiple trays 6 on the rotating tray mechanism to form a multi-layer placement structure. The dressing packs are placed on the trays 6 and rotate with the trays driven by the rotating tray mechanism. This tray structure design facilitates multi-layer installation, effectively utilizes the internal space of the sterilization chamber, increases the number of dressing packs that can be sterilized in a single operation, and improves the efficiency of the equipment. Simultaneously, the stable installation method ensures that the trays remain stable during rotation, guaranteeing that the dressing packs can undergo sterilization smoothly.

[0054] In this embodiment, the tray 6 is provided with a placement slot 63, which is used to place the sterilization dressing pack. The placement slot 63 is provided with grid holes 64 around its perimeter and bottom.

[0055] Specifically, the placement slot 63 on tray 6 is used to place the dressing pack. The grid holes 64 on the sides and bottom allow the sterilizing gas to penetrate the placement slot 63 and fully contact all surfaces of the dressing pack. Simultaneously, during rotation, the gas can also flow around the tray 6 through the grid holes 64, enhancing the contact effect between the gas and the dressing pack. The grid holes 64 significantly increase the contact area between the dressing pack and the sterilizing gas, ensuring that the gas can penetrate all parts of the dressing pack and preventing insufficient gas contact due to the placement slot structure. This improves the comprehensiveness and thoroughness of the sterilization effect, ensuring that the dressing pack is effectively sterilized.

[0056] In some embodiments, the rotating pallet mechanism includes a mounting plate 7, on which a turntable 72 is rotatably disposed. The turntable 72 has a plurality of mounting holes, which are adapted to the mounting rod 62 at the bottom of the pallet 6 for mounting the pallet 6.

[0057] In this embodiment, the bottom of the turntable 72 is connected to a drive motor 71 via a rotating shaft, which drives the turntable 72 to rotate on the mounting plate 7.

[0058] Specifically, the drive motor 71 drives the turntable 72 to rotate via a rotating shaft, which in turn drives the tray 6 to rotate, causing the dressing pack to rotate within the chamber for sterilization. This ensures that the turntable 72 and tray 6 can rotate stably at the set speed and direction, guaranteeing that the dressing pack receives continuous and uniform sterilization gas and microwave stimulation during the sterilization process, providing reliable power support for achieving efficient and uniform sterilization.

[0059] In some embodiments, the ethylene oxide sterilization chamber 1 is provided with a door 11 on its front side. The door 11 is installed on the front side of the ethylene oxide sterilization chamber 1 via a hinge or slide rail connection structure, and the opening and closing operation realizes the isolation or communication between the sterilization chamber and the external space. When placing or removing the dressing pack, the operator opens the door 11 and places the dressing pack on the tray 6 of the rotating tray mechanism, or removes the sterilized dressing pack from the tray 6; after the operation is completed, the door 11 is closed, and in conjunction with the chamber sealing structure, the sterilization chamber is made into a sealed space to prevent the leakage of sterilization gas. The chamber door 11 is equipped with an observation window 12 for observing the internal chamber of the ethylene oxide sterilization chamber 1. The observation window 12 is embedded in the chamber door 11 and is made of a high-temperature resistant, high-strength, and transparent material, such as tempered glass or special transparent plastic. After the chamber door is closed, the operator can directly observe the internal chamber of the sterilization chamber through the observation window 12, and monitor the status of the dressing packs during the sterilization process, as well as the gas distribution and tray rotation within the chamber, without opening the chamber door, thus avoiding damage to the chamber's airtightness and affecting the sterilization process. The ethylene oxide sterilization chamber 1 is equipped with a control panel 13, through which the equipment operating parameters can be adjusted in a timely manner to achieve precise control of the sterilization process.

[0060] In this embodiment, the observation window 12 is made of high-temperature resistant quartz glass (transmittance ≥90%).

[0061] Working principle: When using a sterile dressing pack sterilization device, the operator opens the front door 11 of the ethylene oxide sterilization chamber 1 and places the dressing pack to be sterilized into the placement slot 63 of the tray 6 of the rotating tray mechanism. The mounting rod 62 at the bottom of the dressing pack is adapted to the mounting hole on the turntable 72 of the rotating tray mechanism, and the mounting sleeve 61 at the top can be fitted into the mounting rod 62 of the upper tray to achieve multi-layer installation. After placement, the door 11 is closed.

[0062] The sterilizing gas in the ethylene oxide storage tank 2 enters the gas supply pipe 4 through the connecting pipe 3 and the air inlet 15. The gas pressure is regulated by the pressure regulating valve 31. The first gas pipe 411 is connected to the gas supply pipe 4 through the connecting tee 41. The first air hole 412 on the side of the first gas pipe 411 sprays the gas directionally onto the dressing pack on the tray 6. The second gas pipe 421 is connected to the gas supply pipe 4 through the right-angle connector 42. The second air hole 422 sprays sterilizing gas into the dressing pack on the tray 6 from different angles. At the same time, the microwave generator 5 emits microwaves into the chamber, causing the sterilizing gas molecules inside the chamber to vibrate and rub against each other, maintaining the gas activity.

[0063] The drive motor 71 drives the turntable 72 to rotate via the rotating shaft, which in turn drives the tray 6 and the dressing pack on it to rotate synchronously, so that the dressing pack receives sterilization gas and microwave action in all directions and evenly. After the set sterilization time is reached, the gas supply and microwave emission are stopped. The sterilized exhaust gas is sent to the exhaust gas treatment device through the exhaust port 14 for treatment. After treatment, the door 11 is opened and the sterilized dressing pack is taken out, completing the entire sterilization process.
