Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an installation structure for the inner chamber of a pulsed vacuum pressure sterilizer. Background Technology

[0002] The pulsed vacuum pressure sterilizer is a key device that achieves complete sterilization of medical devices through a four-stage cycle of pre-vacuuming, steam penetration, pressure sterilization, and vacuum drying. It uses a vacuum pump to reduce the pressure inside the chamber and expel cold air, then injects saturated steam to penetrate the inside of the device lumen, and finally ensures no risk of wet packs through negative pressure drying. This equipment is widely used in hospital disinfection supply centers, biological laboratories, and pharmaceutical companies.

[0003] In the existing technology, the internal chamber installation system of the pulsed vacuum pressure sterilizer mainly consists of three parts: a fixed welded chamber, a bottom load-bearing support, and a sealing flange. The chamber is fixed to the inner wall of the sterilizer shell by continuous welds. A rotating door is installed at the opening of the chamber. The edge of the chamber opening is provided with a raised door frame step for installing the sealing ring and bearing pressure, thereby forming a closed sterilization space. The bottom of the chamber is welded with an H-shaped steel support to bear the weight of the instruments. The flange is bolted to connect the vacuum pipe and the steam inlet. The silicone sealing ring fills the interface gap to prevent leakage. The support ensures structural strength, the flange ensures airtightness, and the welded chamber maintains morphological stability under high temperature and high pressure. The rigid connection of the three supports the execution of the sterilization process.

[0004] Regarding the aforementioned technologies, the protruding door frame steps at the edge of the cabin opening and the H-shaped steel support welded to the bottom of the cabin will create dead corner areas, which may lead to water accumulation at the bottom of the cabin. The damp environment is prone to bacterial growth. Furthermore, the H-shaped steel support structure not only makes it difficult to thoroughly clean the bottom of the cabin, but may also occupy the bottom area and compress the space for placing instruments. Therefore, improvements are needed. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides an installation structure for the inner chamber of a pulsed vacuum pressure sterilizer.

[0006] The technical solution for the installation structure of the inner chamber of a pulsed vacuum pressure sterilizer provided in this application is as follows: A pulsating vacuum pressure sterilizer inner chamber installation structure includes a housing, a limiting groove formed on the inner wall of the housing, a chamber door that is raised and lowered within the limiting groove, a vacuum chamber on the inner wall of the housing, an evaporator at the lower end of the vacuum chamber, a steam pipe connected to the steam outlet of the evaporator, a check valve on the steam pipe, a vacuum drying assembly for removing residual moisture inside the vacuum chamber, and a lifting assembly for raising and lowering the chamber door on the inner wall of the housing.

[0007] By adopting the above technical solution, the chamber door is opened and the medical device is placed into the vacuum chamber. The lifting assembly in this application can lift the chamber door along the limiting groove and seal the vacuum chamber. Compared with the rotating door in the prior art, the door frame of the chamber door is flush with the inner wall of the vacuum chamber, and there are no steps or water accumulation grooves, thereby reducing the accumulation of residual moisture and bacteria and facilitating the cleaning of the vacuum chamber. When the evaporator is started, steam enters the vacuum chamber through the steam pipe and sterilizes the medical device. After sterilization, the vacuum drying assembly can vacuum dry the residual moisture in the vacuum chamber, thereby reducing the residual moisture in the vacuum chamber, keeping the vacuum chamber dry and clean, reducing the possibility of bacterial growth, and the check valve can prevent steam backflow during the vacuum sterilization stage.

[0008] Optionally, the vacuum drying assembly includes a vacuum pump, a suction pipe, a shelf, a conical water collection tank, and a hot air component. The vacuum pump is located on the inner bottom wall of the chamber. One end of the suction pipe is connected to the air inlet of the vacuum pump, and the other end is connected to the lower end of the vacuum chamber. The conical collection tank is located on the inner bottom wall of the vacuum chamber and is connected to the end of the suction pipe near the vacuum chamber. The shelf is located on the side wall of the vacuum chamber, and the hot air component is located on the inner bottom wall of the chamber. It is used to evaporate residual moisture inside the chamber and on the medical devices.

[0009] By adopting the above technical solution, the vacuum pump is started, and the vacuum pump can draw cold air from the vacuum chamber through the suction pipe. The evaporator is started, and steam is introduced into the vacuum chamber through the steam pipe until the set parameters are reached to sterilize the medical devices in the vacuum chamber. After that, the vacuum pump is started again, and the vacuum pump can draw steam from the vacuum chamber through the suction pipe. Moisture on the medical devices can flow through the shelf into the conical water collection tank, and moisture on the side wall of the vacuum chamber can also flow into the conical water collection tank. Finally, it is discharged through the suction pipe. After discharge, suction is performed again to reduce the pressure and boiling point of the liquid in the vacuum chamber, thereby achieving vacuum evaporation of moisture in the vacuum chamber, reducing the residual moisture in the vacuum chamber, keeping the vacuum chamber dry and clean, and reducing the possibility of bacterial growth.

[0010] Optionally, the hot air component includes a hot air blower and a hot air pipe. The hot air blower is disposed on the inner bottom wall of the housing. One end of the hot air pipe is connected to the air outlet of the hot air blower, and the other end is connected to the end of the steam pipe near the vacuum chamber.

[0011] By adopting the above technical solution, after the steam in the vacuum chamber is extracted, the hot air fan is started and the check valve is closed. Hot air is introduced into the vacuum chamber through the hot air pipe and the steam pipe. The hot air can further evaporate the moisture remaining in the vacuum chamber and on the medical devices, and can also repeatedly replace the moisture in the vacuum chamber, thereby further reducing the moisture remaining in the vacuum chamber and evaporating the medical devices, shortening the drying time and improving the sterilization efficiency.

[0012] Optionally, the lifting assembly includes a drive motor, sprockets, a rotating rod, a chain, and a connecting block. The drive motor is mounted on the side wall of the housing. The rotating rod is mounted on the output end of the drive motor and rotatably mounted on the side wall of the housing. Two sets of sprockets are provided, one on the rotating rod and the other on the side wall of the housing. The chain is sleeved on the two sets of sprockets and meshes with them. One end of the connecting block is fixedly connected to the cabin door, and the other end is fixedly connected to the chain.

[0013] By adopting the above technical solution, the drive motor is started, and the output end of the drive motor rotates to drive the rotating rod to rotate. The rotation of the rotating rod drives the sprocket on the rotating rod to rotate. The rotation of the sprocket on the rotating rod drives the chain and the sprocket below to rotate. The rotation of the chain drives the connecting block to rise and fall. The rise and fall of the connecting block drives the cabin door to rise and fall, thereby realizing the raising and lowering of the cabin door along the limiting groove. Compared with the existing technology of revolving door, which requires a raised door frame step at the edge of the cabin opening, the door frame of the cabin door is designed to be flush with the inner wall of the vacuum chamber, with no vertical drop, and no steps or water accumulation tanks, thereby reducing the accumulation of residual moisture and bacteria, and facilitating the cleaning of the vacuum chamber.

[0014] Optionally, a steam diffusion hood is provided at the end of the steam pipe near the vacuum chamber, and a grid plate is provided inside the steam diffusion hood.

[0015] By adopting the above technical solutions, the steam diffusion hood can prevent steam from being directly sprayed onto medical devices, avoiding local overheating of the medical devices. In addition, it can increase the coverage area of ​​steam and hot air, improve the temperature uniformity inside the vacuum chamber, and thus enhance the sterilization and moisture evaporation effects. The grid plate can divert the steam output from the steam pipe, thereby guiding the steam to the edge area of ​​the vacuum chamber.

[0016] Optionally, the sidewall of the vacuum chamber is a corrugated chamber wall, and the protrusions are fixedly connected to the shelf.

[0017] By adopting the above technical solution, a directional flow channel can be formed in the concave part of the corrugated chamber wall for the steam and moisture extraction stage. The directional flow channel can cause the liquid to collect in the conical water collection tank along the flow channel, thereby reducing the liquid residue on the side wall of the vacuum chamber. In addition, the air circulation channel formed in the concave part between the corrugations during the hot air drying stage can accelerate the evaporation of moisture on the side wall of the vacuum chamber, improve the evaporation effect, and thus inhibit bacterial growth.

[0018] Optionally, multiple sets of ventilation holes are provided on the side wall of the enclosure.

[0019] By adopting the above technical solution, the ventilation holes can improve the heat dissipation capacity of the enclosure, prevent the internal temperature of the enclosure from becoming too high, and thus improve the stability of equipment operation.

[0020] Optionally, casters are provided at the lower end of the housing.

[0021] By adopting the above technical solution, casters make it easier for medical staff to adjust the position of the sterilizer, saving transportation time and reducing adjustment difficulty.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The vacuum drying assembly in this application can vacuum dry the residual moisture in the chamber. The vacuum pump is started, drawing in cold air from the vacuum chamber through the suction pipe. The evaporator is started, introducing steam into the vacuum chamber through the steam pipe until the set parameters are reached, sterilizing the medical devices inside the vacuum chamber. The vacuum pump is then started again, drawing in steam from the vacuum chamber through the suction pipe. Moisture on the medical devices flows through the shelf into the conical water collection tank, and moisture on the side wall of the vacuum chamber also flows into the conical water collection tank, finally being discharged through the suction pipe. After discharge, suction is performed again, lowering the pressure and boiling point of the liquid inside the vacuum chamber, thereby achieving vacuum drying of the moisture inside the vacuum chamber, reducing residual moisture, keeping the vacuum chamber dry and clean, and reducing the possibility of bacterial growth. 2. The hot air component in this application can evaporate the residual moisture inside the chamber and on the medical device. After the steam inside the vacuum chamber is extracted, the hot air fan is started and the check valve is closed. Hot air is introduced into the vacuum chamber through the hot air pipe and the steam pipe. The hot air can further evaporate the residual moisture inside the vacuum chamber and on the medical device, and can also repeatedly replace the moisture inside the vacuum chamber, thereby further reducing the residual moisture inside the vacuum chamber and evaporating the medical device, shortening the drying time and improving the sterilization efficiency. 3. The lifting assembly in this application can raise and lower the cabin door. When the drive motor is started, the output end of the drive motor drives the rotating rod to rotate. The rotation of the rotating rod drives the sprocket on the rotating rod to rotate. The rotation of the sprocket on the rotating rod drives the chain and the sprocket below to rotate. The rotation of the chain drives the connecting block to rise and fall. The rise and fall of the connecting block drives the cabin door to rise and fall, thereby realizing the raising and lowering of the cabin door along the limiting groove. Compared with the rotating door in the prior art, which requires a raised door frame step at the edge of the cabin opening, the door frame of the cabin door is flush with the inner wall of the vacuum chamber, with no vertical drop, and no steps or water accumulation tank, thereby reducing the accumulation of residual moisture and bacteria, and facilitating the cleaning of the vacuum chamber. 4. The corrugated chamber wall recesses in this application can form directional flow channels for the steam and moisture extraction stages. The directional flow channels can cause liquid to collect along the channels into the conical water collection tank, thereby reducing the liquid residue on the side wall of the vacuum chamber. In addition, during the hot air drying stage, the air circulation channels formed in the corrugations can accelerate the evaporation of moisture on the side wall of the vacuum chamber, improve the evaporation effect, and thus inhibit bacterial growth.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses an installation structure for the inner chamber of a pulsed vacuum pressure sterilizer, referring to... Figure 1 and Figure 2 The inner chamber installation structure of the pulsed vacuum pressure sterilizer includes a box body 1. A limiting groove 11 is opened on the inner wall of the box body 1. A chamber door 12 is installed in the limiting groove 11. A vacuum chamber 13 is bolted to the inner wall of the box body 1. An evaporator 14 is fixedly installed at the lower end of the vacuum chamber 13. A steam pipe 15 is connected to the steam outlet end of the evaporator 14. The end of the steam pipe 15 away from the evaporator 14 is connected to the upper end of the vacuum chamber 13. A check valve 16 is fixedly installed on the steam pipe 15. A vacuum drying assembly 2 is installed inside the vacuum chamber 13. A lifting assembly 4 is installed on the inner wall of the box body 1.

[0028] Open the chamber door 12 and place the medical device into the vacuum chamber 13. In this embodiment, the lifting assembly 4 can raise and lower the chamber door 12 along the limiting groove 11 and seal the vacuum chamber 13. Compared with the rotating door in the prior art, the door frame of the chamber door 12 is flush with the inner wall of the vacuum chamber 13, and there are no steps or water accumulation grooves, thereby reducing the accumulation of residual moisture and bacteria, and facilitating the cleaning of the vacuum chamber 13. Start the evaporator 14, and steam enters the vacuum chamber 13 through the steam pipe 15 to sterilize the medical device. After sterilization, the vacuum drying assembly 2 can vacuum dry the residual moisture in the vacuum chamber 13, thereby reducing the residual moisture in the vacuum chamber 13, keeping the vacuum chamber 13 dry and clean, and reducing the possibility of bacterial growth. The check valve 16 can prevent the steam from flowing back during the vacuum sterilization stage. In this embodiment, the limiting groove 11 and the chamber door 12 are symmetrically arranged in two sets, with chamber doors 12 opened at both ends to facilitate medical personnel to perform sterilization operations and take out and put in medical devices.

[0029] Reference Figure 1 and Figure 2 After sterilization of medical devices, moisture may remain inside the vacuum chamber 13, which can breed bacteria. Therefore, the vacuum drying component 2 in this embodiment includes a vacuum pump 21, a suction pipe 22, a shelf 23, a conical water collection tank 24, and a hot air component 3. The vacuum pump 21 is bolted to the inner bottom wall of the housing 1. One end of the suction pipe 22 is connected to the air inlet of the vacuum pump 21, and the other end is connected to the lower end of the vacuum chamber 13. The conical collection tank is welded to the inner bottom wall of the vacuum chamber 13 and is connected to the end of the suction pipe 22 near the vacuum chamber 13. The shelf 23 is welded to the side wall of the vacuum chamber 13, and the hot air component 3 is installed on the inner bottom wall of the housing 1.

[0030] The vacuum pump 21 is started, and the vacuum pump 21 can draw cold air from the vacuum chamber 13 through the suction pipe 22. The evaporator 14 is started, and steam is introduced into the vacuum chamber 13 through the steam pipe 15 until the set parameters are reached. After sterilizing the medical devices in the vacuum chamber 13, the vacuum pump 21 is started again, and the vacuum pump 21 can draw steam from the vacuum chamber 13 through the suction pipe 22. The moisture on the medical devices can flow into the conical water collection tank 24 through the shelf 23. The moisture on the side wall of the vacuum chamber 13 can also flow into the conical water collection tank 24 and finally be discharged through the suction pipe 22. After discharge, suction is performed again to reduce the pressure and boiling point of the liquid in the vacuum chamber 13, thereby achieving vacuum evaporation of the moisture in the vacuum chamber 13, reducing the residual moisture in the vacuum chamber 13, keeping the vacuum chamber 13 dry and clean, and reducing the possibility of bacterial growth.

[0031] Reference Figure 2 In order to further evaporate the residual moisture in the vacuum chamber 13, the hot air component 3 in this embodiment includes a hot air blower 31 and a hot air pipe 32. The hot air blower 31 is bolted to the inner bottom wall of the housing 1. One end of the hot air pipe 32 is connected to the air outlet of the hot air blower 31, and the other end is connected to the end of the steam pipe 15 near the vacuum chamber 13.

[0032] After the steam in the vacuum chamber 13 is extracted, the hot air blower 31 is started and the check valve 16 is closed. Hot air is introduced into the vacuum chamber 13 through the hot air pipe 32 and the steam pipe 15. The hot air can further evaporate the residual moisture in the vacuum chamber 13 and on the medical devices, and can also repeatedly replace the moisture in the vacuum chamber 13, thereby further reducing the residual moisture in the vacuum chamber 13 and evaporating the medical devices, shortening the drying time and improving the sterilization efficiency.

[0033] Reference Figure 1 and Figure 2 Before and after sterilization, the chamber door 12 needs to be raised and lowered. Therefore, the lifting assembly 4 in this embodiment includes a drive motor 41, a sprocket 42, a rotating rod 43, a chain 44, and a connecting block 45. The drive motor 41 is bolted to the side wall of the chamber 1. The rotating rod 43 is welded to the output end of the drive motor 41 and is rotatably mounted on the side wall of the chamber 1. Two sets of sprockets 42 are provided. The two sets of sprockets 42 are respectively mounted on the rotating rod 43 and the side wall of the chamber 1. The chain 44 is sleeved on the two sets of sprockets 42 and meshes with the two sets of sprockets 42. One end of the connecting block 45 is fixedly connected to the chamber door 12, and the other end is fixedly connected to the chain 44.

[0034] The drive motor 41 is started, and the output end of the drive motor 41 drives the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the sprocket 42 on the rotating rod 43 to rotate. The rotation of the sprocket 42 on the rotating rod 43 drives the chain 44 and the lower sprocket 42 to rotate. The rotation of the chain 44 drives the connecting block 45 to rise and fall. The rise and fall of the connecting block 45 drives the cabin door 12 to rise and fall, thereby realizing the raising and lowering of the cabin door 12 along the limiting groove 11. Compared with the existing technology of revolving doors that require a raised door frame step at the edge of the cabin opening, the door frame of the cabin door 12 is flush with the inner wall of the vacuum chamber 13, with no vertical drop, no steps, and no water accumulation tank, thereby reducing the accumulation of residual moisture and bacteria, and facilitating the cleaning of the vacuum chamber 13.

[0035] In this embodiment, four sets of sprockets 42 are symmetrically arranged, and two sets of connecting blocks 45 and chains 44 are symmetrically arranged. The four sets of sprockets 42, two sets of chains 44 and two sets of connecting blocks 45 can improve the stability of the lifting of the cabin door 12. In addition, two sets of lifting components 4 are symmetrically arranged in this embodiment, and the other set can lift the cabin door 12 at the other end of the vacuum chamber 13.

[0036] Reference Figure 1 and Figure 3 Directly outputting steam through the steam pipe 15 may damage medical devices. Therefore, in this embodiment, a steam diffusion hood 5 is fixedly installed at the end of the steam pipe 15 near the vacuum chamber 13. A grid plate is welded inside the steam diffusion hood 5. The steam diffusion hood 5 can prevent steam from directly spraying onto the medical devices and avoid local overheating of the medical devices. In addition, it can increase the coverage area of ​​steam and hot air, improve the temperature uniformity inside the vacuum chamber 13, and thus improve the sterilization effect and moisture evaporation effect. The grid plate can divert the steam output from the steam pipe 15, thereby guiding the steam to the edge area of ​​the vacuum chamber 13.

[0037] Reference Figure 1 and Figure 3 To reduce residual moisture on the sidewalls of the vacuum chamber 13, the sidewalls of the vacuum chamber 13 in this embodiment are corrugated chamber walls 6, with the protrusions fixedly connected to the shelf 23. The concave areas of the corrugated chamber wall 6 can form directional flow channels for the steam and moisture extraction stages. The directional flow channels can cause liquid to collect along the channels into the conical water collection tank 24, thereby reducing the residual liquid on the sidewalls of the vacuum chamber 13. In addition, during the hot air drying stage, the air circulation channels formed in the concave areas between the corrugations can accelerate the evaporation of moisture on the sidewalls of the vacuum chamber 13, improve the evaporation effect, and thus inhibit bacterial growth.

[0038] Reference Figure 1The evaporator 14, vacuum pump 21 and hot air blower 31 at the bottom of the housing 1 need to dissipate heat during operation. Therefore, in this embodiment, multiple sets of ventilation holes 7 are opened on the side wall of the housing 1. The ventilation holes 7 can improve the heat dissipation capacity of the housing 1, avoid the internal temperature of the housing 1 from being too high, and thus improve the stability of equipment operation.

[0039] Reference Figure 2 In case of emergencies, the position of the sterilizer needs to be adjusted. To facilitate the adjustment of the sterilizer's position, casters 8 are rotatably installed at the lower end of the housing 1 in this embodiment. The casters 8 make it easier for medical staff to adjust the position of the sterilizer, saving transportation time and reducing adjustment difficulty. The casters 8 in this embodiment have a locking function. After the position is adjusted, the casters 8 can be locked to keep the sterilizer stable during use.

[0040] The implementation principle of the inner chamber installation structure of a pulsed vacuum pressure sterilizer according to an embodiment of this application is as follows: Start the vacuum pump 21. The vacuum pump 21 can draw cold air from the vacuum chamber 13 through the suction pipe 22. Start the evaporator 14. Steam is introduced into the vacuum chamber 13 through the steam pipe 15 until the set parameters are reached. After sterilizing the medical devices in the vacuum chamber 13, start the vacuum pump 21 again. The vacuum pump 21 can draw steam from the vacuum chamber 13 through the suction pipe 22. Moisture on the medical devices can flow into the conical water collection tank 24 through the shelf 23. Moisture on the side wall of the vacuum chamber 13 can also flow into the conical water collection tank 24. Finally, it is discharged through the suction pipe 22. After discharge, suction is performed again to reduce the pressure and boiling point of the liquid in the vacuum chamber 13. This achieves vacuum evaporation of the moisture in the vacuum chamber 13, reduces the residual moisture in the vacuum chamber 13, keeps the vacuum chamber 13 dry and clean, and reduces the possibility of bacterial growth. After the steam in the vacuum chamber 13 is extracted, the hot air blower 31 is started and the check valve 16 is closed. Hot air is introduced into the vacuum chamber 13 through the hot air pipe 32 and the steam pipe 15. The hot air can further evaporate the moisture remaining in the vacuum chamber 13 and on the medical device, and repeatedly replace the moisture in the vacuum chamber 13, thereby further reducing the moisture remaining in the vacuum chamber 13 and evaporating the medical device, shortening the drying time and improving the sterilization efficiency. Start the drive motor 41. The output end of the drive motor 41 drives the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the sprocket 42 on the rotating rod 43 to rotate. The rotation of the sprocket 42 on the rotating rod 43 drives the chain 44 and the lower sprocket 42 to rotate. The rotation of the chain 44 drives the connecting block 45 to rise and fall. The rise and fall of the connecting block 45 drives the cabin door 12 to rise and fall, thereby realizing the rise and fall of the cabin door 12 along the limiting groove 11. Compared with the existing technology of the rotating door, which requires a raised door frame step at the edge of the cabin opening, the door frame of the cabin door 12 is flush with the inner wall of the vacuum chamber 13, with no vertical drop, no steps, and no water accumulation tank, thereby reducing the accumulation of residual moisture and bacteria, and making it easier to clean the vacuum chamber 13. In this embodiment, the concave part of the corrugated chamber wall 6 can form a directional flow channel for the steam and moisture extraction stage. The directional flow channel can cause the liquid to collect in the conical water collection tank 24 along the flow channel, thereby reducing the liquid residue on the side wall of the vacuum chamber 13. In addition, the air circulation channel formed in the concave part between the corrugations during the hot air drying stage can accelerate the evaporation of moisture on the side wall of the vacuum chamber 13, improve the evaporation effect of moisture, and thus inhibit bacterial growth.
