Description

Technical Field

[0001] The utility model belongs to the technical field of steam sterilization, and in particular relates to a door opening angle limiting device for a side-opening door type pulsating steam sterilizer. Background Art

[0002] The pulsating steam sterilizer is a device that uses saturated steam to sterilize medical devices and dressings that can withstand high temperatures and pressures. It is also the core equipment for high-temperature sterilization in the disinfection supply center and is currently recognized as one of the most reliable sterilization technologies. At least 70% of surgical instruments are used after pulsating steam sterilization in the disinfection supply center. Wet packs are an unavoidable problem in steam sterilization. Moisture forms a continuous liquid channel inside and outside the package, which destroys the sterility of the package, so it is considered a sterilization failure. A survey on "wet packs" was conducted in medical institutions in Australia, Belgium, Italy, and the Netherlands. The survey showed that 87% of the medical institutions participating in the survey had experienced wet packs in steam sterilizers. Once a wet pack is found, it must be repackaged and sterilized before it can be sent to the clinical department for use. Therefore, paying attention to wet packs, identifying, judging, and taking effective measures to control the occurrence of wet packs can ensure the safe and effective use of surgical instrument packs.

[0018] The utility model provides a side-opening door type pulsating steam sterilizer door opening angle limiting device as shown in the figure, comprising a steam sterilizer body 4, a sterilization rack 6 for sterilization is arranged inside the steam sterilizer body 4, a door panel 11 is hinged on one side of the sterilization rack 6, an adjustment component 7 is arranged between the door panel 11 and the steam sterilizer body 4, and a protective guide component is also arranged between the door panel 11 and the steam sterilizer body 4;

[0019] The adjustment component 7 includes an arc-shaped guide rail 704 which is arranged on the door panel 11 and can move as the door panel 11 opens. A slide groove 703 is provided on the inner side of the arc-shaped guide rail 704. A sliding block 701 is provided to slide inside the slide groove 703. A plurality of threaded holes 702 are processed on at least one side of the arc-shaped guide rail 704. The plurality of threaded holes 702 are all arranged on the path where the sliding block 701 slides inside the slide groove 703 and can be fixed in position by bolts passing through the sliding block 701 and being threadedly connected to the threaded holes 702. A limiting pin 705 is fixedly provided on the inner side of the arc-shaped guide rail 704 at the top of the steam sterilizer body 4.

[0020] Specifically, the protective guide assembly includes a guide assembly 1 embedded on one side of the steam sterilizer body 4 , a magnet 10 is fixedly provided on the door panel 11 side, and one end of the guide assembly 1 is adsorbed by the magnet 10 .

[0021] Specifically, the guide component 1 includes a rotating shaft 101 rotatably arranged inside the steam sterilizer body 4, a guide cloth 103 is wound around the rotating shaft 101, a metal strip 104 is fixedly connected to one side of the guide cloth 103, and the guide component 1 is adsorbed to the magnet 10 through the metal strip 104.

[0022] Specifically, a cavity 2 is provided inside the guide assembly 1, torsion springs 102 are connected to both ends of the rotating shaft 101, and the torsion springs 102 are fixedly connected to the inner wall of the steam sterilizer body 4, and the overall length of the metal strip 104 is less than 1 / 6 of the circumference of the door panel 11 rotating around the hinge.

[0023] Specifically, a bottom plate 8 is further provided at the bottom of the door plate 11 . The bottom plate 8 is embedded in the bottom of the steam sterilizer body 4 and can rotate and move outwards along with the rotation of the door plate 11 .

[0024] Specifically, an indicator light 5 is disposed on the top of the steam sterilizer body 4 , and a control panel is also disposed on the outside of the steam sterilizer body 4 .

[0025] Working principle: When using the utility model, after the articles on the sterilization rack 6 have completed the sterilization work inside the steam sterilizer body 4, the staff can adjust the position of the sliding block 701 on the adjustment component 7 to a suitable position, which can be adjusted to a smaller angle. Then, when the staff opens the door panel 11, the arc guide rail 704 on the adjustment component 7 can be driven to make an arc movement, and the sliding block 701 and the limiting pin 705 limit the door panel 11 so that the door panel 11 is only opened to a set smaller angle. Then, because the sterilization is high temperature, when the door is opened, the sliding block 701 is opened to a set smaller angle. When the panel 11 is opened at a small angle, the internal air pressure is relatively large, so that the internal gas will be ejected from the gap opened by the door panel 11, so that the internal high-temperature gas will contact with the external cold air on the outside of the steam sterilizer body 4, thereby avoiding the phenomenon of wet packing caused by the contact of gas inside the steam sterilizer body 4 causing the hot and cold contact to produce liquid, and then the air pressure can be estimated according to the size of the internal capacity of the steam sterilizer body 4 and the sterilization temperature, so as to control the position of the sliding block 701 on the adjustment component 7 in a targeted manner to control the opening angle of the door panel 11;

[0026] Then, by utilizing the setting of the guide assembly 1, when the door panel 11 is just opened, the adsorption force of the magnet 10 can drive the guide cloth 103 on the metal strip 104 to follow the door panel 11 at a certain angle, and the bottom plate 8 always rotates with the door panel 11, so that when the door panel 11 is opened slightly, the high-temperature air is guided by the bottom plate 8, the door panel 11 and the guide cloth 103 and discharged from the top between the door panel 11 and the steam sterilizer body 4, so that no high-temperature gas will be ejected to cause discomfort to the staff, and when the door panel 11 continues to expand the angle to open, the guide cloth 103 is limited in length and can only follow the door panel 11 at a certain angle, so that when the guide cloth 103 is extended to the maximum, it is pulled by the door panel 11 to separate the metal strip 104 from the magnet 10, thereby realizing a return to a normal open state of the door panel 11.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
