Description

Technical Field

[0001] This utility model belongs to the field of oxygen chamber technology, specifically relating to an oxygen chamber pneumatic control device. Background Technology

[0002] Medical oxygen chambers play a vital role in modern medicine. In treating diseases, they can significantly improve various hypoxic conditions. For example, for patients with carbon monoxide poisoning, a medical oxygen chamber can provide a high-concentration oxygen environment. Carbon monoxide has a much stronger affinity for hemoglobin than oxygen, hindering normal oxygen transport. However, in an oxygen chamber, the high concentration of oxygen promotes the dissociation of carbon monoxide from hemoglobin and accelerates its expulsion, increasing blood oxygen levels and improving tissue hypoxia. Another example is anaerobic bacterial infections. These bacteria thrive in anaerobic or low-oxygen environments; the high-oxygen environment created by a medical oxygen chamber effectively inhibits their growth, assisting antibiotic treatment and improving cure rates. Furthermore, for diseases caused by local tissue hypoxia due to vascular lesions, such as diabetic foot and ischemic cerebral diseases, hyperbaric oxygen therapy can increase tissue oxygen supply, promote the repair and regeneration of damaged tissues, alleviate symptoms, and improve prognosis.

[0003] In the field of oxygen chamber technology, the sealing and locking of oxygen chamber doors is a crucial aspect of ensuring the safe and effective operation of oxygen chambers. For oxygen chambers, effective door sealing and locking have numerous important implications.

[0004] Traditional oxygen chamber door sealing and locking structures are often complex and cumbersome to operate, requiring multiple steps to complete the sealing and locking actions. This not only consumes a lot of time and manpower but is also prone to poor sealing or insecure locking due to improper operation. For example, some early oxygen chamber door designs may have required manual adjustment of the sealing components before locking using mechanical latches or other methods. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic control device for an oxygen chamber, which can simultaneously lock and seal the sealed chamber door through the action of the secondary sealing ring, thereby enabling one-button control of the locking and sealing of the sealed chamber door.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An oxygen chamber pneumatic control device includes an oxygen chamber body, with a hatch on the front side of the oxygen chamber body. A ring-shaped hatch connecting plate is fixedly connected to the front side of the oxygen chamber body and outside the hatch. A main ring groove with a front opening is formed inside the ring-shaped hatch connecting plate. A secondary ring groove is also formed inside the ring-shaped hatch connecting plate. The secondary ring groove is located on one side of the main ring groove, and the side of the secondary ring groove closest to the main ring groove is connected to the main ring groove.

[0008] A rotating plate is rotatably connected to the front of the oxygen chamber body. A sealed door is fixedly connected to the rotating plate. A main sealing ring is fixedly connected to the inner side of the annular door connecting plate. The main sealing ring is installed inside the main annular groove. An annular mounting groove is opened on the side of the main sealing ring. A secondary sealing ring is installed inside the annular mounting groove. The secondary sealing ring can be inflated and extended into the interior of the secondary annular groove.

[0009] Furthermore, an annular air guide cavity is formed inside the secondary sealing ring, and an air pump is fixedly connected to the outside of the sealed door. The air pump is connected to the annular air guide cavity inside the secondary sealing ring.

[0010] The technical effects achieved by this utility model are as follows:

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figures 1-3As shown, an oxygen chamber pneumatic control device includes an oxygen chamber body 1. A hatch 2 is provided on the front side of the oxygen chamber body 1, through which a user can enter the interior of the oxygen chamber body 1. A ring-shaped hatch connecting plate 3 is fixedly connected to the front side of the oxygen chamber body 1 and outside the hatch 2. A main ring groove 7 with a front opening is provided inside the ring door connecting plate 3. A secondary ring groove 9 is also provided inside the ring door connecting plate 3. The secondary ring groove 9 is located on one side of the main ring groove 7, that is, the secondary ring groove 9 is located inside or outside the main ring groove 7, and the side of the secondary ring groove 9 closest to the main ring groove 7 is connected to the main ring groove 7, so that the main ring groove 7 and the secondary ring groove 9 form a concave-convex locking groove.

[0019] A rotating plate 5 is rotatably connected to the front of the oxygen chamber 1. A sealing door 4 is fixedly connected to the rotating plate 5. The sealing door 4 is rotatably connected to the front of the annular door connecting plate 3 and abuts against the annular door connecting plate 3, thereby sealing the hatch 2. A main sealing ring 8 is fixedly connected to the inner side of the annular door connecting plate 3. When the sealing door 4 rotates to the front of the annular door connecting plate 3, the main sealing ring 8 is installed inside the main annular groove 7. An annular mounting groove 14 is opened on the side of the main sealing ring 8. The annular mounting groove 14 is opened on the inner or outer side of the main sealing ring 8. A secondary sealing ring is installed inside the annular mounting groove 14. 10. The secondary sealing ring 10 can extend into the interior of the secondary annular groove 9, thereby forming a concave-convex locking member with the main sealing ring 8 and the secondary sealing ring 10. This allows the locking member composed of the main sealing ring 8 and the secondary sealing ring 10 to be locked inside the locking groove composed of the main annular groove 7 and the secondary annular groove 9, thus locking the sealed hatch 4. The locking member in the locked state abuts against the inner wall of the main sealing ring 8, the secondary sealing ring 10 and the annular hatch connecting plate 3, resulting in good airtightness between the annular hatch connecting plate 3 and the sealed hatch 4. This allows for one-button synchronous start and completion of locking and sealing of the sealed hatch 4, making the operation relatively simple and the sealing performance good.

[0020] At the same time, such as Figures 2-3 As shown, a corrugated shaping part 12 is provided on the side of the secondary annular groove 9 away from the main annular groove 7. When the secondary sealing ring 10 and the corrugated shaping part 12 abut against each other, the corrugated shaping part 12 can squeeze and shape the side wall of the secondary sealing ring 10, so that the side wall of the secondary sealing ring 10 and the corrugated shaping part 12 in contact forms a corrugated sealing part 13. Thus, the sealing performance between the secondary sealing ring 10 and the annular hatch connecting plate 3 can be improved through the cooperation of the corrugated shaping part 12 and the corrugated sealing part 13.

[0021] Here, the corrugated shaping part 12 refers to a section with a corrugated shape.

[0022] The secondary sealing ring 10 can be pushed into the secondary annular groove 9 by a pushing mechanism, or it can automatically extend into the secondary annular groove 9 by its expansion and deformation. This technical solution chooses to use the expansion and deformation of the secondary sealing ring 10 to automatically extend into the secondary annular groove 9, as detailed below. Figures 1-3 As shown, an annular air guide cavity 11 is formed inside the secondary sealing ring 10. An air pump 15 is fixedly connected to the outside of the sealed door 4. The air pump 15 is connected to the annular air guide cavity 11 inside the secondary sealing ring 10, thereby adjusting the air pressure inside the annular air guide cavity 11 through the air pump 15 to control the expansion or contraction of the secondary sealing ring 10. When the secondary sealing ring 10 is in a contracted state, it can be contracted into the annular mounting groove 14. When the secondary sealing ring 10 is expanded, it can be expanded and extended into the secondary annular groove 9.

[0023] Specifically, the air pump 15 can be directly connected to the annular air guide chamber 11, or it can be like... Figure 3 As shown, the air pump 15 is connected to an air guide pipe 16 extending into the annular air guide cavity 11. The air guide pipe 16 has multiple air holes, which are evenly distributed inside the annular air guide cavity 11, so that the air pressure inside the annular air guide cavity 11 can be adjusted relatively evenly through the multiple air holes.

[0024] At the same time, such as Figures 1-3 As shown, a heater 17 can also be fixedly connected to the outside of the sealed door 4. The heater 17 is electrically connected to a heating wire 18 located inside the annular air guide cavity 11. The heating wire 18 can maintain a relatively stable temperature inside the annular air guide cavity 11.

[0025] like Figures 1-2 As shown, a cylinder 6 can be fixedly connected to the rotating plate 5. The output end of the cylinder 6 is fixedly connected to the sealing door 4. When the rotating plate 5 is rotated, the sealing door 4 is located in front of the annular door connecting plate 3. Then, the cylinder 6 can be started to push the sealing door 4 towards the annular door connecting plate 3 from the front side, so that the main sealing ring 8 can move linearly when it enters the main annular groove 7. This allows a small gap to be maintained between the main sealing ring 8 and the main annular groove 7, without the need to reserve a large gap to accommodate the rotation of the main sealing ring 8.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
