Description

Technical Field

[0001] This utility model relates to the technical field of sealing strips for oxygen chamber doors, specifically a sealing strip for an inflatable oxygen chamber door. Background Technology

[0002] The hyperbaric oxygen chamber door is a key component of the hyperbaric oxygen chamber, primarily used to isolate the internal and external environments and ensure safe entry and exit for personnel. The door provides a safe passage for both medical staff and patients during treatment. Multi-person chambers often use an inward-opening design, while single-person chambers commonly use an outward-opening design. It prevents external contaminants from entering the chamber, maintaining a clean treatment environment, which is especially crucial for patients at high risk of postoperative infection. The door's sealing strip prevents gas leakage, maintains stable pressure within the chamber, and ensures safe and effective treatment.

[0003] However, most oxygen chamber door sealing strips have poor sealing performance because they cannot completely fill the gaps. Therefore, inflatable sealing strips are used instead. However, the air filling point of the inflatable sealing strip is exposed during transportation and is prone to blockage, which makes subsequent installation and air filling inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a sealing strip for an inflatable oxygen chamber door, in order to solve the problem of easy clogging of the sealing strip for an inflatable oxygen chamber door mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing strip for an inflatable oxygen chamber door, comprising a sealing strip body and an air filling port, wherein an air filling port is provided on one side of the sealing strip body, a fixed shaft is provided at one end of the air filling port, a fixed plate is connected to the side of the fixed shaft away from the air filling port, the fixed plate is shaped as a ring, and a sealing plate is sleeved on the surface of the fixed shaft, the sealing plate being shaped as a solid circular plate.

[0006] Preferably, a sealing ring is provided on the side of the sealing strip body near the sealing plate. The sealing ring is circular in shape and made of butyl rubber.

[0007] Preferably, a slot is formed on one side of the sealing plate, and the slot is evenly distributed on the surface of the sealing plate.

[0008] Preferably, a locking block is provided on one side of the empty slot, and a limiting spring is connected between one side of the locking block and the sealing plate.

[0009] Preferably, a sealing bag is provided inside the sealing strip body. The sealing bag is evenly distributed inside the sealing strip body, and through holes are left at both ends where the sealing bag connects to the sealing strip body.

[0010] Preferably, one end of the sealed bag is provided with a membrane, and the membrane is made of expanded polytetrafluoroethylene (ePTFE) membrane.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The sealing strip for the inflatable oxygen chamber door protects the side of the air filling port with the sealing plate and fixes the position of the sealing plate with the locking block, thereby preventing external impurities from entering the interior during transportation. This gives the sealing strip for the inflatable oxygen chamber door a better anti-clogging effect during use. By setting evenly distributed sealing bags inside the sealing strip body, even if the sealing strip is damaged, multiple sealing bags can prevent direct air leakage and large gaps. Thus, the sealing strip for the inflatable oxygen chamber door has a better anti-leakage effect during use.

[0012] 1. The sealing strip for the inflatable oxygen chamber door is prone to blockage during transportation, making it inconvenient to use. This can be remedied by rotating the sealing plate along a fixed axis. This rotation causes a locking block on one side to move, which is then pressed by a locking groove inside the fixed plate. Simultaneously, the moving block presses against a limiting spring on one side, allowing it to enter the cavity. This releases the sealing plate's restraint, allowing airflow through the filling port and facilitating subsequent refilling.

[0013] 2. The sealing strip for the inflatable oxygen chamber door is prone to damage during use, resulting in large gaps and poor sealing performance. This can be addressed by incorporating evenly distributed sealing bags inside the sealing strip body, with pre-drilled grooves at both ends connecting the sealing bags to the sealing strip body. This prevents blockage during gas filling. A diaphragm made of ePTFE (expanded polytetrafluoroethylene) membrane is also provided at one end of each sealing bag. The overlapping of ePTFE membranes with different pore sizes allows for differentiation of the pore sizes within the membrane, achieving better unidirectional flow. This ensures that even if the sealing strip is damaged, multiple sealing bags prevent direct air leakage and large gaps, resulting in a better leak-proof effect for the inflatable oxygen chamber door sealing strip during use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a sealing strip for an inflatable oxygen chamber door, comprising a sealing strip body 1 and an air inlet 2. The air inlet 2 is provided on one side of the sealing strip body 1, and a fixed shaft 3 is provided at one end of the air inlet 2. A fixed plate 4 is connected to the side of the fixed shaft 3 away from the air inlet 2. The fixed plate 4 is shaped as a ring. A sealing plate 5 is sleeved on the surface of the fixed shaft 3. The sealing plate 5 is shaped as a solid circular plate. A sealing ring 6 is provided on the side of the sealing strip body 1 near the sealing plate 5. The sealing ring 6 is shaped as a ring and is made of butyl rubber. A slot 7 is opened on one side of the sealing plate 5. The slots 7 are evenly distributed on the surface of the sealing plate 5. A locking block 8 is provided on one side of the slot 7. A limiting spring 9 is connected between one side of the locking block 8 and the sealing plate 5.

[0024] In practice,

[0025] See Figures 1-6It is known that when the sealing strip of the inflatable oxygen chamber door is used, it is prone to blockage during transportation, making it inconvenient to use. By rotating the sealing plate 5 along the fixed shaft 3, the sealing plate 5 can drive the locking block 8 on one side to move. When the locking block 8 moves, it can be squeezed by the locking groove 10 inside the fixed plate 4, thus allowing the locking block 8 to move. At the same time, the locking block 8 can squeeze the limiting spring 9 on one side, allowing the locking block 8 to enter the cavity 7. As a result, the sealing plate 5 can be unrestricted after being pushed, allowing the air filling port 2 to flow, which makes subsequent air filling more convenient. After the sealing plate 5 is reset, the reset of the limiting spring 9 can drive the locking block 8 to lock with the locking groove 10, thus fixing the position of the sealing plate 5 and preventing external impurities from entering the interior during transportation. This gives the sealing strip of the inflatable oxygen chamber door a better anti-blocking effect during use.

[0026] The sealing strip body 1 has a sealing bag 11 inside. The sealing bags 11 are evenly distributed inside the sealing strip body 1, and the two ends of the sealing bag 11 connected to the sealing strip body 1 have through holes. One end of the sealing bag 11 is provided with a diaphragm 12, and the diaphragm 12 is made of expanded polytetrafluoroethylene (ePTFE) membrane.

[0027] In practice,

[0028] See Figure 1 , Figure 2 and Figure 7 It is known that when the sealing strip of the inflatable oxygen chamber door is used, it is often prone to damage, resulting in large gaps and poor sealing performance. This can be addressed by setting evenly distributed sealing bags 11 inside the sealing strip body 1, with through grooves reserved at both ends where the sealing bags 11 connect to the sealing strip body 1. This prevents blockage during gas filling at the gas filling port 2. A diaphragm 12 is also provided at one end of the sealing bag 11. The diaphragm 12 is made of ePTFE expanded polytetrafluoroethylene membrane. Because the ePTFE membrane is layered with ePTFE membranes of different pore sizes, the pore sizes inside the diaphragm 12 can be differentiated, achieving a better unidirectional flow effect. This prevents direct air leakage and large gaps caused by damage to the sealing strip, allowing it to pass through multiple sealing bags 11. Therefore, the sealing strip of the inflatable oxygen chamber door has a better anti-leakage effect during use.

[0029] In summary, the oxygen chamber door sealing strip can prevent gas leakage in the hyperbaric oxygen chamber, maintain stable pressure inside the chamber, and ensure safe and effective treatment. By rotating the sealing plate 5 along the fixed shaft 3, the sealing plate 5 can drive the locking block 8 on one side to move. The locking block 8 can then be squeezed by the locking groove 10 inside the fixed plate 4, allowing the locking block 8 to move. At the same time, the locking block 8 can squeeze the limiting spring 9 on one side, allowing the locking block 8 to enter the interior of the empty groove 7. As a result, the sealing plate 5 can be unrestricted after being pushed, allowing the gas filling port 2 to flow, which makes subsequent gas filling more convenient.
