Description

[0002] Hyperbaric oxygen chamber is a special medical device for high-pressure oxygen therapy, usually composed of a chamber, an exhaust (oxygen) supply system, an air conditioning system, and a control system. When the hyperbaric oxygen chamber is in use, pure oxygen or purified compressed air is input into the chamber through pipes and a control system.

[0003] The entrance and exit of the hyperbaric oxygen chamber are equipped with a door. The door of the existing hyperbaric oxygen chamber is generally controlled by a simple door lock to control the opening and closing state of the door. Due to the pressure difference between the inside and outside of the door, the door lock cannot fully control the door. The stability of the door is poor. When the pressure in the oxygen chamber is too high, the door is easily impacted and bounced off the surface of the oxygen chamber. In addition, the existing door only controls the oxygen chamber by sealing strips at the door gap.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1 , Figure 2 , Figure 4As shown, it is a structural diagram of a hyperbaric oxygen chamber door provided by an embodiment of the present invention, comprising a bulkhead 1, a door hole 11 is opened on the surface of the bulkhead 1, a door panel 2 is rotatably mounted on the surface of the bulkhead 1, a door core 21 which cooperates with the door hole 11 is fixedly mounted on the inner side wall of the door panel 2, an annular sealing strip 3 is fixedly mounted on the inner side wall of the door panel 2, a pressure loss monitoring component 4 which cooperates with the sealing strip 3 is arranged on the surface of the door panel 2, and the pressure loss monitoring component 4 is mutually engaged with the sealing strip 3. The leakage condition in the hyperbaric oxygen chamber is detected in a coordinated manner. The door core 21 is provided with an opening and closing mechanism 5 that cooperates with the bulkhead 1. The opening and closing mechanism 5 includes a clamping component 51 and an adjusting component 52. The clamping component 51 is located in the door core 21 and is connected to the door opening 11. The clamping component 51 is used to fix the position of the door core 21 and the door panel 2 in the door opening 11. The adjusting component 52 includes an inner control part 521 and an outer control part 522. The inner control part 521 Located in the door core 21 and connected to the clamping assembly 51, the internal control part 521 is used to adjust the opening and closing state of the door panel 2 in the hyperbaric oxygen chamber by cooperating with the clamping assembly 51. The external control part 522 is located on the surface of the door panel 2. The external control part 522 is used to adjust the opening and closing state of the door panel 2 outside the hyperbaric oxygen chamber by cooperating with the clamping assembly 51. The surface of the bulkhead 1 is provided with a protective mechanism 7 that cooperates with the door panel 2. The protective mechanism 7 includes a protective rod 71, a storage assembly 72 and a positioning assembly 73, the protective rod 71 is provided with multiple groups, the storage assembly 72 is located on the surface of the bulkhead 1 and is connected to the protective rod 71, the storage assembly 72 is used to store and store multiple groups of protective rods 71 ​​above the door opening 11, the positioning assembly 73 is connected to the storage assembly 72, when the pressure difference on both sides of the bulkhead 1 reaches the limit value, the positioning assembly 73 controls the multiple groups of protective rods 71 ​​to be sequentially sleeved on the outside of the door panel 2 by cooperating with the storage assembly 72.

[0032] Initially, the snap-fit ​​assembly 51 fixes the positions of the door core 21 and the door panel 2 in the door opening 11. At this time, the door opening 11 is in a closed state. When the user needs to enter the hyperbaric oxygen chamber, the external control unit 522 cooperates with the snap-fit ​​assembly 51 to release the restriction on the door core 21 in the door opening 11, and then the door panel 2 can be conveniently rotated to switch the door opening 11 to an open state. After the user enters the hyperbaric oxygen chamber, the door panel 2 is rotated to move the door core 21 into the door opening 11 again. The internal control unit 521 cooperates with the snap-fit ​​assembly 51 to conveniently fix the door core 21 in the door opening 11. At this time, the door opening 11 is converted into a closed state again, and the sealing strip 3 can automatically seal the gap between the bulkhead 1 and the door panel 2. At this time, the inner cavity of the hyperbaric oxygen chamber is in a high-pressure state. During use, the decompression monitoring assembly 4 can monitor the pressure in the hyperbaric oxygen chamber in real time. When the air in the hyperbaric oxygen chamber flows out from the gaps around the door panel 2, the decompression monitoring assembly 4 can promptly send out an alarm signal. When the hyperbaric oxygen chamber is in use, the clamping assembly 51 in the door opening 11 can provide all-round clamping protection for the door core 21, effectively improving the stability of the door core 21 and the door panel 2. Through the cooperation between the internal control unit 521 and the external control unit 522, the door panel 2 can be opened and closed from both the inside and the outside of the hyperbaric oxygen chamber, effectively improving the use effect.

[0033] When the hyperbaric oxygen chamber is in normal use, the storage assembly 72 positions the multiple sets of protection rods 71. At this time, the multiple sets of protection rods 71 ​​are always above the door opening 11. When the air pressure in the hyperbaric oxygen chamber abnormally rises to a limit value, the positioning assembly 73 cooperates with the storage assembly 72 to automatically adjust the positions of the multiple sets of protection rods 71. The multiple sets of protection rods 71 ​​move vertically downward along the surface of the bulkhead 1 in sequence and are sleeved on the outside of the door panel 2. The multiple sets of protection rods 71 ​​can further protect the door panel 2 from impact to prevent the pressure difference on both sides of the bulkhead 1 from bouncing the door panel 2 and causing harm to nearby personnel.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the pressure loss monitoring component 4 includes a detection strip 41 fixedly installed on the inner wall of the door panel 2 and located on the outside of the sealing strip 3, a cavity 42 is formed between the sealing strip 3 and the detection strip 41, an air guide hole 43 connected to the cavity 42 is opened on the surface of the door panel 2, and a monitoring airbag 44 is fixedly installed on the surface of the door panel 2, and the monitoring airbag 44 is connected to the air guide hole 43.

[0035] When the hyperbaric oxygen chamber is in use, the sealing strip 3 can automatically seal the gap between the bulkhead 1 and the door panel 2, thereby maintaining the high-pressure environment in the hyperbaric oxygen chamber. When the sealing strip 3 is used for too long and leaks, the air in the hyperbaric oxygen chamber leaks into the cavity 42 and further flows through the air guide hole 43 to the monitoring airbag 44. At this time, the monitoring airbag 44 is filled with air and expands. After the staff outside the hyperbaric oxygen chamber sees the expansion of the monitoring airbag 44, they can promptly learn about the leakage of the hyperbaric oxygen chamber and promptly replace the sealing strip 3, thereby effectively improving the use effect of the hyperbaric oxygen chamber. It is effectively prevented that the staff cannot promptly detect the leakage of the hyperbaric oxygen chamber.

[0036] like Figure 4 , Figure 5 , Figure 7 As shown, as a preferred embodiment of the present invention, the snap-in assembly 51 includes a plurality of snap-in holes 511 arranged in parallel in the vertical direction and respectively opened on the two side walls opposite to each other of the door opening 11, two groups of relatively distributed telescopic cavities 512 are opened inside the door core 21, and a plurality of connecting holes 515 connected to the telescopic cavities 512 are opened inwardly on the side walls of the door core 21, a vertical plate 514 is slidably installed in the telescopic cavity 512, and a plurality of snap-in columns 516 passing through the connecting holes 515 and cooperating with the snap-in holes 511 are fixedly installed on the side walls of the vertical plate 514, and an extrusion spring 513 connected to the vertical plate 514 is fixedly installed in the telescopic cavity 512.

[0037] When it is necessary to rotate the door panel 2 to close the door opening 11, initially, the vertical plate 514 can be pulled to move in the telescopic cavity 512 through the internal control part 521 or the external control part 522, and the vertical plate 514 drives the clamping column 516 to move synchronously. After the clamping column 516 moves as a whole into the door core 21, the door core 21 can be conveniently moved into the door opening 11. After the door core 21 moves to the door opening 11, the restriction on the vertical plate 514 is released through the internal control part 521 or the external control part 522. At this time, the extrusion spring 513 pushes the vertical plate 514 to move in the opposite direction in the telescopic cavity 512, and the vertical plate 514 drives the clamping column 516 to move synchronously. At this time, the clamping column 516 is inserted into the clamping hole 511 on the side wall of the door opening 11, and multiple groups of clamping columns 516 cooperate with the clamping holes 511. The position of the door core 21 can be conveniently fixed in the door opening 11, and the door opening 11 is in a closed state.

[0038] When the door panel 2 needs to be opened from the inside or outside of the hyperbaric oxygen chamber, the vertical plate 514 can be pulled to move in the telescopic cavity 512 through the internal control unit 521 or the external control unit 522, and the vertical plate 514 drives the clamping column 516 to move synchronously. After the clamping column 516 moves as a whole into the door core 21, the clamping column 516 and the clamping hole 511 are separated from each other. At this time, the door panel 2 and the door core 21 can be easily rotated, and the door opening 11 can be converted to an open state.

[0039] like Figure 2 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the internal control part 521 includes an equipment cavity 5211 opened inside the door core 21 and located between the two groups of telescopic cavities 512, a winding roller 5212 is rotatably installed in the equipment cavity 5211, one end of the winding roller 5212 is fixedly installed with a first transmission shaft 5213, the first transmission shaft 5213 extends to the outside of the door core 21 away from the end of the winding roller 5212 and is fixedly installed with a first control disk 514, the side walls of the equipment cavity 5211 are respectively provided with wire grooves 5215 connected to the telescopic cavity 512 on both sides, a pulling rope 5216 is wound on the surface of the winding roller 5212, the pulling rope 5216 passes through the wire groove 5215, extends into the telescopic cavity 512 and is connected to the vertical plate 514.

[0040] When it is necessary to control the door panel 2 from inside the hyperbaric oxygen chamber, the first control disk 514 is held and rotated. The first control disk 514 cooperates with the first transmission shaft 5213 to drive the winding roller 5212 to rotate in the equipment cavity 5211. The winding roller 5212 winds up the pulling rope 5216 while rotating. The pulling rope 5216 pulls the vertical plate 514 to move in the telescopic cavity 512, thereby making the clamping column 516 move as a whole into the clamping hole 511. After the clamping column 516 moves as a whole into the door core 21, the position of the door panel 2 and the door core 21 can be conveniently adjusted in the door opening 11, thereby adjusting the opening and closing state of the door opening 11.

[0041] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, as a preferred embodiment of the present invention, the external control part 522 includes a control cavity 5221 opened inside the door panel 2, the second transmission shaft 5222 is fixedly installed at one end of the winding roller 5212 away from the first transmission shaft 5213, the second transmission shaft 5222 extends into the control cavity 5221 at one end away from the winding roller 5212 and is fixedly installed with a fixed disk 5223, a second control disk 5224 is rotatably installed on the surface of the door panel 2, a plurality of groups of first magnetic blocks 5225 distributed in an annular manner are fixedly installed on a side wall of the fixed disk 5223 facing the second control disk 5224, a plurality of groups of second magnetic blocks 5226 cooperating with the first magnetic blocks 5225 are fixedly installed on a side wall of the second control disk 5225 facing the fixed disk 5223, a handle 5227 is arranged on the surface of the second control disk 5225, and a limiter 6 cooperating with the second control disk 5225 is arranged on the surface of the door panel 2.

[0042] When it is necessary to adjust the opening and closing state of the door opening 11 from outside the hyperbaric oxygen chamber, the second control disk 5225 is held and rotated. The second control disk 5225 cooperates with the second transmission shaft 5222 to control the winding roller 5212 to rotate in the equipment cavity 5211. The winding roller 5212 reels the pulling rope 5216 while rotating. The pulling rope 5216 pulls the vertical plate 514 to move in the telescopic cavity 512, thereby making the clamping column 516 move as a whole into the clamping hole 511. After the clamping column 516 moves as a whole into the door core 21, the position of the door panel 2 and the door core 21 can be conveniently adjusted in the door opening 11, thereby adjusting the opening and closing state of the door opening 11.

[0043] When the hyperbaric oxygen chamber is in use, the door panel 2 is fitted against the cabin wall 1, and the door opening 11 is in a closed state. The limiting member 6 can fix the position of the second control panel 5225 on the surface of the door panel 2, thereby effectively preventing unauthorized persons from accidentally touching the second control panel 5225 and effectively preventing the door core 21 from being released from the door opening 11.

[0044] like Figure 3 , Figure 4 , Figure 8 As shown, as a preferred embodiment of the present invention, the limit member 6 includes a plurality of groups of limit holes 61 distributed in an annular shape and opened on the surface of the second control disk 5224, and a telescopic hole 62 located on the outside of the second control disk 5224 is opened on the surface of the door panel 2, and a column 64 is slidably installed in the telescopic hole 62, and a limit rod 65 cooperating with the limit hole 61 is rotatably installed at one end of the column 64 extending outside the telescopic hole 62, and a pulling spring 63 connected to the column 64 is fixedly installed in the telescopic hole 62.

[0045] Initially, the limit rod 65 is at the outside of the second control disk 5224. When the position of the second control disk 5224 needs to be fixed, the column 64 is pulled to adjust the position of the limit rod 65, and the limit rod 65 is rotated so that the limit rod 65 rotates to the outside of the limit hole 61, and the pulling force on the column 64 is released. The pulling spring 63 pulls the column 64 toward the telescopic hole 62. At this time, the limit rod 65 is automatically inserted into the limit hole 61, and the limit rod 65 and the limit hole 61 cooperate with each other. The position of the second control disk 5224 can be conveniently fixed on the surface of the door panel 2. At this time, it can effectively prevent unauthorized people from accidentally touching the second control disk 5225, and effectively prevent the door core 21 from being released in the door opening 11.

[0046] like Figure 8 As shown, as a preferred embodiment of the present invention, the side wall of the telescopic hole 62 is provided with a plurality of positioning grooves 10 , and the side wall of the column 64 is fixedly mounted with a positioning block 101 slidably connected to the positioning groove 10 .

[0047] When the column 64 is pulled to move in the telescopic hole 62, the positioning block 101 moves synchronously in the positioning groove 10. The positioning block 101 cooperates with the positioning groove 10 to effectively prevent the column 64 from moving as a whole to the outside of the telescopic hole 62, thereby effectively improving the stability of the column 64.

[0048] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the storage assembly 72 includes two groups of vertical grooves 721 opened on the surface of the bulkhead 1 and located on both sides of the door opening 11 respectively, and multiple groups of bearing blocks 722 are slidably installed in the vertical grooves 721, and the bearing blocks 722 are made of magnetic material. The two ends of the protective rod 71 are respectively connected to the bearing blocks 722 in the two groups of vertical grooves 721, and the top of the vertical groove 721 is provided with an electromagnetic control block 723 that cooperates with the bearing blocks 722.

[0049] When the door panel 2 is in normal use, the supporting block 722 is at the top of the vertical slot 721. At this time, the electromagnetic control block 723 fixes the position of the supporting block 722 at the top of the vertical slot 721 through magnetic attraction. The supporting blocks 722 in the two groups of vertical slots 721 cooperate with each other to fix the position of the protective rod 71, and the protective rod 71 is stably located above the door opening 11.

[0050] When the pressure in the hyperbaric oxygen chamber rises abnormally and reaches the limit value, the positioning assembly 73 can automatically cut off the power supply of the electromagnetic control block 723, and the bearing block 722 moves downward in the vertical slot 721, thereby driving the protective rod 71 to move downward synchronously. Multiple sets of protective rods 71 ​​are sleeved on the outside of the door panel 2. Multiple sets of protective rods 71 ​​can further protect the door panel 2 from impact, so as to prevent the pressure difference on both sides of the bulkhead 1 from bouncing the door panel 2 and causing harm to nearby personnel. At this time, the door panel 2 can be rotated to a certain angle through the first control panel 514 or the second control panel 5224, and a gap is generated between the door panel 2 and the bulkhead 1, so that pressure relief can be carried out conveniently. Multiple sets of protective rods 71 ​​cooperate with each other, which can effectively improve the safety during pressure relief.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the positioning assembly 73 includes a pressure sensor 731 fixedly installed on the inner surface of the bulkhead 1, a controller 732 is arranged on the outer side of the pressure sensor 731, the controller 732 is electrically connected to the pressure sensor 731, the controller 732 is electrically connected to the electromagnetic control block 723, a plurality of groups of guide grooves 733 are provided on the inner side wall of the vertical groove 721, the lowest ends of the plurality of groups of guide grooves 733 are at different heights in the vertical direction, the side walls of the plurality of groups of bearing blocks 722 are respectively fixedly installed with guide blocks, and the guide blocks are slidably connected to the guide grooves 733.

[0052] When the hyperbaric oxygen chamber is in use, the pressure sensor 731 can monitor the pressure inside the hyperbaric oxygen chamber. When the pressure inside the hyperbaric oxygen chamber abnormally rises to the limit value, the pressure sensor 731 cooperates with the controller 732 to automatically power off the electromagnetic control block 723. When the electromagnetic control block 723 is powered off to release the restriction on the bearing block 722, the bearing block 722 moves vertically downward in the vertical groove 721, and the bearing block 722 drives the guide block to move synchronously in the guide groove 733. Multiple groups of guide blocks cooperate with the guide groove 733 to fix the positions of multiple groups of bearing blocks 722 at different heights in the vertical groove 721. At this time, multiple groups of protective rods 71 ​​can be sleeved on the outside of the door panel 2 in sequence.

[0053] like Figure 8 As shown, as a preferred embodiment of the present invention, a circular annular groove 8 is opened on the surface of the door panel 2, and a fixing ring 9 is rotatably installed in the annular groove 8. The fixing ring 9 extends to the outside of the door panel 2 and is fixedly connected to the second control disk 5224.

[0054] The fixing ring 9 rotates in the ring groove 8 , thereby controlling the second control disk 5224 to rotate on the surface of the door panel 2 .

[0055] The working principle of the present invention is: initially, the clamping column 516 is inserted into the clamping hole 511 on the side wall of the door opening 11, and multiple groups of clamping columns 516 and the clamping holes 511 cooperate with each other, so that the position of the door core 21 can be conveniently fixed in the door opening 11. At this time, the door opening 11 is in a closed state. When the user needs to enter the hyperbaric oxygen chamber, he / she holds the second control disk 5225 and rotates it. The second control disk 5225 cooperates with the second transmission shaft 5222 to control the winding roller 5212 to rotate in the equipment cavity 5211. The winding roller 5212 reels the pulling rope 5216 when rotating. The pulling rope 5216 pulls the vertical plate 514 to move in the telescopic cavity 512, thereby making the clamping column 516 move as a whole into the clamping hole 511. After the clamping column 516 moves as a whole into the door core 21, the position of the door panel 2 and the door core 21 can be conveniently adjusted in the door opening 11, thereby adjusting the opening and closing state of the door opening 11.

[0056] After the user enters the hyperbaric oxygen chamber, the door panel 2 is rotated so that the door core 21 moves into the door opening 11 again, and the door core 21 is fixed in the door opening 11. At this time, the door opening 11 is converted into a closed state again, and the sealing strip 3 can automatically seal the gap between the bulkhead 1 and the door panel 2. At this time, the inner cavity of the hyperbaric oxygen chamber is in a high-pressure state. During use, the sealing strip 3 can automatically seal the gap between the bulkhead 1 and the door panel 2, thereby maintaining the high-pressure environment in the hyperbaric oxygen chamber. When the sealing strip 3 is used for too long and leaks, the air in the hyperbaric oxygen chamber leaks into the cavity 42 and further flows through the air guide hole 43 to the monitoring airbag 44. At this time, the monitoring airbag 44 is filled with air and expands. After the staff outside the hyperbaric oxygen chamber sees the expansion of the monitoring airbag 44, they can promptly understand the leakage of the hyperbaric oxygen chamber, and then promptly replace the sealing strip 3, thereby effectively improving the use effect of the hyperbaric oxygen chamber. It is effectively prevented that the staff cannot detect the leakage of the hyperbaric oxygen chamber in time.

[0057] When the hyperbaric oxygen chamber is in use, the pressure sensor 731 can monitor the pressure inside the hyperbaric oxygen chamber. When the pressure inside the hyperbaric oxygen chamber abnormally rises to the limit value, the pressure sensor 731 cooperates with the controller 732 to automatically cut off the power to the electromagnetic control block 723. When the electromagnetic control block 723 is powered off to release the restriction on the bearing block 722, the bearing block 722 moves vertically downward in the vertical groove 721, and the bearing block 722 drives the guide block to move synchronously in the guide groove 733. Multiple groups of guide blocks cooperate with the guide groove 733 to fix the positions of multiple groups of bearing blocks 722 at different heights in the vertical groove 721. At this time, multiple groups of protective rods 71 ​​can be sleeved on the outside of the door panel 2 in sequence. It is prevented that the pressure difference on both sides of the bulkhead 1 will cause the door panel 2 to fly and cause harm to nearby personnel. At this time, the door panel 2 can be rotated to a certain angle through the first control panel 514 or the second control panel 5224, and a gap is generated between the door panel 2 and the bulkhead 1, which can conveniently release pressure. Multiple sets of protective rods 71 ​​cooperate with each other to effectively improve the safety during pressure relief.

[0058] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
