The existing simple respirator is convenient to assemble and replace the air bags, the air bags are connected with the communicating structure in a mode of interference fit between pipelines, and the air bags can be connected or detached through direct plugging, so that medical staff is allowed to quickly assemble the respirator, and the preparation time of rescue work is shortened. However, the connection mode between the air bag and the communication structure is only fixed by virtue of friction force between the two pipelines, so that the defect of unstable connection exists, and the air bag and the communication structure can be accidentally separated due to the action of external force on the respirator, thereby bringing adverse effects to the work of medical staff.
Based on the above, in order to improve the technical problem that the connection between the air bag and the communication structure in the related art is not firm, the air bag and the communication structure can be accidentally separated due to the action of external force on the respirator, and adverse effects are brought to the work of medical staff, the following scheme is provided in the embodiment of the application.
The application is described in further detail below in connection with fig. 1-7.
The embodiment discloses a medical respirator, which comprises a face mask 1, an elastic air bag 2 and a communication component 3 used for communicating the face mask 1 and the elastic air bag 2, wherein a first connector 31 is arranged at one end, connected with an air outlet of the elastic air bag 2, of the communication component 3, a second connector 21 is arranged at the air outlet of the elastic air bag 2, one end, far away from the elastic air bag 2, of the second connector 21 is inserted into the first connector 31, at least one clamping column 211 is fixedly arranged on the outer peripheral surface of the second connector 21, an L-shaped clamping groove 311 matched with the clamping column 211 is formed in a penetrating manner on the inner peripheral surface of the first connector 31, the clamping column 211 is clamped in the L-shaped clamping groove 311, and a sealing piece used for sealing the first connector 31 and the second connector 21 and applying thrust force to the second connector 21, far away from the first connector 31, is arranged in the first connector 31.
As described above, the seal may be an elastic seal ring, an abutting seal structure composed of a bellows and a spring, or the like, and may abut against the end of the second connector 21 to form a seal after the second connector 21 is inserted into the first connector 31, thereby applying elastic resistance to the second connector 21.
In this way, when connecting the elastic air bag 2 and the communication module 3, the second connector 21 is inserted into the first connector 31, and the respective engagement posts 211 are inserted into the openings of the corresponding L-shaped engagement grooves 311. Then, the second connector 21 is continuously inserted, after the clamping post 211 is inserted into the corner of the L-shaped clamping groove 311, the first connector 31 is kept fixed, the second connector 21 is rotated, the clamping post 211 continuously slides along the bending part of the L-shaped clamping groove 311, and after the second connector 21 and the clamping post 211 are rotated for a certain angle, the second connector 21 is loosened. At this time, the end of the second connector 21 located inside the first connector 31 is abutted against the sealing member to form a seal, and the sealing member applies a pushing force to the second connector 21 to keep away from the first connector 31, so that the clamping column 211 is abutted against the inner wall of the L-shaped clamping groove 311, and the clamping column 211 and the second connector 21 are fixed on the first connector 31. The clamping post 211 can effectively prevent the second connector 21 from sliding relative to the first connector 31.
The connection mode of the communication assembly 3 and the elastic air bag 2 can complete the rapid and stable assembly of the respirator only by pushing and rotating the second connector 21 by medical staff, and allows the medical staff to be rapidly put into rescue work. Therefore, the connection between the air bag 2 and the communication component 3 can be more stable under the condition of ensuring the rapid assembly effect of medical staff on the respirator.
The elastic air bag 2 is detachably connected with the communication assembly 3, which means that the elastic air bag 2 and the communication assembly 3 can be stored separately when the respirator is stored. The specifications of the elastic air bag 2 can be produced into a plurality of specifications according to actual requirements. When the respirator is required to be prepared for rescue work, a medical staff can prepare a certain number of universal communication assemblies 3 and then prepare a plurality of elastic air bags 2 with different specifications. When the respirator is used, the elastic air bag 2 which is needed to be used is selected, and then the second connector 21 on the elastic air bag 2 is connected with the first connector 31 on the communication component 3. The communication component 3 enables the elastic air bag 2 to be communicated with the mask 1, and when the elastic air bag 2 is pressed, the air inside the elastic air bag 2 can be pressed into the mask 1 through the communication component 3, so that the breathing of a patient is assisted.
Optionally, in some embodiments, referring to fig. 4 to 7, a mating groove 312 that mates with the clamping post 211 is formed on a side of the l-shaped clamping groove 311 facing the elastic air bag 2 along a radial portion of the first connector 31, and the clamping post 211 is clamped inside the mating groove 312.
So set up, the shape of mating groove 312 and the shape looks adaptation of joint post 211, rotate joint post 211 to the position of aligning mating groove 312 after, loosen second connector 21, the sealing member promotes second connector 21 and joint post 211 removal, makes joint post 211 card go into inside mating groove 312. The engaging groove 312 can prevent the second connector 21 from blocking the rotation of the second connector 21 when the second connector 21 is subject to the external force to generate the rotation trend relative to the first connector 31. The second connector 21 and the first connector 31 are prevented from being loosened.
Optionally, referring to fig. 4, a first sealing surface 313 is formed on an inner wall of the first connecting head 31, a second sealing surface 212 is formed at an end of the second connecting head 21 near the first sealing surface 313, the sealing member includes a first elastic sealing ring 41, and the first elastic sealing ring 41 is disposed between the first sealing surface 313 and the second sealing surface 212 and abuts against the first sealing surface 313 and the second sealing surface 212, respectively.
The first elastic seal ring 41 may be disposed between the first seal surface 313 and the second seal surface 212 in various manners, and may be fixedly disposed on either one of them. For example, an annular groove adapted to the shape of the first elastic sealing ring 41 may be formed in the first sealing surface 313, and then the first elastic sealing ring 41 is interference fit into the annular groove.
In this manner, after the second joint head 21 is inserted into the first joint head 31, the second sealing surface 212 abuts against one surface of the first elastic seal ring 41, and the other surface thereof is pressed against the first sealing surface 313, so that a seal is formed between the first sealing surface 313 and the second sealing surface 212, thereby preventing leakage of air flow. Meanwhile, when the first elastic sealing ring 41 is pressed, elastic force is applied to the second sealing surface 212, so that the clamping column 211 is fixed inside the L-shaped clamping groove 311.
In some embodiments, referring to fig. 4 and 5, a first conical surface 314 is formed on an inner wall of the first connector 31, a second conical surface 213 matching with the first conical surface 314 is formed on an outer wall of the second connector 21, and the sealing member further includes a second elastic sealing ring 42, wherein the second elastic sealing ring 42 is disposed between the first conical surface 314 and the second conical surface 213 and is respectively abutted against the first conical surface 314 and the second conical surface 213.
The second elastic sealing ring 42 may be assembled in the same manner as the first elastic sealing ring 41. After the second connector 21 is inserted into the first connector 31 and locked, the second elastic sealing ring 42 applies a pushing force to the second conical surface 213, so as to increase the resistance of the second connector 21 and make the clamping between the clamping post 211 and the L-shaped clamping slot 311 more stable. And a second sealing layer is formed between the first conical surface 314 and the second conical surface 213, so that the sealing effect between the first connector 31 and the second connector 21 is enhanced. Through the cooperation of the first conical surface 314 and the second conical surface 213, the first conical surface 314 can also apply a component force along the radial direction of the second connector 21 to the second connector 21 through the second elastic sealing ring 42, so that the position of the second connector 21 is centered, the shaking amplitude between the second connector 21 and the first connector 31 is reduced, and the cooperation effect between the two is improved.
In some embodiments, referring to fig. 3, one end of the communication component is communicated with the air inlet of the mask through a breather valve 5, and the air outlet pipe of the breather valve 5 is inserted into the air inlet pipe of the mask 1 and is in interference fit with the inner wall of the air inlet pipe of the mask 1.
So set up, set up face guard 1 as detachably connects on the intercommunication subassembly 3, the face guard 1 of the different specifications that can be applicable to the patient is selected when assembling the respirator, makes the application scope of respirator more extensive.
Optionally, in some embodiments, referring to fig. 1 and 2, the communication assembly 3 further includes a three-way valve 32 and two communication pipes 33, wherein an air inlet of the three-way valve 32 is communicated with an air outlet of the first connection head 31, one ends of the two communication pipes 33 are respectively communicated with two air outlets of the three-way valve 32, the other ends of the two communication pipes are respectively communicated with an air inlet of the breather valve 5, one pressure relief valve 331 is arranged on each of the two communication pipes 33, and preset pressure thresholds of the two pressure relief valves 331 are different.
Because patients of different ages have different lung bearing capacities when using the respirator, the pressure safety valve 331 with different pressure thresholds is needed to ensure that the pressure applied by the respirator to the lungs of the patient is not higher than the safety range. The number of the communicating pipes 33 can be further increased according to practical situations, and meanwhile, the three-way valve 32 can be changed into a valve with more channels, so long as the air outlet of the first connecting head 31 is ensured to be communicated with any communicating pipe 33 and disconnected with other communicating pipes 33.
After the respirator is assembled by medical staff, a communication channel matched with the elastic air bag 2 is needed to be selected. If the pressure threshold set by the pressure relief valves 331 installed on the two communicating pipes 33 is suitable for children and adults, respectively, the pressure threshold preset by the pressure relief valves 331 adapted for adults is higher than that of children, and the medical staff can adjust the three-way valve 32 to enable the first connecting joint 31 to be communicated with only one adapted communicating pipe 33. This allows the pressure relief valve 331 to provide the desired protective effect for the patient.
Alternatively, referring to fig. 1 to 5, one end of the corresponding communication tube 33 of the two pressure relief valves 331, which is smaller than the preset pressure threshold, near the breather valve 5 is provided with a check valve for preventing the gas inside the intake port of the breather valve 5 from flowing into the inside of the communication tube 33.
So configured, when the elastic bag 2 communicates with one communication tube 33 having a higher preset pressure threshold, if both communication tubes 33 communicate with the intake port of the breather valve 5, the gas inside the total communication chamber can enter the inside of the low pressure threshold communication tube 33, and when the pressure of the gas inside the communication chamber is higher than the bottom pressure threshold, the gas overflows from the pressure relief valve 331, resulting in failure to maintain the desired high pressure inside the communication chamber. This check valve can block gas from leaking from the inside of the low-pressure threshold communication pipe 33 in this case, thereby avoiding the interference between the operations of the two pressure relief valves 331.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
