Description

Technical Field

[0001] This invention belongs to the field of emergency ventilator technology, specifically referring to a respiratory assist device for emergency treatment of airway trauma in the field. Background Technology

[0002] In field environments, first responders often wear gloves and operate in low light or obstructed conditions. Traditional snap-fit ​​or threaded connections have the following drawbacks:

[0003] Alignment difficulties: It is difficult to quickly and accurately align the interface by touch.

[0004] Unclear connection status: There is a lack of clear feedback on whether the connection is in place, which can easily lead to ventilation failure due to unreliable connection.

[0005] Cumbersome to operate: It is very difficult to operate small or complex locking mechanisms while wearing gloves. Summary of the Invention

[0006] In response to the above situation and to overcome the shortcomings of existing technologies, this solution aims to achieve a quick, accurate, and reliable connection under "blind operation" through a quick-release system that integrates magnetic coding guidance, mechanical ratchet lock, tactile and auditory feedback, and anti-loosening structure. It also ensures that the operator is clearly aware of the connection status through multi-level feedback. When the ratchet teeth of the fixed ratchet and the rotating ratchet engage, obvious tactile and auditory feedback is generated, which allows for precise determination of the rotation range when tightening the handle.

[0007] The technical solution adopted by the present invention is as follows: The present invention proposes a respiratory assist device for field airway trauma emergency treatment, including a magnetic code disk guiding assembly, a connector assembly, a squeeze fastening assembly, a ratchet locking assembly, a fixed connector and a main unit. The magnetic code disk guiding assembly is disposed on the fixed connector, the connector assembly is disposed in the magnetic code disk guiding assembly, the squeeze fastening assembly is disposed on the magnetic code disk guiding assembly and the connector assembly, the ratchet locking assembly is disposed on the fixed connector, and the fixed connector is disposed on one side of the main unit.

[0008] Furthermore, the magnetic code disk guiding assembly includes a magnetic code disk, a limiting shell, and magnetic guide blocks. The limiting shell is fixed to the fixed connector, the magnetic code disk is fixed to the limiting shell, and the magnetic guide blocks are evenly distributed in a ring on the connector assembly. The magnetic code disk is provided with a guide magnet. When the magnetic guide block is aligned with the guide magnet with opposite magnetic poles, the magnetic guide block is exactly at the correct angle.

[0009] By guiding the magnetic guide block with a magnet, the connector can be angularly guided, allowing the magnetic guide block to automatically adjust its direction during insertion, thus avoiding the problem of the magnetic guide block easily hitting the limiting block when inserted.

[0010] Furthermore, the connector assembly includes a connector, a handle, and an air supply hose. The magnetic guide blocks are evenly distributed in a ring and fixed to the outside of the connector. The connector has a sandwich section, and the air supply hose is located in the sandwich section.

[0011] Preferably, the compression fastening assembly includes an arc-shaped pressure plate and a limiting block. The connector head is provided with spring plates evenly distributed in a ring. The arc-shaped pressure plate is fixed to the spring plates. The limiting block is fixed to the inner wall of the limiting shell. The limiting block is provided with a clearance groove that matches the magnetic guide block. The limiting block is also provided with an arc-shaped groove that matches the arc-shaped pressure plate.

[0012] After the magnetic guide block is inserted, rotating the handle can not only rotate the magnetic guide block away from the clearance groove and complete the axial locking of the connector, but also compress and fix the air supply hose through the compression of the arc-shaped pressure plate by the arc groove, thereby preventing the air supply hose from falling out of the interlayer.

[0013] Preferably, the handle is provided with a connecting rod, and the handle is fixedly connected to the arc-shaped pressure plate through the connecting rod.

[0014] Furthermore, the ratchet locking assembly includes a fixed ratchet and a rotating ratchet. The fixed ratchet is fixed to the fixed joint, and the rotating ratchet is rotatably disposed in the limiting housing. The fixed ratchet and the rotating ratchet can only rotate in one direction. The rotating ratchet is provided with a slot that matches the magnetic guide block.

[0015] By coordinating the fixed ratchet and the rotating ratchet, the locked connector can be rotated to a limited position, preventing it from rotating back under the action of the spring force.

[0016] When the ratchet engages with the fixed ratchet and the rotating ratchet, there is clear auditory and tactile feedback, which allows for precise determination of the rotation range when tightening the handle.

[0017] Furthermore, the fixed joint consists of a flange and a pipe, the pipe being snapped into the main unit, and the flange being fixedly connected to the side of the main unit.

[0018] Preferably, the limiting housing is fixed to the flange, the connector is sleeved on the pipe, and the rotating ratchet is rotatably mounted on the pipe.

[0019] Furthermore, the main unit is equipped with a medicine compartment, the pipeline section and the medicine compartment are connected in a continuous manner, and the end of the air supply hose is connected to a breathing mask.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] (1) By guiding the magnetic guide block with a guide magnet, the connector can be angularly guided, so that the magnetic guide block can automatically adjust its own direction during the pushing process, thereby avoiding the problem of the magnetic guide block hitting the limit block when it is inserted.

[0022] (2) After the magnetic guide block is inserted, rotating the handle can not only rotate the magnetic guide block away from the relief groove and complete the axial locking of the connector, but also complete the compression and fixation of the air supply hose through the compression of the arc-shaped pressure plate by the arc groove, thereby preventing the air supply hose from falling out of the interlayer.

[0023] (3) By cooperating between the fixed ratchet and the rotating ratchet, the locking connector can be rotated and limited to prevent it from rotating under the action of the elastic force.

[0024] (4) When the ratchet meshes between the fixed ratchet and the rotating ratchet, there is obvious feedback in both hearing and touch. Through this feedback, the rotation amplitude when tightening the handle can be accurately determined. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] like Figures 1-10 As shown, the present invention proposes a respiratory assist device for field airway trauma first aid, including a magnetic code disk guiding assembly 1, a connector assembly 2, a compression fastening assembly 3, a ratchet locking assembly 4, a fixing connector 5, and a main unit 6. The magnetic code disk guiding assembly 1 is disposed on the fixing connector 5, the connector assembly 2 is disposed in the magnetic code disk guiding assembly 1, the compression fastening assembly 3 is disposed on the magnetic code disk guiding assembly 1 and the connector assembly 2, the ratchet locking assembly 4 is disposed on the fixing connector 5, and the fixing connector 5 is disposed on one side of the main unit 6.

[0041] The magnetic code disk guide assembly 1 includes a magnetic code disk 11, a limiting shell 12, and magnetic guide blocks 13. The limiting shell 12 is fixed to the fixed connector 5, the magnetic code disk 11 is fixed to the limiting shell 12, and the magnetic guide blocks 13 are evenly distributed in a ring on the connector assembly 2. The magnetic code disk 11 is provided with a guide magnet 111. When the magnetic guide block 13 is aligned with the guide magnet 111 with opposite magnetic poles, the magnetic guide block 13 is exactly at the correct angle.

[0042] By guiding the magnetic guide block 13 with the guide magnet 111, the connector 21 can be angularly guided, so that the magnetic guide block 13 can automatically adjust its own direction during the pushing process, thereby avoiding the problem that the magnetic guide block 13 is prone to hitting the limiting block 32 when inserted.

[0043] The connector assembly 2 includes a connector 21, a handle 22, and an air supply hose 23. Magnetic guide blocks 13 are evenly distributed in a ring and fixed to the outside of the connector 21. The connector 21 is provided with a sandwich section 211, and the air supply hose 23 is located in the sandwich section 211.

[0044] The compression fastening assembly 3 includes an arc-shaped pressure plate 31 and a limiting block 32. The connector 21 has spring portions 212 evenly distributed in a ring. The arc-shaped pressure plate 31 is fixed to the spring portions 212. The limiting block 32 is fixed to the inner wall of the limiting shell 12. The limiting block 32 is provided with a clearance groove 321 that matches the magnetic guide block 13. The limiting block 32 is also provided with an arc-shaped groove 322 that matches the arc-shaped pressure plate 31.

[0045] After the magnetic guide block 13 is inserted, rotating the handle 22 can not only rotate the magnetic guide block 13 away from the clearance groove 321 and complete the axial locking of the connector 21, but also complete the compression and fixation of the air supply hose 23 by squeezing the arc-shaped pressure plate 31 through the arc-shaped groove 322, thereby preventing the air supply hose 23 from falling out of the interlayer 211.

[0046] The handle 22 is provided with a connecting rod, and the handle 22 is fixedly connected to the arc-shaped pressure plate 31 through the connecting rod.

[0047] The ratchet locking assembly 4 includes a fixed ratchet 41 and a rotating ratchet 42. The fixed ratchet 41 is fixed to the fixed joint 5, and the rotating ratchet 42 is rotatably disposed in the limiting housing 12. The fixed ratchet 41 and the rotating ratchet 42 can only rotate in one direction. The rotating ratchet 42 is provided with a slot 421 that matches the magnetic guide block 13.

[0048] The engagement between the fixed ratchet 41 and the rotating ratchet 42 allows for rotational limiting of the locked connector 21, preventing it from rotating under the action of elastic force.

[0049] When the ratchet meshes between the fixed ratchet 41 and the rotating ratchet 42, obvious auditory and tactile feedback is generated, which allows for precise determination of the rotation amplitude when the handle 22 is tightened.

[0050] The fixed joint 5 consists of a flange part 51 and a pipe part 52. The pipe part 52 is snapped into the main unit 6, and the flange part 51 is fixedly connected to the side of the main unit 6.

[0051] The limiting housing 12 is fixed to the flange 51, the connector 21 is sleeved on the pipe 52, and the rotating ratchet 42 is rotatably mounted on the pipe 52.

[0052] The main unit 6 is equipped with a medicine compartment 61, and the pipeline section 52 and the medicine compartment 61 are connected in a continuous manner. The end of the air supply hose 23 is connected to the breathing mask.

[0053] like Figure 11 As shown, the number of guide magnets 111 is twice the number of magnetic guide blocks 13. When the magnetic guide blocks 13 are aligned with the slot portion 421, the guide magnets 111 and the magnetic guide blocks 13 are at opposite angles and have opposite magnetic poles (attractive force). The magnetic poles of the remaining guide magnets 111 are the same as those of the magnetic guide blocks 13 (repulsive force). When the magnetic guide blocks 13 are not aligned with the slot portion 421, under the combined action of magnetic attraction and repulsion, the magnetic guide blocks 13 tend to align with the slot portion 421.

[0054] In practical use, the user first needs to hold the handle 22 and insert the connector 21 into the limiting shell 12. When the magnetic guide block 13 moves to the magnetic code disk 11, if the magnetic guide block 13 is aligned with the slot 421, the guide magnet 111 and the magnetic guide block 13 are at opposite angles and have opposite magnetic poles (attractive force). The magnetic poles of the other guide magnets 111 are the same as those of the magnetic guide block 13 (repulsive force). If the magnetic guide block 13 is not aligned with the slot 421, under the combined action of magnetic attraction and repulsion, the magnetic guide block 13 tends to align with the slot 421.

[0055] When the magnetic guide block 13 is aligned with the slot 421, the magnetic guide block 13 can pass through the clearance groove 321 and enter the slot 421. Then, rotating the handle 22 will cause the connector 21 and the magnetic guide block 13 to rotate together.

[0056] On the one hand, the magnetic guide block 13 will rotate away from the clearance groove 321. The axial limitation of the limiting block 32 can block the magnetic guide block 13 and prevent the connector 21 from coming out.

[0057] On the other hand, the arc groove 322 will gradually squeeze the rotating arc pressure plate 31. By squeezing the arc pressure plate 31, the clamping force of the arc pressure plate 31 on the air supply hose 23 can be increased, thereby locking the air supply hose 23 and preventing the air supply hose 23 from coming out.

[0058] Furthermore, the magnetic guide block 13 enters the slot 421 and drives the rotating ratchet 42 to rotate. The squeezing force of the arc groove 322 on the arc pressure plate 31 causes the connector 21 to have a tendency to rotate in the opposite direction. However, by fixing the ratchet 41 to limit the rotation direction of the rotating ratchet 42, the connector 21 can be prevented from reversing and resetting.

[0059] When the clamping force between the arc groove 322 and the arc pressure plate 31 reaches a certain level, the connection and locking of the air supply hose 23 can be completed.

[0060] When the ratchet meshes between the fixed ratchet 41 and the rotating ratchet 42, obvious auditory and tactile feedback is generated, which allows for precise determination of the rotation amplitude when the handle 22 is tightened.

[0061] When it is necessary to disassemble the air supply hose 23, simply continue to rotate the handle 22 with greater force. When the magnetic guide block 13 moves to the position of the next clearance groove 321, the connector 21 can be pulled out.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0063] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
