Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a tracheal intubation humidifying and fixing device. Background Art

[0002] Tracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction, etc., and is an important measure for rescuing patients with respiratory dysfunction.

[0003] In the prior art, most tracheal intubation humidifying and fixing devices fix the tracheal intubation at the nasal position by using adhesive tape. However, since the human nose is extremely prone to oiliness, the adhesiveness of the adhesive tape decreases, resulting in unstable fixing performance, and thus the tracheal intubation slips during use, which is extremely likely to have a negative impact on the oxygen supply operation of the patient and also have a negative impact on the physical health of the patient. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that due to the extremely oily nose of humans, the adhesiveness of the adhesive tape decreases, resulting in unstable fixing performance, and to propose a tracheal intubation humidifying and fixing device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A tracheal intubation humidifying and fixing device includes a strap wound around the head. A hoop for fixing the tracheal intubation is fixedly arranged on the strap. First and second fixing blocks are respectively fixedly arranged at both ends of the strap. Rubber soft pads that are movably abutted against the back of the patient's head are fixedly connected to the inner ends of the first and second fixing blocks.

[0007] A first clamping block is arranged in the first fixing block, and a second clamping block is arranged in the second fixing block. A limiting block is fixedly connected to the first clamping block, and a limiting groove corresponding to the limiting block is opened in the second clamping block. A sliding groove is opened in the limiting block, and a first spring and a first magnet are welded in the sliding groove. A second magnet with opposite poles attracting the first magnet is fixedly arranged in the limiting groove.

[0008] A first clamping rod is connected to the limiting block, a second clamping rod connected to the first clamping rod is connected to the first magnet, and a clamping groove corresponding to the connection position of the first clamping rod and the second clamping rod is opened in the second clamping block.

[0009] A first driving mechanism for driving the first clamping block to move horizontally is arranged in the first fixing block.

[0010] A second driving mechanism for driving the second clamping block to move horizontally is arranged in the second fixing block.

[0011] Preferably, a first movable through hole for slidably sleeving a first clamping block is formed in the first fixing block, and a second movable through hole for slidably sleeving a second clamping block is formed in the second fixing block.

[0012] Preferably, the first spring is welded at the inner end position of the sliding groove, and the first magnet is slidably sleeved in the sliding groove.

[0013] Preferably, the first clamping rod is pin-connected to the limiting block, and two ends of the second clamping rod are respectively pin-connected to the first clamping rod and the first magnet.

[0014] Preferably, the first driving mechanism includes a driving rod arranged on the first clamping block. A second spring is welded between the driving rod and the first clamping block. A guiding groove is formed in the inner wall of the first clamping block. A guiding block and a third spring are welded in the guiding groove. A traction rod is connected between the guiding block and the driving rod. A fixing plate fixedly connected to the first clamping block is fixedly connected to the guiding block.

[0015] Preferably, the second spring is movably sleeved on the driving rod, and a guiding through hole for movably sleeving the driving rod is formed in the first clamping block.

[0016] Preferably, the guiding block is slidably sleeved in the guiding groove. The third spring is welded at the outer end position of the guiding groove. Two ends of the traction rod are respectively pin-connected to the guiding block and the driving rod.

[0017] Preferably, the second driving mechanism includes a rotating shaft rotatably installed in the second fixing block through a bearing. A driving gear is fixedly sleeved on the rotating shaft. A driven rack meshed with the driving gear is fixedly arranged on the second clamping block.

[0018] Preferably, a rotating plate is fixedly connected to the outer end of the rotating shaft, and the driven rack is arranged at the outer end position of the second clamping block.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. The present invention winds the binding band around the patient's head, thereby avoiding the negative impact on the patient's medical operation caused by the detachment of the fixator during use. The driving rod drives the guiding block to perform a horizontal movement through the traction rod. The guiding block drives the first clamping block to move outward through the fixing plate. The first clamping block drives the limiting block to enter the limiting groove. Through the magnetic attraction force between the first magnet and the second magnet, the first magnet moves in the sliding groove towards the second magnet. The first magnet drives the first clamping rod and the second clamping rod to deflect, and the connection part of the two enters the clamping groove, thereby realizing the fixed connection of the binding band, which helps to improve the stability of the fixator during use.

[0021] 2. In the present invention, the rotating shaft drives the second clamping block to move towards the inner end of the second fixing block through the meshing connection between the driving gear and the driven rack, thereby completing the disassembly of the strap, which helps to improve the convenience of disassembling the fixator.

[0022] In summary, in the present invention, by winding the strap around the patient's head, the fixator is prevented from falling off during use, which has a negative impact on the patient's medical operation, and helps to ensure the safety of the patient during the medical operation. The driving rod drives the guide block to move horizontally through the traction rod. The guide block drives the first clamping block to move outwards through the fixing plate. The first clamping block drives the limiting block to enter the limiting groove. Through the magnetic attraction between the first magnet and the second magnet, the first magnet moves towards the second magnet in the sliding groove. The first magnet drives the first clamping rod and the second clamping rod to deflect, and the connection part of the two enters the clamping groove, thereby realizing the fixed connection of the strap, which helps to improve the stability of the fixator during use. By rotating the rotating shaft, the second clamping block can be driven to move through the driving gear and the driven rack, so that the limiting block disengages from the limiting groove, and the first magnet and the second magnet no longer attract each other, which helps to improve the convenience of disassembling the fixator.

DETAILED DESCRIPTION OF THE INVENTION

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Referring to Figures 1-4 , a tracheal intubation humidification fixator includes a strap 1 wound around the head. A hoop 2 for fixing the tracheal intubation is fixedly arranged on the strap 1. It should be noted that: the hoop 2 is a mature existing technology, so it will not be elaborated. A humidification component is provided on the tracheal intubation. The specific specifications of the humidification component need to be selected according to the actual use of the device. The specific selection calculation method uses the existing technology in the field, so it will not be elaborated. First fixing blocks 3 and second fixing blocks 4 are respectively fixedly arranged at both ends of the strap 1;

[0030] The inner ends of the first fixing block 3 and the second fixing block 4 are fixedly connected with rubber soft pads 5 that are movably abutted against the back of the patient's head. The rubber soft pads 5 are made of rubber. Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external force, and can return to its original state after removing the external force. The back of the patient's head can be protected through the rubber soft pads 5, which helps to ensure the comfort of the patient during use;

[0031] A first clamping block 6 is arranged in the first fixing block 3. A first movable through hole for slidably sleeving the first clamping block 6 is opened on the first fixing block 3. The first movable through hole can provide a moving space for the movement of the first clamping block 6. A second clamping block 7 is arranged in the second fixing block 4. A second movable through hole for slidably sleeving the second clamping block 7 is opened on the second fixing block 4. The second movable through hole can provide a moving space for the movement of the second clamping block 7;

[0032] A limiting block 8 is fixedly connected to the first clamping block 6. A limiting groove 9 corresponding to the limiting block 8 is opened on the second clamping block 7. The limiting block 8 can enter the limiting groove 9 to facilitate subsequent automatic buckling operations;

[0033] The limiting block 8 is provided with a sliding groove 10. A first spring 11 and a first magnet 12 which are welded together are arranged in the sliding groove 10. The first spring 11 is welded at the inner end position of the sliding groove 10. The first magnet 12 is slidably sleeved in the sliding groove 10. Due to the guiding and limiting effect of the sliding groove 10, the first magnet 12 can only move in the sliding groove 10. Due to the elastic force of the first spring 11, the first magnet 12 can be reset when it is separated from the attracting effect of the second magnet 13. A second magnet 13 which is attracted to the first magnet 12 with opposite polarity is fixedly arranged in the limiting groove 9. It should be noted that: the first magnet 12 and the second magnet 13 are permanent magnets, and their type is neodymium iron boron magnet. It has extremely high magnetic properties, its maximum magnetic energy product is more than 10 times higher than that of ferrite, its mechanical processing performance is quite good, the highest working temperature can reach 200 °C, and its texture is hard, its performance is stable, and it has good cost performance;

[0034] The limiting block 8 is pin-connected with a first clamping rod 14. The first magnet 12 is pin-connected with a second clamping rod 15 which is pin-connected with the first clamping rod 14. The second clamping block 7 is provided with a clamping groove 16 corresponding to the connection position of the first clamping rod 14 and the second clamping rod 15. By the connection position of the first clamping rod 14 and the second clamping rod 15 entering the clamping groove 16, the fixed connection between the limiting block 8 and the limiting groove 9 is completed in this way;

[0035] A first driving mechanism for driving the first clamping block 6 to move horizontally is arranged in the first fixing block 3. By driving the first clamping block 6 to move through the first driving mechanism, the first clamping block 6 can drive the limiting block 8 into the limiting groove 9;

[0036] Further explanation: The first driving mechanism includes a driving rod 17 arranged on the first clamping block 6. The first clamping block 6 is provided with a guiding through hole for movably sleeving the driving rod 17. The guiding through hole can provide a moving space for the movement of the driving rod 17;

[0037] A second spring 18 is welded between the driving rod 17 and the first clamping block 6. The second spring 18 is movably sleeved on the driving rod 17. Due to the elastic force of the second spring 18, the driving rod 17 can be reset when it is not squeezed;

[0038] A guiding groove 19 is arranged on the inner wall of the first clamping block 6. A guiding block 20 and a third spring 21 which are welded together are arranged in the guiding groove 19. The guiding block 20 is slidably sleeved in the guiding groove 19. The third spring 21 is welded at the outer end position of the guiding groove 19. Due to the guiding and limiting effect of the guiding groove 19, the guiding block 20 can only move in the guiding groove 19, which helps to ensure that the movement track of the guiding block 20 is relatively fixed. Due to the elastic force of the third spring 21, the guiding block 20 can be reset when it is not squeezed;

[0039] A draw bar 22 is pin-connected between the guiding block 20 and the driving rod 17, and a fixing plate 23 fixedly connected to the first clamping block 6 is fixedly connected to the guiding block 20;

[0040] A second driving mechanism for driving the second clamping block 7 to move horizontally is arranged in the second fixing block 4. By driving the second clamping block 7 to move, the limiting block 8 can be separated from the limiting groove 9, so as to realize the separation operation of the limiting block 8 and the limiting groove 9, which helps to improve the disassembly efficiency of the tracheal intubation humidification fixator;

[0041] Further explanation: The second driving mechanism includes a rotating shaft 24 rotatably installed in the second fixing block 4 through a bearing. A rotating plate is fixedly connected to the outer end of the rotating shaft 24. The setting of the rotating plate helps to improve the comfort of the user;

[0042] A driving gear 25 is fixedly sleeved on the rotating shaft 24. A driven rack 26 meshed with the driving gear 25 is fixedly arranged on the second clamping block 7. The driven rack 26 is arranged at the outer end position of the second clamping block 7 and is driven by a gear-rack mechanism. The transmission mechanism has a stable structure.

[0043] The functional principle of the present invention can be described by the following operation method:

[0044] The tracheal intubation is fixed and limited by the hoop 2. The strap 1 is wound around the patient's head. The driving rod 17 is pressed, and the second spring 18 is driven to contract. The driving rod 17 drives the draw bar 22 to deflect. The draw bar 22 drives the guiding block 20 to move horizontally in the guiding groove 19. The guiding block 20 squeezes the third spring 21. The guiding block 20 drives the fixing plate 23 to move. The fixing plate 23 drives the first clamping block 6 to move outwards. The first clamping block 6 drives the limiting block 8 to enter the limiting groove 9. Through the opposite-pole attraction of the first magnet 12 and the second magnet 13, the first magnet 12 moves towards the outer end of the sliding groove 10. The first magnet 12 drives the second clamping rod 15 to deflect, so that the connection part of the first clamping rod 14 and the second clamping rod 15 enters the clamping groove 16;

[0045] When it is necessary to loosen the strap 1, the rotating shaft 24 is rotated. The rotating shaft 24 drives the driving gear 25 to rotate. The driving gear 25 drives the driven rack 26 to move inwards. The driven rack 26 drives the second clamping block 7 to move towards the inner end of the second fixing block 4.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
