Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of airway foreign body removal, more particularly to a rapid airway foreign body removal device for children in emergency. BACKGROUND

[0002] In the removal of airway foreign bodies in children in emergency, the existing negative pressure suction equipment generally has the problem that the negative pressure control does not match the tolerance of the child's throat. The mucosa of the child's throat is thin and tender, and the blood vessels are rich, and the tolerance threshold of the child's throat to the change of negative pressure is much lower than that of adults. However, the traditional equipment adopts a fixed negative pressure mode, and lacks a design for dynamically adjusting the negative pressure environment according to the operation stage. If the negative pressure is too large when the initial probe is inserted, it is easy to directly adsorb the mucosa of the throat and cause damage. If the negative pressure is unstable during the removal process, it may also cause the suction to be interrupted. Although some equipment can adjust the negative pressure value, it cannot optimize the negative pressure action area in combination with the contact state of the instrument and the throat, and local negative pressure concentration often occurs, causing the child to have severe coughing, mucosal edema and other discomforts, and it is difficult to find a balance between effective suction and protection of the throat.

[0003] The existing technology lacks adaptability of the shape of the instrument under the action of negative pressure, further increasing the risk of negative pressure damage to the child's throat. The suction end of the traditional removal instrument is usually of a fixed structure, and cannot adjust the shape according to the change of the throat space. When the foreign body is adsorbed by negative pressure, the instrument and the throat wall are easy to form rigid contact, and the negative pressure force is directly transmitted to the mucosa surface. Especially when dealing with thick mucus, in order to ensure the suction effect, the negative pressure strength often needs to be increased. At this time, the instrument of fixed shape will form a sealed cavity with the throat, causing the local negative pressure to continuously rise, which not only easily causes mucosal ischemia, but also may cause relative friction between the mucosa and the instrument due to the negative pressure pulling, and aggravate the damage to the throat, which is seriously inconsistent with the demand of the child's throat for flexible operation.

[0004] In the coordinated design of negative pressure suction and foreign body transportation, the existing technology has obvious defects, which easily causes secondary problems due to negative pressure fluctuation. The high viscosity characteristics of the child's throat mucus make the transportation path prone to blockage. Under the action of negative pressure, the mucus is easy to form local aggregation or fault in the traditional straight cylinder type transportation channel, causing the negative pressure to suddenly rise or drop. When the mucus is blocked, the negative pressure will be sharply accumulated in front of the blockage point, causing continuous pressure on the mucosa of the throat. When the fault occurs, the sudden release of negative pressure may cause air flow impact, stimulating the sensitive nerves of the throat. This unstable negative pressure phenomenon not only affects the efficiency of foreign body removal, but also repeatedly stimulates the child's throat with negative pressure, increasing the operation risk, and it is difficult to meet the demand of the child's airway emergency for a gentle and stable negative pressure environment. In view of this, we propose a rapid airway foreign body removal device for children in emergency. SUMMARY

[0038] It is worth mentioning that, leakage joint 3 surface is arranged with several notches, so that the foreign body adhered in throat enters, realizes clearing effect.

[0039] It is worth mentioning that, visual system 32 is existing conventional technology, is composed of miniature camera and illumination light source, so that medical staff can clearly observe the situation of suction site when carrying out negative pressure suction operation.

[0040] The cleaning mechanism 4 comprises a conveying cylinder 41 which is tightly rotationally fitted inside the leakage connector 3, the conveying cylinder 41 is provided with a spiral groove 411 on the surface, the inner wall of the conveying cylinder 41 is provided with a ratchet 412, the inner wall of the conveying cylinder 41 is tightly rotationally fitted with a transmission rod 42 provided with a ratchet, and the ratchet on the transmission rod 42 is meshingly fitted with the ratchet 412, one end of the transmission rod 42 is hingedly connected with a curved rod 43 provided with a screw cap, and the curved rod 43 is penetrated by the side pipe 21 at one end close to the screw cap, and the side pipe 21 is tightly rotationally fitted with the curved rod 43, the end of the transmission rod 42 away from the curved rod 43 is fixedly connected with a rotating rod 44, the surface of the rotating rod 44 is annularly arranged with a sliding groove 441, the sliding groove 441 is composed of two straight sliding rails and a spiral sliding rail, the inner ring 45 is rotationally connected in the annular groove 31, the surface of the inner ring 45 is fixedly connected with a limiting hinge 451 provided with a first spring, each limiting hinge 451 is slidingly connected with an inclined top cap 452 on the surface, and the top cap 452 is insertedly fitted in the slot of the leakage connector 3, a plurality of guide sealing modules 46 are arranged on one side of the inner ring 45, any two adjacent guide sealing modules 46 are sealingly and slidingly fitted, one end of the guide sealing module 46 is sealingly and slidingly fitted with the inner ring 45, and the other end of the guide sealing module 46 is sealingly and slidingly fitted on the surface of the rotating rod 44 through a ball head sliding block, the gas bag 47 is sleeved on the end of the rotating rod 44, and the gas bag 47 is in extrusion contact with one of the guide sealing modules 46.

[0041] As shown in Figure 7 and Figures 9-10 , the plurality of guide sealing modules 46 each comprise a transmission ring 461 and an outer rotating ring 462, the transmission ring 461 is sealingly and rotationally fitted inside the outer rotating ring 462, the ball head sliding block on one of the transmission rings 461 is slidingly connected inside the sliding groove 441, except for the transmission ring 461 provided with the ball head sliding block, the remaining transmission rings 461 are annularly and fixedly connected with a plurality of bent rods 463 on one side of the inner ring 45, the bent rods 463 are inserted into the holes in the outer rotating ring 462, and the other ends of the bent rods 463 are fixedly connected with the adjacent transmission rings 461.

[0042] It is worth noting that when the gas inside the negative pressure suction pipe 1 is extracted, the flow path is increased and the space is reduced through the spiral groove 411, and the mucus in the throat of children has the characteristics of high viscosity, easy to agglomerate, poor flowability, and easy to be affected by negative pressure fluctuations, and is prone to mucus faults (i.e. discontinuous gaps in the mucus in the path, causing suction interruption or residue) due to "local flow rate unevenness and poor space adaptability" during the conveying process. Compared with the straight cylinder path, the spiral path can accurately match the mucus characteristics and avoid faults from the root by optimizing space utilization.

[0043] It is worth mentioning that the curved rod 43 is made of an alloy in the medical field, has shape memory effect and super elasticity, can restore to the original shape after bending within a certain range, and has good biocompatibility and is not easy to cause immune response of the human body; so that the hose 2 can be deformed when it is bent, and a torque is applied to the delivery cylinder 41.

[0044] It is worth mentioning that the overall diameter of the movable ring 45 and the guide sealing module 46 is distributed from large to small in turn, so that the movable ring 45 and the guide sealing module 46 can be in a lower cone state and have a gap therebetween for guiding the mucus to wind into; and can be in an upper cone state and have no gap therebetween, which can avoid discomfort caused by too high negative pressure in the throat of the child when the foreign matter is sucked away by the negative pressure suction tube 1, and is used for the protection of the throat of the child.

[0045] The device first adapts to the delicate physiological characteristics of the child's throat through multiple design, maximizes the safety of operation. The movable ring 45 and the guide sealing module 46 can realize the switching of the lower cone and the upper cone state, the gap is reserved to avoid the mucosa extrusion when the lower cone, and the upper cone is sealed without gap to stabilize the negative pressure and prevent the discomfort caused by too high local negative pressure.

[0046] As shown in Figures 9-10 The collection assembly 5 includes a plurality of top blocks 51 with inclined top surfaces, the plurality of top blocks 51 are fixedly connected in a ring array on the side surface of the transmission ring 461, the inner wall of each outer rotating ring 462 is provided with a plurality of transmission grooves 52 in a ring array, and the top block 51 is slidingly fitted in the transmission groove 52, one side of each outer rotating ring 462 is provided with a plurality of spiral holes 53 in a ring array, and the spiral hole 53 is communicated with the transmission groove 52, each spiral hole 53 is movably connected with a top rod 54 having a spiral blade inside, and the end of the top rod 54 is in movable contact with the inclined top surface of the top block 51, and the spiral blade on the top rod 54 is matched with the spiral hole 53, and the surface of each top rod 54 is sleeved with a second spring 55, and the end of the second spring 55 is fixedly connected with the inner wall of the transmission groove 52.

[0047] Specifically, by rotating the bending rod 43 clockwise or counterclockwise, the transmission rod 42 is driven to rotate, and through the meshing relationship between the ratchet teeth on the transmission rod 42 and the pawl 412, the transmission rod 42 is meshed with the conveying cylinder 41 or is in non-meshing sliding connection. When in non-meshing sliding connection, the conveying cylinder 41 does not rotate, one of the transmission rings 461 is topped at the bottom end of the sliding groove 441 by a ball head, so that the rotating rod 44 is fixed with the transmission ring 461, and the transmission ring 461 at the end is driven to rotate, and in turn drives the transmission ring 461 and the movable ring 45 to rotate. The movable ring 45 drives the top hat 452 to slide, so that the inclined surface on the top hat 452 contacts the edge of the slot on the leakage connector 3, and the top hat 452 can stick part of the mucus into the inside of the leakage connector 3. The transmission ring 461 drives the top block 51 to slide in the transmission groove 52, and through the active contact between the inclined top surface on the top block 51 and the top rod 54, the top rod 54 is pushed upwards and out, and then through the spiral hole 53 and the spiral blade on the top rod 54, the top rod 54 is rotated and pushed out, and the top rod 54 can wind and collect the mucus. When in meshing connection, the transmission rod 42 drives the conveying cylinder 41 to rotate, the top hat 452 is clamped with the slot on the leakage connector 3, so that the movable ring 45 stops rotating, and through the bending rod 463, the transmission rings 461 stop rotating. The ball head on the end transmission ring 461 slides in the sliding groove 441, so that the end transmission ring 461 moves upwards and drives the remaining transmission rings 461 to move, so that there is no gap between any two adjacent transmission rings 461, and they are in sealed sliding fit. Then the mucus between the transmission rings 461 and the conveying cylinder 41 is sucked out through the negative pressure suction pipe 1. Since the transmission rings 461 and the conveying cylinder 41 are in a negative pressure state, the guide sealing module 46 which is in sealed sliding fit with the rotating rod 44 moves upwards and squeezes and expands the air bag 47, so that the space between the transmission rings 461 and the conveying cylinder 41 is reduced, and the mucus flows out of the spiral groove 411. When the mucus passes through the spiral groove 411, since the path is long and the space is small, the mucus can be prevented from being faulted.

[0048] In terms of foreign matter removal efficiency and thoroughness, the device solves the pain points of children's high-viscosity mucus in the throat, which is easy to fault and difficult to remove. The spiral groove 411 of the conveying cylinder 41 increases the mucus flow path and optimizes the space utilization, avoiding the mucus from being interrupted due to uneven flow rate from the root; and the innovative "winding collection and negative pressure separation" dual mechanism, in the collection stage, the rotating top rod 54 actively winds the mucus, and the top hat 452 pulls the mucus from a distance into the device, and in the removal stage, the space is reduced by using the conical state and the air bag 47 is squeezed to accelerate the flow of mucus, and negative pressure is used to achieve rapid and thorough discharge, eliminating hidden dangers.

[0050] It is worth noting that the elastic rod 62 is a conventional technology, which is made of metal alloy and has elastic deformation characteristics, and is used to adjust the direction of the hose 2.

[0051] Specifically, by sliding the transmission block 63, a pulling force or a pushing force is applied to the elastic rod 62, and since the end of the elastic rod 62 is fixed to the hose 2, the elastic rod 62 is bent, and in cooperation with the visual system 32, the position of the leakage connector 3 in the throat of the child can be adjusted.

[0052] The present application improves the operation precision by visualizing and flexible adjustment, and meets the needs of emergency scenes. The integrated visual system 32 of the leakage connector 3 allows medical staff to clearly observe the position and working state of the foreign matter, avoiding blind operation; the angle adjusting assembly 6 realizes multi-directional adjustment through the deformation of the elastic rod 62, and after adjustment, the clamping plate 66 can be used to maintain stability, ensuring accurate positioning; at the same time, the device has compact structure and simplified operation, and the core action only needs to rotate the curved rod 43 and push or pull the transmission block 63, and it can be directly compatible with the existing negative pressure system of the hospital, without the need for additional equipment, which can quickly respond to emergency treatment needs, improve the convenience and universality.
