Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a portable humidifying and warming device for tracheotomy. Background Art

[0002] An artificial airway is a gas passage established by inserting a catheter through the mouth, nose, or tracheotomy into the trachea to ensure the patency of the patient's airway. It is an effective connection established among the airway, air, and other gas sources. Establishing and using an artificial airway is an important method for rescuing critically ill patients. The main purposes of establishing an artificial airway are to facilitate the application of mechanical ventilation or pressurized oxygen supply; to keep the respiratory tract unobstructed and facilitate the removal of airway secretions or foreign bodies; to effectively prevent the aspiration of vomitus and oral and nasal secretions into the lungs for patients with unclear consciousness, especially coma patients; to increase the effective alveolar ventilation volume, reduce airway resistance, and improve the efficiency of respiratory gas exchange; and to facilitate atomization humidification and airway drug administration.

[0003] For patients with tracheotomy, there is a tracheotomy cannula in the larynx. When performing tracheal humidification, the tracheotomy cannula needs to be connected to a nebulizer. However, the nebulizer is large in size and not easy to carry. For the convenience of carrying, a nebulizing cup can also be used for humidification. The existing nebulizing cup can filter different particle sizes of nebulized droplets by adjusting the length of the sleeve-shaped baffle during use, and then mix the filtered nebulized droplets with air and inhale them by the patient. However, only adjusting the particle size by filtration will result in a decrease in the droplet content in the inhaled gas of the patient, leading to a reduction in the effect and efficiency of tracheal humidification.

[0011] Specifically, the dispersion component includes a first dispersion plate symmetrically and fixedly arranged on the air duct, a second dispersion plate symmetrically arranged on the air duct, and an inclined groove fixedly arranged on the first dispersion plate and the second dispersion plate.

[0012] Specifically, the support component includes a plurality of support plates fixedly arranged on the conical sleeve and support blocks fixedly arranged on the support plates.

[0013] Specifically, the limiting component includes a plurality of limiting holes rotationally arrayed on the first cup body, a plurality of third chutes fixedly arranged on the adjusting ring, limiting heads slidably arranged on the third chutes, and a first spring with one end fixedly arranged on the limiting head and the other end fixedly arranged on the cover body.

[0014] Specifically, the linkage assembly includes a plurality of fourth chutes fixedly arranged on the cover plate, a first rack slidably arranged on the fourth chutes, a first gear rotatably arranged on the cover plate and meshing with the first rack, a second gear rotatably arranged on the cover plate and meshing with the first rack, a plurality of fifth chutes fixedly arranged on the cover plate, a second bracket slidably arranged on the fifth chutes and fixedly connected to the atomizing rod, a second rack fixedly arranged on the second bracket, and an engaging device arranged on the first limiting rod and the second convex ring.

[0016] The beneficial effects of the present invention are:

[0017] (1) It is small in size and easy to carry. It can be externally connected to a compressed air pipe, which is convenient for use when going out.

[0018] (2) The existing atomizing cup cannot adjust the atomizing particle size during atomization. It can only be adjusted by filtering after the atomized droplets are mixed with air. Suppose that after atomization, 30% of the liquid has small particle size, 40% has medium particle size, and 30% has large particle size. These atomized droplets are mixed with air, and finally form a mixture of 50% air and 50% atomized droplets without filtration. The existing atomizing cup can filter the mixture and filter out the large particle size droplets larger than the set value. Therefore, the proportion of atomized droplets in the filtered mixture is less than 50%. Since the existing atomizing cup cannot adjust the particle size during atomization, if a smaller filtration value is set, the proportion of atomized droplets in the mixture will be further reduced, resulting in very little atomized droplet content in the mixture inhaled by the patient, reducing the tracheal humidification effect and prolonging the humidification time, thus reducing the humidification efficiency. That is, the existing atomizing cup will reduce the humidification effect and efficiency when adjusting the particle size. Therefore, an atomizing cup that can adjust the atomizing particle size is needed to synchronously adjust the filtration particle size and the atomizing particle size, so that the proportion of air and atomized droplets in the final mixture remains stable, and the droplet particle size is adjusted without affecting the humidification effect and efficiency.

[0019] (3) While adjusting the filtration particle size, the atomizing particle size is also adjusted. There is a linkage relationship between the two, and no separate adjustment is required, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0039] Refer to Figures 1 - 11As shown in the figure, a portable humidifying and warming device for tracheotomy according to the present invention includes a first cup body 1, a second cup body 2 rotatably provided on the first cup body, a handle 3 fixedly provided on the first cup body, a first pipe 4 fixedly provided on the first cup body, a steam interface 5 fixedly provided on the first pipe, a first circulation mechanism 6 provided on the first cup body, an atomization mechanism 7 fixedly provided on the second cup body, a first adjustment mechanism 8 provided on the first cup body, and a second adjustment mechanism 9 provided on the first adjustment mechanism; the handle is fixedly provided on the first cup body, and is separately arranged on both sides of the first cup body from the first pipe. There is a cavity inside the first cup body, and air and atomized droplets can be mixed during the movement in the cavity; the part where the second cup body is connected to the first cup body is provided with a thread and is fixed by the thread; the first pipe is provided with an interface, which can be connected to the tracheotomy cannula of a tracheotomy patient or can be connected to a bite tube for patients without a tracheotomy cannula; the steam interface can be connected to a heating device to heat air and atomized droplets. The first circulation mechanism is used to mix air and atomized droplets and filter droplets larger than a set particle size; the atomization mechanism is used to atomize the liquid and preliminarily mix the atomized droplets with air; the first adjustment mechanism can set the maximum particle size of the droplets. Droplets larger than the set particle size will be blocked and returned to the second cup body for re-atomization. Droplets smaller than the set particle size will be mixed with air and then enter the first cup body, then enter the first pipe, and finally enter the patient's trachea; the second adjustment mechanism is used to adjust the atomization particle size. The existing atomization cup cannot adjust the atomization particle size during atomization and can only be adjusted by filtration after the atomized droplets are mixed with air. Suppose that after atomization, 30% of the liquid is small-particle size, 40% is medium-particle size, and 30% is large-particle size. These atomized droplets are mixed with air, and finally form a mixture of 50% air and 50% atomized droplets without filtration. The existing atomization cup can filter the mixture and filter out large-particle size droplets larger than the set value. Therefore, the proportion of atomized droplets in the filtered mixture is less than 50%. Since the existing atomization cup cannot adjust the particle size during atomization, if a smaller filtration value is set, the proportion of atomized droplets in the mixture will be further reduced, resulting in very little atomized droplets in the mixture inhaled by the patient, reducing the tracheal humidification effect and prolonging the humidification time, reducing the humidification efficiency. That is, the existing atomization cup will reduce the humidification effect and efficiency when adjusting the particle size. Therefore, an atomization cup that can adjust the atomization particle size is needed to synchronously adjust the filtration particle size and the atomization particle size so that the proportion of air and atomized droplets in the final mixture remains stable and the droplet particle size can be adjusted without affecting the humidification effect and efficiency;

[0040] The first circulation mechanism includes a first baffle 61 fixedly arranged on the first cup body, a second baffle 62 fixedly arranged on the first cup body, a collar 63 fixedly arranged on the first baffle and the second baffle, a plurality of first chutes 64 fixedly arranged on the collar, a sealing ring 65 fixedly arranged on the first cup body, and a filtering assembly 66 slidably arranged on the first chutes and the collar; the first baffle is an annular baffle, with a sloped surface on the side close to the first pipe and a flat surface on the side away from the first pipe; the second baffle is a semi-annular baffle, connected to the inner wall of the first cup body on the side close to the first pipe. After the gas and the atomized droplets are mixed, they pass through the gap between the second baffle and the inner wall of the first cup body, are blocked by the first baffle, and enter the first pipe along the sloped surface of the first baffle, and finally enter the patient's trachea. During the movement, the gas and the atomized droplets are continuously mixed. The second baffle can prevent the gas and the atomized droplets from entering the patient's trachea along the shortest path, and extending the path can make the gas and the atomized droplets mix more fully;

[0041] The atomization mechanism includes a support plate 71 fixedly arranged on the second cup body, a conical sleeve 72 fixedly arranged on the support plate, an air passage 73 fixedly arranged on the conical sleeve, a dispersion assembly 74 fixedly arranged on the air passage, a plurality of atomization channels 75 fixedly arranged on the conical sleeve, and a support assembly 76 fixedly arranged on the conical sleeve; the support plate is conical, and the liquid accumulates on the support plate after being poured into the second cup body; a connecting pipe is arranged below the conical sleeve, which can be connected to a portable gas cylinder for use or connected to the gas source in the hospital; the dispersion assembly is used to disperse the liquid and initially break up the liquid into droplets; when the gas enters from the bottom of the conical sleeve, due to the continuous decrease in the diameter of the air passage, the flow rate of the gas increases after flowing into the air passage. According to Bernoulli's principle, the air pressure at the top of the conical sleeve is much lower than the atmospheric pressure, and the second cup body is in communication with the external air pressure. Therefore, the liquid at the support plate is pressed into the atomization channels by the pressure difference and is broken up by the dispersion assembly at the top of the conical sleeve and is initially mixed with the air;

[0042] The filtering component includes an adjusting sleeve 661 slidably disposed on the first chute and the collar, a plurality of first sliders 662 fixedly disposed on the adjusting sleeve, a plurality of first brackets 663 fixedly disposed on the adjusting sleeve, a first through hole 664 fixedly disposed on the first bracket, a threaded sleeve 665 fixedly disposed on the adjusting sleeve, a first limiting rod 666 fixedly disposed on the adjusting sleeve, a second convex ring 667 fixedly disposed on the adjusting ring, and an atomizing rod 668 slidably disposed on the first through hole; the adjusting sleeve is a cylindrical annular sleeve that can move up and down and is used to filter droplets. By setting the position of the adjusting sleeve, the distance between the bottom of the adjusting sleeve and the top of the conical sleeve is changed. The larger the distance, the smaller the droplet diameter passing through the adjusting sleeve; the first slider cooperates with the first chute to limit the adjusting sleeve so that the adjusting sleeve can only move in the vertical direction and cannot rotate; the threaded sleeve cooperates with the first adjusting mechanism to move the adjusting collar in the vertical direction; the first limiting rod, the second convex ring cooperate with the second adjusting mechanism, and the movement of the adjusting collar drives the atomizing rod to move synchronously; after the liquid is dispersed by the dispersing component, it is initially mixed with air and ejected from the top of the conical sleeve, hitting the bottom of the atomizing rod. The closer the atomizing rod is to the conical sleeve, the greater the impact force, and the smaller the droplet diameter after atomization. The farther the atomizing rod is from the conical sleeve, the smaller the impact force, and the larger the droplet diameter after atomization. The distance between the atomizing rod and the conical sleeve is adjusted synchronously with the height of the adjusting sleeve to ensure that the proportion of air and droplets in the final mixture remains stable;

[0043] The first adjusting mechanism includes a second chute 81 fixedly disposed on the first cup body, an adjusting ring 82 rotatably disposed on the second chute, a limiting component 83 fixedly disposed on the adjusting ring and the first cup body, and a plurality of relief grooves 84 fixedly disposed on the adjusting ring; the second chute is an annular chute; the adjusting ring can rotate on the second chute, and the inner wall of the adjusting ring is provided with threads that can engage with the threaded sleeve on the adjusting sleeve. By rotating the adjusting ring, the adjusting sleeve is driven to move in the vertical direction; the limiting component is used to limit the rotation of the adjusting ring, that is, to fix the position of the adjusting sleeve; the relief groove is aligned with the first chute to provide a relief effect when inserting the adjusting sleeve;

[0044] The second adjustment mechanism includes a cover body 91, a plurality of air holes 92 fixedly arranged on the cover body, an air hole cover plate 93 rotatably arranged on the cover body, and a linkage assembly 94 fixedly arranged on the adjustment sleeve and the cover body; the cover body is connected to the adjustment ring by magnetic attraction. There is a groove on the cover body, which cooperates with the first limiting rod. When the adjustment ring rotates, it drives the adjustment sleeve to move in the vertical direction. Also, because the first limiting rod cooperates with the groove on the cover body, the cover body will not rotate with the adjustment ring. The air holes are fan-shaped air holes, and there are multiple of them. In the initial state, they are covered by the air hole cover plate. The air hole cover plate can rotate to adjust the opening and closing of the air holes. Since the air pressure at the top of the conical sleeve is relatively small, external gas will also enter the adjustment sleeve through the air holes, and then mix with the liquid droplets at the top of the conical sleeve. The more air holes are opened, the more gas flows in, that is, the proportion of air and atomized liquid droplets in the mixture is adjusted.

[0045] Specifically, the dispersion assembly includes a first dispersion plate 741 symmetrically and fixedly arranged on the air duct, a second dispersion plate 742 symmetrically arranged on the air duct, and inclined grooves 743 fixedly arranged on the first dispersion plate and the second dispersion plate; the first dispersion plate and the second dispersion plate are arranged in an alternating manner, and the tips of the inclined grooves face downward for dispersing the liquid.

[0046] Specifically, the support assembly includes a plurality of support plates 761 fixedly arranged on the conical sleeve and support blocks 762 fixedly arranged on the support plates; the support plates are arranged in a cross shape, and the outer edges of the support plates are in contact with the inner wall of the adjustment sleeve; the support blocks are used for limiting to restrict the position of the adjustment sleeve.

[0047] Specifically, the limiting assembly includes a plurality of limiting holes 831 rotatably arrayed on the first cup body, a plurality of third sliding grooves 832 fixedly arranged on the adjustment ring, limiting heads 833 slidably arranged on the third sliding grooves, and a first spring 834 with one end fixedly arranged on the limiting head and the other end fixedly arranged on the cover body; in the initial state, the limiting heads are located in the limiting holes, and the first spring is a compression spring. When the adjustment ring rotates, the limiting heads are first squeezed into the third sliding grooves, and the first spring is compressed. When rotating to the next limiting hole, the first spring pushes the limiting heads into the limiting holes.

[0048] Specifically, the linkage assembly includes a plurality of fourth chutes 941 fixedly provided on the cover plate, a first rack 942 slidably provided on the fourth chutes, a first gear 942 rotatably provided on the cover plate and meshing with the first rack, a second gear 943 rotatably provided on the cover plate and meshing with the first rack, a plurality of fifth chutes 944 fixedly provided on the cover plate, a second bracket 945 slidably provided on the fifth chutes and fixedly connected to the atomizing rod, a second rack 946 fixedly provided on the second bracket, and an engaging device 947 provided on the first limiting rod and the second convex ring; the diameter of the first gear is larger than that of the second gear; by rotating the adjusting ring, the adjusting sleeve is driven to move downward, the second gear rotates, and then the second rack is driven to move upward, the second rack drives the first gear to rotate, and the first gear drives the second rack to move downward, that is, the second bracket moves downward, and the atomizing rod approaches the conical sleeve, so that the atomizing particle size is reduced.

[0049] Specifically, the engaging device includes a third rack 9471, a sixth chute 9472 fixedly provided on the second convex ring, an unlocking block 9473 slidably provided on the sixth chute, a second spring 9474 with one end fixedly provided on the third rack and the other end fixedly provided on the first limiting rod, a third spring 9475 with one end provided on the second convex ring and the other end fixedly provided on the unlocking block, and an unlocking groove 9476 fixedly provided on the third rack; the second spring is a compression spring; the third spring is a tension spring, and the elastic force of the third spring is greater than that of the second spring; during use, first insert the adjusting sleeve, and then cover the cover body on the adjusting ring. If the engaging device is not provided, when the cover body is rotated, the third rack will be stuck with the first gear, resulting in the cover body being unable to be installed. Therefore, it is necessary to provide an engaging device to make way during the installation of the cover body; when the cover body is not installed, the right side of the unlocking block protrudes slightly, and the left inclined surface presses the unlocking groove, causing the third rack to move inward, and the second spring is compressed. At this time, when the cover body is installed, the third rack does not contact the second gear, so it will not block the installation of the cover body. When the cover body is installed, the cover body will squeeze the right side of the unlocking block, causing the unlocking block to move downward, the third spring is stretched, and the left side of the unlocking block also moves downward. The second spring returns to push the third rack to move outward and contact the second gear.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
