Description

Technical Field

[0001] The invention relates to the technical field of biomedicine, in particular to an atomizing device for a tracheotomy cannula. Background Art

[0002] An intubation nebulizer is a device that converts liquid medication into fine droplets and delivers the drug droplets directly into the patient's lower respiratory tract through a tracheotomy or endotracheal tube. This device is commonly used in hospitals and homes to provide drug therapy to patients.

[0003] In the existing nebulizer device for tracheotomy intubation, a liquid extraction hose is usually used to extract the medicine from the medicine cup to the nebulizer. However, in the process of changing the medicine, the liquid extraction hose is easy to move away from the liquid pump and contact the surface of the medicine cup. This contact may cause bacteria or other microorganisms on the surface of the medicine cup to be transferred to the liquid extraction hose, which is then sucked into the nebulizer by the liquid pump and enters the patient's trachea through the nebulizer tube. Since the liquid extraction hose may contact the surface of the medicine cup, the purity of the medicine is difficult to ensure. Once the medicine is contaminated, its therapeutic effect will be greatly reduced and may even have adverse effects on the patient. In addition, when changing the medicine, medical staff need to operate carefully to avoid contact between the liquid extraction hose and the medicine cup, which not only increases the complexity of the operation, but also due to the uncertainty of human operation, there is still a certain risk of cross-contamination. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an atomizing device for a tracheotomy tube, comprising a casing. The present invention can reel a liquid extraction hose connected to an input end of a liquid pump into the casing through a designed motor and a rotating rod, so as to prevent the liquid extraction hose from being away from the liquid pump and entering one end of a medicine cup. When the medicine in the medicine cup is replaced, the surface of the liquid extraction hose contacts the surface of the medicine cup, resulting in bacteria and the like existing on the surface of the medicine cup being transmitted to the atomizer by the liquid pump and then entering the patient's trachea through the atomization tube, thereby reducing the risk of bacteria and other pathogens being transmitted to the atomizer through the liquid extraction hose to a certain extent, thereby reducing the nosocomial infection that may occur to the patient during the atomization treatment process. In addition, since the liquid extraction hose will not contact the surface of the medicine cup when replacing the medicine, the present invention ensures the purity of the medicine, avoids contamination of the medicine, ensures the stability and reliability of the atomization treatment effect, and simplifies the operation process of medical staff when replacing the medicine, reduces the operation steps, and reduces the risk of accidents caused by improper operation.

[0044] There are two mounting blocks 203 , and the mounting blocks 203 are distributed at the front and rear sides of the middle of the protective cover 201 . A hole is provided in the middle of the mounting block 203 , and the diameter of the hole matches the diameter of the longitudinal section of the hollow cylinder 202 .

[0045] In this embodiment, the hollow tube 202 can be fixed in the arc-shaped protective cover 201, so that the clamping plate 206 at the top inner side of the hollow tube 202 clamps the mist delivery tube 2, thereby keeping the mist delivery tube 2 stable.

[0048] In an optional embodiment: the method of fixing the long strap 3 and the short strap 302 on the patient's neck is: the long strap 3 drives the Velcro 301 to bypass the patient's neck, and adheres and fixes to the Velcro 303 at the top of the short strap 302 on the front side of the patient's neck.

[0049] In this embodiment: the adhesion position between the Velcro tape 301 and the Velcro mother tape 303 can be located on one side of the patient's neck, which can effectively prevent the Velcro tape 301 and the Velcro mother tape 303 from adhering to the patient's neck directly below the patient's neck, thereby avoiding the patient from feeling uncomfortable due to long-term pillow pressure on the Velcro tape 301 and the Velcro mother tape 303.

[0050] In an optional embodiment: the material of the long strap 3 and the short strap 302 is the same organic cotton woven layer, the longitudinal section shape of the long strap 3 and the short strap 302 is concave, and the bamboo fiber layer 304 and the polylactic acid woven layer 305 are both fixed on the inner side of the long strap 3 and the short strap 302, the long strap 3 and the short strap 302 are made of 100% organic cotton, and the thickness of the long strap 3 and the short strap 302 is uniformly 1.5mm, the bamboo fiber layer 304 is made of 60% bamboo fiber and 40% cotton fiber, and the thickness of the bamboo fiber layer 304 is uniformly 2.5mm, the polylactic acid woven layer 305 is made of polylactic acid, and the thickness of the polylactic acid woven layer 305 is 4mm, and the bamboo fiber layer 304 and the polylactic acid woven layer 305 on the inner side of the long strap 3 and the short strap 302 are cross-stitched and connected by sutures.

[0051] In this embodiment: the materials used for the long strap 3 and the short strap 302 are both organic cotton layers, which are in contact with the skin of the patient's neck when the patient lies flat. The middle layer is the bamboo fiber layer 304, which can provide additional support and fixation while maintaining good moisture absorption and perspiration performance, helping to keep the skin dry. The polylactic acid layer 305 is the outermost layer, which can provide stronger fixation and structural stability. The stacking of the three layers can provide comfort and breathability for the patient's skin.

[0052] Working principle: when in use, place the well-proportioned liquid medicine on the right side of the front end of the casing 1, then insert the mist delivery tube 2 extending from the casing 1 through the middle of the protective cover 201, then insert the top of the mist delivery tube 2 passing through the protective cover 201 into the patient's trachea, after the top of the mist delivery tube 2 reaches the set position, pull the protective cover 201 on the outside of the mist delivery tube 2, push the protective cover 201 to the patient's neck, and when the mist delivery tube 2 stops moving, the protective cover 201 passed by the mist delivery tube 2 moves until the protective cover 201 contacts the patient's neck, then let the long strap 3 drive the Velcro 301 to bypass the patient's neck, and adhere to the Velcro mother patch 303 at the top of the short strap 302 on the front side of the patient's neck, at this time, the protective cover 201 is installed, turn on the motor 105 inside the casing 1, and the motor 105 drives the output shaft 108 at the output end to rotate, and The rotating rod 107 at the front end of the output shaft 108 rotates with the output shaft 108. At this time, the mist delivery tube 2 wrapped around the rotating surface extends downward and extends into the medicine cup 101 placed on the right side of the front end of the interface. The fixed wheel 106 at the front end of the motor 105 but fixed in the housing 1 is also wrapped around the liquid extraction hose 103. However, the liquid extraction hose 103 passes through the through hole 109 at the front end of the fixed wheel 106 and is wrapped around the surface of the rotating rod 107, so as to prevent the mist delivery tube 2 near the input end of the liquid pump 102 from being pulled by the rotating rod 107. After the liquid extraction hose 103 enters the bottom of the medicine cup 101, the motor 105 is turned off, and the liquid pump 102 and the nebulizer 104 inside the housing 1 are turned on. The liquid pump 102 extracts the medicine in the medicine cup 101 through the liquid extraction hose 103 and transfers it to the nebulizer 104. After the nebulizer 104 atomizes the medicine, it is continuously input into the patient's trachea through the mist delivery tube 2.

[0053] At this time, the patient receiving nebulizer treatment lies flat on the bed, and the neck skin bound by the long strap 3 and the short strap 302 is in contact with the long strap 3. The materials used for the long strap 3 and the short strap 302 are both organic cotton woven layers, which are in contact with the skin of the patient's neck after lying down. The middle layer is the bamboo fiber layer 304, which can provide additional support and fixation while maintaining good moisture absorption and perspiration performance, which helps to keep the skin dry. The polylactic acid woven layer 305 is the outermost layer, which can provide stronger fixation and structural stability. The stacking of the three woven layers can provide comfort and breathability for the patient's skin, and the Velcro 301 at the top of the long strap 3 and the Velcro mother patch 303 at the top of the short strap 302 are adhered and fixed to each other, so that the adhesion position between the Velcro 301 and the Velcro mother patch 303 can be on one side of the patient's neck, which can effectively prevent the Velcro 30 The position where the magic tape 301 and the magic tape 303 are adhered is just below the patient's neck, so as to avoid the patient's discomfort caused by long-term pillow pressure on the magic tape 301 and the magic tape 303. At the same time, the mist delivery tube 2 that passes through the protective cover 201 is clamped by two sets of clamping plates 206 in the middle of the inner side of the protective cover 201. The clamping plate 206 is limited by the compression spring 204 at the top end of the outer side of the sliding rod 205. The compression spring 204 is in the hollow cylinder 202, so that the clamping plate 206 can continue to apply pressure to the mist delivery tube 2, but the spring force of the compression spring 204 is always 2N less than the anti-deformation force of the mist delivery tube 2. This can effectively avoid the situation where the anti-deformation force of the mist delivery tube 2 is smaller than the spring force of the compression spring 204 when the compression spring 204 drives the clamping plate 206 to fix the outer side of the mist delivery tube 2, resulting in obvious deformation of the mist delivery tube 2, thereby improving the stability of the mist delivery tube 2 during use to a certain extent.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
