Description

Technical Field

[0001] The invention relates to the field of clinical medical nursing devices, and in particular to an oral airway humidification device for clinical nursing. Background Art

[0002] Oral airway humidification is a form of care for the trachea. Airway humidification can help the respiratory tract maintain normal humidity and ensure the normal physiological function of the respiratory mucosa. It disperses water or solution into extremely fine particles through a humidifier or other device to maintain airway humidity. Reasonable help in airway humidification can greatly help dilute sputum, promote sputum discharge, maintain airway patency, and thus reduce the probability of lung infection. Sometimes patients undergo surgery, and after tracheotomy, the upper respiratory tract completely loses the heating, humidification, and filtering functions of the gas, and the defense The function is weakened. If the artificial airway is not humidified enough during nursing work, sputum crust will form on the artificial airway or upper respiratory tract. Once the sputum crust is formed, it can block the bronchi, increase airway resistance, cause peripheral dyspnea, suffocation, and tracheotomy is prone to infection. If the tube is placed for too long, it can easily cause ischemia and necrosis of the tracheal mucosa, which will cause certain damage to lung function or cause airway obstruction. The lung infection rate increases with the decrease in airway humidification. Therefore, oral airway humidification is very important, and thus an oral airway humidification device for clinical nursing has been introduced.

[0003] Most of the oral airway humidification devices currently available on the market only use wet gauze to directly cover the patient's lips to enhance the humidity of the oral cavity and airway, or insert a breathing tube from the patient's mouth into the patient's mouth or airway, and spray the vaporized liquid from the humidifier into the patient's mouth or airway through the breathing tube. The dryness and wetness of the gauze are difficult to control. If the gauze is too wet, it is easy to wet the cheeks and collar, and even cause aspiration, increasing the probability of aspiration pneumonia. If it is too dry, it evaporates too quickly, and the gauze block usually needs to be replaced in about half an hour. After the gauze block is dry, it is easy to fall off and has no humidification effect. If the patient has a fever, the replacement is more frequent, the nurse's workload is heavy, and it is also impossible to continuously provide humidity to the patient's mouth and airway. The patient may be in an unconscious coma after surgery, with a tightly closed mouth. The breathing tube with a single structure fixed is not easy to insert into the patient's mouth, and cannot be adjusted according to the size of the patient's mouth opening. There may be a risk of accidental detachment and falling. The single valve cannot accurately control the size of the humidification flow, and it is not convenient to make corresponding adjustments according to the conditions of different patients. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an oral airway humidification device for clinical care, which can continuously provide humidity to the patient's oral cavity and airway.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1-Figure 16 , an embodiment provided by the present invention: an oral airway humidification device for clinical care, comprising a bottle body 1 and a mask assembly 4, wherein the mask assembly 4 is arranged on one side of the bottle body 1;

[0039] The mask assembly 4 includes a transparent silicone mask 41 and an expanded humidification component 42 rotatably connected to the middle part of the lower section of the transparent silicone mask 41;

[0040] The expanded humidification component 42 includes a hollow rotating rod 421 rotatably connected to the middle part of the lower section of the transparent silicone mask 41, a twist block 4210 fixedly connected to one end of the hollow rotating rod 421, and an atomizing nozzle 422 fixedly connected to one end of the hollow rotating rod 421 away from the twist block 4210, the end of the atomizing nozzle 422 away from the hollow rotating rod 421 is fixedly connected to a shell 423, the middle part of the end of the shell 423 away from the atomizing nozzle 422 is rotatably connected to a threaded rod 424, the end of the threaded rod 424 away from the shell 423 is rotatably connected to a silicone threaded cone 428, and the side of the silicone threaded cone 428 close to the threaded rod 424 is fixedly connected to an expansion plate 427;

[0041] The top of the bottle body 1 is fixedly connected with a switch valve mechanism 2, the switch valve mechanism 2 is connected with the mask assembly 4 through a connecting conveying assembly 3, and the outside of the connecting conveying assembly 3 is slidably connected with a conveying volume adjustment assembly 5;

[0042] The delivery volume regulating component 5 comprises a bottom block 51 slidably connected to the outside of the delivery tube 32, a nut 55 slidably connected to the outside of the delivery tube 32, and a threaded shell 54 fixedly connected to the bottom block 51 near the nut 55. A through hole 1 52 is provided in the middle of the bottom block 51, and a through hole 2 56 is provided in the middle of the nut 55. A plurality of clamps 53 are evenly fixedly connected to the edge of the through hole 1 52 near the nut 55. The threaded shell 54 is threadedly connected to one end of the nut 55. Before using the device, place the device next to the patient who needs the device, put the mask assembly 4 on the patient's head through the elastic band 44, and make the transparent silicone mask 41 located in front of the patient's face, align the silicone threaded cone 428 in the expanded humidification component 42 with the patient's mouth, and gently insert the small head of the silicone threaded cone 428 between the patient's upper and lower teeth, and twist the block 4 210 twists the hollow rotating rod 421, and then drives the silicone threaded cone 428 and the expansion plate 427 to rotate through the atomizing nozzle 422, the shell 423 and the threaded rod 424. During the rotation process, the patient's upper and lower teeth are close to the outer wall of the silicone threaded cone 428, and the silicone threaded cone 428 is gradually rotated into the patient's mouth through the threads of the outer wall. After the silicone threaded cone 428 lightly pries open the patient's teeth, it can easily slide into the patient's mouth because the surface of the expansion plate 427 is inclined and smooth. As a result, when the patient is in an unconscious coma stage and the teeth are tightly closed, the silicone threaded cone 428 and the expansion plate 427 can also pry open the patient's teeth without hurting the patient, which is convenient for the subsequent exploration of the device and the humidification of the oral airway. Because the material of the silicone threaded cone 428 and the expansion plate 427 are both hard silicone, they have a certain hardness, but will not hurt the patient's mouth and airway.

[0043] The middle periphery of the hollow rotating rod 421 is fixedly connected to the limiting block 4211, and a plurality of through holes 429 are evenly opened on the outer side of the hollow rotating rod 421 near the end of the torsion block 4210. The transparent silicone mask 41 is arranged between the torsion block 4210 and the limiting block 4211. This structure can prevent the hollow rotating rod 421 from accidentally displacing during the rotation process and injuring the patient. The side of the transparent silicone mask 41 near the limiting block 4211 is concave, and a plurality of through holes 429 are all arranged inside the transparent silicone mask 41. The transparent silicone mask 41 is convenient for medical staff to observe the patient's condition. A plurality of atomizing spray holes are evenly opened on the periphery of the atomizing nozzle 422. The inside of the outer shell 423 is fixedly connected to the motor 4212. The output end of the motor 4212 is fixedly connected to the end of the threaded rod 424 near the outer shell 423. The outer wall of the threaded rod 424 is threadedly connected to a threaded sleeve 425. The outer wall of the threaded sleeve 425 is evenly rotatably connected to the plurality of A connecting rod 426, one end of the connecting rod 426 away from the threaded sleeve 425 is rotatably connected to the inner wall of the expansion plate 427. When the patient's mouth shape changes unconsciously or the oral cavity sizes of different patients are different, the motor 4212 inside the shell 423 is started to drive the threaded rod 424 to rotate. Because the silicone thread cone 428 and the expansion plate 427 are held by the patient, they will not rotate with the rotation of the threaded rod 424. Because the outer wall of the threaded sleeve 425 is evenly rotated and connected with multiple connecting rods 426, one end of the connecting rod 426 away from the threaded sleeve 425 is rotatably connected to the inner wall of the expansion plate 427, so that the threaded sleeve 425 can move along the threaded rod 424 with the rotation of the threaded rod 424, and then the expansion plate 427 can be retracted or stretched through the connecting rod 426, so that the size of the expansion plate 427 can be adjusted, and thus it can be adjusted according to the size of the patient's mouth, making the device more convenient and firm when used;

[0044] The connecting and conveying component 3 includes a screwing bolt sleeve 31 threadedly connected to the lower side of the end of the switch valve mechanism 2 away from the bottle body 1, a conveying pipe 32 fixedly connected to the end of the screwing bolt sleeve 31 away from the switch valve mechanism 2, and a shunt connector 33 fixedly connected to the end of the conveying pipe 32 away from the screwing bolt sleeve 31. The end of the shunt connector 33 away from the conveying pipe 32 is fixedly connected to two branch pipes 34, and the ends of the two branch pipes 34 away from the shunt connector 33 are fixedly connected to a fixed twist tube 35. Two connecting ports 43 are provided on one side of the transparent silicone mask 41 close to the twist block 4210. The two fixed twist tubes 35 are respectively arranged in the middle of the two connecting ports 43. The fixed twist tube 35 is connected to the through port 429 inside the transparent silicone mask 41, and the silicone threaded cone 428 and the expansion plate 427 are inserted into the patient's oral cavity and the airway. After the passage is formed, the switch valve mechanism 2 can be unscrewed, so that the humidifying liquid in the bottle body 1 is vaporized and flows out, and after the bolt sleeve 31, the delivery pipe 32 and the diversion connector 33 are twisted, the diversion is passed through the diversion connector 33, and then enters the transparent silicone mask 41 through the fixed twist tube 35 and the connection port 43, and then flows into the hollow rotating rod 421 through the opening 429, and then is sprayed out through the atomizing nozzle 422, so as to humidify the patient's oral cavity and airway. The transparent silicone mask 41 is fixedly connected with an elastic band 44 in the middle of one side away from the twist block 4210, and multiple cracks are evenly opened on the outside of the expansion plate 427. The rotation connection points of multiple connecting rods 426 and the inner wall of the expansion plate 427 are not in the same position as the cracks on the outside of the expansion plate 427, and the outside of the connecting delivery component 3 is slidably connected with a delivery volume adjustment component 5;

[0045] A plurality of clamps 53 are arranged in the middle of the threaded shell 54, the delivery pipe 32 is arranged in the middle of the through hole 1 52, the threaded shell 54 and the through hole 2 56, the delivery pipe 32 is arranged between the plurality of clamps 53, the inner wall of the threaded shell 54 is provided with an inner cavity 57, the ends of the plurality of clamps 53 away from the bottom block 51 are arranged inside the inner cavity 57, the middle part of the end of the nut 55 close to the threaded shell 54 is provided with an arc groove 58, the ends of the plurality of clamps 53 away from the bottom block 51 are arranged in the middle of the arc groove 58, when the size of the humidification flow needs to be adjusted, it can be roughly adjusted by the switch valve mechanism 2 first, and then the nut 5 is turned to adjust the flow rate. 5, so that the nut 55 is rotated on the threaded shell 54 toward the bottom block 51, and the nut 55 is screwed into the threaded shell 54, squeezing the end of the clamp 53 away from the bottom block 51, so that the end of the clamp 53 away from the bottom block 51 is squeezed by the nut 55, so that the ends of the clamps 53 away from the bottom block 51 gather toward the middle along the direction of the arc groove 58, so that the multiple clamps 53 gradually clamp the delivery tube 32, so that the internal space of the delivery tube 32 becomes narrower, the flow rate is reduced, and then the adjustment is completed, thereby achieving multiple flow adjustments, which can better and more accurately control the size of the humidification flow, and facilitate corresponding adjustments according to different patient conditions.

[0046] Working principle: Before using the device, place the device next to the patient who needs the device, put the mask assembly 4 on the patient's head through the elastic band 44, and make the transparent silicone mask 41 be located in front of the patient's face, align the silicone threaded cone 428 in the expanded humidification component 42 with the patient's mouth, and gently insert the small head of the silicone threaded cone 428 between the patient's upper and lower teeth, twist the hollow rotating rod 421 through the twist block 4210, and then drive the silicone threaded cone 428 and the expansion plate 427 to rotate through the atomizing nozzle 422, the shell 423 and the threaded rod 424. During the rotation, the patient's upper and lower teeth are close to the outer wall of the silicone threaded cone 428, and the silicone threaded cone 428 is gradually rotated into the patient's mouth through the thread of the outer wall, and the silicone threaded cone 428 gently pries open the patient's After the patient's teeth are opened, the expansion plate 427 can be easily slid into the patient's mouth because of its inclined and smooth surface. As a result, when the patient is in an unconscious coma and the teeth are tightly closed, the silicone threaded cone 428 and the expansion plate 427 can also pry open the patient's teeth without hurting the patient, so as to facilitate the subsequent insertion of the device and the humidification of the oral airway. Since the silicone threaded cone 428 and the expansion plate 427 are made of hard silicone, they have a certain hardness, but will not hurt the patient's mouth and airway. After the silicone threaded cone 428 and the expansion plate 427 are inserted into the patient's mouth and airway, the switch valve mechanism 2 can be unscrewed to make the humidification liquid in the bottle body 1 vaporize and flow out. By screwing the bolt sleeve 31, the delivery tube 32 and the shunt connector 33, the humidification liquid passes through the shunt connector 33. The liquid is then diverted and flows into the transparent silicone mask 41 through the fixed twist tube 35 and the connecting port 43, and then flows into the hollow rotating rod 421 through the opening 429, and then is atomized and sprayed out through the atomizing nozzle 422, thereby humidifying the patient's oral cavity and airway. When the patient's mouth shape changes unconsciously or the oral cavity sizes of different patients are different, the motor 4212 inside the shell 423 is started to drive the threaded rod 424 to rotate. Because the silicone thread cone 428 and the expansion plate 427 are held by the patient, they will not rotate with the rotation of the threaded rod 424. Because the outer wall of the threaded sleeve 425 rotates evenly and is connected to multiple connecting rods 426, the end of the connecting rod 426 away from the threaded sleeve 425 is rotatably connected to the inner wall of the expansion plate 427, so that the threaded sleeve 425 can rotate with the rotation of the threaded sleeve 424. The threaded rod 424 rotates and moves along the threaded rod 424, and then the expansion plate 427 can be retracted or stretched through the connecting rod 426, so that the size of the expansion plate 427 can be adjusted, and thus it can be adjusted according to the size of the patient's mouth opening, making the device more convenient and firm to use. When the size of the humidification flow rate needs to be adjusted, it can be roughly adjusted through the switch valve mechanism 2 first, and then the nut 55 is twisted to make the nut 55 rotate on the threaded shell 54 toward the bottom block 51. The nut 55 is screwed into the threaded shell 54, squeezing the end of the splint 53 away from the bottom block 51, so that the end of the splint 53 away from the bottom block 51 is squeezed by the nut 55, so that the ends of the multiple splints 53 away from the bottom block 51 gather toward the middle along the direction of the arc groove 58.The multiple clamps 53 gradually clamp the delivery tube 32, making the internal space of the delivery tube 32 narrower and the flow rate reduced, thereby completing the adjustment, thereby achieving multiple flow adjustments, which can better and more accurately control the size of the humidification flow rate and facilitate corresponding adjustments according to different patient conditions.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
