Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an oxygen humidification bottle for atomized inhalation. Background Technology
[0002] During clinical oxygen therapy, the oxygen delivered from oxygen cylinders is relatively dry, so oxygen humidification bottles are needed to humidify the oxygen, making it easier for patients to inhale.
[0003] Typically, patients require nebulizer therapy in addition to humidified oxygen. When a patient needs nebulizer therapy after inhaling humidified oxygen, medical staff need to disconnect the oxygen humidifier and use a different nebulizer to administer the medication. If the original oxygen humidifier is used, the medication will be diluted by the liquid inside, resulting in poor nebulization. However, frequently changing the oxygen humidifier and nebulizer makes the process very cumbersome and significantly increases the workload of medical staff. Utility Model Content
[0004] The purpose of this invention is to provide an oxygen humidification bottle for nebulized inhalation, aiming to solve the technical problem that the existing oxygen humidification bottles have poor nebulization effect, resulting in high labor intensity for medical staff.
[0005] This application provides an oxygen humidification bottle for atomized inhalation, including a bottle body and a switching device. The bottle body has an oxygen inlet channel, a humidification channel, and a cavity for containing liquid. The oxygen inlet channel and the humidification channel are arranged at intervals and are both connected to the cavity. The switching device includes a main body and a switching assembly rotatably connected to the main body. The main body includes an oxygen supply channel, an oxygen outlet channel, and an atomization channel arranged at intervals. The oxygen supply channel runs through the upper and lower surfaces of the main body. The switching assembly has a first channel and a second channel that are interconnected. The first channel runs through opposite sides of the switching assembly, and the second channel is opened at one end of the switching assembly. The atomization channel is connected to an atomizing tube. The switching device has a humidification state and an atomization state. In the humidification state, the oxygen supply channel, the first channel, and the oxygen inlet channel are connected. In the atomization state, the oxygen supply channel, the second channel, one end of the first channel, and the atomization channel are connected.
[0006] The beneficial effects of this utility model regarding a nebulizable oxygen humidification bottle are as follows: the oxygen supply channel on the main body is used to connect to an oxygen supply system; the oxygen outlet channel on the main body is used to connect to a tubing for outputting humidified oxygen; and the nebulization tube on the main body is used to connect to a tubing for outputting undiluted nebulized medication. By setting a first channel and a second channel on the switching assembly, the nebulizable oxygen humidification bottle can output either humidified oxygen or undiluted nebulized medication after the switching assembly rotates relative to the main body. In other words, this nebulizable oxygen humidification bottle has two output states: a humidification state and a nebulization state.
[0007] In use, when a patient needs to inhale humidified oxygen, the switching component is rotated to a predetermined position. At this point, the oxygen supply channel, the first channel, and the oxygen inlet channel are connected, while the switching component is closed to the nebulization channel, meaning oxygen does not enter the nebulization channel. The oxygen supply system outputs oxygen, which passes sequentially through the oxygen supply channel and the first channel, and then enters the liquid-filled chamber through the oxygen inlet channel on the bottle body. After being humidified by the liquid, the oxygen enters the main body's oxygen outlet channel through the humidification channel. In this way, the oxygen humidification bottle, which could otherwise be used for nebulized inhalation, can now provide humidified oxygen to the patient.
[0008] When a patient requires nebulization therapy, the switching component is rotated to a predetermined position. At this point, the upper end of the oxygen supply channel, the second channel, one end of the first channel, and the nebulization channel are connected, while the lower end of the oxygen supply channel is closed to the switching component. This means oxygen will not enter the lower end of the oxygen supply channel and therefore will not enter the bottle. The oxygen supply system outputs oxygen, which sequentially passes through the upper end of the oxygen supply channel, the second channel, one end of the first channel, and the nebulization channel, finally entering the nebulization tube, thus achieving the purpose of delivering undiluted nebulized medication.
[0009] It is evident that the oxygen humidification bottle for nebulized inhalation in this application can not only deliver humidified oxygen, but also deliver undiluted nebulized medication, greatly improving the nebulization effect of the oxygen humidification bottle. This eliminates the need for medical staff to frequently change oxygen humidification bottles and nebulization devices, significantly reducing the workload of medical staff.
[0010] Optionally, the main body has a rotating hole that is rotatably connected to the switching component. The oxygen supply channel and the atomization channel are connected to the rotating hole. The switching component includes a limiting member. The outer surface of the main body has a fan-shaped positioning groove that is connected to the rotating hole. The positioning groove has a first abutting surface and a second abutting surface. In the humidification state, the limiting member abuts against the first abutting surface. In the atomization state, the limiting member abuts against the second abutting surface. When the switching component rotates 90°, the switching device switches between the humidification state and the atomization state.
[0011] Optionally, the switching component also includes a first rotating shaft and a second rotating shaft that are fixedly connected. Both the first rotating shaft and the second rotating shaft are rotatably connected to the rotating hole. The first rotating shaft has a first channel and a second channel.

[0043] Please refer to Figures 1 to 6 The present invention will now describe an oxygen humidification bottle 100 for atomized inhalation according to an embodiment of the present invention.
[0044] Please refer to Figures 1 to 3This application provides an oxygen humidification bottle 100 for atomized inhalation, comprising a bottle body 10 and a switching device 20. The bottle body 10 has an oxygen inlet channel 11, a humidification channel 12, and a cavity 13 for containing liquid. The oxygen inlet channel 11 and the humidification channel 12 are arranged at intervals and are both connected to the cavity 13. The switching device 20 includes a main body 21 and a switching assembly 22 rotatably connected to the main body 21. The main body 21 includes an oxygen supply channel 211, an oxygen outlet channel 212, and an atomization channel 213 arranged at intervals. The oxygen supply channel 211 penetrates the upper and lower surfaces of the main body 21. The switching assembly 22... The component 22 has a first channel 2221 and a second channel 2222 that are interconnected. The first channel 2221 passes through the opposite sides of the switching component 22, and the second channel 2222 is opened at one end of the switching component 22. The atomizing channel 213 is connected to the atomizing tube 23. The switching device 20 has a humidification state and an atomizing state. In the humidification state, the oxygen supply channel 211, the first channel 2221 and the oxygen inlet channel 11 are connected. In the atomizing state, the oxygen supply channel 211, the second channel 2222, one end of the first channel 2221 and the atomizing channel 213 are connected.
[0045] Understandably, the oxygen supply channel 211 on the main body 21 is used to connect to the oxygen supply system, the oxygen outlet channel 212 on the main body 21 is used to connect to a trachea for outputting humidified oxygen, and the nebulizer tube 23 on the main body 21 is used to connect to a trachea for outputting undiluted nebulized medication.
[0046] In this application, by setting a first channel 2221 and a second channel 2222 on the switching component 22, the oxygen humidification bottle 100 that can be nebulized can output humidified oxygen or undiluted nebulized drugs after the switching component 22 rotates relative to the main body 21. That is, the oxygen humidification bottle 100 that can be nebulized has two output states, namely humidification state and nebulization state.
[0047] In use, when a patient needs to inhale humidified oxygen, the switching component 22 is rotated to a predetermined position. At this time, the oxygen supply channel 211, the first channel 2221, and the oxygen inlet channel 11 are connected, while the switching component 22 is closed to the nebulization channel 213, meaning that oxygen does not enter the nebulization channel 213. The oxygen supply system outputs oxygen, which passes sequentially through the oxygen supply channel 211 and the first channel 2221, and then enters the liquid-filled cavity 13 through the oxygen inlet channel 11 on the bottle body 10. After being humidified by the liquid, the oxygen enters the oxygen outlet channel 212 of the main body 21 through the humidification channel 12 of the bottle body 10. In this way, the oxygen humidification bottle 100, which can be used for nebulized inhalation, can provide humidified oxygen to the patient.
[0048] When a patient needs nebulization therapy, the switching component 22 is rotated to another predetermined position. At this time, the upper end of the oxygen supply channel 211, the second channel 2222, one end of the first channel 2221, and the nebulization channel 213 are connected, while the lower end of the oxygen supply channel 211 is closed to the switching component 22. That is, oxygen will not enter the lower end of the oxygen supply channel 211 and therefore will not enter the bottle 10. The oxygen supply system outputs oxygen, which passes sequentially through the upper end of the oxygen supply channel 211, the second channel 2222, one end of the first channel 2221, and the nebulization channel 213, and finally enters the nebulization tube 23, thereby achieving the purpose of outputting undiluted nebulized medication.
[0049] It is evident that the oxygen humidification bottle 100 for nebulization in this application can not only deliver humidified oxygen, but also deliver undiluted nebulized medication, greatly improving the nebulization effect of the oxygen humidification bottle. This eliminates the need for medical staff to frequently change the oxygen humidification bottle and nebulization device, significantly reducing the workload of medical staff.
[0050] In another embodiment of this application, please refer to Figure 5 The main body 21 has a rotating hole 214 that is rotatably connected to the switching component 22. The oxygen supply channel 211 and the atomization channel 213 are connected to the rotating hole 214. The switching component 22 includes a limiting member 221. The outer surface of the main body 21 has a fan-shaped positioning groove 215 that is connected to the rotating hole 214. The positioning groove 215 has a first abutting surface 2151 and a second abutting surface 2152. In the humidification state, the limiting member 221 abuts against the first abutting surface 2151. In the atomization state, the limiting member 221 abuts against the second abutting surface 2152. When the switching component 22 rotates 90°, the switching device 20 switches between the humidification state and the atomization state.
[0051] Specifically, the rotating hole 214 penetrates both the front and rear surfaces of the main body 21 in the front-rear direction, and the positioning groove 215 is formed on the front surface of the main body 21, with a diameter larger than that of the rotating hole 214. The outlet of the oxygen outlet channel 212 is located on the left surface of the main body 21, and the outlet of the atomizing channel 213 is located on the right surface of the main body 21, i.e., the oxygen outlet channel 212 and the atomizing channel 213 are arranged opposite to each other. The first channel 2221 and the second channel 2222 are generally in a "T" shape, and the switching component 22 rotates around the front-rear direction. This arrangement simplifies the overall structure of the switching device 20.
[0052] When a patient needs to inhale humidified oxygen, the switching assembly 22 is rotated until the limiting member 221 abuts against the first contact surface 2151. At this time, the oxygen humidification bottle 100, which is designed for nebulization, is in a humidified state. When a patient needs nebulization therapy, the switching assembly 22 is rotated 90°. At this time, the limiting member 221 abuts against the second contact surface 2152, and the oxygen humidification bottle 100, which is designed for nebulization, is in a nebulization state.
[0053] The positioning groove 215 allows medical staff to adjust the output state of the oxygen humidification bottle 100 without visual adjustment. They can feel the force generated by the contact between the limiting member 221 and the positioning groove 215, which helps improve the adjustment efficiency of the oxygen humidification bottle 100.
[0054] In another embodiment of this application, please refer to Figures 4 to 6 The switching component 22 also includes a first rotating shaft 222 and a second rotating shaft 223 that are fixedly connected. Both the first rotating shaft 222 and the second rotating shaft 223 are rotatably connected to the rotating hole 214. The first rotating shaft 222 has a first channel 2221 and a second channel 2222. The first channel 2221 passes through the opposite sides of the first rotating shaft 222. The second rotating shaft 223 is connected to the limiting member 221.
[0055] Specifically, both the first rotating shaft 222 and the second rotating shaft 223 rotate in the front-rear direction, with the first rotating shaft 222 inserted into the main body 21 from the front and the second rotating shaft 223 inserted into the main body 21 from the rear. By constructing the switching component 22 as a split structure, on the one hand, the manufacturing difficulty of the switching component 22 can be reduced; on the other hand, it allows medical personnel to adjust the output state of the oxygen humidification bottle 100 for nebulization not only by rotating the first rotating shaft 222, but also by rotating the second rotating shaft 223. That is, medical personnel can adjust the output state of the oxygen humidification bottle 100 for nebulization in both front and rear directions, greatly improving flexibility.
[0056] In another embodiment of this application, please refer to Figure 5 and Figure 6 The outer circular surface of the first rotating shaft 222 is provided with a first limiting ring 2223, and the outer surface of the main body 21 is provided with a first limiting groove 216 that abuts against the first limiting ring 2223. The outer circular surface of the second rotating shaft 223 is provided with a second limiting ring 2231, and the outer surface of the main body 21 is provided with a second limiting groove 217 that abuts against the second limiting ring 2231. The first limiting groove 216 and the second limiting groove 217 are respectively provided on two opposite outer surfaces of the main body 21.
[0057] Specifically, the diameter of the first limiting ring 2223 is larger than the diameter of the first rotating shaft 222, and the diameter of the second limiting ring 2231 is larger than the diameter of the second rotating shaft 223. A first limiting groove 216 is formed on the rear surface of the main body 21, and both the second limiting groove 217 and the positioning groove 215 are formed on the front surface of the main body 21. The diameters of both the first limiting groove 216 and the second limiting groove 217 are larger than the diameter of the rotating hole 214, and the diameter of the second limiting groove 217 is smaller than the diameter of the positioning groove 215. The first limiting groove 216 communicates with the rotating hole 214, and the second limiting groove 217 communicates with both the rotating hole 214 and the positioning groove 215. When the first rotating shaft 222 rotates, the first limiting ring 2223 rotates within the first limiting groove 216. When the second rotating shaft 223 rotates, the second limiting ring 2231 rotates within the second limiting groove 217.
[0058] The arrangement of the first limiting ring 2223, the first limiting groove 216, the second limiting ring 2231, and the second limiting groove 217 ensures that after the first rotating shaft 222 and the second rotating shaft 223 are fixedly connected, the first rotating shaft 222 and the second rotating shaft 223 cannot move in the forward and backward direction. This ensures that when the switching device 20 is in the humidification state, the oxygen supply channel 211 and the first channel 2221 can be connected, and that when the switching device 20 is in the atomization state, the upper end of the oxygen supply channel 211, the second channel 2222, and the first channel 2221 can be connected. Specifically, the first limiting ring 2223 and the first limiting groove 216 jointly restrict the forward movement of the first rotating shaft 222, while the second limiting ring 2231 and the second limiting groove 217 jointly restrict the backward movement of the second rotating shaft 223.
[0059] During assembly, the first rotating shaft 222 is inserted into the main body 21 from the rear until the first limiting ring 2223 abuts against the first limiting groove 216. The second rotating shaft 223 is then inserted into the main body 21 from the front until the second limiting ring 2231 abuts against the second limiting groove 217. Finally, the first rotating shaft 222 and the second rotating shaft 223 are fixedly connected together. It is evident that the first limiting ring 2223, the first limiting groove 216, the second limiting ring 2231, and the second limiting groove 217 not only serve a restraining function but also a positioning function.
[0060] In another embodiment of this application, please refer to Figure 5 The outer circular surface of the first rotating shaft 222 is provided with at least two grooves 2224 for installing the sealing strip, wherein at least one groove 2224 is located on the side of the first channel 2221 away from the first limiting ring 2223, and at least one groove 2224 is located on the side of the first channel 2221 close to the first limiting ring 2223.
[0061] Specifically, at least one groove 2224 is provided on both the front and rear sides of the first channel 2221. Exemplarily, in this embodiment, a groove 2224 is provided on both the front and rear sides of the first channel 2221. The grooves 2224 extend circumferentially along the first rotating shaft 222 and are connected end-to-end to form a closed-loop structure. After a sealing strip is installed within the groove 2224, the sealing strip slightly protrudes from the groove 2224, for example, by 0.1–0.2 mm. This allows the sealing strip to provide a sealing function while enabling medical personnel to smoothly rotate the first rotating shaft 222 or the second rotating shaft 223.
[0062] In another embodiment of this application, the first rotating shaft 222 and the second rotating shaft 223 are snap-fitted together. Compared to a threaded connection between the first rotating shaft 222 and the second rotating shaft 223, this snap-fit method reduces the possibility of loosening when medical personnel rotate the first rotating shaft 222 or the second rotating shaft 223. If they become loose, the relative positions of the oxygen supply channel 211 and the first channel 2221 may shift, affecting the output effect. The snap-fitting of the first rotating shaft 222 and the second rotating shaft 223 helps to improve the connection stability between them.
[0063] In another embodiment of this application, please refer to Figure 6 A slot 2225 is provided on the end face of the first rotating shaft 222 near the second rotating shaft 223. A snap-fit groove 2226 is provided on the wall of the slot 2225. A snap-fit block 2232 is provided on the outer circular surface of the end of the second rotating shaft 223 near the first rotating shaft 222. A deformation groove 2233 is provided on the end face of the second rotating shaft 223 near the first rotating shaft 222. The deformation groove 2233 passes through the opposite sides of the second rotating shaft 223 along the radial direction of the first rotating shaft 222. The deformation groove 2233 extends along the axial direction of the second rotating shaft 223 to the side of the snap-fit block 2232 near the second limiting ring 2231.
[0064] Specifically, slot 2225 is formed on the front end face of the first rotating shaft 222, and locking groove 2226 penetrates one side of the first rotating shaft 222 radially. Locking block 2232 is located at the rear end of the second rotating shaft 223, and deformation groove 2233 is formed on the rear end face of the second rotating shaft 223. The locking block 2232 and locking groove 2226 enable the locking of the first rotating shaft 222 and the second rotating shaft 223. The deformation groove 2233 allows the locking block 2232 to deform when the first rotating shaft 222 is inserted into the second rotating shaft 223, so that it can smoothly enter the slot 2225.
[0065] In another embodiment of this application, a guide ramp is provided at the end of the card block 2232 away from the second limiting ring 2231. This arrangement allows the card block 2232 to be inserted into the slot 2225.
[0066] In another embodiment of this application, please refer to Figure 5 and Figure 6 A first frustum 2227 is provided at the end of the first rotating shaft 222 away from the main body 21, and the diameter of the first frustum 2227 is larger than the diameter of the first rotating shaft 222. This arrangement allows medical staff to easily rotate the first rotating shaft 222.
[0067] Furthermore, the outer circular surface of the first frustum 2227 is provided with a plurality of first anti-slip stripes, which are arranged at intervals along the circumference of the first frustum 2227 and extend in the front-back direction.
[0068] In another embodiment of this application, please refer to Figure 5 and Figure 6 A second frustum 2234 is provided at the end of the second rotating shaft 223 away from the main body 21, and the diameter of the second frustum 2234 is larger than the diameter of the second rotating shaft 223. This arrangement allows medical staff to easily rotate the second rotating shaft 223.
[0069] Furthermore, the outer circular surface of the second frustum 2234 is provided with a plurality of second anti-slip stripes, which are arranged at intervals along the circumference of the second frustum 2234 and extend in the front-back direction.
[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
