Description

Technical Field

[0001] The present invention relates to the technical field of oxygen inhalers, and particularly relates to an oxygen inhaler with a breathing assistance function. Background Art

[0002] An oxygen inhaler is a medical device used for oxygen flow measurement. It is used to control and regulate the oxygen flow released from an oxygen compression bottle to assist patients in safely inhaling oxygen. In the prior art, after the pressure of the oxygen compression bottle is relieved by a pressure valve in the oxygen inhaler, a humidifying bottle is used to humidify the dry normal-pressure oxygen to prevent the dry oxygen from irritating the respiratory tract. When the water level in the humidifying bottle is lower than the appropriate level, the humidifying effect is weakened because the water in the humidifier is not sufficient to fully contact the passing oxygen. When the water level in the humidifying bottle is higher than the appropriate level, the sterile water in the humidifying bottle may splash into the nasal tube (i.e., over-humidification), which will cause moisture to be entrained in the oxygen and may cause choking or discomfort in the throat when the patient inhales. In the existing device, the oxygen inlet position in the humidifying bottle is fixed. As the amount of oxygen humidification gradually increases, the sterile water in the humidifying bottle will gradually decrease. Therefore, the distance between the oxygen injection point and the water surface of the sterile water will gradually decrease over time, thus affecting the humidifying effect of the sterile water on oxygen and even affecting the patient's respiratory tract. Summary of the Invention

Detailed implementation manners

[0017] The following further illustrates the technical solution with specific embodiments. It should be noted that: The words indicating directions such as up, down, left, and right in this text are only for the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this text itself, such as the first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application, the term "connection", unless otherwise specified, includes both direct and indirect connections.

[0018] Research shows that when the water level in the humidifying bottle is lower than the appropriate level, the humidity in the humidifying bottle is not sufficient to fully contact the passing oxygen, thereby weakening the humidifying effect of oxygen. When the water level in the humidifying bottle is higher than the appropriate level, the sterile water in the humidifying bottle will splash into the nasal tube (i.e., over-humidification), which will cause moisture to be entrained in the oxygen. When the patient inhales, it may cause coughing or throat discomfort. In the existing device, the oxygen inlet position in the humidifying bottle is fixed. As the amount of oxygen humidification gradually increases, the sterile water in the humidifying bottle will gradually decrease. Therefore, the distance between the oxygen injection point and the sterile water surface will gradually decrease over time, thereby affecting the humidifying effect of the sterile water on oxygen and even affecting the patient's respiratory tract.

The sealing cover 2 is fixedly connected with an air inlet pipe 3. The air inlet pipe 3 communicates with the closed space formed by the water storage shell 1 and the sealing cover 2. A pressure reducing member 4 is arranged on the right side of the air inlet pipe 3. The pressure reducing member 4 consists of a pressure gauge, a pressure reducing valve and a safety valve, and all are of the prior art, so no more details will be described here. A sliding pipe 5 is slidably connected to the outer side of the part of the air inlet pipe 3 located inside the water storage shell 1. The sliding pipe 5 is located inside the water storage shell 1. A dispersion shell 6 for splitting oxygen into small bubbles is communicated with the lower side of the sliding pipe 5. The dispersion shell 6 is communicated with the air inlet pipe 3 through the sliding pipe 5. Through holes are arranged on the side wall of the dispersion shell 6 in a circumferentially arrayed manner. The sealing cover 2 is fixedly connected with an air outlet pipe 7. The air outlet pipe 7 communicates with the closed space formed by the water storage shell 1 and the sealing cover 2. A gas blocking plate 8 is rotatably connected to the inner side of the air outlet pipe 7, and the two are in sealing cooperation to prevent the oxygen in the water storage shell 1 from leaking. A fixing shell 9 is communicated with the upper side of the air outlet pipe 7. A measuring ball 10 is slidably connected to the inner side of the fixing shell 9. The fixing shell 9 is made of transparent material for facilitating the observation of the position of the measuring ball 10. The gas blocking plate 8 is horizontally located between the fixing shell 9 and the sealing cover 2. A depth self-adjusting mechanism 11 for adjusting the position of the dispersion shell 6 is arranged on the sealing cover 2.

[0020] Please refer to Figures 1 and Figures 3-5 , the depth self-adjusting mechanism 11 includes a fixing rod 1101. The fixing rod 1101 consists of a round rod and a disc. The round rod part of the fixing rod 1101 is hermetically slidably connected to the sealing cover 2. The upper part of the side wall of the sliding pipe 5 is fixedly connected to the lower side of the round rod part of the fixing rod 1101 through a mounting plate. A rack is arranged on the upper side of the disc part of the fixing rod 1101. Two first fixing plates 1102 distributed in a left-right mirror image are fixedly connected to the upper side of the sealing cover 2. A rotating rod 1103 is rotatably connected by the two first fixing plates 1102 together. A gear meshing with the rack on the upper side of the disc part of the fixing rod 1101 is arranged on the rotating rod 1103.

[0021] Please refer to Figure 1 and Figure 6 , a regulating handle 1104 provided with a gear is rotatably connected to the air outlet pipe 7. The gear on the regulating handle 1104 is located outside the air outlet pipe 7. The regulating handle 1104 is fixedly connected to the gas blocking plate 8. A transmission rack 1105 meshing with the gear on the regulating handle 1104 is slidably connected to the upper side of the air outlet pipe 7 through a mounting frame. A second fixing plate 1106 is fixedly connected to the upper side of the sealing cover 2. A rotating disc 1107 is rotatably connected to the second fixing plate 1106. A transmission rod 1108 is in spline connection with the rotating disc 1107. The transmission rack 1105 is rotatably connected to the transmission rod 1108 through a mounting plate.

[0022] Please refer to Figure 5 and Figure 6 On the upper side of the plugging cover 2, a power member 1109 is fixedly connected through a mounting frame. A motor and a speed reduction mechanism are arranged inside the power member 1109. The output shaft of the motor is fixedly connected to the input shaft of the speed reduction mechanism. The output shaft of the speed reduction mechanism in the power member 1109 is fixedly connected with a first transmission wheel 1110. The first transmission wheel 1110 is a frustum-shaped friction wheel. The cross-sectional radius of the first transmission wheel 1110 gradually decreases from the left front side to the right rear side. A second transmission wheel 1111 is fixedly connected to the transmission rod 1108. The second transmission wheel 1111 is a disc-shaped friction wheel. The first transmission wheel 1110 and the second transmission wheel 1111 are driven by extrusion friction. The transmission rod 1108 is splined with a first pulley 1112. The upper side of the plugging cover 2 is rotatably connected to the first pulley 1112 through a mounting frame. A second pulley 1113 is fixedly connected to the rotating rod 1103. The first pulley 1112 is driven by a belt to the second pulley 1113.

[0023] When using this device to assist the patient in breathing with oxygen, the user first installs the right end of the air inlet pipe 3 to the outlet pipe of the compressed oxygen cylinder, and then connects the tail end of the nasal oxygen tube to the left side of the air outlet pipe 7. At this time, the installation of this device is completed.

[0024] After the installation of this device is completed, the user rotates the water storage shell 1 and unscrews the water storage shell 1. The user will pour an appropriate amount of sterile water into the water storage shell 1. After the sterile water is poured, the user resets the water storage shell 1. At this time, the distance between the water level in the water storage shell 1 and the dispersion shell 6 is the optimal range for oxygen humidification. Then the air outlet valve at the top of the oxygen cylinder is opened. Then the user adjusts the pressure reducing member 4 to reduce the pressure of the compressed oxygen in the oxygen cylinder and deliver it into the air inlet pipe 3. The decompressed oxygen flows through the air inlet pipe 3 into the sliding pipe 5 and the dispersion shell 6. The oxygen flows through the through holes circumferentially arranged on the dispersion shell 6 into the sterile water in the water storage shell 1. The oxygen is humidified by the sterile water in the water storage shell 1 and then flows upward into the air outlet pipe 7. At this time, the user rotates the adjustment handle 1104 counterclockwise. The adjustment handle 1104 drives the air blocking plate 8 to rotate counterclockwise. The humidified oxygen flows leftward through the gap between the air outlet pipe 7 and the air blocking plate 8. At the same time, the humidified oxygen drives the metering ball 10 to move upward. The user observes the position of the metering ball 10 in the fixed shell 9 to determine the oxygen flow rate in the air outlet pipe 7. The oxygen flows leftward through the air outlet pipe 7 into the nasal breathing tube. Then the user probes the flow rate at the outlet of the nasal breathing tube with the hand. After the oxygen flow rate is stable, the user wears the nasal breathing tube on the patient's nose to assist the patient in breathing.

[0025] When using this device to humidify oxygen, the user activates the power component 1109. The output shaft of the power component 1109 drives the first transmission wheel 1110 to rotate. The first transmission wheel 1110 drives the second transmission wheel 1111 to rotate in a frictional manner. The second transmission wheel 1111 drives the transmission rod 1108 to rotate. The transmission rod 1108 drives the first pulley 1112 to rotate. The first pulley 1112 drives the second pulley 1113 to rotate through a belt. The second pulley 1113 drives the rotating rod 1103 and the gear thereon to rotate. The gear on the rotating rod 1103 meshes with the rack on the fixed rod 1101 and drives the fixed rod 1101 to move downward. The fixed rod 1101 drives the sliding tube 5 and the dispersion shell 6 to move downward together. The distance that the dispersion shell 6 moves downward is equal to the current consumption of sterile water (that is, the distance between the lower side of the dispersion shell 6 and the water surface of the sterile water is always equal), thus ensuring the stable humidification effect of the sterile water on oxygen. Through the cooperation of the sliding tube 5 and the air inlet pipe 3, the position of the dispersion shell 6 in the water storage shell 1 is adjusted according to the usage time of this device, so that the distance between the dispersion shell 6 and the water surface of the sterile water is always within a stable range, ensuring the humidification effect of this device on oxygen.

[0026] Since the consumption of sterile water is proportional to the oxygen flow rate, in order to accurately control the consumption of sterile water, the following operations need to be carried out: During the process of adjusting the flow rate in the outlet pipe 7 above, the user rotates the adjustment handle 1104. The gear on the adjustment handle 1104 meshes with the transmission rack 1105 and drives the transmission rod 1108 to move leftward. The transmission rod 1108 drives the second transmission wheel 1111 to move leftward, thereby increasing the transmission ratio between the first transmission wheel 1110 and the second transmission wheel 1111 (that is, the transmission ratio between the first transmission wheel 1110 and the second transmission wheel 1111 is proportional to the flow rate in the outlet pipe 7), so that the distance between the lower side of the dispersion shell 6 and the sterile water horizontal plane is always stable. As the patient gradually consumes more humidified oxygen, the amount of sterile water in the water storage shell 1 gradually decreases, and the dispersion shell 6 gradually moves downward until the lower side of the dispersion shell 6 touches the lower side of the water storage shell 1. At this time, the amount of sterile water is insufficient. The user prepares a new water storage shell 1 filled with sterile water. Subsequently, the user exchanges the two water storage shells 1. Then the user turns off the power component 1109. At the same time, the user controls the fixed rod 1101 to move upward and reset. After the reset is completed, the user restarts the power component 1109. At this time, the sterile water replacement is completed. Through the cooperation of the first transmission wheel 1110 and the second transmission wheel 1111, the moving speed of the dispersion shell 6 is adjusted in real time according to the real-time oxygen consumption, ensuring the stability of the oxygen humidification degree.

[0027] After the device is used up, the user will turn off the power component 1109. The user drives the control fixing rod 1101 to drive the dispersion shell 6, the sliding tube 5 and the parts thereon to move upward and reset. The user closes the air outlet valve at the top of the compressed oxygen cylinder. At the same time, the user turns the adjustment handle 1104 clockwise, and the adjustment handle 1104 drives the air blocking plate 8 to reset. Subsequently, the user removes the water storage shell 1 and simultaneously cleans and disinfects the inner sides of the water storage shell 1 and the plugging cover 2. After the treatment, the user reinstalls the water storage shell 1 to the plugging cover 2. At this time, the device is used up.

[0028] In the prior art, the working state of the oxygen inhaler needs to be regularly checked by medical staff or family members (i.e., the sterile water volume in the humidifying bottle and the oxygen volume in the oxygen compression bottle). If the sterile water volume in the humidifying bottle or the oxygen volume in the oxygen compression bottle is insufficient and the medical staff or family members do not replace it, it will lead to a decrease in the oxygen humidifying effect or insufficient oxygen, thus affecting the health of the patient.

[0029] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 1 、 Figure 7 and Figure 8 , and further includes a monitoring and alarming mechanism 12 for monitoring the oxygen volume and water volume. The monitoring and alarming mechanism 12 is arranged on the fixing rod 1101. The monitoring and alarming mechanism 12 includes a sliding sleeve 1201. The sliding sleeve 1201 is composed of a cylinder and a rectangular plate. The cylinder part of the sliding sleeve 1201 is slidably connected to the fixing rod 1101. The cylinder part of the sliding sleeve 1201 is in limit fit with the fixing disk part of the fixing rod 1101. A spring is arranged between the cylinder part of the sliding sleeve 1201 and the plugging cover 2. A fixing block 1202 is fixedly connected to the upper side of the plugging cover 2. A button that is in extrusion fit with the rectangular plate part of the sliding sleeve 1201 is arranged on the fixing block 1202. A buzzer 1203 that is electrically connected to the button on the fixing block 1202 is fixedly connected to the upper side of the plugging cover 2.

[0030] Please refer to Figure 7 and Figure 8 , the fixing shell 9 is slidably connected with a first sliding frame 1204. The first sliding frame 1204 is composed of a round rod and a rectangular plate. The round rod part of the first sliding frame 1204 is fixedly connected to the metering ball 10. A trigger rod 1205 located outside the fixing shell 9 is fixedly connected to the rectangular plate part of the first sliding frame 1204. The upper side of the air outlet pipe 7 is slidably connected with a second sliding frame 1206 through a mounting rod. A button that is in extrusion fit with the trigger rod 1205 is arranged on the second sliding frame 1206. The button on the second sliding frame 1206 is electrically connected to the buzzer 1203. The transmission rod 1108 is rotatably connected with a third fixing plate 1207 that is slidably connected to the second sliding frame 1206. A spring is arranged between the third fixing plate 1207 and the second sliding frame 1206, and in the initial state, the spring between the two is in a compressed state.

[0031] When the patient uses this device to assist breathing, the fixed rod 1101 gradually moves downward over time until the upper fixed disk part of the fixed rod 1101 contacts the sliding sleeve 1201. The fixed rod 1101 drives the sliding sleeve 1201 to move downward, and at the same time, compresses the spring between the sliding sleeve 1201 and the plugging cover 2. When the lower side of the dispersion shell 6 contacts the inner bottom surface of the water storage shell 1, the sliding sleeve 1201 contacts and presses the button on the fixed block 1202, and the button on the fixed block 1202 activates the buzzer 1203. The buzzer 1203 emits a sound to remind medical staff or family members to come and check this device, so as to replace the water storage shell 1. By means of the sliding sleeve 1201, the total amount of sterile water in the water storage shell 1 is monitored. After the sterile water is insufficient to maintain the oxygen humidification effect, a signal is sent to personnel in the first time, so as to maintain the humidification effect of this device on oxygen.

[0032] When this device is in normal use, the metering ball 10 moves upward under the drive of the humidified oxygen. The metering ball 10 drives the first sliding frame 1204 to move upward. When the user rotates the air blocking plate 8 counterclockwise, the transmission rod 1108 drives the third fixing plate 1207 to move leftward. The third fixing plate 1207 drives the second sliding frame 1206 to move leftward through the spring until the button on the second sliding frame 1206 moves leftward to the lower side of the trigger rod 1205, and at this time, it is ready.

[0033] If the amount of oxygen in the oxygen cylinder gradually decreases as this device is used, the amount of humidified oxygen decreases synchronously (that is, the oxygen flow rate in the air outlet pipe 7 decreases synchronously). The metering ball 10 gradually moves downward as the oxygen flow rate decreases. The metering ball 10 drives the first sliding frame 1204 and the trigger rod 1205 to move downward. The trigger rod 1205 contacts and presses the button on the second sliding frame 1206. The button on the second sliding frame 1206 activates the buzzer 1203. The buzzer 1203 emits a sound to remind medical staff or family members to come and check this device, so as to replace the oxygen cylinder. By means of the cooperation between the trigger rod 1205 and the second sliding frame 1206, the amount of oxygen is monitored, so that when the oxygen in the oxygen cylinder is consumed completely, personnel can be timely informed to handle it, improving the use safety of this device.

[0034] During the use of the existing oxygen respirator, if this device shakes due to external factors (external factors include but are not limited to: the oxygen respirator on the ambulance shakes when the ambulance brakes or starts), there will be a phenomenon that the sterile water in the humidifying bottle splashes into the nasal breathing tube, so that the sterile water flows into the patient's trachea along with the oxygen, resulting in the patient coughing and choking, affecting the patient's physical health.

[0035] Embodiment 3: On the basis of Embodiment 2, please refer to Figure 2 、 Figure 5 、Figure 9 and Figure 10 On the upper part outside the sliding tube 5, two fixed sleeves 13 are fixedly connected in an up-and-down mirror image distribution. Four first shielding plates 14 are fixedly connected to the upper fixed sleeve 13 in a circumferentially arrayed distribution. Four second shielding plates 15 are fixedly connected to the lower fixed sleeve 13 in a circumferentially arrayed distribution. The four first shielding plates 14 and the four second shielding plates 15 are staggered in the circumferential direction. Moreover, the shielding area of the first shielding plate 14 in the horizontal direction is larger than the area of the gap between two adjacent second shielding plates 15 in the horizontal direction. The lower sides of the first shielding plate 14 and the second shielding plate 15 are both located in the horizontal plane, while their upper sides are inclined upward from the side close to the axis of the sliding tube 5 to the side far from the axis of the sliding tube 5, resulting in the distance between the first shielding plate 14 and the adjacent second shielding plate 15 gradually decreasing from the side close to the axis of the sliding tube 5 to the side far from the axis of the sliding tube 5 in the vertical direction. While ensuring a sufficient oxygen circulation area, it prevents the sterile water on the circumferential side from splashing upward.

[0036] During the use of this device, if the device suddenly shakes, the sterile water in the water storage shell 1 is driven by the water storage shell 1 to shake. When the sterile water shakes, it flows upward along the inner wall of the water storage shell 1. The upward flowing sterile water contacts the lower sides of the four first shielding plates 14 and the four second shielding plates 15, and after being blocked by the lower sides of the four first shielding plates 14 and the four second shielding plates 15 on the lower side, it falls back into the water storage shell 1 again. When the sterile water in the water storage shell 1 shakes, the upward movement distance and water volume of the sterile water in the circumferential direction are the largest. And the distance between the first shielding plate 14 and the adjacent second shielding plate 15 gradually decreases from the center of the water storage shell 1 to the outside, thus preventing the sterile water from splashing into the nasal tube. Through the cooperation of the first shielding plate 14 and the second shielding plate 15, the sterile water in the water storage shell 1 is blocked, preventing the sterile water from splashing into the nasal tube due to shaking and protecting the safety of the patient.
