Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a humidifying device based on canned oxygen. Background Art

[0002] Pure oxygen is often dry when being transported. Long-term inhalation of dry oxygen may cause dryness and irritation of the respiratory mucosa. Humidification can relieve this discomfort and protect the respiratory tract. Moreover, the solubility of humidified oxygen will increase, which helps to be better absorbed by the blood, thereby improving the utilization rate of oxygen.

[0003] During the current process of humidifying oxygen, since the angle of the oxygen cylinder body will always change during the oxygen inhalation process, when the oxygen cylinder body is tilted, when the current humidifying device is used to humidify oxygen, it is easy for some oxygen not to enter the sterile water, resulting in insufficient humidification of oxygen. Moreover, it is not convenient to adjust the degree of oxygen humidification according to the requirements of users currently. Summary of the Invention

[0004] In order to overcome the drawback that when the current humidifying device is used to humidify oxygen, it is easy for some oxygen not to enter the sterile water, resulting in insufficient humidification of oxygen, and it is not convenient to adjust the degree of oxygen humidification according to the requirements of users currently. To solve the above problems, a humidifying device based on canned oxygen is provided. When the oxygen cylinder body is tilted for use, oxygen can be fully humidified, and the degree of oxygen humidification can be conveniently and quickly adjusted according to the requirements of users for the degree of oxygen humidification.

A nozzle is provided on the upper part of the oxygen cylinder body. Four arc-shaped fixing plates are installed on one side of the hollow handle close to the oxygen cylinder body. A bottom cover is installed on the lower part of the hollow handle. An exhaust check valve is installed on one side of the bottom cover away from the hollow handle. The exhaust check valve is communicated with the lower cover. A liquid storage tank is connected to the lower cover by thread. A pressing mechanism is provided on the hollow handle. The pressing mechanism is used to press the nozzle. An alignment mechanism is provided on the pressing mechanism. The alignment mechanism is used to align the nozzle of the nozzle. A humidifying mechanism is provided on the bottom cover, the liquid storage tank, the pressing mechanism, and the alignment mechanism. The humidifying mechanism is used to humidify the ejected oxygen.

[0006] Furthermore, the arc-shaped fixing plate is made of elastic ABS material.

[0007] Further, the pressing mechanism includes a hollow sliding rod, a pressing cover, a return spring, and a pressing plate. A hollow sliding rod is slidably arranged on the hollow handle. A pressing cover is fixedly installed on the upper part of the hollow sliding rod. The pressing cover is located directly above the nozzle. Two return springs are connected between the lower part of the hollow sliding rod and the hollow handle. A pressing plate is installed at the lower part of the hollow sliding rod. The pressing plate slidably passes through the hollow handle.

[0008] Further, the alignment mechanism includes a slider, a transverse spring, a hollow tube, and a driving vertical plate. A slider is slidably arranged between the two sides inside the pressing cover. A transverse spring is respectively connected between the slider and the two sides of the pressing cover. A hollow tube is fixedly installed in the middle of the slider. One end of the hollow tube is open, and the other end of the hollow tube is arc-shaped and closed. A driving vertical plate is fixedly installed on the pressing plate. A protrusion is arranged on the driving vertical plate. The protrusion on the driving vertical plate contacts the arc-shaped end of the hollow tube.

[0009] Further, the elastic coefficient of the return spring is greater than that of the transverse spring.

[0010] Further, the humidifying mechanism includes a middle connecting pipe, a hose, a swing pipe, a one-way air inlet valve, an upper cover, a corrugated rubber pipe, a lower cover, and a porous sleeve. A middle connecting pipe is installed on one side of the bottom cover close to the hollow handle. The middle connecting pipe is communicated with the bottom cover. A hose is connected between the middle connecting pipe and the hollow tube. The middle connecting pipe and the hollow tube are communicated through the hose. The hose passes through the hollow sliding rod. A swing pipe is installed at the other end of the middle connecting pipe. The materials of the hose and the swing pipe are both edible silica gel. An upper cover is installed at the other end of the swing pipe. A corrugated rubber pipe is installed at the lower part of the upper cover. A lower cover is installed at the lower part of the corrugated rubber pipe. A sealed cavity is formed among the upper cover, the corrugated rubber pipe, and the lower cover. The swing pipe is communicated with the sealed cavity formed among the upper cover, the corrugated rubber pipe, and the lower cover. A porous sleeve is installed at the bottom of the lower cover. A number of exhaust holes are evenly spaced at the bottom of the porous sleeve. A one-way air inlet valve is installed on the lower cover. The porous sleeve is communicated with the sealed cavity formed among the upper cover, the corrugated rubber pipe, and the lower cover through the one-way air inlet valve.

[0011] Further, the material of the porous sleeve is 316 stainless steel, and the upper cover and the lower cover are made of polyethylene.

[0012] Further, an adjusting mechanism is further included. The adjusting mechanism is arranged on the lower cover and the porous sleeve. The adjusting mechanism is used to adjust the amount of air discharged by the one-way air inlet valve within a certain time. The adjusting mechanism includes a rotating rod, a sector baffle, and a knob. A rotating rod is rotatably arranged between the lower cover and the porous sleeve. A knob is installed at the lower end of the rotating rod. The knob is located at the outer bottom of the porous sleeve. A sector baffle is installed at the upper end of the rotating rod. The sector baffle is closely attached to the inner bottom of the lower cover.

[0013] Further, it also includes an indicating circular plate and a sector-shaped movable plate. An indicating circular plate is installed at the outer bottom of the porous sleeve, and the axis of the indicating circular plate coincides with the axis of the one-way intake valve. A sector-shaped movable plate is installed at the lower part of the rotating rod, and the sector-shaped movable plate is directly below the sector-shaped baffle. The projection of the sector-shaped movable plate from top to bottom coincides with the sector-shaped baffle.

[0014] Further, it also includes a rubber ring and a transparent observation plate. A rubber ring is embedded at the opening of the hollow tube, and a transparent observation plate is embedded and installed on one side of the liquid storage tank.

[0015] Advantages of the present invention: 1. By pressing the cover to drive the nozzle to move downward, the oxygen in the oxygen tank body is sprayed out through the nozzle and then passes through the hollow tube, hose, middle connecting pipe, and swing pipe in sequence and enters the sealed cavity formed between the upper cover, corrugated rubber pipe, and lower cover. Then the oxygen enters the porous sleeve through the one-way intake valve and is discharged from the exhaust holes on the porous sleeve into the sterile water to form bubbles. The formed bubbles rise in the sterile water. During the rising process, the bubbles contact the surrounding sterile water. As the bubbles rise and burst in the sterile water, water vapor will be released into the oxygen, increasing the humidity of the oxygen. Through this process, the oxygen obtains moisture and increases the humidity, ensuring that the patient will not feel dry when inhaling. The humidified oxygen is usually milder than the dry oxygen, reducing the irritation to the respiratory tract.

[0016] 2. When the oxygen tank body is in an inclined state, the water level in the liquid storage tank is also in an inclined state relative to the liquid storage tank. Since the porous sleeve is made of 316 stainless steel and the upper cover and lower cover are made of polyethylene, the density of the porous sleeve is greater than that of the upper cover and lower cover. Therefore, the center of gravity will be distributed on the porous sleeve. No matter how the water level changes, the porous sleeve can be located below the water surface, so that the oxygen can be fully discharged into the sterile water, avoiding the situation that the oxygen is directly discharged without passing through the sterile water for the operator to breathe, and improving the oxygen humidification effect.

[0017] 3. By controlling the degree to which the sector-shaped baffle covers the one-way intake valve to control the oxygen discharge flow rate of the one-way intake valve, the drainage volume of the upper cover, corrugated rubber pipe, and lower cover can be adjusted, and then the buoyancy of the upper cover, corrugated rubber pipe, and lower cover can be adjusted, so as to control the position of the porous sleeve in the sterile water. By adjusting the position of the porous sleeve in the sterile water, the rising time of the oxygen in the sterile water can be controlled, so that it is more convenient to control the oxygen humidification degree according to the requirements of the operator.

[0032] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0033] Embodiment 1: A humidifying device based on canned oxygen, as Figures 1-10 shown, includes a hollow handle 2, an arc-shaped fixing plate 3, a bottom cover 4, an exhaust check valve 5, a liquid storage tank 6, a pressing mechanism, an alignment mechanism, and a humidifying mechanism. A spray head 111 is provided on the upper part of the oxygen cylinder body 1. Four arc-shaped fixing plates 3 are installed on one side of the hollow handle 2 close to the oxygen cylinder body 1. A bottom cover 4 is installed at the lower part of the hollow handle 2 through bolts. An exhaust check valve 5 is installed on one side of the bottom cover 4 away from the hollow handle 2. The exhaust check valve 5 is communicated with the lower cover 97. A liquid storage tank 6 is connected to the lower cover 97 by thread. A pressing mechanism is provided on the hollow handle 2.

The humidifying mechanism is used to humidify the sprayed oxygen.

[0034] The arc-shaped fixing plate 3 is made of elastic ABS material.

[0035] The pressing mechanism includes a hollow sliding rod 71, a pressing cover 72, a return spring 73, and a pressing plate 74. A hollow sliding rod 71 is slidably provided on the hollow handle 2. The hollow sliding rod 71 can slide up and down along the hollow handle 2. A pressing cover 72 is fixedly installed on the upper part of the hollow sliding rod 71 through bolts. The pressing cover 72 is located directly above the spray head 111. Two return springs 73 are connected between the lower part of the hollow sliding rod 71 and the hollow handle 2. A pressing plate 74 is installed at the lower part of the hollow sliding rod 71. The pressing plate 74 slidably passes through the hollow handle 2.

[0036] The alignment mechanism includes a slider 81, a transverse spring 82, a hollow tube 83, and a driving vertical plate 84. A slider 81 is slidably provided between the two sides inside the pressing cover 72. The slider 81 can slide horizontally along the pressing cover 72. A transverse spring 82 is connected between the slider 81 and the two sides of the pressing cover 72 respectively. A hollow tube 83 is fixedly installed in the middle of the slider 81. One end of the hollow tube 83 is open, and the other end of the hollow tube 83 is arc-shaped and closed. A driving vertical plate 84 is fixedly installed on the pressing plate 74. A protrusion is provided on the driving vertical plate 84. The protrusion on the driving vertical plate 84 contacts the arc-shaped end of the hollow tube 83.

[0037] The elastic coefficient of the return spring 73 is greater than the elastic coefficient of the transverse spring 82.

[0038] The humidifying mechanism includes an intermediate connecting pipe 91, a flexible hose 92, a swing pipe 93, a one-way intake valve 94, an upper cover 95, a corrugated rubber tube 96, a lower cover 97, and a porous sleeve 98. An intermediate connecting pipe 91 is installed on one side of the bottom cover 4 close to the hollow handle 2. The intermediate connecting pipe 91 is in communication with the bottom cover 4. A flexible hose 92 is connected between the intermediate connecting pipe 91 and the hollow pipe 83. The intermediate connecting pipe 91 and the hollow pipe 83 are in communication through the flexible hose 92. The flexible hose 92 passes through the hollow slide rod 71. Another swing pipe 93 is installed at the other end of the intermediate connecting pipe 91. The flexible hose 92 and the swing pipe 93 are made of food-grade silica gel. An upper cover 95 is installed at the other end of the swing pipe 93. A corrugated rubber tube 96 is installed below the upper cover 95. A lower cover 97 is installed below the corrugated rubber tube 96. A sealed cavity is formed among the upper cover 95, the corrugated rubber tube 96, and the lower cover 97. The swing pipe 93 is in communication with the sealed cavity formed among the upper cover 95, the corrugated rubber tube 96, and the lower cover 97. A porous sleeve 98 for uniformly discharging oxygen is installed at the bottom of the lower cover 97. A number of exhaust holes are evenly spaced at the bottom of the porous sleeve 98. A one-way intake valve 94 is installed on the lower cover 97. The porous sleeve 98 is in communication with the sealed cavity formed among the upper cover 95, the corrugated rubber tube 96, and the lower cover 97 through the one-way intake valve 94.

[0039] The porous sleeve 98 is made of 316 stainless steel, and the upper cover 95 and the lower cover 97 are made of polyethylene.

[0040] When using this device to humidify oxygen, the operator first unscrews the liquid storage tank 6 from the bottom cover 4. After adding an appropriate amount of sterile water into the liquid storage tank 6, the operator then screws the liquid storage tank 6 back onto the bottom cover 4. Since the material of the porous sleeve 98 is 316 stainless steel, the mass of the porous sleeve 98 is relatively large. Initially, the porous sleeve 98 will sink to the bottom of the sterile water. The operator first pulls the pressing cover 72 and the hollow sliding rod 71 and moves them away from the hollow handle 2. The return spring 73 is stretched accordingly. Then the operator aligns the bottom of the oxygen cylinder body 1 with the bottom cover 4 and the nozzle 111 with the hollow tube 83. Since the arc-shaped fixing plate 3 is flexible, the arc-shaped fixing plate 3 will deform after contacting the oxygen cylinder body 1. After the oxygen cylinder body 1 is completely placed, the arc-shaped fixing plate 3 will return to its initial state. Then the operator releases the pressing cover 72 and the hollow sliding rod 71. Under the action of the return spring 73, the pressing cover 72 and the hollow sliding rod 71 move towards the hollow handle 2. The oxygen cylinder body 1 can be fixed by the arc-shaped fixing plate 3, the bottom cover 4 and the pressing cover 72. The operator then clips the breathing mask onto the exhaust check valve 5. Then the operator holds the hollow handle 2 and aligns the breathing mask with the nose. The operator's thumb presses down the pressing plate 74. The pressing plate 74 first drives the driving vertical plate 84 to move downward. After the protrusion on the driving vertical plate 84 touches the arc surface of the hollow tube 83, the hollow tube 83 and the slider 81 will move towards the nozzle 111. The transverse spring 82 is stretched accordingly. After the hollow tube 83 moves, it will align with and closely fit the nozzle 111. The operator continues to press down the pressing plate 74. The pressing plate 74 drives the hollow sliding rod 71, the pressing cover 72, the slider 81, the transverse spring 82, the hollow tube 83 and the driving vertical plate 84 to move downward together. The return spring 73 is compressed accordingly. The pressing cover 72 drives the nozzle 111 to move downward. The oxygen in the oxygen cylinder body 1 is ejected through the nozzle 111 and then passes through the hollow tube 83, the hose 92, the middle connecting tube 91, the swing tube 93 in sequence and then enters the closed cavity formed between the upper cover 95, the corrugated rubber tube 96 and the lower cover 97. Then the oxygen enters the porous sleeve 98 through the one-way intake valve 94 and is discharged from the exhaust holes on the porous sleeve 98 into the sterile water to form bubbles. The formed bubbles rise in the sterile water. During the rising process, the bubbles contact the surrounding sterile water. As the bubbles rise and burst in the sterile water, water vapor will be released into the oxygen, increasing the humidity of the oxygen. Through this process, the oxygen obtains moisture and increases its humidity, ensuring that the patient will not feel dry when inhaling. The humidified oxygen is usually milder than the dry oxygen, reducing the irritation to the respiratory tract. The humidified oxygen is discharged into the breathing mask through the exhaust check valve 5 for the operator to inhale;As oxygen is continuously humidified, the sterile water in the liquid storage tank 6 will continuously decrease. However, since the oxygen tank body 1 may not be in a horizontal state during use, when the oxygen tank body 1 is in an inclined state, the water level in the liquid storage tank 6 is also in an inclined state relative to the liquid storage tank 6. Because the material of the porous sleeve 98 is 316 stainless steel and the upper cover 95 and the lower cover 97 are made of polyethylene, the density of the porous sleeve 98 is greater than that of the upper cover 95 and the lower cover 97. Therefore, the center of gravity will be distributed on the porous sleeve 98. No matter how the water level changes, the porous sleeve 98 can be located below the water surface, so that oxygen can be fully discharged into the sterile water, avoiding the situation that oxygen is directly discharged without passing through the sterile water for the operator to breathe, and improving the oxygen humidification effect; when the operator does not require oxygen inhalation, the operator's thumb releases the pressing plate 74. Under the action of the transverse spring 82, after the arc surface of the hollow tube 83 touches the protrusion on the driving vertical plate 84, the driving vertical plate 84 and the pressing plate 74 will move upward to reset. Under the action of the return spring 73, the hollow slide rod 71, the pressing cover 72, the slider 81, the transverse spring 82, the hollow tube 83 and the driving vertical plate 84 move upward together to reset, and the nozzle 111 will also move upward to reset, and the oxygen in the oxygen tank body 1 will no longer be discharged. When the oxygen in the oxygen tank body 1 is consumed, the operator pulls the pressing cover 72 and the hollow slide rod 71 and moves them away from the hollow handle 2, and then the operator takes a new oxygen tank body 1 and puts it in. Then the operator releases the pressing cover 72 and the hollow slide rod 71. Under the action of the return spring 73, the pressing cover 72 and the hollow slide rod 71 move toward the hollow handle 2, and the new oxygen tank body 1 can be fixed through the arc-shaped fixing plate 3, the bottom cover 4 and the pressing cover 72. When the sterile water in the liquid storage tank 6 is consumed to a certain amount, the operator unscrews the liquid storage tank 6 from the bottom cover 4, adds an appropriate amount of sterile water to the liquid storage tank 6, and then the operator screws the liquid storage tank 6 back onto the bottom cover 4.;

[0041] Embodiment 2: On the basis of Embodiment 1, as Figures 9-13 shown, it further includes an adjusting mechanism. The adjusting mechanism is arranged on the lower cover 97 and the porous sleeve 98. The adjusting mechanism is used to adjust the amount of air discharged by the one-way intake valve 94 within a certain period of time. The adjusting mechanism includes a rotating rod 101, a sector baffle 102 and a knob 103. A rotating rod 101 is rotatably arranged between the lower cover 97 and the porous sleeve 98. A knob 103 is installed at the lower end of the rotating rod 101. The knob 103 is located at the outer bottom of the porous sleeve 98. A sector baffle 102 for blocking the one-way intake valve 94 is installed at the upper end of the rotating rod 101. The sector baffle 102 is in close contact with the inner bottom of the lower cover 97.

[0042] Initially, the sector baffle 102 does not block the one-way intake valve 94. The operator pinches the knob 103 and rotates it. The knob 103 drives the rotating rod 101 and the sector baffle 102 to rotate. After the sector baffle 102 rotates, it will block the one-way intake valve 94. By controlling the degree to which the sector baffle 102 covers the one-way intake valve 94, the flow rate of oxygen passing through the one-way intake valve 94 can be controlled. When the flow rate of oxygen passing through the one-way intake valve 94 is small, the oxygen will gradually fill the sealed cavity formed between the upper cover 95, the corrugated rubber tube 96 and the lower cover 97. The corrugated rubber tube 96 will expand accordingly. In this way, the drainage volume of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be increased, and thus the buoyancy of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be increased. By controlling the degree to which the sector baffle 102 covers the one-way intake valve 94 to control the flow rate of oxygen discharged from the one-way intake valve 94, the drainage volume of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be adjusted, and further the buoyancy of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be adjusted, so as to control the position of the porous sleeve 98 in the sterile water. By adjusting the position of the porous sleeve 98 in the sterile water, the rising time of oxygen in the sterile water can be controlled, and thus it is more convenient to control the degree of oxygen humidification according to the requirements of the operator.

[0043] Embodiment 3: On the basis of Embodiment 2, as Figures 7-13 shown, it further includes an indicating circular plate 12 and a sector movable plate 13. An indicating circular plate 12 is installed at the outer bottom of the porous sleeve 98. The axis of the indicating circular plate 12 coincides with the axis of the one-way intake valve 94. A sector movable plate 13 is installed at the lower part of the rotating rod 101. The sector movable plate 13 is located directly below the sector baffle 102. The projection of the sector movable plate 13 from top to bottom coincides with the sector baffle 102.

[0044] It further includes a rubber ring 11 and a transparent observation plate 14. A rubber ring 11 is embedded at the opening of the hollow tube 83. A transparent observation plate 14 for observing the liquid level of the sterile water is embedded and installed on one side of the liquid storage tank 6.

[0045] When the rotating rod 101 rotates, it can drive the sector movable plate 13 to move. By observing the degree to which the sector movable plate 13 blocks the indicating circular plate 12, the degree to which the sector baffle 102 covers the one-way intake valve 94 can be visually observed, and thus it is convenient for the operator to adjust the flow rate of oxygen discharged from the one-way intake valve 94.

[0046] After the hollow tube 83 and the rubber ring 11 move, they will align with and closely fit the nozzle 111. By contacting the nozzle 111 through the rubber ring 11, the sealing performance between the hollow tube 83 and the nozzle 111 can be improved to avoid oxygen leakage. Through the transparent observation plate 14, the liquid level of the sterile water in the liquid storage tank 6 can be visually observed. When the sterile water is lower than the specified liquid level, the operator can add sterile water in time.

[0047] Although the present disclosure has been described only with respect to a limited number of embodiments, those skilled in the art who benefit from the present disclosure will understand that various other embodiments can be designed without departing from the scope of the present invention. Therefore, the scope of the present invention should be limited only by the appended claims.
