Description

Technical Field

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

[0002] Pure oxygen is often dry when delivered. 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. In addition, the solubility of humidified oxygen will increase, which helps it to be better absorbed by the blood, thereby improving the utilization rate of oxygen.

[0003] In the current process of humidifying oxygen, since the angle of the oxygen tank body will keep changing during oxygen inhalation, when the oxygen tank body is tilted, when the oxygen is humidified by the current humidifying device, some oxygen will not enter the sterile water, resulting in insufficient oxygen humidification. In addition, it is currently not convenient to adjust the degree of oxygen humidification according to the user's requirements. Summary of the invention

A driving vertical plate is fixedly installed on the pressing plate. A protrusion is provided on the driving vertical plate. The protrusion on the driving vertical plate contacts the arc-shaped end of the hollow tube.

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

[0010] Furthermore, 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 tube, a lower cover and a porous sleeve. A middle connecting pipe is installed on the side of the bottom cover close to the hollow handle, the middle connecting pipe is connected to 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 connected through the hose, the hose passes through the hollow sliding rod, and a swing pipe is installed at the other end of the middle connecting pipe.

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

[0012] Furthermore, it also includes an adjustment mechanism, which is arranged on the lower cover and the porous sleeve. The adjustment mechanism is used to adjust the amount of air discharged by the one-way air intake valve within a certain period of time. The adjustment mechanism includes a rotary rod, a fan-shaped baffle and a knob. A rotary rod is rotatably arranged between the lower cover and the porous sleeve. A knob is installed at the lower end of the rotary rod. The knob is located at the outer bottom of the porous sleeve. A fan-shaped baffle is installed at the upper end of the rotary rod. The fan-shaped baffle is tightly fitted with the inner bottom of the lower cover.

[0013] Furthermore, it also includes an indicator circular plate and a fan-shaped movable plate. An indicator circular plate is installed on the outer bottom of the porous sleeve, and the axis of the indicator circular plate coincides with the axis of the one-way air intake valve.

[0015] Beneficial effects of the present invention are as follows: 1. The nozzle is driven to move downward by pressing the cover, and the oxygen in the oxygen tank body is ejected through the nozzle and then passes through the hollow tube, the hose, the middle pipe, the swing pipe in sequence and then enters the closed cavity formed between the upper cover, the corrugated rubber tube and the lower cover. Then the oxygen enters the porous sleeve through the one-way air inlet valve and is discharged from the exhaust holes on the porous sleeve into the sterile water and forms bubbles. The formed bubbles rise upward 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 dry oxygen and reduces irritation to the respiratory tract.

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

[0017] 3. By controlling the degree to which the fan-shaped baffle covers the one-way air inlet valve, the flow rate of oxygen discharged from the one-way air inlet valve can be controlled, the drainage volume of the upper cover, the corrugated rubber tube and the lower cover can be adjusted, and then the buoyancy of the upper cover, the corrugated rubber tube and the lower cover can be adjusted 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 time for oxygen to rise in the sterile water can be controlled, so that the degree of oxygen humidification can be more conveniently controlled according to the operator's requirements.

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

[0035] The pressing mechanism includes a hollow slide rod 71, a pressing cover 72, a return spring 73 and a pressing plate 74. A hollow slide rod 71 is slidably provided on the hollow handle 2, and the hollow slide rod 71 will slide up and down along the hollow handle 2.

A pressing plate 74 is installed on the lower part of the hollow slide rod 71, and the pressing plate 74 slides 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 of the pressing cover 72. The slider 81 will slide horizontally along the pressing cover 72. A transverse spring 82 is respectively connected between the slider 81 and the two sides of the pressing cover 72. A hollow tube 83 is fixedly installed in the middle of the slider 81. One end of the hollow tube 83 is opened, and the other end of the hollow tube 83 is an arc-shaped closed end. A driving vertical plate 84 is fixedly installed on the pressing plate 74. A protrusion is provided on the driving vertical plate 84, and 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 a middle pipe 91, a hose 92, a swing pipe 93, a one-way air inlet valve 94, an upper cover 95, a corrugated rubber tube 96, a lower cover 97 and a porous sleeve 98. A middle pipe 91 is installed on the side of the bottom cover 4 close to the hollow handle 2. The middle pipe 91 is connected to the bottom cover 4. A hose 92 is connected between the middle pipe 91 and the hollow pipe 83. The middle pipe 91 is connected to the hollow pipe 83 through the hose 92. The hose 92 passes through the hollow slide bar 71. A swing pipe 93 is installed at the other end of the middle pipe 91. The materials of the hose 92 and the swing pipe 93 are both edible silica gel. An upper cover 95 is installed at the other end of the swing pipe 93. A corrugated rubber tube 96 is installed at the bottom, and a lower cover 97 is installed at the lower part of the corrugated rubber tube 96. A closed cavity is formed between the upper cover 95, the corrugated rubber tube 96 and the lower cover 97. The swing pipe 93 is connected with the closed cavity formed between 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 plurality of exhaust holes are evenly spaced at the bottom of the porous sleeve 98. A one-way air inlet valve 94 is installed on the lower cover 97. The porous sleeve 98 is connected with the closed cavity formed between the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 through the one-way air inlet 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 the device to humidify oxygen, the operator first unscrews the liquid storage tank 6 from the bottom cover 4, adds an appropriate amount of sterile water into the liquid storage tank 6, and then screws the liquid storage tank 6 back onto the bottom cover 4. Since the porous sleeve 98 is made of 316 stainless steel, the porous sleeve 98 has a large mass. 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 slide bar 71 away from the hollow handle 2, and the reset spring 73 is stretched accordingly. Then the operator aligns the bottom of the oxygen tank body 1 with the bottom cover 4, and the nozzle 111 with the hollow tube 83. Since the arc-shaped fixing plate 3 has toughness, the arc-shaped fixing plate 3 is in contact with the oxygen tank body 1. After the oxygen tank body 1 is completely put in, the arc-shaped fixing plate 3 will return to its initial state, and then the operator releases the pressing cover 72 and the hollow slide bar 71. Under the action of the reset spring 73, the pressing cover 72 and the hollow slide bar 71 move toward the direction close to the hollow handle 2, and the oxygen tank body 1 can be fixed by the arc-shaped fixing plate 3, the bottom cover 4 and the pressing cover 72. The operator then clamps the breathing mask into the exhaust check valve 5; then the operator holds the hollow handle 2 to align the breathing mask with the nose, and the operator's thumb presses the pressing plate 74 downward, and the pressing plate 74 first drives the driving vertical plate 84 to move downward, and the protrusion on the driving vertical plate 84 contacts the arc surface of the hollow tube 83. , the hollow tube 83 and the slider 81 will move toward the direction close to the nozzle 111, and the transverse spring 82 will be stretched accordingly. After the hollow tube 83 moves, it will be aligned with the nozzle 111 and fit tightly. The operator continues to press the pressing plate 74 downward, and the pressing plate 74 drives the hollow slide bar 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, and the pressing cover 72 drives the nozzle 111 to move downward. The oxygen in the oxygen tank body 1 is ejected through the nozzle 111 and passes through the hollow tube 83, the hose 92, the middle pipe 91, the swing pipe 93 in sequence, and then enters the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 to form a The oxygen then enters the porous sleeve 98 through the one-way air inlet 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 upward in the sterile water. During the rising process, the bubbles come into contact with the surrounding sterile water. As the bubbles rise and burst in the sterile water, water vapor is released into the oxygen to increase the humidity of the oxygen. Through this process, the oxygen gains moisture and increases the humidity, ensuring that the patient will not feel dry when inhaling. The humidified oxygen is usually milder than dry oxygen and reduces irritation to the respiratory tract. The humidified oxygen is discharged into the breathing mask through the exhaust one-way valve 5 for the operator to inhale oxygen.As the oxygen is continuously humidified, the sterile water in the liquid storage tank 6 will continue to decrease. However, since the oxygen tank body 1 is not necessarily in a horizontal state when in use, when the oxygen tank body 1 is in an inclined state, the horizontal plane in the liquid storage tank 6 is also in an inclined state relative to the liquid storage tank 6. Because the porous sleeve 98 is made of 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, so the center of gravity will be distributed on the porous sleeve 98. No matter how the horizontal plane changes, the porous sleeve 98 can be located below the water surface, so that the oxygen can be fully discharged into the sterile water, avoiding the situation where the oxygen is directly discharged for the operator to breathe without passing through the sterile water, thereby improving the effect of oxygen humidification; when the operator does not require oxygen inhalation, the operator's thumb releases the pressing plate 74, and under the action of the transverse spring 82, the arc surface of the hollow tube 83 hits the protrusion on the driving vertical plate 84, and the driving vertical plate 84 and the pressing plate 74 will move upward Under the action of the reset spring 73, the hollow slide bar 71, the pressing cover 72, the slider 81, the transverse spring 82, the hollow tube 83 and the driving vertical plate 84 move upward to reset, and the nozzle 111 also moves upward to reset, and the oxygen in the oxygen tank body 1 is no longer discharged. When the oxygen in the oxygen tank body 1 is consumed, the operator pulls the pressing cover 72 and the hollow slide bar 71 to move away from the hollow handle 2, and then the operator takes a new bottle of oxygen tank body 1 and puts it in. After that, the operator releases the pressing cover 72 and the hollow slide bar 71. Under the action of the return spring 73, the pressing cover 72 and the hollow slide bar 71 move toward the direction close to the hollow handle 2. The new oxygen tank body 1 can be fixed by the arc-shaped fixing plate 3, the bottom cover 4 and the pressing cover 72. After 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 into the liquid storage tank 6, and then screws the liquid storage tank 6 back onto the bottom cover 4. ;

[0041] Embodiment 2: Based on embodiment 1, Figure 9-13 As shown, it also includes an adjustment mechanism, which is arranged on the lower cover 97 and the porous sleeve 98. The adjustment mechanism is used to adjust the amount of air discharged by the one-way air intake valve 94 within a certain period of time. The adjustment mechanism includes a rotary rod 101, a fan-shaped baffle 102 and a knob 103. A rotary rod 101 is rotatably provided between the lower cover 97 and the porous sleeve 98. A knob 103 is installed at the lower end of the rotary rod 101. The knob 103 is located at the outer bottom of the porous sleeve 98. A fan-shaped baffle 102 for covering the one-way air intake valve 94 is installed at the upper end of the rotary rod 101. The fan-shaped baffle 102 is tightly fitted with the inner bottom of the lower cover 97.

[0042] Initially, the fan-shaped baffle 102 does not block the one-way air intake valve 94. The operator pinches the knob 103 and rotates it. The knob 103 drives the rotary rod 101 and the fan-shaped baffle 102 to rotate. The fan-shaped baffle 102 will cover the one-way air intake valve 94 after rotation. By controlling the degree to which the fan-shaped baffle 102 covers the one-way air intake valve 94, the flow rate of oxygen passing through the one-way air intake valve 94 can be controlled. When the flow rate of oxygen passing through the one-way air intake valve 94 is small, the oxygen will gradually fill the closed cavity formed between the upper cover 95, the corrugated rubber tube 96 and the lower cover 97, and the corrugated rubber tube 96 will expand accordingly, so that the upper cover 95 and the corrugated rubber tube 96 can be increased. The displacement of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be adjusted, thereby increasing the buoyancy of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97. By controlling the degree to which the fan-shaped baffle 102 covers the one-way air inlet valve 94, the flow rate of oxygen discharged from the one-way air inlet valve 94 can be controlled. The displacement of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97 can be adjusted, thereby adjusting the buoyancy of the upper cover 95, the corrugated rubber tube 96 and the lower cover 97, thereby controlling 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 time for oxygen to rise in the sterile water can be controlled, so that the degree of oxygen humidification can be more conveniently controlled according to the operator's requirements.

[0043] Embodiment 3: Based on embodiment 2, Figure 7-Figure 13 As shown, it also includes an indicator circular plate 12 and a fan-shaped movable plate 13. An indicator circular plate 12 is installed on the outer bottom of the porous sleeve 98. The axis of the indicator circular plate 12 coincides with the axis of the one-way air intake valve 94. A fan-shaped movable plate 13 is installed at the lower part of the rotating rod 101. The fan-shaped movable plate 13 is located directly below the fan-shaped baffle 102, and the projection of the fan-shaped movable plate 13 from top to bottom coincides with the fan-shaped baffle 102.

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

[0045] When the rotary rod 101 rotates, it can drive the fan-shaped movable plate 13 to move. By observing the degree to which the fan-shaped movable plate 13 blocks the indicating circular plate 12, the degree to which the fan-shaped baffle 102 blocks the one-way air intake valve 94 can be intuitively observed, thereby facilitating the operator to adjust the flow rate of oxygen discharged by the one-way air intake valve 94.

[0046] After the hollow tube 83 and the rubber ring 11 move, they will be aligned with the nozzle 111 and fit tightly. The contact between the rubber ring 11 and the nozzle 111 can improve the sealing between the hollow tube 83 and the nozzle 111 to avoid oxygen leakage. The liquid level of the sterile water in the liquid storage tank 6 can be intuitively observed through the transparent observation plate 14. 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 with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
