Description

An oxygen humidification bottle

technical field

The invention relates to the field of medical equipment, in particular to an oxygen humidification bottle.

Background technique

Oxygen humidification bottle is a kind of rehabilitation equipment and ward nursing consumables. Its main function is to humidify dry oxygen and moisturize it. It is mainly used in the oxygen supply system of the medical center, and can be supplied to medical units for emergency oxygen supply and oxygen inhalation for hypoxic patients. The oxygen inhaler has accurate flow, is convenient and safe to use, and is an essential device for oxygen treatment in hospital emergency rooms, wards and patients. The oxygen humidification bottle in the prior art is composed of a bottle body, a bottle cap, and an oxygen inlet pipe and an oxygen exhaust pipe inserted in the bottle cap.

As shown in Figure 4, the lower end of the oxygen inlet pipe is inserted into the distilled water contained in the bottle body. Oxygen flows into the distilled water through the oxygen inlet pipe to form bubbles and is discharged from the liquid level of the distilled water, and completes the humidification in the process of rising and discharging. Finally, it is collected by the oxygen exhaust pipe and discharged for the patient's inhalation. During the oxygen humidification process of this type of humidification bottle, since the lower end of the oxygen inlet pipe is directly in contact with distilled water, larger air bubbles will be formed at the lower end of the oxygen inlet pipe, and have a smaller specific surface area, and the oxygen and the Distilled water has less contact and less humidification.

On the basis of the above-mentioned oxygen humidification bottle, another kind of humidification bottle with humidification function has appeared, as shown in Figure 5. The lower end of the inlet pipe is provided with an air distribution network. A relatively thick oxygen stream in the oxygen inlet pipe is first dispersed into a plurality of thin streams through the gas distribution network, so that fine air bubbles are formed in the distilled water at the lower end of the oxygen inlet pipe. In turn, the bubbles have a larger specific surface area, so that the oxygen and distilled water are in contact with each other in a large area, so as to achieve the purpose of enhancing the humidification effect. However, the humidification effect of this type of humidification bottle is not significantly improved. The reasons are: on the one hand, the small bubbles formed at the lower end of the oxygen inlet pipe rise approximately vertically along the position close to the oxygen inlet pipe, which cannot effectively utilize the horizontal direction of the distilled water. space, so the stroke discharged from distilled water is too short, the contact time with distilled water is short, and the humidification effect is poor; on the other hand, after the small bubbles are sprayed from the lower end of the oxygen inlet pipe, the spray direction is irregular and uncontrollable, and the bubbles are discharged. The lateral range of distilled water is too narrow, so that small bubbles collide with each other to form large bubbles again, which cannot achieve the purpose of significant humidification.

SUMMARY OF THE INVENTION

The invention aims to provide an oxygen humidification bottle, which can increase the specific surface area of the contact between the oxygen bubbles and distilled water and prolong the discharge stroke of the oxygen bubbles from the distilled water, thereby significantly improving the humidification effect of oxygen.

In order to solve the above technical problems, the technical solution adopted in the present invention is as follows: an oxygen humidification bottle, comprising a bottle body, a bottle cap, and an oxygen inlet pipe and an oxygen exhaust pipe inserted in the bottle cap.

The oxygen humidification mechanism includes a rotor that is rotated and arranged on the oxygen inlet pipe, and the driving force for the rotation of the rotor is provided by the oxygen flowing in the oxygen inlet pipe. The central position of the top of the body is provided with a gas collecting groove, which is communicated with the oxygen inlet pipe and is connected with the oxygen inlet pipe in a rotating fit. There are a plurality of radially distributed air ducts, all the air ducts are arc-shaped, and all the air ducts keep the same bending direction along the circumferential direction of the rotating body.

Preferably, the multiple air distribution channels are distributed in layers along the height direction of the rotating body, the arcs of the multiple air distribution channels in any one layer are the same, and the arcs of the air distribution channels in any two layers are different.

beneficial effect

In the present invention, a rotor is arranged at the lower end of the oxygen inlet pipe, and the rotor is provided with a gas collecting tank connected with the oxygen inlet pipe and a plurality of air distribution channels connected with the gas collecting tank, and the plurality of air distribution channels are oriented in the direction Consistent arc shape and radial distribution on the cross section of the rotating body, so that the oxygen pressure can be converted into the power of the rotating body, and the air bubbles can be discharged under the rotating state of the rotating body. On the one hand, the discharged bubbles rise and discharge along the oblique direction of the distilled water area due to centrifugal force; Contact with distilled water significantly increases the humidification effect.

The flow rate of oxygen discharged in the air dividing passage with a smaller arc is faster, and the formed air bubbles are closer to the outer circumference of the bottle body; Slowly, the bubbles formed are closer to the center of the bottle. Therefore, the bubbles generated by different air passages are obviously stratified, and the width of the bottle body is effectively utilized, avoiding the formation of fine bubbles that are too concentrated and colliding to generate large bubbles, maintaining the large specific surface area of the fine bubbles, and further. The humidifying effect of the present invention is improved.

Detailed ways

As shown in FIG. 1 , an oxygen humidification bottle of the present invention includes a bottle body 3 , a bottle cap 2 , and an oxygen inlet pipe 4 and an oxygen exhaust pipe 1 inserted in the bottle cap 2 . The bottle body 3 is filled with distilled water, and the lower end of the oxygen inlet pipe 4 is inserted in the distilled water and is close to the bottom of the bottle body 3, so that the oxygen flowing through the oxygen inlet pipe 4 generates bubbles in the distilled water and fully contacts the distilled water. Then it escapes from the surface of distilled water, and is collected by the oxygen exhaust pipe 1 and then discharged from the bottle body 3 for inhalation by the patient.

Different from the humidification bottle in the prior art, the present invention is provided with an oxygen humidification mechanism at the lower end of the oxygen inlet pipe 4 . And the specific surface area of the bubbles and the travel time through the distilled water area are increased through the humidification mechanism, so that the oxygen is more fully contacted with the distilled water, and the purpose of significantly increasing the oxygen humidity is achieved.

As shown in FIG. 2 , a gas collecting groove 10 is opened at the top center of the rotor 5, and a bearing 9 is provided between the inner wall of the gas collecting groove 10 and the outer wall of the oxygen inlet pipe 4, preferably oil-free self-lubricating ceramics Bearing 9, so that the rotating body 5 can rotate flexibly with the oxygen inlet pipe 4 as the center under the action of power driving. In the present invention, the rotational power of the rotor 5 is not external, but comes from the oxygen itself flowing in the oxygen inlet pipe 4 . Since there are a plurality of radially distributed air distribution channels 7 on the rotating body 5 at the interval between the outer edge of the rotating body 5 and the air collecting groove 10 , and all the air distribution channels 7 are arc-shaped and all The air distribution channel 7 is consistent along the bending direction of the rotating body 5 in the circumferential direction. Therefore, the oxygen in the oxygen inlet pipe flows into the gas collecting tank 10 and then is discharged through the plurality of air distribution channels 7 respectively to form multiple oxygen jets in a straight direction to drive the rotor 5 to rotate. At the same time, after the oxygen jet is injected into the distilled water, bubbles are formed. Under the action of centrifugal force and the inertia of the rotating body 5, the bubbles rise obliquely and spirally along the bottle body 3, so as to increase the escape stroke and time of the bubbles and make the oxygen The purpose of full contact with distilled water.

In this embodiment, the bottom of the gas collecting tank 10 is arc-shaped, and the shape of the connecting end between the air distribution channel 7 and the gas collecting tank 10 is a bell mouth shape, so as to facilitate the introduction of oxygen flow into each air distribution channel 7 respectively. A cross-shaped gas splitting cutter 6 is provided at the air outlet position of the split air passage 7 on the outer edge of the rotor 5, which can further divide the coarser oxygen flow in the split gas passage 7 to form four finer oxygen streams. , and then travel more fine bubbles to expand the specific surface area of oxygen.

The multiple air distribution channels 7 in the present invention are distributed in layers along the height direction of the rotating body 5 , the multiple air distribution channels 7 in any layer have the same radian, and the air distribution channels 7 in any two layers have different radians. As shown in FIG. 2 and FIG. 3 , the air distribution channel 7 on the rotor 5 in this embodiment includes two layers, the upper and lower layers, and the radian of the lower air distribution channel 7 is smaller than that of the upper air distribution channel 7 (shown by the solid line in FIG. 3 ). It is the upper airway 7, and the dotted line shows the lower airway 7). Because the lower air dividing channel 7 is relatively gentle and has a small arc, the power of oxygen flowing through is always small, so that the flow rate of oxygen discharged from the air dividing channel 7 is faster, and the formed bubbles are closer to the outer periphery of the bottle body 3 . The arc of the upper air distribution channel 7 is larger, and the power loss of the oxygen flowing through is larger, so the flow rate of the discharged oxygen is slower, and the formed bubbles are also closer to the center of the bottle body 3 . Thereby, the bubbles generated by the upper and lower air separation channels 7 appear obvious stratification, and the formed bubble flows do not interfere with each other during the rising process, which effectively utilizes the width of the distilled water in the bottle body 3 and avoids the formation of too small bubbles. Concentrating and colliding to generate large air bubbles, the larger specific surface area of fine air bubbles is maintained, and the humidification effect of the present invention is further improved.

In this embodiment, on the one hand, as shown in FIG. 2 , the cross-sectional shape of the rotating body 5 is a trapezoid with a small top and a large bottom, so that the positions where the air bubbles are generated in the upper and lower air separation channels 7 have a certain interval in the horizontal direction; On the other hand, as shown in FIG. 3 , the upper and lower layers of air distribution channels 7 are staggered, so that the air outlets of the two layers of air distribution channels 7 located on the outer edge of the rotating body 5 are staggered on the outer edge of the rotating body 5 . Furthermore, the positions where the air bubbles are generated in the upper and lower air separation channels 7 have a certain interval in the axial direction of the rotating body 5 . Through the interval between the horizontal direction of the bubble generating position and the circumferential direction of the rotor 5, the layering effect of the bubbles generated by the two-layer air separation channel 7 is further improved, so as to avoid the collision of small bubbles to form large bubbles.

It should be noted that, in this embodiment, two upper and lower layers of air distribution channels 7 are arranged on the rotor 5, and any one layer contains five air distribution channels 7 for the purpose of making the description and drawings of the present invention clearer and more concise. Make the inventive concept easier to understand. In practical application, more layers of air bubbles can be stratified through more layers of air separation channels 7, and more air separation channels 7 are arranged in any layer to make the oxygen flowing through the air separation channels 7 produce more finer bubble.

Further, as shown in FIG. 1 , the air bubbles formed by the upper and lower air separation channels 7 are respectively located near the bottle wall of the bottle body 3 and between the bottle wall and the oxygen inlet pipe 4 . In order to more effectively utilize the width of the distilled water in the bottle body 3 , in this embodiment, a gas distribution net 8 is also installed between the inner wall of the gas collecting tank 10 and the outer wall of the oxygen inlet pipe 4 and above the bearing 9 . Part of the oxygen entering the gas collection tank 10 through the oxygen inlet pipe 4 is formed by the gap between the oxygen inlet pipe 4 and the gas collection tank 10 after passing through the gap between the rolling elements on the bearing 9, and then cut by the gas distribution network 8. A plurality of small airflows are formed, thereby forming a plurality of small air bubbles, and the plurality of small air bubbles rise vertically or approximately vertically along the position close to the oxygen inlet pipe 4 . The bubble flow and the bubble flow generated by the air distribution channel 7 are naturally layered and do not interfere with each other, further making full use of the width of the bottle body 3 .
