Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical supplies, especially to an oxygen inhalation device. BACKGROUND

[0002] In clinical work, field first aid and patient transfer, oxygen therapy is an indispensable part. Generally, oxygen inhalation devices are used to provide oxygen therapy for patients. The existing oxygen inhalation device includes an oxygen tank for oxygen supply and a humidification bottle for humidifying oxygen. After humidification, the oxygen is closer to the humidity of nature and is cleaner, which helps to moisturize the nasal cavity and alveoli and helps to reduce irritation to the respiratory tract. However, the existing oxygen inhalation device often has defects in some scenarios.

[0003] For example, in patient transfer or field first aid, jolting usually occurs, which causes the humidification bottle to tilt. Since the length of the wick in the humidification bottle is fixed and the position cannot be changed, the wick in the humidification bottle is not completely immersed in the humidification liquid, which causes the oxygen to be inhaled into the patient without humidification, resulting in a poor oxygen inhalation experience for the patient. In addition, due to the noise caused by bubble bursting during high-flow oxygen inhalation, patients who are sensitive to sound may be seriously affected in their rest. SUMMARY

[0004] The utility model aims to provide an oxygen inhalation device with stable and reliable oxygen humidification effect and reduced oxygen inhalation noise.

[0005] To achieve the above-mentioned purpose, the utility model provides an oxygen inhalation device, which comprises an oxygen input pipe for connecting an oxygen tank, a humidification bottle for humidifying oxygen, an oxygen output pipe for outputting oxygen, and a valve.

[0006] Compared with the prior art, the working principle of the oxygen inhalation device of the utility model is that oxygen enters the valve through the oxygen input pipe and then enters the hose of the humidification bottle. Since the hose is immersed in the humidification liquid, the oxygen that comes out of the hose contacts the humidification liquid to be humidified and then comes out of the oxygen output pipe. The oxygen inhalation device of the utility model has the end of the hose heavier than the front end of the hose, so that the end of the hose is continuously immersed in the humidification liquid under the action of gravity regardless of whether the humidification bottle is vertical or inclined, thereby avoiding the oxygen from being inhaled into the patient without humidification. In addition, the end of the hose is connected to the silencer, which can greatly reduce the sound of bubble bursting, thereby reducing the oxygen inhalation noise and ensuring the rest of the patient.

[0020] In order to illustrate the technical content, structural features, purposes and effects of the present application, the following will be described in detail in combination with the embodiments and the drawings.

[0021] Please refer to Figures 1 to 3The oxygen inhalation device 100 of the utility model includes oxygen input pipe 1 for connecting oxygen tank, humidification bottle 2 for humidifying oxygen, oxygen output pipe 3 for outputting oxygen and pass valve 4. One end of pass valve 4 is connected with oxygen input pipe 1, the other end of pass valve 4 is connected with humidification bottle 2, and oxygen output pipe 3 is connected on humidification bottle 2, and a hose 21 is arranged in humidification bottle 2. It can be understood that humidification bottle 2 is filled with humidification liquid. The end of the hose 21 is heavier than the front end of the hose 21. For example, the wall thickness of the hose 21 is sequentially increased from front to back, or the wall thickness of the end of the hose 21 is greater than the wall thickness of the front end of the hose 21, so that the end of the hose 21 is heavier than the front end of the hose 21, but it is not limited to this. The end of the hose 21 is connected to a silencer 5, and the silencer 5 has a plurality of small holes 51, which facilitates the discharge of humidified oxygen from the plurality of small holes 51.

[0022] Compared with the prior art, the working principle of the oxygen inhalation device 100 of the utility model is that oxygen enters pass valve 4 through oxygen input pipe 1 and enters the hose 21 of humidification bottle 2. Since the hose 21 is immersed in the humidification liquid, the oxygen that goes out of the hose 21 contacts the humidification liquid to be humidified and then goes out of the oxygen output pipe 3. The oxygen inhalation device 100 of the utility model is assisted by the end of the hose 21 being heavier than the front end of the hose 21, regardless of whether the humidification bottle 2 is vertical or inclined, the end of the hose 21 is continuously immersed in the humidification liquid under the action of gravity, thereby avoiding that the oxygen is inhaled by the patient without humidification. In addition, the end of the hose 21 is connected to the silencer 5, which can greatly reduce the sound of bubble burst, thereby reducing the oxygen inhalation noise and ensuring the rest of the patient.

[0023] Please refer to Figures 1 to 2 The humidification bottle 2 includes a bottle body 22, a bottle cap 23 and a liquid injection port cover 24.

More specifically, the oxygen output pipe 3 is connected to the bottle cap 23.

[0024] Please refer to Figures 1 to 2, preferably, the capacity of the humidification bottle 2 is 200-500ml. Specifically, in the embodiment, the capacity of the humidification bottle 2 is 300ml, which is large, so that the frequency of adding the humidification liquid by the nursing staff is reduced, and the workload of the nursing staff is reduced. Of course, in other embodiments, the capacity of the humidification bottle 2 can be 200ml, 400ml or 500ml, and is not limited thereto. In order to more clearly observe the capacity change of the humidification liquid, the bottle body 22 of the humidification bottle 2 is a transparent structure, and the side wall of the bottle body 22 is provided with a capacity scale mark.

[0025] For a long time, the patient continuously inhales oxygen, and due to environmental reasons, there are water condensation beads outside the humidification bottle 2, which drop onto the patient's clothes or bed sheet, seriously affecting the patient's comfort and increasing the patient's infection opportunity. To solve the above problems, please refer to Figure 1 and Figure 2 The oxygen inhalation device 100 further comprises a condensate collector 6 which is detachably sleeved outside the humidification bottle 2. With the help of the condensate collector 6, the condensed water dropped from the humidification bottle 2 can be collected, so that the condensed water dropped onto the patient's clothes or bed sheet is prevented, the patient's clothes or bed sheet is kept dry, and the infection is reduced. Preferably, the condensate collector 6 is a transparent structure, which is beneficial to the observation of the nursing staff on the collection of the condensed water. The condensate collector 6 is detachable, so that it can be removed according to the needs, cleaned after the condensed water is poured out, and then reinstalled outside the humidification bottle 2 after drying. Specifically, the condensate collector 6 is cup-shaped, the cup opening is arranged upward, and the cup opening is detachably connected with the bottle cap 23 of the humidification bottle 2.

[0026] During the process of moving or transferring the patient, the humidification liquid in the humidification bottle 2 may flow into the patient's nasal cavity due to the shaking and fluctuation, and the rising of the gas bubbles caused by the high flow oxygen inhalation, which may cause the patient to choke and cough. To solve the above problems, please refer to Figure 4 , and the connection between the oxygen output pipe 3 and the humidification bottle 2 is further provided with a defoamer 7 which is a mesh. With the help of the defoamer 7, it is ensured that the output oxygen can pass smoothly and the humidification liquid cannot pass, so that the patient is prevented from being choked into the nasal cavity by the humidification liquid, and the patient can safely inhale oxygen during the transfer and bumping process, high flow oxygen inhalation or outdoor lying in an uneven position, and can be smoothly rescued.
