Description

Technical Field

[0001] The present application relates to the field of humidification bottles, and in particular to a medical humidification bottle. Background Art

[0002] As a medical device, a medical humidifier bottle is used to provide oxygen to patients. The medical humidifier bottle generally includes a bottle body and a bottle cap that can be covered with the bottle body. An air inlet nozzle is arranged in the middle of the bottle cap, and an air outlet nozzle is arranged on the side of the air inlet on the bottle cap. When in use, a certain amount of liquid will be contained in the bottle body. After the oxygen enters through the air inlet nozzle, it passes through the filter tube connected to the air inlet nozzle, passes through the liquid, and then outputs the oxygen from the air outlet nozzle for the patient to use.

[0003] However, the inventor discovered that during the use of the medical humidification bottle, a large number of bubbles will be generated after the gas reaches the liquid through the filter tube. After the bubbles rise to the surface of the liquid, they will continue to rise until they reach the inner side of the bottle cap, and even bubbles may enter the outlet nozzle, which will pose a certain hidden danger to the patient's normal oxygen supply.

[0025] The following is combined with Figures 1 to 7 This application is described in further detail.

[0026] The embodiment of the present application discloses a medical humidification bottle, comprising a bottle body 1, a bottle cap 2 that can be covered with the bottle body 1, an air inlet nozzle 3 is arranged in the middle of the bottle cap 2, an air outlet nozzle 4 is arranged on the bottle cap 2 on one side of the air inlet, and an annular enclosure 5 is arranged in the middle of the bottom end of the bottle body 1.

[0027] Example 1

[0028] Reference Figure 1 An air intake filter connected to the air intake nozzle 3 is arranged in the bottle body 1, and the air intake filter includes a first air intake pipe 6 and a filter core 7 with an opening at one end. The top end of the first air intake pipe 6 is connected to the inner end of the air intake nozzle 3. The connection method can be that the top end of the first air intake pipe 6 is inserted into the inner end of the air intake nozzle 3, the filter core 7 is installed at the bottom end of the first air intake pipe 6, and the lower end of the filter core 7 is located in the area enclosed by the enclosure 5.

[0029] Usually, since a certain amount of liquid is contained in the bottle during use, a large number of bubbles generated in the liquid will accumulate and rise on the surface of the liquid. In order to prevent the bubbles from overflowing from the air outlet 4 and causing safety hazards, refer to Figure 2 In this embodiment, an anti-overflow vent cover 8 is installed in the middle of the end surface of the bottle cap 2 facing the bottle body 1. The anti-overflow vent cover 8 has a bowl-shaped structure. A mounting hole for an air intake filter to pass through is provided in the middle of the anti-overflow vent cover 8. A plurality of first vent holes 9 are provided along the circumference of the anti-overflow vent cover 8. At the same time, in order to better prevent bubbles from entering the air outlet nozzle 4, the projection of the anti-overflow vent cover 8 relative to the bottle cap 2 can cover the air inlet nozzle 3 and the air outlet nozzle 4.

[0030] In order to facilitate the installation of the anti-overflow vent cap 8, the inner end of the air inlet nozzle 3 can be protruded relative to the inner side of the bottle cap 2, and the anti-overflow vent cap 8 is provided with a mounting tube 10 at the mounting hole, and the mounting tube 10 is installed at the inner end of the air inlet nozzle 3.

[0031] Example 2

[0032] Reference Figure 3 , 4An air intake filter silent part is arranged in the bottle body 1, and the air intake filter silent part comprises a second air intake pipe 11 and a columnar water absorption rod 12. The water absorption rod 12 absorbs water above the liquid surface by adopting the microporous physical water absorption principle. Part of the dry oxygen air flow is blown out from the tiny micropores of the wet water absorption rod, and part of the air flow takes away the moisture on the surface to achieve the purpose of humidifying the oxygen. The top end of the second air intake pipe 11 is connected with the inner end of the air intake nozzle 3, and the water absorption rod 12 is installed inside the second air intake pipe 11. In order to better achieve the effect of silent ventilation, a plurality of second air holes 13 are arranged on the tube wall of the second air intake pipe 11, and the second air holes 13 can be arranged in multiple groups along the axial direction of the second air intake pipe 11.

[0033] Example 3

[0034] Reference Figure 5 A protective cover 14 is installed on the bottle cap 2. The protective cover 14 can be covered on the bottle cap 2 during transportation, so as to protect the air inlet nozzle 3 and the air outlet nozzle 4 of the product from being damaged. The protective cover 14 in this embodiment can be applied to the products in Examples 1 and 2. When the protective cover 14 is in use, the protective cover 14 can also be removed and mounted on the bottom of the bottle body 1, and can be used as a container for condensed water on the surface of the bottle body 1 when it slides down.

[0035] Example 4

[0036] Reference Figure 6 The difference from Example 3 is that a protective cap 15 is installed on the bottle cap 2 and is sleeved on the air inlet nozzle 3 and the air outlet nozzle 4, and the protective cap 15 can also protect the air inlet nozzle 3 and the air outlet nozzle 4 of this product from being damaged. In this embodiment, the protective caps 15 on the air inlet nozzle 3 and the air outlet nozzle 4 are of an integrated design, but of course they can also be of a split design.

[0037] Example 5

[0038] Reference Figure 7 In this embodiment, an arc-shaped anti-overflow sheet 16 is provided on the inner side of the bottle cap 2 at the air outlet 4. The anti-overflow sheet 16 is provided on the side close to the outer edge of the bottle cap 2. The design of the anti-overflow sheet 16 can achieve the effect of bubbles overflowing from the water outlet 4. The anti-overflow sheet 16 and the anti-overflow vent cover 8 in Example 1 or the air intake filter silent part in Example 2 can better prevent the bubble from overflowing.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
