The bottle head cover is connected to a bottle opening of the bottle body; an oxygen input connector, an oxygen output connector and a gas-guide tube are arranged on the bottle head, the lower end of the gas-guide tube extends into the bottle body, and the upper end of the gas-guide tube is connected with the oxygen input connector; the oxygen output connector is used for outputting oxygen output from the bottom end of the gas guide pipe; water is added into an inner-layer bottle of a bottle body, so that oxygen enters the inner-layer bottle of the bottle body through an oxygen input connector and an air guide pipe, and after the oxygen is humidified by the water in the inner-layer bottle, the humidified oxygen is output through an oxygen output connector; by means of the double-layer structure of the bottle body, when the temperature difference inside and outside the bottle body is large, the air layer in the sealed cavity formed between the outer-layer bottle and the inner-layer bottle can prevent the surface of the inner-layer bottle from making direct contact with outside air, and therefore the temperature reduction degree of the outer surface of the outer-layer bottle is reduced, and the condensation phenomenon is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an external oxygen humidifying bottle. Background Art

[0002] The main function of the oxygen humidifying bottle is to humidify the dry oxygen, moisten the oxygen, keep the patient's airway in a moist state, increase the patient's oxygen inhalation comfort, and prevent the irritation of pure oxygen gas to the mucosa; thus, it can moisten the alveoli, increase the alveolar activity, and is beneficial to gas exchange.

[0003] In the prior art, during the use of the oxygen humidifying bottle, condensation water forms and drips on the outer wall of the bottle body. The reason for this phenomenon is that the oxygen humidifying bottle is made of a single-layer material. When the low-temperature oxygen supplied by the hospital central oxygen supply system flows through the humidifying liquid, it will reduce the temperature of the humidifying bottle, resulting in the formation of condensation water on the surface of the humidifying bottle body. Especially in hot and humid weather conditions, the generation of condensation water will be more serious. The oxygen device of the central oxygen supply is mostly placed above the patient's head, and the condensation water will drip onto the patient's bed unit or even onto the patient's head, affecting the patient's comfort. During the oxygen humidifying process, a continuous gurgling sound is emitted, affecting the patient's rest; furthermore, it is usually necessary to wipe the humidifying bottle repeatedly many times, resulting in an increase in the workload of nurses; or it is necessary to wrap a cotton pad or put a plastic bag on the surface of the humidifying bottle, which not only affects the observation of the liquid level of the humidifying liquid but also affects the cleanliness and beauty of the ward.

[0004] The Chinese utility model patent document with the publication number CN216222588U discloses an oxygen humidifying bottle condensation water collection device, which includes a support plate, a water-absorbing sponge, a threaded through hole, a water storage bottle and other devices; in addition, the Chinese utility model patent document with the publication number CN213789468U discloses an oxygen humidifying bottle condensation water collection device, which includes a fixed clip, a rubber suction cup, a transparent observation window, an arc clip, a fixed column and other devices. Although the above types of oxygen humidifying bottles can solve the problem of condensation water dripping from the oxygen humidifying bottle, they cannot fundamentally solve the problem of condensation water generation; in addition, the condensation water collection devices such as the water storage bottle they set up will, on the basis of cleaning and disinfecting the oxygen humidifying bottle, lead to an increase in the clinical workload of cleaning and disinfecting the condensation water collection device; and lead to an increase in the working link of pouring out the condensation water; and, due to factors such as the water-absorbing sponge and rubber suction cup being prone to aging and the growth of bacteria and molds, it leads to an increase in the production and use cost and an increase in the risk of infection.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "assembly", "installation", "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] An externally mounted oxygen humidifying bottle provided by the utility model forms a bottle body with a double-layer structure by sleeving an inner bottle in an outer bottle. A bottle head with an oxygen input joint, an oxygen output joint and an air duct is covered and connected to the bottle body, and the air duct extends into the bottle body. During use, water is added to the inner bottle of the bottle body, so that oxygen enters the inner bottle of the bottle body through the oxygen input joint and the air duct. After the oxygen is humidified by water in the inner bottle, the humidified oxygen is output through the oxygen output joint. At the same time, due to the double-layer structure of the bottle body, when the temperature difference between the inside and outside of the bottle body is large, the air layer in the sealed cavity formed between the outer bottle and the inner bottle can prevent the surface of the inner bottle from directly contacting the external air, thereby reducing the degree of temperature reduction on the outer surface of the outer bottle and further reducing the occurrence of condensation.

[0033] Next, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.

[0034] Embodiment

[0035] Please refer to Figure 1 and Figure 2 An externally mounted oxygen humidifying bottle provided in this embodiment includes a bottle body 1 and a bottle head 2. The bottle body 1 is arranged in a double-layer structure including an inner bottle 110 and an outer bottle 120. The bottle head 2 is covered and connected to the bottle mouth of the bottle body 1. The bottle head 2 is provided with an oxygen input joint 210, an oxygen output joint 220 and an air duct 230. The lower end of the air duct 230 extends into the bottle body 1, and the upper end of the air duct 230 is connected to the oxygen input joint 210. The oxygen output joint 220 is used to output the oxygen output from the bottom end of the air duct 230.

[0036] In the externally mounted oxygen humidifying bottle of this embodiment, the outer bottle 120 is sleeved outside the inner bottle 110 to form a bottle body 1 with a double-layer structure. A sealed cavity is formed between the outer bottle 120 and the inner bottle 110, and air is provided in the sealed cavity to form an air layer in the sealed cavity. During use, water is added to the inner bottle 110 of the bottle body 1, so that oxygen enters the inner bottle 110 of the bottle body 1 through the oxygen input joint 210 and the air duct 230. After the oxygen is humidified by water in the inner bottle 110, the humidified oxygen is output through the oxygen output joint 220.

[0037] The principle of the external oxygen humidifying bottle in this embodiment to avoid the generation of condensed water is as follows: When there is a large temperature difference between the inside and outside of the bottle body 1, if the temperature of the outer surface of the single-layer bottle body in the prior art is lower than the dew point temperature of gas liquefaction, condensed water will be generated. Since air is a heat conductor with poor heat conduction performance, the external oxygen humidifying bottle in this embodiment enables the air layer in the sealed cavity formed between the outer layer bottle 120 and the inner layer bottle 110 to prevent the surface of the inner layer bottle 110 from directly contacting the external air, thereby reducing the degree of temperature drop on the outer surface of the outer layer bottle 120, and further reducing the occurrence of the condensation phenomenon. At the same time, the principle of sound insulation and noise reduction of the external oxygen humidifying bottle in this embodiment is as follows: The above-mentioned air layer can absorb and reduce the propagation of sound waves. Compared with the single-layer bottle body in the prior art, the double-layer structure of the bottle body 1 of the external oxygen humidifying bottle in this embodiment can better isolate the internal noise and achieve the effect of reducing noise.

[0038] As Figure 1 shown, in some embodiments, a flow tube 240 for displaying the oxygen output speed is provided above the bottle head 2. A floating ball 250 is arranged inside the flow tube. The position of the floating ball 250 in the flow tube 240 can facilitate the understanding of the oxygen quantity in the bottle body 1, or the change in the position of the floating ball 250 in the flow tube 240 can facilitate the understanding of the oxygen input quantity entering the bottle body 1.

[0039] In some embodiments, a transparent outer cover 260 is sleeved outside the flow tube 240. The transparent outer cover 260 can protect the flow tube 240 and at the same time ensure the observation of the position of the floating ball 250 in the flow tube 240.

[0040] In some embodiments, an adjustment knob 270 is provided on the side wall of the bottle head 2 for adjusting the oxygen output speed.

[0041] In some embodiments, a gas filter block 280 is provided at the bottom of the air guide tube 230 for filtering the input oxygen.

[0042] Specifically, a safety valve 221 is provided on the oxygen output joint 220 for releasing pressure. When the oxygen tube is bent and the ventilation is blocked, the gas leaks from the safety valve 221 to protect the flow tube 240.

[0043] External threads 101 are provided on the outer wall of the bottle mouth of the bottle body 1. The bottle head 2 is set to be cylindrical, and internal threads are provided on the inner wall. The bottle head 2 is connected to the bottle mouth of the bottle body 1 by screwing on.

[0044] It should be noted that the bottle head 2 can adopt existing technology products, which can be equipped with an oxygen input connector 210, an oxygen output connector 220 and an air guide tube 230, as well as a flow tube 240, a float 250, a transparent outer cover 260, an adjustment knob 270, a gas filter block 280, a safety valve 221 and an internal thread.

[0045] Please refer to Figure 1 and Figure 2 In some embodiments, the inner bottle 110 and the outer bottle 120 are both transparent bottles, the inner bottle 110 and the outer bottle 120 are connected at the bottle mouth, and a gap is provided between the bottle wall of the inner bottle 110 and the bottle wall of the outer bottle 120; thereby, it is convenient to observe the situation in the bottle body 1 through the transparent inner bottle 110 and the outer bottle 120; and it is convenient to form an air layer-type sealed cavity between the inner bottle 110 and the outer bottle 120 through the connection at the bottle mouth and the gap between the two.

[0046] like Figure 2 As shown, in some embodiments, the bottle body of the inner bottle 110 or the outer bottle 120 is provided with a capacity scale line 130 to facilitate observation of the amount of water in the bottle body 1 .

[0047] In some embodiments, the minimum value of the capacity scale line 130 is the minimum capacity of water injected into the bottle body 1; the maximum value of the capacity scale line 130 is the maximum capacity of water injected into the bottle body 1; thereby facilitating the control of the amount of water injected into the bottle body 1.

[0048] like Figure 2 As shown, max represents the maximum value scale line of the capacity scale line 130, and min represents the minimum value scale line of the capacity scale line 130. It should be noted that the minimum value of the capacity scale line 130 should generally be greater than 0, that is, the amount of water injected into the bottle body 1 should be greater than 0, and the minimum value scale line of the capacity scale line 130 is above the bottom of the bottle body 1.

[0049] In the external oxygen humidification bottle of this embodiment, the bottle body 1 is set to be cylindrical. The inner bottle 110 and the outer bottle 120 are both set to be cylindrical, and the two can be set to be an integrally formed structure connected at the bottle mouth. The outer diameter of the inner bottle 110 is smaller than the inner diameter of the outer bottle 120. The bottom surface of the inner bottle 110 is arranged above the bottom surface of the outer bottle 120, so that the outside of the inner bottle 110 is fully provided with a sealed cavity containing an air layer. The central axis of the inner bottle 110 and the outer bottle 120 coincide to ensure the balance stability of the bottle body 1. The bottle body 1 is set to be a PVC bottle, that is, the inner bottle 110 and the outer bottle 120 are both set to be PVC bottles.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
