[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 3 , the utility model provides the following technical solutions: a child anesthesia inhalation induction device, comprising a nebulizer 1, an air supply hose 2 and an atomizing mask 3, the atomizing mask 3 is connected to the nebulizer 1 by the air supply hose 2, and also comprises an air inlet check valve 4, an air outlet check valve 5 and a balloon 6;

[0025] Depend on Figure 1 and Figure 2 As shown, in this embodiment, an air inlet nozzle 31 and a No. 1 air outlet nozzle 32 are fixed on the atomizing mask 3, the air supply hose 2 is connected to the air inlet nozzle 31 by means of an air inlet check valve 4, and the balloon 6 is connected to the No. 1 air outlet nozzle 32 by means of an air outlet check valve 5. Therefore, when in use, the atomizing mask 3 is worn on the face of the child and covers the mouth and nose of the child, and anesthetic gas is generated by the atomizer 1. The anesthetic gas passes through the air supply hose 2, the air inlet check valve 4 and the air inlet nozzle 31 in sequence and enters the atomizing mask 3 and is inhaled by the child. Due to the arrangement of the No. 1 air outlet nozzle 32, the air outlet check valve 5 and the balloon 6, excess anesthetic gas and gas exhaled by the child will pass through the No. 1 air outlet nozzle 32 and the air outlet check valve 5 and be temporarily stored in the balloon 6. The air outlet check valve 5 prevents gas backflow, which, on the one hand, prevents overflow of excessive anesthetic gas and prevents medical staff from accidentally inhaling it. On the other hand, after the gas enters the balloon 6, it will gradually expand, thereby strengthening the child's willingness to breathe independently and facilitating the child to quickly enter an anesthetized state.

[0026] It should be noted that the nebulizer 1 is a very common medical device, and its internal structure and working principle are already disclosed in the prior art, which will not be described in detail here.

[0027] Depend on Figure 1 and Figure 2 As shown, as an optional embodiment, this embodiment also includes a syringe 7, and a No. 2 air outlet nozzle 33 is fixed on the nebulizer mask 3. The syringe 7 is connected to the No. 2 air outlet nozzle 33. When the nebulizer mask 3 needs to be disassembled in the later stage, because there may be residual anesthetic gas and gas exhaled by the child in the nebulizer mask 3, it is safer to extract the gas in the nebulizer mask 3 through the syringe 7 before disassembling the nebulizer mask 3, so as to avoid the residual gas from being accidentally inhaled by medical staff.

[0028] Depend on Figure 1 and Figure 3 As shown, as an optional embodiment, this embodiment further includes a hanging mechanism 8, and the nebulizer 1 is hung on the bed using the hanging mechanism 8. When in use, the nebulizer 1 is first hung on the bed using the hanging mechanism 8.

[0029] Depend on Figure 1 and Figure 3 As shown, as an optional embodiment, in this embodiment, the suspension mechanism 8 includes an inverted L-shaped fixed splint 81, an L-shaped movable splint 82, a fixed plate 83 and an adjusting screw 84. The inverted L-shaped fixed splint 81 is fixed to the back of the nebulizer 1, the L-shaped movable splint 82 is arranged opposite to the inverted L-shaped fixed splint 81, the fixed plate 83 is fixed to the back of the nebulizer 1, the adjusting screw 84 is installed on the fixed plate 83 by threaded engagement, and the top of the adjusting screw 84 is rotatably connected to the L-shaped movable splint 82 by a bearing. The nebulizer 1 is hung by cooperating with the inverted L-shaped fixed splint 81 and the L-shaped movable splint 82. By rotating the adjusting screw 84, the adjusting screw 84 drives the L-shaped movable splint 82 to move under the action of threaded engagement. On the one hand, the bed can be clamped to ensure the stability of the suspension of the nebulizer 1. On the other hand, the initial interval between the L-shaped movable splint 82 and the inverted L-shaped fixed splint 81 can be adjusted to adapt to different beds.

[0030] Depend on Figure 1 and Figure 3 As shown, as an optional embodiment, in this embodiment, a knob 85 is fixed at the bottom end of the adjusting screw 84 , and the adjusting screw 84 can be easily rotated by the knob 85 .

[0031] Depend on Figure 1 and Figure 3 As shown, as an optional embodiment, in this embodiment, a guide column 86 is fixed on the bottom surface of the L-shaped movable splint 82 and is arranged to pass through the fixed plate 83, which is used to guide and support the L-shaped movable splint 82 and improve the stability of the L-shaped movable splint 82.

[0032] Depend on Figure 1 and Figure 3 As shown, as an optional embodiment, in this embodiment, a rubber anti-skid lining 87 is bonded and fixed to the inner walls of the inverted L-shaped fixed splint 81 and the L-shaped movable splint 82. After the L-shaped movable splint 82 and the inverted L-shaped fixed splint 81 clamp the bed, the rubber anti-skid lining 87 shrinks to produce an anti-skid effect, further improving the suspension stability of the nebulizer 1 and avoiding accidental slipping of the nebulizer 1.

[0033] Working principle and use process of the utility model: When using the pediatric anesthesia inhalation induction device of the utility model, the nebulizer 1 is firstly hung on the bed by the hanging mechanism 8, and the adjusting screw 84 is rotated to drive the L-shaped movable clamping plate 82 to move under the action of the screw thread, and the bed is clamped by the L-shaped movable clamping plate 82 and the reverse L-shaped fixed clamping plate 81;

[0034] The atomizing mask 3 is worn on the face of the child and covers the child's mouth and nose. The atomizer 1 generates anesthetic gas, which passes through the gas supply hose 2, the gas inlet check valve 4 and the gas inlet nozzle 31 in sequence and enters the atomizing mask 3 to be inhaled by the child.

[0035] With the arrangement of the No. 1 gas outlet nozzle 32, the gas outlet one-way valve 5 and the balloon 6, the excess anesthetic gas and the gas exhaled by the patient will pass through the No. 1 gas outlet nozzle 32 and the gas outlet one-way valve 5 and be temporarily stored in the balloon 6. The gas outlet one-way valve 5 prevents gas backflow, which, on the one hand, prevents the overflow of excessive anesthetic gas and prevents medical staff from accidentally inhaling it. On the other hand, the balloon 6 will gradually expand after the gas enters, which strengthens the patient's willingness to breathe autonomously and facilitates the patient to quickly enter the anesthesia state.

[0036] When the atomizing mask 3 needs to be disassembled at a later stage, the gas in the atomizing mask 3 is first extracted through the syringe 7 before disassembling the atomizing mask 3, which is safer and avoids the residual gas from being accidentally inhaled by medical staff.

[0037] It should be noted that the atomizer 1, the air inlet check valve 4 and the air outlet check valve 5 are all conventional commercially available equipment, and technicians in this field can make conventional selections according to usage requirements. Their working principles are common knowledge known to technicians in this field and have been fully disclosed in the prior art, so they will not be elaborated in this article.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
