Patent Description:
A ventilator is a necessary auxiliary device for maintaining respiration and ensuring ventilation of a respiratory failure patient, which conveys mixed air and oxygen to an airway of the patient during assisted respiration. Usually, oxygen provided by a wall-mounted oxygen setup or an oxygen cylinder is in a dry and cold state, so it is necessary to heat and humidify the mixed gas through a humidification tank to fully humidify a respiratory tract and protect trachea, bronchi and mucous membranes.

Referring to <FIG>, only two branch pipes <NUM> are connected to the joint pipe <NUM>, and the branch pipes <NUM> are located at the outlet end of the joint pipe <NUM>. The joint pipe <NUM> and the branch pipes <NUM> are substantially formed into the Y-shaped three-way pipe, and the two branch pipes <NUM> face each other to form an included angle, which can make the airflow be conveyed to both sides and reach more positions in comparison to that of only one joint pipe <NUM>. Certainly, in other embodiments, the joint pipe <NUM> may be connected to the branch pipe <NUM> at a position other than the outlet end, and the branch pipe <NUM> may extend obliquely upward or downward.

Further, the cavity is provided with a deflection plate <NUM> facing an outlet end of the branch pipe <NUM>, and the deflection plate <NUM> is configured to change a direction of gas flowing out of an outlet of the branch pipe <NUM>. The gas discharged from the branch pipe <NUM> may be blown into the deflection plate <NUM>, and the deflection plate <NUM> can guide to change an original direction of the airflow, so that the airflow can be dispersed into more directions, and can be further conveyed to more positions in the cavity, so that the airflow circulation in the cavity can be strengthened and dead zones can be avoided.

Ends of the two deflection plates <NUM> close to each other are spaced to form a flow channel. As shown in <FIG>, the deflection plates <NUM> are spaced to form the flow channel, which allows the airflows discharged from the two branch pipes <NUM> to pass through the flow channel.

Moreover, ends of the two deflection plates <NUM> far away from each other are both connected to the side wall <NUM> of the tank body <NUM>. The two deflection plates <NUM> and a part of the side wall <NUM> enclose a space provided with a channel outlet, and the airflow from the branch pipe <NUM> circulates in this space and is discharged from the channel.

The baffle <NUM> is recessed towards the exhaust pipe <NUM>. Both sides of the baffle <NUM> are inclined towards the exhaust pipe <NUM> relative to a middle portion to form a middle recess, and the baffle <NUM> and the flow guide plate <NUM> form the channel to allow the airflow to rise into the exhaust pipe <NUM>. Moreover, as shown in <FIG>, the baffle <NUM> may also be formed in a flat plate form.

Moreover, the outer circumferential surface of the joint pipe <NUM> is provided with a guide rib <NUM>, and the side wall <NUM> is provided with a guide groove <NUM> which can accommodate insertion of the guide rib <NUM>. A width of the guide rib <NUM> gradually increases along the length direction of the joint pipe <NUM>, allowing the guide rib <NUM> to be more easily inserted into the guide groove <NUM> on the hole wall of the side wall <NUM>. The cooperation of the guide rib <NUM> with the guide groove <NUM> may guide the insertion of the joint pipe <NUM> into the side wall <NUM>.

The air holes <NUM> may be arranged regularly or irregularly.

Moreover, the tank body <NUM> includes a hanging wall <NUM> with the joint pipe <NUM> extending horizontally and spaced from the hanging wall <NUM>. With reference to <FIG> and <FIG>, the joint pipe <NUM> is inserted into the cavity from a side portion of the tank body <NUM> (i.e., a side wall <NUM>) and extends substantially horizontally (when the tank body <NUM> is horizontally placed), with the hanging wall <NUM> of the tank body <NUM> being spaced from the part where the joint pipe <NUM> is inserted into the cavity to prevent the hanging wall <NUM> from blocking a part of the air holes <NUM> from discharging gas.

This causes the gas discharged from the joint pipe <NUM> to be discharged from the B side, and flows along a surface of the baffle <NUM> towards an edge of the cavity of the tank body <NUM>, and further flows along the edge of the cavity, so that the airflow can form a substantially spiral path, so as to flow to more positions in the cavity, avoid the existence of positions in the cavity where the gas cannot be blown, avoid airflow dead zones, improve a gas liquidity inside the cavity, prolong a gas flowing path, and thus improves a humidifying effect of the gas.

Further, a side edge of the baffle <NUM> on the B side is connected to a side wall <NUM> of the tank body <NUM>. With reference to <FIG>, <FIG>, and <FIG>, the side edge of the baffle <NUM> corresponding to the B side of the joint pipe <NUM> is connected to the side wall <NUM>, and the airflow flows along the baffle <NUM> towards the side wall <NUM>. When reaching a turning direction of the side wall <NUM>, the airflow flows along the side wall <NUM>, so that the airflow can pass through the edge of the cavity and reach a side of the baffle <NUM> facing away from the joint pipe <NUM>. A side edge of the baffle <NUM> located on the A side may be connected to the A side of the joint pipe <NUM> to block the airflow in the joint pipe <NUM> from being discharged from the A side.

As shown in <FIG>, a portion of the joint pipe <NUM> located on the A side is connected to the baffle <NUM>, and a portion of the joint pipe <NUM> located on the B side forms an opening to allow the airflow to flow out of the opening and flow along the surface of the baffle <NUM> toward the edge of the cavity.

The opening is formed on the B side of the outlet end of the joint pipe <NUM>. As shown in <FIG>, the outlet end of the joint pipe <NUM> is not flush, but is beveled, forming the opening on the B side, so that the airflow is deflected from the opening towards the B side.

According to another embodiment of the present solution, the outlet end of the joint pipe <NUM> is connected to an elbow <NUM> bent from the A side to the B side. As shown in <FIG>, the joint pipe <NUM> is connected to the elbow <NUM>, and the elbow <NUM> bends to the B side, which can also deflect the airflow to the B side and blow the airflow along the baffle <NUM> to the edge of the cavity, that is, to the side wall <NUM>.

A hanging wall <NUM> of the tank body <NUM> is connected to an exhaust pipe <NUM>, and the baffle <NUM> is located between the joint pipe <NUM> and an inlet end of the exhaust pipe <NUM>. Referring to <FIG>, <FIG> and <FIG>, a top portion of the tank body <NUM> is provided with the hanging wall <NUM>. As shown in <FIG>, the outlet end of the joint pipe <NUM> faces the inlet end of the exhaust pipe <NUM>, and the baffle <NUM> can block the airflow from the outlet end of the joint pipe <NUM> from directly reaching the inlet end of the exhaust pipe <NUM>. The baffle <NUM> changes a direction of the airflow from the outlet end of the joint pipe <NUM>, so that the airflow passes through other positions in the cavity before entering the inlet end of the exhaust pipe <NUM>. The exhaust pipe <NUM> may be integrally connected to the hanging wall <NUM> or may be detachably connected to the hanging wall <NUM>.

In addition, the baffle <NUM> is connected to the hanging wall <NUM> of the tank body <NUM> and spaced from a bottom wall <NUM> of the tank body <NUM>. The baffle <NUM> may prevent the gas exhausted from the joint pipe <NUM> be collected at the hanging wall <NUM>, and a lower end of the baffle <NUM> may be spaced from a bottom wall <NUM> of the tank body <NUM>, so that the airflow may also pass over a lower side of the baffle <NUM>, so that the airflow may be closer to the bottom wall <NUM> of the tank body <NUM>, i.e. closer to the water at a bottom portion of the tank body <NUM>, thereby achieving a humidifying effect on the airflow.

Moreover, one side edge of an inlet of the exhaust pipe 105close to the baffle <NUM> is connected to a flow guide plate <NUM>, the flow guide plate <NUM> is located between the baffle <NUM> and the inlet end of the exhaust pipe105, and a lower end of the flow guide plate <NUM> is inclined away from the baffle104. As shown in <FIG>, the inlet end of the exhaust pipe <NUM> is partially inserted into the cavity, the flow guide plate106 is connected to a partial edge of the exhaust pipe <NUM>, the lower end of the flow guide plate <NUM> is inclined towards the baffle <NUM>, and a channel smaller than an inner diameter of the exhaust pipe <NUM> is formed between the side wall <NUM> and the baffle <NUM>, so that the airflow flowing along the side wall <NUM> can enter the exhaust pipe <NUM> upwards, and the airflow can be prevented from directly entering the exhaust pipe <NUM> in a vertical upward direction, thus prolonging a path before the airflow enters the exhaust pipe <NUM> to a certain extent.

The joint pipe <NUM> passes through the side wall <NUM> of the tank body <NUM> and extends horizontally. As described above, the joint pipe <NUM> is horizontally inserted into the cavity of the tank body <NUM>. In other embodiments, the joint pipe <NUM> may also form a certain angle with a horizontal plane.

Moreover, the periphery of the joint pipe <NUM> is provided with a guide rib <NUM>, and the side wall <NUM> is provided with a guide groove <NUM> which can accommodate insertion of the guide rib <NUM>. As shown in <FIG> and <FIG>, a width of the guide rib <NUM> gradually increases along the length direction of the joint pipe <NUM>, allowing the guide rib <NUM> to be more easily inserted into the guide groove <NUM> on the hole wall of the side wall <NUM>. The cooperation of the guide rib <NUM> with the guide groove <NUM> may guide the insertion of the joint pipe <NUM> into the side wall <NUM>.

Moreover, an outer peripheral surface of the joint pipe <NUM> is provided with a buckle <NUM>, and the side wall <NUM> is provided with a clamping groove <NUM> which can be clamped and matched with the buckle <NUM>. As shown in <FIG> and <FIG>, the buckle <NUM> protrudes from the outer peripheral surface of the joint pipe <NUM>, and the clamping groove <NUM> is formed on a hole wall of the side wall <NUM> that accommodates the joint pipe <NUM> to pass through, and the buckle <NUM> may be inserted into the clamping groove <NUM> to achieve locking between the joint pipe <NUM> and the side wall <NUM>. The buckle <NUM> has an inclined surface gradually raised from one end to the other end to guide the buckle <NUM> to be inserted into the hole of the side wall <NUM>, and forms an end face perpendicular to a length direction of the joint pipe <NUM> at the other end so as to be clamped in the clamping groove <NUM>.
