Example 1

The embodiment provides a surgical mask in combination with an attached drawing 1, which comprises a mask body 1, the edge of the mask body 1 is provided with a water collecting tank 2, and further comprises at least one water collecting pipe 3, the water collecting pipe 3 with the water collecting tank 2 is communicated and arranged, one end of the water collecting pipe 3 is connected with a valve body 4, a liquid flow channel is arranged in the valve body 4, a water inlet of the liquid flow channel is connected with the water collecting pipe 3, a plurality of water outlets are arranged on the liquid flow channel, a valve core is movably arranged in the liquid flow channel, a spring is arranged in one side of the valve core and the liquid flow channel, and the valve core is used for sealing a water inlet and a water outlet of the liquid flow channel.

The surgical mask of the embodiment is used for laughing gas surgery, and can only discharge water condensed on the inner wall of the mask body 1, but not discharge laughing gas at the same time.

In this embodiment, along with the respiration of the patient, the water drops will be gradually condensed on the cover body 1, the water flow formed by converging the water drops will be led into the water collecting tank 2 along the inner wall of the cover body 1, the water collecting tank 2 is connected with at least one water collecting pipe 3, and the end of the water collecting pipe 3 is connected with the valve body 4. After the water flow is led into the water collecting tank 2, the water flow can flow to the water collecting pipe 3 due to gravity, when the water in the water collecting pipe 3 is not much, the water flowing in through the water inlet of the liquid flow channel is not much, the valve core can not move, the valve body 4 is kept in a closed state, the operation can be normally performed at the moment, and the patient can not feel uncomfortable.

When the water in the water collecting pipe 3 increases to a threshold value, namely when the gravity of the water is larger than the elastic force of the spring, the valve core moves to the opening of the water outlet hole, at the moment, the valve body 4 is opened, and the water flow is discharged through the water outlet hole due to the gravity. In the water flow discharging process, laughing gas is always above water liquid due to low density, so that the laughing gas cannot be discharged.

When the water flow is discharged to a certain amount, the gravity of the water liquid is reduced, the pressure of the water flow received by the valve core is reduced, and after a certain threshold value is reached, the spring force is larger than the gravity of the water flow, and at the moment, the valve core is reset. During the closing of the valve body 4, the water flow is not completely discharged, and there is a certain surplus, so that laughing gas is not leaked into the air during the whole water flow discharging process.

Therefore, the surgical mask of the embodiment can discharge condensed water flow in the whole surgical process, so that a patient feels comfortable, laughing gas can not be discharged, and medical staff does not need to be exposed in the laughing gas environment.

As an alternative implementation of this embodiment, one end of the water collecting pipe 3 is connected to the lower position of the water collecting tank 2. This embodiment is a preferred arrangement of the water collection pipe 3, and in order to better meet the water discharge requirement, the end of the water collection pipe 3 is preferably arranged at the lowest position of the water collection tank 2. For example, when a general patient is kept lying flat during an operation, one end of the water collecting pipe 3 is positioned at the lowest position of the water collecting tank 2 when the cover 1 is used horizontally. If a plurality of water collecting pipes 3 are provided, they are distributed as needed in the lower position of the water collecting tank 2.

As an alternative implementation manner of the embodiment, the liquid flow channel is arranged perpendicular to the ground, the valve core is arranged perpendicular to the ground, the water inlet of the liquid flow channel is positioned at the highest position of the liquid flow channel, and the water outlet hole is positioned on the side wall of the liquid flow channel. In this embodiment, in a manner of setting the valve body 4, when the water collecting pipe 3 guides the liquid into the valve body 4, the valve body 4 naturally drops and keeps a vertical state due to the flexibility of the water collecting pipe 3. On the basis, the liquid flow channel is vertically arranged, the valve core is used for sealing a water inlet of the liquid flow channel at the top and a water outlet hole positioned on the side wall of the liquid flow channel, and the arrangement modes are more in accordance with the flow rule of the water liquid influenced by gravity and the working rule of the valve body 4.

As an alternative implementation of this embodiment, the edge of the cover 1 is curled to form the water collection tank 2. The embodiment is a setting mode of water catch bowl 2, and cover 1 edge is crooked, constitutes water catch bowl 2, and water catch bowl 2 and cover 1 integrated into one piece reduce the complexity of assembly processing, promotes production convenience.

As an alternative implementation manner of this embodiment, the cover 1 is provided with a first air inlet, one side of the first air inlet is provided with a second air inlet, and a throttle valve is arranged at the first air inlet. In this embodiment, the laughing gas is delivered through the first air inlet, and the oxygen is delivered through the second air inlet, and it is conceivable that the delivery of laughing gas may be controlled through the throttle valve at the first air inlet.

Example 2

With reference to fig. 1, this embodiment provides a surgical mask, which can be modified on the basis of embodiment 1 as follows: an air outlet is formed in the cover body 1, and a connecting pipe is communicated with the air outlet. In this embodiment, through setting up the gas outlet on the cover body 1 to the gas that the exhaust patient exhales, because when exhausting, the residual laughing gas in the face guard can exhale simultaneously, consequently need guide through the connecting pipe, avoid directly discharging to in the air, influence medical and nursing.

As an alternative implementation of this embodiment, the mask body 1 is a face mask or a nose mask.

As an alternative implementation of this embodiment, an elastic strap is provided on the outer side of the cover 1. The embodiment is a setting mode of the surgical mask, and the elastic binding band is arranged on the outer side of the mask body 1, so that the mask body 1 is more convenient to wear.

As an alternative implementation manner of this embodiment, the cover 1 is made of a silica gel material. The material of the cover body 1 is selected, and is generally preferably a non-toxic material of silica gel, so that the cover body has good plasticity and flexibility, and is suitable for being used as a material of the cover body 1 in the medical field.

As an alternative implementation manner of this embodiment, a hydrophobic layer is disposed on the inner wall of the cover body 1. In this embodiment, the inner wall of the housing 1 is coated with a hydrophobic layer so that the condensed water flow is easily guided from the hydrophobic layer into the water collection sump 2.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present utility model.
