A mask at the lower part of the nose-shaped bulge is provided with a guide tube with a valve, the guide tube with the valve is contained in the mouth of a patient, and the examination equipment is inserted into the stomach of the patient through the guide tube with the valve. The negative pressure suction access pipe is arranged at the lower position of the guide pipe with the valve and is connected with an external disinfection box through a hose. During examination, the expired air, droplets and secretions of the patient are sucked into the disinfection box through the negative pressure suction access pipe for disinfection treatment.

The top of the disinfection box is provided with an input port, the bottom of the disinfection box is provided with an output port, the input port is connected with a negative pressure suction access pipe through a hose, and the output port is connected with a negative pressure suction system through a pipeline. The inside of the disinfection box is divided into a disinfection liquid box and a filter box by a partition plate, the disinfection liquid box is communicated with the top of the filter box, the top of the disinfection liquid box is connected with an input port, the bottom of the disinfection liquid box is provided with a pressure release valve, and disinfection liquid is placed in the disinfection box. The filter box is filled with melt-blown cloth material. The pressure release valve and the bottom of the filter box are communicated with the output port. The gas and liquid secretion that patient expired in the operation under the effect of negative pressure suction system, flow into disinfectant box, liquid accumulation is in disinfectant box, and gaseous accessible rose box carries out filtration processing. When the liquid in the disinfectant tank reaches the set amount, the pressure release valve is automatically opened, and the liquid flows out and is discharged through the output port.

And the top of the disinfection box is provided with a medicine injection port with a sealing cover for injecting disinfectant or disinfection sheets. After filling, the container is covered by a sealing cover.

The edge of the face mask is provided with a circle of elastic rubber ring which can tightly cling to the face of a patient to prevent air leakage. The upper and lower positions of the face mask are provided with head fixing belts which are used for fixing the face mask on the face of a patient.

During gastroscopy, the patient wears the special face guard of airtight integral type gastroscopy, and direct gas and the secretion with patient's exhalation in the inspection are disinfected in attracting the access tube to attract it to the disinfect box through negative pressure on this face guard, avoid revealing in the inspection chamber, eliminate the risk of virus infection.

Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting of the invention.

Example (b): the special mask for the closed integrated gastroscope comprises a mask 1, wherein a nose-shaped bulge 11 is arranged on the mask 1, and an atomization/oxygen access pipe 2 is arranged on the nose-shaped bulge 11 and connected with atomization equipment or oxygen supply equipment as shown in figure 1. A mask at the lower part of the nose-shaped bulge 11 is provided with a conduit with a valve 3, a negative pressure suction access pipe 4 is arranged at the lower part of the conduit with the valve 3, and the negative pressure suction access pipe 4 is connected with an external disinfection box 5 through a hose. The catheter with the valve 3 is a section of catheter extending inwards, and the tail part of the catheter is provided with a valve 31. The examination device extends into the mouth of the patient through the conduit with the flap 3, and when the device is not inserted, the flap 31 seals the mouth of the tube to prevent the exhaled air of the patient from overflowing outwards. The upper and lower positions of the face mask are provided with head fixing belts 6 for fixing the face mask on the face of a patient when the face mask is worn. The edge of the face mask is provided with a circle of rubber ring 7 which can be tightly attached to the face of a patient after being worn, so that gas and liquid are prevented from leaking.

The sterilization chamber 5 is provided with an input port 51 at the top and an output port 52 at the bottom. The input port 51 is connected with the negative pressure suction access pipe 4 through a hose, and the output port 52 is connected with a negative pressure suction system of a hospital through a pipeline. The inside of the sterilizing box 5 is partitioned into a sterilizing liquid box 53 and a filtering box 54 by a partition plate, and the top parts of the sterilizing liquid box 53 and the filtering box 54 are communicated. The top of disinfectant tank 53 is connected with input port 51, and disinfectant tank 53 bottom is higher than disinfectant tank 5 bottoms, and disinfectant tank 53 bottom sets up a relief valve 55, places the antiseptic solution in the disinfectant tank, and patient's liquid secretion is followed the input port and is attracted by the negative pressure and flow into in disinfectant tank 53. The filter box 54 is filled with a meltblown material 8 for filtering gas. The relief valve 55 and the bottom of the filter tank 54 are both in communication with the output port 52. The bottom of the filter box 54 is provided with a baffle 59 with holes to support the packed meltblown material 8 and to allow air to pass smoothly.

The top of the disinfectant tank 53 is provided with a drug injection port 56 and a sealing cover 57, and disinfectant is injected through the drug injection port 56 and is covered by the sealing cover 57 after the injection is finished. The filter box 54 is open at the top and is sealed with a sealing plug 58. the internal meltblown material can be replaced by opening the sealing plug 58. The pressure relief valve 55 at the bottom of the disinfectant tank 53 can be a common air conditioner pressure relief valve, when the pressure value exceeds the design specification, the pressure or liquid is partially released to make the system work normally, when the liquid in the disinfectant tank 53 exceeds the set amount, the pressure relief valve 55 is automatically opened to discharge the liquid, the liquid is pumped out by the negative pressure suction system through the output port 52, and the pressure relief valve 55 can also be manually operated to discharge the liquid.

When the mask is worn for gastroscopy, the infection risk caused by the standard exceeding of the concentration of harmful aerosol in an inspection chamber due to the fact that a patient directly exposes gas and liquid secretion to the air through the mouth and the nose of the patient in the inspection can be avoided, meanwhile, the gas and liquid secretion are drained for disinfection treatment, and virus diffusion infection is avoided.

To sum up, the utility model discloses the embodiment of preferred, the all times according to the utility model discloses the change that technical scheme was done, the function effect of producing does not surpass the utility model discloses all belong to during technical scheme's the scope of protection.
