Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4, including oval-shaped shell 1, axial through-hole 2 about the left and right sides of lateral wall has been seted up respectively on shell 1, the coaxial screwed pipe 3 that is equipped with in the through-hole 2 on right side, the screwed pipe 3 upper end stretches out through-hole 2 and threaded connection has collection bottle 4 that the opening is down, set up a plurality of ventholes 5 that link up from top to bottom along its circumferencial direction equipartition on the lateral wall under collection bottle 4, the coaxial cartridge filter 6 that is equipped with in the left through-hole 2, all be equipped with filter pulp 7 in cartridge filter 6 and a plurality of venthole 5, axial hose 8 about lateral wall rear end is equipped with on shell 1, be equipped with three-way pipe 9 in the shell 1, three free end of three-way pipe 9 is connected with two through-holes 2 and hose 8 respectively.

The diameter of the flexible tube 8 is larger than that of the tracheal tube in order to fix the device on the tracheal tube.

In order to facilitate the disassembly of the collecting bottle 4, a plurality of anti-slip strips 10 which are uniformly distributed along the circumferential direction are arranged on the outer edge surface of the collecting bottle 4 in the vertical direction.

In order to fix the tracheal cannula conveniently, the front end of the hose 8 is provided with a through groove 11, and the upper end of the hose 8 extends out of the shell 1 and is provided with a binding belt 12.

In order to prevent the patient from sucking out the sputum of the collecting bottle 4, the right end of the three-way pipe 9 is provided with a liquid discharge one-way valve 13 with an opening far away from the three-way pipe 9.

In order to prevent the sputum from entering the filter cylinder 6, the left end of the three-way pipe 9 is provided with an air inlet one-way valve 14 with an opening facing the three-way pipe 9.

When the utility model is used, the free end of the tracheal cannula on the body of a patient is inserted into the hose 8, then the ribbon 12 is tensioned, and the inner surface of the hose 8 is contacted with the outer surface of the tracheal cannula after the ribbon 12 is tensioned because the hose 8 is provided with the through groove 11, so the device is fixed on the tracheal hose 8;

when a patient inhales, the liquid drainage one-way valve 13 is closed, the air inlet one-way valve 14 is opened, outside air enters the three-way pipe 9 through the filter cotton 7 in the filter cylinder 6, the filter cotton 7 effectively filters the air entering the three-way pipe 9, the respiratory tract of the patient is protected, the risk of lower respiratory tract infection of the patient is reduced, the filtered air enters the patient body through the hose 8, when sputum of the patient is sprayed out of the tracheal cannula, the air inlet one-way valve 14 is closed, the liquid drainage one-way valve 13 is opened, the sputum enters the three-way pipe 9 through the hose 8 and then enters the collection bottle 4 through the threaded pipe 3;

when a patient exhales, the liquid discharge one-way valve 13 is closed, the air inlet one-way valve 14 is opened, the gas exhaled by the patient enters the three-way pipe 9 through the hose 8, then enters the collecting bottle 4 through the threaded pipe 3, and is finally filtered and discharged into the outside air through the filter cotton 7 in the air outlet 5, so that germs in the patient are prevented from being discharged into the outside air, and the cross infection between the patient and the family members is effectively avoided;

when the sputum in the receiving flask 4 was too much, medical personnel accessible a plurality of antislip strips 10 anticlockwise rotation receiving flask 4 twisted off receiving flask 4 from screwed pipe 3, handled the sputum in the receiving flask 4 after, fixed receiving flask 4 on screwed pipe 3 again can.
