Description

Technical Field

[0001] The invention belongs to the technical field of secretion cleaning, and in particular relates to a respiratory secretion cleaning device. Background Art

[0002] Respiratory secretions generally refer to exudates caused by inflammation, also known as sputum. The accumulation of sputum in the respiratory tract can easily cause patients to have difficulty breathing, so it needs to be cleaned.

[0003] At present, the Chinese invention with the publication number CN106075613B discloses an automatic respiratory tract sputum cleaning device, which generally adopts a sputum suction device, which inserts a hose into the respiratory tract and uses the negative pressure suction generated by the sputum suction pump to suck the secretions into a container. However, the existing sputum suction device needs to insert the hose into the respiratory tract, which will affect the normal breathing of the patient, causing the patient to have difficulty breathing, and easily cause a large negative pressure to be generated inside the respiratory tract. If the patient cannot breathe effectively, the negative pressure cannot be balanced in time, so the tissue inside the respiratory tract will shrink and squeeze together, affecting the medical staff to perform sputum suction operations. At the same time, after the sputum secretions are sucked into the hose, since the hose needs to be bent to be inserted into the respiratory tract, the sputum secretions are very easy to accumulate at the bend of the hose, causing the hose to be blocked. At this time, either the hose is pulled out for silting, or the suction of the sputum suction pump is increased to forcibly suck out the sputum. However, both methods have certain limitations. After pulling out the hose to clear the silt, the hose needs to be reinserted, which affects efficiency and increases the patient's pain. When the suction force of the suction pump is increased, medical staff generally cannot immediately reduce the suction force of the suction pump at the moment the sputum is sucked out. The suction tube will generate huge suction on the inside of the respiratory tract, which can easily damage the respiratory tract and has low safety. Summary of the invention

[0004] The purpose of the present invention is to provide a respiratory secretion cleaning device, which has the advantages of being able to replenish air and balance the internal air pressure when the patient has difficulty breathing during the respiratory secretion cleaning process, and facilitating the auxiliary operation of pushing the blocked sputum secretions out of the hose, thereby improving the efficiency of respiratory secretion cleaning.

The friction force when the sputum container 2 is connected to the top of the outer shell 1 is increased, and the stability of placement is improved.

[0034] refer to Figure 4 , Figure 5 The top of the sealing cover 4 is threadedly connected with a threaded cover plate 15 used in conjunction with the sterilizing filter element 805. The top of the sealing cover 4 can be opened, thereby being convenient to replacing the sterilizing filter element 805 to ensure the sterilizing filtration effect of the air.

[0035] refer to Figure 6 , Figure 7 The bottom of the metal plug 806 is welded with an arc-shaped end 16 used in conjunction with the air-infusing hole 809. It is convenient to insert the sputum suction hose 7 into the patient's respiratory tract, and at the same time, sputum secretions can be prevented from blocking the air-infusing hole 809.

[0036] Brief description of the usage process: When it is necessary to clean the respiratory secretions; first, thread the sealing cover 4 onto the top of the sputum container 2, and thread the suction hose 7 to one side of the sealing cover 4, while the air outlet line 6 is threaded to the other side of the sealing cover 4. At the same time, the suction line 5 and the air outlet line 6 are fixedly connected to the output end and the input end of the suction pump 3, respectively. Then use the metal plug 806 to insert the suction hose 7 into the patient's respiratory tract. At this time, turn on the suction pump 3, and the sputum container 2 can form a negative pressure inside through the air outlet line 6 and the suction chamber 802, so that suction is generated at the end of the suction hose 7 inserted into the respiratory tract, and the sputum secretions are sucked out into the sputum container 2 through the suction groove 807, and the air is discharged outward through the suction line 5, thereby completing the cleaning of the respiratory secretions; When the air pressure inside the respiratory tract needs to be balanced during the process of cleaning the respiratory tract secretions: first, connect the end of the suction line 5 away from the suction pump 3 with the internal thread of the sealing cover 4, then turn on the suction pump 3 to drive the air outlet line 6 to form a negative pressure, and the suction hose 7 sucks the sputum secretions inside the respiratory tract into the sputum container 2, and the air inhaled from the respiratory tract can flow back into the return air cavity 804 through the suction line 5, and pass through the disinfection filter element 805 for sterilization and filtration. Then, the air is transported through the air replenishment hose 803, so that after passing through the connecting hole 808, the air is discharged into the respiratory tract again from the air replenishment hole 809, and a cycle of suction hose 7 suctioning sputum and air replenishment hose 803 is formed, thereby balancing the air pressure inside the respiratory tract and preventing the respiratory tract tissue from shrinking and squeezing; When the suction sputum pipe is blocked by sputum secretions and needs to be unblocked during the process of cleaning respiratory secretions, first, by rotating the pull bolt 910 and engaging the threaded tube 909, the connecting guide wire 901 is pulled to slide outward, so that the connecting guide wire 901 drives the sealing plug 908 to slide downward, and the bottom of the connecting hole groove 808 is blocked by the tapered inclined groove 907, so that air cannot pass through the connecting hole groove 808. At the same time, the connecting guide wire 901 drives the connecting slide bar 903 to slide downward inside the slide groove 902, so that the sliding sleeve 904 slides out of the metal plug 806. Then the sliding sleeve 904 can seal the suction sputum groove 807. Since the inner surface of the sliding sleeve 904 is provided with an air guide inclined groove 905, when the air cannot be discharged through the connecting hole groove 808, it will flow downward through the gap formed by the upward movement of the air guide inclined groove 905 and the metal plug 806. The sputum suction groove 807 is sealed by the sliding sleeve 904, and the air cannot flow outward, so it can only flow into the inside of the sputum suction hose 7, generating thrust on the sputum secretions blocked in the sputum suction hose 7, thereby pushing the sputum secretions into the sputum container 2. At the same time, after the pull bolt 910 is rotated in the reverse direction, the sliding sleeve 904 and the sealing plug 908 can be reset by the elastic force of the reset spring 906, and then the cleaning process of suctioning sputum and replenishing air is carried out again.
