Description

Technical Field

[0001] The utility model relates to the field of breathing tubes, in particular to a multifunctional breathing machine pipeline structure. Background Art

[0002] In clinical practice, patients experiencing breathing difficulties are assisted by a ventilator. The ventilator connects to the patient's endotracheal tube or breathing mask via a Y-connector, establishing a breathing passage. When the patient is breathing strongly on their own but has not yet reached the stage of extubation, the patient's exhaled air is typically discharged directly outward through the expiratory end of the Y-connector.

[0003] This exhalation discharge method has the following disadvantages: 1. The exhalation end is directly connected to the outside air, and the outside air can easily contaminate the exhalation end of the Y-shaped connector. Moreover, when the patient breathes, the outside air can be easily inhaled, causing the outside air to have adverse effects on the patient; 2. When the airflow exhaled by some patients carries infectious bacteria, it can easily cause disease transmission when it is directly discharged into the outside air. Therefore, it is necessary to optimize and improve it. Utility Model Content

[0034] like Figure 1-Figure 5 The piping structure of a multifunctional ventilator 1 shown includes: a Y-type connector 2, a one-way valve 6, an exhaust plug 8, a bacteria filter 11 and a drainage tube 12.

[0035] like Figure 1 As shown, the Y-type connector 2 includes an inhalation end, an exhalation end and a patient end. The inhalation end is provided with a first trachea 3, which is used to be connected to the ventilator 1. The patient end is provided with a second trachea 4, which is used to be connected to the patient's endotracheal tube 18 or breathing mask. The exhalation end is provided with a third trachea 5, which is used to discharge the patient's exhaled air to the outside.

[0036] like Figure 2As shown, the air inlet end of the one-way valve 6 is connected to the third air pipe 5, and the air outlet end of the one-way valve 6 is provided with a fourth air pipe 7; a T-shaped air flow channel is provided in the exhaust plug 8, and the T-shaped air flow channel includes a vertical first channel 9 and a horizontal second channel 10, the first channel 9 passes through the exhaust plug 8 in the up and down directions, and the second channel 10 is connected to the first channel 9, and the end of the fourth air pipe 7 away from the one-way valve 6 can be detachably inserted into the second channel 10; the bacteria filter 11 can be detachably provided at the upper end of the first channel 9; the drainage tube 12 can be detachably provided at the lower end of the first channel 9.

[0037] Specifically, this solution mainly adds a one-way exhalation line at the exhalation end of the Y-type connector 2 to ensure that the patient can exhale normally, but when the patient inhales, the outside gas cannot enter in the opposite direction, thereby not affecting the patient's normal use of the ventilator 1 for inhalation, and avoiding the contamination of the exhalation end of the Y-type connector 2 by outside air and the adverse effects of outside air on the patient.

[0038] Moreover, in view of the problem that when the air flow exhaled by some patients contains infectious bacteria, it is easy to cause disease transmission when it is directly discharged into the outside air. In this solution, a drainage tube 12 and a bacteria filter 11 are also provided at the exhaust plug 8. The drainage tube 12 is used to drain the condensed water condensed in the exhaust plug 8 when the patient exhales. Subsequently, a water collection bottle can be provided at the end of the drainage tube 12 away from the first channel 9 for unified collection and harmless treatment. The bacteria filter 11 can filter and intercept the bacteria in the patient's exhaled air to prevent the bacteria from spreading to the outside air.

[0039] In further settings, such as Figure 2 and Figure 4 As shown, an elastic valve flap membrane 13 is provided in the valve cavity of the one-way valve 6, one end of the valve flap membrane 13 is fixedly connected to the one-way valve 6, and the other end is a free end, and along the direction of airflow, the valve flap membrane 13 is inclined toward the center of the valve cavity. There are two valve flap membranes 13 and they are distributed one above and one below. The free ends of the upper and lower valve flap membranes 13 abut to cut off the valve cavity. Only when airflow flows in from the air inlet end of the one-way valve 6 can the airflow rush open the upper and lower valve flap membranes 13, making the valve cavity conductive, thereby realizing unidirectional conduction of the one-way valve 6.

[0040] The air inlet end of the one-way valve 6 is provided with a first annular groove 14, and the third air pipe 5 is detachably inserted in the first annular groove 14. The air outlet end of the one-way valve 6 is provided with a second annular groove 15, and the fourth air pipe 7 is detachably inserted in the second annular groove 15. Moreover, the circumferential groove surfaces of the first annular groove 14 and the second annular groove 15 are provided with anti-slip external threads to prevent the third air pipe 5 and the fourth air pipe 7 from being easily separated from the one-way valve 6.

[0041] like Figure 2 、 Figure 3 and Figure 5As shown, an annular limiting portion 16 is provided on the outer periphery of the drainage tube 12. When the drainage tube 12 is detachably inserted into the lower end of the first channel 9, the limiting portion 16 abuts against the outer wall of the exhaust plug 8, thereby preventing the drainage tube 12 from being over-inserted into the exhaust plug 8.

[0042] Furthermore, a guide hole 17 with a larger upper portion and a smaller lower portion is provided on the end portion of the drainage pipe 12 inserted into the first channel 9 . The guide hole 17 is in communication with the drainage pipe 12 , thereby facilitating the accumulation and discharge of condensed water into the drainage pipe 12 .

[0043] The bacteria filter 11 includes a shell, a filter element and a cannula 18. The interior of the shell is hollow. The cannula 18 is fixed at the bottom of the shell and connected to the shell.

The filter element is provided to filter bacteria. The airflow exhaled by the patient is filtered and then discharged from the exhaust port.

[0044] In summary, this solution has the following features:

[0045] 1. This solution mainly adds a one-way exhalation line at the exhalation end of the Y-shaped connector 2 to ensure that the patient can exhale normally, but when the patient inhales, the outside air cannot enter in the opposite direction, thereby not affecting the patient's normal use of the ventilator 1 to inhale, and avoiding the contamination of the exhalation end of the Y-shaped connector 2 by the outside air and the adverse effects of the outside air on the patient;

[0046] 2. In view of the problem that when the air flow exhaled by some patients carries infectious bacteria and is directly discharged into the outside air, it is easy to cause disease transmission, this solution also provides a drainage tube 12 and a bacteria filter 11 at the exhaust plug 8. The drainage tube 12 is used to drain the condensed water condensed in the exhaust plug 8 when the patient exhales. Subsequently, a water collection bottle can be provided at the end of the drainage tube 12 away from the first channel 9 for unified collection and harmless treatment, and the bacteria filter 11 can filter and intercept the bacteria in the patient's exhaled air to prevent the bacteria from spreading to the outside air.
