Abstract
Description
Technical Field
[0001] This application relates to the technical field of respiratory equipment, and particularly to a respiratory connection pipeline and its condensate drainage device. Background Art
[0002] Clinically, critically ill patients in the ICU rely on ventilators for assisted ventilation. Since ventilators have a heating and humidifying function, condensate often appears in the respiratory pipelines of ventilators. The respiratory pipeline is connected to the patient's tracheal intubation through a rotatable respiratory circuit. Affected by factors such as body position, condensate accumulates at one end of the respiratory circuit close to the connection with the respiratory pipeline. During the operation of suctioning the patient or other situations that change the patient's body position, the accumulated condensate is likely to flow back into the tracheal intubation through the respiratory circuit, which can easily cause choking in the patient and increase the probability of lung infection.
[0003] To avoid the harm caused to the patient by the operation, it can be prompted by the ventilator alarm or actively observed by medical staff to timely handle the condensate, such as opening the connection port between the respiratory pipeline and the breathing tube to drain the water. When the connection port of the existing respiratory circuit is opened, the drained condensate will splash everywhere, and there is a risk that the connection port of the respiratory circuit will be exposed, which is prone to bacteria growth and there are issues related to infection control. At the same time, disconnecting the connection port of the respiratory circuit affects the ventilator's assistance to the patient in ventilation. Frequent disconnection and reconnection may cause the connection port to become loose and there is a risk of tube detachment. Summary of the Utility Model

[0023] Embodiment 1:
[0024] As Figure 1As shown in the figure, an embodiment of the present application provides a condensate drainage device for a breathing connection pipeline, including a connection channel 10, a water collection cup 20, and a drainage pipeline 30. A first connection port 11, a second connection port 12, and a third connection port 13 are provided on the connection channel 10. The third connection port 13 is connected to the water inlet of the water collection cup 20, the water outlet of the water collection cup 20 is connected to the drainage pipeline 30, a first switch 40 is provided between the third connection port 13 and the water inlet of the water collection cup 20, and a second switch 50 for draining the water in the water collection cup 20 is provided on the drainage pipeline 30.
[0025] It should be noted that, as Figure 2 shown, the first connection port 11 is used to connect with the breathing pipeline 60 of the ventilator, and the second connection port 12 is used to connect with the trachea 70. Or the first connection port 11 is used to connect with the trachea, and the second connection port 12 is used to connect with the breathing pipeline of the ventilator. Among them, when the water collection cup 20 is not draining water, the first switch 40 is always in the open state, and the second switch 50 is always in the closed state, so that the connection channel between the connection channel 10 and the water collection cup 20 is unblocked, allowing the condensate water on the breathing pipeline 60 and the trachea 70 to flow into the water collection cup 20 from the third connection port 13. During the drainage process of the water in the water collection cup 20, the first switch 40 is in the closed state, so that the connection channel between the connection channel 10 and the water collection cup 20 is closed, ensuring the airtightness of the loop between the breathing pipeline 60 and the trachea 70; at the same time, the second switch 50 is in the open state, allowing the water in the water collection cup 20 to be discharged through the drainage pipeline 30.
[0026] In the embodiment of the present application, the first switch 40 can be selected as a rotary switch. The second switch 50 can be a rotary switch.
[0027] It should be noted that the condensate drainage device for the breathing connection pipeline connects the water collection cup 20 with the third connection port 13 of the connection channel 10 by rotating the rotary switch. If the rotated rotary switch is in the open state, the water collection cup 20 is connected to the connection channel 10 in a through manner, and the through connection is connected to the third connection port 13, introducing the condensate water above the connection channel 10 into the water collection cup 20. When the rotated rotary switch is in the closed state, the arc area of the rotary switch fits with the third connection port 13 and is in a closed state, without affecting the airtightness of the breathing loop between the breathing pipeline 60 and the trachea 70.
[0028] In the embodiment of the present application, the condensate drainage device of the breathing connection pipeline is used between the ventilator and the patient. For medical staff: The operation of the condensate drainage device of the breathing connection pipeline is simple, saving time and effort; the channel between the third connection port and the water collecting cup is connected through the first switch to introduce the accumulated water on the connection channel into the water collecting cup; when draining the water collecting cup, the channel between the third connection port and the water collecting cup is disconnected by closing the first switch, and after keeping the connection channel, the breathing pipeline and the trachea in a closed state, the second switch is opened to drain the water in the water collecting cup. For patients: The use of the condensate drainage device of the breathing connection pipeline can reduce the infection risk of other diseases and does not affect the patient's assisted ventilation.
[0029] A condensate drainage device for a breathing connection pipeline provided by the present application includes a connection channel, a water collecting cup and a drainage pipeline. The connection channel is provided with a first connection port, a second connection port and a third connection port. The third connection port is connected to the water inlet of the water collecting cup, the water outlet of the water collecting cup is connected to the drainage pipeline, a first switch is arranged between the third connection port and the water inlet of the water collecting cup, and a second switch for draining the water in the water collecting cup is arranged on the drainage pipeline. The condensate drainage device of the breathing connection pipeline connects the channel between the third connection port and the water collecting cup through the first switch to introduce the accumulated water on the connection channel into the water collecting cup; when draining the water collecting cup, the channel between the third connection port and the water collecting cup is disconnected by closing the first switch, and after keeping the connection channel, the breathing pipeline and the trachea in a closed state, the second switch is opened to drain the water in the water collecting cup. The use of the condensate drainage device of the breathing connection pipeline can reduce the infection risk of other diseases and does not affect the patient's assisted ventilation, and solves the technical problems of tube detachment and easy bacterial growth in the condensate drainage of the breathing circuit between the existing ventilator and the patient.
[0030] As Figure 1 shown, in an embodiment of the present application, inclined blocks 14 for condensate convergence transition and anti-backflow are arranged on the connection channel 10 on both sides of the third connection port 13.
[0031] It should be noted that the inclination angle of the inclined block 14 is 8° - 15°. In this embodiment, one end of the inclined block 14 is connected to the lower port of the first connection port 11 or the second connection port 12, and the other end of the inclined block 14 is connected to the port of the third connection port 13. In this embodiment, the setting of the inclination angle of the inclined block 14 plays a role in the natural transition of condensate collection. When the condensate in the connection pipeline 10 gathers at the third connection port 13, the gathered condensate flows into the water collecting cup 20 through the inclined wave of the inclined block 14 due to the action of gravity. When the condensate drainage device of the breathing connection pipeline is in an inclined state, the inclined block 14 can also prevent the water in the water collecting cup 20 from flowing back, achieving the anti-backflow effect.
[0032] As Figure 1 and Figure 2As shown, in an embodiment of the present application, a buffer area for preventing backflow of the water collecting cup 20 is provided on the water collecting channel of the first switch 40.
[0033] Embodiment 2:

[0035] It should be noted that the content of the condensate discharge device of this respiratory connection pipeline has been described in Embodiment 1, and the content of the condensate discharge device of the respiratory connection pipeline will not be repeated in this embodiment. The operation of this respiratory connection pipeline is simple, saving time and effort; the accumulated water on the connection channel is introduced into the water collecting cup by connecting the channel between the third connection port and the water collecting cup through the first switch; when draining the water collecting cup, the channel between the third connection port and the water collecting cup is closed and disconnected by the first switch, and after keeping the connection channel, the respiratory pipeline and the trachea in a closed state, the second switch is opened to drain the water in the water collecting cup.
