Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a novel automatic condensed water collecting device for ventilators. Background Art

[0002] Ventilator-associated pneumonia (VAP) is the most common nosocomial infection. In intensive care units, the incidence of VAP is 9%-80%, and the mortality rate is 20%-90%. Related literature reports that the biggest culprit of ventilator-associated pneumonia (VAP) is condensation backflow. Pathogens can easily parasitize and reproduce in condensation. In this case, a large number of bacteria in the patient's exhaled gas will be mixed with the condensation in the ventilator pipeline. If the water vapor and condensation sent by the heater flow back to the humidifier tank, the humidified bacteria-containing gas can be inhaled into the lower respiratory tract, or when the patient is turned, the bacteria-containing condensation directly flows into the lower respiratory tract, which can cause VAP.

[0003] If condensate is not dumped out in time, it will cause the following problems: (1) Condensate will generate flow velocity in the circuit, thereby increasing false triggering of the ventilator and increasing the risk of human-machine conflict; (2) Condensate will directly flow back into the airway when the airflow is too large, causing suffocation; (3) Failure to deal with condensate will increase damage to the ventilator's exhalation valve and flow sensor; (4) Excessive accumulation of condensate and failure to dump it out in time will reduce the inner diameter of the pipeline, thereby increasing airway resistance. If the diameter of the pipeline is reduced by 1 times, the airway resistance will increase by 16 times. The increase in airway resistance will increase the patient's work of breathing and reduce tidal volume.

[0004] Based on this, the utility model proposes a novel automatic condensate collection device for a ventilator. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, a new type of automatic collection device for condensed water of a respirator according to an embodiment of the utility model may include a water collection cup 1, an automatic drainage control mechanism and a water collection bag 3, wherein the water collection cup 1 is connected to the respirator, and a water outlet 2 is provided at the bottom of the water collection cup 1; the automatic drainage control mechanism is installed at the bottom of the inner wall of the water collection cup 1, and the automatic drainage control mechanism may include: a connecting pipe 4, a supporting assembly and a buoyancy ball 5, wherein the connecting pipe 4 is fixedly connected to the bottom of the water collection cup 1 and is communicated with the water outlet 2; the supporting assembly is fixedly connected to the top of the connecting pipe 4, and the supporting assembly is provided with a water outlet 19, and the water outlet 19 is communicated with the connecting pipe 4; the buoyancy ball 5 is placed in the supporting assembly and is located at the water outlet 19, and the buoyancy ball 5 blocks the water outlet 19 under the action of its own gravity; the water collection bag 3 is communicated with the water outlet 2.

[0026] In one embodiment of the present invention, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the support assembly may include a connecting cover 6 and a connecting body 7, wherein the connecting cover 6 is in a truncated cone shape, and the connecting cover 6 is provided with an opening 8 at equal angles with the center of the circle as the center; the connecting body 7 is in a cylindrical shape, and the connecting body 7 is fixedly connected to the bottom of the connecting cover 6, and a circular groove 9 adapted to the buoyancy ball 5 is provided on the connecting body 7, and the water outlet 19 is provided on the connecting body 7, and the water outlet 19 is connected to the circular groove 9, and the outer wall of the buoyancy ball 5 is attached to the inner wall of the circular groove 9.

[0027] In a specific embodiment of the utility model, the buoyancy ball 5 is made of solid plastic material with a certain gram weight. The inner wall of the circular groove 9 on the surface of the buoyancy ball 5 is smooth. After the buoyancy ball 5 is placed in the circular groove 9, it will not get stuck inside. The condensed water generated by the ventilator enters the water storage cup 1. As the liquid level in the cup rises, when the buoyancy is greater than the gravity of the buoyancy ball 5, the buoyancy ball 5 rises and breaks away from the circular groove 9. The condensed water will flow from the water outlet 19 through the connecting pipe 4 and the water outlet pipe into the water collection bag 3. After the condensed water flows out, the buoyancy decreases. When the buoyancy is less than the gravity, the buoyancy ball 5 falls back into the circular groove 9 to block the water outlet 19, thereby realizing the collection and discharge of condensed water in a reciprocating manner.

[0028] In one embodiment of the present invention, Figure 5 As shown, a connecting rope 10 is connected between the buoyancy ball 5 and the connecting cover 6 .

[0029] When the buoyancy ball 5 floats up, under the action of the connecting rope 10, the buoyancy ball 5 will not float to the surface of the condensed water, and will not float up and will not exceed the end surface height of the connecting cover 6. When the condensed water is discharged, the buoyancy ball 5 will not be separated from the connecting cover 6 when it descends, and can accurately fall back into the circular groove 9.

[0030] In one embodiment of the utility model, when the buoyancy ball 5 is attached to the inner wall of the circular groove 9 , the opening 8 is located below the center of the buoyancy ball 5 , and after the condensed water level rises, it first enters the connection cover 6 through the opening 8 .

[0031] In one embodiment of the present invention, Figure 2 As shown, the water collection cup 1 may include a cup head 11 and a cup body 12, the cup head 11 and the cup body 12 are threadedly connected, the cup head 11 is provided with a connector 13 and a connector 2 14, and the connector 1 13 and the connector 2 14 are connected to the ventilator.

[0032] In one embodiment of the present invention, Figure 2As shown, a drain pipe 15 is connected between the input end of the water collecting bag 3 and the water outlet end 12. In addition, a one-way valve is provided in the input end of the water collecting bag 3 to prevent the water in the water collecting bag 3 from flowing back. A water outlet end 16 is provided at the bottom of the water collecting bag 3. A plug 17 is connected to the water outlet end 16. The plug 17 and the water outlet end 16 are threadedly connected. The water collecting bag 3 is provided with scale lines 18 and a hanging rope 20.

[0033] In the present invention, the water collecting bag 3 is transparent, and the content of condensed water in the water collecting bag 3 can be observed in combination with the scale line 18, so that the water in the water collecting bag 3 can be discharged in time.

[0034] According to the novel automatic condensate collection device for a ventilator in the embodiment of the utility model, automatic drainage control mechanism is provided to realize automatic drainage of condensate, thereby avoiding the occurrence of hypoxia and pneumonia caused by untimely drainage.
