Description

Technical Field

[0001] The utility model belongs to the technical field of collection devices, and in particular relates to a condensed water collection device for a breathing machine. Background Art

[0002] Mechanical ventilation is one of the important means of life support for critically ill patients. As a necessary medical device for mechanical ventilation, it is crucial to standardize the use and management of ventilators and their accessories. A large number of studies have confirmed that ventilator-associated pneumonia is closely related to the use of ventilators. The condensed water formed in the respiratory tract by the heated gas of the ventilator humidifier and the gas exhaled by the patient is a high-risk factor for ventilator-associated pneumonia. At the same time, the condensed water contains bacteria or viruses in the patient's body. When the condensed water in the collection bottle is dumped, it is easy to cause the condensed water droplets carrying bacteria or viruses to splash, causing pollution to the surrounding environment, greatly increasing the risk of infection for medical staff and other patients. Effective management of condensed water can reduce or prevent the occurrence of ventilator-associated pneumonia and reduce the amount of bacterial contamination on the surface of the environment.

[0003] In the prior art, after searching, the utility model patent with Chinese patent publication number CN212547898U discloses a ventilator condensate collection bottle, such as Figure 1 As shown, it mainly includes a pipeline a connected to the ventilator, and a collection bottle b is connected below the pipeline a. The collection bottle b includes a bottle cap b1 and a bottle body b2, and the bottle cap is connected to the pipeline. After the collection bottle is full, the bottle body is unscrewed and then directly dumped.

[0004] The ventilator condensate collection device similar to the above-mentioned technical solution in the prior art was found to have the following defects during use: in order to avoid the dripping of condensate continuously generated by the ventilator, the ventilator needs to be in a shutdown state when pouring out the condensate in the collection bottle, which increases the number of times the ventilator is disconnected and increases the risk of ventilator-associated pneumonia. Utility Model Content

[0005] In view of the shortcomings and defects in the prior art, the purpose of the utility model is to provide a condensate collection device for a ventilator, which solves the problem that in order to avoid the dripping of condensate continuously generated by the ventilator, the ventilator needs to be in a shutdown state when pouring out the condensate in the collection bottle, which increases the number of times the ventilator is disconnected and increases the risk of ventilator-associated pneumonia.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a condensate collection device for a ventilator, comprising a plurality of hoses respectively connected to the ventilators, every two hoses being commonly connected to a collecting vial, a dripping port being arranged at the bottom of the collecting vial, a one-way check valve being arranged at the dripping port, the dripping port of each collecting vial being connected to a through pipe via a cannula, a plurality of through pipes being commonly connected to an interface, the interface being connected to a large collecting bottle, a first liquid level sensor being arranged near the upper side inside the large collecting bottle, a second liquid level sensor being arranged near the upper side inside the collecting vial, the first liquid level sensor being electrically connected to an alarm and a one-way check valve respectively, and the second liquid level sensor being electrically connected to the one-way check valve.

[0007] As a further improvement of the utility model, the collecting vial is made of transparent material.

[0008] As a further improvement of the utility model, the interface is detachably connected to the large collection bottle.

[0009] As a further improvement of the utility model, a liquid outlet is provided at the bottom of the large collecting bottle.

[0010] As a further improvement of the utility model, the large collecting bottle is made of transparent material.

[0011] As a further improvement of the utility model, a scale is provided on the large collecting bottle.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. By connecting every two hoses together with a collecting vial, each of the collecting vials is connected to a collecting large bottle through a through pipe, and a one-way check valve is provided at the dripping port of the collecting vial, the condensed water generated by the ventilator first flows to the collecting vial for temporary storage, and then flows from the collecting vial to the collecting large bottle when the collecting vial is almost full. When processing the condensed water, the collecting large bottle can be directly unscrewed for processing. That is, after removing the collecting large bottle, because there is still a collecting vial connected to the ventilator, the condensed water generated by the ventilator can flow to the collecting vial for temporary storage, without having to shut down the ventilator. This is simple and convenient, reduces the number of times the ventilator is disconnected, and reduces the risk of droplet transmission and the risk of ventilator-associated pneumonia.

[0014] In addition, a first liquid level sensor is provided on the large collecting bottle, and a second liquid level sensor is provided on the small collecting bottle. The first liquid level sensor is electrically connected to the alarm and the one-way check valve respectively, and the second liquid level sensor is electrically connected to the one-way check valve. When the first liquid level sensor detects that the liquid in the large collecting bottle is full, it will control the alarm to sound an alarm, prompting the staff to deal with the liquid in the large collecting bottle in time, and at the same time, send a signal to the one-way check valve to close the one-way check valve to avoid that when the large collecting bottle is removed, the dripping mouth of the small collecting bottle still drips liquid downward to avoid cross infection; and when the second liquid level sensor on the small collecting bottle detects that the liquid in the small collecting bottle is full, it will control the one-way check valve to open, thereby directing the liquid into the large collecting bottle.

[0015] 2. By making the collecting vial and the collecting large bottle with transparent materials, it is convenient to observe the liquid in the collecting vial and the collecting large bottle.

[0016] 3. By arranging a liquid outlet nozzle on the large collection bottle, the liquid in the large collection bottle can be diverted out through the liquid outlet nozzle, which is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model embodiment discloses a condensed water collection device for a ventilator. Figure 2A condensate collection device for a ventilator comprises a plurality of hoses 2 respectively connected to a ventilator 1, wherein every two hoses 2 are commonly connected to a collecting vial 3, a dripping port 4 is arranged at the bottom of the collecting vial 3, a one-way check valve is arranged at the dripping port 4, the dripping port 4 of each collecting vial 3 is connected to a through pipe 5 through a pluggable insert 6, a plurality of through pipes 5 are commonly connected to an interface 10, the interface 10 is detachably connected to a collecting large bottle 7 through a thread, a first liquid level sensor 8 is arranged near the upper side inside the collecting large bottle 7, a second liquid level sensor 9 is arranged near the upper side inside the collecting vial 3, the first liquid level sensor 8 is electrically connected to an alarm 13 and a one-way check valve respectively, and the second liquid level sensor 9 is electrically connected to the one-way check valve.

[0024] In addition, the above-mentioned collecting vial 3 and collecting large bottle 7 are both made of transparent materials. The collecting large bottle 7 is provided with a scale 12 to facilitate observation of the liquids in the collecting vial 3 and the collecting large bottle 7. In addition, a liquid outlet 11 can be provided at the bottom of the collecting large bottle 7, and the liquid in the collecting large bottle 7 can also be diverted out through the liquid outlet 11, which is simple and convenient.
