Technical Field

[0001] The utility model relates to the technical field of ventilator accessories, in particular to a water collecting cup for a ventilator pipeline with a backflow prevention function. Background Art

[0002] In modern clinical medicine, as an effective means of artificially replacing the spontaneous ventilation function, the ventilator has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupies a very important position in the field of modern medicine; the ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the patient's life; during the use of the ventilator, the condensed water generated flows to the water collection cup in the middle of the pipeline to prevent the condensed water with bacteria from flowing back into the airway;

[0003] In the prior art, the anti-backflow effect between the water collecting cup and the pipeline is poor. When the patient turns over or the medical staff knocks over the water collecting cup, the water in the water collecting cup is easy to flow back into the pipeline, polluting the pipeline, and even causing condensed water to flow back into the patient's lungs, affecting the patient's recovery. In severe cases, it may cause lung infection in the patient and bring danger to the patient. Therefore, we propose a water collecting cup for a ventilator pipeline with an anti-backflow function to solve the above problem. Utility Model Content

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0021] like Figure 1-5 The water collecting cup for a ventilator pipeline with an anti-backflow function shown in the figure comprises: a water collecting cup 1, a scale line 2, a liquid outlet 3, a valve 4, a connecting seat 5, a connecting cavity 6, an inner cavity 7, a bottom plate 8, a through hole 9, a ball 10, and a ventilator pipeline 11. The surface of the water collecting cup 1 is provided with a scale line 2, the bottom of the water collecting cup 1 is fixedly provided with a liquid outlet 3, the inside of the liquid outlet 3 is fixedly provided with a valve 4, the top of the water collecting cup 1 is fixedly provided with a connecting seat 5, the top of the connecting seat 5 is provided with a connecting cavity 6, the bottom of the connecting cavity 6 is provided with an inner cavity 7, the bottom of the inner cavity 7 is fixedly provided with a bottom plate 8, a plurality of through holes 9 are provided on the surface of the bottom plate 8, a round ball 10 is movably provided inside the inner cavity 7, the top of the connecting seat 5 is movably provided with a ventilator pipeline 11, and the bottom of the ventilator pipeline 11 is threadedly connected to the inside of the connecting cavity 6.

[0022] In the present embodiment, the interior of the inner cavity 7 is penetrated by the through hole 9 and the interior of the water collecting cup 1, and the through holes 9 are arranged in an array structure; and the condensed water generated during the use of the ventilator will flow into the connecting cavity 6 through the ventilator pipeline 11, and then flow into the inner cavity 7 through the connecting cavity 6, and finally the condensed water flows into the water collecting cup 3 through the through hole to collect the condensed water.

[0023] In this embodiment, the inner cavity 7 is configured with a conical structure, so that when the water collecting cup 1 is tilted or inverted, the inner cavity 7 will always be in an inclined state, so that the ball 10 will roll along the inner wall of the inner cavity 7 through the gravity of the ball itself, so that the top of the inner cavity 7 can be blocked, and the water collecting cup 1 and the ventilator pipeline 11 can be isolated, so as to prevent the condensed water inside the water collecting cup 1 from flowing back into the ventilator pipeline 11, and the ventilator pipeline 11 can be prevented from being contaminated, and the risk of infection caused by the condensed water flowing back to the patient's lungs is avoided, thereby improving the anti-backflow effect of the ventilator pipeline 11; when the water collecting cup 1 is not tilted or inverted, the ball 10 will fall off the top of the inner cavity 7 to the surface of the bottom plate 8 through the gravity of the ball itself, so that the water collecting cup 1 can collect the condensed water normally.

[0024] In this embodiment, the top of the inner cavity 7 is arranged in an arc-shaped structure, and the ball 10 is adapted to the top of the inner cavity 7, so that the ball 10 is blocked at the top of the inner cavity 7 to make it more sealed.

[0025] In this embodiment, the ball 10 is made of stainless steel so that the ball 10 has its own gravity and is not easy to rust.

[0026] In this embodiment, the water collecting cup 1 is made of a transparent plastic material, so that the amount of condensed water inside the water collecting cup 1 can be easily known.

[0027] The working principle of the water collecting cup for the ventilator pipeline with anti-backflow function mentioned in the utility model is as follows:

[0028] When the ventilator is in use, the condensed water generated during use will flow from the ventilator pipeline 11 into the connecting cavity 6, then flow into the inner cavity 7 through the connecting cavity 6, and finally the condensed water will flow into the water collection cup 3 through the through hole to collect the condensed water;

[0029] When the water collecting cup 1 is tilted or inverted, the inner cavity 7 is set up with a conical structure so that the inner cavity 7 will always be in an inclined state. Therefore, through the action of the ball's own gravity, the ball 10 will roll along the inner wall of the inner cavity 7, thereby blocking the top of the inner cavity 7 and isolating the water collecting cup 1 from the ventilator pipeline 11, thereby preventing the condensed water inside the water collecting cup 1 from flowing back into the ventilator pipeline 11, avoiding contamination of the ventilator pipeline 11, and further avoiding the risk of infection caused by the condensed water flowing back to the patient's lungs, thereby improving the anti-backflow effect of the ventilator pipeline 11; when the water collecting cup 1 is not tilted or inverted, through the ball's own gravity, the ball 10 will break away from the top of the inner cavity 7 and fall to the surface of the bottom plate 8, so that the water collecting cup 1 can collect the condensed water normally.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
