Description

Technical Field

[0001] The present invention relates to the technical field of ventilator pipelines, and particularly relates to a movable water collecting cup type ventilator pipeline. Background Art

[0002] Mechanical ventilation is the most timely and effective treatment means for respiratory failure caused by various reasons, and is widely used in the departments of respiratory medicine, thoracic surgery, emergency department, intensive care unit, operating room, geriatric ward, infectious disease ward, etc. During the process of mechanical ventilation, continuous humidification is required to avoid airway dryness, airway mucosal damage, and difficult expulsion of dried sputum crusts. However, the humidification and the exhaled gas of the patient contain a large amount of water vapor. When the inhaled and exhaled gases pass through the ventilator circuit, they will be condensed to form condensed water. The "Clinical Application Guidelines for Mechanical Ventilation" issued by the Chinese Society of Critical Care Medicine recommends that "the condensed water in the ventilator pipeline should be removed in a timely manner", and the recommendation level is B.

[0003] The water collecting cup is precisely designed to collect condensed water and promote the drainage of condensed water from the ventilator pipeline. However, in the process of clinical practice, we found that due to factors such as the needs of patient treatment, the placement of body positions, and the relative positions of the ventilator and the hospital bed, it is often difficult for the water collecting cups of the exhalation tube and the inhalation tube to be at the lowest position at the same time. As a result, the condensed water cannot flow into the water collecting cup, but accumulates in the ventilator pipeline, causing the ventilator pipeline to be narrowed or even blocked, thereby affecting the mechanical ventilation effect, and even causing reflux aspiration, leading to asphyxia or pulmonary infection, etc., thus threatening the life safety of patients. The accumulation and reflux of condensed water will affect the mechanical ventilation effect and increase the occurrence of ventilator-associated pneumonia. Therefore, it is required that the water collecting cup for collecting condensed water should be placed at a low position for easy collection of condensed water, and the condensed water in the ventilator pipeline should be removed in a timely manner.

[0004] In the actual clinical process, after many attempts, we found that it is very difficult to place the water collecting cups of the two circuits at the lowest position at the same time; the water collecting cup at the lowest position of the ventilator circuit can smoothly collect condensed water, while the water collecting cup not at the lowest position cannot collect condensed water, resulting in the accumulation of condensed water in the ventilator circuit. At this time, it is necessary to manually introduce the condensed water into the water collecting cup to avoid the stenosis or blockage of the ventilator circuit. At the same time, there are many interfaces between the ventilator pipeline and the water collecting cup, and there is no fixing device. Moving patients, moving the ventilator, adjusting the patient's body position, and patient coughing in clinical practice may all cause the connection between the ventilator circuit and the water collecting cup to be disconnected, resulting in ineffective mechanical ventilation and threatening the safety of patients. Summary of the Invention

[0005] To solve the above deficiencies in the prior art, the present invention provides a movable water collecting cup type ventilator pipeline to ensure that the water collecting cup is always located at the lowest position of the ventilator pipeline, effectively collecting the condensed water in the ventilator pipeline.

[0006] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A movable water collecting cup type ventilator pipeline, including an inhalation tube, an exhalation tube, and a water collecting cup. A telescopic part is provided in the middle section of the inhalation tube and the exhalation tube. The telescopic part uses a telescopic tube, and both ends of the telescopic part are connected to ordinary tubes. There are two water collecting cups, and the two water collecting cups are respectively connected to the middle positions of the telescopic tubes of the inhalation tube and the exhalation tube.

[0008] Further, the water collecting cup includes a cup cover and a cup body. The cup cover is threadedly connected to the cup body, and the cup cover is connected to the telescopic tube.

[0009] Further, it also includes scale bars. There are two scale bars, which are strip-shaped. One or more connection holes are respectively provided at both ends. The distance between the two nearest connection holes at both ends of the scale bar is equal to the length of the telescopic tube in its natural state. One or more fixing structures are respectively provided at the connections between both ends of the telescopic parts of the inhalation tube and the exhalation tube and the ordinary tubes. The scale bars are connected to the fixing structures of the inhalation tube or the exhalation tube through the connection holes.

[0010] Preferably, the connection holes of the scale bars are circular or square.

[0011] Preferably, the fixing structure is a pair of inverted "L" shaped hooks arranged oppositely, and the connection holes of the scale bar are sleeved in the hooks.

[0012] Further, a sliding groove is provided on the scale bar; a connecting part is provided at the top of the cup cover, and an internal thread is provided on the connecting part; it also includes a sliding rod, which includes a head and a cylindrical rod part. An external thread adapted to the internal thread of the connecting part of the cup cover is provided at one end of the rod part away from the head; the rod part of the sliding rod passes through the sliding groove of the scale bar and is threadedly connected to the cup cover.

[0013] Preferably, the head of the sliding rod is cylindrical.

[0014] Preferably, the head of the sliding rod is spherical.

[0015] Preferably, the cup cover and the telescopic tube are integrally formed.

[0016] Preferably, the cup cover and the telescopic tube are connected through an interface.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The movable water collecting cup type breathing machine pipeline of the present invention can adjust the lengths of the telescopic pipes on both sides of the water collecting cup by setting a telescopic part, and move the relative position of the water collecting cup upward, so that the water collecting cup is always at the lowest position of the breathing machine pipeline; further, by setting a scale bar, it can be ensured that during the movement of the water collecting cup, the total length of the telescopic part remains unchanged, avoiding problems such as excessive pipeline length causing pulling and unstable connection of the interface between the water collecting cup and the breathing machine pipeline; furthermore, by setting a sliding rod, the sliding rod presses the scale bar to contact the cover body of the water collecting cup. On the one hand, it restricts the scale bar from falling off the breathing machine pipeline, and on the other hand, it can restrict the telescopic pipe from returning to its natural state after adjusting the position of the water collecting cup, ensuring the stable position of the water collecting cup.

[0027] The movable water-collecting cup type ventilator pipeline disclosed in the present invention includes an inhalation tube 1, an exhalation tube 2, and a water-collecting cup 3. A telescopic part is provided in the middle section of the inhalation tube 1 and the exhalation tube 2. The telescopic part adopts a telescopic tube 4, and both ends of the telescopic part are connected to ordinary tubes. There are two water-collecting cups 3, and the two water-collecting cups 3 are respectively connected to the middle positions of the telescopic tubes of the inhalation tube 1 and the exhalation tube 2; specifically, the water-collecting cup 3 includes a cup lid 31 and a cup body 32. The cup lid 31 is connected to the telescopic tube, and the cup lid 31 and the cup body 32 are connected by threads. The cup lid 31 can be integrally formed with the telescopic tube 4 or connected through an interface. During use, according to actual needs, the telescopic tube on one side of the water-collecting cup 3 can be stretched or compressed, and the telescopic tube on the other side of the water-collecting cup will be compressed or stretched correspondingly, and the position of the water-collecting cup 3 can be moved until it reaches the lowest position of the ventilator pipeline.

[0028] Embodiment 2:

[0029] The movable water-collecting cup type ventilator pipeline disclosed in the present invention, compared with Embodiment 1, further includes two scale bars 5. The scale bars 5 are in a long strip shape, and one or more connection holes 51 are respectively provided at both ends. The distance between the two closest connection holes at both ends of the scale bar 5 is equal to the length of the telescopic tube in its natural state; one or more fixing structures are respectively provided at the connection positions of the two ends of the telescopic tubes of the inhalation tube 1 and the exhalation tube 2 with the ordinary tubes.

[0033] For the movable water collecting cup type ventilator pipeline disclosed in the present invention, compared with Embodiment 2, the difference lies in that: a sliding groove 52 is further provided on the scale bar 5, a connecting part 33 is provided on the top of the cup cover 31, and an internal thread is provided on the connecting part 33; further included is a sliding rod 6, the sliding rod 6 includes a head in the shape of a cylinder or a sphere and a rod part in the shape of a cylinder, and an external thread adapted to the internal thread of the connecting part 33 of the cup cover 31 is provided at one end of the rod part away from the head; the rod part of the sliding rod 6 passes through the sliding groove 52 of the scale bar 5 and is threadedly connected to the cup cover 31. During use, after moving the water collecting cup to a suitable position, tighten the sliding rod 6 and the cup cover 31, the lower surface of the scale bar 5 is attached to the top surface of the cup cover 31, so that the scale bar and the telescopic pipe of the ventilator pipeline are in a relatively parallel state, and at the same time, the telescopic pipe is restricted from returning to its natural state.

[0034] Certainly, the present invention may also have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
