Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a ventilator tubing assembly and a ventilator using the tubing assembly. Background Technology

[0002] A ventilator is a medical device that can prevent and treat respiratory failure and save and prolong the lives of patients. When using a ventilator, in order to prevent the patient's airway from drying out, the gas in the breathing tube is usually humidified. The humidification device heats water to produce water vapor, and then mixes the water vapor with oxygen and introduces it into the patient's airway to achieve the effect of heating and humidification.

[0003] During the humidification of the gas, condensation usually forms inside the breathing tube. Currently, a condensation collection cup is commonly used to collect this condensation. However, although current condensation collection cups can collect most of the condensation, the inventors discovered that current ventilators still have shortcomings in use, specifically:

[0004] Normally, the collection cup collects condensate based on the flow of the condensate itself, that is, the condensate flows into the collection cup along the wall of the breathing tube under the action of gravity. However, there is also a situation where some condensate adheres to the tube wall. Because the condensate adhering to the tube wall has a small mass, it is difficult for the condensate to flow under its own gravity. Thus, when the condensate adheres to the tube wall for a long time, bacteria can easily grow in the condensate, thereby increasing the risk of ventilator-associated pneumonia.

[0005] Therefore, how to prevent condensate from adhering to the walls of the breathing duct for a long time is a technical problem that urgently needs to be solved. Utility Model Content

[0006] The purpose of this invention is to address the current situation where some condensate adheres to the wall of the breathing tubing for a long time, by providing a ventilator tubing assembly and a ventilator using the assembly, so as to prevent the condensate from adhering to the wall of the breathing tubing for a long time.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A ventilator tubing assembly includes a breathing tubing for gas delivery, one end of which is connected to a water collection cup. A cleaning ring is disposed inside the breathing tubing, through which gas can pass. A magnet is disposed outside the breathing tubing to attract the cleaning ring. When the magnet moves along the length of the breathing tubing, the cleaning ring moves along the length of the breathing tubing, in addition to attracting the cleaning ring.

[0009] The cleaning ring includes a cleaning layer that contacts the inner wall of the breathing tube and absorbs condensate on the inner wall. An abutment is provided at the end of the breathing tube that connects to the water collection cup. This abutment abuts against the cleaning layer. By moving the magnet, the cleaning ring can be moved along the length of the breathing tube, causing the cleaning layer to be squeezed against the abutment, thereby squeezing out the condensate from the cleaning layer. The squeezed-out condensate flows into the water collection cup.

[0010] As the preferred technical solution of this application, the cleaning layer is an absorbent sponge.

[0011] As the preferred technical solution of this application, the cleaning layer has a cylindrical structure, and the outer wall of the cleaning layer is used to contact the inner wall of the breathing tube.

[0012] As the preferred technical solution of this application, the abutment is detachably installed in the breathing tube by means of a threaded connection;

[0013] Furthermore, after the breathing tube is separated from the water cup and the abutment is removed from the breathing tube, the cleaning ring can be removed from the breathing tube.

[0014] As the preferred technical solution of this application, a groove is formed on the abutment, and the cross-section of the groove is arc-shaped or V-shaped. When the abutment is pressed against the cleaning layer, the cleaning layer is pressed into the groove. A flow channel is provided at the bottom of the groove for discharging liquid from the groove.

[0015] As a preferred technical solution of this application, the cleaning ring further includes a ring body, which is made of metal material and is used to be attracted by a magnet.

[0016] As the preferred technical solution of this application, the outer side of the ring body is wrapped with a silicone layer, which is used to prevent the ring body from contacting the gas in the breathing tube.

[0017] As the preferred technical solution of this application, the magnet is ring-shaped and the magnet is radially magnetized so that the magnetic poles of the magnet are distributed in the inner and outer rings.

[0018] This invention also provides a ventilator, including the ventilator tubing assembly described above.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In the scheme of this application, by controlling the movement of a magnet outside the breathing tube, the operator holds the magnet and moves it along the length of the breathing tube. Based on the magnet attracting the cleaning ring, the cleaning ring moves along the length of the breathing tube, and the cleaning layer on the cleaning ring can contact the inner wall of the breathing tube, thereby absorbing the condensate on the inner wall of the breathing tube. By moving the cleaning ring closer to the abutment, the cleaning layer is squeezed against the abutment, thereby squeezing out the condensate absorbed in the cleaning layer. The condensate is squeezed out and flows into the collection cup, thereby avoiding the condensate from adhering to the inner wall of the breathing tube for a long time, thus reducing the risk of ventilator-associated pneumonia in patients. Furthermore, medical staff can control the movement of the magnet at any time, making the cleaning of condensate on the inner wall of the breathing tube more convenient and flexible.

[0021] 2. Furthermore, the abutment is threaded onto the breathing tube, which improves the ease of disassembly and assembly of the abutment. At the same time, after the water collection cup is separated from the breathing tube and the cleaning component is removed from the breathing tube, the cleaning ring can be taken out from inside the breathing tube. That is, the cleaning ring is taken out from the end of the breathing tube that is connected to the water collection cup, which facilitates the replacement or cleaning of the cleaning ring.

[0022] 3. Furthermore, by setting a groove and making the cross-section of the groove arc-shaped or V-shaped, the cleaning layer can be squeezed into the groove when the contact part is pressed against the cleaning layer. At the same time, the squeezed-out condensate can flow along the flow channel until it flows into the water collection cup. In this way, the stability of the cleaning layer is further improved.

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Example 1: This example provides a ventilator tubing assembly, see [link to example]. Figures 1-3 As shown, the device includes a breathing tube 1 for gas delivery. One end of the breathing tube 1 is connected to a water collection cup 2. A cleaning ring 3 is provided inside the breathing tube 1, allowing gas to pass through the cleaning ring 3. A magnet 4 is provided outside the breathing tube 1 to attract the cleaning ring 3. When the magnet 4 moves along the length of the breathing tube 1, the cleaning ring 3 also moves along the length of the breathing tube 1, based on the attraction of the cleaning ring 3 by the magnet 4.

[0033] The cleaning ring 3 includes a cleaning layer 5, which is used to contact the inner wall of the breathing tube 1 and absorb the condensate on the inner wall of the breathing tube 1. The end of the breathing tube 1 that is connected to the water collection cup 2 is provided with an abutment 6, which is used to abut against the cleaning layer 5. By moving the magnet 4, the cleaning ring 3 can be moved along the length of the breathing tube 1, and the cleaning layer 5 and the abutment 6 can be squeezed to squeeze out the condensate in the cleaning layer 5. After being squeezed out, the condensate can flow into the water collection cup 2.

[0034] In this application, the movement of the magnet 4 is controlled outside the breathing tube 1. The operator holds the magnet 4 and moves it along the length of the breathing tube 1. Based on the attraction of the cleaning ring 3 by the magnet 4, the cleaning ring 3 moves along the length of the breathing tube 1. The cleaning layer 5 on the cleaning ring 3 can contact the inner wall of the breathing tube 1, thereby absorbing the condensate on the inner wall of the breathing tube 1. By moving the cleaning ring 3 towards the abutment 6, the cleaning layer 5 is squeezed against the abutment 6, thereby squeezing out the condensate absorbed in the cleaning layer 5. The condensate flows into the water collection cup 2 after being squeezed out, thus avoiding the condensate from adhering to the inner wall of the breathing tube 1 for a long time, thereby reducing the risk of ventilator-associated pneumonia in patients. Furthermore, medical staff can control the movement of the magnet 4 at any time, making the cleaning of condensate on the inner wall of the breathing tube 1 more convenient and flexible.

[0035] Meanwhile, the connection method between the breathing tube 1 and the water collection cup 2 in this application is existing technology, so it will not be described in detail here.

[0036] As a preferred embodiment, based on the above method, the cleaning layer 5 is further described as an absorbent sponge.

[0037] Furthermore, making the cleaning layer 5 an absorbent sponge can improve the water absorption performance of the cleaning layer 5. At the same time, after the cleaning layer 5 is squeezed against the contact part 6, it is easier to squeeze out the condensed water from the sponge, making it easier for the water collection cup 2 to collect the condensed water.

[0038] As a preferred embodiment, based on the above method, the cleaning layer 5 is further provided to have a cylindrical structure, and the outer wall of the cleaning layer 5 is used to contact the inner wall of the breathing tube 1.

[0039] Furthermore, by setting the cleaning layer 5 into a cylindrical structure so that the gas in the breathing tube 1 can pass through the cleaning layer 5, the convenience of absorbing condensate on the inner wall of the breathing tube 1 is improved without obstructing gas flow.

[0040] As a preferred embodiment, based on the above method, the abutment member 6 is further provided in the breathing tube 1 by means of a threaded connection;

[0041] Furthermore, after the breathing tube 1 is separated from the water cup 2 and the abutment 6 is removed from the breathing tube 1, the cleaning ring 3 can be removed from the breathing tube 1.

[0042] Furthermore, the abutment 6 is threaded onto the breathing tube 1, which improves the ease of disassembly and assembly of the abutment 6. At the same time, after the water cup 2 is separated from the breathing tube 1 and the cleaning component is removed from the breathing tube 1, the cleaning ring 3 can be removed from the breathing tube 1. That is, the cleaning ring 3 is removed from the end of the breathing tube 1 that is connected to the water cup 2, which facilitates the replacement or cleaning of the cleaning ring 3.

[0043] As a preferred embodiment, based on the above method, the abutment 6 is further provided with a groove 7, the cross-section of the groove 7 is arc-shaped or V-shaped, when the abutment 6 is pressed against the cleaning layer 5, the cleaning layer 5 is pressed into the groove 7, and a flow channel 8 is provided at the bottom of the groove 7 for discharging liquid in the groove 7.

[0044] Furthermore, by setting the groove 7 and making the cross-section of the groove 7 arc-shaped or V-shaped, the cleaning layer 5 can be squeezed into the groove 7 when the contact member 6 is pressed against the cleaning layer 5. At the same time, the squeezed-out condensate can flow along the flow channel 8 until it flows into the water collection cup 2. In this way, the stability of the pressing of the cleaning layer 5 is further improved.

[0045] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-3 As shown, the cleaning ring 3 also includes a ring body 9, which is made of metal and is used to be attracted by the magnet 4.

[0046] Furthermore, by making the ring body 9 out of metal, the ring body 9 is attracted by the magnet 4, thereby improving the ease with which the magnet 4 can move the ring body 9.

[0047] As a preferred embodiment, based on the above method, the outer side of the ring body 9 is further wrapped with a silicone layer 10, which is used to prevent the ring body 9 from contacting the gas in the breathing tube 1.

[0048] Furthermore, by providing a silicone layer 10, the outer side of the ring body 9 is wrapped with silicone, thereby preventing the ring body 9 from contacting the gas in the breathing tubing 1, thus avoiding contamination of the gas inhaled by the patient by the metal ring body 9, and improving the safety of the ventilator tubing assembly of this application during use.

[0049] As a preferred embodiment, based on the above method, the magnet 4 is further formed into a ring, and the magnet 4 is radially magnetized so that the magnetic poles of the magnet 4 are distributed in the inner and outer rings.

[0050] Furthermore, the magnet 4 is radially magnetized so that the inner ring of the magnet 4 becomes magnetic, thereby attracting the cleaning ring 3 in the breathing tube 1, thus causing the magnet 4 to drive the cleaning ring 3 to move, thereby improving the convenience of driving the cleaning ring 3 to move.

[0051] Example 3: This example provides a ventilator, including the ventilator tubing assembly described above. See [link to example]. Figure 1 The ventilator tubing components.

[0052] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
