[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In order to facilitate understanding of the technical solution of the present application, the existing intubation tube is explained here: when suction or fiberbronchoscopy is required for a patient, the suction tube or fiberbronchoscope needs to be inserted into the intubation tube, especially during fiberbronchoscopy, the intubation tube may be repeatedly inserted. In order to avoid the suction tube or fiberbronchoscope from scratching the patient's trachea, it is necessary to apply water-based or oil-based lubricant to the surface of the suction tube or fiberbronchoscope before insertion. The process is relatively cumbersome and affects the operation efficiency. In addition, for pediatric patients, the fiberbronchoscope is thinner than that of adults, and there may be leakage when inserted through the existing intubation tube.

[0026] On the one hand, if Figure 1 and Figure 2 As shown, an embodiment of the present application provides a connection assembly 100 for a ventilator, including a first connection tube 110 and a second connection tube 120. The first connection tube 110 includes an insertion section 111, a conduction section 112 and a connection section 113 that are connected in sequence, and the insertion section 111 and the connection section 113 are respectively located at two ends of the first connection tube 110. One end of the second connection tube 120 is connected to the first connection tube 110 and is arranged corresponding to the conduction section 112, and the other end of the second connection tube 120 away from the first connection tube 110 is connected to the ventilator.

[0027] It is understandable that the second connecting tube 120 is arranged corresponding to the conducting section 112 , that is, a connecting port is opened on the side wall of the first connecting tube 110 , the connecting port is arranged corresponding to the conducting section 112 , and the second connecting tube 120 is connected to the connecting port to directly communicate with the conducting section 112 .

[0028] Furthermore, the connection assembly also includes a lubrication structure 130 , which is disposed in the insertion section 111 , and the lubrication structure 130 can lubricate the surface of the component inserted into the insertion section 111 .

[0029] The above-mentioned connecting assembly is used to connect the second connecting tube 120 to the ventilator, and the cannula is connected to the connecting section 113 to achieve the connection between the ventilator and the cannula. At the same time, when it is necessary to insert an insert (suction tube or fiber bronchoscope), the insert is sequentially inserted into the above-mentioned insert section 111, the conducting section 112 and the connecting section 113, and then enters the cannula and the patient's body. When the insert passes through the insert section 111, the lubricating structure 130 can lubricate the surface of the insert. In this way, the operation of inserting the insert is more convenient, and the operating efficiency is effectively improved.

[0030] It can be confirmed that in other embodiments, the insert may be other and is not limited here.

[0031] In one embodiment, the insertion section 111 , the conducting section 112 , and the connecting section 113 are coaxially arranged to facilitate the insertion of the insert through the insertion section 111 and into the patient's body through the cannula.

[0032] In one embodiment, the lubricating structure 130 includes a porous member and a lubricant, wherein the porous member is disposed in the inserting section 111, and the aqueous or oily lubricant is filled in the porous member. Specifically, the porous member is a sponge, or other water-absorbent material that absorbs the lubricant.

[0033] It can be confirmed that a channel is opened through the porous member for components such as inserts to pass through, and the size of the channel is smaller than that of the inserts. However, since the porous member is flexible, it can be stretched open, thereby ensuring sealing while allowing the inserts to pass through.

[0034] In one embodiment, the connecting assembly further includes a first valve 140 and a second valve 150. The first valve 140 is disposed at the entrance of the insertion section 111, and the second valve 150 is disposed between the insertion section 111 and the conducting section 112 to limit the lubrication structure 130 and prevent gas leakage and splashing during the insertion of the insert.

[0035] It is understandable that the second valve 150 is sealed and connected to the inner wall of the first connecting tube 110. In addition, the lubricating structure 130 is filled with lubricant, so when the insert passes through, the sealing can be further ensured to avoid gas leakage.

[0036] In one embodiment, the first valve 140 is detachably provided to facilitate replacement of the lubricating structure 130 of the insertion section 111. Specifically, after the lubricating structure 130 has been used multiple times, the first valve 140 can be removed and then the lubricating structure 130 can be replaced. Since the second valve 150 is provided between the insertion section 111 and the conducting section 112, there will be no gas leakage when replacing the lubricating structure 130.

[0037] Furthermore, the first valve 140 includes a connecting portion and a main body portion. The connecting portion is used to be detachably connected to the first connecting tube 110 , and the main body portion is connected to the connecting portion to seal the insertion section 111 and allow components to pass through.

[0038] It should be noted that the main body and the second valve 150 are both made of silicone material to ensure sealing. In addition, the connection portion can be threadedly connected to the first connecting tube 110 to ensure sealing. Of course, it can also be an interference connection.

[0039] In one embodiment, the second connecting tube 120 is a telescopic tube, so that the length of the second connecting tube 120 can be adjusted according to the position of the patient and the ventilator, while also being able to reserve a certain amount of telescopic capacity to prevent the second connecting tube 120 from being separated from the ventilator.

[0040] In one embodiment, the connection component also includes a drug inlet tube (not shown), which is connected to the second connection tube 120 and is arranged corresponding to the conductive section 112. That is, like the second connection tube 120, the drug inlet tube is connected to the side wall of the first connection tube 110 and is directly connected to the conductive section 112. In this way, drugs can be introduced into the patient's body through the drug inlet tube.

[0041] Furthermore, the connection assembly also includes a flow regulating valve (not shown), which is arranged on the drug inlet tube and is used to regulate the flow of the drug in the drug inlet tube.

[0042] It should be noted that a sealing cap is also provided at one end of the drug inlet tube away from the first connecting tube 110, and the sealing cap is used to seal the drug inlet tube so as to seal the drug inlet tube when no drug is infused to avoid gas leakage.

[0043] On the other hand, an embodiment of the present application further provides a ventilator system, which includes a ventilator, a cannula, and a connecting assembly for the ventilator in the above embodiment.

[0044] In order to facilitate understanding of the technical solution of this application, Figure 1 The application of the ventilator system in the above embodiment is described as follows:

[0045] Insert the cannula into the patient's body, and connect the cannula to the connecting section 113 of the first connecting tube 110, and connect the ventilator to the second connecting tube 120. When suctioning or fiberbronchoscope operation is required, the suction tube or fiberbronchoscope is passed through the first valve 140, the lubricating structure 130 and the second valve 150 in sequence, and then through the conducting section 112 and the connecting section 113 to enter the cannula and the patient's body, and then the corresponding operation can be performed. When it is necessary to input drugs, open the sealing cover on the drug input tube, and then input drugs into the patient's body through the drug input tube. The flow rate of the drug can be adjusted by the flow regulating valve during the input process.

[0046] In summary, the connection assembly and ventilator system provided by the present application have at least the following advantages:

[0047] 1. The operator can directly insert the suction tube or fiber bronchoscope, and the lubricating structure 130 can lubricate the surface of the suction tube or fiber bronchoscope during the insertion process, without applying lubricant before insertion, which is convenient for operation and improves operation efficiency;

[0048] 2. The arrangement of the first valve 140 and the second valve 150 can prevent gas leakage during the insertion of a suction tube or a fiber bronchoscope, and can also prevent gas leakage during the replacement of the lubrication structure 130.

[0049] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
