The drawings are schematic diagrams or conceptual diagrams, and the relationship between the thickness and the width of each part, the proportional relationship between each part, and the like are not completely consistent with the actual values thereof.

Fig. 1 and 4 illustrate a disposable bronchoscope kit sputum aspirator and its matched bronchoscope according to one embodiment of the present invention, wherein disposable bronchoscope kit sputum aspirator 10 is adapted for use with bronchoscope 20, and in particular, disposable bronchoscope kit sputum aspirator 10 is adapted for use with insertion tube 200 of bronchoscope 20.

The disposable bronchoscope-matched sputum aspirator 10 comprises a tube body 110, which is similar to the tube body of the existing disposable sputum aspirator, the tube body 110 is of a flexible slender tubular structure, and the tube body 110 is of a special tubular structure unlike the circular tubular tube body structure of the existing disposable sputum aspirator.

As shown in fig. 2 and 3, the pipe wall of the pipe body 110 defines both the suction channel 120 and the fitting channel 130, wherein the suction channel 120 is defined by the inner wall of the pipe body 110 and the fitting channel 130 is defined by the outer wall of the pipe body 110; the suction channel 120 is used for sucking sputum, and is arranged in a closed loop in the circumferential direction, and the fitting channel 130 is used for connecting with the insertion tube 200 of the bronchoscope 20, and is arranged in an open loop in the circumferential direction.

As shown in fig. 5, the channel size of the fitting channel 130 is adapted to the outer diameter of the insertion tube 200 so that the insertion tube 200 can be disposed in the fitting channel 130. The size of the opening 140 of the open loop of the fitting channel 130 is smaller than the outer diameter of the insertion tube 200, and the insertion tube 200 can be inserted into the fitting channel 130 from the opening 140 in combination with the flexibility of the tube body 110, forming a state in which the tube body 110 is wrapped around the insertion tube 200 by the outer wall thereof, at which time the suction channel 120 is disposed at the side of the insertion tube 200, and the port of the suction channel 120 can be disposed at a position close to the distal end of the insertion tube 200, so that sputum aspiration operation can be performed through the disposable-bronchoscopy-matched sputum aspiration tube 10 during a bronchoscopy.

The material for manufacturing the tube body 110 can be a conventional disposable sputum aspirator, and is usually a medical polymer material, such as silica gel or polyurethane, and the material can enable the tube body 110 to be tightly attached to the insertion tube 200 when the tube body 110 is connected with the insertion tube 200, that is, the insertion tube 200 is arranged in the embedded channel 130, so that the insertion tube 200 is not easy to be separated from the opening 140, and meanwhile, the tube body 110 needs to be wrapped around the length of the insertion tube 200 when the disposable sputum aspirator is used, so that enough friction force exists between the disposable sputum aspirator and the insertion tube to prevent axial or circumferential dislocation of the disposable sputum aspirator.

The bending degree of the tube body 110 is required to be superior to that of the insertion tube 200 so that the tube body 110 can be bent accordingly with the bending of the insertion tube 200 without impeding the normal operation of the insertion tube 200. The bending degree of the tube body 110 is related to factors such as manufacturing materials, dimensions, tube wall thickness and the like of the tube body 110, and in the case of the current disposable sputum aspirator tube, the bending degree of the tube body 110 is better than that of the insertion tube 200 by adjusting the factors, so that the bending degree is easy to realize.

In some extreme cases, misalignment of the tube body 110 and the insertion tube 200 in the axial or circumferential direction may occur, which may exist in the insertion tube 200 being subjected to some extreme morphological changes such as excessive bending or excessive twisting, etc. during operation, which may cause separation of the tube body 110 and the insertion tube 200 at a partial position. For this purpose, one or more buffer segments may be provided on the tube body 110, and the buffer segments may be provided to be uniformly distributed on the tube body 110, and the thickness of the buffer segments may be smaller than that of the rest of the tube body 110, so that stresses at local positions, which may cause misalignment of the tube body 110 and the insertion tube 200 in the axial or circumferential direction, can be released with a minute deformation of the buffer segments.

In this embodiment, the outermost contour of the tube 110 is based on a circle, or other shapes such as an ellipse may be adopted, and the overall structure is substantially cylindrical when the tube 110 is wrapped around the insertion tube 200. The outer wall of the tube body 110 is smoothly transited in the circumferential direction, and preferably, the edges of the end portions of the tube body 110 are rounded.

As shown in fig. 3, one end of the tube body 110, specifically, the end corresponding to the end of the insertion tube 200 in use, is provided with a through hole 150 on the sidewall to facilitate sputum aspiration; as shown in fig. 6, a joint assembly 160 is connected to the other end of the tube body 110, one end of the joint assembly 160 is matched with the shape of the tube body 110 to be suitable for connecting the tube body 110, the other end of the joint assembly 160 is suitable for connecting an external pipeline, such as an external pipeline of a sputum aspirator, and the joint of the end can be in a conventional structure, such as a pagoda head.

Referring to fig. 4, when the tube body 110 and the insertion tube 200 are cooperatively installed, one end of the tube body 110 adjacent to the joint assembly 160 must be separated from the insertion tube 200, and the tube body 110 and the insertion tube 200 may form a bifurcation where the tube body 110 is easily separated, for example, by pulling the tube body 110 toward the distal end of the insertion tube 200, thereby providing a structure capable of binding the two, preferably at the bifurcation.

In this embodiment, the use of the node retention assembly 170 at the bifurcation of the body 110 and the insertion tube 200 makes the body 110 and the insertion tube 200 less prone to separation at the bifurcation, as shown in fig. 7-9. The connection assembly 170 generally has a three-way structure including a first port 171, a second port 172, and a third port 173. The tube 110 is adapted to pass through the first port 171 and out through the second port 172, or through the second port 172 and out through the first port 171, such that a first passageway is provided between the first port 171 and the second port 172 for the tube 110 to pass through. The insertion tube 200 is adapted to pass in from the first port 171 and out from the third port 173, or to pass in from the third port 173 and out from the first port 171, such that there is a second passageway between the first port 171 and the third port 173 through which the insertion tube 200 passes.

One end of the first and second channels has a common port, i.e., first port 171, and the two channels are separated within node-retention assembly 170 and respectively go to second port 172 and third port 173, such that the first and second channels have a common channel on a side of node-retention assembly 170 adjacent first port 171. The size of the common channel is adapted to the outer diameter of the overall structure when the tube body 110 and the insertion tube 200 are connected, and the size of the first channel after passing through the common channel gradually changes to be adapted to the outer diameter of the tube body 110, or the size of the common channel can still be maintained; the channel size of the second channel after passing through the common channel is gradually changed to be adapted to the insertion tube 200, and the channel length of the second channel after passing through the common channel may preferably be set to be slightly longer, which is advantageous in improving the supporting and stabilizing effects of the node-retaining assembly 170.

In this embodiment, the second channel is similar to the fitting channel 130, and is also an open loop structure in the circumferential direction, and has an opening 174. The opening 174 is sized smaller than the outer diameter of the insertion tube 200 and the unitary structure when the tube body 110 and insertion tube 200 are connected allows access from the opening 174 into the corresponding channel of the node-retention assembly 170.

The rigidity of the node-retention assembly 170 is higher than that of the tube body 110 to ensure its support and stability at the bifurcation, while having a certain elasticity or recoverable deformation to enable the insertion tube 200 and the integral structure of the tube body 110 and the insertion tube 200 when connected to enter the corresponding passage of the node-retention assembly 170 from the opening 174. However, the hardness requirement is relatively loose, even though the hardness is relatively high, the connection between the pipe body 110 and the insertion tube 200 can be achieved by corresponding installation methods, for example, the pipe body 110 is first inserted into the node retention assembly 170 from the second port 172 and the end of the pipe body reaches the first port 171, then the insertion tube 200 is inserted into the node retention assembly 170 from the third port 173 and the end of the pipe body 200 reaches the first port 171, at this time, the insertion tube 200 is inserted into the fitting channel 130 of the pipe body 110 in the common channel in the node retention assembly 170, the connection is formed between the two ends, then the node retention assembly 170 is gradually moved away from the end of the insertion tube 200, and in the process, the corresponding part of the pipe body 110 is continuously connected with the corresponding part of the insertion tube 200 until the node retention assembly 170 is moved to the desired position, so that in other embodiments, the second channel of the node retention assembly 170 adopts a closed-loop structure, or the hardness of the node retention assembly 170 itself is relatively high, and the connection between the pipe body 110 and the insertion tube 200 can still be achieved.

The disposable bronchofiberscope matched sputum aspirator of the embodiment expands the functions of the bronchofiberscope without an aspiration channel, and can perform sputum aspiration operation during bronchofiberscope examination; for the bronchofiberscope with the suction channel, the bronchofiberscope can provide a proper and effective suction channel, so that the bronchofiberscope does not need to use the suction channel with the bronchofiberscope, the workload of cleaning and disinfecting the bronchofiberscope is greatly reduced, and meanwhile, the sputum suction tube is disposable, and the occurrence of cross infection is avoided to the greatest extent.

The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
