Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multi-purpose connector for a bronchoscope. Background Technology

[0002] Fiberoptic bronchoscopy is suitable for observing lesions in the lobes, segments, and subsegments of the lungs, for biopsy sampling, for bacteriological and cytological examinations, and for radiography, teaching, and dynamic recording when used with a TV system.

[0003] Patent specification CN117530649A discloses a conversion connector for fiberoptic bronchoscopy, comprising a connector body and multiple sampling units. The connector body has a cylindrical fluid-conducting cavity. The multiple sampling units are disposed within the connector body and used to sample sputum flowing within the fluid-conducting cavity. An inlet tube is connected to the top of the connector body and communicates with the fluid-conducting cavity, while an outlet tube is connected to the bottom of the connector body and communicates with the fluid-conducting cavity. The inlet tube is equipped with a connecting mechanism. This device allows for separate collection and culture of sputum from different locations on a patient's body, according to the doctor's treatment needs. The entire operation is simple and convenient in clinical use. By separately collecting sputum from different locations on a patient's body, targeted treatment can be implemented, thereby improving treatment efficacy.

[0004] However, the following problems were found in the implementation of the above-mentioned technical solution: During the use of the above-mentioned device, the suction valve on the fiberoptic bronchoscope is connected to the suction tube collector for sputum suction, collection and culture. However, during the use of the bronchoscope, some patients will experience hypoxia and need to be given oxygen immediately, which requires switching between the bronchoscope and the oxygen supply tube. This is quite troublesome and time-consuming. Moreover, the required length of the tube connected to the bronchoscope varies depending on the working environment. If the tube is too long, it will drag around and affect the surroundings. If it is too short, it will be difficult to reach the patient's position, increasing labor costs. Therefore, further improvements are needed. Utility Model Content

[0005] This invention proposes a multi-purpose tube connector for bronchoscopes, which solves the problems in related technologies, such as the inconvenience of adjusting the relative length of the leaking part of the first silicone tube and the inconvenience of oxygen inhalation and sputum collection while using the bronchoscope body.

[0006] The technical solution of this utility model is as follows:

[0007] A multi-purpose connector for a bronchoscope includes a bronchoscope body. An interface is fixedly connected to one side of the bronchoscope body. A control switch is provided on the outer surface of the interface. A connector assembly is provided on one side of the interface. The connector assembly includes a connector component disposed on one side of the interface for connecting to the interface in the bronchoscope body. A connecting component is provided on the outer surface of one side of the connector component for controlling the length of the protruding part of the connector component, i.e., changing the length of the connector component. One end of the connecting component is provided with a tee component for quickly performing multiple purposes via the interface on the bronchoscope body.

[0013] Preferably, the inner wall of the second silicone tube is in contact with the outer surface of the sealing ring.

[0014] Preferably, the bolt passes through the inside of the through groove and is threadedly connected to the threaded groove.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. This utility model separates the bolt from the threaded groove by rotating it, and then pulls the connecting ring to slide along the outer surface of the first silicone tube. When the protruding part of the first silicone tube is adjusted to a suitable length, the operator aligns the through groove of the connecting ring with the corresponding threaded groove of the protruding part of the first silicone tube. At this time, the bolt can be threaded through the inside of the through groove and fixedly connected to the threaded groove. This prevents the connecting ring from sliding along the outer surface of the first silicone tube again. The presence of the sealing ring seals the gap between the first and second silicone tubes, preventing gas and liquid from leaking out from the connection gap between the first and second silicone tubes. This solves the problem of inconvenience in adjusting the relative length of the protruding part of the first silicone tube.

[0017] 2. The presence of the first and second pipes in this utility model allows the bronchoscope to be used with oxygen via the oxygen inhalation tube connected to the first pipe, and to collect sputum via the suction device and negative pressure suction tube connected to the second pipe. This makes it convenient and easy for staff to use, and solves the problem that it is inconvenient to perform oxygen inhalation and sputum collection while using the bronchoscope.

A three-way component 33 is disposed at one end of the connecting component 32 for enabling the bronchoscope body 1 to be used for various purposes quickly via the interface 2. A bolt 34 is threaded through the outer surface of the connecting component 32 for fixing the connecting component 32 and the connector component 31. The bolt 34 passes through the inside of the through groove 3211 and is threadedly connected to the threaded groove 3121.

[0028] like Figure 3 As shown, the connector component 31 includes a connector ring 311 disposed on the outer surface of the outer end of the interface 2. One end of the connector ring 311 is fixedly connected to a first silicone tube 312. The upper end of the first silicone tube 312 has evenly spaced threaded grooves 3121. A first blocking ring 3122 is fixedly connected to the outer surface of the end of the first silicone tube 312 away from the connector ring 311. A sealing ring 31221 is fixedly connected to the outer surface of the first blocking ring 3122. The connector ring 311 is used to connect with the interface 2, so that the connector ring 311 can be connected to the bronchoscope body 1 through the interface 2. The threaded groove 3121 is a positioning groove of different lengths at the protruding end of the first silicone tube 312. The first blocking ring 3122 is used to prevent the first silicone tube 312 from detaching from the interior of the connecting ring 321. The sealing ring 31221 is used to prevent gaps between the first silicone tube 312 and the second silicone tube 331.

[0029] like Figure 4As shown, the connecting component 32 includes a connecting ring 321 slidably connected to the outer surface of the first silicone tube 312. A through groove 3211 is formed through the outer surface of the connecting ring 321. A second blocking ring 3212 is fixedly connected to the inner wall of one end of the connecting ring 321. The through groove 3211 is connected to the threaded groove 3121. The second blocking ring 3212 is attached to the outer surface of the first silicone tube 312. The through groove 3211 is used to cooperate with the threaded groove 3121 to control the length of the protruding part of the first silicone tube 312, that is, to adjust the relative length of the first silicone tube 312.

[0030] like Figure 5 As shown, the three-way component 33 includes a second silicone tube 331 fixedly connected to one end of the connecting ring 321. A third blocking ring 3311 is fixedly connected to the inner wall of one end of the second silicone tube 331. A first pipe 3312 and a second pipe 3313 are connected to the outer surface of the other end of the second silicone tube 331.

A negative pressure suction tube is connected to the second pipe 3313 or a sputum collector is connected to a negative pressure suction tube. The inner wall of the second silicone tube 331 is in contact with the outer surface of the sealing ring 31221. The third blocking ring 3311 is used to cooperate with the first blocking ring 3122 to prevent the first silicone tube 312 from detaching from the interior of the second silicone tube 331. The control switch 21 is used to control the opening and closing state of the first pipe 3312 and the second pipe 3313.

[0031] The working principle and usage instructions of this utility model are as follows: When it is necessary to adjust the relative length of the exposed part of the first silicone tube 312, that is, to adjust the overall length of the connector assembly 3, the operator first needs to rotate the bolt 34 to separate it from the threaded groove 3121. Then, pull the connecting ring 321 to slide along the outer surface of the first silicone tube 312. When the exposed part of the first silicone tube 312 is adjusted to a suitable length, the operator aligns the through groove 3211 of the connecting ring 321 with the threaded groove 3121 at the corresponding position of the exposed part of the first silicone tube 312. At this time, the bolt 34 can be threaded through the inside of the through groove 3211 and fixedly connected to the threaded groove 3121. This will prevent the connecting ring 321 from sliding along the outer surface of the first silicone tube 312 again. The presence of the sealing ring 31221 will seal the gap between the first silicone tube 312 and the second silicone tube 331 to prevent gas and liquid from leaking out from the connection gap between the first silicone tube 312 and the second silicone tube 331.

[0032] Furthermore, due to the presence of the first tube 3312 and the second tube 3313, the bronchoscope body 1 can be used to receive oxygen through the oxygen inhalation tube connected to the first tube 3312, and sputum can be collected through the suction device and negative pressure suction tube connected to the second tube 3313, making it convenient and easy for staff to use.
