Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a tracheal connector and an endoscope cleaning and disinfection machine using the same. Background Technology

[0002] In the medical field, high-end equipment such as ventilators and anesthesia machines rely on a supply of highly clean compressed air to ensure safe operation. Because medical air systems are constantly exposed to polluted environments such as humidity and oil, the air filter's inlet and outlet must be connected to a connecting channel via a tubing connector. This allows the air filter to trap particulate matter and block microorganisms within the connecting channel, thus completing gas filtration and purification.

[0003] However, air filter elements have a limited lifespan and need to be replaced periodically. Traditional filter replacement methods present significant technical challenges: traditional air hose connectors generally use threaded sealing structures, which are prone to aging of the sealing rings and stripping of the threads after prolonged use, increasing the risk of gas leaks and directly affecting the stability of the equipment's air supply system. Statistics show that improper connector maintenance accounts for 23% of equipment downtime incidents in medical institutions. Furthermore, traditional threaded connections require specialized tools for disassembly and assembly, resulting in lengthy maintenance times and significantly reducing equipment efficiency. Utility Model Content

[0012] The pressing card and the linkage card are linked by the positive cross-linking structure, which is used to drive the card slot to insert into the annular card slot.

[0013] When the male plug is inserted into the female socket, the male plug drives the linkage member to slide along the axial direction of the female socket, and the pressing member slides along the radial direction of the female socket through the linkage of the positive linkage structure, thereby inserting the bayonet into the annular slot.

[0014] When the male plug is detached from the female socket, the pressing clip slides radially along the female socket, thereby disengaging the latch from the annular slot.

[0015] Preferably, the outer wall of the male plug is provided with an annular boss along the circumference, and the outer circumference of the male plug is divided into a mating section and an installation section by the annular boss. The mating section of the male plug is provided with the annular groove.

[0016] When the male plug is inserted into the female socket, the male plug and the female socket are coaxially arranged.

[0017] Preferably, the pressing mechanism also has a linkage port, and the port and the linkage port are on the same horizontal plane;

[0018] The linkage component has a sloping protrusion, which moves through the linkage opening to form a wedge-shaped transmission engagement with the pressing component.

[0020] The first sliding groove is located near the connection port of the female socket, and the pressing clip is slidably mounted on the first sliding groove. The pressing clip moves along the first sliding groove under the action of the first reset spring.

[0022] Preferably, the pressing mechanism includes a sliding plate and a pressing plate, wherein the sliding plate and the pressing plate are arranged perpendicularly;

[0023] The sliding plate is slidably installed in the first sliding groove, and the sliding plate has the bayonet and the linkage port;

[0026] The linkage component is also provided with a fixing protrusion and a pressing protrusion, and the fixing protrusion, the inclined protrusion and the pressing protrusion are connected in sequence.

[0027] The fixed protrusion is sleeved with the second return spring, and the inclined protrusion is movably inserted into the first or second pin opening. The outer diameter of the inclined protrusion gradually increases from the end connected to the pressing protrusion to the end connected to the fixed protrusion. The outer diameters of both the fixed protrusion and the pressing protrusion are larger than the inner diameter of the first pin opening. The pressing protrusion is used to abut against the male plug.

[0028] Preferably, a male valve core is slidably mounted inside the male plug along its axial direction, and a male return spring is sleeved on the male valve core;

[0029] The female end socket has a female end valve core that is slidably installed inside it along its axial direction, and the female end valve core is fitted with a female end return spring.

[0032] The air filter has an air inlet and an air outlet. The air inlet and the air outlet are connected to an air inlet pipe and an air outlet pipe respectively through the air pipe connector. The other end of the air inlet pipe is connected to the air compression module, and a dryer is installed on the air inlet pipe. The dryer contains a desiccant.

[0033] One of the above technical solutions has the following beneficial effects:

This greatly improves efficiency compared to traditional threaded connections and eliminates the need for external tools, breaking through the operational limitations of compact medical equipment spaces.

[0035] 2. Dynamic reliability: The limiting fit between the bayonet and the annular groove forms a limiting mechanism, which is more reliable than threaded connections, thereby reducing the airtightness leakage rate;

[0036] 3. Anti-accidental self-locking mechanism: Under normal conditions, the mutual limiting design of the pressing card and the linkage card prevents accidental unlocking.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] A tracheal connector includes a male plug 1 and a female socket 2 that are plugged into each other, and a linkage connection component 3 is provided at the connection port of the female socket 2.

[0051] The outer wall of the male plug 1 is provided with an annular groove 11 along the circumference;

[0052] The linkage connection component 3 includes a pressing latch 31, a linkage latch 32, and a positive linkage structure 33;

[0053] The pressing clip 31 is slidably installed along the radial direction of the female socket 2. The pressing clip 31 has a slot 311, and the connection port of the female socket 2 and the slot 311 are available for the male plug 1 to be inserted.

[0054] The linkage card 32 is slidably installed along the axial direction of the female socket 2;

[0055] The pressing card 31 and the linkage card 32 are linked by the positive cross-linking structure 33, which is used to drive the card slot 311 to be inserted into the annular card slot 11.

[0056] When the male plug 1 is inserted into the female socket 2, the male plug 1 drives the linkage member 32 to slide along the axial direction of the female socket 2, and the pressing member 31 slides along the radial direction of the female socket 2 through the linkage of the positive linkage structure 33, so that the bayonet 311 is inserted into the annular slot 11.

[0057] When the male plug 1 is detached from the female socket 2, the pressing clip 31 is pressed and slides radially along the female socket 2, thereby causing the latch 311 to disengage from the annular slot 11.

[0058] This endotracheal connector enables quick, tool-free assembly and disassembly between the male plug 1 and the female socket 2 via a linkage connection component 3. The specific working principle is as follows:

[0059] When the female socket 2 is not in its normal installed state, the pressing clip 31 and the linkage clip 32 restrict each other from sliding.

[0060] When the male plug 1 is inserted into the female socket 2, the connection port of the male plug 1 passes through the bayonet 311 and the connection port of the female socket 2 in sequence. The male plug 1 abuts against and pushes the linkage card 32 to slide along the axial direction of the female socket 2. At the same time, under the linkage action of the positive linkage structure 33, the pressing card 31 is triggered to move radially along the female socket 2. The movement of the pressing card 31 is used to insert part of the edge of the bayonet 311 into the annular slot 11 to form a limit.

[0061] When the male plug 1 is removed from the female socket 2, the pressing clip 31 is manually pressed to push it to slide radially along the female socket 2, so that part of the edge of the latch 311 moves away from the annular groove 11, and the latch 311 is removed from restricting the annular groove 11. At the same time, under the linkage of the positive linkage structure 33, the linkage clip 32 is triggered to slide axially along the female socket 2, so that the pressing clip 31 and the linkage clip 32 gradually restrict each other to slide, and the female socket 2 returns to its uninstalled state.

[0062] Throughout the process, the pressing clip 31 and the linkage clip 32 are converted into axial displacement → radial displacement → axial self-locking through the movement of the positive cross-linking structure 33, replacing the traditional threaded connection. This creates radial restriction between the male plug 1 and the female socket 2, eliminating the risk of aging of the sealing ring 8 and stripping of the threads.

[0063] In summary, the beneficial effects of this endotracheal connector include:

[0064] 1. Tool-free quick disassembly and assembly: The filter replacement operation can be completed manually by pressing the pressing operation of the pressing piece 31 and the orthogonal sliding cooperation of the linkage piece 32. This greatly improves efficiency compared to the traditional threaded connection and does not require external tools, breaking through the operation limitations of the compact space of medical equipment.

[0065] 2. Dynamic reliability: The limiting fit between the bayonet 311 and the annular groove 11 forms a limiting position, which is more reliable than the threaded connection, thereby reducing the airtightness leakage rate;

[0066] 3. Anti-accidental self-locking mechanism: Under normal conditions, the mutual limiting design of the pressing card 31 and the linkage card 32 avoids accidental unlocking. When unlocking, the axial reset stroke of the linkage card 32 needs to be manually pressed to prevent accidental disengagement caused by incomplete locking after maintenance.

[0067] To further explain, the outer wall of the male plug 1 is provided with an annular boss 12 along the circumference. The outer circumference of the male plug 1 is divided into a mating section and an installation section by the annular boss 12. The mating section of the male plug 1 is provided with the annular groove 11.

[0068] When the male plug 1 is inserted into the female socket 2, the male plug 1 and the female socket 2 are coaxially arranged. The linkage cam 32 abuts against the annular boss 12 and slides along the axial direction of the female socket 2 until the connection port of the female socket 2 abuts against the annular boss 12 and stops sliding axially.

[0069] like Figure 2As shown, this endotracheal connector utilizes the engagement of the annular protrusion 12 and the annular groove 11 on the male plug 1 to achieve precise axial positioning with the female socket 2. Simultaneously, the linkage connection component 3 ensures reliable connection: when the mating section of the male plug 1 is inserted into the female socket 2, the linkage component 32 abuts against the annular protrusion 12 before the female socket 2, allowing it to slide axially along the female socket 2. Simultaneously, under the linkage of the positive linkage structure 33, the pressing component 31 is triggered to move radially along the female socket 2. When the connection port of the female socket 2 abuts against the annular protrusion 12, the linkage component 32 and the pressing component 31 stop moving synchronously, at which point the edge of the locking slot 311 is inserted into the annular groove 11.

[0070] Furthermore, the pressing latch 31 is also provided with a linkage port 312, and the latch 311 and the linkage port 312 are on the same horizontal plane;

[0071] The linkage latch 32 is provided with a sloping protrusion 322, which is movably inserted into the linkage port 312, so that the linkage latch 32 and the pressing latch 31 form a wedge-shaped transmission engagement.

[0072] Specifically, the wedge-shaped transmission function of the inclined protrusion 322 and the linkage port 312 is similar to the linkage function of the positive cross-linking structure 33. Both are designed to provide dual protection for the linkage between the linkage latch 32 and the pressing latch 31. Figure 5-6 As shown.

[0073] To further explain, the positive cross-linking dynamic structure 33 includes a first sliding groove 331, a second sliding groove 332, a first return spring 333, and a second return spring 334;

[0074] The first sliding groove 331 is located near the connection port of the female socket 2. The pressing clip 31 is slidably installed on the first sliding groove 331. The pressing clip 31 is guided to move along the first sliding groove 331 under the action of the first reset spring 333.

[0075] The second sliding groove 332 is provided on the outer wall of the female end socket 2. The linkage member 32 is slidably installed in the second sliding groove 332. The linkage member 32 moves along the second sliding groove 332 under the action of the second return spring 334.

[0076] like Figure 2 As shown, when the female socket 2 is not in its normal state of non-installation, the pressing clip 31 and the linkage clip 32 restrict each other from sliding, wherein the first return spring 333 is compressed and stores energy.

[0077] like Figure 4As shown, when the male plug 1 is inserted into the female socket 2, it first contacts the end of the linkage clip 32 where the second return spring 334 is not installed, pushing the linkage clip 32 to retract axially along the second sliding groove 332, and the second return spring 334 is compressed and stores energy. During the retraction of the linkage clip 32, its inclined protrusion 322 and the linkage port 312 of the pressing clip 31 form a wedge-shaped transmission. At this time, the first return spring 333 gradually releases the stored energy, driving the pressing clip 31 to move radially along the first sliding groove 331 until part of the edge of the locking port 311 of the pressing clip 31 is inserted into the annular locking groove 11, thus forming a limit.

[0078] When the male plug 1 is disassembled from the female socket 2, firstly, manually press the pressing clip 31 to overcome the preload of the first return spring 333, compressing the first return spring 333. The pressing clip 31 then retracts radially along the first sliding groove 331, releasing the locking position of the latch 311 on the annular groove 11, allowing the male plug 1 to be pulled out. During the pressing process, the linkage port 312 drives the linkage clip 32 to return axially along the second sliding groove 332 via the inclined protrusion 322. At this time, the second return spring 334 releases its stored energy until the inclined protrusion 322 completely locks the linkage port 312, thereby gradually restricting the sliding of the pressing clip 31 and the linkage clip 32, restoring them to their normal state.

[0079] To further explain, the pressing mechanism 31 includes a sliding plate 313 and a pressing plate 314, which are arranged vertically.

[0080] The sliding plate 313 is slidably mounted on the first sliding groove 331, and the sliding plate 313 has the bayonet 311 and the linkage port 312.

[0081] The first reset spring 333 is installed between the pressing plate 314 and the outer wall of the female socket 2.

[0082] like Figure 1-4 As shown, by utilizing the vertical design of the sliding plate 313 and the pressing plate 314, combined with the elastic preload of the first reset spring 333, the sliding plate 313 is able to move along the guide of the first sliding groove 331, while also providing a convenient pressing operation for the pressing plate 314 during unlocking, thus reducing structural interference.

[0083] To further explain, the linkage port 312 includes a first pin port 3121 and a second pin port 3122. The first pin port 3121 is located between the second pin port 3122 and the bayonet 311, and the first pin port 3121 and the bayonet 311 are partially overlapped. The first pin port 3121 and the second pin port 3122 are also partially overlapped. The inner diameter of the first pin port 3121 is larger than the inner diameter of the second pin port 3122.

[0084] The linkage component 32 is also provided with a fixing protrusion 321 and a pressing protrusion 323, and the fixing protrusion 321, the inclined protrusion 322 and the pressing protrusion 323 are connected in sequence.

[0085] The fixed protrusion 321 is sleeved with the second return spring 334. The inclined protrusion 322 is movably inserted into the first pin opening 3121 or the second pin opening 3122. The outer diameter of the inclined protrusion 322 gradually increases from the end connected to the pressing protrusion 323 to the end connected to the fixed protrusion 321. The outer diameters of both the fixed protrusion 321 and the pressing protrusion 323 are larger than the inner diameter of the first pin opening 3121. The pressing protrusion 323 is used to abut against the male plug 1.

[0086] like Figure 5-6 As shown, under normal conditions, one end of the inclined protrusion 322 with a larger outer diameter is installed in the first pin hole 3121 with a larger inner diameter, thereby restricting the sliding of the pressing latch 31 and the linkage latch 32.

[0087] When the male plug 1 is inserted into the female socket 2, the male plug 1 abuts against the pressing protrusion 323 of the linkage clip 32, pushing the linkage clip 32 to move axially backward along the second sliding groove 332. Since the inclined protrusion 322 has a gradually changing outer diameter structure, as the male plug 1 continues to be inserted, the end with the smaller outer diameter of the inclined protrusion 322 gradually moves to be installed in the second pin hole 3122 with a smaller inner diameter. At the same time, the pressing clip 31 also moves radially along the first sliding groove 331 under the action of the first return spring 333 gradually releasing the stored energy, until the connection port of the female socket 2 abuts against the annular protrusion 12 of the male plug 1. When the male plug 1 can no longer be inserted, the locking slot 311 of the pressing clip 31 has been locked into the annular locking groove 11, and the installation is completed.

[0088] When the male plug 1 is disassembled from the female socket 2, the pressing plate 314 is pressed manually. The sliding plate 313 overcomes the resistance of the first return spring 333 and returns to its radial position. The locking slot 311 disengages from the annular slot 11. During the pressing process, the inclined protrusion 322 of the linkage locking member 32 gradually moves from the second pin port 3122 with a smaller inner diameter to the first pin port 3121 with a larger inner diameter until it is completely locked in the first pin port 3121. Thus, the pressing locking member 31 and the linkage locking member 32 gradually restrict each other from sliding and return to normal.

[0089] To further explain, a male valve core 4 is slidably installed inside the male plug 1 along its axial direction, and a male return spring 5 is sleeved on the male valve core 4;

[0090] The female end socket 2 has a female end valve core 6 that is slidably installed inside it along its axial direction, and the female end valve core 6 is fitted with a female end return spring 7.

[0091] like Figure 4 As shown, when the male plug 1 is inserted into the female socket 2, the male valve core 4 and the female valve core 6 mate, and they move axially against the preload of the male return spring 5 and the female return spring 7, respectively. After the linkage connection assembly 3 presses the locking piece 31 and the linkage locking piece 32 into the annular groove 11 of the male plug 1 to complete the mechanical locking, the male valve core 4 and the female valve core 6 open synchronously, forming a complete airflow passage.

[0092] When the male plug 1 is disconnected from the female socket 2, the male return spring 5 instantaneously releases its stored energy, pushing the male valve core 4 to reset and close, thus closing the male air passage; simultaneously, the female return spring 7 pushes the female valve core 6 to reset, closing the female air passage. Figure 2 As shown.

[0093] To further explain, the male plug 1 is fitted with a sealing ring 8 on its mating section, and the inner wall of the female socket 2 is provided with a sealing groove 9 that is adapted to the sealing ring 8.

[0094] like Figure 4 As shown, when the male plug 1 is inserted into the female socket 2, the O-ring 8 of the mating section is radially compressed by the sealing groove 9, generating contact pressure to form an axial surface contact seal. At the same time, the connection port surface of the female socket 2 abuts against the annular boss 12, forming a double-stage seal in both axial and radial directions, which prevents gas leakage when the male valve core 4 and the female valve core 6 are vented.

[0095] A tracheal endoscope cleaning and disinfection machine 10 includes an air compression module 101, an air filter 102, and a tracheal connector 103 as described above.

[0096] The air filter 101 has an air inlet and an air outlet. The air inlet and the air outlet are connected to the air inlet pipe 104 and the air outlet pipe respectively through the air pipe connector 103. The other end of the air inlet pipe 104 is connected to the air compression module 101, and a dryer 105 is installed on the air inlet pipe 104. The dryer 105 contains a desiccant.

[0097] Specifically, such as Figure 7-8 As shown, the air compression module 101 compresses the air to a pressure of approximately 120 kPa, then passes the compressed air through the intake pipe 104 and through the desiccant in the dryer 105 for dehydration treatment, and finally sends it to the filter element in the air filter 102 for filtration and then sends out clean air through the outlet pipe of the air outlet.

[0098] When the filter element inside the air filter 101 needs to be replaced, simply press the pressing clip 31 manually to retract it radially along the female socket 2, releasing the restriction of the annular groove 11 of the male plug 1 by the latch 311, and the male plug 1 can be pulled out from the female socket 2.

[0099] When reinstalling the intake pipe 104 after replacing the filter element, simply insert the male plug 1 into the female socket 2 until the connection port of the female socket 2 abuts against the annular protrusion 12 of the male plug 1. When the male plug 1 can no longer be inserted, the locking slot 311 of the pressing clip 31 is engaged with the annular groove 11, thus completing the installation.

[0100] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
