Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a novel quick-connect terminal interface for carbon dioxide cylinders. Background Technology

[0002] In the operating room, the quick-connect terminal interface of the carbon dioxide supply cylinder is a key component of the centralized medical gas supply system. Its main functions include enabling rapid connection and disconnection of gas, ensuring airtightness, preventing accidental gas connection, adapting to diverse equipment, and facilitating centralized management to avoid delays in the surgical process.

[0003] Among the existing publicly available documents, patent publication number CN220320544U discloses a quick-connect clamp for high-pressure gas cylinders. This technology, through the integrated design of the safety valve and the stainless steel sliding shell, makes the connection more stable when connected to the gas cylinder via the self-locking threaded claw, preventing loosening and thus achieving a quick and stable connection between the gas cylinder and the clamp. However, this patent has the following drawbacks.

[0004] When connecting the connector of a carbon dioxide cylinder to a pipeline, pulling on the pipeline can easily cause the quick-connect terminal interface to be pulled, or even pulled too much, causing the interface to detach from the carbon dioxide cylinder connector, resulting in gas leakage. It is difficult to achieve bidirectional large-area protection after connection, and the interface protection is poor. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a novel quick-connect terminal interface for carbon dioxide cylinders, including a gas pipe connector, wherein a connecting pipe is inserted and connected to the inner wall of the gas pipe connector, and a connecting block is provided above the connecting pipe. One end of the connecting block is provided with a bidirectional limiting component, which is used to limit the insertion pipe in both vertical and tilt directions. The bidirectional limiting component includes: A vertical insert is fixed to the lower surface of the connecting block, and a diagonal bar is fixed to one side of the vertical insert; An inclined sleeve block slides obliquely on the outer wall of an inclined rod. An inclined insert is fixed on one side of the inclined sleeve block, and the inclined insert is used to slide obliquely along the vertical insert.

[0006] In a preferred embodiment, the upper surface of the connecting block is arranged parallel to the upper surface of the vertical insert, and both bottom ends of the vertical insert are rounded.

[0007] In a preferred embodiment, the diagonal bar is inclined and the vertical cross-section of the diagonal bar is circular.

[0008] In a preferred embodiment, a limiting block is fixed at one end of the diagonal bar and away from the vertical insert, and the limiting block is used to limit the movement position of the diagonal sleeve block.

[0009] In a preferred embodiment, one end of the tracheal connector is fixedly connected to a shunt tube, and a connected threaded tube is installed on one side of the outer wall of the shunt tube.

[0010] In a preferred embodiment, two pressure gauges are fixedly connected to the top of the outer wall of the diversion tube, and the two pressure gauges are symmetrically arranged about the middle of the diversion tube.

[0011] In a preferred embodiment, a locking block is slidably connected to the outer wall of the insertion tube, and a spring piece is fixed between the locking block and the tracheal connector, with the locking block and the tracheal connector being slidably connected.

[0012] In a preferred embodiment, a counterweight ring is fixed to the other end of the connecting block, and a guide post is installed on the inner wall of the counterweight ring. The guide post is fixedly connected to the air pipe connector, and the guide post is used to guide the sliding of the counterweight ring. A counterweight is fixed to the upper surface of the connecting block, and the counterweight is used to counterweight the connecting block and the vertical insert.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a bidirectional limiting component, in which the tracheal connector and the insertion tube form a quick-connect connection. The vertical insertion strip limits the vertical position of the insertion tube, and the inclined rod supports the limiting block to limit the position of the inclined sleeve block. The counterweight of the sleeve block moves downward along the outer wall of the inclined rod, and the inclined sleeve block drives the inclined insertion strip to move downward. The inclined insertion strip limits the inclination of the insertion tube, which can achieve bidirectional limiting of the insertion tube in both vertical and inclined positions, avoiding the leakage problem caused by the forced separation of the insertion tube and the tracheal connector. The protection of the connection between the insertion tube and the tracheal connector is more excellent.

[0014] 2. This utility model guides the counterweight ring with a guide post, which provides lateral limiting for the counterweight ring. The counterweight block provides vertical counterweight for the connecting block and the vertical insert, ensuring that the vertical insert stably counterweights and limits the insertion tube, thereby improving the firmness of the connection between the air pipe connector and the insertion tube.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1 - Figure 4 The present invention discloses a novel quick-connect terminal interface for carbon dioxide cylinders. This novel quick-connect terminal interface for carbon dioxide cylinders is equipped with a bidirectional limiting component. The bidirectional limiting component can limit the vertical and inclined positions of the connector 2, preventing the connector 2 from being forcibly separated from the gas pipe connector 1 and causing air leakage. The protection at the connection between the connector 2 and the gas pipe connector 1 is more excellent. The specific structure of the bidirectional limiting component is as follows.

[0022] Example 1: In this embodiment, as Figure 1 - Figure 4 As shown, a novel quick-connect terminal interface for carbon dioxide cylinders includes a gas pipe connector 1, with a connecting pipe 2 inserted into the inner wall of the gas pipe connector 1. A connecting block 3 is located above the connecting pipe 2. One end of the connecting block 3 is equipped with a bidirectional limiting component, which is used to limit the vertical and inclined directions of the connecting pipe 2. The bidirectional limiting component includes: a vertical insert 4, fixed to the lower surface of the connecting block 3, with a diagonal rod 5 fixed to one side of the vertical insert 4; and a diagonal sleeve 6, which slides obliquely on the outer wall of the diagonal rod 5. A diagonal insert 7 is fixed to one inclined surface of the diagonal sleeve 6 and is used to slide obliquely along the vertical insert 4. The upper surface of the connecting block 3 and the upper surface of the vertical insert 4 are parallel, and both bottom ends of the vertical insert 4 are rounded. The diagonal rod 5 is obliquely positioned, and its vertical cross-section is circular.

[0023] In this embodiment, as Figure 3 As shown, a limiting block 8 is fixed at one end of the diagonal rod 5, away from the vertical insert 4, and the limiting block 8 is used to limit the movement of the diagonal sleeve block 6. The limiting block 8 is supported by the diagonal rod 5, so the limiting block 8 limits the position of the diagonal sleeve block 6.

[0024] In this embodiment, as Figure 1 As shown, one end of the endotracheal connector 1 is fixedly connected to a shunt pipe 9, and a connected threaded pipe 10 is installed on one side of the outer wall of the shunt pipe 9. The threaded pipe 10 is threadedly connected to the output end of the carbon dioxide cylinder by rotating the inner thread of the threaded pipe 10, and the shunt pipe 9 and the threaded pipe 10 are in a connected state.

[0025] In this embodiment, as Figure 1 As shown, two pressure gauges 11 are fixedly connected to the top of the outer wall of the diverter tube 9, and the two pressure gauges 11 are symmetrically arranged about the middle of the diverter tube 9. The pressure values ​​of carbon dioxide gas can be viewed through the pressure gauges 11, making it easy to know the pressure value inside the diverter tube 9.

[0026] In this embodiment, as Figure 4 As shown, a locking block 12 is slidably connected to the outer wall of the intubation tube 2, and a spring piece 13 is fixed between the locking block 12 and the tracheal connector 1. The locking block 12 and the tracheal connector 1 are slidably connected. The locking block 12 is moved by the intubation tube 2, and the spring piece 13 is compressed on the inner wall of the tracheal connector 1, locking the locking block 12 onto the outer wall of the intubation tube 2. Finally, the spring piece 13 provides a rebound force to the locking block 12, so that the tracheal connector 1 and the intubation tube 2 are quickly connected.

[0027] In this embodiment, the novel quick-connect terminal interface is installed by rotating the inner thread of the threaded tube 10 to connect with the output end of the carbon dioxide cylinder. The insertion tube 2 moves the locking block 12, which compresses the spring 13. The spring 13 is compressed against the inner wall of the air pipe connector 1, thus locking the locking block 12 onto the outer wall of the insertion tube 2. Finally, the spring 13 provides a rebound force to the locking block 12, thus forming a quick-connect connection between the air pipe connector 1 and the insertion tube 2. The air pipe connector 1 supports the guide post 14, which in turn supports the counterweight ring 15. The counterweight ring 15 supports the connecting block 3, which provides lateral support to the vertical insertion strip 4, and the vertical insertion strip 4 provides vertical support to the insertion tube 2. To prevent the insertion tube 2 from being pulled and forcibly separated from the endotracheal connector 1, the vertical insert 4 supports the diagonal rod 5, and the diagonal rod 5 supports the limiting block 8 to limit the position of the diagonal sleeve block 6. In this way, the counterweight of the diagonal sleeve block 6 moves downward along the outer wall of the diagonal rod 5, which in turn drives the diagonal insert 7 to move downward. The diagonal insert 7 moves downward along the vertical insert 4, and the diagonal insert 7 provides a diagonal limiting treatment for the insertion tube 2. This can achieve bidirectional limiting treatment of the insertion tube 2 in both vertical and diagonal positions, avoiding the forced pulling of the insertion tube 2 and the forced separation of the insertion tube 2 from the endotracheal connector 1, which would cause air leakage. In this way, the insertion tube 2 and the endotracheal connector 1 have better anti-dislodgement performance after quick insertion.

[0028] Carbon dioxide gas is delivered from a carbon dioxide cylinder to a threaded tube 10, then from the threaded tube 10 into a distribution tube 9, and from the distribution tube 9 into a gas connector 1. From the gas connector 1 into a plug tube 2, the gas is discharged through the plug tube 2. The pressure gauge 11 displays the carbon dioxide gas pressure value.

[0029] Example 2: In this embodiment, as Figure 2 As shown, a counterweight ring 15 is fixed to the other end of the connecting block 3, and a guide post 14 is installed on the inner wall of the counterweight ring 15. The guide post 14 is fixedly connected to the air pipe connector 1, and the guide post 14 is used to guide the counterweight ring 15 to slide. A counterweight block 16 is fixed to the upper surface of the connecting block 3. The counterweight block 16 is used to counterweight the connecting block 3 and the vertical insert 4.

[0030] In this embodiment, the novel quick-connect terminal interface for carbon dioxide cylinders uses a guide post 14 supported by a gas pipe connector 1. The guide post 14 guides the counterweight ring 15 and provides lateral limiting for the counterweight ring 15. In this way, the counterweight ring 15 supports the connecting block 3, while the counterweight block 16 provides vertical counterweight to the connecting block 3 and the vertical insertion strip 4, ensuring that the vertical insertion strip 4 stably counterweights and limits the insertion tube 2, thereby improving the firmness of the connection between the gas pipe connector 1 and the insertion tube 2.
