[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] The applicant has discovered that the interface is prone to loosening or even detachment due to patient activity, changes in body position, or interference from medical procedures. This not only interrupts the continuous gas supply and leads to treatment interruption, but may also affect the ventilator's precise control of the patient's respiratory status due to gas leakage. Therefore, how to solve the problems of easy detachment and inconvenient operation of existing connection devices is an urgent problem to be solved in the field of ventilator circuit and ventilator interface connection.

[0035] In view of this, in order to solve the above problems, the applicant proposes a breathing circuit safety locking device. Please see below. Figure 1 , Figure 1 This is a partial exploded view of a breathing circuit safety locking device provided in an embodiment of this application; the breathing circuit safety locking device includes: a connecting pipe 902, a support plate 4, a locking component 1, an elastic bracket 2, a thumb pressure plate 5, a second connecting rod 6, and an interface 903.

[0036] The connecting tube 902 has a first groove 9021 at one end, a support plate 4 is located at the end of the connecting tube 902 near the first groove 9021, a locking component 1 is located inside the connecting tube 902, an elastic bracket 2 is connected to the locking component 1, one end of the thumb pressure plate 5 is connected to the support plate 4, the other end of the thumb pressure plate 5 has a second groove 501, a second connecting rod 6 is rotatably connected to the thumb pressure plate 5, and an interface 903 is connected to the connecting tube 902.

[0037] The above-mentioned components, including the locking mechanism 1, thumb pressure plate 5, second connecting rod 6, and interface 903, ensure a stable and reliable connection between the breathing circuit and the ventilator interface 903, effectively mitigating the risk of connection detachment and thus guaranteeing patient safety. Through the precise cooperation between the elastic support 2 and the locking mechanism 1, the device automatically and quickly resets to its initial state after each operation, providing a stable and consistent starting point for subsequent connection operations. This design not only improves connection stability but also greatly simplifies the operational process, enhancing safety and efficiency in medical practice.

[0038] In this embodiment, a first connecting rod 3 may also be included. The first connecting rod 3 may be a rod-shaped structure, with one end connected to the locking component 1 to ensure the effective transmission of operating force. The other end of the first connecting rod 3 is connected to the thumb pressure plate 5 through the second connecting rod 6.

[0039] See Figure 3 As shown, Figure 3 This is a schematic diagram of the external structure of a breathing circuit safety locking device provided in an embodiment of this application. Furthermore, the breathing circuit safety locking device may also include a sealing component 7, a sleeve 8, and a connector 10. One end of the sleeve 8 is connected to the sealing component, ensuring the sealing and stability of the passage. The connector 10 is fitted onto the other end of the sleeve 8, simplifying the installation process and enhancing the connection's strength. The sleeve 8, the sealing component, and the connector 10 form a passage, providing strong assurance for the smooth transmission of gas.

[0040] The ventilation assembly 9 may include a breathing channel 901, a connecting tube 902, and an interface 903. The connecting tube 902 may be a threaded hose, which connects to the side wall of the cannula 8 via the breathing channel 901 and is internally connected, avoiding gas leakage due to loose connections. The threaded connection design also allows medical personnel to easily disassemble and replace the connecting tube 902, improving maintenance efficiency and convenience. The other end of the threaded hose, away from the breathing channel 901, connects to the interface 903, ensuring smooth airflow into and out of the patient's respiratory system.

[0041] To increase grip stability, the surface of the thumb pressure plate 5 can also be provided with anti-slip texture. The anti-slip texture is evenly distributed on the surface of the thumb pressure plate 5, effectively increasing the friction between the thumb pressure plate 5 and the fingers. When medical personnel press the thumb pressure plate 5 with their thumb, the anti-slip texture can firmly grip the fingers, preventing slippage due to sweaty hands or careless operation. The anti-slip texture not only improves the stability of operation, but also greatly enhances the confidence of medical personnel, enabling them to complete the pressing operation more calmly and accurately.

[0042] Additionally, refer to Figure 3 On the outer side of the connector 10, a grip 1017 is specially designed. This grip 1017 not only provides the user with a stable grip point, but also cleverly incorporates several anti-slip grooves. The presence of these anti-slip grooves 7 greatly increases the friction between the user's hand and the grip 101, ensuring that the user can easily and stably grip the connector 10 even in wet or oily environments. The main function of the grip 101 is to facilitate the user in unscrewing the connector 10, whether for connection or disassembly operations.

[0043] In view of this, the support plate 4 is located at one end of the connecting tube 902 near the first groove 9021. The support plate 4 provides a stable support platform for components such as the locking component 1, the elastic bracket 2, and the thumb pressure plate 5. The support plate 4 can be made of high-strength material to ensure its load-bearing capacity and stability, and to maintain its shape and performance even during long-term use. With the stable support of the support plate 4, the locking component 1 can more accurately engage with the first groove 9021 on the connecting tube 902 to achieve a tight lock; the elastic bracket 2 can flexibly spring under the pressure of the thumb pressure plate 5, providing sufficient power for unlocking the locking component 1; and the thumb pressure plate 5 can be stably placed on the support plate 4, facilitating precise operation by medical personnel.

[0044] The sealing device 7 may include a sealing cap 701 and a sealing plug 702. One end of the sealing plug 702 is located inside the sealing cap 701. The sealing cap 701, as a crucial component, offers flexibility in material selection. It can be made of either silicone rubber or polyurethane. Silicone rubber is known for its excellent high and low temperature resistance, good flexibility, and sealing properties, ensuring that the sealing cap 701 maintains stable performance in various environments. Polyurethane, on the other hand, possesses high strength, wear resistance, and excellent elasticity, allowing the sealing cap 701 to withstand greater pressure and friction during use, thus extending its service life.

[0045] Working principle: During operation, when the thumb pressure plate 5 is pressed by an external force, it rotates around its connection point with the support plate 4. This rotation drives the second connecting rod 6 and the connected first connecting rod 3 to move in a coordinated manner. As the first connecting rod 3 moves, the locking component 1 is smoothly guided to move upward within the connecting tube 902. During this process, the elastic support 2 deforms due to compression and accumulates elastic potential energy, preparing for the subsequent reset action.

[0046] At this point, the medical personnel insert the ventilator interface 903 into the preset position. The ventilator interface 903 then engages tightly with the locking component 1, achieving a secure snap-fit ​​connection and ensuring that the ventilator interface 903 can be firmly mounted on the connecting tube 902 and will not easily fall off due to external factors.

[0047] When it is necessary to remove the ventilator interface 903 or perform a reset operation, medical personnel simply need to unplug the ventilator interface 903. This action releases the constraint on the locking component 1, allowing the elastic support 2 to immediately release the previously stored elastic potential energy. This energy propels the locking component 1 to descend quickly and smoothly back to its original position. At the same time, the thumb pressure plate 5 also automatically returns to its initial state under the action of elastic force, and the entire system returns to standby mode, ready for the next operation.
