[0035] The telescopic anesthesia circuit of the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1 to 4 As shown, the telescopic anesthesia circuit provided in the embodiment of the utility model includes a tube body 10, an interface part 20 and a locking mechanism 30. The tube body 10 is constructed to be switchable to a stretched state or a compressed state along the length direction; the interface part 20 is arranged on the tube body 10, and is suitable for detachable connection with the breathing part; the locking mechanism 30 is arranged in the interface part 20, and when the interface part 20 and the breathing part are connected to each other, the locking mechanism 30 locks and fixes the breathing part and the interface part 20.

[0037] Among them, the breathing piece may include a breathing mask or a tracheal tube, one end of the tube body 10 can be connected to the anesthesia machine, and the interface part 20 can be fixed to the breathing piece, so that the anesthesia machine can deliver anesthetics and fresh air through the breathing piece to the patient's respiratory tract through the tube body 10, and discharge the patient's exhaled gas through the tube body 10.

[0038] The telescopic anesthesia circuit provided by the utility model can switch the tube body 10 to a stretched state or a compressed state according to different needs, so that the length of the tube body 10 can be changed to meet different ventilation volumes, and the interface component 20 and the breathing component are locked and fixed by the locking mechanism 30, which can ensure that the breathing component has better stability during use.

[0039] Reference Figure 2 and Figure 3 As shown, the tube body 10 has an expiratory circuit 101 and an inspiratory circuit 102, one end of the expiratory circuit 101 and the inspiratory circuit 102 are commonly connected to the anesthesia machine, and the other end is commonly connected to the interface component 20; further, the interface component 20 has at least two branch interfaces 201 and at least one connecting interface 202, at least two branch interfaces 201 are respectively connected to the expiratory circuit 101 and the inspiratory circuit 102, and at least one connecting interface 202 is detachably connected to the respiratory component.

[0040] In this embodiment, when in use, anesthetics and fresh air can be delivered to the patient's respiratory tract through the inhalation line 102, and the gas exhaled by the patient can be discharged through the exhalation line 101. By switching the exhalation line 101 and the inhalation line 102 to a stretched state, the overall ventilation volume can be increased. By switching the exhalation line 101 and the inhalation line 102 to a compressed state, the overall ventilation volume can be reduced, making it more convenient to use under different needs. It can be understood that the detachable connection with the respiratory component through the connection interface 202 makes it more convenient and simpler to install or disassemble the respiratory component.

[0041] Reference Figure 3 and Figure 4 As shown, the locking mechanism 30 includes a first elastic member 31 and a locking ball 32 . The first elastic member 31 is disposed in the connection interface 202 ; the locking ball 32 is disposed at the end of the first elastic member 31 and protrudes from the inner circumference of the connection interface 202 .

[0042] In this embodiment, the respiratory part interface P10 can be plugged into the connecting interface 202, and a groove compatible with the locking mechanism 30 can be set on the outer peripheral surface of the respiratory part interface P10, so that when the respiratory part interface P10 is plugged into the connecting interface 202, the respiratory part interface P10 can push the locking ball 32 to be compressed toward the first elastic part 31, and when the groove corresponds to the locking ball 32, the first elastic part 31 can push the locking ball 32 to engage in the groove, thereby locking and fixing the respiratory part interface P10 and the connecting interface 202 to ensure better overall stability.

[0043] Furthermore, the inner circumference of the connection interface 202 has a sealing ring 204, and the sealing ring 204 is used to seal the gap between the respiratory component and the connection interface 202. When the connection interface 202 is fixed to the respiratory component interface P10, the gap between the connection interface 202 and the respiratory component interface P10 can be closed by the sealing ring 204, so that the overall sealing effect is better.

[0044] Specifically, it also includes an opening and closing component 40, which is arranged in the connection interface 202. When the respiratory component and the interface component 20 are connected to each other, the opening and closing component 40 is opened and forces the respiratory component and the interface component 20 to communicate with each other; when the respiratory component and the interface component 20 are separated from each other, the opening and closing component 40 closes the interface component 20; further, the opening and closing component 40 includes a second elastic component 41 and an opening and closing component 42, and the second elastic component 41 is arranged in the connection interface 202; the opening and closing component 42 is connected to the second elastic component 41, and when the respiratory component and the interface component 20 are connected to each other, the opening and closing component 42 is opened to force the respiratory component and the interface component 20 to communicate with each other.

[0045] In this embodiment, a stopper 203 is provided in the connection interface 202 and is away from the second elastic member 41, and the opening and closing member 42 is slidably connected to the stopper 203. One end of the opening and closing member 42 is connected to the second elastic member 41, and the other end is slidably connected to the stopper 203 and extends to the side of the stopper 203 away from the closing member 42. When the respiratory member interface P10 is plugged into the connection interface 202, the respiratory member interface P10 can push the opening and closing member 42 and the stopper 203 away from each other, and at the same time, the locking ball 32 locks the respiratory member interface P10. When the breathing part interface P10 and the connecting interface 202 are disassembled from each other, the second elastic member 41 pushes the opening and closing member 42 to move toward the stopper 203, so that the stopper 203 is closed by the opening and closing member 42, thereby reducing the entry of external germs into the tube body 10 and improving the overall safety and reliability.

[0046] It can be understood that the stopper 203 has a first through hole 2031, the opening and closing member 42 has a second through hole 421, the first through hole 2031 and the second through hole 421 are offset from each other, and when the breathing member and the interface member 20 are connected to each other, the first through hole 2031 and the second through hole 421 are connected to each other.

[0047] In this embodiment, when the opening and closing member 42 and the stopper 203 are away from each other, the first through hole 2031 and the second through hole 421 are connected to each other. When the opening and closing member 42 and the stopper 203 are close to each other, the opening and closing member 42 closes the first through hole 2031 and the stopper 203 closes the second through hole 421, thereby reducing the entry of external germs into the tube body 10 and providing higher safety.
