Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment industry, in particular to a carbon dioxide absorption tank cover, a carbon dioxide absorption tank device and an anesthesia breathing machine. Background Art
[0002] At present, anesthesia ventilators use a closed circulation mode for mechanical ventilation. The exhaled gas (containing carbon dioxide mixed gas, mainly oxygen, or anesthetic gas) in the breathing circuit of the anesthesia ventilator is absorbed by the carbon dioxide absorption tank and then re-enters the breathing circuit for use, ensuring that the patient will not repeatedly inhale this gas, thereby protecting the patient's life safety. The working principle of the carbon dioxide absorption tank is that the carbon dioxide absorbent loaded therein reacts chemically with carbon dioxide, thereby achieving the absorption of carbon dioxide.
[0003] The carbon dioxide absorbent bottles currently in use are mainly packaged in large barrels, which are filled into the carbon dioxide absorbent tank on the anesthesia ventilator by medical staff. This has two problems: first, it is very inconvenient for medical staff to operate; second, after being used by multiple surgical patients, the risk of secondary infection of the anesthesia equipment and surgical patients is very high.
[0004] Therefore, a small-bottle disposable carbon dioxide absorption tank has emerged. However, the existing small-bottle disposable carbon dioxide absorption tank does not fully consider how to fix it on the breathing tube of the anesthesia breathing machine, and is only fixed by surface friction. When the anesthesia breathing machine moves, the carbon dioxide absorption tank and the breathing tube of the anesthesia breathing machine are very likely to fall off. Therefore, it is necessary to design a carbon dioxide absorption tank cover that can strengthen the connection strength between the carbon dioxide absorption tank and the breathing tube of the anesthesia breathing machine.

[0007] As a further improvement of the above technical solution:
[0008] The above-mentioned carbon dioxide absorption tank cover body, further, the clamping surface of the clamping block that can be clamped with the clamping ring is parallel to the radial direction of the tubular body, and the top of the clamping block to the end of the claw is a first inclined guide surface.
[0009] The above-mentioned carbon dioxide absorption tank cover body, further, the threaded connection piece includes a threaded cap, and the threaded cap can be connected with the tank mouth thread of the carbon dioxide absorption tank in a sealing manner.

[0030] The embodiment of the utility model provides a carbon dioxide absorption tank cover 100, which can enhance the connection strength between the carbon dioxide absorption tank and the breathing circuit of an anesthesia breathing machine.
[0031] See also Figure 1 and Figure 2The carbon dioxide absorption tank cover body 100 provided by the embodiment of the utility model includes a tubular body 110, one end of the tubular body 110 is provided with a threaded connector 120, the threaded connector 120 can be sealed and connected with the tank mouth of the carbon dioxide absorption tank, and the other end of the tubular body 110 is provided with a plurality of claws 130 at intervals along the circumferential direction, and the claws 130 are provided with a clamping block 131, which can be clamped on the clamping ring 211 of the outer wall of one of the connecting branches 210 of the three-way connector 200 of the breathing circuit of the anesthesia ventilator.
[0032] When the carbon dioxide absorption tank needs to be replaced, first, the threaded connector 120 of the carbon dioxide absorption tank cover 100 is sealed and connected with the tank mouth thread of the carbon dioxide absorption tank, and then a plurality of claws 130 are sleeved on the outside of one of the connecting branches 210 of the three-way connector 200 of the breathing circuit of the anesthesia ventilator, and the carbon dioxide absorption tank cover 100 is moved along the axial direction of the connecting branch 210 until the clamping block 131 is clamped on the clamping ring 211 on the outer wall of the connecting branch 210, thereby completing the replacement of the carbon dioxide absorption tank.
[0033] The carbon dioxide absorption tank cover body 100 provided in the embodiment of the utility model has one end of the carbon dioxide absorption tank cover body 100 sealedly connected with the tank mouth thread of the carbon dioxide absorption tank, and the other end of the carbon dioxide absorption tank cover body 100 is clamped to the clamping ring 211 on the outer wall of the connecting branch pipe 210 through the clamping block 131. Compared with the existing connection method that only relies on surface friction to fix, the connection strength between the carbon dioxide absorption tank and the breathing tube of the anesthesia respirator can be strengthened, and when the anesthesia respirator moves, the risk of the carbon dioxide absorption tank and the breathing tube of the anesthesia respirator falling off is reduced.
[0034] The carbon dioxide absorption tank cover 100 provided in the embodiment of the present invention is further described in detail. Figure 1 and Figure 2 The engaging surface 132 of the clamping block 131 that can be engaged with the clamping ring 211 is parallel to the radial direction of the tubular body 110, and the first inclined guide surface 133 is formed from the top of the clamping block 131 to the end of the claw 130. The abutting surface 212 of the clamping ring 211 that can be engaged with the clamping block 131 is parallel to the radial direction of the connecting branch pipe 210, and the side of the clamping ring 211 close to the carbon dioxide absorption tank cover 100 is the second inclined guide surface 213.
[0035] When the carbon dioxide absorption tank cover body 100 needs to be installed on one of the connecting branches 210 of the three-way connector 200 of the breathing circuit of the anesthesia ventilator, firstly, a plurality of claws 130 are sleeved on the outer side of one of the connecting branches 210 of the three-way connector 200 of the breathing circuit of the anesthesia ventilator, and the carbon dioxide absorption tank cover body 100 is moved along the axial direction of the connecting branch 210, and the first inclined guide surface 133 of the block 131 and the second inclined guide surface 213 of the clamping ring 211 are guided and cooperated so that the claws 130 are gradually bent and deformed radially outward along the tubular body 110 until the block 131 crosses the clamping ring 211, and the claws 130 are restored to deform radially inward along the tubular body 110 so that the clamping surface 132 of the block 131 abuts against the abutting surface 212 of the clamping ring 211.
