AI Technical Summary
The fixing method of existing carbon dioxide absorption bottles on anesthesia ventilators depends solely on surface friction, which leads to easy shedding when the device moves, increasing the risk of secondary infection.
A carbon dioxide absorbing bottle cap body is designed, including a tubular body, a first threaded connection and a second threaded connection, and is closely connected to the ventilator line of the carbon dioxide absorbing bottle and the anesthetic ventilator through a threaded connection.
The connection strength of the CO2 absorber bottle and the anesthesia ventilator is significantly enhanced through threaded connections, reducing the risk of falling off when the device moves, and reducing the possibility of secondary infection.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment industry, in particular to a carbon dioxide absorption bottle cap, a carbon dioxide absorption bottle device and an anesthesia breathing machine. Background Art
[0002] At present, the anesthesia ventilator adopts a closed circulation mode during mechanical ventilation. The exhaled gas (containing carbon dioxide mixed gas, mainly oxygen, or containing anesthetic gas) in the breathing circuit of the anesthesia ventilator is absorbed by the carbon dioxide absorption bottle 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 bottle 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 bottles on the anesthesia ventilators 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 bottle has emerged. However, the existing small-bottle disposable carbon dioxide absorption bottle 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 bottle 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 bottle cap body that can strengthen the connection strength between the carbon dioxide absorption bottle and the breathing tube of the anesthesia breathing machine. Utility Model Content
[0005] In view of the above problems in the prior art, the present application proposes a carbon dioxide absorption bottle cap, a carbon dioxide absorption bottle device and an anesthesia respirator, which can enhance the connection strength between the carbon dioxide absorption bottle and the breathing circuit of the anesthesia respirator.
[0006] One aspect of the utility model provides a carbon dioxide absorption bottle cap, which includes a tubular body, one end of the tubular body is provided with a first threaded connector, the first threaded connector can be connected to the bottle mouth of the carbon dioxide absorption bottle in a threaded and sealed manner, and the other end of the tubular body is provided with a second threaded connector, the second threaded connector can be connected to one of the connecting branch pipes of the three-way connector of the breathing circuit of the anesthesia ventilator in a threaded and sealed manner.
[0007] As a further improvement of the above technical solution:
[0008] The above-mentioned carbon dioxide absorption bottle cap body, further, the second threaded connector includes an internal thread arranged on the inner side wall of the other end of the tubular body, and the internal thread can be thread-sealed and connected with the external thread on the outer side wall of the connecting branch pipe.
[0009] The above-mentioned carbon dioxide absorption bottle cap body, further, the first threaded connector comprises a threaded cap, and the threaded cap can be connected with the bottle mouth thread of the carbon dioxide absorption bottle in a sealing manner.
[0010] The above-mentioned carbon dioxide absorption bottle cap body further has an outer side wall of the threaded cap provided with an anti-slip protrusion.
[0011] Another aspect of the utility model provides a carbon dioxide absorption bottle device, which includes a carbon dioxide absorption bottle and the carbon dioxide absorption bottle cover as described above, wherein the first threaded connector is connected to the bottle mouth thread of the carbon dioxide absorption bottle in a sealing manner.
[0012] Another aspect of the utility model provides an anesthesia breathing machine, which includes the carbon dioxide absorption bottle device as described above.
[0013] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the utility model can be achieved.
[0014] The carbon dioxide absorption bottle cap, carbon dioxide absorption bottle device and anesthesia respirator provided by the utility model have at least the following beneficial effects compared with the prior art: when the carbon dioxide absorption bottle needs to be replaced, the first threaded connector of the carbon dioxide absorption bottle cap is first connected with the thread seal of the bottle mouth of the carbon dioxide absorption bottle, and then the second threaded connector is connected with one of the connecting branch pipes of the three-way connector of the breathing tube of the anesthesia respirator to complete the replacement of the carbon dioxide absorption bottle. The carbon dioxide absorption bottle cap has one end connected with the thread seal of the bottle mouth of the carbon dioxide absorption bottle, and the other end connected with one of the connecting branch pipes of the three-way connector of the breathing tube of the anesthesia respirator. Compared with the existing connection method that is only fixed by surface friction, the connection strength between the carbon dioxide absorption bottle and the breathing tube of the anesthesia respirator can be strengthened, and when the anesthesia respirator moves, the risk of the carbon dioxide absorption bottle and the breathing tube of the anesthesia respirator falling off is reduced.
