Description

Spill-proof smart vaporizer doser

technical field

The invention belongs to the technical field of anesthesia equipment, in particular to an anti-overflow intelligent volatilization tank dosing device.

Background technique

The existing dosing methods of anesthesia volatilizers are generally divided into two categories: 1) direct dosing or dosing through an injection valve funnel. Pour the anesthetic agent into the dosing port of the volatilizer, and tighten the dosing cap after the dosing is completed; 2) The dosing method that requires an intermediate connection device is commonly used now such as the QuikFil system used on the anesthesia machine of General Electric Company of the United States And wedge-shaped perfusion system (keyedfilling), the anesthetist opens the anesthetic bottle and connects the intermediate connection device, then opens the dosing cap of the anesthesia vaporizer, or pulls out the wedge of the doser, and installs the intermediate connection device to the doser Above, the anesthesia drug bottle is added to the anesthesia volatilization tank through the intermediate connection device, and after the drug addition is completed, the drug addition cap is closed or the wedge is inserted into the drug doser.

The above-mentioned direct dosing method is very convenient, and it will not fail to dosing due to damage or loss of the intermediate device, but the direct dosing method will cause a small amount of anesthetic to volatilize and enter the surrounding area during the dosing process of the anesthetist. Environment, after the dosing, if the anesthesiologist does not tighten the dosing cap, the anesthesia will leak, pollute the surrounding surgical environment, cause a waste of anesthesia and affect the health of medical staff.

For the dosing method with an intermediate device, although the volatilization of the anesthetic can be reduced as much as possible during the dosing process, there are hidden dangers of damage and loss of the intermediate device. Once the intermediate device is lost or damaged, the dosing will not be possible, and the amount of dosing Can't control it yet.

In summary, the existing volatilizer dosing device has the following defects:

1) The current dosing device has a single function, which is only used to close the anesthetic dosing port, and in the process of dosing, it is impossible to know whether the anesthetic is filled, so that the anesthetic overflows from the dosing port;

2) In the direct dosing mode, if the dosing cap is not tightened after dosing, the anesthetic will leak and cause danger;

3) For the wedge-shaped and QuikFil dosing methods, it is necessary to rely on the intermediate device. If the intermediate device is lost or damaged, the dosing cannot be done, which may make the volatilizer unusable.
