Description
Technical Field
The invention belongs to the technical field of anesthesia equipment, and particularly relates to an anti-overflow intelligent volatile tank doser.
Background
The existing drug adding modes of the anesthetic volatilization pot are generally divided into two types: 1) directly adding the drugs or adding the drugs through a valve-filling funnel, opening a drug adding cover of the anesthetic volatilization pot, directly pouring the anesthetic into a drug adding port of the volatilization pot by holding an anesthetic bottle by an anesthesiologist, and screwing down the drug adding cover after the drug adding is finished; 2) the medicine adding mode needing the intermediate connection device is that a QuikFil system and a wedge filling system (keyedfilling) are commonly used at present, such as those used on an anesthesia machine of the American general electric company, an anesthesiologist opens an anesthetic medicine bottle and connects the intermediate connection device, then a medicine adding cover of an anesthetic volatilization tank is opened, or a wedge block of the medicine adding device is drawn out, the intermediate connection device is installed on the medicine adding device, the anesthetic medicine bottle adds medicine to the anesthetic volatilization tank through the intermediate connection device, and the medicine adding cover is covered or the wedge block is inserted into the medicine adding device after the medicine adding is finished.
The drug adding mode of the direct drug adding is very convenient, the drug cannot be added due to the damage and the loss of the intermediate device, but the drug adding mode is directly added in the drug adding process of an anesthesiologist, a small amount of volatile anesthetic enters the surrounding environment, after the drug adding is finished, if the anesthetic is not screwed down by the drug adding cover, the leakage of the anesthetic can occur, the surrounding operation environment is polluted, the anesthetic is wasted, and the health of medical care personnel is influenced.
As for the dosing mode with the intermediate device, in the dosing process, although volatilization of anesthetic can be reduced as much as possible, the hidden troubles of damage and loss of the intermediate device exist, once the intermediate device is lost or damaged, dosing cannot be carried out, and the dosing quantity cannot be controlled.
In summary, the existing volatile pot doser has the following defects:
1) the existing medicine adding device is single in functionality and only used for sealing an anesthetic adding port, and whether the anesthetic is added fully or not cannot be known in the medicine adding process, so that the anesthetic overflows from the medicine adding port; (ii) a
2) When the medicine is directly added, if the medicine adding cover is not screwed down after the medicine is added, the anesthetic is leaked, and danger is caused;
3) for wedge and QuikFil dosing modes, an intermediate device is required, if the intermediate device is lost or damaged, dosing cannot be carried out, and the volatilization tank cannot be used.
Disclosure of Invention
The invention aims to provide an anti-overflow intelligent volatile pot doser which can realize sealing and control the dosing amount.
Anti-overflow intelligence jar doser that volatilizees in this scheme, including be located jar that volatilizees and add medicine mouth on and be used for periodic storage and release anesthetic with add medicine lid and the conveyer pipe that jar that volatilizees and connect respectively with set up pillar in the medicine lid, it is equipped with a plurality of isovolumic and with to add in the medicine lid the pillar is the anesthetic cavity that central circumference arranged the setting, every all be equipped with import and export on the anesthetic cavity, be equipped with the confession in the import the first valve that anesthetic flowed in, just be located in the anesthetic cavity import department be equipped with be used for to spray the nozzle of anesthetic in the anesthetic cavity, the export is equipped with the confession the second valve that the anesthetic flowed out, the second valve is connected the conveyer pipe.
The working principle of the invention is as follows:
when the product of the invention is used, when the anesthetic enters the dosing cover, the first valve on the anesthetic cavity is manually opened, the anesthetic is sprayed into the anesthetic cavity through the nozzle, during the spraying process, the anesthetic is volatilized rapidly, then the first valves on the adjacent anesthetic chambers are started manually to be opened, the principle of rapidly volatilizing the anesthetic is the same as the above, all the first valves on the anesthetic chambers are opened in sequence, when the anesthetic chambers are fully stored with the anesthetic, after a period has expired, the second valve of the first anesthetic-containing chamber is manually actuated, the anesthetic in the anesthetic cavity is conveyed into the conveying pipe, and then the second valve of the adjacent anesthetic cavity is started, according to the flow, the second valve of each anesthetic cavity is opened in sequence, so that the volatilized anesthetic in each anesthetic cavity is conveyed into the volatilization tank.
The invention has the beneficial effects that:
(1) compared with the prior art, the anesthetic chamber disclosed by the invention adopts a plurality of anesthetic chambers which are used for storing anesthetic and adjusting the concentration of anesthetic, and because the volume of each anesthetic chamber is equal, the amount of the anesthetic sprayed by the nozzle is equal when the anesthetic is sprayed into the anesthetic chambers.
