Description

A kind of anaesthetic backflows monitoring device

Technical field

It backflows monitoring device the utility model relates to field of medical device more particularly to a kind of anaesthetic.

Background technique

Necessary link of the vein continued administration as operating room patient with operation general anesthesia is theatre sister and anesthesia doctor Raw groundwork.After patient with operation completes anesthesia induction, Intravenous Infusion anaesthetic need to be established to maintain patient with operation Narcosis to ensure the smooth implementation of operation.But in clinical position, usually because of change (the root after anesthesia of patient body position Need to carry out position adjustment according to operation) cause the distortion of venous detaining needle or folding to cause venoclysis obstructed and anaesthetize Drug backflows, i.e., anaesthetic injects patient's body without tee tube, but backflows through tee tube to infusion tube, leads to hand Art patient does not have the anaesthetic of continuous and effective to be transfused and influence the smooth implementation of operation, or even intraoperative diagnosis occurs (in operation Consciousness recovery occurs), the life security of patient is seriously threatened, is brought greatly to Anesthetist, patient with operation and family numbers of patients Trouble.Therefore, it studies and develops a kind of anaesthetic and backflow monitoring device, it is existing to have found that it is likely that the anaesthetic of appearance backflows in time As and remind rounding nurse in operating room and Anesthetist, to avoid there is related adverse consequences, be of great significance.

If the patent document of Publication No. CN205007376U provides a kind of " transfusion monitoring device ", for by being infused The liquid that pipe enters in Perfusion drip funnel is monitored, and drips fast detection unit including being set to drop at Perfusion drip funnel, and described Drop drips the joining controller of fast detection unit, and is set at the perfusion tube of Perfusion drip funnel upstream, reception controller Control signal to adjust the infusion regulating mechanism of the flow area size of perfusion tube；It further include joining with the controller Display module, and receive controller control signal and the alarm module that acts.Generally can be realized to infusion situation into Row monitoring, coutroi velocity grasp transfusion state, reasonable arrangement time, but poor anti jamming capability convenient for medical staff, and are single Machine uses, and the reaction chain of system perfecting, does not allow medical staff that can understand patient's condition in real time, handles, does not have in time Anesthesia monitoring.

For another example the patent document of Publication No. CN106730162A provides " a kind of intelligent transfusion warning device and system ", Device includes shell, warning circuit and the remote controler being wirelessly connected with warning circuit, wherein warning circuit includes: controller, drop Fast detector, liquid level wireless detector, timer, wireless communication module, liquid crystal touch screen and combined aural and visual alarm drip fast detector For detecting the drop speed of medical fluid in Mo Feishi dropper；Liquid level wireless detector is used to detect the liquid of infusion bottle or infusion bag Chinese medicine liquid Face height；Liquid crystal touch screen is used to receive the infusion parameter of user's input；Controller is used to be believed according to the fast information of drop, liquid level Breath and infusion parameter, calculate remaining liquid volume in present infusion bottle or infusion bag, and remaining liquid volume lower than threshold value or When liquid level is lower than default safety level height, driving combined aural and visual alarm alarm, while alarm signal is sent to remote controler.It is logical Above-mentioned technical proposal is crossed, can be realized the intelligent monitoring of infusion rate and progress of being infused, the device detection device is more, detects more Used type of alarm is relatively single when kind situation, meanwhile, medical staff can not be notified at the first time, and cannot be shown The reason of showing actual alarm, medical staff can not prepare in advance according to making the case where actually appearance.
