Description

Measurable multifunctional safe closed type sputum suction device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a measurable multifunctional safe closed sputum suction device.

Background

Clinically, patients who are ventilated mechanically and patients who establish artificial airways need sputum aspiration care. When the medical personnel is inhaling the phlegm operation, on the one hand will reach the purpose of clearance sputum, and on the other hand still will measure, reserve and get the sputum sample to the sputum of suction, will ensure patient's safety simultaneously, prevent infection etc. in the hospital. The existing closed sputum suction tube commonly used in clinic can solve the problems that the treatment of a breathing machine is interrupted when sputum is sucked, and an air passage is exposed to air, and prevent cross infection, but still has more defects. Firstly, a device for preventing aspiration is lacked, when medical staff uses the existing closed sputum suction tube to perform sputum suction operation, on one hand, the flushing fluid is communicated with the airway when the sputum suction tube is flushed, and if the negative pressure aspiration cannot timely and quickly suck all the flushing fluid away, the flushing fluid may enter the airway of a patient; on the other hand, after the sputum suction tube is flushed, once medical personnel forget to close the valve of the flushing fluid, the flushing fluid can directly flow into the air flushing pipe joint of the patient, the patient can be choked and coughed and sucked by mistake under the two conditions, and the patient can be suffocated by serious patients. Secondly, lack the device of measurement sputum, most sputum is estimated by medical personnel, can't guarantee the accuracy of measurement. Third medical personnel can't inhale phlegm device through current closed and carry out the collection of sputum sample, during the collection sample, medical personnel often need breathe through the separation and wash the coupling, carry out the open phlegm of inhaling and stay the phlegm sample, can influence patient's breathing machine treatment like this, also can increase the risk that patient infects and medical personnel occupation expose, in addition because the closed inhales phlegm pipe lumen and patient's artifical air flue and breathing machine and washes the coupling and communicate with each other, partial gas can get into the closed when mechanical ventilation and inhales in the phlegm pipe device, influence the effect of breathing machine treatment.

Disclosure of Invention

The invention aims to solve the technical problems that when a sputum suction pipe is flushed, flushing fluid enters a patient airway, medical staff forget to close a valve of the flushing fluid due to negligence so as to cause potential risks to the patient, and treatment of a respirator is influenced due to a closed sputum suction device in the prior art, and provides a measurable multifunctional safe closed sputum suction device which can accurately measure sputum and conveniently retain a sputum sample for the medical staff, can effectively prevent the flushing fluid from entering the patient airway, and avoids the situation that the patient is choked and choked due to aspiration.
