Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a novel intubation hard mirror with a sputum suction function.
Background
The endotracheal intubation technique is a medical operation in which a tracheal catheter is placed into the trachea through the glottis through the oral cavity, and is widely applied to the fields of emergency treatment, general anesthesia, ICU (acute coronary syndrome) ventilator treatment and the like. Under the environment of epidemic situation of new coronary pneumonia, the endotracheal intubation technology plays a role in the treatment process of severe patients with new coronary pneumonia. The traditional laryngoscope is used for intubation operation, so that the defects of large operation stimulation, more side damage, inaccurate intubation, large learning difficulty, low intubation success rate of patients with difficult airways and the like exist. Therefore, the tube core intubation technology is becoming more widely used clinically. Hard scope intubation is becoming increasingly popular with clinicians as a technique for core intubation.
Many patients in clinic are because long-term smoking, inflammation are amazing, lead to the respiratory tract to secrete the sputum more, and the sputum adheres to very easily and blocks the operator field of vision in hard mirror head end, and the existence of sputum seriously influences the operator and judges local structure, has prolonged the intubate time, greatly reduced hard mirror intubate's success rate. In addition, if sputum in the oral cavity is brought into the trachea in the intubation process, lung infection is easily caused, and the recovery of the lung function of a patient after operation is influenced. Therefore, timely sputum aspiration during the hard scope intubation process becomes especially important. At present, the common sputum suction pipe is mainly adopted clinically, sputum suction operation is carried out outside the tracheal catheter, and the sputum suction mode has the main defects that: 1. the ordinary sputum suction tube needs to be operated by two hands to control the in-and-out direction of the sputum suction tube, and an assistant is needed to assist in sputum suction operation in the intubation process; 2. the sputum suction tube is directly inserted into the oral cavity and goes in and out of the tracheal catheter, the controllability of the direction of the sputum suction tube is poor, and the sputum suction position is not exact; 3. the sputum suction tube is difficult to suck the sputum which is adhered to the hard mirror.
In recent years, some patents propose solutions to the above problems, and propose a design scheme of a hard mirror (visible tube core) capable of sucking sputum, but some defects and inconveniences exist, and the sputum sucking and intubation effects are affected. At present, hard sputum suction scopes are roughly divided into the following two types:
the first type, sputum aspiration hard scope between the endotracheal tube and the hard scope, such as: a video light bar (authorized bulletin No. CN209048838U authorized bulletin day: 2019.07.02) with oxygen supply, airway administration and airway suction is provided, and the side connection opening 42 is connected with external negative pressure to suck out sputum at trachea through the space between a trachea cannula 5 and a bar body 1. The main disadvantages are: 1. sputum is inhaled through the inner wall of the tracheal catheter, a lot of sputum can be adhered to the inner wall of the tracheal catheter, the tracheal catheter is connected with a respirator after intubation is finished, and the sputum adhered to the inner wall of the tracheal catheter can be inhaled into the lung of a patient or cause pollution in the respirator; 2. the tip of the tracheal catheter is often provided with a side hole, and air can be sucked from the side hole by sucking phlegm through the space between the tracheal cannula 5 and the rod body 1, so that the phlegm sucking effect at the tip of the tracheal catheter is poor; 3. sputum can be adhered to the bar body 1 and the side connecting port 42, and needs to be disinfected and cleaned again after operation; 4. the lack of a suction control switch in the device prevents the operator from directly controlling the start and stop of suction.
The second category, suction of hard sputum via the interior of hard lens, is: when the visual multifunctional tracheal catheter tube core (authorized bulletin number: CN204092773U authorized bulletin date: 2015.01.14) is used for establishing an artificial airway, an operator turns on the video signal emission switch 6 and the switches of the display screen 7, simultaneously connects the negative pressure suction device to the suction connecting joint 8, and then inserts the tube core body 1 into the tracheal catheter. During intubation, the tube core body 1 is held to the right hand and patient's oral secretion is attracted while seeing display screen 7, insert the trachea catheter into the air flue slowly along patient's lingual surface simultaneously, the left hand is pushed down patient's lingual surface and is held up patient's lower jaw, attract head 2 to attract patient's oral secretion and get into the negative pressure aspirator through attracting connector 8 in, under the irradiation of light source head 4, the video file of 3 collections of making a video recording converts video signal into through video signal transmitter 5 and carries out wireless transmission, display screen 7 receives the wireless video signal of 5 launches of video signal transmitter and carries out the demonstration. The main disadvantages are: 1. the suction head 2, the camera 3 and the light source head 4 are designed to be parallel and level, when the suction head is close to sputum for suction, part of the sputum still adheres to the surfaces of the camera 3 and the light source head, and the visual field of an operator is influenced; 2. the sputum is deformed in the pipeline communicated with the suction head 2 through the suction connecting joint 8, so that the sputum is easy to remain and adhere to the pipeline, and the blockage of the channel is polluted if the sputum needs to be cleaned in time, and the sputum suction effect is influenced; 3. when the conventional hard endoscope is used for intubation, in order to avoid pollution and protect the hard endoscope, the front end of the tracheal catheter needs to exceed the front end of the hard endoscope, and the hard endoscope is completely wrapped in the tracheal catheter. At this time, sputum is sucked through the front end of the hard lens and cannot be fully touched; 4. the lack of a suction control switch in the device prevents the operator from directly controlling the suction to start or stop.
In view of the above, the present invention is particularly proposed.
