Description

A portable visual tracheal intubation introducer

technical field

The invention relates to a medical auxiliary device, in particular to a portable visual tracheal intubation guider.

Background technique

Endotracheal intubation is part of the care of critically ill patients with multisystem disease or impairment, including cardiac beating, respiratory arrest, hypoxia, hypoventilation, airway obstruction, or failure to prevent aspiration. Endotracheal intubation is a must-have first aid measure in emergencies or emergencies. Endotracheal intubation is a very practical operation skill. Oral intubation under direct laryngoscope is simple, fast, less traumatic, easy to expel sputum, and has fewer complications. It is the most reliable and effective first aid measure in rescue. Due to some congenital and pathological reasons, some patients have abnormal upper airway anatomy, which makes it difficult to expose the glottis during tracheal intubation. Conventional tracheal intubation uses a tube core made of bendable, elastic, and tough soft thin copper strips. During difficult tracheal intubation, the front end of the tube is easily deformed and slips when the epiglottis is lifted up, making it difficult to enter the glottis. In order to improve the success rate of difficult tracheal intubation, some doctors choose a harder metal wire as the tube core. After using a harder tube core, some cases can expose part of the glottis when lifting the epiglottis, reducing the difficulty of intubation. , For difficult intubation cases with visible epiglottis, endotracheal intubation can be completed quickly. The hard tube core makes it difficult to change the radian of the outer mouth shape, and the front end of the catheter can move and advance arbitrarily in the desired direction in the throat, thereby improving the first-time success rate of intubation and shortening the intubation time. However, improper use of direct laryngoscope can lead to damage to the mouth, tongue, pharynx, and larynx, and damage, loosening or loss of teeth; due to the hard tube core, it is easy to damage the throat and airway mucosa, and even perforate the esophagus due to violence. Tracheal intubation is too deep, inserted into one side of the bronchus, easy to enter the right bronchus, resulting in atelectasis of the left lung. Fiberoptic bronchoscope-guided endotracheal intubation has a very high one-time success rate, less damage, and can drain large airway secretions to unblock the airway and save lower respiratory tract secretion specimens for inspection. The position requirements for intubation are not high, and it is suitable for spinal trauma It is especially beneficial for patients who are not suitable for changing positions such as heart failure or heart failure.

However, there are several problems with endotracheal intubation guided by fiberoptic bronchoscope:

(1) Fiberoptic bronchoscopy is relatively expensive.

(2) The preparation work before use is cumbersome.

(3) For those with difficulty in glottis exposure, it is difficult to intubate the trachea under the guidance of fiberoptic bronchoscope.

Fig. 3 is a sectional view of the introducer main body of another specific embodiment;

Fig. 4 is a reference diagram of the use state of the endotracheal tube shown in Fig. 1 .

Detailed ways

Fig. 1 and Fig. 2 have shown the structure diagram of the endotracheal intubation introducer of the present utility model, comprise introducer main body 1, handle 2, camera, light source and display screen 6; Introducer main body 1 is arc rod shape , and the shaft is provided with suction channel 3, camera installation channel 4 and light source installation channel 5; , the handle 2 is provided with a control box 7 for controlling the camera, light source and display screen 6, and the control box 7 is provided with a commonly used camera image processing circuit board and a power supply battery, and the battery supplies power to the camera, LED bulb and display screen. The curved arc of the introducer main body 1 is consistent with the curved arc of the throat of the human body, the bending radius is about 140±20mm, the outer diameter of the shaft is the same as the inner diameter of the endotracheal tube, about 5 to 6mm, and it is made of medical stainless steel , Therefore, it has a certain hardness and toughness, and can be easily inserted into the patient's throat.

Wherein, the front end of the suction channel 3 is open, and the end is connected with the external negative pressure suction device through the opening 8 on the handle. The front ends of the camera installation channel 4 and the light source installation channel 5 are closed by a transparent cover, and the camera and the light source are placed inside the closed end. Therefore, the light emitted by the light source can be transmitted through the transparent cover, and the camera can also collect images through the transparent cover. As shown in FIG. 2 , the camera installation channel 4 is provided with a camera connection line 40 for connecting the camera to collect image signals for display on the display screen, and the light source installation channel 5 is provided with an LED light bulb connection line 40 .

The main body of the introducer can also adopt the structure of another specific embodiment as shown in Figure 3, that is, the main body of the introducer 1 is in the shape of an arc cylinder, the outer diameter is about 5 to 6 mm, the inner diameter is about 4 to 5 mm, and the inner diameter is about 4 to 5 mm. There are three pipelines, which are respectively used as the suction channel 3, the camera installation channel 4 and the light source installation channel 5, and the front ends of the camera installation channel 4 and the light source installation channel 5 are closed with a transparent cover. Therefore, the guide body of the structure and the three Channels can be disassembled and assembled at any time.

As shown in the use state reference diagram in Figure 4, the use process of the endotracheal intubation introducer is: firstly, the endotracheal intubation tube 9 is set outside the introducer main body 1, and the introducer main body 1 is inserted into the patient's throat by holding the handle During the insertion process, rely on the light source and the camera to collect the head of the throat, and help to lift the epiglottis and insert it into the trachea by observing the output of the throat image on the display screen. suck out the sputum and interstitial fluid; when it reaches the proper position, push the tracheal intubation tube 9 forward along the introducer body 1 into the trachea; finally keep the endotracheal intubation tube 9 still Withdrawing, the endotracheal intubation operation is completed.

The handle of the portable visual tracheal intubation introducer of the utility model is provided with a foldable liquid crystal display screen, or adopts an external liquid crystal display screen, and can monitor the progress of the intubation in real time through the camera installed in the front end of the main body of the introducer. During the whole process, the introducer has the function of guiding the tracheal intubation. Because of its certain toughness, it can also be bent appropriately according to the conditions of different patients. In addition, the introducer is manipulated by handle control to elevate the epiglottis, exposing the larynx and glottis. The glottis and epiglottis can be seen very intuitively, the difficulty of intubation is reduced, the speed of intubation is accelerated, the accuracy of intubation is improved, and the intubation injury of patients is reduced at the same time. It is especially suitable for difficult intubation such as small mouth opening, stiff cervical spine, hypertrophic epiglottis, and high glottis. The length of the introducer can be made to be 350-370mm. Through the liquid crystal display, far away from the patient's head, the patient's glottis and epiglottis can be seen directly from the liquid crystal display, and the intubation and glottis can be completed. The inspection and observation can relatively keep the distance between the patient and the operator, provide a good operating environment for medical staff, reduce the chance of infection for medical staff, and make it safer for medical staff. At the same time, the introducer can also be extended and used in other examinations and surgical operations, such as oral glottic examination, tube replacement examination, gastric tube insertion, etc.
