Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical devices, and particularly relates to a tracheal intubation visualization component which is convenient for disassembly. Background Art
[0002] Tracheal intubation is a common method for establishing an artificial airway in emergency situations, aiming to maintain ventilation function, clear secretions, and perform mechanical ventilation. The specific operation of tracheal intubation is to insert a special catheter into the trachea through the oral cavity or nasal cavity, directly connecting the lungs with the outside world to ensure oxygen delivery and carbon dioxide excretion; its core purpose is to solve problems such as airway obstruction, respiratory failure, or respiratory management under general anesthesia. For example, in cases of cardiac arrest, severe trauma, or severe pneumonia resulting in the loss of spontaneous breathing, tracheal intubation can quickly establish effective ventilation and gain time for subsequent treatment.
[0003] Since the tracheal intubation itself cannot provide the corresponding insertion vision, in order to prevent the tracheal intubation from being accidentally inserted into the esophagus during the intubation process, medical staff need to rely on the vision provided by the laryngoscope and the markers in the vision to distinguish the esophagus and the respiratory tract, so as to complete the accurate insertion of the tracheal intubation. Although the laryngoscope and the video laryngoscope can provide the corresponding operative field for the insertion of the tracheal intubation, the insertion and posture fixation of the laryngoscope often require the assistance of others to successfully complete the insertion of the tracheal intubation. This assistance method not only occupies more medical staff but also prolongs the insertion time of the tracheal intubation.
[0004] Currently, some visual tracheal intubations have also emerged on the market. However, they integrate a visual micro camera at the front end of the tracheal intubation, and then lead out the camera image transmission connector from the rear end of the tracheal intubation. Although this method can solve the problem that the tracheal intubation cannot provide an operative field, this visual tracheal intubation still has the following problems: 1. Since the tracheal intubation is a disposable medical consumable, the tracheal intubation with an integrated camera will significantly increase the medical cost, resulting in difficulties in its popularization; 2. Adding an integrated camera at the front end of the trachea often requires sacrificing the ventilation area of the tracheal intubation to arrange the corresponding transmission wires, resulting in a reduction in the effective ventilation area of the tracheal intubation, affecting the subsequent mechanical ventilation effect, and the discard after use will cause serious waste of resources; 3. There are problems of sputum or bleeding in the respiratory tract of some patients. The presence of sputum and blood will affect the operative field of the camera. How to clear sputum and blood while inserting the tracheal intubation to solve the problem of operative field occlusion is a technical problem that needs to be solved; 4. The tracheal intubation needs to be fixed on the respiratory tract by the inflation of the cuff. The cuff will exert pressure on the respiratory tract. If the pressure is too small, it cannot be effectively fixed. If the pressure is too large, problems such as damage and necrosis of the respiratory tract mucosa will occur. How to quickly inflate the gas to the target air pressure to expand the cuff is also a current technical problem. Summary of the Utility Model
[0005] In order to solve the above technical problems, the utility model provides a tracheal intubation visualization assembly which is convenient to disassemble. This assembly can be quickly installed into or disassembled from a tracheal intubation. It can provide surgical field support for the insertion of the tracheal intubation, and there is no need to sacrifice the ventilation area of the tracheal intubation. After disassembly, it does not affect the ventilation effect of the tracheal intubation. This assembly can also aspirate sputum and blood in the respiratory tract by negative pressure during the insertion of the tracheal intubation, prevent sputum and blood from blocking the surgical field, and ensure the smooth insertion of the tracheal intubation. At the same time, this assembly can also timely give the cuff a target air pressure after successful tracheal intubation, so that the cuff can be fixed on the inner wall of the respiratory tract with a reasonable air pressure. This assembly can be used in conjunction with most tracheal intubation products on the current market. As a reusable component, its application cost is lower than that of disposable visualization tracheal intubation products and it is convenient to promote.

After the hollow tube body is completely inserted into the main ventilation tube, the third cuff passes over the air exchange hole and is located in front of the air exchange hole.
[0028] In this embodiment, the single-chip microcomputer is a 51 series single-chip microcomputer. The power supply module is an AMS1117-3.3V power conversion module. The analog-to-digital conversion module is an ADC0864 type analog-to-digital conversion chip. The digital-to-analog conversion module is a DAC0832 type digital-to-analog conversion chip. The image processing module is a DM642 image processing chip.
[0029] A specific application of this device is as follows: Insert the visual double-lumen catheter 14 along the main airway tube of the endotracheal tube 1 until the disassembly sleeve 91 is inserted onto the main airway joint 7. Turn on the image acquisition switch button of the micro camera. At this time, the control circuit board will turn on and drive the micro camera to take pictures. Insert the endotracheal tube 1 together with the visual double-lumen catheter 14 into the patient's oral cavity. During the insertion process, the LED beads of the camera module 151 with LED beads emit illumination light, and the camera performs image acquisition and transmits the images to the image processing module of the control circuit board through the image transmission wire 142. The image processing module then performs image conversion and transmits it to the single-chip microcomputer, which is then transmitted by the single-chip microcomputer to the display screen for display. At this time, the landmark points of the respiratory tract can be directly found according to the displayed images, so that the main airway tube of the endotracheal tube 1 enters the respiratory tract; during the insertion of the endotracheal tube, if sputum or blood appears in the respiratory tract, in order to prevent it from blocking the surgical field of view, the negative pressure drainage switch button can be turned on. At this time, the control circuit board connects the power supply circuit of the negative pressure pump through the first micro relay. At this time, the negative pressure pump sucks the air in the negative pressure collection bottle and discharges it to the outside environment. The negative pressure collection bottle 17 is in a negative pressure state, and the negative pressure is transmitted through the drainage tube and the negative pressure drainage channel. The sputum and blood enter the negative pressure collection bottle through the negative pressure drainage channel and the drainage tube. The front end of the suction tube 27 on the negative pressure pump is fixed with a waterproof and breathable membrane 28, which can prevent sputum and blood from entering the negative pressure pump to continuously suck the negative pressure collection bottle and maintain the negative pressure state; after the sputum and blood are cleared, continue to insert the endotracheal tube to the target position. Then connect one end of the catheter 10 to the cuff constant pressure inflation joint 11 and the other end to the first inflation joint 5 or the second inflation joint 6. Set the inflation pressure value of the cuff through the cuff inflation adjustment button. Then the control circuit board connects the power supply circuit of the inflation pump 22 through the second micro relay, and the inflation pump inflates. During the inflation process, the pressure sensor will continuously detect the air pressure in the inflation pipeline. Since the first cuff or the second cuff is connected to the inflation pipeline through the catheter, the air pressure value detected by the pressure sensor is the air pressure of the first cuff or the second cuff. When the air pressure value reaches the set value, the control circuit board disconnects the power supply circuit of the inflation pump through the second micro relay to prevent over-inflation. Plug the plugs into the first inflation joint and the second inflation joint to complete inflation and fixation; finally, remove this component, insert the sheath tube into the endotracheal tube, and complete the lung lobe surgery under airway occlusion.
