Trachea cannula

Technical Field

The utility model relates to the field of medical equipment, in particular to a trachea cannula.

Background

Hospital Acquired Infections (HAI), also known as nosocomial infections or nosocomial infections, are defined as all infections occurring in hospitals, with difficulty in diagnosis and treatment after infection and high mortality. Hospital-acquired pneumoconia (HAP) is taken as an example, HAP/VAP belongs to hospital-acquired infection, and the cross-sectional survey result of large-scale hospital infection in China shows that the incidence rate of hospital-acquired infection in the traditional Chinese medicine of inpatients is 3.22% -5.22%, wherein the hospital-acquired lower respiratory infection is 1.76% -1.94%. The incidence of hospital-acquired infections in hospitalized patients in the united states was 4.0%, with pneumonia accounting for 21.8% of hospital-acquired infections. The incidence of HAP is (5-10)/1000 hospitalized patients, accounting for up to 25.0% of the total number of infections in Intensive Care Units (ICU). The average hospitalization time is prolonged by 7-10 days after HAP occurs, and the hospitalization medical cost is greatly increased; HAP is also the direct cause of death in critically ill patients, with associated mortality rates as high as 15.5% -38.2%. HAI occurs for a number of reasons, and medical procedures are considered to be one of the important reasons.

The technology of placing a special endotracheal tube into the trachea through the glottis is called trachea intubation, and the technology can provide optimal conditions for smooth air passage, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like. The emergency trachea cannula technology becomes an important measure in the process of cardio-pulmonary resuscitation and emergency treatment of critically ill patients accompanied with respiratory dysfunction. The trachea intubation is an important rescue technique commonly used in emergency treatment work, is one of the most widely, effectively and quickly applied means in respiratory tract management, is a basic skill which must be mastered by medical staff in special departments such as anesthesia departments and the like, and plays a vital role in rescuing the life of a patient and reducing the fatality rate. As one of the most critical measures to rescue critically ill patients, the operational effectiveness of endotracheal intubation significantly affects patient prognosis. Studies have shown that endotracheal intubation patients develop an extremely high proportion of HAI, and the associated infection resulting from the intubation procedure may be one of their underlying causes.

During the intubation procedure, although the endotracheal tube itself is sterilized, infection from the patient himself cannot be avoided. In clinical practice, the trachea cannula directly enters the lower respiratory tract after reaching the glottis through the oral cavity and the throat, and pathogens of the upper respiratory tract easily enter the lower respiratory tract along with the trachea cannula in the operation process to cause the infection of the lower respiratory tract because the lower respiratory tract is in an aseptic environment.

Example 1:

referring to fig. 1-2, a tracheal cannula comprises a tracheal catheter 2, wherein an oblique-cutting insertion opening 8 is formed in the front end of the tracheal catheter 2, and an oxygen connector is arranged at the rear end of the tracheal catheter 2; the lateral surface of the insertion opening 8 is provided with a Murphy's eye 7, and the back of the insertion opening 8 is provided with a cuff 6; the tracheal catheter 2 is provided with an inflation tube 3 in a penetrating way, the upper part of the inflation tube 3 is positioned at the outer side of the tracheal catheter 2 and is communicated with an indicating saccule 4 with a one-way valve, and the lower part of the inflation tube 3 penetrates through the inner cavity of the tracheal catheter 2 and is communicated with a cuff 6; the lower part of the tracheal catheter 2 is sleeved with a transparent sterile film protective sleeve 5, one side of the sterile film protective sleeve 5 is provided with an easily-torn linear weak structure 11, and the linear weak structure 11 passes through the lower end of the sterile film protective sleeve 5 and extends to the other side; the outer surface of the tracheal catheter 2 is provided with scale marks for indicating the insertion depth of the tracheal catheter 2.

In this embodiment, it can be seen from fig. 3 that the endotracheal intubation procedure is required when a serious respiratory problem occurs or when a patient needs to be supported by breathing through mechanical ventilation during an emergency such as general anesthesia during an operation. The specific operation of the tracheal intubation is that firstly, a patient lies on the back, the head leans backwards, and the neck is lifted, so that the mouth, the throat and the trachea of the patient form a straight line; the thumb of the right hand pushes the lower lip and the lower jaw of the patient away, the index finger pushes against the incisors, the left hand holds the laryngoscope and enters the oral cavity along the right oral horn to press the tongue back, the tongue body is pushed to the left side, after the uvula (little tongue) is exposed, the lens of the laryngoscope is slowly pushed along the natural radian of the throat, and when the top end of the laryngoscope reaches the tongue root, the epiglottis and the glottis 12 can be seen; then, the doctor can enable the tracheal catheter 2 to reach the glottis 12 through the oral cavity and the throat, at the moment, the upper end of the linear weak structure 11 of the sterile film protective sleeve 5 is pulled, under the combined action of pulling force and the tracheal catheter 2, the sterile film protective sleeve 5 is pulled and pulled out along the linear weak structure 11, and in the pulling-out process, the tracheal catheter 2 can play a guiding role in pulling out the sterile film protective sleeve 5; after the sterile film protective sleeve 5 possibly carrying upper respiratory tract pathogens is separated, the uncontaminated tracheal catheter 2 is exposed, and the tracheal catheter 2 is continuously pushed to be inserted into a trachea through the glottis 12 opening; thereby avoiding bringing upper respiratory tract pathogens into the sterile environment of the lower respiratory tract trachea and avoiding causing hospital acquired infection caused by medical operation; once the tracheal catheter 2 is in place, a doctor can inflate the balloon by indicating the balloon 4 to enable gas to enter the cuff 6 through the inflation tube 3, the gas can open the cuff 6 to enable the cuff 6 to be tightly attached to the airway, and therefore the airway is closed and the tracheal cannula is fixed; then the laryngoscope is taken out, and the tracheal cannula is fixed at the corner of the mouth by adhesive tape to further prevent the tracheal cannula from moving and sliding out; and finally, butting oxygen supply equipment such as a breathing machine or a breathing air bag and the like with the oxygen interface 1, ventilating the tracheal catheter 2, and auscultating lung sounds to ensure that the intubation is in place, thereby completing the tracheal intubation operation.

During tracheal intubation, because the distance between different persons from the oral cavity to the valve is very small, a doctor can judge the insertion position of the tracheal catheter 2 through the scale marks arranged on the body of the tracheal catheter 2, so as to judge whether the insertion opening 8 is close to the glottis 12, and thus, the time for tearing off the sterile film protective sleeve 5 is determined. Except utilizing pipe shaft scale mark, still there are not few trachea cannula auxiliary assembly among the current medical equipment, its basic structure is the guiding tube of a front end area camera, stretch into trachea catheter 2 within let it stretch into the trachea with trachea catheter 2 together, pass back the image in real time through its front end camera, thereby can be more accurate judgement tear aseptic film protective sheath 5 the opportunity, can also ensure the exactness of trachea catheter 2 insertion position in the trachea.
