Description

an endotracheal tube

technical field

The utility model relates to a tracheal intubation tube, which belongs to the field of medical instruments.

Background technique

Endotracheal intubation is a general anesthesia operation in which a tracheal intubation is inserted into the human trachea through the mouth or nose to ensure good ventilation of the patient during the operation. Endotracheal intubation has been used clinically for a long time. Endotracheal intubation is a method to treat and improve the breathing of patients. It is an indispensable auxiliary medical device for failure and contributes to the rescue of patients with respiratory failure. The tracheal intubation should have sufficient rigidity and be resistant to folding or kinks.

The tracheal intubation used in the hospital is to inflate the air bag located at the lower part of the tube body through the balloon tube, and then use the expanded balloon tube to position the tube body in the patient's trachea. However, because the current tracheal tube has only one The infusion chamber, that is, the oxygen inhalation tube and the airway humidification tube can only be directly inserted into the endotracheal tube for connection and application. The overflow phenomenon occurs due to the influence of the tracheal intubation; the existing tracheal intubation is integrally structured with the neck fixator and cannot be moved. The position is fixed, and after it is inflated, it will compress the mucous membrane of the fixed part in the trachea. Long-term use will easily cause ischemic necrosis or granulation tissue growth in the compressed tracheal mucosa, which will cause serious consequences and threaten the health of the patient; the existing tracheal intubation The hardness of the material of the tube, the patient end and the tube body is the same, and it directly acts on the tracheal mucosa of the human body, which will damage the patient's cavity mucosa during use.

Therefore, it is necessary to improve the existing tracheal intubation, reduce the pain of the patient and facilitate the use of medical personnel.

In order to achieve the above object, the utility model proposes the following technical solutions:

The tracheal intubation tube includes a tube body, a machine end, a patient end, an infusion tube, an infusion cavity, a balloon, a balloon tube, and a neck immobilizer. Inflatable air bag, the air bag is connected with the air bag tube, at least one infusion cavity is provided in the tube body, one end of the infusion cavity is connected with the patient end, the other end is connected with the infusion tube, and the infusion tube is connected with three Through the pipe, the pipe body is provided with a neck retainer, the neck retainer and the pipe body are in a split structure, the neck retainer is sleeved on the pipe body, and the neck retainer is provided with an adjustment screw, the neck fixer is connected with the pipe body through an adjusting screw.

Further, the end portion of the patient end is made of flexible material.

Further, scales are provided on the outer wall of the tube.

Further, the infusion tube and the balloon tube in the tube body are symmetrically arranged.

The beneficial effects of the utility model:

1. The above-mentioned tracheal intubation is not only beneficial to patients who have retained the tracheal intubation for a long time to perform oxygen inhalation and airway humidification at the same time, but also can effectively ensure that the drug will not overflow when the drug is injected. In addition, the The above-mentioned tracheal intubation also does not need to fix the oxygen inhalation tube and the airway humidification tube during application, thereby effectively saving resources and time of medical personnel.

2. The endotracheal intubation of the present utility model can adjust the depth of the intubation into the trachea, thereby adjusting the position of the air bag attached to the intubation into the trachea, and avoiding the mucosal necrosis or granulation of the tracheal mucosa due to local long-term compression tissue growth.

3. The end part of the patient's end is made of flexible body material, while the rest of the tube body maintains the original rigidity, which keeps the tube body resistant to folding and kinks during endotracheal intubation, and at the same time prevents the patient's end against human tissue during endotracheal intubation Create uncomfortable compression and protect the patient.

detailed description

In order to make the purpose, technical solutions and beneficial effects of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings, so as to facilitate the understanding of technical personnel.

As shown in Figure 1, the tracheal intubation tube includes a tube body 1, a machine end 2, a patient end 3, an infusion tube 4, an infusion chamber 5, a balloon 6, a balloon tube 7, a neck fixator 8, and the tube body 1 is provided with a scale on the outer wall, the machine end 2 is connected with the ventilator, and an inflatable air bag 6 is arranged near the patient end 3, and the air bag 6 is connected with the air bag tube 7, and at least one transmission line is arranged in the tube body 1 Injection cavity 5, one end of the infusion cavity 5 is connected with the patient end 3, and the other end is connected with the infusion tube 4, and the infusion tube 4 is connected with a three-way tube 9, and the infusion tube 4 in the tube body 1 is connected with the balloon The tubes 7 are symmetrically arranged, and the tracheal intubation described above is not only beneficial to the patients who have retained the tracheal intubation for a long time to perform the work of oxygen inhalation and airway humidification at the same time, but also can effectively ensure that the drug will not overflow when the drug is injected In addition, in the application of the tracheal intubation, there is no need to fix the oxygen inhalation tube and the airway humidification tube, thereby effectively saving resources and time of medical personnel.

The pipe body 1 is provided with a neck retainer 8, the neck retainer 8 and the pipe body 1 have a split structure, the neck retainer 8 is sleeved on the pipe body 1, and the neck retainer 8 An adjustment screw 10 is provided on the top, and the neck holder 8 is connected with the tube body 1 through the adjustment screw 10. Since the original tracheal intubation tube and the neck holder 8 are integrally structured and cannot be moved, medical staff cannot adjust its entry. The depth of the trachea makes the position of the airbag 6 attached to the tracheal intubation fixed in the trachea. After inflating, it will compress the mucous membrane of the fixed part in the trachea. Long-term use may easily cause ischemia and necrosis of the tracheal mucosa at the compressed place or internal granulation tissue growth, and then produce serious consequences, threatening the health of the patient, the tracheal intubation tube of the present utility model can adjust the depth of the intubation tube entering the trachea, thereby adjusting the position where the attached air bag 6 on the intubation tube enters the trachea.
