Background technique

Endotracheal intubation is often used for emergency and resuscitation of critically ill patients, mechanical ventilation for respiratory failure, and general anesthesia surgery. This technology can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration, etc. It is one of the most widely used, most effective and efficient means in airway management.

Clinically, for patients who cannot breathe normally, it is necessary to cut the trachea and insert an auxiliary intubation to help the patient breathe. When the patient's condition is relieved and the patient's breathing condition is tested, the endotracheal tube needs to be blocked. Before pulling out the trachea, the outer tube will try to seal the tube gradually, and it can be pulled out after the patient's emotional stability and complete adaptation. However, due to the lack of corresponding medical appliances and equipment, most of the clinical materials are obtained locally, and some simple methods are used to block them. At present, the clinical tracheal tube occlusion operation has the following disadvantages: (1) It is uncomfortable, unsightly, and increases the psychological burden of patients.

Detailed ways

In order to describe in detail the technical content, achieved objects and effects of the present invention, the following descriptions are given with reference to the embodiments and the accompanying drawings.

The most crucial concept of the present utility model is: a tracheal tube plugging device with a conical cavity main body is designed, the inner diameter of the plugging tube can be applied to various types of tracheal tubes with inner diameters, and the cover body can be opened and closed at any time, and can be adjusted ventilation size.

The first embodiment of the present utility model is: a tube blocking device suitable for various types of tracheal tubes, as shown in FIG. It has a truncated cone-shaped structure with a hollow interior. One end of the tube body 1 facing the cover body 2 is a large circular end, and the other end is a small circular end.

The outer diameter of the large circular end of the tube body 1 is 16.5 mm, and the outer diameter of the small circular end is 4 mm, so that the pipe blocking device of the present invention can be adapted to different types of tracheal tubes commonly used in the prior art.

The longitudinal section of the tube body 1 is stepped, and the width difference between two adjacent steps is 1mm, which is suitable for the specification design rules of conventional types of tracheal tubes in the prior art, so that it can better fit with different types of tracheal tubes. . It can also be designed in the most commonly used sizes, such as 7mm, 8mm, 9mm, 10mm, 12mm and 14mm.

As shown in FIG. 2 , the cover body 2 is composed of pins 3 and sealing sheets 4 . The cover body 2 is provided with a fan-shaped through hole; the sealing sheet is a fan-shaped body with a protrusion 5 on the upper part; the cover body 2 is coaxially connected with the sealing sheet 4 through a pin 3 . The cover body 2 can adjust the ventilation amount through the shielding degree of the through hole by the sealing sheet 4 . Setting the protrusion 5 can make the operation process easier.

When the medical staff uses the plugging tube to block the tracheal tube, the cover body 2 can be closed first, and then the small round surface end of the tube body 1 can be inserted into the tube mouth of the catheter. If it is necessary to detect the patient's trachea and breathing state, the cover body 2 can be directly opened for operation. The degree of ventilation of the tracheal tube can also be adjusted by the blocking degree of the sealing sheet 4 above the cover body 2, so that the patient gradually adapts to the breathing state and reduces the discomfort during the test.

The second embodiment of the present utility model is: a pipe blocking device suitable for various tracheal catheters, the only difference between it and the first embodiment is: as shown in FIG. 2, silicone rubber is used as the material of the pipe body 1, The pipe body 1 can be directly made into a frustum-shaped structure.
