Description

A medical T-tube

technical field

The invention relates to the field of medical instruments, in particular to a medical T-shaped tube.

Background technique

At present, clinically, the application of T-tube to treat airway stenosis is more common. The T-shaped silicone tube has good elasticity and toughness, can effectively reduce the irritation to the airway mucosa, is easy to fix, and is not easy to cough up when coughing; it has good tissue compatibility, strong support, and non-toxic, and does not affect the patient when the tube is worn Daily life; after long-term contact with the trachea, its compliance has no significant change, so it is preferred by clinicians and patients. Since the side hole can be fixed at the tracheostomy, the endotracheal part without the stent exerts pressure on the airway to strengthen the fixation, and does not affect the return of blood and lymph. The T-tube stays in place for up to 20 years and is also easy to remove in an emergency. The operation of T-tube insertion is relatively simple and safe, and most cases can be managed through a tracheostomy under general anesthesia and sedation. Compared with tracheal reconstruction, no special care is required after T-tube placement, but adequate sedation and careful care are required after tracheal reconstruction, and improper management of postoperative patients may be life-threatening. At present, the T-tube plays an increasingly important role in the treatment of tracheal stenosis.

In the process of realizing the present invention, the inventors found that there are at least the following defects in the prior art: when the T-shaped tube in the prior art is in use, granulation tissue hyperplasia is prone to occur due to the long-term contact between the inner wall of the T-shaped tube and the throat, And there will be dry scab blockage in the tube and vocal cord edema. In addition, when the ventilator is used to deliver air to the T-shaped tube, the airflow will enter the upper and lower ends of the T-shaped tube along with the pipe, but the original intention of medical use is to let the airflow enter the lower end of the T-shaped tube, and if it enters the upper end, it will cause air leakage. This prevents the airflow from entering the lungs intact. Even after the airflow enters the lower end, it will float upwards due to the low density of the airflow and leak out through the outside of the T-shaped tube, thereby affecting the therapeutic effect.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

comparative example

As shown in Figure 1, it is a medical T-shaped tube in the prior art. The existing T-shaped tube is a rubber T-shaped tube, and one end is provided with a ventilator nozzle, and an airflow valve is provided at the nozzle position. The T-shaped tube with this structure is ventilated by a ventilator during treatment, and the airflow enters the mouth of the ventilator and then enters the main body of the T-shaped tube. The tube wall of the main body of the T-tube overflows at the upper and lower ends, but the correct medical method is to let the airflow enter the trachea from the lower end, so this will cause the leakage of the airflow, thereby failing to achieve the expected therapeutic effect.

Example 1

As shown in Figure 2, it is a medical T-shaped tube provided by the present invention, the middle right end of the T-shaped tube body (1) is provided with a ventilator nozzle (2), and the upper end of the T-shaped tube body (1) The periphery is covered with an outer shrinkable airbag (4), and the inner upper side of the T-shaped tube body (1) is provided with an inner shrinkable airbag (3), and the inner shrinkable airbag (3) and the outer shrinkable airbag (4) Both are connected with an airflow pipe (5), the airflow pipe (5) is used to connect with the airflow generator, the end of the airflow pipe (5) is provided with an airflow valve (6), and the airflow valve (6) is connected to At the position of the mouthpiece (2) of the ventilator.

In the non-working state, the outer contraction air bag (4) and the inner contraction air bag (3) are in a shriveled state, and are close to the tube wall of the T-shaped tube main body (1). When in use, first connect the airflow tube (5) with the airflow generator, inflate the airflow tube (5), and when the outer contraction airbag (4) and inner contraction airbag (3) reach the predetermined size, Disconnect the airflow generator, and then close the airflow valve (6) so that the two airbags are inflated. Connect the ventilator nozzle (2) to the ventilator, and then perform ventilation. At this time, the air flow enters the T-shaped pipe main body (1), because the upper end of the T-shaped pipe main body (1) is blocked by the inner contraction air bag (4), so the air flow can only enter downward along the inner pipe wall. When the air flow comes out from the lower nozzle, the air flow will float upwards along the outer tube wall, because the outer upper end of the T-shaped tube body (1) is blocked by the outer contraction air bag (4), so the air flow can only enter downwards , so as to avoid air leakage.

Example 2

Human breathing action is always present. Even when using a ventilator for ventilation, people will breathe instinctively. This action will cause the contraction and expansion of the trachea, which will cause problems with the leakage prevention of the external contraction airbag. The balance airbag can be set to replenish or inhale air according to the state of the breathing action. When the trachea is constricted, the external contraction air bag will be squeezed, and at this time, the balance air bag will inhale, so that the trachea will not be compressed by the external contraction air bag. When the trachea is dilated, there will be gaps around the outer contraction airbag, which cannot completely prevent airflow leakage. At this time, the balance airbag can be inflated to prevent airflow leakage.

Example 3

As shown in Figure 4, the overall structure of the medical T-tube is the same as that of Example 1, the surface of the T-tube main body (1) is provided with a scale, and the mouth of the ventilator ( 2) The intersection of the extension line of the central axis and the T-shaped tube body (1) is set as a 0 scale, above the 0 scale is a positive scale number, and below the 0 scale is a negative scale number, and the scale The unit length is 1mm. When treating a patient, it is usually necessary to adjust the length of the medical T-tube according to the actual condition of the patient, including the length of the upper end and the lower end of the ventilator nozzle, so a scale is set on the surface of the T-tube, which can Accurately obtain T-tubes that fit the patient's length.

Such a connection method can inflate the air bag faster, making the treatment more convenient and fast.

Example 8

As shown in Figure 6, the overall structure of the medical T-tube is the same as that of Example 1, and the airflow tube (5) is two separate airflow tubes, one of which is connected to the external contraction airbag (4) , a connecting inner contraction air bag (3). In this way, the external contraction air bag (4) can be independently controlled, so that the T-shaped tube can be adapted to more sizes of trachea, and the size of the internal contraction air bag (3) will not be affected, and normal breathing will not be affected.

Example 9
