Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a safe plastic tracheotomy cannula device capable of retaining a closed subcutaneous tunnel, which is suitable for almost all people who need to remove the tracheotomy cannula in clinical practice. Background Art

[0002] In the clinic, some patients need to undergo tracheotomy and indwelling tracheostomy tube surgery for various reasons. These patients may need to remove the tracheostomy tube later due to improvement in their condition and resume normal oral and nasal ventilation. Long-term indwelling of tracheostomy tubes can cause tracheal stenosis related to various reasons, such as edema of the glottis or subglottic area, local scar stenosis, local granulation, tracheal collapse caused by cartilage damage, local ulcers or necrosis, etc. Among them, the tracheal stenosis of a small number of tracheotomy patients is very hidden, making it difficult to detect before extubation. Related reports suggest that factors such as obesity, slow response, and communication disorders in patients are more likely to make hidden tracheal stenosis difficult for doctors to detect. Therefore, after the routine removal of the tracheostomy tube, these patients will subsequently experience acute dyspnea or even suffocation and need further rescue, and the original tracheotomy has been reduced or closed due to the removal of the tracheostomy tube. At the same time, these patients with hidden symptoms often have difficult intubation and many underlying diseases, which increases the difficulty of emergency rescue and the risk of accidental suffocation. Summary of the invention

[0003] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a safe plastic tracheotomy tube device that can retain a closed subcutaneous tunnel. The present invention solves the above-mentioned difficult clinical problems, and reserves a subcutaneous tunnel in the tracheal cavity in advance for the people who need to remove the tracheotomy tube, and is equipped with a sealing plug. After the actual removal of the tube, it does not affect the patient's normal ventilation and pronunciation through the mouth and nose, and at the same time reserves an emergency breathing channel for possible rescue. It is suitable for almost all people who need to remove the tracheotomy tube in the current clinic, greatly ensuring the safety of patients after removal of the tube, and has the characteristics of simplicity and easy operation.

[0004] The technical solution adopted by the present invention is:

[0005] A safe plastic tracheotomy cannula device capable of leaving a closed subcutaneous tunnel, characterized in that it comprises:

[0006] The subcutaneous tunnel body is a hollow structure. The upper part of the subcutaneous tunnel body is provided with an external tracheal fixing part. The shape of the external tracheal fixing part is similar to the fixing part of a symmetrical wing. The fixing part is attached to the human neck to achieve external fixation; the lower part of the subcutaneous tunnel body is provided with an intratracheal fixing part. The intratracheal fixing part is a retractable butterfly-wing-like fixing device. The butterfly-wing-like fixing device is adjusted by a traction rope placed on the side wall of the subcutaneous tunnel body. When the traction rope is tightened, the middle part of the butterfly-wing-like fixing device is folded up to form a butterfly-wing-like buckle structure, which is left in the tracheal cavity to play an internal fixation role for the subcutaneous tunnel body; when the traction rope is loosened, the middle part of the butterfly-wing-like fixing device slides down and adheres to the side wall of the flexible tracheotomy cannula, and the subcutaneous tunnel body can be smoothly taken out;

[0007] A removable subcutaneous tunnel sealing plug is inserted at the upper end of the subcutaneous tunnel body after the subcutaneous tunnel is indwelled, so as to seal the subcutaneous tunnel body;

[0008] The flexible ventilator cannula is a hollow structure, and the flexible ventilator cannula is inserted into the subcutaneous tunnel body. The head end of the flexible ventilator cannula is a ventilator applicable port, which can be routinely connected to the ventilator as needed after the patient's condition changes;

[0009] And a plastic inner core is inserted into the flexible tracheal incision cannula and is used to support the flexible tracheal incision cannula so that the subcutaneous tunnel body can be smoothly placed into the tracheal cavity.

[0010] Furthermore, the butterfly-wing-like fixing device includes a circular ring, and a telescopic structure is arranged between the circular ring and the lower end of the subcutaneous tunnel body (1). The telescopic mechanism includes two symmetrically arranged telescopic rods, each of which includes a first connecting rod and a second connecting rod. One end of the first connecting rod is connected to the circular ring, and the other end is hinged to one end of the second connecting rod. The other end of the second connecting rod is connected to the lower end of the subcutaneous tunnel body.

[0011] Furthermore, each of the telescopic rods is correspondingly provided with the traction rope, one end of the traction rope is connected to the connection between the first connecting rod and the circular ring, and the other end passes through the fixing part and is exposed above the fixing part.

[0012] Furthermore, the flexible hollow air cutting sleeve is made of flexible plastic material.

[0013] Furthermore, the subcutaneous tunnel body and the flexible pneumatic incision cannula are both made of plastic material.

[0014] Furthermore, the plastic inner core is made of hard plastic material.

[0015] Furthermore, the subcutaneous tunnel sealing plug is made of silicone material.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The present invention is applicable to almost all people who need to remove the tracheotomy tube in clinical practice, greatly ensuring the safety of patients after the tube is removed, and has the characteristics of simplicity and easy operation.

[0018] 2. The present invention aims at the high-risk asphyxiation population who need to have the tracheotomy tube removed in clinical practice. The present invention innovatively adds a butterfly-wing-like endotracheal fixation device to the conventional tracheotomy tube device. When the patient needs to have the tracheotomy tube removed, the subcutaneous tunnel can be fixed in the tracheal cavity by pulling the traction rope retained outside the body and opening the fixation device, thereby retaining the patient's emergency breathing passage, greatly improving the safety of such population after extubation, and providing a breathing passage for possible rescue in the later stage. The present invention can be applied to almost all the population who need to have the tracheotomy tube removed in clinical practice, and the operation is simple and easy to use.

[0019] 3. The present invention innovatively abandons the balloon anti-leakage device of the traditional tracheotomy cannula. The main function of the balloon anti-leakage device of the traditional tracheotomy cannula is to ensure effective and sufficient ventilation when the patient receives ventilator treatment, and the presence of the balloon will prevent the tracheotomy cannula from entering the main structure, making it difficult to insert the tracheotomy cannula during rescue. In addition, the condition of almost all people who need to remove the tracheotomy cannula is relatively stable. As long as the tracheotomy is reopened, the problem of dyspnea can be solved, and there is no need for ventilator treatment. Therefore, the present invention abandons the design of the balloon, which improves clinical practicality and makes clinical operation faster and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
