Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a novel endotracheal cannula. Background Art

[0002] Endotracheal intubation is a clinical technique that passes a special tube from the mouth and nasal cavity through the pharynx and into the trachea through the glottis. It can provide patients with oxygen to maintain oxygenation and ensure airway patency. It is mainly used for patients with respiratory failure who need endotracheal intubation and mechanical ventilation.

[0003] Currently in clinical practice, ICU patients are often intubated and mechanically ventilated for more than 48 hours for disease treatment. Some patients with severe pneumonia and ARDS are even intubated for more than a week or longer. Also, due to the long-term compression of the endotracheal tube and air bag on the mouth, tongue, throat, airway mucosa, vocal cords, etc., patients will experience a series of complications after extubation, such as laryngeal edema, pharyngeal pain, foreign body sensation, hoarseness, etc. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a novel endotracheal tube, which solves the problem of edema, pain and other irritating diseases caused by the existing endotracheal tube compressing the same area for a long time.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A novel endotracheal cannula is provided, comprising a cannula body, the cannula body comprising a cannula tube body, one end of the cannula tube body is provided with a joint, the insertion end thereof is provided with an airbag assembly, the airbag assembly is provided with three groups, including a first airbag, a second airbag and a third airbag, the first airbag is connected to a first branch tube, the second airbag is connected to a second branch tube, and the third airbag is connected to a third branch tube; the first branch tube, the second branch tube and the third branch tube are all provided with a pressure assembly; and the cannula tube body is provided with a fixing assembly.

[0007] The beneficial effects of adopting the above technical solution are as follows: the connector is used to connect to an external ventilator, and then the first airbag is inflated through the first branch tube, the second airbag is inflated through the second branch tube, and the third airbag is inflated through the third branch tube. When the airbag is inflated, the ventilation capacity can be effectively improved and the airbag can be sealed. The multiple sets of airbag components can be used crosswise, and filling in different time periods can reduce the pressure on the tracheal wall, avoid long-term pressure of the tracheal intubation on the same area, and thus reduce irritation complications such as edema and pain caused by surgery; the pressure component can detect the pressure of the airbag to avoid under-inflation or over-inflation of the airbag; and the fixing component can fix the tracheal intubation and the patient's head separately during use to avoid tracheal instability and secondary damage to the patient's tracheal wall.

[0008] Furthermore, the first airbag, the second airbag and the third airbag are all rectangular, and the vertices thereof are configured to be arc-shaped.

[0009] The beneficial effects of adopting the above technical solution are: the rectangular airbag can reduce its footprint in the endotracheal tube, increase the number of airbags used, and the arc-shaped design of the apex of the rectangular airbag can reduce the pressure or scratching of the tracheal wall by the airbag.

[0012] Furthermore, a branch pipe groove is provided on the inner wall of the cannula body.

[0013] The beneficial effects of adopting the above technical solution are: the branch tube groove is used to place the first ventilation tube, the second ventilation tube and the third ventilation tube, which can reduce the risk of rupture of the intubation channel and improve the safety of use, while also reducing the pressure on the tracheal wall and reducing complications such as edema and pain caused after surgery.

[0014] Furthermore, the cannula body is provided with scales, and the insertion end thereof is provided with a through hole.

[0015] The beneficial effects of adopting the above technical solution are as follows: the scale set on the tube body can timely determine the insertion depth of the endotracheal tube during the operation to avoid inserting too deep and mistakenly entering the bronchus, causing hypoxia and atelectasis on one side; and the through hole set at the insertion end can increase the ventilation flow, and when the main opening of the endotracheal tube is blocked by the tracheal wall, airflow can still be generated through the through hole.

[0016] The beneficial effects of adopting the above technical solution are: the pressure component includes pressure sensors arranged on the inner walls of the first airbag, the second airbag and the third airbag, and the pressure sensors are connected to the automatic inflator.

[0017] The beneficial effects of adopting the above technical solution are as follows: the pressure sensor can continuously record the balloon pressure of the endotracheal tube. When it is under-inflated, it can be inflated in time through the automatic inflator to avoid the risk of aspiration caused by insufficient inflation of the endotracheal tube during use; and when it is over-inflated, it can be exhausted in time through the automatic inflator to avoid the dangers of tracheal mucosal ischemia, necrosis, etc.

[0018] Furthermore, the fixing assembly includes a strap and a fixer connected to the strap, the fixer includes a fixing plate, an upper baffle and a lower baffle arranged inside the fixing plate, the upper baffle and the lower baffle are connected by a first support column and a second support column, the first support column is provided with a first fastener and a second fastener, and the second support column is provided with a third fastener and a fourth fastener.

[0019] The beneficial effects of adopting the above technical solution are: the patient's head can be fixed to the fixing component by the strap to improve the stability of the endotracheal tube, and the fixator can fix the endotracheal tube, and the height of the upper baffle and the lower baffle can be adjusted by the first support column and the second support, so that the fixing component can adapt to endotracheal tubes of different diameters.

[0020] Furthermore, a slide groove is provided on the side of the fixing plate; the first fastener, the second fastener, the third fastener and the fourth fastener all include a sleeve and a fastening column connected to the sleeve; the fastening column passes through the slide groove, and a knob is connected to one end thereof.

[0021] The beneficial effects of adopting the above technical solution are: the first fastener and the second fastener can fix the two sides of the upper baffle respectively, and the third fastener and the fourth fastener can fix the two sides of the lower baffle; and the slide groove can enable the fastener to move up the support column through the sleeve, thereby adjusting the height of the upper baffle and the lower baffle to adapt to air pipes of different diameters.

[0022] Furthermore, the upper baffle and the lower baffle are both U-shaped.

[0023] The beneficial effect of adopting the above technical solution is that the upper baffle and the lower baffle, both of which are U-shaped, can fit the endotracheal tube during use and can be adjusted and fixed according to the size of the endotracheal tube.

[0024] In summary, the novel endotracheal tube provided by the utility model has the following beneficial effects:

[0025] (1) The endotracheal tube is equipped with multiple groups of airbag components, which increases the number of traditional airbags and can achieve cross-filling in different time periods, thereby reducing the pressure on the tracheal wall and avoiding long-term pressure on the same area by the endotracheal tube, thereby reducing irritation complications such as edema and pain caused by surgery.

[0026] (2) The shape of the airbag group is set to be rectangular, which can increase the number of airbags used, and the arc-shaped design of the apex of the rectangular airbag can reduce the pressure or scratching of the tracheal wall by the airbag.

[0027] (3) The multiple branches of the endotracheal tube are all arranged in the same branch tube groove, which can reduce the risk of rupture of the tube channel and improve the safety of use. At the same time, it also reduces the pressure on the tracheal wall and reduces complications such as edema and pain caused by surgery.

[0028] (4) The pressure component of the endotracheal tube can detect the inflation pressure and inflate or exhaust the gas in a timely manner according to the pressure to avoid under-inflation or over-inflation that may cause harm to the patient.

[0029] (5) The fixing assembly of the endotracheal tube can fix the endotracheal tube to the patient's head separately during use, thereby preventing tracheal instability from causing secondary damage to the patient's tracheal wall. BRIEF DESCRIPTION OF THE DRAWINGS
