Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical nursing supplies, in particular to an endotracheal tube for preventing unplanned extubation. Background Art
[0002] Endotracheal intubation is mainly used to assist patients in breathing, relieve airway obstruction, aspirate airway secretions, etc. When a patient needs to undergo general anesthesia surgery, or when the patient suddenly experiences respiratory arrest, cannot breathe independently, the airway is compressed, or there are too many airway secretions to be cleared by oneself, resulting in airway obstruction, the patient will experience symptoms such as dyspnea, shortness of breath, cyanosis of the lips, and weakness of the head at this time. It is necessary to assist breathing through endotracheal intubation in time to improve hypoxia.
[0003] Currently, common endotracheal tubes include a tube body, an airbag tube, and a bite block. The bite block is sleeved on the tube body, and the inner end of the airbag tube is connected to the tube body (the outer end of the airbag tube is connected to an airbag). During use, after the tube body is inserted, the patient is asked to keep biting the bite block. At this time, the inner end of the airbag tube is outside the bite block. However, some patients will feel uncomfortable after the tube body is inserted or after the anesthetic wears off, and involuntarily bite the bite block hard, easily biting off the airbag tube connected to the tube body, causing damage to the endotracheal tube and requiring unplanned extubation, and then re-intubation is needed. Summary of the Invention
[0004] The problem to be solved by the utility model is to provide an endotracheal tube for preventing unplanned extubation, which can avoid the patient accidentally biting off the airbag tube and causing unplanned extubation. The adopted technical solution is as follows:
[0005] An endotracheal tube for preventing unplanned extubation includes a tracheal tube body, an airbag tube, and a bite block. The bite block is sleeved on the tracheal tube body, and the inner end of the airbag tube is connected to the tracheal tube body in a communicating manner. The bite block includes a bite tube and a baffle. The characteristic is that: a long strip-shaped protective sleeve is arranged on the inner side wall of the bite tube, the protective sleeve is arranged along the length direction of the bite tube, and the protective sleeve extends from the outer opening of the bite tube to the middle of the bite tube; the airbag tube passes through the protective sleeve from outside to inside, and the inner end of the airbag tube is located in the bite tube.
[0006] A protective sleeve is arranged on the inner side wall of the bite tube to fix the airbag tube in the bite tube, so that the airbag tube is protected by the bite tube; when the patient bites the bite tube, the airbag tube is located inside the bite tube and has no direct contact with the patient, thereby avoiding the patient accidentally biting off the airbag tube and causing unplanned extubation.
[0007] As a preferred embodiment of the present utility model, the bite tube includes a rigid tube body and a soft protective layer, and the soft protective layer is sleeved on the rigid tube body; the protective sleeve is located on the rigid tube body. By sleeving the soft protective layer on the original rigid tube body of the bite tube, it can prevent the patient from biting or even crushing the bite tube and causing damage to the patient's teeth.
[0008] As a further preferred embodiment of the present utility model, the protective sleeve and the rigid tube body are integrally formed.
[0009] As a further preferred embodiment of the present utility model, the soft protective layer is a silicone layer or a rubber layer.
[0010] As a preferred embodiment of the present utility model, the inner section of the bite tube is bent obliquely downward. In order to make the inner section of the bite tube in the oral cavity bend obliquely downward when the patient bites, so that the inner section of the bite tube can fit the patient's tongue root and reduce the discomfort of the patient. The aforementioned inner section of the bite tube refers to the part of the bite tube in the oral cavity.
[0011] In order to make the inner section of the bite tube fit the patient's tongue root more closely, as a further preferred embodiment of the present utility model, the bending amplitude of the inner section of the bite tube is 8 - 12°. In a specific embodiment, the bending amplitude is preferably 10°.
[0012] In order to make the patient more comfortable when biting and reduce the discomfort caused by the inner section of the bite tube to the patient's oral cavity, as a further preferred embodiment of the present utility model, the length of the inner section of the bite tube is 4 - 6 cm. In a specific embodiment, the length of the inner section of the bite tube is preferably 5 cm.
[0013] Compared with the prior art, the present utility model has the following advantages:
[0014] The tracheal intubation of the present utility model for preventing unplanned extubation is provided with a protective sleeve on the inner wall of the bite tube to fix the balloon tube in the bite tube, so that the balloon tube is protected by the bite tube; when the patient bites the bite tube, the balloon tube is inside the bite tube and has no direct contact with the patient, thereby preventing the patient from accidentally biting off the balloon tube and causing unplanned extubation. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 is a schematic structural diagram of a preferred embodiment of the present utility model;
[0016] Figure 2 is Figure 1 a cross-sectional view taken along A - A in
[0017] wherein, each label is: 1 - tracheal tube body, 2 - balloon tube, 3 - bite device, 31 - bite tube, 311 - rigid tube body, 312 - soft protective layer, 32 - retaining piece, 4 - protective sleeve. Detailed implementation manners
[0018] The following further describes in conjunction with the accompanying drawings and the preferred implementation manners of the present utility model.
[0019] As Figure 1 shown, an endotracheal tube for preventing unplanned extubation includes a tracheal tube body 1, an airbag tube 2 and a bite block 3. The bite block 3 is sleeved on the tracheal tube body 1. The bite block 3 includes a bite tube 31 and a baffle 32. The inner section of the bite tube 31 is bent obliquely downward. In order to make the inner section of the bite tube 31 fit the patient's tongue root better, make the patient more comfortable when biting, and reduce the discomfort caused by the inner section of the bite tube 31 to the patient's oral cavity. In this embodiment, the length of the inner section of the bite tube 31 is 5 cm (it can be within the range of 4 to 6 cm), and the bending amplitude is 10° (it can be within the range of 8 to 12°).
[0020] As Figure 1 and Figure 2 shown, the bite tube 31 includes a rigid tube body 311 and a soft protective layer 312. The soft protective layer 312 is sleeved on the rigid tube body 311. The soft protective layer 312 is a silica gel layer or a rubber layer. A strip-shaped protective sleeve 4 is provided on the inner side wall of the rigid tube body 311. The protective sleeve 4 is integrally formed with the rigid tube body 311. The protective sleeve 4 is arranged along the length direction of the bite tube 31. The protective sleeve 4 extends from the outer opening of the bite tube 31 to the middle of the bite tube 31. The airbag tube 2 passes through the protective sleeve 4 from outside to inside. The inner end of the airbag tube 2 is located in the bite tube 31 and is connected to the tracheal tube body 1 in a communicating manner.
[0021] A protective sleeve 4 is arranged on the inner side wall of the bite tube 31 for fixing the airbag tube 2 in the bite tube 31, so that the airbag tube 2 is protected by the bite tube 31. When the patient bites the bite tube 31, the airbag tube 2 is located inside the bite tube 31 and has no direct contact with the patient, thus avoiding the patient accidentally biting off the airbag tube 2 and causing unplanned extubation. And sleeving a soft protective layer 312 on the original rigid tube body 311 of the bite tube 31 can prevent the patient from biting and even biting and crushing the bite tube 31 and causing damage to the patient's teeth.
