New description: [New technical field] The present invention relates to an inflatable device, in particular to a throat inflation device for a tracheal-inner tube airbag. [Prior Art] In the field of respiratory therapy, patients with respiratory failure often use tracheal intubation for emergency treatment, mainly by connecting a balloon to the end of a tube and then extending into the trachea of the patient for gas push. After the balloon is inflated, the following two functions are provided: 1. Positive pressure breathing is provided, and the airway opening of the patient is closed when the airbag is inflated, so when the artificial air is delivered, the gas can be completely delivered to the patient. The lungs are not leaking. 2. Prevention of aspiration pneumonia, because such patients are prone to the possibility of suffocation due to the secretion of the secretions into the lungs or the sputum into the lungs, so by the inflation of the balloon The patient's airway opening Φ. is closed to greatly reduce the possibility of occurrence. - However, because the trachea has its limitations of telescoping, if the balloon is over-inflated after intubation, it may lead to tracheal mucosal necrosis, tracheal stenosis or even tracheal rupture and endanger life. So the key to airbag inflation is how to This is achieved at the lowest airbag pressure, while at the same time avoiding excessive inflation of the airbag and causing damage to the pressure generated by the airway wall. Currently, clinically, a 10 mL syringe is often used for gas push and pressure gauge to avoid the above situation, but it also inevitably requires the medical staff to add extra strength to observe the patient's condition. For the above reasons, how to conceive 3 M413507 An inflatable device that can maintain the airbag at a safe value and immediately relieve pressure when the safety value is exceeded to avoid over-inflation of the airbag is the goal of the new type.

Furthermore, the second end wall 348 of the second shell portion 4 has a supporting convex portion (10) facing the inner wall surface of the second shell portion space 341 and protruding from the inner wall surface 345, and the convex state is supported by the pressure relief. The barrier body 41 of the valve 4 is such that the barrier body 41 is spaced apart from the inner wall surface 345' of the second end wall 348. Therefore, it can be seen from FIG. 4 that the barrier body 41 is normally closed to the opening-opening 342, and the second opening 343 is borrowed. The support protrusions (10) are supported by the barrier body 41 of the pressure relief valve 4 to maintain a normally open relationship. In the present embodiment, the elastic member 43 of the pressure relief valve 4 is a spring and has a modulus of elasticity, and thereby closes the barrier body 41 to normally close the second gas flow passage 32, when the gas pressure in the communication tube 3 exceeds At the elastic coefficient of the elastic member 43, at this time, the elastic member 43 is compressed to interlock the barrier body 41 to open the closed first opening 342 to communicate with the open second gas flow path 32, and simultaneously push the barrier body 41 to the second. The opening 343 is opened to allow the gas in the communication pipe 3 to escape from the outside through the second opening 343. Preferably, the first shell portion 33 is formed with a third opening 349 that communicates with the first shell space 331 and the outside. The connecting tube 3 further includes a third opening 349 and a pressing portion corresponding to the pressure relief valve 4. The gland 37 of the cover cap 37 is pressed and deformed to interlock the pressing portion 42 of the pressure relief valve 4. It should be particularly noted that, in this embodiment, the first opening 342 is a cross-shaped opening slightly larger than the pressing portion 42, and the pressing portion 42 is located at the center of the first opening 342, and the pressing portion 42 is exposed and exposed. Further, it is convenient to carry out the manual (4) by the gland 37. Further, the first opening 342 is not blocked by the pressing portion 42, that is, the path of the gas entering the first gas channel 31 is further used to push the blocking body 41 to drive. The effect of compressing the elastic member 43 to relieve pressure. In addition, in order to allow the user to easily observe the pressure value in the endotracheal tube airbag 7, the present invention further includes a pressure measuring device 5 disposed on the first shell 胄 33 and used to measure the pressure of the first shell space 331 Since the first shell portion 33 communicates with the gas official inner balloon 7, the internal pressure values are equal, so that the pressure value in the intratracheal balloon 7 can be conveniently observed by the pressure measuring device 5. On the other hand, since the flexible ball 22 of the air supply member 2 is not supportive, it is easy to cause a wrong pressure. Therefore, the present invention provides a cover member 6 that is wrapped around the communication tube 3 to avoid the occurrence of such a problem. The cover member 6 includes a main body portion 61 for receiving the first shell portion 33 of the communication tube 3, and an extension portion 62 extending from the main body portion 61 and attached to the flexible sphere 22 of the air supply member 2, and The support of the extension section 62 allows the flexible ball 22 to be less susceptible to pressure, and at the same time provides support for the flexible ball 22 when pressed. Referring to Figures 1, 5 and 6', the present invention is used by first connecting the endotracheal tube 7 through the second tube portion 36 of the communication tube 3, and by squeezing the flexible sphere 22 of the air supply member 2 The gas is output to the endotracheal tube balloon 7 to be inflated. In general, the optimum pressure value of the endotracheal tube airbag 7 is less than M413507 30 cmH2 〇 (cm water column), so that the elastic modulus of the elastic member 43 of the pressure relief valve 4 in the present embodiment is set corresponding to the pressure value. When the foregoing air supply member 2 continuously outputs the gas to the endotracheal tube airbag 7, the pressure in the first gas flow path 会 increases, and at the same time, the first opening 342 enters the second gas flow path 32, but this The gas entering is blocked by the elastic member 43 and cannot enter the second gas flow path 32 until the gas pressure in the communication tube 3 exceeds the elasticity, and the elastic element 43 is compressed to open the second. The gas flow path 32, at the same time, pushes the barrier body 41 to open the second opening 343, so that the gas pressure in the communication tube 3 is released to the outside, so that the intraductal gas can be avoided as in the conventional t 7 Over-inflated problem. Further, in addition to the above-described automatic pressure release method, the user can also perform manual 9 pressure by pressing the pressing cover 37 of the communication tube 3 to press and deform the pressing portion 42 of the pressure relief valve 4, and similarly, it is possible to avoid The problem of over-inflation of the endotracheal tube balloon 7 occurs. It should be particularly noted that the elastic member 43 of the present invention can be replaced according to different needs. For example, a long-term intubator may require higher pressure to avoid breathing, so the pressure relief value can be set to be higher. 4〇cmH2〇, at this time, as long as the elastic element 43 corresponding to the pressure release value is placed in the replacement 'can achieve the original automatic (four) effect, it is convenient for the nursing staff to make appropriate adjustments and reduce the damage of excessive inflation ^ again, if When used in a laryngeal mask (not shown), the more flexible pressure value of 6〇cmH2〇 can be applied. (4) The elastic piece 43 corresponding to the value of (10) can be replaced to meet the requirements for safe use: The above-mentioned 'new artificial airway airbag inflator is used; the voltage between the four sets allows the user to select the manual or automatic method for the air pipe 10 M413507 according to the requirements.
