During clinical anesthesia or emergency treatment, a tracheal tube is usually inserted into the trachea of a patient to establish an artificial airway. By injection through the injector, the cuff of the tracheal catheter is inflated to press the tracheal wall of the patient. The pressure in the cuff can only be judged by the sense and experience of a doctor and cannot be ensured to be within a proper pressure range (15 cmH 2O-25 cmH 2O). When the pressure is lower than the standard range, the gas in the catheter leaks out of the body from the outside of the catheter, which causes insufficient tidal volume, leakage of anesthetic gas, even flow of vomit, blood and oral secretion into the trachea, and accidental danger.

Referring to fig. 1, an endotracheal tube provided in an embodiment of the present application will now be described. The embodiment of the present application provides an endotracheal tube 1, and in this embodiment, endotracheal tube 1 includes: a tubular body 10, an air inlet tube 20 and a pressure measuring assembly 30. The tracheal catheter 1 is provided with a tube body 10 as a main body portion, an air inlet 11 and an air outlet 12 are respectively formed at two ends of the tube body 10, and an air bag 13 is arranged on one side of the tube body 10 having the air outlet 12. The air inlet 11 and the air outlet 12 are for supplying oxygen to a patient, and are connected to a ventilator or the like through the air inlet 11, and supply oxygen to the air inlet 11 through the ventilator, thereby reaching the air outlet 12, and discharging the oxygen from the air outlet 12. Further, an airbag 13 is provided on the side of the tube 10 having the outlet 12. In order to ensure that the air-oxygen mixture introduced into the tube body 10 can completely enter from the trachea of the patient during the use of the endotracheal tube 1, it is necessary to ensure a certain sealing property between the tube body 10 and the trachea of the patient. For this reason, stretch into endotracheal tube 1 in patient's trachea after, through the size of adjusting gasbag 13, make the outer wall of gasbag 13 and the tracheal inner wall laminating of patient, play certain sealed effect, guarantee that the gas that gets into by air inlet 11 can enter into patient's trachea completely, one side at body 10 is provided with intake pipe 20, intake pipe 20 just is used for letting in gas for gasbag 13 and inflates the processing as communicating with gasbag 13, at this in-process, intake pipe 20 is connected with gasbag 13 alone, intake pipe 20 does not communicate with the inside cavity of body 10. In the using process, the tube body 10 is used for conveying gas towards a patient, such as air-oxygen mixed gas, anesthetic gas and the like, in order to avoid the gas from leaking out when entering the trachea of the patient, the size of the air bag 13 can be adjusted through the air inlet pipe 20, when the air bag 13 is inflated to be attached to the inner wall of the trachea of the patient, the air bag 13 and the inner wall of the trachea form a certain sealing structure, and the gas input by the closing device 10 can completely enter the body of the patient.

In the process of inflating the air bag 13, in consideration of the comfort of the patient, and in order to avoid tissue ischemia, extravasated blood, edema and the like caused by the overlarge air bag 13, and even cause necrosis, erosion, hemorrhage or perforation of the tracheal wall, a pressure measuring assembly 30 is further arranged in the application, the pressure measuring assembly 30 is arranged on the air inlet pipe 20 and communicated with the air inlet pipe 20, and the pressure measuring assembly 30 detects the air pressure state in the air inlet pipe 20. The pressure measuring assembly 30 detects the air pressure in the air inlet pipe 20, the air inlet pipe 20 is communicated with the air bag 13, and the air pressure in the air inlet pipe 20 is consistent with the air pressure in the air bag 13. The air pressure in the air inlet pipe 20 detected by the pressure measuring assembly 30 is the air pressure in the air bag 13. When the air inlet pipe 20 is ventilated into the air bag 13, the air pressure in the air bag 13 is increased, and at this time, the change of the air pressure in the air bag 13 can be observed by observing the pressure measuring module 30. When the air pressure in the air bag 13 reaches a set value, the air inlet pipe 20 is controlled to stop air inlet, and the air bag 13 stops inflating and is attached to the inner wall of the trachea of the patient, so that tissue ischemia, extravasated blood, edema and the like cannot be caused excessively.

In the above embodiment, in order to ensure the detection effect of the pressure measurement assembly 30 on the air bag 13, optionally, the pressure measurement assembly 30 includes an electronic pressure measurement instrument 31, the electronic pressure measurement instrument 31 is communicated with the air inlet pipe 20, and the electronic pressure measurement instrument 31 detects the air pressure state in the air inlet pipe 20. Wherein, electron load cell 31 can realize through display screen, circuit board and pressure sensor, through the atmospheric pressure in the pressure sensor monitoring intake pipe 20 to give the circuit board with information transmission, show on the display screen after handling, with this monitoring to atmospheric pressure of completion. Among them, electronic load cell 31 compares in physical load cell, and it detects more accurately, easily reads, and the function is extensible.

When the electronic load cell 31 is used in the case of a long-term operation, the battery may be exhausted and measurement may not be performed. For this reason, in the present embodiment, optionally, the pressure measuring assembly 30 further includes a physical pressure measuring instrument 32, the physical pressure measuring instrument 32 is also communicated with the air inlet pipe 20, and the physical pressure measuring instrument 32 detects the air pressure state in the air inlet pipe 20. The physical pressure measuring instrument 32 may be a pressure measuring instrument such as a pressure gauge for measuring pressure by a physical method, and the like, and the pressure is directly displayed by a pointer without using a battery or the like, so that long-time monitoring can be realized, for example, the pressure measuring instrument is applied to an ICU ward, a medium-large operation and the like. In addition, the electronic pressure gauge 31 and the physical pressure gauge 32 are used in a matching manner, so that the air pressure in the air inlet pipe 20 can be monitored at the same time, the comparison of the results of the electronic pressure gauge and the physical pressure gauge is facilitated, the use is more accurate and easier to read, and the use is safer and more reliable; after the battery of the electronic pressure measuring instrument 31 is exhausted, pressure measurement can be realized through the physical pressure measuring instrument 32, so that long-time use is realized, and the problem of insufficient endurance time of the electronic pressure measuring instrument used alone is solved.

When the electronic load cell 31 and the physical load cell 32 are provided at the same time, in order to ensure that the electronic load cell 31 and the physical load cell 32 simultaneously keep the pressure measurement in the air inlet pipe 20 consistent, optionally, the electronic load cell 31 and the physical load cell 32 are integrated into a whole, and the load cell assembly 30 is communicated with the air inlet pipe 20 through the three-way pipe 21. It can be understood that the three-way pipe 21 is arranged on the air inlet pipe 20, and the three-way pipe 21 additionally extends out of the air inlet pipe 20 and is simultaneously communicated with the electronic pressure measuring instrument 31 and the physical pressure measuring instrument 32, so that the monitoring synchronism and accuracy of the electronic pressure measuring instrument 31 and the physical pressure measuring instrument 32 are ensured.

In the above embodiment, in order to ensure the accuracy of the measurement of the pressure measuring assembly 30 on the air inlet tube 20 and avoid the air inlet tube 20 being arranged on the tube body 10 to obstruct the catheter from entering the oral cavity of the patient, the air inlet tube 20 is optionally arranged on one side of the tube body 10 close to the air inlet. Therefore, when the tracheal catheter 1 enters the trachea of a patient and the air bag 13 is attached to the inner side of the trachea of the patient, the joint of the air inlet pipe 20 and the tube body 10 is still positioned at the outer side of the oral cavity of the patient, and the interference to the patient is avoided. In addition, a ventilator connector 14 may be generally disposed at the air inlet 11 of the tube 10 to facilitate connection of the endotracheal tube 1 with a ventilator, so that air in the ventilator is introduced into the patient's trachea from the endotracheal tube 1.

It should be noted that the air bag 13 is separately separated from the tube body 10, that is, the air bag 13 alone constitutes a cavity and is in communication with only the air inlet tube 20. For this reason, in this embodiment, optionally, the air bag 13 is sleeved on the outer wall of the tube 10, and the air bag 13 is fixedly connected with the tube 10. In order to prevent the air bag 13 from moving relative to the tube 10 when entering the patient's trachea, the air bag 13 is usually adhered to the tube 10, or the air bag 13 directly serves as an extension of the outer wall of the tube 10, the air bag 13 is integrally provided with the tube 10, and the air bag 13 and the tube 10 are spaced apart from each other to form different air guide channels. In addition, in order to ensure the reliability of the support of the air bag 13 to the trachea of the patient during inflation, the air bag 13 should be sleeved on the outer wall of the tube body 10, and the air bag 13 is in an annular state after inflation, so that the outer wall of the annular air bag 13 can be attached to the trachea of the patient.

Correspondingly, the air bag 13 is communicated with the air inlet pipe 20 but not communicated with the tube body 10, the air inlet pipe 20 is arranged on one side of the tube body 10, in order to avoid the damage of the air inlet pipe 20 to the trachea of a patient when the catheter enters the trachea, the air inlet pipe 20 is usually arranged inside the tube body 10, namely, optionally, the tube body 10 and the air inlet pipe 20 are of an integrated structure, so that the air inlet pipe can be conveniently inserted into and pulled out of the trachea of a human body, and the air inlet pipe 20 alone forms an air passage inside the tube body 10 and is only communicated with the air bag 13 outside the tube body 10. Thus, the gas filled in the inlet tube 20 can directly enter the air bag 13 through a separate air passage, and is prevented from mixing with the gas inside the tube body 10. It should be noted that, one end of the air inlet pipe 20 extends out of the tube body 10, the other end of the air inlet pipe 20 is communicated with the air bag 13 at the other end of the tube body 10, and the air bag 13 is disposed on the outer wall of the tube body 10, so that both ends of the air inlet pipe 20 can be regarded as extending out of the tube body 10, and the effectiveness of gas transmission can be ensured by performing a sealing process between the air inlet pipe 20 and the tube body 10.

On the basis of the above embodiment, the present embodiment further provides a ventilator system, which includes a ventilator, an air injection member and the above-mentioned endotracheal tube 1, wherein the ventilator is communicated with the air inlet 11 of the endotracheal tube 1, and the air injection member is communicated with the opening of the air inlet tube 20 of the endotracheal tube 1, so as to inject air toward the air bag 13.

It should be noted that the endotracheal tube in this embodiment is the same as the endotracheal tube in the above embodiments, and the specific structure thereof is the same, and the technical effects in this embodiment are also the same, which are not described herein again.

The present application is intended to cover various modifications, equivalent arrangements, and adaptations of the present application without departing from the spirit and scope of the present application.
