Description
Technical Field
The invention belongs to the field of medical instruments, and particularly relates to a tracheal cannula with an automatic cuff pressure monitoring device.
Background
Tracheal intubation refers to a method of placing a tracheal tube inside the trachea or bronchi through the glottis, through the oral or nasal cavity. The trachea cannula is mainly used in an ICU ward, can provide the best conditions for unobstructed respiratory tract, ventilation and oxygen supply, respiratory tract suction and the like, and is an important measure for rescuing patients with respiratory dysfunction. The lower end of the trachea cannula is provided with a cuff which is connected with an inflation inlet at the upper end of the trachea cannula through an inflation tube. It has the main functions as follows: (1) the position of the trachea cannula is fixed, the trachea cannula is ensured to be positioned in the center of a trachea, and the damage to the mucosa of the airway of a human body is prevented; (2) the trachea is kept closed, secretion and gastric content of the oropharynx part can be prevented from flowing back to enter the airway, and infection is effectively prevented.
It is therefore a necessary process to inflate the cuff through the inflation port so that the cuff reaches the proper size. Ensuring the proper size of the cuff requires ensuring the normal internal pressure of the cuff, and the phenomena of over-high pressure, over-low pressure, air leakage and the like can cause harm to patients. Too high intracapsular pressure for a long time causes the trachea to expand and the membrane portion of the posterior tracheal wall to be damaged. Too low an intracapsular pressure may cause the cuff to fail to close, and various secretions may flow into the trachea, causing asphyxia. And the occurrence of air leakage can cause local mucosa compression ischemia, and annular scar is caused after healing to cause tracheal stenosis.
The main methods and devices for cuff pressure monitoring currently available on the market are: (1) the evaluation method is judged by the pressure of the inflation inlet sensed by fingers or directly observing the size of the inflation inlet, and although the evaluation method is simple and convenient, the pressure cannot reach the expected value simply by personal experience due to no fixed reference standard. (2) The air bag pressure measuring meter method measures pressure by connecting the pressure measuring meter with the inflation inlet of the cuff to be measured, although the accuracy is high, the cuff pressure cannot be monitored in real time, the operation is complex, and the price of the meter is high. (3) Patent CN203943988U takes the trachea cannula of gasbag pressure indication buoy or gasbag pressure monitoring device, measures cuff pressure through the buoy of gasbag pressure indication, compares the result inadequately accurately with the mode that the sensor gathered pressure to can not the concrete data of visual display pressure. (4) Monitoring devices integration in the trachea cannula of inflation inlet, this trachea cannula because inflation inlet film and monitoring devices integration can destroy the structure of former trachea cannula inflation inlet, lead to unable utilization inflation inlet gasbag's sufficient degree to carry out preliminary aeration volume's determination, influence normal use.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
As shown in figure 1, the trachea cannula with the automatic cuff pressure monitoring device provided by the invention comprises an automatic cuff pressure monitoring device 1, an inflation inlet 2, an inflation tube 3, a cuff 4, a tube body 5, a machine connecting end 6 and a patient connecting end 7. The automatic cuff pressure monitoring device 1 is characterized in that after being filled with gas from the inflation inlet 2 by using an injector, the gas is sent into the automatic cuff pressure monitoring device 1 through the inflation tube 3, the structure is shown in figure 2, and the automatic cuff pressure monitoring device comprises a closed gas cavity 8, a pressure sensor 9, a sealing partition plate 10, a circuit 11, a display module 12, a power supply module 13 and an LED lamp alarm module 14. The pressure sensor 9 and the closed partition plate 10 form a sealing layer, and the whole device is divided into an upper layer and a lower layer. The upper layer is a closed air chamber 8 which is connected to the inflation tube 3 through which gas passes into the inflatable cuff 4 during inflation. The lower layer is a circuit installation cavity and comprises a circuit 11, a display module 12, a power supply module 13 and an LED lamp alarm module 14. One end of the tube body 5 is a machine connecting end 6 for connecting with a breathing machine or a breathing air bag, and the other end is a patient connecting end 7 fixed on the mucosa of a patient.
The closed air cavity 8 in the whole cuff pressure automatic monitoring device 1 is communicated and closed with the inflatable cuff 4, and the sealing layer consisting of the pressure sensor 9 and the closed clapboard 10 ensures that the pressure of the upper layer is equal to the pressure of the cuff 4.
The design of the automatic cuff pressure monitoring and displaying device 1 separated from the inflation inlet 2 ensures that the elastic film covered on the inflation inlet 2 can expand along with the pressure change of the inflation inlet 2 in the inflation process.
The working principle is as follows:
as shown in figure 1, the whole cuff pressure automatic monitoring device 1, the inflation inlet 2 and the inflation tube 3 are connected with the cuff 4. The pressure of the cuff 4 is the same as the pressure of the closed air cavity 8 and the inflation inlet 2 in the cuff pressure automatic monitoring device 1, the pressure of the cuff 4 is measured only by measuring the pressure in the closed air cavity 8 at the cuff pressure automatic monitoring device 1, and meanwhile, the pressure can be judged according to the collision degree of the elastic film of the inflation inlet 2.
The sealing layer consisting of the pressure sensor 9 and the closed clapboard 10 ensures that the pressure on the upper layer of the cuff pressure automatic monitoring device 1 is equal to the cuff pressure, and the pressure sensor acquires the pressure in the cuff 4 by acquiring the pressure in the closed air cavity 8.
And after the obtained pressure data is sent to the circuit 11 for processing, the display module 12 is controlled to display the pressure. The LED lamp in the LED lamp alarm module 14 can be controlled to give a prompt or alarm according to the pressure measured by the pressure sensor 9. Meanwhile, the power module 13 is strictly controlled in size and cost, and a power module consisting of a button battery and a voltage conversion circuit is selected to supply power to other modules.
The design enables medical personnel to judge the internal pressure of the cuff 4 according to the expansion degree of the elastic film at the inflating opening 2 and the experience of the estimation method, and can judge whether the cuff is full or not together with the display result in the cuff pressure automatic monitoring display device 1.
