Description

Trachea cannula with respiration monitoring function

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a trachea cannula with breathe monitoring function.

Background

The trachea cannula is a technique that a special trachea catheter is placed into a trachea through a glottis and is called as trachea cannula, the technique can provide optimal conditions for unobstructed airways, ventilation and oxygen supply, respiratory tract suction, prevention of aspiration and the like, and the emergency trachea cannula technique becomes an important measure in the rescue process of cardiopulmonary resuscitation and critical patients accompanied with respiratory dysfunction. The trachea intubation is commonly used in the first-aid workThe important rescue technology is one of the most widely, effectively and quickly applied means in respiratory tract management, is the basic skill which must be mastered by medical staff, and plays a vital role in rescuing the life of a patient and reducing the fatality rate. CO 2₂The concentration is an important monitoring index for using the medical instrument, and the CO for judging the illness state of the patient is provided for doctors₂Content basis, clinically using special joint to connect with monitoring equipment, however, CO is now used when tracheal intubation is used₂The sampling monitoring location of the concentration is not the most direct part of the patient's exhaled breath and therefore there may be large deviations in the measured values from the actual values.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a trachea cannula with breathe monitor function is provided, can directly detect the CO of the gas of patient's exhalation when using₂Concentration, reducing the deviation between the measured value and the actual value.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a trachea cannula with breathe monitor function, is responsible for, cup joints the gasbag of being responsible for one end and sets up the connecting pipe of being responsible for the other end at the air guide including the air guide, the inside that the air guide was responsible for be provided with gas sampling pipe, this gas sampling pipe is responsible for from the air guide and installs the one end tip of gasbag and insert, is responsible for the opening on the lateral wall that is close to the connecting pipe from the air guide and wears out.

Preferably, one end of the gas sampling pipe penetrating out of the opening is connected with a luer connector, and the luer connector can be directly connected to CO₂And (4) concentration detection equipment.

Preferably, the air bag is connected with an air bag inflation tube, so that the air bag can be conveniently inflated.

In order not to influence the normal ventilation use of the air guide main pipe, the air sampling pipe is closely attached to the inner wall of the air guide main pipe.

In order to prevent air leakage, the opening is provided with a sealing piece for sealing a gap between the gas sampling pipe and the opening.

Has the advantages that: the utility model disclosesRelates to a trachea cannula with breathe monitor function, compares with prior art, and inside has increased gas sampling pipe, can lead directly to the tracheal depths of patient, makes trachea cannula can directly detect the CO of patient's expired gas when normal use₂The concentration reduces the deviation between the measured value and the actual value, the operation is simple, and the use of the tracheal cannula is not influenced.

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a front view half-section view of the utility model.

The figure is as follows: 1. an air guide main pipe; 2. an air bag inflation tube; 3. an air bag; 4. an opening; 5. a connecting pipe; 6. a luer fitting; 7. a gas sampling tube.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1-2, the utility model discloses an embodiment relates to a trachea cannula with respiration monitoring function, including the air guide person in charge 1, cup joint the gasbag 3 of the 1 one end of being responsible for in the air guide and set up the connecting pipe 5 of the 1 other end in the air guide person in charge, the air guide person in charge 1's inside be provided with gas sampling pipe 7, this gas sampling pipe 7 inserts from the one end tip that the air guide person in charge 1 installed gasbag 3, wears out from the opening 4 on the lateral wall that the air guide person in charge 1 is close to connecting pipe 5.

Referring to fig. 1 and 2, when in use, the gas sampling pipe 7 is firstly inserted into the main gas guide pipe 1, the main gas guide pipe 1 and the gas sampling pipe 7 are inserted into the airway of a patient together, one end of the gas sampling pipe 7 is exposed out of the mouth of the patient, and the connection of CO is convenient₂Concentration detection device, the patient breathes and can exhale CO simultaneously₂，CO₂Directly into the gas sampling tube 7 for the first time,direct access to CO₂In a concentration measuring apparatus, CO thus detected₂The concentration data are relatively close to the actual values.

In order to facilitate the connection of the gas sampling pipe 7, the end part of the gas sampling pipe 7, which penetrates out of the opening 4, is connected with a luer connector 6, and the luer connector 6 can be directly connected to CO₂And (4) concentration detection equipment.
