Description

Tracheal cannula for critically ill patients

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a trachea cannula for severe patients.

Background

In the process of medical treatment, some serious patients have insufficient spontaneous breathing capacity, and the trachea cannula and breathing machine equipment are often required to be released to assist the patients in breathing. After the intubation is inserted into the trachea of a patient, the existing trachea intubation for the sputum secreted out of the trachea of the patient is generally provided with a suction tube for sucking out the sputum secreted out of the trachea of the patient. The suction tube is fitted in the side wall of the cannula body, and the suction port of the suction tube is generally arranged near the insertion end of the cannula, for example at the sepiolite site.

However, sputum is generally accumulated at the joint of the air bag and the cannula body, and a distance exists between the Murphy's hole and the air bag, so that the accumulated sputum is not easy to be sucked out.

Some cannulas arrange the Murphy's hole in the position that is close to the gasbag, but this will cause the inside that the outside sputum that deposits of intubate enters into the intubate through the Murphy's hole, causes the sputum to be inhaled by the patient along intubate inner wall easily.

The embodiment relates to a trachea cannula for a critically ill patient, which can improve the sputum suction effect of the trachea cannula and reduce the risk that the sputum in the trachea of the critically ill patient is sucked into the lung due to the configuration of the trachea cannula. This a trachea cannula for severe patients includes inside cavity and is formed with the intubate body of air flue, is close to the end, the ring of inserting of intubate body the gasbag that intubate body set up, with the gas tube of the inner chamber intercommunication of gasbag to and be used for the suction tube of suction patient trachea inner sputum. An annular lower liquid storage tank and an annular upper liquid storage tank are respectively constructed on the outer wall of the intubation tube body adjacent to the upper end and the lower end of the air bag; the straw part is embedded in the side wall of the cannula body, and suction inlets communicated with the straw are formed in the lower liquid storage tank and the upper liquid storage tank.

Based on the general structural principle, an exemplary structure of the endotracheal tube for critically ill patients of the present embodiment is shown in fig. 1, and mainly includes a tube body 1 which is hollow inside to form an airway, an air bag 4, an inflation tube 3 and a suction tube 2.

The air bag 4 is close to the insertion end 102 of the cannula body 1 and is arranged around the cannula body 1, the inflation tube 3 is communicated with the inner cavity of the air bag 4, and the suction tube 2 is used for sucking sputum in the trachea of a patient. The inflation tube 3 is used for inflating the inside of the air bag 4, preferably, the inflation tube 3 is partially embedded in the side wall of the cannula body 1, the inflation connector 301 of the inflation tube 3 is led out from the outer wall of the cannula body 1 at the side close to the leading-out end 101, and a pressure storage bag 303 is arranged on the leading-out section of the inflation tube 3 to improve the pressure maintaining effect of the air bag 4.

As shown in fig. 2, in order to achieve the object of the present invention, an annular lower reservoir 104 and an annular upper reservoir 105 are formed on the outer wall of the cannula body 1 adjacent to the upper and lower ends of the balloon 4, respectively; the suction pipe 2 is partially embedded in the side wall of the cannula body 1, and suction ports 202 communicated with the suction pipe 2 are formed in the lower reservoir 104 and the upper reservoir 105.

To enhance the pooling of the sputum in the lower reservoir 104, a plurality of introducer reservoirs 106 may also be configured on the outer wall of the cannula body 1 between the insertion end 102 and the balloon 4 in communication with the lower reservoir 104. The guiding grooves 106 may be integrally formed on the sidewall of the cannula body 1, and adopt a concave groove structure, preferably, the guiding grooves 106 are two grooves uniformly distributed at intervals around the axis of the cannula body 1, and each guiding groove 106 is arranged along the length direction of the cannula body 1. This facilitates the arrangement of the introduction groove 106 and facilitates the uniform and smooth introduction of the sputum.

As a conventional arrangement on the existing cannula, the sepia holes 103 are all arranged on the side wall of the cannula body 1 near the insertion end 102, and in the present embodiment, as shown in fig. 1 and fig. 2, the sepia holes 103 are arranged in cooperation with two introduction grooves 106. Specifically, the end face of the insertion end 102 is inclined with respect to the axis of the cannula body 1, a sepiolite hole 103 is formed in the sidewall of the cannula body 1 between the insertion end 102 and the balloon 4, the sepiolite hole 103 is formed between two guide grooves 106, and preferably, the sepiolite hole 103 is located in the middle between the two guide grooves 106 and on the sidewall facing away from the insertion end 102.

The guide hole 107 and the blocking ring 108 are arranged on the inner wall of the cannula body 1, so that sputum attached to the inner wall of the cannula body 1 can be guided out of the lower reservoir 104 along the guide hole 107 during expiration, and the sputum can be prevented from flowing to the lung along the inner wall due to shielding of the blocking ring 108 during inspiration.

The shape and angle of the stop ring 108 can be set in various ways, preferably, the connecting part of the stop ring 108 and the inner wall of the cannula body 1 is higher than the inner edge of the stop ring 108, and the upper and lower surfaces of the stop ring 108 are gradually thinner from the inner wall of the cannula body 1 to the inner edge of the stop ring 108, and are converged into a whole at the inner edge and decline towards the insertion end 102. The inner edge of the blocking ring 108 adopts a declination form, so that the effects of blocking airflow and guiding sputum can be improved.

In addition, in order to facilitate the sputum suction operation, as shown in fig. 1, the suction tube 2 is led out from the outer wall of the cannula body 1 near the leading end 101 of the cannula body 1 to form a suction tube connector 201, so as to facilitate the connection with the sputum suction device during the sputum suction operation.

According to the trachea cannula for the severe patients, the lower reservoir 104 and the upper reservoir 105 are formed on the outer wall of the cannula body 1 adjacent to the upper end and the lower end of the air bag 4, so that the sputum secreted by the trachea can be conveniently accumulated, the suction port 202 of the suction tube 2 is arranged in the lower reservoir 104 and the upper reservoir 105, the sputum can be sucked out periodically, the sputum suction effect of the cannula can be improved, and the risk that the sputum secreted by the trachea of the severe patients is sucked into the lung due to the arrangement of the cannula is reduced.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
