After long-term use of the tracheotomy tube, foreign matters such as sputum scab, airway secretion, blood or airway mucosa castoff and the like can adhere to the inner wall of the tube. When this occurs, the healthcare worker typically uses sputum aspiration or irrigation by injecting saline into the tracheostomy tube orifice.
Sputum aspiration typically removes some of the freshly adhered sputum scab, airway secretions, blood or airway mucosal casts. However, if the medical staff does not suck out the foreign matters in time, the foreign matters are left on the inner wall of the tracheotomy sleeve for too long, and the foreign matters can be closely adhered to the inner wall of the sleeve. The medical staff is difficult to suck out the foreign matters in a sputum sucking mode. If the adhered foreign matters cannot be removed in time, the volume of the foreign matters can be continuously increased along with the increase of the service time, the situation that the lumen is partially or completely blocked finally occurs, the ventilation of a patient can be partially blocked, even suffocation occurs, and the life of the patient is endangered when serious.
To solve the above problems, medical staff generally adopts a flushing method of injecting physiological saline at the orifice of a tracheostomy tube. However, this flushing method has drawbacks: when the physiological saline is injected into the tracheotomy tube, the physiological saline only flows down along a certain inner side wall of the tracheotomy tube, can not moisten secretion adhered to different positions of the inner wall of the tracheotomy tube, and can not wash foreign matters in multiple directions. If all secretions adhered to different positions of the inner wall of the tracheotomy tube need to be softened, physiological saline needs to be injected into different positions of the tracheotomy tube for multiple times, and the operation is complex.

As shown in fig. 1 to 3, a tracheostomy tube according to a preferred embodiment of the present invention includes a tube body 1, wherein the tube body 1 is respectively penetrated with a flushing tube 3 and a breathing tube 2 along an axial direction, the flushing tube 3 is positioned at one side of the breathing tube 2, the flushing tube 3 is radially provided with a transfer tube 4, one end of the transfer tube 4 is communicated with the flushing tube 3, the transfer tube 4 at least partially surrounds the outer side of the breathing tube 2, and the inner side of the transfer tube 4 is communicated with the breathing tube 2.
Based on the above technical scheme, the respiratory catheter 2 has the same pipeline function as the existing tracheotomy tube, and is used for the expiration and inspiration of a patient, and foreign matters such as sputum are easy to adhere to the inner wall of the respiratory catheter 2. The tracheotomy tube provided by the invention is provided with the flushing tube 3 on the conventional tracheotomy tube for medical staff to inject physiological saline. The flushing tube 3 communicates with the breathing conduit 2 via a transfer tube 4. Because the transfer tube 4 at least partially and even completely surrounds the periphery of the breathing tube 2, physiological saline can flow down from different positions of the flushing tube 3, can flow into the breathing tube 2 from multiple directions, and softens secretions adhered to different positions of the inner wall of the breathing tube. In use, a healthcare worker inserts a sputum aspirator tube in communication with the negative pressure device into the respiratory catheter 2. Another medical staff injects physiological saline from the orifice of the flushing pipe 3, and the physiological saline can flow into the breathing conduit 2 through the transmission pipe 4 under the influence of self gravity and flow out along the inner wall of the breathing conduit 2 under the influence of the position and angle of the cutting sleeve of the gas pipe inserted into a human body, so as to flush and soften foreign matters. When normal saline and softened foreign matters flow to the bottom of the breathing catheter 2, medical staff immediately suck the normal saline and the foreign matters out by using the sputum suction tube, so that the effect of removing the foreign matters is achieved, the operation is simple, the normal saline does not need to be repeatedly injected, and the labor intensity of the medical staff is reduced. The tracheotomy tube has a simple structure, and can meet the use requirements of patients with excessive airway secretions, airway bleeding or airway mucosa falling off and insufficient airway humidification conditions.
The cross-sectional shape of the breathing conduit 2 is the same as that of the prior tracheostomy tube, and is round. Preferably, the length of the transfer tube 4 surrounding the breathing tube 2 is defined as a, the outer circumference of the breathing tube 2 is defined as b, a being in the range of a.gtoreq.0.5 b. That is, the length of the transfer tube 4 is more than half of the outer circumference of the breathing conduit 2, and the cross-sectional shape of the transfer tube 2 should be a semicircle or a circular arc or a circle with an arc of more than 180 °. When a is more than or equal to 0.5b, the physiological saline can be guaranteed to wash most foreign matters adhered to the inner wall of the breathing catheter 2. In the production of such tracheostomy tubes, the surrounding position and surrounding ratio of the delivery tube 4 may be adjusted according to the actual needs. In this embodiment, the shape of the transfer tube 4 is annular, and the transfer tube 4 entirely surrounds the outer side of the breathing tube 2, which is beneficial to multi-directional flushing of the breathing tube.
In addition, the flushing pipe 3 is a circular pipe. In this embodiment, the upper end of the flushing pipe 3 extends out of the sleeve body 1, the inner diameter of the part of the flushing pipe 3 extending out of the sleeve body 1 is 0.8 mm-1.0 mm, and the outer diameter is 1.3 mm-1.5 mm. The inner diameter of the portion of the flushing pipe 3 located inside the sleeve body 1 is 0.4 mm-0.5 mm.
Specifically, the delivery tube 4 communicates with the breathing conduit 2 through a flow orifice 5. The water flow hole 5 is positioned at the inner side of the transmission pipe 4, and the water flow hole 5 is positioned at the outer side of the breathing conduit 2, so that the communication between the transmission pipe 4 and the breathing conduit 2 can be realized. After the normal saline is injected into the orifice of the flushing pipe 3, the normal saline flows into the inner wall of the breathing conduit 2 along the flushing pipe 3 through the water flow hole 5 so as to flush and soften the foreign matters. The number of the water holes 5 is more than two, and the water holes 5 are uniformly distributed on the transmission pipe 4 and the breathing conduit 2, so that physiological saline can be conveniently flushed out along the sides of the inner wall of the breathing conduit 2, and the effect of uniformly flushing foreign matters on the sides of the breathing conduit 2 is achieved. In this embodiment, the number of the water holes 5 is three, and the water holes 5 are uniformly distributed at equal intervals along the circumferential direction of the breathing conduit 2, that is, the water holes 5 are distributed at intervals of 120 ° with the center of the breathing conduit 2 as the center, so that the inner wall of the breathing conduit 2 can be flushed from different angles, and the probability of cleaning foreign matters at different positions is increased. The water flow holes 5 are all circular in shape. The aperture of the water flow hole 5 is defined as c, and the range of c is more than or equal to 0.4mm and less than or equal to 0.5mm. The aperture of the water flow hole 5 is smaller, and when water is injected into the flushing pipe 3, water with larger pressure is flushed out of the water flow hole 5, so that foreign matters such as sputum scab and blood scab adhered to the inner wall of the breathing conduit 2 can be effectively loosened. When the existing tracheotomy tube is used, normal saline is injected into the tracheotomy tube, and because the normal saline directly flows in from the upper end of the tracheotomy tube and flows out from the lower end of the tracheotomy tube, the flowing path is short, and the normal saline quickly flows into the deep lung of a patient, so that the patient is easy to choking and cough, severe cough, rapid decrease of blood oxygen saturation, rising of blood pressure and other complications occur. The tracheotomy tube provided by the invention firstly utilizes the pipelines such as the flushing pipe 3, the transmission pipe 4 and the like to prolong the path of physiological saline, and then the running time of water flow is prolonged by arranging the water flow hole 5 with smaller aperture, so that more operation time is provided for the actions of medical staff to suck out foreign matters and physiological saline by using the sputum suction pipe, the unexpected occurrence of untimely sputum suction is avoided, and the risk of physiological saline flowing into deep lung is reduced.
Wherein, in order to achieve better cleaning effect, the number of the transfer pipes 4 is more than two, and each transfer pipe 4 is arranged up and down along the axial direction of the breathing conduit 2. In the present embodiment, the number of transfer tubes 4 is three or four. After the normal saline flows in from the flushing pipe 3, a part of the normal saline flows into the first transfer pipe 4, flows out from the water flow hole 5 of the first transfer pipe 4, and another part of the normal saline continues to flow in the flushing pipe 3 until flowing into the next transfer pipe 4. The plurality of transfer pipes 4 are arranged to be beneficial to flushing the inner wall of the breathing conduit from multi-angle multi-azimuth large impact force.
Further, the length of the sleeve body 1 and the length of the breathing conduit 2 are longer than the length of the flushing pipe 3, so that flushing fluid can be effectively sucked out by the sputum suction pipe. One end of the injection of physiological saline is defined as a first end of the cannula body 1, and the other end is defined as a second end. One end port of the breathing conduit 2 is flush with the first end face, and the other end port of the breathing conduit 2 is flush with the second end face, so that raw materials for manufacturing the tracheotomy tube are saved as much as possible. The sputum suction tube is inserted to 1 cm-1.5 cm above the second end part of the sleeve body, so that sputum can be sucked more effectively, and the tracheal mucosa is prevented from being damaged.
In addition, the tracheostomy tube further comprises fixing wings 6, and the fixing wings 6 are fixedly connected to the outer side of the tube body 1. The outside of sleeve body is equipped with gasbag 7 and trachea 8, and gasbag 7 passes through trachea 8 and is connected with external aerating device. The air pipe 8 is connected to the outside of the sleeve body 1, one end of the air pipe extends out of the upper part of the fixed wing 6, and the other end is communicated with the air bag 7. When in use, the air bag 7 is inflated through the air pipe 8, and the air bag 7 is inflated to be abutted in the air pipe of a human body, so that the position of the tracheotomy sleeve is fixed.
More preferably, the end face of the sleeve body 1, which is close to the air bag 7, is an inclined plane, and the inclined angle of the end face of the sleeve body 1 is 120-145 degrees. Since the end face of the breathing conduit 2 is flush with the end face of the sleeve body 1, the end face of the breathing conduit 2 near the balloon 7 is also a bevel. If the end face of the respiratory catheter 2 is designed as a straight section, foreign matters such as sputum scab, blood scab or fallen airway mucosa are easily accumulated on the orifice, so that blockage or flap formation is caused, and ventilation is affected. The end face of the breathing conduit 2 is designed to be an inclined plane, so that the area of a pipe orifice can be increased, and the probability that secretion or sputum scab or blood scab is blocked at the pipe orifice of the breathing conduit 2 is reduced; and when the sputum suction tube sucks sputum in the vertical direction under negative pressure, a shearing force is formed on the foreign matters, so that the foreign matters are deformed and are easier to suck into the sputum suction tube.
The working process of the invention is as follows: the balloon 7 is inflated to fix the position of the cannula body 1 in the human body. When sputum aspiration is needed, two medical staff work cooperatively. One medical staff connects the sputum suction tube with the negative pressure device, inserts the sputum suction tube into the breathing catheter 2 and stretches to the position 1 cm-1.5 cm above the tail end of the breathing catheter 2 so as to avoid the negative pressure from damaging airway mucosa. Another medical staff injects physiological saline into the mouth of the flushing pipe 3. Part of the physiological saline flows from the water flowing hole 5 to the inner wall of the breathing conduit 2 through the transmission pipe 4, washes and softens the foreign matters attached to the inner wall of the breathing conduit 2, and drives the foreign matters to flow down along the inner wall of the breathing conduit 2 along with the physiological saline. Another portion of the physiological saline continues along the flushing pipe 3 into another transfer pipe 4 located below the transfer pipe 4, from the water flow hole 5 of the other transfer pipe 4 to the inner wall of the breathing conduit 2. The medical staff can suck out the physiological saline and the foreign matters in time by using the sputum aspirator tube. The tracheotomy cannula provided by the invention can be used by medical staff to flush foreign matters in multiple directions under high pressure, and is convenient to operate.
In summary, embodiments of the present invention provide a tracheostomy tube that adds an irrigation tube that communicates with a respiratory catheter through a delivery tube. When in use, the sputum suction tube is extended into the respiratory catheter, and a small amount of physiological saline is injected into the flushing tube. Because the transfer pipe at least partially surrounds the outside at the breathing catheter and is communicated with the breathing catheter, physiological saline in the flushing pipe can flow down from different positions at the inner side of the transfer pipe, physiological saline can flow through a plurality of positions at the inner wall of the tracheotomy sleeve, and secretion adhered to a plurality of positions at the inner wall of the breathing catheter can be flushed by the physiological saline, so that the foreign matters can be cleaned in multiple directions and multiple angles. The washed liquid and the foreign matters such as sloughed secretion, sputum scab, blood scab, airway mucosa slough and the like can be timely sucked out through the sputum suction tube. The tracheotomy sleeve is simple in structure and convenient to use, physiological saline is not required to be repeatedly injected into the flushing pipe for many times, labor intensity of nursing staff is reduced, flushing effect is good, and airway nursing quality is effectively improved. The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
