Example 1:

The invention provides an endotracheal tube integrated with a conical head.

In an embodiment of the invention, the tracheal cannula integrated with the conical head comprises a tube body 1, an air bag 2, an inflation assembly 3, a conical head 4 and a sputum suction assembly 5, wherein the conical head 4 is arranged in a hollow mode, the large end of the conical head 4 is connected with one end of the tube body 1 in a sealing mode, the small end of the conical head 4 extends towards the direction away from the axis of the conical head and is bent to form a suction part 6, an oxygen supply channel 7 communicated with the inner cavity of the tube body 1 is formed in the conical head 4, the sputum suction assembly 5 comprises an infusion tube 8 and a negative pressure source, the infusion tube 8 penetrates the tube body 1, one end of the infusion tube 8 extends to the suction part 6, and the other end of the infusion tube 8 penetrates the tube body 1 and is communicated with the negative pressure source.

The trachea cannula integrated with the conical head can plug the end part of the tube body 1 through the conical head 4, the oxygen supply channel 7 in the conical head 4 can still continuously supply oxygen in the plugging state of the tube body 1, and meanwhile, the infusion tube 8 in the tube body 1 can be matched with a negative pressure source to directly suck secretions such as sputum in the airway of a patient, so that synchronous operation of oxygen supply and sputum suction can be realized, namely, the connection of a breathing machine is not required to be disconnected when the patient sucks sputum, thereby not only remarkably reducing the hypoxia risk of the patient, but also improving the safety and convenience of clinical operation.

In particular, as shown in fig. 1 and 2, in the integrated cone head endotracheal tube of the present invention, the inflation assembly 3 may be a one-way valve as is common in the art, and is in communication with the balloon 2 via an air tube. From this can guarantee that gas pours into to gasbag 2 inside with the mode of unidirectional flow into to lock the pressure value after gasbag 2 inflation, thereby make the outer wall of gasbag 2 can closely laminate with patient's trachea inner wall, and then not only can effectively prevent that patient's air flue from leaking gas, mistake from inhaling the condition emergence, can also guarantee that the safe body 1 is stable to remain at the interior preset position of patient's trachea all the time in diagnosis and treat the in-process.

Furthermore, in the tracheal cannula integrated with the conical head, as the conical head 4 is arranged in a hollow way, one end of the infusion tube 8 in the sputum sucking assembly 5 extends to the suction part 6 of the conical head 4, and the other end of the infusion tube extends out of the tube body 1 and is communicated with a negative pressure source, so that suction can be generated through the negative pressure source and sputum and other secretion accumulated in the trachea of a patient can be sucked, the airway of the patient can be kept clean, blockage or infection can be avoided, meanwhile, the large end of the conical head 4 is connected with one end of the tube body 1 in a sealing way, so that the tube body 1 can be blocked, sputum can be effectively prevented from entering or remaining in the tube body 1 and flowing back to the trachea of the patient again, the cleaning effect on the sputum secretion can be guaranteed, and the tracheal cannula is reliable to use. It can be understood that, because the oxygen supply channel 7 communicated with the inner cavity of the tube body 1 is arranged on the conical head 4, the continuous ventilation of the airway of the patient can be maintained in the sputum suction process through the oxygen supply channel 7, so that the synchronous operation of oxygen supply and sputum suction operation is realized, namely, the connection of a breathing machine is not required to be disconnected and the sputum suction tube is plugged and pulled out when the patient sucks sputum, the operation steps are simplified, the safety risk of hypoxia and cardiopulmonary complications of the patient caused by oxygen supply interruption is effectively avoided, the safety and convenience of clinical operation are improved, the introduction of external pollution can be prevented, and the probability of secondary infection of the respiratory tract of the patient is reduced.

It is worth noting that, because the small end of the conical head 4 extends towards the direction far away from the axis of the conical head and bends to form the suction part 6, the suction part 6 which bends is beneficial to being attached to the inner wall of the trachea of a patient, so that secretion such as sputum can be conveniently sucked, the small end of the conical head 4 can be prevented from directly stabbing or scratching the inner wall of the trachea of the patient in the process of inserting the tube body 1 into the patient, the guiding effect is achieved on the insertion of the tube body 1, and the operation convenience and the intubation efficiency are improved. In addition, the cone head 4 can be made of rubber, silica gel and other materials, so that the softness of the cone head 4 is guaranteed, and meanwhile, the bending angle of the suction part 6 is preferably 135 degrees, and the length is 1cm, so that the cone head can be well adapted to the inner wall of a patient's trachea and good sputum suction effect is guaranteed.

In an embodiment, an oxygen inlet 9 is formed on the end face of the large end of the conical head 4, an oxygen outlet 10 is formed on the outer wall of the conical head 4, and the oxygen inlet 9 is communicated with the oxygen outlet 10 to form the oxygen supply channel 7. Specifically, as shown in fig. 1 and 2, the conical head 4 can plug the tube body 1 after being installed in place, at this time, the end face of the large end of the conical head 4 is provided with the oxygen inlet 9, so that oxygen still can smoothly enter the oxygen supply channel 7 and be discharged through the oxygen outlet 10 on the outer wall of the conical head 4 to realize continuous oxygen supply to a patient, and the oxygen supply channel 7 is physically isolated from the infusion tube 8 of the sputum suction assembly 5, thereby avoiding the influence of sputum suction operation on oxygen supply and preventing the sputum from flowing reversely to pollute an oxygen supply path, and further, the synchronous operation of oxygen supply and sputum suction to the patient can be satisfied, and the structure design is simple and reasonable.

In an embodiment, as shown in fig. 1 and 2, a baffle 11 for shielding the oxygen supply channel 7 is disposed at the oxygen outlet 10, and a notch 12 is formed at one end of the baffle 11 near the tube body 1. It can be understood that when the oxygen supply air flow passes through the oxygen outlet 10, the air flow pressure causes the baffle plate 11 to turn outwards, and at this time, a ventilation path can be formed through the notch 12 to ensure stable transportation of oxygen, and meanwhile, the turned-out baffle plate 11 can form a physical barrier to prevent sputum from entering the oxygen supply channel 7, so that not only can the stability of continuous oxygen supply be ensured, but also the blockage of the oxygen supply channel 7 caused by reverse flow of secretion such as sputum in an air channel can be prevented, and the clinical applicability and safety of the device can be further improved. It should be noted that, through opening notch 12 on baffle 11 near the one end of body 1, can raise notch 12 from this and the height of patient's trachea inner wall, and then reduce the probability that the sputum flows back to oxygen supply channel 7 through notch 12, structural design is simple, reasonable.

In one embodiment, the number of oxygen supply channels 7 is plural, and the plurality of oxygen supply channels 7 are arranged at intervals along the axis of the conical head 4. Specifically, as shown in fig. 1 and 2, a stable oxygen supply system can be formed by the parallel design of a plurality of oxygen supply channels 7, for example, when a part of the oxygen supply channel 7 is blocked due to the change of the body position of the conical head 4 or secretion accumulation, the rest of the oxygen supply channels 7 can still maintain sufficient ventilation to the patient, thereby remarkably improving the reliability and stability of oxygen supply. Further, the plurality of oxygen supply channels 7 are arranged at intervals along the axis of the conical head 4, so that the uniformity of oxygen transmission is ensured, the stimulation of airway mucosa of a patient due to strong local air flow is avoided, and the comfort and the safety of use are improved while the patient is ensured to continuously obtain sufficient oxygen supply.

In an embodiment, specifically, as shown in fig. 1 and fig. 2, the large end of the conical head 4 is tapered towards the direction away from the suction part 6, so that the conical head 4 is conveniently installed in the pipe body 1, the assembly difficulty is effectively reduced, the smoothness of the plug-in fit of the conical head 4 and the pipe body 1 is improved, and the operation is convenient.

In an embodiment, as shown in fig. 1 and 2, an annular flange 13 is formed on the outer wall of the conical head 4 close to the large end, and it can be understood that the accurate positioning of the conical head 4 in the pipe body 1 can be ensured through the annular flange 13, so that the conical head 4 is effectively prevented from loosening relative to the pipe body 1 in the use process, the connection tightness and stability of the conical head 4 and the pipe body 1 are improved, the air passage tightness is also enhanced, and the structure design is simple and reasonable.

In an embodiment, as shown in fig. 1 and 2, the sputum aspirator assembly 5 further includes a connector 14, the connector 14 is disposed at an end of the infusion tube 8 far away from the suction portion 6, the connector 14 is used for being detachably connected with a negative pressure source, a liquid draining hole communicated with the infusion tube 8 is formed in the connector 14, and the connector 14 is detachably mounted in the liquid draining hole. It will be appreciated that the connector 14 may be of a standardized interface design to ensure a secure connection with various types of negative pressure source equipment, avoiding the risk of falling out during operation. Furthermore, as the plug 15 is detachably arranged in the liquid discharge hole, the tracheal cannula with the integrated conical head has the advantages that in the use process, the plug 15 is removed and the external collecting device is connected with the liquid discharge hole, so that sputum can be directly discharged and collected, and the structural design is simple and reasonable.

In an embodiment, as shown in fig. 1 and 2, the port of the tube body 1 near the conical head 4 is in an outward expansion arrangement, at least one limiting groove 16 is uniformly and alternately formed on the inner wall of the tube body 1 along the circumferential direction, and lugs extending into the limiting groove 16 are formed on the infusion tube 8. Specifically, the port of the pipe body 1 close to the conical head 4 is formed to be in an outward expansion mode, so that the contact area between the inner wall of the pipe body 1 and the large end of the conical head 4 can be increased, and the connection stability of the pipe body 1 and the conical head 4 can be improved. Further, after the infusion tube 8 is installed in place, the lugs on the infusion tube 8 extend into the limit grooves 16 and are in plug-in fit with the limit grooves 16, so that circumferential limit of the infusion tube 8 can be achieved, and the infusion tube is simple and reasonable in structural design.

Meanwhile, as the conical head 4 adopts a flexible material (silica gel, rubber and the like) piece, one end of the infusion tube 8 extending into the conical head 4 only extends to the suction part 6 and does not extend into the suction part 6, thereby not only ensuring the structural strength of the conical head 4, but also ensuring the softness of the suction part 6 to effectively suck sputum, and being reliable in use. In addition, the infusion tube 8 stretches into one end of the conical head 4 and can be made into a 135-degree notch, so that the fitting effect of the port of the infusion tube 8 and the conical head 4 is improved, and the structural design is compact and reasonable.
