Description

Tracheal examination device and tracheal catheter

Technical Field

The present disclosure relates to the field of medical devices, and in particular to a tracheal inspection device; and also relates to an endotracheal tube.

Background

The bronchoscope is an optical fiber endoscope or an electronic endoscope capable of clearly inspecting the tissue under the trachea, is in an elongated and soft shape as a whole, can extend into the trachea or the bronchus and further ends, can image through a display screen, or can directly observe lesions of the trachea and the bronchus through an ocular lens. If necessary, some biopsy or interventional operations can be completed through the relevant instruments matched with the inserted bronchoscope. Because of the narrow airway, the entry and exit of the bronchoscope is difficult without establishing a passageway, and the airway and glottis may be damaged during the repeated entry and exit, resulting in glottic edema.

At present, when the bronchoscope is adopted for tracheal examination, a passage for repeatedly entering the air supply bronchoscope is not basically established, and the examination is inconvenient. In actual clinical practice, there are two ways of establishing airway passages: the first is to use a tracheal cannula hose to directly communicate with the invasive breathing machine so as to communicate with the airway; the second is to use a rigid tracheal passage, i.e. a cylindrical passage which is not flexible, and which needs to be placed in the case of general anesthesia, and which has high requirements for both the depth of anesthesia during surgery and the physical condition of the patient. Neither channel can be used for daily bronchoscopy.

In addition, airway hyperreactivity, i.e., cramping, occurs in some patients during the tracheal examination, which in turn leads to hypoxia. During the actual examination, if this happens, the operator needs to remove the bronchoscope and provide a simple ventilator to the patient to improve oxygenation, which makes the operation of the bronchoscope forced to be interrupted, which is very inconvenient. Moreover, during the examination, the patient may secrete excessive oropharyngeal secretions due to the stimulation of the bronchoscope, which may further cause a stimulating cough, and the operator also needs to interrupt the examination operation and suck the secretions.

The present disclosure provides a tracheal examination device, comprising a bronchoscope and a tracheal catheter, wherein the tracheal catheter comprises: intubation, an oxygen tube and a negative pressure suction tube. The cannula is similar to a clinically usual tracheal cannula, with a lumen, the opposite ends of which are designated as a first end and a second end for extending into the trachea, respectively. The bronchoscope is configured to penetrate from the lumen of the cannula to examine the condition of the respiratory system of the patient. The cannula can maintain the airway open after extending into the trachea, thereby providing an insertion path for the bronchoscope.

The present disclosure establishes a passageway for the repeated entry of an air supply tube scope into an examination by providing a cannula. The operator can take out the bronchoscope at any time in the inspection process to carry out local cleaning and change different mirrors, can also prevent to repeatedly advance the mirror and scratch the damage that causes to patient's glottis and trachea because of repeatedly. For the patient with a narrow airway, the bronchoscopy is difficult to directly carry out without establishing a channel, and the repeated entrance and exit of the bronchoscopy is more difficult; therefore, the cannula is inserted before the examination, and a channel is established, so that the patient with the airway stenosis can be examined smoothly.

The oxygen tube is configured to provide oxygen through the lumen of the cannula. While performing a tracheotomy, the tracheotomy device provided by the present disclosure can also directly provide oxygen to the patient. This prevents the patient from having airway cramps and thus hypoxia during the examination, and the operator no longer has to pause the examination during the examination due to the need to infuse oxygen to the patient, thus improving the efficiency of the bronchoscopy.

The negative pressure suction tube is positioned in the inner cavity, and an inlet of the negative pressure suction tube is arranged on the side wall of the cannula and is communicated with the outer side of the cannula. The negative pressure suction tube is a pipeline for sucking secretion, and in the process of performing bronchoscopy, patients can generate excessive oral secretion and throat secretion under stimulation, and operators need to use the negative pressure suction tube to suck secretion so as to prevent the patients from cough due to excessive secretion and influence the performance of the examination. This disclosure sets up negative pressure suction tube in the inner chamber of intubate, and directly opens on the intubate lateral wall, just so can attract secretion at any time in the inspection process, no longer need the operator to pause the inspection operation to the efficiency of bronchoscopy has been improved.

The oxygen pipe and the negative pressure suction pipe are thin soft pipelines with the inner diameters far smaller than the inner diameter of the cannula, and the two thin pipes are positioned in the inner cavity of the cannula. The inner cavity is provided with an oxygen pipe and a negative pressure suction pipe, and is also provided with enough space for the free entrance and exit of the air supply tube lens.

The utility model discloses a through setting up the intubate, established the passageway that the air supply tube mirror got into the inspection repeatedly, can also be at the in-process that carries out the trachea inspection directly for patient's oxygen suppliment, directly inhale the oropharynx secretion of patient, just so promoted patient's comfort level when carrying out the trachea inspection, still make the inspection operation of art person more convenient. The operator no longer needs to interrupt the examination due to hypoxia or excessive oropharynx secretion of the patient, and by adopting the tracheal examination device provided by the disclosure, the oropharynx secretion can be sucked at any time and always supplied with oxygen in the whole examination process, so that the examination efficiency is higher.

Specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present disclosure provides a tracheal inspection device comprising: a cannula 1, a bronchoscope 2, an oxygen tube 3 and a negative pressure suction tube 4. The cannula 1 is similar to a clinically usual endotracheal tube, the cannula 1 having a lumen, the opposite ends of which are designated as a first end 11 and a second end 12 for extending into the trachea, respectively. The bronchoscope 2 is configured to penetrate from the lumen of the cannula 1 to examine the condition of the patient's respiratory system. The cannula 1 is capable of maintaining the airway open after extending into the trachea, thereby providing an insertion path for the bronchoscope 2.

By providing the cannula 1, the present disclosure establishes a passageway for the gas supply tube mirror 2 to repeatedly enter the examination. The operator can take out the bronchoscope 2 at any time in the inspection process to carry out local cleaning and change different mirrors, can also prevent to repeatedly advance the mirror and scratch the damage that causes to patient's glottis and trachea because of repeatedly. For the patient with a narrow airway, the bronchoscopy is difficult to directly carry out without establishing a channel, and the repeated entrance and exit of the bronchoscopy is more difficult; therefore, the intubation tube 1 can be sleeved on the bronchoscope 2 during examination, and after the bronchoscope 2 is inserted into the airway, the intubation tube 1 is inserted into the airway along the guide of the bronchoscope 2 and fixed, so that a channel is established, and a patient with a narrow airway can be examined smoothly.

In one embodiment of the present disclosure, as shown in fig. 1 and 2, the second end 12 of the cannula 1 is configured as a bevel. The second end 12 of the cannula 1 is provided with a bevel in order to reduce the resistance to insertion, as the cannula 1 is inserted into the trachea, which often makes it difficult for the patient to relax the airway. This allows the cannula 1 to be inserted more easily into the airway and more easily through the glottis. In addition, the beveled tip of the second end 12 is configured in a gentle arc to prevent scratching of the patient's airway during insertion.

The oxygen tube 3 is configured to provide oxygen through the lumen of the cannula 1. While performing a tracheotomy, the tracheotomy device provided by the present disclosure can also directly provide oxygen to the patient. This prevents the patient from having airway cramps and thus hypoxia during the examination, and the operator no longer has to pause the examination during the examination due to the need to infuse oxygen to the patient, thus improving the efficiency of the bronchoscopy.

In one embodiment of the present disclosure, with continued reference to fig. 1 and 2, one end of oxygen tube 3 is configured to pass out of the lumen of cannula 1 and for connection with oxygen supply 31. The oxygen supply device 31 may be a medical oxygen generator, a respirator, a medical center oxygen supply apparatus, or the like, which is not limited by the present disclosure. The oxygen tube 3 is an elongated flexible tube, and one end of the flexible tube penetrating out of the inner cavity of the cannula 1 is connected with the oxygen supply device 31, so that oxygen directly enters the oxygen tube 3 from the oxygen supply device 31. The other end of the oxygen pipe 3 is positioned in the inner cavity of the cannula 1, and oxygen in the oxygen pipe 3 is directly conveyed into a patient through the cannula 1, so that oxygenation of the patient is effectively improved, and hypoxia is prevented.

The oxygen supply device 31 can be manually opened by an operator at any time in the examination process, and when the patient needs to inhale oxygen, particularly when airway hyperreaction occurs, the operator does not need to take out the bronchoscope 2, and can enable oxygen to be introduced into the oxygen tube 3 only by opening the oxygen supply device 31, so as to supply oxygen for the patient. The oxygen supply device 31 can be kept open in the whole examination process, so that oxygen is supplied to the patient in the whole examination process, and the condition of hypoxia of the patient is prevented. It should be noted that, when an operation (such as an argon knife operation or a laser treatment operation) requiring oxygen isolation is performed under a bronchoscope, the oxygen supply device 31 may not be turned on, so that oxidation, carbonization, smoke and odor of tissues are reduced.

In one embodiment of the present disclosure, referring to fig. 1, an oxygen tube 3 is configured to be integrally formed at the inner wall location of a cannula 1. As shown in fig. 1, the portion of the oxygen tube 3 located in the inner cavity of the cannula 1 is integrally formed with the cannula 1, that is, the outer wall of the oxygen tube 3 is a part of the outer wall of the cannula 1. On the outer wall of the cannula 1 near the first end 11, the oxygen tube 3 extends out to connect with the oxygen supply 31. The design of integrated into one piece makes oxygen pipe 3 can be fixed in the inner chamber of intubate 1, and at the in-process that bronchoscope 2 business turn over intubate 1 inner chamber, oxygen pipe 3 can not cause any interference to bronchoscope 2.

Furthermore, the insertion end of the oxygen tube 3 may be configured to be flush with the second end 12 of the cannula 1. The oxygen tube 3 does not have to extend beyond the second end 12 of the cannula 1, since during the examination the second end 12 has been inserted beyond the glottis, where the oxygen tube 3 delivers oxygen directly, which is fully satisfactory for oxygen supply. If the insertion end of the oxygen tube 3 is arranged to pass out of the second end 12 of the cannula 1, the oxygen tube 3 may interfere with the examination of the bronchoscope 2.

The negative pressure suction tube 4 is located in the lumen of the cannula 1, and an inlet 42 of the negative pressure suction tube 4 is opened at a side wall of the cannula 1 and is configured to communicate with an outside of the cannula 1. The negative pressure suction tube 4 is a pipe for sucking the secretion 5, and in the process of performing bronchoscopy, the patient can generate excessive oral secretion 5 and throat secretion 5 under stimulation, so that the operator needs to suck the secretion 5 by using the negative pressure suction tube 4 to prevent the patient from cough caused by excessive secretion 5 and influence the performance of the examination. The negative pressure suction tube 4 is arranged in the inner cavity of the cannula 1, and the inlet 42 is directly formed in the side wall of the cannula 1, so that secretion 5 can be sucked out at any time in the inspection process, and the operator is not required to pause the inspection operation, so that the efficiency of bronchoscopy is improved.

In one embodiment of the present disclosure, with continued reference to fig. 1 and 2, one end of the negative pressure suction tube 4 is configured to pass out of the lumen of the cannula 1 and for connection with a negative pressure suction device 41. The negative pressure suction device 41 may be an operating room negative pressure suction device, a medical negative pressure suction pump, a hospital center negative pressure suction system, or the like, which is not limited by the present disclosure. The negative pressure suction tube 4 is an elongated flexible tube, one end of the tube penetrating out of the inner cavity of the cannula 1 is connected with the negative pressure suction device 41, the other end is positioned in the inner cavity of the cannula 1, and an inlet 42 is arranged on the side wall of the cannula 1.

The negative pressure suction device 41 can be kept open in the whole examination process, and when the secretion of the oropharynx of the patient is excessive and extends to the inlet 42, the secretion can be directly sucked into the negative pressure suction tube 4, so that the secretion of the oropharynx of the patient is cleared, and the patient is prevented from choking due to the excessive secretion. The negative pressure suction device 41 can also be manually opened by a user at any time in the examination process, when the oropharynx secretion 5 of the patient is too much, the user does not need to take out the bronchoscope 2, and can directly suck the secretion 5 into the negative pressure suction tube 4 by only opening the negative pressure suction device 41, so that the oropharynx secretion 5 of the patient is removed; after the removal, the operator can turn off the negative pressure suction device 41 and continue the examination.

In one embodiment of the present disclosure, referring to fig. 1, the negative pressure suction tube 4 is configured to be integrally formed at the inner wall position of the cannula 1. As shown in fig. 1, the portion of the negative pressure suction tube 4 located in the inner cavity of the cannula 1 is integrally formed with the cannula 1, that is, the outer wall of the negative pressure suction tube 4 is a part of the outer wall of the cannula 1. On the outer wall of the cannula 1 near the first end 11, the negative pressure suction tube 4 extends out to connect with the negative pressure suction device 41. The integrated into one piece's design makes negative pressure suction tube 4 can be fixed in the inner chamber of intubate 1, and in the in-process that bronchoscope 2 business turn over intubate 1 inner chamber, negative pressure suction tube 4 can not cause any interference to bronchoscope 2.

The oxygen tube 3 and the negative pressure suction tube 4 are thin and soft pipelines with the diameter far smaller than the inner diameter of the cannula 1, and the two thin pipelines are positioned in the inner cavity of the cannula 1. As shown in fig. 1, the inner cavity is provided with enough space for the air supply tube mirror 2 to freely enter and exit after the oxygen tube 3 and the negative pressure suction tube 4 are accommodated. The inner diameter of the cannula 1 and the inner diameters of the oxygen pipe 3 and the negative pressure suction pipe 4 are all of various types, so that the device is suitable for different crowds, and suitable for adults, children and infants.

This disclosure has established through setting up intubate 1 that air supply pipe mirror 2 gets into the passageway of inspection repeatedly, can also be at the in-process that carries out the tracheal inspection directly for patient's oxygen suppliment, directly inhales the oropharynx secretion 5 of patient, has just so promoted patient's comfort level when carrying out the tracheal inspection, still makes the inspection operation of art person more convenient. The operator no longer needs to interrupt the examination due to hypoxia or excessive oropharynx secretion 5 of the patient, and by adopting the tracheal examination device provided by the disclosure, the oropharynx secretion 5 can be always supplied with oxygen and sucked at any time in the whole examination process, so that the examination efficiency is higher.

In one embodiment of the present disclosure, the cannula 1 is about 16-18cm in length. The trachea cannula commonly used in clinic has various models, and an operator can select according to the actual situation of a patient. Taking adults as an example, the total length of the trachea of an adult is about 11-13cm, and the trachea cannula usually needs to go deep for 4-6cm after being inserted into the trachea and passing through the glottis; accordingly, the length of the tracheal cannula used by the adult female is about 20-22cm, and the length of the tracheal cannula used by the adult male is about 22-24cm. The length of the cannula 1 in the present disclosure is shorter than the clinically usual endotracheal tube, and the length of the cannula 1 for use by adults is about 16-18cm. The cannula 1 used in the present disclosure is somewhat shorter than the commonly used tracheal cannula in clinic, because the end of the tracheal cannula not inserted into the trachea often needs to be connected to a ventilator, and therefore a certain length needs to be set aside for connection. The cannula 1 of the present utility model is configured to provide a passageway for insertion of the bronchoscope 2, and thus need not be left for this length, but need only be capable of being secured in the patient's mouth.

In one embodiment of the present disclosure, the first end 11 of the cannula 1 is configured to be connected with a mouthpiece. After insertion of the cannula 1 into the airway of a patient, the operator needs to secure the first end 11 of the cannula 1 to the mouthpiece. The mouth gag can prevent the patient from biting the tracheal examination device in the mouth, can also keep the mouth open, and is convenient for the operator to carry out examination work.

The insertion end of the tracheal cannula commonly used in clinic at present is often provided with an inflatable air bag, and an operator can inflate the air bag after the cannula is completed, so that the tracheal cannula and the trachea are fixed together. However, if too much inflation causes the loss of the trachea, too little inflation causes the instability of fixation, and the setting of the air bag can make the airway of the patient full of foreign matters in the whole examination course, thereby aggravating the uncomfortable feeling of the patient. The mode that this disclosure adopted the oral area to fix can effectively improve patient's comfort level.

In one embodiment of the present disclosure, the inlet 42 of the negative pressure suction tube 4 is 100mm to 110mm from the first end 11 of the cannula 1. Since the overall length of the cannula 1 is about 16-18cm, the inlet 42 of the negative pressure suction tube 4 is located just near the glottis when the cannula 1 is inserted into the patient's airway. In the clinical examination, the patient performs bronchoscopy in a prone position, and in the case of an endotracheal tube, the patient cannot perform swallowing, and thus secretions 5 generated in the mouth and pharynx accumulate at a position near the glottis. Therefore, the inlet 42 of the negative pressure suction tube 4 is arranged at a position near the glottis, which can facilitate the negative pressure suction tube 4 to suck excessive oropharyngeal secretions 5 at any time.

The position of the inlet 42 of the negative pressure suction tube 4 may be changed according to the length of the cannula 1. The length of the cannula 1 is about 16-18cm when it is at a distance of 100mm to 110mm from the first end 11 of the cannula 1, i.e. a size suitable for an adult. When producing an endotracheal tube suitable for use with a child or infant, it is desirable to adaptively change the position of the inlet port 42 of the negative pressure suction tube 4 so that it is positioned at the glottis of the child or infant so that the negative pressure suction tube 4 will suck excess oropharyngeal secretions 5 at any time.

In one embodiment of the present disclosure, the cannula 1 is made of a medical PVC material or a silicone material. The trachea cannula commonly used in clinic is made of three materials, namely medical PVC material, silica gel material and metal material. Among them, the tracheal cannula made of a metal material is a hard cannula, and the cannula 1 in the present disclosure is a soft cannula, so that the cannula 1 cannot be produced from a metal material. The soft cannula 1 can be made of both medical PVC material and silica gel material, and the material of the cannula 1 is not particularly limited in the present disclosure, so long as the medical standard is met and the cannula 1 can be made of soft enough material.

In addition, the oxygen pipe 3 and the negative pressure suction pipe 4 which are integrally formed with the cannula 1 can also be made of medical PVC materials or silica gel materials. Preferably, the oxygen pipe 3 and the negative pressure suction pipe 4 are made of materials consistent with the intubation 1, so that the production cost is reduced, and the structure of integrated forming is convenient to construct.

The present disclosure also provides an endotracheal tube, as shown in fig. 2, comprising: a cannula 1, an oxygen tube 3 and a negative pressure suction tube 4. The cannula 1 has a lumen, the opposite ends of the cannula 1 being denoted as a first end 11 and a second end 12 for extending into the trachea, respectively; the oxygen tube 3 is configured to provide oxygen through the lumen of the cannula 1; the negative pressure suction tube 4 is located in the lumen, and an inlet 42 of the negative pressure suction tube 4 is opened at a side wall of the cannula 1 and is configured to communicate with an outside of the cannula 1.

The endotracheal tube can be used during tracheal examination, and the cannula 1 provides support for the airway, allowing the examination apparatus to be freely accessed within the lumen of the cannula 1. The examination device may be a bronchoscope 2, but may also be other types of tracheal examination devices, such as biopsy devices, without limitation of the present disclosure.

The specific structures and connection modes of the intubation tube 1, the oxygen tube 3, the negative pressure suction tube 4 and the three in the tracheal catheter provided by the disclosure are identical to those described in the foregoing, and are not repeated here.

The foregoing description of the embodiments of the present disclosure has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or the technical improvements in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
