Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical treatment, in particular to a multifunctional tracheal catheter, a processing device and a preparation method. BACKGROUND

[0002] The tracheal catheter is a necessary device for clinical respiratory support treatment and establishment of artificial airway, and is usually used for patients with general anesthesia and respiratory dysfunction. Although the tracheal catheter is a necessary device for respiratory support, as an artificial airway, in actual use, due to its being a kind of extracorporeal implant, when fixed in the trachea, it may cause excessive stress reaction due to tissue contact stimulation. Such stress reaction is very unfavorable for the patient receiving treatment, especially for patients with pre-existing cardiovascular and nervous system diseases, and severe accidents such as cardiovascular and cerebrovascular accidents may occur due to such excessive stress reaction.

[0003] During the use of the tracheal catheter, the user hopes to be able to observe the actual position of the catheter throughout the process, observe the relative relationship between the catheter and the surrounding tissue structure, so as to avoid ventilation problems caused by abnormal catheter position, and also hopes to be able to observe the position of other tube treatment devices such as sputum suction tube and bronchial occlusion tube in the trachea in real time when placing them, so as to achieve the purpose of precise treatment.

[0004] However, the bronchial occlusion tube currently used in clinical practice is generally used in conjunction with a single-lumen tracheal catheter, and needs to be placed into the left or right bronchus under the observation of a bronchoscope. During the placement process, the bronchoscope and the occlusion tube share the tracheal catheter lumen, and interfere with each other, so it is necessary to repeatedly adjust the head end direction of the occlusion tube to enter the target bronchus, which is very inconvenient to operate.

[0005] Furthermore, in order to avoid excessive stress reaction of the patient when the tracheal catheter is fixed in the trachea during the establishment of artificial airway, intravenous systemic use of anesthetics, sedatives and muscle relaxants is currently generally adopted. These drugs have obvious inhibitory effect on the functions of respiratory, circulatory and motor systems. The premise of awakening and extubation of the anesthetized patient is that these drugs are metabolized and eliminated by the body. After the inhibitory effect of the drugs on the respiratory, circulatory and motor systems of the body is eliminated, tracheal extubation can be safely completed.

[0006] Generally speaking, tracheal intubation reaction is an unavoidable process. The use of local anesthetics on the tracheal mucosa is an effective method to eliminate tracheal intubation reaction. However, there is currently no similar device that can continuously, on demand and at any time, perform tracheal mucosa anesthesia. In the prior art, methods such as puncture through the cricothyroid membrane to inject local anesthetics or use a spray tube to spray local anesthetics through the glottis are usually adopted. The problem with such methods is that they cause damage and are difficult to operate, and the local anesthetic effect disappears as the intubation time prolongs, and the drug cannot be used again.

[0007] Therefore, there is an urgent need for a tracheal tube that can allow an operator to conveniently observe the actual position of the tracheal tube during the establishment of an artificial airway, understand the relative positional relationship between the tracheal tube and the surrounding tissue structure, and facilitate drug administration to the trachea and / or bronchus.

[0093] As shown in Figures 1 to 6 , the multifunctional tracheal tube comprises a main tube 1, a miniature camera 2, a first spray pipe 3 and a second spray pipe 4;

[0094] The main tube 1 is provided with a signal transmission line containing cavity 21 extending from the upper half of the main tube 1 to the outlet 11 at the bottom of the main tube 1, and the miniature camera 2 is arranged at the bottom end of the signal transmission line containing cavity 21;

[0095] The first spray pipe 3 and the second spray pipe 4 both extend from the upper half of the main tube 1 to the lower half of the main tube 1.

[0096] The multifunctional tracheal tube with such a structure can be observed by the operator by means of the miniature camera 2, and can observe and guide some treatment devices such as bronchoscope and occlusion tube placed through the tracheal tube, so as to facilitate the operator to operate more conveniently and accurately; at the same time, by means of the first spray pipe 3 and the second spray pipe 4, the operator can also conveniently administer medicine during the process of inserting the tracheal tube, and by using medicine locally in the trachea, the excessive stress reaction caused by the tracheal tube stimulating the trachea can be eliminated, and by using medicine in the bronchus, the effect of local precise medicine use can be achieved, and some concurrent diseases such as bronchial asthma attack can be treated.

[0097] The multifunctional tracheal tube of the present application provides a variety of use functions in one on the basis of ensuring the ventilation function of the tracheal tube as a basic artificial airway, so as to become a multifunctional tracheal tube capable of meeting a variety of use requirements.

[0098] Among them, Figure 1 The dashed line in the main tube 1 indicates that the corresponding structure is located in the tube, and since the main tube 1 is a relatively long tubular structure, the structures of the longer part of the tube body are the same, in order to make those skilled in the art more conveniently understand the structure of the multifunctional tracheal tube, the main tube 1 in Figure 1 The main tube 1 is drawn as a broken line composed of hyperbolas, hiding part of the tube structure, and does not limit the length of the main tube 1 and the internal components of the main tube 1 in the actual multifunctional tracheal tube. Figure 2A 、 Figure 2B AndFigure 5A The oblique lines in the figure represent the cross-sectional lines.

[0099] In this embodiment, the first spray tube 3 can be used as an endotracheal spray tube for endotracheal medication, and the second spray tube 4 can be used as a bronchial spray tube for bronchial medication.

[0100] The basic length, diameter and structure of the main tube 1 in this embodiment can be consistent with those of various types of conventional endotracheal tubes.

[0101] In this embodiment, the gas outlet 11 of the main tube 1 is a partial lateral opening, and the opening direction of the partial lateral opening is different from the axis of the main tube 1 and points to the oblique side of the main tube 1.

[0102] In this embodiment, the gas outlet 11 can be a Figure 1 The inclined arc surface structure (i.e., the gas outlet is a crescent-shaped arc surface, and the opening direction is obliquely downward) shown in the figure can also be an inclined plane structure.

[0103] The signal transmission line containing cavity 21 is located on the long side of the main tube 1, the lens of the miniature camera 2 points to the short side of the main tube 1, and the angle between the lens of the miniature camera 2 and the long side of the main tube 1 is less than 30 degrees. In this embodiment, the miniature camera 2 is located at the same height as the highest point of the edge of the gas outlet 11 (i.e., the oblique edge of the gas outlet 11 of the main tube 1 is located at the same height as the lens of the miniature camera 2, and the angle between the lens of the miniature camera 2 and the long side of the main tube 1 is less than 30 degrees).

[0104] By installing the miniature camera 2 in the signal transmission line containing cavity on the long side of the main tube and allowing the angle between the lens of the miniature camera 2 and the long side of the main tube 1 to be less than 30 degrees, the lens can be effectively prevented from being covered by sputum, and the position of the miniature camera 2 can be referred to in the figures. Figure 2B and Figure 3

[0105] In this embodiment, the lower opening of the signal transmission line containing cavity 21 can also be an inclined opening, and the opening direction of the lower opening of the signal transmission line containing cavity 21 is consistent with the direction of the lens of the miniature camera 2.

[0106] ​Through the structural design, the miniature camera 2 is arranged in the signal transmission line containing cavity 21 on the long side of the main body tube 1, so that the lens of the miniature camera 2 is protected by the tube wall and is not directly contacted and covered by the sputum in the trachea, and the image display is not affected, and the lens is a deflection angle type, and in actual application, the lens can be deflected by 10-30 degrees to the opposite side of the tube wall at the lens position, so that the view is not affected by the shielding of the distal tube wall on the lens position side when the view is observed longitudinally, and the maximum effective view is ensured, and through the real-time observation of the visual lens, the catheter can be accurately positioned, and other treatment devices such as a bronchial occlusion tube, a sputum suction tube and a bronchoscope can be accurately guided to enter the left or right target bronchus.

[0107] The long side of the main body tube 1 is the side of the main body tube 1 located at the lowest point of the edge of the air outlet 11, and the short side of the main body tube 1 is the side of the main body tube 1 located at the highest point of the edge of the air outlet 11.

[0108] The miniature camera 2 is connected with the display connection plug 22 outside the main body tube 1 through the connecting line arranged in the signal transmission line containing cavity 21, and can be connected with external display equipment through the display connection plug 22. The connecting line can be a video and light source connecting line.

[0109] The miniature camera 2 is embedded in the lower opening of the signal transmission line containing cavity 21, the video and light source connecting line is led out to the outer wall of the catheter at the air inlet end through the signal transmission line containing cavity 21, and the display can be connected to display the image through the electronic interface.

[0110] In specific implementation, the lens of the miniature camera 2 can also be arranged in the signal transmission line containing cavity 21 at a position away from the lower opening of the transmission line containing cavity 21 by a preset distance, so as to better protect the lens of the miniature camera 2.

The liquid outlet of the liquid outlet channel 91 is a horizontal liquid outlet.

[0115] Through the design of the spray port, the liquid in the high-pressure and high-speed state in the main tube of the first spray tube or the second spray tube can be sprayed to the smooth arc surface on the side wall of the first groove 92 through the liquid outlet channel 91, so that the atomization effect is generated.

[0116] In this embodiment, the multifunctional tracheal catheter further comprises a gas bag 5 and a gas bag inflation tube 51.

Figure 5B It is a partial enlarged view of the spray port in a spray tube of the multifunctional tracheal catheter in an embodiment of the present application. Since the structure of the lower opening 31 of the first spray port is basically the same as that of the lower opening 41 of the second spray tube, only the structure schematic diagram of the lower opening of one spray tube is drawn. From the structure schematic diagram of the lower opening of the first spray tube, it can be seen that the lower opening 31 of the first spray tube is in a circular recess shape, and the side wall edge of the lower opening 31 is in a smooth arc surface.

Through such a structure design, when the liquid is pressurized and output from the port, the high-pressure and high-speed liquid is sprayed to the opposite smooth protruding arc surface, so that the atomization effect is generated, thereby the effect of intratracheal atomization of medicine can be achieved.

[0118] In clinical use, each spray tube only needs to be connected with the corresponding syringe, and then the effective atomization effect can be generated by pressurized injection. In actual operation, the corresponding drug treatment can be performed according to the clinical needs.

During operation, only the closure cover 65 needs to be opened, and then the corresponding instrument can be inserted. During the process of not inserting other instruments, the closure cover 65 can play a role in sealing, etc., and during the process of inserting these instruments into the human body, the funnel-shaped elastic valve film 64 wraps the instruments and seals the anti-splashing working interface 63, which can prevent the tracheal secretions from being vertically sprayed to the operator and the operating environment due to coughing, thereby playing a role in isolating the pollutants in the trachea.

[0134] In this embodiment, the anti-splashing working interface 63 is coaxially arranged with the main tube gas inlet interface 62, and the anti-splashing working interface 63 is located on the upper side of the main tube gas inlet interface 62.

[0142] The multifunctional tracheal catheter processing device in the above embodiment can be used to process the multifunctional tracheal catheter in the above embodiment. The multifunctional tracheal catheter processing method includes the following steps:

[0143] The first spray pipe 3 and the second spray pipe are made in the main pipe 1 body. The manufacturing steps of each spray port are as follows:

[0144] The insertion tool 81 is inserted into the corresponding main pipe body from the direction of the main pipe inlet;

[0145] The position of the spray port in the main pipe 1 body is heat processed;

[0146] The protrusion in the insertion tool 81 is inserted into the position where the liquid outlet channel 91 is arranged in the main pipe wall;

[0147] The insertion tool 81 is inserted into the main pipe 1 body through the inlet of the main pipe 1 body, and the processing end of the insertion tool 81 is located at the position where the spray port is arranged in the main pipe 1 body, that is, the insertion tool 81 is placed at the position as shown in Figure 7 Figure 7 It is an embodiment of the relative position of the spray port processing assembly and the main pipe body during processing.​​​

[0148] The processing end of the compression mold 82 is pressed from the outside of the wall of the main tube 1 to the processing end of the insertion mold 81, so that the protrusion 811 on the insertion mold 81 is embedded in the second groove 821 in the compression mold 82 to form a corresponding first groove 92 at a corresponding position on the wall of the main tube; that is, the compression mold 82 is inserted in the direction of the arrow in FIG. 8 to the wall of the main tube 1, so that the insertion mold 81 and the compression mold 82 are in the state shown in FIG. 8. Figure 7 Figure 8A Figure 8B FIG. 8 is a schematic view of the relative positions of the spray port processing assembly and the main tube in a second state during processing of the main tube in an embodiment. Figure 8A FIG. 8 is a schematic view of the relative positions of the spray port processing assembly and the main tube in a second state during processing of the main tube in an embodiment. Figure 8B FIG. 8 is a schematic view of the relative positions of the spray port processing assembly and the main tube in a second state during processing of the main tube in an embodiment. Figure 8A FIG. 8 is a schematic view of the relative positions of the spray port processing assembly and the main tube in a second state during processing of the main tube in an embodiment.

[0149] The embedded positions of the insertion mold 81 and the compression mold 82 in the main tube 1 are locally heated, the positions of the main tube 1 where the corresponding spray ports are to be arranged are reshaped, and the main tube 1 is cooled after the reshaping to process the corresponding spray ports.

[0150] The compression mold 82 is removed, and the insertion mold 81 is extracted.

[0151] That is, the processing object in the manufacturing process is a five-cavity primary tube manufactured by a tube drawing machine, and the secondary thermal processing of the spray port is performed before the processing of other accessories of the tracheal tube. The support tube is inserted into the tracheal tube first, and then the insertion mold 81 is inserted into the opening position of the spray tube at the tracheal tube inlet. The compression mold 82 is pressed from the outside of the wall of the main tube 1 to the tip of the insertion mold 81, so that the tip of the insertion mold 81 is embedded in the groove of the compression mold 82, and the local heating and reshaping are performed. After the reshaping, the main tube 1 is cooled, the compression mold 82 is removed, and the insertion mold 81 is extracted, and the spray port is manufactured. In this embodiment, the support tube is used to fix the main tube 1, so that the subsequent processing can be more convenient.

[0152] In the processing of the multifunctional tracheal tube, the tube body is manufactured as a five-cavity tube, including the ventilation cavity in the main tube 1, the signal transmission line containing cavity 21, the tube cavity of the first spray tube 3, the tube cavity of the second spray tube, and the tube cavity of the airbag inflation tube 51. The signal transmission line containing cavity 21, the tube cavity of the first spray tube 3, the tube cavity of the second spray tube, and the tube cavity of the airbag inflation tube 51 are in-wall tubes in the main tube 1, and the five-cavity tube can be manufactured by a tube drawing machine. The above method is used to open the corresponding spray ports of the first spray tube 3 and the second spray tube, and then the installation of the miniature camera 2 and the installation of the anti-splashing three-way joint 6 are further completed. Since the installation of other components can be performed by conventional processing technology, details are not described here.​​

[0153] The five-cavity tube of the multifunctional tracheal catheter can be made of medical plastic material.

[0154] The spray port with the first groove 92 and the liquid outlet channel 91 in a circular recess shape can be very conveniently made by the spray port processing assembly in the above embodiment in cooperation with the preparation method of the multifunctional tracheal catheter.

[0155] The multifunctional tracheal catheter of the embodiment can be selected and used by patients in need of tracheal intubation for respiratory treatment, and has a wide application scenario.

[0156] The multifunctional tracheal catheter of the embodiment has the following technical effects:

[0157] After the tracheal catheter is shaped with a commonly used metal guide core, the oral cavity is opened, a general laryngeal mirror is used, and the image display of the miniature camera 2 is used to sequentially send the tracheal catheter into the oral cavity, the throat, and the glottis. After the glottis is exposed, the tracheal catheter is sent into the trachea, and under the image guidance, the tracheal catheter is fixed at a suitable position on the carina in the trachea.

[0158] After the tracheal catheter is fixed, the local anesthetic required for use can be injected into the trachea through the tracheal injection spray tube (i.e., the first spray tube 3) on the air bag 5 by using a syringe under pressure in the state that the air bag 5 is deflated. The drug solution is sprayed in the form of atomization at the spray port, at this time, the atomized drug solution can cover the gap around the catheter and the air bag 5, so that the tracheal mucosa of the contact surface is affected by the local anesthetic, and a local anesthetic effect is generated. As a result, the excessive stress reaction generated by the contact between the tracheal catheter and the trachea can also be eliminated. After the air bag 5 is inflated, normal respiratory support treatment can be performed. When bronchial inhalation treatment is required, such as bronchodilator, hormone, etc., an injection syringe can be connected to the bronchial injection spray tube (i.e., the second spray tube) under pressure at any time as needed, so that it enters the deep tissue of the two lungs through the bronchus, and produces a clinical pharmacological effect through local and systemic absorption.

[0159] In the tracheal intubation state, when a bronchial occlusion tube is needed for thoracic surgery (or other surgeries requiring bronchial occlusion tube placement), by cooperating with the working port of the anti-splashing tee joint 6, the closure cover 65 of the anti-splashing tee joint is opened, and the occlusion tube is inserted through the funnel-shaped valve membrane under the closure cover 65. Due to the inward folding of the distal end outlet of the catheter to the central lumen, the occlusion tube can be sent to the target bronchus on the left or right side in the preset direction, and the precise bronchial endoscope is completed. Due to the elastic wrapping and isolation of the funnel-shaped valve membrane 603 to the occlusion tube, even if the patient has a cough, the airway secretions will not be sprayed out of the closed pipeline system, avoiding the possibility of contamination of the operator and the surrounding environment by the patient's respiratory tract secretions. At this time, the occlusion tube can be easily sent to the target bronchus with the help of the image display at the distal end. Due to the use of the anti-splashing tee joint 6, the production of the occlusion tube can be greatly simplified, and a general thin tracheal catheter extension can meet the functional needs and greatly reduce the cost compared with the existing occlusion tube such as Tampa. It is effective and economical.

[0160] The anti-splashing tee joint 6 used with the catheter can open the closure cover 65 at the working port when needed, and place treatment bodies such as occlusion tubes, sputum suction tubes, and bronchoscopes through it. When such treatment bodies are inserted into the trachea of a patient, coughing may occur, which can cause the patient's airway secretions to be sprayed out of the pipeline and contaminate the operating environment and the operator. Due to the elastic wrapping of the funnel-shaped valve membrane to the inserted treatment body, an effective isolation effect can be achieved. This structure has good protection and protection effect when used in the treatment of respiratory system diseases, especially in the treatment of patients with diseases such as new crown and SARS.

[0161] The above-mentioned multifunctional tracheal catheter can meet the requirements of various functions of the tracheal catheter, facilitate the selection of various functions by clinicians, improve the convenience of use, and provide a solution to reduce the physiological disturbance of the tracheal catheter to the patient, and protect clinicians from possible iatrogenic contamination during use.

[0162] Patients who need tracheal intubation for treatment can choose to use the visible multifunctional tracheal catheter.

[0163] Before use, check that the tracheal catheter air bag 5 is inflated without air leakage, deflate the air bag 5 after confirmation, check the connection of the miniature camera 2 to the display, confirm that the image display is normal, connect the spray tube injector interface to the injector, inject physiological saline under pressure, and observe the normal spray effect before use.

[0164] After the patient is prepared for tracheal intubation in a supine position, the tracheal intubation operation is started, the power display is turned on, the mouth of the patient is opened, the tracheal tube is inserted into the guide core to be about 90 degrees at the distal end, the tracheal tube can be used in cooperation with a common direct laryngoscope, one hand holds the air inlet end of the tracheal tube, under the guidance of the video image, the air outlet end 11 of the tracheal tube is placed through the oral cavity, reaches and displays the glottis through the oral cavity and throat, the air outlet end of the tracheal tube is aligned with the glottis and inserted, the tracheal tube is made to enter the trachea, under the guidance of the image, the tracheal tube is sent to 2-3 cm above the carina in the trachea, the tracheal tube is fixed outside the mouth at the incisor part by means of a mouth guard, a splash-proof tee joint is connected, a breathing circuit is connected, the air bag 5 is inflated through the air bag inflation interface 52, and artificial ventilation treatment can be implemented.

[0165] According to the depth of anesthesia and the intubation reaction of the patient, when intratracheal mucosal surface anesthesia is needed, the air bag 5 is deflated first, the syringe containing local anesthetic is connected to the syringe interface of the spray tube, so that it passes through the intratracheal spray tube, the local anesthetic is sprayed in a atomized state from the spray port of the intratracheal spray tube and covers the gap around the tracheal tube through the method of pressure injection, which plays a role in intratracheal mucosal surface anesthesia and eliminating excessive stress reaction, after the injection is completed, the air bag 5 is inflated again to restore the normal ventilation mode, when intratracheal medication is needed, the syringe containing therapeutic drugs is connected to the intratracheal spray tube interface through the intratracheal spray tube, and the drug is atomized and sprayed from the intratracheal spray port and enters the deep respiratory tract tissue through pressure injection, so as to produce local pharmacological effect, and the drug absorbed through the deep tissue can also produce systemic pharmacological effect.

[0166] And through the design of the splash-proof tee joint, the operator can be effectively protected, and the situation that the respiratory tract secretions of the patient may contaminate the operator and the surrounding environment is avoided.

[0167] The above describes the preferred embodiments of the application in detail. It should be understood that those skilled in the art can make many modifications and changes to the application without creative labor based on the concept of the application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment based on the prior art according to the concept of the application shall be within the protection scope determined by the claims.
