Description

Technical Field

[0001] The present invention relates to the field of rigid bronchoscope equipment in respiratory and interventional treatment surgeries, and in particular to a rigid bronchoscope sheath applicable to multiple scenarios. Background Art

[0002] A rigid bronchoscope is a type of modern medical equipment that is inserted into the human body to diagnose and treat respiratory diseases. In order to insert the endoscope, a sheath must first be inserted into the human respiratory tract to facilitate smooth insertion of the endoscope. A joint is fixed at the distal end of the sheath, and the endoscope can be inserted into the sheath through the joint opening. The sheath joint can protect structures such as the supraglottic airway and keep the airway open.

[0003] In the existing technical solutions, for example, the visual rigid bronchoscope disclosed in the publication number CN215227456U. The above-mentioned rigid bronchoscope sheath has only two channels, namely the operation channel and the single-way ventilation input port, which are specifically located at the proximal position of the bronchoscope body, a high-frequency ventilator interface connected to the high-frequency ventilator, and an anesthesia ventilator interface connected to the anesthesia ventilator. Because the rigid bronchoscope sheath in the prior art has only 2 or 3 channels, 2 channels usually include an operation channel and a single-way ventilation input port, and 3 channels usually include an operation channel, a single-way ventilation input port and a bypass gas adjustment inlet. Therefore, the existing mirror sheath can only realize single-way normal frequency ventilation input or high frequency ventilation input, and cannot realize normal frequency and high frequency superimposed ventilation. If medical workers in this field want to realize superimposed ventilation, or freely control the function switching of normal frequency ventilation input and high frequency ventilation input, they also need to match the adapter accessories. The above-mentioned adapter accessories will not only cause the change of ventilation position, thereby affecting the effect of ventilation, but also increase the complexity of the operation of the equipment, and the accessories need to be replaced frequently. In addition, in the prior art, the sheaths on the market do not have airway monitoring channels, and cannot achieve real-time monitoring of the pressure in the human airway, the end-tidal carbon dioxide concentration, and the airway oxygen concentration. This results in that in clinical use, the patient's real-time condition can only be observed through a monitor, or connected to the equipment for monitoring through an endotracheal tube, resulting in the problem of the lack of functionality of the existing rigid bronchoscope sheaths.

[0004] Therefore, technicians in this field are in urgent need of a new rigid bronchoscope sheath that can be applied to different scenarios and can realize single normal frequency ventilation input, high frequency ventilation input, and normal frequency and high frequency superimposed ventilation input. At the same time, it can also simultaneously realize the monitoring of airway pressure in the airway, end-tidal carbon dioxide concentration, airway oxygen concentration and other data monitoring. It can also be connected to bypass gas as needed, so as to assist heating and humidification, or external anesthetic gas, etc. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is how to solve the problem that the rigid bronchoscope sheath in the prior art has a single function and cannot meet the medical needs in different scenarios. To this end, the present invention provides a rigid bronchoscope sheath applicable to multiple scenarios, including:

[0006] The lumen of the sheath body;

[0007] A dual-channel ventilation input airway, arranged on the lumen of the sheath body, which includes: a ventilation input airway interface and two independent input airway pipelines; the two input airway pipelines are respectively communicated with the ventilation input airway interface to achieve separate conventional frequency ventilation input function, separate high-frequency ventilation input function, and conventional frequency-high frequency superimposed ventilation input function.

[0008] Optionally, a dual-channel output gas sampling airway is also arranged on the lumen of the sheath body, which includes: an output gas sampling airway interface and two independent output airway pipelines; the two output airway pipelines include: a gas analysis and collection pipeline and a gas path pressure collection pipeline. The above gas analysis and collection pipeline is used to detect the end-tidal carbon dioxide concentration and airway oxygen concentration data, and the gas analysis and collection pipeline is used to monitor the airway pressure in the output airway pipeline.

[0009] Optionally, the two input airway pipelines are respectively communicated with the lumen of the sheath body and are located at the proximal position of the lumen of the sheath body close to the inlet;

[0010] The two output airway pipelines are respectively communicated with the lumen of the sheath body and are located at the distal position of the lumen of the sheath body close to the outlet.

[0011] Optionally, on the outer peripheral wall of the lumen of the sheath body, a conventional frequency ventilation input port and a high-frequency ventilation input port communicated with the conventional frequency ventilation input pipeline and the high-frequency ventilation input pipeline are respectively preset;

[0012] On the outer peripheral wall of the lumen of the sheath body, an airway gas analysis and detection port and an airway pressure detection port communicated with the gas analysis and collection pipeline and the gas path pressure collection pipeline are respectively preset.

[0013] Optionally, the connection angle between the conventional frequency ventilation input pipeline and / or the high-frequency ventilation input pipeline and the outer peripheral wall of the lumen of the sheath body is an acute angle. The two input airway pipelines, namely the conventional frequency ventilation input pipeline and the high-frequency ventilation input pipeline, are inserted into the lumen of the sheath body at a small acute angle, so that the gas in the input airway generates the Venturi effect, and relevant data are obtained by fluid analysis, so that most of the gas is led to the distal position of the lumen of the sheath body close to the outlet, and then diverges in the patient's airway to achieve the best superimposed ventilation effect.

[0014] The connection angle between the gas analysis and collection pipeline and / or the gas path pressure collection pipeline and the outer peripheral wall of the lumen of the sheath body is an acute angle. The two output gas sampling airways, namely the gas analysis and collection pipeline and the gas path pressure collection pipeline, are inserted into the lumen of the sheath body at a small acute angle. The gas flowing forward into the patient's body will not be discharged from the output gas sampling airway, but only the gas exhaled backward from the human airway will be collected to obtain more accurate collection data.

[0015] Optionally, the conventional ventilation input pipeline is fixedly welded to the lumen of the sheath body so that the conventional ventilation input pipeline is communicated with the conventional ventilation input port; and / or,

[0016] The high-frequency ventilation input pipeline is fixedly welded to the lumen of the sheath body so that the high-frequency ventilation input pipeline is communicated with the high-frequency ventilation input port.

[0017] Optionally, the gas analysis and collection pipeline is fixedly welded to the lumen of the sheath body so that the gas analysis and collection pipeline is communicated with the airway gas analysis detection port; and / or,

[0018] The gas path pressure collection pipeline is fixedly welded to the lumen of the sheath body so that the gas path pressure collection pipeline is communicated with the airway pressure detection port.

[0019] Optionally, the rigid tracheoscope sheath applied to multiple scenarios further includes:

[0020] A bypass gas interface located on the side of the lumen of the sheath body and communicated with the lumen of the sheath body; the bypass gas interface is used to connect a humidifier or an anesthesia machine.

[0021] Optionally, the bypass gas interface is obliquely connected to the lumen of the sheath body, and the dual-channel ventilation input airway and the output gas sampling airway are respectively located on both sides of the bypass gas interface.

[0022] Optionally, at the distal position of the lumen of the sheath body near the outlet, there is also an opening for ventilating the contralateral lung during ventilation; and / or,

[0023] The lumen of the sheath body is a straight-through thin-walled tube with a thickness of 0.3 mm to 1.2 mm; the above-mentioned straight-through thin-walled tube can more easily penetrate into the human airway and can be applied to people with smaller airways; and / or,

[0024] The distal end of the lumen of the sheath body is formed with an inclined opening; through the above-mentioned inclined opening, it is easier to expand and penetrate into the airway, and at the same time, it will not damage the airway.

[0025] Optionally, the opening is a waist-shaped hole extending in the reverse direction of the length of the lumen of the sheath body.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The rigid bronchoscope sheath applicable to multiple scenarios provided by the present invention includes: a main sheath lumen; a dual-channel ventilation input airway provided on the main sheath lumen, which includes: a ventilation input airway interface, and two independent input airway tubes; the two input airway tubes are respectively communicated with the ventilation input airway interface to achieve a separate constant-frequency ventilation input function, a separate high-frequency ventilation input function, and a constant-frequency and high-frequency superimposed ventilation input function.

[0028] In the present invention, by providing two independent input airway tubes on the main sheath lumen, it can effectively solve the problem that the rigid bronchoscope sheath in the prior art has a single function. If medical workers want to achieve superimposed ventilation or freely control the function switching between constant-frequency ventilation input and high-frequency ventilation input, they also need to be equipped with adapter accessories. The above-mentioned adapter accessories will not only cause changes in the ventilation position and thus affect the ventilation effect, but also increase the complexity of equipment operation, resulting in the problem that the accessories need to be frequently replaced. In the present invention, medical workers can freely switch according to needs through the above-mentioned dual-channel ventilation input airway: a separate constant-frequency ventilation input function, a separate high-frequency ventilation input function, and a constant-frequency and high-frequency superimposed ventilation input function. Among them, through the above-mentioned constant-frequency and high-frequency superimposed ventilation input, the advantage of superimposed ventilation can be exerted during the breathing and interventional treatment operations. Through the superimposed ventilation of high frequency and constant frequency, the retention of carbon dioxide can be effectively reduced.

[0029] 2. The rigid bronchoscope sheath applicable to multiple scenarios provided by the present invention further includes: an output gas sampling airway provided on the main sheath lumen, and the output gas sampling airway is used to detect relevant data of the output gas. The output gas sampling airway is a dual-channel airway, including: an output gas sampling airway interface, and two independent output airway tubes; the output airway tubes include: a gas analysis and collection tube and a gas path pressure collection tube.

[0030] In the present invention, the airway pressure in the airway, as well as data such as the end-tidal carbon dioxide concentration and airway oxygen concentration in the airway can be simultaneously monitored through the above-mentioned gas analysis and collection tube and gas path pressure collection tube. In addition, for a ventilator without a monitoring function, it can also be externally connected to relevant monitoring devices or instruments for monitoring work.

[0031] 3. For the rigid bronchoscope sheath applicable to multiple scenarios provided by the present invention, the two output airway tubes are respectively communicated with the main sheath lumen and are located at the distal position of the main sheath lumen close to the outlet; the two input airway tubes are respectively communicated with the main sheath lumen and are located at the proximal position of the main sheath lumen close to the inlet.

[0032] In the present invention, while solving the problems that the existing mirror sheaths cannot be stacked for ventilation and the gas path lacks a monitoring port, the positions of the mirror sheaths for ventilation input and gas path monitoring are optimized. Two output airway pipelines are respectively connected to the airway gas analysis and detection port and the airway pressure detection port. Additionally, two input airway pipelines are respectively connected to the conventional frequency ventilation input port and the high-frequency ventilation input port. As a result, the positions of the ventilation port and the detection port are deeper, enabling the delivery of gas to a deeper position, ensuring the pressure of the ventilation input, and simultaneously being able to monitor the gas in the deeper airway, and the collected data is more accurate.

[0033] 4. For the rigid tracheoscope sheath applicable to multiple scenarios provided by the present invention, the connection angle between the conventional frequency ventilation input pipeline and / or the high-frequency ventilation input pipeline and the outer peripheral wall of the main tube cavity of the mirror sheath is an acute angle.

[0034] The two input airway pipelines, namely the conventional frequency ventilation input pipeline and the high-frequency ventilation input pipeline, are inserted into the connection with the main tube cavity of the mirror sheath at a small acute angle, causing the Venturi effect for the gas in the input airway. Relevant data is obtained through fluid analysis, enabling most of the gas to be led to the distal position near the outlet of the main tube cavity of the mirror sheath and then dispersed in the patient's airway, achieving the best effect of superposed ventilation.

[0035] In addition, the connection angle between the gas analysis and collection pipeline and / or the gas path pressure collection pipeline and the outer peripheral wall of the main tube cavity of the mirror sheath is an acute angle.

[0036] The two output gas collection airways, namely the gas analysis and collection pipeline and the gas path pressure collection pipeline, are inserted into the connection with the main tube cavity of the mirror sheath at a small acute angle. The gas flowing forward into the patient's body will not be discharged from the output gas collection airway, but only the gas exhaled backward from the human airway is collected to obtain more accurate collected data.

[0037] The above settings of the positions and angles of the dual-channel ventilation input airways can enable the jet gas to enter deeper into the human airway to ensure the flow rate of the jet gas and enable better oxygenation of the human body. At the same time, the positions and angles of the output gas collection airways of the dual-channel airways can more accurately collect and monitor data such as the airway pressure, end-tidal carbon dioxide concentration, and airway oxygen concentration in the human airway.

[0038] 5. The rigid tracheoscope sheath applicable to multiple scenarios provided by the present invention further includes: a bypass gas interface, which is located on the side of the main tube cavity of the mirror sheath and is connected to the main tube cavity of the mirror sheath; the bypass gas interface is used to connect a humidifier or an anesthesia machine.

[0039] Through the above bypass gas interface, heated and humidified gas can be provided as needed, or external anesthesia gas can be connected. Moreover, in this solution, the operation channels for guiding and introducing the optical mirror or surgical instruments are still reserved. This channel avoids tracheal intubation, reduces the damage to the patient, ensures the intraoperative vision, provides the operation space for laser surgery and other surgeries, and makes the surgical process safer.

[0052] Embodiment 1

[0053] Refer to Figure 1 , Figure 2 and Figure 7 as shown, Figure 1 which shows the three-dimensional structural schematic diagram of the rigid tracheoscope sheath in the embodiment of the present invention. Figure 2 which shows the front view of the rigid tracheoscope sheath in the embodiment of the present invention. Figure 7 which shows the schematic diagram of the gas flow direction in the rigid tracheoscope sheath in the embodiment of the present invention.

[0054] A rigid tracheoscope sheath applicable to multiple scenarios provided in this embodiment includes:

[0055] The main lumen 1 of the sheath body is a straight pipe structure;

[0056] The dual-channel ventilation input airway 2 is provided on the lumen 1 of the mirror sheath main body, and includes: a ventilation input airway interface 3, and two independent input airway pipelines 4; the two input airway pipelines 4 are respectively communicated with the ventilation input airway interface 3 to realize the functions of separate constant-frequency ventilation input, separate high-frequency ventilation input, and constant-frequency and high-frequency superimposed ventilation input.

[0057] Specifically, as Figure 3 shown in the side view of the rigid tracheoscope sheath, and as Figure 5 shown in the schematic diagram of the setting positions of the constant-frequency ventilation input port and the high-frequency ventilation input port. The two above-mentioned input airway pipelines 4 are respectively communicated with the lumen 1 of the mirror sheath main body and are located at the proximal position of the lumen 1 of the mirror sheath main body close to the inlet. Moreover, on the outer peripheral wall of the lumen 1 of the mirror sheath main body, a constant-frequency ventilation input port 14 and a high-frequency ventilation input port 15 communicated with the constant-frequency ventilation input pipeline 10 and the high-frequency ventilation input pipeline 11 are respectively preset.

[0058] It can be understood that the above embodiment does not specifically limit the shape and structure of the lumen 1 of the mirror sheath main body. In an optional embodiment, the shape of the lumen 1 of the mirror sheath main body can be various, for example: a straight tube, a bent tube, or a combination of a straight tube and a bent tube.

[0059] It can be understood that the above embodiment does not specifically limit the shape and structure of the lumen 1 of the mirror sheath main body. In an optional embodiment, the size of the lumen 1 of the mirror sheath main body can have various specifications, various thickness specifications, variable diameter or variable cross-section, and the length can have various specifications to be suitable for various populations.

[0060] It can be understood that the above embodiment does not specifically limit the connection structure of the lumen 1 of the mirror sheath main body. In an optional embodiment, the lumen 1 of the mirror sheath main body can be integral, or it can be split, detachable, and replaceable with an interface.

[0061] In some more specific embodiments, as Figure 1 shown, the rigid tracheoscope sheath applied to multiple scenarios further includes: an output gas sampling airway 5, which is provided on the lumen 1 of the mirror sheath main body, and the output gas sampling airway 5 is used to detect relevant data of the output gas.

[0062] Specifically, as Figure 4 shown in the side view of the rigid tracheoscope sheath, and as Figure 6 shown in the schematic diagram of the setting positions of the airway gas analysis detection port and the airway pressure detection port. The output gas sampling airway 5 is a dual-channel airway, including: an output gas sampling airway interface 6, and two independent output airway pipelines 7;

[0063] The output airway tube 7 includes: a gas analysis and collection tube 8 and a gas path pressure collection tube 9. The above-mentioned gas analysis and collection tube 8 is used to detect the end-tidal carbon dioxide concentration and airway oxygen concentration data, and the gas analysis and collection tube 8 is used to monitor the airway pressure inside the output airway tube 7.

[0064] Specifically, the two output airway tubes 7 are respectively connected to the lumen of the mirror sheath main body 1 and are located at the distal end of the lumen of the mirror sheath main body 1 close to the outlet. Moreover, on the outer peripheral wall of the lumen of the mirror sheath main body 1, an airway gas analysis and detection port 12 and an airway pressure detection port 13 communicating with the gas analysis and collection tube 8 and the gas path pressure collection tube 9 are respectively preset.

[0065] In some more specific embodiments, such as Figure 1 and Figure 2 As shown, the rigid tracheoscope sheath applied to multiple scenarios further includes: a bypass gas interface 16, the bypass gas interface 16 is located on the side of the lumen of the mirror sheath main body 1 and is connected to the lumen of the mirror sheath main body 1; the bypass gas interface 16 is used to connect a humidifier or an anesthesia machine.

[0066] Specifically, the bypass gas interface 16 is obliquely connected to the lumen of the mirror sheath main body 1, and the dual-channel ventilation input airway 2 and the output gas collection airway 5 are respectively located on both sides of the bypass gas interface 16.

[0067] In some more specific embodiments, such as Figure 2 As shown, the connection angle between the conventional frequency ventilation input tube 10 and the high-frequency ventilation input tube 11 and the outer peripheral wall of the lumen of the mirror sheath main body 1 is an acute angle. The two input airway tubes 4, namely the conventional frequency ventilation input tube 10 and the high-frequency ventilation input tube 11, are inserted into the lumen of the mirror sheath main body 1 at a small acute angle, causing the Venturi effect of the gas in the input airway, obtaining relevant data through fluid analysis, leading most of the gas to the distal end of the lumen of the mirror sheath main body 1 close to the outlet, and then diverging in the patient's airway to achieve the best superposition ventilation effect.

[0068] It can be understood that for the conventional frequency ventilation input tube 10 and the high-frequency ventilation input tube 11 in the above embodiments, the connection angle between the two and the outer peripheral wall of the lumen of the mirror sheath main body 1 is not specifically limited. In an alternative embodiment, the connection angle between the conventional frequency ventilation input tube 10 and the high-frequency ventilation input tube 11 and the outer peripheral wall of the lumen of the mirror sheath main body 1 can also be other angles than acute angles.

[0069] In some more specific embodiments, such as Figure 2As shown, the connection angle between the gas analysis and collection pipeline 8 and the gas path pressure collection pipeline 9 and the outer peripheral wall of the main lumen 1 of the sheath is an acute angle. The two output gas sampling airways 5, namely the gas analysis and collection pipeline 8 and the gas path pressure collection pipeline 9, are inserted into the main lumen 1 of the sheath at a small acute angle. The gas flowing forward into the patient's body will not be discharged from the output gas sampling airway 5, but only the gas exhaled backward from the human airway is collected to obtain more accurate collection data.

[0070] It can be understood that in the above embodiments, no specific limitation is imposed on the connection angle between the gas analysis and collection pipeline 8 and the gas path pressure collection pipeline 9 and the outer peripheral wall of the main lumen 1 of the sheath. In an alternative embodiment, the connection angle between the gas analysis and collection pipeline 8 and the gas path pressure collection pipeline 9 and the outer peripheral wall of the main lumen 1 of the sheath can also be other angles than acute angles.

[0071] In some more specific embodiments, such as Figure 2 As shown, the gas analysis and collection pipeline 8 is fixedly welded to the main lumen 1 of the sheath so that the gas analysis and collection pipeline 8 is communicated with the airway gas analysis detection port 12; the gas path pressure collection pipeline 9 is fixedly welded to the main lumen 1 of the sheath so that the gas path pressure collection pipeline 9 is communicated with the airway pressure detection port 13; the conventional frequency ventilation input pipeline 10 is fixedly welded to the main lumen 1 of the sheath so that the conventional frequency ventilation input pipeline 10 is communicated with the conventional frequency ventilation input port 14; the high-frequency ventilation input pipeline 11 is fixedly welded to the main lumen 1 of the sheath so that the high-frequency ventilation input pipeline 11 is communicated with the high-frequency ventilation input port 15.

[0072] It can be understood that in the above embodiments, no specific limitation is imposed on the connection and fixation method between the gas analysis and collection pipeline 8, the gas path pressure collection pipeline 9, the conventional frequency ventilation input pipeline 10, and the high-frequency ventilation input pipeline 11 and the main lumen 1 of the sheath. In an alternative embodiment, the gas analysis and collection pipeline 8, the gas path pressure collection pipeline 9, the conventional frequency ventilation input pipeline 10, and the high-frequency ventilation input pipeline 11 can also be fixedly connected by means of bonding, clamping, integral molding, etc.

[0073] In some more specific embodiments, such as Figure 2 As shown, at the distal position of the main lumen 1 of the sheath near the outlet, an opening 17 for ventilating the contralateral lung during ventilation is further provided. The opening 17 is a kidney-shaped hole extending in the reverse direction of the length of the main lumen 1 of the sheath.

[0074] It can be understood that in the above embodiments, no specific limitation is imposed on the specific shape of the opening 17. In an alternative embodiment, the opening 17 can also be a circular hole or other shaped holes.

[0075] In some more specific embodiments, such as Figure 2 As shown, an inclined opening 18 is formed at the distal end of the lumen 1 of the sheath body; through the inclined opening 18, it is easier to expand and penetrate into the airway, and at the same time, the airway will not be damaged.

[0076] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
