Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a multifunctional double-lumen bronchial catheter which can be used for electrocardiogram pacing. Background Art

[0002] At present, artificial heart pacing technology has become an important part of contemporary medical emergency rescue and clinical prevention work. It has been widely used in the treatment of patients with heart disease, especially those with obvious or dangerous symptoms caused by abnormal heart rhythm. This technology can significantly improve the quality of life of patients and reduce the risk of complications caused by heart rhythm problems.

[0003] Analyzing from the existing technologies at home and abroad, there are various ways and methods of artificial cardiac pacing, for example, there are pacing methods such as transthoracic pacing or pacing by puncturing the heart through the chest wall; there are pacing methods such as puncturing the great sphenoid vein, basilic vein, subclavian vein, external jugular vein, internal jugular vein, and femoral vein to introduce endocardial catheter electrodes; there are pacing methods such as pacing by placing epicardial electrodes or myocardial electrodes through thoracotomy or upper and lower abdominal incisions. When performing cardiac pacing, the patient may have other symptoms and need symptomatic treatment. For example, if the patient has problems with the lungs, a double-lumen bronchial catheter is needed to supply air to the patient's lungs. At this time, when multiple rescue operations are performed separately, it is easy to prolong the treatment process for the patient and increase the risk that the patient cannot receive timely treatment.

[0029] Beneficial effects of the present invention:

[0030] 1. In the present invention, by setting up the ECG pacing assembly, artificial heart pacing can be completed while supplying air to the lungs. During the execution process, the ends of each pacing power line away from the first electrode are respectively connected to the positive and negative electrodes of the ECG pacemaker.

[0044] like Figures 1 to 7 As shown, a multifunctional double-lumen bronchial catheter that can be used for ECG pacing comprises:

[0045] Left bronchial tube 1, used to ventilate the left lung;

[0046] The right bronchial tube 100 is arranged on one side of the left bronchial tube 1 and is used for ventilating the right lung;

[0047] The expansion assembly 200 is sleeved on the outside of the left bronchial tube 1 and the right bronchial tube 100, and is used to fix the left bronchial tube 1 and the right bronchial tube 100 in the trachea;

[0048] The gas delivery component 300 is disposed on one side of the expansion component 200 and is used to deliver gas to the expansion component 200;

[0049] and a cardiac pacing assembly 400 for performing cardiac pacing;

[0050] Among them, the expansion component 200 has a hollow cavity 210, and the left bronchial catheter 1 and the right bronchial catheter 100 are both provided with the hollow cavity 210; the ECG pacing component 400 includes a first electrode 410, a second electrode 420, and two pacing power lines 430, and the first electrode 410 and the second electrode 420 are both installed on the surface of the right bronchial catheter 100, one end of each pacing power line 430 is respectively connected to the first electrode 410 and the second electrode 420, and each pacing power line 430 is provided with the hollow cavity 210, and the ECG pacing component 400 has a pacing state, and the ECG pacing component 400 is configured so that when it is in the pacing state, the ends of each pacing power line 430 away from the first electrode 410 are connected to the ECG pacemaker.

[0051] The invention can be used for ventilating the lungs and also for artificial heart pacing, and has multiple functions.

[0052] By setting the left bronchial catheter 1 and the right bronchial catheter 100, a double-lumen bronchial catheter can be formed to realize independent air supply to the left lung and the right lung. During air supply, the left bronchial catheter 1 and the right bronchial catheter 100 can be connected to air supply equipment such as a ventilator to complete the air supply. At the same time, before air supply, the air supply component 300 can supply air to the expansion component 200 so that the expansion component 200 expands in the trachea, thereby fixing the left bronchial catheter 1 and the right bronchial catheter 100 in the trachea, thereby preventing the left bronchial catheter 1 and the right bronchial catheter 100 from shaking during air supply and affecting the treatment process.

[0053] By setting the ECG pacing component 400, artificial heart pacing can be completed while supplying air to the lungs. During the execution process, the ends of each pacing power line 430 away from the first electrode 410 are respectively connected to the positive and negative electrodes of the ECG pacemaker. In addition, each structure in the ECG pacing component 400 is arranged outside the double-chamber bronchial catheter, wherein the first electrode 410 and the second electrode 420 are both installed on the surface of the right bronchial catheter 100, and each pacing power line 430 is arranged through the hollow cavity 210. Such a setting can prevent the ECG pacing component 400 from affecting the double-chamber bronchial catheter from supplying air to the lungs, and can also prevent the double-chamber bronchial catheter from restricting the ECG pacing component 400 from completing the artificial heart pacing operation.

[0054] It should be noted that the bronchial bifurcation is at the same level as the base of the heart and the fourth thoracic vertebra, with the heart in front and the bronchial bifurcation in the back, and the two are relatively close. If a bronchial catheter with an electrode is inserted into this part of the right bronchus through the mouth, the pulse current of the pacemaker or cardiac electrophysiological stimulator can stimulate the atrium to cause pacing, making the heart beat rhythmically with the cardiac electrophysiological stimulator, thereby achieving the purpose of artificial heart pacing.

[0055] In some embodiments, it further includes a connecting component 2, which is provided in two pieces, each connecting component 2 is installed on the left bronchial tube 1 and the right bronchial tube 100 respectively, and the connecting components 2 are all in a connecting state, and the connecting components 2 are configured to be connected to the ventilator when they are in the connecting state;

[0056] A control unit 3 is installed on each of the connecting components 2 , and the control unit 3 is used to control the air intake volume of the connecting component 2 .

[0057] As mentioned above, by setting the left bronchial catheter 1 and the right bronchial catheter 100, a double-lumen bronchial catheter can be formed to realize independent air supply to the left lung and the right lung. When supplying air, the left bronchial catheter 1 and the right bronchial catheter 100 can be connected to a gas supply device such as a ventilator to complete the gas supply. Considering that the gas supply device such as a ventilator is not easy to move, in this embodiment, the double-lumen bronchial catheter is connected to the gas supply device such as a ventilator through the connecting component 2, thereby avoiding the need to move the gas supply device such as the ventilator.

[0058] The connecting component 2 has a connecting state. When it is in the connecting state, it is connected to a gas supply device such as a ventilator. At the same time, by installing a control unit 3 on the connecting component 2, the air intake of the connecting component 2 can be controlled while the air supply to the left lung or the right lung can be separately achieved. It should be noted that the air supply to the connecting component 2 can also be restricted by clamping the connecting component 2 with a clip, but this method cannot ensure that the connecting component 2 cannot supply air. The connecting component 2 can be set as a connecting conduit.

[0059] In some embodiments, the expansion assembly 200 includes a balloon 220, which is sleeved on the outside of the left bronchial catheter 1 and the right bronchial catheter 100;

[0060] The gas delivery assembly 300 includes a gas delivery portion 310 and a gas delivery pipe 320 connected to the gas delivery portion 310 , and one end of the gas delivery pipe 320 is disposed in the airbag 220 ;

[0061] The expansion component 200 has an expansion state, and the gas delivery component 300 has a gas delivery state. When the gas delivery component 300 is in the gas delivery state, the gas delivery part 310 delivers gas to the gas delivery pipe 320 to expand the airbag 220; when the gas delivery component 300 is in the gas delivery state, the expansion component 200 is in an expansion state.

[0062] The expansion assembly 200 and the gas delivery assembly 300 can be configured as a variety of structures, and a specific structure is given in this embodiment. In this embodiment, the expansion structure in the expansion assembly 200 is configured as an airbag 220, and the gas delivery structure in the gas delivery assembly 300 is configured as a gas delivery unit 310, which can be configured as an inflator or other device, and the gas output by the gas delivery unit 310 is transferred to the airbag 220 by the gas delivery pipe 320.

[0063] For the expansion component 200 and the gas delivery component 300, the expansion component 200 has an expansion state, and the gas delivery component 300 has a gas delivery state. When the gas delivery component 300 is in the gas delivery state, the gas delivery part 310 delivers gas to the gas delivery pipe 320 to expand the airbag 220, thereby causing the expansion component 200 to enter the expansion state.

[0064] When the airbag 220 is inflated, part of the airbag 220 contacts the trachea, so that the double-lumen bronchial tube can be fixed in the trachea, thereby preventing the left bronchial tube 1 and the right bronchial tube 100 from shaking during air supply and affecting the treatment process.

[0065] In some embodiments, the expansion assembly 200 also includes an adhesive portion 230 and a plurality of restricting portions 240 disposed on the inner side of the airbag 220. The adhesive portion 230 is sleeved on the outer sides of the left bronchial catheter 1 and the right bronchial catheter 100. Both the left bronchial catheter 1 and the right bronchial catheter 100 are in contact with the adhesive portion 230. One end of each restricting portion 240 is connected to the outer wall of the adhesive portion 230, and the other end of each restricting portion 240 is disposed on the inner side of the airbag 220 and is connected to the inner surface of the airbag 220.

[0066] As mentioned above, when the balloon 220 is inflated, part of the balloon 220 contacts the trachea, so that the double-lumen bronchial tube can be fixed in the trachea, but the effect of the balloon 220 on the trachea should be noted in this process. It should be noted that bronchial intubation is a medical operation that requires highly professional skills and knowledge. Before bronchial intubation, a comprehensive assessment and examination of the patient is required, including but not limited to the patient's breathing condition, the anatomical structure of the neck and oral cavity, the state of consciousness, the degree of swelling of the larynx, etc. When inserting the bronchus, it is necessary to ensure that the size and length of the tube are appropriate to avoid damage caused by being too long or too short; at the same time, when fixing the balloon 220, attention should also be paid to the inflation volume. Too much or too little inflation may cause the balloon 220 to fail or cause damage to the trachea.

[0067] The main structure of the expansion assembly 200 is the airbag 220. When the expansion assembly 200 is in an expanded state, the airbag 220 expands to become an expanded structure. In order to limit the expansion size of the airbag 220 to prevent the airbag 220 from damaging the trachea, in this embodiment, a limiting portion 240 is added to the expansion assembly 200 to limit the expansion degree of the airbag 220.

[0068] In the expansion assembly 200, the expansion structure is the airbag 220; the bonding portion 230 is a polymer structure to polymerize the left bronchial catheter 1 and the right bronchial catheter 100, and the bonding portion 230 may have the property of stably fitting to some objects, such as the bonding portion 230 may have a sticky substance to adhere to the left bronchial catheter 1 and the right bronchial catheter 100; the limiting structure is the limiting portion 240, and the setting of the limiting portion 240 can prevent the expansion degree of the airbag 220 from exceeding the predetermined expansion degree and damaging the trachea. At the same time, due to the setting of the limiting portion 240, when air is supplied to the airbag 220, air can be supplied to the limit to avoid the expansion degree of the airbag 220 being lower than the expected expansion degree and failing to complete the operation of fixing the double-lumen bronchial catheter in the trachea.

[0069] In some embodiments, the outer side of the adhesive portion 230 has a first surface, a second surface, a third surface, and a fourth surface, one end of each limiting portion 240 is connected to the first surface, the second surface, the third surface, and the fourth surface, respectively, and the projections of the ends of each limiting portion 240 connected to the adhesive portion 230 on the first surface, the second surface, the third surface, and the fourth surface are arranged in a square array respectively;

[0070] The limiting parts 240 are all configured as elastic structures.

[0071] It is mentioned above that there are multiple limiting parts 240, and in this embodiment, a specific distribution mode of the limiting parts 240 is given. In this embodiment, the outer side of the bonding part 230 has a first surface, a second surface, a third surface and a fourth surface, and multiple limiting parts 240 with ends distributed in a square array are installed on the first surface, the second surface, the third surface and the fourth surface, so as to limit more parts of the airbag 220 during the expansion process, so as to avoid the inability to limit different parts of the airbag 220 that are expanded in different directions due to the centralized arrangement of the limiting parts 240. The limiting part 240 can be set as a traction line, and the traction line can be elastic to cause a small degree of deformation.

[0072] In some embodiments, the expansion assembly 200 and the gas delivery assembly 300 are both provided in plurality, the number of the expansion assembly 200 is the same as the number of the gas delivery assembly 300, and one end of the gas delivery tube 320 in each gas delivery assembly 300 is provided one by one at the inner side of the airbag 220 in different expansion assemblies 200;

[0073] The gas delivery components 300 also include a restraint member 330, some of which are connected to the left bronchial catheter 1 and another part of which is connected to the right bronchial catheter 100; the restraint members 330 all have a restraint cavity, and each gas delivery tube 320 is inserted into the corresponding restraint cavity.

[0074] It should be noted that when the expansion assembly 200 is set to be only single, since the part of the double-lumen bronchial catheter affected by it is limited, some parts of the double-lumen bronchial catheter may still shake during the gas delivery process and affect the treatment process.

[0075] By providing multiple expansion components 200, multiple locations of the double-lumen bronchial catheter can be fixed to prevent multiple locations on the double-lumen bronchial catheter from shaking during gas delivery and affecting the treatment process, especially the locations close to the lungs.

[0076] It should also be noted that, since different expansion components 200 are located at different positions in the trachea and face different situations, it is not convenient to use a single gas delivery component 300 to deliver gas to multiple expansion components 200; at the same time, when the gas delivery component 300 is set to be single, there are two gas delivery methods, one is that the gas delivery pipe 320 is set to be multiple and connected to the inner cavities of different airbags 220, and the other is that two adjacent airbags 220 are connected through a connecting pipe, but no matter which method is used, it affects the refined gas delivery to each airbag 220.

[0077] By providing a plurality of gas delivery components 300, gas can be delivered to each expansion component 200 individually, so as to avoid the inability to deliver gas to each airbag 220 in a refined manner, which may cause some airbags 220 to fail to complete the operation of fixing the double-lumen bronchial tube in the trachea or damage the trachea.

[0078] The restraint 330 can be used to cooperate with the hollow cavity 210 to restrict each gas pipe 320 to prevent it from being chaotically distributed in the trachea. It should be noted that the airbag 220 is provided with an opening for the gas pipe 320 to enter, and the gas pipe 320 can be slidably connected to the inner wall of the opening.

[0079] In some embodiments, a camera assembly 500 is further included, which is provided with two. The camera assembly 500 is used to capture images of the patient's bronchus. Each camera assembly 500 is installed on the left bronchial catheter 1 and the right bronchial catheter 100 respectively. The camera assembly 500 includes a camera unit 510 and an illumination unit 520 connected to the camera unit 510. The camera assembly 500 has a camera state, and the camera assembly 500 is configured to be connected to an external display device when it is in the camera state.

[0080] The camera assembly 500 includes a camera unit 510 and a lighting unit 520. The camera unit 510 can adopt existing camera equipment such as existing cameras, and the lighting unit 520 can adopt existing lighting equipment such as lighting lamps. Through the setting of the camera assembly 500, the image of the patient's bronchus can be collected and transmitted to an external display device, and the lighting lamp is set to illuminate the image to make the image clearer, so that the doctor can perform the intubation positioning operation more accurately.

[0081] The camera assembly 500 has a camera state. When it is in the camera state, it is connected to a display device such as an external display screen.

[0082] In some embodiments, the right bronchial tube 100 includes a first section 110 and a second section 120 rotatably connected to the first section 110 , the first section 110 has an air inlet, and the second section 120 has an air outlet 121 ;

[0083] The second section 120 is connected to a traction member 4 , and one end of the traction member 4 is connected to any one of the gas pipes 320 .

[0084] It should be noted that the direction of the right upper lobe opening may be different in different patients, which may result in some patients being unable to optimally align with the right lobe opening when positioning the right double-lumen bronchial tube, resulting in poor ventilation effect.

[0085] By dividing the right bronchial tube 100 into two ends, during operation, the second section 120 can be pulled and rotated by pulling the traction member 4, so that the air outlet 121 is aligned with the right lung lobe opening to avoid affecting the ventilation effect. The traction member 4 can be set as a traction line.

[0086] In some embodiments, the traction member 4 includes a plurality of traction lines, one end of each traction line is respectively connected to a different portion of the second section 120 , and the other end of each traction line is respectively connected to a different gas pipe 320 .

[0087] It should be noted that by pulling different parts of the second section 120, the second section 120 rotates at different amplitudes when the traction member 4 moves the same distance. By setting a plurality of traction lines, different traction lines can be pulled according to actual conditions to adjust the rotation amplitude of the second section 120, so as to avoid the second section 120 rotating at a larger or smaller amplitude to affect the connection between the air outlet 121 and the right lung lobe opening.

[0088] In some embodiments, a ventilation side hole 122 is provided on the second section 120 for cooperating with the air outlet 121 to ventilate the right lung;

[0089] A covering portion 5 is sleeved on the outer side of the second section 120 for covering the ventilation side hole 122. A traction portion 6 is connected to the covering portion 5. The traction portion 6 has a traction state. When the traction portion 6 is in the traction state, the traction portion 6 is connected to any air pipe 320 away from the traction line.

[0090] The human body's bronchi are divided into right bronchus and left bronchus. The left bronchus and the right bronchus supply air to the left lung and the right lung respectively. The right bronchus is further divided into upper lobe bronchus, middle lobe bronchus and lower lobe bronchus. Through the opening of the ventilation side hole 122, when the air outlet 121 is used to supply air to the right upper lobe through the upper lobe bronchus, the ventilation side hole 122 can cooperate with the air outlet 121 to supply air to the rest of the right lung. The covering part 5 can be used to cover the ventilation side hole 122, and through the traction of the traction part 6, when the ventilation side hole 122 is not needed to cooperate with the air outlet 121 to supply air to the rest of the right lung, the covering part 5 can be adjusted during the operation to cover the ventilation side hole 122 to avoid gas output through the ventilation side hole 122.

[0091] In summary, in the present invention, by setting up the ECG pacing assembly 400, artificial heart pacing can be completed while supplying air to the lungs. During the execution process, the ends of each pacing power line 430 away from the first electrode 410 are respectively connected to the positive and negative electrodes of the ECG pacemaker. In addition, each structure in the ECG pacing assembly 400 is arranged outside the double-chamber bronchial catheter, which can prevent the ECG pacing assembly 400 from affecting the double-chamber bronchial catheter from supplying air to the lungs, and can also prevent the double-chamber bronchial catheter from restricting the ECG pacing assembly 400 from completing the artificial heart pacing operation. In addition, by setting up the left bronchial catheter 1 and the right bronchial catheter 100, a double-chamber bronchial catheter can be formed to achieve independent air supply to the left lung and the right lung. At the same time, before supplying gas, the gas delivery component 300 can supply gas to the expansion component 200 so that the expansion component 200 expands in the trachea, thereby fixing the left bronchial catheter 1 and the right bronchial catheter 100 in the trachea, thereby preventing the left bronchial catheter 1 and the right bronchial catheter 100 from shaking during gas supply and affecting the treatment process.
