Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a movable multi-balloon hemostatic device. Background Art

[0002] Massive hemorrhage in the airway is a serious and urgent condition that requires immediate treatment to prevent asphyxia and other serious complications. Usually, under a bronchoscope, a catheter with a balloon can be placed at the bleeding site in the airway, and then the balloon is inflated and pressurized to perform compression hemostasis. This method is also known as endobronchial balloon tamponade.

[0003] One of the most effective methods for treating massive airway hemorrhage currently is to use a hemostatic balloon catheter. The hemostatic balloon catheter is usually a slender hollow tube with an expandable balloon at its front end and a balloon dilator pump connected to its rear end. When performing a fiberoptic bronchoscopy on a patient, if massive hemorrhage occurs, the hemostatic balloon catheter cannot be directly inserted into the airway. Usually, a guide wire is first inserted into the catheter of the fiberoptic bronchoscope, and the front end of the guide wire is advanced along the fiberoptic bronchoscope catheter to the bleeding position. Then, the fiberoptic bronchoscope is withdrawn, and the hemostatic balloon catheter is sleeved over the guide wire so that the front end of the hemostatic balloon catheter reaches the bleeding position where the front end of the guide wire is located. Then, the guide wire is withdrawn, and the balloon dilator pump is activated to expand the balloon at the front end of the hemostatic balloon catheter to block the airway and perform hemostasis. During this hemostatic operation process, when the hemostatic balloon catheter is introduced by the guide wire, or when the fiberoptic bronchoscope is withdrawn from the guide wire, it is easy for the front end of the catheter to be misaligned with the front end of the guide wire, or for the guide wire to displace, resulting in the instability of the hemostatic balloon catheter in the airway and the inability to accurately align with the bleeding point, leading to hemostasis failure.

[0004] Although there are various types of hemostatic balloon catheters commonly used currently, only one balloon is provided on the catheter. When encountering a bleeding point in the airway, it can only compress the airway wall at the bleeding point for hemostasis, and cannot achieve compression of multiple local areas in the airway to more precisely control airway bleeding. In case of an emergency with multiple bleeding points in the main airway and bronchial airways, hemostatic operations cannot be performed simultaneously.

[0005] Moreover, in the prior art, the balloon at the front end of the endotracheal tube is usually circular after inflation, and the contact area with the tissues in the airway is limited. When the bleeding point is large, even after the balloon is inflated, the compression surface on the tissues in the airway is insufficient, and hemostasis cannot be performed quickly and effectively.

[0006] Therefore, it is very necessary to design a movable multi-balloon hemostatic device. Summary of the Utility Model

[0007] Aiming at the deficiencies of the above-mentioned prior art, the utility model aims to provide a movable multi-airbag hemostatic device, which is provided with a first hemostatic airbag, a second hemostatic airbag and a fixing airbag, and the structure is optimized. Through the design of multiple airbags, the utility model can independently adjust the inflation pressure of each airbag, increase the compression area with the airway wall, and keep the main tube stable in the airway. For a bleeding point in the airway, it can exert pressure on multiple different parts of the airway, and more precisely control airway bleeding. And by setting the first hemostatic airbag and the fixing airbag, the fixing airbag can be used to compress and stop bleeding at the bleeding point of the bronchus, and at the same time, the position of the first hemostatic airbag can be flexibly pulled to align with other bleeding points in the main airway for rapid and effective hemostasis.

[0032] To elaborate on the technical content, structural features, achieved objectives and beneficial effects of the present utility model in detail, the following will be described in detail with reference to the drawings of the specification.

[0033] A movable multi-airbag hemostasis device of the present utility model, asFigures 1 to 5 As shown in the figure, it includes a main pipe 1, a first hemostatic component, a second hemostatic component, a main pipe fixing component and a ventilation pipe 11. The first hemostatic component, the second hemostatic component and the main pipe fixing component are sequentially arranged on the outer wall of the main pipe 1 from top to bottom.

[0034] The first hemostatic component includes a first hemostatic airbag 21, a push rod 26, a support rod 27, a fixed snap ring 24, a sliding snap ring 25, a push airbag 23 and a push airbag inflation pipe 22.

[0035] The first hemostatic airbag 21 is set as a cylindrical structure and is a movable hemostatic airbag. The axial length of the first hemostatic airbag 21 is greater than 3 cm, which can increase the compression area of the airway wall and evenly apply pressure to the airway wall. The first hemostatic airbag 21 is a double-layer inflated airbag, and an appropriate amount of gas is filled in the first hemostatic airbag 21. A support sleeve 28 is arranged at the center of the first hemostatic airbag 21, and the support sleeve 28 is slidably connected to the main pipe 1. Specifically, the inner diameter of the support sleeve 28 is greater than the outer diameter of the main pipe 1.

[0036] Multiple support rods 27 are axially and evenly distributed on the inner wall of the first hemostatic airbag 21, and the support rods 27 are located between the first hemostatic airbag 21 and the support sleeve 28. Both ends of the support rod 27 are rotatably connected to the fixed snap ring 24 and the sliding snap ring 25 through the push rod 26 respectively. In the embodiment of the present invention, suspension holes 29 are arranged at both ends of the support rod 27, and suspension lugs 30 are arranged on both the fixed snap ring 24 and the sliding snap ring 25. The number of suspension lugs 30 arranged on the fixed snap ring 24 and the sliding snap ring 25 is the same as the number of support rods 27 and corresponds to the position of the support rods 27 one by one. The upper end of the push rod 26 passes through the suspension hole 29, and the lower end of the push rod 26 is connected at the suspension lug 30, and the push rod 26 can perform a flipping motion relative to the fixed snap ring 24 and the sliding snap ring 25.

[0037] The angle range of the outward flipping of the push rod 26 is set to 0 - 90 degrees, that is, when the push airbag 23 is inflated, according to the pressure magnitude, the push rod 26 reciprocates within the angle range between the vertical state and the horizontal state. When not inflated, the initial state of the push rod 26 is the vertical state, that is, 0 degrees, and the first hemostatic airbag 21 is in a fully contracted state. When the gas filled in the push airbag 23 increases, the push airbag 23 expands and pushes the sliding snap ring 25 upward. The push rod 26 is forced to flip outward and gradually reaches the horizontal state, that is, when it is 90 degrees, the first hemostatic airbag 21 is fully extended and tightened by the support rod 27. When the push rod is in the horizontal state, the compression force of the first hemostatic airbag 21 on the airway wall is the largest.

[0038] The flipping angle of the push rod 26 is adjusted according to the air pressure charged into the pushing airbag 23. Specifically, when the device enters a narrower airway, less gas is charged into the pushing airbag 23, the air pressure becomes lower, and the flipping angle of the push rod 26 outward will stay at different angles such as 75 degrees, 45 degrees, 30 degrees, etc., to adjust the stretching degree of the first hemostatic airbag 21 according to the width of the airway and meet the hemostasis requirements of different airways.

[0039] The first hemostatic airbag 21 is located between the fixed snap ring 24 and the sliding snap ring 25. The fixed snap ring 24 and the support sleeve 28 are of an integral structure and are located above the first hemostatic airbag 21. The sliding snap ring 25 is slidably connected to the support sleeve 28 below the first hemostatic airbag 21. The inner wall of the pushing airbag 23 and the support sleeve 28 can be fixedly connected by an adhesive method. The upper surface of the pushing airbag 23 is connected to the sliding snap ring 25. The pushing airbag inflating tube 22 is arranged between the support sleeve 28 and the first hemostatic airbag 21. The upper part of the pushing airbag inflating tube 22 is connected to an air pump outside the airway. The middle part of the pushing airbag inflating tube 22 is clamped on the fixed snap ring 24. The lower end of the pushing airbag inflating tube 22 is communicated with the pushing airbag 23 to inflate the pushing airbag 23.

[0040] The second hemostatic component includes a second hemostatic airbag 3 and a second hemostatic airbag inflating tube 13. The second hemostatic airbag 3 is a fixed hemostatic airbag and its inner wall and the main tube 1 can be fixedly connected by an adhesive method. The outer wall of the second hemostatic airbag 3 after inflation presses against the airway wall at the target point in the main airway. The target point mentioned in the present utility model is the airway bleeding point, and the airway bleeding point contacted by the second hemostatic airbag 3 is the bleeding point at the lowermost end of the main airway. The second hemostatic airbag inflating tube 13 is arranged in the main tube 1 and its lower end passes through the side wall of the main tube 1 and is communicated with the second hemostatic airbag 3 to inflate the second hemostatic airbag 3.

[0041] The main tube fixing component includes a fixing airbag 2 and a fixing airbag inflating tube 12. The inner wall of the fixing airbag 2 and the main tube 1 can be fixedly connected by an adhesive method. The fixing airbag 2 is fixed in the branch airway connected below the main airway after inflation. The fixing airbag inflating tube 12 is arranged in the main tube 1 and its lower end passes through the side wall of the main tube 1 and is communicated with the fixing airbag 2 to inflate the fixing airbag 2. The position where the fixing airbag 2 is fixed can be either at the bleeding point in the branch airway or on the airway wall without bleeding.

[0042] In the embodiment of the present utility model, the insertion end of the main tube 1, that is, the front end of the main tube, is provided with a bending portion 4. The fixed airbag 2 is arranged below the bending portion and extends into the branch airway, and the second hemostatic airbag 3 is arranged above the bending portion and corresponds to the bleeding point at the lowest end of the main airway. The length of the bending portion 4 between the fixed airbag 2 and the second hemostatic airbag 3 is set to 4 - 5 cm, which can better match the distance between the branch airway opening and the main airway. When the fixed airbag 2 enters the left or right branch airway, it can also ensure that the second hemostatic airbag 3 remains in the main airway.

[0043] The fixed airbag 2 is arranged in the branch airway for fixation, so that the main tube 1 remains stable in the main airway. When compressing and stopping bleeding for other bleeding points in the main airway and the branch airway, such as when there is a bleeding point in the branch airway, the bleeding can be stopped by compressing with the fixed airbag 2. If there is no bleeding point in the branch airway, the fixed airbag 2 only plays a fixing role. When other bleeding points appear in the main airway and the first hemostatic airbag 21 moves in the main airway by pulling the pushing airbag inflatable tube 22, due to the fixation of the fixed airbag 2, it will not affect the hemostatic effect of the second hemostatic airbag 3 on the first bleeding point.

[0044] The angle of deflection of the bending portion 4 relative to the vertical direction is 10 - 15 degrees, which can not only make the main tube easy to insert into the branch airway, but also make the ventilation tube 11 and the fixed airbag inflatable tube 12 not easily fold when extending along the guiding action of the main tube 1 to the branch airway, and will not hinder the air flow.

[0045] The ventilation tube 11 is arranged in the main tube 1. The upper end of the ventilation tube 11 is fixed outside the airway, and the lower end of the ventilation tube 11 extends into the branch airway to keep the airway unobstructed during the hemostasis process. In the embodiment of the present utility model, the inner diameter of the main tube 1 is larger than the sum of the outer diameters of the ventilation tube 11, the second hemostatic airbag inflatable tube 13 and the fixed airbag inflatable tube 12, so that the inflatable tubes and the ventilation tube can pass smoothly in the main tube.

[0046] The first hemostatic airbag 21, the second hemostatic airbag 3 and the fixed airbag 2 are all in an uninflated state before entering the airway and can all adjust the air pressure through an air pump. The first hemostatic airbag 21 is set in a cylindrical structure, and the second hemostatic airbag 3 and the fixed airbag 2 are both set in an oval structure, increasing the contact area with the tissues in the airway and achieving a better hemostatic effect by compression.

[0047] One-way valves (not shown in the figure) are arranged at the joints of the upper ends of the pushing airbag inflatable tube 22, the second hemostatic airbag inflatable tube 13 and the fixed airbag inflatable tube 12 with the air pump. When it is necessary to replace the air pump, it can prevent gas from leaking back, resulting in unstable air pressure in each airbag and affecting the hemostatic effect.

[0048] The following further describes the specific embodiments of the present utility model:

[0049] A movable multi-airbag hemostatic device of the present utility model is as follows Figures 1-5 shown, and its specific implementation process is as follows:

[0050] The fixing airbag 2 and the second hemostatic airbag 3 are fixed below and above the bending part according to a preset spacing. Through holes are provided on the side walls of the main pipes corresponding to the fixing airbag 2 and the second hemostatic airbag 3. The fixing airbag inflating pipe 12 is inserted into the main pipe 1, and the lower end of the fixing airbag inflating pipe 12 communicates with the fixing airbag 2 from the through hole. The second hemostatic airbag inflating pipe 13 is inserted into the main pipe 1, and the lower end of the second hemostatic airbag inflating pipe 13 communicates with the second hemostatic airbag 3 from the through hole.

[0051] Support rods 27 are provided on the inner wall of the first hemostatic airbag 21. The first hemostatic airbag 21 is sleeved on the support sleeve 28. The upper end of the support rod 27 is rotatably connected to the fixed collar 24 through a push rod 26. The lower end of the support rod 27 is rotatably connected to the sliding collar 25 through a push rod 26. The sliding collar 25 is slidably sleeved on the support sleeve 28. The pushing airbag 23 is fixedly connected below the sliding collar 25 with the support sleeve 28. The pushing airbag inflating pipe 22 is inserted between the support sleeve 28 and the first hemostatic airbag 21. The lower end of the pushing airbag inflating pipe 22 communicates with the pushing airbag 23. The middle part of the pushing airbag inflating pipe 22 is clamped on the fixed collar 24. The upper end of the pushing airbag inflating pipe 22 is connected to an air pump outside the air duct.

[0052] The support sleeve 28 is sleeved on the main pipe 1 and is located above the second hemostatic airbag 3.

[0053] This device is inserted into the air duct in the way of the prior art, which will not be elaborated here. When there are two bleeding points in the main air duct, the fixing airbag 2 extends into the branch air duct and is fixed after passing through the bleeding point (target point) at the lowest end of the main air duct. Just the second hemostatic airbag 3 corresponds to the bleeding point. After the fixing airbag 2 is inflated, it presses against the airway wall, so that the main pipe 1 can be fixed. The outer wall of the second hemostatic airbag 3 after inflation presses against the airway wall at the bleeding point. Then, the pushing airbag inflating pipe 22 is pulled, so that the first hemostatic component slides upward along the main pipe 1 to other bleeding points in the main air duct. The pushing airbag inflating pipe 22 is fixed outside the air duct, and the pushing airbag 23 is inflated to make it expand. The sliding collar 25 rises, and the push rod 26 turns outward to make the first hemostatic airbag 21 stretch. The outer wall of the first hemostatic airbag 21 presses against the airway wall at the bleeding point, realizing effective and rapid hemostasis of the two bleeding points at the same time. The ventilation pipe 11 extends from the main pipe 1 into the branch air duct, which can keep the air flow unobstructed during the compression hemostasis process. One-way valves are provided at the connections between the upper parts of the fixing airbag inflating pipe 12, the second hemostatic airbag inflating pipe 13 and the pushing airbag inflating pipe 11 and the air pump. When it is necessary to replace the air pump, it can prevent the gas from leaking back and causing unstable pressure, affecting the hemostasis effect.

[0054] When there is only one bleeding point in the main airway, only the second hemostatic balloon 3 or the first hemostatic balloon 21 is used for hemostasis, and the fixing balloon 2 is used for fixation. The unprepared balloon can also locally compress the airway wall. Compared with the situation where only one balloon compresses the bleeding point, multiple balloons compressing multiple local areas can more precisely inhibit bleeding and avoid damage to the airway wall tissue caused by excessive compression time or pressure at one place.

[0055] When there is no bleeding point in the bronchus, the fixing balloon 2 only plays a fixing role. When there are bleeding points in both the bronchus and the main airway, the fixing balloon 2, the second hemostatic balloon 3 and the first hemostatic balloon 21 are all used for compressive hemostasis to stop bleeding simultaneously and improve the hemostatic effect. Moreover, the axial lengths of the fixing balloon 2 and the second hemostatic balloon 3 are both greater than 2 cm, which can increase the compression area when the balloon expands, can not only stop bleeding effectively and quickly, but also cause no harm to the airway tissue.

[0056] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
