Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, in particular to a disposable electronic bronchial endoscope. Background Art

[0002] Electronic bronchoscope is an important medical device. It converts images inside the trachea and bronchi into electrical signals through a micro-camera element at the front end, which are then processed by a computer to present high-definition images on a monitor. With its advantages of clear imaging, convenient operation, and the ability to store data, it is widely used in diagnostic scenarios such as diagnosis of unexplained respiratory symptoms, diagnosis and differentiation of lung diseases, and early screening for lung cancer, as well as in treatment areas such as foreign body removal, secretion clearance, local treatment, and stent placement. When using it, attention should be paid to precautions before, during, and after the examination to ensure the safety and effectiveness of the examination and treatment.

[0003] For patients with thick, difficult-to-cough sputum, lung infections with large amounts of secretions blocking the airway, or postoperative airway secretion accumulation, doctors can precisely locate the site of sputum accumulation under direct bronchoscope visualization and rapidly clear it through negative pressure suction, improving ventilation. This procedure not only directly alleviates airway obstruction but also allows for simultaneous observation of the airway mucosal condition. If necessary, combined with lavage therapy to dilute sputum, it is commonly used in settings such as severe pneumonia, respiratory failure, and postoperative airway management. It is an important clinical tool for clearing respiratory secretions. However, care must be taken to be gentle during the procedure to avoid damaging the mucosa, and the patient's breathing and bleeding should be observed postoperatively.

[0004] The existing technology has the following defects:

[0005] The electronic bronchoscope can complete the suction operation in the trachea through the built-in suction channel and introduce the sputum into the suction bottle. However, one suction may require 1-2 suction bottles. When replacing the second suction bottle, you need to remove the suction bottle in use first. Since sputum has a certain viscosity, sputum may remain at the interface between the suction bottle and the handle. The outflow and dripping of sputum will contaminate the surrounding environment or contaminate the hands of medical staff. When medical staff use their contaminated hands to pick up medical instruments, they will contaminate these medical instruments. Summary of the Invention

[0006] In view of the problem of sputum leakage and contamination in the existing technology, a disposable electronic bronchial endoscope is proposed.

[0007] The present application provides a disposable electronic bronchial endoscope, the purpose of which is to prevent sputum from leaking out.

[0008] The technical solution of the present invention is as follows: a disposable electronic bronchoscope, comprising a handle and a sputum suction bottle, an access port, a port and a connecting tube arranged on the outside of the handle, and a connecting bridge, wherein the connecting bridge specifically comprises a bridge body arranged between the handle and the sputum suction bottle, a communicating hole and a rotating groove provided inside the bridge body, a clamping block provided outside the communicating hole, a rotating ball provided inside the rotating groove, a connecting hole provided outside the rotating ball, a rotating column provided outside the rotating ball, and a rotating knob provided at an end of the rotating column away from the rotating ball;

[0010] The connecting tube is inserted into the communicating hole, one end of the communicating hole is connected to the handle, and the other end is connected to the suction bottle. The docking hole is docked with the pressure accumulator. The rotating ball is located in the middle of the communicating hole and cuts off the communicating hole. The connecting hole and the communicating hole are coaxially arranged. The docking hole vertically penetrates into the connecting hole. The docking hole is docked with the socket, and the pressure accumulator extends into the socket.

[0011] Furthermore, the pressure accumulator specifically includes a pressure accumulator chamber provided inside the console, a rotating shaft provided inside the pressure accumulator chamber, a middle groove provided on one end of the rotating shaft close to the rotating ball, a side groove provided on the outer side of the rotating shaft, and a side baffle provided on the inner wall of the pressure accumulator chamber;

[0012] Pressure storage chambers extend from both ends of the rotating shaft, and side baffles are wrapped around the outside of the rotating shaft. When the side grooves are rotated to fit into the side baffles, they will be shielded by the side baffles. When the side grooves are rotated to separate from the side baffles, they will be connected to the pressure storage chamber, and the middle groove extends into the socket.

[0013] Furthermore, the booster specifically includes a stamping cavity provided inside the console, an air intake hole provided between the inner wall of the stamping cavity and the outer wall of the console, a piston provided inside the stamping cavity, and a compression spring provided outside the piston;

[0014] The vent hole is connected to the pressure storage chamber and the punching chamber, and a one-way valve is installed between the vent hole and the air suction hole.

[0015] Furthermore, the cross-sectional area of ​​the stamping cavity is smaller than the cross-sectional area of ​​the pressure accumulation cavity.

[0016] Furthermore, four positioning marks are provided on the surface of the bridge body around the rotating knob.

[0017] Furthermore, a buckle is provided on the top of the sputum suction bottle, and a slot is provided on the surface of the bridge body, and the buckle is buckled in the slot.

[0018] Furthermore, a blocking component is provided inside the communicating hole at one end close to the sputum suction bottle, and the blocking component specifically includes a sliding cylinder provided at the opening of one end of the communicating hole close to the sputum suction bottle, a sliding groove provided inside the wall of the sliding cylinder, a fixed tube and a sliding tube provided outside the sliding cylinder, a tension spring provided inside the sliding groove, a flow hole provided at the end of the sliding cylinder away from the sputum suction bottle, and a central baffle provided inside the communicating hole;

[0019] The sliding tube extends into the sliding groove, one end of the tension spring is connected to the sliding tube, and the other end is connected to the inner wall of the sliding groove, and the central baffle is attached to the opening of the flow hole.

[0020] Furthermore, the blocking assembly further includes a storage groove provided on the inner wall of the communicating hole, a top baffle covering the opening of the storage groove, a crossbeam provided on the inner side of the top baffle, a push rod provided on the end of the sliding tube away from the suction bottle, and a push groove provided on a side of the push rod close to the crossbeam;

[0021] The storage tank is located between the blocking component and the cleaning component. An elastic connecting strip is arranged between the top baffle and the inner wall of the communicating hole. The opening direction of the top baffle is toward the suction bottle. The push rod is inclined, and the end close to the sliding cylinder is lower than the other end. The cross beam is clamped in the push groove.

[0022] Furthermore, the circulation hole and the central baffle are both located at the central axis of the communicating hole.

[0023] Beneficial effects of the present invention:

[0024] 1. By setting a connecting bridge, the suction bottle and the handle are kept at a certain distance to avoid the suction bottle affecting the operation of the handle during work. At the same time, using the suction bottle can improve the sealing of sputum during circulation, avoid leakage, and facilitate the control of sputum circulation.

[0025] By setting up a cleaning component, after suctioning is completed, the rotating ball is rotated to connect the docking hole with the jack, and then the high-pressure air in the pressure accumulator is released, and the air flow is filled into the connecting hole to push out the sputum in the connecting hole, ensuring the cleanliness of the connecting hole and preventing the sputum in the connecting hole from flowing out when the suction bottle is disassembled, causing pollution.

[0026] 2. By setting up a pressure accumulator, high-pressure air is accumulated in the pressure accumulator chamber, and the high-pressure air is discharged through the side groove by rotating the rotating shaft. This discharge method can reduce the impact of high-pressure air on the adjustment of the rotating shaft and make equipment control more convenient.

[0027] 3. By setting a blocking component, the sputum in the communicating hole pushes the sliding cylinder to open the flow hole, and the sputum flows into the sputum suction bottle. When the sputum suction is stopped, the flow hole is closed near the center baffle to prevent the sputum in the communicating hole from flowing out. At this time, a narrow space with only one side open is formed inside the sliding cylinder. In this way, the viscous sputum will be suppressed by the air in the sliding cylinder under the air pressure to prevent the sputum from leaking out. At the same time, after the sliding cylinder is reset, its opening is a certain distance away from the opening of the communicating hole, further reducing the possibility of sputum leakage.

[0028] 4. By setting up a storage groove, during the resetting process of the sliding cylinder, the movement of the push rod will push open the top baffle, and part of the sputum in the communicating hole and the sliding cylinder will flow into the storage groove, thereby reducing the amount of sputum in the communicating hole and the sliding cylinder, and the sputum in the sliding cylinder will move away from the opening of the sliding cylinder, further reducing the possibility of sputum leakage.

[0048] Specifically, a control rocker is also provided on the surface of the handle 1, the port 12 is connected to the external catheter, and an infusion port is provided on the side of the upper end of the suction bottle 3. The two ends of the bridge body 21 are respectively fitted with the handle 1 and the suction bottle 3, and the connecting tube 13 is inserted into the connecting hole 22. One end of the connecting hole 22 is connected to the handle 1, and the other end is connected to the suction bottle 3. The block 23 passes through the bridge body 21 and is clamped on the outside of the connecting tube 13. A buckle 31 is provided on the top of the suction bottle 3, and a card slot 32 is provided on the surface of the bridge body 21. The buckle 31 is buckled in the card slot 32. The connecting hole 26 passes through the rotating ball 25. The rotating ball 25 is located in the middle of the connecting hole 22 and cuts off the connecting hole 22. The connecting hole 26 connects the cut-off connecting hole 22. The connecting hole 26 is coaxially arranged with the connecting hole 22. The rotating ball 25 It is rotatably connected in the rotating groove 24, and the docking hole 414 vertically penetrates into the connecting hole 26. The docking hole 414 docks with the pressure accumulator, and the docking hole 414 docks with the socket 42. One end of the rotating column 27 is fixedly connected to the rotating ball 25, and the other end extends to the surface of the bridge body 21 and is engaged with the rotating knob 28. The rotating knob 28 is rotatably connected to the surface of the bridge body 21 through the rotating column 27, and the pressure accumulator extends into the socket 42; four positioning marks are set around the rotating knob 28 on the surface of the bridge body 21, which is convenient for control and positioning when adjusting the rotating knob 28. A fixing hole is opened on the inner wall of the mounting groove 41, and the outer wall of the console 43 protrudes outward and is engaged in the fixing hole. The bridge body 21 is divided into two at the central axis, and the two halves are fixed by bolts.

[0049] By setting the connecting bridge 2, the suction bottle 3 is kept at a certain distance from the handle 1, avoiding the suction bottle 3 from affecting the operation of the handle 1 during work. At the same time, using the suction bottle 3 can improve the sealing of sputum during circulation, avoid leakage, and facilitate the control of sputum circulation.

[0050] By setting up the cleaning component 4, after suctioning is completed, the rotating ball 25 is rotated to connect the docking hole 414 with the socket 42, and then the high-pressure air in the pressure accumulator is released, and the air flow is filled into the connecting hole 22, pushing out the sputum in the connecting hole 22, ensuring the cleanliness of the connecting hole 22 and preventing the sputum in the connecting hole 22 from flowing out when the suction bottle 3 is disassembled, causing pollution.

[0051] The pressure storage component specifically includes a pressure storage chamber 44 opened inside the console 43, a rotating shaft 410 arranged inside the pressure storage chamber 44, a middle groove 411 opened at one end of the rotating shaft 410 close to the rotating ball 25, a side groove 412 opened on the outside of the rotating shaft 410, and a side baffle 413 arranged on the inner wall of the pressure storage chamber 44.

[0052] Specifically, a sealed bearing is installed at the connection between the rotating shaft 410 and the console 43, and a pressure storage chamber 44 extends from both ends of the rotating shaft 410. The side baffle 413 is wrapped around the outside of the rotating shaft 410. When the side groove 412 is rotated to fit with the side baffle 413, it will be shielded by the side baffle 413. When the side groove 412 is rotated to separate from the side baffle 413, it will be connected to the pressure storage chamber 44, and the middle groove 411 extends into the socket 42.

[0053] By setting up a pressure accumulator, high-pressure air is accumulated in the pressure accumulator chamber 44, and the high-pressure air is discharged by rotating the rotating shaft 410 through the side groove 412. This discharge method can reduce the impact of high-pressure air on the adjustment of the rotating shaft 410, making equipment control more convenient.

[0054] The booster specifically includes a stamping chamber 45 opened inside the console 43, an air intake hole 47 opened between the inner wall of the stamping chamber 45 and the outer wall of the console 43, a piston 48 arranged inside the stamping chamber 45, and a compression spring 49 arranged outside the piston 48.

[0055] Specifically, the vent hole 46 connects the pressure storage chamber 44 and the stamping chamber 45, and a one-way valve is installed between the vent hole 46 and the air intake hole 47. The piston 48 extends to the surface of the console 43. The two ends of the compression spring 49 are respectively connected to the piston 48 and the console 43. The cross-sectional area of ​​the stamping chamber 45 is smaller than the cross-sectional area of ​​the pressure storage chamber 44, and the ratio of the two is not less than three, so that the force required to press the piston 48 can be reduced.

[0056] Example 2, reference Figures 1-14 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a blocking component 5 is provided at one end of the communicating hole 22 near the suction bottle 3, and the blocking component 5 specifically includes a sliding cylinder 51 provided at the opening of one end of the communicating hole 22 near the suction bottle 3, a sliding groove 52 opened inside the wall of the sliding cylinder 51, the sliding groove 52 divides the wall of the sliding cylinder 51 into an inner wall body and an outer wall body, wherein the length of the outer wall body is smaller than the inner wall body, a fixed tube 53 and a sliding tube 54 arranged on the outside of the sliding cylinder 51, a tension spring 55 arranged inside the sliding groove 52, a flow hole 56 opened at the end of the sliding cylinder 51 away from the suction bottle 3, and a central baffle 57 arranged inside the communicating hole 22.

[0057] Specifically, the opening of one end of the connecting hole 22 close to the suction bottle 3 is widened, and the blocking component 5 is installed at this widened position, the fixed tube 53 is clamped in the connecting hole 22, the sliding cylinder 51 is slidably installed in the connecting hole 22, the sliding tube 54 is slidably connected to the sliding groove 52, the sliding tube 54 extends into the sliding groove 52, one end of the tension spring 55 is connected to the sliding tube 54, and the other end is connected to the inner wall of the sliding groove 52, the center baffle 57 is attached to the opening of the circulation hole 56, the circulation hole 56 and the center baffle 57 are both located at the center axis of the connecting hole 22, and a damping ring is arranged between the sliding tube 54 and the sliding cylinder 51 to make the sliding cylinder 51 move slowly and uniformly when resetting.

[0058] By setting the blocking component 5, the sputum in the communicating hole 22 pushes the sliding cylinder 51 to open the circulation hole 56, and the sputum flows into the sputum suction bottle 3. When the sputum suction is stopped, the circulation hole 56 is closed near the center baffle 57 to prevent the sputum in the communicating hole 22 from flowing out. At this time, a narrow space with only one side open is formed inside the sliding cylinder 51. In this way, the viscous sputum will be suppressed by the air in the sliding cylinder 51 under the air pressure to prevent the sputum from leaking out. At the same time, after the sliding cylinder 51 is reset, its opening is a certain distance away from the opening of the communicating hole 22, further reducing the possibility of sputum leakage.

[0059] The blocking assembly 5 also includes a storage groove 58 opened on the inner wall of the communicating hole 22, a top baffle 59 covering the opening of the storage groove 58, a crossbeam 510 arranged on the inner side of the top baffle 59, a push rod 511 arranged on the end of the sliding cylinder 51 away from the suction bottle 3, and a push groove 512 opened on the side of the push rod 511 close to the crossbeam 510.

[0060] Specifically, the storage tank 58 is located between the blocking component 5 and the cleaning component 4, and an elastic connecting strip is arranged between the top baffle 59 and the inner wall of the connecting hole 22. The opening direction of the top baffle 59 is toward the suction bottle 3. The push rod 511 is inclined, and one end close to the sliding cylinder 51 is lower than the other end. The cross beam 510 is clamped in the push groove 512. The cross beam 510 is made of rubber and has a certain elasticity. The push rod 511 and the sliding cylinder 51 are connected by an elastic soft strip.

[0061] By providing the storage groove 58, during the resetting process of the sliding cylinder 51, the movement of the push rod 511 will push open the top baffle 59, and part of the sputum in the communicating hole 22 and the sliding cylinder 51 will flow into the storage groove 58, thereby reducing the amount of sputum in the communicating hole 22 and the sliding cylinder 51, and the sputum in the sliding cylinder 51 will move away from the opening of the sliding cylinder 51, further reducing the possibility of sputum leakage.

[0062] The remaining structures are the same as those of Example 1.

[0063] Based on Examples 1-2, the working principle of the disposable electronic bronchial endoscope of the present invention is as follows:

[0064] Insert the catheter into the airway from the patient's mouth and nose, find the lesion, then start the handle 1 and turn the rotating knob 28. The rotating knob 28 drives the rotating ball 25 to rotate through the rotating column 27, so that the connecting hole 26 is parallel to the connecting hole 22, and the docking hole 414 is misaligned with the insertion hole 42. In this way, the sputum in the airway flows out along the catheter, and then the sputum enters the connecting hole 22 through the connecting tube 13, and then flows through the connecting hole 26 close to the blocking component 5. The flowing sputum pushes the sliding cylinder 51, and the sliding cylinder 51 slides in the connecting hole 22, partially extending out of the connecting hole 22 into the sputum suction bottle 3. At this time, the flow hole 56 is also separated from the center baffle 57, and the sputum flows from the flow hole 56 into the sliding cylinder 51, and finally flows into the sputum suction bottle 3.

[0065] When the handle 51 is closed, the sputum in the communicating hole 22 and the sliding cylinder 51 stops flowing, and the sliding cylinder 51 loses the thrust and is reset under the action of the tension spring 55, and the sliding cylinder 51 slides in the communicating hole 22 in the direction away from the sputum suction bottle 3 and moves accordingly, and the pushing groove 512 is stuck in the outer side of the cross beam 510. In this way, when the push rod 511 moves, the cross beam 510 is pushed, which exerts an upward turning force on the top baffle 59. After the top baffle 59 is opened upward, the sputum in the communicating hole 22 and the sliding cylinder 51 will flow into the storage groove 58, reducing the sputum stock in the communicating hole 22 and the sliding cylinder 51. At the same time, after the sliding cylinder 51 is fully reset, the flow hole 56 is closed, and the sliding cylinder 51 and the communicating hole 22 are separated. The air pressure will seal the sputum in the sliding cylinder 51. At this time, the sputum stock in the sliding cylinder 51 is less than the internal volume of the sliding cylinder 51, and the buckle 31 is pressed to remove the sputum suction bottle 3 from the bridge body 21.

[0066] After completing all the suction work, rotate the rotating ball 25 to connect the connecting hole 22 and the socket 42 through the connecting hole 26 and the docking hole 414, press the piston 48, and the piston 48 pushes the air in the stamping chamber 45 into the pressure storage chamber 44 through the vent 46. Then the compression spring 49 pushes the piston 48 to reset, and the outside air flows into the stamping chamber 45 through the suction hole 47. This is repeated to continuously inflate and pressurize the pressure storage chamber 44, and then turn to the rotating shaft 410 to make the side groove 412 and the side baffle 413 misaligned and connected to the pressure storage chamber 44. The high-pressure airflow in the pressure storage chamber 44 enters the connecting hole 22, which will discharge the sputum remaining in the connecting hole 22. After use, the suction bottle 3 and the connecting bridge 2 are discarded into the waste disposal bucket.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
