Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a bronchoscope. Background Technology
[0002] A bronchoscope is a medical device used to examine the inside of the respiratory tract (mainly the trachea and bronchi). It is a long, thin, flexible tube with a light source and camera at the tip. It can be inserted through the mouth or nose to reach the patient's trachea and bronchi, allowing doctors to directly observe these areas.
[0003] Currently, when using bronchoscopy to examine patients, doctors need to hold the main unit of the bronchoscope with one hand and insert the examination tube into the patient's airway with the other. However, in actual examinations, because the trachea and bronchi are narrow cavities in the human respiratory system, and patients with respiratory diseases may have a large amount of sputum and other secretions blocking their airways, inserting the bronchoscope further reduces the space available for airway passage, which may cause breathing difficulties, make the patient feel extremely uncomfortable, and increase their suffering. Furthermore, sputum in the airway can also obstruct the clarity of the bronchoscope's field of vision, making it difficult for doctors to observe lesions and thus affecting the diagnosis of the patient's condition.

[0029] Example:
[0030] Reference Figures 1-6 This utility model provides a bronchoscope, including a housing 1 with an examination tube 2, a monitoring component 3, and a main unit 4 installed thereon. The examination tube 2 is connected to the housing 1, the monitoring component 3 is installed at the end of the examination tube 2, and the main unit 4 is fixedly installed on the top of the housing 1. The bronchoscope also includes a housing 5, which is fixedly installed inside the housing 1. A piston 8 is installed inside the housing 5, and a driving part for driving the piston 8 to slide inside the housing 5 is provided on the housing 5. A suction tube 6 and an oxygen supply tube 7 are both connected to the housing 5. The suction tube 6 is provided with a sputum clearing part, and the oxygen supply tube 7 is provided with an oxygen supply part.
[0031] Specifically, during use, the combined operation of the drive unit and oxygen supply unit helps patients breathe air more smoothly, greatly reducing discomfort during the examination process and alleviating their pain. This allows patients to better cooperate with doctors during the examination. The combined operation of the drive unit and the sputum-clearing unit can clear sputum and other secretions from the patient's airway during the examination, preventing sputum and other secretions from blocking the airway and obstructing the clarity of the endoscope's field of vision. This allows doctors to observe the lesion site, thereby improving the accuracy of doctors' diagnosis of the patient's condition and helping patients breathe air more smoothly.
[0032] The drive unit of this bronchoscope includes a motor 82 fixedly mounted on a housing 5. The motor 82 is electrically connected to the main unit 4. A reciprocating lead screw 81 is rotatably connected inside the housing 5. The output end of the motor 82 and the surface of the reciprocating lead screw 81 are both fixedly connected to meshing bevel gears 83. A threaded sleeve 84 is slidably mounted inside the housing 5. The threaded sleeve 84 is threadedly connected to the surface of the reciprocating lead screw 81. A piston 8 is fixedly connected to the threaded sleeve 84.
[0033] Specifically, during use, by starting the motor 82, the output end of the motor 82 drives the bevel gear 83 and the reciprocating screw 81 to rotate. Under the action of the thread, the screw sleeve 84 moves longitudinally back and forth along the guide plate 85, and drives the piston 8 to slide longitudinally back and forth in the housing 5, which can clear sputum or assist the patient in breathing air.
[0034] A support plate 51 is fixedly connected inside the outer shell 1, and the shell 5 is fixedly connected to the support plate 51.
[0035] Specifically, the support plate 51 can support and fix the shell 5 to improve the stability of the shell 5.
[0036] A guide plate 85 is fixedly connected inside the housing 5, and a threaded sleeve 84 is longitudinally slidably connected to the guide plate 85.
[0037] Specifically, the guide plate 85 can guide the screw sleeve 84 and prevent it from rotating with the reciprocating screw 81.
[0038] The aforementioned sputum-clearing unit includes a negative pressure tube 61 connected to the suction tube 6. The end of the negative pressure tube 61 away from the suction tube 6 extends to the outside of the examination tube 2. A ventilation tube 62 is connected to the housing 5. The end of the ventilation tube 62 away from the housing 5 extends to the outside of the outer shell 1. The bottom of the housing 5 is connected to a sputum-expelling tube 63. The end of the sputum-expelling tube 63 away from the housing 5 extends to the outside of the outer shell 1 and is connected to a collection device. A first electric valve 64 is fixedly installed on the suction tube 6, and a second electric valve 65 is fixedly installed on the sputum-expelling tube 63. Both the first electric valve 64 and the second electric valve 65 are electrically connected to the main unit 4. A one-way valve is provided inside both the suction tube 6 and the sputum-expelling tube 63.
[0039] Specifically, during use, the first electric valve 64 and the second electric valve 65 are opened first, and the piston 8 reciprocates within the housing 5. When the piston 8 moves upward, sputum and other secretions in the patient's airway are drawn into the housing 5 through the negative pressure tube 61 and the suction tube 6. When the piston 8 moves downward, sputum and other secretions are discharged into the collection cup 91 through the discharge tube 63. This allows for the clearing of sputum and other secretions in the patient's airway during the examination, preventing airway blockage and obstruction of the clarity of the endoscope's field of vision. This facilitates the doctor's observation of the lesion site, thereby improving the accuracy of the doctor's diagnosis of the patient's condition and helping the patient breathe more smoothly.
[0040] Furthermore, the one-way valves inside the suction tube 6 and the discharge tube 63 prevent the backflow of sputum and other secretions from the suction housing 5 back into the patient's airway, ensuring that the sputum in the suction housing 5 can only be discharged into the collection cup 91 through the discharge tube 63.
[0041] The aforementioned oxygen supply unit includes an air supply pipe 71 connected to the oxygen supply pipe 7. The end of the air supply pipe 71 away from the oxygen supply pipe 7 extends to the outside of the inspection pipe 2. The bottom of the housing 5 is connected to an air inlet pipe 72. The end of the air inlet pipe 72 away from the housing 5 extends to the outside of the outer casing 1. A third electric valve 73 is fixedly installed on the oxygen supply pipe 7, and a fourth electric valve 74 is fixedly installed on the air inlet pipe 72. Both the third electric valve 73 and the fourth electric valve 74 are electrically connected to the main unit 4. A one-way valve is provided in both the oxygen supply pipe 7 and the air inlet pipe 72.
[0042] Specifically, during use, the third electric valve 73 and the fourth electric valve 74 are first opened, and the piston 8 reciprocates within the housing 5. When the piston 8 moves upward, outside air is drawn into the housing 5 through the air inlet pipe 72. When the piston 8 moves downward, air is delivered to the patient's airway through the oxygen supply pipe 7 and the air delivery pipe 71. This helps the patient breathe more smoothly, greatly reducing discomfort during the examination and alleviating the patient's pain, thus facilitating better cooperation with the doctor during the examination.
[0043] Furthermore, through the one-way valves inside the oxygen supply pipe 7 and the air intake pipe 72, outside air can only enter the housing 5 through the air intake pipe 72, while the inhaled air can only be discharged into the collection cup 91 through the oxygen supply pipe 7 and the air delivery pipe 71.
[0044] The aforementioned collection device includes a top cover 9 fixedly connected to the sputum drainage tube 63, the top cover 9 and the sputum drainage tube 63 are interconnected, a collection cup 91 is threadedly connected to the top cover 9, and a one-way valve is provided on the top cover 9.
[0045] Specifically, the combined use of the top cover 9 and the collection cup 91 facilitates the centralized collection of sputum and other secretions, making it easier to process the collected sputum in a unified manner.
[0046] Furthermore, the one-way valve on the top cover 9 allows the gas entering the collection cup 91 to be discharged to the outside in one direction during the sputum collection process.
[0047] The collection cup 91 is provided with multiple scale lines 92, and the multiple scale lines 92 are arranged longitudinally on the surface of the collection cup 91.
[0048] Specifically, the setting of the scale line 92 makes it easy to observe the storage capacity of secretions such as sputum in the collection cup 91.
[0049] The outer shell 1 is provided with a plurality of anti-slip patterns 10, and the plurality of anti-slip patterns 10 are arranged longitudinally on the surface of the outer shell 1. The number of anti-slip patterns 10 is preferably 20, and they are symmetrically arranged on both sides of the surface of the outer shell 1.
[0050] Specifically, by setting the anti-slip texture 10, the friction of the outer shell 1 surface can be increased, so that doctors can grip the outer shell 1 and thus play an anti-slip role.
[0051] The aforementioned monitoring component 3 includes a camera 31 fixedly installed at the bottom of the inspection tube 2, and a lighting lamp 32 fixedly installed on the camera 31. Both the camera 31 and the lighting lamp 32 are electrically connected to the host 4.
[0052] Specifically, the camera 31 and the lighting 32 enable doctors to easily photograph and observe the condition inside the patient's airway.
[0053] Working principle: During the use of this bronchoscope, the doctor first holds the outer shell 1 and inserts the examination end of the examination tube 2 into the patient's airway, and then examines the patient's airway through the cooperation of the main unit 4, camera 31 and lighting 32.
[0054] Furthermore, during the examination, by starting the motor 82, the output end of the motor 82 drives the bevel gear 83 and the reciprocating screw 81 to rotate. Under the action of the thread, the screw sleeve 84 moves longitudinally along the guide plate 85 and drives the piston 8 to slide longitudinally back and forth in the housing 5, which can clear sputum or assist the patient in breathing air.
[0055] In the assisted breathing state, by opening the third electric valve 73 and the fourth electric valve 74, when the piston 8 moves upward, outside air is drawn into the housing 5 through the air inlet pipe 72. When the piston 8 moves downward, air is delivered to the patient's airway through the oxygen supply pipe 7 and the air delivery pipe 71. This can help the patient breathe air more smoothly, greatly reduce the patient's discomfort during the examination process, thereby reducing the patient's pain and helping the patient to better cooperate with the doctor during the examination.
[0056] In addition, during the cleaning process, by opening the first electric valve 64 and the second electric valve 65, when the piston 8 moves upward, sputum and other secretions in the patient's airway are drawn into the housing 5 through the negative pressure tube 61 and the suction tube 6. When the piston 8 moves downward, the sputum and other secretions are discharged into the collection cup 91 through the discharge tube 63. This allows for the clearing of sputum and other secretions in the patient's airway during the examination, preventing sputum and other secretions from blocking the airway and hindering the clarity of the endoscope's field of vision. This makes it easier for doctors to observe the lesion site, thereby improving the accuracy of doctors' diagnosis of the patient's condition and helping patients breathe more smoothly.
[0057] It should be noted that, unless otherwise specified, electric valves are closed by default during use.
[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
