Description

Technical Field

[0001] The present invention relates to the technical field of bronchoscope use, in particular to a bronchoscope operation auxiliary device and a use method thereof. Background Art

[0002] The existing bronchoscope insertion technology is to directly apply lubricating liquid to the front end of the bronchoscope insertion part for lubrication, and then enter the trachea through the nasal cavity, epiglottis, and glottis. This method has many disadvantages, such as contaminating the bronchoscope body, bringing upper respiratory tract secretions into the lower respiratory tract, increasing the chance of infection and affecting the test results. Thicker bronchoscopes are prone to nose bleeding, especially for patients with relatively enlarged nasal conchae, who cannot even perform this operation through the nose, and the narrow nasopharyngeal passage also damages the bronchoscope itself. For physicians who are new to bronchoscopy, the process of inserting the bronchus through the nasal cavity is difficult to operate, requires a long time of learning, and is also very painful for patients. This is also an important reason why the development of local anesthesia bronchoscope technology is limited and patients are reluctant to accept local anesthesia bronchoscope examinations.

DETAILED DESCRIPTION

[0031] like Figures 1 to 9 As shown, the auxiliary device of the present invention mainly includes a shell 1, a fixing belt 2, a spray support pipe 3, a suction pipe 4 and an air intake pipe 5. The present invention is described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 , Figure 2 As shown, the shell 1 can be a telescopic structure, that is, it can be extended or retracted. After inflation, the lower part of the shell is hemispherical or cylindrical, and the upper part of the shell is cylindrical. At this time, the shell is made of rubber, and the shell is an inner and outer double-layer structure. An extension part 11 is provided on the side away from the shell at the small end of the shell. The extension part is also made of rubber, and the extension part is also an inner and outer double-layer structure. The extension part is a part of the shell. The shell and the extension part are interconnected, and an inflation cavity 12 is formed between the inner and outer layers of the shell. The entire shell is in a compressed state before inflation.

[0033] An air inlet pipe 5 is provided on the outer wall of the shell. The air inlet pipe is a hard plastic part and is connected to the inflation chamber 12. When in use, the extension part 11 is first extended through the nasal cavity to the epiglottis, and then the anesthetic drug is sprayed through the spray support tube 3. After a suitable time, the extension part is inserted into the airway. After entering the airway, the air inlet pipe is connected to a syringe with some air drawn out, and air is inflated into the inflation chamber to prop up the entire shell. The inner layer of the shell forms an operating chamber 13. When in use, the bronchoscope is inserted into the operating chamber.

[0034] like Figure 3 , Figure 4As shown, a circular opening 14 is provided on the top of the shell, and the opening is connected to the operation cavity. The opening is provided to facilitate the insertion of the bronchoscope into the operation cavity. After the bronchoscope enters the operation cavity, a small amount of gas can be released to avoid compressing the nasal cavity. The shell can also be a hard plastic part. In this case, the extension part and the shell are made of different materials, and the two are fixedly connected together. The inner and outer layers of the shell and the extension part together form an air-filled cavity.

[0035] like Figure 2 , Figure 5 As shown, the spray support tube is a hard plastic round tube. The first end of the spray support tube extends out of the shell. A first protrusion 31 is fixed to the first end of the spray support tube. The first protrusion is a cylindrical hollow structure. The inner cavity of the first protrusion is connected to the spray support tube. A first valve 32 made of rubber material is provided in the inner cavity of the first protrusion. A straight slit 7 is provided on the first valve. The setting of the first valve can block foreign matter, and the setting of the slit facilitates the insertion of the syringe outlet. The second end of the spray support tube extends into the inflation cavity, and the second end of the spray support tube extends out of the inflation cavity, as shown in FIG. Figure 7 As shown, a spray hole 33 is provided at the second end of the spray support pipe, and the spray holes are evenly arranged at the second end of the spray support pipe. The second end of the spray support pipe is in contact and sealed with the extension part to avoid air leakage of the inflation cavity.

[0036] For easy operation, the first end of the air inlet pipe extends into the inflation cavity, and the second end of the air inlet pipe is provided with a second protrusion 51, which is a cylindrical hollow plastic or rubber part. The inner cavity of the second protrusion is connected to the air inlet pipe, and a second valve 52 made of rubber material is provided on the inner side of the second protrusion. A straight slit 7 is provided on the second valve, and air can be inflated into the inflation pipe through the slit. The gas in the inflation cavity can also be extracted through the second protrusion and the air inlet pipe, so that the shell shrinks.

[0037] A pair of hanging ears 15 are fixed on the cylindrical outer wall of the shell, and a fixing belt 2 is provided on the hanging ears, and the fixing belt is an elastic belt. The fixing belt can be tied together with the hanging ears, or the fixing belt and the hanging ears can be sewn together by a thread. When in use, the fixing belt is put on the patient's ears to fix the shell.

[0038] like Figure 6 As shown, the straw 4 is a plastic tube, and an air bag 42 is fixed on the outer wall of the first end of the straw. The air bag is attached to the outer wall of the straw in the evacuated state, and the air bag is flattened to form an O shape. Figure 8As shown, an inflation tube 41 is connected to the airbag, and the inflation tube is fixed on the outer wall of the straw. When in use, the straw is inserted into the operating cavity. At this time, the bronchoscope can also be inserted into the operating cavity, and the position of the straw can be clearly observed through bronchoscope observation. Continue to insert the straw until the airbag extends out of the operating cavity, and then inflate the airbag through the inflation tube until the airbag expands and remains in an "O" shape after expansion. At this time, the straw cannot be pulled out of the operating cavity, and the straw is used to absorb liquid and block the irrigation fluid. The bronchoscope can also be inserted into the operating cavity, and the bronchoscope can be inserted into the inside of the airbag. While using the bronchoscope for operation, the straw can be used to absorb liquid and block the irrigation fluid. A third protrusion 6 is provided at the second end of the straw. Fig. 9 As shown, a third valve membrane 61 made of rubber material is provided in the third protrusion, and a straight-shaped slit is also provided on the third valve membrane. The structures and shapes of the first, second and third valve membranes are completely the same.

[0039] The method of using the present invention is described below:

[0040] (1) Insert the uninflated extension part through the nasal cavity into the epiglottis, and spray the medicine (such as anesthetic) through the spray support tube;

[0041] (2) After the epiglottis is anesthetized successfully, the extension part is passed through the epiglottis and then inserted into the airway, and the liquid medicine (such as anesthetic) is sprayed through the spray support tube;

[0042] (3) Inflate the air chamber of the shell through the air inlet pipe to prop up the shell; then insert a bronchoscope for examination and treatment;

[0043] (4) When the suction tube is needed as an auxiliary device, insert the suction tube into the operating cavity, insert the bronchoscope into the operating cavity, and then inflate the airbag through the inflation tube to make the airbag inflated; insert the bronchoscope into the inside of the airbag, and then observe and treat through the bronchoscope.
