Abstract
Description
Technical Field
[0001] This utility model belongs to the field of surgical instrument accessories, specifically relating to an auxiliary device for bronchoscopy based on a respiratory anesthesia tubing. Background Technology
[0002] A bronchoscope mainly consists of a control handle and a fiber optic bundle. When performing a bronchoscopy, the bronchoscope fiber optic bundle needs to be inserted into the patient's bronchus after the patient has been given general anesthesia. Under anesthesia, a laryngeal mask airway is needed to establish a respiratory support channel for the patient. Specifically, a three-way laryngeal mask airway inlet is connected to the laryngeal mask airway inlet. One of the remaining two ports of the laryngeal mask airway inlet is used to connect to the anesthesia machine, and the other is the bronchoscope insertion port for inserting the bronchoscope into the laryngeal mask airway and then into the patient's bronchus. Because bronchoscopy requires repeatedly inserting and withdrawing the bronchoscope fiber bundle to switch the examination angle and observe different parts of the body, the bronchoscope fiber bundle and the laryngeal mask airway (LMA) can not be fixed together. However, it is also necessary to prevent air from entering through the bronchoscope insertion port on the LMA during bronchoscopy. Based on these requirements, in order to achieve a flexible sealing effect, medical staff usually use rubber gloves to cover the bronchoscope insertion port on the LMA. However, this method increases the difficulty of bronchoscopy and the sealing effect is unstable. Therefore, this invention provides an auxiliary device for bronchoscopy based on a respiratory anesthesia tubing. Utility Model Content
[0003] The purpose of this invention is to provide an auxiliary device for bronchoscopy based on a respiratory anesthesia tubing to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] This utility model provides an auxiliary device for bronchoscopy based on a respiratory anesthesia tubing, including a telescopic tube and an outlet and an inlet tube at both ends of the telescopic tube. The outlet tube has a locking tube at its outlet for docking with the bronchoscope insertion port of the laryngeal mask airway. The inlet tube has a wrapping balloon at its inlet for wrapping the bronchoscope fiber bundle from the outside. An air inlet tube is connected to the wrapping balloon. A sealing membrane is provided between the wrapping balloon and the inlet tube.
[0006] As a further optimization of this utility model, the wrapping airbag has a ring structure and includes an elastic part and a rigid part, with the elastic part located on the arc surface inside the wrapping airbag.
[0007] As a further optimization of this utility model, an air reservoir for inflating the airbag is provided on the outside of the airbag, and the air inlet pipe is connected to the air reservoir.
[0008] As a further optimization of this utility model, the air reservoir has a missing ring structure and is sleeved on the outside of the air bag, and the air inlet pipe is located at one end of the missing ring structure. The outside of the air reservoir is provided with an adhesive layer and a shielding film is provided on the outside of the adhesive layer.
[0009] As a further optimization of this utility model, the passage of the air intake pipe is opened by the airflow when the airbag is inflated using the air storage bag.
[0010] As a further optimization of this utility model, a sealing element is provided on the outer side of the card tube.
[0011] The beneficial effects of this utility model are as follows:
[0012] This bronchoscopy auxiliary device for respiratory anesthesia tubing, through the cooperation of a telescopic rod, a wrapping cuff, and a sealing membrane, achieves the effect of sealing the bronchoscope insertion port without affecting the free flow of the bronchoscope fiber bundle. This avoids the problem of air entering the patient's body through the insertion port during bronchoscopy. Specifically, the telescopic rod can adapt to the bronchoscope's movement, and the sealing membrane allows the wrapping cuff to move slightly with the movement of the bronchoscope. Therefore, the wrapping cuff can always move synchronously with the wrapped part of the bronchoscope, remaining relatively stationary. Compared with the method of sealing the bronchoscope with a fixed elastic element, this further reduces the probability of air leakage due to loosening of the sealed part of the bronchoscope, achieving a more stable sealing effect.

[0019] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0020] Example 1
[0021] like Figure 1-5 As shown, the bronchoscopy auxiliary device for the respiratory anesthesia tubing of this embodiment includes a telescopic tube 1 and an outlet tube 2 and an inlet tube 5 located at both ends of the telescopic tube 1. Preferably, the telescopic tube 1 has an elastic telescopic function. The outlet tube 2 has a retaining tube 3 at its outlet for docking with the bronchoscope insertion port of the laryngeal mask external tube. The inlet tube 5 has a wrapping air bag 6 at its inlet for wrapping the bronchoscope fiber bundle from the outside. An air inlet tube 8 is connected to the wrapping air bag 6. A sealing membrane 11 is provided between the wrapping air bag 6 and the inlet tube 5.
[0022] When performing bronchoscopy on a patient, after completing the preparatory work such as placing the laryngeal mask in place, installing the laryngeal mask external tube, and connecting the anesthesia machine, the bronchoscope with the locking tube 3 inserted into the laryngeal mask external tube is inserted into the mouth. The bronchoscope fiber bundle can pass through the wrapping cuff 6, sealing membrane 11, telescopic tube 1, outlet tube 2, locking tube 3, laryngeal mask external tube, and laryngeal mask trachea from the center, so that the bronchoscope is inserted into the appropriate part of the patient's trachea. Then, air is inflated into the wrapping cuff 6 through the air inlet tube 8, and the wrapping cuff 6 can be deformed, thereby achieving the effect of wrapping the bronchoscope fiber bundle from the outside. This completes the installation of the auxiliary device for bronchoscopy.
[0023] After installation, the bronchoscope, the wrapping cuff 6, the sealing membrane 11, and the inlet tube 5 work together to seal the bronchoscope insertion port of the laryngeal mask airway. The bronchoscope can move freely inside the patient's trachea. During the aspiration and desorption of the bronchoscope fiber bundle, the inlet tube 5 should be held. During this process, on the one hand, the telescopic tube 1 can extend and retract in coordination with the movement of the bronchoscope. On the other hand, when the bronchoscope and the wrapping cuff 6 move as a whole, the sealing membrane 11 can be adaptively folded, unfolded, or stretched to a slight deformation under the action of the wrapping cuff 6. This ensures that the wrapping cuff 6 always moves synchronously with the part of the bronchoscope that is wrapped, avoiding the problem of air leakage caused by the movement of the bronchoscope leading to a decrease in the tightness of the wrapping cuff 6.
[0024] Preferably, the airbag 6 has a ring structure and includes an elastic part and a rigid part. The elastic part is located on the inner arc surface of the airbag 6. In this embodiment, the inner arc surface of the airbag 6 is made of elastic material. After the airbag 6 is inflated, the inner wall of the airbag 6 will quickly bulge inward to achieve the effect of wrapping the bronchoscope, making the operation faster.
[0025] Preferably, the outer side of the airbag 6 is provided with an air reservoir 7 for inflating the airbag 6. The air inlet pipe 8 is connected to the air reservoir 7. The airbag 6 can be inflated by squeezing the air reservoir 7, without the need for additional inflation tools, making the operation convenient and efficient.
[0026] Preferably, the air reservoir 7 has a non-annular structure and is fitted on the outside of the airbag 6, with the air inlet pipe 8 located at one end of the non-annular structure. The outside of the air reservoir 7 is provided with an adhesive layer 9 and a shielding film 10 is provided on the outside of the adhesive layer 9. When in use, the shielding film 10 is torn off, and the air reservoir 7 is rolled up and folded from the end away from the air inlet pipe 8 to squeeze all the gas in the air reservoir 7 into the airbag 6. The air reservoir 7 will remain rolled up under the action of the adhesive layer 9 to prevent gas backflow.
[0027] Preferably, the passage of the air inlet pipe 8 is opened by the airflow when the air reservoir 7 inflates the enclosing airbag 6. The air inlet pipe 8 can be sealed in one go by heat sealing or internal bonding, which can prevent the gas in the air reservoir 7 from partially entering the enclosing airbag 6 at the beginning, thus blocking the central through hole of the enclosing airbag 6 and interfering with the operation of inserting the bronchoscope fiber bundle, and further improving the convenience of operation.
[0028] Preferably, a sealing element 4 is provided on the outer side of the clamping tube 3. The clamping tube 3 is preferably made of rubber, and the sealing element 4 can be a rubber ring or an annular airbag.
[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
