Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel adapter for fiberoptic bronchoscopy anesthesia. Background Art

[0002] Fiberoptic bronchoscope is abbreviated as fiberoptic bronchoscope. It is suitable for observation of lesions in lobes, segments and subsegments of bronchus, biopsy sampling, bacteriology, cytology and other medical operations. Fiberoptic bronchoscope is equipped with a biopsy sampling mechanism, which can help patients find early lesions and carry out internal surgical operations such as polypectomy. It is a good precision instrument for bronchial and lung disease research and postoperative examination.

[0003] During endobronchial fiberoptic bronchoscopic surgery, the patient is first given general anesthesia and maintained with ventilation through an endotracheal tube or laryngeal mask. During this process, a three-way adapter is required to connect the endotracheal tube or laryngeal mask, the ventilator circuit, and the fiberoptic bronchoscopic operation to facilitate the related surgical operations of the fiberoptic bronchoscopic operation while maintaining ventilation. However, the current adapter has the problem of poor sealing when used. When the fiberoptic bronchoscopic operation is connected, gas may overflow from the gap between the fiberoptic bronchoscopic operation and the adapter, resulting in insufficient air pressure, affecting oxygen supply and related surgical operations, and the existing products are not suitable for fiberoptic bronchoscopic operation with different diameters.

[0004] In order to solve the above technical problems, a Chinese patent (publication number: CN213589522U) discloses a special connector that can be used for fiberoptic bronchoscopy through a tracheal tube during mechanical ventilation. A highly elastic sealing film is arranged in the fiberoptic bronchoscopy insertion port of the special connector, which allows the fiberoptic bronchoscopy to pass through while the highly elastic sealing film is pressed against the outer wall of the fiberoptic bronchoscopy to seal and prevent air leakage.

[0005] However, the high elastic sealing membrane of the special joint is located in the insertion port of the fiberoptic bronchoscope. After the fiberoptic bronchoscope is inserted, it is closely matched with the high elastic sealing membrane. The fiberoptic bronchoscope needs to be adjusted up and down for related medical operations. Due to the friction between the fiberoptic bronchoscope and the high elastic sealing membrane, it is difficult for the fiberoptic bronchoscope to move up and down a certain distance, which is not conducive to medical staff to perform related medical operations. Therefore, a new type of fiberoptic bronchoscope anesthesia adapter is proposed to achieve the effect of preventing air leakage and can be applied to fiberoptic bronchoscopes of different diameters. Utility Model Content

[0006] The utility model aims to provide a novel adapter for fiberoptic bronchoscope anesthesia, so as to solve the technical problems in the prior art that the adapter for anesthesia cannot prevent air leakage and cannot be applied to fiberoptic bronchoscopes with different tube diameters.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A novel adapter for bronchoscopic anesthesia comprises a three-way pipe, the three-way pipe is a T-shaped structure, a ventilator connector pipe is provided at the end of the bifurcated pipe of the three-way pipe, a patient end connector pipe is provided at one end of the straight pipe of the three-way pipe, a second elastic flap away from the patient end connector pipe is provided on the inner wall of the straight pipe of the three-way pipe, the second elastic flap is arranged in a shingle-like manner, an elastic flap is provided between adjacent flap flaps of the second elastic flap, the elastic flap is distributed radially along the second elastic flap in the three-way pipe, and the length of the elastic flap is less than the radius of the inner diameter of the second elastic flap in the three-way pipe.

[0009] The principle of the technical solution: medical staff insert the patient-end joint tube into the appropriate position of the patient's throat according to the clinical operation routine, connect the ventilator joint tube to the ventilator and perform mechanical ventilation on the patient, and pass the front end of the fiberoptic bronchoscope through the second elastic valve of the three-way tube and the patient-end joint tube in turn into the appropriate depth position in the human body to complete the intubation. Because the second elastic flap is arranged in a shingle-like manner, the air tightness of the three-way tube can still be guaranteed when fiberoptic bronchoscopes of different diameters are inserted, and the setting of the elastic sheet further ensures and improves the air tightness of the three-way tube. Because the second elastic flap is elastic, when the fiberoptic bronchoscope is inserted, the second elastic flap can be recessed in the insertion direction of the three-way tube to achieve inversion, and can also bulge out along the insertion direction of the three-way tube when it is pulled out, so as to facilitate the up and down movement of the fiberoptic bronchoscope to perform related operations and always ensure that there is no air leakage; when the fiberoptic bronchoscope is completely pulled out, the second elastic flap can return to its original state under the action of elasticity, achieving a sealing effect.

[0010] Furthermore, a protective cap is provided at one end of the straight tube of the three-way pipe away from the patient-end connecting pipe, the protective cap is provided with a through opening, and a sealing plug matched with the through opening is provided at the through opening of the protective cap, and fixing lines are provided at both ends of the protective cap, and the fixing lines are elastic. A limiting hole is provided on one side of the bifurcated tube of the three-way pipe, and the fixing line passes through the limiting hole and is distributed along the outer circumference of the three-way pipe, and one end of the sealing plug is fixedly connected to the protective cap.

[0011] The setting of the limiting hole can prevent the protective cap from falling or being lost, the elastic fixing line can firmly connect the protective cap to the three-way pipe, and the sealing plug has a double sealing effect after the use of the fiberoptic bronchoscope.

[0012] Furthermore, a first elastic flap is provided on the inner wall of the through opening, the first elastic flap is a three-flap structure, the first elastic flap is annular, and two adjacent flap pieces of the first elastic flap are superimposed.

[0013] The first elastic flap plays a double sealing role when the bronchoscope is used, and the three-flap structure can effectively reduce the friction between the bronchoscope and the first elastic flap, thereby facilitating related operations of moving the bronchoscope up and down.

[0014] Furthermore, a connecting wire is provided at one end of the sealing plug, the sealing plug is arranged on one side of the wire connection, one end of the connecting wire is fixedly connected to the protective cap, the sealing plug is conical, and the sealing plug sleeve is provided with an annular convex strip, and when the protective cap is in a sealing state, the length from the center of the sealing plug to the free end of the connecting wire is greater than the length from the center of the sealing plug to the periphery of the protective cap.

[0015] The provision of the annular convex strip and the connecting line on the sealing plug is beneficial to the sealing performance of the sealing plug and the removal of the sealing plug.

[0016] Furthermore, the end of the three-way pipe and the patient end joint pipe is threadedly connected, and the ventilator joint pipe is a spiral rib structure.

[0017] The spiral rib structure makes the ventilator connector tube have good anti-twisting performance.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. It is not only suitable for fiberoptic bronchoscopes with different diameters, but also has a good effect in preventing air leakage.

[0020] 2. On the basis of good air leakage prevention, the bronchoscope can also be moved up and down in the human body, making it very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0026] like Figure 1 to Figure 2As shown, a new type of adapter for bronchoscopic anesthesia includes a three-way pipe 1, which is a T-shaped structure. A ventilator connector pipe 8 is provided at the end of the bifurcated pipe of the three-way pipe 1. The ventilator connector pipe 8 is a spiral rib structure. The bottom end of the straight pipe of the three-way pipe 1 is threadedly connected to a patient end connector pipe 2. The straight pipe of the three-way pipe 1 is provided with a second elastic flap 7 close to the top of the straight pipe of the three-way pipe 1. The second elastic flap 7 is located above the bifurcated pipe of the three-way pipe 1 and in the middle of the upper part of the straight pipe of the three-way pipe 1. The second elastic flap 7 is arranged in an imbricate manner. An elastic flap 9 is provided between adjacent flap pieces of the second elastic flap 7. The elastic flap 9 is distributed radially along the second elastic flap 7 in the three-way pipe 1. The length of the elastic flap 9 is less than the radius of the inner diameter of the second elastic flap 7 in the three-way pipe 1.

[0027] A protective cap 3 is provided at the top of the straight pipe of the tee pipe 1, and fixing lines 10 are provided at both ends of the protective cap 3. A limiting hole 11 is provided at the bottom of the bifurcated pipe of the tee pipe 1. The fixing line 10 passes through the limiting hole 11 and is distributed along the outer periphery of the tee pipe 1, so as to prevent the protective cap 3 from falling off or being lost. The fixing line 10 is elastic and can make the protective cap 3 and the tee pipe 1 firmly connected; the protective cap 3 is provided with a through opening 4, and a sealing plug 5 adapted to the through opening 4 is provided at the through opening 4 of the protective cap 3. A connecting line 12 is provided at one end of the sealing plug 5, and the free end of the connecting line 12 is fixedly connected to the protective cap 3. The sealing plug 5 is conical, and the sealing plug 5 is sleeved with an annular convex strip 13. When the protective cap 3 is in a sealed state, the length from the center of the sealing plug 5 to the free end of the connecting line 12 is greater than the length from the center of the sealing plug 5 to the periphery of the protective cap 3. A first elastic flap 6 is provided on the inner wall of the through opening 4. The first elastic flap 6 is a three-flap structure, and the first elastic flap 6 is annular, and two adjacent flaps in the first elastic flap 6 are superimposed.

[0028] The specific implementation process is as follows:

[0029] Medical staff insert the patient-end connecting tube 2 into the appropriate position of the patient's throat in accordance with clinical operating routine, connect the ventilator connecting tube 8 to the ventilator and perform mechanical ventilation on the patient, put the protective cap 3 on the corresponding end of the three-way tube 1, open the sealing plug 5, and pass the front end of the bronchoscope through the first elastic valve 6 and the second elastic valve 7 of the three-way tube 1 in sequence, as well as the patient-end connecting tube 2 into the appropriate depth position in the human body to complete the intubation. Since the second elastic flap 7 is arranged in an imbricate manner, the air tightness of the three-way tube 1 can still be ensured when the bronchoscopes of different diameters are inserted, and the air tightness of the three-way tube 1 is further ensured and improved by the provision of the elastic sheet 9. Since the second elastic flap 7 is elastic, when the bronchoscope is inserted, the second elastic flap 7 can be recessed in the insertion direction of the three-way tube 1 to achieve inversion, and can also be convex along the insertion direction of the three-way tube 1 when it is pulled out, so as to facilitate the up and down movement of the bronchoscope to perform related operations and always ensure that there is no air leakage; when the bronchoscope is completely pulled out, the second elastic flap 7 can return to its original state under the action of elasticity, thereby achieving a sealing effect;

[0030] When the bronchoscope is in use, the first elastic valve 6 plays a double sealing role, and the three-flap structure can effectively reduce the friction between the bronchoscope and the first elastic valve 6, thereby facilitating related operations of moving the bronchoscope up and down.

[0031] When the fiberoptic bronchoscope is used up and the patient is waiting to wake up from anesthesia, the sealing plug 5 is put on to achieve a double sealing effect.

[0032] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical scheme or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical scheme of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
