Description

Technical Field

[0001] This utility model belongs to the field of medical devices for bronchoalveolar lavage, specifically relating to a three-way negative pressure auxiliary connection device for bronchoalveolar lavage. Background Technology

[0002] Bronchoalveolar lavage is a medical procedure commonly used to treat lung diseases or improve lung function. This procedure involves injecting a saline or medicated solution into the patient's alveoli and then removing the fluid and any sputum or other secretions by suction or drainage. This method can help clear sputum from the lungs, improve gas exchange, and help treat certain lung infections or diseases, especially those that cause the lungs to fill with fluid or secretions.

[0003] Existing auxiliary connection devices used in bronchoalveolar lavage surgery have too many connecting tubes. Since bronchoalveolar lavage fluid usually needs to be sent for testing, too many connecting tubes often make them prone to cross-contamination. Furthermore, the connections between the tubes are relatively loose, and they are prone to detachment under external force, thus contaminating medical staff. In addition, many connecting tubes require the user to assemble them, and the area where the user comes into contact with the connecting tubes often affects the results of bronchoalveolar lavage fluid tests.

[0004] Therefore, to address the problems of the aforementioned auxiliary connection devices being prone to cross-contamination due to their numerous waste tubes during bronchoalveolar lavage surgery, which also affects the ease of tube assembly and results in poor connections between tubes that are easily broken by external forces, a three-way negative pressure auxiliary connection device for bronchoalveolar lavage has been developed. By adding a three-way tube structure with built-in valve control, a double flexible tube structure, a press-type output structure, and a snap-fit ​​connection structure to the auxiliary connection device, the safety of the device during use can be greatly improved, the stability of its connection structure during use can be enhanced, and the ease of use of the device can also be improved. Utility Model Content

[0005] To overcome the problems that the auxiliary connection device has a large number of hoses and connectors when used in bronchoalveolar lavage surgery, which can easily cause the lavage fluid to contaminate the pipes and the pipes to detach.

[0006] The technical solution of this utility model is as follows: a three-way negative pressure auxiliary connection device for alveolar lavage, including a nozzle and a scale line, as well as an lavage bottle, a cap assembly and a hose assembly. The upper end of the cap assembly is limited and installed with a hose assembly connected to the bronchus. The upper outer wall of the lavage bottle has an external thread. The lower outer wall of the lavage bottle is fixedly connected to a support frame. The lower end of the support frame is fixedly connected to a base. The front outer wall of the support frame has a first groove. The inner wall of the base is equipped with a clamping ring for clamping and fixing the outer wall of the test tube.

[0007] Preferably, the two sets of hoses on the canister cap assembly can reduce the number of pipes required for the device during use, thereby reducing the need for the user to come into contact with the pipes and reducing the possibility of the pipes falling off during use. The three-way structure with a built-in control valve on the canister cap assembly can perform isolated bronchoalveolar lavage and bronchoscopy as needed for surgery, preventing bronchoalveolar lavage fluid from contaminating the bronchoscopy. The clamping ring, together with the base, can clamp and fix the test tube, so that workers can collect the bronchoalveolar lavage fluid in the lavage bottle.

[0008] Preferably, the outer wall of the lavage bottle is fixed with equidistant graduation lines, and the lower end of the lavage bottle is fixed with a press-type nozzle. The nozzle is located on the inner wall of the support frame. During use, the press-type nozzle allows the user to easily remove the bronchoalveolar lavage fluid from the lavage bottle through a test tube for testing. The graduation lines clearly show the volume of bronchoalveolar lavage fluid contained in the lavage bottle, allowing the user to observe the volume of the bronchoalveolar lavage fluid.

[0009] Preferably, the can lid assembly includes a filling lid, a first hose, a second hose, a first connector, a first interface, a second interface, an internal thread, a tee pipe, a control valve, an output pipe, a manual switch, and a through hole. The first hose and the second hose are fixedly connected to the front and rear sides of the upper end of the filling lid, respectively. The first connector is fixedly connected to the second hose. The inner wall of the filling lid is provided with an internal thread that is compatible with the external thread. In use, the filling lid and the filling bottle installed by the thread can be easily assembled by the user.

[0010] Preferably, the lower rear side of the lavage cap has a first interface that communicates with the second hose, and the lower front side of the lavage cap has a second interface that communicates with the first hose. The first and second interfaces are equipped with two upper interfaces of a U-shaped tee tube. In use, the number of tubes that need to be connected to the device can be reduced by using the first and second hoses, and the need for the user to contact the tubes can be reduced, so as to avoid affecting the results of the bronchoalveolar lavage fluid test and reduce the possibility of the tubes falling off during use.

[0011] Preferably, the lower end of the tee tube is equipped with an output tube, and the upper end of the lower end of the tee tube is equipped with a control valve, which is a ball valve. The center of the upper and lower ends of the irrigation cap has a through hole. The upper end of the tee tube is equipped with a manual switch that is connected to the control valve via a connecting rod. The knob of the manual switch passes through the through hole and is located on the upper end of the irrigation cap. In use, the tee tube, in conjunction with the ball control valve, can be used to control the negative pressure device to be directly connected to the connecting tube as needed for bronchoscopy, or to connect the negative pressure device to the irrigation bottle and the connecting tube during alveolar lavage, thereby reducing the number of tube connections and preventing cross-contamination between tubes.

[0012] Preferably, the connecting assembly includes a connecting pipe, a limiting buckle, a second connector, and a limiting groove. The second connector is installed at the upper end of the first flexible hose, and a limiting groove is formed on the inner wall of the second connector. In use, the limiting buckle and the limiting groove can improve the stability of the connection between the connecting pipe and the first flexible hose, so as to prevent them from falling off during use.

[0013] Preferably, a limiting buckle is fixed to the outer wall of the left end of the connecting tube, and the limiting buckle is compatible with the limiting groove. The connecting tube is a corrugated hose. During use, the corrugated hose connecting tube can be bent and adjusted at a certain angle according to the user's needs, making it more suitable for bronchoalveolar lavage surgery.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using a three-way tube in conjunction with a ball-shaped control valve, the negative pressure device can be directly connected to the connecting tube as needed for bronchoscopy, or the negative pressure device can be connected to the lavage bottle and connecting tube during bronchoalveolar lavage to reduce the number of tube connections and thus prevent cross-contamination between tubes.

[0016] 2. The use of the first and second hoses can reduce the number of tubes that need to be connected during the use of the device and reduce the need for the user to contact the tubes, so as to avoid affecting the results of bronchoalveolar lavage fluid examination and also reduce the possibility of tubes dislodging during use.

[0017] 3. The push-button nozzle allows users to easily extract bronchoalveolar lavage fluid from the lavage bottle using a test tube, facilitating its testing.

[0018] 4. The use of limit buckles and limit slots can improve the stability of the connection between the connecting pipe and the first flexible hose, preventing them from falling off during use.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1-5 This utility model provides an embodiment: a three-way negative pressure auxiliary connection device for alveolar lavage, including a nozzle 4 and a scale line 5, as well as an lavage bottle 104, a cap assembly, and a hose assembly. The upper end of the cap assembly is fitted with a hose assembly connected to a bronchus. The upper outer wall of the lavage bottle 104 has an external thread 105, and the lower outer wall of the lavage bottle 104 is fixedly connected to a support frame 102. The lower end of the support frame 102 is fixedly connected to a base 101. The front outer wall of the support frame 102 has a first groove 103. The inner wall of the base 101 is fitted with a clamping ring 106 for fixing the outer wall of the test tube. The two sets of hoses on the cap assembly reduce the number of pipes required for assembly during use, thus reducing the user's contact with the pipes. This design also reduces the possibility of the tubing detaching during use. The three-way structure with a built-in control valve on the cap assembly allows for isolated bronchoalveolar lavage and bronchoscopy as needed during surgery, preventing bronchoalveolar lavage fluid from contaminating the bronchoscopy. The outer wall of the lavage bottle 104 is fixed with equidistant graduations 5, and the lower end of the lavage bottle 104 is fixed with a press-type nozzle 4. The nozzle 4 is located on the inner wall of the support frame 102. During use, the press-type nozzle 4 allows the user to easily remove the bronchoalveolar lavage fluid from the lavage bottle 104 using a test tube for testing. The graduations 5 clearly indicate the volume of bronchoalveolar lavage fluid contained in the lavage bottle 104, allowing the user to observe the volume of the bronchoalveolar lavage fluid.

[0028] Please see Figure 4 In this embodiment, the can lid assembly includes a filling lid 201, a first hose 202, a second hose 203, a first connector 204, a first interface 205, a second interface 206, an internal thread 207, a tee pipe 208, a control valve 209, an output pipe 210, a manual switch 211, and a through hole 212. The first hose 202 and the second hose 203 are fixedly connected to the front and rear sides of the upper end of the filling lid 201, respectively. The first connector 204 is fixedly connected to the second hose 203. The inner wall of the filling lid 201 has an inner thread. The thread 207, internal thread 207, is compatible with external thread 105. During use, the threaded flushing cap 201 and flushing bottle 104 allow for quick assembly by the user. The lower rear end of the flushing cap 201 has a first interface 205 communicating with the second flexible tube 203, and the lower front end of the flushing cap 201 has a second interface 206 communicating with the first flexible tube 202. The first interface 205 and the second interface 206 contain two U-shaped tee tubes 208 with two upper interfaces. During use… The use of the first hose 202 and the second hose 203 reduces the number of pipes required for the device during use and minimizes user contact with the pipes, thus avoiding interference with bronchoalveolar lavage fluid test results and reducing the possibility of pipe detachment during use. An output pipe 210 is installed at the lower end of the three-way connector 208, and a control valve 209 (a ball valve) is installed at the upper end of the lower end of the three-way connector 208. Through holes 212 are provided at the center of both the upper and lower ends of the lavage cover 201. A manual switch 211 is installed at the upper end and connected to the control valve 209 via a connecting rod. The knob of the manual switch 211 passes through the through hole 212 and is rotated and located at the upper end of the irrigation cover 201. In use, the negative pressure device can be directly connected to the connecting tube 301 according to the needs of bronchoscopy through the three-way tube 208 and the ball-shaped control valve 209, or the negative pressure device can be connected to the irrigation bottle 104 and the connecting tube 301 during alveolar lavage to reduce the number of pipe connections and thus prevent cross-contamination between pipes.

[0029] Please see Figure 5In this embodiment, the connecting assembly includes a connecting tube 301, a limiting buckle 302, a second connector 303, and a limiting groove 304. The second connector 303 is installed on the upper end of the first flexible tube 202. The inner wall of the second connector 303 is provided with a limiting groove 304. In use, the limiting buckle 302 and the limiting groove 304 can improve the stability of the connection between the connecting tube 301 and the first flexible tube 202 to prevent them from falling off during use. The limiting buckle 302 is fixed to the outer wall of the left end of the connecting tube 301. The limiting buckle 302 and the limiting groove 304 are compatible. The connecting tube 301 is a corrugated flexible tube. In use, the corrugated flexible connecting tube 301 can be bent and adjusted at a certain angle according to the user's needs, so as to better suit the bronchoalveolar lavage surgery.

[0030] When working, first, install the connector of the negative pressure device into the first connector 204, and connect the right end of the connecting tube 301 to the bronchoscope. Then, install the limiting buckle 302 into the limiting slot 304 to limit the connecting tube 301 into the second connector 303.

[0031] During bronchoalveolar lavage, the manual switch 211 is turned, which drives the control valve 209 to open and close, so that the three-way tube 208 is connected to the first hose 202, the second hose 203 and the output tube 210, so that the bronchoalveolar lavage fluid is drawn into the lavage bottle 104, and the test tube is placed in the support frame 102. The bronchoalveolar lavage fluid is output into the test tube by pressing the nozzle 4, so that the user can test it.

[0032] During bronchoscopy, the manual switch 211 is turned, which drives the control valve 209 to open and close, so that the three-way tube 208 is connected to the first hose 202 and the second hose 203, so that the negative pressure device and the connecting tube 301 are directly connected to the bronchoscopy.

[0033] When the bronchoalveolar lavage fluid in the lavage bottle 104 needs to be sent for testing, first press the test tube into the clamping ring 106 to hold and fix it, hold the bottom of the test tube by hand, and then push the test tube to move it upward along the inner wall of the clamping ring 106 to squeeze the nozzle 4. The nozzle 4 then outputs the bronchoalveolar lavage fluid in the lavage bottle 104 into the test tube for testing, so that the doctor can test the bronchoalveolar lavage fluid.

[0034] Through the above steps, the three-way pipe 208, in conjunction with the control valve 209, can be used separately according to the tubing used for bronchoscopy and bronchoalveolar lavage to prevent cross-contamination between the tubing. The limiting buckle 302, in conjunction with the limiting groove 304, improves the stability of the connection between the connecting pipe 301 and the first flexible tube 202 to prevent it from falling off during use. This solves the problem that when the auxiliary connecting device is used for bronchoalveolar lavage surgery, the large number of tubes and connecting ports makes it easy for the lavage fluid to contaminate the tubing, and the tubing is also prone to falling off.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
