Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically refers to a nursing sputum suction device for an intensive care unit. Background Art

[0002] The human respiratory epithelial cells secrete mucus, which contains some dust, bacteria and other impurities. When the respiratory tract is inflamed or infected, the secretions increase, leading to the production of sputum. Under normal circumstances, the human body will expel sputum through coughing or inhaling through the nose. However, for critically ill patients, due to various reasons, they cannot cough or expectorate effectively, so they need to use a suction device to help them expectorate.

[0003] The existing sputum suction device consists of a sputum suction tube and a negative pressure pump. When suctioning sputum, the sputum suction tube is inserted into the patient's mouth or trachea, and then the negative pressure pump is operated to generate negative pressure, so that the sputum is sucked into the sputum suction tube, and then the sputum is discharged through the sputum suction tube to complete a sputum suction process. At present, there are still some defects and shortcomings in the use of lung clearing and sputum removal devices. The specific areas that need improvement are as follows: Most of the current lung clearing and sputum removal devices can only perform sputum suction operations. When dealing with thick sputum, additional expectorant treatment is required. It is necessary to intubate separately or remove the sputum suction tube before expectorant treatment. Usually, multiple repeated treatments are required, which affects the patient's comfort and thoroughness during the lung clearing and sputum removal process to a certain extent.

[0036] like Figure 3 , Figure 6 and Fig.12 As shown, the left bottle 1 is connected to the left long tube 101, which is connected to the left input port 503; the left bottle 1 is connected to the left short tube 102, which is connected to the exchange cabin 304; the right bottle 2 is connected to the right long tube 201, which is connected to the right input port 504; the right bottle 2 is connected to the right short tube 202, which is connected to the exchange cabin 304.

[0037] When in use, the left bottle 1 is used to collect sputum of the patient, and the right bottle 2 is filled with therapeutic drugs for auxiliary expectoration treatment. The locking device 310 exchanges air with the outside through the vent 331, and the output port 502 is connected to the medical hose, and the medical hose is inserted into the patient's affected part; during the expectoration treatment process, the electromagnet group 305 is in a closed state, and the coil magnet 509 is in an open state. At this time, the coil magnet 509 generates a magnetic field, and the permanent magnet 510 is attracted to the three-way cavity 501 and squeezes the reset spring 507. The output port 502 and the right input port 504 are in a connected state, and the transmission motor 326 is started, and the transmission motor 326 drives the transmission gear 325 The transmission gear 325 rotates to drive the transmission gear ring 324 to rotate, and the transmission gear ring 324 rotates to drive the right turntable 318 to rotate. The left turntable 321 keeps synchronous rotation with the right turntable 318 through the linkage shaft 317. The right turntable 318 rotates to drive the right piston 320 to slide in the right cavity 330 through the right connecting rod 319. The left turntable 321 rotates to drive the left piston 323 to slide in the left cavity 329 through the left connecting rod 322. The sliding directions of the right piston 320 and the left piston 323 are always opposite. During the upward movement of the left piston 323, the locking electromagnet 313 is in the closed state. Under the support of the elastic force of the locking spring 314, the locking electromagnet 313 is in the closed state. The lock slider 312 is close to the side where the left chamber 329 is located. As the left piston 323 moves upward, the pressure in the left chamber 329 increases, pushing the closing ball 307 above the left chamber 329 and squeezing the closing spring 308. The air enters the exchange chamber 304 through the closing chamber 306, and then enters the right bottle 2 from the exchange chamber 304 through the right short tube 202.

When the left piston 323 moves upward to the top of the left chamber 329, the left piston 323 contacts the left trigger 327. The left trigger 327 receives the trigger signal to start the locking electromagnet 313, and the locking electromagnet 313 attracts the locking slider 312. At this time, the locking slider 312 is close to the right chamber 330, and the right chamber 330 is closed. At this time, the right piston 320 starts to move from bottom to top, and continues to transport air into the right bottle 2. During the movement of the left piston 323 from bottom to top, the right piston 320 moves from top to bottom, and the right piston 320 has contacted the right trigger 328. The right trigger 328 controls the locking electromagnet 313 to close, and the right chamber 330 is in an open state. At this time, the right chamber 330 is connected to the outside air through the rectangular outer chamber 311, and the air pressure is balanced;When suction operation is performed, the triggering mode of the left trigger 327 and the right trigger 328 is replaced, the electromagnet group 305 is in the open state, the electromagnet group 305 absorbs two groups of closing balls 307, the closing balls 307 are close to the upper opening of the closing cabin 306, and the closing balls 307 squeeze the closing springs 308, the coil magnet 509 is in the closed state, and is squeezed by the elastic force of the return spring 507, the closing piston 508 moves closer to the coil magnet 509, the output port 502 and the left input port 503 are in the connected state, at the same time, the left trigger 327 controls the locking electromagnet 313 to close, and the right trigger 328 controls the locking electromagnet 313 to open. At this time, when the left piston 323 moves upward, the locking electromagnet 313 is started, and the locking slider 312 is close to the right cavity 330. The left cavity 329 is in the open state, and the right cavity 330 is Sealed state, while the right piston 320 moves downward, the pressure in the right chamber 330 decreases, at this time, the elastic force and negative pressure of the closing spring 308 are greater than the magnetic force of the electromagnet group 305 on the closing ball 307, the closing ball 307 is sucked downward, the left bottle 1 maintains pressure balance with the exchange cabin 304 through the left short tube 102, the left bottle 1 is negative pressure, and the sputum is sucked into the left bottle 1 through the reversing mechanism 5 by the negative pressure, when the right piston 320 moves to the bottom of the right chamber 330, the left piston 323 moves to the top of the left chamber 329, the left trigger 327 controls the locking electromagnet 313 to close, the locking slider 312 approaches the left chamber 329, the right chamber 330 is equal to the outside pressure, the closing ball 307 above the right chamber 330 closes with the top opening of the closing cabin 306 again, then the left piston 323 moves downward, and the right piston 320 moves upward, and they move in a cycle. ;
