Description

Technical Field

[0001] The present invention belongs to the technical field of expectoration treatment, and in particular relates to an expectoration device for thoracic surgery nursing. Background Art

[0002] Expectoration therapy, a method that uses physical, pharmacological, or mechanical means to help patients clear respiratory secretions, aims to maintain airway patency and is an important treatment for respiratory diseases. This method is particularly suitable for patients with chronic obstructive pulmonary disease, pneumonia, bronchiectasis, and those recovering from surgery. Expectoration therapy not only relieves patients' respiratory symptoms but also reduces the risk of infection and improves their quality of life. In practice, medical staff will select the appropriate treatment method based on the patient's specific condition to ensure its safety and effectiveness.

[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 to suck the sputum 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 deficiencies in the use of sputum removal devices. The specific areas that need improvement are as follows: Most of the sputum suction devices today can only perform sputum suction operations. When dealing with thick sputum, additional expectorant treatment is required. Separate intubation is required or expectorant treatment is performed after the sputum suction tube is removed. Repeated treatment is usually required, which to some extent affects the comfort and thoroughness of the patient in the process of clearing the lungs and expectorating. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a sputum removal device for thoracic surgery nursing to solve the technical problems raised in the background technology.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a sputum removal device for thoracic surgery nursing, comprising a chassis, a transition mechanism, an atomizing mechanism, a two-way oscillating mechanism, a sputum suction mechanism and an air supply system. The transition mechanism, the atomizing mechanism, the two-way oscillating mechanism, the sputum suction mechanism and the air supply system are all arranged in the chassis, the transition mechanism is ventilatedly connected to the atomizing mechanism, the transition mechanism is also ventilatedly connected to the sputum suction mechanism, the air supply system is ventilatedly connected to the atomizing mechanism, the air supply system is also ventilatedly connected to the sputum suction mechanism, the two-way oscillating mechanism is transmission-connected to the atomizing mechanism, and the two-way oscillating mechanism and the sputum suction mechanism are simultaneously transmission-connected to the atomizing mechanism.

[0006] Further, the transition mechanism includes an intermediate chamber, a collection bottle, and a humidifying bottle. The intermediate chamber is disposed inside the chassis, the collection bottle is disposed inside the intermediate chamber, the humidifying bottle is disposed inside the intermediate chamber. The top of the collection bottle is connected with a left short tube and a right short tube, and the top of the humidifying bottle is connected with a humidifying short tube and a humidifying long tube. By means of double-bottle separate control, the humidifying bottle wets the oxygen to reduce airway dryness irritation; the collection bottle stores sputum independently to avoid backflow pollution.

[0007] Further, the atomization mechanism includes an atomization channel and an atomization system. The atomization system is disposed inside the chassis, and the atomization system is disposed inside the atomization channel. An atomization oscillation diaphragm is provided on the side wall of the atomization channel.

[0008] Further, the atomization system includes a Venturi tube and a middle medicine tube. The Venturi tube is disposed inside the atomization channel, and a medicine liquid bottle is installed on the side wall of the atomization channel. One end of the middle medicine tube is communicated with the throat of the Venturi tube, and the other end of the middle medicine tube is communicated with the bottom of the medicine liquid bottle. A delivery channel is provided at the top of the atomization channel. Through the synergistic effect of the Venturi tube and the middle medicine tube, the phlegm-dissolving medicine in the medicine liquid bottle is automatically extracted by air flow negative pressure and atomized without an additional power source. The atomized medicine is transported to the patient's airway along with the oxygen, directly diluting the sputum and moistening the mucosa, reducing the mechanical damage of the suction tube to the airway, avoiding the cumbersome process of repeatedly inserting and pulling out the tube in the traditional operation, and improving the treatment efficiency and patient comfort.

[0009] Further, the sputum suction mechanism includes a disinfection system and a sputum suction channel. The disinfection system is disposed inside the chassis, the sputum suction channel is disposed inside the chassis, and the sputum suction channel is communicated with the left short tube. A sputum suction oscillation diaphragm is provided on the side wall of the sputum suction channel. Further, the disinfection system includes a disinfection channel, a disinfection chamber, an air extraction pipeline, and a replacement filter element. The disinfection chamber is disposed inside the chassis, the disinfection channel is communicated with the disinfection chamber, the air extraction pipeline is communicated with the disinfection chamber, and the replacement filter element is installed on the air extraction pipeline. The sucked gas enters the disinfection chamber through the disinfection channel and is filtered by the replacement filter element to remove pathogens, avoiding cross-infection.

[0010] Further, the disinfection channel is communicated with the sputum suction channel.

[0011] Further, the bidirectional oscillation mechanism includes an oscillation chamber, a left limit rod, a right limit rod, a return spring, a traction piece, a balance spring, an attracting electromagnet, an atomizing connecting rod, and a sputum suction connecting rod. The oscillation chamber is arranged inside the chassis. The left limit rod is arranged inside the oscillation chamber. The right limit rod is arranged inside the oscillation chamber. The traction piece is slidably connected to both the left limit rod and the right limit rod. One end of the return spring is connected to the upper inner wall of the oscillation chamber, and the other end of the return spring is connected to the upper end of the traction piece. One end of the balance spring is connected to the lower end of the traction piece, and the other end of the balance spring is connected to the lower inner wall of the oscillation chamber. The atomizing connecting rod is rotatably connected to one side of the traction piece, and the sputum suction connecting rod is rotatably connected to the other side of the traction piece. Compared with traditional mechanical mechanisms (usually difficult to exceed dozens of Hz due to inertia and mechanical stress) and pneumatic mechanisms (limited by gas compressibility and valve response), using an attracting electromagnet to attract the traction piece for oscillation can easily achieve high-frequency oscillations in the hundreds of Hz or even kHz range, and the oscillation frequency is directly controlled by the frequency of the pulsed current. Adjusting the frequency of the electrical signal can precisely change the oscillation frequency, and the oscillation amplitude can be finely controlled by adjusting the magnitude or pulse width of the pulsed current.

[0012] Further, the atomizing connecting rod is simultaneously rotatably connected to an atomizing oscillation diaphragm; the sputum suction connecting rod is simultaneously rotatably connected to a sputum suction oscillation diaphragm. By driving the traction piece with an attracting electromagnet, the atomizing oscillation diaphragm and the sputum suction oscillation diaphragm are synchronously driven by the atomizing connecting rod and the sputum suction connecting rod to vibrate at a high frequency, so that the input gas (atomized liquid medicine) and the airflow for sucking out sputum both carry vibration waves, forming a "vibration wave superposition effect", loosening deep sputum and reducing airway mucus resistance, and also avoiding unidirectional high-pressure impact, significantly reducing the risk of mucosal damage, and at the same time improving the sputum clearance efficiency.

[0013] Further, the air supply system includes an air ventilation chamber, a transmission crankshaft, an air supply motor, an air extraction push arm, and an air supply push arm. The air ventilation chamber is arranged inside the chassis. The transmission crankshaft is rotatably arranged inside the air ventilation chamber. The air supply motor is arranged outside the air ventilation chamber. The transmission crankshaft is drivingly connected to the output end of the air supply motor. The air extraction push arm is slidably arranged inside the air ventilation chamber. An air extraction connecting rod is rotatably connected to the air extraction push arm, and the air extraction connecting rod is simultaneously rotatably connected to the transmission crankshaft. The air supply push arm is slidably arranged inside the air ventilation chamber. An air supply connecting rod is rotatably connected to the air supply push arm, and the air supply connecting rod is simultaneously rotatably connected to the transmission crankshaft.

[0014] Further, an air inlet connecting pipe and an air outlet passage are connected to the top of one end of the air ventilation chamber, and an air suction passage and an exhaust passage are connected to the top of the other end of the air ventilation chamber. Check valves are provided at the connections of the air inlet connecting pipe, the air outlet passage, the air suction passage, and the exhaust passage to the air ventilation chamber. The air inlet connecting pipe allows air to enter the air ventilation chamber unidirectionally, the air outlet passage allows air to exit the air ventilation chamber unidirectionally, the air suction passage allows air to enter the air ventilation chamber unidirectionally, and the exhaust passage allows air to exit the air ventilation chamber unidirectionally.

[0015] Further, the air intake channel is communicated with the air extraction pipeline, the air outlet channel is communicated with the atomization channel, and the humidification short pipe is communicated with the air inlet connecting pipe.

[0016] Further, the conveying channel and the right short pipe are simultaneously connected to the sputum suction channel. The sputum suction channel is composed of an atomization pipe and a sputum suction pipe. The conveying channel is communicated with the atomization pipe, and the right short pipe is communicated with the sputum suction pipe.

[0017] The beneficial effects of a sputum drainage device for thoracic surgery nursing provided by this solution are as follows: (1) To solve the problem that the existing sputum drainage devices can only perform sputum suction, a dual-channel method is adopted, an atomization mechanism and a sputum suction mechanism are set up, atomization and sputum suction are carried out simultaneously. After atomizing and moistening the airway, it can reduce the mechanical stimulation of the sputum suction tube on the respiratory mucosa, reduce the risk of bleeding or inflammation. At the same time, it can efficiently remove sputum, reduce the retention of secretions, and reduce the incidence of complications such as pulmonary infection and atelectasis. By integrating functions, it breaks through the passivity of traditional sputum suction, changing from simple clearance to an active intervention mode of "preventive softening + active clearance", which has both therapeutic and preventive effects and has important clinical significance for improving the quality of respiratory tract management; (2) A bidirectional oscillation mechanism is set up to apply high-frequency oscillation to the input and extracted intermediate gas at the same time. The generated oscillation can be transmitted to the dual-channel tube, and the oscillation is realized by using the dual-channel tube. Compared with the local high-pressure impact of single-direction vibration, the bidirectional oscillation reduces the mechanical damage to the airway mucosa by dynamically balancing the input and output pressures. Moreover, the input and extracted gases in the dual-channel tube both carry high-frequency oscillation energy, forming a "vibration wave superposition" effect, reducing airway resistance and improving alveolar ventilation; (3) An atomization mechanism is set up to atomize the liquid medicine by using the Venturi effect, realizing the whole-process management of sputum dilution, mucus loosening and efficient clearance, which has both accuracy, safety and economy.
