Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a ventilator device with auxiliary sputum suction function. Background Art

[0002] A ventilator is a vital medical device for preventing and treating respiratory failure, reducing complications, saving and prolonging the life of patients. It is a commonly used assisted breathing device in hospitals. When patients cannot breathe independently or have severe respiratory failure, in order to buy time for treatment, a ventilator must be used to help patients breathe normally, ventilate and maintain life. In this process, the cause of the disease is actively treated, and after the patient recovers, the lung function can slowly return to normal, and the ventilator can be released. In the prior art, a three-way tube connected to a suction tube is provided at the outer end of the breathing duct leading to the patient's airway from the ventilator. The purpose is to perform suction operation for the patient during assisted breathing. The disadvantage is that the breathing circuit needs to be temporarily disconnected. During this process, the patient needs to be separated from the ventilator for oxygen supply for at least 30 seconds to 1 minute. This operation can easily lead to a decrease in the patient's blood oxygen level. In addition, the operation usually requires two people to collaborate to complete, which is time-consuming and labor-intensive, and there is a risk of passive infection of medical staff; the closed suction tube on the market currently has a fixed model, complex operation, and is prone to the risk of suffocation of patients due to wrong operation, and there are disadvantages of repeated use and high price.

At the same time, the ventilator pipeline is sealed throughout the whole process, and there is no aerosol to cause passive infection of medical staff.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a ventilator device with auxiliary sputum suction function, including a ventilator, a breathing circuit, a spare port cap, a three-way pipe, a negative pressure pump and a sputum guiding tube, and also including a pipe joint, an artificial airway and a sputum suction tube. A through hole is provided on the outer wall of the left part of the pipe joint, the left end of the pipe joint is connected with the right end of the three-way pipe, the left end of the artificial airway is connected with the right end of the pipe joint, the right end of the sputum suction tube is inserted into the artificial airway through the through hole and extends to the outside of the right end of the artificial airway, and the left port of the sputum suction tube extends outside the through hole and is connected with the inlet of the negative pressure pump.

[0005] The above-mentioned ventilator device with auxiliary sputum suction function, the pipe joint is provided with an annular boss on the outer periphery of the middle part, the inner diameter of the tube on the left part of the annular boss is larger than the inner diameter of the tube on the right part of the annular boss, the through hole is located on the tube wall on the left part of the annular boss, and a sealing sleeve is provided on the outer wall of the artificial airway outside the through hole, which is connected and wraps the sputum suction tube.

[0006] The above-mentioned ventilator device with auxiliary sputum suction function also includes a valve and a sputum suction tube. The lower port of the valve is connected to the inlet of the negative pressure pump through a pipeline, and the upper port of the valve is connected to the left port of the sputum suction tube through the sputum suction tube.

[0007] The above-mentioned ventilator device with auxiliary sputum suction function also includes a butt joint pipe, which is sleeved between the left port of the sputum suction tube and the sputum guiding tube.

[0008] The utility model provides a ventilator device with auxiliary sputum suction function, which includes a ventilator, a breathing circuit, a spare mouth cap, a three-way pipe, a negative pressure pump and a sputum guiding tube, and also includes a pipe joint, an artificial airway and a sputum suction tube. A through hole is provided on the outer wall of the left part of the pipe joint, the left end of the pipe joint is connected with the right end of the three-way pipe, the left end of the artificial airway is connected with the right end of the pipe joint, the right end of the sputum suction tube is inserted into the artificial airway through the through hole and extends to the outside of the right end of the artificial airway, and the left port of the sputum suction tube extends outside the through hole and is connected with the inlet of the negative pressure pump.

[0009] The beneficial technical effects of the utility model are as follows: First, the right end of the sputum suction tube is inserted into the artificial airway through the through hole and extends to the outside of the right end of the artificial airway, and the left port of the sputum suction tube extends outside the through hole and is connected to the inlet of the negative pressure pump. This structure can ensure that the patient is ventilated while suctioning the sputum for the patient without disconnecting the artificial airway, thus avoiding the phenomenon of hypoxia when the patient is separated from the ventilator. Second, a sealing sleeve that is connected and wraps the sputum suction tube is provided on the outer wall of the artificial airway, which ensures the sealing of the periphery of the sputum suction tube and prevents the leakage of the artificial airway from generating aerosols and causing passive infection of medical staff. Third, the installation of the valve facilitates the sputum suction operation of the negative pressure pump, which can be completed independently by one person, shortening the operation time and reducing labor costs. Fourth, the butt-joint pipe sleeve is installed between the left port of the sputum suction tube and the sputum induction tube, which facilitates the docking of the sputum suction tube and the sputum induction tube, has a dust-proof and antibacterial effect on the sputum suction tube mouth, and reduces the occurrence of cross-infection in patients. The utility model has a simple structure and is easy to use, simplifies the steps of ventilator-assisted ventilation and sputum suction operation, and has the characteristics of improving the operating efficiency of medical staff.
