Description

Sputum suction device for patients with motor neuron disease

technical field

The utility model relates to the technical field of machinery, in particular to a sputum suction device for patients with motor neuron disease.

Background technique

The most common manifestations of motor neuron disease patients are ventilator paralysis, such as slurred speech, difficulty swallowing, and difficulty expectorating sputum. Because both the inspiratory and expiratory muscles are violated, both ventilation and coughing are affected. The patient is not easy to cough up phlegm in daily life. If there is an upper respiratory tract infection, the phlegm is even more difficult to cough up, and it is easy to atrophy the lung lobes and cause pneumonia. Therefore, if a suction device can be used, the pain of the patient will be reduced, and the chance of infection of the patient will be reduced.

The sputum suction device is mainly used for routine suctioning and tracheotomy of the wounded and sick. There are many types and styles of sputum suction devices in the prior art, but the sputum suction devices on the market are mainly electric ones. Processing becomes a big problem. In addition, the sputum suction tube of the sputum suction device in the prior art is generally straight, and if the operation is careless during use, the sputum may flow back, and if the sputum returns to the patient's oral cavity, serious consequences may be caused. In view of this, we propose a suction device for patients with motor neuron disease.

A first valve is arranged between the tubes, a second valve is arranged on the right side of the upper end of the placing bottle, and a negative pressure suction ball is connected to the right side of the placing bottle through a suction pipe.

Preferably, a plurality of sputum suction holes are regularly arranged on the outer side wall of the left end of the sputum suction tube, and the sputum suction holes are elliptical.

Preferably, a rigid elbow is provided between the connecting hose and the placing bottle, the lower end of the rigid elbow is fixedly inserted into the placing bottle, and the upper end of the rigid elbow is fixed It is sleeved on the outer side wall of the right end of the connecting hose.

Preferably, a negative pressure drain is also provided outside the bottle, the bottom end of the negative pressure drain is provided with a pull handle, and the port of the negative pressure drain is connected with the right end of the suction tube through a thread.

Preferably, the left end of the first valve is fixedly clamped in the suction pipe, the right end of the first valve is fixedly clamped in the connecting hose, and the flow direction of the first valve is from left to right.
