The mattress 2 is provided with a vibration device. When working, the vibration device can drive the patient's chest to vibrate, so that the sputum in the patient's trachea or bronchus falls off to speed up expectoration. In this embodiment, as shown in Figure 5, the vibration device is mainly composed of a vibration airbag 7 and an air vibrator. The vibration airbag 7 is arranged in the cushion body 2.1, and the air vibrator is installed in the bed frame 1 [the installation position of the air vibrator can be flexibly set according to the specific situation of the product, which is not limited here]. The vibration airbag 7 is connected to the air vibrator through the trachea. In this way, the air vibration generated by the air vibrator when working can be transmitted to the vibration airbag 7 through the trachea, so that the air in the vibration airbag 7 also oscillates, thereby playing a gentle tapping vibration role on the patient's chest and back, so as to facilitate the patient's expectoration. The air vibrator can adopt a conventional product in the prior art or be transferred from an existing design [CN201110046227.6, air vibration expectoration instrument].

As shown in FIG3 , the central part of the mattress 2 near the head end is provided with a face placement hole 2.2 for placing the human face, so as to meet the placement of the face of the patient when lying prone. In this embodiment, the face placement hole 2.2 is located between the first cushion body 2.1a and the second cushion body 2.1b, and a first pipeline placement groove 2.3 is provided between the first cushion body 2.1a and the second cushion body 2.1b, the inner end of the first pipeline placement groove 2.3 is connected to the face placement hole 2.2, and the first pipeline placement groove 2.3 is equipped with a detachable filling strip 2.4. By providing the first pipeline placement groove 2.3, when the patient has an air breathing tube, the first pipeline placement groove 2.3 can be used as a tube passage for the air breathing tube; if the first pipeline placement groove 2.3 is not needed, the first pipeline placement groove 2.3 can be filled and leveled with a filling strip 2.4 to improve the comfort of use. Generally speaking, the first pipeline placement groove 2.3 should be set at more than 20 cm so that the air breathing tube has a long enough placement space to avoid being pressed by the patient's head.

As shown in FIG3 , in this embodiment, the face placement hole 2.2 is an ellipse, which can be adapted to the human face shape and make the patient comfortable. In actual production applications, the face placement hole 2.2 can also be set to a melon seed shape that matches the human face shape, and the size of the face placement hole 2.2 near the head end is larger than the size at the other end, which is more adapted to the human face shape.

In addition, a detachable filling block or facial gasket may be provided in the facial placement hole 2.2. By providing a filling block, when the patient does not need to lie prone, the facial placement hole 2.2 can be filled and leveled with the filling block, thereby improving the comfort of use. By providing a soft facial gasket, the comfort of use of the patient can be greatly improved; and since the facial gasket is detachable, the facial gasket of corresponding specifications can be replaced according to the actual situation of the patient, thereby further improving the comfort of use of the patient.

As shown in Fig. 2 and Fig. 3, two second pipeline accommodating grooves 2.5 are provided in the middle area of the mattress 2, the inner ends of the two second pipeline accommodating grooves 2.5 are opposite, and the outer ends are respectively connected to the two side surfaces of the mattress 2; a detachable filling strip 2.4 is arranged in the second pipeline accommodating groove 2.5.

In this embodiment, one of the two second pipeline placement grooves 2.5 is located on the third pad body 2.1c, and the other is located on the fourth pad body 2.1d, which is more compatible with the position of the patient's tube and can meet the actual use. In actual production, considering that the size of the entire drainage and sputum bed may be designed differently, the positions of the two second pipeline placement grooves 2.5 can also be flexibly adjusted, such as one is located on the fifth pad body 2.1e and the other is located on the sixth pad body 2.1f; or one is located between the third pad body 2.1c and the fifth pad body 2.1e, and the other is located between the fourth pad body 2.1d and the sixth pad body 2.1f.

In the present invention, the inner diameters of the first pipeline placement groove 2.3 and the second pipeline placement groove 2.5 are generally set to 3 cm, which is sufficient to meet the needs of existing air breathing tubes and other medical pipeline routing. Of course, for medical pipelines of special sizes, the first pipeline placement groove 2.3 and the second pipeline placement groove 2.5 can also be flexibly set. Generally speaking, avoiding squeezing of the pipeline is the first principle.

As shown in Figures 1 and 2, in this embodiment, the mattress 2 is provided with a buffer support pad 2.6 and an anti-slip restraint belt 2.7. The buffer support pad 2.6 corresponds to the joints of the human body, and the anti-slip restraint belt 2.7 includes a shoulder restraint belt 2.7.1, a hip restraint belt 2.7.2 and an ankle restraint belt 2.7.3. The buffer support pad 2.6 should have a certain thickness. When the patient lies down, the relevant position with large joint contact pressure is located on the buffer support pad 2.6, so that the joint pressure when the patient lies down can be buffered to ensure comfort. The restraint belt 2.7 can provide restraint for the patient's limbs [including the shoulders, hips, and ankles] to prevent the patient from sliding during treatment. In the present invention, the buffer support pad 2.6 is preferably made of silicone to ensure its softness; the restraint belt 2.7 is preferably made of nylon to ensure its firmness.

The above description is only a preferred embodiment of the present invention, and the above specific embodiment is not a limitation of the present invention. Various deformations and modifications may occur within the scope of the technical concept of the present invention, and any modification, modification or equivalent replacement made by ordinary technicians in the field according to the above description belongs to the scope of protection of the present invention.
