The half-membrane aperture is provided with a flexible membrane 111 which closes the half-membrane aperture 11, as shown in fig. 2. The middle part of the diaphragm 111 is provided with a hole, the diaphragm 111 is bonded or buckled with the semi-membrane hole 11 in the circumferential direction, and under the flexible elastic action of the diaphragm 111, the diaphragm 111 is in a closed state in a natural state, as shown in fig. 2, the diaphragm 111 is operated and moved by negative pressure, the semi-membrane hole 11 is opened in a single direction towards the inner side, as shown in fig. 3, movable sputum and other residues are attracted into the semi-membrane hole 11 under the action of gas tension in a hollow tube, after the attraction is finished, the semi-membrane hole 11 is in contact with the oral cavity wall, the gas tension disappears, the diaphragm loses attraction and automatically falls to close the semi-membrane hole 11, the semi-membrane hole 11 is closed, the residues remain in the hollow part of the joint, and the residues are effectively prevented from entering the oral cavity through the semi-membrane hole 11.

The edge of the opening part of the semi-membrane hole 11 is smooth, so that the joint is smooth when moving in the oral cavity of a patient and does not scratch the oral cavity wall of the patient. Because sputum and other residues are attached to the periphery of the oral cavity wall, a plurality of semi-membrane holes are formed and distributed at all positions on the surface of the spherical structure of the joint, so that the residues cannot be missed. With half membrane hole makes peripheral residues all can be by half membrane hole attraction into connect in, improves suction efficiency, and medical personnel is when inhaling saliva, and the operation is more convenient.

The utility model provides a saliva suction tube for an ICU, which comprises a connector with a hollow spherical structure and a hollow tubular suction tube, wherein the connector is provided with a plurality of semi-membrane holes, the hollow tubular suction tube is connected with the suction tube through the connector to form a smooth integrated piece, when the saliva suction tube for the ICU is used for sucking sputum and other residues, the smooth spherical surface is contacted with the oral cavity wall of a patient, the oral cavity wall surface is not damaged, meanwhile, under the action of negative pressure, the semi-membrane holes on the connector, which are contacted with the sputum and other residues, can be opened inwards so as to easily suck the sputum and other residues, after the suction, the semi-membrane holes are automatically closed, the semi-membrane holes contacted with the oral cavity wall are prevented from falling off, the damage to the oral cavity wall is reduced, and the suction efficiency is improved.

In order to better enable the half-membrane aperture to open when in contact with sputum and other residues and to close when in contact with the oral wall, the half-membrane aperture 11 is preferably provided with a movable membrane which enables the half-membrane aperture to be opened and closed more thoroughly. The movable membrane is connected with a small part at the edge of the semi-membrane hole, and further, the movable membrane is made of an elastic material and pulled by pulling under the condition of negative pressure, so that the movable membrane leaves the semi-membrane hole, gaps appear, and sputum and other residues are sucked into the hollow part of the joint from the gaps of the semi-membrane hole.

In order to increase the range of aspiration of sputum and other residues, in the preferred form of the utility model, semi-membrane pores 11 are arranged in an array on the surface of the connector 1. For example, the plurality of semi-membrane holes are arranged in an array to facilitate the suction efficiency when sucking residues in the oral cavity, and simultaneously facilitate the medical staff to slightly move the position when sucking, so as to ensure that the residues are not missed.

In order to connect with external equipment and better suck sputum and other residues, the joint 1 also comprises a connecting part 12 in the preferred case of the utility model, wherein the connecting part 12 is of a hollow tubular structure.

For a tighter connection with an external device, the external surface of the connecting portion 12 is preferably provided with external threads.

In order to better place the joint in the patient's mouth, in a more preferred aspect of the utility model, the saliva suction tube for an ICU further comprises a suction tube 2, said suction tube 2 comprising a hollow bent tube-like structure, said suction tube 2 being connected to said connection 12. The bending structure of the suction tube accords with human body structure, and the bending part of the suction tube can effectively press the tongue of a patient, so that the saliva suction tube stretches into the oral cavity to be more convenient to operate, the hollow part of the suction tube is larger, and sputum and other residues can be sucked out smoothly through the suction tube.

In order to better connect with other devices and ensure tightness, in a more preferable case of the utility model, one end of the suction tube 2 is of a flat structure, and the inner surface of one end is provided with internal threads. The suction tube is provided with the internal thread one end with connect the connecting portion of joint is connected, and internal and external screw thread butt joint, and exact junction can guarantee the suction effect, and tight connection makes the junction can be like integrated structure simultaneously, and seamless junction makes the saliva suction tube can not cause the injury when contacting with patient's oral cavity wall.
