Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail. Embodiment of the present utility model includes but not limited to the following example.

Embodiment

As shown in Figure 1, 2, the present embodiment provides a kind of radiotherapy suction type tongue depressor, this tongue depressor is mainly made up of two parts: the coated chamber of tongue and external control chamber, wherein, the coated chamber of tongue is used for placing tongue, by regulating the pressure size in external control chamber, change mechanical pressure and the gas pressure in the coated chamber of tongue, tongue is pressed and wraps. The large I in the coated chamber of tongue arranges different model, but must can put into patient's face, is shaped as flattened oval body, and shape, the size in external control chamber are not particularly limited, but should be as the criterion with handled easily. The coated chamber of tongue and external control chamber all can adopt the rubber of soft materials to form, and are convenient to pressing operation on the one hand, on the other hand, can avoid the damage to human body.

The coated chamber of tongue should have opening, so that the placement of tongue, the opening and closing of the coated chamber of tongue opening realize by peripheral control unit. In the present embodiment, the realization that tongue is adsorbed in the coated chamber of tongue under the effect of negative pressure forms based on middle part gaseous core and outside gaseous core, specifically, external control chamber is the stereochemical structure of an inner hollow, outside gaseous core is arranged on its end face, opening of outside gaseous core can be realized by extruding external control chamber, the air in external control chamber can be discharged thus; External control chamber is connected with the coated chamber of tongue, middle part gaseous core is arranged on the junction of the two, in the time that middle part gaseous core is closed, the coated chamber of external control chamber and tongue is relatively independent, not identical between the two, in outside control chamber after Bas Discharged, unclamp external control chamber, now, middle part gaseous core is opened, and starting has air in the coated chamber of tongue, and in external control chamber, do not have air, therefore under the effect of negative pressure, air can flow in external control chamber in the coated chamber of tongue, thereby make the coated chamber of tongue adsorb gradually tongue.

In the present embodiment, the coated cavity configuration of the tongue of employing and external control cavity configuration are as follows respectively:

The coated chamber of tongue is flattened oval body, and it comprises the tongue coating cavity that is made up of rubber membrane and the first support that can opening and closing; Described the first support have upper and lower two can opening and closing pressure plate, its for push down tongue state tongue coating cavity under suction function for holding tongue.
