Example 1

As shown in fig. 1 to 3, the dental pad for an edentulous patient comprises a dental pad base 101 disposed between upper and lower gingiva, wherein: the tooth pad seat 101 is in a straight-line structure, the setting direction of the tooth pad seat is the same as the setting direction of upper gum and lower gum, a first clamping block 102 matched with the inner wall of the lower gum is convexly arranged at the inner side of the tooth pad seat 101 close to the lower gum, an air pipe hole into which an air supply pipe 104 is inserted and a discharge hole into which a discharge pipe 105 for discharging secretion in oral cavity and nasal cavity is inserted are arranged on the tooth pad seat 101, and a tightening component for tightly attaching a second clamping block 107 to the outer side face of the lower lip is arranged on the discharge pipe 105.

Preferably, the discharge tube 105 and the discharge hole, the air tube 104 and the air tube hole are matched in size and shape, and the outer diameters of the discharge tube 105 and the air tube 104 are preferably slightly larger than the corresponding discharge hole and air tube hole, so that the discharge tube 105 and the air tube 104 are tightly arranged on the corresponding discharge hole and air tube hole.

Specifically, the tightening assembly comprises a tightening external thread 108 disposed on the discharge pipe 105 and located on the outer side of the oral cavity, and a tightening knob 109 sleeved on the discharge pipe 105 and connected with the tightening external thread 108 in a threaded manner, wherein the tightening knob 109 is connected with the second clamping block 107.

Preferably, the side of the dental pad 101 which is attached to the upper and lower gingiva is provided with a plurality of tooth-like protrusions 112 which are engaged with the tooth grooves in the upper and lower gingiva, respectively, and further, the tooth-like protrusions 112 are made of silicone rubber and provided with a plurality of anti-slip threads.

In use, the serrated nose 112 engages with the indentations in the upper and lower gingiva to increase the contact surface and thereby further improve the bonding strength between the bite block 101 and the upper and lower gingiva.

Preferably, the bite block base 101, the first holding block 102 and the second holding block 107 are made of medical soft materials, so that the bite block base 101, the first holding block 102 and the second holding block 107 can be better attached to the oral cavity, the attaching area is increased, and the bonding strength between the bite block base and the oral cavity is improved.

The medical soft material can be, but is not limited to, medical silica gel, flexible medical resin material and the like.

Example 2

This embodiment is substantially the same as embodiment 1 except that: the tightening assembly further includes a sleeve 110 disposed on the air tube 104, the sleeve 110 is connected to the second clamping block 107, and preferably, an axial notch 111 for inserting the air tube 104 is formed on one side of the sleeve 110 along the axial direction.

In use, the air tube 104 can be conveniently inserted into the sleeve 110 through the axial slit 111 formed in the sleeve 110, and due to the arrangement of the sleeve 110, another supporting point is added to the second holding block 107, so that the second holding block can be better matched with the outer side of the lower lip.
