As shown in fig. 1, the device for accommodating a dam of the present invention may include a bag body 1 for accommodating a dam drooping and scattering when no face bow acts on the dam and collecting secretions on the dam; the fixing component 2 is used for sleeving the bag body 1 on the rubber dam or removing the bag body 1 from the rubber dam after collection is finished.

Optionally, the mouth of the bag 1 is connected with the split ring 6 of the fixing assembly 2, so that the mouth is always in an open state. Preferably, the pockets can be provided on the split ring 6 by gluing, winding or integral generation. The shape of the split ring 6 is not or not easily changed. The material of split ring 6 may be a combination of one or more of aluminum, iron, copper, etc. The circumference of the open ring 6 is provided with a second passage opening 7 which penetrates to the inner wall. The second opening 7 is passed through by the band strip 41 of the elastic band 4.

Optionally, the fixation assembly 2 further comprises a collar 3. The collar 3 is provided with a hollow structure inside to accommodate the strap 41 therethrough. The surrounding side of the lantern ring 3 is provided with a first passage opening 5 which penetrates through the inner wall and is used for the band strip 41 to pass through. The first passage opening 5 is positioned in correspondence with the second passage opening 7. Preferably, the straight line in which the first passage opening 5 and the second passage opening 7 are located passes through the center of the open ring 6. The strap 41 can be threaded through the first passage 5 a round into the hollow structure of the collar 2 and then out through the first passage opening 5. The band-passing portion is passed through the locking portion 42 of the elastic band 4 and the second passage opening 7 in this order, wherein the locking portion 42 is arranged on the collar circumference side near the first passage opening 5. The shape and size of the collar 3 may be varied based on the length of the band 41 to achieve securement or release of a dam through the collar 3. The locking portion 42 is connected to the first passage opening 5 and is displaced based on the deformation of the collar 3. Preferably, the collar 3 is made of medical plastics such as PVC polyvinyl chloride, PVC polyvinyl chloride and PC polycarbonate, which are relatively flexible materials.

Optionally, the collar 3 is circumferentially provided with a number of annular arrays of connecting strips 8 for connecting the collar 3 and the split ring 6. The connecting bar 8 has one end connected to the inner wall of the split ring 6 and the other end connected to the peripheral side of the collar 3. The connecting strip 8 is composed of rubber having elastic deformability. Preferably, the connecting strip 8 may also be a spring structure composed of a metal having elastic deformation capability, such as phosphor bronze, beryllium bronze, manganese steel or stainless steel. The connecting strip 8 can be extended when the collar 3 is retracted or retracted when the collar 3 is extended so that the collar 3 is always connected to the split ring 6. The lantern ring 3 and the split ring 6 are not completely connected in a closed mode through the connecting strip 8, so that the hollow part between the lantern ring 3 and the split ring 6 can be used for enabling secretion on the rubber dam to flow into the bag body 1.

Optionally, the bottom end of the bag body 1 is provided with a pressing sheet 9, so that the bag body 1 is kept in a vertical downward state to help secretion on the rubber dam to flow into the bag body 1 and collect. Preferably, the tab 9 is placed directly inside the pouch 1 to prevent the pouch 1 from flying based on its own weight.

Alternatively, the elastic tie 4 in the present application may be an elastic nylon tie proposed in the prior art CN201921395984.2 (which is incorporated herein in its entirety for ease of understanding). For the convenience of description, the nylon elastic band is divided into the band 41 and the locking portion 42, and the length of the band 41 in the collar 3 can be adjusted by changing the operation mode of the locking portion 42.

The utility model discloses a use method as follows: adjusting the locking portion 42 of the elastic band 4 to the tightening mode pulls the band strip 41 outside the second opening 7 through the collar 3 in the loose state to tighten the elastic band 4, reducing the length of the band strip 41 inside the collar 3 so that the collar 3 contracts to secure the dam in the band. Secretions from the surface of the dam can fall into the bag body 1 from between the collar 3 and the split ring 6. When the device is to be removed, the locking portion 42 is adjusted to a release mode, the band 41 outside the second opening 7 is pushed to release the elastic band 4, and the length of the band 41 in the loop 3 is increased to extend the loop 3 to release the dam, so that the bag body 1 can be removed from the dam.
