[0002] Dental isolation membranes are protective materials used to prevent cross-infection, and are usually supplied in roll form. The membrane itself has perforations at regular intervals, allowing it to be torn to the appropriate length as needed. The main purpose of the isolation membrane is to be applied to areas on the dental chair that the dentist may touch (such as armrests and operating panels) to prevent contamination of the dentist's gloves during procedures, thereby reducing the risk of cross-infection.
[0003] There are currently two issues regarding its usability: Easily contaminated after opening: After the isolation film is opened, the entire roll of dental isolation film is exposed to the outside. The exposed surface and sides are easily exposed to other equipment or pollutants in the hospital environment, which can lead to contamination of the film surface and affect the protective effect.
[0004] Inconvenient operation: When applying the isolation film, doctors usually need to wear gloves on both hands, which not only increases the complexity of the operation, but may also affect the accuracy and efficiency of the application due to the limited flexibility of the gloves.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] like Figure 1 and Figure 3 As shown, this utility model discloses a portable dental isolation film storage and usage device, comprising: The housing 1 is used to store and release the dental isolation film 4. The dental isolation film 4 is in a closed environment inside the housing 1. The housing 1 has an isolation film outlet 11. The dental isolation film 4 is led out from the isolation film outlet 11. In the relatively closed environment of the housing 1, the unfolded front part and the rolled-up side part of the dental isolation film 4 are protected, cutting off its contact with the external environment and preventing external stains and bacteria from adhering to the dental isolation film 4, thus ensuring the hygiene of the dental isolation film 4.
[0020] The cut-off mechanism 2 has a separation membrane outlet 11 on the housing 1. The dental separation membrane 4 is pulled out from the separation membrane outlet 11 for use. The cut-off mechanism 2 is located at the separation membrane outlet 11 of the housing 1. The dental separation membrane 4 at the cut-off mechanism 2 is easily separated from the dental separation membrane 4 outside the housing 1 by clamping the dental separation membrane 4 at the cut-off mechanism 2. Specifically, it includes a first stop bar 21 fixed inside the isolation membrane outlet 11 and a second stop bar 22 that is movable relative to it. The dental isolation membrane 4 is pulled out and passes between the first stop bar 21 and the second stop bar 22. As the first stop bar 21 and the second stop bar 22 clamp each other, the dental isolation membrane 4, which is outside the housing 1, is pulled and can be disconnected near the stop mechanism 2, so as to facilitate the use of the dental isolation membrane 4.
[0021] The control mechanism includes a grip 31, a push rod 32, a spring 33, and a trigger 34. The grip 31 is fixed to the outside of the housing 1. The push rod 32 is located inside the housing 1. One end of the push rod 32 is connected to the second stop bar 22, and the other end is connected to the inner wall of the housing 1 through the spring 33. The push rod 32 and the spring 33 are arranged along the direction of relative clamping movement of the first stop bar 21 and the second stop bar 22. The surface of the second stop bar 22 is provided with textures to increase friction. The trigger 34 passes through the housing 1 and is fixed to the push rod 32 through a connector.
[0022] In use, hold the handle 31 and pull the trigger 34 to move the push rod 32 away from the isolation membrane outlet 11, compressing the spring 33. This causes the second stop bar 22 to move away from the first stop bar 21, and the clamping between the first stop bar 21 and the second stop bar 22 is released, allowing the dental isolation membrane 4 to be continuously pulled out. When it is necessary to cut the dental isolation membrane 4, release the trigger 34, the spring 33 releases its compression force, and pushes the push rod 32 to achieve mutual clamping between the first stop bar 21 and the second stop bar 22, thus clamping the dental isolation membrane 4. The dentist can then grasp the dental isolation membrane 4 outside the housing 1 and pull it to break it at the appropriate continuous perforation point. It is not necessary to wear gloves on both hands during operation, as the hand holding the housing 1 is freed up to perform other operations, improving the user experience. Example 1
[0023] The housing 1 of this utility model includes a lower housing 12 and an upper housing 13, which form an installation cavity. The installation cavity is provided with an installation mechanism 5 and a cut-off mechanism 2. The installation mechanism 5 is used to install the isolation membrane, and the cut-off mechanism 2 is used to control the length of the isolation membrane pulled out. Specifically, such as Figure 3 As shown, the lower housing 12 has a groove-shaped structure, and the upper housing 13 is a cover that matches the shape of the lower housing 12; the lower housing 12 includes a straight groove edge 14, the isolation membrane outlet 11 is located at the end of the straight groove edge 14, and the push rod 32 and the spring 33 are arranged along the straight groove edge 14.
[0024] In this embodiment, the lower housing 12 is provided with a limiting component at the straight groove edge 14 to keep the push rod 32 moving in a straight axial direction. Under the limitation of the limiting component, the push rod 32 can only move in the front and back directions, which ensures the clamping stability of the first stop bar 21 and the second stop bar 22.
[0025] In addition, the trigger 34 and the push rod 32 are fixed by a connector. The lower housing 12 has a strip hole on the straight groove edge 14 for the connector of the trigger 34 to move. The connector moves back and forth along the strip hole. The design length of the strip hole is determined according to the needs. It should be noted that the smaller the length of the strip hole, the easier it is to prevent external bacteria from entering.
[0026] In this embodiment, the connector for the trigger 34 is connected to the middle area of the push rod 32; the grip 31 is connected to the outside of the straight groove edge 14 near the spring 33 area. The positional design of the trigger 34 and the grip 31 can ensure smooth operation. Example 2
[0027] Based on Embodiment 1, the installation mechanism 5 of the separator includes a spindle 51, a sleeve 52 and a nut 53; the sleeve 52 is used to rotate with the separator, and the spindle 51 and the sleeve 52 are also rotated together. The lower housing 12 and the upper housing 13 are both provided with through holes, and the through holes are coaxial when the upper housing and the lower housing are engaged.
[0028] Specifically, the mandrel 51 passes through the lower housing 12 and the upper housing 13. The nut 53 is threaded to the end of the mandrel 51 and is used for the installation and fixation of the lower housing 12 and the upper housing 13. When replacing the dental isolation membrane 4, remove the nut 53, open the upper housing 13, replace the dental isolation membrane 4, close the upper housing 13, and tighten the nut 53. The sleeve 52 is fitted onto the spindle 51 inside the housing 1 and is in a rotating state relative to the spindle 51. The dental isolation membrane 4 is fitted onto the sleeve 52 and rotates continuously. The size of the sleeve 52 is set according to the specifications of the dental isolation membrane 4, and the thickness of the housing 1 is also set according to the specifications of the dental isolation membrane 4. Example 3
[0029] The end of the isolation membrane outlet 11 is also equipped with a roller 6. The two ends of the roller 6 are brackets fixed to the housing 1. When the doctor attaches the torn dental isolation membrane 4 to the parts of the dental chair that the doctor may touch, such as the armrest or the control panel, there is no need to press the dental isolation membrane 4 with your hand. You can simply hold the housing 1 and roll it repeatedly on the dental isolation membrane 4 with the roller 6 to press it firmly, thus reducing direct contact between the hand and the equipment.
[0030] In this embodiment, the bottom of the lower housing 12 is provided with a steering shaft 7, which is perpendicular to the lead-out direction of the dental isolation membrane 4 and is used to help transport the dental isolation membrane 4 to the outlet.
[0031] In this embodiment, a pad 8 is provided at the bottom of the lower housing 12. The pad 8 is perpendicular to the lead-out direction of the dental isolation membrane 4 and is used to remove wrinkles of the dental isolation membrane 4 during the transportation process.
[0032] It should be noted that the non-adhesive surface of the dental isolation membrane 4 contacts the steering shaft 7 and the pad 8, thereby sliding on the steering shaft 7 and the pad 8, which facilitates continuous extraction.
[0033] In this invention, the shell 1 can be semi-circular, a near-right-angled triangle structure, or a rectangle. Preferably, the shell 1 has a near-right-angled triangle structure, with the long straight side of the right-angled triangle structure being a straight groove side 14.
[0034] When this utility model is in use, the isolation film can be torn apart by pulling when the first stop bar 21 and the second stop bar 22 clamp it. When the trigger block is pulled, the isolation film can be pulled out and pasted to the desired position. This design not only facilitates the use process, but also ensures the hygiene of the isolation film storage environment.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
