Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a device for quickly and accurately mixing and dispensing powder and liquid oral dental medical materials. Background Art

[0002] At present, some materials used in oral dentistry are mostly mixed by mixing powder and liquid materials in a certain proportion on mixing paper with a mixing stick before use. However, in order to prevent moisture and deterioration, these materials are generally stored in sealed powder packaging bottles and liquid packaging bottles. When mixing materials, medical staff need to open each bottle and use the spoon equipped to take powder and liquid. The water-to-powder ratio obtained by taking powder and liquid with the spoon is not accurate enough. After taking powder and liquid, they need to be mixed on mixing paper. Mixing paper is often separated from drugs and is easy to miss before mixing, resulting in the need to walk back and forth to get mixing paper, which reduces work efficiency. Therefore, the existing method of mixing powder and liquid materials has the problem that it is inconvenient for medical staff to take powder and liquid when mixing materials, and it takes a long time to take powder and liquid, which affects work efficiency. In addition, the water-to-powder ratio is not accurate. Powder or liquid needs to be added repeatedly according to the properties of the material during mixing, resulting in a problem of too long mixing time. On the other hand, an inaccurate water-to-powder ratio will also cause the material to be too viscous or too hard after mixing, thereby affecting the filling and bonding effects of the material.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Figure 1 The oral material mixing device comprises a mixing table 1, a mixing knife 9, a mixing paper 10, a powder discharging device 2, a powder containing box 3, a liquid containing box 6 and a liquid discharging device 7.

[0022] The mixing table 1 is a rectangular frame, in which a mixing paper 10 is placed, and on the frame is a movable mixing board. When mixing oral materials, a mixing paper 10 is taken out from the frame, the movable mixing board is laid flat, and then the taken mixing paper 10 is placed on the movable mixing board for mixing. A mixing knife sheath 8 is provided at the front end of the mixing table 1, and a mixing knife 9 is sheathed in the mixing knife sheath 8 when not in use; a powder discharge device 2 and a liquid discharge device 7 are arranged side by side at the rear end of the mixing table 1; a powder box 3 and a liquid box 6 are connected above the powder discharge device 2 and the liquid discharge device 7 respectively; a powder box cover 4 and a liquid box cover 5 are provided at the upper ends of the powder box 3 and the liquid box 6 respectively.

[0023] like Figure 2 As shown, the powder discharging device 2 includes a powder discharging button 2-1, a powder discharging port 2-2, a powder inlet 2-3, a slider 2-4, a connecting hole 2-5, a powder discharging channel 2-6, a chute 2-7 and a powder discharging regulating spring 2-8.

[0024] The slider 2-4 can slide in the slide groove 2-7, one end of the slider 2-4 is connected to the powder discharge adjusting spring 2-8, and the other end is connected to the powder discharge button 2-1. A through powder hole, namely a connecting hole 2-5, is provided in the slider 2-4. When the powder discharge button 2-1 is in the original position without pressing the powder discharge button 2-1, the upper part of the connecting hole 2-5 is connected to the powder inlet 2-3, and the lower part is closed to the powder discharge channel 2-6. At this time, the powder enters the connecting hole 2-5 and fills the connecting hole 2-5. When the powder discharge button 2-1 is pressed into place, the upper part of the connecting hole 2-5 is closed to the powder inlet 2-3, and the lower part is connected to the powder discharge channel 2-6. At this time, all the powder in the connecting hole 2-5 falls into the powder discharge channel 2-6 and slides out from the powder discharge port 2-2 to the mixing paper placed on the mixing table 1. When the powder discharge button 2-1 is released, the slider 2-4 is reset under the action of the powder discharge adjusting spring 2-8. The weight of the powder filled in the volume of the communicating hole 2-5 is the weight of the powder discharged at one time. By designing different volumes of the communicating holes 2-5, different powder discharge amounts can be obtained at one time.

[0025] In order to make the powder in the powder outlet channel 2-6 slide out smoothly from the powder outlet 2-2, the powder outlet channel 2-6 is formed into an inclined channel. The powder inlet 2-3 is connected to the outlet at the bottom of the powder box 3. In order to make the powder in the powder box 3 smoothly enter the powder inlet 2-3 of the powder outlet device 2, the outlet of the powder box 3 is set to be funnel-shaped (not shown in the figure).

[0026] Figure 3 As shown, the liquid outlet device 7 includes a liquid outlet button 7-1, a liquid outlet 7-2, a liquid inlet 7-3, a liquid outlet regulating spring 7-4, a linkage rod 7-5, a liquid storage bag 7-6, a valve 7-7 and a check valve 7-8.

[0027] One side of the liquid storage capsule 7-6 is connected with the liquid inlet 7-3 through the check valve 7-8, and the other side is pressed by the pressure block at the front end of the liquid discharge regulating spring 7-4, and the lower part is connected with the liquid outlet 7-2 through the valve 7-7; the other end of the regulating spring 7-4 is connected with the liquid discharge button 7-1 and the linkage rod 7-5, and the other end of the linkage rod 7-5 is connected with the opening and closing rod of the valve 7-7, and as the liquid discharge button 7-1 and the regulating spring 7-4 move back and forth, they are linked to open or close the valve 7-7 at the same time; when the liquid storage capsule 7-6 is full of liquid, the liquid discharge button 7-1 is pressed, and the pressure block in front of the liquid discharge regulating spring 7-4 squeezes the liquid storage capsule 7-6, at this time, the check valve 7-8 is closed, and at the same time, the valve 7-7 is opened under the action of the linkage rod 7-5, and the liquid is squeezed out from the liquid outlet 7-2. Release the liquid discharge button 7-1, and the liquid discharge button 7-1 returns to its original position under the action of the liquid discharge regulating spring 7-4. At the same time, since there is negative pressure in the liquid storage capsule 7-6 at this time, the check valve 7-8 opens when the liquid storage capsule 7-6 returns to its original position, and the check valve 7-8 closes after the liquid refills the liquid storage capsule 7-6; when the liquid discharge regulating spring 7-4 returns to its original position, the linkage rod 7-5 is driven to close the valve 7-7, and the liquid enters the next cycle after the liquid fills the liquid storage capsule 7-6. The weight of the liquid filled in the volume of the liquid storage capsule 7-6 is the weight of the liquid discharged at one time. By using liquid storage capsules 7-6 with different volumes, different liquid discharge amounts can be obtained at one time.

[0028] In order to make the liquid in the liquid outlet channel flow out smoothly from the liquid outlet 7-2, the liquid outlet channel is also made into an inclined channel. The liquid inlet 7-3 is connected to the outlet at the bottom of the liquid storage box 6. In order to make the liquid in the liquid storage box 6 smoothly enter the liquid inlet 7-3 of the liquid outlet device 7, the outlet of the liquid storage box 6 can also be set to a funnel shape (not shown in the figure).

[0029] The total length of the mixing table 1 is 85 mm, the width is 75 mm, and the thickness is 10 mm; the total length of the powder discharge device 2, the liquid discharge device 7, the liquid box 6, and the powder box 2 are all 35 mm and 35 mm wide; for other dimensions, see Figure 1 .

[0030] like Figure 4 As shown, in order to facilitate placement and avoid contamination when not in use, the rear end of the mixing table 1 can be hinged to the base of the powder outlet device 2 and the liquid outlet device 7. When not in use, the mixing table 1 is folded to the front side of the liquid box 6 and the powder box 2, and the powder outlet 2-2 and the liquid outlet 7-2 are covered.

[0031] Before mixing the materials, the medical staff first opens the mixing table, then adjusts the powder-liquid ratio on the proportion adjustment panel as needed, presses the powder and liquid discharge buttons, and the powder and liquid flow directly onto the mixing table. The medical staff mixes the materials directly on the mixing table without the need to take out additional mixing paper. Because the materials have been taken out according to the proportion, the medical staff does not need to add additional powder or liquid during mixing, which saves time in taking powder, liquid and mixing. It is convenient, fast and time-saving, can effectively improve work efficiency, reduce the occurrence of repeated powder and liquid taking, and can also effectively reduce the impact on the materials caused by incorrect water-powder ratio and excessive mixing time.
