Problems solved by technology

In actual operation, the extruded medicine is in the form of a paste, and the medicine is extruded into a strip shape, and the diameters of each part of the strip medicine are different. It is easy to make errors in judging the volume of the medicine manually, resulting in mixing after proportioning. There is an error in the proportion of the medicine, which is not conducive to root canal treatment

Embodiment 1

[0032] Dispensing devices for root canals, such as figure 1 As shown, it includes a bracket 1, a mixing bucket 2 and a measuring bucket 3. The measuring bucket 3 is welded on the bottom of the mixing bucket 2 and communicated with the bottom of the mixing bucket 2, and the mixing bucket 2 is coaxial with the measuring bucket 3. The measuring bucket in this embodiment The outer diameter and inner diameter of 3 are smaller than the outer diameter and inner diameter of the mixing tank 2 respectively, and an annular limit ring 1 is welded on the bracket, the lower end of the measuring tank 3 is located in the limit ring 1, and the bottom of the mixing tank 2 is located in the limit ring 1, the limit ring 1 supports the mixing bucket 2 and the measuring bucket 3.

[0033] The bracket is fixed with a first driving part by bolts. The first driving part in this embodiment adopts a forward and reverse motor. The outer wall of the mixing bucket 2 is fixed with a ring gear 21 through a s...

Embodiment 2

[0043] On the basis of Example 1, such as figure 2 As shown, the mixing tank 2 in this embodiment is provided with an annular retaining ring 6 , and the outer wall of the retaining ring 6 is in close contact with the inner wall of the mixing tank 2 . The left and right sides of the retaining ring 6 are respectively provided with a lower pressing rod 51 and a guide rod, and the lower ends of the lower pressing rod 51 and the guiding rod are all welded on the retaining ring 6 . The upper end of the guide rod runs through the support, and a lower pressing assembly is arranged above the lower pressing rod 51 .

[0044] The pressing assembly includes a spring, a cam 5 and a second driving member. The second driving member in this embodiment adopts a motor, and the second driving member is fixed on the bracket by bolts. The output shaft of the second driving member is connected with the cam 5 through a spline, and the cam 5 is opposite to the top of the lower pressing rod 51 . The ...

Abstract

The invention relates to the field of medical auxiliary instruments, in particular to a medicine dispensing device for root canals. It includes a fixedly connected mixing bucket and a measuring bucket. The measuring bucket is located under the mixing bucket and communicates with the bottom of the mixing bucket. There is a piston sliding and sealed in the measuring bucket, and a measuring rod is fixed at the bottom of the piston. The lower end of the measuring rod penetrates the bottom of the measuring bucket and slides with the measuring bucket connection; the stirring barrel is provided with a stirring shaft, and the stirring barrel is connected with a first driving member for driving the stirring barrel to rotate. The medicine dispensing device for the root canal of the present invention can extrude medicine in proportion to reduce manual judgment and thus reduce errors.

Description

technical field [0001] The invention relates to the field of medical auxiliary instruments, in particular to a medicine dispensing device for root canals. Background technique [0002] When performing root canal treatment, it is necessary to add medicine to the root canal. Before adding, various medicines need to be mixed according to a certain proportion. The traditional operation is that the medical staff manually squeeze out the medicine and judge by manual comparison ratio. After uniformity, another instrument is used to send the medicine into the root canal. In actual operation, the extruded medicine is in the form of a paste, and the medicine is extruded into a strip shape, and the diameters of each part of the strip medicine are different. It is easy to make errors in judging the volume of the medicine manually, resulting in mixing after proportioning. There is an error in the proportion of the medicine, which is not conducive to root canal treatment. Contents of t...
