Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical examination, in particular to a liquid adding and diluting device for medical examination. BACKGROUND

[0002] Diluent is a solution obtained by adding water (or other solvents) to a pure solution to reduce its concentration. In daily practical experimental operations, pure solutions are usually not required for experiments, so the method of adding water to dilute is used to obtain a solution with lower concentration, thereby better experimental results.

[0003] However, the current liquid adding and diluting device for medical examination usually drips different diluents into the box for stirring. Different diluents need to be dripped into the box in batches, and the working steps are relatively complicated. The efficiency of liquid adding and diluting is low. If the dripping speed of the diluent is too slow, the liquid adding and diluting time will be long, which can easily cause the diluent in the box to evaporate, thereby affecting the final test results.

[0039] Example 2: Based on Example 1, such as Figures 2-17 As shown, it also includes an inflation mechanism, which is mounted on a fixed connecting rod 51. The inflation mechanism includes a fixed circular tube 61, a fixed circular tube 62, a fixed circular tube 63, a one-way valve 64, a fixed ring 65, a compression ball 66, and a circular rod 67. The top of the fixed connecting rod 51 is bolted to the fixed circular tube 61. Four fixed circular tubes 62 are bolted to the fixed circular tube 61. The fixed circular tube 61 communicates with all four fixed circular tubes 62. The fixed circular tubes 62 are fixedly connected to the fixed connecting rod 53. The upper part of the fixed circular tube 61... A fixed circular tube 63 is bolted to a fixed circular tube 61, which is connected to the fixed circular tube 63. A one-way valve 64 is bolted inside the fixed circular tube 63. A fixed ring 65 is bolted to the top of the fixed circular tube 61. A compression ball 66, made of rubber, is fixedly connected to the fixed ring 65. The fixed circular tube 61 is connected to the compression ball 66. A circular rod 67 is rotatably connected between the four fixed connecting rods 53. A through hole is opened on the circular rod 67. A fixing plate 671 is riveted to the circular rod 67. The fixing plate 671 is fixedly connected to the fixing connecting rod 51.

[0040] Initially, the circular rod 67 blocks three of the fixed connecting rods 53. The through hole on the circular rod 67 is connected to another fixed connecting rod 53. When the diluent flows from the outlet at the bottom of the storage bottle 54 into the inlet 48 on the box 3, the operator presses the squeeze ball 66, causing the air inside the squeeze ball 66 to enter the storage bottle 54 above the inlet 48 through the first fixed circular tube 61, one of the second fixed circular tubes 62, and one of the fixed connecting rods 53, thereby increasing the air volume in the storage bottle 54 above the inlet 48. The pressure causes the diluent in the storage bottle 54 above the inlet 48 to flow down quickly. This speeds up the flow of the diluent into the tank 3, shortening the dilution time and reducing the evaporation of the liquid in the tank 3. This effectively reduces the error in the final test results. When the operator stops pressing the squeeze ball 66, the squeeze ball 66 will rebound under the action of elasticity and draw air into the fixed round tube 62 through the fixed round tube 1 61, thereby drawing in external air into the squeeze ball 66.

[0042] When the rotating link one 43 drives the box 3 to rotate, the box 3 drives the fixed link six 72 to rotate, the rotation of the fixed link six 72 drives both the rotating link two 71 and the gear two 73 to rotate around the gear one 45, the gear two 73 rotates around the gear one 45 while also rotating, the rotation of the gear two 73 drives both the rotating link two 71 and the fixed link six 72 to rotate, and the two rotating link two 71 stirs the diluent in the box 3, so that the diluent in the box 3 can be stirred more evenly, so that different kinds of diluent can be mixed more fully, and then the subsequent diluent can be tested more accurately.

[0043] Example 4: on the basis of example 3, as shown in Figure 13 and Figure 14 As shown, the device also comprises a funnel 81, and the liquid inlet on the top of each of the liquid storage bottles 54 is connected with the funnel 81 through bolt connection, and the funnel 81 is communicated with the liquid storage bottle 54.

[0044] The funnel 81 can make the staff pour the diluent more accurately, avoid waste of the diluent, so that the addition amount of various diluents is more accurate, and further facilitate the subsequent more accurate testing of the diluent.

[0045] Example 5: on the basis of example 4, as shown in Figures 1-12 The device also comprises a fork rod 91, and two fork rods 91 are symmetrically arranged between the two fixed link six 72 through rivet connection.

[0046] The device also comprises an anti-skid pad 101, and the anti-skid pad 101 is fixedly connected to the lower part of the support base 1.

[0047] The fork rod 91 can increase the contact area of the fixed link six 72 and the diluent, so that different kinds of diluent can be mixed more fully.

[0048] The anti-skid pad 101 can increase the friction between the support base 1 and the ground, and enhance the stability of the device.
