[0002] In the laboratory, routine blood tests are the most common tests. To maintain health and prevent certain diseases, regular blood tests are necessary. However, existing routine blood tests often require multiple manual steps to test samples in the sampling tube. First, medical staff must shake the sampling bottle several times to ensure the uniformity and fluidity of the sample. Then, they hold the sampling bottle under the sampling needle and insert the sampling needle into the bottle until it contacts the sample. The test is considered complete only when the sampling needle absorbs part of the sample. The entire process is complex and inconvenient, resulting in low test efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide an auxiliary device for a routine blood tester, aiming to solve the problems of multiple links involved in routine blood testing, inconvenient operation and low detection efficiency.

[0008] a brake sleeve, disposed between the connecting pipe and the output shaft to ensure the stability of the position between the connecting pipe and the output shaft;

[0009] The supporting plate is positioned on the inner wall of the top end of the connecting tube. The supporting plate and the inner wall of the connecting tube are formed into a supporting groove for placing the sampling tube.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also refer to Figures 1 to 3 , an auxiliary device provided by the present invention and applied to a routine blood tester is now described. An auxiliary device applied to a routine blood tester, comprising: a retaining frame 1, a motor 2, a connecting tube 5, a brake sleeve 4 and a support plate 7. The retaining frame 1 is used to be positioned below the sampling needle 8 of the detector. The motor 2 is installed in the retaining frame 1. The connecting tube 5 is slidably sleeved on the outside of the output shaft 3 of the motor 2, and the brake sleeve 4 is arranged between the connecting tube 5 and the output shaft 3 to ensure the stability of the position between the connecting tube 5 and the output shaft 3. The support plate 7 is positioned on the inner wall of the top end of the connecting tube 5, and the support plate 7 and the inner wall of the connecting tube 5 are surrounded by a support groove for placing the sampling tube 6; the connecting tube 5 is used to drive the sampling tube 6 to rotate with the help of the output shaft 3.

[0028] The auxiliary device for a routine blood tester provided by the present invention has the following advantages: Compared with the prior art, in the auxiliary device for a routine blood tester provided by the present invention, a retaining frame 1 is positioned below a sampling needle 8, and a motor 2 is mounted within the retaining frame 1. A connecting tube 5 is slidably mounted on the outside of an output shaft 3 of the motor 2, while a brake sleeve 4 is disposed between the connecting tube 5 and the output shaft 3. A support plate 7 is positioned on the top inner wall of the connecting tube 5.

[0029] In actual use, the sampling tube 6 is first placed in the supporting groove, and then the connecting tube 5 is driven upward to allow the sampling needle 8 of the detector to be inserted into the sampling tube 6. The rotation of the motor 2 causes the output shaft 3 and the connecting tube 5 to rotate, and finally the sampling tube 6 is driven to rotate, thereby disturbing the blood in the sampling tube 6. The present application has a simple structure, is easy to operate, and has a low cost, which can reduce the process and labor intensity of routine blood testing.

[0030] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 2 and Figure 3, the brake sleeve 4 is bonded to the output shaft 3. First of all, the sampling tube 6 itself has a certain weight. The gravity of the connecting tube 5 and the sampling tube 6 needs to act on the brake sleeve 4. The friction between the brake sleeve 4 and the output shaft 3 ensures the stability of its own position. For this reason, the brake sleeve 4 is first made of flexible material and has a large friction coefficient on the surface. After the detection is completed, the connecting tube 5 needs to be pressed down to replace the sampling tube 6. Therefore, it is necessary to ensure that there is sufficient contact area between the brake sleeve 4 and the output shaft 3. The brake sleeve 4 needs to be bonded to the output shaft 3. The above settings can ensure that the brake sleeve 4 is firmly connected to the output shaft 3.

[0031] In some embodiments of an auxiliary device for a routine blood tester provided in the present application, the motor 2 is electrically connected to a battery and a resistance regulator, and the resistance regulator is used to adjust the operating voltage of the motor 2. Different samples can withstand different stirring speeds, which requires that the motor 2 can have different rotational speeds. Based on the above reasons, it is necessary to change the operating voltage of the motor 2. The rotation of the motor 2 requires energy supply. For this purpose, a battery and a resistance regulator are provided on one side of the holder 1. The resistance regulator can adjust its own resistance. At this time, the battery, the resistance regulator and the motor 2 form a pathway. By adjusting the resistance value of the motor 2 through the resistance regulator, the voltage across the motor 2 can be changed. After the voltage changes, the speed of the motor 2 also changes accordingly.

[0032] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 2 , an anti-slip coating is provided in the supporting groove. When the motor 2 rotates, the output shaft 3 is required to drive the connecting tube 5 and the sampling tube 6 in the supporting groove to rotate. Since the sampling tube 6 is inserted into the supporting groove later, it is necessary to ensure that the outer wall of the sampling tube 6 has sufficient contact area and mutual force with the supporting groove. The ultimate goal is to ensure that there is sufficient friction between the sampling tube 6 and the connecting tube 5, because only sufficient friction can prevent the connecting tube 5 from moving relative to the sampling tube 6. Normally, the anti-slip coating has a certain degree of elasticity, because only in this way can the sampling tube 6 be inserted into the supporting groove, ensuring that the sampling tube 6 has a certain squeezing force on the anti-slip coating.

[0033] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 2 and Figure 3The output shaft 3 is prismatic, and the bottom of the connecting tube 5 is provided with a prismatic groove that matches the output shaft 3. The connecting tube 5 needs to slide relative to the output shaft 3. More importantly, the output shaft 3 needs to drive the connecting tube 5 to rotate. For the reasons mentioned above, if the output shaft 3 is cylindrical, the sampling tube 6 can only be driven by the friction between the brake sleeve 4 and the output shaft 3, and the friction between the connecting tube 5. The friction transmission method is unreliable and has the risk of slipping.

[0034] In order to avoid the above problems, firstly, the output shaft 3 is prismatic and the bottom end of the connecting tube 5 is also a matching prismatic groove. The cooperation between the prismatic shaft and the groove can ensure reliable transmission.

[0035] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 1 and Figure 2 , an adhesive pad is provided at the bottom of the holder 1. During the actual operation, the inspector needs to operate the connecting tube 5 to move upward. At this time, if there is no restraint between the holder 1 and the desktop, the position of the holder 1 cannot be guaranteed, and the final result is that the sampling tube 6 and the sampling needle 8 are not aligned. In order to avoid the above problems, an adhesive pad is provided at the bottom of the holder 1, which can position the entire holder 1 and adsorb it on the desktop. In some occasions, glue can also be applied to the bottom of the holder 1 to ensure the stability of the position of the holder 1 relative to the desktop.

[0036] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 2 The connecting tube 5 is made of a transparent material. To effectively observe the state of the sample in the sampling tube 6 and the position of the sampling needle 8 relative to the sampling tube 6, the connecting tube 5 is made of a transparent material, usually plastic or glass, and is provided with a scale, which can be used to measure the volume of the sample in the sampling tube 6 to a certain extent.

[0037] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 1 and Figure 2 The ball head of the motor 2 is connected to the holder 1. It should be noted that part of the sampling needle 8 is not set vertically downward, but tilted downward. Based on the above reasons, it is necessary to adjust the angle of the connecting tube 5. The ultimate goal is to adjust the angle of the sampling tube 6. To this end, the ball head of the motor 2 can be connected to the holder 1. The ball head connection can adjust the spatial angle of the motor 2 relative to the holder 1. The ultimate goal is to adjust the angle of the sampling tube 6. The most ideal effect is to keep the axis of the sampling tube 6 as parallel as possible to the sampling needle 8 to avoid collision between the sampling tube 6 and the sampling needle 8.

[0038] In some embodiments of the auxiliary device for a blood routine tester provided in this application, please refer to Figure 2 The brake sleeve 4 is mounted on the output shaft 3, and the connecting tube 5 is mounted on the outside of the brake sleeve 4. First, the connecting tube 5 needs to slide relative to the output shaft 3. It is precisely because of this requirement that the height of the sampling tube 6 can be changed so that the sampling needle 8 of the detector can be inserted into the sampling tube 6. More importantly, the sampling tube 6 needs to be rotated by the motor 2. Only when the sampling tube 6 rotates can the blood inside it be disturbed.

[0039] To achieve the above technical effects, it is necessary to maintain the position of the connecting tube 5 stable after it moves upward for a certain distance. To this end, a brake sleeve 4 is mounted on the output shaft 3, and the connecting tube 5 is mounted on the brake sleeve 4. The brake sleeve 4 can be made of rubber material. It is precisely because of the large friction coefficient of the surface of the brake sleeve 4 that sufficient maximum static friction can be ensured between the connecting tube 5 and the brake sleeve 4.

[0040] In some embodiments of the auxiliary device for a routine blood tester provided in this application, a heating coil is provided in the support groove. The provision of the heating coil can increase the fluidity of the sample in the sampling tube 6, making the test result more accurate.

[0041] In some embodiments of an auxiliary device for a routine blood tester provided herein, a support plate 7 is detachably connected to a connecting tube 5. A power supply is provided within the connecting tube 5 and electrically connected to the heating coil. By replacing the support plate 7, different shapes of sampling tubes 6 can be accommodated. In this case, the support plate 7 can be replaced with a different shape. The support plate 7 can be directly plugged into the connecting tube 5, and the power supply can be an electronic device or a conventional battery.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
