[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 3 An automated quantitative sampling device for bone marrow aspiration includes: a puncture needle 1, a sampling tube 2, and a housing 3;

[0022] A flow sensor 4 is installed on the outer wall of the sampling tube 2. The sampling tube 2 is connected to the puncture needle 1. The detection probe of the flow sensor 4 extends into the interior of the sampling tube 2. A sample collection container 5 is installed at the top of the sampling tube 2. A cylinder 6 is installed at the top of the sample collection container 5. A piston 7 is installed inside the cylinder 6. A connecting rod 8 is installed at the top of the piston 7.

[0023] A controller 9 is installed on the outer wall of the housing 3, and a voice broadcaster 10 is installed on one side of the outer wall of the housing 3. The controller 9 is electrically connected to the flow sensor 4 and the voice broadcaster 10 respectively.

[0024] The technical solution provided by this utility model is as follows: During operation, the operator adjusts the parameters of the flow sensor 4 by operating the controller 9. When adjusting the parameters, the parameters can be adjusted according to the amount of bone marrow sample extracted. After adjustment, the operator performs a puncture on the patient, inserting the puncture needle 1 into the patient's bone. Then, the connecting rod 8 is pulled outwards from the cylinder 6, causing the piston 7 to move inside the cylinder 6. Under the action of the piston 7, the bone marrow is extracted and enters the sample collection container 5 through the puncture needle 1 and the sampling tube 2. At the same time, the detection probe of the flow sensor 4 detects the amount of bone marrow extracted. When the set parameters are reached, the information is transmitted to the controller 9. The controller 9 controls the voice broadcaster 10 to start, so that the voice broadcaster 10 issues a voice to inform the operator that the required sample has been obtained. Then, the puncture needle 1 is pulled out, and the connecting rod 8 is pushed to push the bone marrow sample onto the glass slide for detection and analysis. This achieves the purpose of quantitative bone marrow sampling and effectively prevents errors caused by human factors, such as over-sampling or under-sampling.

[0025] Furthermore, the outer side wall of the outer casing 3 is provided with a plurality of protrusions 11, which are arranged in a circular array.

[0026] Specifically, multiple protrusions 11 on the outer casing 3 are used to prevent the operator from slipping when holding the outer casing 3.

[0027] Furthermore, the tip of the puncture needle 1 is conical, and the puncture needle 1 is made of titanium alloy.

[0028] Specifically, the conical tip of the puncture needle 1 is very small and sharp, enabling efficient puncture with minimal force. The puncture needle 1 is made of titanium alloy, which has excellent biocompatibility and prevents immune or allergic reactions in human tissues.

[0029] Furthermore, the outer wall of the outer casing 3 is coated with a wear-resistant coating 12, which is specifically a polyurethane coating.

[0030] Specifically, the polyurethane coating has good wear resistance and elasticity, which can resist impact and wear, and extend the service life of the outer shell 3.

[0031] Furthermore, the outer wall of the wear-resistant coating 12 away from the outer shell 3 is coated with an antibacterial coating 13, specifically a silver ion antibacterial coating.

[0032] Specifically, the silver ions in the silver ion antibacterial coating can destroy bacterial cell membranes, inhibit their metabolism and reproduction, and prevent the growth of bacteria, fungi and viruses.

[0033] Furthermore, a pull block 14 is fixedly connected to the top of the connecting rod 8, and a groove 15 is provided on the outer side wall of the pull block 14.

[0034] Specifically, the pull block 14 facilitates the pulling of the connecting rod 8, and the groove 15 on the pull block 14 facilitates operation.

[0035] The working principle of this utility model is as follows: During operation, the operator adjusts the parameters of the flow sensor 4 by operating the controller 9. The parameters can be adjusted according to the amount of bone marrow sample extracted. After adjustment, the operator performs a puncture on the patient, inserting the puncture needle 1 into the patient's bone. Then, the connecting rod 8 is pulled outwards from the cylinder 6, causing the piston 7 to move inside the cylinder 6. Under the action of the piston 7, the bone marrow is extracted and passes through the puncture needle 1 and sampling tube 2 into the sample collection container 5. Simultaneously, the detection probe of the flow sensor 4 detects the amount of bone marrow extracted. When the set parameters are reached, the information is transmitted to the controller 9. The controller 9 then activates the voice broadcaster 10, which announces to the operator that the required sample has been obtained. The puncture needle 1 is then withdrawn, and the connecting rod 8 is pushed to push the bone marrow sample onto a glass slide for analysis. This achieves the purpose of quantitative bone marrow sampling, effectively preventing errors caused by human factors, such as over- or under-sampling.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
