Detailed Description

The essential features and advantages of the utility model will be further elucidated with reference to the examples, without however being limited to the embodiments listed.

As shown in fig. 1 to 5, a marrow sampling device for hematology department of the present embodiment includes a bracket 1 and a rotating assembly 2, the bracket 1 includes a supporting plate 3 and an adjusting assembly 4, the supporting plate 3 is disposed on the adjusting assembly 4, and the height of the supporting plate 3 can be adjusted by the adjusting assembly 4. The rotating assembly 2 is arranged on the supporting plate 3, the rotating assembly 2 comprises a rotating member 5 and a supporting seat 6, the supporting seat 6 is arranged on the rotating member 5, the supporting seat 6 is provided with a first channel 61 and an open end 62, the open end 62 is communicated with the first channel 61, and a needle 71 of the extracting device 7 is inserted into the first channel 61 through the open end 62. The bottom of the rotating member 5 is provided with a connecting portion 51, and the connecting portion 51 is in threaded connection with the screw hole 31 of the support plate 3, so that the rotating member 5 can be lifted by rotating the rotating member 5. The connecting portion 51 has a tip portion 52 at one end, and the tip portion 52 is located in the screw hole 31 and communicates with a second passage 53 of the rotary member 5, the second passage 53 being disposed coaxially with the first passage 61. In the above technical solution, when it is necessary to sample bone marrow, the holding tube 10 containing bone marrow is placed under the supporting plate 3, the rotating member 5 is rotated to make it descend, and the plug 8 above the holding tube is pierced by the tip 52; needle 71 is then inserted through open end 62, through tip 52 and into containment tube 10 to withdraw the sample, and the withdrawal means 7 of the illustrated embodiment is a syringe.
