Detailed Description
The utility model is described in detail below with reference to the figures and the embodiments.
Example 1
A bone marrow puncture device for hematology department, as shown in figure 1-figure 5, comprises a bracket 1, a connecting plate 2, fixed blocks 3, first sliders 4, reset springs 5, puncture needles 6, first connecting rods 7, pressing blocks 8, compression springs 9 and pressing rods 10, wherein the bracket 1 is arranged on the left side and the right side of the connecting plate 2, the fixed blocks 3 are symmetrically arranged on the left side and the right side of the middle of the connecting plate 2, the first slider 4 is arranged between the inner sides of the two fixed blocks 3 in a sliding manner, the reset springs 5 are sleeved on the two fixed blocks 3, the two ends of the reset springs 5 are respectively connected on the fixed blocks 3 and the first sliders 4, the puncture needle 6 is arranged in the middle of the first slider 4 in a sliding manner, the first connecting rods 7 are arranged on the left side and the right side of the first slider 4, the pressing blocks 8 are arranged between the inner sides of the two first connecting rods 7 in a sliding manner, the pressing blocks 8 are connected with the puncture needle 6, the compression springs 9 are sleeved on the two first connecting rods 7, two ends of the compression spring 9 are respectively connected to the first sliding block 4 and the pressing block 8, and a pressing rod 10 is arranged on the rear side of the pressing block 8.
When a doctor needs to perform bone marrow puncture on people, the doctor can firstly place the connecting plate 2 above the people, then fix the bracket 1 on a bed of a patient, then enable the pressure rod 10 to move downwards, thereby enabling the pressing block 8 and the puncture needle 6 to move downwards, further enabling the first sliding block 4 and the first connecting rod 7 to move downwards, further enabling the return spring 5 to be compressed, enabling the puncture needle 6 to vertically penetrate into a bone marrow cavity of the people to extract bone marrow fluid, then the doctor can release the pressure rod 10, further enabling the return spring 5 to return to enable the first sliding block 4 and the first connecting rod 7 to return, further enabling the pressing block 8 and the pressure rod 10 to return, enabling the puncture needle 6 to extract the bone marrow fluid, when the doctor needs to sterilize the puncture needle 6, the doctor can move the pressure rod 10 upwards, thereby enabling the puncture needle 6 and the pressing block 8 to move upwards, further enabling the compression spring 9 to be stretched, and then the doctor can remove the puncture needle 6 for sterilization, after the disinfection is finished, the doctor can load the puncture needle 6 again, then the doctor can loosen the compression rod 10, so that the compression spring 9 is reset to reset the puncture needle 6 and the pressing block 8, and after the operation is finished, the doctor can take down the bracket 1 and the connecting plate 2.
