Abstract

The invention discloses a detection device for determining a bone marrow microcirculation environment of a patient after hematopoietic stem cell transplantation. The detection device includes a shell;the right side of the shell is fixedly connected with a positioning seat; the front surface of the positioning seat is fixedly connected with a fixed handle; the front surface of the fixed handle ismovably connected with a movable handle; a reset spring is movably connected between the fixed handle and the movable handle; the left end of the movable handle is movably connected with a push block;the left side of the shell is fixedly connected with a limiting seat; the front surface of the limiting seat is movably connected with an ejector block; a limiting elastic piece is movably connectedto the lower portion of the ejector block. According to the detection device for determining the bone marrow microcirculation environment of the patient after hematopoietic stem cell transplantation,through the cooperative use of a stroke ruler and a stroke scale, the movement stroke of the puncture needle push rod can be indicated, so that the accuracy of the puncture depth of a puncture needleis ensured, the safety and the accuracy during operation are improved, the safety of a patient is ensured, and meanwhile, the surgical risk is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a detection device for measuring the bone marrow microcirculation environment of patients after hematopoietic stem cell transplantation. Background technique [0002] Hematopoietic stem cell transplantation is a process in which patients first receive ultra-high doses of radiotherapy or chemotherapy (usually lethal doses of radiotherapy and chemotherapy), sometimes in combination with other immunosuppressive drugs to remove tumor cells and abnormal clone cells in the body, and then reinfuse them from themselves or others Hematopoietic stem cells, a therapeutic means to rebuild normal hematopoietic and immune function. [0003] In order to evaluate the patient's physical condition and rehabilitation after transplantation, and also to monitor the effect of transplantation, it is necessary to detect the microcirculation environment of the patient's bone marrow after bone m...
