Bone marrow blood puncture point positioning, extracting and anti-coagulation device

Abstract

The invention discloses a bone marrow blood puncture point positioning, drawing and anti-coagulation device. The device comprises a positioning device, a blood drawing device and an automatic swinging device, the positioning device comprises a placing plate, a transverse plate with scales is arranged on the placing plate in a sliding mode, a vertical plate with scales is arranged on the transverse plate in a sliding mode, the scales on the transverse plate are distributed in the sliding direction of the vertical plate, the distribution directions of the scales on the transverse plate and the vertical plate are perpendicular, a posterior superior iliac spine positioning plate is slidably arranged on the vertical plate in the scale direction, and a plurality of positioning holes are distributed in the posterior superior iliac spine positioning plate; and the blood drawing device comprises a puncture needle, an inner core is inserted into a through cavity in the puncture needle during puncture, and the inner core is connected with a blood drawing tube during blood drawing. Compared with the prior art, the device has the beneficial effects that: a plurality of puncture points can be quickly found, blood can be directly drawn after puncture is finished, the pain of a patient is reduced, the negative pressure tube can automatically draw blood, bone marrow blood in the negative pressure tube continuously shakes, and blood coagulation is prevented.

Description

technical field [0001] The invention belongs to the field of orthopedic medical devices, in particular to a bone marrow blood puncture point positioning, extraction and coagulation prevention device. Background technique [0002] Stem cell transplantation is one of the most effective methods for the treatment of hematological malignancies at this stage, and it has good curative effect in bone tissue repair and reconstruction. The development of bone tissue engineering technology is based on the use of bone marrow mesenchymal stem cells. Hematopoietic stem cells are mainly derived from bone marrow blood, peripheral blood, and umbilical cord blood, and bone marrow mesenchymal stem cells are mainly derived from bone marrow. For patients who need bone marrow transplantation, hematopoietic stem cell transplantation combined with bone marrow and blood stem cell transplantation can reduce the occurrence of chronic graft-versus-host disease and improve the quality of life of patient...
