Cerebrospinal fluid extraction positioning device for hematologic tumor patient

Abstract

A cerebrospinal fluid extraction positioning device for a hematological tumor patient comprises a bed board, a supporting box is fixedly connected to the right side of the surface of the upper end of the bed board, a first mounting box capable of moving up and down or moving front and back is mounted at the upper end of the supporting box, and a second mounting box capable of moving left and right is mounted at the front end of the first mounting box; a special-shaped supporting plate capable of being overturned front and back is installed at the lower end of the second mounting box, an annular plate capable of moving up and down is installed on the inner wall of the special-shaped supporting plate, a rotatable annular handle is installed at the upper end of the annular plate, and a plurality of first clamping plates which are evenly distributed are installed at the upper end of the annular handle. A plurality of second clamping plates which are uniformly distributed are mounted at the lower end of the annular plate; when the annular handle rotates, a structure that the first clamping plates and the second clamping plates are folded inwards or spread outwards at the same time can be formed. Through multi-degree-of-freedom rapid positioning, adjustment and control, precise puncture positioning can be achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cerebrospinal fluid extraction and positioning device for patients with blood tumors. Background technique [0002] The common types of hematological tumors mainly include various types of leukemia, multiple myeloma and malignant lymphoma. Patients with hematological tumors often need to aspirate cerebrospinal fluid to detect whether there are lesions in the brain; cerebrospinal fluid is: cerebrospinal fluid exists in the ventricles and arachnoid A colorless and transparent liquid in the lower cavity. The commonly used suction method is lumbar puncture. The needle is about 4-6cm (approximately 3-4cm for children). Since the lumbar spine is relatively hard, it is difficult to control the force of manual pressing on the puncture needle. During puncture, medical staff need to hold it in hand to assist fixation. The existing cerebrospinal fluid of patients with blood tumors The ex...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a cerebrospinal fluid extraction and positioning device for patients with blood tumors, which can accurately locate the patient's lumbar puncture site according to specific needs, and can also replace the medical staff's hand-held auxiliary fixed puncture needle, and the puncture depth, The strength is easy to control and easy to control, which effectively solves the problems that the manual pressure of the puncture needle is not easy to control, and the medical staff needs to hold the auxiliary fixation when puncturing.
