Problems solved by technology

The medical worker fixes the skin at the puncture point with his left hand, and holds a No. 20 puncture needle (No. 21-22 for children) in his right hand. The puncture needle is inserted vertically along the back and slowly along the spinous process. This method is difficult to implement because the patient’s back is very difficult. Keep completely perpendicular to the bed surface, which causes the direction of needle insertion to not be perpendicular to the back, which in turn causes the needle tip to encounter bone during needle insertion, resulting in puncture failure
Inexperienced doctors have a low success rate of puncture and take a long time for puncture, which brings great pain to patients

Embodiment Construction

[0013] Such as figure 1 As shown, a lumbar puncture guiding device includes a pressing plate 1, intervertebral space feet 2 and puncture holes 3, the pressing plate 1 is a rectangular flat plate, a groove 4 is arranged around the pressing plate 1, and anti-slip particles 5 are arranged on the groove 4 A puncture hole 3 is set at the center of the pressing plate 1, and intervertebral space feet 2 are set under the pressing plate 1.

[0014] Wherein, the thickness of the pressing plate 1 is 15 mm.

[0015] Wherein, the puncture hole 3 is a small circular hole with a diameter of 2-2.5 mm.

[0016] Wherein, intervertebral space feet 2 are symmetrically arranged around the puncture hole 3 .

[0017] Wherein, the intervertebral space feet 2 are cylindrical, and the width between two intervertebral space feet 2 is equal to the width of the intervertebral space of 20 mm.

[0018] Among them, the present invention is a transparent PP material.

[0019] The specific embodiment of th...

Abstract

The invention discloses a lumbar puncture guiding device. The lumbar puncture guiding device comprises a pressing plate, lumbar space feet and a puncturing hole, wherein the pressing plate is a rectangular slab; grooves are formed in the periphery of the pressing plate; skidproof granules are arranged on each groove; the puncturing hole is formed in the central position of the pressing plate; andthe lumbar space feet are arranged below the pressing plate. According to the lumbar puncture guiding device disclosed by the invention, the puncturing position can be accurately positioned, the success rate of puncturing is increased, the pain of a patient is reduced, the manufacturing cost is low, the operation is simple and convenient, and the lumbar puncture guiding device is practical.

Description

technical field [0001] The invention relates to the field of clinical medical auxiliary equipment, in particular to a lumbar puncture guiding device. Background technique [0002] Clinically, lumbar puncture usually requires the patient to lie on his side on a hard plank bed, with his back perpendicular to the bed surface, his head bent forward to his chest, and his hands embracing his knees close to his abdomen to make his trunk arched. The intersection of the posterior superior iliac spine and the posterior midline is used as the puncture point, usually in the space between the spinous processes of the 3rd and 4th lumbar vertebrae, and sometimes in the space of the previous or next lumbar vertebrae. The medical worker fixes the skin at the puncture point with his left hand, and holds a No. 20 puncture needle (No. 21-22 for children) in his right hand. The puncture needle is inserted vertically along the back and slowly along the spinous process. This method is difficult to...
