Breastbone puncture needle fixing device

Abstract

The invention discloses a breastbone puncture needle fixing device. The fixing device comprises a base, a fixing part, a guidance part, a support part and a pressure detection part. Through the fixingpart, the base, the guidance part and the support part are installed on the surface of a patient, so it is convenient for an operator to insert needles and carry out guidance by use of the breastbonepuncture needle fixing device effectively. Meanwhile, by use a pressure detection part, whether an operator successfully pierces the needle into a bone marrow cavity can be timely fed back, and a displacement display is arranged on one end face of the fixing part, so when the puncture fails, puncture needles are prevented from piercing too deep or even piercing the breastbones. When the puncturesuccess rate is effectively improved, an accident that the atriums or main arteries are damaged caused by the fact that the breastbone is pierced can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical and health equipment, and in particular relates to a sternum puncture needle fixer. Background technique [0002] Sternacentesis is a diagnostic method for diseases such as blood diseases and parasitic diseases. When utilizing the sternal puncture needle to puncture, because the sternum is flat, the sternal puncture needle is easy to slide after sternal puncture and cannot be fixed well, and it is very easy to penetrate the sternum, causing pneumothorax, which brings inconvenience to the treatment of patients. [0003] Chinese invention patent specification CN 203677133U discloses a sternal puncture needle holder capable of effectively fixing a puncture needle. The sternal puncture needle fixer includes a fixing plate, a through hole is set on the fixing plate, a needle guide plate is arranged at the edge of the through hole of the fixing plate, a bone needle groove is arranged on the upper surfa...

AI Technical Summary

Problems solved by technology

[0004] Adopting this sternal puncture needle fixer solves the problem of fixing and guiding the bone puncture needle on the fixing plate, but the relative sliding between the patient’s skin surface and the fixing plate may exist due to the use of the fixing belt to fix the fixing plate, which cannot be done well. In addition, when performing sternal puncture, judging that the bone puncture needle penetrates the front bone of the sternum still needs to rely on the operator's feel of the sternum puncture, and the depth of bone puncture needle puncture depends on the operator. Subjective estimation, it is very easy to penetrate the sternum and puncture the patient's atrium and great blood vessels, which not only brings inconvenience to the patient's treatment, but may also cause life-threatening
