Bone marrow puncture extraction device for hematology department

Abstract

The invention discloses a bone marrow puncture extraction device for hematology department. The bone marrow puncture extraction device comprises an outer shell, wherein a grip is arranged at the bottom of the outer shell, a sealing structure is disposed at the top of the outer shell and a fixing structure matched with the sealing structure is disposed on the left side of the top of the outer shell. The sealing effect is achieved through cooperative use of the sealing structure and the fixing structure, the blood collection tube is embedded into the inner cavity of the fixing frame and communicates with the connecting structure, the surface of the sealing shell is sleeved with the connecting sleeve arranged at one end of the air tube, and at the moment, the surface of the connecting structure is sleeved with a needle head. Moreover, one side of the needle head is tightly attached to the limiting ring, at the moment, the grip is held and the needle head is pierced into the body of the patient, the index finger pulls a trigger to trigger the micro-gap switch finally, a draught fan starts to work, and air in the inner cavity of the blood collection tube is pumped out to form a negativepressure, and then blood in the body of the patient is pumped into the inner cavity of the blood collection tube, and the bone marrow puncture extraction step can be completed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone marrow puncture extraction device for hematology. Background technique [0002] Medical devices refer to instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are directly or indirectly used on the human body, including the required computer software.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a bone marrow puncture extraction device for hematology department, which has the advantages of easy force, convenient operation, and high extraction efficiency, and solves the problem that when the bone marrow puncture is extracted for hematology department, the syringe is mostly used for blood collection inspection directly. The structure is single. In the actual use process, the extraction efficiency of bone marrow puncture is low. When drawing blood, manpower is required to extract it. The speed of extraction is difficult to be uniform, which causes great pain to patients, and the design of the syringe is not conducive to medical staff. It takes a long time for medical staff to study and train to complete the bone marrow puncture, which is not conducive to the use of users
