Blood-drawing auxiliary device for internal medicine of hematology

Abstract

The invention discloses a blood-drawing auxiliary device for the internal medicine of hematology. The blood-drawing auxiliary device comprises a base plate, wherein a control switch is arranged on the front side surface of the base plate, a fixed base is fixed to the left side of the upper surface of the base plate, a hinge base is fixed to the upper surface of the base plate on the right side of the fixed base, and a hinge plate is hinged to the upper end part of the hinge base. The blood-drawing auxiliary device for the internal medicine of hematology is reasonable in structural design, and easy and convenient to use, the forearm of a patient is placed on a fixing cushion and then the hand of the patient holds a handle, so that the unconscious shaking during the blood drawing process can be prevented, the work difficulty in blood-drawing examination of a doctor is reduced, and the discomfort of the patient is alleviated; a drawer can be used for placing medicinal cotton and is close to the medical staff, thus taking is convenient, the vein belt can be automatically bound and pressed, the hinge plate rotates under the driving of an electric telescopic rod, so that a vein-pressing belt is tightened to bind the arm of the patient, therefore, convenience is provided for blood drawing, the work efficiency in blood-drawing examination of the doctor is greatly improved, and the workload of the medical staff is alleviated.

Description

technical field [0001] The invention relates to the technical field of hematology auxiliary devices, in particular to a blood drawing auxiliary device for hematology. Background technique [0002] At present, when a doctor draws a blood sample for a patient, he usually puts a liner on the table under the patient's arm, and then uses a rubber tube to tie the patient's arm tightly to expose the blood vessel, and then directly uses a blood-drawing needle. To draw blood, use a rubber tube to tie the patient's arm tightly, which is time-consuming and labor-intensive, and if the binding time is too long, it will easily cause subcutaneous congestion and increase the pain of the patient. Especially for organizational blood testing, due to the large number of people, Repeated tying of the cuff can cause great burden, and the patient's arm is easy to move at the same time. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome ...
