Flow velocity controllable bloodletting device

Abstract

The invention discloses a flow velocity controllable bloodletting device, which belongs to the field of medical instruments and is characterized by comprising a bloodletting tube, a bloodletting bottle, an air pump, an air suction tube and a clamp, a float valve is arranged in the bloodletting bottle and comprises a shell and a floater; the clamp comprises two arms and a corrugated pipe, the two arms are connected with each other to form an included angle, and the other ends of the two arms are connected to the two ends of the corrugated pipe respectively; one end of the corrugated pipe is closed, and the other end is communicated with the exhaust pipe; the blood release tube penetrates through the clamp, and the blood release tube can be clamped tightly after the clamp is closed. Compared with the prior art, the automatic bloodletting device has the characteristic of automatically controlling bloodletting speed.

Description

technical field [0001] The present invention relates to a medical device, in particular to a flow rate controllable bloodletter suitable for bloodletting therapy. Background technique [0002] Polycythemia vera (PV) is a clonal chronic myeloproliferative disorder of hematopoietic stem cells. The onset of PV is insidious and the progress is slow. The main pathophysiological basis of clinical manifestations is the increase of total blood (red blood cell) volume and the increase of blood viscosity, which leads to slow blood flow and tissue ischemia in various organs of the body. Headache, dizziness, fatigue, tinnitus, vertigo, forgetfulness and other similar neurosis symptoms may appear in the early stage, and later numbness and tingling of the extremities, sweating, visual disturbance, itchy skin and peptic ulcer. Among the complications, bleeding, thrombosis and embolism are the most common, and are often the main causes of death. If the disease is treated with drugs, the o...

Problems solved by technology

During bloodletting, it is necessary to control the amount of blood flowing out. The usual method is to set a scale in the bloodletting container. When the blood reaches the set scale value, the bloodletting will stop. Therefore, during the bloodletting process, medical staff need to keep an eye on the amount of the bloodletting container to avoid excessive bloodletting. Therefore, this method is more labor-intensive

In addition, it is necessary to control the speed of bloodletting during bloodletting. Too fast bloodletting may cause dizziness and other symptoms, and too slow bloodletting will cause the bloodletting process to be too long, and the patient will take too long
