Problems solved by technology

The tourniquet is usually a rubber tube, which is manually operated, and the tightness of the binding is required. It cannot be too tight because it cannot affect the blood backflow, and it cannot be too loose because it cannot achieve the pressurization effect; for Patients with anemia, thin blood vessels and insufficient local blood perfusion have poor blood collection results; and because the diameter of the rubber tube is small, if the winding and knotting method is not handled properly, it is easy to cause damage to the local skin

Embodiment 1

[0025] Embodiment 1, a kind of upper arm pressure band that is convenient for blood drawing, it comprises cuff 1, and cuff 1 is provided with air bag 2, and air bag 2 is provided with inflation port and is connected with inflation device 5 through trachea, and cuff 1 is provided with lock The fastener makes the cuff 1 ring-shaped and sleeved on the arm; there are multiple airbags 2 arranged in the width direction of the cuff 1 , and each airbag 2 is directly or indirectly connected to the inflatable device 5 .

[0026] Each airbag 2 is provided with an inflation port and is connected to the inflation device 5 through the pipeline I3, and the pipeline I3 is provided with a valve, which is convenient for controllable and optional inflation;

[0027] Further, it also includes a controller 4 , the valve is a solenoid valve 7 , and the pipeline I3 is provided with a pressure sensor 6 and the solenoid valve 7 connected to the controller 4 .

[0028] Described controller 4 comprises ...

Embodiment 2

[0037] Embodiment 2 An upper arm pressurized belt that is convenient for blood drawing, it includes a cuff 1, an airbag 2 is arranged inside the cuff 1, the airbag 2 is provided with an inflation port and is connected with an inflation device through a trachea, and the cuff 1 is provided with a locking member The cuff 1 is placed on the arm in a ring; the airbags 2 are multiple, arranged in the width direction of the cuff 1, and each airbag 2 is directly or indirectly connected to the inflatable device 5 .

[0038] A plurality of airbags 2 are connected in sequence, and the airbag 2 on the outermost side is connected to the inflator 5 through the pipeline II15, and the airbags 2 are connected through the pressure limiting valve 8. When the first airbag 2 connected to the inflator 5 is full to reach the pressure limit When the valve 8 limits the pressure, the gas enters the second air bag 2 from the first air bag 2 and continues to inflate until the last air bag 2 is full.

Abstract

The invention discloses an upper arm pressurizing belt facilitating blood drawing and a pressurizing method of the upper arm pressurizing belt. The upper arm pressurizing belt comprises a sleeve belt;air bags are arranged in the sleeve belt, provided with an inflation inlet and connected with an inflation device through an air pipe; and the sleeve belt is provided with a lock catch piece so thatthe sleeve belt can be annularly arranged on an arm in a sleeving mode. The number of the air bags is multiple, the air bags are arranged in the width direction of the sleeve belt, each air bag is directly or indirectly connected with the inflation device, pressure is sequentially generated in the width direction of the sleeve belt in the mode that the air bags are inflated in sequence, and therefore blood pressure in blood vessels at the tail ends of limbs in the sleeve belt limiting direction is gradually increased, and blood drawing is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an upper arm pressure belt for blood drawing and sampling. Background technique [0002] At present, in the process of disease diagnosis and treatment, venous blood collection is a commonly used method. The usual method is to place a slipknot on the upper arm, about 6cm above the blood collection site, through the cuff around the arm, and ask the patient to clench and relax the fist several times. times to bulge the veins. The tourniquet is usually a rubber tube, which is manually operated, and the tightness of the binding is required. It cannot be too tight because it cannot affect the blood backflow, and it cannot be too loose because it cannot achieve the pressurization effect; for Patients with anemia, thin blood vessels and insufficient local blood perfusion have poor blood collection results; and because the diameter of the rubber tube is small, if the winding and ...
