A puncture point intravenous branch injection device

Abstract

The invention relates to the technical field of injection devices, in particular to a venous branch injection device at a puncture point, comprising a main body of the injection device, a support platform is welded to the middle of the lower surface of the inner wall of the main body of the injection device, and the main body of the injection device is A clamping mechanism is provided inside, and the clamping mechanism includes a first slider, a first connecting rod, a second slider, a support rod, a splint, a second connecting rod, a third connecting rod, a sliding rod, a screw rod and a knob . The present invention avoids that the existing push injection device is generally a single syringe, and its structure is simple. When injecting liquid to the affected arm, some liquid may be relatively thick, resulting in the need for a long time for injection, which may cause the patient to The arm of the device may move, especially when the patient is a child, which may cause the needle tube of the bolus injection device to fall off from the blood vessel, and even cause injury to the patient, which greatly improves the practicability of the device.

Description

technical field [0001] The invention relates to the technical field of bolus injection devices, in particular to a puncture point venous branch bolus injection device. Background technique [0002] Vein refers to the vascular body that starts from capillaries and transports blood from various organs and tissues of the body back to the heart. The wall of the vein is thin, the lumen is large, the elasticity is small, the internal pressure is low, the blood flow is slow, and the blood in the vein contains relatively Too much carbon dioxide, blood color is dark red, and the vein is a branch. The push injection device is a push injection device for superficial veins. Superficial veins are also called subcutaneous veins. , mainly collect blood from the skin and superficial mucous membranes, pour it into the deep veins, and reinfuse the blood. Because the superficial location is prone to damage and cause bleeding, and because the superficial surface is fully exposed, blood collecti...

Problems solved by technology

[0004] The purpose of the present invention is to provide a puncture point vein branch injection device to solve the problem that the existing injection device proposed in the above background technology is generally a single syringe, and the arm of the patient and the hand of the doctor may shake for a long time. , leading to the problem of needles causing damage to the patient's blood vessels
