A pedicled flap blood flow blocking trainer

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a pedicel flap blood occlusion trainer. The pedicel flap blood occlusion trainer comprises an occlusion box, an occlusion rope, a temperature detector, a control box, an alarm device and a power source. The occlusion box comprises a pressure detecting module and a power mechanism, which are connected with the occlusion rope. The control box comprises a control chip, a pressure control module, a time control module and a temperature control module. Pedicel flap blood occlusion pressure is accurate and controllable, a certain occlusion blood pressure can be achieved, and damage to tissue due to overhigh pressure can be prevented. Occlusion time is accurate and controllable, pressure can be automatically released when the preset time is up, and irreversible damage when medical staff forget time is prevented. When flap is too low in temperature, pressure can be automatically released so as to prevent unnecessary damage of the flap.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a blood flow blocking trainer for a pedicled flap. Background technique [0002] In the operation of pedicled flap transfer to repair wounds, in order to promote the establishment of blood circulation between the flap and the wound in the recipient area, blood flow occlusion training at the flap pedicle is generally started 2 weeks after the operation to prepare for flap pedicle cutting. [0003] There are two traditional methods of blood flow occlusion: [0004] 1. The rubber band method, the specific method is to tighten the pedicle of the flap with a rubber band, and then clamp the joint of the rubber band with a vascular forceps. Some scholars improved it by adding a sleeve between the flap pedicle and the hemostat; [0005] 2. Intestinal forceps method, the specific method is to directly clamp the pedicle of the flap with intestinal forceps. Some scholars have mad...

Problems solved by technology

[0006] The above two methods are similar, the advantages are convenient and fast, and the disadvantages are: (1) the pressure cannot be precisely controlled; (2) the blocking time cannot be set, and it needs to be stopped manually; (3) when the temperature of the flap is too low and the flap is endangered Automatic stop, need medical staff on duty
