Negative pressure micro-controlled portable drainage device

Abstract

The invention relates to medical equipment for drainage. Drainage can help swelling on wound surfaces to be alleviated smoothly, body fluids are discharged, and healing of the wound surfaces is facilitated. Bleeding amount of drainage changes along with change of negative pressure of drainage and is different according to body conditions of patients, and personalized adjustment is needed. A negative-pressure micro-control portable drainage device is characterized in that the appearance that a semicircular bottle body and a water drop ball-type drainage bottle are matched is adopted on a negative-pressure bottle body, the negative-pressure bottle body is provided with two bottle openings, a manual negative-pressure inflator is assembled in one bottle opening, a negative-pressure regulating valve is arranged on the other bottle opening, adjusted negative pressure is connected with a drainage bottle through a catheter, the drainage bottle is further provided with two bottle openings, one bottle opening is a drainage suction opening, the other bottle opening is an outer liquid outlet, and negative pressure adjustment is achieved in the mode that a pressure regulating arch membrane (2) expands or retracts by means of suction force generated by the negative pressure, an adjustable micro-control device is pushed, medical staff adjust the magnitude of the negative-pressure suction force according to conditions of patients and accordingly a required negative pressure value is obtained. The negative-pressure micro-control portable drainage device is low in cost, disposable, safe, hygienic, small in size, convenient to carry, needless of a power supply and easy to operate, and drainage pressure limiting is reliable.

Description

technical field [0001] The invention relates to a disposable micro-control drainage pressure limiting device. Background technique [0002] Clinically, patients need drainage after knee or hip surgery, so that the exudate, pus and exfoliated necrotic tissue in the drained area can be timely and thoroughly drawn out of the body, inhibit bacterial proliferation, control wound infection, reduce edema, and reduce blood vessels. Permeability, increase the blood supply of the wound, improve microcirculation, and promote tissue growth. When the drainage ball is draining, the bleeding volume changes with the negative pressure of the drainage ball. The patient's physical condition is difficult to control the bleeding volume, and the drainage device needs to be small and easy to carry , the size of the negative pressure must be effectively adjusted during drainage, and a one-time micro-controlled negative pressure drainage pressure limiting device is required.
