Description
Technical Field
The invention belongs to the technical field of dialysis auxiliary equipment, and particularly relates to dialysis auxiliary equipment for nephrology department.
Background
At present, hemodialysis is the most effective treatment method for kidney diseases, a dialysis device comprises a dialyzer, a dialysis tube and a dialysate supply system, the dialysate of metabolic waste and redundant moisture in a human body is released from the human body through an outer tube, then new hemodialysis liquid is filled, many patients choose to puncture the abdomen, and thus the hemodialysis tube needs to be fixed on the abdomen of the human body, so the fixation of the hemodialysis tube is particularly important, if the hemodialysis tube is carelessly dragged, the treatment is troublesome, meanwhile, the patients are painful, in addition, the general fixing device is tightly contacted with the skin of the human body, the skin around the wound has poor air permeability, the skin can be fixed for a long time, the phenomena of skin allergy and the like can be caused, no disinfection measures are provided around the wound, the wound infection can be caused by carelessness, and various hemodialysis tube fixing devices are designed for solving the problem, however, most of the fixing devices have small fixing area for the catheter, and the fixing effect is not obvious.
The prior art also discloses some technical schemes related to dialysis auxiliary equipment, for example, Chinese patent with application number 2018216625618 discloses a dialysis tube fixing device for nephrology department, which inserts a dialysis tube into an air bag ring through the matching arrangement of the air bag ring, an inflation inlet and a cap, inflates the air bag ring to enlarge the air bag ring to extrude the dialysis tube, when the dialysis tube is fixed firmly, the inflation is stopped, the cap is covered, dialysis tubes with different diameters can be fixed according to the inflation amount, the operation is simple and convenient, the fixation is firm, through the arrangement of the air holes, when a fixed disk contacts with the skin, the fluidity of air can be increased, thereby avoiding discomfort brought to a patient during long-time dialysis, achieving the purposes of being suitable for air tubes with different diameters, being simple in operation and firm in fixation, but when the dialysis tube is clamped in an auxiliary way, the dialysis tube is inserted into the flexible air bag ring, then air is injected into the hollow flexible air bag ring, so that the flexible air bag ring is expanded, the dialysis tube is clamped, at the moment, the air is gradually injected into the air bag ring, the air filling time is longer, the air bag ring is required to be plugged after the air is filled, the use time is further prolonged, the waiting time of a patient is longer, and the dialysis treatment on the patient cannot be timely carried out.
Disclosure of Invention
In view of the deficiencies of the prior art, the present invention provides a dialysis auxiliary device for nephrology department, so as to solve the problems mentioned in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: a dialysis auxiliary device for nephrology department comprises an outer fixing ring and a contact part connected to the rear side face of the outer fixing ring, wherein an annular plate is arranged in the middle of the inner side of the wall thickness of the outer fixing ring, a plurality of diaphragms are uniformly distributed on the top of the annular plate along the circumferential direction, a lower pressing rod is connected to the bottom of each diaphragm and penetrates through the annular plate, an elastic plate is arranged at the bottom of each lower pressing rod, one end, close to the outer surface of the outer fixing ring, of each elastic plate is fixedly connected with the inner wall of the outer fixing ring, and one end, close to the inner; the top of the outer fixing ring is provided with an elastic ring which is fixedly connected with the inclined plate; the top of the outer fixing ring is inserted with a rubber plug, and the outer fixing ring at the rubber plug is provided with a tensioning strip which is used for fixing the rubber plug; two ribbons are arranged on one side of the outer fixing ring; when the dialysis tube clamping device works, the dialysis tube is inserted into the flexible air bag ring when the dialysis tube is clamped in an auxiliary mode by the existing dialysis auxiliary equipment, then air is injected into the hollow flexible air bag ring, so that the flexible air bag ring is expanded and the dialysis tube is clamped, at the moment, the air is gradually injected into the air bag ring, the air is filled for a long time, the air bag ring is required to be plugged after the air is filled, the using time is further prolonged, the waiting time of a patient is long, and the patient cannot be subjected to dialysis treatment in time, so that the dialysis tube clamping device mainly solves the problem that the dialysis tube is rapidly clamped when the patient needs dialysis, the waiting time of the patient is shortened, and the timeliness of the treatment is improved; the specific measures and the using process are as follows: in the preparation stage, after the rubber plug is used for the last time, gas is filled into the outer fixing ring at the top of the annular plate from the rubber plug, the filled gas pushes the diaphragm to expand downwards, the lower pressing rod is further pushed, the lower pressing rod downwards extrudes the elastic plate, the elastic plate is deformed downwards, the end part of the inclined plate fixedly connected with the elastic plate is pulled to be close to the outer surface of the outer fixing ring, the top ends of the inclined plates are further gradually far away, and the elastic ring is further pulled, so that the diameter of the elastic ring is increased; the medical rubber plug is inserted into the top of the outer fixing ring again until the diameter of the elastic ring is not easy to change any more, so that the preparation stage is in a period of time when no patient conducts dialysis, the medical rubber plug is stored after the preparation stage is completed, when the medical rubber plug is pulled out, the elastic ring can be quickly restored to fix the dialysis tube, the dialysis tube is quickly clamped, the waiting time of the patient is shortened, and the timeliness of treatment is improved.
A plurality of notches are formed in the two auxiliary baffles on the same rotating plate, the auxiliary baffles are divided into a plurality of sections by the notches, the adjacent two sections are hinged, elastic ropes are arranged at the openings of the notches, and two ends of each elastic rope are respectively connected to the adjacent two sections of the auxiliary baffles; when the elasticity circle recovers to fix the dialysis tubing, during the inclined plate upward movement, the swash plate can drive and connect the rope bottom and rise, it drives the rotor plate upwards to connect the rope, when the rotor plate deflects, the rubber slab of rotor plate tip can upwards deflect, and then can drive the dialysis tubing of contact position department and upwards remove partly, make the dialysis tubing that has one section snake shape between elasticity circle and the rubber slab, when the dialysis tubing bottom receives the pulling, the dialysis tubing of snake shape can straighten earlier this moment, the dialysis tubing that makes the bottom can have certain displacement, when preventing that the bottom from receiving the pulling, cause the removal of the dialysis tubing of elasticity circle department, the stability of the dialysis tubing at top has been guaranteed.
