The air squeezed in the process enters the air bag 12 through the U-shaped tube 8 and the one-way valve 13, the air bag 12 is expanded immediately, and the air bag 12 can be further in close contact with the skin of the patient through expansion, more specifically, the air bag 12 can be in close contact with the skin of the patient, which is near to the stoma, on the abdomen of the patient, the dialysis catheter 9 is inserted into the abdomen of the patient, so that the sealing of the stoma is ensured, the body fluid exudation at the stoma is reduced, and the secondary infection is avoided; by means of expansion and extrusion of the air bag 12, the abdominal stoma of the patient can be further plugged, and meanwhile, the position of the dialysis catheter 9 is reinforced, so that the dialysis catheter 9 is prevented from shaking at the stoma;
after extrusion is completed, more than half of air in the box body 2 is transferred, at the moment, the two shift levers 4 are reset and rotated, so that the two shift levers 4 rotate towards the direction away from the dialysis catheter 9, at the moment, the piston plate 3 can move downwards in the box body 2, the space in the box body 2 is increased, the box body 2 can be in a negative pressure environment, the air in the cover body two 11 can be sucked and transferred into the box body 2 through the check valve two 14, the air in the cover body two 11 is transferred, the interior of the cover body two is in the negative pressure environment, the cover body two 11 can be tightly fixed on the abdomen of a patient through negative pressure adsorption, the whole fixing of the device is further realized, and the extrusion, sealing and isolation of the air bag 12 are realized, so that dirty liquid at a stoma can not be sucked into the cover body two;
the working principle is as follows: when the peritoneal dialysis positioning device for nephrology department is used, the front end of the dialysis catheter 9 is aligned and arranged on the abdomen of a patient; after the dialysis catheter 9 is accurately inserted, the dialysis catheter 9 is further inserted into the abdomen of the patient, so that the front sides of the first cover body 10 and the second cover body 11 are attached to the skin of the abdomen of the patient; then, the two shift levers 4 are manually operated, so that the two shift levers 4 are continuously closed to the dialysis catheter 9 through rotation, and in the rotation process, the piston plate 3 can move upwards in the box body 2, so that air in the upper space of the box body 2 is continuously extruded, and the extruded air can enter the U-shaped pipe 8 through the elastic hose 6; because the first check valve 13 and the second check valve 14 in the U-shaped pipe 8 guide air oppositely, the air can only enter the air bag 12 in one way through the arrangement of the first check valve 13, and the air can only flow out of the second cover body 11 in one way through the arrangement of the second check valve 14; the air squeezed in the process enters the air bag 12 through the U-shaped tube 8 and the one-way valve 13, the air bag 12 is expanded immediately, and the air bag 12 can be further in close contact with the skin of the patient through expansion, more specifically, the air bag 12 can be in close contact with the skin of the patient, which is near to the stoma, on the abdomen of the patient, the dialysis catheter 9 is inserted into the abdomen of the patient, so that the sealing of the stoma is ensured, the body fluid exudation at the stoma is reduced, and the secondary infection is avoided; by means of expansion and extrusion of the air bag 12, the abdominal stoma of the patient can be further plugged, and meanwhile, the position of the dialysis catheter 9 is reinforced, so that the dialysis catheter 9 is prevented from shaking at the stoma; after extrusion is completed, more than half of air in the box body 2 is transferred, at the moment, the two shift levers 4 are reset and rotated, so that the two shift levers 4 rotate towards the direction away from the dialysis catheter 9, at the moment, the piston plate 3 can move downwards in the box body 2, the space in the box body 2 is increased, the box body 2 can be in a negative pressure environment, the air in the cover body two 11 can be sucked and transferred into the box body 2 through the check valve two 14, the air in the cover body two 11 is transferred, the interior of the cover body two is in the negative pressure environment, the cover body two 11 can be tightly fixed on the abdomen of a patient through negative pressure adsorption, the whole fixing of the device is further realized, and the extrusion, sealing and isolation of the air bag 12 are realized, so that dirty liquid at a stoma can not be sucked into the cover body two; through the cooperation use between the above-mentioned structure, solved in the in-service use process, because traditional being used for nephrology dept peritoneal dialysis locator exists and lacks sealing device, the installation positioning device process is more troublesome, the poor problem of fixity.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
