Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a detachable sterilization operation air bag for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis is a type of dialysis that uses the body's own peritoneum as a dialysis membrane. The dialysate infused into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum to remove metabolic products and excess water retained in the body. At the same time, the dialysate replenishes the body's necessary substances. By continuously renewing the peritoneal dialysis fluid, the purpose of renal replacement or supportive therapy is achieved. In current clinical operations, patients who decide to undergo peritoneal dialysis will have a peritoneal dialysis catheter surgically inserted by a doctor to introduce and export the dialysate. Since most patients undergoing peritoneal dialysis are currently treated at home and follow up after discharge based on their condition and treatment needs, after the catheterization is completed, patients need to gradually learn and master the operating methods and precautions of peritoneal dialysis under the guidance of a peritoneal dialysis specialist nurse, including: routine operations of peritoneal dialysis fluid exchange, how to measure and record the infusion, drainage and ultrafiltration volumes, how to deal with unexpected situations, etc.

[0003] Currently, when peritoneal dialysis patients perform dialysis at home, they need to connect the connection tube reserved in the body to the external dialysis pipeline. The connection process cannot ensure sterile operation, and the dialysis pipeline is easily contaminated, which in turn causes the patient to be easily infected. For this reason, we propose a more practical detachable sterilization operation airbag for peritoneal dialysis. Summary of the invention

[0032] Working principle: For this type of detachable sterilization operation airbag for peritoneal dialysis, the airbag body 1 is mainly composed of two layers of material, namely the outer protective layer 2 and the inner membrane layer 3. The outer protective layer 2 mainly protects the inner membrane layer 3. The inner membrane layer 3 is thin and easy to tear. First, unscrew the exhaust pipe sealing rubber cap 18 in the exhaust pipe 16, and then connect the left end of the exhaust pipe body 17 to the external exhaust device, start the exhaust device, so that a pulling force outward is generated on the left side of the exhaust pipe body 17. The pulling force pulls the exhaust pipe baffle 22, and the exhaust pipe baffle 22 drives the exhaust pipe reset spring 21 to extend. The exhaust pipe reset spring 21 is fixed to the inside of the exhaust pipe body 17 through the exhaust pipe transverse fixing plate 20. At the same time, the exhaust pipe reset spring There are gaps between the spring 21 and the exhaust pipe transverse fixing plate 20 and the exhaust pipe body 17, which will not hinder the discharge of air. The exhaust pipe baffle 22 is separated from the pipe opening of the exhaust pipe body 17, resulting in a gap, and the air inside the inner film layer 3 is discharged along the exhaust pipe body 17. When the exhaust device is not working, due to the strong external atmospheric pressure and the exhaust pipe return spring 21 being in an extended state, a reverse force will be generated, so the exhaust pipe baffle 22 will immediately return to its original position, blocking the pipe opening of the exhaust pipe body 17 to prevent air from being re-sucked into the inner film layer 3, and then the exhaust pipe sealing gasket 19 is put on the outside of the exhaust pipe body 17, and then the exhaust pipe sealing rubber cap 18 is tightened to complete the sealing of the exhaust pipe 16;

[0033] Then, unscrew the inflation tube sealing rubber cap 9 in the first inflation tube 7, so that the inflation tube main body 8 is connected to the external inflation device, and the external inflation device is started. The air pressure passes through the inside of the inflation tube main body 8 and presses to one side of the inflation tube baffle 13, so that the inflation tube baffle 13 drives the inflation tube return spring 12 to extend. Since the inflation tube return spring 12 is fixed to the inside of the inflation tube main body 8 by the inflation tube transverse fixing plate 11, and there is a gap between the inflation tube return spring 12 and the inflation tube transverse fixing plate 11 and the inflation tube main body 8, it will not block the gas from being filled into the inner membrane layer 3, and the inflation tube baffle 13 and the inner pipe opening of the inflation tube main body 8 are separated. , a gap is generated, and the gas is filled into the inner film layer 3 through the gap. When the external inflation device is closed, the inflation tube baffle 13 will immediately retract under the elastic force of the inflation tube reset spring 12, and then block the pipe opening of the inflation tube body 8. At the same time, the inflation tube sealing strip 14 will fill the gap between the inflation tube baffle 13 and the inner film layer 3 to enhance the sealing effect. Then, the inflation tube sealing gasket 10 is put on the outside of the inflation tube body 8, and then the inflation tube sealing rubber cap 9 is tightened to complete the sealing of the first inflation tube 7. The second inflation tube 15 is operated in the same way, and ethylene oxide sterilizing gas is filled into the sterilizing gas containing chamber 4 through the second inflation tube 15, and then the seal is tightened;

[0034] The above steps are all completed during production, and when the patient uses it, the operation is mainly carried out through the following steps. The patient's hands are first placed in the two retracted recessed areas 23 respectively, and then the hands and the dialysis tubing are stuffed between the shrink sleeve 24, so that the outer protective layer 26 of the shrink sleeve is in contact with the patient's arm skin, and the elastic rope 25 is in an extended state and hoops the patient's arm. Then the patient's hands and the dialysis tubing are stuffed into the outer protective layer 2 from the channel 27. At this time, the inner membrane layer 3 is torn with force, and the inner membrane layer 3 is ruptured, and the internal gas is released, which will fill the entire airbag body 1. Then the rubber plug 6 is pulled outward to separate the rubber plug 6 from the sterilization gas holding chamber shell 5. The gas inside the sterilization gas holding chamber 4 will also be released and mixed with the inert gas to create a sterilization environment to sterilize the dialysis tubing. Then the patient can complete the connection of the dialysis tubing by observing the inside of the airbag body 1 through the outer protective layer 2 and the inner membrane layer 3. In this way, the use process of the detachable sterilization operation airbag for peritoneal dialysis is completed.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
