Peritoneal dialysis sterile connecting device

Abstract

The present invention discloses a peritoneal dialysis sterile connecting device. The peritoneal dialysis sterile connecting device comprises a sterile connection operation box and a clamping and fixing seat for clamping and fixing a cylindrical transition part of a connector of an external short pipe; and the sterile connection operation box is made of transparent materials and the clamping and fixing seat is fixedly arranged in the sterile connection operation box. The sterile connection operation box provides a sterile operation space, so that a peritoneal dialysis solution pipe and the external short pipe can be accommodated in the sterile connection operation box for connection, so that the peritoneal dialysis solution pipe and the external short pipe are both difficult to pollute by touching of foreign objects or adhering of outside dust, etc., the clamping and fixing seat is suitable for clamping and fixing the cylindrical transition part of the connector of the external short pipe and can play an effect of a third hand to help pull out an iodophor cap at a threaded connection part of the connector of the external short pipe and help connect the external short pipe and the peritoneal dialysis solution pipe, so that compared with traditional operation methods, the manner adopted by the peritoneal dialysis sterile connecting device does not easily cause problems that the connector of the external short pipe is polluted in advance and a pipe head of the peritoneal dialysis solution pipe is polluted in advance, and therefore, the peritoneal dialysis sterile connecting device is good in pollution prevention effect when in use.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a peritoneal dialysis aseptic connecting device. Background technique [0002] Peritoneal dialysis (PD) is a dialysis method that uses the body's own peritoneum as the 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, removes the metabolites and excess water retained in the body, and at the same time replenishes the body’s essential substances through the dialysate. Through continuous renewal of peritoneal dialysis fluid, the purpose of renal replacement or supportive treatment can be achieved. [0003] In the existing life, many patients often perform peritoneal dialysis at home. When the patient needs peritoneal dialysis, it is necessary to connect the peritoneal dialysis fluid tube and the external short tube. Connect the end of the exter...

Problems solved by technology

[0004] For the above operations, it needs to be carried out under sterile conditions, otherwise, when the connector of the external short tube of the iodophor cap is removed and / or the peritoneal dialysis fluid tube head of the cap is contaminated, it is easy to cause The dialysate flowing through it is contaminated, which makes it easy to cause peritonitis and other complications to the patient and bring danger to the patient's life

[0005] The common disadvantages of the above-mentioned patients or their family members' home operations are: the patient or the patient's family members are not professionals, and their understanding of aseptic awareness is not comprehensive enough. Use their right hand to cooperate with their left hand to connect the end of the external short tube held by the left hand. When the iodophor cap outside the head is removed, the outer wall of the peritoneal dialysis tube head held by his right hand will easily touch the connector of the external short tube with the iodophor cap removed, so that the corresponding connector of the external short tube will be pre-installed. Similarly, when the left hand cooperates with the right hand to remove the cap at the head of the peritoneal dialysis fluid tube held by the right hand, the outer wall of the external short tube held by the left hand can easily touch the peritoneum from which the cap has been removed. Dialysate tube head, so that the corresponding peritoneal dialysis liquid tube head will also be pre-contaminated, and the sanitary environment at home is relatively poor compared to the hospital, and the aseptic connection operation of related peritoneal dialysis is also easily contaminated by foreign objects
