Abstract
The utility model relates to the field of medical equipment, in particular to a dialysis pipeline connecting device, which comprises a main pipe, wherein two ends of the main pipe are respectively connected with a connecting pipe, the side part of the main pipe, which is positioned on the connecting pipe, is connected with a retaining ring, a sleeve pipe is connected between the connecting pipe and the retaining ring, the sleeve pipe is rotationally connected on the main pipe, and an internal thread is arranged in the sleeve pipe; the device is used for solving the problems that the blood can not be returned quickly and the dialyzer can not be replaced safely in advance when sudden events such as blood coagulation of the hemodialyzer, membrane rupture of the dialyzer, rupture of the dialyzer and the like occur in the hemodialysis.
Description
Technical Field
The utility model relates to a medical treatment field, concretely relates to dialysis pipeline connecting device.
Background
The hemodialysis pipeline is used for connecting a hemodialyzer and is divided into an arterial segment and a venous segment. The front pipeline of the hemodialyzer is an arterial segment, and the rear pipeline of the hemodialyzer is a venous segment. Current emergencies in hemodialysis include: the blood coagulation of a dialyzer, the membrane rupture of the dialyzer and the rupture of the dialyzer are achieved, and at present, the clinical hemodialysis nurse treatment method is that a new dialyzer is connected with an extracorporeal circulation pipeline but cannot achieve safe pre-flushing, so that the risk of thrombus and infection is easily caused.
Disclosure of Invention
The utility model provides a not enough to prior art, the utility model provides a dialysis pipeline connecting device for can not return the problem of blood fast when having emergency in solving hemodialysis, effectual extracorporeal circulation connection has been established that can be quick.
The technical scheme of the utility model is realized like this: the utility model provides a dialysis pipeline connecting device, is including being responsible for, and the both ends of being responsible for are connected with the connecting pipe respectively, and the lateral part that just is located the connecting pipe on being responsible for all is connected with the retaining ring, is connected with the sleeve pipe between connecting pipe and the retaining ring, and the sleeve pipe rotates to be connected on being responsible for, and the intraductal internal thread that is provided with of cover.
The diameter of the connecting pipe is larger than that of the main pipe.
And a sealing ring is arranged in the sleeve.
The two sides of the outer part of the sleeve are connected with handles.
The sleeve is connected with a sealing cover in a threaded manner, and the main pipe is filled with physiological saline.
The technical scheme of the utility model has following positive effect: the device comprises a sealing cover for sealing the physiological saline, wherein the sealing cover is removed when the device is used, two ends of a main pipe are connected with connecting pipes, the connecting pipes can be quickly connected with an artery joint and a vein joint of a dialysis pipeline, then a sleeve pipe is rotated, the sleeve pipe is in threaded connection with the artery joint and the vein joint, so that the main pipe is respectively and fixedly connected with the artery joint and the vein joint, and a sealing ring prevents blood leakage; the sleeve pipe is connected with the handle, so that medical personnel can be conveniently and quickly connect the sleeve pipe with the artery joint and the vein joint, the sleeve pipe can be directly used under emergency, the operation method is simple, the training is facilitated, the clinical risk is reduced, and the nursing safety factor is improved.

Detailed Description
As shown in fig. 1 to 4, a dialysis pipeline connecting device, including being responsible for 1, the both ends of being responsible for 1 are connected with connecting pipe 2 respectively, be responsible for 1 and connecting pipe 2 UNICOM, connecting pipe 2 and being responsible for 1 body coupling, the lateral part that just is located connecting pipe 2 on being responsible for 1 all is connected with retaining ring 3, be connected with sleeve pipe 4 between connecting pipe 2 and the retaining ring 3, sleeve pipe 4 rotates to be connected on being responsible for 1, be provided with the internal thread in the sleeve pipe 4, connecting pipe 2 and retaining ring 3 play the effect of blockking to sleeve pipe 4.
The diameter of the connecting pipe 2 is larger than that of the main pipe 1, the sleeve 4 is rotatably connected to the main pipe 1, and the connecting pipe 2 plays a role in blocking.
The sleeve 4 in be provided with sealing washer 5, sealing washer 5 prevents the seepage.
The both sides of the outside of sleeve pipe 4 be connected with handle 6, handle 6 makes things convenient for medical personnel to operate.
The sleeve pipes 4 are all in threaded connection with sealing covers 11, and the main pipe 1 is filled with physiological saline; when the device is used, the sealing cover 11 on one side is screwed off, the sleeve 4 on one side is connected with the arterial connector 9, the sealing cover 11 on the other side is screwed off, the sleeve 4 on the other side is connected with the venous connector 10, and the physiological saline machine is communicated with the arterial tube 7 and the venous tube 8.
The working principle is as follows: in the process of hemodialysis, if sudden conditions of blood coagulation of a dialyzer, membrane rupture of the dialyzer and rupture of the dialyzer occur, a blood pump is turned off, the failed dialyzer needs to be quickly discarded, and then the device is installed, as shown in fig. 3; the sealing cover 11 on one side is firstly screwed off, the sleeve 4 on one side is connected with the arterial connector 9, the sealing cover 11 on the other side is screwed off, the sleeve 4 on the other side is connected with the venous connector 10, so that the physiological saline can be communicated with the arterial connector 9 and the venous connector 10, the quick connection is realized, the blood is safely returned, the blood loss of a patient is reduced, and medical staff can further prepare and safely pre-flush a new dialyzer.
