Description

Y-shaped multifunctional hemodialysis circulating pipeline

Technical Field

The utility model relates to the field of hemodialysis pipelines, in particular to a Y-shaped multifunctional hemodialysis circulating pipeline.

Background

Hemodialysis is a renal replacement therapy commonly used in patients with renal failure; during hemodialysis, a patient establishes extracorporeal blood circulation through a circulation line; the blood-leading section (artery end) of the pipeline leads the blood on the patient body to the outside of the body under the action of a hemodialysis machine power pump, then flows through the dialyzer, and the blood purified by the dialyzer returns to the patient body through the blood-returning section (vein end) of the pipeline, so that a continuous closed hemodialysis extracorporeal circulation process is formed.

Intradialytic hypotension is one of the most common acute complications of hemodialysis. The patient has hypotension during the hemodialysis process, and the clinic carries out the operation of quickly supplementing physiological saline through extracorporeal circulation on the patient: usually, the infusion apparatus is used in combination, one end of the infusion apparatus is connected with the saline bag, the other end (without a scalp needle) is connected with the arterial end pre-flushing side tube (the side branch tube in front of the power pump), and under the action of the power pump, saline is quickly supplemented into the tube through the infusion apparatus and then returns to the body of a patient, so that the purpose of quickly supplementing and boosting the pressure is achieved.

After the hemodialysis of the patient is finished, the clinic will perform a blood returning and off-machine operation, i.e. the physiological saline is used to return the blood in the extracorporeal circulation to the patient. The operation process is as follows: 1. using an infusion set, connected as described above; 2. opening a pre-flushing side tube at the arterial end, and returning blood remained in the arterial side tube for 20-30 s by using saline water; 3. the blood pump is closed, and the blood at the proximal side of the artery side tube is infused back into the body of the patient by means of gravity; 4. clamping an arterial pipeline clamp, starting a blood pump, and returning blood in the whole process by using saline; 5. and (5) removing the pipeline after blood returning is finished.

The sufficient blood flow at the arterial end and the unobstructed blood loop at the venous end are the prerequisites for ensuring the smooth hemodialysis. Some patients have insufficient blood flow at the arterial end due to a plurality of reasons such as blood vessel fineness, lumen stenosis, thrombus formation in the blood vessel, thrombus formation in the catheter, and fibrin sheath formation around the catheter, so that the hemodialysis quality is reduced, and even the hemodialysis treatment cannot be smoothly carried out. The clinic will often choose a new vascular access replacement. But if there is no ideal path to replace it completely, it is also an alternative to add blood flow to the arterial end with a parallel blood vessel. The operation method comprises the following steps: the 16# internal fistula needle is used for successfully puncturing a vein, then a connecting pipe is used for connecting the internal fistula needle with the arterial end preflush side pipe, and blood of the internal fistula needle is merged into a main pipeline of the arterial end, so that the blood flow of the arterial end is increased.

In summary, the following technical problems exist in the hemodialysis process of the current patients: 1) the condition of low blood pressure occurs in the hemodialysis process, the emergency treatment of quickly supplementing saline is clinically carried out on a patient, an infusion apparatus needs to be connected, but the inner diameter of the infusion apparatus is small, the tube wall is thin, the pipeline can be deflated under the negative pressure of a power pump, the saline supplementing speed is relatively slow, part of the infusion apparatus is packaged separately and needs to be manually connected with a pre-flushing side tube at the arterial end, the operation time is consumed, and the possibility of polluting a connector is increased; 2) after hemodialysis is finished, blood in an extracorporeal circulation pipeline needs to be returned to a patient, and an infusion apparatus is usually connected, so that the problems are the same as the above; 3) in the hemodialysis process, the condition that artery end blood flow is not enough can appear to some patients, as emergency treatment, can puncture a vein again in clinical, with a connecting pipe, with the internal fistula needle of new puncture and the arterial end preflush side union coupling of extrinsic cycle pipeline, merge the blood of this internal fistula needle into artery end main line. The problem with this operation is that: at present, a connecting pipe which is not matched with the medical device is not used clinically, and a nurse often selects a replacement liquid connecting pipe, so that the pipe is expensive, the cost is increased, and the operation time and the possibility of interface pollution are increased in the connecting process.
