Description

Blood purification circulation pipeline vein kettle capable of simultaneously injecting multiple medicines

Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a blood purification circulation pipeline venous pot capable of injecting various medicines simultaneously.

Background

Chronic kidney disease has become a global public health problem and more uremic patients must receive hemodialysis or kidney transplant treatments. It is conservative estimated that if the hemodialysis cost per 100 million uremic patients is about 400 yuan (400 yuan per Shanghai's standard of charge), 2.51 times per week (Shanghai's average data), about 130 treatments are required per year, and 5.2 yuan per year (52 weeks), the capacity of the hemodialysis service market in China will exceed 500 million yuan. The demand of the blood purification circulation pipelines reaches 1.3 hundred million, and the price of each pipeline terminal is calculated according to about 25 yuan, so that the market of the blood purification circulation pipelines in China exceeds 30 million yuan every year.

Blood purification is also called dialysis in daily life. Its meanings are: the blood of the patient is led out of the body and passes through a purifying device to remove some pathogenic substances and purify the blood, thereby achieving the purpose of treating diseases. The blood purification should include: hemodialysis, hemofiltration, hemoperfusion, plasmapheresis, immunoadsorption, etc. Peritoneal dialysis does not draw blood out of the body, but the principle is the same. Hemodialysis is only one of the methods for treating chronic renal failure.

Hemodialysis utilizes the principle of a semipermeable membrane to remove various harmful and redundant metabolic wastes and excessive electrolytes in the body by diffusion and convection so as to achieve the aim of purifying blood and achieve the aim of correcting water electrolyte and acid-base balance by absorption.

The principle of blood perfusion is to draw the blood of a patient out of the body, contact the blood with a solid adsorbent (such as resin in an HA resin blood perfusion device), remove certain metabolites, exogenous drugs or poisons and the like in the body in an adsorption mode, and then return the purified blood to the patient, thereby achieving the purpose of treating diseases.

The blood purification pipeline is used as a pipeline channel for conveying blood and liquid medicine. The pipeline is divided into a pipeline with a pump pipe, a pipeline without a pump pipe and a local connecting pipe according to the structure.

The pipeline with the pump pipe mainly comprises a guide pipe, a dialyzer connector, an injection piece, an injection head, an injection connector, an air pot, a pump pipe, a T-shaped connector, a flow regulator, a regulating clamp, a connector, a bottle stopper puncture device, a filter screen, a pressure measuring block, a heating bag, a sensor protector, a shield and a handle.

The pump-free pipeline mainly comprises a conduit, a dialyzer connector, an injection piece, an injection head, an injection connector, an air pot, a T-shaped connector, a flow regulator, a regulating clamp, a connector, a bottle stopper puncture outfit and a filter screen.

Many patients with chronic hemodialysis have the possibility of hypocalcemia caused by the fact that parathyroid hormone is too high and parathyroid gland surgical excision is needed, so doctors prescribe continuous calcium pumping within 4 hours of dialysis. Because the calcium gluconate is a micromolecular drug, in order to ensure that the drug is not purified and the drug effect is ensured, the drug is slowly and continuously applied from the venous pot end; the currently used blood purification pipeline only has one medicine injection joint and is already occupied, so that when other medicines need to be pumped in some emergency situations, corresponding channels are lacked, a lot of inconvenience is caused, and the blood purification circulation pipeline venous pot capable of simultaneously injecting various medicines is needed.
