Description

Blood transfusion filter

Technical Field

The utility model relates to a blood filter equipment, in particular to blood transfusion filter.

Background

Transfusion and blood transfusion are one of the common and important medical means. After about 1-2 days of storage, white blood cells, platelets, fibrin, cell debris, denatured protein and the like in the blood form micro-aggregated particles with the diameter of 10-164 mu m, the number of the particles increases with the storage life, and larger fibrinogen-white blood cell-platelet aggregates form in the blood after 10 days. When transfused, these microparticles can enter the patient through a standard transfusion filter with a pore size of 170 μm, and can block capillaries. When large volumes of whole blood are transfused into the pool, these oligomers can widely occlude capillaries in the lungs, leading to pulmonary insufficiency, causing acute respiratory distress syndrome. When the extracorporeal circulation operation such as heart operation is carried out, the input whole blood and the micro-polymer in the blood components do not pass through the pulmonary circulation and directly reach the brain to cause the occurrence of cerebral embolism; in the existing blood transfusion process, particularly in winter, the blood is cool, so that the body of a patient receiving blood transfusion is uncomfortable, the existing means is generally to heat the blood outside firstly and then transfuse the blood, the steps are complicated and the operation is inconvenient, and even the blood cannot be pumped out for heating in emergency blood use, otherwise, the life safety of the patient is influenced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a blood transfusion filter has solved the problem of mentioning in the background art.

The utility model discloses a realize like this, a blood transfusion filter, this blood transfusion filter mainly by: casing, input port, output port, shunt tubes, filter equipment make up and form, input port sets up the upper end of casing, output port sets up the lower extreme of casing, input port with communicate through the shunt tubes between the output port, the shunt tubes is arranged in the inside of casing, filter equipment sets up on the shunt tubes, shunts blood through the shunt tubes, filters from the pipeline of difference, has avoided common filter to take place the not smooth problem of blood transfusion easily, and the shunt tubes also is arranged in simultaneously and is guaranteed to be heated evenly in the stock solution intracavity.

The utility model discloses a further technical scheme is: the shunt tubes are divided into a first branch and a second branch, the first branch and the second branch are respectively provided with a first filter element and a second filter element, and the double filter elements can ensure the filtering effect and guarantee the smoothness of blood transfusion.

The utility model discloses a further technical scheme is: the input port is provided with a first check valve, and the first check valve needs to be opened first during operation.

The utility model discloses a further technical scheme is: and the output port is provided with a second stop valve, and the second stop valve is opened for blood transfusion after the blood in the shunt tube is fully stored.

The utility model discloses a further technical scheme is: and the left end of the shell is provided with a water delivery pipe outlet for discharging circulating water.

The utility model discloses a further technical scheme is: the right end of the shell is provided with a water delivery pipe inlet for inputting circulating water.

The utility model discloses a further technical scheme is: the water storage cavity is arranged inside the shell and is respectively communicated with the water delivery pipe inlet and the water delivery pipe outlet, so that input liquid is temporarily kept in the shell.

The utility model discloses a further technical scheme is: the water pipe inlet and the water pipe outlet are both provided with plugging heads which are rubber heads and can be broken when in use, so that the cost is low.

The utility model has the advantages that: the utility model discloses a blood transfusion filter simple structure, low in production cost is honest and clean, the first filter core of accessible filters blood with the second filter core and reaches filterable effect and shunt blood and adopt two filter cores to filter and reduce because the not smooth condition of blood transfusion that the filter core blockked up and cause takes place, and can infuse required hot water to its inside through simple water storage chamber, can make blood heat in filterable while, two steps go on simultaneously, not only reduced medical personnel's work load and also practiced thrift operating time simultaneously, the comfort level of patient has been improved when having saved a large amount of valuable time.
