Abstract
The utility model relates to a disposable effective blood infusion device. At least a common blood filter and an effective blood filter for eliminating white blood cells are arranged on a blood pipeline which is arranged between an upper and a lower needle tubes, an adjustable clamp is arranged on the outlet tube of the effective blood filter, the effective blood filter is a PVC tube, non-toxic chemical fiber is filled in the PVC tube, the chemical fiber can be one kind or more than one kind of chemical filament, non-woven fabrics and sprayed fabrics, and both the inlet and the outlet of the effective blood filter are provided with nylon nets. The white blood cell and blood platelet eliminating rates of the device are high, red blood cell and blood plasma infusion rates are more than 99%, and fat and minimum fine particles can be removed. The utility model also has the advantages of simple manufacturing technology and low cost.
Description
This utility model relates to a kind of disposable efficient blood exchange transfusion set, belongs to medical apparatus and instruments.
Blood transfusion must be similar blood, should do match and join the type chemical examination before blood transfusion, to guarantee transfusion safety.Join type but generally only do erythrocyte at present, leukocyte and platelet are not all joined type, but adopt the blood exchange transfusion set be provided with leucocyte filter, make leukocyte in the blood and platelet before the input human body by filtering.Blood exchange transfusion set's manufacturing process complexity of existing this band leucocyte filter costs an arm and a leg as disposable use, and the patient is difficult to bear, and every pair of blood exchange transfusion set can only filter 200ML blood, and erythrocyte and blood plasma input rate can only reach 80-90%.
The purpose of this utility model provides a kind of disposable efficient blood exchange transfusion set, and its manufacturing process is simple, and cost is low, and erythrocyte, blood plasma input rate and leukocyte removal efficiency all are higher than existing similar blood exchange transfusion set.
There are the blood of drawing needle tubing and needle for inserting bottle pipe in this utility model blood exchange transfusion set upper end, there is the blood transfusion needle tubing lower end, a common hemofilter and one are housed on the transducer potector between the needle tubing up and down at least are used for removing leukocytic efficient hemofilter, on the outlet of efficient hemofilter adjustable clamp is housed, said efficient hemofilter is a pvc pipe, be filled with nontoxic chemical fibre in the pipe, said chemical fibre can be one or more in chemical fibre silk, non-woven fabrics, the fusion spray cloth, and nylon wire all is equipped with in the import and export of high efficiency filter; The outlet of efficient hemofilter is provided with bypass pipe, and the mouth of pipe of bypass pipe is provided with obstruction.
This blood exchange transfusion set can remove leukocyte more than 95%, and platelet is more than 80%, but also weeding of grease and minimum microgranule, manufacturing process is simple, and cost is low, and price is significantly less than existing similar blood exchange transfusion set.This blood exchange transfusion set erythrocyte and blood plasma input rate reach more than 99%, once can remove leukocyte and platelet in the 400ML blood.The defeated again 400ML blood behind the available normal saline flushing of being totally lost behind the 400ML blood, promptly one pair of blood exchange transfusion set can be to the defeated 800ML blood of same patient, be much higher than existing similar blood exchange transfusion set, normal saline after flushing is flowed out by bypass pipe together with compositions such as leukocyte and platelet, also can be used for making the interferon the like blood products after the collection.This blood exchange transfusion set also can make the erythrocyte oxygen content improve more than 50%.
Below in conjunction with description of drawings example structure of the present utility model.
Accompanying drawing is this disposable efficient blood exchange transfusion set's an example structure sketch map.
As shown in the figure, draw blood pin 1 and be used to introduce blood, needle for inserting bottle is used to insert saline bottle introducing flushing and uses normal saline, and adjustable clamp 3 and 4 are housed on the pipeline of the two lower end.In the common hemofilter 5 and 9 nylon wire 51 and 91 are housed respectively.Being filled with nontoxic chemical fibre silk 62 in the efficient hemofilter 6, also can be nontoxic non-woven fabrics or fusion spray cloth, and nylon wire 61 and 63 are equipped with in the import and export of efficient hemofilter respectively, and outlet has bypass pipe 7 and adjustable clamp 8, and the mouth of pipe of bypass pipe is equipped with and stops up 71.The top pipeline of blood transfusion needle tubing 11 is equipped with adjustable clamp 10.
This blood exchange transfusion set is disposable use, and pipeline and each filter shell all adopt the medical PVC pipe.Must use normal saline flushing before the blood transfusion of this device.
Claims (2)
1. disposable efficient blood exchange transfusion set, there are the blood of drawing needle tubing and needle for inserting bottle pipe in the upper end, there is the blood transfusion needle tubing lower end, a common hemofilter and one are housed on the transducer potector between the needle tubing up and down at least are used for removing leukocytic efficient hemofilter, on the outlet of efficient hemofilter adjustable clamp is housed, it is characterized in that said efficient hemofilter is a pvc pipe, be filled with nontoxic chemical fibre in the pipe, said chemical fibre can be one or more in chemical fibre silk, non-woven fabrics, the fusion spray cloth, and nylon wire all is equipped with in the import and export of high efficiency filter.
