Abstract
A disposable medical blood sampling and transfusion device comprises a catheter with a filter belt and a needle head, wherein a blood sampling end is connected by a tee joint, an included angle between the central line of the needle head and the central line of a blood transfusion tube is an obtuse angle, and a feedback end is respectively connected with the transfusion needle head and the feedback tube by the tee joint. The blood collection and transfusion integrated device is compact in structure, integrates collection and blood transfusion, is disposable in each channel, is convenient, and effectively avoids pollution.
Description
This utility model relates to a kind of Dispoable medical that is used for the haemodialysis processing and adopts the blood exchange transfusion set.Its centralized procurement blood, transfuse blood in one.
At present, the disposable medical articles for use are applied to medical all departments more and more widely.Since the haemodialysis method was promoted, the promptly sick method of controlling from blood had been applied to clinical gradually.In haemodialysis, all need take a blood sample and transfuse blood.Existing blood exchange transfusion set's function singleness need be changed socket in use repeatedly, has increased opportunities for contamination, and needs in operation with interim controlled adjusters of heavy apparatus such as mosquito forcepss, very trouble.Existing hemostix function is also single, its major defect is that the angle between blood taking needle and Sheng blood container is an acute angle, when patient's vein blood flow during through this acute angle, blood flow rate die-offs and the blood coagulation obstruction very easily takes place, this had both increased the patient suffering, also owing to adopt, the blood exchange transfusion set each overlap with one and increase its financial burden.
The purpose of this utility model provides a kind of once medical blood exchange transfusion set of adopting, and its compact conformation, is transfused blood in one at centralized procurement, and the disposable use of each passage is both convenient, effectively avoids again polluting.
The purpose of this utility model is achieved in that this device comprises the conduit that has strainer, syringe needle, wherein the blood sampling end utilizes the blood collection needles centrage and the blood transfusion tube centreline space angle of threeway connection to be the obtuse angle, feeds back end and adopts threeway to join with infusion needle and feedback pipe respectively.
Because this utility model is the obtuse angle at the blood collection needles centrage and the blood transfusion tube centreline space angle of blood sampling end, venous blood flow blocks through being difficult for taking place blood coagulation herein during blood sampling, when thereby the angle of effectively avoiding prior art to exist is acute angle, the disadvantage that the easy blood coagulation of venous blood is blocked, reduce patient's misery, help the blood sampling treatment.Feed back in addition end adopt threeway with infusion needle, feed back pipe and join, when blood that feedback is handled, need not to change repeatedly again socket, easy to use, each passage once uses, and can prevent pollution.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure sketch map of this utility model.
Describe concrete structure of the present utility model in detail according to Fig. 1.This utility model both can be used as hemostix, again can be as collecting the blood exchange transfusion set that the blood of containing blood container feeds back after treatment again.It comprises that the conduit that has filter bag 4 reaches the syringe needle and blood transfusion tube 7, the feedback that are installed on it by threeway and manages 8.Wherein the blood sampling end utilizes blood collection needles 5 centrages of threeway 6 connections and the angle of blood transfusion tube 7 centreline spaces to be the obtuse angle, does not block to guarantee the blood of being gathered, and blood transfusion is smooth, alleviates patient's suffering of illness.If control plate holder 2 is installed on blood transfusion tube 7, then after containing the intact blood of blood container collection, can easily blood transfusion tube be clamped, and make interim actuator without mosquito forceps, reduce medical worker's heaviness operation.The blood of containing in the blood container disposes in the blood treatment instrument, the passage of containing blood container directly can be connected on feedback pipe 8 ends and feed back.And existing blood exchange transfusion set does not have the pipe of feedback, needs infusion needle is pulled out, and connects and changes socket, just can feed back, and its operation had both bothered, and polluted socket again easily.This device then can utilize threeway 3 to operate at the infusion needle 1 that feeds back the end setting, feedback pipe 8, and opens and closes passage at any time with the control plate holder 2 on it, need not mosquito forceps and makes interim actuator, and is convenient and healthy pollution-free again.
Claims (2)
1, a kind of Dispoable medical is adopted the blood exchange transfusion set, comprise the conduit that has strainer, syringe needle, the end that it is characterized in that taking a blood sample utilizes the blood collection needles centrage and the blood transfusion tube centreline space angle of threeway connection to be the obtuse angle, feeds back end and adopts threeway to join with infusion needle and feedback pipe respectively.
2, according to claim 1ly adopt the blood exchange transfusion set, it is characterized in that being equipped with respectively on each connecting duct the control plate holder.
