Abstract
The utility model discloses a disposable non-polyvinyl chloride (PVC) blood transfusion device, which comprises a drip chamber. One end of the drip chamber is connected with a puncture outfit, and the other end of the drip chamber is connected with a blood transfusion tube. A blood filtering device is arranged in the drip chamber. An air filter is arranged on an extended section outside the puncture outfit. The drip chamber is formed by the injection molding of a K-resin. The blood transfusion tube is formed by the extrusion molding of the K-resin. The drip chamber is formed by the injection molding of the K-resin, the blood transfusion tube is formed by the extrusion molding of the K-resin, and the K-resin is nontoxic, so that the generation of toxic substances is avoided in the drip chamber and the blood transfusion tube which are produced by the K-resin; and compared with the prior art, the blood transfusion device has the advantages of high safety performance and higher practicability.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to the non-PVC blood exchange transfusion set of a kind of disposable application formula.
Background technology
The critical piece of disposable transfusion set is dropping funnel and blood transfusion tube, dropping funnel, these two kinds of plastics of blood transfusion tube directly with the blood exchange transfusion set in blood contact, when producing this base part; The traditional injection moulding raw materials technology adopts soft PVC resin (polyvinyl chloride resin), but contains the plasticizer of phthalate in the flexible PVC resin, when using such blood exchange transfusion set; Phthalate can get into human body together with blood, and phthalate plays the effect of similar estrogen in human body and animal body, can disturb endocrine; Have a strong impact on male patient's reproductive function; The influence factor is bigger to child patient, if stripping quantity surpasses level of security in the blood transfusion process, can endanger child's liver and kidney; Also can cause children's sexual precocity, bring potential safety hazard to use.
The utility model content
The purpose of this utility model is to address the above problem; Provide a kind of disposable application formula non-PVC blood exchange transfusion set, utilize the avirulence of the transparent anti-impact resin of butylbenzene (K-resin), adopt this raw material production dropping funnel and blood transfusion tube; Can not produce noxious substance, have high with the practical more advantage of security performance.
The purpose of this utility model is to realize through following technical scheme:
The non-PVC blood exchange transfusion set of a kind of disposable application formula; Comprise dropping funnel, said dropping funnel one end connects perforator, and the other end connects blood transfusion tube; The set inside blood filter device of said dropping funnel; The outside extension of said perforator is equipped with air filter, and said dropping funnel is by the K-resin injection molding, and said blood transfusion tube is by the K-resin extrusion molding.
The outside extension of said perforator outer race is provided with protective sleeve, and the junction outside injection moulding of said perforator and dropping funnel is welded with a welding circle.
Order is provided with flow regulator, liquid injecting piece on the said blood transfusion tube, and the end of said blood transfusion tube is provided with entry needle.
Said entry needle links to each other with the end of said blood transfusion tube through an outer cone joint, and the head of said entry needle is provided with pinhead sleeve, and said outer cone joint is provided with helmet.
The beneficial effect of this utility model is: the dropping funnel of this utility model is by the K-resin injection molding; Blood transfusion tube is by the K-resin extrusion molding; Utilize the avirulence of K-resin, adopt this raw material production dropping funnel and blood transfusion tube, can not produce noxious substance; The contrast prior art, this blood exchange transfusion set has high with the practical more advantage of security performance.
