The infusion set is safe to use, has a simple structure, and is convenient to operate and made of the environmental-friendly material. The phenomena of liquid leakage and needle slipping can be effectively prevented.
Description
Technical field
The invention belongs to medical instruments field, particularly relate to a kind of transfusion device that has the fastening-type joint.
Background technology
At present, the transfusion device accessory that uses in the medical treatment adopts the PVC material to form mostly, PVC needs to add multiple plasticizer and additive in forming process, these plasticizers and additive in use can ooze out, pollute medicinal liquid, also may generate harmful substance, damage patient's body health and therapeutic effect to a certain extent with medicinal liquid generation chemical reaction.In addition, contaminated soil is buried in the difficult processing of depleted PVC material, and burning then can produce hydrogen chloride with bioxin gas, and it then is carcinogen that hydrogen chloride can form acid rain ， bioxin.
A kind of brand-new material is arranged now---non-PVC material can substitute the PVC material and make the transfusion device assembly.But non-PVC material is not dissolved in usually the solvent in order to bonding PVC material, and the transfusion device assembly that causes non-PVC material the to be made installation that can't bond can't drop into clinical use on a large scale.
Summary of the invention
The present invention aims to provide a kind of transfusion device that has fastening, and it can solve the problem that transfusion device assembly that non-PVC material makes can't bond and install well, makes non-PVC material be widely used in delivery device.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of transfusion device comprises transfusion needle 1, conduit 5 and connects the joint 6 of transfusion needle syringe needle 2 and conduit 5 that joint inner surface 4 gradient α with transfusion needle syringe needle outer surface 3 gradient β pass are: α=β+(0 °～1.75 °).
Joint 6 is interior empty frustum cone structure, and its inner surface 4 gradients are 0.25 °～5.25 °.
Joint 6 is connected in the transfusion needle syringe needle by fixture 7.
Conduit 5 adopts non-PVC material to make.
Hollow structure is used to hold transfusion needle syringe needle 2 and conduit 5 in the joint 6, and transfusion needle syringe needle 2, conduit 5 and joint 6 threes' position is closed and is, transfusion needle syringe needle 2 inserts conduit 5 one ends, and joint 6 is wrapped in conduit 5 outsides and is connected on the transfusion needle syringe needle 2 by fixture 7.
Beneficial effect of the present invention is: 1, safe in utilization, non-PVC material does not contain dicarboxylic acid esters (salt) class or other class plasticizers, do not contain harmful additives such as DEHP yet, can not produce secondary pollution, and non-PVC material replaces the PVC material to avoid the adsorptivity of PVC material to medicine to medicinal liquid; 2, simple structure, easy to operate, the mode of mechanical fixation is easy than the mode of original chemical bonding; 3, the outer inclined-plane of inclined-plane and transfusion needle insertion end can prevent leakage and sliding pin effectively with the bibeveled design of gradient in the joint; 4, environmental protection, contaminated soil is buried in the difficult processing of depleted PVC material, burning then can produce hydrogen chloride with bioxin gas, it then is carcinogen that hydrogen chloride can form acid rain ， bioxin, and non-PVC material replaces the PVC material and then can avoid because of handling the pollution that depleted PVC material causes.
