Abstract

The utility mode provides a novel infusion device, and relates to the technical field of medical apparatus and instruments. The novel infusion device comprises an infusion flexible tube, a bottle plug puncture device, an air-inlet-tube air filter, a Murphy tube, a flow rate regulator and a vein needle head, wherein a Y-shaped communication tube is installed on one end close to the needle head, a valve is installed at the upper end of the communication tube, the lower end of the communication tube is connected with the needle head into a whole, the side end of the communication tube is a medicine adding tube provided with a spiral protective cap, and a liquid medicine filter is installed inside the communication tube. The novel infusion device has the advantages of facilitating push-injection of medicine and being capable of preventing a connection position of the communication tube and the needle head from falling off.

Description

A kind of novel transfusion device

Technical field

This utility model relates to technical field of medical instruments, is specially a kind of novel transfusion device.

Background technology

At present, transfusion is the treatment means of generally using clinically, in the process of transfusion, according to state of an illness needs, often need the intravenous injection medicine, existing transfusion device generally comprises infusion tube, syringe needle, Murphy tubes etc. are in medicine injection, need to unplug syringe needle and flexible pipe joining place, connect and carry out medicine after the syringe again and inject, have so following defective on the transfusion system structure: after infusion tube and the disconnection of syringe needle place, two-port can be exposed in the air, pollute easily, and linking does not tightly easily enter air, simultaneously, and before docking syringe, also need stuck syringe needle place flexible pipe, in case Hemostatic Oral Liquid refluxes; When other actions of gravity were arranged in transfusion device, syringe needle and flexible pipe joining place disconnected easily, cause syringe needle to come off from transfusion device, thereby affected normal transfusion work.

Summary of the invention

This utility model purpose is exactly a kind of New-type instant medicine injection will be provided and can prevent the transfusion device of syringe needle from coming off communicating pipe.

A kind of novel transfusion device; comprise infusion tube, bottle plug puncture unit, air inlet pipe air filter, Murphy tube, flow regulator, venous needle; nearly needle end is provided with Y shape communicating pipe; be provided with flap valve on communicating pipe; lower end and syringe needle are connected as a single entity; side is that inside is provided with liquid medicine filter with the chemical feed pipe of spiral protective cap.

Than existing transfusion device, directly set up Y shape communicating pipe, can make things convenient for the medicine of directly annotating, effectively avoid the contamination phenomenon of infusing; Liquid medicine filter was set in communicating pipe, the filling medicine is filtered; Communicating pipe, the upper end was provided with flap valve, and the medicinal liquid adverse current enters flexible pipe in the time of can avoiding injecting; Lower end and syringe needle are connected as a single entity, and avoid pressure transfusion or other actions of gravity syringe needle when transfusion device to be connected with communicating pipe and come off, thereby guaranteed stablizing and safety of transfusion.
