Description

Transfusion device

Technical field

This utility model relates generally to a kind of medical supplies.

Background technology

Currently known pair of bifurcated transfusion device device is by tube for transfusion, inserts liquid pin, Murphy's dropper, three flow controllers Switch, transition joint（It is connected with scalp acupuncture）, scalp acupuncture composition.When conditions of patients occurs urgent change, medicine injection is needed Or when changing medicine, typically all filter is separated with scalp acupuncture, bolus injection is carried out, so both easily pollution medicine and transfusions Device inwall, and designed on the market in recent years push away pipeline by medicine and also can only carry out a small amount of bolus injection, without negative pressure, medicine is very Easily overflow outside tube for transfusion, can't play a part of to set up Article 2 liquid-transport pipe-line, when joint link is tighter, be difficult to unclamp Therapeutic time can be caused to be delayed, micro-air easily enters scalp pintle and is difficult to exclude, with intravenous injection and transfusion intravasation, Unnecessary mental pressure is caused to patient and family members.Now with double bifurcated transfusion devices when infusing to patient, pin Head is nowhere placed, and is easily caused pollution.After patient fluids' infused, medical personnel need to extract syringe needle for which, but extract blood vessel Interior syringe needle is arbitrarily exposed to sky with extracting the two stages of sharp instrument of separate after syringe needle, the syringe needle due to having been polluted by blood samples of patients In gas, and syringe needle is played pendulum, and is easily caused medical personnel and is needled wound.

Utility model content

The purpose of this utility model is that providing one kind can overcome known technology shortcoming, is easy to double bifurcated transfusion devices to inject medicine Thing, provides an extra loading passage, the transfusion device for facilitating aseptic syringe needle to place in operating process in emergency situations.

For achieving the above object, scheme of the present utility model is：A kind of transfusion device, by tube for transfusion, inserts liquid pin, and Murphy is dripped Pipe, multiple flow control switch, filter connector, scalp acupuncture are constituted, and which is particular in that above the filter of transfusion device A bypass pipe is connected to by a tee T in a small distance, being provided with the triangle connection sheet of the double bifurcateds of transfusion device can The hole of insertion needle.

Using such scheme, one group of venous line is set up by bypass pipe in infusion process, efficiency is improve, in vein Before puncture, aseptic syringe needle can be put in aseptic position, reduce the pollution rate of syringe needle, nurse inserts the needle into hole in operation Interior, it is to avoid contaminated pinhead is hindered by syringe needle, it is achieved that the purpose of this utility model.

This programme is described in more detail with reference to diagram and embodiment.

Specific embodiment

As shown in figure 1, described transfusion device accesses two first flow controlling switches 3- by medicated bag 1 is store through tube for transfusion 2-1 1,3-2 forms double bifurcated transfusions, and two paths merge in the crotch of trigonum 4 pairs through tube for transfusion 2-2, and described trigonum 4 is One thin slice, has relatively thin thickness, such as 2mm, and two breeches pipes are linked together, and is provided with hole in trigonum 4, hole be circular port 5 or Square hole, two breeches pipes enter Mo Feishi droppers 6 by pipeline 2-3 after merging, then by pipeline 2-4 and a second flow Controller 7 connects, then is connected with a bypass pipe 8 by pipeline 2-5, and described bypass pipe is by a tee T 9 and transfusion Pipe 2-7 is connected, and the arm of tee T connects a short transfusion cylinder 11 with calparine cap 10, and bypass pipe 8 down connects a filtration Device 12, connects an injection needle 13 through filter connector pipeline 2-6 out.

The calparine cap 10 of described bypass pipe 8 is connected with short transfusion cylinder 11 by screw thread, generally, by liver Medicine injection after plain cap sterilization, is plastic due to above-mentioned, and acupuncture is easy to, and in case of emergency, can unload heparin Cap carries out heavy dose of bolus injection.When the two or more medicines of patient alternately need to be input into, another group is connected on this by-pass line Tube for transfusion, on the premise of opening two groups of venous accesses, sets up one group of tube for transfusion.

5 nurse of circular port for opening of trigonum can conveniently insert syringe needle, without the need for placing syringe needle when busy, to shield Scholar's operation brings conveniently.
