Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of intravenous injection medication infusion device.
Background technology
General, during conventional disposable transfusion device intravenous injection medicine, transfusion device can only be connected punishment with scalp acupuncture
From, again syringe is accessed scalp acupuncture after separation, both added the chance of pollution, the most inevitably make air bubble enter head
Sword-shaped needle, is pushed into patient's blood vessel, adds again primary pollution and enters the chance of air, also add after having separated medicine injection
The workload of nurse.And, the length between filter and the scalp acupuncture of traditional transfusion device is mostly 15 cm, transfusion
Device and scalp acupuncture junction are within these 15 centimetres, and the quiet medicine pushed away can also not filtered by the filter of upstream, some microgranule quilt
It is injected into internal, infusion reaction may be caused.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, it is provided that a kind of intravenous injection medication infusion device.
The technical solution of the utility model realizes in the following manner, this intravenous injection medication infusion device, its structure bag
Include tube for transfusion and intravenous injection needle,
The downstream of tube for transfusion is provided with intravenous injection needle,
It is provided with filter for transfusion on the pipe shaft of the tube for transfusion of upstream 5～6 centimeters of intravenous injection needle；
It is provided with three-way cock on the tube for transfusion of filter for transfusion upstream；
Be provided with forthright pipe portion and bypass duct portion on three-way cock, bypass duct portion be perpendicular to forthright pipe portion and with forthright pipe portion
Pass through connection mutually；
The forthright pipe portion at the place of passing through is provided with valve body mutually, is provided with three-way valve spool in valve body；
Three-way valve spool is provided with forthright passage and bypass passage；Bypass passage is arranged on the side of forthright passage, branch road
Passage and forthright passage are perpendicular through；
The forthright passage of three-way valve spool and the forthright pipe portion of three-way cock are coaxially set；
The bypass passage of three-way valve spool and the bypass duct portion of three-way cock are coaxially set；
Three-way valve spool connects valve handle, and valve handle rotates and drives three-way valve spool to rotate switching valve path in valve body；
The bypass duct portion of three-way cock connects intravenous injection branch road syringe, and intravenous injection branch road syringe is provided with
Branch pipe joint；Bypass duct block it is provided with on branch pipe joint.
Bypass duct block is threaded connection with branch pipe joint periphery.
It is provided with transfusion on the tube for transfusion of three-way cock upstream and drips kettle.
The upstream extremity of tube for transfusion is provided with feed liquor syringe needle.
This utility model compared with prior art produced by provide the benefit that:
This intravenous injection medication infusion device inserts intravenous injection branch road syringe at the Upstream section of filter for transfusion, the most quiet
The medicine of arteries and veins instillation and intravenous injection can carry out the filtration of medicinal liquid eventually through filter for transfusion, goes the removal of impurity, is effectively ensured
The safety of medicinal liquid.
Before intravenous injection medicine, first three-way cock is switched to forthright pipe portion, upstream and the state of bypass duct portion path, by upper
Trip medicinal liquid to the filling of bypass duct portion and overflows at branch pipe joint, it is therefore an objective to aerofluxus, after bypass duct portion is full of medicinal liquid, by three
Open up pass and switch to bypass duct portion and the state of forthright pipe portion, downstream path, at branch pipe joint, connect normal saline or Fructus Vitis viniferae
Injection is quiet pushes away syringe for sugar, injects in advance, it is therefore an objective in the medicinal liquid in tube for transfusion is advanced venous patient in advance, with life
Reason saline or glucose injection washing pipe, in order to avoid the most quiet medicine pushed away and previous medicine have chemical reaction；After washing pipe, then access
Quiet injecting emitter, carry out pushing away patient is quiet, now upstream transfusion is closed under the effect of three-way cock, does not interferes with quiet pushing away；Quiet
Postponing can washing pipe, the transfusion state that then switching three-way switch is the most original, recovery transfusion again.
Without separating head sword-shaped needle, and medicine can also filter through medicine filter, reduces drug contamination and enters with air
Enter.Even and if patient uses disposable aspiration needle to puncture, it is possible to avoid again puncturing, to cause the misery that patient is bigger.
A bypass duct block is put into, it is possible to keep nose end hygiene at branch pipe joint end.
This intravenous injection medication infusion device is reasonable in design, simple in construction, safe and reliable, easy to use, be easily maintained, have
Well popularizing value.
