Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of from heating transfusion device.
Background technology
Medical infusion bottle be for patient infusion fashionable dress the bottle of the liquid of medical configuration in defeated human body.Transfusion device be for venous transfusion through aseptic process, the common disposable medical treatment consumptive materials of setting up passage between vein and medicinal liquid.Generally connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, dropping funnel, bottle plug puncture unit, air inlet pipe, air filter.Under atmospheric pressure effect, the infusion tube that in infusion bottle, liquid runs down is thinner flows into dropping funnel, and when dropping funnel water column pressure is greater than venous pressure, the liquid runs down flexible pipe in bottle flows into vein.The sterilization effect duration of medical worker's preoperation inspection disposable transfusion device and packaging are with or without gas leakage and other exceptions, take out transfusion device, by cone joint partial insertion infusion bottle, hang infusion bottle on transfusion pole, be vented to medicinal liquid and flow to tube for transfusion lower end, fasten actuator, again intravenous needle is thrust the vein disinfected, after fixing, untie tourniquet, adjustment flow velocity.
There is following problem in existing transfusion device: first, medicinal liquid flow velocity time incipient in tube for transfusion is very fast, along with medicinal liquid flows out, fluid column in bottle is in a slight decrease, overhead gas volume slightly becomes large, pressure slightly reduces, the total pressure of bottle mouth position is made to be slightly smaller than external atmosphere pressure, air just supplements by outer atmospheric pressure from air inlet pipe press-in bottle, the pressure of bottle mouth position is made to remain essentially in an atmospheric pressure, medicinal liquid can at the uniform velocity stably be dripped, minimizing gradually not with bottle herb liquid changes again. and but when starting in bottle the pressure of gas be approximately an atmospheric pressure, the pressure of bottle mouth position is greater than an atmospheric pressure, so always drip very fast in a period of time started, easily bring discomfort to patient body.Second, when transfusion speed is very fast, the liquid level short time in infusion bottle changes greatly, because air inlet pipe is arranged on bottle plug puncture unit, the inlet channel of air inlet pipe is very thin, air just cannot be entered in infusion bottle by air inlet pipe timely and supplement, thus makes that change during the pressure at mouth of infusion bottle place instead of constant, therefore there will be the phenomenon of dripping that medicinal liquid cannot be at the uniform velocity stable.
When how to ensure transfusion, no matter transfusion speed is fast, or slowly, and medicinal liquid can both at the uniform velocity stable dripping be the technical problem of a very worth research and solution.
Existing transfusion device does not nearly all have heating apparatus, when cold weather time, transfusion can be with to patient and be served discomfort, the way usually taked is exactly on the arm of patient, put a hot towel or hot water bag, and due to cold weather, to adopt hot towel or hot water bag to play time of heating effect very short.
Summary of the invention
The technical problem to be solved in the present invention: existing transfusion device is within a period of time started, and medicinal liquid always drips very fast, cannot at the uniform velocity stable dripping, and easily brings discomfort to patient body; And when transfusion speed is very fast, also easily there is the phenomenon of dripping that medicinal liquid cannot be at the uniform velocity stable.
