Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of infusion set with heating function.
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, set up passage between vein and medicinal liquid common disposable
Medical treatment consumptive materials.Typically by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, dropping funnel,
Bottle plug puncture unit, air inlet pipe, air filter connect composition.Under atmospheric pressure effect, liquid in infusion bottle
Dropping funnel is flowed into along thinner infusion tube, when dropping funnel water column pressure is more than venous pressure, the liquid runs down in bottle
Flexible pipe flows into vein.Sterilization effect duration of medical worker's preoperation inspection disposable transfusion device and being packaged with without gas leakage
And other are abnormal, take out transfusion device, by cone joint partial insertion infusion bottle, hang infusion bottle on transfusion pole,
It is vented to medicinal liquid and flow to tube for transfusion lower end, fasten actuator, then intravenous needle is thrust the vein disinfected, fixing
After Hao, untie tourniquet, adjust flow velocity.
Existing transfusion device there is problems in that first, and time incipient, the medicinal liquid flow velocity in tube for transfusion is very fast,
Along with medicinal liquid flows out, the fluid column in bottle is in a slight decrease, and overhead gas volume slightly becomes big, and pressure slightly reduces so that bottleneck
The total pressure at place is slightly smaller than external atmosphere pressure, and air is just supplemented from air inlet pipe press-in bottle by outer atmospheric pressure, makes
The pressure of bottle mouth position remains essentially in an atmospheric pressure, makes medicinal liquid can the most stably drip, not with bottle
Gradually decreasing of herb liquid changes again. and but when starting, in bottle, the pressure of gas is about an atmospheric pressure, bottle mouth position
Pressure is more than an atmospheric pressure, so always dripping quickly in a period of time started, easily gives patient body
Bring discomfort.Second, when transfusion speed is very fast, the liquid level short time in infusion bottle changes greatly, due to
Air inlet pipe is arranged on bottle plug puncture unit, and the inlet channel of air inlet pipe is very thin, and air just cannot lead to timely
Cross air inlet pipe to enter in infusion bottle and supplement so that during pressure at mouth of infusion bottle change rather than permanent
Fixed, therefore there will be the phenomenon dripped that medicinal liquid cannot be the most stable.
When how to ensure transfusion, no matter transfusion speed is fast, or slowly, what medicinal liquid can be the most stable drips
It is a research the most worth and solves the technical problem that.
Existing transfusion device does not nearly all have heating apparatus, and when cold weather when, transfusion can bring to patient
Some are uncomfortable, and the way usually taked is exactly to put a hot towel or hot water bag on the arm of patient, due to
The time that the cold weather hot towel of employing or hot water bag play heating effect is the shortest.

Embodiment 2: on the basis of embodiment 1, controller uses AT89S51 single-chip microcomputer.
Embodiment 3: on the basis of embodiment 1, the volume of left chamber is 800 milliliters, the volume of right chamber
For 10ml.
The operation principle of the present invention: add medicinal liquid in left chamber, the medicinal liquid in right chamber floods liquid level sensor,
Owing to the volume of right chamber is the least, therefore liquid level will soon maintain an equal level with the liquid level sensor of right chamber, once
Liquid level is less than the height of liquid level sensor, and controller controls intake valve and makes air pass through airway to enter rapidly
Entering in left chamber, bottom left chamber, the pressure at place can increase, and at this moment the liquid in left chamber can be entered by intercommunicating pore
Entering to right chamber, the rightest chamber liquid level maintains an equal level again with liquid level sensor, so the liquid level of right chamber is several
The most invariable, therefore the pressure at infusion hole is invariable, also due to the volume of right chamber is very
Little, therefore start very short time most in transfusion, what medicinal liquid just can be the most stable drips.Lead owing to being specially provided with
Trachea and airway are funnel-form, and therefore air can easily enter in left chamber, though therefore transfusion speed
Quickly, the liquid level of right chamber also is able to keep constant degree.
The using method of the present invention: take off the detachable stopper arranged on liquid filling hole, medicinal liquid is joined left chamber
In, then cover detachable stopper, bottle plug puncture unit is inserted in the rubber closure arranged on infusion hole, the most defeated
Medicinal liquid in liquid flexible pipe can at the uniform velocity drip, and is then changed the speed of transfusion by flow regulator.Needs are heated
As long as time by hand switch close, heating apparatus automatically begins to heat, and heating apparatus is according to the first temperature sensing
Warm temperature can be controlled at a concrete numerical value by the detection of device, and according to the inspection of the first liquid level sensor
Survey, people can be reminded to need to heating apparatus by the first alarm unit and add water.
