Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1 air inlet syringe needle, 2 air inlet pipe, 3 bottle plug puncture units, 4 balanced valves, 5 second liquid medicine filters, 6 kettles, 7 infusion tubes, 8 flow regulators, 9 first liquid medicine filters, 10 intravenous needles, 11 helmets.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model will be further described:
As shown in Figure 1.A kind of medical Transfusion device, comprise infusion tube 7, the top of infusion tube 7 is provided with air inlet pipe 2 and bottle plug puncture unit 3, the middle part of infusion tube 7 is provided with drips kettle 6 and flow regulator 8, the bottom of infusion tube 7 is connected with intravenous needle 10, intravenous needle 10 is provided with helmet 11, the first liquid medicine filter 9 is provided with between infusion tube 7 and intravenous needle 10, air inlet pipe 2 is provided with air filter, also comprise a balanced valve 4, balanced valve 4 is provided with an air inlet syringe needle 1, air inlet syringe needle 1 is connected with air inlet pipe 2 by balanced valve 4, bottle plug puncture unit 3 is connected with infusion tube 7 by balanced valve 4.
Described balanced valve 4 comprises vapour lock control valve and infusion pump, and vapour lock control valve is communicated with air inlet syringe needle 1 and air inlet pipe 2, and vapour lock control valve is a knob valve; Infusion pump is communicated with infusion tube 7 and bottle plug puncture unit 3.When medicinal liquid pressure of the inside of a bottle increases or reduce, medicine liquid-dripping is affected, and vapour lock control valve is mainly in order to regulate and balance set by pressure of the inside of a bottle.Vapour lock control valve installation site communicates with air inlet pipe, can control the open and close of air inlet pipe 2 passage by rotating valve and regulate the size of communication port.Infusion pump can accurately control number of infusion drops or infusion flow rate, ensure medicine can speed even, accurately and enter in patient body safely and play a role, transfusion speed is not affected by human body back pressure and operator, and infusion is accurately and reliably for dose.
Be separately installed with pressure transducer at described air inlet syringe needle 1 and bottle plug puncture unit 3 place, pressure transducer is connected with the alarm be arranged on balanced valve 4.Alarm can adopt now conventional audible-visual annunciator, when occurring in medicinal liquid bottle that bubble, air inlet pipe occur that obstruction or medicinal liquid are totally lost, can exception be there is in medicinal liquid bottle bottom pressure, Signal transmissions can be caused alarm equipment alarm to alarm when sensing pressure anomaly by pressure transducer, causes the attention of nursing staff in time and carries out respective handling.
The length of described air inlet syringe needle 1 is greater than the length of bottle plug puncture unit 3.Air inlet syringe needle 1 also can arrange multiple different specification according to service condition difference, preferably longer air inlet syringe needle 1 can prevent the admission pressure in medicinal liquid bottle not enough, greatly reduce the situation that bubble appears in the class medicines such as albumen, decrease the wasting phenomenon that medicinal liquid bubble causes.
Described infusion tube 7 is provided with the second liquid medicine filter with the junction of balanced valve 4.
For ease of to understanding of the present utility model, below in conjunction with a use procedure, the utility model will be further described:
During use, the sterilization effect duration of medical worker's preoperation inspection transfusion device and packaging are with or without gas leakage and other exceptions, take out transfusion device, air inlet syringe needle 1 and bottle plug puncture unit 3 are inserted medicinal liquid bottle, hang medicinal liquid bottle on drip stand, be vented to medicinal liquid and flow to infusion tube 7 lower end, fasten flow regulator 8, again intravenous needle 10 is thrust the vein disinfected, after fixing, untie tourniquet, by the vapour lock control valve on balanced valve 4 and infusion pump, admission pressure and medicine liquid-dripping speed are adjusted to correct position.
Now, under atmospheric pressure effect, the infusion tube 7 that in bottle, liquid runs down is thinner flows into and drips kettle 6, and when dripping kettle 6 water column pressure and being greater than venous pressure, the liquid runs down infusion tube 7 in bottle flows into venous patient.Now longer air inlet syringe needle 1 can prevent the admission pressure in medicinal liquid bottle not enough, makes the class medicines such as albumen occur bubble; The infusion pump of balanced valve 4 can accurately control number of infusion drops or infusion flow rate, ensure medicine can speed even, dose accurately and enter in patient body safely and play a role, transfusion speed is not affected by human body back pressure and operator, infusion accurately and reliably, play the effect of double insurance, can contribute to reducing clinical nursing activity intensity, improve the accuracy of infusion, safety and nursing quality.
This utility model structure is simple, use, make safe ready, can according to the difference of pharmaceutical properties, patient's body constitution, different speed of intravenous infusion is precisely set, avoid occurring that transfusion is too fast, cross the problem being all difficult to the therapeutic effect reaching expection slowly, substantially increase nursing safety, decrease the wasting phenomenon that medicinal liquid bubble causes.
In this utility model, " top ", " bottom " etc. be all for convenience of description and adopt relative position, can not be interpreted as absolute position form to restriction of the present utility model.
The foregoing is only preferred embodiment of the present utility model; it is not whole embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
