It is Fig. 1-4 with reference to figure.A kind of medical infusion stand with transfusion speed stabilization function, comprising: bracket 1 and crossbeam 2, institute It states crossbeam 2 and is set to 1 top of bracket, the crossbeam 2 includes rack 4, rigidity rope 5, gear set 3, and the crossbeam 2 is arranged There is a hollow space, the gear set 3 is set to the hollow space, and the gear set 3 is by completely the same first gear and the Two gears are constituted, and the gear shaft of the 5 connection first gear of rigidity rope, 5 other ends of the rigidity rope connect the rack 4, For the rack 4 for placing infusion bottle, 4 bottom of rack includes two connecting shafts 6, between the connecting shaft 6 between It is consistent away from the infusion pipe diameter used with infusion bottle, 4 bottom of rack, the connecting shaft 6 are connected at the top of the connecting shaft 6 Bottom is connected with transverse slat 7, and the transverse slat 7 is for transfer and places perfusion tube, and the connecting shaft 6 is described for fixing perfusion tube Second gear contact has indentation axis 8, and the indentation axis 8 is set to the hollow space, and 8 lower end of indentation axis is provided with transverse direction Axis 10, for the lateral shaft 10 by passing through among two connecting shafts 6,10 bottom of lateral shaft is provided with arch piece 11, the tooth Trace axis 8 connects motor 9, and the motor 9 is for being lifted the indentation axis 8 and lateral shaft 10.
As a kind of preferred embodiment of the invention, the radius of curvature of the arch piece 11 is consistent with the diameter of perfusion tube.
It further include terminal installation as a kind of preferred embodiment of the invention, the terminal installation is connect with the motor 9, The terminal installation is used to be arranged the rate of climb of the motor 9.
As a kind of preferred embodiment of the invention, the rate of climb of the motor 9 is by standard transfusion speed range computation.
As a kind of preferred embodiment of the invention, the terminal installation is also used to input age and the state of an illness of patient.
It further include processing unit 12 as a kind of preferred embodiment of the invention, the processing unit 12 connects the terminal Device and motor 9, age bracket where the processing unit 12 obtains patient according to the patient age that the terminal installation inputs, The processing unit 12 adjusts standard transfusion speed range according to the age bracket and the state of an illness, and the motor 9 is according to institute State the standard transfusion speed range adjustment rate of climb.
It further include measurement chip 13, alarming device 14 as a kind of preferred embodiment of the invention, the measurement chip 13 connects The processing unit 12 is connect, the alarming device 14 connects the processing unit 12, and the measurement chip 13 is current for measuring Transfusion speed, the processing unit 12 judge the size relation of present infusion speed Yu standard transfusion speed range, when current defeated When liquid speed degree is not fallen within the scope of standard transfusion speed, processing unit 12 controls alarming device 14 and issues warning.
As a kind of preferred embodiment of the invention, the processing chip connects hospital's healthcare system 15, the processing chip It is also used to send medical care request signal to hospital's healthcare system 15.
In the specific implementation process, during patient is infused, the weight of infusion bottle and drug constantly reduces, by In in the initial state, rigidity rope 5 is straightened for infusion bottle and drug, and rigidly restricting when weight constantly reduces 5 starts to withdraw, drive First gear rotation, and first gear rotates counterclockwise.In the setting of original state, second gear is set as revolving counterclockwise Turn, that is, need to set upward sliding for indentation axis 8, i.e., be set as driving up by motor 9, and in the case where corresponding patient It is set as a definite value, under the conditions of customization, the rate of climb of lateral shaft 10 is definite value.When transfusion speed is too fast, the first tooth The real time rotation rate of wheel is greater than the speed of rotation of second gear, accelerates descending first gear to will drive second gear to a certain degree Rotation, since driving rate of the motor 9 to indentation axis 8 is definite value, indentation axis 8 can carry out the second gear for accelerating rotation It adjusts, keeps its rate slack-off, since transmission effect is stronger, the first gear speed of rotation is slack-off.Since 8 climbing speed of indentation axis is The rate of climb of the definite value of standard, the arch piece 11 on lateral shaft 10 is definite value, when transfusion speed is too fast, what infusion bottle rose Rate becomes larger, and 7 climbing speed of transverse slat on rack 4 becomes larger, so that transverse slat 7 is close to arch piece 11 in a dynamic state, to squeeze Perfusion tube, so that flow velocity is slack-off, to adjust flow velocity.In the effect of first gear and second gear, arch piece 11 and transverse slat 7 Under, adjustment to a certain extent is carried out to infusion flow rate.In the case that transfusion speed is slack-off, the weight of infusion bottle and drug reduces Rate is slack-off, and the rate that transverse slat 7 rises is slack-off, and under the action of motor 9, the speed that arch piece 11 rises is definite value, dynamic Under state, for transverse slat 7 far from arch piece 11, perfusion tube is gradually recovered original state, and transfusion speed becomes larger, when arch piece 11 and transverse slat 7 maintain Infusion flow rate reaches stable when dynamic equilibrium.
For the patient of the different age group difference state of an illness, medical staff provides targetedly standard transfusion speed range and defeated Enter to terminal installation, processing unit 12 obtains the standard transfusion speed range in terminal installation and calculates motor according to the above method 9 rate of climb in this case, and the rate of climb is adjusted.
When processing unit 12 judges that present infusion speed is greater than the maximum value of standard transfusion speed range or defeated less than standard When the minimum value of liquid velocity interval, there are emergency situations to the judgement of processing unit 12 in transfusion condition at this time, and processing unit 12 is to warning Device 14 sends control instruction, and alarming device 14 issues phonetic warning, meanwhile, processing unit 12 sends a family to healthcare system 15 The signal of request, calling medical staff come to handle.
The above embodiments merely illustrate the technical concept and features of the present invention, and the purpose is to allow the skill for being familiar with the technical field Art personnel can understand the content of the present invention and implement it accordingly, and can not be limited the scope of the invention with this.All bases Equivalent changes or modifications made by spirit of the invention, should be covered by the protection scope of the present invention.
