Embodiment one:
It is Fig. 1-4 with reference to figure.A kind of medical infusion stand with stable transfusion speed function, comprising: bracket 1, crossbeam 2, it is described Crossbeam 2 is set to 1 top of bracket, and the crossbeam 2 includes rack 3 and elastic string 4, the 2 middle part hollow out of crossbeam, institute It states hollow part and is provided with gear set 5, the gear set 5 is made of first gear and second gear, and the first gear size is remote Less than the second gear, the first gear is engaged with the second gear, described in the gear axis connection of the first gear 4 one end of elastic string, 4 other end of elastic string connect the rack 3, and the rack 3 is described to put for placing infusion bottle Setting 3 bottom of frame includes two connecting shafts 6, and the spacing between the connecting shaft 6 is consistent with the infusion pipe diameter that infusion bottle uses, institute It states and connects 3 bottom of rack at the top of connecting shaft 6,6 bottom of connecting shaft is connected with transverse slat 7, and the transverse slat 7 is used for transfer And perfusion tube is placed, the connecting shaft 6 is arranged for fixing perfusion tube, the hollow-out part close to the side wall of the second gear There is limiting slot, indentation axis 8 is provided in the limiting slot, the indentation axis 8 is engaged with second gear, 8 lower end of indentation axis It is provided with horizontal axis 9, the horizontal axis 9 extends among the connecting shaft 6, and the horizontal axis 9 is provided with hydraulic axis 10, the hydraulic axis 10 bottom ends are provided with arch piece 11, and the second gear is used for the rotation of the equivalent first gear, and the hydraulic axis 10 is used for Perfusion tube is limited using the arch piece 11 and the transverse slat 7 according to the rotation of the second gear.
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.
As a kind of preferred embodiment of the invention, the hydraulic axis 10 is set to the cross above the transverse slat 7 9 lower surface of axis.
As a kind of preferred embodiment of the invention, the horizontal axis 9 is connect with the indentation axis 8 by lifting device 12, institute It states lifting device 12 and adjusts initial flow rate by adjusting the distance between the horizontal axis 9 and described transverse slat 7.
As a kind of preferred embodiment of the invention, the lifting device 12 is connected with terminal installation 13, the terminal installation 13 for inputting age and the state of an illness of patient.
It further include processing unit 14 as a kind of preferred embodiment of the invention, the processing unit 14 connects the terminal Device 13 and lifting device 12, the processing unit 14 obtain patient institute according to the patient age that the terminal installation 13 inputs In age bracket, the processing unit 14 adjusts standard transfusion speed range, the liter according to the age bracket and the state of an illness Falling unit 12 adjusts the rate of climb according to the standard transfusion speed range.
It further include measurement chip 15, alarming device 16 as a kind of preferred embodiment of the invention, the measurement chip 15 connects The processing unit 14 is connect, the alarming device 16 connects the processing unit 14, and the measurement chip 15 is current for measuring Transfusion speed, the processing unit 14 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 14 controls alarming device 16 and issues warning.
As a kind of preferred embodiment of the invention, the processing chip connects hospital's healthcare system 17, the processing chip It is also used to send medical care request signal to hospital's healthcare system 17.
In the specific implementation process, during patient is infused, the weight of infusion bottle and medical fluid constantly reduces, Under certain reduction speed, the speed that elastic string 4 shrinks the pulled rising of rack 3 is certain, and first gear rotation Rate is also certain, and second gear is driven by first gear to which the rate rotated is also certain, at this time due to the biography of second gear Dynamic, the rate of 8 upward sliding of indentation axis is also certain value.First gear is pinion gear, and pinion mate changes in infusion rate to be had There is obvious embodiment, such as infusion rate increases, the rate that rack 3 rises increases, and the rate of first gear rotation changes It is more obvious, therefore when there is the slight change of rate, first gear can more accurate generation react accordingly, In the transmission process of first gear and second gear, since second gear size is greater than first gear, since infusion flow rate increases Caused by first gear slewing rate increase, i.e., first gear angular speed increase, under the conversion of second gear, the second tooth The angle for taking turns rotation is smaller than first gear, so that the rate that indentation axis 8 rises is consistent with the first gear speed of rotation, and Rate change and to can be accurately driven in the biggish situation of first gear Effect of Rotation.Under the action of inertia, hydraulic stem It is maintained at length and hydraulic degree under original rate, when rate increases, the rate that transverse slat 7 rises increases, and in the work of inertia The rate change risen with lower arch piece 11 has a hysteresis quality, therefore under the action of hydraulic axis 10, arch piece 11 and transverse slat 7 Transverse slat 7 is shown as in a dynamic state close to arch piece 11, so that perfusion tube is squeezed, so that infusion flow rate is reduced, until infusion Flow velocity returns to original state.
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 13, processing unit 14 obtains the standard transfusion speed scope control lifting device 12 in terminal installation 13 and rises Or decline, so that the interval between arch piece 11 and transverse slat 7 is in arch piece corresponding to corresponding standard transfusion speed range At spacing distance between 11 and transverse slat 7.
When processing unit 14 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 14 in transfusion condition at this time, and processing unit 14 is to warning Device 16 sends control instruction, and alarming device 16 issues phonetic warning, meanwhile, processing unit 14 sends a family to healthcare system 17 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.
