The specific embodiment
The utility model discloses the flow regulator that a kind of fluid flow can precision control.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out to clear, complete description, obviously, described embodiment is only this utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.
The purpose of this utility model is to solve the problems of the technologies described above, and proposing one can support the use with existing transfusion device, and can realize the device of accurate Flow-rate adjustment, to meet clinical actual demand, realizes the accurate flow-control of transfusion and blood transfusion.
This utility model is achieved through the following technical solutions.
The flow regulator that this utility model provides is by two parts, and pedestal 1 and swing handle 2 form (seeing Fig. 1, Fig. 2), and described pedestal 1 comprises inlet 3 and liquid outlet 4, connects respectively transfusion catheter, forms complete transfusion stream.
Be specially, as shown in Figure 1, Figure 2, shown in Fig. 4, Fig. 9 and Figure 14, the accurate flow regulator of a kind of medical dial type, comprise, pedestal 1 and be arranged on the swing handle 2 on described pedestal 1, described pedestal 1 comprises perpendicular to horizontal plane direction, the cylindrical cavity 14 of an end opening, and described swing handle 2 is installed in described cavity 14;
Described swing handle comprises swing handle matrix 21,
Knob 22, is arranged at described swing handle matrix 21 upper surfaces;
Runner 23 comprises sprue 233 and secondary fluid course, is arranged at described swing handle matrix 21 inside, and the length direction of sprue is identical with the length direction of described knob; Its residing transversal circle is divided into two semicircles by described sprue;
For the first time runner 231 and for the second time runner 232 be arranged at described sprue entrance and exit along the circumferencial direction of the transversal circle of described swing handle matrix respectively, and described runner for the first time and described runner for the second time lay respectively at different semicircles;
Described pedestal comprises inlet 3 and liquid outlet 4, respectively the entrance and exit of corresponding described swing handle sprue; Described runner for the first time and described runner for the second time all can be communicated with the inlet of described corresponding pedestal and liquid outlet; Described flow channel depth is for the first time deepened to end gradually by top, and end is connected with the entrance of described sprue.Preferably, described pedestal also includes indicating graduation 11 and is arranged at the upper surface of described pedestal.Preferably, described pedestal also comprises stops payment piece 13, is arranged at the upper surface of described pedestal and matches with described knob.In the time that knob rotates to ON, first stops payment piece can prevent excessive left-handed of knob, and in the time that knob rotates to OFF, second stops payment the dextrorotation that piece can prevent that knob is excessive, plays the effect of buffering rotation, prevents the damage of swing handle.Preferably, described pedestal also comprises that anti-slip tank 15 is arranged at the sidewall outside of described pedestal, as shown in Figure 6.Preferably, one end of described knob is provided with pointer 24 as shown in figure 12.Preferably, described swing handle is embedded in the cavity of described matrix.
According to this utility model, on described pedestal upper surface and dial plate, also comprise direction of rotation mark 12, described knob is rotated according to the direction shown in described direction of rotation mark 12, from ON to OFF.
According to this utility model, because the degree of depth of described runner is for the first time deepened gradually from top to end, so by rotating swing handle, can change runner size, play flow is carried out to precision control, meet the accurate input quantity of medicinal liquid.When turning handle, stream size is linear change, and therefore its flow can, slowly with the rotation linear change of handle, can not produce the phenomenon that medicinal liquid flow is uprushed yet.The flow regulator that this utility model provides is adapted at ICU intensive care unit(ICU), operating room, emergency room, anesthesia class, and needs the place of various accurate transfusions to use.Rotate by swing handle, regulate pointer to identify flow by corresponding dial plate right side scale, carry out more intuitively Flow-rate adjustment.
The flow regulator that this utility model provides is by direct swing handle and pedestal being carried out to chimeric use, forming airtight continuous stream.Wherein swing handle, there is the flow path groove of a change in depth its side, by rotating swing handle, can realize the change of runner size, thereby realizes medicinal liquid flow and the accurate control of flow velocity.The direction of arrow shown in Figure 18 is the flow direction of liquid in flow regulator, and Figure 18 should be with the runner shown in Figure 14 two parts that hand-type overlaps, because the profile that Figure 14 is Figure 13, be upper section and Figure 14 shows, and the runner of showing in Figure 18 actual should be the lower section of Figure 13.
Can find out by the variation shown in Figure 15 ~ Figure 17 and Figure 18, carry out Flow-rate adjustment by rotary handle, between ON shelves → OFF shelves, by the continuous variation of the flow path groove degree of depth, realize the even variation of stream size, thereby guarantee the accurate control to flow.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use this utility model.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, this utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
