Abstract
The utility model discloses a flow control device for a transfusion device. The flow control device comprises a housing and a transfusion tube passing through the housing; a pressing roll is arranged inside the housing; a plurality of protrusions, from high to low, are arranged on the outer peripheral edge of the pressing roll in an orderly fashion; and the protrusions are pressed onto the transfusion tube. The utility model has a simple structure, and ensures the stability and the reliability of transfusion. Moreover, the utility model can ensure that the transfusion flow is determined based on a scale and kept unchanged.
Description
Technical field
This utility model relates to a kind of device of fluid flow in the transfusion device being regulated when carrying out venous transfusion in curative activity.
Background technology
Venous transfusion is a kind of the most used treatment method in present curative activity.And when carrying out venous transfusion, all must use disposable transfusion device.The application of disposable transfusion device in curative activity can be avoided the cross infection, the pathophoresis that cause because of using repeatedly of transfusion device between the patient, can avoid cleaning the unexpected injury that thorough residue causes other patients because of tube for transfusion.Theory and practice proves that all the disposable use of transfusion device is necessary, and this also is a undisputable fact to have expended great deal of raw materials because of the disposable use of transfusion device.In addition, because the general infusion set degree of regulation is inaccurate, also can make troubles to the patient.
The utility model content
This utility model has solved the weak point of above-mentioned prior art existence and a kind of adjusting device that can accurately control the transfusion device flow is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of transfusion device flow regulator, comprise shell, pass the tube for transfusion of enclosure, be provided with pressure roller in the described housing, the periphery of this pressure roller is along being provided with the orderly a plurality of projectioies of height, and this projection is by being pressed on the described tube for transfusion.
According to another embodiment of the present utility model, the transfusion device flow regulator comprises that further described pressure roller is provided with regulating handle, with offer spacing hole on the shell of regulating handle corresponding position, described regulating handle can move in described spacing hole and locate.
According to another embodiment of the present utility model, the transfusion device flow regulator comprises that further described pressure roller and described shell are rotatably connected by rotating shaft, and rotating shaft is fixed on the housing.
According to another embodiment of the present utility model, the transfusion device flow regulator comprises that further the case surface at described spacing hole place is provided with scale.
The beneficial effects of the utility model are, this utility model is simple in structure, and are easy to operate, guarantee that transfusion is stable and reliable, and can make the big or small constant of transfusion device flow by scale.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
1. shells among the figure, 2. tube for transfusion, 3. pressure roller, 4. projection, 5. regulating handle, 6. spacing hole, 7. rotating shaft.
The specific embodiment
With preferred embodiment this utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the sketch map of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the structure relevant with this utility model.
Transfusion device flow regulator shown in Fig. 1-2, comprise shell 1, pass the tube for transfusion 2 of shell 1 inside, be provided with pressure roller 3 in the described housing 1, the periphery of this pressure roller 3 is along being provided with four orderly projectioies 4 of height, and this projection 4 is by being pressed on the described tube for transfusion 2.This utility model is preferentially selected 4 projectioies 4 that height is orderly for use, wherein, above-mentioned protruding 4, the flow grade of restriction tube for transfusion 2 be respectively 5-10 drip/minute, 10-20 drips/minute, 20-40 drips/minute, 40-60 drips/minute, also have the projection of being exactly 4 not to be pressed on the tube for transfusion 2, be and often open grade.
In addition, for making the user easy to adjust, pressure roller 3 is provided with regulating handle 5, and offers spacing hole 6 on the shell 1 of regulating handle 5 corresponding positions, described regulating handle 5 can move in described spacing hole 6 and locate, and pressure roller 3 is rotatably connected by rotating shaft 7 with described shell 1.Shell 1 surface at spacing hole 6 places is provided with scale, is used to show above-mentioned flow grade.When the user uses, as long as regulating handle 5 is allocated to respective level by demand.
Should be appreciated that foregoing description only is in order to set forth this utility model.Those skilled in the art can make multiple replacement form and modification not breaking away under the situation of the present utility model.Therefore, this utility model is intended to all these replacement forms, modification and modification and is included in the protection domain of appended claims.
