Abstract
The utility model belongs to the technical field of medical instruments. Disposable transfusion systems which are widely used at present is difficult in controlling about flow quantity accurately. The utility model provides a new style flow regulator. The bottom surfaces of grooves of traditional flow regulators are intercepted with an inclined comminution type groove, which makes the passing areas of liquid flow quantity correspondingly more concentrate. When the utility model is used, the flow quantity can be more accurately controlled, and treatment requirements of various patients can be fulfilled. Additionally, the opened pipe clamping grooves are extended from one end of original flow regulators by the utility model, facilitating transfusion pipes directly embedded into the grooves by medical care personnel when the transfusion needs to be urgently stopped.
Description
This utility model belongs to medical instruments field, is specifically related to the flow regulator that uses on the disposable infusion syringe.
The present disposable transfusion device that uses in the hospital, flow-control is difficult to accurately, or flow is excessive, or it is closed in smaller in Flow-rate adjustment, is difficult to the degree that reaches satisfied.If flow was excessive when patient used, patient's heart burden, patient can not accept, and if patient when using flow too little, then can make the transfusion time lengthening, increase patient's burden.Also have, when infusing, often need use quick locking chuck as suspending under certain conditions, to open again after perhaps closing flow regulator, want to be transferred to original flow velocity so and extremely take the time, medical personnel influence the raising of quality of medical care using, rescue sense inconvenience often like this.
The purpose of this utility model is the deficiency that overcomes flow regulator in the existing transfusion device, and a kind of novel multifunctional flow regulator is provided, and makes patient use safer and more comfortable, and medical personnel use more aspect.
The purpose of this utility model is achieved in that this novel multifunctional flow regulator improves traditional flow regulator.The bottom surface of its Flow-rate adjustment groove in flow regulator intercepts an oblique decrescence formula groove, the area that fluid flow is passed through is more concentrated relatively, flow when flow regulator goes to zero diminishes, the flow velocity gradual slow reduces, until complete closed, like this, just can control flow more exactly in use, satisfy various patients' treatment needs.In addition, this utility model flow regulator also extends the conduit clamping slot of an opening at an end of original flow regulator, be convenient to medical personnel when needs are closed flow regulator getting final product in the direct embedded groove of transfusion catheter.Like this, medical personnel just can omit original locking chuck in use, and are more convenient to use.
The multi-functional flow regulator flow that this utility model provides is owing to increased the decrescence groove of formula in the bottom of Flow-rate adjustment groove, and the scope of flow-control has increased, and particularly than Small Flow Control the time, patient uses safety and comfort more.In addition, extend the conduit clamping slot of an opening, like this, not only reduced manufacturing cost, and make medical personnel more convenient when urgent the rescue at an end of flow regulator.
Below in conjunction with accompanying drawing and use principle this utility model is described further.

The left view of the multi-functional flow regulator that Fig. 2 provides for this utility model
Fig. 3 is the vertical section rearview of multi-functional flow regulator shown in Figure 1
The vertical view of the multi-functional flow regulator that Fig. 4 provides for this utility model
The multi-functional flow regulator that this utility model provides is made up of housing 1, Flow-rate adjustment groove 2, pulley regulating tank 3, conduit clamping slot 4, flow arrow 5, pulley 6.Wherein, there is the groove of an oblique decrescence formula bottom surface of Flow-rate adjustment groove 2 in the housing 1, pulley 6 is arranged in the pulley regulating tank, can regulate the size of infusion flow, one flow arrow 5 is arranged in the outside of housing 1, can accurately indicate the direction of flow size, extend the conduit clamping slot 4 of an opening at an end of housing 1, can be stopping transfusion in the direct embedded groove of transfusion catheter.In use, but the pulley 6 in the regulated at will pulley regulating tank 3, when direction according to flow arrow 5, when pulley 6 is pushed to the direction of arrow indication, the oblique decrescence direction motion of groove in Flow-rate adjustment groove 2 of this pulley 6 compressing transfusion catheters, then the flow of infusing in the transfusion catheter reduces gradually, stops until required flow.In addition, in the time of in infusion process, need promptly stopping to infuse, only need transfusion catheter is directly embedded in the conduit clamping slot 4 and can realize.
The multi-functional flow regulator that this utility model provides, it is more accurate to the control of flow to make when transfusion, particularly under the less situation of flow, so just improved quality of medical care greatly to patient, make patient's safety and comfort more, it is convenient that increase conduit clamping slot uses medical personnel.
