Further, opposite side relative with elastica in the drain mechanism is provided with rib, and the edge of rib is provided with flange; Holder is provided with the adaptive draw-in groove of flange of rib.
Further again, the wall that is arranged in a side of draw-in groove on the holder is provided with briquetting, and the middle part of briquetting is connected with the holder pivot by the pivot that embeds in the holder wall, and the lower side of briquetting and the bottom of holder flexibly connect by back-moving spring; The upper end of briquetting is provided with barb.
Further, the outer wall of the rib of drain mechanism is provided with the groove adaptive with the barb of briquetting, and the below of groove is provided with the wedge-shaped slot adaptive with the width of briquetting.
Fixture provided by the utility model, syringe can be prolonged pipe by drain mechanism couples together, and the holder by being used for fixing drain mechanism can be fixed on the syringe pump shell prolonging pipe, reduced because the risk that pipeline may cause when unfettered, active fixture block makes fixing operation be more convenient for realizing; In addition, the pressure that can dynamically detect in the pipeline by this device changes, and in time reports to the police when blocking generation, has greatly improved the safety in the syringe pump use.
Description of drawings
Fig. 1 is the split structural representation that a kind of syringe that detects dynamic pressure provided by the utility model prolongs pipe fixing device;
Fig. 2 is the cutaway view that a kind of syringe that detects dynamic pressure provided by the utility model prolongs pipe fixing device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described.
A kind of syringe that detects dynamic pressure provided by the utility model prolongs pipe fixing device and is located on the syringe pump of clamping syringe, as shown in Figure 1, this fixture comprises the holder that links to each other with the syringe pump shell 1 and is located at pressure detecting mechanism 3 on the holder 1, is provided with pressure transducer in the pressure detecting mechanism 3; Also be provided with on the holder 1 with syringe and prolong the drain mechanism 2 that the pipe one is connected, one side of drain mechanism 2 is provided with elastica 2-1, be provided with the flow-guiding channel 2-4(that communicates with syringe prolongation pipe 7 and seal in the drain mechanism 2 and see Fig. 2 by elastica 2-1), elastica 2-1 contacts with the pressure transducer of pressure detecting mechanism 3.
Elastica 2-1 can be made by elastomeric PVC material, makes it can respond to the small variations of fluid pressure among the flow-guiding channel 2-4.
For making drain mechanism 2 can be fixed in the holder 1 safely, be respectively equipped with the structure that cooperatively interacts on drain mechanism 2 and the holder 1, for example, opposite side relative with elastica 2-1 in drain mechanism 2 is provided with rib 2-2, the edge of rib 2-2 is provided with flange, and holder 1 is provided with the draw-in groove 1-1 adaptive with the flange of rib 2-2; Similarly, also be provided with the groove adaptive on the holder 1, so that whole drain mechanism 2 is positioned in the holder 1 reposefully with drain mechanism 2.
More preferably, the side of draw-in groove 1-1 is provided with the briquetting 4 that is used for further fixedly drain mechanism 2 on the holder 1, briquetting 4 is located at the wall of a side that is arranged in draw-in groove 1-1 on the holder 1, the middle part of briquetting 4 is connected with holder 1 pivot by the pivot 5 that is embedded in holder 1 wall, and the bottom of the lower side of briquetting 4 and holder 1 flexibly connects by back-moving spring 6; In addition, the upper end of briquetting 4 is provided with barb, and the outer wall of the rib 2-2 of drain mechanism 2 is provided with the groove 2-3 adaptive with the barb of briquetting 4.Adopt this structure, briquetting 4 can be open and can reset under the effect of back-moving spring 6, is convenient to realize the fixing of drain mechanism 2 and removes operation.
