Description
Technical field
The present invention relates to medical instruments field, relate in particular to a kind of bubble detection device.
Background technology
At clinical practice infusion pipeline, to patient, carry out in therapeutic process, must accurately, effectively detect the bubble in infusion pipeline, to guarantee patient's life security.Main flow infusion pump in the market, the bubble detection mode of infusion apparatus product is ultrasound examination mode, in structure, be two sides clamping or help infusion pipeline to guarantee the mode of ultrasonic conducting path, but because existing transfusion device manufacturer is numerous, the transfusion device specification of using, material is different, and cooperation distance between predefined bubble probe is fixed, cannot carry out special coupling according to the difference of pipeline, cause the reliably compacting of transfusion device pipeline, on ultrasonic conducting path, occur that thereby fit clearance produces bubble wrong report and maybe needs to eliminate pipeline fit clearance with extra adjuvant such as vaseline.
Summary of the invention
The object of this invention is to provide a kind of more reliable, be easier to the bubble detection device used, overcome the deficiency of above-mentioned aspect in existing product.
The object of the invention is to be achieved through the following technical solutions:
A kind of bubble detection device, comprise the transmitting terminal and the receiving terminal that are separately positioned on infusion pipeline both sides, described transmitting terminal comprises switching door and transmitting probe, switching door is provided with four projections, projection passes on left screw and is fixed with base plate, base plate middle part is provided with transmitting probe, described transmitting probe left end stretches out base plate, transmitting probe right-hand member is provided with fixture block, fixture block is stuck in transmitting probe in the groove of base plate and four projection formation, transmitting probe is provided with draw-in groove, the diameter of described draw-in groove is 4mm ± 0.2mm, in transmitting probe, be provided with the first piezoelectric chip, the first piezoelectric chip right side is provided with spring, spring is resisted against on switching door, described receiving terminal comprises the receiving transducer corresponding with transmitting probe, is provided with the second piezoelectric chip in receiving transducer, and receiving transducer is separately fixed on mounting bracket and panel.
Beneficial effect of the present invention is:
1, the installation reliability problem of the solution infusion pipeline that most materials are different on the market, size differs in ultrasonic conducting path, makes ultrasonic bubble detection mode more reliable and easy-to-use;
2, the cooperation distance between bubble probe is adjustable, can regulate according to the difference of infusion pipeline, thereby range of application is wider, and make gapless close contact between infusion pipeline and bubble probe, can be because of occurring that gap produces bubble wrong report or need to eliminate the gap between infusion pipeline and bubble probe with adjuvant such as vaseline;
3, draw-in groove plays position-limiting action, thereby prevents that infusion pipeline from producing skew and causing bubble wrong report;
4, spring can be exerted pressure to transmitting probe, thereby prevents that infusion pipeline is because elastic fatigue generation gap is reported by mistake.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the structural representation of the bubble detection device described in the embodiment of the present invention;
Fig. 2 is the left view of the transmitting terminal of Fig. 1.
In figure:
1, transmitting terminal; 101, switching door; 102, transmitting probe; 103, the first piezoelectric chip; 104, projection; 105, screw; 106, base plate; 107, draw-in groove; 108, spring; 2, receiving terminal; 201, receiving transducer; 202, the second piezoelectric chip; 203, mounting bracket; 204, panel; 3, infusion pipeline.
The specific embodiment
As shown in Figure 1-2, a kind of bubble detection device described in the embodiment of the present invention, comprise the transmitting terminal 1 and the receiving terminal 2 that are separately positioned on infusion pipeline 3 both sides, described transmitting terminal 1 comprises switching door 101 and transmitting probe 102, switching door 101 is provided with four projections 104, projection 104 passes on left screw 105 and is fixed with base plate 106, base plate 106 middle parts are provided with transmitting probe 102, described transmitting probe 102 left ends stretch out base plate 106, transmitting probe 102 right-hand members are provided with fixture block, fixture block is stuck in transmitting probe 102 in the groove that base plate 106 and four projections 104 form, transmitting probe 102 is provided with draw-in groove 107, in transmitting probe 102, be provided with the first piezoelectric chip 103, the first piezoelectric chip 103 right sides are provided with spring 108, spring 108 is resisted against on switching door 101, described receiving terminal 2 comprises the receiving transducer corresponding with transmitting probe 201, is provided with the second piezoelectric chip 202 in receiving transducer 201, and receiving transducer 201 is separately fixed on mounting bracket 203 and panel 204.
Bubble detection device described in the embodiment of the present invention designs for domestic general infusion set, and the diameter of infusion pipeline is at 4mm ± 0.2mm, thereby the diameter of draw-in groove 107 is 4mm ± 0.2mm.
During use, infusion pipeline 3 is placed between four projections 104, and be stuck in draw-in groove 107, then receiving transducer 201 is placed on transmitting probe 102 directly over and compress a little infusion pipeline 3, make infusion pipeline 3 very close to each other with the contact surface of transmitting probe 102 and receiving transducer 201.In use procedure, note: the smooth surface of infusion pipeline is without frosted granule or tiny pore; Guarantee the cleaning of the clamping face coordinating with infusion pipeline with transmitting probe 102 and receiving transducer 201, remove in time residual liquor or dirt; While being installed infusion pipeline, need to keep infusion pipeline not stretched and draw, in order to avoid because pipeline is stretched to draw and caused pipeline overall dimensions diminish and cannot guarantee closely cooperating of tube wall and clamping face; In use procedure, pipeline is without continuing to stretch the impact of drawing.
The spring 108 of the bubble detection device described in the embodiment of the present invention makes transmitting probe 102 can regulate the distance of stretching out base plate 106, regulate the strength of compressing infusion pipeline 3, played the effect spacing to infusion pipeline 3, limited again the strength of compressing infusion pipeline 3, alleviated the fatigue of infusion pipeline 3 simultaneously.
The above design of the bubble detection device described in the embodiment of the present invention has guaranteed that infusion pipeline 3 is under the clamping of this product, forming gapless with transmitting probe 102 with receiving transducer 201 contacts, thereby realize the stable and reliable of ultrasound detection, simultaneously because the cooperation of the complete dependency structure design of which and spring 108 realizes, do not need extra auxiliary operation measure and liquor, guaranteed the ease for use on the basis of improving ultrasound detection reliability.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
