Description
Technical field
This utility model belongs to medical apparatus technical field, particularly relates to a kind of remote contrast agent bolus device.
Background technology
Some x-ray visualization requires bolus administration of contrast agent under fluoroscopic monitoring and selects the best opportunity to photograph, but, easily operator is damaged under being closely exposed to x-ray for a long time.
Summary of the invention
The purpose of this utility model is to provide a kind of remote contrast agent bolus device, require bolus administration of contrast agent under fluoroscopic monitoring to solve some the x-ray visualization existed in prior art and select the best opportunity to photograph, but, the problem easily operator damaged under being closely exposed to x-ray for a long time.
For realizing the purpose of this utility model, this utility model provides a kind of remote contrast agent bolus device, comprise: three Large Copacity syringe A, B, C, described B and C model is identical, the model of described A is more than or equal to described B, C model, the nipple of described A and B inserts sebific duct two ends respectively and ties up fixing formation one enclosed space, described B and C is put into plastics or metal box, the length of described box is that the B of the complete insert state of syringe piston adds the length that upper piston is drawn to the C of heap(ed) capacity mark, described box two ends all have " U " v notch v, the nipple of described B and C stretches out from described " U " v notch v respectively, the liquid of the low coefficient of viscosity is full of in advance in described sebific duct, the liquid being more than or equal to the described low coefficient of viscosity of C capacity is loaded in described A, the nipple of described C connects syringe needle.
This utility model, compared with prior art, draw materials easily, make simple, economical and practical, its " syringe-sebific duct-syringe " system once installs, can Reusability, without the need to sterilization.Meanwhile, adopt Indirect manual to inject, move in operating process, stop, delay, suddenly freely, bolus administration of contrast agent speed and dosage pole are convenient to control; Make pressure conduction medium with liquid, bolus infusion processes is continuously soft, is all better than similar applications electromechanical device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, this utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain this utility model, be not limited to protection domain of the present utility model.
As shown in Figure 1, the utility model discloses a kind of remote contrast agent bolus device, comprise: three Large Copacity syringe A, B, C, described B and C model is identical, the model of described A is more than or equal to described B, C model, the nipple of described A and B inserts sebific duct two ends respectively and ties up fixing formation one enclosed space, described B and C is put into plastics or metal box, the length of described box is that the B of the complete insert state of syringe piston adds the length that upper piston is drawn to the C of heap(ed) capacity mark, described box two ends all have " U " v notch v, the nipple of described B and C stretches out from described " U " v notch v respectively, the liquid of the low coefficient of viscosity is full of in advance in described sebific duct, the liquid being more than or equal to the described low coefficient of viscosity of C capacity is loaded in described A, the nipple of described C connects syringe needle.
It should be noted that, this device, adopt following steps to make:
1. get three Large Copacity syringes, be denoted as A, B, C respectively.Require B and C model identical (we select 20-50ml's).A is not less than B, C.C has to pass through sterilization.
2. get silica gel or rubber tube one, internal diameter is about 3mm, is about 5-6m.
3. make the tub (plastics or metal) that can be held B and C.Length is the C long (note: " B is long " " C is long " does not all comprise syringe nipple length herein) that the B of the complete insert state of syringe piston adds that upper piston is drawn to heap(ed) capacity mark.In tub, there are four " recessed " shape supports at two ends and middle part, and B, C syringe piston pain that fixes is used.Tub two ends separately have " U " row breach, stretch out for B, C nipple.
During use,
1. before radiography, A, B nipple inserted sebific duct two ends respectively and tie up fixing formation one closed system.Be full of the liquid of the low coefficient of viscosity in sebific duct in advance as tap water, in A, also load same liquid appropriate (being no less than the heap(ed) capacity of C).Like this, when promoting A piston, because in closed system, liquid volume does not change with pressure, same volume is released (impact that pressure can cause sebific duct to expand in theory is disregarded) by B piston.
The required contrast agent of suction in 2.C, good and sound syringe needle and angiography tube.Tub is placed in victim.
3. B, C are inserted tub with directions such as piston handles.Promotion A piston makes B piston exit and pushes against C.Operator can promote A piston further as required at a distance as control room under fluoroscopic monitoring, and pressure by liquid conductive in A-sebific duct-B system, and then promotes B and C piston, carries out radiography.Release contrast agent capacity directly to read by A in hands.Radiography is complete to be taken out outside A piston, and B piston can be shunk back simultaneously be left C, can take out B, C.As in C once fill contrast agent and still dislike not enough, can aspirate appropriate again, repeat above operation.
In a word, this device is drawn materials easily, makes simple, economical and practical.Its " syringe-sebific duct-syringe " system once installs, can Reusability, without the need to sterilization.Employing Indirect manual is injected, and moves, stops, delays, suddenly freely, bolus administration of contrast agent speed and dosage pole are convenient to control in operating process; Make pressure conduction medium with liquid, bolus infusion processes is continuously soft, is all better than similar applications electromechanical device.As long as it is not sebific duct is not meticulous, long, than directly increasing resistance with hand push note and not obvious X-ray machine device is other during operation.It is tired fixed that sebific duct and syringe nipple portion only need tie up with silk thread, can meet the pressure needs of general radiography completely.In sample, use internal diameter 3mm, the silica gel tube of long 5m does cost apparatus, at distance x-ray 4.5m place to upper urinary stone, block, more than 200 examples such as hydrops, tumor, cyst and deformity have carried out retrograde pyeloureterography and arteriography, all once success, obtains the other effect of directly injecting of same machine.Take the photograph choosing at random of sheet opportunity owing to ensure that, significantly improve the use value of radiography sheet, avoid rechecking to the unnecessary infringement of patient and burden, also protect doctor to greatest extent.As long as take the circumstances into consideration the fixation problem solving piercing needle and point of puncture, this device can be widely used in other multinomial dynamic arthrographies
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
