Description

Cardio angiographic unfolder

Technical field

The utility model relates to a kind of medical instrument, specifically a kind of cardio angiographic unfolder.

Background technique

Clinically in the therapeutic process of cardiovascular disease, in order to more accurately understand cardiovascular concrete condition, need Contrast examination is carried out to blood vessel, specific way is to be injected into contrast agent in blood vessel by injector, and the prior art is made Shadow agent injector is actually the syringe of the prior art, and since the push-pull rod handle of syringe is smaller, and contrast agent is viscous Consistency is higher, and the difficulty injected is larger, and fatigue will be generated by injecting contrast agent palm for a long time, and hand muscle is ached, time-consuming to take Power, tired hand injection will generate certain shaking, even if hand is not at fatigue state, patient may also generate shaking, because Injection-tube is easy displacement when this operation, so that syringe needle be made to shift, increases the workload that personnel are injected in medical matters, injection-tube is in patient It fixes in vivo unstable, it is easy to deviate from, also bring difficulty to diagnoses and treatment.

Although current cardio angiographic unfolder type is more, it is difficult to fundamentally to solve above-mentioned technology to ask Topic.

Utility model content

To solve the above problems, the purpose of the utility model is to provide a kind of cardio angiographic unfolders.

To achieve the above object, cardio angiographic unfolder is that a kind of driven by decelerating motor is realized to the utility model The assist device of boosting, injection tube body including cuboid and is mounted on the deceleration promoted in the motor casing of end above injection tube body Motor, the discharge end setting for injecting tube body is tapered, and funnel shaped discharge port, the adjustable pipe of discharge port connection is arranged in inside Pipe fitting be connected to the feed end of check valve, the discharge end of check valve is connected to by a fixing pipe with injection needle, unidirectionally Strip fixed cable tie of the both ends with velcro primary and secondary face, convenient for fixing check valve, injection-tube are fixed on the lateral wall of valve Threaded rod one end of body inner horizontal is located in the side wall of injection tube body after running through partition, and partition and injection tube body promote between end For gear cavity, be fixed with driven gear on the threaded rod inside gear cavity, driven gear then with the drive in geared motor output shaft Moving gear is meshed, and when decelerating motor rotation, can be rotated by sliding tooth wheel drive driven gear, and then drive threaded rod Rotation, threaded rod is arranged on the part of helicitic texture then through the piston push plate for having inside to be embedded with inner thread sleeve, and piston pushes away The two sides of plate are all covered with one layer of rubber piston plate, and piston push plate, the shape in rubber piston plate section and injection internal diameter of tube body are cut The shape in face is identical, is all quadrangle, pushes piston push plate, rubber piston plate horizontal direction when threaded rod rotates in this way The right side moves downward, and the evenly arranged mini-fan blade of multi-disc, miniature wind are fixed in the screw thread rod end surface inside discharge port It is additionally provided with Mini-type spiral blade on the end face of fan leaf, pushes piston push plate, rubber piston plate horizontal direction when threaded rod rotates Right or when move downward, mini-fan blade and Mini-type spiral blade also rotate with it, and are pushing piston push plate, rubber living When seben squeezes internal contrast agent, mini-fan blade and Mini-type spiral blade are rotated the contrast agent at discharge port position The feed end for pushing adjustable pipe to, plays the role of boosting, can effectively increase the discharging ability of discharge port, can not only prevent The blocking of discharge port, moreover it is possible to promote the extrusion of contrast agent, two control switches of motor casing upper surface setting control deceleration respectively A control switch is only opened in the rotating forward and reversion of motor every time, passes through control switch i.e. controllable piston push plate, rubber piston plate It is moved to the left or right, and then realizes boosting or sucking, decelerating motor is connected as decelerating motor with attaching plug by conducting wire and mentions Power supply source, the bottom for injecting tube body are additionally provided with cushion block, are used to support injection tube body.

Due to using the technology described above, when use, check valve is tied up with fixed cable tie at the position to be injected, is It convenient for injection, ties up when on the arm of people, fixed cable tie cannot be too tight, only require that check valve cannot slide, or will Fixed cable tie is tied up on the bed fence of patient, then again pricks injection needle on human body, sticks disinfection at injection needle position Cotton etc., as long as patient is motionless in this way, injection needle and fixing pipe remain static always, in the fixed function of fixed cable tie Under, even if check valve connection pipe fitting is injected, no matter how adjustable pipe is placed, is pullled, even if pullling excessively, pipe fitting is just It can fall off, due to the effect of check valve, the intracorporal blood of people can not flow out, however fixing pipe and injection needle will not all move, The generation that effectively can fundamentally prevent inclined needle phenomenon, is injected convenient for medical worker；Entire injection process, it is only necessary to The control switch that control promotes is pressed, drives piston push plate, rubber piston plate to realize injection by decelerating motor, is not necessarily to people Work pushes more labor-saving.
