Food injection device for swallowing contrast examination

Abstract

The utility model relates to the field of medical equipment, and particularly discloses a food injector device for swallowing contrast examination, which comprises an empty cylinder and a piston, and the piston is slidably arranged in the empty cylinder to form an injector structure. A first bulge is arranged on the inner side wall of the empty cylinder; the piston comprises a piston head and a piston rod, and a plurality of second protrusions are arranged on the side face of the piston rod at different heights and in different directions. By rotating the piston, when the piston is lifted, different second protrusions and first protrusions collide with each other, and therefore displacement is limited. By arranging the first protrusions and the second protrusions, due to the fact that the heights of the second protrusions are different, and the lifting heights of the piston are different when the second protrusions collide with the first protrusions, different quantities of fluid food can be quantitatively extracted according to needs, the situation of insufficient extraction or excessive extraction is avoided, and convenience and practicability are achieved. The disposable syringe can be formed by transforming a ready-made syringe, the first protrusion and the second protrusion can be ready-made screws and other small parts, materials are convenient to obtain, cost is low, and manufacturing is easy.

The inner side wall of the barrel is provided with a first protrusion; the piston includes a piston head and a piston rod, and a plurality of second protrusions are arranged on the side surface of the piston rod at different heights and in different directions; by rotating the piston, different second protrusions can collide with the first protrusion to limit displacement when the piston is lifted.

[0006] Further, the piston rod is composed of a plurality of circumferentially distributed pieces, and a space is provided on some or all of the pieces for the first protrusion to pass through.

[0007] Further, the first protrusion is located at the upper part of the inner side wall of the barrel.

[0008] Further, the first protrusion is located at the upper part of the inner side wall of the barrel, and the space is located at the upper part of the piston rod, and the space is level with the first protrusion when the piston is at the bottom end.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model sets the first protrusion and the second protrusion, and the height of the second protrusion is different, so that the height of the piston is different when the second protrusion collides with the first protrusion, so that different amounts of fluid food can be extracted quantitatively according to the needs, and the situation of less or more extraction can be avoided, which is convenient and practical. The utility model can be modified using existing syringes, the first protrusion and the second protrusion can be small parts such as existing screws, which is convenient to obtain, low in cost and easy to manufacture.

[0015] In the description of the present embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the utility model product is used, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0016] The terms "first", "second", and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "provided", "connected", "connected" should be broadly understood.

[0018] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below in combination with the drawings.

[0019] Please refer to Figs. 1 to 3The embodiment discloses a swallowing radiography examination food injection device, which comprises a hollow cylinder 100 and a piston 200, the piston 200 is slidably arranged in the hollow cylinder 100, and the piston 200 and the hollow cylinder 100 form a syringe structure. A first protrusion 110 is arranged on the inner side wall of the hollow cylinder 100; the piston 200 comprises a piston head 210 and a piston rod 220, a plurality of second protrusions 221 are arranged on the side surface of the piston rod 220 in different heights and different directions; by rotating the piston 200, different second protrusions 221 can collide with the first protrusion 110 to limit displacement when the piston 200 is lifted. Since the heights of the second protrusions 221 are different, the height of the piston 200 lifted when the second protrusions 221 collide with the first protrusion 110 is different, so that different amounts of fluid food can be quantitatively extracted according to requirements, and the situation of less extraction or more extraction is avoided, and the device is convenient and practical. The embodiment can be modified by using an existing syringe, the first protrusion 110 and the second protrusion 221 can be small parts such as existing screws, the parts are convenient to obtain, the cost is low, and the manufacturing is simple.

[0020] As a further scheme of the embodiment, the piston rod 220 is composed of a plurality of circumferentially distributed sheet bodies, and a space 222 for the first protrusion 110 to pass through is arranged on part or all of the sheet bodies. The sheet body structure is a general structure of the piston 200 of an ordinary syringe, and the embodiment is directly modified on the basis of the general structure.

[0021] As a further scheme of the embodiment, the first protrusion 110 is located on the upper portion of the inner side wall of the hollow cylinder 100, and the corresponding second protrusion 221 can also be located close to the upper portion, so that the adjustment and quantification are more convenient to observe.
