Description
Affiliated technical field
This utility model belongs to medical appliance, particularly a kind of liquid food device that can take food for the liquid food patient convenient in clinical.
Background technology
At present, in clinical middle liquid food patient feed, usually use the 50ml intravenous injector to patient injection, be input in patient's stomach through nasal feeding tube.Mainly in the practice there are two problems: the one, with the injection of 50ml intravenous injector, used to be prone to several times the syringe plug and to move difficult phenomenon, must be with energetically pushing, the injection plug could move; The 2nd, toward the nasal feeding tube injection, this connected mode is insecure with the 50ml intravenous injector, and syringe is connected segregation phenomenon with nasal feeding tube when often appearing at injection, and the nutrients such as food, water are extruded to it and locate.
The utility model content
The technical problems to be solved in the utility model provide a kind of piston move at the uniform velocity smooth, with nasal feeding tube connected mode liquid food device firmly.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of liquid food device, it comprises columned empty cylinder and piston within it, piston is provided with sealing ring, front end at empty cylinder is provided with nipple, the inner chamber of nipple communicates with the inner chamber of empty cylinder, be characterized in: the piston back is fixed with is with externally threaded threaded rod, rear end at threaded rod is provided with rocking handle, be provided with external screw thread at empty cylinder rear portion, after be covered with female thread, empty cylinder and bonnet are by being threaded, the bonnet center is provided with tapped hole, threaded rod passes the hole at bonnet center, and both are by being threaded.
Front end at nipple is provided with the spring groove that rises, and the rear end is provided with externally threaded screw thread convex, is placed with the spring that rises on the spring groove that rises, and the screw thread convex is provided with a with it nut by being threaded.
Empty cylinder is transparent, is provided with scale at empty drum outer wall face.
The utility model has the advantages that: laborsaving, safety when taking food to the liquid food patient makes things convenient for clinical practice.
Description of drawings
Accompanying drawing is the sectional structure schematic diagram of a kind of embodiment of this utility model
The specific embodiment
As shown in drawings, a kind of liquid food device, it comprises columned empty cylinder 1 and piston within it 3, piston 3 is provided with sealing ring 4, front end at empty cylinder 1 is provided with nipple 6, the inner chamber of nipple 6 communicates with the inner chamber of empty cylinder 1, piston 3 back are fixed with is with externally threaded threaded rod 2, be provided with rocking handle 5 in the rear end of threaded rod 2, be provided with external screw thread at empty cylinder 1 rear portion, bonnet 7 is provided with female thread, empty cylinder 1 and bonnet 7 are by being threaded, bonnet 7 centers are provided with tapped hole, and threaded rod 2 passes the hole at bonnet 7 centers, and both are by being threaded.Front end at nipple 6 is provided with the spring groove 9 that rises, and the rear end is provided with externally threaded screw thread convex 8, is placed with the spring 10 that rises on the spring groove 9 that rises, and screw thread convex 8 is provided with a with it nut 11 by being threaded.Empty cylinder 1 is transparent medical plastic, is provided with scale in empty cylinder 1 outside wall surface, is convenient to control food-intake.Drive threaded rod in the rocking handle mode of shaking and rotate, and then drive piston and move, extrusion fluid food is taken food to patient, mobile at the uniform velocity, active force is large, makes things convenient for the control progress.Bonnet has firm threaded rod and guarantees that threaded rod drives piston and moves along columned empty cylinder centrage, and the Supramammillary spring that rises makes it more firm with linking to each other of nasal feeding tube with nut structure.
