Abstract
The utility model discloses an intravenous infusion speed control switch which belongs to the technical field of medical appliance and is improved on the basis of a conventional infusion speed control switch. The intravenous infusion speed control switch is characterized in that a keep plate is hinged on the upper head surface of an infusion tube channel at the front end of the switch; a support spring is connected between the other end of the keep plate and the outer wall of the upper head surface of the infusion tube channel at the front end of the switch; a triangular blade is fixed at the underside of the keep plate; and a through hole matching with the triangular blade is arranged on the upper head surface of the infusion tube channel at the front end of the switch. Compared with the current infusion tube disfigurement methods, the intravenous infusion speed control switch is simple in structure and convenient to use and can disfigure the infusion tube once on site without using other disfiguring tools, thereby preventing the transfusion tube from being recovered for reuse.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of speed of intravenous infusion gauge tap that can unmake to the tube for transfusion scene.
Background technology
The disposable transfusion device that uses in transfusion at present mainly comprises tube for transfusion, Murphy's burette, transfusion speed gauge tap and transfusion needle, and switch is sleeved on the tube for transfusion, by rotating pinch roller control transfusion speed.In order to prevent repeated use to disposable transfusion device, avoid cross infection, being used to complete the back requires to be unmake in the disposable transfusion device scene, the present method of unmaking is: with shears transfusion device is cut into several sections or put into the machine of unmaking and smash by the nursing staff, in case illegal businessman reuses after reclaiming, this quadrat method operation inconvenience needs to be equipped with instrument in addition or can not to unmake at the scene when unmaking, even forgets and unmake.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and not only can control transfusion speed, and the speed of intravenous infusion gauge tap that can also unmake to the tube for transfusion scene.
The purpose of this utility model is achieved in that this speed of intravenous infusion gauge tap is to improve to form on the basis of traditional infusion S/CO, articulated pressing plate on the switch front end tube for transfusion passage upper surface, be connected with support spring between the pressing plate other end and the switch front end tube for transfusion passage upper surface outer wall, triangular blade is being fixed in the pressing plate bottom surface, and switch front end tube for transfusion passage upper surface is provided with the through hole that adapts with triangular blade.
After transfusion finishes, push pressing plate, the through hole that the triangular blade above the pressing plate passes the switch upper front end is inserted on the interior tube for transfusion of switch, spurs tube for transfusion then, and tube for transfusion can be broken away, and reaches the purpose of unmaking.
Advantage of the present utility model: compare with the present tube for transfusion method of unmaking, simple in structure, easy to use, do not re-use other the instrument that unmakes, just can be on-the-spot disposable tube for transfusion be unmake, avoid recycling.
Description of drawings
Accompanying drawing is a structure chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this speed of intravenous infusion gauge tap is to improve to form on the basis of traditional infusion S/CO, articulated pressing plate 2 on the switch 1 front end tube for transfusion passage upper surface, be connected with support spring 3 between pressing plate 2 other ends and the switch 1 front end tube for transfusion passage upper surface outer wall, triangular blade 4 is being fixed in pressing plate 2 bottom surfaces, and switch 1 front end tube for transfusion passage upper surface is provided with the through hole that adapts with triangular blade 4.
