Abstract
A speed regulating switch for an infusion apparatus belongs to the technical field of medical apparatuses and comprises a supporting frame (1), a squeezing board (2), a threaded rod (3) and a return spring (4). The speed regulating switch is characterized in that the inner wall of an upper board surface of the square supporting frame (1) is connected with the squeezing board (2) via the return spring (4), the squeezing board (2) matches with an inner cavity of the supporting frame (1), inner thread of a threaded hole of the upper panel of the supporting frame (1) is connected with the threaded rod (3), the upper end of the threaded rod (3) is provided with a handle, and the lower end of the threaded rod (3) is connected with an inner sleeve of a bearing (5) fixed to the upper surface of the squeezing board (2). The speed regulating switch has the advantages that squeezing force is easy to be adjusted and controlled by adopting a thread-rotation downward pressing mode to squeeze an infusion tube, so that accurate fine-adjustment of infusion speed can be realized, and the speed regulating switch is simple in operation and convenient in use.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of transfusion device speed-regulating switch.
Background technology
The speed-regulating switch of existing transfusion device is a roller structure, comprises framework and roller, and skewed slot is offered in the framework both sides, and roller places in the skewed slot by axle, and rotation roller moves may command to the depression degree of tube for transfusion along skewed slot, thereby regulates transfusion speed.The problem that exists is: operation control is not easily, when particularly transfusion speed being finely tuned, needs carefully rotation roller, is difficult to control rotation dynamics, is difficult to reach the requirement of fine adjustment speed yet.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of easy and simple to handle, and speed governing is the transfusion device speed-regulating switch accurately.
The purpose of this utility model is achieved in that this transfusion device is made up of carriage, stripper plate, threaded rod, back-moving spring with speed-regulating switch, square carriage upper face inwall is connecting the stripper plate that adapts with the carriage inner chamber by back-moving spring, the screwed hole female thread of carriage upper face is connecting the threaded rod that the upper end is provided with handle, and the threaded rod lower end links to each other with the bearing inner sleeve that is fixed on the stripper plate upper surface.
During use, rotate threaded rod and can push the tube for transfusion in the carriage, thereby transfusion speed is regulated by stripper plate; Loosening threaded rod under the effect of back-moving spring, just can alleviate the extruding to tube for transfusion after stripper plate rises.
Advantage of the present utility model: owing to adopt screw thread rotation to depress mode tube for transfusion is pushed, the extruding dynamics is regulated control easily, can realize the accurate fine setting to transfusion speed, and simple to operate, easy to use.
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 transfusion device is made up of carriage 1, stripper plate 2, threaded rod 3, back-moving spring 4 with speed-regulating switch, square carriage 1 upper face inwall is connecting the stripper plate 2 that adapts with carriage 1 inner chamber by back-moving spring 4, the screwed hole female thread of carriage 1 upper face is connecting the threaded rod 3 that the upper end is provided with handle, and threaded rod 3 lower ends link to each other with cover in the bearing 5 that is fixed on stripper plate 2 upper surfaces.
Claims (1)
1. transfusion device speed-regulating switch, form by carriage (1), stripper plate (2), threaded rod (3), back-moving spring (4), it is characterized in that square carriage (1) upper face inwall is connecting the stripper plate (2) that adapts with carriage (1) inner chamber by back-moving spring (4), the screwed hole female thread of carriage (1) upper face is connecting the threaded rod (3) that the upper end is provided with handle, and threaded rod (3) lower end links to each other with cover in the bearing (5) that is fixed on stripper plate (2) upper surface.
