Abstract

The utility model relates to an automatic speed regulating device for the transfusion. A casing body 1 can form a passage 2 for placing a transfusion tube, and the position corresponding to the passage is provided with a squeezing component 3 of the transfusion tube. Then, the squeezing component 3 is hinged with a swing rod 4 and the other end of the swing rod 4 is hinged on the casing body 1. An electric propelling mechanism used for swinging the swing rod 4 comprises an electric machine 8 and a speed reducer 9, wherein an output shaft 7 of the speed reducer is provided with a propelling component 6 which is matched with the swing rod 4 in a swinging way and the propelling component 6 is sheathed with a guide rod 5. The utility model has the advantage of reasonable design. The utility model is matched with an electronic control system to realize that the transfusion is controlled automatically, so that the utility model can reduce the workload of the medical personnel and enhance the accuracy of the transfusion.

Description

The transfusion automatic speed governor

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of transfusion automatic speed governor that is used for intravenous drip.

Background technology

At present, be used for the device that clinical vein instils, comprise infusion bottle, tube for transfusion, syringe, arrangements for speed regulation and Murphy type tube, tube for transfusion one end connects with infusion bottle, the other end connects with syringe, Murphy type tube, arrangements for speed regulation are located on the tube for transfusion, can observe infusion flow in Murphy type tube, and can lead to arrangements for speed regulation adjustment transfusion speed.Because its arrangements for speed regulation are manual types, in adjustment process, can only regulate by the liquid stream of observing in the Murphy type tube by rule of thumb, randomness is bigger, and is not only time-consuming but also inaccurate.

In addition, the known infrared detection head that utilizes cooperates the flow that can detect liquid with electronic control system, and the cooperation by electronic control system and arrangements for speed regulation can realize automatic speed regulation again.For the electronic control system part, a kind of " transfusion automatic monitoring instrument " that patent " 99224469.2 " provides mentioned, it is by infra-red sensing system, microprocessor, simple key entry system and liquid crystal display systems, actuator and acoustooptic alarm system are formed, user only need be by the data in advance input microprocessors such as transfusion speed of simple and easy key entry system of the present utility model with hope, whole infusion process is all under the monitoring of microprocessor, undertaken by the program that sets in advance, thereby realization speed is default, show in real time, automatic speed regulation, abnormal conditions are reported to the police automatically, immediately or time-delay multiple function such as dam.How this patent is for realizing the not significantly prompting of controlling liquid flow, and therefore, the present utmost point need provide a kind of and can cooperate with electronic control system and arrangements for speed regulation simple in structure.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of transfusion automatic speed governor simple in structure is provided, and utilizes and can realize itself and cooperating of electronic control system control transfusion automatically.

The purpose of this utility model can realize by following technical measures: this speed regulator comprises housing, housing is formed with the passage of placing tube for transfusion, the respective channel place is provided with the tube for transfusion extrusion, extrusion is hinged with fork, the fork other end is hinged on the housing, and is provided with the electronic propulsive mechanism that is used for the fork swing.

Propulsive mechanism comprises motor, decelerator, and the output shaft of decelerator is provided with the projectile that cooperates with fork swing, and projectile cooperates with external screw thread on the output shaft by female thread, and projectile is set with guide post, and the guide post two ends are fixed on the housing.

Housing divides left and right sides two parts along the trend of passage, is hinged to be one, can open along the hinged place and close.

This utility model is reasonable in design, utilizes electronic propulsive mechanism to cooperate with the tube for transfusion extrusion, regulates tube for transfusion circulation caliber size, the control infusion flow, infuse with realizing automatic control cooperating of electronic control system, thereby can alleviate medical personnel's workload, improve the accuracy of transfusion.It is simple in structure, making is easy, cost is low, suitable applying.

The specific embodiment

With reference to Fig. 1, Fig. 2, housing [1] is formed with the passage [2] of placing tube for transfusion from top to bottom, and housing [1] divides two parts along the trend of passage [2], is hinged to be one, can open along the hinged place and close, and is easy to install and use.The respective channel place is provided with tube for transfusion extrusion [3], and the compressive plane of this extrusion [3] is an arcwall face, sees Fig. 2, and extrusion [3] is hinged with fork [4], and fork [4] other end is hinged on the housing [1], and is provided with the electronic propulsive mechanism that is used for the fork swing.

Propulsive mechanism comprises motor [8], decelerator [9], and the output shaft of decelerator [7] is provided with the projectile [6] that cooperates with fork [4] swing, and projectile [6] is provided with groove [10], and fork [4] may be stuck in groove [10] lining, makes fork [4] swing accurate positioning.Projectile [6] cooperates with external screw thread on the output shaft [7] by female thread, and projectile [6] is set with guide post [5], and guide post [5] two ends are fixed on the housing [1].Utilize electronic control system control motor positive and inverse, promote projectile [6] and move up and down, fork [4] is then along the hinged place swing, and the extrusion [3] hinged with fork [4] pushes tube for transfusion, reaches to regulate tube for transfusion circulation caliber size, control infusion flow.

This utility model can be installed on the tube for transfusion easily, sees Fig. 3, and during installation, earlier fixing positioning piece [12] below the Murphy type tube on tube for transfusion [11] is opened housing [1] along the hinged place, is enclosed within above the keeper [12] of tube for transfusion [11], then can close.Realize control automatically by infrared detection head, electronic control system again.Electronic control system can adopt described in patent " 99224469.2 ".
