Abstract
The utility model relates to a device which infuses medium to the human body, which belongs to the medical device and is especially suitable for the vein bolus of the medical application. The utility model is characterized in that a platform with a through hole is fixed on a bracket, and a plurality of shield bodies are fixed above the platform. The inner side of each shield bodies is provided with a plurality of balancing weight blocks whose sizes andshapes are matched with the shield body. The utility model has the advantages of simple structure, low cost and simple and safe operation, and is a vein bolus device which can provide constant bolus power.
Description
This utility model relates to a kind ofly imports the intravital apparatus of people with medium, belongs to medical apparatus and instruments, is specially adapted to medical vein and injects.
When in hospital, carrying out the intravenous injection infusion treatment at present for patient, often with the elastic force of rubber band as the powered injector push-rod, liquid is imported in the patient body.Because the size of rubber band elastic force is directly proportional with its length, along with the carrying out of injecting, it is more little that power also becomes more, causes inject inhomogeneous, and patient is not felt well.Also there is the micro-machine of employing in the hospital that has as injecting power, and both cost was higher, and the fluctuation because of voltage makes that the power of injecting fluctuates again.
It is a kind of simple and reasonable for structure, with low cost, easy and simple to handle that the purpose of this utility model is to provide, and constant intravenous injection device of injecting power can be provided.
The purpose of this utility model realizes in the following manner: the platform that has a through hole is fixed on the support, and the platform upper fixed has some block bodies, the balancing weight that the block body inboard has some sizes and shape and block body to match.
Described block body can be a tubular bodies, and described balancing weight is the disk shape, and perhaps block body is to be no less than two rod objects, and described balancing weight is provided with limited mouth.
Described block body can adopt transparent material to make, and is provided with the opening of glove in a side of tubular bodies.
The utlity model has simple in structure, with low cost, easy and simple to handle, safety as can be seen from above scheme, the constant power of injecting can be provided in whole injection process, reduce patient's discomfort and nursing staff's characteristics such as trouble.
Specify structure of the present utility model below in conjunction with embodiment and accompanying drawing.
Fig. 1 is a kind of main sectional structure sketch map of the present utility model.
Fig. 2 is the vertical view of another kind of structure of the present utility model.
Embodiment 1: referring to accompanying drawing 1, platform 2 horizontal fixed that have a circular hole are on support 1, and the barrel bore of the pore size of circular hole and syringe 8 matches on the platform 2, again less than the syringe barrel edge of turning up.Platform 2 is connected with a tubular block body 3, and block body 3 can adopt transparent material such as lucite to make, and is provided with glove opening 6 in tube wall one side, so that balancing weight 4 picks and places the circular balancing weight 4 that block body 3 inboards have several sizes and block body 3 to match during injection.When carrying out intravenous injection, the syringe that injects medicine is vertically put into the circular hole of platform 2, and outer the turning edge of syringe is stuck in the circular hole place just, lays vertically above injector push-rod then that to put pouring weight 4 some, rely on the gravity of balancing weight 4 to promote push rod, thereby medicine is injected in the patient body.Block body 3 has limited balancing weight 4 motion in the horizontal direction, guarantees that 4 of balancing weights move straight down along the injector push-rod direction of motion, thereby finishes the injection task.Because the gravity of balancing weight 4 is constant, and be whole unique power of injecting device, guaranteed the constant of thrust in the infusion process, patient can be according to the needs of self health and treatment simultaneously, at any time easily by adjusting the weight of balancing weight 4, regulate injection speed.
Embodiment 2: block body 3 among the embodiment 1 and balancing weight 4 can adopt other form, be arranged on as two vertical bars 3 on the platform 2 of band through hole, the spacing of two straight-bars is slightly larger than the outer of syringe barrel and turns edge, and on described balancing weight 4, be provided with corresponding limited mouth 6, to guarantee balancing weight 4 safety in whole injection process, stably vertical on block body 3, force in injector push-rod (referring to accompanying drawing 2) consistently.
