Description

An electric infusion stand

technical field

The invention relates to the technical field of medical supplies, more specifically, it relates to an electric transfusion stand.

Background technique

Infusion is also known as drip or hanging water. It is a large dose (more than 100ml for one administration) injection that is infused into the body by intravenous infusion. Usually packaged in glass or plastic infusion bottles or pouches without preservatives or bacteriostats. When in use, the drip rate is adjusted through the infusion set, and it enters the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. The development of intravenous infusion technology has experienced nearly 500 years of twists and turns, and gradually formed a complete system in the 20th century, becoming one of the most commonly used, most direct and effective clinical treatment methods.

The infusion stand is an erection tool for infusion. The infusion stand in the prior art is too high, and it is inconvenient for the short medical staff to take the infusion bottle for the patient. It is difficult for the short medical staff to operate. The infusion stand does not have a heating function, especially for children. Infusion in winter often causes discomfort to children because the medicine is too cold, which leads to boredom for children, which is not conducive to the smooth infusion of children. It is not conducive to children Patient's rehabilitation, in addition, in the prior art, the infusion stand with universal wheels vibrates greatly when moving, and the stability is relatively poor.

Contents of the invention

In view of the deficiencies in the prior art, the purpose of the present invention is to provide an electric infusion stand, which is convenient for short medical staff to use, and is convenient for short medical staff to take infusion bottles for patients, and has better shock absorption performance. At the same time, it has good stability, and the heating device can be used to heat the liquid medicine inside the infusion tube to prevent the patient from being uncomfortable due to the cold liquid medicine, especially for children. Warming is necessary, which can effectively avoid the discomfort of children patients caused by too cold liquid medicine, prevent children patients from getting bored with infusion, and benefit the smooth progress of infusion in children patients and the rehabilitation of children patients.

To achieve the above object, the present invention provides the following technical solutions:

An electric infusion stand, comprising a base, three sets of shock-absorbing assemblies are provided at the bottom of the base, universal wheels are provided at the bottom of the three sets of shock-absorbing assemblies, and a square outer sleeve is vertically installed in the center of the upper part of the base , the upper part of the square outer casing is equipped with a square support column that can move up and down, the top of the square support column is fixedly installed with a cross bar, and two hooks are symmetrically installed at the bottom of both ends of the cross bar. A threaded rod is screwed inside the bottom end of the support column, and the bottom end of the threaded rod is fixedly connected with the rotating shaft of the motor through a coupling. The motor is fixedly installed on the inner bottom of the base, and the inner bottom of the base is also provided with There is an accumulator, which is connected to the motor by wires.

By adopting the above technical scheme, the motor can drive the threaded rod to rotate, and the square support column cannot rotate under the restriction of the square outer casing. When the threaded rod rotates, the square support column can only move up and down inside the square outer casing, thereby realizing The height of the two hooks is electrically adjusted, so that the infusion stand is convenient for short medical staff to use, and it is convenient for the medical staff to take the infusion bottle for the patient.

Further, the three groups of shock absorbing assemblies are arranged at the bottom of the base at equal angles with the center point of the bottom of the base as the center of the circle. The shock absorbing assemblies include a cylinder, and the inside of the cylinder is provided with a first circular slider, Spring, the second circular slider and a support rod, the spring is installed between the first circular slider and the second circular slider, and the second circular slider is arranged on the first circular slider Below, and the bottom center of the second circular slider is fixedly connected to the upper end of the support rod, and the bottom end of the support rod extends to the outside of the bottom of the cylinder and is fixedly connected to the upper part of the fixed universal wheel bracket.

By adopting the above technical solution, the spring can be elastically expanded and contracted, so that it has better cushioning performance, the support rod can move up and down inside the cylinder, and the spring can convert the kinetic energy of the support rod into a spring during the up and down movement of the support rod. elastic potential energy, so that the shock-absorbing components have better shock-absorbing performance. Therefore, when the infusion stand encounters potholes during the movement of the ground, the infusion stand has better balance performance through the expansion and contraction of the support rod, and at the same time absorbs shock. The performance is good, preventing the battery inside the base from being damaged due to excessive vibration. In addition, the first circular slider and the second circular slider can ensure that the spring will not be deflected inside the cylinder, thereby ensuring shock absorption Component stability.
