Description

Portablely exempt to hang transfusion device and transfusion bag

Technical field

This utility model relates to a kind of armarium, specifically is meant a kind of portable exempt to hang transfusion device and and the matching used transfusion bag of transfusion device.

Background technology

At present, in hospitality industry, traditional infusion model great majority are that transfusion bag or infusion bottle are hung on the drip stand, utilize the downward dropping liquid of action of gravity of medicinal liquid self, thereby make medicinal liquid inject vein.In the overall process of this infusion model, must remain medicine bottle or medicated bag relative altitude to human transfusion part.For this reason, while move when infusing when needs of patients, then need other people to assist to hold high medicine bottle and follow.

The utility model content

The purpose of this utility model is to overcome the defective of present infusion model, provide a kind of simple in structure, carry and infusion set easy to use and that needn't hang.

For achieving the above object, solution of the present utility model is:

This utility model relates to a kind of portable exempt to hang transfusion device and supporting with it transfusion bag.

Described transfusion device is a cylindrical box, is made up of upper shell, pressure mechanism and lower house.Spin for screw thread between upper shell and lower house.Described pressure mechanism is combined into one successively by spring fixed end base, spring and camber of spring end platen, and pressure mechanism is fixedly mounted in the upper shell.There is one on the sidewall of lower house and is used for the otch that tube for transfusion therefrom passes through.

Described transfusion bag is a kind of circular bag, is connected with tube for transfusion on the transfusion bag.The lower house internal diameter of the diameter of transfusion bag and transfusion device is complementary.On tube for transfusion, be provided with medicine-pouring port, clip, defecator and entry needle interface successively.

Utilize spring pressure to push transfusion bag owing to this utility model employing is this, make medicinal liquid inject the infusion model of human body, exempted the requirement that transfusion bag must hang.The advance and retreat control spring pressure size of utilizing upper shell and lower house screw thread to spin is regulated the speed speed of transfusion with this.The lower house internal diameter of the diameter of transfusion bag and transfusion device is complementary, and inner edge is complementary bottom the camber of spring end platen of spring and the lower house, can push medicinal liquid fully totally like this.This utility model is simple in structure, and volume is little in light weight, patient's transfusion in moving outstanding showing conveniently particularly, need not other people and holds transfusion bottle high and follow.Even infuse under static state, the patient also can obtain big freedom and comfort level.

The specific embodiment

Further specify this utility model below in conjunction with specific embodiment.

As shown in Figure 1, this utility model relates to a kind of portable exempt to hang transfusion device 1 and supporting with it transfusion bag 2.Shown in Figure 2 is the decomposing schematic representation of transfusion device, and as depicted in figs. 1 and 2, described transfusion device 1 is a cylindrical box, is made up of upper shell 11, pressure mechanism 12 and lower house 13.Upper shell 11 is fastened on the lower house 13, is screwed in together by upper shell screw thread 111 and lower house screw thread 131.Lower house 13 can be a transparent body, the convenient transfusion situation of observing.Lower house 13 bottom inner edges are up big and down small planar trapezoidal cone shape.A bar shaped otch 132 is longitudinally arranged on the sidewall of lower house 13, and the tube for transfusion 21 that is used on the transfusion bag 2 therefrom passes through.Described pressure mechanism 12 is loaded between upper shell 11 and the lower house 13.By Fig. 2 and shown in Figure 4, pressure mechanism 12 is made of tower spring 121, spring fixed end base 122 and camber of spring end platen 123.Spring 121 is positioned at the centre of spring fixed end base 122 and camber of spring end platen 123.Pressure mechanism 12 is fixed in the upper shell 11 by the connection of the bolt between spring fixed end base 122 and upper shell 11 end faces.Respectively there are four gap at edge at spring fixed end base 122 and camber of spring end platen 123, link to each other by shallow slot between the corresponding gap, two steel wires are reined in gap and shallow slot, spring fixed end base 122, spring 121 and camber of spring end platen 123 are fastened be integral.And, parallel between spring fixed end base 122 and the camber of spring end platen 123.Like this, the final position of camber of spring end platen 123 can smooth bottom to lower house 13.Connect with screw between the spring fixed end base 122 of pressure mechanism 12 and upper shell 11 end faces, pressure mechanism 12 is fixedly mounted in the upper shell 11.The spring fixed end base 122 of pressure mechanism 12 is a disk.Camber of spring end platen 123 is up big and down small planar trapezoidal circular cone body disc, is complementary with lower house 13 bottom inner edges, so that camber of spring end platen 123 is pressed onto lower house when bottom, and can be clean the extruding of the medicinal liquid in the transfusion bag 2.

As shown in Figure 3, described transfusion bag 2 is a kind of circular bag, and lower house 13 internal diameters of the diameter of transfusion bag 2 and transfusion device 1 are complementary, and transfusion bag 2 placing flat are in lower house 13 bottoms during use.On transfusion bag 2, be connected with tube for transfusion 21.On tube for transfusion 21, be provided with medicine-pouring port 22, clip 23, defecator 24 and entry needle interface 25 successively.The effect of defecator 23 is filtrate and filter gas.Clip 24 is in order to decontrol or to clamp tube for transfusion 21.Medicine-pouring port 22, clip 23 and defecator 24 all are a kind of existing parts, no longer describe in detail in this literary composition.

When this utility model uses, earlier transfusion bag 2 is positioned in the lower house 13, the upper shell 11 that will have pressure mechanism 12 then is threaded onto in the lower house 13, and the camber of spring end platen 23 of spring 121 is pressed on the transfusion bag 2.Pressure effect by spring 121 is injected in the human body medicinal liquid.The advance and retreat control spring pressure size of utilizing upper shell 11 and lower house 13 screw threads to spin is regulated the speed speed of transfusion with this.

Above embodiment is preferred embodiment of the present utility model, only supply the usefulness of explanation this utility model, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or variation.As only the external shape of transfusion device being done simple the change, therefore, all technical schemes that are equal to also should belong to category of the present utility model.
