Abstract
The invention relates to a bag type flexible balancing medical infusion pump which is characterized in that a liquid inlet pipe fixer (2) and an infusion bag (3) are connected with a liquid inlet pipe (1) in turn, wherein the infusion bag (3) is fixed by an infusion bag positioning frame (4) and is arranged in an extruding plate of a flexible tooth-shaped extruding pump (5), and a liquid outlet pipe (7) of the infusion bag (3) is fixed by a liquid outlet pipe fixer (6). The infusion pump provided by the invention is used for solving the problems of mass flow infusion and low-pulse infusion. Due to the physical characteristics, the other infusion pipes are not mistakenly used in a bag type infusion pump, the medical negligence is further avoided and the infusion precision is increased.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of medical transfusion equipment, especially infusion pump.
Background technology
Medical apparatus and instruments belongs to special industry, the various equipment be applied to, and requires that safety is very high.To infuse in addition application, have multiple situation: be such as heavy dose of, long-time etc., current most infusion pump is infused by squash type, and transfusion caliber is very little, can cause pulse of necessarily infusing, can not carry out heavy dose of infusion.
Summary of the invention
The object of the invention is to the shortcoming overcoming above-mentioned prior art, provide a kind of bellows infusion pump, this infusion pump adopts modularized design, meet existing infusion function requirement, and greatly reduce transfusion pulse, make it very mild and carry out infusion, effectively solve the problem of transfusion pulse.By bellows extruding transfusion, greatly improve transfusion speed, reduce transfusion pulse.
The object of the invention is to solve by the following technical programs:
A kind of bellows infusion pump, it is constructed as follows: feed tube (1) connects feed tube holder (2), transfusion capsule (3) successively, transfusion capsule (3) fix with transfusion capsule locating rack (4) and be placed in the stripper plate of flexible tooth shape extrusion pump (5), the drain pipe (7) of transfusion capsule (3) uses drain pipe holder (6) fixing.
Infusion pump of the present invention, is fixed by feed tube holder (2) and drain pipe holder (6) and is demarcated special liquid-transport pipe-line.The compressional movement of transfusion capsule is completed by transfusion capsule locating rack (4) and corresponding flexible dentation extrusion pump (5).Determine that liquid-transport pipe-line is uniquely accurate by feed tube holder (2), drain pipe holder (6) and transfusion capsule locating rack (4).By transfusion capsule locating rack (4) and corresponding flexible dentation extrusion pump (5) by adding infusion solutions sectional area, strengthening infusion flow rate, ensure transfusion precision and reduce pulse of infusing.
Infusion pump of the present invention, the tooth-shape structure that wherein flexible dentation extrusion pump (5) is arranged by the continuous and parallel that two planes are relative forms, make the transfusion capsule be between two plate be formed continuously extruded by this relative to the wriggling of notched plate, and then the force direction that the liquid in capsule is wriggled according to tooth plate is promoted.
Infusion pump of the present invention, with the major part that infuse capsule (3) and flexible dentation extrusion pump (5) are invention, it is run by running gear, and running gear comprises control system, actuating unit, checkout gear, warning and safety device and input and interactive device.
Wherein actuating unit application linear peristaltic pump, the bellows structure that middle extrusion application is special, as Fig. 1.Bellows sectional area is 10 times of round type sectional area, so under the equal rotating speed of pump, the flow of bellows is 10 times of round type, so our transfusion speed, can reach original 10 times.In like manner, when under identical infusion flow rate, the rotating speed of bellows infusion pump only has original 1/10, so the impulse wave cycle is 10 times of traditional infusion pump, impulse wave is just much mild.We are by reducing in addition, accomplish further buffering, greatly can reduce impulse wave again.
The present invention has following beneficial effect:
Compared with traditional infusion pump, native system not only can carry out very mild infusion, effectively solves the problem of transfusion pulse, also by bellows extruding transfusion, greatly improves transfusion speed, can be applied to urgent blood transfusion; During extruding transfusion capsule, as Fig. 2, the contact in face and face, transfusion deformation quantity and recovery are better than circular pipeline.Meanwhile, due to physical characteristic, other infusion pipeline can not be misused in bellows infusion pump, just further avoid malpractice, improve transfusion precision.
Accompanying drawing explanation
Fig. 1 is syringe structure figure of the present invention.Wherein
Feed tube (1), feed tube holder (2), transfusion capsule (3), transfusion capsule locating rack (4), flexible dentation extrusion pump (5), drain pipe holder (6), drain pipe (7).
Fig. 2 is the fashion of extrusion of infusion pump of the present invention and fashion of extrusion comparison diagram of the prior art.
Detailed description of the invention
Below in conjunction with accompanying drawing, 1 couple of the present invention is described in further detail:
By feed tube holder (2), transfusion capsule locating rack (4) and drain pipe holder (6), the special infusion pipeline of installation; By flexible dentation extrusion pump (5) motion of driven by motor, extruding transfusion capsule (3).Wherein flexible dentation extrusion pump (5) has 12 to extrude joints, and having moved one-period according to sine wave in 12 extruding joints, completes an infusion process.The tooth-shape structure that wherein flexible dentation extrusion pump (5) is arranged by the continuous and parallel that two planes are relative forms, make the transfusion capsule be between two plate be formed continuously extruded by this relative to the wriggling of notched plate, and then the force direction that the liquid in capsule is wriggled according to tooth plate is promoted.
