Description

Micropump for controlled analgesia

Technical Field

The utility model belongs to the technical field of medical instrument, in particular to a micropump for controlling analgesia.

Background

In the clinical transfusion work in hospitals, some patients need to transfuse 1-10 ml of medicine liquid per hour, for example, painless childbirth and some operations need postoperative analgesia, and although local anesthesia can be adopted in painless childbirth to relieve the pain of the operators, unnecessary injuries can be caused to the operators, and even postoperative complications are easy to occur. Some operations can relieve pain by means of injection of pain relieving needles after operation, so that the system applied by a patient can be injured, and the requirement of micro-infusion cannot be met.

At present, in order to accurately, slightly, uniformly and continuously input a small amount of liquid medicine into a patient, a micro pump is generally adopted, but the existing micro pump completes the liquid input and output through three cams on the same axis, and has a complex structure and is not accurate enough.

SUMMERY OF THE UTILITY MODEL

To the technical problem that the structure that exists is complicated and can not the accurate infusion of accomplishing among the prior art, the utility model provides a micropump for controlling analgesia, simple structure, infusion volume is accurate, can guarantee that patient's postoperative analgesia is used.

In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a micropump for controlling analgesia, includes the pump body and the feed liquor pipe, pump line and the drain pipe that connect gradually, feed liquor pipe and drain pipe are parallel to each other, be equipped with the cam by actuating mechanism driven between feed liquor pipe and the drain pipe, pump line, feed liquor pipe and drain pipe are connected with briquetting, second flashboard and the first flashboard with the cam contact respectively to the rotation through the cam drives briquetting, first flashboard and second flashboard respectively and realizes the entering and the output of liquid.

Preferably, the driving mechanism comprises a motor and a gear, so that an output shaft of the motor drives the gear driving cam to rotate.

Preferably, the liquid inlet pipe, the pump pipe and the liquid outlet pipe are connected with each other through pipe joints.

Preferably, the briquette is T-shaped.

The novel micropump for controlling analgesia has the following beneficial effects: the utility model discloses simple structure through the cam rotation 360 to accomplish opening and closing and promote the briquetting of two flashboards respectively and realize the suction liquid of pump line and a duty cycle of extrusion liquid, realized that the infusion volume in the unit interval is adjusted to the stroke through the duty cycle number of times of unit interval and briquetting, reduced the space that occupies the medicine box, strengthened the liquid medicine storage capacity, guaranteed the patient trace and long-time infusion needs.

Detailed Description

So that those skilled in the art can better understand the technical solution of the present invention, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in figure 1 and figure 2, the embodiment of the utility model discloses a micropump for controlling analgesia, including the pump body 1 with feed liquor pipe 2, pump line 6 and the drain pipe 7 that connects gradually, feed liquor pipe 2, pump line 6 and drain pipe 7 are connected through coupling 3 between two liang. Feed liquor pipe 2 and drain pipe 7 are parallel to each other, be equipped with cam 4 by actuating mechanism drive between feed liquor pipe 2 and the drain pipe 7, pump line 6, feed liquor pipe 2 and drain pipe 7 are connected with briquetting 5, second flashboard 9 and first flashboard 8 with cam 4 contact respectively, feed liquor pipe 2 and pump line 6 are inserted respectively to the both ends of coupling 3, drain pipe 7 and pump line 6 are inserted respectively to another coupling 3, second flashboard 9 and first flashboard 8 do not have any between drain pipe 7 (or feed liquor pipe 6) and cam 4 to be connected, reciprocating motion in the passageway, realize reciprocating motion by the promotion of cam 4 and the resilience force of pipeline. The pressing block 5 is T-shaped, so that the pressing block 5, the first flashboard 8 and the second flashboard 9 are driven by the rotation of the cam 4 to realize the inlet and the outlet of liquid.

In this embodiment, the driving mechanism includes a motor and a gear, so that the output shaft of the motor drives the gear to drive the cam 4 to rotate, which is a common driving structure, and therefore, no schematic diagram is given.

The utility model provides a theory of operation for controlling minipump of analgesia is, drives cam 4 through actuating mechanism, as shown in fig. 1, when the first flashboard 8 of drain pipe 7 department is closed, cam 4 clockwise rotation, 5 backs of briquetting, and 6 kick-backs of pump line, and the second flashboard 9 of 2 departments of feed liquor pipe is progressively opened simultaneously, and 6 suction liquids of pump line this moment. The cam 4 continues to rotate clockwise to push the second gate plate 9, when the second gate plate 9 at the liquid inlet pipe 2 is closed, the cam 4 continues to rotate clockwise to push the pressing block 5 to compress the pump pipe 6, and simultaneously the first gate plate 8 at the liquid outlet pipe 7 is gradually opened, and at the moment, the pump pipe 6 presses out liquid, as shown in fig. 2. So circulating, the working cycle of sucking liquid and extruding liquid is completed by rotating the cam 4 by 360 degrees.

The utility model provides a be used for controlling medical product of analgesic micropump is disposable, aseptic, independent packaging, 360 rotations through cam 4, accomplish opening and closing of two flashboards respectively, promote briquetting 5 and realize the suction liquid of pump line 6 and a duty cycle of extrusion liquid, the infusion volume in the unit interval is adjusted through the duty cycle number of times of unit interval and the stroke of briquetting 5, simple structure, convenient to use, the infusion is accurate, safe and reliable.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims. Various modifications and equivalents of the invention can be made by those skilled in the art within the spirit and scope of the invention, and such modifications and equivalents should also be considered as falling within the scope of the invention.
