CN203043293U - Washing and suction device used for wound surface treatment - Google Patents

Abstract

The utility model relates to a washing and suction device used for wound surface treatment. The washing and suction device used for the wound surface treatment is characterized in that a controller is arranged in a shell body, and a wound surface negative pressure module and a wound surface liquid infusion module are connected on the controller. When the washing and suction device used for the wound surface treatment is used, an electromagnetic valve and a peristaltic pump jointly act on a wound surface, and through the timing control of the opening and the closing of the electromagnetic valve by the controller, the fact that continuity negative pressure is transformed to controllable negative pressure which is cut off at timing intervals is achieved. The working time of the peristaltic pump is controlled by the controller, the working mode that liquid is supplied continuously or liquid is supplied at intervals is achieved, an original wound surface negative pressure function is upgraded to a combined function of a wound surface washing function and a negative pressure function, the speed and the quality of wound surface negative pressure are improved, and the size of a wound surface therapeutic apparatus is reduced.

Description

A kind of flushing for Wound treating, suction device

Technical field

This utility model relates to the technical field of medical supplementary instrument, specifically a kind of flushing for Wound treating, suction device.

Background technology

Fleischmann found to place its healing rate of wound surface and quality under the negative pressure all obviously to improve in 1993, was embodied in the acceleration edema wound and disappeared, and promoted granulation tissue hyperplasia and reduce traumatic infection to take place.Nineteen ninety-five, negative pressure Wound treating technology formally was used for the treatment of clinical wound surface by U.S. food and drugs administration approved.Discovering subsequently, negative pressure Wound treating technology can be used for the reparation of acute, inferior property and chronic wound, is particularly useful for wound surface and the treatment of various chronic ulcer of clear and definite range of operation at once.Poor in medical environments such as war, natural disasters, (Hospital Multiple Casualty Incidents HMCI) in) the situation, has more special advantages easily to break out large quantities of wounded's tides.Negative pressure Wound treating technology also helps to reduce medical expense, reduces medical personnel's working strength and improves patient's compliance.But existing negative pressure Wound treating device exists machine bulky, and function singleness, the drawback that works long hours and be prone to inadequate drainage and can't realize the wound surface administration can not adapt to the requirement of modern Wound treating technical development.

Summary of the invention

The purpose of this utility model is to provide a kind of improved flushing for Wound treating, suction device, it is bulky that it can overcome in the prior art therapeutic instrument, function singleness, the some shortcomings that work long hours and be prone to inadequate drainage and can't realize the wound surface administration.

To achieve these goals, the technical solution of the utility model is: a kind of flushing for Wound treating, suction device, it mainly comprises housing, it is characterized in that: be provided with controller in the housing, be connected with Wound-surface negative pressure module and wound surface fluid injection module on the controller.

During use, electromagnetic valve of the present utility model and peristaltic pump combined effect by the switching of controller timing controlled electromagnetic valve, realize that transforming the persistence negative pressure as controlled timing is interrupted negative pressure in wound surfaceFunctionBy the working time of controller control peristaltic pump, the working method that realizes continuing feeding or be interrupted feeding, be the combination function of wound surface flushing and negative pressure function with original Wound-surface negative pressure function upgrading, improved speed and the quality of Wound-surface negative pressure, dwindled the volume of Wound treating instrument.

Description of drawings

Fig. 1 is the structural representation of this utility model one embodiment.

The specific embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

Each labelling is expressed as follows in the accompanying drawing: 1, electromagnetic valve, 2, controller, 3, peristaltic pump.

A kind of flushing for Wound treating described in the utility model, suction device, it mainly comprises housing, its difference with the prior art is: be provided with controller in the housing, be connected with Wound-surface negative pressure module and wound surface fluid injection module on the controller.Described Wound-surface negative pressure module is provided with electromagnetic valve, and described electromagnetic valve links to each other with controller.Described wound surface fluid injection module is made of peristaltic pump and reservoir, and described peristaltic pump links to each other with controller.Described controller is the accurate timing controller.

In the enforcement, this utility model transform existing persistence negative pressure source as controlled timing and is interrupted vacuum suction, can in the ranks break or the flushing of persistence wound surface or Drug therapy according to the Wound treating needs simultaneously.During use, electromagnetic valve and peristaltic pump combined effect be in wound surface, both collaborative works under the control of accurate timing controller.Wherein, peristaltic pump is worked under the control of accurate timing controller, can reach purpose from the pulsed fluid injection to wound surface that be interrupted or continue.The control work of electromagnetic valve under accurate timing control transform as with exogenous level pressure negative pressure source and to be interrupted or continuous negative pressure suction is the work purpose.

Claims (4)
