Description

Disposable through flushing drainage catheter

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a disposable link up and wash drainage catheter.

Background

With the development of modern industry and transportation industry, the occurrence of high-energy violent injury of the body is on the rise, wherein the complex limb damage combining the conditions of soft tissue defect, bone exposure and the like is more and more common in clinic. Severe body destruction and injury are mostly accompanied by the defect of wound soft tissue, which leads to the exposure of tendon and bone of patients, and causes the infection morbidity and the necrosis rate of the injured part to be increased.

And the boundary between most wound surfaces and normal tissues is fuzzy, the effective treatment in the phase I cannot be realized, the wound surfaces of patients need to recover and regenerate for a certain time after the surgical treatment, and the wound surfaces cannot be closed immediately in this period, so that a large amount of exudate accumulation occurs on the wound surfaces of the patients, the prognosis effect of the patients cannot be ensured, and the decline of the prognosis effect of the patients is easily caused.

In order to reduce the affected degree of the wound surface of a patient clinically, the patient needs to be drained in addition to the prevention of infection symptoms of the patient by utilizing drug treatment. The correct drainage can eliminate the hematocele in the wound surface, necrotic tissues and foreign matters, eliminate dead cavities, improve local blood circulation, avoid wound surface soft tissue infection and promote wound healing.

The current clinical common drainage devices comprise one-way drainage and one-way negative pressure drainage, but poor drainage and retrograde infection are easy to occur.

Disclosure of Invention

The utility model aims to solve the problem of providing a disposable through flushing drainage catheter, which is particularly suitable for a user to fill sterile physiological saline to help the patient to improve the wound surface and wound recovery effect by utilizing the through flushing drainage catheter; promoting the exchange of substances inside and outside the drainage tube in the body.

In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a disposable link up washes drainage catheter, including the flushing pipe, be provided with the portion of washing on the flushing pipe, the position evenly distributed that just is located the portion of washing on the flushing pipe is provided with the flushing hole, flushing pipe one end intercommunication is provided with a thin spiral joint, installs a rotary joint sheath on the thin spiral joint, flushing pipe one end intercommunication is provided with a check valve, the check valve free end intercommunication is provided with a waste liquid pipe, the free end of waste liquid pipe is provided with a thin spiral joint, install a rotary joint sheath on this thin spiral joint. The check valve comprises a connecting pipe, a first inserting block, a second inserting block and a valve body, wherein one end of the first inserting block and one end of the second inserting block are respectively provided with the connecting pipe, the first inserting block is communicated with the waste liquid pipe through the connecting pipe, the second inserting block is communicated with the flushing pipe through the connecting pipe, the first inserting block is connected with the second inserting block in an inserting mode, the valve body is arranged in a cavity formed by the first inserting block and the second inserting block, the valve body is of a one-way check valve body structure, and the flowing direction of the valve body is from the second inserting block to the direction of the first inserting block. A user firstly buries the flushing part on the flushing pipe into the wound of a patient, at the moment, waste liquid flows into the flushing pipe through the flushing hole, and then the waste liquid passes through the check valve and is discharged through the waste liquid pipe; then, the user adds normal saline, is connected the thin screwed joint and the normal saline device of flushing pipe one side, and normal saline flows into in the flushing pipe through thin screwed joint, and then flows through the washing portion, realizes the liquid exchange through the flushing hole, and the waste liquid loops through check valve and waste liquid pipe discharge, makes the waste liquid can not take place the backward flow owing to the effect that has the check valve this moment, avoids causing the secondary infection.

The utility model has the advantages and positive effects that: by adopting the technical scheme, the utility model can take away the pus and infectious bacteria of the patient in the flushing process, and according to clinical observation, the reverse infection of the wound and the infection of local focus can not be caused, and the control on the infection has good effect; just the utility model relates to an upgrade and the replenishment of current clinical negative pressure drainage device all can use in numerous medical fields such as open fracture, joint replacement, diabetes are sufficient, skin defect, have wide market prospect and clinical value to will drive the research and development iteration of relevant product simultaneously, the upgrading of medical plastics trade promotes to fill drainage technique and popularize fast.
