Abstract

The invention discloses a drainage tube which comprises a drainage end, a hose and a connector end. Reflectible ultrasonic materials are arranged on the hose and arranged in the periphery of the hose and extends in the axial direction of the hose. The reflectible ultrasonic materials can be embedded into the wall of the hose. The spread structure of the reflectible ultrasonic materials can be in a net or point or stripe or thread shape. The reflectible ultrasonic materials are metal or fiberous protein bands. After the reflectible ultrasonic materials are arranged on the hose, positioning can be achieved through type-B ultrasound, and emulsion or a silica gel hose which are not developed under the type-B ultrasound originally can be shown clearly through the type-B ultrasound, so that the state of the drainage tube is easily observed in real time, misjudgment carried out by a medical worker on the state of the drainage tube inside a body cavity is reduced, the cost of monitoring the state of the drainage tube is lowered, and injuries caused by the process of observing the state of the drainage tube to the human body are eliminated.

Description

A kind of drainage tube

Technical field

The present invention relates to a kind of drainage tube that can observe its state under B ultrasonic, belong to medical instruments field.

Background technology

Drainage tube is at surgery medical apparatus the most more typically, and its range of application is relatively wide, is commonly used for urethral catheterization, And for will the pus of accumulation between the tissues such as wound, thoracic cavity, encephalocoele, gastrointestinal tract, biliary tract or in body cavity, Blood, liquid are directed to external, prevent postoperative infection and affect wound healing.

The material of the main part of existing drainage tube is latex material, sends into human body by paracentesis, drains disease Hydrops under reason state is chemically examined and treats.But owing to the latex part of drainage tube is the most soft material, very Easily being wound around to cause by thick fibrous bands in body cavity and kill folding, in affecting body cavity, hydrops is discharged.Work as medical care Personnel measure from human appearance when discharging without hydrops drainage tube, generally judge the emptying of endoceliac hydrops or body The drainage tube part in chamber need to go out of use because being wound around discounting.But the phenomenon sometimes discharged without hydrops in drainage tube It may also is that the change in location of drainage tube and to cause drain end not contact with hydrops caused, if this feelings Condition is mistaken in body cavity without hydrops, then will have a strong impact on the treatment effect to patient, even results in medical treatment thing Therefore, if this situation is mistaken for drainage tube and need to go out of use, then will result in waste greatly.

Existing drainage tube is inserted endoceliac part and is relied primarily on CT location, but CT is costly, increases The financial burden of patient, and human body also will work the mischief by radiation produced by CT.

Summary of the invention

The problems referred to above existed for drainage tube in prior art, the present invention provides one can observe under B ultrasonic The drainage tube of its state.

Technical scheme is as follows:

A kind of drainage tube, including drain end, flexible pipe and tip side, described flexible pipe is provided with can reflectance ultrasound Material, described the material of reflectance ultrasound can prolong the circumferentially disposed of flexible pipe, and prolongs the axially extending of flexible pipe.At flexible pipe Upper setting can realize location by B ultrasonic after the material of reflectance ultrasound, make originally not develop under B ultrasonic Latex or the state of silica gel hose clearly can be displayed by B ultrasonic, thus realize drainage tube Simple, the real-time monitored of state, decreases medical personnel's erroneous judgement to the state of chamber drainage tube, reduces The cost of monitoring drainage tube state, eliminates the injury that human body is caused by the process of observation drainage tube state.

As the further improvement of invention, described can the material of reflectance ultrasound be embedded in inside hose wall.Can reflect Ultrasonic material is a lot, and some material may be not suitable for and direct body contact, such as metal material.Therefore, To be able to the material of reflectance ultrasound be embedded in inside hose wall, neither affect B ultrasonic development, be avoided that again these materials The material injury to human body.

As the further improvement of invention, described the material of reflectance ultrasound can spread all over whole flexible pipe, it spreads all over structure For netted and/or point-like and/or striated and/or screw-like.Netted, point-like, striated, screw-like are more normal The uniform arrangement mode seen, can make the various piece of flexible pipe be clearly shown out.

As the further improvement of invention, described can the material of reflectance ultrasound be metal and/or fibrin bar rope.

Beneficial effects of the present invention is as follows:

The drainage tube of the present invention by spread all on flexible pipe arrange can the material of reflectance ultrasound, make the state energy of flexible pipe Enough clearly displayed by B ultrasonic, it is achieved thereby that the real-time monitored to drainage tube state, simple to operate, Nonhazardous, decreases medical personnel's erroneous judgement to the state of chamber drainage tube, reduces because of medical personnel by mistake Sentence and discarded drainage tube or the cost of CT monitoring, eliminate what human body was caused by the process of observation drainage tube state Injury.
