Abstract

The utility model relates to a thoracic-cavity drainage tube for adjusting a static line conveniently, belonging to the technical field of medical appliances, in particular to a thoracic-cavity drainage tube. The utility model aims at providing a thoracic-cavity drainage tube for adjusting the static line multiple times conveniently, so as to be convenient to change the length and position of the drainage tube in a thoracic cavity to bring the drainage into full play. In order to realize the aim, the utility model adopts the following technical scheme: one part of tube wall along the middle shaft of the tube is thinner than other parts, namely, the outer wall of the cross section of the tube is circular, the inner wall is a dome with local bulging, therefore, a thin wall area that is in parallel with the middle shaft of the tube is formed. When the tube is extruded forcefully, part of tube wall of the thin wall is depressed inwards the tube cavity, the circumference of the tube wall of the extruded part is reduced, the static line is loosened, so as to be convenient for pulling the hemostatic forceps to move to two sides; when the extruding force is removed, the depressed part restores elastically, the circumference restores to normality, and the line is tightened again to play a role of fixing.

Description

A kind of intrathoracic drain of being convenient to regulate static line

Affiliated technical field

This utility model belongs to technical field of medical instruments, designs a kind of intrathoracic drain.

Background technology

Widely used clinically at present intrathoracic drain mainly relies on the ligation of silk suture thoracic wall skin to fix for end, side-hole-type silica gel tube in use.The patient who much accepts common thoracic surgery, operation back drainage tube usually needs to adjust according to change of illness state in intrathoracic position.Need to remove the fixing of silk thread before adjusting drainage tube, need again to fix with suture needle again after adjusting to correct position.This brings misery to patient usually, and therefore patient produces the psychology of conflicting to the adjustment of necessity, influences therapeutic effect.How to address this problem and just seem extremely important.Occurring many improvement at this problem in recent years, mainly is to abandon the fixed method of suture line of skin ligation, adopts fixedly drainage tube of various air bags or holder.But these methods have been ignored two problems: the first, and silk thread affects skin no doubt can cause patient's pain, but but can the sensitivelyest remind patient timely, notes the putting position of drainage tube tractive and drainage bottle.And fixing this effect that often do not have of air bag or holder; The second, the fixed effect of air bag, holder, adhesive plaster or binder etc. is all fixing definitely firm not as thoracic wall skin, often just might change the position of drainage tube in change dressings clean wound more.And these design numerous, the complicated operation of most adnexa, and are unfavorable for manufacturing and applying.

Summary of the invention

The purpose of this utility model provides a kind of intrathoracic drain of being convenient to regulate static line, to overcome the deficiencies in the prior art.

The technical scheme that its technical problem that solves this utility model adopts is: a part of tube wall along the body longitudinal axis is thin than other parts, and promptly the tube wall periphery is round, and interior week is oval, has so just formed a tenuity parallel with the longitudinal axis.When firmly pushing body, the thin-walled portion tube wall is to the tube chamber sunken inside, and the tube wall girth of the part that is squeezed this moment reduces, and the anchoring filament line relaxation is convenient to mosquito forceps and is affected to two side shiftings; After extruding force is removed, depression position elastic recovery, girth returns to normally, and silk thread is nervous once again, the performance fixation.

Description of drawings

Fig. 2 is the drainage tube cross-sectional view

The specific embodiment

For clearly demonstrating the technical characterstic of this programme,, and in conjunction with the accompanying drawings, this programme is set forth below by a specific embodiment.

As shown in Figure 1, have thin-wall regions, thereby this a part of tube wall is subjected to external force easily and strain takes place in other position relatively along the body longitudinal axis;

As shown in Figure 2, apply certain pressure for static line place part tenuity, the stressed depression that curves inwardly of tenuity herein, other non-thin-walled portion of tube wall is drawn close to recess; Stressed place drainage tube part girth diminishes, and static line is lax, use vascular forceps just can be easily with static line two side shiftings towards periphery.When the drainage tube position adjustments when being fit to the position, remove the pressure that puts on the tube wall of static line place, the tenuity tube wall elasticity is replied, girth is got back to normal value, static line is nervous once more, the fixedly effect of drainage tube of performance again.

Claims (2)

1. an intrathoracic drain of being convenient to regulate static line comprises (1) drainage tube body, (2) stomidium, (3) side opening, (4) graduation mark and (5) tenuity, it is characterized in that: a part of tube wall along the body longitudinal axis is a tenuity.

2. intrathoracic drain according to claim 1 is characterized in that: a part of tube wall along the body longitudinal axis is thin than other parts, and the tube wall periphery is round, and interior week is oval.
