Description

Medical hollow cigarette drain pipe

This utility model belongs to the clinical treatment device, mainly proposes a kind of hollow cigarette drain pipe, is applicable to the drainage of abdomen in the abdominal surgery.

The drainage system of placing in the abdominal surgery has two-chamber bushing type drainage tube and common cigarette drain pipe at present, the two-chamber drainage tube can carry out drain and flushing to the abdominal cavity, but easily lost drainage after placing by the obstruction of abdominal tissue such as omentum majus, the common cigarette drain of using always in now clinical, be to make with roller periphery lining latex skin graft, placing the rotten tissue of back clot or solid can not draw, and use this drainage tube drain, substance moisture spreads on otch and easily causes infection of incisional wound, and simple silica gel tube drain is also easily stopped up by abdominal tissue such as omentum majuss.

Goal of the invention of the present utility model promptly is this, and it is smooth and easy and be difficult for blockedly to make the drainage tube of proposition have in the abdomen drain, utilizes infiltration in addition and breathes the effect that principle reaches constant drainage, has the characteristics of structural design advantages of simple simultaneously.

This utility model takes following approach to reach goal of the invention: it has the trocar sheath that the bottom sets the interior pipe of central authorities of a plurality of side openings and sets side opening equally, apply between pipe and the trocar sheath in the central authorities and put gauze or disinfection sponge body, promptly central outer wall of inner tube garden week applies and puts gauze or disinfection sponge body; Drainage tube trocar sheath epimere footpath is bigger, it is positioned at when using and has the effect of the drain of storage liquid outside the abdominal cavity, extrude drain liquid and can keep its oozing property of suction drainage, hypomere has 3-5 side opening for abdominal cavity inner segment front end again in the drainage tube trocar sheath, have gauze or spongy body to rise to filter in itself and the central authorities between the side opening of pipe and prevent ponding, the front end mouth of pipe of drainage tube can drain solid matter.

Drainage of abdomen should satisfy the requirement of following several respects through summary in clinical:

A, drainage tube softness are flexible.

B, inner chamber do not subside.

C, X line or B ultrasonic show.

D, intracavity external friction coefficient are little, and drain is unobstructed, and rotten tissue such as clot can be discharged.

Can prevent when e, enclosed vacuum suction that tissue is inhaled in the pore, can prevent retrograde infection.

F, do not influence patient's ambulation, and be convertible into the drain of dell formula.

The hollow cigarette drain pipe that the utility model proposes satisfies above-mentioned condition substantially, it has following characteristics: (1) this drainage tube belongs to closed drainage substantially, is nested with silica gel sheath at the epimere mouth of pipe during use, changes silica gel sheath when changing dressings, temporary transient open, the abdominal cavity infection chance is few.(2) this drainage tube can avoid side opening to stop up when the suction flushing, and this design simultaneously helps reducing the abdominal cavity negative pressure, is easy to drain and flows out.(3) regularly squeeze the epimere of drainage tube during the drain, drain liquid is clamp-oned in the cover, can guarantee the constant drainage effect of drainage tube like this.(4) use this utility model drain to concentrate in the cover and not soak has reduced the infection of incisional wound chance on otch.(5) clot or rotten tissue can be through the top of drainage tube mouth flushing sucking-offs, when pus dense when thick, take out most intraluminal fluid earlier, inject raridas liquid through central canal, or the X Chymotrypsin is to reduce its viscosity, as treat and need be able to inject the metronidazole injection and celebrate big saline etc. to the abdominal cavity, in order to the control abdominal cavity infection.(6) this drainage tube is made center bearing bracket by latex tubing, inner chamber do not subside and lance soft flexible, sebific duct is inside and outside and cigarette skin graft aquagel membrane area is big, resistance is little, can sharp drain.(7) placing this drainage tube does not influence patient's ambulation, can promote restoration of gastrointestinal function.

In a word, this utility model structural design drainage effect is good, and patients ' recovery is fast, and simple in structure, and is easy to operate.

Accompanying drawing 1 is this utility model structural representation.

In conjunction with the accompanying drawings this utility model structure is further specified:

As shown in drawings: pipe 1 bottom sets a plurality of side openings 2 in the central authorities of the present utility model, its outer wall garden week is equipped with gauze 3, it also can be the disinfection sponge body, be coated with skin graft 4 at gauze or spongy body as trocar sheath, its downside has set side opening 2 equally, and trocar sheath 4 epimeres 5 are positioned at the outside, abdominal cavity when being drain epimere diameter is bigger, is beneficial to store institute's draining fluids, can be nested with the liquid storage cover in the drainage tube upper end in use, the liquid storage cover can be the shell-like thing that general silica gel material is made.

Claims

1, a kind of medical hollow cigarette drain pipe, feature of the present utility model is: it has the bottom and sets the trocar sheath (4) of managing (1) and setting side opening (2) equally in the central authorities of a plurality of side openings (2), apply between pipe (1) and the trocar sheath (4) in the central authorities and be equipped with gauze, disinfection sponge body (3), promptly pipe (1) outer wall garden week coats gauze, disinfection sponge body (3) in the central authorities, and trocar sheath (4) epimere (5) is positioned at the epimere section diameter of outside, abdominal cavity greater than hypomere when being drain.
