Description

One kind exempts from suture and fixes closed thoracic drainage tube

Technical field

Medical instruments field is the utility model is related to, more particularly to one kind exempts from suture and fixes closed thoracic drainage tube.

Background technology

Closed thoracic drainage tube is the most frequently used operating equipment of thoracic surgery, for the intrathoracic pneumatosis of chest postoperative drainage, Hydrops.Traditional closed thoracic drainage tube is only used for the extraction of chest intracavity liquid, causes pneumothorax, thoracic cavity to prevent drainage tube from coming off The serious complication such as hydrops is, it is necessary to which suture fixes drainage tube on skin in art.Drained when postoperative patient cough, out-of-bed activity Pipe seam line drawing skin causes patient's severe pain uncomfortable.Patient is reluctant to cough, and causes sputum and surgical wound surface oozing of blood in lung And thoracic cavity alluvial, increase postoperative lung infection risk；Patient is reluctant early ambulation, adds venous thronbosis or even lung The risk of embolism；The postoperative long-term gas leakage of some patientss or drainage flow are more, and Preserving time chest skirt, fixing line is rubbed, is broken repeatedly, Easily cause drainage tube to come off, cause pleural effusion, pneumothorax even pressure pneumothorax etc. to jeopardize the severe complication of patient vitals. Rarely has the report that the closed thoracic drainage tube for exempting from suture fixation is fixed using sacculus at present.

Utility model content

The utility model aims to provide one kind and exempts from suture fixation closed thoracic drainage tube, can be while drainage to drainage Pipe is fixed, and no longer produces the pain brought to patient of rocking due to drainage tube, easy to use, can be applicable different liquids The fixation of the drainage tube of drainage and different length.

To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：

One kind exempts from suture and fixes closed thoracic drainage tube, including drainage tube, and the outer wall in the middle part of the drainage tube is provided with solid Determine sacculus, air guide channel is provided with drainage tube wall, the interior end opening of the air guide channel connects with fixed sacculus, air guide channel Outer end opening be arranged on the outer wall of drainage tube；Also include air injection pipe, air injection pipe connects with the outer end opening of air guide channel；Institute State drainage tube wall and be provided with side opening, the side opening is between the upper and lower every being distributed on drainage tube wall and under fixation sacculus Side；The drainage tube is provided with fixed clamp, and fixed clamp is provided with external screw thread and on the upside of fixed sacculus.

One kind exempts from suture and fixes closed thoracic drainage tube, including drains outlet, air injection pipe, fix clamp, fixed sacculus, draw Flow tube, drainage entrance.Outlet, drainage tube, drainage entrance are wherein drained for the drainage to internal hydrops；Fixed clamp and drainage Manage to be fixedly connected or integrally manufactured, its surface is provided with screw thread, and geometrical clamp tubing matter needs certain hardness, avoids external solid Determine to deform when clamping when device is fixed, cause drainage tube and air guide channel obstructed.Whole drainage tube material therefor need to meet medical material Expect sterilization, thermostabilization, the requirement such as cmot, good mechanical property.

Preferably, the tube wall of the drainage tube is provided with graduation mark, and the graduation mark is located at the downside of fixed sacculus.It is fixed Sacculus is used for fixation of the drainage tube in patient's body, and fixed sacculus contacts body surface internal injury mouth skin, it is necessary near when inflating Rectangular shaped, prevent internal liquid from flowing out, the gas inside fixed sacculus taken out by syringe when drainage tube is inserted or extracted, So that fixed sacculus is close to drain pipe outer wall, convenient plug.

Preferably, the air injection pipe is located on the upside of fixed clamp.The external syringe of air injection pipe, for fixing the charge and discharge of sacculus Gas.

Preferably, in addition to it is used for the external fixator for fixing drainage tube, external fixator is adapted to fixed clamp.In vitro There are the fixation connected with external fixator a clamp, the external stability for drainage tube；External stability is added by fixed sacculus Mode whole drainage tube is completely fixed, improve the steadiness and reliability of drainage tube.

Preferably, a diameter of 5mm of the side opening, the spacing of adjacent side opening is 1cm.

Preferably, the air injection pipe is provided with switch valve.Switch valve in air injection pipe is used to consolidate when without external syringe Determine the sealing of gas in sacculus；

Preferably, the fixed balloon material is rubber or polyethylene terephthalate.

The fixed sacculus is the flexible medical macromolecular materials compared with softwood matter such as rubber, polyphenyl dioctyl phthalate ethylene glycol Ester (PET) etc., more than 3 times of drainage pipe diameter should be exceeded by fixing under the full inflated condition of sacculus, and can be big according to patient wound It is small to be adjusted, there is good expansion to reduce property.Fixed sacculus includes balloon cavity and gas port, gas port be balloon cavity and The connecting hole of air guide channel.

The drainage tube is medical macromolecular materials such as polyethylene etc., it is desirable to has certain hardness and thickness, drains the mouth of pipe Internal diameter size benefit is 14fr-36fr, to facilitate the body fluid of the different coefficients of viscosity to export.There are two paths the inside of drainage tube, i.e., Drainage lumens are used for the export of body fluid, and air guide channel is used for the inflation/deflation for fixing sacculus, and this integrated design is more conveniently drawn Flow tube into and out.

The utility model realizes drainage and the fixation of drainage tube, no longer produces because rocking for drainage tube is brought to patient Pain, it is easy to use, can be applicable different liquids drainage and different length drainage tube fixation；Fixed sacculus can be with Suitably adjusted according to wound size, facilitate the installation of different patients and position, add the applicability of the apparatus.
