CN2834559Y - Outer sac unidirectionally adjustable double-cavity double-sac closed type drainage tube for thorax - Google Patents

Abstract

The utility model discloses an outer sac one-way adjustable type double-cavity double-sac chest closed type drainage pipe which is composed of a drainage sleeve 1, a drainage hole 2 and an inner anti-separating air sac 3, wherein an injection pipe 4 is arranged in the drainage sleeve 1. The opening edge 4a at the front end of the injection pipe 4 and the opening edge at the front end of the drainage sleeve 1 are bonded and fixed. A depth limiting air sac 5 is arranged on the outer side wall of the drainage sleeve 1 outside the inner anti-separating air sac 3. The outer side of the depth limiting air sac 5 is provided with a block ring 6. Because the depth limiting air sac at the outer side can be expanded and pressurized in a one-way mode, the pressurization degree of the drainage pipe for a cut part is adjusted properly. Because of the fixed length of an insertion section, the drainage sleeve is a flexible pipe, lung lobes can not be damage and the insertion depth is suitable. Because the injection pipe is added to the center of the drainage sleeve, the drainage can be realized, and simultaneously, the therapeutic medicine can be injected. Thus, the structure of the drainage pipe is reasonable, the drainage effect and the therapeutic effect can be raised, the operations can be simplified and the utility model has the advantages of easy operation.

Description

The two capsule closed thoracic drainage tubes of the unidirectional adjustable double-cavity of external capsule

Technical field

This utility model relates to the improvement of thoracic duction instrument, and the two capsule closed thoracic drainage tubes of the unidirectional adjustable double-cavity of specifically a kind of external capsule are applicable to the treatment of pneumothorax and breast abdomen hydrops.

Background technology

Breast lung closed drainage is effective treatment means that pneumothorax and breast abdomen hydrops generally adopt, and standard practice is to insert closed thoracic drainage tube between the midclavicular line second rib, draws intrathoracic gas or liquid, so that the lobe of the lung is opened again.The closed drainage pipe that uses at present is straight tube, be provided with three conduction holes at the top of pipe, the shortcoming of this drainage tube: the one, when drain, intrathoracic gas or liquid often overflow into subcutaneous around the drainage tube and cause that subcutaneous emphysema, severe patient can overflow to stomach wall, upper limb, cervical region, subcutaneous and cause complication such as infection and cutaneous necrosis, dyspnea; The 2nd, the drainage tube insertion depth be difficult for to be grasped, shallow then insert the lobe of the lung at interval between, lose drainage, dark drainage tube curls easily; The 3rd, due to illness the people is movable and deviate from or move easily for drainage tube.The shortcoming of for a change this straight pipe type drainage tube, what have adopts the air bag internal fixation on drainage tube, use the air bag internal fixation, can prevent that drainage tube from deviating from, but that anti-overflow effect and insertion depth are controlled effect is still undesirable; The inside and outside air bag of the employing that also has grips, though can control not outer taking off also no longer to interpolation, but because of air bag is the software state, so the clamping dynamics is wayward, also spillover can appear sometimes, simultaneously, because air bag can produce soft displacement, thus the drainage tube insertion depth still can change, in addition, the drainage tube that uses is harder plastic production at present, injures the lobe of the lung easily.

Summary of the invention

The purpose of this utility model is to provide a kind of and can not only grips by inside and outside air bag, prevent drainage tube slippage displacement, and outer air bag can unidirectionally expand, thus the two capsule closed thoracic drainage tubes of the unidirectional adjustable double-cavity of external capsule that may command clamp pressure, the generation of avoiding excessive phenomenon and insertion depth can accurately limit.

For reaching above purpose, the technical scheme that this utility model adopted is: the two capsule closed thoracic drainage tubes of the unidirectional adjustable double-cavity of this external capsule, by the drain sleeve pipe, conduction hole, interior anticreep air bag constitutes, interior anticreep air bag is bonded on the telescopic outer wall of drain, it is characterized in that in the drain sleeve pipe, establishing syringe, the front port of syringe is along fixing along bonding with the telescopic front port of drain, and sealing, drain liquid or gas can not flowed out in syringe, the dark air bag of on the telescopic lateral wall of drain in the interior anticreep air bag outside, limiting, baffle ring is established in the outside at the dark air bag of limit, force the only inwardly direction of the anticreep air bag expansion of the dark air bag of limit by baffle ring, thereby can realize the adjusting of pressure between two air bags by inflation, the drain sleeve position is fixed, also prevent skin pressure excessive or too small simultaneously.This utility model is also implemented by following measure: the length that described drain sleeve pipe inserts section is to the distance of interior anticreep air bag from the termination, its length is 3.5-5.5cm, conduction hole reticulates on the tube wall that is arranged in drain sleeve pipe insertion section, and interior anticreep air bag to the distance of limitting dark air bag is controlled in the 1.5-2.0cm scope; Baffle ring is a frustum, and the center is a circular hole, and the diameter of circular hole is consistent with the telescopic overall diameter of drain, establishes the anti-skidding stricture of vagina of pawl shape on the inwall of circular hole, and baffle ring can be promoted forward, can not fall backward; Interior anticreep air bag all is connected with corresponding inflatable ball by the small hose that is pasted on accordingly on the drain casing wall with the dark air bag of limit; Described drain sleeve pipe is a rubber hose, and to prevent to damage during insertion lungs, overall diameter is 0.7cm, and the interior diameter of syringe is 0.1-0.3cm; Interior anticreep air bag and limit the canned paragraph position syringe outer wall of dark air bag and the drain internal surface of sleeve pipe between also be provided with bracing frame, narrow to prevent from the compression of drain lacuna to be closed when interior anticreep air bag and the dark airbag aeration of limit, influence drain.When using this utility model, can make little wound, the telescopic insertion end of drain be filled in intraperitoneal with clamp, and the anticreep air bag is also filled in intraperitoneal in making, internal again anticreep airbag aeration when the drain sleeve pipe can not taken out, promotes baffle ring forward again, baffle ring is during near skin, again to limitting dark airbag aeration, when the dark air bag of limit is adjacent to skin, and aneroid gas when overflowing till, meanwhile, also on the fairlead of drain sleeve pipe rear end by hose connection storage bottle.When the needs injectable drug, the interior injectable drug of chock plug that available syringe inserts the syringe outer end gets final product, and after drain finishes, internally can extract behind the anticreep air bag deflation, and little wound can seal with adhesive bandage.

The beneficial effects of the utility model are: compare with the splanchnocoel closed drainage pipe of present use, because the dark air bag of limit in the outside can be unidirectional expansion pressurization, so easily adjust suitable to wound portion pressurization dynamics; Because insert the section fixed length, the drain sleeve pipe is a flexible pipe, thus can not injure the lobe of the lung, and insertion depth is suitable; Owing to added syringe at the telescopic center of drain, thus in drain the injectable medicine, therefore, make the drainage tube structure more be tending towards rationally can improving drainage effect and therapeutic effect, and make the simplification of performing the operation, easy operating.
