Description
Technical Field
The invention relates to a medical device for treating postoperative complications, in particular to a removable drainage irrigation sleeve device.
Background
Fistula formation is a common complication after gastrointestinal surgery, and is very likely to be accompanied by infection. If an infection occurs, the hospitalization time of the patient is prolonged, and a series of serious subsequent complications endangering life are caused, so that the life health and the family economy of the patient are greatly influenced. Fistula formation is unpredictable and often has a close relationship with uncontrollable factors such as patient constitution, local blood supply and the surrounding environment of the operating field.
The drainage tube is a tube for draining secretion, blood and pus in the fistula to the outside, and the purpose of drainage is to reduce the probability of postoperative inflammation. For some operations with or possible to be polluted, such as gastrointestinal tract operations, the drainage tube can be put into a human body in advance to play a role in prevention. One end of the drainage tube is inserted into the wound surface of the fistula, the other end of the drainage tube is connected with external equipment, and secretions, blood and pus in the fistula are drained outwards in a negative pressure mode, a gravity mode and the like. Advanced placement of the drainage tube can cause medical collateral damage to patients who do not develop fistulae or abscesses.
Drainage tubes are likely to become clogged during drainage due to the sticky pus or blood stasis. The drainage tube can be folded and deformed due to factors such as suction force in the drainage process, so that drainage is not smooth. When the drainage tube is blocked, the existing method is to pull out the drainage tube and then reinsert a new drainage tube. However, the drainage tube is fixed on the skin of a patient through a suture in advance, if the drainage tube is to be pulled out, the suture for fixing the drainage tube is firstly cut off, then the patient is instructed to inhale deeply and then hold breath, and the drainage tube is pulled out when the patient holds breath. A suture is also required to secure the new drain tube to the patient's skin after placement of the new drain tube. It can be seen that the re-placement of a new drainage tube increases the pain of the patient in treatment and increases the risk of secondary infection
Therefore, how to avoid the medical auxiliary injury caused by the drainage tube and how to avoid causing pain to the patient when a new drainage tube is placed is a critical problem to be solved urgently by those skilled in the art.

Detailed Description
The invention discloses a removable drainage irrigation sleeve device, which can avoid medical auxiliary injury caused by a drainage tube and can avoid causing pain to a patient when a new drainage tube is placed.
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Reference herein to "front end" refers to the end proximal to the patient, and reference to "back end" refers to the end distal to the patient.
Please refer to fig. 1-5.
The invention discloses a removable drainage flushing sleeve device which comprises a drainage tube 9, a flushing tube 8, an inner sleeve 12 and an outer sleeve 11. The drainage tube 9 and the flushing tube 8 can be inserted into the inner sleeve 12. After the drainage tube 9 and the flushing tube 8 are inserted into the inner sleeve 12, the drainage tube 9 and the flushing tube 8 are fixed relative to the inner sleeve 12, so that the drainage tube 9, the flushing tube 8 and the inner sleeve 12 are combined into an inner sleeve 12 combined tube. The drainage port of the drainage tube 9 and the flushing port of the flushing tube 8 extend from the front end of the inner tube 12, so that the drainage port and the flushing port can operate smoothly.
The inner sleeve 12 is insertable into the outer sleeve 11, and the inner sleeve 12 is axially movable relative to the outer sleeve 11 under the influence of an external force. Both ends of the outer sleeve 11 are openings, the inner sleeve 12 is inserted from the rear end opening of the outer sleeve 11, and the drainage operation port of the drainage tube 9 and the flushing operation port of the flushing tube 8 extend from the front end opening of the outer sleeve 11. Also, the outer cannula 11 may be placed into the patient.
In performing a contaminated operation such as a gastrointestinal tract operation, the outer sleeve 11 is placed in the patient. If a fistula is formed in the patient's body, an inner cannula 12 fitted with a drainage tube 9 and an irrigation tube 8 is inserted into an outer cannula 11, thereby effecting the placement of the drainage tube 9 and irrigation tube 8. Compared with the technical scheme that the drainage tube 9 is placed in the patient in advance in the prior art, the drainage tube 9 cannot be placed in advance, and the drainage tube 9 can be placed only when the fistula appears in the patient, so that medical auxiliary injury is effectively avoided.
The drainage tube 9 is likely to be clogged during drainage due to the viscous pus or blood. The drainage tube 9 can be folded and deformed due to factors such as suction force in the drainage process, so that drainage is not smooth. If a problem of poor drainage occurs, only the inner sleeve 12 needs to be pulled out, after which a new drainage tube 9 is fitted into the inner sleeve 12, and finally the inner sleeve 12 is reinserted into the outer sleeve 11. Compared with the technical scheme that the suture for fixing the drainage tube 9 is needed to be cut off firstly, the new drainage tube 9 is placed, and then the drainage tube 9 is fixed on the skin of a patient through the suture, the technical scheme that the suture is not needed to be cut off, and only the inner sleeve 12 is needed to be pulled out or inserted in the invention can obviously relieve the pain of the patient, and the efficiency of placing the new drainage tube 9 can be obviously improved, so that the risk of infection of the patient can be reduced.
It should be noted that, if the drainage tube 9 is fixedly connected with the inner sleeve 12 through an interference fit manner, when the drainage tube 9 is blocked, the drainage tube 9 can be pulled out only, and after the new drainage tube 9 is replaced, the new drainage tube 9 is assembled into the inner sleeve 12, so that the placement of the new drainage tube 9 can be realized.
It should also be noted that, for fistulae with larger or elongated lacuna, the specific depth of the fistula is unknown. After the drainage tube 9 and the flushing tube 8 are placed, flushing and drainage are often not complete due to an insufficient placement depth. In this case, the depth of insertion of the drainage tube 9 and the flushing tube 8 should be increased. In the prior art, if the depth of placement of the drainage tube 9 and the irrigation tube 8 is increased, the suture for fixing the irrigation tube 8 and the drainage tube 9 is first released, and after the suture is put in place, the irrigation tube 8 and the drainage tube 9 need to be fixed to the skin of the patient again through the suture. The operation mode not only increases the pain of the patient, but also increases the risk of infection of the patient. In the present invention, however, if the depth of insertion of the drainage tube 9 and the irrigation tube 8 is to be changed, it is only necessary to apply an external force to the inner sleeve 12 so that the inner sleeve 12 moves in the axial direction of the outer sleeve 11. If the depth of insertion of the drainage tube 9 and the flushing tube 8 is to be increased, the inner sleeve 12 is driven to move towards the front end of the outer sleeve 11, and if the depth of insertion of the drainage tube 9 and the flushing tube 8 is to be reduced, the inner sleeve 12 is driven to move towards the rear end of the outer sleeve 11. Since the drainage tube 9 and the flushing tube 8 are fixed relative to the inner tube 12, the movement amount of the inner tube 12 is the movement amount of the drainage tube 9 and the flushing tube 8.
In addition, since the inner sleeve 12 is placed in the body of the patient, the inner sleeve 12 forms a certain attractive force to surrounding tissues, the fistula tissues are continuously attached due to the attractive force under the condition of full flushing, the filling of granulation tissues and fibrous tissues in the fistula is promoted, and the healing process is promoted. At the same time, the inner cannula 12 is gradually pulled out to continuously repair and heal the fistula tissue, thereby greatly shortening the hospitalization time of the patient.
In the invention, the material of the outer sleeve 11 is preferably silica gel, namely the outer sleeve 11 is a silica gel tube. The inner tube 12 is preferably made of silica gel, and the inner tube 12 is also a silica gel tube. And the present invention defines an outer diameter of the inner sleeve 12 that is 0.1mm smaller than an inner diameter of the outer sleeve 11. After the inner sleeve 12 is inserted into the outer sleeve 11, the inner sleeve 12 is fixed relative to the outer sleeve 11 when no external force is applied, and the inner sleeve 12 is almost in sealing engagement with the outer sleeve 11, or the gap between the inner sleeve 12 and the outer sleeve 11 is very small. If it is necessary to adjust the replacement of the inner sleeve 12 or to adjust the insertion depth of the drainage tube 9 and the flushing tube 8, an external force may be applied to the inner sleeve 12, so that the inner sleeve 12 moves axially in the outer sleeve 11.
In a specific embodiment of the invention, the outer diameter of the inner sleeve 12 is designed to be 9.5mm, the inner diameter is designed to be 8mm, the outer diameter of the outer sleeve 11 is designed to be 11.5mm, and the inner diameter is designed to be 9.6mm.
