Abstract
The utility model relates to a double sleeve tube type therapeutic and preventive drainage tube for surgery, which is sheathed by two silicon rubber tubes which are provided with side holes. Substance layers, such as medical sponges, medical cotton yarn, and other substance layers which have good histocompatibility, high water absorption, or strong siphonic effects are arranged between two sleeve tubes; the external sides of the walls of the external-layer tubes are attached with a saccule; tails of the tubes are provided with an air charging port and a drainage port, and the drainage port can be connected with a negative-pressure suction device. Compared with the existing drainage tube, the double sleeve tube type therapeutic and preventive drainage tube for surgery of the utility model has safe property; double effects of the drainage of pipelines and the drainage of cigarettes can be obtained, and drainage effects are more favorable. An air bag can effectively cause the drainage tube to be fixed onto abdominal walls to prevent the drainage tube from falling. The utility model avoids conventional suture and fixation; pains of patients can be alleviated; tissue wounds can be alleviated, and operation can be simplified. The utility model can be applied to medical drainage and can be particularly used for the drainage after abdominal and thoracic surgery operations.
Description
This utility model is a kind of medical apparatus and instruments.
Medical field at home and abroad at present, especially in surgical drainage, adopt cigarette and blood plasma Tube Drain mostly,, solved the amount of drain and the problem of effect substantially though can satisfy clinical drain requirement, but alleviating aspect the patient suffering and operating aspect, also having problem anxious to be solved.
＜one〉general surgical intervention drain will be used two kinds of drains simultaneously, and a kind of is the drain of simple property silica gel tube, and a kind of is the continuous yarn drain of simple property cigarette, could thoroughly drain.＜two〉wound is bigger, and the drainage tube more than two often wound is quite big, causes more infection chance,＜three〉drainage tube of putting wants sutured in skin, and particularly postoperative is because the suture tractive causes certain misery to the patient.＜4〉cigarette drain has directly with external dressing and contacts, and long-term placement very easily causes retrograde infection.Therefore when rationally using drain to reach drainage effect, it is difficult reducing wound, reducing infection chance, alleviate the patient suffering.Acute peritonitis for example, acute critical pancreatitis, and the postoperative drainage of other operation of abdominal part.
The purpose of this utility model is to be to overcome the deficiency that above-mentioned existing drainage tube exists, and designs a kind of new drainage tube, realizes thorough drain, avoid patient's superinfection and alleviate the patient suffering, make operation easier, need not sutured, take out stitches and change dressings, reduce the chance of nosocomial infection.
Goal of the invention of the present utility model can realize in the following manner:
Medical pair of bushing type surgical intervention described in the utility model and preventative drainage tube, it comprises the silicone rubber drainage tube, the drain interface, wherein its drainage tube partly is by another root silicone rubber tube of a silicone rubber tube overcoat, inside and outside tube wall requires front end concordant, do not seal, rear end trocar sheath complete closed, inner sleeve does not seal and can connect vacuum extractor.The internal and external casing wall has side opening and straight hole, is the material layer of good high-hydroscopicity material layer of histocompatibility or strong siphonic effect between the two pipe box walls.Telescopic outside rear portion is provided with a sacculus that is surrounded on the overcoat tube wall, caudad has a gas tube to pass from the trocar sheath outer tube wall, open front is in sacculus, after be connected to the gas tube interface, interlude is close to the inwall of trocar sheath, the air-filled pore place has piston airtight, and inner sleeve drain seam can connect vacuum extractor.
This utility model is compared with the used drainage tube of present surgery, and is simple to operate, practical, safe and reliable, need not to take out stitches and changes dressings, and alleviated patient's misery, reduced the chance of nosocomial infection, and reaches the purpose of thorough drain.
Below in conjunction with drawings and Examples, this utility model done describing in further detail:
Fig. 1 is a double-sleeve type drainage tube sketch map
Fig. 2 is the inner sleeve sketch map
Fig. 3 is a double-sleeve type drainage tube tube wall profile
Fig. 4 is the sacculus profile
In the drawings
1 is trocar sheath; 2 is inner sleeve; 3 is sacculus; 4 is the gas tube interface; 5 is inner sleeve drain interface; 6 is good high-hydroscopicity material layer of histocompatibility or strong siphonic effect material layer, and 7 is gas tube, and 8 is apertura lateralis; 9 is straight hole; 10 is gas tube interface piston; 11 is inboard aperture; 12 is the trocar sheath inner tubal wall; 13 is the inner sleeve inner tubal wall; 14 is the trocar sheath outer tube wall; 15 is the inner sleeve outer tube wall.
In the present embodiment, inner sleeve 2 is placed in the trocar sheath 1, between the internal and external casing 1,2 good high-hydroscopicity material layer of histocompatibility or strong siphonic effect material layer 6, be connected in sacculus 3 before the gas tube 7, after be connected in gas tube interface 4, inner sleeve 2 is connected in inner sleeve drain interface 5, gas tube 7 interludes are close to trocar sheath inner tubal wall 12, trocar sheath 1 has side opening 8, and inner sleeve 2 has side opening 11.
Sacculus 3 is close to trocar sheath outer tube wall 14, and wide is 1～2cm, and two equal spiral punchings of silicone rubber drainage tube form, trocar sheath 1 front end 15～25cm, and 2～4cm makes a call to a hole, about 3～8 holes at interval.Inner sleeve 2 is made a call to a hole every 2～4cm, about 8～15 holes, and internal and external casing side opening 8,11 is all staggered to form, and makes a call to 3～4 straight holes 9 between interior apertura lateralis 8,11, and straight hole 9 runs through internal and external casing, is spaced apart 3～6cm.Gas tube interface piston 10 can seal gas tube 7, and the design is streamlined, and the front portion is slightly narrow, and draining hole seam 5 outlines are wide to be easy to extract and drain.
When need are inserted drainage tube, earlier from skin puncture in abdomen, this drainage tube front end is imported in the abdomen, make sacculus 3 enter the abdominal cavity by stomach wall, then from gas tube interface 4, inject water or air 5～10ml with empty needle, cover piston 10, sealing gas tube interface 4, make sacculus 3 full, stab mouthful not deviate to be as the criterion to block stomach wall, the tractive drainage tube makes and is fixed in stomach wall and does not deviate from backward, and front end is put into the position that needs drain, as long, its front end can be cut off, drain liquid will be by the side opening 8 of inner sleeve 2 and trocar sheath 1,11 straight holes 9, to external, inner sleeve afterbody drain interface 5 can connect vacuum extractor to the water sorption of medical sponge 6 with its drain.When pulling out, only need gas tube interface piston 10 is pulled out, water in it or air are pumped, pull out and get final product with the empty needle of 10～20ml.
