A dialysis hole (9) is arranged on a tube head (8) at the lower part of the tube, a sleeve (4) is arranged at the upper part of the tube head, an inner sleeve connecting clamp (10) and an outer sleeve connecting clamp (10) are arranged at the port of the outer sleeve (3), and the inner sleeve (2) and the outer sleeve (3) are connected together; the port of the inner sleeve (2) is exposed, and a cap (1) is arranged on the port. Can prevent the dialysis tube from sliding, slipping and blocking, and has good dialysis effect.
Description
The present invention relates to the instrument field of medium being imported in the body or being taken out medium in the body of medical science, relate to a kind of fixer for peritoneal dialysis tube particularly.
In the dialysis treatment of renal failure, adopt too grace koff (Fenckhoff) Dialysis tubing usually, (UI-91371844 clinically; AU-Colombl; A; Ayer G; Burrl G; TI-The stralght Tenckhoff Catheter; LA-Eng; SO-Contrlb Nephrol 1991; 89:31-4) its structure is to be the single lumen catheter that raw material is made by silicone rubber, can be divided into straight, crooked, single deck tape-recorder husband (oversleeve), two Krafts and no Kraft.No Kraft and single deck tape-recorder husband Dialysis tubing are used for the acute renal failure treatment, are beneficial to non-operation tube pulling when stopping peritoneal dialysis catheter; The more preceding two kinds of pipe stationarity of two Kraft Dialysis tubings are good, are beneficial to the peritoneal dialysis all the year round of chronic renal failure.But the shortcoming that exists is to put in 3-4 weeks of pipe, can not grow in the Kraft (oversleeve) because of tissue, and Dialysis tubing easily slides, slippage or around pipe discharge and causing from the tunnel inflammation, increase the incidence rate of peritonitis, force to stop dialysis treatment clinically or change hemodialysis treatment etc.; Need put pipe again after its pipe slippage, increase misery etc. to patient.
For solving the slippage problem of peritoneal dialysis catheter, once released Llfe cath Dialysis tubing in the sample of U.S. Qulnton instrument company in 1988, its structure is made up of single chamber silicone rubber tube and a porous disc.In silicone rubber tube and disc centre junction with apart from about 10 centimeters of disk one terylene Kraft (oversleeve) is arranged respectively.When putting pipe, owing to its disk is attached on the stomach wall, so this pipe has solved Dialysis tubing slip, slippage problem preferably.But because disk is at abdominal cavity extreme lower position (in bladder rectum or the uterus rectum lacuna), so its existence is unfavorable for appearing of abdominal dialysis liquid, and the shortcoming that can't promote clinically, use.
The objective of the invention is to overcome the shortcoming of above-mentioned too grace koff (Fenckhoff) Dialysis tubing and Llfe Cath Dialysis tubing, a kind of fixer for peritoneal dialysis tube is provided, it can prevent effectively that dialysis from sliding at intraperitoneal, slippage, complication such as the tunnel inflammation that discharge causes around preventing from again to manage certainly, peritonitis, reduce patient's misery, disease is treated timely and effectively.
Task of the present invention is to realize by the technical scheme that is provided with a fixture on the tube wall of the trocar sheath of two bushing type peritoneal dialysis catheters.Its major technique feature is on the tube wall of the trocar sheath 3 of its Dialysis tubing, and promptly the position of abdominal cavity section and hypodermic tunnel intersection is provided with a fixture, and it comprises peritoneum wild card 5, interior card 6 and purse wire ligation place 7 between the two.Having dialysis hole 9 on the tube wall of the tube head 8 of its underpart communicates with its tube chamber; Its top is provided with oversleeve 4.Be provided with an inside and outside sleeve pipe in the port of trocar sheath 3 and be connected card 10, general, internal and external casing 2,3 connect; Outside the port of inner sleeve 2 is exposed to, which is provided with medicated cap 1, seal its port.
Its technical characterictic is the truncated cone-shaped that its peritoneum wild card 5 is a hollow, and intraperitoneal card 6 is inverted hollow round table shapes, and the two all is sleeved on the trocar sheath 3 tube walls outside, and the distance of the two (being the continuous bundle place 7 of purse wire) is 2 millimeters.Its inner sleeve 2 matches to merge with trocar sheath 3 and is set in the trocar sheath 3, and leaves certain interval between the two, have on the tube head of inner sleeve 2, the tube wall with the tube head of trocar sheath 3, tube wall on corresponding dialysis hole 9.Its oversleeve 4, peritoneum wild card 5 are made with hair matter terylene; Intraperitoneal card 6, inside and outside sleeve pipe 2,3, medicated cap 1 and inside and outside sleeve pipe are connected card 10 usefulness medical grade silicon rubbers and make.
The present invention is because of the abdominal cavity section and the hypodermic tunnel intersection that this fixture are located on the peritoneal dialysis catheter trocar sheath tube wall, its peritoneum wild card 5, interior card 6 are truncated cone-shaped and inverted truncated cone-shaped and the two and are provided with purse wire ligation place 7, so it can fasten peritoneum on therebetween the tube wall with purse wire, its tube wall is fixed, do not slide, not slippage, prevent also simultaneously that Intraabdominal liquid is excessive along pipe on every side, avoided the generation of tunnel inflammation, peritonitis, overcome because of its pipe slides, slippage need be put the misery that pipe brings to patient again; Because its tube head can go deep into the extreme lower position (in bladder rectum or the uterus rectum lacuna) in abdominal cavity, penetrate or separate out so it is beneficial to peritoneal dialysis solution simultaneously, dialysis-effect is good, is beneficial to the alleviation and the rehabilitation of patient's state of an illness; In addition, owing to adopt two telescopic structural designs, so in use can prevent the obstruction of blood clot, protein to its dialysis hole, its inner sleeve can take out cleaning at any time and remove the interior tamper of its pipe, to guarantee the unimpeded of hole of dialysing, overcome to block to need Dialysis tubing transferred to and put pipe again and cause suffering to patient because of the blocked thing in dialysis hole of its pipe; Owing to its structural design novelty, reasonable, simple in structure, easy to operate, can and have various Dialysis tubings now and be used, besides so it is suitable for applying on the hospital clinicals at different levels.
Concrete structure of the present invention is provided by following embodiment and accompanying drawing.
Fig. 1 is the structural front view according to the fixer for peritoneal dialysis tube of the present invention's proposition.
Fig. 2 is that the A of Fig. 1 is to view.
Describe the details of the fixer for peritoneal dialysis tube that proposes according to the present invention in detail below in conjunction with accompanying drawing 1, Fig. 2.
This device comprises by trocar sheath 3, inner sleeve 2, hair matter terylene oversleeve 4, peritoneum wild card 5, in card 6 and therebetween purse wire ligation place 7, the inside and outside sleeve pipe of dialysis hole 9 of being opened on tube head 8, the tube wall and trocar sheath port is connected card 10, closing cover 1 constitutes set intermittence on inner sleeve 2 ports.This fixture is located on the tube wall of trocar sheath 3 in the present embodiment, and peritoneum wild card 5 is located at the bottom of hypodermic tunnel, and intraperitoneal card 6 is located at the top of abdominal cavity section, and the two is purse wire ligation place 7, and peritoneum can fasten on it with purse wire and (not draw among the figure).Peritoneum wild card 5 is the truncated cone-shaped of hollow, and intraperitoneal card 6 is is inverted hollow round table shape, and the two is set on the tube wall of trocar sheath 3.The distance of the two (purse wire ligation place 7) is 2 millimeters therebetween.Inner sleeve 2 matches to merge with trocar sheath 3 and is set in it, its two leave certain interval.Have on the inner sleeve 2 with trocar sheath 3 on corresponding dialysis hole 9, communicate with its tube chamber respectively; Outside its port is exposed to, which is provided with intermittently closing cover 1.Inside and outside sleeve pipe in trocar sheath 3 ports is connected card 10 inside and outside sleeve pipe 2,3 is connected.This device is applied widely, can be used with existing various peritoneal dialysis catheters, can reduce the generation of complication of peritoneal dialysis, has clinical value widely.
