Abstract
The utility model discloses a peritoneal dialysis catheter which comprises a catheter body, a sacculus, a sacculus outer shell, a stainless steel supporting rack and a stainless steel sheet. The catheter body is connected with the sacculus outer shell, the sacculus is installed in the sacculus outer shell, the catheter body is communicated with the sacculus, the stainless steel supporting rack used for supporting the sacculus is installed inside the sacculus, the stainless steel sheet used for preventing a needle from penetrating is installed at the bottom of the sacculus, the catheter body is provided with two convex blocks, the distance between the two convex blocks is 0.4cm, the two convex blocks are placed inside and outside the abdominal cavity of a small mouse respectively, and the catheter body and the sacculus are both made of silicon resin. When the peritoneal dialysis catheter is used, the sacculus and the sacculus outer shell are hidden below the skin of the back of the small mouse innovatively, the catheter body connected with the sacculus and the sacculus outer shell are arranged below the skin, a small incision is cut in the abdomen, the catheter body is inserted in the abdominal cavity, and on the premise of not affecting a normal experiment, wound to the peritoneum of the small mouse can be reduced, and the death rate of the small mouse is reduced.
Description
Technical field
This utility model relates to a kind of laboratory installation, is specifically related to a kind of peritoneal dialysis catheters.
Background technology
Peritoneal dialysis is to utilize peritoneum to be dialyzer, inject dialysis solution to intraperitoneal, poor by the solute concentration difference in blood plasma in the blood capillary of both sides and Intraabdominal dialysis solution and infiltration, the excess moisture disperse of the metabolic waste in blood plasma and retention and be penetrated into the abdominal cavity, and excrete with old dialysis solution, simultaneously by replenishing necessary material in peritoneal dialysis liquid in blood.Pour into fresh dialysis fluid by continuous repetition to intraperitoneal, dialysis solution retains certain hour at intraperitoneal, discharges the dialysis solution that exchanged, and can reach the therapeutic purposes of removing toxin, dehydration, correction acidosis and electrolyte disturbance.Be commonly used to treat acute and chronic renal failure, also can be used to the salvage drug alimentary toxicosis.
From the national conditions of China, abdomen quite is fit to the need of patient thoroughly, is conducive to the protection of residual renal function.Especially rising at vast different medical unit, be the Kidney Disease pattern in whole latter stage that China widelys popularize at present.But, in the peritoneal dialysis process, complication such as infection, malnutrition, Lipoprotein Disorders, peritoneal membrane function forfeiture can appear, and the peritoneal dialysis liquid of heterogeneity can cause in various degree damage to peritoneum simultaneously.Peritoneal dialysis model with usual use is based on the laboratory animals such as mice or rat, and is saturating with lumbar injection simulation every day abdomen.But the abdominal cavity direct injection is traumatic large to peritoneum, easily damages little blood vessel, improves mortality of animals etc.
The utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can reduces mortality of animals and wound, and does not affect the peritoneal dialysis catheters of experiment.
This utility model is achieved through the following technical solutions: a kind of peritoneal dialysis catheters comprises conduit, sacculus, sacculus shell, rustless steel bracing frame and stainless steel substrates, described conduit is connected with the sacculus shell, described sacculus is arranged in the sacculus shell, described conduit communicates with sacculus, described rustless steel bracing frame for supporting balloon is arranged on sacculus inside, and is described be used to preventing that syringe needle from pricking the stainless steel substrates of wearing and being arranged on the sacculus bottom.
Further, be provided with two projections on described conduit, the distance between described two projections is 0.4cm, and described two projections are placed in inside and outside mouse peritoneal respectively.
Further, described conduit and sacculus are the employing silicone material.
Further, described catheter tip is provided with aperture, when conduit mouth is stopped up, and can also be by aperture to injecting in abdomen.
The beneficial effects of the utility model are: when using this utility model, sacculus and sacculus shell are imbedded in mouse back innovatively subcutaneous, the conduit that is attached thereto is in subcutaneous traveling, make a little otch at abdominal part, conduit is inserted the abdominal cavity, under the prerequisite that does not affect normal experiment, can reduce the wound to mouse peritoneum, reduce the mortality rate of mice.
Description of drawings
In order to be easy to explanation, this utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of a kind of peritoneal dialysis catheters of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of peritoneal dialysis catheters of the present utility model, comprise conduit 3, sacculus 6, sacculus shell 5, rustless steel bracing frame 4 and stainless steel substrates 7, described conduit 3 is connected with sacculus shell 5, described sacculus 6 is arranged in sacculus shell 5, described conduit 3 communicates with sacculus 6, and described rustless steel bracing frame 4 for supporting balloon 5 is arranged on sacculus 6 inside, and is described be used to preventing that syringe needle from pricking the stainless steel substrates 7 of wearing and being arranged on sacculus 6 bottoms.
A kind of optimal way of the present utility model is provided with two projections 2 on described conduit, the distance that described two projections are 2 is 0.4cm, and described two projections 2 are placed in inside and outside mouse peritoneal respectively.
A kind of optimal way of the present utility model, described conduit 3 and sacculus 6 are the employing silicone material.
A kind of optimal way of the present utility model, described conduit 3 ends are provided with aperture 1, when 3 mouthfuls, conduit stops up, can also be by injecting in 1 pair of abdomen of aperture.
The beneficial effects of the utility model are: when using this utility model, sacculus and sacculus shell are imbedded in mouse back innovatively subcutaneous, the conduit that is attached thereto is in subcutaneous traveling, make a little otch at abdominal part, conduit is inserted the abdominal cavity, under the prerequisite that does not affect normal experiment, can reduce the wound to mouse peritoneum, reduce the mortality rate of mice.
The above be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work is within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (4)
