Description
Technical field
The invention belongs to hemodialysis technology fields, and in particular to a kind of peritoneum dialysis catheter guiding device.
Background technique
Peritoneal dialysis is a kind of dialysis using the peritonaeum of human body itself as dialysis membrane.By pouring into the saturating of abdominal cavity
Analysis liquid in the capillary of the peritonaeum other side plasma composition progress solute and moisture exchange, remove the metabolism of internal retention
Product and excessive moisture, while substance necessary to body is supplemented by dialyzate.By constantly updating peritoneal dialysis liquid, reach
The purpose of kidney substitution or supportive treatment.When peritoneal dialysis treatment, by peritoneal dialysis catheters by peritoneal dialysis solution fill into
Abdominal cavity.The side of intraperitoneal peritonaeum is the blood containing waste and excessive moisture in peritonaeum capillary, and the other side is that peritonaeum is saturating
Liquid is analysed, the waste and extra moisture in blood enter in peritoneal dialysis liquid through peritonaeum.After a period of time, containing waste and extra
The peritoneal dialysis solution of moisture is released in abdominal cavity, then fills into new peritoneal dialysis solution, is constantly recycled in this way.
Now, before carrying out peritoneal dialysis to patient, peritoneum dialysis catheter can only be inserted into abdominal cavity by medical staff by rule of thumb, but
It is to be influenced since the figure posture of different patients is different, or by the past abdominal operation history, the internal structure in abdominal cavity can also deposit
In certain difference.Therefore, the mode of medical staff's blindmate peritoneum dialysis catheter is likely to occur the feelings of catheter position inaccuracy at present
Condition leads to peritoneal dialysis solution inadequate drainage, and dialysis-effect is not good enough, visceral organ injury etc..Solving problem above becomes the task of top priority.
Summary of the invention
For solve current medical staff can only blindmate peritoneum dialysis catheter, there are peritoneal dialysis place tube located inaccuracy and damages
The technical issues of internal organs hidden danger, the present invention provide a kind of peritoneum dialysis catheter guiding device.
To achieve the above object, technical solution of the present invention is as follows:
A kind of peritoneum dialysis catheter guiding device, the guiding device shell including elongated structure, the guiding device shell are thin-walled
Structure, and have through the inner passage at its both ends, be characterized by: the partial sidewall of the guiding device shell has been recessed
The saturating pipe limiting slot of the abdomen extended along its length is respectively provided with the saturating pipe limit of one piece of abdomen in the two sides of the saturating pipe limiting slot of the abdomen
Plate, the saturating pipe limit plate of two pieces of abdomens is staggered along the length direction of guiding device shell, and the saturating pipe limit plate of abdomen is slideably
It is inserted into inner passage, and is provided with inclined guiding groove on respective outer surface；

In the abdominal cavity of one piece of saturating 2 partial insertion patient of pipe limit plate of abdomen at end.It is always positioned in two pieces of saturating pipe limit plates 2 of abdomen
Guiding device shell 1 is to be provided with intensive fiber fur 22 on the inner surface of outer portion.The width of two pieces of saturating pipe limit plates 2 of abdomen
The sum of degree is greater than the half of 1 length of guiding device shell.The inner surface of the guiding device shell 1 is arranged side by side along its length
There are three convex ribs 15, forms the limit sliding chutes being adapted with the saturating pipe limit plate 2 of corresponding abdomen between any two adjacent convex ribs 15.
Referring to Figure 1 and Fig. 2, data line 4 and power supply line 5 are respectively arranged in the two sides of the unlock flexible axle 3.Institute
The head end for stating data line 4 is equipped with CCD camera 6, to acquire the situation in abdominal cavity of patients.The head end of the power supply line 5
LED cold light source 7 is installed, the shooting for CCD camera 6 provides illumination.It may also be noted that the tail end of data line 4
Data connector is installed, is connected by data connector with display, the image in abdominal cavity of patients can be showed to medical staff,
Also, it can also be powered by the data line 4 for CCD camera 6；The tail end of LED cold light source 7 is equipped with power connection, leads to
Power connection connection power supply is crossed, is powered for LED cold light source 7.In addition, CCD camera 6 can also replace with light according to the actual situation
The equipment such as fibre probe.
Fig. 2 and Fig. 6 are referred to, is provided in the inner passage 11 and is respectively used to location data transmission line 4 and power supply
The harness locating clip 14 of line 5, with fixed data transmission line 4 and power supply line 5.It is pointed out that flexible axle guide chute 13, harness
Locating clip 14, convex ribs 15 are reliable and stable with 1 one-pass molding of guiding device shell.
Application method of the invention is as follows:
Method one: being first in the locked position the saturating pipe limit plate 2 of two pieces of abdomens, is then inserted into peritoneum dialysis catheter guiding device and suffers from
Person abdominal cavity adjusts the position of peritoneum dialysis catheter guiding device, makes peritoneum dialysis catheter guiding device according to the image that CCD camera 6 is passed back
The predetermined position for placing peritoneum dialysis catheter 8 is reached, saturating 2 part of pipe limit plate of one piece of abdomen for being now placed in top can be located at patient's body
Outside, peritoneum dialysis catheter 8 is connect down from the abdominal cavity for being inserted into patient between the saturating pipe limiting slot 12 of abdomen and the saturating pipe limit plate 2 of two pieces of abdomens
Come, according to the image that CCD camera 6 is passed back, finely tunes the position of peritoneum dialysis catheter guiding device and peritoneum dialysis catheter 8, peritonaeum is saturating
After analysing the guidance to pelvic cavity bottom of pipe 8, medical staff pulls unlock flexible axle 3, and the saturating pipe limit plate 2 of two pieces of abdomens is located remotely from each other to Xie Suowei
It sets, peritoneum dialysis catheter 8 is no longer limited by peritoneum dialysis catheter guiding device, finally, only by peritoneum dialysis catheter guiding device from patient's body
Extraction.
Peritoneum dialysis catheter 8: being first placed in the saturating pipe limiting slot 12 of abdomen by method two, then operation unlock flexible axle 3 or between grasp
Make the saturating pipe limit plate 2 of two pieces of abdomens, be in the locked position the saturating pipe limit plate 2 of two pieces of abdomens, clamps peritoneum dialysis catheter 8, lead to after the completion
It crosses peritoneum dialysis catheter guiding device to substitute into peritoneum dialysis catheter 8 in the abdominal cavity of patient, according to the image that CCD camera 6 is passed back, fine tuning
The position of peritoneum dialysis catheter guiding device and peritoneum dialysis catheter 8, after the guidance to pelvic cavity bottom of peritoneum dialysis catheter 8, medical staff is drawn
Dynamic unlock flexible axle 3, the saturating pipe limit plate 2 of two pieces of abdomens are located remotely from each other to unlocked position, and peritoneum dialysis catheter 8 is no longer drawn by peritoneum dialysis catheter
Device limitation is led, finally, only extracting peritoneum dialysis catheter guiding device from patient's body.
It may also be noted that either using method one or using method two, guided using above-mentioned peritoneum dialysis catheter
Device can only need to carry out local anaesthesia to patient, without general anesthesia, and a lesser handle hole only by navel, relatively
Pipe operation (needing to open a hole with patient) is set in the minimally invasive laparoscope of tradition, has and spends low, convenient, single wound of operation etc.
Feature.
Finally, it should be noted that foregoing description is only the preferred embodiment of the present invention, the ordinary skill people of this field
Member under the inspiration of the present invention, without prejudice to the purpose of the present invention and the claims, can make multiple similar tables
Show, such transformation is fallen within the scope of protection of the present invention.
